Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Vitamin D supplementation and its effect on body composition in the overweightand obese ? a systematic reviewAuthor: Johanna Blum and Emma Sellin FrimodigSupervisor: Sofia KlingbergExaminer: Ingrid LarssonProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: April 10, 2013Background: There is an increasing burden of overweight and obesity worldwide. Theconditions lead to morbidity and lowered quality of life. Since there is research showing aconnection between obesity and low levels of serum 25(OH)D, this raises the question ifsupplementation of vitamin D may have positive effects on body weight, waist circumference andbody composition in the overweight and obese.Objective: To investigate if there is enough scientific evidence to recommend vitamin Dsupplementation combined with nutrition therapy to overweight and obese patients.Search strategy: The systematic collection of data was performed in the databases PubMed andScopus. Search terms included were ?vitamin D supplementation?, ?obesity? ?cohort?, ?vitamin D?,?vitamin D3 supplementation? and ?overweight?.Selection criteria: Human studies with RCT, CCT or cohort design written in English orSwedish were included.
TOMO Hugglink
Tomo Hugglink (TOMO Skog) is an innovation for harvest and transport of biofuels. The system consists of a truck, a chipping unit and crane mounted on a link and a wood chip trailer. The system works in such a way that the chipping unit is disconnected and placed on the site and wood chips are loaded directly into the wood chip trailer.The aim of this study was:- To examine the performance of the TOMO Hugglink system under different conditions such as the size, placement and quality of the pile.- To calculate the cost per raw ton for two vehicle combinations at different transport distances and to examine the effect of a reduction in set-up time and an increase in load weight.- To identify possible improvements with the TOMO Hugglink system.A time study was conducted within the thesis work to make it possible to determine production and time consumption. In the subsequent economic analysis the cost per tone at different transport distances was calculated for two different lorry concepts. Furthermore the effect of a reduction in set-up time and an increase in load weight was calculated.Under current conditions the utilization of the chipper is low and only 29 % of the total system time is occupied by chipping.
Psykologiska mekanismer och miljöperspektivet - sambandet mellan attityder och beteendeintentioner inför samhällets miljöpåverkan
Syftet med studien var att pröva vilka psykologiska mekanismer som påverkar
sambandet mellan attityder och beteendeintentioner inför miljöpåverkan hos
individer i konsumtionssamhället. Hypotesen var att det finns ett
miljömedvetande hos människan, men att det är en skillnad mellan attityd och
beteendeintention.
Även emotioner inför miljöpåverkan hos deltagarna undersöktes, för att fördjupa
studien. Undersökningen har gjorts kvantitativt via en webbaserad enkät, genom
utskick via Facebook till vuxna individer i Sverige mellan 18-65 år (N=49).
Svarsprocenten var 46 procent. Huvudresultatet visar att det finns en oro hos
individer inför miljön och framtiden och 94 procent av deltagarna anser att
miljöfrågor är viktiga.
Industriklassificeringens roll som urvalskriterium vid multipelvärdering
This thesis aims to investigate if peer-groups based on industry classification perform as well as, or better than, peer-groups based on other measures that represent factors affecting the price-to-earnings multiple. In contrast with previous empirical studies, a solid theoretical approach is used in defining which factors, according to valuation theory, affect the P/E-ratio. The factors identified as explanatory are accounting measures, risk and growth. Furthermore, we have recognized several measures that represent these factors. These measures are tested for accuracy of prediction in terms of the P/E-ratio for peer-groups based on these measures relative to an industry classified peer-group.
IP-telefoni - En explorativ studie om vad som påverkar konsumenters användande av IP-telefoni:
Despite the fast growing development of IP-telephony services, only a small number of people in Sweden use them. Of the total amount of fixed telephony subscriptions, maximally five percent are based on IP-technology. Through an exploratory study, the main purpose with this thesis is to identify factors that influence the use of IP-telephony on the consumer market, and the factors? internal relationships. The thesis also has two sub-purposes: firstly, chart the supply of IP-telephony services and secondly, discuss what IP-telephony services that are requested by today?s customers in the future.

Hellre överkvalificerad än undersysselsatt - om övergångsfrekvensen till högre utbildning i Sverige under 80 år
This essay aims to explain the fluctuations in the Swedish transition rate to higher education between 1923 and 2002. With theories of human capital, and screening, as points of departure, seven variables are selected and their correlation with the transition rate investigated by use of graphs and tables. The variables are unemployment, youth unemployment, the supply of academics, cohort size, number of high school graduates from programs preparing for ensuing studies, relative wage trends for worker categories with differing levels of education, and structural phase. Results show that no single variable nor the theories of human capital or screening can explain the fluctuations in transition rate in full. Instead I propose a theoretic model which amalgamates the above and places risk aversion as the driving force behind the individual?s educational decision.

Processbeskrivning av Rundvirkestransport : En Fallstudie hos Tra?frakt Go?taland AB
Title: Process description of round timber transports ? a case study at Tra?frakt Go?taland ABAuthors: Karl ? Johan Tern, Christian Johansson and Andreas IvarssonTutor: Anders JerrelingExaminer: Fredrik KarlssonBackground: Today the profitability of forest haulers is unsatisfactory. Negotiations on prices are more about the relative strength of the negotiation parties rather than a discussion about actual costs. Adding extensive changes in the forest haulers cost structure has led to insufficient knowledge of whether the negotiated prices really correspond to their costs.Methodology: We decided to carry out a case study at Tra?frakt Go?taland AB, a special interest organisation whose members represent the majority of forest haulers in Go?taland.Purpose: To describe the processes and underlying activities of round timber transports.
Självskadebeteende och riskbeteende för ätstörningar hos tonåringar: förekomst, samband och intervention med expressivt skrivande
The purpose of the present essay, as part of the project Self esteem and Life circumstances among teenagers, was to investigate the rate of both deliberate self-harm (DSH) and risk behaviour related to eating disorders in 14-year-old swedish adolescents, gender differences in DSH, and possible correlations between DSH and risk behaviours related to eating disorder. In addition, the effects of expressive writing (Pennebaker & Beall, 1986) on DSH and risk behaviours related to eating disorders were investigated. Data from two pilot studies are included. In total, 198 14-year-olds from four different schools in southern Sweden participated. For the purpose of measuring the rate of DSH, a simplified version of Gratz's (2001) Deliberate Self-Harm Inventory (DSHI) was used.
De anhörigas sjukdom : Anhörigas upplevelser av att vårda personer med Alzheimers sjukdom
Bakgrund: I Sverige finns det cirka 160 000 personer som är drabbade av någon form av demenssjukdom och av dessa lider ca 60 % av Alzheimers sjukdom. Cirka en halv miljon svenskar beräknas vara anhöriga till någon som drabbats av Alzheimers sjukdom. Alzheimers kallas ibland för de anhörigas sjukdom, eftersom livssituationen förändras både för den drabbade och för de anhöriga. Syfte: Att beskriva anhörigas upplevelser av att vårda personer med Alzheimers sjukdom. Metod: Studien utfördes som en allmän litteraturstudie.
Det svenska kapitalkravet underminerat och förlegat? : En jämförande studie av den svenska och engelska bolagsrätten i ljuset av etableringsfriheten
The harmonization within EC Company Law has been relativley successful. Despite its relative success; important differences still remains in European company law.The freedom of establishment itself, and the ECJ?s interpretation of the freedom provides European companies with a substantial cross-border mobility. As a consequence of this mobility, together with the differences in national legislation; mandatory rules in company law can be easily evaded. A typical example of this is that a Swedish enterprise, by running their business through a British private limited company, can escape the Swedish legislation on capital contributions when forming a company with limited liability for its members.
Upprepade ljusstimuli orsakar interferens i mörkeradapterade elektroretinogram hos hund : en utvärdering av några av European College of Veterinary Ophthalmology´s rekommendationer för elektroretinografi på hund
Electroretinography is an examination method where the function of the retina is objectively assessed. In 2002 the European College of Veterinary Ophthalmology (ECVO) published a proposition to a standard on how to perform ERG examinations, to facilitate comparison of results and to make it possible to repeat examinations.
The purpose of this study was to validate parts of the canine ERG protocol suggested by the ECVO. Our principal aim was to study if there is any interference at the recommended stimulus intervals for dark-adapted rod- and combined rod-/cone responses.
The results show that there is an effect on the a- and b-wave amplitudes when different stimulus intervals are employed. When all examined intervals are pooled, there is an increase in the median b-wave to each consecutive dim, white (rod) stimulus in a series of four.
Närståendes delaktighet inom psykiatrisk slutenvård : Ur ett livsvärldsperspektiv
Today adult patients' relatives are seen as a resource in psychiatric care but few researchers have examined the lived experience of relatives' participation in psychiatric care. The aim of this study was to illuminate how mental health staff and relatives of adult patients experienced the relatives' participation in psychiatric care on hospital ward.The study was guided by a phenomenological approach and a lifeworld perspective. Data were collected through in-deep interviews with ten adult patients' relatives and three group-interviews with ten mental health carers from two hospitals in Sweden.The essence of the lived experience of relatives' participation in psychiatric care in hospital ward is described in the constituents: invitation to participate in psychiatric care; meet the staffs' care; to participate in own or others terms; bring the common everyday world with you; feel burden; participation a trip in time and space. The findings of the study show that the relation between the staff and the relatives are important for the relatives' participation in psychiatric care. The relatives' participation can alter from no participation to a meaningsful participation, from suffering to well-being.This study can help medical staff to understand relatives and their participation in a new way..
