Självskattad hälsorelaterad livskvalitet hos kvinnor och män med fetma
Fetma utgör ett folkhälsoproblem. Fokusering på vikt och olika risker med fetma är otillräckligt för att förstå hur personers hälsorelaterade livskvalitet påverkas. Studiens syfte var att beskriva självskattad hälsorelaterad livskvalitet hos personer med fetma. Kvantitativ ansats valdes och 100 personer med ett BMI mer än 30 besvarade ett självskattande instrument, SF-36. Dataanalys genomfördes med korrelations test för att få styrkan i samband mellan variabler.
Utvärdering av en beslutsåterkopplad kanalestimator för tredje generationens mobiltelefonisystem
This Masters thesis work describes a comparison between two different methods
for estimation of the down channel (base station to mobile subscriber) in
Wide-band Code Division Multiple Access (WCDMA).
The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is
a conventional method that bases the estimates on data that is known to both
sender and receiver, so called pilots. The second method, Decision Directed
Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data
for estimation.
Simulations show that DDCE, in comparison to OFCE, does not attain an
improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER). An
improvement is only seen when the BER becomes much lower than what is common in
real situations.
In conclusion DDCE is complicated, involves many mathematical operations and
gives insignificant improvement of SNR when BER takes common values. It is
legitimate to question if it is possible to use the method in a real mobile
phone system..
En studie av metodbyte vid sintring av hårdmetaller till mikrovågsintring samt dess ekonomiska fördelar : Självständigt arbete i teknisk fysik med materialvetenskap & Självständigt arbete i kemiteknik
The aim with this study was to investigate the effects a change of manufacturing process would have on the mechanical properties of drill bits made of a WC/Co composite used for stone cutting. The method used today is sintering, where the material is heated in a conventional sintering oven. The other method was microwave sintering, where the material is heated by radiation in the microwave region. Also an investigation of the manufacturing cost were made.The main difference between the two heating methods is that the conventional way is a rather slow process and the microwave method is very fast. The material is also heated homogeniously in the method with mirowaves, aposed to the case with the conventional sintering where the material is heated from the outside in.This makes the material harder and more wear resistent.
Simulatorträning som ett redskap för att förbättra procedurell kunskap
Anestesören arbetar i en miljö som är dynamisk och komplex vilket gör att det krävs att de kan utföra sekvenser av moment på automatik eftersom det oftast inte finns tid till djupare beslutsöverläggningar. Vid Huddinge Unviersitetssjukhus finns METI som är en patientsimulator. Denna simulator används idag för att öva medicine kandidater i att ge anestesi. Detta arbete undersöker om simulatorträning kan förbättra medicine kandidaters procedurella färdigheter. Undersökningen är en enkätundersökning där frågor som sökte ta reda på deltagarnas procedurella ställdes.
Äldre dövas arbetsminne
Denna studies syfte var att undersöka om dövas åldersförändringar i arbetsminnesbearbetning skiljer sig från hörandes. Fyra grupper deltog, döva (teckenspråkiga) och hörande (icke teckenspråkiga), indelade i grupper om yngre och äldre (> 65 år). Femtiosex personer deltog, jämnt fördelade över de fyra grupperna. Samtliga fick genomgå ett arbetsminnestest indelat i tre delar, ett spatialt, ett temporalt och ett spatialt - temporalt test. Den spatiala naturen hos teckenspråket förväntades leda till en relativt sett förstärkt funktion i detta test hos de teckenspråkiga.
Med siktet inställt på bragd, hinder och hopp : En granskning av handikappidrottens plats i det mediala rummet
Purpose/Aim: The aim of this study is to (1) analyze the amount of exposure disability sports get in Swedens biggest newspaper (Aftonbladet), (2) look at how Aftonbladet portraits disability sports and it?s athletes, and finally (3) to see if there has occurred any change over time (during the last eight years). Material/Method: The first method used is a quantitative analysis to measure exposure.The second method is a quantitative content analysis which is used to analyze how disability sports are portrait.The third method is rhetorical and is also used to analyze how disability sports are portrayed. Main results: The study has shown that disability sports get very little exposure in Aftonbladet. The articles in the newspaper that cover disability sports are portrayed from a personal point of view without much focus on the athletes achievements regarding his or her sport.

IT-kompetens : utveckling av ett mätinstrument
Problem: In society of today corporate competence is an important factor for survivor and development. IT is developing rapidly and can not be ignored by companies. Then need for people with IT-competence is conquent increasing. A survey of corporate IT-competence is therefore of interest for companies as well as for local authorities. To determine the IT competence within an organisation, this competence has to be measurable.
Närsaltsdosering till luftad damm : en åtgärd för ökad TOC-reduktion hos Skoghalls Bruk luftade damm
In the process of making carton boards into Skoghall Mill, are great quantities of water being contaminated. This water has to be treated before it is possible to release into the recipient, Kattfjorden. One of the contaminations that is important to extract from the wastewater, is organic carbon (measured as TOC-total organic carbon) because microbiological breakdown can lead to the bottom becomig free of oxygen.The wastewater treatment at Skoghall Mill is done through an external wastewater treatment that is located at the factory. The biological treatment (aerated lagoon) is a 140 000 m3 water pool with surface aerator, which is give oxygen to the water. In the lagoon live microorganisms who performs the biggest part of the TOC-reduction.One problem with the lagoon is that the treatment of TOC is considerably worse during wintertime than during summertime.
Mäns och kvinnors possible selves om framtida arbetsliv
Människors yrkesval och syn på framtida arbetsliv influeras av olika faktorer som i sin tur har formats av evolutionen eller den sociala omgivningen. Människans kognitiva förmågor är ett av elementen som påverkar yrkesvalsprocessen, men är också kanske en bidragande orsak till könssegregeringen på arbetsmarknaden. Hur människor ser sig själva i den framtida yrkesrollen kan också vara en anledning till varför det finns en könsskillnad på arbetsmarknaden. Markus and Nurius (1987) har myntat begreppet ?Possible self?, vilket de definierade som självbilden i framtida situationer.
Korta musikresor (KMR) : Mot en teori om KMR som en musikterapeutisk metod
This study was conducted in the Master program at The Music Pedagogical Center (MPC) at The Royal College of Music in Stockholm. Korta musikresor (Short Music Journeys) is the Swedish term used for a receptive method of music therapy adapted from the tradition of The Bonny Method of Guided Imagery and Music (BMGIM) and the theory and practice of Expressive Arts Therapy. The KMR method uses carefully selected short pieces of music, lasting between 2 and 5 minutes, to work on various psychological problems and life- crises. The music session is conducted in a slightly altered state of consciousness with a clear focus being established beforehand in a verbal dialogue with the psychotherapist. There is also the possibility of using artwork to process and explore the imagery after the music listening.
En jämförelse avseende beståndsgående-och stickvägsgående gallringsmaskiner
The purpose of this report is to investigate and compare the difference between stand-thinning machines and strip-road thinning machines, and how they affect the stand on behalf of future growth, theoretical economic result, wind impact, snow pressure and density of stand.
The investigation is regarding the first commercial thinning of pine stands, after pre-commercial thinning that was well conducted.
The investigation area was located near Katrineholm, Sweden. The measurements that were measured were strength of thinning and amounts of wind throws, snow-breaks and hauling damages.
The results that emerged, was that thinning with strip-road machines had a significantly higher strength of thinning over all, as compared with the stand- thinning machines (45 percent versus 30 percent).
Comparisons between wind-throws, snow-breaks and hauling damages of the stand could not establish any significant differences between the two methods that were investigated.
Conclusions, over all, were that if forest owners want to have more timber volume left for second thinning and final cut of the stand, the forest owners should choose the method with stand-thinning machines. From the point of view of gentle treatment of the stand and ground damages the choice should be the same.
However, the method with strip-road thinning machines is the most common and accessible method in Sweden. Most likely it is the most economical way to manage the stand for forest owners in present time.
If the method with stand-thinning machines is becoming more common in Sweden, it is suggested for forest owners to consider the stand-thinning method as a candidate for treatment due to economic aspects..
MATERMINO : utformning och prövning av ett begreppsförklaringsspel i geometri för grundskolans senare år
Syftet med denna studie var att undersöka hur ett pedagogiskt spel för grundskolans senare år som övar geometriska begrepp kan utformas samt huruvida det kan fungera som ett givande komplement till befintliga material för geometrisk begreppsinlärning. Spelet, som kom att kallas MATERMINO, testades av 33 elever (15 flickor och 18 pojkar) i skolår 6. Dessa elever samt tre lärare för grundskolans senare år bedömde sedan spelet; de förstnämnda i enkäter och de senare i intervjuer. MATERMINO bedömdes främst passa elever i skolår 6-8. Vidare visade studien att MATERMINO var omtyckt och roligt och att spelet tycktes leda till inlärning gällande geometriska begrepp.
Diversifieringsmöjligheter och deras effekt på avkastning : en jämförande studie av etiska och traditionella fonder
Aim: Based on portfolio theory, which highlights diversification, and CSR, which describes the value of social and ethical responsibility of corporations, this study examines whether there is a difference in risk-adjusted performance between ethical and traditional mutual funds. Ethical funds are limited in their opportunities of diversification and should therefore be limited in their potential perfomance. On the other hand, a focus on social and ethical responsibility can be profitable.Method: The study uses a quantitative approach where we used 25 mutual fund in each category, ethical and conventional mutual funds. The mutual funds and their data has been obtained from www.morningstar.se and www.pensionmyndigheten.se. Historical performance between 2009-2013 were processed to obtain the Sharpe ratio and M2.
?Developing a crucial business plan template targeted to Swedish Venture Capitalists?
Objective To study if the Swedish venture capitalists consider business plans in their screening process, and in such case, what aspects they evaluate in order to develop a targeted template for Swedish entrepreneurs. A secondary objective is to describe what other factors Swedish venture capitalists evaluate as a part of their assessment. Methodology The method, which has been used in order to test the objective, has been carried out through extensive literature and article studies, interviews, and distribution of a short and comprehensive questionnaire to a multiplicity of venture capitalists throughout Sweden. Conclusion Generally, the findings of this thesis suggest that a business plan should include elements such as a summary of important elements, a thorough market analysis, financial information, exit strategy, and the risks associated with the project. The empirical material also reveals that venture capitalists also evaluate factors such as ownership influence, the entrepreneur?s industry knowledge, product knowledge and the personal chemistry in their evaluation process.
