AbstractThis study deals with preschool children's ideas about water in our body. Ten children with the age of four to five were interviewed individually, the interviews were qualitative. The children were also asked to draw their answers and answer questions about a picture that represented the excretory system. The results of my study show that children did not have any knowledge about the water being vital for us. Preschool children had no knowledge of why it is important to drink water.

Due to the fact that bottled water has negative impact on the environment,Elite Hotel hasdecided to stop serving bottled water in their restaurants. Since Swedish tap water is regarded tohave great quality,Elite Hotel wants to look at the possibilities to carbonate their own sparklingwater and serving it in fancy carafes. This Master of Science thesis is about constructing a costefficient water carbonator system that suits Elite Hotel?s need specification. This thesis alsocovers other water refinement criteria.The work has been divided into three parts.

The prevailing food and energy crisis of the world, due to the declining reserves of fossil energy and a never ending rise of consumption, forces us to look into new fields to supply our energy demand. The boom of bio energy is criticized, as food crops are used to provide biodiesel and ethanol and the volumes are ridiculously small to supply world demand. Algae are one of the world?s oldest life forms and exist in many different phyla, providing a great variety to choose from, for different purposes. Cultivating microalgae offer a way to produce energy at great volumes without competing with food production and at the same time the algae offer a way to use our expensive nutrients in a more efficient way, besides this the algae are carbon dioxide neutral since their carbon source can be supplied by the atmosphere and the additional energy required can be supplied by algal oil or other renewable sources.

Forest management plans have been sold to private forest owners by wood supplying companies for a long time. These plans are considered to be effi-cient tools to identify measures and wood volumes, and are simply a starting point for discussions between private forest owners and round wood pur-chasers. However, large variations are observed between different purchas-ers, in their usage of the plans. The purpose of this report is to identify to what extent a forest management plan can promote an increase in the amount of wood which a round wood purchaser can obtain and to find differences in the way of using the plans between different wood purchasers. Furthermore, the purpose is also to ana-lyse if varying owner structures can be underlie variations in the selling of forest management plans. Qualitative interviews with nine of Stora Enso?s round wood purchasers were performed.

This paper is intended to provide a picture of which associations water can wake in the human mind from the perspectives of garden history as well as from that of environmental psychology. I hope to paint a fairly broad picture of our perception of water that can serve as a basis for discussion and as a starting point for different forms of design work in landscape architecture. The historical perspective emphasizes the importance of water as a condition for the emergence of gardens and in a wider perspective the importance of water in early cultures. Also, I describe a picture of how water has been used throughout the history of gardens from early Egypt to the baroque era. The garden history analyzed from an art historical perspective gives a picture of human associations to water, and the history behind these associations is presented. As a compliment to the art history approach, I have chosen to highlight our associations with water from the perspectives of environmental psychology and evolutionary science.

The water company MittSverige Vatten (?MidSweden Water?) located in the Medelpad, Sweden was in need of a moreexclusive water carafe for restaurants and conference in the region. Current design solution was not able to cope with thedemand of a more exclusive setting and was not promoting the company in a good way. In the beginning of the projectit became clear thru an intense interview period that there was at least three directions for design solutions the companycould go for.? A carafe (exclusive settings)? A pitcher (conference and lunch servings)? A water dispenser type (serving of larger amounts of water during a certain brief periods of time.)It was decided to go for the exclusive one.Small pieces of rock from the last ice age turned out to be a vital component of the new design concept for the company..

Ronneby Miljö- och hälsoskyddskontor ville genom undersökningen få information om nitrathalter ienskilda dricksvattenbrunnar inom kommunen, med bakgrund av den nya miljökvalitetsnormen.Riktvärdet för nitrat är 50 mg/l. Halter som överstiger detta bör inte ges till barn under ett års ålder pågrund av risk för methemoglobinemi. Jämförelsen skulle ske mellan områden präglade av jordbrukrespektive skogsbruk, samt mellan grävda och borrade brunnar. Jämförelsen skulle även ske över tiden,mellan 1975-1990 till 2005. Urvalet av provtagningspunkter baserades på en sammanställning frånbefintligt arkiv samt efter en annons i dagspressen.

The private forest owners play a key role in the supply of round wood to the Swedish forest industry. Today it is a keen competition between forest companies about the wood from private forest owners. In order to get access to the wood from the private forestry you need to be an attractive collaboration partner, who can offer long-term collaboration, service at top-level, and acting for good prices to the forest owners. This work aims at analysing the situation on the market today. It gives Sveaskog purchase department a good view of the forest owners? opinion in general about the existing purchase activities. Forestry service level and timber prices are determining factors for a successful relationship between forest company and forest owner.

To guarantee protection of our drinking water, water catchment protections are established. These are divided into three different zones and in the first zone it is most likely that an activity, such as agriculture, will contaminate the water resource. Hence the activities are strongly regulated or banned. The EU communion is working towards a sustained water quality through several directives; Nitrate Directive, Waterframwork directives and Sustainable use of pesticide directive. The main purpose is to regulate the diffuse pollution from agriculture.This thesis is about how Denmark, Germany and France are working towards a sustainable agriculture within water protection areas.

The discharge from Lake Mälaren is regulated to keep the lake water level within limits set by a water decree. Despite this, in the year 2000 the lake water level rose above the upper limit. Studies conducted at the climate modeling unit Rossby Centre at the Swedish Meteorological and Hydrological Institute (SMHI) indicate that the inflow to the lake may increase in the future. A flood in the area will, among other things, strike infrastructure and residential districts.The aim of this study was to investigate the water levels of Lake Mälaren in future climates. In addition to this possible future expansion of the lake discharge though the sluice gates in order to keep water levels below limits set by the water decree and to prevent flooding of the shoreline were discussed.

Nanofiltration is a proper way of preparation of drinking water. The process has a lot in common with reverse osmosis where a semipermeable membrane is used to separate a pure water flow from the remaining water. A pilot plant was used to ensure that nanofiltration is a suitable technology for a specific waterworks station in Glemmingebro, Ystad. The purpose was also to find out if a pH-adjustment is needed for feed water in a possible full scale plant.  In this case nanofiltration is used mainly to remove sulphate and calcium since the raw water contains concentrations of these substances which exceed the limits for potable water. It is important to receive a high recovery (RC), otherwise the deliviery of water won?t be high enough.

This study aims to build a deeper understanding on how shareholder value is created in Private Equity investments, especially during the holding period. The study is a qualitative study of the buyout of the access security company Bewator AB made by the Swedish Private Equity firm EQT in 2002. The buyout became highly successful due to various reasons. The study draws the conclusion, contrary to popular belief, that Private Equity firms create value through taking a long term view on business developing rather than being short term value destroyers. Incentive alignment is another important factor..

Digital depth-to-water maps can be produced from a digital elevation model (DEM). Then GIS- based algorithms are used to calculate water flows and the depth-to-water index classes dry, fresh, moist and wet. The purpose of this study was to investigate the possibility to use depth- to-water maps for site adapted planting.The results showed that use of depth-to-water maps for site adapted planting, roughly halved the proportion of improperly planted surfaces from an average of 9 % to 4 %. The variation in the values of proper surface decreased and the result became more even.. In addition, more pine than spruce was incorrectly planted.

Uranium (U) is a naturally occurring component in bedrock and under the "right" conditions it can dissolve and move into the ground water. Since many people in Sweden depend on drilled wells as their main drinking water supply, they may be exposed to the uranium in the water. Radioactive radiation is not the major concern associated with naturally occurring uranium. It is rather the chemical properties of uranium that make it a potential danger to human health. Uranium is proven to have toxic effects with respect to the functioning of the kidneys.

The purpose of this master thesis was to study the water system for mechanically cleaned water at Skärblacka mill, in order to find and evaluate possibilities of using energy more efficiently. The thesis also includes an evaluation of the software tool ?Pumpanalys?Skärblacka mill produces pulp and paper. The large amount of water required is cleaned mechanically through filters and called mechanically cleaned water (MR0). The MR0 water is pumped out to the factory by four crude water pumps.
