The aim of this literature study was to analyze how milk urea concentration is working as a measure of the nitrogen supply to rumen microbes and indicator of the environmental load. Questions included in this literature study were how to improve the dairy cattle nitrogen efficiency and what correlations there are between milk urea, nitrogen efficiency and crude protein content in the feed. Effects on the reproduction from high ration protein content are also addressed. Dairy cattle are today fed with large proportions of protein which could lead to high expenditure of feed and environmental pollutions. The nitrogen can be lost to the environment by different pathways; leaching, denitrification or by emission to the air.

Recently, the selections of ethical funds are increased; at the same time investors with social and moral preferences have increased in the capital market. There are currently debates on whether ethical funds perform better or worse than funds without ethical criteria. This also involves a vivid discussion on whether investors know about the consequences of investing in ethical funds. Therefore, this study involves theories about the rationality and decision theory, in addition to what mainly control the investment decisions. The study also discusses portfolio theory since this is one of the underlying theories behind fund management and its development.The purpose of this study is to explain if ethical limitations in the selection of securities affect risk and return in the fund portfolio.

Unmanned aerial vehicles (UAV?s) are nowadays greatly appreciated. The advantage over manned airplanes are great since UAV?s can be much smaller and therefore lighter. The goal of this project is to evaluate the performance of an environmentally friendly UAV using only lithium-ion batteries.

Investment in hedge funds is a relatively new phenomenon for investors compared with other forms of savings. In recent years, the interest has increased among investors in investing their money in hedge funds, given the protection against declines in the market they are aiming for. Their main purpose is to generate a high return at a low risk regardless of market trends. This they can achieve by having fewer restrictions that offer more flexible investment strategies and freer investment opportunities.The purpose of this paper is to identify how the selected hedge fund strategies have performed during the recent economic downturn. We also want to clarify the claim that hedge funds exhibit a positive absolute return regardless of what the market is performing.In order to answer the purpose of the essay and its problems, we have used a quantitative method with a deductive approach in the processing of data.

This study is about howStockholm?s policy for zero tolerance of graffiti from 2007 affected the graffiti culture inStockholm. We have researched what consequences there were for the practice of graffiti, and what consequences there were for the stylistic performance of graffiti. In doing so, we have had two focus group interviews and one deep interview including eight graffiti writers from Stockholm. The individuals in the groups have been practising graffiti for a varied amount of time, but we have representation from both before, and after/during the policy of zero tolerance from 2007. Our study shows that the result ofStockholm?s policy for zero tolerance of graffiti for the graffiti culture inStockholmwas a ?subcultureification?, a ?stylistic generalization? and the ?subculture?s ambivalent identity?.

Companies today are expected to communicate their responsibility to the world around them. Society?s expectations differ and stakeholders are demanding that companies act responsibly on matters related to climate, work environment and human rights. The purpose of sustainability reports is that companies should measure, present and take responsibility in relation to their internal and external stakeholders. It is intended that a reasonable picture of the company's sustainability performance should be communicated, containing both positive and negative effects.Companies efforts with sustainability issues is industry-dependent and industries with significant environmental problems perform the most advanced environmental statement.

Today there is still irrelevant pay differential in society. In Sweden in 2010, the average pay differential was 15,4 percent between the sexes. Only 0,8 percent better than EU:s average.In Sweden the individual salaries increasingly have begun to characterize the Swedish labor market. Based on this, the aim of this study is to highlight the issue of equal pay between men and women from the perspective of individual salary. This would also been doing with a background in the regulatory environment of equal pay.When it comes to equality between women and men it is the area of labor law in EU who is the most developed and in Sweden this is the area who is most affected by EU law.

The purpose of this paper was to examine the inflation hedging capabilities of property shares. A common notion is that property is a good hedge against inflation. Indeed, positive correlations have been found for direct investments and inflation. However, property shares are generally perceived as a perverse inflation hedge. This discrepancy has often been quoted as evidence of property shares divergence from the development of the underlying property market.

Records of P III fractures from 235 horses, 71 of them were standardbreds, treated at 3 major Swedish equine hospitals (Strömsholm, SLU and Mälaren hästklinik) between 1994 and 2004 were evaluated for information such as the patients age, sex, breed, type of fracture, affected leg, time and place of the injury, treatment and, if possible, result of treatment. For the standardbreds, result of treatment was also followed up through written correspondence with owners and by screening AB Trav och Galopp racing-results. Moreover, results of horses with type II and III-fractures treated with rest and therapeutic shooing only were compared to horses in which lag screw fixation were added to achieve interfragmental compression. Compared to the rest of the Swedish horse population, P III fractures were slightly more common among standardbred horses. The mean age of the affected standardbred was 5,8 years, compared to 7,9 years in the rest of the horse-population. Most horses injured themselves in the paddock.

In line with Sloan (1996) but on European data (STOXX 600) we are investigating whether stock prices reflect information about future earnings contained in the accrual and cash flow components. The extent to which current earnings performance persists into the future earnings performance is shown to depend on the relative magnitudes of the cash and accrual components of current earnings. Moreover, we still find a significant positive excess return (Jensen?s alpha and size-adjusted return) by replicating Sloans (1996) hedge portfolio by taking a long position in the stock of firms reporting relatively low levels of accruals and a short position in the stock of firms reporting relatively high levels of accruals. However, we find no evidence of negative excess returns for companies with relatively high accruals, this somewhat lower the total excess returns for all the portfolios.

There has been an increasing interest for ranking of Swedish health care and a lot of emphasis has been placed on the creation of indicators in order to rank hospital units. However, essays on to what extent the choice of statistical method affects the final result of the ranking of health care units have not been given the same attention. For this particular reason, the main objective of this essay has been to investigate whether the choice of statistical model has a significant impact or not on the final result, by using five different, more or less common, statistical approaches: bar charts (with and without confidence intervals), control charts, logistic regression, multi-level analysis using shrunken residuals. The analyzed material in the essay comprises 24119 patients that all have been prescribed some form of the lipid-reducing medicine statin. According to directives given by Region Skåne, doctors are encouraged to prescribe a particular type of statin medicine, namely Simvastatin, which has been proved to be equally effective, but significantly cheaper than other statin medicines.

OpenGL is a standard API that is used to manage 3D graphics on desktop computers. Although OpenGL is independent of customized hardware it?s not suitable for all kinds of devices. Therefore both OpenGL ES andWebGL was created. These can be viewed as subsets of OpenGL.

Stock analysts have through the analyses they write a large impact on the expectations on the market and the direction of investors investments. This creates undesired fluctuations on the market that raises the level of uncertainty. The way that the analysts satisfy their need for information is connected to how their final analysis will be shaped. There is a large knowledge gap concerning the way that the analysts work and this gives unsatisfactory ways of communication. This thesis is set out to create a greater understanding of how optimal communication towards this target group should be brought out.
