Scrapie is an infectious neurologic disease in sheep caused by prions, corresponding to transmissible spongiform encephalopathies (TSEs) in other species. The prion is presumably constituted of PrPSc, the misfolded form of the normal endogenous prion protein, PrPC, which is found in practically all cells in the body. PrPSc can induce a conformational change in PrPC and misfold it as an imprint of itself; this is how prions amplify and spread. The process of conformational change is poorly understood and there might exist intermediate forms between PrPC and PrPSc. Bioassay using mice has traditionally been the golden standard in prion studies but is limited by cost and time.

ABSTRACT: Commercial swab transport systems are used for collection and transporting of fecal and other microbiological samples. This system must maintain viability and contribute to survival of microorganisms during transport to the laboratory. Four swab transport systems have been compared, eSwab, ?- Transwab and fecalSwab, all three with flocked swabs, and Copan Venturi Transystem with rayon swabs. The study followed the recommendations from the Clinical Laboratory Standard Institute; document M40-A for recovery of Samonella, Shigella, Yersinia and Neisseria gonorrhoeae after storage for 0, 6, 24, 48 and 72 h at room- (22-25°C) and refrigerated (2-8ºC) temperature.

Non-contact anterior cruciate ligament (ACL) injuries is a serius and traumatic injury to the knee that is common in female soccer players and often force the player to quit or lower the level of activity because of lost stability in the knee or from fear to suffer  a new injury. Female soccerplayers have a higher risk than their male counterparts to get an ACL rupture and especially adolescent females have a high risk. The most common causes to a non-contact ACL rupture is side-cutting manuvers and landing after jumping. Every other player with an ACL rupture develops osteoarthritis within 10-15 years from the time of injuryResults: The higher risk for females to incur a ACL rupture is due to smaller intercondylar notch, they?re in the follicular or ovulatory phase of their menstrual cycle, increased knee laxity, dominance in the quadriceps muscles, flexion in hip and valgus movement in the knee.

The Goal with this Master of Science thesis is to expand the possible turbine efficiencymeasurements on an exhaust turbocharger. It was done as a part of the CICERO competencecentre. To feed the turbine with air a special flow rig has been used. Instead of loading theturbine by just restricting the compressor flow a docking system for an electrical dynamometer isdesigned to use the dynamometer as an additional loading source. By using an electricaldynamometer as loading device for the turbine, measurements are not depending on compressorperformance.A large part of the work consists in designing accessories for the dynamometer.

Abstract:Ambulance nurses have in their everyday work a varied work environment, the pace of work can quickly shift from being calm and structured to be a severe acute situation.Objective: The aim of the study was to describe how professional nurses in the ambulance operations experience their physical and mental work environment in daily practice.Method: A qualitative interview study with semi structured questions was used. The study group consisted of two women and three men, ages between 27?42 years. The study was carried out on an ambulance station in central Sweden. Based on collected data, a qualitativecontent analysis was performed that resulted in three categories.Results: The result showed that the ambulance nurses regarded that it was a lot of heavy lifting.

Hypotyreoidism är en vanlig endokrin sjukdom hos hundar. Den orsakar nedsatt livskvalitet i form av utbredda symptom från flera olika organsystem och sjukdomen kräver livslång medicinering. En orsak till hypotyreoidism är Canine Lymphocytic Thyroiditis (CLT), en autoimmun sjukdom som står för ett stort antal av sjukdomsfallen hos hund. Mycket talar för att utvecklandet av sjukdomen har en ärftlighetskomponent eftersom den uppträder i mycket hög frekvens inom vissa raser medan det är en tämligen ovanlig åkomma inom andra raser. Studier av hundpopulationer har visat på en genetisk koppling mellan CLT och gener för Dog Leukocyte Antigen II (DLA II) hos vissa raser.

Chemicals in preschools - a study of endocrine disrupting chemicals and awareness among preschool teachers The purpose of this study was to investigate endocrine disrupting chemicals that have been shown in preschools and also the preschool teachers? awareness of these chemicals. There were two methods used for completing this study; a literature study and a practical study. The literature study was made by researching on the internet and in books. The practical study was performed by sending questionnaires to all preschools in Kiruna municipality to study awareness among staff.

Around 30,000 people in Sweden suffer stroke every year, out of which about 12,000 end up with language difficulties, aphasia. Behind every person with aphasia there are significant others whose lives are also affected. Studies of how aphasia affects the health of these people are few. The overall aim of the present study was to examine how significant others of people with aphasia perceive their life situation, and how their quality of life is affected by the illness of their partner. Spouses of people with aphasia were contacted through aphasia groups and the Swedish Aphasia Association.

In this paper we examine what security is to the individual and how the individual creates and maintains security in their work. The purpose of this paper is to study how the creating of security in working life is performed. We conduct six semi-structured qualitative interviews with permanent employees in the private sector and we encode our material using thematic analysis. We analyze our material and illustrate our problem area on the basis of Anthony Giddens's theory of ontological security and give examples of how security and creating of security is performed at the empirical field with previous studies in the research area. Our survey shows that security for the individual at work seems to be about having continuity in everyday life, financial stability, a permanent employment, a challenging and fun job and a family in good health and good living.

In this essay we have been trying to get an understanding of what Swedish charter tourists cares for when they are going on vacation. The Tourism industry is a major field with a lot of winners, but it also comes with consequences. The purpose with this essay is to get an understanding of how aware the Swedish charter tourists is of these consequences. We would also like to get a perception of how the tourists themselves believe that their presence effects the locals at the destinations they are visiting (if they assume that they are). There are several different types of consequences that can appear in the context of tourism, but we have decided to focus on one kind.

This paper is a literature review that examines how good mental calculation skills benefit pupils, which could work as a valuable learning tool for future teachers. The study addresses four key questions: ?What are the advantages of proficient mental calculations??, ?What strategies exist for mental calculation skills??, ?How can teachers accommodate their teaching to develop pupils? mental calculation skills?? and ?What has arithmetic looked like in different eras and what algorithms have been used??. Through literature searches in search engines, scientific articles were found, which formed the basis for the result segment. This was divided into two parts: A historical and a didactic overview.

I want to investigate different preschool teachers' views of their daily work in terms of the diversity of children and learning, and the methods and strategies of preschool teachers use in their everyday lives, to meet every child's individual needs. I also want to investigate preschool teacher?s perceptions of children's social skills as this is included in the pre-school assignments relating to a favorable social environment for all children.To find this out, I have compiled three issues.What are the views interviewed preschool teachers to learning and different lustful methods that make the educational activities meaningful for all children?? What pedagogical strategies do preschool teachers to respond to the diversity of children?? What opinions have interviewed preschool teachers about children's social interaction with other children in preschool?The conclusion is:all children are different and learn in different ways. Teachers have the responsibility to ensure every child's development and adapt the business to the children's level and needs in a way that could inspire children to learn new skills. It is teachers' responsibility to provide children with good opportunities to express their views and feelings.

The following study explores the relation between psychosocial work environment and individual health. The purpose is to examine how female employees in the occupational health sector experience their own psychosocial work environment, focusing on different influencing factors in both the workplace and their private life regarding the employees own health. The study applies a hermeneutic approach in which qualitative interviews constitute the empirical data. Previous research on this particular subject has focused on the following themes: the combination of work-family life, demand/control model and flexibility in the workplace in relation to health and stress. The theoretical framework used in this study integrates relevant concepts, specifically SOC, poor leadership and flexibility.

Identity includes an individual´s self-image and the consciousness about their self. It is about being the same person despite changes in their life situation. The identity often get´s fragile because of the disease. Beacuse of the individual´s feeling of lost identity there may arise a conflict between the person and people in his or her surroundings. They may no longer see the sick person in the same way as they used to.

In two feeding experiments Bacillus induced priming of plant defense was tested for its effect against the generalist insect pest Spodoptera littoralis. The main hypothesis for the study was that Bacillus induced priming would enable the plant Arabidopsis thaliana to defend itself better against this insect herbivore since this priming seems to involve jasmonic acid, known to be important for plant defense to insects. A secondary objective of the study was to examine if any differences in a primed defense capability could be seen between different natural genetic variants (ecotypes) of A. thaliana reflecting habitat differences in pest pressure. The methods used for plant cultivation and Bacillus inoculation were aimed at reflecting conditions that can be expected in an agricultural cropping system. This meant that all plants were cultivated in soil, and the feeding experiments were conducted with the plants growing intact in the soil system.
