Optimizing energy systems is, in Sweden, as in many other countries, of growing interest. District heating systems are no exception. In 2012, 285 out of 290 municipals in Sweden had district heating in use and the majority of these systems have a higher return temperature than that which is possible with an error-free substation of day current technology. To, when possible, lower the return temperature is a way of increasing the effectiveness of the district heating system.This study means to investigate, through simulations and calculations, how big of a reduction in production cost a lower temperature in the city of Ystad?s district heating system would correspond to.

Over 40 miljon people in the world suffer from hiv/aids today. Africa is the continent that is worst affected by hiv/aids but how is the situation in Sweden? Why is it so quiet concerning hiv/aids in Sweden? Our aim with this work was to find out about the hiv/aids situation in Sweden and particulary in Malmö. The result of our research was that hiv/aids have increased since the year 2000 and most of the people had caught the infection in other countries than Sweden. This raised our curiosity concerning how immigrants/refugees are being treated when they arrive in Malmö and what are being done to stop hiv/aids from spreading further.We became very disappointed when we realised how little that is actually being done and how poorly the collaboration between the institutions are working.

The development aid from Sweden to developing countries is a activity thatinvolves a great deal of monetary founds as well as an opportunity to influence the environmental situation in a partner country. It´s also an opportunity to promote Sweden's values in a field like the environment, setting a good example is important. This thesis aims to evaluate Sida´s environmental policy and find out if there in fact is a Environmental Policy Integration Policy (EPI) taking place. EPI is a policyimplementation theory that emphasise the importance of the total integration of the environmental in the organisation as a whole. To identify this I will use a theoretical framework of indicators invented by William M.

Abstract One of the leading causes of food borne infections in the world is due to Salmonella by con-suming poultry products including eggs and meat. According to US Food and Drug Admin-istration (2009), 2 to 4 million cases of Salmonellosis in humans occur every year only in US. Salmonella causes wide range of diseases with enteric and typhoid fever, food poisoning, di-arrhea and gastro-enteritis. Many serotypes of Salmonella do not have host specificity and cause disease in all kinds of animals and humans. Salmonella has capability to modify accord-ing to the changing environment and it can develop resistance against routine elimination practices of sanitation, chemical treatments and antibacterial drugs. Newly established poultry industries in Pakistan are confronting various infectious diseases including Salmonellosis while in Sweden Salmonella prevalence in animal products con-sumed for humans is extremely low.

In several countries that have been early in the development of wind farms, there is today a second hand market for the used wind turbines. The European Union (EU) has established a waste hierarchy in order to minimize throwaway mentality. The second hand market is a part of this as the steps are to minimize, reuse, recycle, extract energy and landfill.In order to promote the development of renewable energy, there are energy certificates for the producers that provide it, wind power being one type of renewable energy. After 15 years the energy certificates for a specific wind turbine are no longer paid, and after that there are several different scenarios for the wind turbine. The scenarios investigated in this bachelor?s thesis are export of the wind turbine to countries that are not as far along as Sweden in their development towards renewable energy, selling in Sweden to individuals, and recycling of the wind turbine, as it mostly consists of metals and therefore is recyclable.

The special relationship between Israel and the US has been subject to questioning, and good many theories have tried to explain why it is so strong. The most common explanation is rooted in the school of realism, where strategy and national interest decide who one's ally is. This essay aspires to examine another possible reason for allianceformation; identity. Several books, which make for the theoretical backbone of this study, have been written on the subject of sharing beliefs, identifying with others and the consequences of this. The question being asked is whether Israel and the US actually share beliefs and, if so, which ones.

This study focuses on nationalism in Central and Eastern Europe. Anchored in theories that this region historically has been characterized by a nationalism that is based on the ethnic group rather than on liberal or civic concepts, it is the purpose of this study to explore whether these theories still apply in recent times when the region has been liberalized, for example manifested in the entry to the European Union. The research question has been tested through analysis of the constitutions of a number of Central and Eastern European countries in order to investigate what type of nationalism that the states have codified in their basic political documents. The results show that some of the states give expression to the historical ethnic nationalism in their constitutions, which indicates that the theories still are relevant..

In the decades leading up to the First World War, the Swedish army (as the rest of Swedish society) was greatly influenced by Germany (i.e. subject primarily to Prussian military influence). German equipment was purchased and German training methods and ways of organizing military units were copied. Apart from such easily discernible traces of German influence, the Swedish officer corps - according to earlier research - harboured sympathies for Germany and the German Army. But did the German influences, and the sympathies for Germany, also result in a professional bias ? i.e.

The International Organization for Standardization (ISO) proposes vibration standards for the evaluation for machine damage due to vibration in rotational machines, where some vibration parameters are given to measure the vibrationgrade. This work evaluates the relevance of the vibration standards in hydro plants that are proposed by the ISO, and also investigates if there are methods used in other countries could have greater importance. Through statistical analysis of collected data we got a better understanding of relation among different vibration parameters, and also the importance of correct choice of the parameters for the evaluation of vibration. We have found that the vibration standards available today in hydro plants are not reliable for the judgment of vibration?s grade.

This paper analyzes the Swedish labor market during the interwar and early postwar period within the framework of modern labor market theory. The development of unemployment during this period - according to the commonly cited source of labor union reports - represents a conundrum for research. The unemployment rate rose after the initial diverse shock of 1921 and stayed at a permanently higher level for the rest of the interwar period. This development was reversed after World War Two when the unemployment rate decreased and stayed permanently low for the rest of the postwar period until the oil price chock of the 1970s.In a first step the available sources of unemployment statistics is investigated and compared. The general conclusion is that the labor union reports overestimate the level of economy wide unemployment while being a reasonably good indicator of movements in the rate.

Textil- och konfektionsindustrin blir alltmer globaliserad och ställs inför hårdare krav då konsumenterna efterfrågar allt billigare varor i snabb förändring. Sedan flera decennier har europeiska konfektionsföretag flyttat sin tillverkning till länder med lägre arbetskostnader för att uppfylla kraven om låga priser som europiska tillverkare har svårt att uppfylla. En stor del har flyttats till Kina men även till andra länder i Asien. Nu håller marknadsförhållandena på att förändras igen genom tillväxt- och utvecklingsländernas starka utveckling. Förändringarna syns tydligast på Kinas marknad genom stigande priser och mindre kapacitet för europeisk produktion.

This essay examines migration paths through Sweden. There has been a debate in August 2010 that Sweden is regarded as a backdoor for non European immigrants to come over Denmark. It has been discovered through Denmark?s statistics and is regarded as negative by the Danish government. Denmark and Sweden are two countries that are socio- , economically- and culturally similar, but went in two different directions, especially with immigration policy.

The focus of this study is to dig deeper into what motivates volunteer travelers. The commercial side of volunteer travelling has increased in the past years, and young Swedes pay large amounts of money to travel to other countries and work as volunteers. The purpose of this study is to get a glimpse into what motivates these young people, and how this correlates to the rapid increase of commercial travelling bureaus that focus on volunteer travelling. Five people under the age of 30, who had been volunteering through a commercial travelling agency, where interviewed for this study. The results show that the main motivation for paying to go work abroad is actually the experience, meeting new people and seeing new things.

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.

AbstractBackground The importance of establishing well-functioning parent-teacher relationships are clear objectives in the Swedish National Curriculum for Preschools, (Lpfö 98, Lpo 94 & Lgr 11 chapter 1-2). Parental involvement in preschool activities is seen as important for several reasons. Facilitating healthy child development, learning and socialisation are some of these reasons. During the past twenty years Sweden has become a multicultural society. Today, people from more than 170 countries live in Sweden, and about 18% of the population are first or second generation immigrants.
