The world?s growing need for energy together with a desire to ward off the worst consequences of global climate change has resulted in a never seen desire to invest resources in renewable energy sources. Biogas production through anaerobic digestion is one of those growing energy sources. In Sweden there are over two hundred plants that uses this biological process to break down organic substances while producing carbon dioxide and the energy-rich gas methane.This master?s thesis has focused on development of the mixture of different organic substances that is treated at a specific plant, namely Mosserud biogas plant.

Den här uppsatsen behandlar Sveriges narkotikapolitik, och då i förlängningen dess inverkan på individen, i form av missbrukaren. Syftet med föreliggande studie är att spegla individperspektivet i den aktuella narkotikapolitiska debatten, för att se hur missbrukarens position i samhället kan tänkas se ut framöver. Problemställningen utgår ifrån att politiken leder till att missbrukaren starkt marginaliseras i vårt samhälle, då målet om "det narkotikafria samhället" utestänger användaren av narkotika.Uppsatsen bygger på Foucaults teoretiska begrepp makt, disciplin, avvikelse och norm. Samt på det perspektiv man inom rättssociologin benämner normvetenskap. Utifrån dessa begrepp har en teoretisk modell skapats, som hjälpmedel vid genomförandet av undersökningen.

The aim of this study was to describe and to analyze needs and social efforts concerning unaccompanied/separated asylum-seeking children. The responsibility for the reception of this target group was transferred on July 1, 2006 from the Swedish Migration Board to the municipalities that sign an agreement with the Swedish Migration Board. Eight qualitative interviews were carried out with representatives for transit-residents and assigned municipalities in Skåne. Our main questions were: How has the reception of unaccompanied/separated asylum-seeking children been planned, how do the municipalities and the transit-residents consider their needs and what is the level of qualifications and competence within the municipalities in order to work with unaccompanied/separated asylum-seeking children on the basis of social efforts? We chose to clarify our findings on the basis of the attachment theory, which is applicable during the critical emancipation phase that the vast majority of the unaccompanied/separated asylum-seeking children find themselves in.

The society has always tried to get rid of those who do not "fit in". They doesn't follow the normal behaviour and rules and have to be "dismissed". The community has developed different kinds of institutional care for individuals with dysfunctional behaviour. Those institutions are mental hospitals and prisons. Many of these institutions put the individuals in an extreme situation since they loses their independence and freedom.

The purpose of this study was to examine whether the success of theconcept of empowerment in the field of social science can be explained by referring to it as the new paradigm replacing the former paternalistic era. Therefore, I investigate if the character of its history, domicile and practice has the same distinguishing features as the scientific progress. The analysis is based on Thomas Kuhn's definition of a scientific paradigm through the concepts of consensus, crisis and revolution. I also look for alternative ways to explain the sudden appearance of empowerment at the world agenda. Due to the lack of a uniform definition of the concept and the absence of common approaches in the stimulation of empowerment it's difficult to argue that the situation is marked by consensus.

Aluminium sulphate (Al2(SO4)3) is usually added during the drinking water treatment processin order to precipitate organic and inorganic material, resulting in aluminium-based drinkingwater treatment residual sludge (WTR). Since 2003 Swedish law no longer permits WTR tobe deposited in lakes, and there is an interest to explore the possibility to utilize WTR as soilamendment. The aim of this study was to examine the effects of WTR application on cropgrowth and concentrations of macronutrients and trace elements (including micronutrients andpotential toxic elements). A greenhouse pot experiment was conducted with three soils; a clayloam rich in phosphorous (P), a loamy sand rich in P, and a silty loam with a low soil Pconcentration, and two crop species Italian ryegrass (Lolium multiflorum Lam. cv.

Bakgrund: Studien tar utgångspunkt i den nya kursplanen för matematik där matematikens användning i olika sammanhang och vardagen betonas tydligare än i den förra kursplanen (Skolverket 2011a; Skolverket 2011b). Elevers sjunkande matematikprestationer är en pågående problematik (se. t.ex. TIMSS 2007) och förhoppningar med denna rapport är att lyfta en bredare syn på matematik och därmed skapa motivation för eleverna. Ambitionen är att framhäva en matematikundervisning som anknyter till vardagen och elevernas erfarenheter.Syfte: Syftet är att undersöka hur elever i skolår tre uppfattar matematik.

The purpose of this essay is using theories about labeling and social bonds to study whether a measure of rehabilitation for the psychically disabled contributes to a return to a normal status as not-labeled. Partly we examine whether the activities organized by the regulation-ruled authorities during the work of rehabilitation lead to shame or pride, and partly how these activities are organized regarding the processes that lead to the emotions pride or shame among the participants. Method: qualitative semi-structured face-to-face interviews with professional rehabilitation-actors at the Public Employment Office (PEO), the Social Insurance Office (SIO), the Social Service (SOS), the Psychiatry and the Division of Labour Market (AME).Conclusions: the Psychiatry clients are treated with respect, may participate, and communication is characterized by attunement, therefore strong social bonds can be built. On the contrary, among the other examined activities, we found many elements that arouse shame. Since these are more ruled by regulations, the result is engulfment and demands on conformity, because the compromise-possibilities are almost non-existent.

The dairy market will change importantly in the coming years. The quota system, which has regulated the European dairy production, will disappear in 2015 and the European dairy market will then be importantly affected by the volatility characterizing the dynamic of world prices. Besides this, the global demand of dairy products is expected to increase due to the growing world population. Farmers in countries such as the U.S. and New Zealand, when compared to Swedish farmers, show greater familiarity and experience with risk management tools.

The aim with this study has been to examine and to analyze the discourse of Rosengård in Swedish media. With the concept of discourse is meant here specific ways to speak about and to understand the world, or a part of it. In order to reach increased understanding regarding media presentations and constructions of Rosengård, I have done a study about how Rosengård has been presented in the Swedish daily and evening press during the violent acts that took place in Rosengård in the spring and summer of 2008, when youths regarding to media put cars and containers on fire, and also threw stones at fire engines and other emergency service vehicles when these had to turn out to put out the fires. The collected data, containing newspaper articles, has been analyzed on the basis of the critical discourse analysis, CDA, which is a mould of a textanalytical method. This study applies a social constructivist perspective.

Syfte: Att studera vilka faktorer kunder tycker är viktiga vid val av bank och försäkringsbolag. Att se hur väl företagen känner till kundernas preferenser vid val av respektive tjänsteföretag samt att se vilka likheter och skillnader det finns vid val av 2 tjänsteföretag inom den finansiella sektorn.  Metod: Undersökningen gentemot kunderna genomfördes med hjälp av en enkätundersökning och personliga intervjuer vid respektive tjänsteföretag. Enkätundersökningen har redovisats i form av diagram och tabeller medan intervjuerna har redovisats i löpande text. Resultat & slutsats: Kunderna ansåg pris, räntor, ett bra bemötande och engagemang samt personalens kompetens vara viktigast vid val av både bank och försäkringsbolag. Bankkunderna ansåg att närhet till banken och att ha en bra relation till banken var viktigare än vad försäkringskunderna tyckte.

Herbicide resistance is the result of an evolutionary process where a population gradually changes from being susceptible to being resistant to an herbicide. The resistance mechanism is usually a change in the biochemistry of the weed, but in some cases changes in morphology or growth rhythm. The change is caused by random mutations. Two resistance mechanisms are found in black-grass; target site resistance and metabolic resistance.Black-grass is a tufty, winter annual grass weed, which is mainly found in milder climates. Black-grass is a big problem in Southern Europe.

The purpose of this paper is to examine what problems cabbage growers have with the Swede Midge. The last few years the Swede Midge, Contarinia nasturtii, has become a larger problem for cabbage growers in several countries in Europe as well as in Sweden. In Canada the problems are so severe that the midge is classified as a quarantine pest and therefore certain rules have to be followed. I have collected facts of the biology, host plants and reproduction of the Swede Midge, as well as the growers experiences and the occurrence of the midge in Canada, Europe and Sweden. The Swede Midge is hard to control because of its short life cycle and the larvae are protected between the heartleaves of the plant. When the larva feeds on the growth point the plant becomes distorted, in some cases several heads develop or none at all. When the midge infests spring rape its flower buds become undeveloped and rosette like.

To investigate the possibilities for effective soil tillage, that could imply lower costs, lower negative environmental impact and in addition a meaningful occupation for foraging pigs, a field experiment was carried out in Gränna, Småland, during growing season 2006. The experiment contained two treatments that were repeated three times and were carried out on a couch grass-infected fallow on a light soil close to Sweden?s second largest lake, Vättern. Ploughing was one treatment and pig rooting followed by ploughing, was the other. The experiment was conducted according to the guidelines of organic growing and seedbed preparation was done the same way in the two treatments. The pigs, three groups of five half-year old Linderödssvin (an old Swedish breed), was encouraged to perform an even tillage by strip-grazing, i.e.

To curb greenhouse gases and mitigate climate change is one of the biggest challenges human society face today. Carbon dioxide (CO2) has accumulated rapidly in the atmosphere as a consequence of burning of fossil fuels and deforestation. The aim of this study is to explore two methods to store carbon dioxide in geological formations and biological sinks. The aim is also to discuss the two mitigation options from a sustainable perspective and whether it can lead to a better environment and benefits for local and global societies. The research questions are: Which method to store carbon dioxide, geological or biological, is the most effective? Which method to store carbon dioxide, geological or biological, has the greatest potential to promote sustainable development for local communities?The method used is a comparative case study and presents four case studies that explore the potential for CO2 storage offshore in Norway and Brazil; and in tropical forests in Mexico and Brazil.
