Construction of wetlands in the agricultural landscape may reduce nitrogen and phosphorus transfer to streams, thereby reducing the eutrophication of lakes and seas. The agriculturalstream Lillån, a tributary to stream Sagån, ends up in Lake Mälaren and is transporting large amounts of these plant nutrients. The aim of this study was to estimate how hypothetical wetlands of different size and location may reduce nitrogen and phosphorus load from stream Lillån. Estimated nutrient retention in several small wetlands was compared to retention in a single large wetland based on existing data from the agricultural stream and from a nearby smaller stream. Retention in the stream was suggested to decrease along with the nutrient concentration in the water.

This study investigated the possibility of implementing three standards, Transistion Minimized Differential Signaling (TMDS) and two versions of Stub Series Terminated Logic (SSTL), for inter-chip communication in a specific manufacturing process. The two SSTL standards were implemented in one transceiver system while TMDS was implemented in a separate system. The evaluation was done with Spice simulations on schematic level with some parasitic capacitance and resistance. The idea was to investigate the possibility of implementing these standards and get an idea of eventual shortcomings. In order to create models as a basis for evaluation, simulation environments with models for circuit board and packages were created and transmitters and receivers were designed.

This master's theses was carried out on assignment from Stockholm Vatten AB as a part of a project developing new waste water treatment techniques. The goal of the theisis has been to evaluate an anaerobic membrane bioreactor for treatment of waste water from Hammarby Sjöstad. The bioreactor has not been heated and the main interest has been to study the gas production, power consumption and the reduction of organic matter and nutrients.The system has been completed with a reverse osmosis unit and a total of four batch runs have been made with good results. The use of reverse osmosis allows nutrient in the waste water to be reintroduced into circulation as the reverse osmosis concentrate can be used as crop nutrient.The membrane unit is of VSEP ("Vibratory Shear Enhanced Processing") type and an extensive membrane test has been conducted. This so called L-test helped determine the most suitable type of membrane for the system to allow a higher ±ux and thus lower power consumption.

Studie- och yrkesvägledningenhar de senaste åren varit utsatt för politisk debatt. Många experter, forskare och politiker har uttalat kritik kring verksamheten, framförallt för att granskningar visat att engagemanget kring området varit bristfälligt på skolorna. Utredningar har gjorts, projektarbeten har satts igång och rekommendationer har getts ut, allt för att öka måluppfyllelsen enligt områdets styrdokument. Syftet med studien är att granska problematiken från skolans eget perspektiv, genom att dokumentera röster från skolans insida. Elever, lärare och studie- och yrkesvägledare har genom enkäter fått uttala sig om sina personliga erfarenheter, uppfattningar och preferenser angående verksamhetsområdet.

The purpose of this study was to explore how interpersonal relationship can be affected by groing up in a New Religoius Movement such as Jehovah?s Withnesses and how it has affected them both in their youth and today. The aim was also to explore if there were people in the respondents' environment that was significant to them during their childhood and which support our respondents have received if they were in need of it.We have not found any previous research on children's social relationships within the Jehovah's Witnesses. We therefore believe that this study is of high relevance to both society and also for all the professionals who come into contact with these children. To discover a child in need, knowledge about how their social environment looks like is crucial.

This thesis has been done on a haulage contractor company named GP-Last (AB Gustav Perssons Åkeri) and the purpose with the paper was to analyse their traffic from Malmö to Stockholm and leave suggestions on efforts that GP-Last can use to increase their level of transportation quality. This has been done with two main questions, which problem do they have today and which efforts they need to do to solve their problems? Through a case study with interviews as method to collect data it showed that GP-Last had four main problems.        Not enough information about their freights. The transport planning unit in Malmö doesn?t have the exact delivery address when GP-Last begins to bring in the gods.        There are no clear routes.

The overall aim is to examine how the European Union Water Framework Directive has affected the local water management in the catchment Märstaån situated in the eastern part of the lake Mälaren river basin, Sweden. The first part of the study gives an historical overview of the area with focus on how the old agricultural landscape was handling the nutrient load from farming activities by means of different kinds of wetlands. By using the concept of the procedural landscape, introduced by Torsten Hägerstrand , together with historical maps with dates starting from the 17th century, the pre-modern landscape is analyzed.  The second part is an investigation, based on qualitative data, on how the different actors in the catchment area work together to secure the water quality for the Märstaån river. The analysis shows that the Märstaån catchment river systems are mostly unchanged in the rural areas.  The exception is the mainstream section of the Märstaån river running partly underground today and the Halmsjöbäcken river that is heavily affected by the Arlanda airport situated within the catchment area.

The purpose of this text is to show how social class is (re)produced and created in the short stories?Draksådd? byMaria Sandel and Ivar Lo Johanssons ?Nya tänder? from Statarna I and to point out ways that the short storiesmay be useful from an Educational Perspective. Maria Sandel was the first (recognized) female author to writein the genre of Working-Class Literature in Sweden and Ivar Lo-Johansson is a recognized authorship who ismost famous for his novels portraying Statarna. The analysis focuses on how the teeth motif is portrayed in theshort stories. My analysis proves how the teeth motif is important in portraying the construction of class.

Syftet med denna uppsats är att undersöka skolbarns tankar kring framtid, utbildning och yrken. Följande frågeställningar har formulerats: vilken beredskap har barn att diskutera frågor om utbildning, framtid och yrken? Vad är det som gör att barn tänker som de gör kring utbildning, framtid och yrken? Jag har använt mig av kvalitativ metod och genomfört sex intervjuer med elever på en F-6 skola och tre intervjuer med lärare. Tidigare forskning visar att det inom detta område finns sparsamt med undersökningar och att det även är svårt att hitta karriärteorier som specifikt handlar om hur barn resonerar och utvecklas. För att analysera det empiriska materialet har Supers teori om life span, life space, Gottfredsons teori om begränsningar och kompromisser och Social Cognitive Career Theory (SCCT) använts.

 Why is it that we still live in a society where an individual's social background plays such a big part in their chances of reaching a higher education? Despite the numerous educational policy reforms, especially in Sweden, it still seems that an individual's career choices are pretty much related to what kind of social class they grew up in. Sociologist Pierre Bourdieu claimed that social class is reproduced in the school system, and that students from the lower classes are much less likely to reach a further education than students from the middle or upper classes due to injustice in the school system. One thing that plays a big part in this "Catch-22" situation is the concept that Bourdieu calls habitus. Habitus could be explained as an individual's taste, knowledge, ability to master the spoken language, etc. Your habitus is manifested in the choices you make, the music you listen to, how you dress and the way you speak, and it determines your relation to the education system and life in general. As part of my essay, I wanted to interview students from lower or working class at my school, Konstfack, to see if they have had any negative or positive experiences from their encounter with a higher education. And if so, could they be linked directly to their social background? As a reaction to my own and my interviewees? experiences and frustration, I use the concept of habitus in my practical work.

The purpose of our paper was to understand the motivators that kept the social workers within the profession. Social workers' have a profession that, to the greatest extent, means high working load and difficult problematic issues. On the basis of this starting point we asked us why so many social workers still choose to remain within the profession for several years. The purpose of our paper is to understand what motivates the social workers to stay within their profession. To understand which are the motivators, we decided to use the theory salutogeent perspective with Aaron Antonvsky's sense of coherence.

Syftet med studien var att utvärdera vad tidigare klienter på Lenagården HVB, ett behandlingshem för vuxna med psykiska problem, upplevde som värdefullt, respektive vad de upplevde som negativt eller saknade i sin behandling. Utvärderingsfrågorna utgick från Lenagårdens programteori samt aspekter som tidigare forskning kring institutionsbehandling pekat ut som viktiga för framgångsrik behandling. Data samlades in via kvalitativa intervjuer med fyra tidigare klienter. Systemteorin har använts som utgångspunkt för resultaatanalysen.Utvärderingen visar bland annat att gott bemötande i termer av vänlighet och respekt samt personalens kompetens ansågs vara värdefulla faktorer i behandlingen. Själva terapin och behandlingsmetoden ansågs av samtliga intervjupersoner vara givande.

The web sites of Swedish public libraries display a high level of heterogeneity when it comes to design and graphical user interface. The thesis is based on the opinion that the visuals of a public library web site have implications for the user as well as for the library. The design of the graphical user interface influences the attention of the user and his/her ability to absorb information. Furthermore, there is a connection between the visuals and the users opinion about the credibility of the content of the web site, as well as of the organisation itself. The research question is: Which factors may have an impact on the design of the graphical user interfaces of a public library web site? The purpose is to create an understanding for these factors and emphasize them.

Den här rapporten handlar om Individuella utvecklingsplaner (IUP). Från 1/1-06 gäller en förordning om att alla barn i grundskolan, särskolan, sameskolan och specialskolan ska ha IUP. Syftet med rapporten är att undersöka vilken information lärare och elever fått om IUP, men också ta reda på deras inställning till och uppfattning om IUP.För att få reda på detta har jag intervjuat fem lärare och fem elever. Lärarna har mellan 3-20 års erfarenhet av skolarbete. Eleverna går i skolår 1-6.

With the increasing costs in concentrate the importance in producing ensilage with a high quality is becoming more and more important. To succeed with this goal it is of importance not only to harvest in the right period, but also to be able to store the ensilage without a decrease in quality and nutrional values. To maintain a good ensilage the covering of the ensilage must be carefully made. An unsuccessful covering causes mould to grow in the ensilage, which both increases the work load and also increases the amount of feed which is wasted. A bigger amount of spoiled feed also increases the risk of feeding spoiled feed to the cattle.
