A growing population together with a change in food habits to a more diverse diet containing more animal products such as meat and milk makes the possibility to produce and sell products of cattle a growing market. And at the same time there is an ongoing debate about global warming, where raising cattle is questioned due to their high production of enteric methane. To be able to raise animals in a more environmental friendly way and at the same time improve productivity in a developing country such as Vietnam would be favorable. The use of feed additives with high electron affinity could decrease the methane production and at the same time improve the gross energy digested. Nitrate and Sulfur are both good electron acceptors, but due to its toxic effects the use of nitrate in feed has been neglected.

Syfte: Syftet med denna studie är att undersöka om en högre risk ger en fondsparare i PPM högre avkastning vid ett långsiktigt fondsparande och om den avkastningen speglar den risk spararen tar.Metod: En kvantitativ studie som är baserad på sekundärdata, som är inhämtad från Morningstar. 60 pensionsfonder analyseras från tre olika riskkategorier, med en mätperiod på 10 år. Frågeställningarna har besvarats med hjälp av relevanta teorier, hypotesprövning och korrelationsanalys.Slutsats: Efter att ha undersökt dessa PPM-fonder så kan man väl konstatera att en högre risk ger en högre avkastning. Däremot speglar inte avkastningen ökningen i risk, förvisso har högriskfonderna bäst sharpkvot men lågrisk fonderna har bättre än medelriskfonderna, vilket betyder att vi inte kan säga att avkastningen i förhållande till risken blir lika bra eller bättre för att du ökar ditt risktagande..

ABSTRACTOverweight and obesity is an increasing problem worldwide although high-income countries take a leed. High BMI during pregnancy and delivery constitute to many risks for both the mother and her outcome. Intervention programmes with the purpose to get the pregnant women to eat healthier and to excercise more are now working out in many different shapes. The effect of these activities varies. The aim of this study was to investigate if interventions during pregnancy, with women who?s BMI are 25 or more, affects health of the mother and her expected child, delivery outcome and self estimated health.

This report is a risk- and vulnerability analysis of how the commercial ship and its goods can be a threat to the environement and to human health in case of a discharge. It present the most common dangerous goods that are transported with ship through Kattegat in the Baltic Sea..

Uppsatsen handlar om användningen av pedagogisk dokumentation i förskolan. Vi har problematiserat dess betydelse för relationen mellan förskollärare och föräldrar. Syftet med uppsatsen är därför att undersöka pedagogisk dokumentation i förskolan och dess betydelse för föräldrasamarbete. Vi vill genom vår undersökning studera hur förskollärare använder pedagogisk dokumentation i relation till föräldrar samt hur föräldrar upplever den dokumentation de tar del av.Dagens förståelse av pedagogisk dokumentation i förskolan placerar vi i ett sammanhang genom att beskriva dokumentationens rötter i utvecklingspsykologiska observationer. Vi presenterar Reggio Emilia som en inspirationskälla till dagens dokumentationsarbete samt presenterar portfolio som ett arbetssätt.

The city of Uppsala and its surroundings are a very expansive area. A prerequisite for a sustainable development of the area is well-functioning supply of drinking water. In Uppsala municipality, the Uppsala esker and Vattholma esker are the groundwater storages for drinking water. Besides the eskers, other sources of qualitative groundwater in the Uppsala municipality are relatively poor and more than half of the area consists of ground conditions with a risk of saline groundwater. The neighbourhood of Vreta-Ytternäs is situated 10 km south of Uppsala, in the area with risk of saline groundwater but outside the municipal water supply.

Background: Urinary tract infections caused by indwelling urinary catheters causes unneccesay suffering among those it affects. These infections are also financially straining on the health care services. It is therefore of importance to gain knowledge about which evidence based preventive interventions that have the possibility to reduce the risk for bacteriuria and urinary tract infections among patients with indwelling urinary catheters. Aim: This study aimed to compile available knowledge concerning i) if silver alloy catheters does reduce bacteriuria in this patient group, ii) if aseptic catheterization does reduce bacteriuria in this patientgroup, iii) which routines for changing the urinary drainage bag reduces the risk of bacteriuria, iv) which routine genital hygenic care reduces the risk of bacteriuria? Method: Litterature was searched for in the data bases Cinahl, Medline and The Cochrane Library using the data bases? thesaurius combined with OR/AND.

This thesis describes and examines a new line of business, CleanTech. CleanTech comprises a wide range of different types of companies and is not yet well defined. In this thesis only the Swedish market is considered, and a variety of players on the market are included to give the most extensive picture of the current situation. Recent research shows that a gap has arisen between governmental financing and private equity-investments in CleanTech-companies. This gap occurs mainly in companies in expansive phases and causes problems both for the companies and for the line of business as a whole. To investigate this gap the Swedish CleanTech-business is described in terms of earlier and existing financing, age and size of the companies and their turnover and profit.

The bachelor's thesis is to examine the explanatory factors affecting the choice of capital structure in real estate companies. The analysis is based on data collected from the main financial reporting from 2007; all listed real estate companies listed on Swedish, Norwegian, Danish and Finnish stock market. Based on previous research and theories, we have defined five independent variables that are linked to the debt ratio, which are: profitability, growth, firm size, cost of debt and operational risk. The statistical tests have resulted in that we can say with certainty that profitable firms tend to have a lower debt to equity ratio. We can also say with certainty that property companies with high interest costs have a high level of indebtedness..

In the process laboratory of Metso minerals (Sala) AB, continuous tests have been made with a laboratory unit High-Rate thickener. The tests are made in order to compare three methods of thickening techniques of suspended solids. The three techniques are High-Rate thickening, conventional thickening and lamella thickening. The High-Rate and the conventional trials are based on a continuous method, while the lamella thickener is based on batch trials. Because the lamella thickener is based on batch trials and there were some optimization problems with the adding point of the flocculant at the continuous trials, it was not feasible to compare the lamella thickener with the other two thickener types.

This master thesis is developed based on the desire of the water and sewage department in the municipality of Karlskrona. The department, which vouches for the quality of produced drinking water and sewage cleaning, was in need of help dealing with risk analysis.The water and sewage department is obliged to identify and assess risks according to Swedish legislation. However, no guides for this purpose regarding safety, health, environment and quality were available. The aim of this report was to accomplish a guideline for the performance of risk analysis within water and sewage plants. If the guideline is used, the requirements in the legislation will be obtained.

The purpose of this study was to review a group of youths in a municipality which all had committed criminal acts. The study is based on 66 youths between the ages of 13 and 20 that were all matters for the social services. The social inquiries of the youths where reviewed using a quantitative method. Their backgrounds where examined to identify what type of risk factors they had and what type of crimes they had committed with an aim to detect if there were a relationship between the risk factors and the art of the crime. The result of the study showed that the majority had committed crimes against another person and the risk factors included family related factors and school problems.

A major issue that has been a subject for quite some time is whether there will be a scarcity of metals in the bedrock in the future and whether or not we might end up with a problem similar to that of the big oil crisis in the mid-seventies. Following the oil crisis many oil companies started up with risk management to control future risks. This work presents how Swedish mining companies work with risk management to handle risks that might come up in the future due to metal scarceness. How Swedish mining companies look at the possible metal scarceness and if they use risk management in their decision-making process is studied. By doing interviews with Swedish owned mining companies it was found that the mining companies did not see the future metal scarcity as a risk, even though 2/3 of the companies acknowledged the scarceness to be a reality.

Purpose: The purpose of this thesis is to clarify and evaluate the concept of scenario planning.Methodology: Our research methodology has a qualitative approach and uses deductive reasoning.
