The purpose behind this work was to investigate whether I could from a practical approach to create desire for mathematics among students in primary schools. I wanted also to find out how students feel about their current mathematics teaching. By introducing an equation game, and interviewing students to find out their perception of their mathematics teaching, I was able to answer my questions. What I came to was that through a practical and laboratory work, I could create an enjoyable educational opportunity in mathematics. Then during the interviews I also learned that students had not a pre-determined negative attitude towards mathematics.

Allteftersom 3d-animerade produktioner blir alltmer vanliga både i film och i TV-produktioner och datorer blir kraftfullare varje år: så börjar realtidsrendering bli mer och mer aktuellt. I detta examensarbete kommer jag främst att koncentrera mig på att skapa koncept, modellering, texturering, behandling av material och ljussättning av en prototypkaraktär där målet är att se om det går att uppnå en så pass hög kvalité på det visuella, att det går att använda i en professionell produktion och om detta inte uppnås: ta reda på vad som saknas. Resultatet är en karaktärsmodell med en tecknad visuell stil med tillhörande återanvändbart material, som förhoppningsvis ser tillräckligt bra ut för att kunna användas i till exempel ett animerat barnprogram på TV.

It is mainly high levels of androstenone and skatole in adipose tissue that is the reason behind boar-taint, which is an unpleasant odor and taste from the meat of adult male boars. The purpose of this literature study is to provide an overview of current knowledge about the physioloical functioning of androstenone. There are several studies showing androstenone´s function as a pheromone, and that it is an important part of communication and mating behavior between pigs. Androstenone is produced in the testes of the boar and transported via the bloodstream to the salivary glands where it is excreted with the saliva. Sows sense the pheromone, not via the vomeronasal organ as previously considered, but via the olfactory mucosa.

I denna undersökning, om begrepp inom ljuddesign som kan bidra till ett dynamiskt narrativ, ser vi kadenser som en möjlig metod att arbeta utifrån. Med tanke på hur man arbetar med ljud och musik i ljudmotorer till spel kan vi konstatera att kadenser kan vara passande för förmedling av narrativ. Det kräver dock att man förstår kontexten, där kadenserna förekommer. Vi har kommit fram till ett sätt att förklara ljuddesign genom en samling av teorier, akustiskt timmer, dvs. hur man kan förmedla något med ljud, antingen fristående eller tillsammans med ett annat medium..

Cattle used for meat production can be held outside all year round and due to the legislation they should have access to shelters or other buildings for protection against the elements giving them a dry and clean bedding. There are different opinions concerning their need of protection and the question about necessity of shelters for cattle is of current interest due to a less profitable economy in meat production and the investment costs for shelters. The aim of this study was to acquire more knowledge about the natural behaviour of cattle concerning their use of shelters. The basis of the study was a series of questions regarding when animals choose to stay in shelters, if shelters were used less when they had access to protecting vegetation, how temperature and weather conditions affected the use of shelters and the influence of distance between shelter and feed. Behavioural studies was conducted at five different farms where six groups of suckler cows and heifers of following breeds and crossbreeds were observed; Aberdeen Angus, Charolais, Hereford, Scottish Highland Cattle, Simmental and the Swedish breeds SKB and SRB.

The purpose of this study is to perform both a quantitative and language philosophical analysis of the folksono-my and the tags in the Stockholm public library catalogue, which together with the Umeå university folksonomy, and the folksonomy of the Norrköping public library are the only library folksonomies in Sweden.The purpose of the first part of the study is to perform an analysis of the linguistical structure of the tags in the folksonomy. To do this a quantitative analysis has been conducted to grammatically categorize and evaluate tags using a method based on Louise Spiteri?s article ?The structure and form of folksonomy tags: the road to the public library catalogue? and the SAO guidelines. This part of the analysis aims to answer questions like: what characteristics do the tags in the folksonomy have and in what ways do they separate themselves from subject headings in a controlled vocabulary? Tags were here categorized according to grammatical properties like parts of speech and their social and private characteristics.

Shareholder value has its origin in the American corporate governance system and has been the subject of great debate over the last few decades. The proponents claim that it creates economic efficiency while the critics argue that maximization of shareholder value jeopardizes the long term survival of companies. However, the debate in Sweden already seems to have forgotten the question of how embedded the ideology really is and what´s leading its way. This study show that shareholder value has developed and been established in Swedish companies between 1995 and 2005. The study has found evidence that suggests that the development can primarily be linked to board networks and international exposure.

Pets like dogs and cats have a considerable importance for humans and research demonstrate a variety of positive economic and social effects in society due to our pet companions. The presences of pets are increasing on a global scale with correlation to economic development in low- and middle income countries. For example dogs have doubled in India over a five year period. The feed industry for dogs and cats is also the fastest growing sector in the food industry and certain pets have a significant animal protein intake which, depending on the choice of resources may provide a high ecological footprint. Examples of environmental effects with distribution and manufacturing of pet food are increased greenhouse gas emissions, waste, use of water and energy.

Companies and projects often face the challenge of creating something new to increase their competitiveness. In this process of creating something new creativity is an important factor. By using a creative approach and utilizing creative processes new innovations emerges. An industry that has grown in recent years is the computer games industry. Competition is fierce and for the companies to succeed, the product need that extra something to make it stand out among all the produced games.The project manager's role in the creative process and the ability to be creative within a distance based company is not something highlighted by previous research.

The use of forage maize has increased over the last years. The aim of this litterateur review was to summarize a part of the research that has been conducted on forage maize for growing cattle, including cultivation and conservation of the maize. The forage maize is planted in April or the beginning of May when the temperature in the soil is between 6 and 10°C. Maize needs high temperatures and much water. Maize is harvested in the autumn when the dry matter (DM) is more then 30% or the plants have been exposed to the first frost in the autumn.

Sweden?s animal legislation was adopted in 1988 and is one of the most rigorous legislations in the world. Despite this, Sweden import beef from countries where animal legislation is not in accordance to the Swedish legislation. The meat consumption in Sweden has, just like the importation of beef, increased while Sweden?s own beef production has decreased.

This study aims to research how upper secondary pupils interact while playing online games, how the English language is used within each game and what attitudes these pupils have towards language in school and online gaming respectively. Online gaming sessions have been recorded to analyze the methods of interaction by which people communicate with each other while playing online games. Furthermore, the text-based communication occuring in online gaming is analyzed on a lexical level to find words not defined in legitimate English dictionaries. Interviews with students have been conducted to understand the attitudes held by students towards language in school and online games..

The purpose of the thesis is to demonstrate how high frequency trading affects the stock market. The growing high frequency trading is affecting the game plan on the financial markets and concerns have grown about the high frequency users intentions with their business. It is difficult to receive an overall picture of the subject because the lack of previous research and even the research that exist do not show the entire picture. The thesis contributes to the research through a comprehensive picture of the present debate as well as the previous research through a literature study. Our results showed that high frequency trading provides liquidity to the market, there is a statistical connection between high frequency trading and volatility, no price manipulation is being used and there is a need for a supervision of the high frequency trading..
