The purpose of this study was to evaluate the different substrates that enter the digestion on Sundet wastewater treatment plant for production of biogas.This work have done an analysis of data about the biogasproduction from January 2012 to feburari 2013, this showed that the food substrates has a greater gas production than internal sludge.Through laboratory test the VS, TS and COD values for all the substrates used in the biogas production could be determinded. But the COD-method was less optimal for analysis of fat and food, therefore it optimized the method for fat but due to time constraints, this could not be done on the food substrates..

In this literature review the characteristics of two free-floating macrophytes, water hyacinth   (Eichhornia crassipes) and duckweed (Lemna sp.), and two microalgae, Chlorella and Scenedesmus, have been examined regarding their suitability as efficient nutrient removers in the treatment of wastewater with high levels of nutrients and suspended solids from a biogas plant in Loudden. The needs required for the plants to be able to grow in wastewater and the amounts of biomass they can produce have also been studied. The results show that Chlorella is capable of a very high uptake of nutrients in photobioreactors with high nutrient loadings. With an ammonia uptake maximum value at 10900mg/m2/d Chlorella outshines the other organisms in this study. The test organism that performed the closest to Chlorella in terms of nitrogen uptake was water hyacinth with an uptake about 1602mg/m2/d.

An analysis of a specific application of anaerobic wastewater treatment at a pulp and board mill, Stora Enso Skoghall, was carried out. A literature study was done and effluent wastewater from CTMP pulp production was analyzed. The analysis consisted of a broad constituent analysis and an anaerobic treatment trial. Results from these test where used to calculate the treatment effectiveness and resulting energy potential at the mill.The literature study and constituent analysis showed that toxicity of the water to be treated, due to wood extractives and sulphur content, was of concern. Detoxification chemicals targeting these constituents where used in the anaerobic treatment trial.

The purpose of this thesis is to investigate if elementary school teachers are a vulnerable professional group and if elementary school teachers should be mentally prepared for abusive treatment. Thus determine whether the reduced possibility for certain professionals such as police officers and order guards to obtain compensation for abusive treatment also shall apply for elementary school teachers.To reach that purpose, first the concept of abusive treatment and how compensation for abusive behavior becomes topical have to be straighten out. Then follows an analysis of both the lower possibility to obtain compensation for abusive treatment, but also how elementary teachers can be mentally prepared abusive treatment.It turns out in the conclusion that elementary school teachers are considered vulnerable in relation to the specifications of their work environment and because of that elementary school teachers must be deemed to have knowledge of that they may be subject to abusive treatment. Therefore I believe that elementary school teachers as certain professionals like police officers and order guards may not be granted compensation for every situation of abusive treatment, a lower limit must apply..

This diploma work covers an investigation over the heat - and hot water systems of thetenant-owner's association, Bogården. The heat - and hot water needs of Bogården aresatisfied by both district heating as well as three heat pumps. Implemented investigationshows that the heat pumps are not used in a profitable way. Apart from that, the reservepossibilities are small. There is also a risk of the growth of Legionella bacterium in thehot water system.Since the heat pumps are already installed, HSB-Gävleborg (responsible for Bogården)has a wish to investigate possible proposed actions for optimization of existing plant.After completed investigation, a new proposed action is presented.

Background: Chronic pain is a condition that approximately 18% of the Swedish population suffers from. This condition affects many aspects of a person´s life and causes psychological, physiological and social suffering. Multimodal treatment is considered the most effective treatment for patients with chronic pain. Patient participation and motivation are very important to treatment. Aim: The aim of this study was to explore patients´ experience of a multimodal chronic pain treatment program regarding their experience of patient participation and interaction with the rehabilitation team.

Burnt alun shale and lime is the residual product that was formed when alun shale was used as fuel to convert limestone to quick lime. The material contains arsenic, vanadium, molybdenum, cadmium, nickel, lead, and uranium among other elements. The aim of this paper is to examine the uptake of trace elements in vegetables grown on burnt alun shale and lime to determine whether or not the surrounding environment and humans are exposed to these elements by eating plant products. A cultivation trial was carried out where onion, carrot, and lettuce were grown on three mounds of burnt alun shale and lime in the Falköping area in Sweden. The treatments were burnt alun shale and lime mixed with peat, only burnt alun shale and lime, and a reference soil. The reference plots were natural soil mixed with peat adjacent to the mounds.

Meat and fish was the most important food for the Sami people in northern Scandinavia until the beginning of the 20th century. It is not so well known that the Sami people also used a lot of wild plants as food and medicine although that kind of food was relatively common among them until the end of the 19th century. The purpose of this master thesis has been to describe which plants the Sami people used in general and also which plants were the most commonly used, and when and how these plants were harvested. I also wanted to measure the quantities of Angelica archangelica and Rumex acestosa within traditional harvest sites. Furthermore I wanted to find out if the plant use differed among Sami groups geographically.

Growth of small businesses is vital to the Swedish economy, and many entrepreneurs want their enterprises to grow. However, the business climate of today is more changing than ever, and attributes becoming increasingly important for companies in order to deal with this are flexibility, speed, and adaptability: characteristics normally attributed to small enterprises. As a larger organization often is associated with more rigidity as a consequence of a higher degree of formalization, entrepreneurs are hesitant to seize growth opportunities, as they fear it will have negative impact on the aforementioned competitive advantages their enterprise possesses as a small business. This simple case study of a growing small enterprise investigates the effects of organizational growth on a small business' organizational structure and through its above mentioned advantages. The study finds that avoiding formalization while growing damages the competitiveness of the firm, and concludes that a degree of formalization is a necessity to maintain the flexibility, speed and adaptability in a growing small business..

This study deals with the technical and economic feasibility of replacing the nuclear power plant reactor Ringhals 3 with a biofuel power plant. A technical investigation has been executed to determine which of the systems and components that could be reused and which ones would need to be replaced. The investment costs of the reconstruction have also been estimated. The cost of the electricity production has been calculated as well as the emissions of the new biofuel power plant. Based on the established rate of return, the lowest average spot price of electricity that makes the investment profitable has been calculated.

Overweight and obesity among children and adolescents is increasing. Diseases which earlier occurred exclusively among adults are now also observed among children. There is an urgent need for new treatments that can change this negative trend. The aim of this study was to describe existing treatments for obesity among children in the age of 6-12 and the effect of those treatments. This descriptive literature study is based on 17 research articles published between 2000 and 2007 from different parts in the world.

The aim of this essay is to examine which help a group of women with eating disorders had from thier treatment in daycare in 2004. The aim is to examine how the women have experienced this treatment and how they live today. The central questions are: what was their life situation like before the treatment, what was their experience of the treatment, how could the treatment have been better and how are their lives today? The method is based on qualitative interviews with seven women who were all in the same treatment for eight weeks at Capio AnorexiCenter in Malmö. The women have also redone tests that were done right before and right after the treatment.

In this study we have investigated how care users in a nursing home experience their possibilities for influence and treatment from the staff. The study was conducted through focus group interviews with six participants who we met on four occasions. Questions the study departs from are: How do users experience their opportunity to influence? How do the users experience the treatment from the staff? The study has a qualitative approach and has been analyzed by means of symbolic interactionism, with an emphasis on the Self. Our results demonstrate that in situations of good treatment there is also a good influence.
