Foderbetor och kogödsel som substrat för biogasproduktion; anaerob mesofil samrötning i labbskala
One of Sweden?s sixteen national environmental objectives strives to decrease the impact on the climate. By 2020, green house gas emissions should be 40 % less compared to the levels of 1990 and a minimum of 50 % of the energy consumption should come from renewable energy sources. Because of this there is a great need of increasing the production of renewable energy. This is where biogas comes in as a competitive alternative.
Undersökning av processparametrar för optimering av sol-gelprocessen för produktion av kärnbränsle
A clean and affordable energy source for cooking is deficient in developing countries. People rely on fuels that contribute to environmental, social and health problems.Biogas is an alternative energy source and an increased investment in small-scale biogas production can in several developing countries be found. Several projects have started to use the technology in developing countries because of the benefits with biogas. Some cases in the establishment of biogas plants have succeeded and some have not. The study is a literature review supplemented by two field studies.
Maskulinitet i läromedel. En kritisk diskursanalys av en lärobok i religionsämnet
This study indicates that research about men and masculinity does not appear to have advanced as far as research about women and femininity. Similarly to attitudes concerning women and femininity, clear norms and attitudes regarding men and masculinity pervade society. Hence, there is a clear need for further research within this field to be carried out. This study, with the support of previous research, looks at gender norms which exist in educational material and the impact it might have on students. Against this backdrop, the author has focused the analysis on one textbook as educational material at upper secondary level with particular emphasis on masculinity and its associated norms.
Offentlig skyddad anställning: vad händer?
The Forthcoming Essay concerns the publicly protected employment (Offentligt skyddad anställning), it's content and what actually happens to its participants after they have retrieved it. We have also, during our research, discovered a great lack of background research concerning this subject. Beside statistics and publicly protected employment rulework there only exist a small amount of research. This is mainly focused on people with physical function disorders and socialmedicial function.Of that we believe there is an urgent need to undertake more research in this unexplored sector of the labour market. Our purpose with this essay was to examine what happened to publicly protected employment -participants after they had undergone the process.- In what ways has the participation in publicly protected employment altered their possibilities on the labour market?- What happens to the participants when they after the participation in publicly protected employment as judged qualified not for the labour market?In this essay we have chosen a qualitative method as an approach, mainly because we consider our material as being qualitative in its character.

Mobiltelefon utformad med EcoDesign
The environmental demands are increasing when it comes to product development. EcoDesign isabout minimizing the environmental impact of a product, considering the entire life cycle of it,without compromising other qualities like function or cost. In this master of science thesis amobile phone has been analysed with Ten Golden Rules in EcoDesign regarding production, useand End of Life. Also a functional and an environmental profile were made. The goal was tomake a new concept phone, based on the previous analysis, which communicates userfriendlinessand sustainable development.
Muddring i Ireån : indirekta effekter på bottenfaunan nedströms
This research aims to investigate the effects that dredging may have on benthic fauna. The dredging took place in the stream Ireån on northern Gotland during the early summer 2010. My area of research was taking place in a scenic area downstream in Ireån close to the Baltic Sea. I chose this area due to the dredging that started just upstream of this area and continued further upstream. Thus it is not the direct impact of the dredging that is the focus for this paper but the side-effect the dredging may have on the area downstream.

Konst, mångfald och representation : Hur begreppet mångfald manifesteras i och kring konsten vid Södertörns högskola
This research shows and analyses how pupils in ninth grade in the nine-year compulsory school look at being multilingual, at the Swedish language and at Swedish as a second language. I also want to know if language and culture knowledge are taken care of in school as it says in official documents for the Swedish school and as it also is desired in an intercultural education. For my research I do eight interviews in a suburb school south of Stockholm.My work includes a limited account for the current research about being multilingual, Swedish as a second language and about the close relationship between language and culture. The applied theory is a social constructivist theory which in short can be explained like that we construct social structures that have consequences on the individual as well as on the society.I show in my research how the view of the world around the pupils influences their view on their languages, their school and their neighbourhood. I also draw conclusions from my interviews that language knowledge is little appreciated in school and that Swedish as a second language has a low status..
