Stadsförnyelse i innerstadsnära läge. Utarbetning av en strukturplan för stadsdelen Rothenburgsort i Hamburg..

The Rya power plant in Borås produces district heating, district cooling and electricity. The plant is owned by Borås Energi och Miljö AB and is run by Dalkia Facility Management AB.In order to get the best heat exchange from the district hot water a pair of twin pumps and a turbine circuit pump are used as return pumps. Turbine circuit pumps are used to increase the pressure through the heat exchangers at the power plant. The pumps are in use when the flow is over 2 000 m3 h-1 and during the summer when re-cooling is used to improve the effectivens of the heat boilers.Since the pumps, that are parallel connected, rotating at a fixed rate per minute, the pressure is regulated with regulating valves. This report shows that during the 4,300 hours that the pumps where in use, energy corresponding to 590 MWh was wasted.

At the end of April 1986 reactor number 4 of the nuclear power plant at Chernobyl explod-ed and large amounts of radioactive particles were then released into the atmosphere due to both the explosion as well as the consecutive fire of the graphite core. A cloud of radioac-tivity was spread over the northern hemisphere, including Sweden, due to the prevailing wind directions. The radioactive particles were washed out from the cloud by rain and snowfall in some areas of Sweden and deposited on the ground. The deposited radionu-clides, primarily cesium and iodine isotopes, were later absorbed into the soil and taken up by the roots of the plants. Some of these radionuclides, like 137Cs, still persist in some of the terrestrial ecosystems at relatively high concentrations which lead to contamination of the meat of moose, roe deer and wild boar even today.The two municipalities Heby and Uppsala, in the eastern part of central Sweden, experi-enced a relatively large deposition of 137Cs which resulted in high levels of 137Cs in moose and other game.

Abstract: The aim of this study is to investigate the attitudes towards the labour movement?s strategies, goals and organisational issues in Swedish Miners? Union?s (Gruvindustriarbetareförbundet, hereafter Gruv) paper, Gruvarbetaren 1917-1925.The theoretical starting point is Engels? view on the class state. This perspective turns the question of socialism and the way to get there into an issue of working class power over the state. Another theoretical perspective is the partition of the labour movement into a trade-unionistic branch, seeing unions as financial organisations of interest, and a pro-state one, considering unions as political organisations.During the period investigated Gruvarbetaren was quite radical and advocated a firm class struggle strategy towards employers. Since these were considered unreliable, class struggle was seen as the only way to better the conditions for the working class.

Att arbeta med levande material i urban miljö blir alltmer till en utmaning för den gröna sektorn. Ett antal faktorer bidrar till att våra stadsträd för en tynande tillvaro eller dör i förtid. För att behålla våra städer gröna behöver vi dels en större mångfald av träd men även uppslag på nya och bättre anpassade arter. Syftet med detta arbete är att undersöka hur botaniska trädgårdar kan fungera som en källa till kunskap och erfarenhet för att utveckla trädanvändningen i urbana miljöer. För att kunna svara på frågan valde vi att undersöka tre botaniska trädgårdar i Sverige. Lunds botaniska, Göteborgs botaniska och Bergianska i Stockholm har ingått i studien.

Due to historically low prices for electricity in Sweden, many small-scale hydropowerplants were closed down. A small-scale power plant has more or less the samemaintenance costs as larger plants, but doesn?t generate as much income. Today?sincreasing price for electricity in combination with a desire for renewable energysources makes small-scale hydropower interesting again.

This study presents a survey of the seroprevalence of Toxoplasma gondii and Neospora spp. in equids in three municipalities in Pará, a Brazilian state with the Amazonian rainforest and the Amazon River as dominating features. Toxoplasma gondii and Neospora spp. are two closely related parasitic protozoans not separated as different genera until 1988. Neospora spp.

Politiska och ekonomiska svängningar samt geografiska förutsättningar präglar stadens fysiska planering samt dess uttryck och form. För Lund och Köpenhamns räkning har planeringsprocessen under drygt femtio år tillbaka skett utifrån ett antal plandokument, upprättade för att kontrollera stadens utveckling. Studier av dessa dokument visar hur städerna fysiskt brett ut sig i landskapet samt argumenteringen kring denna tillväxt. Under 50- och 60-talen bredde städerna ut sig för att kunna erbjuda fler och bättre bostäder under devisen ?välfärd åt alla?.

Begreppet biologisk mångfald har länge förknippats med bevarandefrågor som identifiering av skyddsvärda arter och upprättande av reservat. På senare tid har det dock allt oftare hörts tillsammans med begrepp som ekosystemtjänster, och då inte sällan i urbana sammanhang. Som blivande landskapsarkitekt känns det relevant att bredda förståelsen för hur man kan arbeta med ekologiska aspekter och därigenom biodiversitet i en tid som präglas av ett tätt och kompakt stadsbyggande. Detta kandidatarbete fokuserar därför på det utrymme den biologiska mångfalden kan tänkas ha inom urban planering, samt framförallt hur man mer konkret kan skapa stadsmiljöer som också hyser en rik biodiversitet. Två stadsutvecklingsprojekt där man arbetat med biologisk mångfald är Bo01 i Malmö och Norra Djurgårdsstaden i Stockholm. För att hantera frågan i ett planeringsskede har man i båda dessa fall använt en så kallad grönytefaktor, vilken syftar till att öka de ekologiska förutsättningarna genom ett poängsystem för gröna och blå kvaliteter. I Arbetets teoretiska del beskrivs den biologiska mångfaldens värden, i allmänhet och i en urban kontext, samt begreppets komplexitet och den problematik som kan uppstå kring otydliga definitioner. Därtill redogörs för planeringsverktyget grönytefaktor. En genomgång av Bo01-projektets arbete med ekologi och biodiversitet visar på höga ambitioner men varierat resultat.

District heating covers around 80 % of the heating demand in apartment buildings and 10 % in single-family homes in Sweden. In the year 2010 the total input of energy to the Swedish district heating grids was about 70 TWh, which corresponds to 11 % of the total energy input to the whole energy system in the country. Through the combined production of heat and power the CHP-plants often reaches an efficiency of 90 % from energy in the fuel to produced heat and power. In order to keep the efficiency high it is important for the owners of the plant to have good knowledge about the plants performance at different operation points. Strängnäs Energi AB initiated this diploma work together with FVB Sverige ab in order to come up with a program for short term planning of the production of heat and power at the company´s CHP-plant.The work consists of three main parts.

We came in contact with the project "Grönplan Danderyd" that aims to create a green structure plan for a municipality of Stockholm called Danderyds kommun. Our thesis is a part of this project and makes it's contribution through the gathering and systematization of the knowledge of the functions of an urban green structure. It also makes a contribution through suggesting how this knowledge can be applied during the construction of an urban green structure plan. We found that "Stadens parker och natur", published by the Swedish National board of Housing, Building and Planning, was a recurrent source of information in the green structure plans that we studied. We saw a need of complementary additions and updates to the rather old report and found literature that adds the developments of the last decade. First of all we have chosen to make themes based on the functions of a green structure that were presented by 'Stadens parker och natur'. The themes we suggest that a greenplanning document manage are: Recreation, Pedagogies and Heath, Biological Diversity, Green structure in the History of Building Cities, Cultural Identity, the Health of the City, Biological Technology in the Municipality and Use and the Users. We found good examples of how to handle these themes in documents that handle greenstructure planning from the municipalities of Göteborg, Strängnäs, Eskilstuna, Malmö, Lund, Västerås and Uppsala.

Syftet med arbetet är att undersöka fenomenet Urban Sprawl för att se om det går och få svar på varför Kungsbacka kommun ser ut som den gör idag. Kungsbacka har ett speciellt utseende med en väldigt liten centralort i förhållande till kommunens storlek. De flesta av invånarna i kommunen bor i utbredda villaområden utanför staden. Arbetet inleds med en teoridel som börjar med att beskriva Urban Sprawl i ett internationellt perspektiv för att till sist gå in på vad det har betytt för Sveriges och enskilda kommuners del. När man talar om Urban Sprawl förs ofta tankarna till USA med dess breda motorvägar, stora köpcentrum och utbredda städer.
