During installation and operation of a geothermal heat pump system leakage of an antifreezing agent can appear in a borehole and leak out in surrounding groundwater. To guarantee high quality drinking water for generations to come Sweden has dedicated some areas as water protection areas. The local authority gives permits for the installation of heat pump systems within water protection areas. Before giving a permit the local authority makes an evaluation of the risks involved in installation and operation of the system within the area. By keeping a certain distance between the protected object in the area and the heat pump system the risk of polluting the protected object with an anti-freezing agent can be reduced.This thesis makes a comparison between three different methods of calculating an appropriate distance between the protected object and the heat pump system.

This essay deals with ruins from the perspective of their cultural values ??and the impact of add-ons, protective add-ons and caring actions affect these values. The issues in the essay are; What are the cultural values of a ruin?  How have ruins been used?  How are ruins treated today?Initially the definition of the concept ?ruin? is discussed, what is a ruin? A building has an architectural biography: the creation, destruction, change and the decay. The concept of ruin is considered to be a state of this decay, rather than a dead building.

Barren rearing environment and early weaning of piglets can lead to a high level of distress, behavioural disturbances and reduction in weight gain. The main aim of this thesis was to study the effects of potential enrichment objects on piglet?s behaviour and weight gain during the pre- and post-weaning period. The second aim was to examine what type of object stimulated the highest frequency of interaction. The study was carried out at the Swedish Livestock Research Centre in Lövsta where a batch of litters from 10 first-parity Yorkshire sows were used.

This thesis deals with different methods for measuring moisture-related dimensional changes ofwood. Typically relative humidity is measured to determine if the ambient climate around anobject is harmful to it or not. Values between 40 to 65% RH are recommended for hygroscopicmaterials. To know how a wooden object actually reacts to changes in the surroundingenvironment requires methods that involve the object itself. Because of the wood anisotropy,differences in wood structure, finishes and other restraints, it is not always possible to predict themovements.This paper addresses various measurement methods, primarily methods that have been testedin the field of conservation, with examples of their use.

The foundation for a museum is the collection. To collect, preserve and display is what constitutes a museum. But the process of deciding which object´s should be saved, and which objects should not, are based on values. It is also values that make people inclined to donate objects to museums. How and why we value a museum determine if and why we donate.Objects themselves could be said to have a biography just like people.

 Genotyping can be used to link genetic variation among individuals to certain diseases or conditions. Some known disorders and states that are dependent on single nucleotide polymorphism (SNPs) are lactose intolerance, venous thrombosis, hereditary hemochromatosis and the difference in sensibility among people to metabolise drugs.In this project a new kit, TaqManÒ Sample-to-SNP KitÔ for extraction of DNA and preparation of the extract for genotyping with real-time PCR and allelic discrimination, was evaluated. QIAamp® DNA Blood Biorobot® MDx Kit was used as the reference method.The purpose of the comparison was to find a method that makes DNA extraction from blood samples cheaper and faster, but with the same reliability as the reference procedure.The results of the evaluation showed a complete agreement of the genotype results between the methods tested, which means that the new method was as reliable as the reference method. The costs of reagents and material would be reduced with 52% if the new method is adopted, that alone would result in a cost reduction of 144 000SEK a year with a sample volume of 650 samples/month. The time for DNA extraction would also be reduced with the new procedure. .

Previously when I have made proposals for privately owned gardens, I have found it difficult to find strong, extensive designs and to work with room and space. Since this is the field within which I am going to work in the future I feel that I need more experience, reference material and ideas on how I, in an early stage of the working process, can work with and consider room and space. The aim of this project has therefore been to procure experience, reference material and ideas for design of a garden in relation to space. To procure experience and reference material I have, during the fall of 2008, made two incredible study tours to France and to Japan. I have interviewed the landscaping architect Maria Arborgh and studied literature. I have also used a garden outside of Gothenburg in which I have been able to try out different thoughts and ideas regarding shape that have appeared during the course of my work. My conclusions about landscaping are that you should first find the different functions in the garden. The next step is to find an overall theme or shape, use a small number of materials, build a room with sealing, walls and portals with the help of vertical elements e.g.

The object of this essay was about youth's experiences of their possibility of consumption. We also wanted to analyze if their possibility of consumption had a connection with their experience of happiness. Another part of the object was to see if there where any differences between girls and boys concerning the questions above. One of the issues we had was if the youth's money was enough for their needs of consumption. The method we used were a questionnaire, which we asked a class of 22 pupils to fill in.

Modern missiles must meet higher and higher demands. They should be autonomous, have long range and still have a big effect on the target. To maximize effect on target some missiles not only minimize miss distance, but also try to hit with a certain angle; often perpendicular to the surface of the target. In this thesis a method to guide the missile in the terminal phase of its mission where both point of impact as angle of impact are specified. The method consist of two parts.

The purpose of my Masters thesis is to investigate how childrens librarians in public libraries perceive and meet imposed queries during the reference interview with children and young people. What do childrens librarians think about imposed queries from children and young people? What problems can arise during a reference interview with children and young people, and what strategies can be used to solve them? How can childrens librarians prepare for imposed queries from children and young people that have arisen in school related situations? The study was carried out at public libraries in Sweden. In the review of the literature results from prior research and other relevant material are presented. The theoretical framework includes a communication model on imposed queries developed by Gross, and two other models Levels of Mediation and Zone of Intervention, developed by Kuhlthau.

The report handles the transmission of signals from piezoresistive pressuresensors and thermocouple from a rotating object. This report also evaluates the possibility to collect data in a datalogger that rotates with the object. Telemetrics was previously used for signaltransmission in Finspång, therefore there has been no tests considering preassure measuring. One transmitting method handled in this report is transmission through a slipring connection. One test with a slipring connection was performed for transmitting signals from a piezoresistive preassuresensor.

Den säkerhetspolitiska debatten har under de senaste åren tillvaratagit ett bredare perspektiv av hot och risker. Undersökningen tar sin utgångspunkt i frågan om i vilken utsträckning detta kommit till uttryck i svenska försvarspropositioner? Undersökningen kartlägger likheter och skillnader i tre försvarspropositioners uttryck av hot och säkerhet relaterat till det vidgade säkerhetsbegreppet under perioden 1982-2009. Vid kartläggningen undersöker jag med hjälp av Barry Buzan m.fl. analysramverk för det vidgade säkerhetsbegreppet vilka säkerhetspolitiska värden som uttrycktes vara viktiga att säkerställa.

In order for a retention of title clause (ROT-clause) to be valid against third parties underSwedish law, the debtor must be prohibited to dispose of the object transferred. Forinstance, the debtor must not be allowed to resell the object without the creditor?spermission or before the object has been fully paid. If the creditor gives consent to thedebtor?s disposal, he loses his right of separation.

The calcium homeostasis in the body is normally strict regulated to be kept within very narrow limits. This regulation is due to the action of parathyroid hormone (PTH) which is synthesized in the chief cells of the parathyroid glands. In different diseases, the calcium homeostasis is disturbed and this could either be due to a dysfunction of the parathyroid gland itself, or it could have a completely different explanation. To investigate disturbed calciumhomeostasis, ionized calcium and PTH can be analyzed from a blood sample. There are a lot of different assays to measure PTH in humans.

 My field is Korpus and in this project I am investigating what role that plays for me as an artist connected to craft. To really get close to, and understand Korpus I have deconstructed it to find clues to why the silversmithing field looks like it does and how we got here. I believe Korpus has not yet come out of the closet for what it really can be. That it carries a great heritage of traditions and preconceptions that it would do well to shake off a little bit of. Can Korpus as an art field really survive in Sweden, where the Church has no power and silverware is no longer a need to demonstrate ones economic prosperity at an important dinner party? To help myself get closer to these objects I have given my own definition of Korpus.
