This master's theses was carried out on assignment from Stockholm Vatten AB as a part of a project developing new waste water treatment techniques. The goal of the theisis has been to evaluate an anaerobic membrane bioreactor for treatment of waste water from Hammarby Sjöstad. The bioreactor has not been heated and the main interest has been to study the gas production, power consumption and the reduction of organic matter and nutrients.The system has been completed with a reverse osmosis unit and a total of four batch runs have been made with good results. The use of reverse osmosis allows nutrient in the waste water to be reintroduced into circulation as the reverse osmosis concentrate can be used as crop nutrient.The membrane unit is of VSEP ("Vibratory Shear Enhanced Processing") type and an extensive membrane test has been conducted. This so called L-test helped determine the most suitable type of membrane for the system to allow a higher ±ux and thus lower power consumption.

Unit testing is a type of testing technique which is becoming quite fashionable to the developers and companies that are in the business of creating and managing software. Alas there are seldom any concrete data to support the positive claims of the authors in unit testing methodology books. These claims are instead based on empirical studies and the experience of the authors. The problem that arises from this situation is that it becomes problematic for managers and also the developers themselves to convince both customers and their own management to use this type of testing as there is no exact return of investment model. This essay examines this problem from two points, the first point is from the literature itself and interviews conducted with a number of developers at a software company located in Umea, Sweden.

Large amounts of birch-timber are imported to Sweden, from particularly the Baltic States, since the domestic production can?t support the pulp industry. The goal of this study was to show the potential of birch and the area?s most suitable for birch production. The study was limited to Gävleborg County. Using site characteristics, site index (SI) for birch was estimated on all National Forest Inventory plots in Gävleborg County.

Root rot is a big hurter and a huge economic problem for the Swedish and European forestry. The severest hurter is Heterobasidion annosum (Fr.) Bref and it occurs as two different species in Sweden. Commonly referred to as the P-type (Heterobasidion annosum s.s. (Fr.) Bref.) and the S-type (Heterobasidion parviporum Niemelä & Korhonen). Therefore a lot of research has been carried out in this topic to find a solution and reduce this problem, one alternative that have shown to be profitable is stump treatment in thinnings.

This thesis, in the field of healthcare logistics, has been carried out at Hjärt- och Medicincentrum (HMC) at the University Hospital in Linköping during the fall and spring of 2012/2013. The thesis is done by two students at Linköping University at master?s level within the framework of Industrial Engineering and Management.As Sweden's county councils should not make a profit or loss, it is important that the councils are aware of how much care processes cost. Kardiologiska kliniken at HMC in Östergötland?s county council is one of the clinics that are profitable.

In the Swedish market, there is a wide selection of herbs as supplement to the horse´s feed. A trend today is that many companies are marketing herbal remedies with allegations of medical effects. If you want to sell the product for that purpose it must be verified and approved as drug or natural remedy by the Medical Products Agency. Some herbs may contain active substances. Nevertheless, only a few studies have been conducted on single herbs to investigate safe doses for horses.

There are mainly two ways to transform the design of an existing park. You could either make a replanning of the park, an act that changes the design and the plant material in one swoop. Or you could use the management to change the expression of the park. To be able to develop the parks with the help of management, some form of goal is needed, that can make the management of the park strive towards an expression for the whole park as well as its individual parts. Among the documented goals, for individual parks and park management, which exist in the municipalities today, there seems to be a weak link between the all-embracing goals and the management that is carried out in the parks.

This analysis recommends not to use Windows Server 2008 without properevaluation in any system containing classified information. The reasons are too lowassurance and too weak authentication. If Windows Server 2008 is to be used itshould be supplemented with a stronger authentication mechanism. The installationshould preferably be of Server Core type and the server should be maximallyhardened..

This paper contains an analysis that sets out to investigate how sustainable development is portrayed in textbooks used in gymnasium level civics education. The study covers three textbooks, all in current use. The paper sets out to explore the relationship between the books chapters on economics and those about environmental issues. The sum of these two parts is in the context supposed to make up the books big picture of green sustainable development, i.e. the ecological aspect of sustainable development. An analytical model will be used to categorise and compare the three textbooks.The method chosen for this is analysis of ideas by use of ideal types.

Background: When companies decentralize their operations into profit centers, transfer pricing often becomes an integral part in intracompany trade. A profit center may affect both revenues and costs and seek to maximize profit. Transfer Pricing is a complex subject because it is affected by a large number of factors including the profit centers will to generate profits. This leads us to the subject of decision-making in a transfer pricing-systems. On what grounds are decisions made? Are transfer pricing purposes, factors and interests taken into consideration? What type of information is used in such decisions, how is the transfer price issue perceived and how is it used?Aim: The purpose of this thesis is to analyze which type of information that is makes up transfer prices, how the transfer price is perceived by different parties and how it is used for decision-making.Completion: A qualitative study has been performed with current theory as a starting point.

The aim of this essay is to study the importance of team organisation of teachers? learning of teaching and learning and to find out different obstacles and possibilities.I carried out the study at a schooldistrict in a community in the south of Sweden. Data was collected by group interviews and document studies. To get all kinds of teachers, from pre-school to year six, in the groups the sample was made by the headmaster of the schooldistrict. Since it is a case study the findings can not be considered as general, but they can hopefully contribute the pedagogical discussion and future research.The findings show that there exists a difference between the expectations on policy level on the one hand and on the team level on the other hand.

This study focuses on a specific organization of a Security Operations Center (SOC) as a case studyto first identify specific challenges related to the work process, preceding with identifying whichprinciples from various process models, such as agile and traditional methodologies from softwaredevelopment companies, can be implemented. Initially, the study presents relevant research on agile and traditional process models as well asresearch on SOC. Subsequently, six semi-structured interviews are planned and conducted withemployees within a specific SOC-type organization to identify the current work process and thechallenges affecting the organization?s work process. The results of this study indicate a description of the current work process in the organization aswell as a variety of challenges related to technical and organizational issues.

The purpose of this research is to examine how a ogranization can create Word-of-Mouth and how they can use this type of marketing to make their brand stronger..

A secondary and a pioneer tree species can with advantage be included in a mixed stand to increase the use of sunlight. Nitrogen-fixing plants have been shown to increase the supply of nitrogen in the soil by, for example, litter fall. This deposition acts as a biological fertilization, which may be used by non-fixing plants. Alder is a nitrogen-fixing, pioneer tree species that loses its nitrogen-rich leaves late in the autumn. The aim of this study was to examine the effect on the total volume of production, when different proportions of nitrogen-fixing Alder were part of spruce stands.
