ABSTRACTThe fauna of the Lower Cambrian is far from fully understood, as is the environment of that epoch. Some of the most crucial moments in the history of evolution takes place during this epoch; the Cambrian explosion and the appearance of ecosystems as we know them. That makes it an important period to investigate. Doing so, the Lower Cambrian offers a lot of problems, one of which is that body fossils are seldom preserved. That has often left us with trace fossils to create an image of the Lower Cambrian life, but also some bedrock features such as ripple marks.The main purpose of this work has been to investigate the possibilities of relating the wave lengths and forms of recent wave-generated ripples to fossil ones, and also to evaluate the methods for that kind of comparison.

In the current situation is the straight tube cutter, that provides Luvata?s line of large recoolers with copper tubes, manually operated. To prevent damages and facilitate mounting the tubes must be properly arranged when they leave the machine. This report aims to investigate and present an automated solution where the operator does not need to participate in the process. A number of theories have been drawn up and tests have been done.

This thesis is done in cooperation with SWECO Energuide in Växjö. They have been assigned by SKB in Oskarshamn to renew their electrical power supply and the ancillary processing systems in their Central provisional storage of spent nuclear fuel, CLAB. Today in the CLAB facility, the spent fuel is cooled down with water pumps, driven by asynchronous induction motors, where the water is regulated by mechanical valves to the desired flow. After the upgrade, the engines will be powered by AC drives that can control the pumps by changing the rotational speed and thus change the water's cooling effect on the nuclear fuel. In this study, I investigated the interference AC drives causes the feeding network and how to go about averting them.

Partnering is a collaboration method where the contractor and the client work together, based on a mutual trust towards each other and with a common goal for the project. The method originates from the United States where it was early adapted by the U.S. Army Corps of Engineers. It later spread internationally where the United Kingdom and Denmark were early in Europe to see the potential with partnering, to help aid with the issues they were having where construction projects kept running late, going over budget and lacked in quality. By using partnering you can achieve a shorter building time, improved work relationships and enhanced efficiency and cost effectiveness.

The aim of this study was to investigate the possibility of performing inter-species embryo transfer under actual field conditions in the natural habitat of South American camelids. In this study embryos from llamas were transferred to alpaca recipients. In a parallel study alpaca embryos were transferred to llama recipients. All animals used were free of uterine and ovarian abnormalities detectable by rectal palpation and /or ultrasound examination. Embryos were harvested twice after single ovulation in 10 mated female llamas and non-surgically transferred to synchronized alpaca recipients.

Syfte: Syftet var att undersöka vad kommunikationsbrister kan bero på och hur en organisation kan gå tillväga för att lösa problem som uppstår på grund av dem. Med detta som grund har studien utformat rekommendationer för hur förvärvsorganisationer kan arbeta med den interna kommunikationen och på så sätt överkomma och förebygga brister i kommunikationen.Metod: En fallstudie utifrån en deduktiv forskningsprocess användes genom att ställa upp påståenden utifrån teorin som prövades på empirin. Datainsamlingen skedde genom kvalitativa intervjuer och en kvantitativ enkät.Slutsats: Brister som uppstår i kommunikationen har en verkan på hela organisationens finansiella och prestationsmässiga resultat. Genom att lägga beslag på kommunikationen kan en förvärvsorganisation bli mer framgångsrik..

In our modern society, time is important. Technology is used in countless ways to faster get us from one point to another. The purpose of this report is to inquire whether there is a way to implement an option for personnel at Swedish hospitals to claim priority on an elevator call, and to do this in an efficient way. An ordinary elevator system has been simulated with an implementation of textit{Nearest Car algorithm}, an algorithm which calculates the most suitable elevator car to serve a specific call considering the distance between the call floor and the car and the direction. Along with this algorithm, different ways to handle priority calls has been implemented to see how they affect the mean transport time for both passengers with priority and regular passengers in the elevator.

The purpose of this report is to compile and examine the cost of renovation of moisture-damaged bathrooms, to derive a target price. The target price can then be used by insurance companies to estimate the ultimate cost of future bathroom renovations.       The method is based on the compilation and comparison of the cost of repairs of previous water damage in bathrooms. The calculations compiled based on repair estimates for different insurance losses from one of the leading insurance companies in Sweden.       The result shows the average price per square meter of floor area for different sizes of bathrooms. The average price is the basis for the estimate of future renovation costs of bathrooms. The results further show that the bathroom finishes, area and the distance between the entrepreneur and the location of the renovation have great impact on the final repairing cost.

The goal of the project was to create an extension to Internet Explorer forStatens Tjänstepensionsverk (SPV) which would give the staff the experience ofSingle sign-on (SSO) to external web service providers as well as manage andupdate their passwords in a secure manner. The survey focused on the providersPalasso, ProCompetence and Wera. The extension was created as a BrowserHelper Object (BHO) with C# in .NET. The solution was implemented as aCOM object in a DLL-file that was running in-process with the browser. Theprogram used a locally stored XML file containing URLs, usernames andencrypted passwords to the providers.

This is a qualitative study based on two focus group interviews with a total of six social workers who work with assessing financial aid in two municipalities. The study aims to examine how the social workers experience and handle their ambiguous professional role, on the basis that they are expected to support and control the client. The theoretical framework is the theory about discretion and role theory. The results show that social workers find it difficult to combine these different approaches. Two different groups of strategies that social workers use to manage their professional role have been distinguished, the first is used to combine the different approaches (combination strategies), which are: empathy, to be distinct and to "blame" the organization.

The aim of this Master?s thesis is to investigate how contemporary Swedish picture-books describe ethnicity. The analysis is based upon eight books that were published during the period 1996 to 2006. The thesis is based upon a qualitative content analysis and a model of analysis that has been constructed with inspiration from Maria Nikolajeva and Pil Dahlerup and their conceptions of analyzing literature. The study?s theoretical framework is primarily based on the sociology of literature and the perspective of the society in literature.

In today?s society computers are getting a much more important role. To get a computer to work as intended it has to be programmed. A computer program is written with programming languages. There is an abundance of programming languages available today and there are many differences and similarities between them.

The process of drug discovery is very slow and expensive. There is a need for reliable in silico methods; however the performance of these methods differs.This work presents a targeted study on how the drug discovery methods used in OpenEye?s tools ROCS, EON and FRED perform on targets with small ligands. It was examined if 12 compounds (markers) somewhat similar to AMP could be detected by ROCS in a random data set comprised of 1000 compounds. It was also examined if EON could find any electrostatic similarities between the queries and the markers.

Our paper is targeting mainly students, but also all other people interested in social work with children. The purpose of our study was to investigate how the social workers experience and handle their work with children, who have been exposed to sexual abuse, and what kind of support and guidance the social workers are offered, in order to handle their working situation. We chose to perform a qualitative study, by the use of interviews, since we found it to be the most appropriate way to gather the information. Our conclusion is that the work with these issues is emotionally burdensome and requires a great commitment, however it is essential for the social workers to maintain a certain distance to their work, in order not to influence their personal lives. It is through experience and knowledge that the social workers learn how to handle their working situation.

It is through experience and knowledge that the social workers learn how to handle their working situation. We also learned that although the work with sexual abuse against children gave birth to different emotions of the social worker, the social workers feel satisfaction with their work, by helping the exposed children. We hope that our paper will inspire and encourage to further studies in the area, since there is still much to be explored. .
