Oxochlorates are anions with a partially naturally occurrence in nature but are also spread by human activities, including the paper industry. These compounds are harmful to both nature and humans, which makes it necessary to find a good way for their degradation. There are two different kinds of bacteria that can use oxochlorates as electron acceptors in their metabolism, bacteria that break down perchlorate and bacteria that break down both perchlorate and chlorate. A bacterium that can break down chlorate under anaerobic conditions is Ideonella dechloratans which holds the genes for chlorite dismutase and chlorate reductase which are enzymes for the degradation of chlorate. Gene expression and enzyme activity of chlorite dismutase are induced under anaerobic conditions, which makes it interesting to find out how this regulation functions in order to better exploit these bacteria in biological wastewater treatment.

Background Children spend much of their time outdoor at preschool. Preschool's mission is to provide children with a rich environment that is enjoyable, and that arouses their interest to learn new skills. Since motor skills and health are positively affected by the outdoor environment should kids get a good turnout at their preschool playgrounds as possible.Theoretical perspectives My study is based on theories from a socio-cultural perspective. The socio-cultural context is part of the outdoor environment because we experience and perceive nature depends on the society we live in and how we interact togetherPurpose I want to see what kind of vision teachers and parents have on the outdoor environment when it comes to children's learning and development. I also want to find out how the teachers are using the outdoors environment and find out the parents' reason, when it comes to choice of preschool.Methodology The work is based on qualitative interviews with two teachers and two parents from each preschool.

Hur åldersstrukturen i ett land påverkar den ekonomiska tillväxten i Sverige är en aktuell fråga, då den svenska befolkningen håller på att bli allt äldre. Det kommer att påverka ekonomin på flera sätt. Uppsatsen syftar till att undersöka hur förändringar i den svenska åldersstrukturen har påverkat den ekonomiska tillväxten i Sverige, samt försöka ge en fingervisning om hur de framtida förändringarna kommer att påverka den ekonomiska tillväxten. En regressionsanalys med förklarande demografiska variabler genomförs för att utreda hur den svenska åldersstrukturen har påverkat den svenska ekonomiska tillväxten. Regressionsanalysen är gjord efter inspiration av en Solow-modell som har utvecklats med demografiska variabler.Resultatet visar att olika åldersgrupper påverkar den ekonomiska tillväxten på skilda vis.

A large number of farms within the agricultural sector will shortly be facing a point of time where the farm will be transferred to the next generation. The grantor can choose between totally 8 different strategies to transfer the farm, of which purchase, gift and a mixed form of these are the most common. During 2007 almost 10 000 transfers of agricultural estates occurred in Sweden and the expectation for the coming years is that about 15 000 estates will be transferred each year. By the time a transfer is about to materialize there are usually several stakeholders that in one way or another is trying to influence the outcome of the transfer. The choice of transfer method affects the conditions and possibilities for compensating the siblings.

The purpose of this study is to investigate how power is distributed in the mathematics classroom and how students achieve agency when ICT (Information and communication technology) is used as a teaching tool. Three learning situations, structured by mathematics, are analysed: in the first situation mathematics is taught in a traditional way, in the second mathematics is taught in interdisciplinary projects, and in the third mathematics is taught using ICT as a pedagogical tool. The theoretical concepts of power and agency are used as analytical tools within a socio-political framework. The concept of power is used to assess the students? ability to influence their learning and degree of inclusion in the three learning situations.

The main purpose of this C-essay is to answer the question: What have been the consequences and effects of the merit point system on language studies and the parties concerned (teachers, students and principals) during the school year of 2010/11?The merit point system is the result of a political decision and was implicated for the first time in the Swedish upper secondary school during the school year 2010/2011. Being a completely new phenomenon it is of great interest and importance to study its effects.The study in this essay also aims to verify, falsify or nullify two hypotheses very often referred to in the political discussions regarding the merit point system:The merit point system will replace affection and interest as main reasons for language studies in upper secondary school and cause a rectification amongst the students choices of additional courses.The merit point system will have a segregating effect upon society and make it harder for people to rise in society through education in the future.A verification of these hypotheses would imply the appearance of an increased rectification amongst students as well as an orientation towards an in the future more segregated society.The empiric material has been collected and examined with qualitative as well as quantitative methods (questionnaires and interviews) and belongs epistemologically to the phenomenological and hermeneutical traditions..

The Swedish agriculture has gone through some changes and there are more changes coming in the near future. The structure is mowing towards bigger units.

Predatory pricing is one of the most frequently discussed topics in competition law and should be considered both from a legal and economic perspective. The concept of predatory pricing can bedescribed as a situation where a company is pricing at a level that, according to the assessment theories, is unreasonably low. The problems with this type of conduct arises when the low prices hinder competition. A company which uses predatory pricing will likely deter rivals entry to the market or drive the existing ones out of it. In the long run, the effects on competition will likely be higher prices which will hurt customers and consumers as well as competition.

The purpose of this thesis is to examine whether the teacher's background affect students' approach to mathematics teaching. Characteristically, in Sweden today is that mathematics is perceived as difficult subject and that the number of foreign teachers has increased. The study examines a phenomenon which the relationship between the teacher's language accent and substance difficulties.The method used for data collection is questionnaires, in order to investigate the phenomenon as the relationship between the teacher's accent and substance difficulties.The investigation has been carried out based on the students' point of view, both secondary and primary school pupils. What difficulties have arisen in teaching?  What is the biggest obstacle to achieve the goals of mathematics, to understand the teacher's language accent first in order to understand the subject, or that mathematics is difficult in itself to be understood as a substance.The result clearly shows that the teacher's accent does not affect teaching and students' view of mathematics as a subject.

SIDA?s relief work in Bosnia aims at making the country ready for a membership in the EU where the main focus lies in the creation of a sustainable state as well as liberalizing the market to create an increased economic cooperation between Bosnia and the rest of Europe. These ambitions are closely related to the neo-liberal theory of state building which aims at creating democratic societies in line with the western democracy model, with a liberal economy constituting its base. Despite generous financial aid, the democratic and economic development in Bosnia is moving very slowly and the ethnical tensions seem to grow despite international involvement in the country. The purpose of this study is to evaluate SIDA?s present relief work in Bosnia out of a peace perspective.

Introduction/Background: Economic evaluations help decision-makers to make informed decisions regarding resource allocation.

Objective: The aim of this thesis is to investigate the use of economic evaluations in public health, with a focus on CEA. Use of economic evaluations is regarded as both a method for evaluation and as support for informed decisions.
