This thesis describes a method of measuring axial magnetic leakage flux in an operational hydropower generator. Axial magnetic leakage flux is the magnetic flux at the ends of a rotating generator, which goes through the stator parallel to the rotor axis. This flux can cause circulating currents in the stator iron, giving rise to losses, and can in the worst case overheat a generator, causing it to melt down. To measure the axial flux, and how it affects the generator temperature, a measurement system was constructed on behalf of Vattenfall. The system consists of search coil sensors and a signal-processing unit with amplifiers and active filtering.  To confirm the behaviour of the axial leakage flux and the functionality of the measurement system, a test installation was made.

Syftet med det här arbetet är att återskapa en förutbestämd intensitetskurva inom ett tvådimensionellt plattformsspel. Arbetet bygger främst på teorier av Mike Lopez som han publicerat i ett antal artiklar på Gamasutra. Lopez artiklar handlar om spelprogression, dvs. hur man ska gå tillväga för att behålla spelarens intresse genom hela spelomgången, och att ha en bra intensitetskurva är en del av progressionen.Under arbetets gång skapas ett spel som sedan en testgrupp får spela igenom. Under testningen mäts deras puls, och den data som utvinns används för att skapa en graf och jämförs sedan med den intensitetskurva som skulle efterliknas.

ABSTRACT Introduction: This study is based on Aantonovskys SOC-theory; Sense of Coherence. SOC can be described as a theory which describes how a person experience her existence and the theory is based on three key expressions; comprehensibility, manageability and meaningfulness. Aim: The aim of the study is to examine a group of elderly (>80 years) men and women who live alone to investigate how many percent of the group that estimate a high value of SOC. The study aims to investigate which factors contribute to the fact that a person achieve a high value of SOC and increase the understanding about how these factors concretely can appear in a persons life. Methods: Questionnaire (SOC scale) and Interviews.

AimThe purpose of this study was to investigate the relationship between self-perceived health and level of physical activity among the staff at The Swedish School of Sport and Health Sciences (GIH). We focused on the following questions:How does the amount of physical activity affect the self-perceived health among the staff at GIH?  Are there any gender differences in self-perceived health following the amount of physical activity? Do the self-perceived health and the amount of physical activity differ between the various age groups? Are there any differences between the staff responsible for health education compared with the other staff?MethodWe chose a validated questionnaire for our study. It was a combination of two already previously validated questionnaires together with our own supplementary background questions. The questionnaire was presented to 96 respondents and we received 76 answers.

The ability to detect protein-based biomarkers, which are linked to different diseases like colorectal cancer, is very important as a diagnostic tool. Usually complex biological samples like blood are studied which will contribute to different technical issues when performing an assay. The aim with the project is to optimize and develop the high throughput protein detection technique Proximity Extension Assay, PEA, into a 96-plex panel, in hopes of discovering an expression profile for colorectal cancer. PEA was developed by Olink Bioscience and allows specific proteins in a sample to be quantitatively transformed into nucleic acid sequences that are subsequently detected and quantified with real-time PCR. Two proximity probes containing oligonucleotide sequences bind pairwise to target protein and when brought in proximity, a DNA polymerase will extend a hybridization arm from one probe over to the second forming a double-stranded DNA sequence that can serve as a template in real-time PCR.

Syfte: Syftet med undersökningen är att se om, och i så fall hur, elevernas antal steg samt upplevda ansträngningsnivå under lektioner i idrott och hälsa påverkas av vilket tempo bakgrundsmusiken har. Metod: Studien utfördes på 83 gymnasieelever från två olika skolor (varav 35 elevers resultat slutligen kunnat användas). Eleverna genomförde två till synes identiska lektioner vardera, där huvudmomentet bestod av en stationsbana. Den ena lektionen genomfördes till musik med ett BPM[1] högre än 140, medan den andra hade under 120 BPM. Två av klasserna började med musik i det lägre tempot och två med musik i det högre tempot.

The purpose of this study is to map out and to analyze the spatial variation of female representation at the national level in established democracies. The aim is also to explain the variation in the female representation. The main questions that the paper tries to answer are:1.How does women representation in established democratic parliaments vary?2.Why does women representation in established democratic parliaments vary?This study is a comparative and statistic study, i.e. a study that includes a bigger number of countries and where quantitative analysis methods are used in order to achieve comparative analyses.

In Sweden plans to build high speed railways have been around since the early 1990s and the planshave developed to be more precised since. The future Swedish high-speed rail network is supposedto consist of two lines. Götalandsbanan; from Stockholm to Gothenburg, and Europabanan fromJönköping through the Öresund Region to Hamburg.The description of the aim to build high-speed railways in Sweden has in former reports always beento achieve rapid passenger traffic between big Scandinavian cities and Europe. There are almostnothing mentioned about the possibilities of high-speed transports of cargo on these railways. Thisstudy aims to clarify the freight transport market for Götalandsbanan and Europabanan.Today there is only one transport system with high-speed freight trains.

Bakgrund: Sverige står inför stora förändringar i arbetslivet i allmänhet och i sjukvården i synnerhet. Detta med hänsyn till stora pensionsavgångar de närmaste åren som innebär att allt färre skall försörja allt fler och en åldersstruktur som i ökad utsträckning kommer att efterfråga sjukvård i större omfattning. Med detta för ögonen står vi inför utmaningar inom arbetslivsforskningen för att hitta faktorer till hållbar arbetsförmåga högt upp i åren.Syfte: Denna pilotstudie har haft som syfte att inventera attityder och upplevda förutsättningar hos sjukhusanställda läkare och undersköterskor och deras arbetsgivare, som skulle kunna möjliggöra en hållbar arbetsförmåga hos äldre arbetstagare. Undersökt grupp och metod: Strategiskt valdes 14 representanter äldre än 50 år från arbetsgivarsidan (n=6) och arbetstagarsidan (n=8), män (n=6) och kvinnor (n=8) samt från grupperna undersköterskor (n=4) och läkare (n=4). Från arbetsgivarsidan ingick både verksamhetschef (n=2), avdelningschef (n=2) och sjukhusledningen (n=2).

This thesis suggests an explanation for how it is possible for individuals living in an unsafe neighborhood to expressa highlevel of security. Araby is the district in Växjö municipality withthe highest level of insecurity. Within the district, there is acategory of individuals in security-measurements showing a high degree of security. Inhabitants living in house in Araby also seem to show a higher level of security than inhabitants in the same accommodation in other neighborhoods in the municipality.The study's purpose is to understand how individuals belonging to an unsafe neighborhood can experience a high degree of security.Qualitative data were collected from an observation in Araby and from interviews with individuals living in house in the district.Previous research has shown that security in the surrounding area depends on several factors, such as disorders, the degree of social control and personal opinions. Thestudy shows how a distinction to places and people in the district can explain the degree of security.

This document presents calculations of adjusted GDP based on satellite household accounts for the year 2001 with the purpose to compare adjusted and official GDP for Sweden, Germany, Estonia and Finland. Household production in each country is estimated using time use survey data from Eurostat and a monetary value is estimated using average wage (after taxes) for each country. The results indicate that the value of household production using this methodology increases GDP with between 42% (Finland) and 55% (Germany) compared to official GDP statistics. A comparison of GDP/capita between the countries included in the study shows that the GDP/capita in Germany increases more that the other countries due to the relatively high proportion of time used for household production (mainly German women) combined with a high average wage. In fact, the results show that Germany has higher adjusted GDP/capita than both Finland and Sweden (but Germany has lower GDP per capita when official statistics is used for the comparison).

The purpose of this paper is to try to get an understanding of the underlying causes and reasons that students starting in seventh grade junior high school seek out a particular group, and the extent to which they do so.The work is based on the questions: How do students perceive the meeting with their prospective bench-companion in a new composite class? What should a teacher consider when it comes to bench placement in a new composite class? Do the students change, and if so to what extent, friends when they start high school? What are the factors that affect/have affected the students' choice of friends? How large a role does the school play for pupils relationships? What thoughts and feelings do the students have regarding new encounters?I have conducted in-depth interviews with six adolescents in grade seven as the basis for the understanding of how students relate to group selection and group affiliation, and I have then compared this material with previous research on the subject. Furthermore I have availed myself of literature in social- and group psychology.The conclusion which has emerged is that the most important component of a group-process is the sense of solidarity and security, and the results show that students largely retain their old relationships rather than adding new, when they start high school. Hence the teacher plays an important role in ensuring that any imbalance in the group is offset and make sure that nobody is excluded, but also to help make room for new groups and be aware of the sensitive and responsive phase of life that the young people are in..

Syftet med studien var att beskriva långtidssjukskrivna kvinnors upplevelser av delaktighet i aktivitet. Åtta långtidssjukskrivna kvinnor mellan 44-58 år ingick i studien. Datainsamlingen skedde i form av ostrukturerade intervjuer och analyserades utifrån en komparativ analysprocess. Detta resulterade i en kärnkategori: ? Upplevelsen av delaktighet i aktivitet vid långtidssjukskrivning? och fyra underkategorier: ?Anpassning av självbild och värderingar?, ?Anpassning av tid och tempo?, ?Anpassning av aktivitetsutförande? och ?Anpassning av social miljö?.

High technology companies in Sweden spend a huge amount of money on research and product development in proportion to what they get back in earnings from their inventions. Product development has traditionally been regarded as much more important than business development. This thesis aims to point out the critical factors behind successful business development processes for high technology companies. We have chosen to make a case study of Hexagon, a highly successful and innovative company within the measurement technology business. Internal and external actors that are important for business development have been identified and interviewed in order to understand how ideas are developed and executed.
