When cylinders for motor saws are manufactured there are high demands on the cylinders strength and wearing qualities. Aluminum is a material with low density and is used by Husqvarna AB for their motor saw cylinders. The aluminum is strengthening with nickel that is attached to the cylinders through electrolysis. When aluminum is in contact with oxygen a film of oxide is formed. To eliminate the oxide and to prevent formation of new oxide zinc is used.

The composition of the board of directors and Corporate Social Responsibility (CSR) are two widely researched subject and discussed by the media. This study aims to examine the impact of the board of directors' composition on CSR performance among the largest companies listed on Nasdaq OMX stock exchange 2008 in Stockholm, Sweden. A linear regression analysis is applied to investigate the relationship and evidence is found that board attributes have an effect on CSR performance. Among these; the size of the board, outside directors and employee representatives all have a positive impact on environmental performance. Furthermore; female, outside directors and employee representatives have a positive impact on social performance.

Sub-lethal doses of neonicotinoids have been shown to negatively impact the health of honeybees. However, most studies to date have exposed bees only artificially to these pesticides under laboratory conditions. There have been just a few well designed and replicated studies of the impacts of realistic neonicotinoid exposure on honeybees foraging under field conditions. In order to close this knowledge gap, and to test the influence of the neonicotinoid clothianidin on honeybees, we used a study system of 16 paired, spatially separated (>4 km) spring oilseed rape fields in the south of Sweden. The fields were paired according to land use, the surrounding landscape and geographical proximity, using GIS.

This report is a joint venture with SCA Skog AB in the Jämtland forest management area. The company is a major player in the timber market in northern Sweden, and also a large business globally with offices in over 100 countries. The purpose of the study was to find out how timber suppliers want feedback/follow-up after completion of timber business. To determine this, a questionnaire survey was sent out to 75 landowners who supplied the wood for the company during the past year. The questionnaire consisted of a total of 15 questions with the opportunity to comment on certain issues.

The purpose of this Master?s thesis is to examine similarities and differences in qualitative experiences between formal and informal reading groups from the participants? point of view. The empirical data was acquired from interviews with nine reading group participants, of whom four of them participated in formal reading groups and five in informal reading groups. To analyze the empirical data, Louise M. Rosenblatt?s theory concerning reading and a method concerning reading groups by Immi Lundin were used.

The purpose was to examine how the pre-schools used the public libraries in two Swedishtowns. We also examined if and how the pre-schools and the public libraries were coopera­ting.Literature showed that it is possible to stimulate children's language development and this is a duty for pre-schools and public libraries. We sent an inquiry to all pre-schools divisions in both towns. We interviewed two librarians. Our results showed that the pre-schools did use the libraries to a great extent but they didn't cooperate with the libraries in the sense that they had elaborated agreements.

This paper aims to derive the Black-Scholes equation for readers without advanced knowledge in finance and mathematics. To succeed, this paper contains a theoretical chapter in which concepts such as options, interest rate, differential equations and stochastic variable are explained. This paper also presents the theory of stochastic processes such as the Wiener process and Ito process. In the chapter on the Black-Scholes model the Ito process is used to describe price of shares and with the help of Ito's lemma Black-Scholes equation can be derived. In the paper, assumptions are listed that apply to the Black-Scholes model and then uses the Black-Scholes equation to calculate the price of a European call option.

This thesis deal with tick burden on roe deer (Capreolus capreolus) fawns, in relation to age, weight, hind foot length, and as well as to vegetation and habitat on bed sites. Roe deer fawns (N = 25) were captured from May 27 to June 27. Samples of ticks were collected and tick burden were estimated. Of all sampled ticks the nymphs and adults were Ixodes ricinus, while the larvae were not identified. 4.4 % of the sampled ticks were larvae, 55.0 % nymphs, 26.8 % adult females, and 13.8 % adult males.

Operators and Internet service providers invest in broadband to be able to deliver new services that require higher data transmission rate. A way to make this possible is to use ADSL, Asymmetric Digital Subscriber Line, as the access technology. To be able to handle this technology, the service providers should do a pre-qualification. Methods and tools are needed to analyze the local copper lines and decide if these qualify for ADSL with respect to service availability and possible bandwidth through the lines. This report brings up some methods for pre-qualification of ADSL, the important quality parameters and how to gather them from the available services today.

Syftet med uppsatsen är att diskutera det så kallade equity premium puzzle. Jaganalyserar teoretiskt den intertemporala konsumtionsbaserade CAPM (C-CAPM),sammanställer en del av litteraturdiskussionen som finns på området samt empiriskttestar C-CAPM på svensk data. Fenomenet equity premium puzzle innebär attöveravkastningen på aktier är så stor att det inte stämmer med den ekonomiska teorin.Enligt teorin beror C-CAPMs riskpremie på kovariansen mellan konsumtionen ochaktieavkastningen. Litteraturen visar att forskare inte har lyckats förklara equitypremium puzzle genom att ändra antagandena i grundmodellen. Den empiriskaundersökningen visar att equity premium puzzle även uppkommer på svensk data..

Prior studies have shown that earnings management can be used either to inform or to mislead investors about the future performance of a company. However, few studies have examined the impact of earnings management on forecasting return on equity (ROE). The aim of this thesis is to investigate whether the ability to forecast next year's ROE is improved when taking earnings management, measured as discretionary accruals, into account. This is examined by comparing a forecast model that takes the magnitude of discretionary accruals into consideration with a model that does not. The study is based on companies that were listed on the Stockholm Stock Exchange during 2002-2012.

Previous work by researchers as Eugene F. Fama and Kenneth R. French, show that average return on stocks are related to a firms characteristics like size and book-to-market ratio. These kinds of patterns in average return is not explained by The Capital Asset Pricing Model (CAPM), and are therefore seen as anomalies. Fama and French have proposed a three-factor model, which captures patterns observed in U.S average returns associated with size and value.

This degree project is a realization of a strategy for collaboration between an industrial designer and employed workmen of a producing company. The collaboration aims to engage everyone involved in the co-authorship of a products design and manufacturing history. The realization has taken place in an open dialogue where the designer no longer owns the design process by himself. The project has been carried out in cooperation with the company Iris Hantverk. The company is owned by the Swedish body for visually impaired and has their main production facility in Stockholm.
