Samband mellan lågt tryck i dricksvattenledningar och magbesvär - En utredning av hur lågt tryck på dricksvattenledningsnätet vid lagning av läckor påverkar sjukligheten hos Göteborg Vattens abonnenter.
Two elementary schools are now being built in Gråbo (in the municipality of Lerum),Röselidsskolan and Ljungviksskolan, which are both designed with solar thermalcollectors for the schools domestic water heating. During the summer while thelargest amount of solar heat can be generated, the activity hence the domestic wateruse in the schools are heavily reduced. Both schools are connected to the local districtheating system which makes it possible to use the solar collectors to deliver heat tothe district heating.The purpose of this thesis is to evaluate the two systems mentioned above and todetermine which system is more suitable to apply on a school. The building whichconditions were used for this evaluation is Röselidsskolan.A solar heating plant of each system type was dimensioned from the expected andknown conditions of the building. The purpose with the dimensioning was to makethe solar plants replace the ordinary energy source as much as possible.
Translokation av större vattensalamander : -bevarandestrategi eller riskåtgärd?
This study evaluates the retention of nitrogen and phosphorus in four newly constructed wetlands in the municipality of Falkenberg, Sweden. The four wetlands have been selected because they have been specifically constructed with the aim to reduce nitrogen and phosphorus in farming areas. The process of selecting the specific wetlands has been done in collaboration with the county administration in Halland. Through field studies in collaboration with the landowners where the wetlands are sited, the areas that provide the wetlands with water were determined. The size of these drainage areas were determined in a GIS computer program. The type of land use within the drainage areas was also determined.
Riktlinjer för att trygga utrymningssäkerheten och tillgängliggöra information om utrymning och brandskyddet för Habiliteringscentrum Stockholm
Ett problem i offentlig miljö, som Habiliteringscenter Stockholm, är att enkelt och tillfredställande kunna informera de som vistas där hur de ska agera i händelse av brand. Denna information ska vara utformad så att alla som vistas där har möjlighet att begripa den. Detta är speciellt viktigt för offentliga miljöer där personer med funktionsnedsättning vistats. Metod som användes var att utföra en mindre litteraturstudie inom områdena befintlig brand/larm- och utrymningsrutiner, utvecklingstörning, kommunikationsteori och Habiliteringscenter Stockholm, för att få underlag till hur de tänkta rutinerna och informationsbroschyren skulle kunna se ut. Därefter arbetades det fram förslag som diskuterades och utvärderades av Rose-Marie Trillkott och Jan Gustafsson.
Beräkning av massbalanser för metaller i vatten samt miljöriskbedömning av Nerån vid Österbyverken i Östhammars kommun
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.

Leanuppgift för industriprogrammet
The government regulations for energy use in buildings will be tightened in the future. At the same time the interest in environmental classifications and certifications of buildings is increasing. This has meant a new situation for solar energy. The designs of solar heating systems are often based on experience and/or rules of thumb, rather than calculations and simulations. This thesis examines whether simulation tools, in this case Polysun, are useful in this work.
Ekologisk dagvattenhantering i Kungsträdgården
Det här är ett arbete om ekologisk dagvattenhantering i Stockholm. Området vi har valt att arbeta med är Kungsträdgården som ligger vid vattnet i centrala Stockholm. Arbetet är utfört dels som en skrivuppgift och dels som en gestaltning som behandlar de praktiska lösningarna i kombination med ett estetiskt värde. Gestaltningsförslaget ingår i en internationell tävling för studenter som har hållbart tänkande i fokus.
Utvärdering av Vissberga lakvattenbehandling
In connection with the admittance of the EC-directive (99/31/EC) in Swedish politic, through the constitution of waste depositing (2001:512) at year 2001, the rules about management the landfills and leachates tightened. At the landfill Vissberga in the municipality of Hallsberg, a leachate treatment plant was constructed just a year thereafter. This treatment plant consisted of an aerated pond with a following land treatment and a willow cultivation to replace the land treatment during the summer. In this case the parameters, which were estimated as the most important to reduce, were iron and nitrogen. The iron would react with the oxygen-rich water in the aerated pond and precipitate to ferric-hydroxide and than settle in a calm zone of the pond.
Mellan vattenspeglar och bebyggelse : En studie av innerstadens kajer i Stockholm
Denna uppsats behandlar innerstadens kajer i Stockholm. Syftet är att analysera hur innerstadens kajer fungerar som offentliga rum och hur de uppfattas av stadens invånare. Källmaterialet består till stor del av plandokument samt av intervjuer med både tjänstemän och stadens invånare. En fallstudie vid en av innerstadens kajer har genomförts för att på ett tydligare sätt förstå kajernas dynamik. Resultaten från uppsatsen visar att planeringen kring kajområdena är splittrad och uppdelad mellan många olika instanser. Denna uppdelning tycks ge kajerna dess fysiska och psykiska utseende som antingen uppskattas eller ogillas av stadens invånare.
Lyviken : -bedömning av dagvattenkvalitet
AbstractStormwater is defined as rain- and melted water. Ludvika kommun had little knowledgde about the stormwater that reaches a specific recipient Lyviken. Therefore they intended to do an research of the stormwater that leads down to Lyviken. The aim with this study was to assess the quality of the contents in the stormwater based on pH, conductivity, phosphorous, nitrogen, bacterias, oil and one sample that meassured the value of several methals. Since the population has increased for decades, the area of hard surfaces and asphalts areas also has increased. This can increase the pollutions that finally ends up in the recipient.

Förutsättningar för jökellopp vid Fox Glacier, Nya Zeeland
A great number of tourists visits each day the Fox Glacier in New Zealand and are subjected todangers such as jökulhlaups. This phenomena can occur suddenly and in a destructive way when abuilt up of water suddenly bursts and releases large amounts of water. This is well known to happen atthe near by Franz Josef Glacier which has similar settings to Fox Glacier, but sparse previous researchon the subject indicates different results of whether jökulhlaups are present or not by Fox Glacier. Thisthesis therefore aims to study the conditions for jökulhlaups at the glacier. This is done by remotesensing and field observations of the sandur in the Fox Glacier Valley, qualitative interviews andliterature studies with a comparison with Franz Josef Glacier.
Egenskapspriser på småhusmarknaden i Stockholm, Göteborg och Malmö - en hedonisk studie
I denna uppsats studeras betalningsviljan för småhusrelaterade egenskaper i Stockholm, Göteborg och Malmö för tidsperioden 1994-1996. Med en hedonisk prisekvation estimeras elasticiteter för ett antal småhusrelaterade egenskaper. Exempel på småhusrelaterade egenskaper är boyta, tomtyta, avstånd till kommunaltcentrum och förekomst av bastu. Studiens syfte är att jämföra om betalningsviljan för småhusrelaterade egenskaper skiljer sig mellan storstadsregionerna. Resultaten visar att betalningsviljan för småhusrelaterade egenskaper varierar mellan regionerna Stockholm, Göteborg och Malmö.
Energieffektiviserande åtgärder i samband med renovering av flerbostadshus
In Sweden, a big part of the energy use is used in the housing sector. Political goals and targets are set up which the housing sector needs to work towards. Apartment buildings are a major part of the housing sector in Sweden and therefore reduction of energy use in these kinds of buildings are key to lower the energy use in Sweden. But there are not only political incentives to reduce the energy use. Some energy?saving measures are directly profitable and should thus be performed.
Ombyggnation, från sågverkslokal till restaurang. antonio ziakoulis
Pharmaceuticals that are found in marine ecosystems are a threatening environmental concern, which is known to harm both animal and plant life. One of the reasons for this problem is that the waste water treatment techniques are not optimized to clear waste water from its pharmaceuticals contain. In this master thesis four Swedish treatment wetlands were studied, and their ability to reduce numerous pharmaceuticals in waste water. The four treatment wetlands that were studied were those in Oxelösund, Trosa, Nynäshamn and Eskilstuna. Two ecotoxicological tests and chemical analysis were used.
