Individuals of today are living in a community that encourages an inactive life. For many individuals exercise is an important part in their life and can be a health factor and contribute to the joy of living. Some environments in the individuals? everyday life are of supportive character. These supportive environments can make it easier for the individual to make healthier choices.

There are some key elements which distinguish a general operating system, such as Linux, from a Real Time operating system, such as OSE. The later belongs to the category of soft Real Time systems while Linux is a general operating system, with significantly improved real time properties after version 2.6. These improvements make it interesting to compare the two systems.When comparing two operating systems, there are a number of issues which have to be considered. One way to measure the performance of the systems is by studying the time consumption for the same functionality and hardware.During the study, the items that appeared as the most important for the performance of the systems, were: process primitives, system primitives, interprocess communication, context switches and interrupt latency.This work demonstrates that it is possible and reasonable to do performance testing on two different operating systems. The implemented tests cover a number of basic functionalities, which appeared to be the most crucial ones for the performance of the systems..

I dagens samhälle blir det allt mer intressant att spara energi, dels med tanke på miljön och dels föratt minska på utgifterna. Denna energi ska sparas på ett sådant sätt att effekten för användarna blirså liten som möjligt.I denna rapport beskrivs hur ett reglersystem kan byggas för att minska energiförbrukningen hosväxthus genom att reglera belysningen på ett effektivt sätt. Systemet är helt automatiskt vilket göratt användarna inte behöver tänka på styrningen av lamporna alls när väl systemet är uppsatt ochkonfigurerat.För att styra lamporna på ett bra sätt mäts det inkommande ljuset med en PAR-sensor. Lampornatänds och släcks därefter beroende på ljusmängden och även på hur varmt, eller kallt, det är iväxthusen.Styrningen av belysningen sker med en mikrokontroller från Microchip, en PIC18F4620 som ärprogrammerad i C18. Kringkomponenter som portexpasioner, klocka och reläer användes också föratt bygga ett bra reglersystem.Resultatet är att det är möjligt att bygga ett reglersystem med begränsad budget som styr lampornapå ett effektivt sätt.

Abstract The objective of our study was to get knowledge about how teachers think when they make purchases to preschool. Do they consider making environmentally conscious purchases? Do they work actively to transfer environmental consciousness to the children?We chose to interview nine preschool teachers and one cook in two different local municipalities. Our investigation showed that there was a very low engagement in these issues. The teachers said that they were very strictly bound to already existing public contracts and did not see any possibilities to influence the preschools consumption.The teachers hade no idea that not only their work could result in environmental savings in the school, but also result in attitudes changes among the children, their parents and, in the long term, society in general.

Obesity is a problem that increases exponentially in humans and companion animals. It is defined as a big accumulation of fat in the body and is usually connected with several diseases. This study describes how obesity can be diagnosed, in which way the gut flora can affect obesity, if the gut flora is genetically influenced or not, and how it differs between individuals with obesity and obesity-related diseases. Conclusions of the study are that both the bacterial strains Bacteriodetes and Firmicutes probably have a connection to obesity. The intestinal flora is probably also genetically related.

The aim of this paper is to apply Robert N. Bellahs theory of civil religion, within a Swedish societal context. Bellahs theory was designed in, and influenced by American culture. Therefore, the ?translation? of Bellahs theory does not come without problems.

Background: The Swedish life-insurance business has been extensively criticised lately due to broken promises to customers as well as due to scandals that some companies within the business have been involved in. The companies within the Swedish life-insurance business find themselves in a so- called crisis of confidence, something that is created in and by media. A company that finds itself in a crisis of confidence somehow have to manage the situation and crises of confidence can also result in different kinds of changes. Purpose: The aim of this thesis is to explore and analyse how individual life- insurance companies manage crises of confidence. As a consequence, the aim is also to investigate in what way crises of confidence are initiators to change.

Almost for as long as there has been breeding on bovine species, there has been a wish to have a higher proportion of offspring of either one or the other gender. In dairy cattle, heifers are more valuable, while in beef stock bulls are preferred. Semen is sorted based on the difference in DNA content between the X- and Y-chromosome in the genome of the sperm. X-chromosomes contain on average between 3,70 to 4,22% more genetic material than the Y-chromosome. Commercially it is the method of flow cytometry that is being used, which is always under improvement.

The report is a master thesis about energy efficient measures for an underground facility Hemsö fortress.Several proposals are evaluated economically.Statistics of the electricity used and measurements of several heat pumps are analyzed to find energysavings potentials.The results indicate that several units of a dehumidification system are responsible for over 70 % of theyearly electricity cost. The air that is being dehumidified by these units can otherwise cause damage ofculturally important interior designs.The proposal with highest profit suggests an alternative method for dehumidification. The cooler in theair handling units in Hemsö fortress have capacity to dehumidify the air. However complementary fansneed to be installed to circulate humid air towards the air handling units. The solution can be implementedin three different locations within the facility.

The hypocrisy of democracy is to help autocratic rulers to stay in power because it benefits their own country. This thesis examines how the United States of America justified their cooperation with the Iranian Shah Mohammad Reza Pahlavi during the period of 1953-1979, until he was overthrown by his own people. This case-study doesn´t make general conclusions about the US foreign policy towards other countries except Iran.The theoretical starting point for the empirical analysis is the political dilemma of dirty hands. With the analytical instrument, constructed with a normative analysis about the concept of dirty hands, it´s possible to discover which ethical discipline the American presidents had to uphold to justify their actions.There are three different aspects of their cooperation which are lifted in this thesis. The first one is about the circumstances that made them begin their cooperation, the second regards the features of the cooperation.

The purpose of this thesis is to examine how investments are justified in the Swedish data center industry, with a focus on cooling equipment. This is achieved through semi-structured interviews with 20 different interviewees. These interviewees represent different facets of the industry and facilitate an understanding of which factors, such as: investment costs, operating costs, reliability, environmental impact and the influence of external and internal actors, come into play and to which degree they impact the investment decision-making process. The results show that primarily low operating cost in the form of low energy consumption is the driving factor when it comes to the procurement of new equipment. A lower environmental impact is a positive side-effect of lower energy consumption.

It has become more and more common that companies in the service sector are beginning to understand their own effect on the environment and thus the need to contribute to a sustainable development through acting in a deliberate way. Serious environmental work can help a company to improve their image and in that way win competitive advantage that leads to improved profitability. In a short time perspective, adjustment to the environment is an opportunity to gain competitive advantage and an opportunity to develop a profile. In a long time perspective it is about survival. The environmental work has become a sequel to the work with quality.

Studiens syfte var att undersöka om, och i så fall hur, barns konsumtionsmöjligheter påverkar den sociala delaktigheten bland barn i förskola/skola/fritids. Vi ville fånga skolpersonalens upplevelser av fenomenet för att förstå hur detta skulle kunna hanteras. För att svara på syftet har en kvalitativ studie gjorts med hjälp av semistrukturerade intervjuer med personal som arbetar inom verksamheterna. Resultatet visar att barnens konsumtionsmöjligheter till viss del påverkar den sociala delaktigheten. på både gott och ont.

In connection with the property crises in many countries, caused by the financial crises, people are now more aware of the risks involved in poor property-investments. The unusually cold winters along with extreme prices of electricity in Sweden in recent years has also contributed to increased interest in energy-efficient buildings.The process of developing a modern family home in Kiruna, Sweden is presented the first part of this paper. The house has been designed to withstand very high stresses from snow, low energy consumption as well as a high standard of living comfort. Aspects of the house covered here involves everything from construction, heating and ventilation to sanitation. Each of these areas is presented based on their underlying, scientific methods or theories.
