The plants in the genus Elatine are characteristic for oligo and mesotrophic lakes. This study focuses on Elatine hexandra one of the four species in Sweden. It is stated as vulnerable by the National Environment Agency and a conservation plan with guidelines to preserve the plant in Sweden is under preparation. There have been a few previous studies investigating this plant in other countries but this is the first one for Sweden. The aim of this study was to investigate the distribution, growth and reproduction of E.

This literature study deals with the pig industry and how group size and available floor area affects the animal welfare and the production results. It shows that both the pigs? welfare and production result can be affected negatively if the environment seems stressful for the pigs, and if they are housed in a narrow area. If the pigs are being exposed to either physiological or psychological stress factors their immune system can be decreased and the growth can be impaired. Influence by the social status of the pigs is also reviewed.

The aim of this thesis is to examine the properties of the municipalities in Sweden that influence the choice of being a certified Fairtrade city. The independent variables which are used in the statistical analysis are municipal governance, local tax rate, whether there is an university and/or university college in the municipality, average income and higher education in the municipality. The variables are examined by logistic regression. Since there are no statistical data on ethical procurement, this exogenous variable isn?t included in the regression.

Purpose: To examine if the management of the public sector organization Sida actively work with how to motivate their employees. We also examine which factors of motivation dominate amongst the employees.Method: A case study with a qualitative approach was conducted, using semi structured interviews and a survey to gather data. By connecting motivation theories with collected data, we analysed the results to find similarities, differences and relations between them.Theory: The study is based on motivation theories and other contributing research.Conclusions: The study shows that management actively work with how to motivate their employees. But the employees are not aware of how management work with motivation. The majority of the motivation factors are highly valued, but the dominating factors are personal growth, stimulating work assignments and the ability to know the results of their work..

Transformation of inorganic mercury (Hg) to methyl mercury (MeHg) is a biotic process that is proposed to be conducted primarily by sulphate reducing bacteria (SRB). The formation of MeHg is of great interest because it is the mercury species that biomagnifies to the greatest extent in the aquatic food webs; about 90 % of all Hg in fish is MeHg. Our understanding of factors involved in the production of MeHg is very important for making a reliable risk assessment. The purposes of this study were to investigate the different factors that control the solubility of Hg and the production of MeHg in a contaminated lake sediment. The lake Ala-Lombolo, Kiruna municipality, is well-known to be contaminated by mercury from different sources. Sediment cores were sampled at three different locations (N, SW and SE) in the lake and divided in three different layers; 0-5, 5-10 and 10-15 cm.

Politiska och ekonomiska svängningar samt geografiska förutsättningar präglar stadens fysiska planering samt dess uttryck och form. För Lund och Köpenhamns räkning har planeringsprocessen under drygt femtio år tillbaka skett utifrån ett antal plandokument, upprättade för att kontrollera stadens utveckling. Studier av dessa dokument visar hur städerna fysiskt brett ut sig i landskapet samt argumenteringen kring denna tillväxt. Under 50- och 60-talen bredde städerna ut sig för att kunna erbjuda fler och bättre bostäder under devisen ?välfärd åt alla?.

The purpose with this study is to investigate funds that are environmentally friendly. Environment issues has become a large subject that affects all aspects in today?s society.  It is a global issue which has affected the awareness of environmentally friendly products and its benefits for the environment.How has this awareness affected the financial market?  In this study the authors have looked at six environmentally sound funds and six energy funds to answer the question if it´s better to have your money in traditional energy or in renewable energy.This study is made in an quantitative way, the data has been gathered from the internet database Morningstar. The energy funds have had its biggest assets in companies dealing with oil, and the environmentally sound funds have had its biggest assets in renewable energy. Bye looking at the different funds rate of return and relating that to risk managing theories of Sharpe and Treynor, the authors compared the two types of funds.During the period that was looked at during this study ( third quarter of 2007 until third quarter 2010) the energy funds outperformed the environmentally sound funds in every aspect. .

The global wood pellet market has seen a rapid growth after the adoption of the Kyoto protocol and the renewable energy incentives created within the European Union. The global consumption of wood pellets reached 13,5 million tonnes in 2010 and several experts estimate the consumption to be between 35-50 million tonnes by 2020. These forescasts raise the questions which regions that can supply this vast amount of wood pellets and what the conditions are for producing it. This study evaluates the conditions for wood pellet production and export from British Columbia, on Canada?s west coast, focusing on existing industry structure, raw material supply and the distribution chain.

The point of this study is to present how youths today experience fellowship and deviancy in relation to the different themes that have been chosen to interpret the results. I have treated questions about family, friends, experience of fellowship and deviancy. I have chosen to interview five young adult women and men in order to be able to understand their experiences of fellowship and deviancy. The study has a qualitative approach.In order to be able to interpret the result I have used theories about symbolic interaction, normality and meaning of fellowship. The results show that family is an important part of fellowship and that fellowship means much to form a conception about oneself.

Detta arbete undersöker frågan om hur man kan gå tillväga för att skapa en känsla av liv i en postapokalyptisk spelvärld med hjälp av färger, former och animationer i en egen spelproduktion. Arbetet tar upp flera teorier kring spelutveckling, post-apokalyptisk fiktion och färglära. Arbetet tar också upp verktyg som användes i produktionen av det spel som skapades och hur arbetet fortskred. Diskussionen som följer tar upp hur metoderna som användes påverkade resultatet och vad resultatet blev, samt hur man gick tillväga för att tolka det. Slutsatsen som dras i diskussionen visar att det är möjligt att skapa en känsla av liv i en postapokalyptisk spelvärld i en egen produktion och hur man kan förbättra de metoder som använts i en eventuell uppföljning av detta arbete.

The aim of child health care is to promote health and development for all children, to early identify problems that concern children´s growth and development and to prevent ill-health among children. Today in our society the proportion of children who are underweight are few.The aim with this study was to describe paediatric nurses experience in meeting with underweight children and their parents. Interviews were implemented and analyzed according to qualitative content analysis. Focus was placed on looking at differences and interpretations in the text content. The analyse resulted in six main categories, such as a need of sensitivity and a holistic view from the nurse, difficulties in handling the meeting because lack of tools.

SammanfattningProjektgrupp 14-X5 avser med denna rapport att ge avdelningen Bioreagens på Thermo Fisher Scientific ett underlag för att på sikt kunna byta ut fetalt kalvserum (FCS) mot ett kemiskt definierat suplement vid odling av mushybridomceller för produktion av monoklonala antikroppar. Thermo Fisher Scientific är ett världsomspännande bioteknikföretag som utvecklar blodtestsystem som stöd för klinisk diagnos och uppföljning av allergier, astma och autoimmuna sjukdomar.Fetalt kalvserum är en tillsats i många odlingsmedier som ofta är nödvändig för att cellerna ska växa. Det finns dock många problem med FCS. Det är en biprodukt av köttindustrin och produceras på ett etiskt tveksamt sätt, variation mellan olika batcher förekommer och då det är en animalisk produkt finns en risk för kontamination av bland annat bakterier, virus och prioner. Av dessa anledningar vill man byta ut FCS mot ett kemiskt definierat, serumfritt supplement.

AbstractSierra Leone is a very poor country in Africa. Botswana is another country, that has a similar history and the same deposit; diamonds. Botswana has reached economic growth and democracy and Sierra Leone has not.The purpose with this study is to explain why Botswana is more democratic and has reached a better result economic than Sierra Leone.The questions in this study are:What explains the democratic and the economic results in Sierra Leone and Botswana?* Dahl?s institutions that furthers a polyarchy?* Gunnarsson?s and Rojas? institutional explanations?* Diamond?s and Morlino?s ?rule of law??* Other explanations or a combination of the above-mentioned explanations?The method that has been used in this study is a comparative case study with a qualitative contents analysis. The result is that it?s hard to say that one explanation is the right one.

This thesis investigates techniques for stealth hydroacoustic communication using spread spectrum. The Swedish naval defense organisations have a vision that all their units should be able to communicate with each other, even between underwater vehicles. But the properties of water makes it a complex channel to use for wireless communications. Radiomagnetic waves have very limited range in water, therefore acoustic waves are used. In this report the basics of wireless communication systems are described including source coding, channel coding, modulation techniques as well as different techniques for spread spectrum.

I den här uppsatsen har jag undersökt hur pass-through effekten har förändrats i svenska importpriser på aggregerad nivå och i sju olika industrier. Pass-through effekten definieras som den procentuella förändringen i ett pris som kan härledas till en enprocentig växelkursförändring. Jag har använt rullande regressioner på två olika modeller för att estimera förändringar över tidsperioden 1980 ? 2003. Resultaten visar en nedgång i pass-through effekten i flertalet industrier både på kort och lång sikt.
