Within agriculture it is important to optimize the use of nitrogen, not only from an economic point of view but also to minimize damage to the environment. This can sometimes be difficult, especially within organic farming. Organic farmers are using increasing amounts of waste products from the food industry to cover their nitrogen needs. These different organic fertilizers release nitrogen at different rates and under specific soil conditions. Because of this, it would be beneficial to have a standardized method to measure the amount and rate of nitrogen mineralization from organic fertilizers. This project contributes to this knowledge by investigating whether relatively simple and repeatable laboratory methods can be used to estimate the nitrogen fertilizer value of organic fertilizers.

Dampness in the indoor environment have been a major issue of discussion the last decades since more and more people complain about their indoor environment. In the present situation there are difficulties to find what causes people?s discomfort in a damp environment even though there is a strong connection between dampness and human health.The aim of the thesis was to contribute to the work done today to achieve a better indoor environment in damp buildings. The purpose of the work was to evaluate whether the measures issued for dampness in the indoor environment contributes to the improvement of health and environment for those who are living or working in that space. Through a literature review, interview and survey the following three questions were answered to achieve the aim and purpose:How are people affected by the indoor environment in damp buildings?Which are the measures issued to prevent dampness in the indoor environment?Do these interventions contribute to a better indoor environment?How people are affected by the indoor environment in damp buildings and how these problems are prevented were the foundation for the continued work with the survey.

Syfte och frågeställningarSyftet med den här studien var att undersöka den aeroba fysiska aktivitetsnivån hos gymnasieungdomar på Bygg- och anläggningsprogrammet under skoldagar som innehöll teorilektioner, praktiska lektioner, idrottslektioner och raster. Frågan som ställdes var: Hur ser den fysiska aktivitetsnivån ut under teorilektioner, praktiska lektioner och lektioner i idrott och hälsa samt under raster hos gymnasieelever på Bygg- och anläggningsprogrammet.MetodI studien deltog 9 pojkar i åldern 16 år, längd 174-192cm och vikt 51-91kg. Den test som genomförts är 5 Minuters Pyramid Test (5MPT) och registrering av aerob fysisk belastning gjordes med hjärtfrekvensmätningar. 5MPT är ett skytteltest som är fem minuter långt, där försökspersonen tar sig fram och tillbaka mellan två stolpar och så snabbt som möjligt passerarfram och tillbaka över en vertikal pyramidformad trappramp (sträcka 5,5 meter). Antalet vändor, skattad ansträngning samt hjärtfrekvens (HF) registrerades.

This report discusses a method to detect divers in harbour environments usingpassive acoustic detection. The goal was to achieve as high detection as possiblewithout having too high false alarm rate. A short execution time was also desirable.By using the characteristic of an inhalation a band-pass filter was applied to the signalto improve the signal to noise ratio. After the filtering an energy estimation of thesignal was made. This energy estimation was later used in a frequency analysis, whichcould tell us if there were enough energy in the frequencies that correspond to adivers breathing frequency.

To establish good horse welfare there are several factors that need to be considered. One important factor is the environment in which the horses are kept. In Sweden horses are stabled during long periods of time in the cold season and consequently the stable environment is even more important. The most essential environmental factors in a horse stable are ambient temperature, relative humidity (RH) and concentrations of contaminants in the stable air. The air in a horse stable contains dust, noxious gases, moulds and microorganisms which all can contribute to developing respiratory diseases in horses.

This paper studies the option market?s implied dividend as a predictor of future equity market returns. We introduce this variable in the simple total return framework and discuss some complications of using it as a proxy for the expected dividend. We construct some regressions using the price-dividend ratio and the implied dividend growth, and test them on six years worth of data on the EURO STOXX 50-index. The main result is that implied dividend growth exhibits some forecastability over two-year horizons, but that the dataset is too short to draw any definitive conclusions about long-horizon forecastability.

This thesis examines the presence of threats and violence directed towards animal welfare inspectors/ officers. The main tool is a survey regarding threats and violence directed at animal welfare inspectors/officers. The questionnaire was distributed to animal welfare inspectors/ officers who worked on 15 of the country's 21 provincial governments. The response rate of the survey was 68.9 percent. The main conclusion of the study is that threats and violence directed at animal welfare inspectors/ officers are common.

This literature review summarizes available data on infection with the parasitic roundworm, Ascaridia galli, as a cause of disease in poultry, including the consequences of a conversion to alternative production systems. Ascaridia galli has a direct life cycle with resistant eggs that survive and are easily spread in the environment, especially in systems with bedding materials where the faecal contact is high. The infection is usually subclinical but depending on the infection dose, the symptoms range from weight loss and diarrhea to mortality. Factors such as the feed composition and genetic variation among different hybrids clearly affect the establishment rate of the infection. Ascaridia galli will probably become an increasing problem, with a shift from the traditional battery cages to alternative systems where the risk of re-infection is high.

The aim of my study is to critically analyse the discourse behind two different integration projects in Sweden, by using post colonial theory. My hypothesis is that many projects intended for increased integration includes a view of immigrants as the ?Others? which can be seen in how one talks about integration and culture in the discourse behind integration projects.The first of these two projects aims at increased diversity in the cultural sphere, organized on at state level. The purpose of the second project is to increase the communication and results for schools in areas with a high rate of immigrants in Malmö. In my study I make a discourse analysis of the discourse behind these two projects and study how they are motivated and how one conceptualise culture and integration in these documents.

This thesis aims to analyse a time series containing the annual accumulation rate of minerogenic matter in the lake Kassjo?n. First there is a theoretical survey of some frequently used tools for the analysis of time series in the time domain and in the frequency domain. This survey is followed by a simulation study that illustrates how the theoretical tools work in practice. After this, the time series "toolbox" is used to analyse the time series from Kassjo?n (5701 data points).

The purpose of this study is to describe melanotic tumours and the pathogenesis of these tumours. The focus of this study is on differences between benign and malignant tumours as well as the prognosis one may expect when diagnosing this disease. The mechanisms responsible for the occurrences of the tumours are not yet fully understood. It is believed that factors such as chronic trauma, infections, medications and hormones affect the cell mechanisms in some way. Determinants of the malignancy of the tumour are not completely known.

BakgrundVårdrelaterade infektioner (VRI) har funnits lika länge som patienter har vårdats. Redan på 1800-talet steg läkaren Ignaz Semmelweis fram och förespråkade för att skrubba händerna med klorid i syfte att förhindra spridning av bakterier från obduktionsbordet till förlossningsavdelningar. Trots den tidiga kunskapen om god handhygien drabbas patienter världen över av VRI. I Sverige under våren 2012 drabbades 8,9 % av alla somatiskt sjuka patienter som vårdades på något sjukhus av en VRI. Syftet med litteraturstudien har varit att beskriva åtgärder för att förebygga uppkomsten av vårdrelaterade infektioner.MetodEn allmän litteraturstudie baserad på Forsberg och Wengström (2008) har genomförts.

This report discusses developing a software log tool for analysis of industrial processes. The target was to develop software that can help electro Engineers for monitor and fault finding in industrial processes. The tool is called PLS (Process log server), and is developed in Visual Studio.NET Framework 2005. PLS works as a client with Beijer Electronics OPC Server. The program is able to read data from PLC (Programmable Logic Controller), trough the OPC Server.

This essay examines how high school teachers in physical education and health thinks about assessment and grading. The essay show how teachers assess pupils during lessons and how teachers grade their students. The survey was based on interviews, in which six different teachers answered questions on the topic of assessment and grading. The issues surrounding assessment was linked to the theoretical concepts of formative and summative assessment, to see if the assessment methods teachers use. The issues surrounding grading was related to the theoretical concepts of validity and reliability in order to see how similar the grading is.The essay provides a picture of how the assessment and rate again looks different teachers.
