Biogas is a renewable energy source that is produced by anaerobic digestion of organic mate-rial. In Sweden, biogas predominately comes from sewage water sludge and landfills or from organic waste of households and industries. Small scale digestion plants at farms are espe-cially expected to contribute to increased biogas production in the future. Biogas can be ob-tained directly in it?s raw form and used as fuel in a combustion chamber.

To guarantee protection of our drinking water, water catchment protections are established. These are divided into three different zones and in the first zone it is most likely that an activity, such as agriculture, will contaminate the water resource. Hence the activities are strongly regulated or banned. The EU communion is working towards a sustained water quality through several directives; Nitrate Directive, Waterframwork directives and Sustainable use of pesticide directive. The main purpose is to regulate the diffuse pollution from agriculture.This thesis is about how Denmark, Germany and France are working towards a sustainable agriculture within water protection areas.

Syftet med föreliggande studie var att undersöka och jämföra motivationen hos amatör- och elitfotbollsspelare mot bakgrund av ålder, prestationsnivå och attribuering. Följande frågeställningar har besvarats: (1) Skiljer sig motivationen åt mellan elitidrottare och amatöridrottare? (2) Attribuerar elitidrottare och amatöridrottare olika? (3) Påverkar ålder motivationen? Försökspersoner (n=32) i ett amatörlag (n=16) och ett elitlag (n=16) fick fylla i en enkät, uppbyggd av Sport Motivation Scale och Attribution Theory. Ett oberoende t-test och ett korrelationstest utfördes. En signifikant skillnad upptäcktes mellan amatör och elit på kategorierna Inre Motivation och Amotivation.

Motivation är en betydelsefull kompontent för en individs utövande utav studier. Studien utgick ifrån motivationsteorin Self- determination theory. Syftet med studien var att redogöra för relationen mellan högskolestudenters demografiska faktorer och vilken typ av motivation som driver dem till att utöva studier, samt relationen mellan motivationstyperna. Med typ av motivation avses amotivation, inre samt yttre motivation. Studien bestod utav 102 studenter, varav 49 män och 53 kvinnor, från en högskola i mellersta Sverige som fick besvara enkäten The Academic Motivation Scale.

Bakgrund: Sedan 1988 har svenska aktiebolag haft en lagstadgad skyldighet att få sina räkenskaper granskade av en kvalificerad revisor, något som snart kommer att förändras. I en pågående utredning presenterades den 3 april 2008 ett förslag om att avskaffa revisionsplikten för 96 procent av de svenska aktiebolagen från och med 1 juli 2010. Bakgrunden till detta är att fördelar för små bolag inte anses uppväga nackdelar av revisionen.Syfte: Syftet med denna uppsats är att beskriva förändringen hos banker i kreditbedömningsprocessen vid ett avskaffande av revisionsplikten och hur dessa förändringar kommer påverka relationen mellan bank och bolag.Referensram och teori: För att analysera det empiriska materialet har intressentteorin, principal-agent teorin och teorin om asymmetrisk information använts varav samtliga är väletablerade och beprövade teorier. Teorin om tillit är en relativt ny teori som även denhar använts i syfte att förklara betydelsen av tillit i näringslivet. I referensramen ges information om revision och dess grundläggande principer samt en beskrivning av banker som kreditgivare och deras kreditgivningsprocess.Metod: För att uppnå syftet har en fallstudie utförts bestående av både en kvalitativ samt en kvantitativ insamlingsmetod.

Our planet is faced with enormous challenges as the extreme weather events related to the human-caused climate change continue to gain strength. The scale of the problem has made changing human behaviour the central focus of sustainable development, and both public and private sector are expected to gain relevant expertise and introduce this work in their agenda. Over its 40-year history, social marketing has become an established field providing tools for social change, but compared to health promotion, sustainability has not been a major focus of social marketing research so far. At the same time, sustainable lifestyles are embedded in complex systems where both individual factors and those of physical and social environment play a defining role in their adoption. Communities are a good example of such environments, and they became the key focus of Community-Based Social Marketing, which combines different insights from psychology to suggest a step-by-step framework for crafting behaviour change campaigns. However, it has not been applied to larger and diverse communities, like cities, and has not focused on sustaining new behaviour over time, which is crucial for creating sustainable lifestyles.

This report summarizes a Bachelor Degree Project in Integrated Product Development,carried out during the spring semester in 2007 by three students at the Product Design Engineering programme at the University of Skövde. The project was performed as an assignment for KinBag ab, a sister subsidiary to Kinnegrip ab in Lidköping, who develop,manufacture and market the golf bag KinBag, a bag with an integrated wheel carriage system. The purpose of the project was to redesign the golf bag to attract a target group consisting of golfers aged between 20 and 40.The layout of the project was as follows: The project began with a feasibility study where different problems were identified with the basis of a market research which eventually was summarized in a dynamic specification of requirements. The feasibility study was followed by a generation of ideas which contained everything from sketches to simple mock-ups with an intensive amount of thoughtful brainwork and information gathering in between. This ledto the development of a number of design concepts, both on an overall level and on different parts of the golf bag.

In the country of Jordan, egg production is very important economically, but several bacte-ria are involved in food borne diseases transmitted from eggs or other poultry products. The most important are Salmonella spp., Campylobacter jejuni and Escherichia coli. In Jordan two different housing systems are used for hens in large scale egg production; con-ventional cages and litter floor systems. Eggs from four different farms were analysed and compared to see if a difference could be found regarding the presence of pathogenic bacte-ria on the egg surfaces between these two systems. Total number of aerobic bacteria was analysed, the presence of Salmonella spp., C.

The purpose of this study was to investigate the association between physical activity and perceived stress, energy and musculoskeletal disorders among office-workers and warehouse-workers and also to see if there were any differences depending on work-place and gender. The method that was used to collect data was three different validated questionnaires that measured stress and energy (the Stress-Energy questionnaire), musculoskeletal disorders (intensity and localization of pain, a Pain Drawing questionnaire with a VAS-scale) and physical activity (IPAQ ? the short version). Eighty-eight workers participated in the study. Forty-seven of them were office-workers and forty-one were warehouse-workers.

In this thesis I investigate aesthetic preference for picture books among children aged 3?6 as well as criteria for preference among parents. Through my design project: illustration of a picture book, I aim to put my research on preference in the context of illustration and design. By using the design project as an applied method for research I have sought to answer how one as an illustrator can apply knowledge regarding preferences of the target groups when illustrating for picture books. I have primarily based my research within the field of cognitive developmental psychology, with primary focus on stage theory, and the field of literature.

Sydkraft Vattenkraft AB owns and operates the Traryd hydropower plant, located in the river Lagan in the southern part of Sweden. The gravity dam is classed according to RIDAS guidelines (Hydropower Industry Dam Safety Guidelines) as a class 1B dam. This means that the dam must discharge a class 1-flow which has a return period of 10 000 years. The inflow into the dam has been calculated in an earlier report to 495 m3/s, with a waterline at an elevation of 126, 3 meters above sea level. The gravity dam has a discharge system with two rectangular weirs, which results in a smaller discharge than the necessary 495 m3/s.

With a changing climate, we can expect higher temperatures and more precipitation in Sweden.As the temperature increases, new weed species are expected to migrate in from more southerlylatitudes, resulting in requests for new techniques for weed control. In addition, we might see agreater number of weed species and higher biomass production due to increased concentrationof CO2 in the atmosphere.Increased understanding of the biology of specific weed species will become more importantin future weed control. This will help to control the weeds more efficiently. Higher prices onpesticides and a public demand for reduced use of pesticides make growers more inclined to usemechanical weed control on a larger scale and to a greater extent prevent weed establishmentbefore sowing. A well-planned crop rotation is the most important preventive measure, whichmight also include delayed sowing, and dark harrowing and sowing.Research takes place on many levels within the weed area and several alternative methodsare being developed.

Today, nine out of ten municipalities are active on social media and it has become increasingly popular among municipalities that make use of placemarketing to promote their particular region. A problem that is raised in this study is that the population of the municipalities in northern Sweden often is in decline. The purpose of this study is to investigate how a democratic-controlled organization such as Luleå Municipality uses the social media Facebook in its placemarketing, to highlight a place of scale and to attract new residents and stakeholders to move to or visit the city. In order to answer the purpose I have with the help of a critical discourse analysis examined how Luleå Municipality using social media Facebook in their marketing of Luleå as a place. The results were then analyzed using theories of placemarketing, Norrland and the market-oriented municipality.
