Kadmium i skånska vattendrag : en metodstudie i föroreningsmodellering
Modelling of pollutants is commonly used in research and at departments working with environmental issues. The need to use large amounts of data when modelling creates the opportunity for more generalised models with lower data demands. Aggregating functions into coarser elements is a sort of generalisation of actual features in nature.A development of a method and a modelling tool called ?KadmiumKalkylatorn? has been performed to model cadmium pollution in rivers in Skåne, Sweden. The water runoff has been multiplied with cadmium standard concentrations based on membership in landuse classes.

Mannen, myten... Stereotypen? : En kvalitativ innehållsanalys av hur manliga stereotyper konstrueras i tidningen Cafés reklamannonser
The discussion about gender and ideals shown in mass media is a subject of great importance for the society in general. Media is playing an essential part when it comes to establish standards and values and we are constantly exposed to all types of impressions, whether we are aware or not. It is therefore of great importance that we understand how stereotypes are built and to gain a deep knowledge that would enrich the area of Media and Communication Studies.The aim and focus of this study was to analyze how male stereotypes is communicated in print advertising and how visual means of expressions helps to construct the masculinities shown. From a semiotic analysis of seven print adverts appearing in the Swedish lifestyle Magazine Café were we able to gain a thorough understanding about how male stereotypes are communicated and built.The result showed that different kinds of stereotypes are in fact used but it is still a hegemonic masculinity that is predominating. Traditional male characteristics are still in use but we were able to see strong indications of effemination, sexualizing and objectifying.

Temperatursprickor i ung betong : Utvärdering av projektering och utförande av åtgärder, samt utveckling av dimensioneringsmetod för kylsystem
The report contains three parts. The first part is a summary and overall presentation of thermalcracks and preventing measures against such cracks. This is a theoretical part where theinterested designer can get acquainted with various alternatives, be guided to more detailedliterature, and receive some practical information regarding the design of the respectivemeasures.The second part deals with calculation of the risk for thermal cracks and design of water coolingas a limiting measure. Two complementary methods are reviewed for efficient calculation:?the handbook method CraX1(by Lulea University of Technology) is used for quickverification?finite differential analysis in the calculationtool ConTeSt Pro for more precise projectingHere is also presented a development of existing standards through design of the cooling systemby means of the Bernoulli equation.
Dagsländor eller bestående värden? En studie om urval av musikfonogram på folkbibliotek.
This paper discusses normativity in selecting musical phonograms in public libraries. The purpose is to gain an increased understanding of music activity in public libraries. To do this I have interviewed five music librarians about their visions, ideals and goals with their work. The questions discussed concern ambitions with the music activity and how to keep up to date with current record releases. For the theoretical frame I use two kinds of material.
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.
Ger läroplanen vägledning? : En fallstudie i hur personal på förskolan tolkar och resonerar kring förskolans uppdrag
I intend to examine how teachers interpret the purpose of preschools and the national curriculum and how they handle any problems rising due to the fact that the curriculum is just an instructional document and freely interpreted. Personnel working within the school system have different opinions on how to maintain a functional educational activity. How do they interpret the national curriculum and why? Are there any similarities or differences between different teacher?s views and is it possible to approach this in a constructive way? Is it really possible that personnel working at Swedish preschools are unaware of their purpose or is there another explanation?In this study I have worked according to the qualitative method and have been conducting interviews with the possibility to open follow-up questions with room for interpretation. A total of six people on four different preschools have been interviewed and their answers have been analyzed as a whole.The result from these six interviews shows that there are both differences and similarities in their interpretations of the purpose of the Swedish preschool.
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 biogas residues on respiration and denitrification in arable soil : evaluation of methods, microbial activity and agronomic implications
Agricultural soils constitute the base in human food production and soil content of organic matter and plant nutrients together with soil microbial activity are all important parameters for high crop yield of good quality. These parameters are dependant on proper fertilization.Anaerobic digestion of organic wastes for biogas production generates a liquid residue called biogas residue (BR). It contains organic material and plant nutrients which makes ita potential fertilizer for arable cropping. However, it also contains heavy metals and toxic organic compounds and it is therefore in need of evaluation before usage.Microbial tests were performed aiming to evaluate the agronomic traits of four different BR and to find a viable procedure for evaluating slurry fertilizers. Two experiments where soil respiration and soil potential denitrification activity (PDA) was measured at fertilizer addition were performed.

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.
Wildlife Detection Network
Traffic accidents where wild animals are involved represents between 60 and 80 percent of all reported accidents, depending on location in Sweden. In a country like Sweden, with a lot of forest, there is always risk of a collision with a wild animal. Imagine if you, as a road user, had the possibility to receive warnings when the risk of an accident according to statistics is extra high.Wildlife Detection Network is a wildlife warning system with an information service, which makes the whole concept unique. When an animal is approaching the road, it is registered by sensors, and warning lights along the road are lit to inform drivers of the potential danger. In conclusion, this is a direct warning to all drivers on the road where the system is placed.When an animal is registered by the sensors, information containing time, date, weather circumstances and coordinates are sent to a database.
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.
Den tryckta pressens framtid i en digital miljö : Med Nya Wermlands-Tidningen som exempel
The research in question examines whether a newspaper benefits from its activity on the Internet and if so - how. Today, the morning press is relatively stable, but tendencies show that there?s a decrease amongst regular readers. The extension of this may jeopardize the position of the morning newspapers in the market and several newspapers choose to publish their content on the Internet. An Internet activity is foremost about keeping the position in the market, not to make an economical profit, and to compete at the same terms with free newspapers and news sites.
