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 EU's Water Framework Directive aims to a long-term and sustainable use of our water resources and wants to ensure good water quality in Europe's water bodies. Discharge of polluted stormwater into receiving waters can be a threat to their ecological and chemical status. Municipalities are responsible for supervision of the environmental quality standards (EQS) and therefore need to gain knowledge of current stormwater management, the expected level of pollution emissions and possible appropriate purification steps to ensure that the goal of good water quality is achieved.This master thesis aims to provide this knowledge in the example case of Vallentunas urban area and wants to prepare future oversight so that it can be assessed how much the discharge of polluted stormwater into the local receiving water is a threat to its status. With the help of maps, aerial photographs, site observations and individual discussions those areas are mapped where appearance of moderate to highly polluted stormwater could be suspected. The degree of pollution at the discharge points is determined based on land use upstream and uses standard values according to the administrators assistance "Tillsyn av dagvatten" (MSL 2014).The study identifies 100 areas in need of supervision regarding their stormwater management.

The Yangtze finless porpoise (Neophocaena phocaenoides asiaorientalis), is a small freshwater cetacean which has recently fallen dramatically in number. It is an endemic species for the Yangtze River and unless drastic action is taken, it risks the same fate as the now functionally extinct Yangtze river dolphin (Lipotes vexillifer). Threats to the porpoise are diverse but they have in common that they are caused by man. Development of the river has been made to supply a growing human population with food, hydropower, and to reduce the risk of flooding. These changes have resulted in a degraded habitat for the porpoise.

The aim with this report is to investigate what influence the way playgrounds are used throw the case study in Vänersborg, and also to find methods for municipalities to collect information about how playgrounds are used. The methods were observations, interviews with parents and children, a questionary with questions about what playgrounds they used, how often and why they used them and what the children used to do there. There was also a demographic investigation and documentary research. The most popular playground, Skräcklan, gets visitors from all parts of the municipality. It is located in a park with a view over the lake Vänern, there is a parking place and a café and it has furthermore a large area and many play equipments. Many of the families make shorter trips and picnics to this place. In exception of this playground, the families almost always go to the playground in their neighborhood and their part of the town.

Ammerån which is a small forest river in eastern Jämtland is a well-known river that has been a popular fishing river for a long time. The actual Ammerån begins downstream the lake Solbergsvattnet at Hammerdal and flows into the Indalsälven 10 km upstream Hammarstrand. The river environment switches between forests with wilderness feeling and open agricultural land. The entire Ammerån is today a nature reserve and protected from hydropower development. Fishing in Ammerån has mainly been focused on trout and grayling, and is so even today.

Österbyverken is an industrial estate in Östhammars municipality in Uppland, Sweden. Many different activities have taken place on the estate the last 600 years. During the last 15 years both health and environmental studies have been made by different companies. At the most recent study a great increase of metals in Nerån, a river that runs partly through and partly next to the estate, was identified with mass balances. The purpose of this thesis is to accomplish a deepened study about the reasons for the increase of metals in Nerån.

SammanfattningTitel:En kvantitativ studie om kapitalstrukturen i två branscher med olika risknivå ? efter första verksamhetsåret.-Jämförelse mellan bolag i fastighet- och tillverkningsbranschen.Nivå:C-uppsats i ämnet företagsekonomiFörfattare:Christoffer Blomqvist och Martin HammarstenHandledare:Arne Fagerström och Annika LakeDatum:Maj 2013Nyckelord:Företagsfinansiering, kapitalstruktur, soliditet, soliditet 2, skuldsättningsgrad, eget kapital, räntebärande kapital, risk.Syfte:Syftet med denna studie är att undersöka kapitalstrukturen i tvåbranscher med olika risknivå, för att sedan jämföra branscherna och undersöka om kapitalstrukturen skiljer sig åt mellan dem. Studien undersöker även faktorer som påverkar företagens val av kapitalstruktur i de båda branscherna.Metod:Uppsatsen har sin grund inom det vetenskapliga ämnesområdet företagsfinansiering. Studien har genom en kvantitativ metod utfört en dokumentstudie i databasen retriever, där siffror och nyckeltal har hämtats genom årsredovisningar från bolag inom studiens två branscher. Resultaten från dokumentstudien har kopplats till innehållet i studiensreferensram och sedan analyserats för att komma fram till en slutsats.Resultat och slutsatser:Resultaten från denna studie visar att branschen för uthyrning av fastigheter har en kapitalstruktur som är betydligt mer viktad åt belåning gentemot branschen för tillverkning av maskiner/maskindelar, efter första verksamhetsåret.

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.

The municipality of Västervik, with support from Envipro Miljöteknik AB, is carrying out a main study of the minefields at Gladhammar. Mining of iron, copper and cobalt under different periods from the 16th century until the end of the 19th century has led to discharges of metals to the lakes situated downstream. The aim of the main study is to investigate the possibilities to reduce the environmental load on the surrounding ground and water caused by heavy metals from the mine. The present report is a part of the main study. The aim of the work is to investigate the geochemistry of the groundwater.

The tick-borne disease bovine anaplasmosis is primarily caused by Anaplasma marginale. A variety of wild animals act as reservoirs for A. marginale, but the understanding of their role in the epidemiology of A. marginale is yet poor. This cross-sectional study was conducted to establish if proximity of wildlife affect the prevalence of bovine anaplasmosis in cattle.

Tämnaren är en slättsjö i östra Svealand där ammunition går att finna i bottensedimenten. Ammunitionen härstammar från övningar som Flygvapnet hade över sjön under 1950- och 1960-talen. Sjön är mycket grund och näringsrik och befinner sig i ett område som fortfarande påverkas starkt av landhöjningen orsakad av den senaste inlandsisens tillbakadragande. Detta innebär att Tämnaren växer igen i rask takt och beräknas vara i princip borta om ungefär 600 år. Sjön har ett skyddsvärde dels genom sin rikedom på olika fågelarter som håller till i närområdet men också ett rekreationsvärde för människor i området runt sjön.

The interest for alternative forest regeneration methods increased significantly during the 1990´s after 50 years dominance of the clear-cutting system (Holgén & Hånell 2000). One reason for this was that clear-cutting was being more and more questioned by different envi-ronmental organizations and because the forest sector for economical reasons wanted to find cheaper ways to regenerate forests. In the beginning of the 1990´s two shelterwood experi-ments were established in a joint effort by Svenska Cellulosa Aktiebolaget (SCA) and the Dept of Silviculture, Swedish University of Agricultural Sciences (SLU). The experiments include various forms of cutting and shelterwood densities and represent productive spruce forests in central and north Sweden (Roggsjön in the province of Medelpad and Skikkis-jöberg in the province of Västerbotten, respectively ). The experiment next to Roggsjön has been reported earlier in three MSc theses, and is also the focus of this thesis.

This is a 20 credit Master thesis within the landscape architecture education at the Institute for Landscape Planning at the Swedish University of Agricultural Sciences at Alnarp. Norränga is situated on the fringe of the city of Lund, east of the existing district of Linero.The city planning office of Lund municipality has come up with a ?in-depth comprehensive plan? for the exploatation of the eastern area of Lund. The plan concerns an area of 1035 square kilometre which contains at least 1500 nya buildings, two schools, primaryschools, stores and bus station for local bus traffic and the new bus line - Lundalänken. The townplan is inspired from the historical Square block city with defined street system. The municipality has visions of what the green areas should consist of.

Titel: Redovisning av FoU-utgifter ? val av regelverk för mindre onoterade aktiebolagNivå: Kandidatuppsats i företagsekonomiFörfattare: Adam Bergman och Alexandra HellströmHandledare: Arne FagerströmBitr. Handledare: Annika LakeDatum: 2014-05-26Bakgrund: Under 2000-talet har svensk redovisning genomgått en stor förändring, och Bokföringsnämnden (BFN) har varit ett drivande organ i denna fråga. BFN beslutade 2004 att inleda ett projekt för att ändra inriktning på sitt normgivningsarbete, och projektet har de valt att kalla för kategoriseringsprojektet (eller förkortat, K-projektet). Mindre onoterade aktiebolag blir rekommenderade K2-regelverket, dock får inte utgifter för immateriella tillgångar aktiveras som en tillgång i balansräkningen inom detta regelverk.
