Demonstratortest av gassensor baserad på tryckt organisk elektronik och jonledande papper
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..
Alternativ till fortsatt elektrisk generering i Olidan
In this thesis a possible cost effective runner change of some of the units in the hydroelectric power station Olidan is investigated. The possibility to drive a unit at the same efficiency point through a change of the turbine shaft speed and the rate of discharge is tested. Furthermore the theories behind model testing, determination of efficiency increase from model to prototype and efficiency measurements shall be discussed and analyzed with Olidan as a starting point.A predicted curve has been built on information from model tests and field measurements on the existing runners and runner data from the test of the new model. The predicted curve shows the difference in efficiency between an existing runner and a modern one. It is the difference in efficiency that is used in the calculations that are to show whether changing to a pair of new runners will be cost effective or not.

Gäddan & fisket i Ringsjöholm : en osteologisk metodstudie i säsong & bevarande
This paper presents the results from an osteological method study of the Ringsjöholm fishbone material. Ringsjöholm is located in Scania, southern Sweden and is 14C dated to 5960-5200 B.P. The aim of this paper is to critically analyse methods used on fish bone material in estimations of season. Three different approaches were used to estimate the fishing season at the Ringsjöholm settlement; 1) identified species, 2) size estimations of the pike based on Enghoffs (1994-95) regression formulae of os dentale, and 3) growth rings of the pike vertebrae.The identified species and the size estimations of the pike points to the fishing being active both during spring and summer. Growth rings analysis of the pike vertebrae didn?t give any quantitative results because of fragmentation.
Relational Theory of Contract och företagsförsäkringsavtal
Forming teacher teams is currently the standard way of organizing teachers in Swedish Compulsory Schools. This is the result of a process that started in the 1970s.Traditionally the culture of teaching has been one of isolation. Once the door to the classroom is shut, what happens behind the door is up to the teacher to decide. Over the past thirty years a lot of time has been dedicated to making fundamental changes in the way teachers interact with their colleagues. Today the idea of teachers forming teams is generally accepted but still the core of a Swedish teacher?s job is that of a lone worker.
Entitetkontinuitet : en religionspsykologisk tolkning
?Entity continuity? refers to recurrent transcendent experiences related to certain places (?hauntings?). The experiences are often interpreted to be due to discarnate spirits or folklore entities. Although the entity continuity experience can be regarded as religious experience, they have yet to be fully explored in science of religion.The purpose of this paper was to describe entity continuity experiences and map out the scientific discussion in order to provide a psychology of religion that provides an understanding of the phenomena. For this purpose a literature study of theories of jungian psychology, parapsychology, and described experiences was undertaken.
Adoption: professionellas och ideellt engagerades tankar kring samhällets beredskap för adoptivfamiljer
The Swedish legislation (Socialtjänstlagen, SoL 5 kap 1§ 6 st.) state that the social welfare committee is particularly responsible for those children whom are in need of support and help after an adoption or custody matter has been decided. "Adoption - but at what price?" SOU 2003:49 is a state report with the purpose to investigate different aspects around international adoptions, which brings up and discusses what supports there is for adoptive families in Sweden. With this background and a special attention towards adoptive children's health conditions when arriving to their new country we decided to study the subject adoption. By interviewing different professionals and volunteers that work with adoptive families in Sweden the aim with this study was to acknowledge how they look upon the support the Swedish community offers for adoptive parents and also how they consider the knowledge about adoption among those who in their line of work can meet adoptive children is.
Konst och exil : En undersökning av Shirin Neshats fotografi och videokonst i relation till exil
The Iranian artist Shirin Neshat has been living in self-imposed exile since the late 1970s, as she chose not to return to her home country following the ?79 Islamic Revolution. Through her works Neshat examines Iran before and after the revolution and follows political and civil transformations through strong photographs of women in her country of birth. My own use of the term exile deals with the analysis of the state of exile in relation to artistic work as a globalized and underlying motivation for art and artists. The new definition of exile is analyzed in relation with the artist?s photographs and the verbal and visual statements.

Musikteori på gymnasiet : En studie om gymnasieelevers inställning till musikteori
The transition from having been under another country?s control to becoming a democratic country can, many times, pose difficulties, which has proven itself to be quite common. Estonia and Moldova?s processes towards a democratic regime are two examples of countries with varied success in the final transition phase.When the USSR (Soviet union) fell and collapsed in 1991 Estonia was well on their way from having a communistic ruling to a democratic one due to the fact that their democratic work had already begun a few years prior to 1991. After the collapse Estonia continued with their democratic work and in 2004 the country became a EU member state.

Etiken och det heliga En studie av relationen mellan etiken och det heliga i Giorgio Agambens och Emmanuel Levinas filosofier
The first aim of this study is to discuss and try to understand the relationship between the holy andethics, and more specifically how it can be understood, which is the critical question that I haveformulated, in Giorgio Agamben?s and Emmanuel Levinas? philosophies. The second, moreconstructive aim is to discuss whether the holy can be understood as something good or problematicin relation to the society.Rooted in philosophy of religion and ethics, I have first tried to discuss how the holy has beenunderstood in the philosophy of phenomenology and in the texts of Rudolf Otto, Mircea Eliade andEspen Dahl. The holy has in the history been understood as something central in religions, and hasalso not been connected to the idea of ethics. Recently it has also been critized ? by Dahl ? for notbeing so pure as first thought of.In Levinas texts the holy has been understood as something differentiated through his distiction,in the Talmudic reading ?Desacralization and Disenchantment?, between the holy, which can beseen as something pure, and the sacred which can been seen as something impure and a form ofdegenerated holiness.
Mobil läslampa med LED-teknik
SammanfattningDenna rapport syftar till att redovisa kandidatarbetet för spåret industriell design, där målet var att utforma en mobil läslampa med lysdiodsteknik. Målgruppen för läslampan var främst studenter och resande som kan tänkas vara i behov av att läsa på platser med lite eller otillräckligt ljus. Arbetets fokus har varit att utforma ett fullständigt koncept med integrerade lösningar för strömförsörjning, kylning och en behaglig ljusmiljö.Det största problemområdet var att utforma en tunn armatur som samtidigt fungerade som en värmeledande kylfläns.

En tredimensionell modell utformades i Solid Edge och renderingar av slutkonceptet utfördes i KeyShot.Resultatet av arbetet blev en länkarmsbaserad hopfällbar läslampa i kompakt format.
Jeanne d'Arcs kanonisation : en kyrkopolitisk strategi eller skapandet av en nationell symbol
The following essay is named The canonization of Joan of Arc, a Church political strategy or the creation of a national symbol? Joan of Arc, the French heroine of the Hundred Years War, was canonized as late as 1920, in a process that began already in 1869. In the following essay I am trying to work out if this canonization is a work of the Vatican in order to gain popularity in France after the breakup with the state in 1905. The Catholic Church had, since the French Revolution, faced difficulties withstanding its position of power in the presence of the upcoming Secularism and Liberalism and their growing public support. The Catholic Church had been fighting for its members and at the same time fighting the new ideas of Socialism, Communism and Liberalism.
Hej, en kaffe, tack! : En studie om att inleda och avsluta samtal i vanliga servicesituationer
Recently, there have been intense discussions about the humanities and their role in society. Internationally, as well as in a Swedish context, the humanities have been regarded to be in a state of crisis. However, these discussions usually demonstrate a lack of historical perspectives based on thorough empirical research. The notion of a crisis needs to be historicized.In this study, a case is being examined where the relationship between science and society was renegotiated. In the context of World War II, a discourse has been identified in a borderland between science and politics through an analysis of Swedish journals and anthologies during the time period 1937-1947.
