This paper aims to derive the Black-Scholes equation for readers without advanced knowledge in finance and mathematics. To succeed, this paper contains a theoretical chapter in which concepts such as options, interest rate, differential equations and stochastic variable are explained. This paper also presents the theory of stochastic processes such as the Wiener process and Ito process. In the chapter on the Black-Scholes model the Ito process is used to describe price of shares and with the help of Ito's lemma Black-Scholes equation can be derived. In the paper, assumptions are listed that apply to the Black-Scholes model and then uses the Black-Scholes equation to calculate the price of a European call option.

The nitrogen cycle in freshwater bodies is complex and consists of many separate processes affected by a number of important factors for example oxygen concentration in the water, temperature and circulation. Knowledge of the different components of the nitrogen cycle exists; however, a complete and comprehensive picture is difficult conceptually as well as theoretically. The available literature illustrates that the research on nitrogen and the related freshwater processes is still associated with high uncertainty of how much of the supplied nitrogen from the catchment is transported with the water versus and how much is lost due to denitrification, sedimentation or uptake by plants. This report is an interdisciplinary survey of Nitrogen discharge permitting. The research focuses in particular on the decision-making process, the levels of scientific standard and the administrative framework.Application for Nitrogen discharge permits are decided by the Environmental Court with council from their own experts as well as relevant government authorities and organisations.

Individual cellulose ?bers were studied to identify the transport and absorbtion phenomena as well as the in?uence of drying. A Chalmers University of Technologydeveloped method within ESEM (Enviromental Scanning Electron Microscope) has been used in this study. The results from the laborations gave the following conclu-sions: The transport of water occurs in ?bers in the ?ber wall surface and the lumen.

There are differences today amongst psychoanalysts regarding if psychoanalysis should limit itself to being exclusively a hermeneutic discipline or if psychoanalysis should find points of contact with neurobiology. The purpose of this essay is to touch upon the larger issue that creates the different points of view: Can psychoanalysis become enriched by finding points of contact with neurobiology, and should psychoanalysis be regarded as belonging to a broader scientific field than being exclusively a human science? The question at issue is: Can modern neurobiology contribute to a development of the psychoanalytic concepts; compulsion to repeat, transference/countertransference and talking cure? The method used is a literature study. The result shows that: Freud?s theories regarding traumatic compulsion to repeat can be linked with LeDoux?s theory of "emotional memory".

The North-American sociologist Michael Lipsky has characterized social workers as street-level bureaucrats with a substantial discretion in the relationship between the welfare state and its citizens. Within Lipsky´s theoretical framework social workers appear as a powerful group that socializes the citizens to uphold certain expectations towards the welfare state and its (re)distributional programs. From this point of view, it is important to learn more about social workers and the attitudes they express towards the welfare state. The aim of this study is to analyze how the welfare-political attitudes of future social workers are affected by their social background (e.g. class background and ancestral homeland).

Alternative splicing is a process that partly rejects the common definition of a gene ? that one gene codes for one specific protein. By variable combination of coding regions (exons) and exclusion of non-coding regions (introns), formation of several different mRNA-transcripts, and consequently several different proteins, can derive from the same gene. Alternative splicing is an important condition for the development of complex life forms, but it is also a highly sensitive process and inaccurate splicing is the cause of approximately 15 % of mutations that cause genetic diseases. This article presents four genes, BRCA1, BRCA2, ER? and ER?, and inaccurate splicing of these genes increases the risk of developing cancer, particularly breast cancer and ovarian cancer.

Since the 1980s, companies have taken a larger interest in quality and it´s economic impact within the company. Having the knowledge that it´s not quality that costs money, but it´s rather the lack of quality. The work immerses itself in the field of cost of poor quality and the development of key performance indicators.The thesis is performed at Bufab Holding in Värnamo. Bufab Holding is a trading company which mainly buys and sells C-parts. C-parts include fasteners, other small metal-, rubber- or plastic parts such as wires, springs and electronic fasteners.The aim of this thesis was to make a survey of the cost of poor quality and to find key performance indicators (KPI) for cost of poor quality that can be continuously monitored.

Background: The last few years a globalization of the capital market has occurred. This have led to that it is more important for the companies that their financial information can be compared with other companies in order to compete on same grounds. In order to fa-cilitate for the companies within EU to compete with other companies and in order to strive for an internal market EU decided that IFRS should be used by all listed companies within the union.Problem: In 2006 the first financial reports according to IFRS will be published, and then it will be interesting to investigate how the companies have chosen to communicate the transition to its stakeholders. According to IFRS some information is compulsive but the companies have chosen to disclose voluntary information to a different degree.Purpose: The purpose of this study is to describe to what extent the Swedish listed com-panies have reported the transition to IFRS in their consolidated financial statements.Method: In this essay a quantitative method have been chosen in order to find general re-lations. The data collection is done with help of an evaluation model that have been devel-oped for this study.

The purpose with this study is to examine and analyze the eldercare staffs conceptions and perceptions about the construction of ethnicity and aging, in Swedish eldercare, to illustrate the process of othering. The authors interviewed eight people who work in the eldercare by using a vignette. We have analyzed our result from the interviews through several theories and earlier research pertinent to the subject. The study has shown that eldercare staff through their conceptions and perceptions unconscious been conducive to make and recompose constructions of ethnicity and elder. The constructions of ethnicity and elder can be conductive to processes of othering..

The aim of this Master?s thesis is to present guidelines for making a digital repository. To attain this, useful factors for creating an archive were examined. Also different organisations? strategies were analysed.

The aim with this essay is to examine in which way self-realizing and solidarity can bereconciled in a multicultural society. The essay is a sociological literature study whichexamines the self- realizing process and puts it in a multicultural perspective.The issues areWhich role does self-realizing play for solidarity?How is solidarity created in a multicultural society?Can everyone be self-realized in a multicultural society?Conditions and problems for self-realizing processes are examined and are treated mainly onthe basis of Jeffrey C. Alexander and Axel Honneth theories. In the essay is established thatself-realizing and society-solidarity is mutually interdependent and that solidarity requires aform of shared value, but it doesn?t need to be based in the traditional values that commonhistory, ethnicity or culture.

This study has investigated the possibilities of implementing lean in a division of a hospital in Stockholm. The goal was to reduce the lead time for the patient to get his diagnose by implementing lean in the two production flows of this division. In order to accomplish it, a complete map over the value stream has been done. With the help of the value stream map and lean theory a list over the processes in contradiction with lean has been made. Finally propositions to implement lean and by this way reduce the lead times in this stream have been made out.

Mammary gland neoplasia is one of the most common diseases in the bitch and the most common neoplastic disease. More than 13 % of the female dog population in Sweden suffers from mammary tumors during their lifetime. The disease can affect bitches in all ages but most often middle aged and older dogs. Some breeds such as Poodle and English Setter are predisposed for the disease. The aim of this study was to evaluate if it is possible to improve the post surgical healing process by using a pressure pad.

Det framgår av en mängd opinionsundersökningar att vi svenskar ser oss som miljömedvetna. Ett sätt att värna om miljön är att källsortera. I kvarteret Topasen 1&2 i Norrköping har det införts källsortering i miljörum på gården men möjligheten att använda sopnedkasten finns kvar. I denna uppsats undersöks med hjälp av intervjuer och en enkät vad som styr de boendes val av sopsystem samt hur hyresgästerna påverkas av att kunna välja. Uppsatsen syftar till att undersöka om de boende i området gör så mycket för miljön som de tycker att de borde göra samt om deras beteende stämmer överens med vad de säger att de gör.
