The market for heavy duty engines is constantly requiring engines that should be more andmore powerful, while still maintaining low fuel consumption. As a result of increasing enginepower, the engine and coolant temperature increases as well due to insufficient coolingperformance (because of design issues, cost etc.).Also, emission legislations, both current and future, require more and more measures to betaken by engine manufacturers. One way of meeting the legislations is the use of cooled EGR(Exhaust Gas Recirculation), which also lead to increased coolant temperatures.Both these factors also naturally lead to increased engine oil temperatures, the consequencesof which are not thoroughly investigated.This thesis project aims to investigate effects of high temperatures on engine oil degradation,with focus on the greatest degradation process: oxidation. To do this several engine runs havebeen performed on a 310 hp engine with EGR to see what happens to the engine oil in a realengine when exposed to high temperatures. During the tests oil samples have been taken andanalysed for important parameters.As a complement to these engine tests some laboratory oxidation testing have also beenperformed, to be able to compare engine test data with laboratory tests.One goal of the project was to try to formulate an empirical oxidation model, which would beable to predict oil oxidation levels in an engine, given any running parameters.

This thesis is divided into two parts. Part one contains a general description of the flexographic printingtechnique. Part two contains a more detailed investigation in the areas substrate, inktransfer and trends, which are only briefly commented in part one, and conclusions and comments.The major problem concerning substrate is washboard. This phenomena can be limited if one can control and minimize the amount of glue applied in the single- and double facer, use high surface weight on liner, use low surfaceweight on fluting and control the humidity during the conditioning of the corrugated board. Corrugated board with a smooth surface radically increases the quality in print.

Background: The hotel market has become undiversified and the competition has increased rapidly. At the same time the environment aspects has been given higher priority and the trend continues to extend. A green marketing strategi has proven profitable if the company achieve a high credibility.Problem definition: What factors are important for hotel companies to attain long term business survival trough a green marketing strategy?Purpose: The purpose with this paper is to, trough a case study of Scandic Hotels analyze and find the relationship between trustworthy environmental work and internal factors.Method: This study is based on both qualitative and quantitative research methods. The qualitative data has been gathered through interviews with five different levels of personel, both management and employee, within the company.

BACKGROUND: Today?s societal changes, including high rate of change and increasing information flows, are increasing the demand on the individual mental capacity. It becomes increasingly difficult to analytically process all the different dilemmas and everyday decisions as individuals have a limited mental capacity available to make these decisions. Thus, it has been suggested that ego-depleted relies more heavily on intuition, which is less burdensome, when making decision. However little is known about to what extent intuitive decisions differ from analytic.

The background to this final thesis is that our mandator, A-hus, was interested to examine which roof system that would be most appropriate to their types of houses. To investigate this, we first conducted an evaluation of the most commonly used roof systems in Sweden today: decking, board, roof cloth and prefabricated roof cassettes.To gather information about the different systems we have conducted interviews with several professionals within the construction industry, done an extensive literature study, and gathered information from the Internet.Based on the evaluation of roof systems and the literature, we analyzed advantages and disadvantages of the roof systems from three main perspectives: system characteristics, economics and other characteristics. We found these perspectives to be the most relevant when selecting a roof system.The main perspectives comprise three categories which are graded. These grades are then added together for a score for each main perspective and a total score for the three main perspectives. Then we compared the systems and, based on the scores, suggested one roof system as the most suitable for A-hus.Our result suggests that the prefabricated roof cassettes probably is the best solution for A-hus, but only if it is possible to standardize the cassettes and still maintain the flexibility to match A-hus? house types.

Background: Earlier studies show that nurses work environment is a factor that may affect the quality in nursing care negatively. Other factors are: number of employees, working hours, work structure and planning and working relationships between colleagues. Work relationships are particularly important for nurses as they can affect patient safety. Nurses are prone to stressrelated illnesses and high stress levels prove to have a negative affect on the quality of nursing care. To develop and assure the quality demands effort from every employee.

The main aim of this thesis is to examine what motivates people to become entrepreneurs and how they are motivated to continue being it. We have decided to focus on four elements: the driving force of being an entrepreneur, the environment, the individual background and important personal characteristics of the entrepreneur. Qualitative interviews were carried out with six information consultants. The theoretical background has its focus on entrepreneurial motivation. A model of entrepreneurial motivation by Naffziger, Hornsby and Kuratko 1994 is presented.

The aim of this bachelor?s thesis is to analyze if there are differences in the way of explainingthe causes of The Great Emigration from Sweden to America in the late 1800s/beginningof the 1900s. Due to the researcher?s education the thesis has a didactic, and comparativeperspective between how history textbooks aimed for Middle School and High School andhow the exhibition Drömmen om Amerika (= The Dream of America), in Vaxjo, Sweden,explains this phenomena. A special analysis scheme is applied to the sources in a way to makeit clear to the reader how informative they are and how much effort they put in the explaining.The outcome of the analysis shows that the exhibition gives the visitor a wider, deeper,and more informative depiction of The Great Emigration, compared to the textbooks? moresummarized extracts.

Nowadays, the world around us is changing faster and faster, the globalization is increasing and harder competition puts extra pressure on companies to be more innovative than ever before. One of the fastest changing industries is the IT industry where the actors always have to be up to date to keep their competitive advantage. The authors want to find out what makes some companies in this industry more innovative than others by examining what internal elements that are necessary for innovation. Much research has already been carried out within the field of innovation and especially about innovation management, although less research exists about smaller, non high tech service companies. Therefore the authors also tries to find out how applicable today?s theories are on this special field and thereby fill a smaller gap in today?s research.

Bovine Respiratory Syncytial Virus (BRSV) is a common cause of respiratory disease among young cattle. The virus causes severe losses; the herd mortality rate can sometimes be as high as 20 %. In this study the avidity (i.e the antigen binding force) of BRSV specific antibodies was measured to see if there was a difference between antibodies produced during an acute phase of infection and antibodies produced by earlier infected animals. A commercially available ELISA-testkit against BRSV-specific antibodies was used and an incubation step with 6M urea was added. The effect of the urea is that it breaks the weak bonds between antibodies and antigen while the stronger bonds remain intact. Four different groups of animals were included in this study; seven calves that were naturally infected, three acutely infected calves with known time of infection, five cows that were seropositive during several years and four experimentally infected calves that had been a part of a vaccine trial. The results of this study showed that antibodies produced during the acute phase of an infection had a low avidity and that the avidity increased with time after infection.

In this master thesis we suggest a recreational directed forest management plan for the Skedalaskogen. The forest is situated 10 kilometres east of the city of Halmstad and is owned by the municipality. We have in literature and in research investigated what people like and want in the forest, how to manage the forest for recreation according to for example tree species, mixtures and density. We tried to adapt the forestry methods more to recreational thinking. We have also looked at issues like what is rare and not rare in this part of the country according to nature and forest, where people live and which connection they have to the Skedalaskogen. The Skedalaskogen is a quite big area, totally 830 hectares. The area have about 100 000 visitors a year.

The aim of this study was to describe preferences of geographic direction of ten, oak-living epiphytic lichen species and how they responded to sun exposure, nearby bushes and trees, bark fissure depth and circumference. The frequency of every species was recorded in arcs of ten degrees around the tree at a height of 130 to 180 cm above the ground. An estimation of the amount of every species in every arc was also recorded. To analyse how the distribution of the lichen species responded to the different factors their concentration for every tree was plotted against the four factors. The distribution of Cliostomum corrugatum had a positive response to high sun exposure and a negative response to a thick layer of bushes and trees.

This report is the result of a case study at Peltor AB during the spring semester of 2007. The task Peltor gave us was to improve the delivery accuracy and to lower the high finical value of delayed orders (backorder), and to divide the products into logical groups. The logical group will be a useful tool to remain a high level of service. If the level of service increases the company will be more competitive.The electronic department at Peltor has problems with delayed orders. According to Peltor, the problem is based on delivery lead time which is presumed.To increase the delivery accuracy, a lead time analysis is made to find the accumulated delivery lead times for each product.

Several factors affect the heifer´s growth and development, the newborn calf´s feeding of co-lostrum during its first hours of life is one important factor. The colostrum contains higher amount of immunoglobulins and insulin growth factors compared to matured milk. A high intake of immunoglobulins from colostrum results in a high blood concentration of immuno-globulins until the age of eight months. This leads to a lower incidence of diseases that can affect the growth and development negatively. Diarrhea is the most common disease in calves younger than 30 days.

One of today problem at IVT industries would be assembly of insulation on water cisterns. The element of assembly insulation on the cistern gets too elevated; hence one has to climb onto the stand the cistern is assembly on. This will increase the risk of work related injuries when there is a risk of falling down. It?s also rather strenuous on shoulders due to work with your arms high above your head.
