The purpose of this study was to investigate the presence of arterial insufficiency in patients undergoing CABG surgery and whether arterial insufficiency is a risk factor for postoperative wound infections in the harvesting leg. Patients who had CABG surgery were enrolled consecutively. A total of 144 patients participated in the study. During their hospital stay demographic data was recorded, as well as pre-, intra-, and postoperative tests and risk factors. The patients answered a questionnaire regarding postoperative wound infections 30 days after surgery patients answered a questionnaire regarding infections.

AbstractPeople and organizations that network with one another have during the past decades, at a larger extent than before, replaced classical hierarchies. These networks have become increasingly important, as the globalisation has amplified the pressure for focused and flexibleorganizations. There is a risk of restraining the inventiveness of the firm and force customers and suppliers into cooperation by a too great commitment and dedication to the network. There are two sides to every penny, positive and negative aspects of networking.Concerning the negative approach to networking, there is relatively little theory present. The theory is regarded an emerging theory.

Theories about exposure and risk-taking in an everyday environment show a connection between parental strategies, parent-child relationship and exposure on the Internet. In the present study, the Internet is presented as an everyday activity. Negative exposure is seen as an outcome of risk-taking. The purpose of the study was to examine in what way parental strategies together with the parent-child relationship were related to the teenagers? negative experiences on the Internet, which consisted of three categories: 1) Exposure to pornographic sites, 2) Exposure to upsetting and violent material, 3) Digital bullying.

An investigation of the heat impact of laser cutting on the material properties when producing tensile and impact test specimens of different steel types of varying thickness has been performed. The purpose of the thesis project was to provide recommendations regarding how much material that needs to be milled from the laser cut edge before tensile and impact tests. The study has been performed partly by investigating the test specimens by heat camera when the specimens were cut in the laser cutting line and partly by performing hardness tests, investigation by microscopy, and tolerance and roughness measurements and tensile tests of the laser cut material and material produced in the traditional multi operation machine. The results show that the heat affected zone in the thicker materials is greater than previously thought of, and that the currently used recommendation has to be adjusted. The study clearly shows that the thicker the material, the greater the heat affected zone, independently of the steel type, since the thicker material takes longer time to cut.

The purpose of this study was to investigate produced laser data from the new national height model's airborne laser scanning in Sweden, what quality it has and whether it can be used for forest management planning. From airborne laser scanning one can obtain information on forest variables such as tree species, height, diameter and basal area. Norra skogsägarna is the principal employer of this project and they wanted know to the quality of the laser data which needs to cope with their standards. If the laser data the quality required it can replace some of the operations performed by field planners. To examine the quality of the produced laser data a control tax assessment has been performed in 30 forest departments. This was done in an objective manner.

En bostad kan ses som en investering och finansieras oftast med ett bostadsslån från en bank. Finansinspektionen som fungerar som ett tillsynsorgan till bankverksamheterna har agerat mot en osund kredithantering med hjälp av införandet av ett bolånetak. Tidigare finansiella kriser har visat på svårigheterna att i förväg föreställa sig effekterna av framtida osäkerheter. Vid ett bostadslån kommer kreditgivaren och kredittagaren behöva resonera kring framtida osäkerhet som medföljer skuldsättningen. En ökad skuldsättning i förhållande till disponibel inkomst för varje enskild låntagare skulle innebära en ökad risk för bankens stabilitet.

In this final thesis, an existing method for analysis of chlorophenols (CP) in bottom sediments has been updated and adjusted for analysis of chlorophenols in soil. The covalent bonds between the chlorophenols and the soil matrix were broken through basic hydrolysis and the chlorophenols were then separated from the water phase through addition of sulphuric acid followed by ether extraction. The chromatography was improved through extractive acetylation of the chlorophenols.The updated method was then applied on soil samples from a contaminated area (a former sawmill in Hyttsjö, Östergötland, Sweden).The analyse was preformed by GC/MS with respect to 2-MonoCP, 4-MonoCP, 2,4-DiCP, 2,6-DiCP, 2,4,6-TriCP, 2,3,4,6-TetraCP and pentachlorophenol (PCP).Contamination of chlorophenols in nature can be explained by the former use of wood preservative chemicals based on chlorophenols. In the 1960s and the 1970s these chemicals were used in Sweden, but due to their toxicity they were banned by the Swedish government in 1978.In Hyttsjö a pentachlorophenol-based product named Santobrite was used for several years. The concentration of PCP in the soil samples from Hyttsjö varied from 0.2->1.8 ng/mg dry substance.

Studien undersöker potentiella fördelar för företag att arbeta med och redovisa om CSR, Corporate Social Responsibility, i termer av minskade avkastningskrav från investerare. Med utgångspunkt i teorier om informationsasymmetri och stakeholderteori testar vi om svenska börsnoterade företag som arbetar med och redovisar om CSR är förknippade med lägre risk och således också lägre avkastningskrav från investerare. Våra resultat visar att en separat publicerad CSR-redovisning eller hur företagen betygssätts för sitt CSR-arbete inte har någon påverkan på investerares avkastningskrav. Dock finner vi att avkastningskrav på företag som redovisar om och/eller vars arbete med CSR-frågor värderas högt blir lägre ju fler sidor de publicerar om CSR i en separat rapport..

Sedan år 2005 är börsnoterade företag i Sverige tvingade att följa internationella redovisningsregler utfärdade av IASB. Det innebär att nya standarder gällande värdering av tillgångar ska tillämpas. De nya värderingsreglerna har utvecklats för att redovisningen ska innehålla relevant finansiell information. Det har medfört att förvaltningsfastigheter, som definieras i IAS 40, kan värderas till verkligt värde. Dock är verkligt värde regleringen relativt otydlig och kan ge upphov till eventuell övervärdering av tillgångar.

The environment has become an important part in people´s lives, and in today´s society stakeholders demands have increased upon companies when it comes to sustainability reports. How these sustainability reports are designed depends on whom it?s for, laws and regulations, and the companies own norms and values. The purpose of sustainability reports is to measure, monitor and compare a company´s enviromental impact. It?s not only about integrating economics, but also enviromental and social standards together to get both financial and competitive advantages.Sustainable Value method is a new model and is the first real method that can be used to evaluate a company´s resources, both financial, social and enviromental to a sustainable value.This model is used to compare the resource efficiency between companies.In this thesis, a documentary study with an experimental approach has been made.Sustainability reports from six selected companies (in the engineering and forestry sector) have been investigated with respect to their accounting for carbon dioxide, and an experiment using the method ?Sustainable Value Approach? was subsequently performed.

SammanfattningSyfte och frågeställningarSyftet med studien var att undersöka vad elever i årskurs sex har för föreställningar om ämnet idrott och hälsa, om ämnets innehåll och omständigheter kring det.Hur ser föreställningarna om idrott och hälsa-läraren ut?Hur ser föreställningarna om ämnets innehåll och kunskapskrav ut?Hur ser elevernas föreställningar om begreppet hälsa ut?Hur ser föreställningarna om elevbeteendet under lektionerna ut?MetodFör att ta reda på detta gjorde jag djupgående intervjuer med tio elever som går i årskurs sex på en sex till nioskola. Studien är gjord ur barns perspektiv med en fenomenologisk ansats.ResultatStudiens resultat är att en idrott och hälsa-lärare är för eleverna en vuxen som tar ansvar genom att inte tillåta dåligt beteende på lektionerna, en coach som peppar dem och en atlet som kan visa övningar och föregå med gott exempel.

In November 2007 the countries around the Baltic Sea signed the Baltic Sea Action Plan (BSAP). The action plan was an initiative from HELCOM due to the environmental status in the Baltic Sea. The action plan implemented a new approach with measures targeting the whole ecosystem. Eutrophication, hazardous substances, biodiversity and maritime activities constituted the main segments. The parties were to establish national implementation plans to fulfil the BSAP goals, which shall lead to good environmental status in the Baltic Sea by 2021.  The aim of this thesis is to investigate the points in common regarding conceptions of eutrophication in the Baltic Sea between the management, the science, the media and the public.

This report discusses the IT archetypes "governance strategy" and how it could be linked to the IT benefits at the company. The study is based on IT investments that have taken place in ten banks operating in Sweden today, where the reality was modeled on the basis of a questionnaire survey and an additional interview. The aim was to examine whether it is possible to find any correlation between the governance in the banks and obtained benefits for an IT investments.While the competition is intensifying in most companies there is a greater demand for efficiency in IT. The need for IT solutions is greater than ever and the number of IT investments is increasing significantly in most workplaces today, especially on banks. But even if the investments are increasing in numbers it does not necessarily mean that all types of investments are effective and beneficial to the company.

Vaccinology is an ever expanding field. As a member of the veterinary staff it is important to stay up to date with the continuous new scientific data and recommendations that affect the care that our companion animals receive at the veterinary clinic. This paper presents adverse vaccination reactions, their cause, risk factors and suggestions how we can minimize the risk of adverse vaccine events in dogs. Dog owners in Sweden were allowed to answer a questionnaire about adverse events following vaccination. Lethargy, edema and pruritus were among the most frequently seen adverse effects.
