Background: As a part of a national health control program, Statens VeterinärmedicinskaAnstalt performs diagnostics to screen flocks for certain pathogens causing high mortality,morbidity and/or serious economical losses. There are several viruses in the programincluding IBDV (infectious bursal disease virus), IBV (infectious bronchitis virus) and NDV(Newcastle disease virus). Method: 96 serum samples were collected from different poultryflocks in Sweden and analyzed by ELISA, which are currently used in the health controlprogram as well as by a commercial prototype of a multiplex immunoassay manufactured byLuminex Corp., which is currently under evaluation at the United States Department ofAgriculture USDA. This 4-plex assay detects antibodies for the three above-mentionedviruses as well as antibodies of avian reovirus. In the context of this study the ELISAs run inroutine diagnostics as well as a REO ELISA were used as the standard for comparison.Result: The antibody concentration in serum from vaccinated chickens was high while theantibody concentration level in serum from not vaccinated chickens was low.

The purpose of this thesis is to examine whether the teacher's background affect students' approach to mathematics teaching. Characteristically, in Sweden today is that mathematics is perceived as difficult subject and that the number of foreign teachers has increased. The study examines a phenomenon which the relationship between the teacher's language accent and substance difficulties.The method used for data collection is questionnaires, in order to investigate the phenomenon as the relationship between the teacher's accent and substance difficulties.The investigation has been carried out based on the students' point of view, both secondary and primary school pupils. What difficulties have arisen in teaching?  What is the biggest obstacle to achieve the goals of mathematics, to understand the teacher's language accent first in order to understand the subject, or that mathematics is difficult in itself to be understood as a substance.The result clearly shows that the teacher's accent does not affect teaching and students' view of mathematics as a subject.

This thesis has been carried out within the bachelor program for mechanical engineering at Karlstad University in collaboration with BAE Systems in Karlskoga. The purpose with this work was to design a mechanism and associated parts for loading and unloading of shots between primary and secondary magazine in BAE's new 40mm's ship gun.Parts designed or redesigned among other things a transfer mechanism for shot at loading and unloading, well as a hatch mechanism which makes the shots do not fall out of the primary magazine when making separate use. Various important details have been designed to maintain a good functionality of the mechanism.The construction work has mainly been carried out in the CAD software Solid Edge and its associated FEM module. The construction work has also been carried out on rough calculations for constructed details in order to ensure that they meet the stringent requirements of military use in tough marine environment. Two of the most critical parts of the structure where analyzed with the FEM module for estimating the stresses in the material at the applied load.The final design, which is a result of the thesis, meets the requirement specification and the set targets.

The habits of living are seen as important factors for public health, and are related to the primary socialization. Exercise and food habits are two main factors for development of health or ill health and are both related to the overweight epidemic. The overweight increase among children and youth has been given particular attention. The aim of this study is to examine how 15 year olds Body Mass Index, food- and exercise habits are connected to each other and also how they are related to socialization. The study is a cross sectional survey among 208 pupils in ninth grade, Kristianstad.

The metal mining history goes thousands of years back. The downside of the mining industry is the large amount of tailings created during the mining operations. Drainage and leaching of heavy metals from these tailings may cause major environmental problems including acid mine drainage and leaching of heavy metals. This study examines a pond located near an old mining site, where part of the old mining facility has been recently (1990) restored. The objective was to assess eventual metal contamination from historical mining and the recently performed restoration using a sediment core as a natural archive of historical metal inputs to the pond.

This study is about what teachers in primary schools say that they are doing to create a school for all.The purpose of this study is to find out what teachers in primary schools say that they do on their mission to create a school for everyone and how they organize teaching to achieve this. The study was conducted as an interview of five teachers from elementary school of different gender and with a qualitative method because it provides a great opportunity to problematize, interpret and understand the responses of the interviewees.The results show that all the teachers think that their mission is to teach so that they can give each student what they need to achieve the goals. This may not be every day but over time, they hope that all students feel that they get so much of the teacher's time that they need..

The aim of this study was to examine the amounts of heavy metals in the sediment of a wetland constructed for stormwater treatment. The wetland is called Vattenparken and is located in the city of Enköping. The heavy metals which were analysed were Pb, Cd, Ni, Zn, Cu, Cr and Hg. The total metal concentrations were determined using HNO3 chemical extraction. From 8 sampling sites 5 sediment cores were taken.

Flowcytometric technology has been widely used for measurement of the absolute numbers of T-lymphocytes subsets in Human Immunodeficiency virus (HIV), defining the disease state, monitoring antiviral treatment, and identifying any risk for opportunistic infections. A manual preparing of the samples is required. More recently an automated and enclosed blood cell counting, Celldyn Sapphire has been introduced. In this study the performance of the Flow cytometer EPICS XL as a reference method for analysis of CD3+, CD4+ and CD8 T-lymphocytes was evaluated with blood from 40 individual?s samples.

April 28th 2010 the Swedish parliament decided that the combined teacher exam will be divided into four parts. This means that the education for preschool teachers and primary school teachers will have to be separated and future teachers will have to decide before their studies what ages they want to work with. To investigate if this could affect the quality of the choice I have interviewed 5 new teachers from the combined teachers program about what ages they wanted to teach before they began to study and what ages they wanted to teach after completed studies. I did this to see whether the choice was influenced by the educations or not. It turned out that all 5 had an idea of what ages they wanted to teach in before they began the educations and only one of my interviewees changed her mind during the studies.

Introduction: Sleep is necessary for human survival. Difficulty sleeping occurs in about one in four adult person in Sweden, insomnia in every ten. There are several reasons for difficulty sleeping, where stress is one of the most common. The quality of life and health are affected negatively.
