In Sweden the climate makes it impossible to feed fresh herbage to cattle during many months of the year. During periods when preserved forage must be supplied it is important that this forage is stored in such a way that high quality is retained, both nutritionally and hygienically. Furthermore, it is essential that losses occurring when handling and storing the forage are kept as low as possible. This study compares storage in tower silos, bunker silos, big bags and bales,estimating dry matter losses as well as losses in metabolizable energy and crude protein that occur during storage. The results show that tower silos, bunker silos and big bags, the systems with the largest amount of forage and a long feed out period involve larger losses than bales, which are fed out immediately after being opened. As the feed out rate influences the losses, tower silos and bunker silos should be used during the period of the year when the feed out rate is as high as possible, i.e.

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.

Peat litter is a soft material with high absorbency. About hundred years ago many farmers in Sweden used peat litter to their dairy cows. After the World War II the use of peat litter decreased and the farmers used more straw. Nowadays (year 2007), when it is harder to find straw and sawdust to buy, peat litter is advancing again. The purpose with this study is to investigate peat as a litter to dairy cows.

This degree project documents the meeting of four high-school students with working life before and during the practical training period, which is a mandatory part of the Swedish media curriculum. We looked into practical training, which we qualify as the crossroads between school and working life, from a student?s perspective. We chose to approach the problem theoretically via hermeneutics and we used the case study method for our field research. The foundation of our pre-understanding of the media curriculum?s practical training period lays on previously published research, the study of specialist literature, own experience gained during practical training and teaching experience at high-schools as well as a pre-study we carried out.

To increase the understanding of how individuals total life situation affects their stress level and health has lately more frequently been discussed in different contexts. Furthermore, it is important to have knowledge of power structures that exist under given circumstances in a society to get an increased understanding of how to structure the health promoting work to get the highest possible benefits. People?s work life is essential to their health, since we spend a lot of time at work. The aim of this study was to find out which factors that relate to nursing staff?s health and stress level from a general perspective.

In this Bachelor Thesis (20 p.), we present the history and development of "Intelligent Houses", and most important- explore some of the future possibilities in this area. The project has been carried out through an interdisciplinary cooperation between three different educations at the Blekinge Institute of Technology. By conducting a dialogue with various actors with different professions, we have been trying to identify needs within the concept of "Intelligent Houses", were the end user is not only the tenant or homeowner. Through Participatory Design methods, such as a Future Workshop, we have brought the users together to discuss their own and each others needs and hindrances in their respective work practice, and how intelligent house technology could improve their work conditions. We have also been testing a highly sophisticated CO/CO2/Moisture/Temperature/Enthalpy multi-sensor & controller, originally developed for regulating indoor climate systems. Based on the needs we have found in our fieldwork, we have been looking at possibilities to make multi user solutions with the sensor..

This thesis is made by Carl Persson and Alejandro Saavedra for Gryaab. Gryaab is Gothenburg?s water processing plant and produces about 60 GWh biogas annually with a flow around 1150 Nm3/h. Gryaab wants to research their possibilities to become independent with electrical energy and the possibilities to enrich, upgrade biogas. The use of methane rich gases like biogas and natural gas is today low in Sweden compared to major parts of the world.

Purpose: The study examines the risk a rising from the acquisition of shares, and its relation to the expected return. We would like to see how a high-risk portfolio is related to a low-risk portfolio. Although studying the portfolios annual performance.Theory: The theories that have been used in the study are, Capital asset pricing model, CAPM and portfolio theory.Method: The study is based on a quantitative method, the time interval is from 2008 to 2010.The annual reports, historical stock prices for companies and the index are used to perform calculations based on the essay theories.Conclusion: The beta value has positive liner correlation with the expected return. When there are bad times in the world, the companies are negatively affected regardless of industry. The Portfolios developed in the same direction during the time period..

Abstract In high voltage substations there is an increasing demand for computerized equipment, and automation of operation and supervision. The future primary equipment will provide the possibility to collect more information and to provide better control for improved effectiveness. Since ABB has got a large customer target, each product must be custom made to fulfil the customers (often from different countries) demands. Later these products will be configured by engineers who may not be familiar with the tools used at ABB. This is a very expensive and time consuming.

The aim of this master thesis is to examine high school students? understandings and experiences of gender equality and to critically study the formulations and the basis of the project from Save the Children Sweden which are the basis for this master thesis. By using critical discourse analysis and gender theories the formulations and basis of the project and the interviews has been analyzed. The analysis of the project showed neglect for intersectional perspectives and taken for granted hidden opinions about masculinities and femininities. The interviews have been conducted with four high school students, and the students felt that they attend schools which are equal between genders.

A sample of milk inoculated with S. aureus was treated with penicillin, and Antipen (a new commercial product containing penicillinase) was added. To another sample with S. aureus and penicillin, formic acid to pH 5 was added, and to yet another sample, a combination of formic acid and Antipen was added. Controls with no penicillin were treated in the same way.

The aim of the present study was to investigate response time variations in tasks for assessment of high level language functions and how response time is related to education, age and gender. Response time is defined as the time to complete a task after it has been presented. 103 subjects, aged 20 to 80 years, were tested with the Assessment of Subtle Language Disorders, Sentence analysis and Morphological completion. The subtest Comprehension of ambiguous sentences showed the longest response time and Morphological completion the shortest. Correlations were found between increasing age and longer response time for Comprehension of metaphors and between education and response time for several subtests.

The main purpose of this study is to examine if variations in voter turnout for the European Parliament elections in each member state is affected by the rate of national party polarization on the EU-dimension of party politics. The theoretical background assumes that a high level of polarization generates higher voter turnout since more alternatives are presented to the electorate. This makes it easier for the electorate to find a party that represents their preferences. This will, in turn, increase the likelihood that they will participate in the election.This study uses a research design based on a quantitative analysis with data from each member state, except those with compulsory voting, in the European Parliament elections of 2004 and 2009. The results of the analysis indicate a relationship between high levels of party polarization and lower turnout in the European Parliament election.
