Magnetic resonance imaging (MRI) has the potential to be used for the diagnosis and study of osteoarthrosis in the equine tarsal region. In the development of new diagnostic MRI techniques cadaver specimens are often used. To allow the use of cadaver legs for these types of studies it is important to know the effect of time after death on the MRI image. Since the relaxation times are temperature dependent, it is interesting to examine whether the time after death and the temperature of the cadaver may play a role in the image appearance and quality. The radio pulse sequences that show the different types of tissues are also important to know when pathological evaluation with MRI is used.

This master thesis comprises analysis and dimensioning of a keyed joint between a generator axis and a hub with aid from the FEM-software ANSYS Workbench 13.0.The generator axis is a part of a hydroelectric power station that generates electricity with a reactions turbine, a Kaplan turbine. The existing keyway consists of one parallel key with the width 90 mm and height 45 mm. Due to a planned increase of the power of the generated power with 32 % a design study was needed to see if the keyed joint would be suitable for the extra force. Because of the fact that the axis diameter is bigger than the standards covers/recommends a the keyway had to be re-dimensioned. In an earlier assignment from Skellefteå Kraft AB to Sweco Energuide the keyway was planned to be properly dimensioned, but no final solution was approved.During this master thesis a number of different numerical tests were made.

This master thesis is made in co-operation with the Department of Forest Management and Products at the Swedish University of Agriculture in Uppsala and the Forestry Association in Stockholm. The purpose of the Master thesis was to describe how pre-schools in Sweden use forests and green areas, and to understand how different factors can affect the use of the nature. The purpose of the interviews was to create a picture of attitudes and routines of the pre-schools, in the matter of visiting the nature. The thesis is built on interviews where fifteen pre-schools in five large cities around Sweden participated. Among these pre-schools, five of them worked with special focus on nature, while the other ten did not have any particular focus connected to their activity.

The Swedish pulp and paper industry meets higher demand for energy efficiencyi mprovements with increasing energy prices and changes in the Swedish renewable energy certificate system. One action of energy efficiency improvement is by using secondary heat, that otherwise would have been treated as waste heat, for use in a system with lower temperature demands. The aim of this Master´s thesis is to identify possible secondary heat sources in a typical Swedish pulp and paper mill and to investigate what economic benefits the secondary heat will provide when being used for pre heating of wood chips to a kraft digester.The Master´s thesis focuses on three secondary heat sources; dry warm air, warm water and moisture saturated warm air located inside the pulp or paper mill. Two types of kraft digesters are simulated within this study, a typical Scandinavian digester and a modern twin vessel steam phase digester.Due to quality aspects and low temperature level drying is the drying technology with dry warm air rejected. Using warm water in direct contact with wood chips increases the quantity of water to the evaporation plant and thus reduced pulp or paper production and is therefore also rejected.

A quadrocopter isa helicopter with four rotors placed in across formation. The quadrocopter cannavigate autonomous between different GPSpositionsthat are updated during flighttrough Xbee-modules. All levels fromsources code, design of the electronics todevelopment of the chassis was performedduring the project.

The purpose of this master's thesis is to examine children's communication and interaction during story time at the public library. The aim is also to examine how to develop the story time ? in terms of participation and equality ? at a specific library.Action research was used as a research strategy and participant observation, log, tutoring and interviews as methods to collect data. Since action research is done on the basis of practice, a significant collaboration with the librarian and the participant children is taking place within this study.Research from the fields of Library and Information Science, Education and Childhood Sociology form the interdisciplinary research area to which this study links. The theoretical framework consists of theory and concepts from the Socio-cultural Perspective, Poststrucuralist Feminism and Childhood Sociology.

The aim with this master's thesis is to describe the work process with the graduation film Player, by a composers perspective and given conditions. It provides a detailed insight into how the work was done from the script stage to the end result, scene by scene reflecting about both the musical performance and the collaboration between the director and me as a composer. The work was done during the spring term of 2012 at the Royal College of Music in Stockholm and Stockholm Academy of Dramatic Arts..

This master thesis was carried out at ELFA, one of the largest catalogue distributors of electronics in northern Europe. ELFA offers a wide selection of products such as measuring instruments, fuses and screwdrivers. The master thesis handles the possibilities of an increase in the internal flow of products. The background to this problem is ELFA?s acquisition of two new companies, which brought the product range in the warehouse from 55 000 to 80 000 products.

A large part of the interactions between horse and rider during horseback riding takes place through the reins and the bit and devices for measuring the tension on the reins, rein tension meters, has fairly recently been developed. To safeguard the welfare of the ridden horse riders need to be aware of the rein tension they apply and actively work to decrease it. Furthermore, there is a need to develop the study of rein tension through new techniques and refined analysis procedures. A good-quality rein tension meter should be small in size, sensitive, durable and as accurate for light rein tension as for strong forces. Rein tension meters used in research on horse and rider interaction commonly depend on strain gauge technique for generating rein tension data.

Background: Climate changes are a growing concern all over the world today. In June year 2006 the European Union accepted a new strategy for the Unions work against a sustainable development. The concept of taking consideration to all the aspects of an organisations/a company's activity is something that have been in focus during later years. Social and ethical aspects are in focus and questions regarding these aspects are more commonly included in the companies yearly reporting. A sustainability report is characterised by that it takes into account not only environmental aspects, like ordinary environmental reports, but also social and ethical aspects of a company's activity with it's surroundings.

The construction industry has not undergone the same logistical development as the manufacturing industry; this, in combination with increased material price, leads to the fact that the construction industry must be improved. This master thesis is a part of the research cooperation Brains & Bricks goal of reducing production costs for the construction sector by 25 percent. Brains & Bricks is a cooperation between Linköping University, Peab and Katrineholms municipality. The master thesis aims to identify improvements in the flow of material, the Supply chain operation reference, SCOR, model has been used and the work has been carried out on one of Peab?s construction sites. At present the business is characterized by bad communication both between the construction site and the office as well as between the construction site and suppliers.

The empirical data used for this master thesis, consists of eight manuals with the main purpose to help students evaluate information resources found on the web or Internet. The purpose is to elucidate the discourses and investigate those textual characteristics, which figure in the investigated manuals. The method used is a discursive and linguistic approach, with a power/knowledge discussion applied to the results. The analysis identifies, among other things, the production and consumption of the investigated texts, and that the manuals function as a reflection of the relationship between the participants in the situation, the sociocultural practice of the institution and its identity..

In this master's thesis the problem of determining the uncertainty for an estimator of an unknown parameter is considered. The case we study is the estimation of gravity using a reversible pendulum. This involves the estimation of the point where two regression lines intersect. The estimated gravity is a function the coordinates of this point. One way to determine the uncertainty of this estimator is to use bootstrap methods.

H-1 parvovirus (H-1PV) är ett autonomt onkolytiskt parvovirus. Dess naturliga värddjur är råtta, men det kan även infektera andra vertebrater. H-1PV kan tas upp av alla celler men är endast skadligt för prolifererande celler i neonatala djur och tumöromvandlade celler. Vid infektion av tumörceller kan tumörsupprimerande mekanismer genereras. Dessa kan vara direkt cytotoxiska och celldödande, eller indirekta genom att aktivera viralt eller tumörspecifikt immunsvar.
