Abstract My purpose of doing this study is to investigate the culture of delivering education in a strange combination of subjects labelled ?Language choice Swedish/English?. The activity however exists without curriculum, syllabus or certification. I want to put study the problem of delivering an educational activity without national certification. I will use a hermeneutic approach and render properly the headmaster?s, the teachers? and the students? views on the activity in one school.

The upstream spawning migration of Atlantic salmon (Salmo salar) at the confluence area between the power-station outlet and the bypass-channel in river Umeälven (flow 430 m3s-1) was compared in 2004 and 2005, two years with different experimental flow-regimes. In 2004 the water flow in the bypass-channel was altered during the day with increased flows during the nights while the water flow in 2005 mainly was altered between the weekdays and weekends. Salmon showed altered migratory behaviour in this confluence area, assessed with telemetry (n=116) and echo-sounding, with up- or downstream responses depending on flow-changes in both the bypass and the power station outlet. Increased turbine flow through the power-station generally attracted salmon into the tunnel outlet area while increased spill-flows facilitated salmon to enter the bypass. Echo-sounding in the confluence area showed an increased swimming activity up- and downstream due to time in the day and flow-rates through the tunnel outlet. No changes in activity could be detected due to increasing or decreasing flow through the hydro-power facility.

Aim: The aim with the thesis was to examine elderly peoples? motives towards physical activity. Method: A qualitative approach has been adopted with a purposive sampling procedure. Four half structured interviews have been conducted using a thematic interview guide. Results: The fear of being overweight and not being able to take care of themselves were announced as important aspects, since it motivated them to perform physical activity.

Water is the most essential resource for life. In cases where drinking water is processed from surface water it is important to ensure the raw water is of good quality, and is suitable for processing through the water treatment plant.The drinking water for Västerås is sourced from Västeråsfjärden, in the western side of Lake Mälaren. The city itself is home to marinas, ports, a wastewater treatment plant, the Svartån outlet, sewage pumping stations and stormwater outlets. Because of the negative effects these activities have on surface water quality, Mälarenergi AB is interested in relocating the raw water intake point to Granfjärden, 10 km east of Västeråsfjärden. At Granfjärden the intake point would be less exposed to the activities in Västerås, and could be placed at a greater depth, resulting in better water quality.In this Master?s thesis the water quality and the pollution risks at Västeråsfjärden and Granfjärden sites are compared.

The focus of this study was to examine the nutrients and benthic organisms of the bay ?Mönsteråsviken?, which is influenced by eutrophication. The purpose was also to look at an interesting gradient forming in the bay, namely the distance from the river outflow of Lillån. At 18 sampling sites in the bay samples of water, sediments and benthic organisms were collected in late April of 2011. The water was analyzed for nitrate, phosphate and chlorophyll.

The average life expectancy and the proportion of elderly are increasing globally and inSweden, causing challenges for the society. Physical activity has proven to bring a number ofpositive benefits in older people, making the promotion of physical activity an important partof healthy aging attempts. The degree of physical activity in Sweden?s elderly population isgreater than in previous generations, making this group a positive exception from a widerperspective. A cross sectional study was made in order to investigate which motives tophysical activity that was considered most important among people above 60.

AbstractDancing and the body`s ability to express itself has been an interest of mine for a long time. For that reason I would like to find out more on how you as a pedagogue can work with dancing as a way to develop motoric activity. The purpose of my research is to find out how pree-school-pedagogue`s and sportsteacher`s are working with dancing, and also how children in a pree-school class apprehends the idea of dancing before and after a dancelesson.My question for this paper is:How can dancetutoring in pree-school develop children`s motoric activity?To find out the answer for this question I have also chosen to use relevant litterature within the subject. Since the examination covers only the answers from four pedagogue`s and six children I can not make a generell conclusion that covers all children or pree-schools.

Background: The population of the world is getting older and in the year of 2020, 1.2 billion people will be 60 years or older. A common health complaint affecting the quality of life in elderly persons are sleep difficulties. Physical activity is claimed to improve sleep quality and the maintenance of a normal circadian rhythm. Several studies have shown positive effects of physical activity on sleep quality, still the evidence of physical activity as sleep-promoter is insufficient. Aim: The aim of this study was to investigate associations between physical activities and sleep quality in persons ?60 years of age.

The aim with my master thesis is to develop and test the applicability of methods to quantify and map solute advective travel times and pollutant transport at the catchment scale. Such quantification and mapping can increase the understanding of catchment-scale pollutant transport in general and contribute to the identification of the main sources of water pollution and the most efficient measures to reduce such pollution. The study area is the catchment of Oxundaån, about 20 km north of Stockholm. For detailed GIS modeling of water flow and catchment-scale contaminant transport in water, I´ve used new high-resolution elevation maps, land cover maps and soil maps combined with other available relevant data..

ABB I-R Waterjet Systems combines the robotics and motion expertise of ABB Flexible Automation with high-pressure intensifier/pumping technology from Ingersoll-Rand to provide and continue to develop innovative waterjet cutting systems for global markets. The purpose of this assignment is to develop a process water purifier. The purifier should be applicable as an option to ABB I-R?s production cell Cutting-Box. At first hand the process water should be purified well enough to let out in the municipal sewage system, but the ultimate solution is purifying the process water to the range that recycling is possible. When investigating the different principle of purifying water, a research of different products and their manufactories was done. These different products were compared and the principle of filtration was the most applicable, as most of the products were designed for far larger applications. As the process water contains quite large amount of particles, it is necessary to perform the filtration in different steps. The process water purifier is therefore composed of a module of coarse filtration and one of micro filtration. In the module of coarse filtration the mainly amount of fibres and particles are eliminated. They are kept back in the container unit with the larger fragments and dumped with these when the container is emptied. In the module of micro filtration the filtration is performed in two steps. In the first step particles larger than 50?m are eliminated, in the second step the micro filter is setting the range of purifying, in this case 10?m.

AbstractThe purpose of this investigation is to find out how the pupils can discover and to feel joy in their creative art activity and also to believe in their own ability. The aim is to figure out if creative art activity is able to raise the pupil?s self-image. By literature, pedagogue interviews, and interviews with pupils at the age of ten years old and by action research is the way that I have searched for an answer for my question. The main result is that fantasy, creativity, courage and lust are important parts to develop in the job of raising the self-image.

Ocean Thermal Energy Conversion (OTEC) is a technology that utilizes the temperaturedifference in oceans between the warm surface water and the cold water at 1000 m depthto produce electricity. The purpose of this report is to investigate if OTEC with its synergiescould become a commercially feasible energy solution for a small island. A literature reviewis conducted to explore the different OTEC technologies and to what extent the threesynergies; fresh water, air conditioning and aquaculture, could be used. In order to calculatethe profitability of these synergies there is also a study conducted on the conventionalmethods and cost of fresh water production, aquaculture and air conditioning. A model is setup using a scenario of a small tropical Island with population of 100 000 people.

Perfluorinated substances (PF) are environmental pollutants that are used to coat fibres of so called ?all weather clothes? to make them water resistant. PF are effectively spread through water. Waste water treatment plants (WWTPs) are a pollutant source of these substances. PF are poisonous to different kinds of organisms, and supposedly also to human beings, if concentrations are sufficiently high.Perfluorinated substances have been investigated at three waste water treatment plants in Stockholm during the 2000?s.
