Risken för kolorektal cancer i förhållande till kostmönster, fysisk aktivitet och BMI i sydöstra Sverige : Analys av data från en fall-kontrollstudie
Bakgrund: Tidigare studier har identifierat flera riskfaktorer, såsom kost, fysisk aktivitet och BMI, gällande kolorektal cancer. Att analysera kost utifrån kostmönster istället för enskilda livsmedel har visat sig vara effektivt för att undersöka risker för kolorektal cancer. Datamaterial samlades in med hjälp av en fall-kontroll studie med 257 fall och 805 kontroller.Syfte: Identifiera faktorer som ger en höjd eller sänkt risk för kolorektal cancer utifrån områdena kost, fysisk aktivitet och BMI.Metod: Faktoranalys användes för att upptäcka kostmönster. Logistisk regression användes för att skatta oddskvoter och 95 % konfidensintervall.Resultat: Tio stycken kostmönster erhölls från faktoranalysen. Kostmönstren ?Läsk, juice och mjölkprodukter? (OR=1,288; ORQ4=2,159), ?Te, men inte kaffe?(OR=1,228; ORQ3=1,891; ORQ4=1,668) och ?Fågel, rött kött och fisk?( ORQ4=1,724) gav alla en ökad risk.
Implied Dividends and Equity Returns
This paper studies the option market?s implied dividend as a predictor of future equity market returns. We introduce this variable in the simple total return framework and discuss some complications of using it as a proxy for the expected dividend. We construct some regressions using the price-dividend ratio and the implied dividend growth, and test them on six years worth of data on the EURO STOXX 50-index. The main result is that implied dividend growth exhibits some forecastability over two-year horizons, but that the dataset is too short to draw any definitive conclusions about long-horizon forecastability.
Fukt i byggnadsmaterial : Hur man förebygger fuktskador vid materialhantering på byggarbetsplatsen
Byggsektorn har fortfarande svårigheter med att hantera fuktproblematiken. Vi har valt att fokusera på hanteringen av material i produktion. Den informationssamling vi utfört ligger till grund för vår analys och slutsats. Vi har intervjuat flera olika entreprenörer från byggbranschen för att ge oss en helhetssyn av fuktsäkerheten ute på byggarbetsplatserna. Studien påvisar att det råder brister både på beställar- och entreprenörssidan. Vi ser att det finns potential för förbättring när det så krävs.

HMS Networks AB develops, produces and sells communication technology for industrial automation. The product handles communication between a variety of protocols. The product treated in this project is an Anybus X-gateway Modbus-TCP Master/Client and this module is currently configured from a web-based interface. In doing so, the flexibility for handling protocols is limited to what the company chooses to add to the interface. Therefore the company had a request that the flexibility should be extended using a script language.
Riskbilder och kontroll av ungas IKT-användning: En fallstudie
The use of Internet by children and teenagers has become a special field of interest. Certain risks are associated with young peoples use of this media and national and international measures have been taken to assess and counter these risks.Library and informationscience have approached the subject of risks by looking at different software´s, so called Internet filters, that is used to control and censor the access to Internet based resources. In the USA, where public services and institutions that provide Internet resources to children and youth have started to require censorship of the Internet, a debate has arisen concerning the use of so called Internet filters.The theoretical basis of this master´s thesis is related to the conception of risk, gender and childhood. The focus of the paper lies on young peoples use of information and communication technology (ICT) and how risks associated with young peoples use of the Internet is constructed by different parties involved in supplying Internet resources. By means of a case study at a primary school in Skåne and at the company Netscan in Malmö.
Osäkerheten i ombyggnationsprojekt : Case Study av ombyggnation av Praktikertjänst huvudkontor
The real estate industry is a sector where the companies generally have a capital structure which is high leveraged. The financing? with the related terms ? is therefore specifically of high importance for the companies in the sector. Traditionally, the way of obtain financing is by borrowing from the bank. Lately, due to new bank regulations, the banks have become more restrictive in their lending which have lead to a growth of other financing alternatives.
Termografisk undersökning med samtidig analys av rektaltemperatur, hjärtfrekvens, psykiska reaktioner och specifika blodparametrar av häst som behandlats med vibrationsboxen Vitafloor :
A number of studies in human medicine has documented positive effects of whole
body vibration treatment in humans. The Vitafloor system, witch is based on
treatment of horses with vibration, has the purpose to be used in training of
healthy horses and as rehabilitation for horses with injuries in their musculosceletal
system.
The purpose of this study was to analyse what happens with a clinically healthy
horse during treatment with Vitafloor. The methods used is mainly thermography
before and after treatment, but also blood samples, measurement of rectal
temperature, heart rate, clinical examination and observation of psychic reactions
has been done.
Statistic significant changes in skin temperature in hoofs and fetlocks of front legs
has been observed after treatment with Vitafloor. Analyzing of the blood samples
showed a tendency for decrease in Kalium, and two of the horses had changes in
CK. No negative effect has been observed with the treatment of horses with
Vitafloor, and the horses seems to like the treatment.

Vakuumbrytare i småskaliga vattenkraftstationer
This master thesis has been performed at Vattenfall Power Consultant in Gothenburg and Trollhättan for Vattenfall Vattenkraft. In this report vacuum circuit breaker in small-scale hydropower stations with the rated power 4 MVA and below has been studied. Models of the stations are modeled and analyzed in PSCAD/EMTDC to study the high voltage transients that are created after current chopping with vacuum circuit breaker. Vacuum circuit breaker may chop the current before it reaches zero value, which means that high voltage transients can be created. The equipment of the stations can be destroyed by high voltage transients.The purpose of this thesis is to examine the use of vacuum circuit breaker in small-scale hydropower stations and the risk for high voltage transients from current chopping.According to the results there is a risk of high voltage transients after current chopping with small synchronous generators in stations with the operating voltages 0.4 kV and 3.6 kV.
Kan behandling av insomni förbättra komorbid ångest och depression?

Förstudie för kvalitetssäkringav glidande förband vid Hissmoforsvattenkraftsstation : -Specifikt för aggregat G6 och G7
Jämtkraft AB which is a power production company in Sweden has bought two newhydro power units to their station in Hissmofors. The two new generators are using aconcept with sliding stator feet to handle the thermal expansion.The concept with sliding stator feet on hydro electric generators has not beenworking satisfactory on many hydro power stations in Sweden and has caused a lot ofcosts due to long downtimes.The new station in Hissmofors is very important for Jämtkraft AB, and therefore theywant to know how to make sure that the sliding stator feet are working as theyshould. According to theories and a simplified model of the generator the stator feetdisplacement should be around 1 -1,6 mm.The generators are delivered with a surveillance system that will measure thedisplacement of the sliding stator feet. The signal from the system isn?t accessible forJämtkraft AB but it will alarm when the sliding stator feet are malfunctioning.To secure the function of the sliding feet a logger for the surveillance system or adifferent measurement system must be used; if both systems are used Jämtkraft cansecure the function of the surveillance system..
EKONOMISTYRNING AV BUTIKSVERKSAMHET: ? en fallstudie av modeföretaget ?Alfa?
The aim of this thesis is to examine how salesperson control can be exercised in a retail store environment. A case study has been performed on a Swedish fashion company emphasizing the relationship between the company?s upper level management and their retail store operations in order to describe, analyze and classify the prevailing management control mechanisms. The paper presents an agency theoretical approach to the relationship applying behavior- and outcome based control theory, performance measurement theory and incentives theory in order to give a comprehensive image of the control system. The main finding is that the company?s management control system as applied to the sales force in its retail stores can be categorized as mainly behavior-based despite several explicit outcome-based features..
