Avfallsdirektivets påverkan på efterbehandling av förorenad mark
The purpose of this report is to increase the awareness about the problem that occur when the waste hierarchy is applied to management of contaminated land. The work with remediation of contaminated land in Sweden is part of the efforts towards reaching the national environmental objectives. Therefore a subsidiary aim is to analyze how this influences the prospects of reaching the objectives. The work consists of two parts; a case study and a comparative literature study that focus on England, the Netherlands and Sweden. The case study is intended to provide a practical perspective through a comparison of the climate impact from two methods.

Sahlgrenska Academy at University of GothenburgDepartment of Internal medicine and Clinical nutritionAbstractTitel: Can omega-3 prevent the emergence of allergy?? A systematic reviewAuthor: Karin Andersson and Cecilia BjörertzSupervisor: Henriette PhilipsonExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 hpType of paper: Examination paper, 15 hpDate: 2012-05-23Background Today allergy is a major public health issue and one of our most common chronic diseases. It would be most profitable if there was a way to prevent the emergence of allergies, both regarding the community and the individual. The antiinflammatory property of omega-3 influences the immune system and is thought to have a preventive effect on allergic symptoms. To investigate whether the mothers intake of omega-3 during pregnancy and lactation affects the child?s future development of allergy is therefore of high interest.Objective To examine if omega-3 supplement given to mothers during pregnancy, or pregnancy and lactation, is shown to be beneficial in children with heredity to develop allergy.Search strategy Articles were collected from the data bases PubMed, Cochrane and Scopus.
The diffusion of minimum tillage in agricultural China : a study of the factors influencing the farmers? choice of tillage system
The Chinese government´s aim to be self-sufficient in food production in combination with the increased food consumption in China has put high pressure on the productivity within the Chinese agricultural sector (He j et al, 2010). In order to increase the productivity, modernization and adoption of new farming techniques are essential. The opportunity to adopt and import foreign technology has lately been possible in China, as more authority and decision rights have been given to the individual farmers and the country has opened up for foreign trade (Zheng, 2012 & Fan, 1991).
A more open Chinese market enables new opportunities for foreign agricultural companies to expand their businesses by introducing their products to Chinese farmers. But to succeed with this strategy the Chinese farmers must be willing to adopt these, for them new innovations.
Minimum tillage is a tillage practice used worldwide that is suitable in northern China where drought and erosion are the main problems in the crop production (pers.com., Arvidsson, 2012).
Potential users? opinion of new innovations such as minimum tillage is closely related to adoption (Rogers, 2003).

Title: From inspectors to guides: how citizen journalism and participatory cultureaffect the professional identity of Swedish journalists (Swedish title: Från granskaretill guide: om medborgarjournalistikens och deltagarkulturens påverkan på svenskajournalisters professionella identitet).Number of pages: 44 (48 including enclosures).Authors: Towe Bengtsson and Matilda Källén.Tutor: Amelie Hössjer.Course: Media and Communication Studies C.Period: Fall 2011.University: Division of Media and Communication, Department of Informatics andMedia, Uppsala University.Purpose/Aim: The goal of this paper was to answer how citizen journalism andparticipatory journalism as well as an increasing range of information today haveaffected the professional identity and professional lives of journalists. In addition tothis, study how journalists today respond to these changes.Material/Method: The study is based on Deuze?s theories about journalistic ideals,Jenkins? theories about convergence culture, and on theories about professionalizationand de-professionalization based on Nygren, Wiik and Torstendahl?s theories. Thestudy is based on eight interviews with professional journalists, four employedjournalists and four freelance journalists. The results are analysed based on a broadtheoretical framework.Main results: The results of this survey show that the role of the professionaljournalist is extremely complex, with a strong ideological basis that fundamentallyinfluences the journalist's view of the profession and of him- or herself.
Hydraulisk och termisk grundvattenmodellering av ett geoenergilager i Stockholmsåsen
Geothermal energy can be extracted from an aquifer, where the groundwater is used as heatexchange medium while heat and cold are stored in the surrounding material in the aquiferand to some extent in the groundwater. Application of aquifer storage for the use ofgeothermal energy is mainly used in large scale facilities and is limited to sites with suitableaquifers in the form of ridges, sandstone and limestone aquifers.Löwenströmska hospital in the municipality of Upplands Väsby, north of Stockholm, islocated nearby the northern part of the Stockholm esker. This means that it can be profitableand environmentally beneficial for the hospital to examine the possibilities of aquifer storagein the esker material next to its property.The purpose of this master thesis has been to investigate if geothermal energy storage with aseasonal storage of heat and cold can be applied within Löwenströmska hospital?s propertyarea using groundwater modeling. A hydraulic groundwater model was constructed inMODFLOW based on a simplified conceptual model of the groundwater system.
Smak och konsistens hos ost : en litteraturstudie kring årstiderna och fodrets inverkan
To enjoy the richness of the grazing cows and high yield during the summers, even during the winter, cheese has been the way to store milk for thousands of years. Nowadays yield is high all year around and the cheese production is possible during all seasons. The aim of this paper
is to investi-gate how and why the seasons influence taste and texture of pressed and ripened cheese. Milk is composed of proteins, fat, lactose and water but contains also a lot of vitamins. The quality of milk is very important for the final constitution of cheese.
Frihet till hat? : Hatbrott, rasistiska organisationer och inskränkningar av yttrandefriheten
The present paper is part of a project carried on by the Swedish Section of the International Commission of Jurists. Sweden has ratified several major international human rights instruments. Most of the rights are covered by national law, and only in exception is there a discrepancy between national and international law. Such a discrepancy is found in the UN Convention on the Elimination of all forms of Racial Discrimination, in which the State parties agree on penalizing and prohibiting the founding of and participation in racist organizations. Sweden is not complying with this statute, despite the fact that the government has ratified the convention.
Överpronation kopplad till ryttarens sits
According to ?Fotförbundet" (2012), Overpronation occurs frequently (80 %) in the Western World and furthermore overpronation of calcaneus influences the position of the pelvic and thorax (Fotförbundet, 2012; Behnke, 2008).
The aim of this study is to investigate whether or not it is possible to connect overpronation of calcaneus to the problem in the rider?s seat as observed by the instructors of Strömsholm. The study will also investigate if the riders seat problems as noticed by the riding instructors are comparable with the problems found by the analyst during testing. One purpose with the study is to raise the instructors and riders awareness that anatomical deviations in the rider might influence the rider?s position in the saddle.
The questions of the study are:
- Is it possible to see seat problems in riders with overpronation of calcaneus?
- If it is possible to see more seat problems in riders with overpronation of calcaneus, do the instructors in the study considers the seat problems be similar with each other?
- If there are seat problems in the study, is it the same according to the instructors and the analyst in human biomechanics?
The hypothesis of the study is that overpronation of calcaneus has an effect of the rider?s position in the saddle.
The study is conducted as a blind study where the test subjects have been filmed (from knees down) as they walked barefooted and later while riding.

Case study 2: Farm A - a study of the precedence passage and the cow traffic
Case study 3: Farm B ? an overview of the farm and their way of working
Case study 4: Key factors ? how can we judge how well a VMS farm is working?
Case study 1: Lactation chart comparison from traditional cow traffic and Feed First? cow traffic
In this survey data is analysed from before and after rebuilding to Feed First? cow traffic. Lactation
graphs are compared between traditional cow traffic and Feed First? cow traffic.
Förbättrat råvaruutnyttjande vid kvalitets-sortering av timmer : utvärdering av analysprogrammet Stockholmen för automatiserad timmersortering i dimensions- och kvalitetsklasser hos BARO WOOD AB
The aim of this thesis was to analyse BARO WOOD AB:s timber measuring and quality sorting and to evaluate the analyse program Stockholmen. The purpose was to get a better understanding for the quality sorting made at BARO WOOD AB today, analyse differences in center board quality from logs with a good quality and logs with a bad quality, suggest new sorting criterias developed from analyses made with Stockholmen and to evaluate the program Stockholmen. All analyses are based on data gathered in a test sawing made at BARO WOOD AB in June and July 2002. The test sawing was made on four different diameter classes and every diameter class consisted out of A or M-grade logs, with a better quality, and B-grade logs with a lesser quality. The logs where sorted out with BARO WOOD AB:s existing quality criterias.
Social behaviour and time budget of breeding bulls
The aim of this study was to investigate the social behaviour and time budget of breedingbulls kept at VikingGenetics, Falkenberg in Sweden when the staff was off duty. It was ofinterest to see if there was any difference between bulls housed in group pens and bullshoused in individual pens. It was also of interest to investigate if there was any differencein the behaviour between the dairy breeds Swedish Red (SR) and Swedish Holstein (SH).Sixteen bulls were used in this study. Eight bulls kept in individual pens and eight bullskept in group pens were used. The individually housed bulls had a social gate with widerbars where the bulls could but their head and neck through to have social contact with thebulls in its neighbouring pens.
Effects of shade on milk production in Swedish dairy cows on pasture
Heat stress negatively influences the performance of dairy cattle such as lactation and reproduction. Heat stress can cause production losses as well as welfare problems. Years of research have shown that heat stress is a huge problem for dairy cattle in both the tropics and temperate zones but no such research have so far been done in northern European countries. It seems like shade is an important tool when improving pasture conditions and therefore
deserves more attention. The aim with this study was to investigate whether there is a need of providing shade for grazing dairy cows during the summer in Sweden.
Two groups of lactating Swedish Red dairy cows (n=15 per group) were kept on pasture.
Kundorderstyrd tillverkning ? Påverkande faktorer, förutsättningar och problem : En övergripande studie om hur små och medelstora företag flyttar kundorderpunkten och går mot mer kundanpassning.
This study presents a holistic view of which factors small and medium-sized enterprises (SMEs) have to consider, in moving their customer order decoupling point (CODP) further from the customer, thereby becoming more customized. The study also investigate whether SMEs and larger enterprises differ in the strategic questions relating to what influences an enterprise to become more customized, which prerequisites are required and which problems enterprises should anticipate and prepare for. These questions are important, given that strategic change is challenging, and can take considerable time to accomplish; it therefore needs to be based on the right decisions. This study is motivated by the fact that the markets SMEs are selling to tend to become more and more complex and harder to anticipate. Increased globalisation and use of IT and ICT have lead to greater uncertainty in customer demand.
Den internationella kontextens påverkan över en nations demokratiseringsprocess under transitionen från ett auktoritärt styre till ett demokratiskt - En analytisk kategorisering
AbstractBachelor thesis in political science by Alexander Hassan, autumn 2008, ?Effects of external factors on a nations democratisation process during the transition from authoritarian to electoral democratic rule ? A categorical analysis?Supervisor: Tomas SedeliusIn recent years globalization has become a hot topic in understanding the world we live in today. Globalization has indeed had a great impact on international relations and with it a great influence on the domestic conditions that determine a nation?s possibilities. It is therefore rational to hold true that this also would apply to a nation?s democratic process.
Påskfirandet i två lokala kristna församlingar Immauelskyrkan SMK,Stockholm Ndjilikyrkan,CEC,Quartier5 Kinshasa
The main aim of my research essay is to examine two congregations, one in Sweden and one in Democratic Republic of Congo, how theology and the life in the church shape the cultural context. The analysis uses semi-structured interviews of two pastors responsible for organizing the Easter celebration in their churches. The interviews serve the purpose to reveal how they apply theology in their context, how they interpret the Easter celebration liturgically in relation to the early church and how they perceive the cultural development in the congregations Easter celebration 2010-11. To give complementary insights to the interviews I use computer-aided interviews with members of the congregations. The methodological approach is based on a study of contextual theological theories, Easter traditions in the early church, Easter theologies and then applying these theories in the interviews.
