On a request from the water sewage plant Gryaab in Gothenburg a power quality survey was performed. The voltages and currents have continuously been sampled in the incoming 10 kV substation HSP01 from April-August 2008. Power quality measurements were also performed in Gryaabs other 10 kV substation HSP04 fed from HSP01 and at the terminals of the induction motor IN_PU4040 of 1.3 MW which controls one of the four large inflow pumps to the plant. The reason for the latter measurement was due to registered negative transients each time the motor was connected to the grid. The cause of the transients could be explained by the coupling in the substation, the ageing of the motor which could result in damage of the bearings or resonance in the motor circuit which amplifies high frequency harmonics.

The corn plant came to Europe with Christopher Columbus in the 14th century and have ever since bin cropped here, but corn haven?t bin very common in Scandinavia until recently. The mainly use for this crop silage but even corn for grain is cropped in Europe. Corn for grain is a common part of feed in beef and chicken farming. In Sweden corn for grain is pretty rare but almost 1000 hectares are used for this crop, Lantmännen Sverige is the biggest buyer of corn at the moment.

When establishing a groundwater protection area it is of great interest to be able to estimate the transit time of the groundwater from different places of the aquifer to the withdrawal well. These estimates can be uncertain due to heterogeneities in the aquifer. As a part of the work to develop methods for a more certain delineation of protection areas, a tracer test was performed in an esker located 25 kilometres NW of the town Uppsala.The purpose of this master thesis was to perform, describe and evaluate the tracer test. Travel times from the tracer test should then enable comparison against stochastic simulated travel times of the groundwater in the area.Three dyes (rhodamine WT, uranine and naphtionate) and a salt (NaBr) were used in the tracer test. The tracers were injected in four different wells located 25 meters from a pumping well.

The Swedish forest have about 100 000 km of watercourses and it?s an important structure in Swedish landscapes and catchments. In some of the watercourses lives spieces like the freshwater pearl mussel (Margaritifera margaritifera) and brown trout (Salmo trutta) which both are sensitive for inteference from the forestry. The new EU water framework directive has a goal that all surface water will have high or good ecological- and good chemical status at latest by the 22nd December of 2015. The study has been made in the catchment of Håltjärnsbäcken and it is from a national perspective one of the most valuable streams in Sweden and which also have been included in a LIFE-project. The catchment is situated within the Eco-park of Malingsbo-Kloten and managed by Sveaskog AB.

Angelica archangelica (Garden angelica) is the only Medicinal and Aromatic Plant (MAP) with a Nordic origin. The plant can reach up to three meters when cultivated. Angelica archangelica is used as flavouring in additives, honey, beverage base, essential oils, fol-klore medicine and as ornamental for decorative purposes. Commercial cultivation is mainly focused on root production. Production countries are Poland, Netherland, France, Belgium, Switzerland, and former Czechoslovakia with an overall yearly world production of 1000 kg of essential oils.

In the last few years the environment becomes more watchful, even for us farmers. All agricultural enterprises that exceed 200 animal units must be tested according to regulation of environment. A farm business with 200 animal units and more is classed ?environmentally hazardous activities? and has to make an environmental impact assessment for the business you have today, and the activity after expansion. Before you can construct a building and expand the numbers of animals is a lot of applications to make. I have in this project restricted me to establish a environmental impact assessment and a consultation foundation. To make a environmental impact assessment is the big part of the application. The environmental impact assessment take a lot of time and you need skills for all the rules in the environmental code to be abele to make an environmental impact assessment approved. The environment codes purposes (1 kap 1 § Miljöbalken) is to rule the laws. The purpose of the environment code is to promote sustainable development which will assure a healthy and sound environment for present and future generations. Definitions of a ?environmentally hazardous activities? 9 kap 1§ Miljöbalken) shall mean the discharges of wastewater, solid matter or gas from land, buildings or structures onto land or into water areas or ground water.

This master thesis has been a pilot study preceding a forthcoming project of a larger scale with the long term objective to separate the direct effect of added nitrogen on soil processes from indirect effects via trees. The aim of this study has been to investigate the allocation of nitrogen following direct injection of liquid solutions into the xylem of 40 year old Norway spruce. The field site is located at Flakaliden (64°07?N, 19°27?E), approximately 60 km northwest of Umeå, Sweden. A total of 18 trees were selected for treatment, equally divided between three treatments, potassium nitrate, glutamine and water (control).

Tumble dryers and drying cabinets have to a large extent replaced the traditional way of drying clothes outdoors. They are faster, more convenient, require less space and can be operated regardless of weather conditions. This replacement has significantly increased residential energy consumption, due to the fact that tumbles dryers consume large amounts of electrical energy. In the USA 9 % of the households electric energy is consumed when drying clothes. Over 4 million tumble dryers are sold in Europe each year and 20 % of the residential electricity consumption in Sweden is used drying and washing clothes.

My purpose with this study was to find out if it is possible to buy a farm today for a person who want to start a farm but has very little own capital. In old study?s they have come to the conclusion that you will need at least 20 % own capital to succeed to management the farm. But in the last year the cost for arable land approxley has increased with 30 % in Sweden and the crops have doubled in price. So it would be interesting to see if the banks have a new vision on the need of the own capital when you buy a farm. I have chosen two different farms who was for sale in Östergötland, one dairy farm and the other farm was a plant farm.

The object with the study of this literature was to describe differente programs of care and patients and relatives experience and opinion about the caring for patients with Anorexia Nervosa. The method the author used was a descriptive literature study based on imperial studies. The studies were based on 15 scientific articles within the chosen field. The results shows that these patients hade special needs to be seen and heard as individuals, involved in their own treatment, and have good contact with the caring staff. The study also shows which methods were mostly appreciated involving nurses, patients and relatives.
