This report examines some common or otherwise interestingnon-cryptographic hash functions with respect to the number of collisions when used in hash tables for different types of hashkeys. The report answers which of the examined hash functions can be seen as the best performing for the chosen hashkeys. To compare the different hash functions, an experiment which studies avalanche effect behaviour is carried out. The experiments also calculate the fraction of colliding hashkeys, and the distribution of hashkeys in hash tables is studied using Karl Pearson?schi-squared test.

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.

In this study I have brought up what pupils within vocational training, with focus on upper-secondary school have apprehended about the course ?Projektarbete 100 p? (Project job 100 point). In my analysis I interviewed twelve pupils from upper-secondary school who had 20 % or more truancy during their three years of studying in upper-secondary school and achieved a result to these pupils had problems with absenteeism then primary school. The pupils agreed about the school?s existence but they need schools of practical type.

Zakrisdal and the west coast region of Karlstad was at one time a protected area where the ammunition factory AmF Zakrisdal 1941-1994 was situated. This factory manufactured explosives for the Swedish armed forces and for export. In this context it is an interesting paradox that the production of ammunition, mines and armorpiercing grenades for more than 50 years has preserved the environment surrounding the factory.The factory is now gone and the production is moved to Karlskoga. Plans are being made to build housing for 3-4000 residents and other enterprises within the area. The area now stands before yet another change, most likely the most profound to date.The inspiration for this work comes from the economic historic Jan Jörnmark.

The purpose of this paper has been to examine the question whether accountants differ in their auditing depending on their individual characteristics. We have summarized our own theory based on previous research and our own ideas. To conduct this purpose we used a deductive method. Our findings from the study show that we cannot exclude the possibility that accountants vary in their auditing depending on their individual characteristics. The answering frequency to our survey was only 47 %, and this may have affected the outcome of our research.

The following thesis concerns the conceptualization of openness within the open access movement. Open accesscan be understood as a phenomenon or a movement that aims at changing the current system of scholarly communication.Consequentially, the movements goals arose in relation to the escalating serials crisis in scholarly communicationand the increasing power of commercial publishers. The purpose of the thesis is to study three centralopen access declarations with the aim of uncovering the different conceptualizations of openness found withinthese texts. Leaning on the theoretical position known as actor-network theory, the declarations role within a surroundingnetwork is explored by focusing on how openness as a concept has been produced and reproduced bycentral actors. Two overarching questions frames the study: How is openness conceptualized within the declarations?And how can openness, as a concept, be understood as an effect generated by a larger network?The first part of the study focuses on the first question.

A plant's defensive ability against herbivore attack can be influenced by many different factors, one of them being domestication. During human selection to improve the yield of plants, the resistance against herbivore attack can have been lowered, due to a trade-off for use of resources between these traits in the plants. In this thesis I investigated the effect of domestication on resistance against herbivorous insects in cotton plants. I used different varieties and species of wild and domesticated cotton in three different experiments. A feeding assay was conducted, the mortality, development time and pupal weight of larvae of the Egyptian cotton leaf worm Spodoptera littoralis was studied. In a second experiment the preference of the root-feeding beetle Agriotes spp.

Wetlands are important ecosystems and form habitat for both common and threatened species. In Sweden, as well in many other places on earth, there is a lack of wetlands. There is an expressed will to adjust this lack through restoration of wetlands with reduced function and through construction of new wetlands. Follow-ups and evaluations are important steps to optimize these actions. The wetland Vattenparken was constructed 1999 ? 2000 for treatment of surface water.

Interactive media is constantly increasing in our surroundings and with the innovation of touch-screens, two-way communication with screens has become part of our daily life. Still, this well known way of process information is not often seen in the in-store environment of grocery retailing. Here, interactive media is an unestablished field where empirical studies are invisible within the academic world. The lack of knowledge in which effect interactive digital signage has is one of the barriers of investing in this marketing solution in-store. The main purpose of this study is to examine and describe the effects of interactive digital signage at shelf within grocery retailing.

My intention with this essay has been to examine how men?s tears are portrayed in three chosen films and what their crying does to their masculinity. In my analysis I have used the concept of hegemonic masculinity. I have worked from the assumption that in our culture men?s crying is problematic in some sense.

Effects of Menstrual Cycle and Oral Contraceptives on Sport Performance During the menstrual cycle, there is a variation of the female steriod hormones estrogen and progestogen. These hormones has mainly reproduktive functions, but do also affect other physiological systems, which may have an influence on athletic performance. The use of oral contraceptives among female athletes matches the use among the general population. There is a concern among female athletes and there coaches weather oral contraceptives can affect the performance. The purpose of this litterature review is to determine the effect of the menstrual cycle and the use of oral contraceptives on athletic performance.

Functioning reproductive organs are essential for the survival of a species. The reproductive system is very sensitive to exposure of chemical substances of anthropogenic origin. Humans release great amounts of chemical substances to the environment by our means of life and these substances have been proved to have a negative effect on the reproductive ability of different vertebral classes. In the polar bear (Ursus maritimus) a declined reproductive ability as an effect of decreased testosterone levels and decreased testicular size has been connected to the presence of high levels of organohalogenic compounds like PCBs. Although the Swedish brown bear (Ursus arctos) is not as carnivorous as its close relative the polar bear it is still exposed to environmental.

Storage of biomass is often associated with problems such as heat development, dry matter losses and reduction of fuel quality. The rise in temperature can potentially cause a risk of self-ignition in the fuel storage. Moreover, emissions from storage piles can cause health problems in the surrounding. The dry matter losses and reduction of fuel quality can have economical effects. The aim of this thesis project is to develop guidelines on how to store large amount of biomass at Vattenfalls heat and power plants in an optimal way.

Soils in a metal contaminated site on Stångberget in Gusum in southeastSweden were investigated and compared to relatively unaffected soils a fewkilometres away. Pollution came from historical release of untreated flue gasesfrom a brass mill. The objective was to find information on how high the metalconcentrations are, if metals from the polluted soil affect the surroundings andif the metal contamination affects the microbial community. The soil wasinvestigated using several different methods, such as field XRF measurements,chemical analysis of metal, carbon and nitrogen content, pH, acid neutralizingcapacity, texture, soil depth, field leach tests, sequential extraction and microbialfunctional profiles. The study showed that copper and zinc concentrationswere above Swedish Environmental Protection Agency guidelines for lesssensitive land use on the entire investigated area.
