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.

This paper was part of the ongoing cooperation between the Swedish Civil Aviation Authority and the Department of Psychology at Lund University. The purpose of this study was to develop a self-report measure regarding human factors, for the air traffic controllers to fill out before they start their working shift. This in order to aid the team leaders in their judgment regarding the air traffic controller's ability to perform at the right safety level. The self-report measure would also serve as an aid for the air traffic controllers who have a responsibility regarding their own performance. If successful this self-report measure would make it easier for the air traffic controllers to be alert regarding certain factors that can have a large impact on their performance.

The aim of this study is to fill the gap in mathematics education research concerning the relationship between identity and positioning in mathematical collaboration in groups. This study elaborates on the relationship between how pupils see themselves as math students in sixth grade, how they show their identities as math students, in contrast to how they position themselves reflexively in group collaboration while engaging in mathematical problem solving. The theoretical concepts linked to this study are discourse, identity and positioning. Discourse is used to describe and form the setting and context of the study. Identity is seen as a transient and elusive concept formed by the students own perceptions of self through narratives.

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.

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.

The purpose with this essay is to illustrate the problematical mother-daughterrelation in Mar-gareta Garpes drama/play ?To Julia? through a psychoanalytic and philosophical perspective. To get a deeper understanding for the relations between mother and daughter, and the kind of motherhood that Gloria is practising in the play I have used a hermeneutic method in search for answers to the questions: Why does Gloria take a position as a so called friend or sister in the interaction with her daughter Julia? Why is not mother Gloria capable to be mature, caring and nursing in the interaction with Julia? Through Gloria Margareta Garpe is giving me possible answers: Gloria is still seeing herself as a rejected and lonely child. The role of the daughter Julia in her mother?s life is to fill an empty space that was created in Gloria?s adolescence when she experienced the same feelings as Julia in present time in the play.

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..

The debate about women and equality is a very burning issue in the Swedish society today. There are a lot of articles, TV-programs, books and web sites treating the position of female leaders today. There are also a lot of myths strongly attached to our minds hindering the equalization process between men and women.The main purpose of our study was to look at women as leaders and identify potential tendencies in businesses sectors dominated by mainly men or women. We also wanted to find out whether leadership behavior is more or less oriented towards relations- or task in any of the chosen sectors. It was even in our interest to see if our chosen respondents supported the myths in our society about male and female qualities.We interviewed 20 women in four different sectors, two dominated by men (Computer/It, Transport) and two dominated by women (School, Healthcare).

The primary intention of this paper was to visually compare film trailers without considering semantic information, through use of a self-developed Matlab program, resembling that of human perception. Circa 150 people participated in an online survey where they were shown two film trailers and asked to rate their visual similarities. The result from the program was weighted against the survey results in such a way that the weights corresponded to a 75% accuracy between the program?s and the participant?s (for participants with prior experience in the field of photography and/or film) comparisons.How accurate can we compare still images from film trailers, and find similar trailers for the human viewer, by analyzing saturation, color tone, contrast and lightness with a self-developed Matlab program..
