Nowadays naval units are participating in international missions, where new and in many cases tougher conditions will affect their propulsion. This essay deals with some of the now developed nanostructure coatings and gives a presentation of how the coatings could function on some exposed parts of the naval powertrain. The essay investigates the possibility that the coatings can be used as a protective layer that will reduce or prevent wear on selected parts of the naval powertrains. As a basis for the essay, nanotechnology is described, as well as different reasons that wear occurs and application techniques for coatings The conclusion is that nanostructured coatings can be applied and provide a much better result on hardness and wear resistance as of naval powertrains compared to micro-structural coatings, both for manufacturing and renovation. The essay presents a few examples of the military utility of the nanostructure coatings as well as suggestions for further research..

This paper addresses the need to review the modern presentation of textile archaeology in museums. It is time to look at textiles in archaeology with new eyes. The reality behind archaeological textilestudy is holistic, embracing many different aspects of society. The presentation of textiles has in my opinion become old-fashioned. I will show in my paper that Jonathan Adams? `seven constraints´ model, developed for research on ancient ships, can also be applied to textile research.

Sweden is usually seen as a role model when it comes to integration and diversity, but at the top of the pyramid there is little ethnical diversity to be found. This paper investigates how existing economical and sociological theory explain the lack of swedes with foreign background in leading positions in large Swedish companies. Our findings show that none of the theories applied in this paper can explain the phenomenon in isolation. Thus it is not only taken for granted norms, contacts in one's network or cost minimizing under asymmetric information that lie behind the phenomenon, but an interaction of these aspects. Conflicting demands lead the recruiters to separate talk from decision, the search frame is narrow and no or small efforts are made to increase the diversity.

In this thesis we calculate the Hawking mass numerically for surfaces in Kerr spacetime. The Hawking mass is a useful tool for proving the Penrose inequality and the result does not contradict the inequality. It also does not contradict the assumption that the Hawking mass should be monotonic for surfaces in Kerr spacetime. The Hawking mass is quasi-local and defined by the spin coefficents of Newman and Penrose, so first we give a discussion about quasi-local quantities and then a short description of the Newman-Penrose formalism..

Our essay is about the grammar structure that the participants in A- and B- level of a school in the middle of Sweden, in the subject, Swedish as a second language, process. We have collected written productions from an A-level group and a B-level group and made a comparison between them morphologically and syntactically according to the processability theory by Pienemann.Processability theory was applied to Swedish by Pienemann & Håkansson (1999), with five steps in syntax and four steps in morphology. It turned out that the B-level group had much higher processing level of grammar than the A level group and one of the reasons for this can be that grammar is explicitly taught during the first year of studying Swedish as a second language in the school we have chosen to study..

Issue of study: The development of technology and society is closely linked. Mutual dependency and complex interrelationships make straightforward analysis of issues regarding the future of technology and society hard to perform. Therefore, the study addresses the question of how organizations should describe and analyze the interactions of technology and society in order to gain a better understanding of what the future may bring. Purpose: ? To develop a method for analysis of the future course of issues regarding technology and society in interaction.? To apply and test the developed method through a case study, where it is used to analyze the future of the Russian fuel market.

The essay, which is solely theoretical to its form, presents a critical view upon the unproblematized usage of the concept of ethnicity in the Swedish mass media discourse. Theories of critical discourse analysis and post colonial nature is applied to and used to analyze what ethnicity really means. The essay also provides an insight in the functions and power of mass media in Sweden today to understand why ethnicity is so widely used, and what consequences it may bring upon the systematically excluded "other" and the society as a whole..

I denna uppsats undersöks det svenska språket i öppen kommunikation på Internet för att se om det förekommer ett gemensamt språkbruk för både synkron och asynkron kommunikation, närmare bestämt för chatt respektive diskussionsforum.Bredvid uppsatsens huvudsakliga syfte följer också två frågor:- Skiljer sig det studerade språkbruket åt mellan olika åldersgrupper?- Vilken syn har chatt- och forumdeltagare på sitt eget skrivande i de olika sammanhangen?.

This report describes the process of developing a user-friendly and responsive archive website. The website is a Hi-fi prototype and was created for the company JG Communications, to serve as an archive for their customers? style guidelines. To create this website I have used HTML5 and CSS3 to make it responsive for various computer screens. I have also used PHP and some JavaScript to make some of the functions and Adobe Photoshop and Illustrator to make design elements for the prototype.

Föreliggande studie är ett försök att få fram relevant information kring realisering av kvantitet i två svenska dialekter. Föremål för undersökningen är eliciterade enstaviga minimala ord från två talare av gotländska samt två talare av skånska. Materialet, som spelats in av dialektprojektet SweDia 2000, ger möjlighet att i flera dialekter studera kvantitetsfenomenet med hjälp av samordnade, jämförbara ordlistor..

Med utgångspunkt för tre forskningsområden: semiotik, pragmatik och kognition, har det gjorts ett försök i att belysa om språket och bilden har skilda roller i den moderna TV-reklamen. Ett noga urval av dagens TV-reklamfilmer användes som underlag för den empiriska undersökningen undersökningen. För att besvara syftet och frågeställningarna testades reklamfilmerna ur två kognitiva aspekter: kognition och affekt. Resultatet som framkom i undersökningen ligger som grund för en diskussion huruvida det går att tala om skilda roller för språket och bilden..

Abstract This essay is about girls that have chosen a gender atypical education on a gymnasia level. Since we are living in a society that is still today gender segregated in both working life as well as educational area, we find it interesting that it still exist an paradox which leads us to the question ?why? those girls and boys, woman and man choose so differently. We are not aiming towards study how many girls that have chosen a gender atypical education but rather how these girls that are on the construction program in one of Stockholm?s gymnasium have deliberated and what it is that has influenced them.
