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 main purpose of this thesis is to analyze laws that completely prohibit abortion through a legal philosophical perspective. To demonstrate that abortion blanket bans cannot be seen as legally legitimate, the author has completed a literature study where she uses Robert Alexy?s ?Concept of Law? to analyze abortion laws both in general, and in Nicaragua in particular.Based upon Alexy?s ?Concept of Law? the author has identified three relevant key elements ? social efficacy, the argument from injustice and correctness of content - which she uses in her analysis. In order to apply these three elements on the total abortion ban, she then uses four different analysis tools - feminist theory, Human Rights, deontology analysis and right analysis. This has enabled a thorough analysis of the total ban on abortion that has demonstrates that such laws cannot be considered legitimate.By highlighting the human rights violations the law entails, one can conclude that the law has a social impact.

Bakgrund Idag diskuteras det mycket kring vilken roll sockerkonsumtionen kan spela gällande de ökande hälsoproblemen i samhället. På senare tid har det flytande sockret lyfts fram som en av de stora bovarna i dramat och forskning visar på att läsk bestående oberoende av vanligt socker eller artificiellt socker, kan påverka hälsan negativt. Syfte Syftet med undersökningen var att granska ungdomars läskkonsumtion samt att ta reda på deras motiv till varför de föredrar att dricka vanlig läsk respektive lightläsk. Det är även av intresse att undersöka eventuella könsskillnader. Metod Undersökningen har gjorts med hjälp av en enkätundersökning med intention att beskriva ungdomars läskkonsumtion. Valet av undersökningsmetod syftade till att ge bredd åt undersökningen.

This master thesis has been a pilot study preceding a forthcoming project of a larger scale with the long term objective to separate the direct effect of added nitrogen on soil processes from indirect effects via trees. The aim of this study has been to investigate the allocation of nitrogen following direct injection of liquid solutions into the xylem of 40 year old Norway spruce. The field site is located at Flakaliden (64°07?N, 19°27?E), approximately 60 km northwest of Umeå, Sweden. A total of 18 trees were selected for treatment, equally divided between three treatments, potassium nitrate, glutamine and water (control).

Research regarding the maintenance of the Sami language shows that the Swedish society has a big influence on the development of the Sami identity and also the maintenance of the Sami language. The assimilation of the Sami language and the traditional Sami religion was forced mainly by the Swedish education form and the Swedish church. In modern times many different forms of Sami identities have been developed due to the scattering of the Sami people, and also because of the urbanization of the Swedish society. The Sami nature religion is still alive in the Sami group, thanks to the mythological stories told and preserved by their oral  tradition. The purpose of this assignment was to make research of how the Sami identity is being presented in three current Swedish books.

With the help of large amount of archive material I have examined how Gustavsberg in Värmdö were affected by the great labor migration in Gustavsberg porcelain factory during the period 1869-1924. I have chosen to investigate how the municipality dealt with the poverty relief issue out of the labour immigration perspective. To my surprise I found out that Värmdö was not responsible for Gustavsberg in the poverty issue. The workers belonged to the factory, which had a relatively well-developed system of poverty relief in place. This is not to say that the workers received any support from the factory to any great extent.

Scandinavian Biogas is involved in the planning of a combined ethanol and biogas factory in Karlskoga, Sweden. Besides biogas and ethanol large amounts of digester residues will be produced, about 450 000 liquid tonnes residue (~7,3 % Dry Substance( DS)). The objective of this thesis was to investigate possible uses of the residue from the biogas production process ScandgasEthanol developed by Scandinavian Biogas, and to derive a methodological approach how to evaluate and compare handling systems. Three systems where proposed and compared in this thesis; spreading of the untreated residue as fertilizer (system 1), dewatering to a higher DS content to reduce transportation before spreading as fertilizer (system 2) and production of a solid fuel by dewatering and drying the residue (system 3). The general conditions for the proposed systems were investigated in terms of practical viability, economical aspects, environmental impact and energy inputs/outputs.

The aim of this study is to examine the media coverage of gender-neutral marriage from an intersectional perspective ? with particular regard to gender, sexual orientation and religion. By focusing on the spokespeople who appears in the articles we have made an attempt to answer questions regarding who was heard in the debate on gender-neutral marriage and how the homosexual couples are portrayed in relation to the above criteria.The collected material consists of 89 articles, published in 2009, in Swedish newspapers which have been analysed by using quantitative content analysis. Ten articles have also been selected for a critical discourse analysis based on Norman Fairclough?s approach.

Important issues for the local authorities are what to do with the sludge produced insewagetreatment plants. The tax for landfill leads to higher costs with 250 SEK/ton. On the 31December 2004 it will be forbidden to landfill sludge.In Sweden the yearly production of sludge is 240 000 tons, counted as DS. The phosphorouscontent is 3 % in sludge. The total yearly production of sludge gives 6000 tons of phosphorous.

In May 1675, the local court in the northern Swedish parish of Nordingrå, which had approximately 1,000 inhabitants, held a preliminary investigation on 113 persons accused of witch-craft and superstition. For the majority of the 113, the main accusation was to have travelled to Blåkulla, a place where witches according to Swedish folklore participated in satanic festivities and rites led by the Devil himself. The preliminary investigation was held at the request of The Royal Witch-craft Commission. Nordingrå belonged to the province of Ångermanland, one of the Swedish provinces with the highest number of witch trials in the 1670s. The trials in Nordingrå have, more or less never been examined before, mainly due to the fact that no sentences or penalties were ever imposed.The purpose of this paper is to examine social relations and social conflicts in Nordingrå with the records from the witch trial 1675 as the primary source.

Although women have had access to colleges and universities in Sweden for quite some timeand the share of women at the undergraduate level has been high for many years (40% by thelate 1950:s, nowadays women are a majority at that level), still the share of women professorsis low. This paper will study some researchers? view on how a professor should be, and alsohow they relate themselves to that ideal. The method used is qualitative interviews, whichhave then been analysed by discourse analysis. The paper also contains a discussion on thehistory of the universities from the Middle Ages and forward, to show how the impact of thathistorical legacy affects universities today.Eight respondents were interviewed, four women and four men.

Pulp- and papermills expend vast amounts of water in order to produce pulp, paper and cardboard. Hence, they alsocreate vast amounts of waste water which has to be cleaned before it can be released into the receiving body of water. Insuch a wastewater treatment plant, tremendous amounts of energy are expended by the aeration in the biologicalcleaning process. This aeration is necessary to supply the microorganisms that shall decompose organic material withoxygen, which they need for their metabolism. The transfer of oxygen from the gas phase to the liquid phase isprimarily inhibited by surface-active substances in the waste water like resin acids or fatty acids.

Syfte med uppsatsen har varit att underso?ka fa?rgens och gestikens pa?verkan pa? altarska?pets iscensa?ttning av bera?ttelserna och da?rmed a?ven budskapet. Uppsatsen har ett bildsemiotiskt perspektiv som en utga?ngspunkt. Materialet fo?r underso?kningen a?r ett flandriskt altarska?p fra?n Ska?nela kyrka som finns idag i Uppsala domkyrka.

Syftet med denna uppsats är att bättre förstå om och i så fall på vilket sätt kyrkans ledning tänker sig att deras personliga tro hade betydelse när de fattade beslut för utformningen av S:ta Claras verksamhet. Fyra beslutsområden har studerats. Två handlade om bön och två om val av plats för det utåtriktade sociala arbetet. Studien har genomförts utifrån elva kvalitativa intervjuer med individer som deltagit i beslutsfattandet inom de undersökta beslutsområdena. Resultaten från intervjuerna har analyserats med hjälp av en handlingsteori och två teoretiska resonemang.
