NTA i förskola : En studie i hur förskollärare upplever att arbeta med NTA
AbstractThis study deals with NTA in preschool and the purpose of the study is to find out how the NTA project works out in practice. In the empirical study I have used questionnaires as a research method (Trost2001). Questionnaires have been sent to preschool teachers in the whole of Sweden to get as good a selection as possible. The responses received have been processed and analyzed. The results are reported below.The majority of the teachers thought it worked well to work with the NTA.
Ambulanspersonals uppfattning om fysiska tester och fysisk träning inom ambulanssjukvården
There is no standardized test to control the appropriate physical ability in the Swedish ambulance service. The county in question does not perform annual physical tests. A project has been going to develop science-based physical tests, designed for the ambulance service. The research has resulted in the Aasa-test.Objective: The aims of this study were to examine the ambulance staff perception of the Aasa-test relevance, introduction of annual tests and the importance of their own physical training in relation to ambulance work.Method: A quasi-experimental study with a comparative design has been conducted. Aasa-tests were conducted in 41 randomly selected staff at an ambulance station in central Sweden.
Fisk- och fågelpredations påverkan på den bentiska makroevertebratfaunans sammansättning under tidig vår i Tåkern
Predation is one of many factors that form the structure of the macroinvertebrate community in lakes, wetlands and watercourses. Earlier studies lack an examination concerning how fish- and waterfowl predation affect macroinvertebrates during shorter periods in the spring. I performed an exclosure study in the shallow eutrophic Lake Tåkern which is located in the western part of Östergötland County, Sweden. The experiment was performed during a three week period (1-21 April 2012) when the water temperature was low and the density of migrating diving ducks was high. The experimental cages used included three out of four different treatments; general predation (open cages), bird exclusion (net with mesh size 90*45mm) and no predation (net with mesh size 1*1mm).
Doktorander i fysik söker information : en intervjuundersökning av forskarens första tid som informationssökare
The aim of this Master's thesis is to examine difficulties concerning information acquisition, use, and management experienced by graduate students in Physics during their first years of research work. Semi-structured, qualitative interviews were carried out with nine doctoral students. The theoretical background for analysis of the material is based on the work of Patrick Wilson, with particular focus on the concept of cognitive authority, and on that of Lars Seldén, who has proposed the idea of an information seeking career running parallel to the academic career of the researcher. Results from the interviews indicate that most of the students, in the early stages of their information seeking careers, rely to a great extent on supervisors and more experienced colleagues when identifying material needed for the research project. In a situation where information of potential relevance is abundant and where experience and focus are not yet fully developed, senior researchers function as cognitive authorities and as guides to other cognitive authorities.
Paul Tillich och Verkligheten : Är Bibelberättelserna "bara" symboler
In this essay I have aimed to examine how the theology of Paul Tillich relate to modern views of reality, both the way it was expressed in his contemporary time and the way I see it today. Reality I have defined as an entirety of the physic- and metaphysic reality. A so called panentism where God is reality and the world is a part of this reality.With Tillichs Systematic Theology as my principal material, I have first made a brief presentation of his theology, of its construction and main concepts. Then I have chosen to further examine the way he describes being, reason and revelation to see how this particular concepts of Tillich agree with my definition of reality. In this I have consulted the books Tillich in Dialogue by Mackenzie-Brown and Natural Theology Versus Theology of Nature, a book edited after the forth international Tillich symposium 1992, which had "Tillichs thinking as impetus for a discourse among theology, philosophy and natural sciences" as a theme.I have tried to point out the possibilities opened up by the ontology and epistemology of Tillich for the dialogue between theology and natural sciences.

Lärande och Utomhuspedagogik i Fysik på högstadiet (Learning and Outdoor Education in Physics at high school)
Skolverket redogör i Läroplan för grundskolan, förskoleklassen och fritidshemmet 2011
för att undervisning i skolan ska innehålla olika arbetsformer och varierande arbetssätt
för eleverna att nå samma mål. Ett sätt att variera klassrumsundervisning är genom
utomhuspedagogik. Utomhuspedagogik är ett komplement till traditionell undervisning
och handlar om att undervisning och lärande sker genom upplevelser i utemiljön.
Utomhuspedagogik kräver ett växelspel mellan teori, upplevelse och reflektion. Syftet
med denna studie var att utreda huruvida utomhuspedagogik i fysikundervisningen på
högstadiet var ett väl motiverat sätt att variera undervisningen, med avseende på hur
elever påverkas av utomhuspedagogik utifrån ett såväl lärar- som elevperspektiv. För
studien utfördes semistrukturerade intervjuer med två lärare och sex elever från två
olika skolor i Skåne.
Individuation : Ontogenes : Prolegomena till Gilbert Simondons genetiska ontologi
The following text constitutes an attempt to present the French philosopher Gilbert Simondon's genetic ontology through an account of his reconfiguration of the problem of individuation in his doctoral thesis from 1958, L'individuation à la lumière des notions de forme, information, potentiel, métastabilité. The intention is to show how Simondon through this reconfiguration of a classical philosophical problem ? in which concepts and schemas from contemporary Physics and technology is utilised in a critique of the bi-polar hylomorphic schema as its traditional, substantialistic solution ? becomes able to articulate an anti-substantialistic and anti-reductionistic ontogenesis as first philosophy. A systematic philosophical conception that according to Simondon precedes every critical investigation of the subject as well as every scientific ontology ? not by establishing a pre-critical position, but by exceeding Kant's critical position: that is, through a displacement toward a conception of the transcendental conditions for the genesis of being and thought as real conditions, rather than conditions of mere possibility.
Undersökning av förskolan Temmelburken certifierad enligt Miljöbyggnad : Termiskt klimat, energianvändning och höjning av certifieringsnivån
WSP building Physics in Stockholm has certified the preschool Temmelburken in Bromma with the system of certification Miljöbyggnad. The rating of the building became BRONZE. In this thesis the preschool has been investigated with respect to the three areas: thermal climate, use of energy and improving of the level of certification. The thermal climate at the preschool has been investigated by a questionnaire survey and by measurements in order to do comparisons between the results from the two investigations as well as with the results of the simulations that WSP has done at the certification of the preschool. The differences between the results from the simulations and the questionnaire survey for winter as well as from the measurement performed with a comfort meter the 19th of March are concidered to be reasonably small since they give rise to the same rating according to Miljöbyggnad. Operational data for the use of energy for the preschool have been obtained in order to do comparisons with simulations performed by WSP and Svenska Besiktningar AB. The comparison shows that the simulated values for the specific use of energy are lower than what the real specific use of energy would be for the preschool, since just the operational data for the heat energy is higher than the simulated values. At the investigation of the possibility of improving the level of certification it was found that the rating of the preschool can be raised from BRONZE to SILVER by improving the ratings of the ?thermal climate summer? and the ?daylight?.
Grafisk utvecklingsplattform för signalbehandling - Design och implementation
We have different kinds of signal processing everywhere around us in our everyday life, in our cellphones, when we are listening to music, watching TV etc. This makes signal processing a very interesting and important technical area, where the demand of skilled engineers sets the limit of what is possible.Working with signal processing requires in-depth knowledge in areas such as mathematics, Physics, electronics, and other related areas. For this, it has traditionally been demanded by a talented developer to also master the advanced programming languages such as C / C + + and Assembler.This has begun to change; today there are several companies that offer graphical development environments for signal processing, environments where programming skills are not needed anymore, and the focus can be on signal processing instead.The goal with this project is to build a corresponding graphical development environment to reach an understanding of what is required of these systems, and also to grasp what opportunities that are available within graphic programming. Inspiration for the work has partly arise from some of the tools available on the market, and partly from previous theses that have been written about graphic programming.The challenge lies in creating a program that can execute signal diagrams in real time from given signal blocks, and be able to handle feedback loops in an efficient way and to do so at the lowest "cost" in terms of clock cycles as possible. This should also be compared against to code, compile and run a complete signal diagram directly.To increase the usability it should also be possibility to externally manage in real time the parameters of the signal diagram during execution.The interface is a separate program, which is to some extent similar to Matlab Simulink, where a signal diagram is drawn up graphically by connecting wires between different signal blocks.
Dämpning av ljud i Shift-by-Wire växelväljare : Noise damping in a Shift-by-Wire gear shifter
Constantly growing demands from the costumers in the Automotive industry forces the subcontractors to seek alternative ways to compete. One parameter of quality is the components tolerance against NVH(Noise, Vibraion & Harshness) aspects. Kongsbergs Automotive has developed a new gear shifter platform (Shift-by-Wire) that is sold to Alfa Romeo and used in of their car models. However, the company is not pleased with the components sound quality, therefore the main purpose of this thesis is to develope a number of concepts that is supposed to enhance these NVH-aspects.To get an understanding of the problem an analysis of the causes of the emitted sound has been done parallell to a product decomposition, function decomposition and a Ishikawa-diagram. Together with these methods has a litterature study been performed to get familiar with the Physics of an impact and especially the emittment of noise.
Ett rikare lärande med variationsteorin som vägledande princip!? : En Learning study om det vita ljuset och dess färgspektrum.
Utifrån arbetsmodellen Learning study, med variationsteorin som utgångspunkt har forskning genomförts i två klasser i Sverige med syftet att försöka identifiera kritiska aspekterna för elever i årskurs nio inom ämnesområdet det vita ljuset och dess färgspektrum. Studien är en vidareutveckling av en tidigare genomförd studie i Hong Kong och har därför även haft till syfte att undersöka om de identifierade kritiska aspekterna är generaliserbara från en skolkontext till en annan kontext.Den svenska skolan styrs nationellt utifrån styrdokument, skollag, läroplan och kursplan för skolämnet och läraren har även riktlinjer för att få en yrkesetisk förankring. Dessa delar är viktiga att läraren tar i beaktning inför planering av undervisningen. Elevernas bakgrund och förkunskaper i ämnet är av stor vikt för läraren att ta hänsyn till för att de ska kunna ta till sig undervisningen om det som läraren har tänkt att de ska lära sig.I denna studie kunde åtta kritiska aspekter identifieras i de två klasser som undersökningen genomfördes i. Fem av de kritiska aspekterna var redan identifierade i Hong Kong.
Energihushållning och varsamhet för äldre byggnader : Chefsbostaden i Strömsholm, ett timmerhus från 1900-talets början
This report is the result of a degree project in building engineering, at an advanced level. The project evaluated a building from a technical and historical point of view, and focused on its energy consumption, particularly the energy used for heating. The building in question was a small apartment building in Strömsholm, Sweden. It was made in 1902, from vertical logs, a not so common form of the traditional log house. The goal of the project was to evaluate if the energy consumption could be reduced in accordance with building preservation regulations, that is without damaging any of the building?s cultural or historical values.The building was surveyed with the help of archive and literature studies, interviews and inspections.
Utveckling av metod för retrospektiv bestämning av absorberad dos i korall medelst elektronspinnresonans
This diploma work was performed at the department for radiation Physics at the Health University in Linköping. Its aim was to develop a method to retrospectively quantify the absorbed dose in coral. Coral is a material which suites well as a retrospective dosimeter because when exposed to radioactivity its induced free radicals are stable in time. The number of radicals is proportional to the accumulated dose so the dose can be calculated by quantifying the radicals. Therefore, coral can tell us something about the past environment and also be used in dating purposes.A young, modern coral from the Red Sea was studied and also a fossil one which I was given from the Natural History Museum in Stockholm.
