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.

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.

Many organizations today work in projects, a method of organizing work to provide a clearer focus on goals and more control of every aspect of the assignment. A project is, simply put, a plan to achieve a specific result. In turn, project management means to use various tools and methods to facilitate and streamline the effort towards achieving the goal with the project.Risk management is the activity that refers to finding, identifying and quantify different types of risks and take appropriate action towards reducing or eliminating these risks to the extent possible. With increased use of projects as a method of working the demands for managing risks better become stronger. The question that this thesis tried to answer was: ?What kind of risks does the IT industry think are linked to their projects and in what way does these companies manage these risks??Among the project leaders interviewed, the authors could see a great variation in lines of thought and values regarding the importance of risk management and how risk management should be handled.

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.

Storm water is rain and melted snow that runs off, primarily from impervious surfaces.Future storm Water management is facing the challenges of increased precipitation, asclimate changes, and increased areas of impervious surfaces due to the expansion anddensification of the cities. Impervious surfaces reduce the potential for water to infiltratein the ground leading to increased surface runoff and higher peak discharge.The runoff coefficient is closely related to the percentage of impervious surfaces andrepresents the maximum percentage of a catchment that can contribute to runoff. In thisstudy, the objective was to evaluate the weighted runoff coefficient for three differenturban types; apartment buildings, townhouses and residential areas and a comparisonbetween today and the 1970`s was made.The runoff coefficient was determined by manual mapping of the different surface typesin each area based on data in the form of orthophotos and aerial photographs. The surfacetypes that were mapped were asphalt, permeable areas, tiles, sand/gravel and roof.Tiles and sand/gravel were the most difficult surface types to map. In order to see towhat extent these categories influenced the weighted runoff coefficient a sensitivityanalysis was carried out and the runoff coefficient based on surface type was changed indifferent scenarios.The results of the sensitivity analysis showed that the surface types tiles and sand/gravelhad little impact on the weighted runoff coefficient which in mainly due to the fact thatthe percentage of these surfaces types of the total area is small.The result of the study showed that the largest change in the runoff coefficient occurredin residential areas where the increase in the percentage of impervious surfaces causedby new roofs in the form of porches and garages and from paved or tiled driveways.

Trough the contact with the HR (Human Resources) department of home care management in Halmstad municipality, emerged from the management a wish for a documentation for what should be included in leadership at middle management level in the future. People in middle management positions have a large impact on the operation staff and are also in charge of the individual corporate performance and its success. As we have previously been active in the management of multiple role configurations, including middle-management positions, we have some prior understanding of the complexity of this position. The study was conducted with the aim to investigate different aspects of what leadership for middle managers in home care management in Halmstad municipality may mean to them. With the help of different theories and models various aspects were analyzed due to the impact of leadership.Due to the studies purpose and questions, two focus groups was conducted and interviews with respondents from both the lower and superior positions in home care management in Halmstad municipality was done.

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.

There are regulations in sweden that require organizations to manage occupational,  health and safetey (OH&S) issues in a systematic way. The contents of the management system vary depending of the activity of the specific organisation. An accurate management system is crucial in order to assure that rules and regulations are fullfilled. The OHSAS 18001 standard covering OH&S management is intended to provide organizations with the elements of an efficient OH&S management system. The work with this thesis was done at Swemat AB in Härnösand wich is a mechanical industry. In the thesis, the requirements of the OHSAS standard are compared with the current management system.

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.

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.

Design management är ett arbetssätt som har börjat tillämpas av allt fler företag de senaste åren, men det kan fortfarande vara svårt att förstå betydelsen av design management. I uppsatsen undersöks det vilken betydelse en design managers kompetens och position har för samarbetet mellan det designköpande företaget och en designkonsult under ett designinköp. Genom ett flertal intervjuer, utifrån både design managers och designkonsulters perspektiv, undersöks det hur samarbetet fungerar mellan dessa parter. En analys av intervjumaterial med hjälp av en teoretisk referensram bestående av design management-teori, design som en integrerad process och beslutsrollsteori har lett fram till ett antal slutsatser om design management. Några av slutsatserna är att design management, enligt teorierna, som arbetssätt inte är så vanligt och att det finns en viss samarbetsbrist enligt de intervjuade designkonsulterna, som i viss mån underlättas om design managern har kunskap om vad design innebär..
