The cattle production in the world has been questioned in Sweden due to its negative impacts on the environment. The use of imported soya bean meal as a protein feed for Swedish cattle results in the cutting of rainforest and an extensive use of pesticides in the countries were the soya beans are produced. As a consequence, the environmental impacts caused by cattle production increases. A production of protein feeds in Sweden would decrease the transportations and the cutting of rainforest. For organic beef producers the possibility to produce home-grown protein feeds is important since organic protein feeds can be difficult to obtain in another way.

Investment costs for eight different type housing systems for dairy cows has been calculated in order to compare the building costs as a function of herd size, shelter type and automatization. A commercial calculation programme for building was used and complemented with prices of equipments specific for dairy cow building. Herd sizes were 120, 250 and 400 cows. The milking equipments were automatic milking system (AMS), parallel parlour with 32 stalls (2x16) and rotary parlour with 24 stalls. Shelter was either insulated equipped with automatic cable driven scrapers on solid alleys, automatic feed wagon on rails, or uninsulated with manual manure handling and a tractor driven mobile mixer wagon on a drive-through feeding table. Building cost per cow or per kg milk was calculated using an average life time and 6 % interest rate and annual milk yield is 9 500 kg/cow and year. Structure effect 3-4 % higher for an insulated structure than in an uninsulated for 400 and 120 herd respectively. This is much lower compared to what is normally argued.

ABSTRACTIntroduction: Violence towards employees in the psychiatric ward is increasing at an alarming rate. Reports concerning the effect on the staff?s psychological health are disturbing. These workforces are those most affected by brutality and for ages it has been looked upon as a part of the psychiatric line of work. This viciousness is threatening the safety for both the personnel and the patients.

The purpose of our study is to find out how teachers can help their students to learn how to managestage fright. By interviewing high school teachers and high school students and also observe one oftheir classes, we wanted to find out how they think about the causes of stage fright and what youcan do to relieve it. We also wanted to find out how teachers are working to teach students how todeal with stage fright, and how they think that you also could work. As a teacher of music, among other things, the task is to assess and rate the students performancesin music. Several components are based on the students' courage to play on his or her instrument infront of other people.

The purpose of this Masters thesis is to make a critical analysis of Journal Impact Factor JIF. JIF is today the most widespread quantitative measure for evaluating scientific journals. Although it is internationally used and is considered authoritarian many problems have been observed. This has led to that the validity of JIF has been questioned. To identify JIFs limitations the following issues have been raised: Which are the problems with citation analysis? What criticisms have been directed towards Journal Impact Factor as a measure for evaluating scientific journals? The theoretical framework consists of theories about citation behaviour and a discussion about the characteristics of a scientific journal.

Warmer climate is a driving factor to species expansion northwards. Expansion to new areas can result in escape from natural enemies, resulting in reduced levels of mortality and thereby potentially increasing the rate of expansion. The most important parasitoid species attacking butterfly larvae belong to the families Tachinidae, Ichneumonidae and Braconidae. The aim of this thesis was to investigate parasitism and difference between populations in established area and newly colonized area for the European map butterfly, Araschnia levana, in order to examine if the butterfly has escaped from some natural enemies. In 1982 the first European map butterfly was observed in Sweden and has now established up to middle Småland.

Today?s society has become a society of information were communication has become more important to manage, both for companies and for the person as an individual. If you want your message to be successful you have to plan your communication and also evaluate the result. The administration of health and care in Karlstad had already planned and performed an information campaign, ?Vård & omsorg ? Mer än ett jobb? (translation ?Health & care ? More than a job?), and therefore we got the assignment to investigate the rate of success.The investigation is based on both theory and empiric.

In 1993 the internal market within the European Union was formed and ensured free movement of goods, services, capital and people. This led to the removal of trade barriers between members of the European Union. When opening up for competition, price differences between countries decreased and more jobs were created. A single currency was introduced by eleven countries in 1999 with the goal of reducing transaction costs, eliminating exchange rate risk and to further simplify trade. In 2001 Greece joined the collaboration and introduced the euro.

The purpose of this paper is to examine how the target to convert the Swedish military aviation industry towards working within the civilian sector was planned and implemented parallel to the target of building a world-class military aircraft. A number of Government bills have been studied, bills directly connected to the JAS-project as well as bills dealing with civilian project ?s for the military aviation industry. The first group includes bills dealing with the JAS-project ?s role in the overarcing defence policy, as well as the Government ?s bill specifying the guidelines for the JAS-project.

Forecasting stock market returns is an interesting topic since more and more Swedes enter and invest in this market. Theory implies, however, that such exercises should be impossible. The aim of this thesis is to investigate the possibility to forecast future stock returns by looking at macroeconomic variables? history. The study is limited to the Swedish market as it is based on the OMXS30-index which represents the 30 most exchanged stocks on Stockholms¬börsen, the Swedish stock exchange.

 With the increases in fuel costs due to the depletion of the world oil reserves and the increase of greenhouse gasses as a consequence to using oil as a fuel many companies are looking to new and innovative ways to power their aircraft. One of these new ways to power an aircraft is using fuel cells powered using hydrogen and oxygen, thus producing nothing but water vapour and small amounts of nitrogen dioxide as well as trace amounts of other emissions. Both Boeing (1) and Politecnico di Torino (2) have shown that it is possible to build an all-electric aircraft powered by fuel cells. Both flights used small, two-seater aircraft and a constant between them was the loss of the co-pilot seat due to weight and lack of space. As this paper will deal with a commercial aircraft a primary concern is the cargo and passenger capacity and whatever impact switching propulsion system has on these.

The purpose with this report is to give structure to the storage area betweenproduction and packaging at Spaljisten AB in Åseda. The purpose is also to givesuggestions for improvements of work tasks and thereby simplify and improve thematerial handling at the packing process.The background of the task is that Spaljisten AB is going to increase theirproduction and thereby they also need to increase the packing rate of theirproducts. They will manage this by installing a new automated packing line andincrease the efficiency of the old manual one. The theoretical background ismostly obtained from literature which contains relevant facts for our report.The storage area has been studied visually in order to search for improvements oftoday?s layout.

A cochlear implant (CI) is a hearing device that makes it possible for individuals who are deaf or has a severe hearing impairment to receive auditory information and develop spoken language. The pragmatic ability may be affected. In short, pragmatics may be described as the study of language use in social contexts. Pragmatic ability can be seen as the result of the individual?s behavior as well as the underlying causes.The aim of the present study was to describe the pragmatic ability in children with CI.

Marine heatwaves (MHW) have become increasingly common in recent decades due to greenhouse gas emissions that have caused climate change. A marine heatwave is when the sea surface temperature rises, which damage many different ecosystems in the sea. One ecosystem that is sensitive to temperature changes is tropical coral reefs, which are at risk of bleaching during marine heatwaves. Coral bleaching is when its symbionts leave the coral and they lose their color, while also starving to death as they lose their food source. The purpose of this report was therefore to investigate what the connection between marine heatwaves and coral bleaching looks like, and to see if there are any geographical differences.

The union organization rate has continuously diminished since the mid 90's. The aim of this essay is to investigate non-members approach to the union. Central questions are what personal experiences the respondents have of the union and how they view the union as a phenomenon. According to previous research the main cause of the great decline in membership to LO are the increased membership fees to the union and the unemployment insurance funds (UIF) in 2007. The increased fee led to a greater accumulated cost for those who were both union- and UIF -members, which had a negative effect on the membership numbers for the union.
