With increased milkproduction in our dairy cattle, comes a risk for a reduced fertility. Studies performed on animals and humans have shown that it is possible to manipulate the oestrous cycle through exposure to pheromones. This means that pheromones could potentionally be used to make reproduction more efficient. To evaluate the bioactivity of the substances in question, there is need for a bioassay. In insects, pheromones can induce a changed cardiac activity.

Abstract In the contemporary world of information technology you find a multitude of applications and systems covering a broad spectrum of areas of need in different companies. One effect of this multitude of programs is the difficulty to make them exchange information with each other or to collaborate, since they are developed by different programming languages for different platforms, with different standards and different data formats. Our aim with this work is to describe how it is possible to tie these programs together to make them actually communicate with each other in order to exchange information, share their native methods and also to become a part of the overall business processes. In this integration task you will, among other things, find different levels of application integration such as data level, method level, application interface level and user interface level integration. Application integration also involves hardware components, called middleware, that facilitate the physical connection between applications.

The Library of Uppsala University has decided to change their classification system from the Swedish SAB system to the American Dewey Decimal Classification. One of the main reasons for this decison was that Kungliga biblioteket also has made an exchange between these systems. Due to that, the national bibliography of Sweden classifies Swedish documents according to Dewey Decimal Classification and the SAB system is no longer maintained. A transition to Dewey Decimal Classification will enable Swedish librarians to import foreign catalouge posts and classification codes and will provide them with a common standard between their libraries and other libraries due to the use of the same international classification system. It is disputed whether the Dewey Decimal Classification is equally suitable for all subjects.

This master?s thesis will examine the concept of ?fixed establishment? in VAT-law. The concept can be found in the new EC-directive on the common system of value added tax, however it has existed for thirty years in previous directives. Despite this, the legislator has never provided a proper definition of the concept. Its meaning has therefore evolved through the case-law of the ECJ.The Court has put forward a number of criteria which are all to be met if a fixed establishment is to be at hand.

Unemployment amongst Swedish citizens is higher within the group which falls under the designation foreign-born. The aim of this thesis is to examine which municipal factors that can explain the differences in unemployment amongst foreign-born relative to native born.The empirical models are examined with both cross-sectional data for the year of 2010 and panel data for the years of 2002-2012. The examination is implemented through a linear regression analysis of the type Ordinary Least Squares (OLS) and Fixed Effect regressions. A theory section will be presented where the theory on Non-Accelerating Inflation Rate (NAIRU), theories on discrimination and country-specific human capital are illustrated.The result from the cross-sectional data shows that the amount of foreign-born, the level of foreign-born immigrated from Nordic countries have a significant negative effect on unemployment amongst foreign-born. The general unemployment shows a significant positive effect on the unemployment amongst foreign-born.

There are several ways to identify individuals with dry mouth, but there are few studies made in which the different methods have been compared with each other.The aim of this pilotstudy was to compare different methods for identifying individuals with dry mouth. Fifty individuals aged 50 to 75 years were included in this studie. These where randomly chosen among patients at the dental clinic at Kristianstad University College. Four different salivary measurements were conducted: 1) collection of unstimulated saliva, 2) collection of stimulated saliva, 3) the so called ?mirrortest?, and 4) analyse using cottonrolls.

Background: Companies with a high level of research, such as biotech companies, rarely generates any profit in the begining. Mostly their history is short and their pipelines usually consists of one or a few products only. Significant for the line of business is also a future very uncertain, where relevant objects of comparison are few. Altogether the facts above makes valuation of Biotech companies difficult. Swedish Biotech companies, compared to their american competitors, seem to be of relatively low value.

Young people?s political influence has been surveyed, studied and discussed several times in Sweden during the last decade. There is a fear among the politicians that the young people are not interested in politics, especially not in party politics. On the other hand there is, among the youngsters a feeling of invisibility, not being seen or heard or for that sake respected. There are a lot of formal possibilities for young people?s political influence, but there are not as many real possibilities or situations to actually practice these possibilities.

This bachelor thesis is intended to gather the knowledge and experimental data on the winter wheat crop production relevant for Swedish conditions, with focus on sowing time, row spacing and seed rate. This essay is a literature study with a minor component based on interviews with farmers producing winter wheat. The work is divided into a background part where basic knowledge of winter wheat physiology, development and environment interactions are described and one part where results of field trials studies are presented. Optimal date of sowing winter wheat depends on annual weather variations. Because it is difficult to forecast the weather the choice of sowing date should be based on weather statistics, production experience and previous results depending on sowing date.

Biogas is a gaseous fuel, rich in methane, produced through a biological route in an anaerobic digester. A gas engine generates combined heat and power, which can be used at the farm to reduce energy cost. The process also generates a digestate, with better utilization of nutrient compared to cattle manure. The aim of this study is to analyze the profitability of a farm-scale biogas plant for combined heat and power (CHP) at Wapnö. Wapnö is an agriculture company located in the southern part of Sweden.

Saker som glamour, resor, pengar och att få stå i rampljuset lockar många unga till modellyrket. Men det är inte alla som kommer så pass långt att de får ta del av det. Och som med många andra yrken finns det för- och nackdelar och det gäller att inte låta sig förblindas av frestelserna..

Sweden had in the early 1930's the lowest birth rate in the world. Population Commission which was established in 1935 concluded that one of the biggest social problems was the working women?s heavy workload. To deal with the low birth rate reforms and programs were founded both in order to help the women but also in order to support the inadequate motherhood. Government grants were set up to start the so-called vacation home for housewives where the government?s visions of the vacation homes were active rest and recreation.     Based on the Leisure Inquiry report regarding vacation homes for housewives - the purpose of this paper is to examine how the government visions regarding vacation homes for housewives were practiced and how the future of prevailing gender contract affected the holiday home.

This study aimed to evaluate the levels of formaldehyde and organic acids that can build up within enclosed spaces. Another goal was to compare two types of paints that can be used as coating barriers within showcases and in turn compare them to the modern, and by many highly recommended, material of Marveseal®. A low volatile waterborne alkyd/acrylate paint and a two component polyurethane paint was compared to Marveseal® in two series of experiments. One series measured the level of formaldehyde, and thus the effectiveness of the three chosen barriers, and the other series measured the level of volatile organic acids, both the acids emitted from the paint itself, and that of the wood. One box in each series were not treated at all and was used as a reference.The fact that different types of materials emit volatile organic compounds have long been known.

Report of diploma work conducted at the Swedish Radiation Safety Authority (SSM) as part of the bachelors program in Nuclear Engineering at Uppsala University.All nuclear power plants in Sweden are obliged to report any deficiency in their barriers or the defense in depth in obedience to SSM?s regulations concerning safety in nuclear facilities. In addition, there is an international system for reporting such events. The purpose of this thesis is to study the Swedish report system and to analyze the differences between Swedish and international event reporting.In the Swedish system, SSM?s regulations are effectuated by means of event reports classified as category 1-3, designed individually at each Swedish facility.

The essay, based on interviews with eight people, deals with name changes from a foreign-sounding name to Swedish-sounding name. The aim is to investigate the reasons behind the name change and whether experiences of ethnic discrimination were among these reasons. Furthermore, I explore the consequences of the name change, and whether the name change was an effective strategy to avoid ethnic discrimination. The study employs qualitative method; I carry out eight interviews with four women and four men, and analyze the empirical material by means of post-colonial theory in which categorizing, otherness and passing are significant terms. The results show that the name change takes place primarily to reduce a sense of otherness, and the discursively locked positions a foreign-sounding name creates.
