This thesis raises the problem with acid mine drainage around the closed mine Finngruvan.The purpose of the investigation was to compare metal content in surface water in the areaand its catchments between year 2010 and 2003, also to make calculation of specific runoffand metal load, furthermore determine the recipients in the area. Surface water samplingwhere preformed at the same place as 2003 and also at a few other places of interest. Adigital elevation file were used in GIS to calculate the area of the watersheds in the region,observations in the field where also made. The collected data were used to make comparisons,calculations and conclusions. The result showed that the surface water 2010 had somewhatlower metal concentrations.

In this paper we have studied possible future uses for Additive Manufacturing (commonly referred to as 3D-printing) in Space. More specifically we have sought to establish how Additive Manufacturing can be used to construct structures on the Moon. Our studies have shown that Additive Manufacturing has great potential for establishing colonies on not only the Moon, but perhaps even further away from our home planet. With Contour Crafting-technology in combination with ISRU (In Situ Resource Utilization) we could, with material already present in the sediment layers of the Moon, construct advanced structures without having to transfer any extra material from Earth. This would lower the costs of establishing a colony on the Moon to such extents that it could actually be fiscally possible..

1st of may 2003, a new energy system based on electricity certificates, was initiated in Sweden. The purpose with this system, is to stimulate an enlargement of energy production from renewable sources. The electricity system, ist built on that the producers of energy from renewable sources confer a electricity certificate from the government for every produced MW energy from renewable sources. The electricity certificate is supposed to be turned over and with that generate reciepts to the producers. Furthermore there is an obligation for the energyusers und energysuppliers, that means that the users and the suppliers every year the 1st of april got to have electricity certificates in proportion to their energy consumption during previous year.

Managing credit risk might be the single most important business area for any commercial bank. The assessment of "good" and "bad" corporate clients is a important task for a creditor. A bad debtor is a corporate client with hardships in meeting the continous claims (interest payments) that a creditor requires. One way of evaluating or separating a "bad" client from a "good" client is to assess the propensity for the client to file for bankruptcy. This thesis examines 226 firms in the Swedsh market in the quest of predicting corporate bankruptcy.

The purpose of this paper has been to highlight how three different highschool textbooks portrays Christianity and Islam. The aim of the paper has been to higlight and pinpoint how the three different textbooks uses different angles and perspectives on recontextualization; which ergo in turn creates a different field of transferred knowledge from each individual textbook.The paper uses an applied model of Bernstein?s theory of recontexualization, and from it derives two analytical tools to process and make an analysis of the textbooks transferred knowledge. The first analytical methodical tool of Bernstein?s theory is positioning, which is used in the paper to highlight what the different textbooks value and evaluate different kinds of knowledge of Christianity and Islam.

Idag har vi mängder av data på våra lagringsmedia vilket gör dem till en värdefull informationskälla. Om denna data raderas betyder det inte att den är borta för alltid. Data finns fortfarande kvar på lagringsmediet och går att återskapa med så kallad file carving. Att kunna återskapa data är en viktig del inom den polisiära verksamheten, men även för andra verksamheter som förlorat data. Det finns dock vissa problem som kan ställa till med besvär när data ska återskapas. När filer inte är lagrade i sammanhängande datablock blir de fragmenterade vilket innebär problem.

The domain of this thesis is Personal Information Management (PIM) which is a sub-domain to human-computer interaction (HCI) that specifically concerns the interaction between human and information. The purpose of the study is to make an exploration of information management in a scientific research setting, to study which tools and strategies for information interaction that are used in the context and to suggest possible improvements of today's practices. Three in-depth interviews with scientific researchers have been conducted followed by a qualitative analysis of the results. The results show that there are great variations among the three respondents and that there can be distinguished as much as 15 different dimensions that when put together forms a unique PIM profile for each individual. The recommendation following this is that tools for PIM have to allow a high degree of individualisation.

In my exam-project, ?For Götha Kendo Club ? an athletic clubs new graphical profile? at HDK ( School of Design and Crafts ) i chose to redesign the visual identity of Götha Kendo Club, a kendo-club in Gothenburg. Kendo is a japanese fencing sport, where swords of bamboo are used, together with protective armor.My work consists of a new logotype for Götha Kendo Club; three different posters for recruiting beginners; a website layout, presented with a pdf-file; and a beginners folder, with an introduction to kendo.The aim was, not only to give Götha Kendo Club a new fresh look, but also to attract a target group to the sport, namely people who are interested in competition, exercise and athletics.To achieve this I created a though look where tension and focus was the lead; using only three colours, red, white and black, and with progressive typography set in with the modernistic HouseGothic typeface I created this fresh and exciting look. The photography by Ida Nordung where shoot with white backdrop, creating a hard contrast to the dark clothed kendo models.Finally I collected rules and guidelines for the graphical and visual elements of Götha Kendo Club new style in a graphical guide..

This paper describes a method for wireless energy transfer via near-field electromagnetic inductionthat is inexpensive, simple and can be applied to almost any type of system, regardless of size andenergy demands.The method uses a primary unit consisting of an oscillator, amplifier and inductive coil thattransfers energy to a secondary unit consisting of a coil, rectifier and voltage regulator. Two typesof oscillators and several amplifier designs were realized and evaluated together with a multitudeof flat coils of both monofilar and bifilar type.The results show that it is important to use an oscillator whose frequency is dependent on theinductance of the connected transmission coil, such as the Colpitts oscillator. This is preferable toan oscillator with a preset frequency, such as a Schmitt-trigger oscillator..

Photodynamic therapy is a relatively new treatment for superficial squamous cell carcinoma in cats. There are no publications indicating that the method is being used in veterinary practice in Sweden at the present time. The method uses the interaction between a photosensitive agent which has been administered to the tumor area, light of a wavelength that can be absorbed by the photosensitiser and the presence of oxygen. In this study photodynamic treatments were performed at the Queen?s Veterinary School Hopital of Cambridge University between 1998 and 2002.

E-commerce is a conception who many are taking about nowadays. E-commerce is associate with computer based business and it?s a new way to do business on. Users and system connect up to each other for effective mediate and transfer information. Within e-commerce there?s a lot of ways to do business on and it can for example be between a business and a another business (B2B) or between business and consumer (B2C).In this degree report have I reached if small business will invest on e-commerce and if they will, how.

LRF Konsult is a big consulting-firm with offices located all over Sweden. The corporation offers a wide range of services and a lot of the customers are small businesses active within the green sector. An analysis of the corporation made in 2006 showed that one of LRF Konsults weaknesses is that many customers are unaware of the wide range of services that LRF Konsult offers. The internal communication is believed to play a big role in marketing these services. Therefor, the objective of this thesis has been to investigate why the transfer of customers between accounting consultants and business advisors is not greater and how this can be improved.

Chalmers University of Technology today have numerous computers which are never powereddown, at the same time there is a need for more computation power for researchers.Hence, we have investigated the possibility to use the computers for computing power andsecondly, if there is no work to be done, to put them into power saving mode.We have made a thorough study where we compared different distributing systems andin the end HTCondor was chosen as the best to implement. HTCondor is an excellent systemfor opportunistic use of computing power, i.e. make use of computers that no one elseis currently using. The system is used at several universities around the world with goodresults and would be excellent at Chalmers, where there is a need for such a system.Our implementation shows that HTCondor is well capable of handling unused computingpower. HTCondor can handle most file types that may be run on the system.

The aim of this study was to look into why children receive the interventions contact person and contact family. This was done by studying case-files. The main questions were:-       How common is it that there are reasons for the intervention linked to parents and which are the most common?-       How common is it that there are reasons for the intervention and problems linked to children and which are the most common?-       Is there any indication of connections between reasons, age, gender or type of intervention? If so, what are the connections?The main results of this study were that most of the children lived with a single mother, often with a weak social network, and in need of relief. It was more common that reasons were linked to children then parents and the most common reasons indicated a need for an extra adult.
