Inventering och riskklassning av förorenade områden i Öna och Östnor :

This work consists of a survey and risk classification of eleven metal industries including foundries, finishers and engineering industries in two industrial areas in Mora. The study follows a method called MIFO (Method of Surveying Contaminated Sites) composed by the Swedish Environmental Protection Agency. In the method assessments of the degree of hazard posed by the pollutants, the level of pollution, the conditions of dispersal, sensitivity and the degree to which the area is worthy to protect are made for each contaminated site (object). The assessment classify the objects into four risk classes in which risk class 1 denotes a very large risk, 2 large risk, 3 moderate risk and risk class 4 little risk. The work of surveying using MIFO is divided into two phases.

Concentration and offtake of trace elements and macronutrients in Italian ryegrass (Lolium multiflorum Lam.) and spring barley (Hordeum vulgare L.) grown on soils amended with water treatment residual sludge

Aluminium sulphate (Al2(SO4)3) is usually added during the drinking water treatment processin order to precipitate organic and inorganic material, resulting in aluminium-based drinkingwater treatment residual sludge (WTR). Since 2003 Swedish law no longer permits WTR tobe deposited in lakes, and there is an interest to explore the possibility to utilize WTR as soilamendment. The aim of this study was to examine the effects of WTR application on cropgrowth and concentrations of macronutrients and trace elements (including micronutrients andpotential toxic elements). A greenhouse pot experiment was conducted with three soils; a clayloam rich in phosphorous (P), a loamy sand rich in P, and a silty loam with a low soil Pconcentration, and two crop species Italian ryegrass (Lolium multiflorum Lam. cv.

Effects of peat and wood shavings as bedding on the faecal microflora of horses

The main purpose of this study was to determine the impact of bedding material on the faecal microflora of horses. Another objective was to investigate the hygienic and physical qualities of the bedding materials used and how these may change in the course of the trial period. The bedding materials used were sphagnum peat and wood shavings. Six horses had each material as bedding for a three week period in a change?over experiment.

World Trade Center : ett arbete om hur myten påverkar oss

Det här arbetet fokuserar på den profana och religiösa människans omedvetna arketypiska arv som vi fått genom myterna, och vidare på hur detta påverkar oss i särskilda situationer. Som exempel har jag fördjupat mig i terroristattacken mot World Trade Center den 11 september 2001.I min första del beskriver jag myterna och olika mytkriterier, hur de är uppbyggda och vad de innehåller. Gemensamt för de olika myterna visar sig vara kampen mellan kaos och ordning och/eller det onda och goda, där harmoni måste råda på det jordiska planet såväl som på det gudomliga. I denna del tar jag också upp tidens betydelse och hur både den profana och religiösa tiden är av cyklisk natur där nyåret och återupprepning av högtider är av stor vikt för den psykologiska bearbetningen och personliga existensen.I min andra del beskriver jag staden New York och dess betydelse för innevånarna själva och omvärlden, som en stad med grandios arkitektur som själv talar om sig som en stad som symboliserar absolut frihet, välgång och tillväxt. Jag beskriver också tvillingtornen i World Trade Center som en axis mundi, ett mänskligt strävande åt det gudomliga, i världens navel, den absoluta mittpunkten.

Utvärdering av ett silotorksystem för spannmål utrustat med omrörare :

The aim of this study was to evaluate the stir drying method, for drying of grain during Swedish conditions. The evaluation was done during the harvest year 2004, on four farms with stir driers. The driers were evaluated for their energy consumption, design, stirring effectiveness and how much time the farmer has to spend on every tonne of grain. A comparison was also done with conventional Swedish high temperature driers. Totaly six batches of grain from stir driers were examined, mostly winter wheat, but also barley and wheat.

Vattenflödets betydelse för fångster av lekvandrande lax (Salmo salar) och öring (Salmo trutta) : En utvärdering av laxfällan vid vattenkraftverket i Forshaga

Many watersheds have lost stocks of migrating fish species because of the development of hydroelectric plants and other fragmenting barriers. The remaining stocks of migrating Atlantic salmon (Salmo salar) and brown trout (Salmo trutta) in River Klarälven, Sweden are five times smaller compared to one hundred years ago. A fish-trap at the hydroelectric plant in Forshaga has been vital for the continued existence of the stocks. This is the first hydroelectric plant of eight, blocking the way to the spawning grounds. Spawners are collected in the trap for both hatchery and transport by truck upstream and past seven more hydroelectric plants to the spawning grounds, where they are released for possible natural reproduction.

Beskrivning av systemfunktioner i kärnkraftverk med hjälp av objektorienterat modelleringsverktyg

In order to facilitate design and maintenance of such a large and complex site as a nuclear power plant, all system functions must be described in a stringent way. In the past, these descriptions consisted of text documents and logical diagrams, but today there are an increasing number of object-oriented programs available on the market which might be used for this purpose. This Master Thesis has made a closer study of one of these programs named Rational Rose. The principal of the program is to facilitate software design and development, not to create models of plants. However, using the program the same way as developing software, specifying actors then gradually extend the model with use cases, use cases diagrams etc, the same methods can be used when modelling plants.

Analys av fiskerättsförhållandena i Stockholms skärgård i relation till känsliga områden samt fysisk störning

This work is a GIS study of fishing rights distribution between different categories of ownersand properties in the Stockholm Archipelago. The purpose was to create basic data used toestablish fishing laws and restrictions within the Stockholm County.Stockholm?s archipelago consists of a unique environment and is the natural life andreproduction environment for ? of Sweden?s reproducing fish species. The increasingpressure from fishing, tourism and weekend population increases the need for an efficientfishing administration to prevent impoverishment and to ensure the biological diversity inSwedish fishing waters. There is an increasing need to review fishing administrationmethodologies, as well as studying the categories of ownership and properties located insensitive areas and areas influenced by physical disturbances in order to establish effectivelaws and restrictions.The Swedish fishing rights for an area are currently not connected to the ownership of theproperty to which it belongs.

Bagaren och biblioteket : Skolbibliotekets roll i undervisningen i karaktärsämnena på ett yrkesinriktat gymnasieprogram

In Swedish school library research, the role of the school library has seldom been studied in a subject-specific context. When it has been, the subject has usually been a theoretical subject such as Swedish or Social studies. The purpose of this master's thesis is to study what role or roles the school library can play in a different context, in the program-specific subjects at a trade oriented program in the Swedish upper secondary school, and to determine what factors affect the possibility for the school library to play a role in such a context. The Food Programme was selected as the specific program to be studied. In this program, the students learn a trade, in this case bakery, and the teaching in the program-specific subjects can be expected to be practical in nature.

Arboga möter miljöutmaningar och klimatförändringar

Municipalities in Sweden are responsible for physical planning by developing a general plan. This plan contains intended land and water use for the area. This study aims to investigate the level of integra­tion of environmental issues in the general plan of Arboga municipality and also how well adapted the municipality is for climate change. Further on, the study intends to examine the focus of the gen­eral plan and at what rate the national environmental strategies are implemented in the local physi­cal planning of Arboga municipality. Methods used for this study are interviews and reviewing of the general plan itself and other key documents.
