What affects Hiv in South Africa's different provinces? This thesis examines if education, unemployment rate, GDP per capita, and the literacy rate has any relationship with the Hiv prevalence. This is analyzed using theory and data in the form of a simple microeconomic model and an econometric regression analysis based on cross sectional data of the provinces of South Africa. The regression analysis shows that unemployment rate and education have significant effects of the Hiv prevalence in South Africa. The microeconomic model in the thesis indicates that when education is higher, individuals are more aware that the probability of being infected by Hiv is higher when the Hiv prevalence is high.

The purpose of this thesis for Sapa Heat Transfer is to examine a furnace in which aluminium is pre-heated before hot rolling. The project is modeled in a computer environment in which the air flow in the furnace and the heat transfer to the aluminium solids are included. The computer environment and its governing equations, as well as boundary conditions and generalizations, are presented and explained.The simulations are based on two models. The first model has an asymmetric solid placement, which is how it looks in today's ovens. It is validated against collected data.

Nynas produces bitumen at two refineries in Sweden. The bitumen is shipped to seven depots along the swedish coast line, and from the depots special trucks handle the transportation to customers. Recently Nynas has transformed its supply chain and closed down a few depots. At the moment the company is considering a further reduction of the number of depots. In connection to these discussions an analyse of the companys distributionsystem and of possible changes is required.

The use of a bit in the mouth of a horse is being increasingly questioned with respect to its actual function, and is sometimes judged an obsolete instrument of control with potential to injure the horse. The objective of the research presented herein was twofold; firstly, to investigate the actual pressure load in the mouth of the horse with regard to oral health issues, and, secondly, to investigate whether this could be a viable method to objectively measure strength exerted by a rider/driver to the mouth of the horse especially with regard to training regimes. From the results, it is evident that these newly developed sensors have a future in equine research, although they are still under development. They can be useful both as a pedagogic teaching instrument, providing instructor and pupil with instantaneous, objective feedback on the contact between hand and mouth, as well as an aid in measuring pressure loads from our common bits. .

The aim of this study is to explore hiphop music as an aspect of youth socialization and the relationship between music creation and identity. The study is conducted through five semi- structured qualitative individual interviews. Our theoretical starting points are Putnam?s (2000) bridging and bonding social capital symbolic interactionism. We also have used a model of learning presented by Fornäs, Lindberg and Sernhedes (1989).

Due to excess precipitation that cause runoff, all soils in Sweden naturally leaches nitrogen.High leaching from arable land is an environmental problem when the runoff reacheswaters. In the international agreement, Baltic Sea Action Plan, the aim is to reduce therunoff of nutrients. Sweden has agreed to reduce its load of e.g. nitrogen to the Baltic Sea.One of the proposed measures is an increased use of site-specific N-fertilization, which hasbeen shown to increase nitrogen use efficiency and therefore also reduce the nitrogen runoff.Either yields are increased with the same total amount of nitrogen, or the total quantityof nitrogen is reduced with preserved yield levels, which is profitable for the farmers.The dynamics of nitrogen leaching differs between top dressing applications above orbelow the economical optimum. There is a consensus about a difference in the dynamics,but not about its magnitude.

This thesis aims to investigate if there are any differences in the value relevance of yearly earnings announcements before (2000-2004) and after (2005-2009) IFRS were implemented for listed companies in the European Union. To assess the value relevance of earnings, an earnings response coefficient (ERC) is estimated using a linear OLS-regression model. The regression model uses accounting earnings per share as the explaining variable, with the corresponding return starting from (but not including) the previous year's earnings announcement date, ending at (and including) the current earnings announcement date, as the dependent variable. This study finds that there is no statistically significant difference between the estimated ERCs for the two periods. Although no statistically significant difference is found, data shows that the R2-values, which measure the explanatory power of the regressions, are higher for the period before IFRS.

This Bachelor of Science thesis was carried out at Metso Panelboard AB, located in Sundsvall, Sweden. The work lasted for 10 weeks and began at the end of February 2007. Metso Panelboard is one of the leading suppliers of complete lines, single machines, engineering knowledge and after-market services to the fibreboard industries. The task involved building a 3D-model of a dryer cyclone in the CAD-program Pro/ENGINEER. A dryer cyclone is the part where the tree fibres are dried in the process of manufacturing fibreboards. Currently, it takes about two weeks to draw a dryer cyclone. By creating a 3D-model of it, which should have the functionality to be generated to different sizes, the goal is to decrease the drawing time to about 20 hours and to increase the quality of the work. This report includes the fundamental theories behind the manufacturing of fibreboards with focus on the dryer cyclone.

The starting point for this thesis has been the great process of change that Swedish municipalities now arefacing due to the political directive of offering full-time employment to all part-time employees. The aimof the research is to create a decision support model for Swedish municipalities, which simultaneouslyintroduce the offer of full-time employment and an internal personnel pool. The factors that mayinfluence the personnel?s choice of employment level and the quality of the outcome, thus the financial result,are we also aiming at explaining. The empirical observations were found through secondary data as well asobservations from the municipality of Göteborgs Stad.

SCA is the largest private owned forest owner in Sweden, with an ownership of 2 million hectares of productive forestland. To manage the planning of such large areas and to fit the traditional organization structure of a Swedish forest company, the planning approach is subdivided into three stages; strategic, tactical and operational. The strategic part, based on a statistic sample of stands, returns a harvest level estimate which should then be implemented at actual sites in the tactical part. This procedure can lead to incompatible solutions as the strategic solution is not necessarily possible to translate into actual sites in the tactical plan. The geographic aspect is important in tactical planning due to the large costs for moving equipment and maintenance of a large number of forest roads.

Study: Degree project in teacher education, Advanced level, 15 hpUniversity of SkövdeTitle: Religious belief in everyday life ? a study of the effects of a teachingmodel focusing on religious belief in everyday lifeNumber of pages:42Author: Johanna ClaessonTutor: Kennert OrleniusDate: Jan 2009 Keywords: Religious study, students´ understanding, students´ commitment,Buddhism  This paper presents the execution and the result of a project examining how a tutorial model (called the model of everyday religious practice) focusing on how Buddhism is expressed in the daily life of Buddhists believers, affects students understanding of and commitment in religious studies. In the project, Thai students have partaken by producing sex posters and a picture-show with the help of their own photographs and short texts. However, the picture-show was mainly produced by the author of this paper. These posters and the picture-show were brought to Sweden to figure as teaching material during a lesson in religious studies for students in year eight in a Swedish school.

Business Process Modelling Notation (BPMN) is a way to graphically draw a diagram of a business process. A BPMN diagram consists of several so-called flow objects. These are interconnected in the graph through sequence  flows. BPMN models are merely graphical representations of business process and there is a need to simulate these diagrams for different purposes. The simulation that now is available for BPMN is that the model is evaluated by checking if it is correct.

The Thesis purpose is in the context of system development validate the Scrum Methodology. Projects concerning information technology are difficult to manage and tend to fail in quality, time or costs. Scrum presents a new view of the system development. Better cooperation between customers and developers, continuous follow-up on daily basis and extensive communication in the development team are all characteristics of Scrum. Scrum is described as a new paradigm by its founders but has been criticized by experts of system development too.

The voltage regulation in Fortum Distributions medium voltage network in Stockholm does not work satisfactory. This results in too high distribution voltages with many customer complaints as a consequence. The reason is the model responsible for compensating for voltage drops in the distribution network. Despite several adjustments Fortum has not been able to find the source of the high voltages and has therefore appointed an investigation in the form of a thesis work.The aim of this investigation is to locate the error and to produce a proposal regarding the solution of this error using the existing system, common industrial knowledge, state of the art research and the option to use voltage readings from the different substations.The conclusion of this master thesis is that the largest contribution to the high voltage levels is made by the large compensation for distribution loses. Furthermore an additional error in the model has been found.
