Assuandammens påverkan på Nilen, Egypten
Regulation of rivers by dams and reservoirs is a good example where anthropogenic impact could be considerable both in the local environment, but also has major implications upstream and downstream. This study was accomplished as a literature study of the river Nile, which is extremely important for water supply. The purpose of this study was to investigate the consequences of the construction of the Aswan High Dam, to obtain a consistent flow for water supply, irrigation and power generation in Egypt. Since Egypt has a very hot and dry climate large amounts of water in reservoir is lost to the Nubian aquifer system and by evaporation. The consequences from constructing the dam are considerable.
Demokrati och Statskapacitet i Latinamerika
This thesis, drawing from several empirical investigations, reaches the conclusion that there seems to be a positive correlation between the level of democracy and the level of state capacity in Latin American countries. This correlation is explained by a hypothesis derived from Rational Choice theory. With some important caveats, this conclusion is then applied to the discussion about democracy as a form of government. Within democracy, the thesis also offers an insight into different electoral systems and its possible implications, mostly on a theoretical level. The thesis only exists in swedish as of yet..
Rätt ordning på liv och lära? : En undersökning av stiftens tillsynsansvar inom Svenska kyrkan utifrån domkapitlens disciplinåtgärder mot präster och diakoner år 2006-2009
The study has shown that retailers in the mid-price segment differentiate their brand through developing a strong company identity around the brand. The personality involves store atmosphere, merchandise and advertising. Larger companies have chosen to lay the responsibility on management level, which facilitates on store level. By controlling the strategies on a central level the company can make sure that the stores are steered in the direction that the company wants them to be steered in, and also that they follow the positioning-concept. The company can also devote its efforts to working with its core value, which is service.
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.
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.

attraktrivitet och regionplanering : Hur ska osby kunna ha en positiv ekonomisk tillväxt och befolkningsutveckling i region skåne?
AbstractAttractiveness may be defined by a variety of factors but you should see it in the public planning as it is to have a positive population growth and economic growth, through working with communications, service, housing, to name a few. This is done primarily through direct projects both within the municipality and through various partnerships between local and regional level. The progress we have seen in recent years has gone more towards a clear shell level, particularly a regional level where these have had a much greater freedom with clear geographical boundaries in between each other. Within these regions there are also clear regional groupings that have common interests and competing between each other. In my thesis, we have been distinguished including three levels of scale levels.
Att beskriva upplevelsen av stadens rum :
The city is complex, multi-faceted and fascinating. The same can be said about the rooms
of the city. The experience of the rooms of the city can be described in as many ways as
there are individuals. The question concerned in this essay is How can you describe the
rooms of the city as a phenomenon and how can you describe the experience of these rooms
in general?
The concepts city and room are widely understood and neither of them has a description
that can be used in all situations.
Spelets regler Europeisering genom interaktion mellan Europeiska unionen och klubbfotboll
This thesis examines the interaction between European football and the European Union and if it can generate Europeanization. By using theories of Johan P Olsen and Claudo M Radaelli a theoretical framework was constructed in which Europeanization is seen as an interaction between the European level and the domestic level. The Europeanization is regarded as a two way process with elements of top-down and bottom-up pressures. The study focus on the changes and the actors in the Europeanization process and how the European Union as a top-level and European football as a bottom-level influence each other to European changes. The theoretical framework is used to analyze the Bosman case and the Cotonou agreement's implementation in a Swedish football context.
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.
Handla! En diskursanalys av konsumtionssamtalet i Norrköping under 90-talet
In Shop! Daniel Svensson is studying the Public Consume Conversation during the 90´s. Focus is based on two local papers in the Swedish town Norrköping and the Public Media Conversation, which these two represent. What kind of discourses has been dominating this conversation, that is the most important question in Shop! To answer this, Daniel Svensson uses the Critical Discourse Analysis, by Norman Fairclough, as an analytic tool. This method provides him with the possibility to connect the micro level of text with the macro level of the society. But this demands theories of the contemporary society at a macro level.

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.
Återvinning av näringsämnen från hushållsspillvatten med omvänd osmos
Hammarby Sjöstad is a new district in Stockholm with high environmental standard. Stockholm Water Company evaluates a local wastewater treatment plant with cutting edge technology. The first step is an experimental treatment plant (Sjöstadsverket) with four parallel lines of treatment, each with a capacity to treat wastewater from 150 persons. Within the membrane technology subproject the possibility of using reverse osmosis (usually called RO) to regain nutrients is examined.Reverse osmosis separates the incoming water in a clean permeate and a concentrate that, as the name indicates, is a more concentrated version of the incoming water. Using this method in wastewater treatment, a solution high in nutrients can be obtained without the use of chemical precipitation agent and with no production of sludge.
