We are heading towards a huge switch of how energy is produced with fossil fuels being replaced by renewable energy sources. It is not difficult to replace the energy you use in the house and there is no need for futuristic technology. There are already many established products on the market such as high efficiency vacuum solar collectors, heat pumps & small wind power stations that can supply the energy being used in a house. The company Sol & Energiteknik SE AB in Huskvarna has many different products which can reduce the need for an outside energy distributor. An average house in Sweden uses 15 000 kWh for heating, 5000 kWh for tap water and 5000 kWh for electricity.

Nearly 74 percent of the Swedish population invests in funds and the options are therefore various. The Swedish private investors can choose between active and passively managed funds. Fund managers, who seek to generate higher returns than the market, manage active managed funds. Unlike the active managed funds, passively managed funds do not require any active investment decisions.Fama?s (1970) efficient market theory reflects all available information in the stock price, therefore it is not possible to predict how the stock price changes.

Recent years have been very turbulent for most private equity firms. Especially the financial meltdown in global economy has affected the industry, but also the public pressure has made private equity houses change their control strategies towards more conventional methods used in public companies. This thesis aims to put light on the control methods used in listed private equity houses which use a buyout strategy. The paper describes how the control methods change over the different phases the asset experience and how different value generating strategies use altered control methods. Using Merchant's (2003) framework for management control systems and Berg and Gottschalg's (2004) research on value generating strategies in buyouts the thesis shows that action controls as designing instructions for the board and a business plan, together with goal alignment is the commonly used control strategy directly after the acquisition.

Water hardness indicates the concentration of calcium and magnesium ions in water. Water with high concentrations of these ions is described as hard water and water with low concentrations is described as soft water. Water that is too hard or too soft can lead to technical and economical problems. In collaboration with Midvatten AB, groundwater hardness in the Badelunda esker between Leksand and Avesta has been mapped, and an attempt has been made to explain the variations. For this purpose, different GIS programs, such as ArcView, ArcInfo, IDIRISI, and one geochemical modelling program, PHREEQC, has been used.

In this study potential health risks for employees in connection with handling of bottom ash and bottom ash water at a Municipal Waste Incineration (MWI) plant have been investigated. Air surrounding the bottom ash and the bottom ash water has been examined. MWI is one of the primary ways to manage solid household waste, and bottom ash is the main solid residue produced by the incineration process. Bottom ash constitutes about 15-20% of the original waste. The bottom ash is extinguished in a water bath (bottom ash water).The study was carried out in a MWI plant in Karlstad, Sweden.

AbstractThe purpose of this study is to find out how pupils give expression of a water cycle model and if the model causes any misunderstanding. Two problems constitute the starting point for this investigation. The first question is: how do the pupils explain the water cycle with the help of the jar model (can of glass). The other question is: can the children see any similarities between the can of glass and our earth. Qualitative semi structured interviews with seven pupils in the ages of 8-9 have been used to show the pupils? own thoughts and how they express them.

This report will show the energy usage of Hotel Princess in Sandviken, Sweden. When the hotel changed owner an examination of the hotels heating, ventilation and sanitary systems were done. The report showed flaws in the ventilation system, and is why the new owner wanted a closer look at the energy use of the hotel. The original building was built in the 1930s and two major extensions have been built, one in the 1950s and the most recent in the 1980s. An assumption made is that the building parts were built to the restrictions during the time. Activities on the hotel include sleep over, conference, night club, massage and swimming in the hotels pool section.

In Sweden there are 1894 small-scale hydropower plants in operation, which together generate 4.3 TWh of electricity per year according to Swedish hydropower compound (SVKF, 2011). This corresponds to the annual consumption of about 860,000 Swedish households (based on an annual consumption of 5000 kWh). In the mid-1950s there were around 4000 small-scale hydropower plants in operation in Sweden before cheap fossil fuels and uranium competed with them, in the current situation only 1,894 of these are in use. If slumbering small hydropower plants once again would be taken into use and some new ones are built, we would be able to extract about 7 TWh of renewable electricity from these annually in Sweden, representing about 1.4 million households.The thesis intends to calculate and construct a hydroelectric power plant at the existing dam in Olofsfors and give suggestions on how the power station should run during the time that fish migration is greatest in Leduån.The turbine and generator to the station in Leduån at Olofsfors is designed by the height of the fall and the water flow through the dam. The turbine selected for the station is a CK-1000RM turbine with a 4-pole 250 kW generator from Cargo & power turbine Sweden AB, which is expected to deliver 1.2 GWh per year.

Turbiditet är ett mått på partikelinnehåll i dricksvatten samt ett sätt att beskriva vattenkvaliteten. Vattentäkten i Gäddvik, Luleå kommun, har periodvis hög turbiditet. Syftet med examensarbetet är att utreda orsaker till turbiditet i dricksvatten, från Gäddviks vattentäkt till konsumenter i Luleå kommun. Målet är att ge svar på vilken typ av partiklar som orsakar turbiditen. Analyser utfördes före och efter filtrering av dricksvatten.

An increasing global population and a worldwide growing urbanization has raised the questionabout the future food security in cities all over the world. Peak-oil limits the access to cheap fossilfuels which threatens the global food-supply chain. This has resulted in a larger awareness anddiscussion related to urban agriculture. Growing crops and keeping animals within the city-borderscould be one way of creating a more robust and sustainable food supply for city dwellers. However,to enable an expansion of the urban agriculture many theorists argue that policies and institutionalstructures that supports and promotes city farming have to be developed.

The population growth in Europe and with that in Sweden was enormous under 18th century. The results became housing shortage in large part of Europe. Tight residency/ inhabited, poverty and emigration were series of social questions in Sweden. Private house (egnahem) as in the beginning was an idea from England and Germany became a political measure and the answer at those miserable social circumstances in Sweden. The purpose with the private house (egnahem) was to help those new people moved in to towns with place to live and counteract movers to towns and emigration. With the governmental loan and land availability that some municipalities and wealthy people contributed with, could people get a place to live with the small garden. The city garden (trädgårdstaden) with their future idealistic idea/utopia, English gardens, ideas with roots in the old-fashioned gardens (allmogeträdgårdar) and lots of books and periodicals were the source of inspirations. From these the private house gardens (egnahemsträdgårdar) were born. Object for my study is my and my family?s own house in Limhamn, south west of Malmö which was built in 1912 under private house gardens era. The garden and the building have still trace and element from the time of private house. My suggestion is inspired by the private home style with a new thinking design that answers to daily need and the busy life style; a rather easy to maintain for green environment. A more relaxing and peaceful garden with simple design, a garden despite that it is surrounded by neighbours and streets invites in harmony and dreams..

Mosquitoes are found in extremely large numbers in the lower parts of the River Dalälven. In the year 2000 the mosquito nuisance was especially high, resulting in foundation of the Biological mosquito control project. Since 2001 mosquito larvae are controlled by using a biological pesticide BTI (Bacillus thuringiensis ssp israelensis). The mosquito fauna in the area is dominated by flood water mosquitoes, a group of mosquitoes that are very aggressive and form new generations of mosquitoes during every single flooding event during the summer. To be able to efficiently control the mosquitoes it is essential to know the extension and locality of the flooding.

Vomb meadows is an area well knows for its rich bird life. During the 19:thcentury until mid 20:th century, the meadows were flooded annually in order toincrease the hay yield. The river Klingavälsån situated along the west side of themeadows, used to be a shallow river, meandering across the landscape. In the1940?s the river was straightened and made deeper.

Recent years there has been discussed how the critical situation in the housing market threatens the Stockholm region's growth. The thesis objective is to examine whether there is a scientific link between the lack of housing supply and growth. The thesis also intends to identify solutions for increased housing construction, for instance by examining the conditions for a greater regional perspective and influence on the region's housing supply. The thesis empirical study is based on semi-structured interviews with representatives from the Government, municipalities and the housing industry.In Sweden, research on the relationship between housing shortages and growth has not been conducted to that extent it can be said to exist scientific evidence regarding the growth threat. However, in Britain and the U.S, empirical studies show that a lack of housing supply has hindered growth through negative impact on countries' gross domestic product.
