This study examines how formal mathematics can be taught in the Swedish secondary school with its new curriculum for mathematics. The study examines what a teaching material in formal mathematics corresponding to the initial content of the course Mathematics 1c could look like, and whether formal mathematics can be taught to high school students.The survey was conducted with second year students from the science programme. The majority of these students studied the course Mathematics D. The students described themselves as not being motivated towards mathematics.The results show that the content of the curriculum can be presented with formal mathematics. This both in terms of requirements for content and students being able to comprehend this content.

Sexually transmitted diseases among youths is a growing problem. Generally, the knowledge about sexually transmitted diseases is relatively good, however, the risktaking among youths is great. The schools education regarding sex is often insufficient. The foundation for avoiding STD is knowledge. However, knowledge does not solve the attitude problem regarding the use of condoms.

The purpose of this bachelor thesis is to identify the relationship between color and semiotics and how a person?s opinon, regarding a game character?s different characteristics, can be affected by the use of various colors. Prior to this study people were asked, through an online survey, to write down words that they associated with different colors. The colors were then divided into four different groups depending on whether they had been associated with positive-strong words, positive-weak words, negative-strong words or negative-weak words. In order to further shed light on the effect of colors, the four palettes, consisting of the colors associated with the different words, were then used separately to give color to two characters: a man and a woman.

Good feeding practices are a basic aspect of good calf health. During the calf's first few months the calf is fed with purchased milk replacer or raw milk straight from the cow. On all farms, it will be a surplus of milk that may not be delivered to the dairy for various reasons. Milk that may not be supplied to the dairy includes colostrum and milk with unnormal properties, including milk from cows suffering from mastitis. This study investigated the possibility of improving the milk by pasteurization in order to secure its use as feed for calves and thereby obtain an improved calf health.

This study is about a guardian ad litem mission, role and relation to unaccompanied children. On the basis of qualitative interviews the study aims to understand the trustees? role and relation to unaccompanied children. We chose to interview nine trustees to achieve a better insight of the trustees roll. We analyzed the interviews and tried to gain a better knowledge about a guardian ad litem mission, role and relationship to unaccompanied children with role theory and concepts off pastoral power and trust.

This thesis examines the subject of change in public administration from an instrumental and an institutional structure perspective. The purpose of the thesis is to examine whether institutional structures affect the development of instrumental structures and if it in turn is possible to affect institutional structures by changing the instrumental structures. This case study is primarily based on a series of deep interviews with senior administrators and politicians within two new administrations in the municipality Karlstad, both which have been created by merging several smaller administrations, but also thorough analysis of several official document such as protocols from the municipal council meetings, Tja?nsterskrivelser and internal PMs.   The result of the analysis indicates that both institutional structures and the forming instrumental structures affect each other and  that their ability to affect each other depends on the dominance over the organization each structure has.  In my specific research case we can see that the institutional structure of the city-technical and housing administration has affected the outcome but the institutional structure of the cultural and tourism administration hasn?t.  While the structural change of the city-technical and housing administration hasn?t effected the institutional structure but the structural change of the cultural and tourism administration has affected the institutional structure of this specific administration..

This thesis examines the emissions costs of Swedish aviation and their degree of internalisation under current economic instruments. The results show that the degree of internalisation spans from practically zero for a long-haul flight to 6 per cent for a typical domestic flight, where the climate cost, including high-altitude impact, makes up the main part of the cost. To inform evaluation of the consequences of this underinternalisation, or attempts to correct for it using price instruments, the price and income elasticities of international leisure air travel from Sweden are estimated using household expenditure data and two different price measures. The resulting elasticities are very high ? 2.03 or 2.04 for the income elasticity and -2.53 or -1.88 for the price elasticity ? and should be interpreted cautiously due to data limitations, especially for the price elasticities.

ABSTRACTProblems with high turnover in nursing has escalated during the last years both nationally and internationally. according to previous research job satisfaction and quality of care was connected to specific features of the hospital work environement. It was also recommended by Coomber & Barriball (2007) to analyze job satisfaction at ward level with qualitative interviews to get a deeper and more extended insight in which specific features are of importance.The aim of this study was to investigate and describe the experiance of job satisfaction in relation to quality of care from nurses perspective. This study was carried out at an orthopaedic ward with primary nursing as organizational context of care.Two focus group interviews were conducted, they comprised nine nurses with at least two years experiance of primary nursing. A qualitative content analysis with inductive approach was used in order to develop more detailed insights of potential factors influencing work satisfaction at ward level.

Babies born prematurely are deprived of normal sensorimotor stimulation when placed in an artificial environment, the incubator. The aim of this project was to design a series of products that could promote the baby?s emotional and neurological development, and to facilitate parental bonding. The products designed in this project has a theoretical basis on the research available today on cognitive and emotional development in children born prematurely. They were developed in close cooperation with a group of parents and nurses in a neonatal intensive care unit.Presence is a product collection for developmental care, consisting of a mattress, a figure and a necklace. The mattress has vibration sensors that transfer the mother?s heart beat and speakers with recorded heartbeat and her voice.

Background: As a part of a national health control program, Statens VeterinärmedicinskaAnstalt performs diagnostics to screen flocks for certain pathogens causing high mortality,morbidity and/or serious economical losses. There are several viruses in the programincluding IBDV (infectious bursal disease virus), IBV (infectious bronchitis virus) and NDV(Newcastle disease virus). Method: 96 serum samples were collected from different poultryflocks in Sweden and analyzed by ELISA, which are currently used in the health controlprogram as well as by a commercial prototype of a multiplex immunoassay manufactured byLuminex Corp., which is currently under evaluation at the United States Department ofAgriculture USDA. This 4-plex assay detects antibodies for the three above-mentionedviruses as well as antibodies of avian reovirus. In the context of this study the ELISAs run inroutine diagnostics as well as a REO ELISA were used as the standard for comparison.Result: The antibody concentration in serum from vaccinated chickens was high while theantibody concentration level in serum from not vaccinated chickens was low.

Most of the city of Uppsala rests on postglacial clay with a varying content of sulphur. The sulphur occurs naturally in the clay in reduced form as sulphide and the clay is for that reason usually called ?sulphide clay?. Excavation during construction activities gives rise to large amounts of excavation material, of which the sulphide clay is a considerable part.When the clay is exposed to air and water, an oxidation of the sulphides occurs which may produce an acid leachate and the mobilisation of heavy metals bound in the clay or underlying material. The aim of the work has been to improve our understanding of the behaviour of sulphide clays and produce a basis for risk assessment in the future handling of excavation material with high sulphide content.

This study consists of a literature study and a survey in Tamil Nadu, India. The aim of the study was to get an understanding of horse feeding in tropical climates and what kind of feeding related problems that could occur because of the fodder. Information and data were collected from eight different stables and from Tamil Nadu University of Agriculture in the region of Tamil Nadu in March-April 2009. The horses in Tamil Nadu were given rice straw, unknown grass, Cynodon dactylon, lucerne, maize, Pennisetum glaucum x Pennisetum purpureum hybrid and Chloris gayana as roughage. As concentrates, the horses were given wheat bran, oats, barley, soybean meal, maize, carrots, coconut cake, peanut cake, horse gram and chick pea.

Eutrophication of lakes and streams are nowadays a well known environmental problem and implies an enrichment of the nutrients phosphorus (P) and nitrogen (N). Phosphorus is considered to be the most important component for the growth of aquatic plants and leads in too large quantities to an intensification of growth. Phosphate (PO4) is the fraction of phosphorus that can easiest be taken up by plants and thus have the greatest impact on eutrophication. Increased plant growth in lakes and unfavorable conditions for aquatic animals are two examples of negative consequences. A significant portion of the increased nutrient supply to nearby water can be derived to phosphate leaching from agricultural areas, where private sewers and agriculture is two main sources.

The supply of uninterruptible power can be applied to many areas wherecontinuous operation is highly prioritized.The application of uninterruptible power for motor operation is facilitatedusing a frequency converter. Direct current operated frequency converters canbe applied directly to the power reserve which removes the need for additionalpower-converting.Batteries have long constituted the power reserve but advancements inthe development of ultracapacitors have created a viable substitution. Ultra-capacitors have high energy storing capabilities and can be applied to highpower applications.Maxwell is a leading manufacturing company of ultracapacitors and pro-vide different modules with built-in solutions for voltage balancing. Unevenvoltages between series-connected capacitors is a phenomenon caused by vary-ing capacitance. A configuration containing Maxwell?s 56V module is createdand constitutes the power reserve in the simulations.The discharge simulation shows a significant current that could damagethe system.

The bean bruchid, Acanthoscelides obtectus is a major threat to bean production. In Ethiopia, where this study was performed, the damage by bruchids on stored beans has been reported to reach up to 38%. To use the isolates Beauveria bassiana and Metarhizium anisopliae in the management of A. obtectus can be an environmentally safe alternative for controlling the pest. In the present work the aim was to examine if the four chosen fungal isolates, B.
