Östby waterworks in the community of Kramfors has since 2003 had problems of fast clogging of the slow sand filters. As the clogging appears more often, they must be cleaned more frequently which has made the drinking water preparation difficult. Wintertime it has sometimes been impossible to clean the filters which has led to their closing and this has influenced the water quality negatively.The waterworks is a surface waterworks which takes its raw water from the lake Sjöbysjön. The water is flocculated and filtered in a contact filter with the flocculent EKOFLOCK 91. Thereafter it is alkalinized before it reaches the outdoors placed slow sand filters.

This thesis presents the results from a osteological analysis and a GIS-study aimed to examinedifferences in the located animal bones in different areas of the excavation site of Ajvde.The osteological material came from five excavated square meters on the site and was comparedwith osteological results from other researchers from different areas to create overview and try tosee differences between the areas.The GIS-study took data from all animal bone material excavated on the site, a total of about 2300kilos, and presented them in maps of spatial distribution for each layer (pictures 4, 5, 6 & appendixpicture 1) to see if there were any clusters of activity and changes between the layers. The dating ofthe culture layer and the burial field (pictures 7 & 8) were presented in maps to see if they could becorrelated with what was seen with the animal bones. Pictures of different shorelines were alsopresented (picture 9) to compare with the results that were seen in the changes of animal bones fromdifferent layers.The results of the GIS-study have shown that the activity on the site have moved over time alongthe hight differences of the land. The earlier layers show activity only on the higher elevation butlater moves down, and in the upper layers activity have been all over the excavated area. Clusters ofanimal bones were seen in the so called ?black areas? of the sites (shown in picture 2) but also otherareas contained a lot of animal bones.The results of the osteological analysis have shown that there are differences in what species arefound in different areas.

Med beredning avses här den planering som görs för att möjliggöra och bestämma hur bearbetning skall utföras vid tillverkning av en enskild artikel.

This degree project concludes the Innovation and Design Engineering programme at Karlstad University. The project was carried out by David Brocker, Erik Hallberg and Andreas Hertzman during the spring of 2006 and corresponded to 15 weeks of work per student. Assigner was Martin Larsson at Arexor and instructor at Karlstad University was Monica Jakobsson.Arexor has a patent to a construction of an electrical skirting board with moveable wall sockets, called Electrical Track System. The lowest parts of the interior walls along the floor are today almost always covered by a conventional skirting board. Arexors patented product replaces that with the possibility to move and increase the number of wall sockets by choice along an electrical skirting board.

To investigate the possibilities for effective soil tillage, that could imply lower costs, lower negative environmental impact and in addition a meaningful occupation for foraging pigs, a field experiment was carried out in Gränna, Småland, during growing season 2006. The experiment contained two treatments that were repeated three times and were carried out on a couch grass-infected fallow on a light soil close to Sweden?s second largest lake, Vättern. Ploughing was one treatment and pig rooting followed by ploughing, was the other. The experiment was conducted according to the guidelines of organic growing and seedbed preparation was done the same way in the two treatments. The pigs, three groups of five half-year old Linderödssvin (an old Swedish breed), was encouraged to perform an even tillage by strip-grazing, i.e.

Meat and fish was the most important food for the Sami people in northern Scandinavia until the beginning of the 20th century. It is not so well known that the Sami people also used a lot of wild plants as food and medicine although that kind of food was relatively common among them until the end of the 19th century. The purpose of this master thesis has been to describe which plants the Sami people used in general and also which plants were the most commonly used, and when and how these plants were harvested. I also wanted to measure the quantities of Angelica archangelica and Rumex acestosa within traditional harvest sites. Furthermore I wanted to find out if the plant use differed among Sami groups geographically.

Background: Evaluation of lameness in horses is traditionally performed by a veterinarian who subjectively evaluates the movements of the horse. Accordingly, lameness diagnosis varies with the veterinarian and circumstances for which the horse is examined. Research within the area has long tried to establish an objective and standardized method for lamenessevaluation in horses. Several methods have been shown to be reliable and are used regularly within research, for example measurement of forces between the hoof and ground, and measurement of movements with high speed cameras or accelerometers. However these methods require considerable preparation, standardization, and expensive equipment as well as produce large amounts of data that are incomprehensible for the clinician.

Stump wood was used between 1850 and 1950 for production of tar and as firewood. In the 1950s the use decreased because of the introduction of the cheap fossil oil. In the 1970s stump wood became an interesting issue again as a raw material for the pulp industry. Stump lifting has today become a possible source for bioenergy. The objectives with this study were to investigate the productivity of stump lifting and stump extraction, and to analyse the economy.

Abstract This paper discusses protectionism of intellectual property rights in general and the conflict between large pharmaceutical companies? rights to patent and developing countries? rights to cheap generic preparation in particular. The essay focuses above all on HIV/AIDS medicine. The description tries to give an image of the different interests that collide and why they collide. The different actors are above all the pharmaceutical branch, including researchers, inventors and salesmen with their economic interest of revenue, and the population of the development countries and their pressed situation considering the great need of medicine.

This research focus on key groups; students with dyslexia, librarians and teachers, and interaction between these two professional groups regarding students with dyslexia. In searching for the exchange of knowledge and experience to meet dyslexic students needs, I have in this study turned the attention to librarians and their experiences with students with dyslexia.The purpose of the research has been through semi-structured qualitative interviews with four librarians, to explore and describe how they experience their work, in working with pupils with severe reading and writing problems, dyslexia, and interaction with teachers on this user group. The qualitative approach in the gathering of the empirical evidence is based on a desire to have an indepth and thoroughly understanding of the librarians experience.All informants in this study indicate that they see it as a natural part of their duty to keep themselves updated about dyslexia and what materials to suit the dyslexic user group. The informants have knowledge of dyslexia and have great knowledge and keep abreast on the latest technology of compensatory aids - alternative tools.The informants have primary a consulting and supply function for teachers and dyslexic students, where they are consulted on  suitable material in both fiction and facts in various disciplines. The informants highlights the importance of planning and preparation time to find suitable material, as audio books or easy read, so students who have a need for this also can be provided.

Syftet med arbetet är att ta reda på hur trummisar kan lösa mentala blockeringar i sitt musikutövande. I mitt arbete vill jag belysa vikten av expressivt spel och vikten av mentala aspekter i musikutövandet. Det är viktigt att arbeta med mentala "övningar" precis som det är viktigt med praktiska övningar. Musiker värmer ofta upp fysiskt inför en spelning men hur många värmer upp mentalt? Mina forskningsfrågor är: - Hur kan man påverka trumsetselevers musikaliska utveckling med hjälp av expressiva och mentala övningar? - Vilken roll spelar mentala övningar och förberedelser för professionella trummisar? Jag har intervjuat två etablerade trummisar och trumsetslärare, en vid musikhögskolan i Malmö och den andra en verksam trummis i Stockholm och före detta lärare på Musikhögskolan i Malmö.

The plants in the genus Elatine are characteristic for oligo and mesotrophic lakes. This study focuses on Elatine hexandra one of the four species in Sweden. It is stated as vulnerable by the National Environment Agency and a conservation plan with guidelines to preserve the plant in Sweden is under preparation. There have been a few previous studies investigating this plant in other countries but this is the first one for Sweden. The aim of this study was to investigate the distribution, growth and reproduction of E.

Detta examensarbete har utförts på SNA Europe i Bollnäs där en ny produktionscell för märkning, montering och paketering av handsågar planeras. Den främsta anledningen till uppkomsten av detta projekt är arbetsrelaterade problem orsakade av manuellt arbete vilket ger värk och besvär i skuldror, rygg och nacke hos operatörerna. Ett annan skäl är märkmaskinen, som med stigande antal stillestånd och ett växande behov av underhåll och reparationer, snart behöver bytas ut. Målet med arbetet var att ta fram ett förslag på en kostnadseffektiv halvautomatisk produktionscell med ett förbättrat arbetsmiljöförhållande jämfört med den nuvarande situationen. Projektet begränsas till att ta fram övergripande funktionslösningar.

The dog has often served as a model animal for humans in scientific studies. This is due to the fact that dogs are susceptible to a wide range of diseases which also affect humans. One example is cancer, a condition that affects dogs as well as owners. Neoplastic diseases account for 18-23 % of all deaths in dogs (Bonnet et al., 2005 and Jagielski et al., 2002). Mammary tumor, or tumor of the breast, is the most common tumor form in intact dogs and women (Im et al., 2013). Mammary tumors originate in the udder, and are classified according to their histological characteristics.
