Flowcytometric technology has been widely used for measurement of the absolute numbers of T-lymphocytes subsets in Human Immunodeficiency virus (HIV), defining the disease state, monitoring antiviral treatment, and identifying any risk for opportunistic infections. A manual preparing of the samples is required. More recently an automated and enclosed blood cell counting, Celldyn Sapphire has been introduced. In this study the performance of the Flow cytometer EPICS XL as a reference method for analysis of CD3+, CD4+ and CD8 T-lymphocytes was evaluated with blood from 40 individual?s samples.

This thesis aims to examine the phenomenon of gambling and consequences that may result from having a gambling problem. The thesis also intends to investigate opportunities for support and a few explanatory- and treatment models. Games are taking on new shapes and access to gambling for money is on the rise. Studies on gambling have primarily been focusing on epidemiological factors rather than factors increasing or decreasing the risk of developing gambling-related problems. The empirical material is based on eight qualitative semi-structured interviews.

Abstract The purpose of this study is to further understand swedish highschoolstudents perspective on the subject of history. In order to produce an answer a series of qualitative interviews were conducted with six students of mixed ages, ethnicity an gender.

This study investigated relationships between high level language functions and phonological working memory in adults by correlating results oftests in a test battery used for investigating subtle language disorders and digit span task results. Results of two digit span tasks were analyzed in relation to demographic factors. 103 subjects without neurological disease, 20 ? 79 years old, participated. Significant correlations were found between the digit span tasks and most of the tests.

In sectors with high skill requirements, recruiting is a core part of a company's development. Initially, the companies attract talented employees by creating an interest in the organization. Further, the challenge remains to match potential workers expectations with the company?s requirements and conditions. This is crucial since an unsuccessful recruitment involves high costs.

The building sector accounted for around a fourth of the total energy usage in Sweden in year 2010 (Energimyndigheten, 2012). Therefore it has become very interesting to achieve a lower energy usage in residential buildings. One way to achieve that is to build so called passive houses. By being very well insulated and have low leakage through the walls, they can reduce the energy usage for heating with a substantial amount. The first passive house was built during the 90?s in Germany; and in Sweden the first passive house was built in Gothenburg 2001.

Along with the rapid expansion of wind power in Sweden during the last decades the competition about favorable areas has hardened. This among other reasons has caused the projectors to look into development of wind power in forests. There are several aspects regarding fatigue loads on the constructions that are severe in complex terrain, among which turbulence is one. The levels of turbulence which are accepted in order for the turbines to face a life length exceeding 20 years are regulated by the International Electrotechnical Commission, (IEC). In order to keep the turbulence below these levels there are three major steering tools to use: The ambient turbulence decreases with height and can therefore be regulated by the hub height of the turbines.

AbstractThe purpose with this study was to get knowledge if there are any possible differences in, and correlation between, experienced stress, experienced demands, experienced control and experienced social support in correlation to shiftwork.The study was made at two central hospitals in south of Sweden and had 90 participants (78 women and 12 men) that answered a questionnaire in the current variables. The result in experienced stress showed that there were no differences between shift workers. The results showed a difference between the day- and the nightshift in the correlation between control and stress. The writers speculates that the reason why the nightshift experience high stressvalues with high control can depend on the lack of presence by higher managers, compared with the dayshift. .

Stress is something that has increased in recent decades among adolescents. Several reports indicate that young people today are more stressed because of the many demands they wear. They should be good in school, achievement expectations, get an education or job, make choices and think about their future. The purpose of our essay is that we want to explore and gain an understanding of how young people in the third grade in high school looks to stress. To conduct this study, we used a qualitative approach, by doing interviews with 10 high school students attending third grade at Västerviks gymnasium. The result we got out of the interviews was that young people experience stress differently, depending on their different as individuals. We found that there are different causes of stress, such as school, media, friends, demands from various quarters and choosing education.The interviews showed that some kind of stress was possible to handle for the adolescents, for instance by making schedule. Some stress from society was, on the other hand, more difficult to avoid..

The purpose of this study is to examine and compare librarian profession with different professional theories. The intention is to describe how the librarian profession meets the different professional criteria and to what extent the librarian profession can be said to be professional in expertise, service and autonomy. Nolin?s modern theory provides an opportunity to analyze occupational groups based on professionalized basic concepts. The analysis of relevant material showed that the librarian is a service profession with high skills, but does not hold a high degree of autonomy.

According to the theory of environmental Kuznets curve there is a relationship between carbon emissions and GDP. The relationship has an inverted U-shape. Carbon emissions rise initially and then decreases once a certain level of GDP is obtained.This essay interprets earlier studies in the field of environmental economics and uses public choice to seek answer on how the population acts on aggregate level. This essay analyses 115 countries in cross-sectional data. The analysis shows that there is a significant relationship between carbon dioxide emissions and GDP that is increasing at first and then decreases for a certain level of GDP.

To build a sustainable future should we first understand that; every aspect of our daily lives can affect the environment. It?s important that we take responsibility for understanding how we impact the environment and change our actions accordingly. The worlds total energy consumption equivalent to 80 million MWh / year. This corresponds to about 220 million MWh / day.Energy consumption is one of the main reasons for increased greenhouse gases when the reduction of this consumption has a great demand worldwide.In order to prevent the energy that consumed the buildings must be energy efficient but there is a conflict between radon ventilation and energy conservation in a building, given that ventilation can consume as much energy (currently 29-59% of energy-efficient houses use), especially in a cold climate as in Norway.

The objective of this thesis was to get more knowledge before an alternation of generations. In theses I have chose to make two drawings, one for dairy cows and one for cattle rearing. The drawings are made for a future alternation of generations at my parental home in the province Dalarna. The results are made out of educational visits at different farms and literature investigations. Those dairy farms who I visited had different milking system at each farm and the cattle farm I visited had beef production. The farms are placed in the middle and south of Sweden. At 1998 the Swedish Board of Agriculture decided to change the stall breadth and stall length and the result of this is that many farmers had to rebuild their cattle- and dairy buildings or end farming..

The forest property Fagerdal 2:10 was donated to the Swedish University of Agriculture in 1995 by Erik Rönnberg. The dominating species is Norwegian spruce (Picea Abies) and the average age is high due to selective cutting. The aim of this study has been to analyze how the forest on the property should be managed and demonstrate how a better estimated forest data affects the future management. The impact of the management on the carbon stock of the property was also examined. A forestry plan established in 2009 by Skogssällskapet was used as a basis for the analyses.

AbstractWith increasing population and increasing demands for comfort and thus an increase in energy demand, it is necessary to examine various energy-efficiency measures. This work deals with the ability to control the flow through the heating system to achieve the desired comfort with as little energy as possibleA heating system contains of different parts, roughly speaking, you can divide it to three main components: Heat source, Distribution and Heat emitters. All components are working together to bring heat to the building. What is examined in this report are different ways of adjusting the flow and supply temperature and how it affects comfort and energy use in a building.At today ?s date the conventional method is to use a high flow through the heating system, which affects pressure drop and cooling of the fluid.
