Hassel (Corylus avellana) som indikator på markanvändningshistorik
Hazel (Corylus avellana L.) is a common feature of meadows and pastures where it can grow in large populations and become very old. Is it possible to use the size of hazel stools for age determination and is it possible to use the size distribution of a population to provide information about how the land has been used? Hazel populations on ground where the lake-water level had been lowered, has been studied to validate an already developed growth model of hazel clones. Different hazel populations, on wooded meadows affected by mowing or grazing or overgrown meadows, were studied to evaluate the method utilizing hazel as land use indicator. The growth model was used to compare the size distributions of hazel populations with historical periods, which has been important for changes in agriculture or demography.

"Men det är klart att man vänjer sig" : En undersökning om kvinnoprästers upplevelser av diskriminering inom Svenska kyrkan
The purpose of this essay is to examine clergywomen?s experience of discrimination within the Swedish church as to clergywomen?s opinions about their work and their work situation and how they handle contingent discrimination. The method used in this essay is qualitative, and in order to create an understanding of the topic we have used semi structured interviews and text analysis. Three clergywomen have been interviewed and in addition to this we have studied four clergywomen's reports to JämO regarding gender discrimination. The analysis is based upon a social constructivist perspective and Hirdman's gender system theory.
Genernas påverkan på köttkvaliteten
Multiple factors are involved in control of beef sensory quality so great variation can be induced. The perception of meat quality can be affected anywhere in the product chain. Both the environment and the set of genes of the animals have an effect on the final output. A problem facing the beef industry today is the significant variations in meat quality between individual animals, which is reflected in the uneven quality of the meat that reaches the consumer. If the quality of meat in stores varies significantly over time, the consumers? trust may decrease.
Opportunities for improved environmental sustainability of a wine producer in South Africa : natural resource management and climate change adaptation and mitigation
South Africa has been among the top ten wine producing countries for at least 20 years. Even though the land under grapevines is decreasing globally it is still increasing in Africa. The awareness of environment has strengthen the last years and South African producers experience a high demand of environmentally friendly produced wine, especially from the European market. This demand was the driving force behind the development of the world unique sustainability certification, Integrated Production of Wine (IPW), which is inscribed in the South African legislation. What makes this certification unique is that consumers can trace their product all the way back to the farming practices owing to the identity number specified on the IPW Integrity & Sustainability seal on certified products.
Förvildade husdjur : möjligheter och hot
Feral animal populations are distributed over many parts of the world and are often seen as a problem. Since they are a threat against other species, destroy farmlands and can spread dis-eases, they are often referred to as pests. Artificial selection has contributed to loss of genetic diversity in our domesticated animals. Feral animal populations are affected by natural selec-tion, which allows them to adapt to the environment. Their ability to adapt is a reason to see them as pests but can also be seen as an asset.
A comparison of transporters? paddle use when unloading pigs at slaughter
Today, pigs are moved on farm, between farms, between countries and to abattoirs. This movement of live pigs requires handling practices that are designed for the purpose. The objective of this study was to research the use of paddle in moving pigs, to investigate if there were different methods of paddle practice, explore the time efficiency of different kinds of paddle use and if there were any time variations in methods that varied in intensity of touch. This study was done on two Swedish abattoirs for a total of five weeks. A total of 22 transporters working at two different abattoirs where studied during unloading of pigs at the abattoirs.
Venture Capital & Banklån : Småföretagsfinansiering
There are many different forms of financing for small businesses and two common financing options mentioned in the study, bank loans and Venture Capital.Venture Capital is a form of risk capital financing, investing in unlisted stock market. The feature of the arrangement is that those people are trying to find companies that can offer unique, attractive and in demand products on a strong growing market. Since VC-firms are taking a big risk in cooperation with the investment, the VC-company strong demands while assessments are made on the company will generate a return in the future.Bank loans are the most common form of financing for companies in the market. Requirements and assessment under the law is hard especially for small businesses because financing entails high risks. Banks require that the liquidity management in the enterprise should be stable because the bank's main objective is to repayment of debt and the interest payable on the capital.The purpose of this study is to examine the requirements and assessments VC-firms and banks make use of the financing of small businesses. .
ITP - Market Entry Strategy
Forces of innovation alter the course of many industries. Currently there is a restructuring of the Swedish energy sector due to deregulation. This in combination with advanced technologies generates an innovative and a highly changeable environment. The result is differentiation of services and products. New actors are emerging and corporations grow larger.
Ask.com, Web Wombat och Yahoo: En studie av två globala och en lokal sökmotor.
This thesis is focusing on how global and local search engines retrieve information from the local domain. The three search engines tested are the global search engines Yahoo, Ask.com and the local search engine Web Wombat. The questions we examined were: which search engine has the best retrieval effectiveness? Could there be other reasons than retrieval effectiveness, to choosing a local search engine?For our test we constructed 20 questions related to Australia.We chose to divide the questions into topics like nature, sports and culture. For all questions we evaluated the relevance of the first 20 hits.
Den fysiska resebyråns framtid : En studie om de fysiska resebyråernas förändrade betydelse på resemarknaden
Purpose: The purpose of this paper is that from the physical travel agencies perspective try to see how they perceive their future, knowing that the booking on Internet has increased.Problem: What are the prospects for future development of the physical travel agency? Has the technological development affected the physical travel agency and forced it to change its role and meaning?Method: This paper has a qualitative approach. Interviews have been made with employees on physical travel agencies to try to reach a deeper understanding and thereafter be able to give us an understanding of our problem.Conclusion: The physical travel agency has been given a new role as the employees are no longer seen as sellers but more regarded to as consultants. The travel agency has become more of an information bank than just a shop where travels are being sold. Despite this change, we believe that customers will continue to visit the physical travel agents because of the unique knowledge and services they can provide that Internet not yet can offer.
En fenomenologisk studie om hur ungdomar upplever sin tillvaro, relationer och framtidsvisioner.
This project aims to obtain a deeper understanding of what it is like to be young today, and of how young people experience their lives. Identifying and uncovering the process of meaning constitution concerning young people's thoughts and feelings within each subjective individual, and their visions about the future as well as how they experience relations to other people in their surrounding, was achieved with a phenomenological approach. The participants were asked to write a self-report in answer to a carefully formulated question.The received reports were analysed according to the method of Meaning Constitution Analysis and Sphinx Lexica. The result showed that young people's lives are both complex and unique. They rather write about friends than family and write less about the future than we first assumed.
Konsumtionens klimatpåverkan : En jämförande studie mellan två socioekonomiskt skilda bostadsområden, Araby och Söder i Växjö
The world is in a stage of climate crisis where the average temperature is rising, with consequences such as, melting ice sheets, increasing sea levels, and floods. The climate panel of the UN, IPCC, has stated that this is a reaction of anthropogenic emissions of greenhouse gases. The most important gas is carbon dioxide, which contributes with 80 per cent to the on going climate crisis.The increasing emissions of carbon dioxide are connected to human consumption patterns. This puts pressure on the earth, as humans demand more and more resources. Today the earth needs one and a half year to regenerate the resources humans? demand of it, by the year 2030 we will need two planets in order to cope with this increasing demand of resources.At a global level it is established that richer countries have a stronger consumption pattern than poorer, and thus generate higher levels of carbon dioxide emissions.
En IT-forensikers kamp mot IT-brottsligheten : En studie om arbetssätt hos polisens IT-forensiker
The use of information technology (IT) is exploding. Today, it is in our daily routines to use some kind of information technology. The increase of users increases the number of cyber crimes, ie, crimes that in some way involve IT. As the cyber crimes grow in numbers, the workload for technical investigator increases, these are called digital crime investigators. The thesis is about how police digital crime investigators work and what problems they may encounter during an investigation.
MEMS baserad referensoscillator
The interest in tiny wireless applications raises the demand for an integrated reference oscillator with the same performance as the macroscopic quartz crystal reference oscillators. The main challenge of the thesis is to prove that it is possible to build a MEMS based oscillator that approaches the accuracy level of existing quartz crystal oscillators. The MEMS resonator samples which Philips provides are measured and an equivalent electrical model is designed for them. This model is used in the simulations of the Pierce oscillator and the transresistance amplifier oscillator that are evaluated in this thesis. Finally the Pierce oscillator is implemented in the A BCD2 process and manufactured at Philips Semiconductors in Nijmegen, The Netherlands.
