We set out to compare two different categories of workers: the, so called, white- and blue collar workers. The studies aim was to measure if there were any observable differences between the two in means of optimism and sense of coherence. There are two tools created for measuring optimism and sense of coherence, the Life Orientation Test ? Revised (LOT-R) measures an individual?s level of optimism and Aaron Antonovsky devised a test for measuring an individual?s level of sense of coherence (SOC). Optimism is best explained like a way to measure anticipation, how an individual expect future events to fall out.

Compressed air is an energy source that is widely used in today's trucks and buses.Compressor located next to the engine supplies the pneumatic system with the compressed air and is lubricated with the engine oil. Some of the oil follows the air flow in both liquid and solid phase. The solid phase, namely the carbon particles are created due to the high temperature in the compression chamber.Oil- and particles carryover softens and destroys the rubber material in the air valves and disturbs the mechanical function of various components in the pneumatic system. In order to reduce oil- and particles carryover is an Air Processing System (APS) set downstream the compressor.No method for establishment of oil- and particles carryover from the compressor exists at the moment. Therefore the filtration efficiency of APS is currently unknown.

Does a person´s self esteem contribute in the process of creating false memories? Previous studies show that mood is related to false memories as well as to self esteem. This led to the focus of this study, to examine the relationship between false memory and self esteem. The question is examined by comparing the amount of false memories produced in the Deese-Roediger-McDermott (DRM) procedure with people´s scores on Rosenberg´s self-esteem scale. 59 people participated in a test with three different elements, a self esteem test and a memory test with both recollection and free recall.

This thesis has been carried out in collaboration with two students at the Department of Dental Medicine at Karolinska Institutet in Stockholm, Sweden. The aim of this project was to construct a computerized decision support system to facilitate diagnosis of changes in the Oral Mucosa using information collected by the above mentioned students. A program which poses specic questions to the user was constructed with the Java programming language. Depending on how these questions were answered, one or more possible diagnoses were presented by the program. In order to conclude whether or not this program was of any use in terms of time savings, a series of tests were run and timed both when using the program and when not.

The aim of this study is to examine the patient's understanding of the counselling while testing for an STI. The method was an inquiry directed to patients at two receptions, where tests for STI are made, and on the Internet for patients who made a test within the last year. The study involves 95 participants, 39 answered the inquiry directly after the test. The main results show that most participants are positive to talk about their sexuality and sexual strategies with the personnel, irrespective of who takes the initiative to the counselling. Women are yet more negative then men to talk about their sexuality, even if the test is made voluntarily by the woman.

This essay examines if formative assessment causes any impact on upper secondary school students results in social science. Other questions asked are which group of students benefits most from formative assessment and if any connections can be found between the students result and their cognitive approach to learning, problem solving capability and attitude to school.Two classes from a school in Stockholm were chosen to participate in the study. The theoretical framework is mostly based on former research performed by Black and William (1998, 2003). Multiple methods were used, including an experiment with a parallel-group design with two groups, a survey and a problem solving test. Statistics is used to describe and analyze collected data.Both groups were taught during five lessons in the same field of knowledge with the same kind of teaching, apart from formative assessment.

In this Master thesis, microwave connections between circuit boards are constructed. The primary frequency band is the X-band (8-12 GHz). The purpose of the connections is to enable a more simple and cheaper way of mounting the circuit boards inside a container. The connections have been designed and evaluated, using different computer programs. A few prototypes have been built and measured.

This master's theses was carried out on assignment from Stockholm Vatten AB as a part of a project developing new waste water treatment techniques. The goal of the theisis has been to evaluate an anaerobic membrane bioreactor for treatment of waste water from Hammarby Sjöstad. The bioreactor has not been heated and the main interest has been to study the gas production, power consumption and the reduction of organic matter and nutrients.The system has been completed with a reverse osmosis unit and a total of four batch runs have been made with good results. The use of reverse osmosis allows nutrient in the waste water to be reintroduced into circulation as the reverse osmosis concentrate can be used as crop nutrient.The membrane unit is of VSEP ("Vibratory Shear Enhanced Processing") type and an extensive membrane test has been conducted. This so called L-test helped determine the most suitable type of membrane for the system to allow a higher ±ux and thus lower power consumption.

The purpose of this thesis is to research public librarians view ofthe public library as a meeting place and how it may contribute tofacilitate social integration. To study this we have asked thefollowing research questions: How do public librarians work withthe public library as a meeting place? And how do they contributeconditions for ?soft inclusion??The method we have used for this study is semi-structuredinterviews. Seven public librarians from the Gothenburg areawere interviewed and the empirical material was analyzed usingqualitative content analysis.As a theoretical foundation we have used Dorte Skot-Hansensmodel of the public library as a third place and Mikael Stigendalstheory on social inclusion. Furthermore have we used research onthe public library as a meeting place and social integration as acomplement to the model and the theory.Conclusions from the material gathered is that public librarianssee the public library as a meeting place with potential tocontribute to integrating individuals and groups with one another.The librarians? foremost method was to attract visitors withactivities aimed at certain target groups.

Introduktion: Personer med funktionsnedsättning har nedsatt förmåga att fungera fysiskt, psykiskt eller intellektuellt, vilket kan medföra hinder med att sköta den dagliga munhygienen. I omvårdnaden i bostad med särskild service för vuxna ingår skyldighet att stödja funktionsnedsatta med deras personliga behov.Syfte: Syftet med studien var att undersöka boendeassistenters kunskap om munhälsa. Ytterligare ett syfte var att undersöka boendeassistenters inställning till munvård samt faktorer som påverkar deras inställning till munvård.Material och metod: Studien är en kvantitativ tvärsnittstudie baserad på en enkät med 31 strukturerade frågor samt en öppen fråga.  Enkäten besvarades av 43 boendeassistenter i en kommun i södra Sverige.Resultat: Resultatet visar att majoriteten (n=34) av boendeassistenterna anser att de boende behöver dagligt stöd med munhygienen. Det största hindret är att de boende inte vill ha hjälp med munhygienen. En stor del (n=31) av boendeassistenterna anser att de har tillräcklig kunskap om munvård för att stödja de boende med den dagliga munhygienen.

Studien avser att studera effekterna av arbetsplatsförlagd fysisk träning 2 x 60 minuter/vecka i 7 veckor hos personer med stillasittande arbete påVO2max, rörlighet, uthållighetsstyrka och kroppssammansättning. Vi använder oss av en kvantitativ metod som består av datainsamling genom tester före och efter träningsperioden för både interventionsgruppen (n=25) och kontrollgruppen (n=11). Resultaten visar på signifikanta skillnader hos interventionsgruppen på variablerna VO2max (p=0), visceralt fett (p=0,001), fettmassa (p=0,001), vikt (p=0.006), Body Mass Index, BMI (p=0,005), uthållighetsstyrka enligt Sörensens isometriska uthållighetstest (SIU) (p=0) och Trunk Curl Static Endurance test (TCST) (p=0,045), rörlighet i halsrygg (p=0,010) och rörlighet i hamstringsmuskulatur via Sit and reach test (p=0).  Inga skillnader ses i blodtryck och, skelettmuskelmassa i armar, bål och ben. Inga signifikanta skillnader ses hos kontrollgruppen oavsett variabel. Slutsatser av studien är att man kan se effekter genom denna typ av intervention på flera olika variabler och förslag till framtida forskning är att försöka utesluta samverkan av andra faktorer för att ge en mer exakt bild av den fysiska träningens effekter på arbetsplatsförlagd träning..

This report deals with hard surfaces and the factors which are behind the criteria for dimensioning, also dependent on the level, or volume, of traffic. A test was made on slabs of two kinds of natural stone. This was made to see if the values that were reached for breakload was transferable to the same tables that the concrete industry is using for surface dimensions of slabs and paving stones. The test showed very high values and the result, together with the written study, led to the author?s suggestion for a classification table where slabs of natural stone were divided in to different classes depending on traffic, thickness and durability..
