Background: Resources that are hard to put a value on and cannot be classified as assets in the balance sheet as well as the development towards the information society has led to an increasing need and use for voluntary information in the annual reports. The increase of voluntary information can foremost be seen in the field of human resources.Purpose: The purpose of this thesis is to describe the development of voluntary information about human resources in the annual report of a number of Swedish quoted companies. The purpose is also to see if there is a difference in the development between manufacturing companies and service companies.Method: Six manufacturing companies and six service companies were chosen from the Stockholm exchange A-list. Using both a qualitative and quantitative research method the annual reports of the chosencompanies were studied for the years 1995, 1997, 1999, 2001, and 2003. A model consisting of seven categories; health, diversity, recruitment, staff turnover and comfort, benefits and motivation, education and competence development, was developed to clarify were the development took place.Conclusions: After finishing the study one can tell that the amount of voluntary information about human resources in the annual report has increased even though the percentage share of the total annual report only has increased appreciably for manufacturing companies.

The automotive market is currently undergoing a historical change where stricter emission legislations and ever increasing fuel costs have intensified the search for effective alternatives to the conventional internal combustion engine, which has resulted in a substantial trend towards electrification of powertrains. Storage of electrical energy is the fundamental component in this technology where the lithium-ion batteries are currently considered as the most appropriate solution. Lithium-ion batteries, however, as other types of batteries, can only be used efficiently and durably within a specific temperature range.This Master thesis has been carried out in collaboration with Electroengine in Sweden AB, situated in Uppsala, which has an ongoing project regarding development of a modular battery system for electric powertrains. The project is at a stage where an initial prototype has been developed which provides the foundation for this thesis. The study has addressed the battery system performance from a thermal perspective, in order to validate the ability of the system to create a thermally serviceable environment for the lithium-ion battery cells.

Det konstrueras i stor utsträckning bristfälliga detaljlösningar på byggnader i dagsläget. Den bärande stommen i konstruktionen prioriteras ofta medan det inte ägnas lika mycket fokus åt att tillgodose de byggnadsfysiska aspekterna. Anledningen till de bristfälliga detaljerna är även att den som utför arbetet saknar rätt kunskap och tid. För att skapa en förbättring behövs ett hjälpmedel!Kunskap och erfarenhet om hur bra detaljer skapas finns redan i företag, svårigheten är dock att sprida kunskapen till de som är i behov av den.Målet med denna rapport är att skapa en metodik som blir startskottet för ett omfattande arbete kring framtagandet av ett detaljbibliotek, vars syfte är att sprida byggnadsfysiska kunskaper inom företaget och inspirera konstruktörer till att konstruera bra detaljlösningar. Biblioteket ska innehålla byggnadsfysiskt utredda detaljlösningar som analyserats enligt den utarbetade metodiken.

Syfte: Syftet med denna studie var att ja?mfo?ra den initiala komforten mellan sfa?riska och asfa?riska stabila linser da? uppfattningen har varit att asfa?riska linser (med sin mer fo?ljsamma passform) borde vara bekva?mare.Metoder: Studien omfattade 30 deltagare med en medela?lder pa? 26 a?r. Med hja?lp av topografens (Topcon CA-100) kontaktlinstillpassningsprogramvara valdes en sfa?risk A- design lins (fra?n Nordiska Lins) och en asfa?risk A90 lins (fra?n Expert Optik, Sverige) ut med passande parametrar. Linserna sattes i vardera o?ga utan att fo?rso?kspersonen visste vilken lins som var vilken.

Stump biomass is energy rich and stump harvesting for use as fuel become more and more interesting in Sweden. Swedish Forest Agency (2009) has estimated that stump harvesting in Sweden would respond to an annual energy supply of 57 TWh/year. However, stump has not been recognized as a bioenergy resource in Sweden. Suitable methods for pre-treatment of stump are probably of great importance to make it accepted as fuel. It is therefore rewarding to carry out an investigation in this area for stump. This report represents results from a diploma project, which was aimed to develop a fixed bed reactor for experimental study of biomass torrefaction, followed by TG analysis and kinetic modelling employing Ozawa method and different kinetic models including one-step and three-pseudo-component models.

Introduction: A big part of the patients that recently has gone through operation at surgical units experiences pain in different scales after their operation. Untreated postoperative pain has been proved in different studies to increase to risk medical complications, longer rehabilitation, more days at the hospital and higher expenses for the hospital. One of the nurses? main tasks is to notice and relieve the pain of the patients. To engage the patients more in the medical process and make the nurses´ work more person-centered could make an impact on the postoperative pain and contribute to a better pain relief.

This master thesis was carried out for Saab Avitronics, a business unit of Saab ABactive in electronic systems for military aircrafts. Reliability and weight are of crucialimportance in this environment. To improve reliability and lower the weight graphitemay be used for electronics cooling. Graphite is an anisotropic material and hasthereof high thermal conductivity in two directions (in-plane) and a relatively lowconductivity in the third direction (through thickness).The purpose of this thesis was to investigate if graphite is an adequate thermalconductor to use in PCB carriers. The carriers support and cool the PCB by divertingthe heat dissipation from the PCB components to the edge.

Glass has sophisticated front properties and are used as facades in high buildings. During cold periods, these glass facades could cause thermal discomfort, due to cold downdraught. Cold downdraught can be countered by placing heaters under glass surfaces. Nowadays technology offers highly insulating windows, which is why there is an interest to investigate the indoor climate with only underfloor heating. The research in this area is limited, and few empirical methods are available.

In December 2008 the municipal council in Nybro, decided that the municipality shouldreduce the budget for food service. The budget should be reduced by 2 100 000 SEK.They decided that the children- and education committee, and the care committee would haveto lower their budget with 1 264 000 SEK respectively 636 000 SEK. The change have to bedone under two years, 60 % should be done under 2009 and 40 % under 2010.As a result of the decision, many kitchens have to become kitchens that only serve food, notcook it. This will result in preschool staff and nursing staff take over some of the tasks fromthe kitchen staff. The municipal council also decided that entrepreneurs could take over one(later two) cooking areas.A kitchen that serves food means that there isn?t any cooking involved.

This literature review describes organic pig production in Sweden, its advantages and disadvantages, but also how its problems can be reduced or solved. Organic pigs have the possibility to a more natural behaviour than conventional pigs. With outdoor pigs comes problems, especially during wintertime, concerning water and feed supply, thermal environment and supervision. Parasites and leakage of plant nutrients are other difficulties that comes with outdoor pigs. All problems and difficulties can be reduced or put right through correct management.

The United States is one of few Western nations that administers capital punishment to their condemned criminals. Texas has executed the most inmates of any state in the U.S. This prompted questions about the psychological characteristics of death row inmates. The purpose of this essay is to widen the perspective on inmates serving capital sentences by analyzing their final statements. The focus of this essay was centered on acute anxiety of death among inmates, visible in their final statements, as a result of an accelerated process of dying.

The purpose of this study is to survey and evaluate if the individual contrast sensitivity and preferences for horizontal and vertical lighting level correspond to the values that standard SS-EN 12464-1 recommends for the workplace- and surrounding light levels.This study examines if lighting should be adapted after the individuals? need or if a general value can be found that will cover every individuals? need for a workplace and surrounding light level. This study also examines if parameters like sex, age and/or glasses/lenses have an effect on the amount of lighting that the test subjects need. Lastly we compared the values concerning the relationship between workplace- and surrounding light levels with standard SS-EN 12464-1?s recommendations.The study is carried out with an experimental design that surveys 220 test subjects who were chosen by a selection of convenience.

To fulfill the climate target that EU and the Swedish government have decided to apply, it becomes increasingly important that the energy efficiency of existing buildings and making new buildings energy efficient as possible. Of Sweden?s total energy consumption in 2011 was 40% used by residential and service. Of the 40% of the energy consumption was 60% used for heating and domestic hot water. A report from year 2012 shows that one reason why the heating volume is so great could be due to underestimating on the energy consumption for the heating in the planning of the building.

AbstractThe purpose of project is to study the possibility for Borås Energy & Environment to build and run a commercial ethanol production facility in Borås. The project also studies the technology for the production of ethanol using renewable energy, e.g. lignocelluloses with focus on two processes, svag-syra hydrolyse and enzymatic hydrolyse. The technology of the process is based of hydrolysation of biomass (hemicelluloses and cellulose) to sugar and extract it to ethanol. These two techniques will compare with each other to determine which of them that it?s more suitable for ethanol production.
