Svenska och utomhuspedagogik i lågstadiet : -Vi går ut för att lära in
AbstractThe comprehensive purpose of this essay is to get deeper insight, and more knowledge of how it is possible as an educationalist to integrate Swedish with outdoor education at a junior level. Children learn to read in different ways. In order to improve their reading and writing it is important to be open for alternative ways. In my survey I have chosen to interview three active educationalists. The method I selected was quality interviews.
Sverige-Norge unionen : Hur ämnet förmedlas i svenska respektive norska läroböcker i grundskolan
It is the curriculum and the syllabus for history that decides what the classbooks will include. The intention with this paper was to found out what Swedish and Norwegian classbooks writes about the union between Norway and Sweden in 1814-1905. The result has been compiled from a study with teaching materials. Two Norwegian and two Swedish books which was written for the elementary school was used in the study. The text in these books has been analysed from a number of questions.
Vad är ?rätt? gjutkvalitet? Hur uppnås det?
Ever since ABB has begun diecasting their rotors instead of permanent mold casting it,variation in the quality of the cast has arisen. Diecasting is performed in three differentmachines, M1, M2, M3 with 400, 660 respectively 800 tons of die locking pressures.The aim of this thesis is to answer the following questions:What is the ?right? cast quality? How is the right quality achieved?For sizes 160-180 solutions will be proposed that consider eccentricity between thelaminate and the short circuit ring as well as elimination of the thin Al film that appearson the outer periphery of the rotors.Through considering the statistic material the most often diverging rotor type has beenidentified and one of the actual rotors has been sent to a laboratory to be analyzed inorder to establish the current defects. The result of the analysis shows that there areplenty of gas- and oxide-porosity.It has been proved that every time the dies temperature decreased below 120°C thecontent of gas porosity increased. It is due to rapid solidification of metal that flowsthrough the ?cold? laminate.It has confirmed that enhanced porosity in squirrel cage causes high impedance in therotors.
Djurförsök och försöksdjur förr och nu : gymnasieelevers tankar och värderingar
Den här uppsatsen är baserad på en enkätundersökning samt intervjuer med gymnasielever angående deras tankar kring djurförsök. Jag har intervjuat studenter från två olika naturbruksgymnasier. Båda har inriktningen djurvård men det är endast en av dem som ger en specialiseringskurs inom forskningsdjur.Min frågeställning är att undersöka om elever som läser kursen i försöksdjurskunskap har en annan inställning än de elever som endast läser djursjukvård. Som resultaten visar så är de eleverna som läser specialiseringskursen mer positiva till både djurförsök och att jobba med försöksdjur. De har också en mer korrekt bild och större vetskap om hur verkligheten ser ut för försöksdjuren.

Avskiljning av uran från dricksvatten med reaktiva filter :
Water is our most important provision and its quality is above all dependent on the
geological conditions in the area from where it is extracted. Due to geological
properties there are certain areas with an elevated risk of high uranium levels in the
ground water, which in turn constitutes a risk for human health. Consumption of water
that contains a high concentration of uranium implies a health risk due to the chemical
characteristics of uranium. Livsmedelsverket (The National Food Administration) and
Socialstyrelsen (The National Board of Health and Welfare) therefore recommend that
precautionary measures should be taken when the uranium concentration in ground
water exceeds 15 micrograms per litre. In particular, drinking water collected from
wells in areas with uranium-rich bedrock may have a harmfully high level of uranium.
One of the wells of the Ärla water purification plant, located near Eskilstuna, Sweden,
contains water that exceeds the guideline of 15 micrograms per litre.
One interesting technique for removing uranium from drinking water is adsorption to
reactive filter materials.
Utveckling av förpackningssystem för torra insatsvaror i livsmedel
This project includes development of new packaging for dry spices and an investigation of how to automate the production line. The preliminary investigations show needs of an environmental friendly packaging possible to re-close. After screening for suitable materials three concepts were developed, a stand-up pouch, a plastic jar and a metal can. The pouch was excluded in a concept choosing process. In this process it was also decided to further develop the metal can concept.
Den stygga trädgården : En sinnlig tolkningsansats med utgångspunkt i Helen Chadwicks Cacao och Bad Blooms
The purpose of this essay is to discuss what a sensual interpretation of art is and what it should include. The discussion is based on an attempt to do a sensual interpretation of the Greek-British artist Helen Chadwick?s Cacao and Wreaths to Pleasure. Chadwick was an artist working with well-known materials in new and unexpected ways. An interpretation of her works should include the fact that her art affect us on different levels, both intellectually and sensually.
Watashi wo aishite ? älska mig : En lacaninspirerad läsning av Haruki Murakamis Sputnik Sweetheart
A rhetorical analysis of the educational interactive film ?Riskprofilen?, produced by the Swedish Civil Contingencies Agency (Swedish: Myndigheten för Samhällsskydd och Beredskap). This essay uses the theories and methods of Procedural Rhetoric, as described by Professor Ian Bogost, and Visual Rhetoric, as described by Professor Brigitte Mral to analyse the interactive and visual component parts of the artefact, and compares them to the intended purposes of the artefact as stated by documents pertaining to its creation, found to be those of educating the public; marketing the agency; and driving traffic to its webpage. The artefact is through analysis found to fulfil the purposes of marketing the Agency and of likely increasing traffic to the website upon which it is hosted. Regarding the primary, educational purpose this analysis finds that the artefact does not teach a user the accident-avoidance strategies it claims to do, but is dependent upon further materials..
Ekologisk gestaltning : en utvärdering av hur landskapsarkitektur påverkas av ett ekologiskt förhållningssätt
This paper examines and compares several different sites in Sweden in addition to one in Mexico regarding whether the ecological requirements theses sites have had during planning and construction has affected the design in any way. Is it possible that, for different reasons, one thinks ?like nature? when one thinks of ecology and, if true, how does this reflect on the spatial and structural design? This paper tries to identify if some sort of general design expression is used in projects with requirements on ecological sustainability. In total, five projects have been compared in different areas such as choice of materials and their composition.
These projects have an ecologically sustainable processing of water in common, although most also have ecological consideration in other areas as well.

SJ- OCH TJ-LJUDENS STAVNING : En empirisk undersökning bland andraspråksinlärare på SFI- och SVA-nivå
This paper investigates the presentation of Islam in textbooks used in the study of religion in high schools. The papers focus on two main questions concerning the ways in which Islam is presented in the analysed textbooks, and how the new curriculum has influenced the portrayal of Islam in the materials. Here, the paper utilizes a method of critical discourse analysis with Faircloughs three-dimensional analysis. The paper then concludes that the presentation of Islam is negative in nature, with the content and view of Islam having been simplified and stereotyped. Often the textbooks studied frame Islam as being an aggressive and oppressive religion, especially in matters con-cerning women.

Pedagogisk dokumentation i ett förändringsarbete
The main objective of this study was to find out what pedagogical documentation does and to get knowledge of what you may need to consider in order starting a process of change with a focus on pedagogical documentation. To get answers to my questions, the study is based on pedagogical theories from scientists and interviews with three preschool teachers who have different experience on documentation. My main questions were: What characterizes a pedagogical documentation? What tools / materials do I need to do a pedagogical documentation? What is important to consider when starting the process of change with pedagogical documentation? The result shows that pedagogical documentation is an approach that is based on that one is curious, interested, observant, listens, talking and researching with children and colleagues. You give the kids great participation which you can then pick up the children's learning processes and reveals that the business and the children develop according to curriculum objectives.
NEDKYLNING HOS VANLIG B?NA, PHASEOLUS VULGARIS
Beans are a global source of plant-based protein, and in some countries, they constitute a primary source of protein intake. With ongoing climate change, including rising temperatures, it is necessary to adapt beans to ensure a reliable food supply. An important mechanism that many plants have, to cope with high temperatures, is cooling through transpiration. During transpiration, stomata open and release water vapor. Water molecules use heat energy from the leaf to convert into gas, thereby cooling the leaf.
