Tensile Hair Strengh

Once the hair had been rated or not it was then carefully placed in a sticky note to be wrapped up, making sure not to twist or bend the hair. Weights were then hung of the hair to test the strength of each, once snapped the amount they could hold was recorded. Null hypothesis: Hypothesis: There is a significant positive correlation between the strength of hair that has been heated and the strength of hair once it has been conditioned. Research: Human hair is a natural fiber that is made up largely of a protein called keratin, 80% of hair is formed by this protein.Keratin contains a high concentration of sulfur which is produced from the amino acid Sistine. Rationale: Many women and some men are obsessed with hair care routines and mirroring sleek shiny hair styles like celebrities. The fixation with malignantly shiny hair and being able to alternate between styles has had a massive effect on the cosmetic Industry. With a number of people using straightness, curling Irons or hairdrye rs dally many cosmetic companies such as Tiresome and Pentane have benefited from creating products that help create this look and malting healthy hair.Although the companies claim that these products work this Investigation will look Into whether or to the products actually help maintain strong healthy hair or if once the hair has Variables: Independent variables: * If the hair is treated with conditioner or not – controlled by making sure to separate the treated group from the untreated group and not containment. Dependent variables: * The size of weight – controlled by using the same size weights each time (each weight was log) and making leg weights to make it more precise. To make the leg weights they were measured on a scale that was accurate to 0. 1 g Control variables: * Amount of time in oven – controlled by using a stopwatch to be sure that the hair as heated for a precise amount of time * Amount of time in conditioner – controlled by using a ti mer, didn't want one strand of hair receiving longer time in treatment than others as may cause an anomaly if one hair was stronger than the other * The person who's hair was used – controlled by using the hair from the same person, also making sure the hair hadn't come to any previous damage from dying the hair or daily usage of heat appliances.Preliminary work: For the preliminary investigation I started by gathering my samples of hair from the bottom of the scalp at the very back of the hair. The hair had been washed the night before to ensure that any dirt or hair oil had been washed out, however conditioner had not been used. Once the hair had been removed I measured each length along a ruler to make sure each was the same length, each piece of hair was then cut to CACM long. To make sure my results were more reliable the hair was also cut from the bottom of the strand so that all the hair was the same and because the bottom of the hair was already weak this was cut off. In total I had 20 pieces of hair each cut to CACM. Once this process was complete I divided the hair into two groups . Hair that would be heated – this was marked by a section of the paper it was laid out on having an orange mark. Paper it was laid out on having a red mark. After being divided into the two different groups I heated both groups with hair straightness (GAD). The ceramic plates heat up to 204. 4 degrees Celsius, although the straightness get extremely hot I realized there was room for human error.The length of time that the straightness spent on the strand of hair could differ between each length and on each section of the hair due to the time that the straightened was pulled along. Due to there being a high percentage of human error I used a different technique to heat up the hair to eradicate it. Instead of heating the hair with straightness I decided the best way to get the same heat across the whole length of hair and all the strands of hair was to heat them in the oven.I set the oven temperature to 205 degrees Just slightly higher than the God's, once the oven was heated to the temperature set I quickly put the strands of hair into the oven trying to decrease the time the oven door was open and so decreasing the amount of heat that the oven lost. After timing the hair in the oven for 2 minutes I took the hair out and started to test the strength of the hair against results I had taken previously from hair that hadn't been heated to make sure that there was some change when heated. The results hadn't changed much and so I decided to heat the hair for five minutes.Once the hair was heated for five minutes I divided the two groups. Once separated into two groups the hair was laid on separate pieces of paper each color coded to ensure I didn't mix the ones that would be treated and the ones that wouldn't. I then kook all the strands from group two and using my fingers coated them in conditioner. Improvements: The advantage of doing a prel iminary test enabled me to assess any errors that could implement the final results and also to check if the methodology I was using would be suitable for this investigation.The hair had originally been heated by using hair straightens however there was considerable room for human error due to how long each strand of hair was in contact with the irons. The improvements made on heating the hair was to heat them collectively in the oven, the time they were kept in he oven was also tested during the preliminary to ensure they received the same amount of heat as a strand of hair would when being treated with a heat appliance.

The economy of the early Roman Empire

The economy of the early Roman Empire and the late Republic of Rome was driven primarily by trade. Although in modern times history the economic basis of the Roman Empire has been neglected and focus has been directed to the exploits of the Roman Legions and Lingua France of Latin, it is important to note that Rome had an estimated population of over a million and to sustain its population, the economy had to be centered on a central avenue and this avenue was trade.Most of the Romans were traders and this ensured that the empire lasted a long time, probably one of the longest lasting empires the world will ever witness[1].Theoretically, there was a prohibition of the members of the senate to be indulged in business and this also applied to their family members. However, the Equestrian Order members were hugely involved in business not withstanding the fact they belonging to the upper class, the society expected them to be involved more in leisure and military activities and pursuits .There were also a huge proportion of slaves who were responsible for doing most of the work while the Plebeians practically held shops and manned stalls around the vicinity of the markets.The slaves were also involved in the commerce of the empire and they played a great role in giving the empire's commerce a distinct flavor compared to other commerce in the world[2].Thesis StatementThe study will focus on the Roman Empire involvement in the Mediterranean trade and how this trade was conducted and how it benefited the Roman Empire. The study will look in the Maritime routes that were present during the trade and how they helped in the development of trade among various regions in the world including Asia, India, Africa and Western Europe.The study will also strive to look into the regions that benefited from the various commodities of the trade and how they came to be powerful empires as well. This study will look into the ancient Roman trade partners and what commodities were exch anged during the trade.The Study will also look into the importance of certain commodities to the Roman Empire and chief among them will be marble.Maritime RoutesArchaeological studies of the ancient maritime trends supported by manuscripts derived from Classical antiquity have proved that the Roman Empire was in possession of numerous fleets of ships. Also as a show of evidence of the maritime trade conducted by the Roman Empire are the ruins and remains of lighthouses, moles, harbors and warehouses which were found in the ports of Caesarea Maritima, Ostia, Civitavecchia, Leptis Magna and Portus.As with other forms of technology, the Roman maritime technology was not as advanced as that of the Greeks. It is evidence that the Roman fleets were constructed with great concern about the security of the fleets.This is because there was lead sheeting for hulls which were meant for protection. They used sailing ships which were round hulled. One of the factors that led to the success of t he Roman Maritime Commerce was the continued policing that run over a number of centuries. This was necessitated by the fact that their ships had been an easy prey for the pirates[3].The sea transport was widely used for transporting of commodities which were low valued yet very bulky. This mainly comprised of construction materials and grains. One of the reasons for this was that the sea transport was the cheapest mode of transport that the Roman Empire could afford. They used to import cereals and papyrus from Ptolemaic Egypt and this followed a continuous fashion[4].The Roman Empire trade via the Indian Ocean blossomed in the first two centuries of CE. The Roman sailors would make use of the Monsoon winds to cross to such ports as Myos Hormos, Roman Egypt, Red Sea Muziris and Malabar Coast. The Tamil dynasties were their leading trade partners the region of Southern India and this can be evidenced by the numerous Roman artifacts that are found in India.[1] Donkin, Robin A. (2003) .

Strategic Human Resource Management Essay Example | Topics and Well Written Essays - 3000 words - 2

Strategic Human Resource Management - Essay Example Thus, this paper presents different forms of discrimination alongside the related case of the famous footballer, John Terry, who was once involved in a racial kind of discrimination. To start with, discrimination at the workplace can be on the basis of racial differences. Racial discrimination is the act of looking down upon somebody in the workplace due to his race, color or ethical origin. This kind of discrimination can emanate during hiring and firing. For instance, one applies for a job that he or she has excellent qualifications, but he or she is not hired because the rest of employees are not confortable dealing with somebody from that race. It can also be evident in payment, whereby a fellow employee of a preferred race at the same level of management with the same expertise as one from a discriminated race earns more (Dipboye & Colella, 2005). Secondly, religious discrimination in workplace is a common scenario especially in organizations that are conservative and run on a religious basis. Religious discrimination is basically looking down upon somebody in their employment because of their religion, beliefs and practices. This kind of discrimination can be manifested during hiring and firing. Some organizations might opt to hire employee from a certain denomination and not the other thus creating unhealthy working conditions. Religious discrimination can also be in form of harassment based on religious belonging. Gender discrimination is the main and most common misconduct in employments all over the world. Gender discrimination is differential treatment of an individual in their workplace just because they are male or female. This kind of discrimination is evident when a certain gender is preferred for a certain job. For instance, the fact that the company’s long term serving clients are confortable dealing with men, a woman might be fired. The company management may attribute this firing to cutbacks and reorganization but

Broken Windows Essay Example | Topics and Well Written Essays - 500 words

Broken Windows - Essay Example The theory postulates that when public behavior in a neighborhood is unregulated, it leads to the gradual â€Å"breakdown of community controls† (Kelling and Wilson, 2, 1982). The ‘broken window’ here is symbolic of the breakdown of the informal controls through which people regulate public behavior in a neighborhood. The shared civic obligations and mutual considerations of community living act as barriers to crime and disorder. Once these barriers are overcome by the perception that ‘no one cares,’ vandalism occurs. Social controls are weakened and citizens feel that the environment in uncontrolled. This generates fear. Such an area, with its ‘broken windows, is particularly vulnerable to the spread of crime and disorder.   When disorderly behavior remains unchecked, it goes on to become criminal. When police apply the ‘Broken Window’ theory to specific actions on the street, they aim to â€Å"elevate --- the level of public order† in the neighborhood (Kelling and Wilson, 1982). The role of the police is to maintain order. It is acknowledged that disorder and crime are interconnected in a community. The police’s role is founded on this link between order-maintenance and crime-prevention. Their role is based on the premise that â€Å"serious street crime flourishes in areas in which disorderly behavior goes unchecked† (Kelling and Wilson, 2, 1982). It is a reflection of the police’s role in earlier periods, when the main responsibility of the police was to maintain order. Actions such as keeping drinking away from the main intersections, questioning strange loiterers, preventing panhandlers and vagrants from bothering pedestrians and begging at bus-stops, keeping noisy teenagers in check, and settling disputes between customers and busi nessmen are geared towards the maintenance of public order. Arresting a single drunk or vagrant

Comparison Between Two Films Assignment Example | Topics and Well Written Essays - 1750 words

Comparison Between Two Films - Assignment Example As most of the world, particularly the U.S., was trying to overlook the threat posed by the Germans and the discrimination of the Jews, Charlie Chaplin and the rest of the actors spoke up loudly against the discrimination in a humorous way (Maland 34). What makes these two films similar is the fact that they were both comedies that used humor to uncover and condemn the faults in the German political system. This paper will analyze two scene from each film and compare them to the other in aspects of their narrative structure (themes, characters and acting) and cinematography. On the second scene of the film, we observe the main actors of the last show, Joseph and Maria Tura, now acting in Hamlet. The two chat, and Joseph tries to convince Maria that he truly loves and adores her (Eyman 2). When he enters her room, he becomes overly jealous when he realizes that she has gotten flowers from a secret admirer for the third day in a row. After Joseph leaves the room, Maria informs her maid that she is sure they are from the attractive aviator, but reassures the maid that she too loves her husband, but he becomes offended by such small things. From this scene, we can see that Marias attitude appears to be that of a careless female who enjoys taunting men and making her spouse overly jealous. She appears to have few good motivations in life other than to be admired and loved (Eyman 2). Even as the movie continues, we observe that Maria only grows and matures when her country is in danger. Joseph, on the other hand, acts like a silly, haughty man when we initial ly see him. They have numerous passionate, but childish, arguments with Maria as they act, which makes us unsure of their matrimonial. Joseph becomes overly jealous and angry after and instead of acting like a gentleman, he turns into a raving lunatic for a while (Eyman 3). The central theme in this scene is

Humanities Essay Example | Topics and Well Written Essays - 750 words - 7

Humanities - Essay Example In most occasions, the immigrants try as much as possible to expand their civilization and cultural practices into their new colony in order to dominate. Various factors contributed towards the occurrence and expansion of colonization in the world. For instance, most Europeans colonized Africa because of not only prestige, but also because of the fertility of Africa. As early as 15th century, the European nations were entering the industrialization phase, and as a result, they required raw materials for their industries. Psychological challenges also affected the Europeans significantly. This is evidenced by their pride; they believed that they were superior to other races, and as a result they colonized other races in the world. Lack of common religious practices in other parts of the world such as Africa also enhanced the movement of the Europeans into Africa. It was through this movement that the remote parts of Africa were colonized. However, countries were not colonized at one specific time; various parts in Africa for instance were colonized at different times and by different European nations. For instance, East Africa was colonized by the Germans, North Africa by the Portuguese, and the French and English colonized North America. The Germans started having their way into East Africa in early 1880s by first invading into Tanganyika. They later advanced to other East African nations, Burundi and Rwanda in early 1890s. They success in expansion in Africa was enhanced by the presence of the Catholic missionaries who claimed to educate, convert Africans as well as provide medical care to the natives of East Africa. Despite their exploitation of resources, the Germans also contributed significantly towards the development of East Africa’s economy. This is evidenced by their involvement not only in the planting of cash crops

Reasons for the Decline in Union Membership and Density in the 21st Research Paper

Reasons for the Decline in Union Membership and Density in the 21st Century - Research Paper Example Over the past decade, unions have used their political clout to advocate legislation and establish regulatory agencies that supersede entirely or greatly circumscribe the scope of collective bargaining on many issues of significance to employees. When deciding whether or not to form or join a union, workers balance the costs of doing so, such as union dues, against the expected benefits, such as better working conditions and pensions. While the costs of joining unions are seemingly unaffected by most labor legislation, the potential benefits of doing so decline. Because they are already buying labor protection and mandated fringe benefits with tax dollars, workers have less incentive to join unions. The political success of unions in the past has surely played some role in undermining their future prospects, as in the case of VBY union. It is no secret that labour unions have been declining in membership and influence for many years. The number of unionized workers in Europe was only 16.7 million in 1990, which is approximately 16 per cent of the workforce. This is less than one-half the per cent unionized in the mid-1950s. Some managers view the decline of unions with glee. To them unions are non-productive, combative adversaries interfering with the harmonious and efficient operation of the company. Some of them have adopted the idea that this is pay-back time for the punishment management suffered in the sixties and early seventies when rising wages, automatic cost of living adjustments, ever-increasing benefits, strikes, and Byzantine work rule arrangements seemingly were the rule.  

Comparative Analysis of Free Market Economy and Mixed Economy Essay

Comparative Analysis of Free Market Economy and Mixed Economy - Essay Example The essay â€Å"Comparative Analysis of Free Market Economy and Mixed Economy† highlights main advantages and limitations of the two prevailing economic systems in a modern world. An economic system comprises the configuration of institutions and organisations that specify property relations within a given society or that channel and influence the distribution of goods and services. In a traditional economic system, there is no control and everyone can produce goods for themselves. The countries which follow this economic system have low GDP and they have high government regulation of business. On the other hand, a planned economic system is the one where all economic activities are planned by the government of the day. The government has the overall say in how businesses should operate. A free market economy is defined as â€Å"a market without any regulation. In other cases it means markets in which prices are free to reflect supply and demand. Sometimes it means competitive markets free of monopoly or concentration. In a free market economy system, individuals are encouraged to produce and make gains for themselves and the economic system is driven by profit motives. It can also be seen that price mechanism determines the allocation of resources. For instance, the law of demand and supply comes into play. A free market economic system has its own limitations A mixed economy is regulated and its performance is mainly determined by the economic policies promulgated and implemented by the government. ... It can also be seen that price mechanism determines the allocation of resources. For instance, the law of demand and supply comes into play. Basically, in a free market economy, the quantity of products offered in the market is mainly determined by the amount of price the consumers are willing to pay. Kotler and Armstrong (2004) state that the price people are willing to pay for a certain commodity correlates with the quantity of goods supplied. In economics, the law of demand and supply states that the price of the product shapes the quantity of goods that can be produced at a particular period. This law goes on to state that the higher the price, the higher the goods the producers are willing to supply (Benassy, 1988). High price means high supply of products and this entails that high profits are likely to be generated. On the other hand, a mixed economy is a combination of a free market and planned economies. A mixed economy is regulated and its performance is mainly determined b y the economic policies promulgated and implemented by the government. To a certain extent, it can be seen that a free market economy is effective compared to a mixed economy. According to Pryor (2006), countries with a business-oriented or free market economic system have a significantly higher rate of economic growth. The main reason for this is that they can generate more revenue from free trade taking place. Unlike in a regulated economy, a free market economic system is liberal and the flow of money is not restricted. In a free market economy, the consumers have a variety of choice of goods offered since the manufacturers of these commodities are mainly concerned with satisfying the needs of the customers. As long as the consumers are willing to pay the price,

Any topic that includes microeconomics Term Paper

Any topic that includes microeconomics - Term Paper Example Tariffs have adverse effects on an economy. However, governments continue imposing them on investors who import commodities from foreign nations (Gregory 2000 p 16). This essay is a critique of the economic implications of tariffs. It highlights the major reasons why governments impose tariffs on imported goods, which include; protection of the emerging as well as aging and incompetent local firms from unhealthy foreign competition, to enhance sustainability of local companies through prevention of dumping effect from foreign companies which may offer their products locally at an extremely low price that leads to losses by domestic firms (Mansfield and Yohe 23). The essay also presents the negative views of tariffs in regard to promoting trade and economic growth, which have been supported by various organizations such as the WTO and Word Bank. The double impact of tariffs on the economy imposing the tariffs as well the economy on which the tariffs have been imposed is highlighted. The impact of tariffs on the prices of locally manufactured goods, changes in demand for the goods and employment in the economy imposing the tariffs has been illustrated using the United States as an example of an economy imposing tariffs on foreign products from china (Swire 2009), and the Republic of Korea which illustrates an economy that does not impose taxes on foreign products in the domestic market. The essay also indicates the invisibility of the negative impacts of tariffs on the economy compared to the projected advantages. It also indicates the areas that need further research regarding tariff imposition, whereby researchers can search for information from published sources. One of the major reasons why governments impose tariffs on imports is to enhance the development of the emerging domestic industries to attain a size that able to cope with foreign competition. In other words it is one of the

Goals of Bureaucracy Essay Example for Free

Goals of Bureaucracy Essay Bureaucracy is an organizational or governmental structure wherein the regulations and principles are set in a specified and rigid way to control the activities within a group. Bureaucracy follows a standardized set of procedures which its members are expected to follow in order to execute tasks. Bureaucracy is highlighted by its distinct characteristics which put emphasis on hierarchy, division of powers and relationships which translate to a formal political influence within the organization. The modern day practice of bureaucracy is set to towards reaching predetermined goals by sticking to rigid policies. Bureaucrats are expected to follow certain rules and regulations in order to ensure a smooth work flow within the organization (â€Å"Bureaucracy and Adhocracy,† n. d) Bureaucracy under different types of government works either for the benefit of the people, or their demise. As such, there are certain values that bureaucrat representatives must take into account in order to efficiently provide for the needs of the majority. There are different values which bureaucrats must be able adhere. These values are efficiency, accountability, neutrality and responsiveness to citizens among others. However, I personally believe that among these qualities and goals that a bureaucratic government must adhere, accountability and neutrality are two of the most important. Accountability within a government body is always important. Government bodies are elected because the majority of the people have chosen them represent their needs in the society. And as such, in a bureaucracy or in any other form of government, the importance of putting the people first is always a necessity (Mises, 1969, pp. 42-60). Accountability, if observed within a government translates into the other goals that bureaucracy should be accounted for. If government officials or bureaucrats will hold themselves accountable for the needs of the people, then they also render themselves responsive to the needs of the people who entrusted the government into leadership. Further, neutrality within the government system is equally as important. Leaders of a nation must, at all times, maintain neutrality – between the rich and poor; majority and minority. In this way, the rights of every individual for a fair and just treatment in the society will never be less prioritized. The right to fair treatment in the court or in the peoples daily lives is one of the most important aspect that a government or organization must provide to their people (Mises, 1969, pp. 42-60). Failure to provide the people with these two – accountability and neutrality – any government body or organization will function less properly and less effective in addressing the needs of the people. In addition, failure to make the people feel that the government is neutral in dealing with their people, and if the people felt that their government is less accountable to their needs and rights, people lose the trust they have for their government. Losing the trust of the people means that the organization itself is not efficient and is not effective into delivering the needs of the people. Thus, accountability and neutrality are two of the most distinct and important goals that any government or bureaucracy must instill. Accountability and neutrality, if put into practice, shall guide the government and the people to work efficiently together. These two values will render the government or organizational body the credibility towards the people under their rule. And as such, credibility shall also earn leaders respect and trust from the people.

Challenges Faced By Medical Laboratories Information Technology Essay

Challenges Faced By Medical Laboratories Information Technology Essay Healthcare is always a top priority within any collection of individuals, whether it is the workforce, schools, churches, communities, states, countries etc. This is because mortality rates are directly affected by the level of healthcare available, and effective productivity is dependent on good health and high mortality rates. Developed nations tend to invest large sums of money into healthcare, in order to prevent most ailments before they become epidemics, however, due to lack of emphasis on the importance of healthcare, African nations suffer from low mortality rates caused by lack of proper laboratory procedures and equipment, to test and accurately diagnose problems ahead of time. Even though we are now in a highly advanced technological era, Nigerian hospitals still conduct tests, data collection, and calculations manually, leaving a huge opening for errors which could lead to wrong diagnosis and in turn, wrong treatment. As we humans become ever increasingly dependent on computer technology in our daily lives, it then would be appropriate to utilize technological solutions to problems conventional methods prove inefficient at. These problems can be solved with the use of a properly configured software system to manage all administrative tasks in the laboratories. The most effective use of technology to solve to these issues would be carried out using open source software popularly known as a Laboratory Information System (L.I.M.S). The model of this work seeks to provide an application which will enable vital functionalities such as proper documentation and storage of patient information, patient specimen/sample tracking, and most important, patient test results. In the light of the above, the proposed system applies the web application development approach in its information architecture and processing, however this system will run on a local machine as opposed to running on a remote server over the internet. Consequently at completion of this work, the end product should be a Laboratory information management system which handles activities in the lab from the entry of a patient to the laboratory to the generating of a test result or Laboratory report. BACKGROUND OF STUDY The study for the development of the laboratory information management system uses a medical laboratory facility: Bakor Medical laboratory as its case study. Investigations indicate that the following steps or procedures are undertaken in the process of getting tested in the medical laboratory. On entry into the laboratory a document known as the Patient Investigation form. This form holds information such as the Patients name, age sex, on filling this form the patient is then billed. The patient Investigation form is then transferred to a second laboratory attendant who then uses the information retrieved from the aforementioned form to fill the laboratory request book. STATEMENT OF THE PROBLEM In recent times, due to increase in population, there is constant pressure on providers of various services to provide innovative methods of dispensing a sizable amount of services to great amount of people in the shortest possible time. Consequently, organizations are constantly resorting to technological solutions to meet up with the ever increasing demand for quality and speedy service delivery and with virtually everything in our day to day lives being technologically driven, should there not be a scenario where paper documentation is completely annihilated from medical laboratories?, where a system is adopted in which patient records and data are properly stored such as to enable features such as patient/visitor history tracker, where a returning patients history can aid the laboratory in deducing what type of test a visitor would request for, statistical reports generation where useful statistical information is inferred based on test results e.g whether or not there is an incr ease or decrease of new HIV infections, should there not be a software/application where other stakeholders in the health-care delivery processes such as doctors and pharmacists have access to laboratory generated information to aid in their health-care administration?, should the retrieval of patient test records be slow and cumbersome?, why must results be entered directly on the result document, therefore a backup copy is unavailable. Questions such as these will serve as a guide to the development of a robust system than manages various tasks in the medical laboratory. 1.3 RESEARCH QUESTIONS Based on the statement of the problems above the research question for this study are: How will the development of a laboratory information management System greatly increase the laboratorys efficiency? OBJECTIVE OF STUDY To design a robust Laboratory information System that will efficiently aid in the running of the laboratory facility To hold and provide timely information about each visitor to the laboratory To reduce the need to hire staff through the proper application of technological solutions therefore cutting cost. With a proper functioning and comprehensively designed application, Laboratory tasks such the following can be achieved: SAMPLES MANAGEMENT A LIMS can automate the management of samples. An organization can configure its analytical parameters and calculations into the LIMS before implementing the software in the laboratory. After sample registration, the system can print barcodes which it can scan at the end of the analysis when loading results into the LIMS. The system can check the completed results, automatically validating those which comply with specifications; and reporting (but not validating) out-of-specification results. A LIMS may release or retain lots and batches, according to a laboratorys specifications and calculations. Once results come available for the labs clients or owners, they can extract them in  PDF, XML  or spreadsheet files from the LIMS interface. (Note that moving insufficient data to a spreadsheet may lose the traceability of changes). LABORATORY USERS One may configure a LIMS for use by an unlimited  number of users. Each user owns an interface, protected by security mechanisms such as a login and a password. Users may have customized interfaces. A laboratory manager might have full access to all of a LIMS functions, whereas technicians might have access only to functionality needed for their individual work-tasks. ADMINISTRATIVE TASKS AUTOMATION As of 2009  LIMS implementations can manage laboratory sampling, consumables sampling schedule and financial (invoices). SCOPE OF STUDY Bakor Medical centre has various departments and sections based on the issue at hand to be dealt with; however this study focuses mainly on the lab processes, including data collection and management. This study takes the patient from the moment of entry into the medical centre, filling forms, up till the moment the test is taken, from that point onwards the study will focus on the methods used by the laboratory attendant to collect and store data, through recording of findings and submission of results This study will also concentrate on data backup and retrieval methods and will highlight potential errors and problems that could be encountered if the entire process was carried out manually instead of using a well configured computer application. SIGNIFICANCE OF STUDY The Computer based Laboratory information management System is quite desirable as it will benefit the laboratory in the area of repetitive task automation. It will serve as an assistant to the medical laboratory scientist. It will also benefit patients as they will be able to retrieve record from previous visits to the laboratory. LIMITATIONS OF STUDY The limitations of this study include: Inability to obtain actual test result document, as this goes against medical ethics for a third party to view Laboratory specimen or test results. Unavailability of qualified laboratory scientist at the study locations to properly explain terms and laboratory procedures. LITERATURE REVIEW From tasting urine to microscopy to molecular testing, the sophistication of diagnostic techniques has come a long way and continues to develop at breakneck speed. The history of the laboratory is the story of medicines evolution from empirical to experimental techniques and proves that the clinical lab is the true source of medical authority. Three distinct periods in the history of medicine are associated with three different places and therefore different methods of determining diagnosis: From the middle ages to the 18th century, bedside medicine was prevalent; then between 1794 and 1848 came hospital medicine; and from that time forward, laboratory medicine has served as medicines lodestar. The laboratorys contribution to modern medicine has only recently been recognized by historians as something more than the addition of another resource to medical science and is now being appreciated as the seat of medicine, where clinicians account for what they observe in their patients. The first medical diagnoses made by humans were based on what ancient physicians could observe with their eyes and ears, which sometimes also included the examination of human specimens. The ancient Greeks attributed all disease to disorders of bodily fluids called humors, and during the late medieval period, doctors routinely performed uroscopy. Later, the microscope revealed not only the cellular structure of human tissue, but also the organisms that cause disease. More sophisticated diagnostic tools and techniques such as the thermometer for measuring temperature and the stethoscope for measuring heart rate were not in widespread use until the end of the 19th century. The clinical laboratory would not become a standard fixture of medicine until the beginning of the 20th century. Ancient diagnostic methods In ancient Egypt and Mesopotamia, the earliest physicians made diagnoses and recommended treatments based primarily on observation of clinical symptoms. Palpation and auscultation were also used. Physicians were able to describe dysfunctions of the digestive tract, heart and circulation, the liver and spleen, and menstrual disturbances; unfortunately, this empiric medicine was reserved for royalty and the wealthy. Other less-than-scientific methods of diagnosis used in treating the middle and lower classes included divination through ritual sacrifice to predict the outcome of illness. Usually a sheep would be killed before the statue of a god. Its liver was examined for malformations or peculiarities; the shape of the lobes and the orientation of the common duct were then used to predict the fate of the patient. Ancient physicians also began the practice of examining patient specimens. The oldest known test on body fluids was done on urine in ancient times (before 400 BC). Urine was poured on the ground and observed to see whether it attracted insects. If it did, patients were diagnosed with boils. The ancient Greeks also saw the value in examining body fluids to predict disease. At around 300 BC, Hippocrates promoted the use of the mind and senses as diagnostic tools, a principle that played a large part in his reputation as the Father of Medicine. The central Hippocratic doctrine of humoral pathology attributed all disease to disorders of fluids of the body. To obtain a clear picture of disease, Hippocrates advocated a diagnostic protocol that included tasting the patients urine, listening to the lungs, and observing skin color and other outward appearances. Beyond that, the physician was to understand the patient as an individual. Hippocrates related the appearance of bubbles on the surface of urine specimens to kidney disease and chronic illness. He also related certain urine sediments and blood and pus in urine to disease. The first description of hematuria or the presence of blood in urine, by Rufus of Ephesus surfaced at around AD 50 and was attributed to the failure of kidneys to function properly in filtering the blood. Later (c. AD 180), Galen (AD 131-201), who is recognized as the founder of experimental physiology, created a system of pathology that combined Hippocrates humoral theories with the Pythagorean theory, which held that the four elements (earth, air, fire, and water), corresponded to various combinations of the physiologic qualifies of dry, cold, hot, and moist. These combinations of physiologic characteristics corresponded roughly to the four humors of the human body: hot moist = blood; hot dry = yellow bile; cold moist = phlegm; and cold dry = black bile. Galen was known for explaining everything in light of his theory and for having an explanation for everything. He also described diabetes as diarrhea of urine and noted the normal relationship between fluid intake and urine volume. His unwavering belief in his own infallibility appealed to complacency and reverence for authority. That dogmatism essentially brought innovation and discovery in European medicine to a standstill for nea rly 14 centuries. Anything relating to anatomy, physiology, and disease was simply referred back to Galen as the final authority from whom there could be no appeal. Middle Ages In medieval Europe, early Christians believed that disease was either punishment for sin or the result of witchcraft or possession. Diagnosis was superfluous. The basic therapy was prayer, penitence, and invocation of saints. Lay medicine based diagnosis on symptoms, examination, pulse, palpitation, percussion, and inspection of excreta and sometimes semen. Diagnosis by water casting (uroscopy) was practiced, and the urine flask became the emblem of medieval medicine. By AD 900, Isaac Judaeus, a Jewish physician and philosopher, had devised guidelines for the use of urine as a diagnostic aid; and under the Jerusalem Code of 1090, failure to examine the urine exposed a physician to public beatings. Patients carried their urine to physicians in decorative flasks cradled in wicker baskets, and because urine could be shipped, diagnosis at long distance was common. The first book detailing the color, density, quality, and sediment found in urine was written around this time, as well. By a round AD 1300, uroscopy became so widespread that it was at the point of near universality in European medicine. Consequently, the clinical laboratory became a standard fixture of medicine at the beginning of the 20th century; it is now an integral part of the health-care delivery process and is seen as the basis for medical diagnosis. In recent times a medical laboratory scientist (MLS), formerly known as a medical technologist (MT) or clinical laboratory scientist (CLS), functions as a medical detective, performing laboratory tests that provide physicians with information that assists them in preventing, diagnosing and treating diseases and maintaining patient wellness.   The medical laboratory scientist performs a wide variety of laboratory tests, ranging from simple dipstick urine tests to complex DNA tests that help physicians assess risk of diseases. Using test results, physicians can uncover diabetes, cancer, heart attacks, infections and many other diseases.   Medical laboratory scientists interact with physicians, nurses, pharmacists, and other members of the healthcare team to provide timely, accurate information so the patient can receive the correct medical treatment.   Medical laboratory scientists use sophisticated biomedical instruments and technology, microscopes, complex electronic equipment, computers, and methods requiring manual dexterity to perform tests on blood, body fluids, and tissue specimens. Clinical laboratory testing sections include clinical chemistry, hematology, Immunohematology (Blood Bank), immunology, microbiology and molecular diagnostics. EFFECTS OF MEDICAL LABORATORIES Medical Laboratories have played a pivotal role over the years. As stated above, in ancient times, physicians relied on various inaccurate means of disease diagnosis such as urine tasting, listening to the lungs etc. However with the advent and subsequent evolution of modern medical laboratory facilities, plus the discovery of the cellular nature of human tissue and the invention of the microscope, medical diagnosis made a tremendous leap from a 50-50 accuracy ratio to an 80% accuracy rating for laboratory based medical diagnosis. Therefore the use of medical laboratories has greatly increased the accuracy of diagnosis; hence the physician can administer the proper kind of treatment. The use of laboratories has also led to various discoveries, such as new strands of Viruses, bacteria, parasites and fungi. It also acts as a monitor for new strands of drug resistant bacteria. CHALLENGES FACED BY MEDICAL LABORATORIES The main challenges and bottle-necks encountered by medical laboratories over the years include. Inability to preserve patient samples or specimens such as blood, sputum, stool, over a long period of time for reference purposes hence making patient to specimen matching and tracking, Efficient information sharing and retrieval between the laboratory scientist and those administering treatment has been a problem. MEDICAL LABORATORIES: IMPROVEMENTS AND THE FUTURE For the efficient functioning of the diagnosis system, health-care delivery, scientific research into bacteriology and disease causing organisms, technology should be applied to automate administrative tasks, such as the visitor registration and result documentation. By making judicious use of computer software to automate and manage tasks in the laboratory there will be a dramatic increase in its efficiency. Consequently this will greatly reduce the need to recruit and pay personnel to carry out administrative duties therefore such resources can be channeled towards more important needs of the laboratory. TECHNOLOGY PLATFORM/PROGRAMMING LANGUAGE TO BE USED IN STUDY The technologies to be used in the development of this Laboratory Information Management system is an open source programming language known as PHP, together with a MYSQL driven database, a solid browser based application will be developed. PHP: PHP also known as Hypertext Pre-processor, it belongs to a class of languages known as middleware (Needham, 2006). These languages work closely with the web server to interpret the request made from the web, processes these request, interact with other programs on the server to fulfill the request and then indicates to the web server exactly what to serve to the clients browser. It is the leading web programming language for design of web applications. It possesses a language similar to C, Java or Pearl. Its uses include: retrieving user input and saving it in a database, retrieving information from a database and general data manipulation processes. THE CLIENT: Simply refers to end users of an application that connect to a remote server to carry out computational processes THE SERVER: An application known as a web server listens for requests a client makes, responds to those requests and serves out the appropriate response (Greenspan, 2002) MYSQL: Refers to an open source relational database management system with a set of programs that access and manipulate these records. (Descartes, 2003). It is a  relational database management system (RDBMS)  that runs as a server providing multi-user access to a number of databases. APACHE WEB SERVER: Apache is a web server notable for playing an important role in the initial growth of the world-wide web. It is responsible for accepting Hypertext Transfer Protocol (HTTP) request from web client (web browsers) and serving the HTTP responses along with optional data content which usually are HTML pages. These platforms are used in this research work because: There are open source meaning there are free to use and develop with without having to purchase licenses or fulfill any legal obligation to the owners of the technology. It is easy to deploy on a local machine Its hardware requirements are minimal therefore making its installation and usage less cumbersome. Developer tools and support services for the platform/technology are readily available at absolutely no cost. DATA COLLECTED FOR LABORATORY TEST Lab Investigation Form: This form is used for general patient registration and data collection. Data collected on this form include Patient Name Patient age Hospital Number Specimen Blood Specimen Sputum Stool Urea Various Swap Investigation Record Clinic Details Name of Doctor Lab Request Book: Used to record Patients data for that day. Name Lab Investigation Done Amount Time in Data Collected for lab tests Lab result book (Used for recording patients results) Patients Name Date of birth Gender Test Results Date Hospital registration Number Extra Comments SUMMARY The use of technological solutions greatly reduces costs, increase profits, save human effort and provide better services to customers/clients The use of an LIS (Laboratory information System) in the running of a medical laboratory facility greatly improves the documentation process; makes patients records retrieval a lot easier and faster, records are not lost and are kept safe via regular backup of the available data. With the use of a Laboratory information system, various kinds of data deductions, surveys and reports can be easily generated for statistical purposes such as the average percentage of persons with a certain kind of disease, Genotype or blood type etc. CONCLUSION A properly developed Medical Laboratory information system will greatly increase productivity, increase the quality of services delivered by the facility and greatly reduce the amount of man hours put into the delivering the laboratory services

Ineffective Breathing Pattern: NANDA-I, NIC, NOC

Ineffective Breathing Pattern: NANDA-I, NIC, NOC Ineffective Breathing Pattern Informatics is defined as the collection, classification, storage, retrieval, and dissemination of recorded knowledge (Merriam Webster Online Dictionary, 2014). Moreover, nursing informatics is defined as a specialization of nursing that revolves around the characteristics of data, information, and knowledge combined (CCN, 2014). The progression of the three characteristics mentioned, coupled with the application of wisdom, serve to provide the framework for nursing informatics’ metastructure (CCN, 2014). Nursing informatics, although often unrealized, is utilized in a myriad of ways by nurses to not only support the work that they do, but to also aid in the decision-making process for patients and other healthcare providers such to achieve favorable outcomes, (CCN, 2014). One very important example of how nurses use informatics is through the utilization of nursing terminology. According to Hardiker (2012, p. 112), â€Å"nursing terminology serves as a vehicle to permit nurses to capture, represent, access, and communicate data, information, and knowledge. In addition, a standardized nursing terminology is a nursing terminology that is in some way approved by an appropriate authority, or by general consent; In North America, one such authority is the American Nurses Association â€Å". The following paper is a detailed review by the author regarding a nurse-patient scenario as it flows through three standardized nursing terminologies: NANDA, NIC, and NOC while subsequently being critiqued against the metastructure of nursing informatics, mentioned above. In conclusion, the author will summarize this paper by drawing the sections of the paper together and offering his own perspective gained through this experience. Ineffective Breathing Pattern: NANDA-I, NIC, NOC NANDA International, Inc. (NANDA-I), the Nursing Interventions Classification (NIC) and the Nursing Outcomes Classification (NOC) together provide a set of terminology to afford comprehensive, research-based, standardized classifications of nursing diagnoses, nursing interventions and nursing-sensitive patient outcomes (NNN, 2014). NANDA-I serves as a nursing terminology that maintains an agreed set of nursing diagnoses organized as a multiaxial taxonomy of domains and classes (Hardiker, 2012, p. 113). According to Bulechek, Butcher, Dochterman, and Wagner (2013), â€Å"NIC is a comprehensive, research-based, standardized classification of interventions that nurses perform. NIC covers physiological and psychological interventions. As with NANDA-I, NIC interventions are organized into classes and domains†. According to Moorhead, Johnson, Maas, and Swanson (2013), â€Å"NOC is a comprehensive, standardized classification of patient/client outcomes developed to evaluate the effe cts of interventions provided by nurses or other health care professionals. As with NANDA-I and NIC, NOC’s outcomes work in unison to assist patient outcomes†. As a nurse on a medical/surgical/telemetry floor this author encounters a very diverse range of patients with a plethora of morbidities; one very common admitting diagnosis is: Ineffective Breathing Pattern. â€Å"I can hardly breath and I’m scared; it seems as if this is getting worse, please help me†. NANDA-I defines an ineffective breathing pattern as: inspiration and/or expiration that does not provide adequate ventilation (Ralph Taylor, 2011). Patient X has respirations of 32, pulse of 118, a blood pressure of 145/92, and presents with nasal flaring, and her lips are pursed as she has an increased focus on trying to breathe while currently on 3 liters of oxygen via nasal cannula. Pt. X’s health history reveals a retired patient with end-stage COPD, obesity, and she has been a smoker for well over thirty years; her COPD has worsened through the years and she has developed an increasing level of anxiety. Pt. X has been admitted to the hospital several times o ver the past several years with similar complaints; however, over the past six months her condition has worsened. Applying NIC to this scenario it is suggested that the nurse encourage slow, deep breathing, have the patient sit up in bed, turn frequently and cough; the nurse is to monitor respiratory and oxygenation status, as appropriate. In addition, the nurse should ascertain whether the patient’s dyspnea is physiological, psychological, or a combination of both. Last but not least, applying NOC to this patient scenario, the patient through utilization of the NIC interventions, the patient will report the ability to breath comfortably and demonstrate the ability to perform pursed-lip breathing to assist controlling her breathing; moreover, her vital signs will fall into normal ranges: respirations less than 20, pulse less than 100, and a reduced blood pressure that is near her baseline which is 120/80. As a result, the patient should be able to vocalize less stress related to her breathing, and understand how to alleviate future episodes ((Ralph Taylor, 2011). In a textbook situation, referring to the nursing standard terminologies of NANDA-I, NIC, and NOC should provide a foundation for assisting one’s patient encountering an ineffective breathing pattern. Data, Information, Knowledge, and Wisdom A familiarity regarding standard nursing terminologies provides an excellent reference for nursing; however, a large majority of nurses have a limited knowledge or experience with standard nursing terminologies (Schwiran Thede, 2011). Remarkably, having a familiarity with diagnoses, interventions, and outcomes is only that, a familiarity. A good nurse recognizes that a text-book definition and guidelines are simply tools to assist in the overall care for one’s patient. By placing Patient X’s scenario into the nursing informatics’ metastructure, care for one’s patient base can be greatly enhanced. First, one has to account for the raw data: increased respirations, increased pulse, increased blood pressure, and a heightened anxiety level. It is very important when providing patient care to remember that data, by itself has no particular meaning (CCN, 2014). Second, by retrieving all recorded data for patient X, reviewing trends, and placing her current data in contextual review allows a nurse to convert this raw data into information (CCN, 2014). A review of patient X’s data reveals that her current assessment presents data that exceeds her normal baselines. Third, by taking into consideration patient X’s physiological data as well as her physiologic and psychological presentation coupled with the nurse’s working knowledge base and experience regarding the information presented, this nurse recognizes patient X as having an ineffective breathing pattern. Last but not least, wisdom is realized by not only having an appropriate knowledge base to address the patient’s current health scenario but the skill-set, experience, and critical thinking skills of knowing when and how to take action (CCN, 2014; McKie, et al., 2012). Conclusion According to Robert and Petersen (2013), â€Å"Nurses must be able to think critically to face the challenges of today’s burgeoning technological advances, and ensure safe passage and positive outcomes for patients†. The referenced quote sums up the writing of this paper’s message and the realized experience while writing this paper by its author. Nursing is a very complex profession that has many tools to advance and evolve. By reviewing patient X’s condition, applying it through the nursing terminologies of NANDA-I, NIC, and NOC, and subsequently reviewing it against nursing informatics’ metastructure one can clearly understand that there are many platforms available to properly assist in the care for not only patient X, but our community at-large.

Public and Private sectors joins hands to undertake a project. Public and Private Partnership may be defined as A corporate venture between the Public and Private sectors, build on the expertise of each partner that meets clearly defined Public needs through the appropriate allocation of resources, risk and rewards. PPP is a joint venture of Public and Private sectors and collaboration between Public and Private sectors. The PPP depend on the expertise of both the Public and Private sectors. PPP is a contract that involves a contract between Public and Private sector in which Private sectors provide a Public services/Projects and assume substantial, financial, technical and operational risk in the project. PPP is a step toward involving Private sector and to hold them accountable for input. PPP address peoples needs clearly through the appropriate allocation of resources, risk and rewards. PPP is growing day to day because it is an efficient way of delivering the Public services to the masses. ADVANTAGES OF PPP: Some of the advantages are Diversification of Risk. Efficiency. Cost effective ( time and money saving). Creation of value added goods and services. Accountability for provision of quality services. Effective utilization of state assets. Innovation and diversity in Public Private services. DISADVANTAGES OF PPP: Disadvantages of PPP are Complexity of the Project. A construction delay in the projects. Operational difficulty. Financial risk.(the risk that the project dont get funds/finance). Commercial risk (Demand and payment risk). Changes in Exchange rates. Regulatory (Changes in laws like tariffs) Political situation. Force majeure (Natural disasters). TYPES OF PPP MODELS: Different types of PPP models are Service contracts. Management contracts. Leasing contracts. Concession contracts. Green field contracts. Build, Operate transfer contracts. In design build finance contracts. Now a brief overview of these contracts and their strengths and weaknesses. Service contracts: Service contracts is a contract between public agencies and private sectors and is suited for simple and short term requirements. It is the limited type of PPPs model. In this agreement the Private party procure operation of an assets for short period. The period of two to five years. In this contract the responsibility for investment and management of the project are of the Public sector and also bears the financial and residual value risks. While the Private sector provides the services. Potential Strengths: The main advantages of service contracts are It provides us relatively low risk option for the expansion of Private sector. It is less expensive to deliver the public services. It encourages the competition the Private sector. It is a good source of technology transfer. It is less costly. Potential weakness: The main disadvantages of this contract is It is a short term contract/project and is not suitable for to pool up capital. Loss of managerial control. Loss of flexibility. Loss of internal and external focus. Loss of competitive edge. Management contracts: In this type of Contracts the responsibility for the operation and management is passed to the Private sectors. The life of these types of contracts are from three to five years but can be extended. The Private sector/party is remunerated/hired on a fixed fee basis or on the incentives or bonuses basis linked to a related or specific task. In these types of contracts the Public sector bears the financial and investment risks. This is an efficient way undertaking a project because the Private sector is efficient and have enough skills and strong interest in improving the service quality. Potential strengths: The main advantage of these contracts are that the ownership remains with the Government and only the operation and management is transferred to the Private party. Management contracts are less controversial in nature. These types of contracts are less expansive because the Private sector is more efficient and can do the job betterly than the Public sector because of the experienced and skilled management. Potential weakness: Some of the major disadvantages of management contracts are The government gives a certain portion of control to the Private sector which may lead to low quality services. Delay in time. The flexibility in these contracts are finished or reduced. The quality of the product is reduced. The Private party must be clearly evaluated for best performance. Leasing contracts: Leasing means when one party lesser gives his assets to another party lessee on some fixed payments. In leasing the Private party purchase the income streams generated by the Public owned assets for an exchange of fixed leased payments and the Private party is responsible for maintenance and operation of the assets. The duration of leasing is from ten to twelve years. Leasing contract is best for Infrastructure development. Potential strengths: The leasing finance is a fixed rate finance. Leasing is inflation friendly. Through leasing and this contract brings efficiency in the Public service delivery. In leasing contracts the Private sector competitively bid for the lease means providing the services to the general people. The increase in the leasing contracts is almost due to the improved and new technology. Potential weakness: As we know that the leasing contract is based on the streams of payments/installments made by the Private sector but if the Private sector doesnt make payment in time than a problem arises and one of the main disadvantage of leasing contract for the Private sector is that the responsibility for maintenance and capital investment is of Private sector. Concession contracts: Concession contracts is a type of leasing contracts in which the ownership of the assets remain with the Government and the Private party is responsible for the maintenance of the assets and also to provide the capital investment and at the end or completion of the project the Government receive the project and pay a certain sum of amount to the Private party according to the contract. In these type of contracts the Government gives concession to the Private sectors to explore some thing like oil and gas. Potential strengths: The advantages of the concession contract is that it mobilize the funds/capital from the Private sector for the construction and exploration of existing projects. In concession contracts the Government assets are properly utilized and maintained by the Private sector efficiently and after completion the Private sector gives the project/assets to the Government and the Government pays a certain amount of money to the Private sector according to the contract. Through bidding the contract Government creates competition among the Private sector which leads to low cost. Potential weakness: One of the major disadvantage of this contract is that the timing/validity of these projects are more and these contracts are long term contracts which leads to complexity. The maturity of these projects are more than 20 years. Due to the longer period it is difficult to manage and organized. It requires complex monitoring and design system and also reduce competition because a few big Private contractors are available. Green field contracts: These types of contracts are mostly used for the development of new projects. In these type of contracts the government only provide the land to the private sector. Examples of Greenfield contracts are projects like new factories, airports, development of parks which are build from scratch. Potential strengths: In green field contracts the Government only provide the assets and the Private sector build, design, develop and manage the assets. It is used for developing the new projects like parks and airports etc. Build, operate transfer contracts: In these types of contracts the Private party is responsible for the designing, constructing and the operation of the assets. In these types of contracts the government bears the financial risk but have control to stop the project at any stage. These types of contracts are best for water and wastage projects. BOT has the following types. Built own operate transfer (BOOT). Built lease operate transfer (BLOT). Built rent operate transfer (BROT). Potential strengths: The risk is shared with the Private sector. Due to the efficiency in the Private sector the Government gives projects to the Private sector. The Private sector is responsible for the design, construction and service delivery. The Government gives these types of projects mostly to the experienced and skilled Private sectors. It also facilitate the transfer of advanced technology by introducing international contractors in the host country. It is an effective way to bring the Private funds for development of new projects like infrastructure and water enhancement development. Potential weakness: Some of the main disadvantage of this contract is that it is not suitable for small projects. The transaction cost in the BOT is higher as compared to the other contracts. The success of the BOT project depends upon the funds raising and when substantial revenue are generated in the project during the operation phase. BOT contracts may be costly some times. In design build finance contracts: In these types of contracts the Private sector/party design the goods and services according to the requirement setted by the Government entities. These type of contracts are best for roads construction and water. Potential strengths: The Private sector contractor is responsible for the design and the construction. Subject to the provision that the contractor is not, under an unamended JCT WCD, responsible for any design provided to him in the Employers Requirements document, the employer should have a single point of responsibility and liability against the contractor. This is more advantageous than the traditional forms of contract where the employer has entered into separate construction and design agreements. A common problem being that if a claim is made, the contractor, architect or other design consultants may argue over the extent of their responsibility. This contract is time saving means that the Private sector are interested to complete the project quickly and is also cost saving and the product is of good quality because the Private sector is more efficient than Public sector and the product is prepared according to the government requirements. Potential weakness: The main disadvantage of this contract is that government mostly give the projects to the large Private sectors and ignores the small Private sector and also reduce the competition through ignoring the small sectors. There may arise the problem of favoritism and also the cost of project may arise through reducing competition in the Private sector and also may arise problems in designing. The perception remains, certainly amongst architects, that design and build is not the appropriate procurement method where design quality is a high priority. There is only limited scope for the employer to make changes to his requirements once the Employers Requirements and Contractors Proposals have been agreed otherwise the cost consequences may be prohibitive. A case of Public Private Partnership of the Melaka-Manipal Medical College: Background: Melaka-Manipal Medical College is the first Indo-Malaysian joint venture in private medical education. The proposal was conceived from the Look East Policy of the former Prime Minister, Tun Dr Mahathir Mohamad. He recognized the need for greater South-South cooperation in the economic and social sectors. This led to the signing of an agreement in New Delhi in 1993, witnessed by both the Prime Ministers of Malaysia and India. The agreement was between the Joint Venture Medical College Corporation (JVMC) Malaysia and the Manipal Academy of Higher Education (MAHE) India to offer a twinning programme leading to the MBBS degree. The objective was to provide additional doctors for Malaysia and offer opportunities for students in this region to study medicine at a cheaper cost than in the West. From 1953 to 1993, Manipal had trained over 2700 doctors from Malaysia. The situation changed in 1993 with the new policy on admission of foreign students to medical colleges in India. Malaysia was s uddenly in urgent need of training opportunities within a minimum lead period. The Melaka-Manipal Medical College seemed to be an excellent idea. The Partnership Process The partners in the Joint Venture Medical College are: State Government of Melaka. Manipal Group. Members of the Indian Diaspora. Contribution of Government of Malaysia Use of Hospitals and Health Centers in two states MMMC is allowed to use the facilities of the General Hospital at Muar and Melaka and Health Centers for the purpose of the teaching and training of students. Teaching Staff Consultants in the hospitals assist in the clinical training of the students. Over 100 consultants work as part time teachers. The Malaysian Medical Council considers the services of 3 part time faculty equivalent to 1 full time employee. Supervisory and Advisory Services The government regulatory bodies i.e. the Malaysian Medical Council and the National Accreditation Board supervise and provide advisory services to ensure maintenance of minimum standards in conformity with government regulations. Financial Assistance to students Government agencies provide scholarship to deserving students admitted to MMMC. Contribution of Private Partners Basic Science Training at Manipal There is a shortage of basic science Faculty in Malaysia hence the excellent facilities at the Manipal Campus India are used for the first phase. Infrastructure for the Melaka Campus Construction of the campus at Melaka including hostel and recreational facilities comparable to the best in the country. Provision of Patient-Care Service MMMC provides faculty to augment patient-care at the hospitals and health centers. Provision of trained medical officers to meet countrys requirement The newly graduated doctor is required to undergo compulsory rotating resident houseman ship for a period of one year. Training of staff in the Health Centers and arranging CME for doctors These activities help in upgrading the standards of doctors and Para medical personnel in the health centers. The CMEs arranged allow doctors to keep abreast with advancing medical knowledge. BENEFITS FOR ALL, A WIN WIN SITUATION: Outcomes and Benefits for Malaysia The Joint Venture helps the health sector in Malaysia to move towards the desired doctor: population ratio in a planned manner. MMMC has contributed 213 doctors in the past two years. Since the clinical training is carried out in Government Hospitals and Health Centers in Malaysia, the graduates are very conversant with the functioning of the government health sector and national health policies. Induction of trained faculty from India augments the specialist manpower in Malaysia. The Melaka-Manipal Medical College would otherwise have drawn a large number of specialists from the Malaysian health delivery system. There is an extreme shortage of teachers in Basic Sciences hence this phase of training is carried out in India. The college helps to create an academic and research environment in the Government Hospitals used for teaching, thus upgrading their quality of care. Benefits for the Students An opportunity to study medicine in a situation where capacity is restricted. Cost of education is considerably less than studying in the western countries. Living on a multidisciplinary university campus at Manipal gives the student a unique cross-cultural experience and builds confidence and independence. The student becomes a part of an esteemed educational system with an international reputation and a worldwide alumnus. The clinical phase is carried out in government hospitals in Malaysia where the students work with patients and staff from different ethnic backgrounds akin to their own. This allows for effective communication and rapport and seamless merger into the environment into which they ultimately will work. Benefit Outcomes for the Private Partners For Manipal, the establishment of the college in Malaysia, gives the opportunities to: Establishing a medical college in the minimum lead period and at favorable costs because of the public-private partnerships. Retain old links with India, having trained 2700 Malaysian doctors in Manipal To establish its reputation and brand name Overseas to acquire the best practices in medical education and health delivery and to prepare for global competition Limiting Factors for A PPP: Medical Education in India is regulated by the Medical Council and the Ministry of Health. The present statutory conditions imposed by the MCI do not allow for the flexibility that is required to foster partnerships between the Public and Private sectors. The regulations are too stringent with regard to ownership and operation of teaching hospitals, For the local partners to share in the thrill of creating an institution in the service of their country and the reputation and financial gains that will accrue in the future. Conclusion of the Case: It has been a very rewarding experience to work with the public sector in Malaysia. Good governance and an enabling environment have allowed for a trickle down effect, in that the value of such cooperative efforts seems to be known to all categories of employees. This facilitates excellent work relationships allowing for a participatory process which is stimulating. The Regulatory process is positive with the correct focus on quality. As an incremental approach Manipal is exploring the possibilities of starting Dental, Pharmacy, and Allied Health Programmes. The success of the venture is due to the pragmatic approach of the Government of Malaysia towards Public Private Partnerships in education and healthcare. Conclusions: From the above discussion and after studying the models of PPP it is clear that The Partnership is not always fruitful for the Government SO a Government should enter to contracts with Private sector after assessing the Private sector efficiency and the Government must have to share the risk with the Private party. If Government does not transfer an appropriate level of risk to the private sector then it should not be availed. But after entering the successful contract with the Private sector the Government can easily deliver quality services.

Essay --

Over the course of this semester I learned a lot about myself as a writer. I was forced to change my thought process, view towards writing, and evaluate my own work over the semester. English 1010 was my first college writing course and it provided me with more freedom than I previously had in high school. During my senior year in high school especially I always felt limited and the topics we wrote about were not relevant. I really enjoyed being able to incorporate my voice in each essay and I believe I developed more of a personal style as time progressed. Lastly by completing this course I accomplished my goal which was to learn the tools needed to produce well written work and become a better writer. While completing each essay other students and I were given the opportunity to engage in peer review. This helped each student by giving other writers the chance to provide their perspective of how the context of the paper can be improved or if it needs additional details. Whether the comments were negative or positive it helps because it is unbiased and can ensures that by correctin...

The Theme of Hope in One Day in the Life of Ivan Denisovich Essay

The Theme of Hope in One Day in the Life of Ivan Denisovich      Ã‚  Ã‚   In Alexander Solzhenitsyn's novel One Day in the Life of Ivan Denisovich, the strong themes of hope and perseverance are undercut by the realization that for Ivan there is little or no purpose in life.   This is not to say that the themes of hope and perseverance do not exist in the novel.   There are numerous instances in the novel where Shukhov is filled with hope. However, these moments of hope amidst the banal narrative of the novel raise the interesting question:   Are these moments of hope pointless?   The answer to this question may lie more in the individual human nature of the reader than in Solzhenitsyn's literary technique.   Whether pointless or not, Solzhenitsyn offers many instances in the novel where the themes of hope and perseverance are evident.   The glimpses of hope which Ivan Denisovich sees includes the few moments after reveille that the prisoners have to themselves, respecting his fellow prisoners, taking pride in a job well done, and enjoying simple food and tobacco.      Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Solzhenitsyn wrote One Day in the Life of Ivan Denisovich in such a fashion that the brutality of the Soviet labor camps is not emphasized.   Instead of focusing on the brutality of the camps, Solzhenitsyn focused on one day in the life of a very ordinary prisoner.   However, the fact that Ivan Denisovich Shukhov is such an ordinary man and is still able to find hope in the most menial of tasks is inspiring.   Joseph Frank states that "Solzhenitsyn's fundamental theme is precisely the affirmation of character, the ability to survive in a nightmare world where mora... ...

Language Essay :: essays research papers

Introduction To awaken from the dream means recognizing the illusory nature of this constricted self concept and perception of the body and mind, not as a means as of gasping at the ephemeral pleasures of the world or as a prison enclosing the self, but as an instrument for learning and communicating in various languages. Before the Move Two months before moving to New York, my friend William, thought he would be kind enough to warn me about the vast culture of the, â€Å"Big Apple.† William begins by telling me that I would not be able to survive the cultural diversity and I would not be able to get a good paying job or housing because of my ethnicity. Well, was he very wrong. Since I commuted to and from New York three times, a week I decided to put in a transfer from the company I was employed with to work in their satellite office in New York. When speaking with Cindy, one of the customer service representatives already living and working in New York, I mentioned to her that I was relocating to the New York office but did not have a place to live. Immediately, Cindy who I did not meet at the time offered me full living quarters with all the amenities for a charge of $445.00 a month. Gleefully, I accepted without even looking at the place. Moving day I had two oversized suitcases and my brother at my side, who kept telling me to, â€Å"You can make it.† Because I was somewhat familiar with my surroundings, it was no problem for me to jump on the â€Å"E† train from Manhattan to Queens, New York. It was not until my brother Jerry and I got to Jamaica Queens that William’s words replayed in my mind. â€Å"You will not be able to survive the cultural diversity.† There were so many people from different cultural background gathered in one place ranging from: Jamaican, Guyanese, Trinidadians, Indians, Hispanics, Caucasians, Blacks and Mexicans. They were shopping, walking, talking, waiting for the bus and catching the dollar vans, going to their different destinations. After I stood there for a moment (relieving myself of the shock), while almost getting knocked down, I called Cindy on my cell phone to let her know I had arrived at the arranged pick-up spot. Prior to that day, when speaking with Cindy, I never knew she masked her Trinidadian accent.

Man Wildlife Conflicts

The problem of Man – Elephant conflict is more severe in the districts of Hassan and Madikeri where large herds of elephants can be seen roaming and marauding the farms especially in or near the forest areas damaging the valuable agricultural crops. At times there have been loss of human lives which only accentuates the problem taking this conflict to an entirely new level. Naturally people can tolerate the loss of agricultural crops but not the loss of their family members.But then who is responsible for all this? It is we who have intruded into their territory, converting the forests into agricultural farms, growing crops and inviting the elephants to our doorsteps to come and have their stomach fill. Its we who have fragmented their habitat by making roads, dams and canals. We have honeycombed their habitat by our so called developmental activities eating into their homelands and this appetite of ours for their areas is only increasing day by day with the bulging human popu lation.The elephants in these areas seem to have a very peculiar habit. First they have their stomach fill. After that they roam around in search of arrack which is usually being distilled in local bhatties. The arrack or the distil waste gives them a nice kick and these drunken elephants are responsible for the loss of human lives. The tools employed by the forest department like bursting of crackers, gunshots or fire torches are too primitive to stop or scare away the marauding pack of drunken elephants.The Man-Leopard conflict is more visible in the transition zone between dry plain lands and the green hilly areas. In the Chikmagalur district it is more a problem in the dry taluqa of Kadur particularly bordering villages of Kadur and Chikmagalur taluqa where the dry tract ends. Kadur is the place which earned a bad name for it about 10 years back. It was here where large number of panthers had to be shot and killed by employing and bringing so called sharp shooters from all over the state in search of an illusive so called man-eater panther.The end result of all this hunting spree was that every day and night several panthers were shot and brought to the post mortem table, post mortem was carried out and the killed panther was declared innocent as no human remains could be detected inside till finally some human hair remnants were detected in one and then only this shooting spree came to a halt. It is debatable whether it was really required to kill such a large number of panthers which is an endangered species but perhaps the department had no means to identify the rrant panther and hence large number of panthers had to be killed in search of that illusive wayward one. Moreover at times one is driven by the urge to be seen as trying his best. Probably this urge opened the floodgates and gradually people took the law into their own hands thinking that why to wait for the forest department when they can themselves teach panthers a lesson. Same happened some time back. A family of a mother panther and its two grown up cubs was seen in the vicinity of a village.They hunted a calf and ate it partially before they were chased away by the villagers. Once they left, the carcass of the calf was nicely poisoned. When the mother and the cub returned unsuspectingly next day, they consumed the remains and in the process died themselves. Leopards by nature tend to stray into the habitations in search of their kill. Their natural prey is becoming rare in the forests and the omnipresent cattle and dogs in the vicinity of the villages on the periphery of forest brings them in close conflict of the human beings.In some other areas also few panthers have had to lose their lives being caught in the snares. These snares are fixed in the barbed wire fence of coffee estates, not necessarily by the estate owners but at times by their labour in order to catch wild boars or smaller animals. However it is the panthers and Sambars who have had to pay the price with their lives for their adventure in to the estates. The Man- Tiger conflicts are by and large restricted to the high forests and the coffee estates in the vicinity of forests in Chikmagalur district.These conflicts also arise due to depredation by tigers on the cattle or getting entangled in the snares fixed in the fencings of the estates. Few tigers have been killed due to such snares. In Chikmagalur, Hassan, Kodagu and other Western Ghat districts Coffee plantations are an integral part of the topography. The conditions available in the coffee estates make them very close to look like forest. Presence of cattle in such areas makes them ideal hunting grounds for the tigers and leopards bringing them in direct conflict with the villagers.Moreover there are large number of authorized and unauthorized muzzle loading guns available making it very difficult for the wild life to survive. Primary reason for all these conflicts is fragmentation of the wild habitat. Whereas few patches have been brought under the Conservation network by declaring them as National Parks or Sanctuaries, about 85-90% of the forest areas are still outside this network. While there can be no doubt that establishing this network has contributed significantly to wildlife conservation. But real problem is that even these networks are also fragmented.Whereas total concentration in these parks and sanctuaries is on wildlife protection making the conditions ideal for wildlife, but what about the wildlife staying in forest areas outside these networks. Wildlife knows no boundaries. Creation of ideal conditions in sanctuaries has helped wildlife to multiply rapidly but where is the additional habitat required to take care of the additional population of animals, which tries to flow over to the adjoining areas only to get killed. This is particularly so with regard to the wild animals having territorial tendencies.There is need to have a continuous conservation network with sufficient area and resources to take care of the progeny. Right now almost no effort is being made to take up wild life related management works outside the parks and sanctuaries. The lands outside the parks and sanctuaries (even inside also) are constantly under threat of encroachment. Honeycombing of the forestlands has already reached extreme. The tools employed by the government in reducing the Man and Wildlife Conflicts are highly insufficient and hence not producing desired results.If we think that paying a few hundred or thousands Rupees to a person as compensation for crop damages by elephants or for a cattle killed by a leopard or tiger would save our wildlife from getting poisoned or shot, then it is nothing but our shortsightedness. Even this so-called wildlife compensation is paid to him after making innumerable trips to the concerned office. The farmer has to forego his earnings for each day he has to visit the office, he has to pay from his pocket for the bus charge and has to undergo ph ysical strain †¦Ã¢â‚¬ ¦.And what he gets is just few hundred rupees. Such hardships discourage him and in the process he gets encouraged to take the law into his own hands and to settle scores with his tormentor- the wildlife. There are only losers on both the sides. The Forest officials are also at times not acting in tandem. There is no coordination among the adjoining units. Particularly in case of elephant herds movements between the adjoining units it can be seen. Everybody wants to drive away the herds to another adjoining unit without giving any thought.It only complicates the problems. Need of the hour is to have a stock of the real problem. And then only solutions can be found. We tend to take each problem in a routine manner. There is a tendency to leave the things to lower subordinates. The powers that be have to take everybody into confidence, discuss the issue threadbare and then have to take a conscious decision. A conscious policy decision need not be essentially sweet and liked by all but it may herald a new era where people and wildlife both can coexist beneficially.

Determination of a Rate Law Lab Report

Determination of a Rate Law Megan Gilleland 10. 11. 2012 Dr. Charles J. Horn Abstract: This two part experiment is designed to determine the rate law of the following reaction, 2I-(aq) + H2O2(aq) + 2H+I2(aq) + 2H2O(L), and to then determine if a change in temperature has an effect on that rate of this reaction. It was found that the reaction rate=k[I-]^1[H2O2+]^1, and the experimental activation energy is 60. 62 KJ/mol. Introduction The rate of a chemical reaction often depends on reactant concentrations, temperature, and if there’s presence of a catalyst.The rate of reaction for this experiment can be determined by analyzing the amount of iodine (I2) formed. Two chemical reactions are useful to determining the amount of iodine is produced. 1) I2(aq) + 2S2O32-(aq) 2I-(aq)+S4O62-(aq) 2) I2(aq) + starch Reaction 2 is used only to determine when the production of iodine is occurring by turning a clear colorless solution to a blue color. Without this reaction it would be very diff icult to determine how much iodine is being produced, due to how quickly thiosulfate and iodine react. Related article: Measuring Reaction Rate Using Volume of Gas Produced Lab AnswersHowever this reaction does not determine the amount of iodine produced, it only determines when/if iodine is present in solution. Reaction 1 is used to determine how much iodine is produced. To understand how the rate constant (k) is temperature dependent, another set of data is recorded in week two’s experiment using six trials and three different temperatures(two trials per temperature change). Using the graph of this data we determine the energy required to bend of stretch the reactant molecules to the point where bonds can break or form, and then assemble products (Activation Energy, Ea).Methods To perform the experiment for week 1, we first prepare two solutions, A and B, as shown in the data. After preparing the mixtures, we mix them together in a flask and carefully observe the solution, while timing, to see how long it takes for the solution to change from clear to blue. We use this method for all 5 trials, and record the time it takes to change color, indicating the reaction has taken place fully. This data is used to find p (trials1-3) and q (trials3-5), to use in our rate law. This experiment concluded that both p and q are first order.The rate constant average of all five trials is used as just one point on the Arrhenius Plot. In week 2, we perform the experiment to test the relation of temperature to the rate of reaction. We start by again, preparing six solutions. We prepared two trials/solutions at 0 degrees Celsius, two and 40 degrees Celsius, and two at 30 degrees Celsius. Again, for each trial we mixed solution A with B, and carefully timed the reaction to look for a color change that indicates the reaction is complete. The interpretation of this data indicated out results of whether temperature has an effect on the rate of this reaction.Results- It is determined that the rate of reaction is dependent on the temperature in which the reaction occurs. The sol utions observed at 40 degrees Celsius reacted at a quicker rate, than those at lesser temperatures, in a linear manor.

Then, once all five values of k are found, the average is taken by adding all five values of k and dividing by 5. The experimental k average is 0. 05894M/s.

To Find the Activation Energy we multiply by the rate constant of 8. 314J/mol(K), which equals -60617. 4 J/mol. We then convert this value to kilojoules by dividing by 1000, equaling 60. 62 kJ/mol. Analysis uncertainty- Due to the limit of significant figures in stock solutions used, the resulting data is limited in correctness. Also, temperature fluctuations during the experiment by even a half d egree would obscure the data of the exact rate constant, k. One of our R^2 coefficients for the experiment was in fact greater than 0. , and the other slightly less than 0. 9 meaning the one lesser is not considered a good fit. The deviation in goodness of fit may have been due to our data recording. Discussion- Determination of the rate law and activation energy of a chemical reaction requires a few steps. By varying the concentrations of reactants it was determined that the reaction is first order with respect to both [I-] and [H2O2+]. Measuring the reaction rate at multiple temperatures allows calculation of the activation energy of the process, in this case the activation energy of the reaction is found to be 60. 2 kJ/mol. As you have seen through all the previous data, charts and graphs, this exothermic rate of a reaction is dependent on solution concentrations, a catalyst, and temperature.
