The purpose of this study is to describe melanotic tumours and the pathogenesis of these tumours. The focus of this study is on differences between benign and malignant tumours as well as the prognosis one may expect when diagnosing this disease. The mechanisms responsible for the occurrences of the tumours are not yet fully understood. It is believed that factors such as chronic trauma, infections, medications and hormones affect the cell mechanisms in some way. Determinants of the malignancy of the tumour are not completely known.

The development of productivity in the construction industry has long been at a steady state compared to the manufacturing industry. Studies have shown that, amongst other things, waste on construction sites can reach up to one third of the total production cost. This has been observed from different aspects, and change is forthcoming.This thesis aims to provide a foundation for an increased productivity at production sites of building bridges. It is primarily based on a field study at Skanska, at a bridge construction site near Grängesberg. Via continuous interviews with the whole production crew, construction workers and management, information on interference and possibilities of improvement at the work site has been documented.

Barley is one of the most important cereals cultivated in the Nordic countries. Climate change brings warmer and moisture climate which favors fungal diseases. In the cropland barley can be seriously infested with hard fungus attack. Since it is important that the yield bears a high quality it is of great importance to find varieties more resistant to attacks.Pathogenesis-related (PR) proteins are stress proteins induced in the plant in response to infection and abiotic stress (van Loon, 1997). PRs are shown to have antimicrobial activity differing between bacteria, fungi and oomycetes (Tandrup Poulsen, 2001).

Rapid urbanization causes competition over land use between green area preservation and urban development in cities and greatly affects ecosystems as well as human well-being. This conflict is significant all around the world as many cities are now replacing existing green areas with new developments. The area around Dag Hammarskjöld's väg in Uppsala is currently experiencing the same conflict, as the need that the city has for new housing represents a threat for the many valuable green areas that are in the site. The purpose of this project was to understand how the need of urban development and the preservation of green areas could be balanced. This understanding would thereafter be used to make a design proposal for the area around Dag Hammarskjöld's väg.

Title: What women want ? a study about young men?s self-presentation on the on-line dating site Spray Date.Authors: Anna Tuvehagen & Josefin HultTutor: Lena Widding-HedinPurpose: Our main purpose was to identify implicit norms and ideals for masculinity in young men?s advertisements on the on-line dating site Spray Date.Questions: How do the men present themselves on Spray Date and what do they accentuate in their advertisements? What kind of relationship do the men hope to establish and what qualities and attribute do they look for in women? Are there any notable differences and similarities regarding our findings of ideals and the ones in previous research?Method: In order to answer our questions we chose 100 advertisements made by men in the age 18 to 25. To analyse the advertisements we used a qualitative content analysis, however we have some quantitative elements.Main results: The men in our study are searching for love on Spray Date and usually describe themselves as nice, cheerful, decent guys with good sense of humour. Although, spare-time interests and activities are what the men mainly focus on. Their interests are broad and all sorts of combinations occur why it is difficult to place the men in categories.

WordPress är ett av världens mest populära Content Management System. Eftersom det har en hög popularitet drar det till sig uppmärksamhet från personer och grupper som av olika anledningar vill utnyttja säkerhetsbrister på webbsidor. Syftet med denna uppsats är att testa säkerheten i olika tillägg till WordPress som externa utvecklare skapat eftersom dessa inte genomgår någon obligatorisk säkerhetskontroll. Insamlingen av data skedde via ett utförande av statiska tester på några utvalda tillägg. Denna teknik grundar sig i en granskning och analys av dokument i form av text, modeller eller kod.

The aim with the literature study is to inform about the risks that exists in large dairy farms(with focus on mastitis and hoof health) and to inform about the milk industry in Sweden.Personal comments from two study visits (Nötcenter Viken and Vadsbo Mjölk AB) arelinked together with the literature and forms into a discussion regarding sustainableagriculture versus the milk cow's welfare.The profitability for Sweden's milk farmers have decreased because of the decreased milkprice and current inflation. This leads to an increase in herdsize in order to make a profit.The milk cow herds in Sweden becomes fewer year by year and the herdsize increases. Theincreased herdsize can cause a decrease in the time the farmer spends per animal. This canaffect early disease detection and prolong the animals suffering.Swedish Board of Agriculture published (2008) statistics showing that today's milk cow ismedicated primarily because of two reasons; mastitis or hoof problems. Mastitis is thereason to two thirds of all treatments that are carried out.

This study was the first part of a larger project investigating a new surveillance method for Echinococcus multilocularis. In this study we examined livers from wild boar (Sus scrofa), looking for lesions caused by E. multilocularis. E. multilocularis is a small tapeworm which has an indirect life cycle.

Extensive planting of the tree species lodgepole pine (Pinus contorta var. latifolia) during the 1970s and 80s has resulted in large areas now being available for commercial thinning. However, the varying quality of the stands creates a problem. The purpose of this study was to investigate, at the Torsby district of the Stora Enso forest company, how well the present computer records of the stands correspond to reality and determine which stands are, from a qualitative perspective, suited for timber production. Finding variables that indicate better stands would give Stora Enso the possibility of selecting qualitative stands which are more profitable to thin. The study included 32 stands containing at least 70 % Pinus contorta.

This survey was made during the summer of 2004 and the spring of 2005, on commission from the National Board of Forestry. The aim of this report was to investigate how often Norway spruce (Picea abies L. Karst), is planted on poor Scotch pine (Pinus Silvestries) sites and if it affects the yield of Norway spruce? In order to investigate this, data from 29 stands witch had a lower site index than T24 was collected. The investigated stands were situated in the southern-eastern Sweden. In 20 plots in each stand, the highest tree, age, number of seedlings, site index and tree species per stand were measured.

This master thesis encompasses an inventory of the older industrial community of Gimo. Investigations of the contamination situation for each industrial area were done. A risk classification according to the Swedish Environmental Protection Agency?s ?Method of Surveying Contaminated Sites?, phase one, followed. The risk classification was done on areas of Iron Work, a rockwool industry and a landfill. Gimo have had iron manufacturing from 1615 until 1945. Gimo have had two blast-furnaces and two smithies periodically.

Feed intake in dairy cows is regulated by a variety of factors influencing hunger and satiety. One of the regulation systems includes the short chain fatty acids produced during feed degradation in the rumen. Starch can be digested either in the rumen where short chain fatty acids are produced or in the small intestine where glucose is the end product. Since glucose does not have the same effect on satiety that short chain fatty acids have, the site of starch digestion might be an important factor that affects feed intake and milk production. The aim of this study was to investigate the effects of site of starch digestion on feeding behaviour (feed intake, consumption time, and eating frequency) and milk production. Because feeding behaviour is closely connected to the cows? environment, the study also included observations of behaviour. Three different feed rations were compared.

Examensarbetet har genomförts i samarbete med innovationsföretaget ProboNova Medical Innovations AB. ProboNova jobbar främst med konceptframtagning av medicintekniska produkter. ProboNova tar sedan en Provisional Patent Application på konceptet och licenserar ut det till ett större företag. Genom att licensera ut koncepten slipper de kostnaderna för kliniska tester bland annat. Examensarbetet grundades i att ProboNova ville ha hjälp med att ta fram ett koncept på en ny sårhake. Projektet har genomsyrats av designprocessen där förstudie och idégenerering har varit de två dominerande delarna. I slutet av projektet presenterades ett koncept som uppfyllde alla krav och detta koncept togs det senare en Provisional Patent Application på. Tanken är att examensarbetet ska ge läsaren en bättre förståelse för hur man kan jobba med designprocessen och lära sig fördelarna med att välja en Provisional Patent Application istället för en Nonprovisional ansökan..
