Is less more?
Back in the 1950s Marilyn Monroe and her hourglass shaped body was the aesthetic ideal for how models were to look like. Nowadays, the tide has turned. Research has shown that female models are becoming increasingly taller, narrower and straighter. This trend has occurred despite the fact that both men and women (still) prefer medium sized women with curvy bodies. This essay examines if this trend can be justified from a marketer's perspective.
AP-fondernas fastighetsinvesteringar - en framgångsrik diversifieringsstrategi?
Sverige har ett för världen unikt pensionssystem i det att systemet tar hänsyn till den ekonomiska och demografiska utvecklingen samt att det i systemets konstruktion finns ett pensionsreservsystem med fyra separata fonder, AP-fonder. Dessa fyra fonder som även går under benämningen buffertfonder har en viktig funktion att fylla när det gäller den långsiktiga finansieringen och i sin roll att fungera som buffert i tider av stora påfrestningar för pensionssystemet. Denna studie undersöker och analyserar 1-4 AP-fondernas uttalade strategi om att diversifiera sina totalportföljer i syfte att få en mer robust portfölj som bättre kan tåla finansiella påfrestningar. En del i AP-fondernas strategi för att uppnå diversifieringsfördelar är att låta sina fastighetsportföljer växa och ta en större andel av totalportföljen. Studien undersöker vilka konsekvenserna har blivit för fastighetsportföljernas andel av totalportföljen till följd av den uttalade diversifieringsstrategin samt hur utfallet har varit för dessa fastighetsportföljer under 2003-2012.
Konvertering från UDK till SAB
The main purpose of this thesis is to examine what problems may arise when converting class symbols from one classification scheme to another. In order to fulfill this purpose, a conversion table between parts of the Swedish online-version of the UDC and the Swedish classification system SAB was constructed. For main classes 0 and 3 every class number from this abridged version of the UDC was converted, whereas for the rest of the main classes only class numbers with fewer than four figures were converted. The conversion table was constructed using the alphabetical index of SAB and different UDC-indexed library catalogues. Various aspects of the conversion table were then analysed using methods mainly devised by the authors themselves, but inspired by lexicography and multilingual thesaurus construction.
Verktyg för lönsamhetsberäkningar vid bränslekonvertering av spetslastpannor från olja till pellets
This report summarizes the development of a calculation program estimating the profitability of converting a peak-load oil-fired boiler to pellets. To convert an oil-fired boiler to pellets a new fuel handling system must be designed. Changes also have to be made to some other components. Since there are many different techniques for transportation, storage and treatment of the fuel only the most interesting techniques from Swecos experience and interest were included in the study.The capacity of the different parts in the system was dimensioned based on the power of the boiler after conversion. To estimate prices, installed power and dimensions manufacturers and distributers were contacted.
Motiverad för riskmedvetenhet? En studie om stadsarkitekterna i Dalarnas läns medvetenhet om, motivation för och arbete med risker vid fysisk planering.
The purpose of this study is to examine how risk is perceived by the urban architect's in the region Dalarna, as well as how this is reflected in their everyday work with risk and decision- making according to urban planning. The ambition is also to show how their risk awareness could be improved. The study is written in cooperation with Länsstyrelsen Dalarna as a part of their regional long-term goal to improve the region's proactive risk' and crisis management. The study is based upon 12 semi-structured interviews with local urban architects conducted during the summer and autumn 2007. The result shows that some architects are motivated for working with risk and think that risk awareness should be integrated in their everyday work, while others are not motivated and think that risk is more of a passing trend.
Diagnostiksystem i gaffeltruckar
This is a final thesis done at BT, considering one of their forklift truck models called Reflex. The first part of this report is about a preliminary investigation investigating what kind of diagnostic systems BTwants to use, and also which demands there are to meet all expectations on such system. Secondly a diagnostic system, which will show if the drive wheel is worn out, will be presented. In the preliminary investigation, two kinds of diagnostic systems were mentioned. These were Model based diagnosis and Predictive analysis.
Upplevelser av skam och avvisande hos deprimerade unga vuxna
Depression in young adults is a serious condition causing serious suffering for the victim. By finding risk factors for depression the opportunity for early preventive action is increased, which, in turn, may prevent a negative course. Two risk factors which have been shown to be related to depression are shame and rejection. Therefore this study examined the relationship between shameproneness, rejection sensitivity, shame-related events and depressive symptoms. The self-report questionnaires used were TOSCA, RSQ, Shaming index and BDI-II.
Acceptansgränsen för solceller i lågspänningsnät : Kan den ökas?
Microproduction, also called distributed generation, is something that has become more and more popular in the electric grid. Microproduction can however lead to unacceptable performance if several units are installed in the same low voltage network. It is therefore good to know a limit where the performance of the low voltage network becomes unacceptable based on given parameters. This limit is usually called hosting capacity.In this report the hosting capacity with respect to voltage and current have been studied in three low voltage networks which are located in Falu Elnäts concession area. This has been done by simulations in a GIS-program where critical times of the grid have been simulated.
Postaktiveringspotentiering i knäböj med hjälp av countermovement jumps
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..
Investigation of yeast Grown in SSF Dring Biothanol Production from Lignocellusosic Material
Ethanol produced from lignocellulosic biomass has the potential to become a promisingalternative to gasoline. In this work the simultaneous saccharification and fermentation (SSF)technology was applied for ethanol production from hardwood with focus on cell growth,ethanol production and contamination.The SSF was performed at PH 5.5 and 35°C for different suspended solid concentrations(8%, 10% and 12%) of pretreated birch slurry which contained 16 % total suspended solids.Two different hexose fermenting yeast strain (Ethanol Red) and pentose fermenting yeaststrain were used.Quantifying the concentration of chemical components and metabolites in the fermentationmedium demonstrated that glucose and xylose are the major fermentable sugars in the slurry.The higher load of slurry (12%) represents a higher content of carbohydrates and potentiallyhigher end concentration of ethanol. Moreover, more lactic acid is produced with the lowerload of slurry (8 % or 10 %), presumably due to a result of a less inhibitory environment forbacterial growth. In this context, acetic acid sticks out as the most important inhibitor withconcentrations of 15.2 and 12.5 and 9.7 g/l respectively in the 12 %, 10 % and 8 % (ofsuspended solids) trials. Using pentose fermenting yeast may lead to higher ethanolproduction, lower xylose uptake and lower lactic acid formation.
Mjölkureahalten som mått på vommikrobernas kväveförsörjning och kons miljöbelastning
The aim of this literature study was to analyze how milk urea concentration is working as a measure of the nitrogen supply to rumen microbes and indicator of the environmental load. Questions included in this literature study were how to improve the dairy cattle nitrogen efficiency and what correlations there are between milk urea, nitrogen efficiency and crude protein content in the feed. Effects on the reproduction from high ration protein content are also addressed. Dairy cattle are today fed with large proportions of protein which could lead to high expenditure of feed and environmental pollutions. The nitrogen can be lost to the environment by different pathways; leaching, denitrification or by emission to the air.

Att skriva om händelse, tanke och känsla: en explorativ studie kring effekter av expressivt skrivande i skolmiljö på ungdomars emotionsreglering
As part of the project Self esteem and Life circumstances among teenagers (started by Johnsson, Lundh & Wångby at Lund University in 2006) results from pilot studies of expressive writing (intervention initially created by Pennebaker and Beall, 1986) among adolescents in six secondary school classes in Sweden were investigated. The study describes changes from pre-test to follow-up on adapted versions of Emotion Regulation Questionnaire and Emotional Tone Index. Different strategies for emotion regulation are focused: voluntary and involuntary engagement and voluntary disengagement (Connor-Smith, Compas, Wadsworth, Harding Thomsen & Saltzman, 2000). The study is explorative. Results show a tendency towards more frequent diary use at follow-up for participants in expressive writing.
Är medberoende i högre grad utbrända/utmattade än en kontrollgrupp med ej medberoende studenter?
Stress i arbetslivet anses vara den främsta orsaken till utbrändhet/utmattningssyndrom, men det finns forskare som menar att det är värt att även studera individfaktorer i detta sammanhang. Syftet med denna studie var att fokusera på ohälsa bland medberoende individer genom att undersöka om dessa var mer utbrända/utmattade än icke medberoende. I undersökningen deltog 92 personer. 45 studenter ingick i en kontrollgrupp och 47 medlemmar i självhjälpsrörelsen Alanon ingick i experimentgruppen.Deltagarna besvarade en enkät, bestående av två självskattningsformulär; Karolinskas utbrändhetsformulär samt ?the Holyoake Co-Dependency Index?.
Muskelstyrka i lårmuskulatur efter operation av främre korsbandet ? finns skillnader avseende ålder och kön?
Det finns idag ingen konsensus om den optimala rehabiliteringen efter en främrekorsbandsrekonstruktion, vi vet heller inte idag huruvida rehabiliteringen skaspecificeras efter parametrar som kön och ålder. Studien var en korrelerandetvärsnittsstudie med syfte att ta reda på om det förelåg någon skillnad i postoperativlårmuskelstyrka 4-7 månader efter en korsbandsrekonstruktion med avseende på kön,ålder, skada och typ av operativt ingrepp. Av de 330 aktuella försökspersonerna var detendast 74 personer som godkänt deltagande och uppfyllde kraven förinklusionskriterierna. Försökspersonerna testades i en isokinetisk dynamometer(Biodex)för maximal styrka(60gr/s) och uthållig styrka(180gr/s). Resultaten presenteradesgenom ett Limb Symmetry Index.
