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.

Industrialization of construction is by some considered to be a solution to the building industry's problems about the lack of quality, high production costs, low productivity and poor environmental adaptation. Meanwhile, industrialized construction partly earned a bad reputation after the million housing program. As large-scale projects where promoted during this period, it worked very well to use the technique of construction elements. In the mid seventies though, criticism arose which claimed that the aesthetic qualities had been deprived in the corporates effort to make housing production as efficient as possible.Tyréns, Derome and CBBT (centre for building and housing in wood) cooperates in a development project to develop a building system for 4-8-storey buildings, consisting of three platforms: a technology platform, an IT platform and a processing platform. The technology platform consists of flexible, industrially built flat modules of wood and from this platform the subsystem stairwells, is broken out.

Bakgrund. En gyllene standard för att bestämma noggrannheten för intraorala scannrar existerar inte. Intraorala scannrars prestanda som ges av olika leverantörer är inte fullt jämförbara. Det finns ett behov att standardisera och ta fram oberoende försöksupplägg för att kunna jämföra intraorala scannrar. Mål. Målet med studien var att beskriva och utvärdera en ny metod för att bestämma noggrannheten av intraorala scannrar genom ett standardiserat in vitro testförsök och att använda metoden för att beräkna noggrannheten på en kommersiell intraoral scanner. Material och metod.

When beef calves are weaned abruptly at 5 to 6 months of age this triggers a strong stress reaction, since the animals have not yet untied the bonds to their mothers or stopped suckling. This is displayed as extensive vocalization and restlessness. Attempts to diminish the negative effects of weaning on sucking calves have been showing varying results. The study presented here emanates from the observation that when calves are weaned without human interference they are only prevented from suckling, but are still allowed to have social contacts with their mothers. The hypothesis was that calves weaned in two steps would be calmer, gain more weight, and be healthier than animals that were abruptly weaned. To investigate this, 15 calves where weaned in two stages (Group 2), by Fitting the calves with nose tags that prevented them from suckling during 5 days prior to the separation of the cows and calves.

This master?s thesis is a remote sensing study of an area-based method used to detect forest in need of thinning by use of laser data and field samples. Only pine-dominated forest has been included in the study and height limits were set to match empirical restrictions. The study area was in the municipality of Älvsbyn (Latitude 65° 40´ N, Longitude 21° 00´ E), in northern Sweden.The Swedish authority Lantmäteriet is currently laser scanning most parts of Sweden, providing new opportunities and applications. The primary aim of the national laser scanning is to create a new elevation model, useful in consequence analysis of climate changes.

This thesis project focuses on the need for better tools for analyzing competition for forest fuels in Sweden, in particular how policy measures may influence the market and involved actors in different regions of Sweden. Raw materials from the forest have for long constituted important inputs in the Swedish forest industry. Today some of these raw materials are increasingly used as inputs also in bioenergy production, largely driven by bioenergy promoting policies, and there are signs of increased competition for forest fuels which may have various and uncertain effects on the industries in question. The thesis project explores the possibilities to adapt previously used forest sector equilibrium models into a new model suitable for analysis of Swedish forest fuel markets, called the Swedish Forest Sector Trade Model (SFSTM). The approach takes into account regional differences in supply and demand for 23 types of products produced and/or used by eight types of producers, plus consumers, in five different regions (four Swedish and one international).

Uppsala Universitet Sophie DicksenMedie- och kommunikationsvetenskap C-uppsatsAbstractTitle: Communication of gender through design -A study of shapes and colors of perfumebottles and of the fonts on their labels.(Genuskommunikation genom design -En studie av form, färg och typsnitt på parfymflaskor)Number of pages: 39 (82 including enclosures)Author: Sophie DicksenTutor: Mats LindCourse: Media- and Communication Studies CPeriod: Autumn 2006University: Division of Media and Communication, Department of information Science,Uppsala UniversityPurpose/Aim: To study whether gender is communicated through design, and if so is the case, the aim is also to see by which aspects gender is communicated.Material/Method: 40 perfumebottles, 20 for women and 20 for men has been studied, and attributes such as their shapes, colors as well as the fonts on their labels has been analyzed in search of gender differences. An art director has also been interwiewed to receive information about genderdesign from a practical wiew.Main results: There is no difference out of a gender perspective between the colors on the bottles in aspect of lightness but colors on ladieperfumes are generally more saturated and they are also more often located among yellow, orange and red shades on the color chart while perfumesbottles for men tend to consist of yellow, green and blue colors in more unsaturated versions. The results of the study of shapes showes that there are more cubes among the male perfumes than there are in the group of womensperfumes. Concidering the study of fonts does results prove that fonts on labels of male perfumes mostly belong to the most common group of fontfamilies. This compared toperfumes for ladies where the the fonts varied between the two current fontgroups of the study, and therefore are bort rare and common.

This master thesis is a study of anaerobic thread lockers and is done in cooperation withÖhlins Racing AB, which is a Swedish manufacturer of vehicle suspensions.The suspension in vehicles is constantly exposed to high vibration levels and a suspensionunit has several screw- and cylindrical joints. As an extra safety precaution so that thecomponents in the suspension doesn?t fall apart when using the vehicle, an anaerobicthreadlocker is added in these joints. The handling of these threadlockers is not totallyharmless and could lead to allergic reactions, and therefore there are Swedish laws to limit theuse of these. However, new types of anaerobic threadlockers have recently been launched onthe marked that are not considered under this law.

The need for roundwood transport capacity vary throughout the year. The need during a period is influenced mainly by the volume transported the period, the number of days during which transport can be carried out, seasonal variations in road conditions and the weight of the roundwood, and the origin of the wood (private forest owners/ forest companies). The need for transport capacity generally increase during the winter and in spring, after thawing. Lack of logging trucks combined with a lack of drivers for these trucks make it hard to hire extra help during periods of increased transport capacity needs. It is also very expensive to keep logging trucks for use only during these periods. In this thesis, two new concepts based on the partial transport by truck tractors have been examined, to find out the possibility for increased performance and flexibility.

AbstractWe decided to explore former school pupils? experiences of not conforming to the norm. Earlier studies have focused on the children as ?the problem?.  We see this as worrying, especially since there is very little research focusing on the pupils? own experiences. The children?s own perspective needs to be brought to the fore.

Bakgrunden till rapporten var att det företag som medverkat i studien ville utveckla ett grundmönster för damkappor. Syftet med arbetet blev därför att utarbeta ett grundmönster med två ärmtyper som graderas mellan storlek 32-50, samt konstruera en kappmodell från samma grund. Utöver detta skulle även detaljkonstruktioner och specifikationer utformas. Frågeställningarna som styrde arbetet kretsade därför kring hur man på bästa sätt tar fram detta.All konstruktion utfördes i Lectra´s Modaris. För att ta fram grundmönstret jämfördes två arbetssätt för att sedan välja en av de grunder som konstruerats.

Aggression between laboratory mice is a common problem and can result in welfare issues such as mice hurting or killing each other and also stress. Swedish laws and regulations clearly states that mice must be housed with a companion due to their natural social structure. Many studies have investigated the effect off enrichment, group size, cage size and other potential changes in in their environment on the occurrence of aggression. Even with these changes aggression can exist and therefore a new solution was tested in this paper. The proposed solution was to house an intact mouse with a castrated one and thus fulfill laws and regulations while still maintaining the physiology of one of the mice for the purpose of medical experiments.

Bakgrunden till denna rapport är att det sportvarumärke jag samarbetat med ville utveckla en modell av längdskidåkningsjacka som fanns i deras sortiment. Undersökningen gällde att identifiera förbättringspunkter på en dam- och herrvariant av denna jacka. Avsikten var att bevara plaggens design och genom förändringar i mönstrens konstruktion förbättra passform och rörelsefrihet, och därigenom plaggets funktion. Genom att konstruera, sy toiler och prova av dessa på provmodeller, har rörelsefrihet och passform kunnat utvärderas. Resultatet visade att viktiga punkter var raglanärmens konstruktion, böjningen av ärmen, kragens form, ärmhålsdjup och placering av skärlinjer.

The vegetable production in Sweden is concentrated to the very southern parts of the country. This is also were the major wholesalers are located. In recent years, there has been an extreme focus on price on the food market. As there are only a few big wholesalers and also very few food retail chains, these have a great impact on the producers. The pressure from prominent vegetable-producing countries, providing low price products, such as the Netherlands and Spain is strong.
