This thesis evaluates the environmental performance of six different fish farming systems. The thesis is part of the network group ?Hållbar fiskförsörjning I Stockholms län? (HFFS) which tries to increase the domestic and regional production of fish in Stockholm and move to a more sustainable supply in the Stockholm county. Two of the chosen systems; pangasius from Vietnam and salmon from Norway are delivering a substantial part of the fish consumed in Stockholm today, although they are very different when it comes to system characteristics. One system, arctic char with conventional feed, is produced in a fairly small scale in the north of Sweden, while the three remaining systems are viewed upon as possible options to supply Stockholm with fish in the future.

FDI har sedan början på 80-talet växt sig allt större och blivit en av de viktigaste tillgångarna till finansiellt och fysiskt kapital i världen. FDI har enligt många studier en viktig funktion för ett lands ekonomiska utveckling, detta gäller främst för outvecklade länder men också utvecklade länder. Studiens mål var att hitta viktiga faktorer som påverkade FDI inflöde till Sub-Sahara regionen. Den empiriska analysen gjordes med hjälp av en OLS regressionsmodell och hade 42 observationer sammanlagt. Huvudvariabeln var FDI/BNP.

The environmental debate is more intensive than ever before and the demands on companies increase. There are a number of methods to make it easier for the companies to fulfil the demands. Life Cycle Assessment (LCA) end ecodesign are some of the methods that can be used. Syntronic AB has the possibility to reduce the products´ environmental impact in the design phase. Therefore it is important for the company to make it possible to visualize the negative environmental impacts a product can cause in an easy way. It is also important to visualize for there clients if any improvement is possible. The purpose of this thesis is to develop a simplified model.

This study investigates whether the permanent measurement bias (PMB) has changed over time for Swedish companies listed on the Stockholm Stock exchange at least one year during 1996-2000 or 2005-2010. By using the Residual Income Valuation-model the markets' implicit value on PMB is generated through reversed engineering, as values for all variables except PMB are entered such as the market perceived them at the specific valuation date each year. This implicit value is classified into industries and then sorted by their median. Statistical tests are performed to see if there is a difference between the industry median and the accounting-based values on PMB. The difference from period one to period two is also statistically tested for.The study finds that the implicit values on PMB have changed somewhat between the periods; however the fluctuations are not statistically significant.

This article presents a retrospective case study combined with a review of the current literature concerning canine gestational diabetes. A total of 14 cases have been collected from six different clinics in Sweden. There are few previously published reports on canine gestational diabetes. Gestational diabetes is a disease that rarely occurs in pregnant bitches. The condition is due to the rise of progesterone that occurs during the estrus cycle.

This thesis is based on a case study for the real estate manager Mimer in Västerås. Mimer provides a great deal of this city?s rental apartments. Many of their buildings have ventilation systems with a type of heat-recovery called ?heatpipe?.

This project operate an environmental assessment of total waste was conducted by using a life cycle assessment (LCA), that examines the environmental benefits of recycling production waste from Atlas Copco at Stena recycling. Atlas Copco is a company engaged in the development and production of rig-mounted hydraulic breakers and handheld air breakers and handheld motorized rotisserie. Stena recycling is a recycling company engaged in recycling, processing and refining of metals, paper, electronics waste and hazardous waste.The purpose of this study is to focus on Stena customer Atlas Copco and evaluate environmental benefits between to recycle and not to do it. The result shows that the total energy gain, resulting from the recycling of waste fractions, lands at 6 990 089 MJ, corresponding to drive 3 times around the Equator with a truck (40 t). The result shows that recycling 3040 kg paper provides an energy gain of (38 600 MJ) compared with burning paper (19 500 MJ) is 19 100 MJ, which corresponds to heat a house for 11 weeks.

Industries with energy costs as a large proportion of their total costs are greatly affected by the instruments deployed to cope with the Swedish climate and energy policy goals. With energy costs representing more than 30 % of the total costs, tomato cultivators are one of the affected industries. In order to remain competitive with other countries, a more resource- and cost-efficient cultivation of tomatoes in greenhouses is desirable in Sweden. Based on the concept of industrial symbiosis, this study investigates the prerequisites for a resource-efficient production of locally grown tomatoes in Sweden through the utilization of low grade industrial waste heat. The study is based on the foundry industry as the supplier of waste heat.To investigate the environmental, technical and economic potential of the exchange of waste heat, a comparative life cycle assessment, an inventory of the supply of industrial waste heat in Sweden, a compilation of potential technologies for the recovery of low grade industrial waste heat for heating greenhouses and a comparative life-cycle cost calculation were carried out.

Stormwater in urban areas has been treated as a problem for a long time. The large proportion of impermeable surfaces inhibits the water from infiltrating in the ground to the same extent that it does in nature. This causes intensive surface flow during rain, which in turn causes inconveniences such as decreased accessability, floods and increased risk of desease spreading. Drainage through pipes is the traditional and usually functional metod for storm water disposal. That is as long as water flows are moderate. But precipitation varies naturally in amount and intensity and additional impermeable surfaces make some pipes insufficient for heavy or lasting precipitation.

Nuvarande metoder för att diagnostisera svampinfektioner i nagel är långsamma och troligen ganska okänsliga. Diagnostik görs vanligen genom direktmikroskopi och odling på svampsubstrat. I ett försök att minska analystiden och att öka känsligheten användes i denna studie realtids-PCR (Polymerase Chain Reaction) för att påvisa dermatofyter. Optimering och validering gjordes av en PCR som var generell för dermatofyter och en PCR som var specifik för Trichophyton rubrum. Optimeringen innefattade annealingtemperatur, Mg2+-koncentration och primerkoncentration.

There is no general aging process therefore should health efforts directed at elderly population based on each individual as a unique person with specific needs. When aging becomes a fact not generally decrease the lust and the desire to be active but it is perhaps more about the body's ability to keep up on what the head wants. Therefore the range of activities towards the elderly population requires some adjustment that can partly be achieved by taking some of the older people?s experiences. The purpose of this study was that by the older people?s experiences of organized activities in a social context to illustrate how they perceive their participation.

The dishwasher is a wide spread product that occurs in many households. It saves the user time,water and energy. When using a dishwasher instead of doing dishes by hand a lot of energy issaved.The importance of lowering the energy consumption does not only come from the consumerwinnings but also from an environmental point of view. Scientists are certain that the globalwarming comes from the emission of green house gasses that is created by human consumptionof oil, gas and coal.Dishwashers today are a lot more energy efficient than older dishwashers, but there are stillmargins to lower the energy consumption. The aim with this project is to investigate thedishwasher and it?s washing cycle, noting different phases and components that contribute towaste of energy.

Avsikten med detta arbete är att undersöka vilka känslor och tankar elever kan ha till djur, samt om de kan ändras när eleverna blir bekanta med djuren. Vi har valt att utföra en kvalitativ undersökning där vi kombinerar metoderna intervju och observation. Undersökningen genomfördes på tio elever i årskurs ett, där alla enskilt fick bekanta sig med en skalbagges alla livcykelstadier under ca 10 minuter. I början och slutet av varje intervju bad vi eleverna att berätta vad de kände och tänkte när de såg djuren, därefter grundade vi vår analys och tolkning av vårt material med hjälp av konstruktivismen. I vår undersökning såg vi att alla elever hade någon sorts känsla för och tanke om djuren, dock kunde det vara svårt att tyda känslorna eftersom vissa elever verbalt kunde uttrycka en känsla medan kroppsspråket visade en annan.

This thesis analyses the rise and fall of social movements. Social movementsfunctions in the civil society, by contentious collective action they form identities,mobilize their forces and use repertoires of contentions to make new or previouslyunaccepted claims. They function in a limited timeframe, sooner or later they getinstitutionalized, marginalised or succumb into violence. The landless movementin Brazil is one of the most profound social movements in the world; their majorgoal is a land reform. Since the leftwing president Lula da Silva won the Brazilianelection in 2002 the president has been unable to live up to the expectations fromthe landless movement about implementing a land reform.
