Researchers at Karlstad University have developed a method for making paper ion conducting. The reasearchers want to test this technique in various applications and produce products that make use of the ion-conducting paper. Hopefully this will drive the development forward and result in new applications for the ion-conducting paper.This study was to test the possibility of manufacturing a gas sensor of conducting paper along with electrodes of conductive polymers printed on the paper. By comparing the paper sensor with an electrochemical cell in which the electrodes of conductive polymer replaces electrodes of metal and ion-conductive paper replaces the liquid electrolyte in the electrochemical cell, it was hoped that it would be possible to measure the oxidation and reduction reactions that a gas could introduce at the electrodes.It was shown that it is possible to measure a potential difference in the range of 0.3 V to 0.5 V between the electrodes when exposing an electrode to 100% oxygen. The reaction that takes place is relatively slow and the reaction rate is partly due to the distance between the electrodes.Since the sensor can measure oxidation and reduction reactions it is possible that, in further development of a sensor, the sensor can be made ??into a versatile sensor with more applications than gas measurement as there are many more ways to oxidize or reduce the electrodes than by exposure to oxygen.During the study there have been discussions and meetings held with various companies in the sensor industry to be able to specify what the market demands of a sensor made ??of paper and the requirements that must be placed on the sensor for it to be interesting for the companies..

The field rehabilitation in veterinary medicine has expanded over the past ten years. Animalswith disorders in the musculoskeletal system are often treated. The methods used lacksufficient scientific documentation; however claim to affect the animal's function in a positiveway. In order to investigate the efficacy of different rehabilitation modalities, it is important touse validated evaluation tolls. Therefore, a literature study on pain, pain-scales and functionaltest was performed together a pilot study on a functional test.The aim of the present pilot-study was to investigate a functional test, "Bioarth functionalevaluation scale", used in veterinary medicine.

The wild boar (Sus scrofa L.) has expanded across Europe and Sweden in the last decades. It is a generalist species which utilizes a variety of habitats, and its presence has been shown to have both positive and negative effects for people and the landscape they are in. The abundance and increase of wild boar has previously been shown to differ between counties in Sweden, but there have been few explanations as to why. In this study, I investigated correlations between the per capita rate of change (r) among wild boar populations in Sweden and a variety of different habitats on the county level. I also investigated if fragmentation per se or in certain habitats could be associated with the wild boar?s per capita rate of change. My results show that fragmentation/diversity per se was not correlated with wild boar r.

The use of information technology (IT) has expanded to be available in large parts of the society.With reference to this mobility has become an increasingly used term, which reflects changes in our lifestyle, travelling and mobile artefacts. The technology development that has occurred in recent decades has made it possible for people today to be more mobile than before as they no longer are tied to a fixed workplace. Mobility has changed the ways to lead, coordinate andmeasure work productivity in organizations. It has also added new ways of working. The mobile development also means more challenges and changes in today?s modern organizations.The purpose of this paper is to analyse how employees in a consulting form use mobile technology in a work context, how they interact with others and how individuals reason about mobility.

Interest in the implementation of AGV-systems (Automated Guided Vehicle) has in recent decades increased. The reason is that it allows companies to perform reliably and secure internal transport while reducing the need of personnel. It is one of todays most advanced and complex material handling system that can independently make their own decisions regarding flow paths and traffic control. An AGV-system consists of transport units carrying cargo from point A to point B, and communicates using a computer.The purpose of this study is to develop a model on how to proceed in order to design an AGV system in heavy industry. The model is tested by a case study of a company in the metal industry to determine if the model works and gives the correct result.

The study examines the massacre of the garrison of the castle of Kalmar in 1525 and its causes. The goal of the investigation has been on the one hand to elucidate the most probable sequence of events, and on the other to identify as many different plausible explanations to the massacre as possible. For this end, four contemporary sources have been examined and compared in their details. To enable a broad basis for interpretation, the author has consulted various works on the themes of warfare, soldiers and violence in the late middle ages and the sixteenth century. Apart from political aspects, the study highlights social and cultural conditions as important factors in explaining how the massacre could be carried out without provoking any single part of society.

In 1984 the Swedish government introduced a special law which gave tax benefits to foreign researchers who for a limited time was engaged in research or development work in Sweden. The purpose was to facilitate for companies to recruit skilled employees from outside of Sweden and to make Sweden more attractive to this important group of researchers and to strengthen the Swedish competitiveness. In 2001 the law for foreign researchers was reformed to include foreign experts, researchers, managers and other key personnel. In Sweden called ?expert tax?.As a result of this; problem with the predictability of who may have the potential to apply for the expert tax benefits was developed.

The aim of this study was to examine the current and historic mercury(Hg) load of the lake Storjuktan due to its recent exposure to a local potential source of Hg in form of the Sulphide mine Blaikengruvan(2006) and an earlier potential sources of Hg-load, the damming of the lake(1960s). Sediments were extracted using a HTH-sampler, freeze-dried, and analyzed for tot-Hg, LOI and activity of 210Pb and compared to samples extracted prior to the opening of the mine(2006). Constant initial concentration (CIC)-dating model was used for dating the samples. Low levels of Hg (100ng/g) were found throughout the lakes sediment. The highest levels of Hg(220ng/g) was detected at a depth of 4-5cm dating back to the mid 1970:s, suggesting that increased levels of atmospheric Hg rather than damming of the lake has caused the increase of Hg.

The work place is becoming more flexible and an increasing number of employees report to a leader in another location or country. The borders between different countries, work places and cultures are diminished to a greater extent than before. Working from a distance means new opportunities in terms of competence development, flexibility in working hours, tasks and resources, a larger platform for various career opportunities and an expanded network. The purpose with this study is to examine how leaders can create a successful virtual team and motivate remotely. The qualitative study is carried out through interviews with leaders and employees within Nielsen Nordic.

For several years Uppsala University together with several companies has been involved in a WISENET project aimed at improving railway transport security. By placing a sensor system near the wheels of each wagon, the temperature of the bearings can be measured and transmitted to a collector placed centrally on the wagon. This in turn transmits the collected data to RFID receivers placed intermittently along the railway.As the signals are transmitted wirelessly, problems may occur as the antennas get dirty or coated with ice and snow. To determine the effects of these coatings, several tests were performed examining the reflection coefficient S11, the impedance Z11 and the efficiency eta of an antenna, and how they varied when various coatings were placed over the antenna. Examined coatings were ice, snow and water to determine the effects of weather, and various metal-based coatings: powdered iron both pure and partially oxidized, and iron ore granules.

Until recently, the art market has expanded for several consecutive years. The primary art market is characterized by an unclear pricing mechanism and an infinite as well as limited supply. Previous business studies have so far primarily focused either on art as an investment or on the gallery?s activities. This thesis takes an explorative approach and aims to shed a light on the art collector?s behavior on the Swedish market for contemporary art.

This Master?s thesis examines different retrieval strategies used in cross-language information retrieval (CLIR). The aim was to investigate if there were any differences between baseline queries and translated queries in retrieval effectiveness; how the retrieval effectiveness was affected by query structuring and if the results differed between different languages. The languages used in this study were Swedish, English and Finnish. 30 topics from the TrecUta collection were translated into Swedish and Finnish.

There are several objects of age whose provenance and history has disappeared with time. The purpose of this thesis is to find out which analyzing methods that gives results and how the different methods can be combined and /or established in each other. The investigations centers around an embroidery, belonging to Tämta church, with unknown origin, use and age. The embroidery is long and narrow with applications in the form of dragons and eagles on a ground of velvet cloth. The dragons and eagles are covered with metal threads.

Ocean Thermal Energy Conversion, OTEC, is a sustainable energy conversion technology that is not yet commercialized. OTEC is a technology that utilizes the temperature difference in oceans between the warm surface water and the cold water at 1 000 m depth to run a Rankine Cycle. This technology can produce electricity and provide synergies like fresh water, air conditioning and aquaculture. A simulation program for three alternative OTEC systems has been created in order to decide which OTEC system is most profitable; closed, open or hybrid system. In this simulation a production cost analysis is performed in order to investigate and decide which one of the three systems that has the lowest production cost. The production cost analysis also analyzes if the profitability is affected by the size of the facility. After these analyzes, the most profitable of the three different OTEC-systems is expanded by an installation of solar collectors in order to see if the thermal efficiency is improved. The result shows that the most profitable system varies with the size of the facility.
