Plant tRNA isopentenyltransferases (tRNA-IPT, EC 2.5.1.8) have two roles, modification of tRNA and contribution to cytokinin synthesis. tRNA-IPT is among the best studied of the tRNA-modifying enzymes, but little biochemical information is available and none for the plant enzymes. Therefore two sets of experiments were conducted. The first one aimed to determine the kinetics and substrate specificity of the tRNA-IPT AtIPT2 from the higher plant Arabidopsis thaliana. The second project aimed to study the role of IPTs from the moss Physcomitrella patens in the production of cytokinin hormones.

In this study I?ve used qualitative interviews to examine four male preschool teachers? interpretations of gender and their work with gender in preschool. Specifically, I?ve been interested in what thoughts male teachers have about the preschool gender assignment, how they express these thoughts in their work, and how they perceive their role as men in preschool in relation to gender and gender equality. The teachers express that the preschool gender assignment means that one should treat girls and boys equally and give them the same opportunities.

I detta exjobb har en testplattform skapats för att kunna testa, utvärdera och jämföra olika pumpstyrningar i torr miljö. Testplattformen består av en simulerad pumpstation till vilken befintliga pumpstyrningar av valfri modell kan kopplas, det vill säga ett Hardware-In-the-Loop-system. De främsta fördelarna med en sådan plattform är flexibilitet, snabb feedback samt möjligheten att återskapa exakt samma förutsättningar för olika pumpstyrningar.Testplattformen har implementerats i LabVIEW på en PC som kommunicerar med pumpstyrningshårdvara via ett I/O-kort för analoga och digitala signaler.Det simulerade systemet konfigureras genom val av bland annat pumpar, pumpsump, inflöde och rörsystem. Utifrån de inmatade värdena och styrsignaler från pumpstyrningen simuleras sedan bland annat systemets flöden, energier och temperaturer. Nivån i sumpen, och övriga insignaler till pumpstyrningen, återkopplas från simuleringen.

This thesis treats a new perspective in the theory of classification, the context-based approach. The aim is to find out what kind of value this new approach can have in the process of creating a classification scheme for a special library collection. The first question to be answered is how the context-based approach works in a real life. The second question investigates which role the research in this particular area might have. Illustrating a real-life situation, the unit of Rättsmedicinalverket in Linköping serves as the object of study.

Ship formed monuments from the Late Bronze Age on the island of O?land, southeast Sweden, have never been thoroughly dealt with in previous research, despite the fact that the region is suggested to have had a key-role in maritime trade networks. This thesis aims to address the ship formed monuments on O?land in relationship to the monuments in northern Sma?land and the island of Gotland. My goal is to discuss how the ship symbolism was practised during the Late Bronze Age in Scandinavia from a new perspective.

The aim of this thesis is to examine how secondary teachers in the subject of history are using the textbook in their teaching. Four questions are being dealt with in this thesis. What importance is being placed on the use of history textbooks by the secondary teachers? What priorities do the secondary teachers have? How do they deal with student interests? And what is the importance of the secondary teachers? work experience? I have interviewed four secondary teachers with different work experience to complete this thesis. A Dictaphone has been used in all the interviews. Research has shown that textbooks now have a central role in teaching and the lack of alternative materials and reduction of teaching hours has made it difficult to replace. The main conclusions of the thesis are that the history textbook has a dual role depending on the teacher you ask, and that the history book is used differently by the teachers.

Syfte: Syftet med vår studie är att undersöka hur information kan hanteras med ett integrerat affärssystem till stöd för controllers och personer med ledande befattningar.Metod: Vi genomförde en fallstudie där vi intervjuade controllers och personer med ledande befattningar på WSP. Detta för att kartlägga de informationsbehov som finns utifrån deras centrala arbetsuppgifter. Med utgångspunkt från en teoretisk referensram och med vetskap om deras informationsbehov analyserade vi hur information kan hanteras med hjälp av ett integrerat affärssystem till stöd för dem.Resultat: För personer med ledande befattningar handlar det ofta om att få information för att ta sig till beslut, och de behöver oftast olika sorters information. Controllern har en central roll för att hantera och vidarebefordra information, och det är viktigt att det finns bra verktyg för att hantera och distribuera information. Ett integrerat affärssystem kan vara till stöd för hantering och spridning av information, och vid utformandet av affärssystemet är det viktigt att skapa en presentation av informationen som stimulerar användaren och ger möjlighet för användaren att förstå dess innehåll.

From autumn 2008 Sweden has reinstalled the Special Education Needs teacher education. For future special education teachers and active teachers in the field, it is important to know the history and be aware of future visions to create a good role for the Special Education Needs teachers. This study examines attitudes towards special education and Special Education Needs teachers amongst school principals and classroom teachers at seven schools in Umeå municipality. School principals were interviewed, and a survey was handed out amongst the selected General Education teachers. From this it appears that school principals have a picture of special needs education and Special Education Needs teachers' work that corresponds well with the objectives of the school's governing documents.

This paper addresses the question about what role typography plays in the interpretation of a text. From three different handbooks in typography arguments are gathered and categorized in to three categories: roman types, san serif and others. Interviews with people from the graphic design area are also a part of the paper and are accounted for in the discussion part of the paper. Areas of theory are a broad hermeneutic view based on Hans-Georg Gadamers thoughts, which have sub categories such as: Michel Foucault?s theory about discourses, John Swales genre theory and Anders Björkvall?s thoughts on typography and multi-modal texts.

Obesity is one of the biggest threats to child- and adolescent health. The amount of obese children is today increasing more in Sweden than in the US. This may in a couple of years have bad consequences for the Swedish children?s quality of life. When a child suffers from obesity it is a big stress on the body and can lead to serious consequences in adulthood.

Unlike previous research, this thesis considers the possibility of regarding the morning prayers in Swedish schools as preaching, rather than teaching. 28 morning prayers, delivered in the church of S:t Johannes in the city of Malmö during 1939-1954 by the religious teacher Astri Heimer (1889-1986), constitutes the material for analysis. The purpose of this thesis is to examine if Heimer's morning prayers may be regarded as preaching, and to discuss the significance of this, in particular considering her role as leader of morning prayers.The examination is conducted in three steps. The first step investigates how morning prayers in general ought to be understood - as teaching or preaching? This is done by describing and comparing the literary genres of religious teaching and preaching, looking into the rules and principles which define the field of application.

Purpose:  The purpose of this paper is that from the physical travel agencies perspective try to see how they perceive their future, knowing that the booking on Internet has increased.Problem: What are the prospects for future development of the physical travel agency? Has the technological development affected the physical travel agency and forced it to change its role and meaning?Method: This paper has a qualitative approach. Interviews have been made with employees on physical travel agencies to try to reach a deeper understanding and thereafter be able to give us an understanding of our problem.Conclusion: The physical travel agency has been given a new role as the employees are no longer seen as sellers but more regarded to as consultants. The travel agency has become more of an information bank than just a shop where travels are being sold. Despite this change, we believe that customers will continue to visit the physical travel agents because of the unique knowledge and services they can provide that Internet not yet can offer.
