Elevanpassad undervisning : En studie om gymnasieelevernas perspektiv på lärande i naturvetenskapliga ämnen
The purpose of my study is to determine students? attitudes to the Natural Science subject. I want to contribute to scientific discourse about different learning styles that can respond to childrens? requirements in teaching as well as to determine the student?s experience of learning styles. The studies were carried out at an upper secondary school in Stockholm (spring term 2011) for three different classes.
Green structure planning in Transit-oriented Development (TOD) : a spatial analysis of Önnestad
During the winter 2011 Isaksson and Andersson did a time budget study on Nordens Ark?s Przewalskis horses during daytime when there were visitors and caretakers in the park. This time budget study was made during daytime and when there were no visitors or caretakers in the park. The horses where observed in the morning (5.30-6.30 am) and in the evening (5.45-6.45 pm) during four days. In addition to a time budget, the horses? positions in the enclosure were registered.
Klimat & Patriarkat : Genusgeografi i Huddinge
The essay deals with gender aspects on climate change adaption. The aspects consist of the fact that women in Sweden drive cars less than men, and that women in the developing world are more affected by natural disasters arising from global warming. This study was carried out in the municipality of Huddinge, a suburb to Stockholm, by interviewing one Agenda 21 coordinator, one planner and one student in genderstudies. I also attended a meeting in the Committee for built environment in the Huddinge Municipality, to ask the politicians questions and observe gender structures during the meeting. The results also consist of a search for gender-related words in the documents used in the essay.The results are analysed using ecofeminsim, a theory that connects woman subordination and environmental destruction.
Förskolekulturens möte med det mångkulturella samhället : ett möte mellan pedagogen och föräldrarna
My main question in this essay has been: why does the preschool advocate being outdoors? How should we respond to parents who have a different view on this? Children's right to participation and influence is also a question that I raise. How should we preschool teachers do when we stand between the child's desire to be out and the parents wish that their child should be indoors? By reading what is written in the preschool curriculum on children's influence, I have come to the conclusion that we preschool teachers must listen to what the children express that they wish to do, otherwise we go against our policy documents.My dilemma is about how to respond to parents who have a different opinion on being outdoors than we have. Many parents express an aversionagainst their children having to be outdoors.
Integration av ämnesinnehållen i ett temainriktat arbetssätt : Lärares åsikter gällande integration av matematik och naturorienterande ämnesinnehåll i förskolans temainriktade arbetssätt
Recently I discovered that preschool education has evolved from integration of various subject contents and working methods. The purpose of my study is to investigate preschool teachers' attitudes and ways of working with a theme-oriented approach. I also want to examine their opinions regarding the integration of subject content in terms of mathematics and science subjects (NO) in preschools theme-oriented work approach.My questions for this study are:What is a preschool teacher's attitude and their ways of working to a thematic-oriented approach?What is a preschool teacher's opinions regarding the integration of subject content, especially in mathematics and science subjects (NO) in their pre-schools theme-oriented work approach?I have used myself a qualitative method of investigation to produce materials for my research project. I collected my empirical material for my study from the semi-structured interviews that was done with four preschool teachers in two preschools in Botkyrka municipality.
Lantbruket som energiproducent : tekniska, ekonomiska och miljömässiga förutsättningar för fjärrvärmeproduktion med lokalt skogsbränsle
A third party access to district heating networks has been proposed in Sweden, to increase the competition
on the district heating market. Such third party access could create opportunities for the agricultural sector
as an energy producer. This study describes the technical, economical and environmental prerequisites for a farmer cluster to build and run a heating plant, fueled with local wood fuel.
The heating plant in the described scenario is 8 MW and will supply a village of 1000 houses, and is fueled with wood chips exclusively. Supplying a heating plant with fuel puts high demands on the logistics, since there need to be a continuous flow of fuel. In the scenario, wood residues from felling and thinning is stored in stacks in the forest, and a few times a year chipped and transported to a storage area at the heating plant.
In the study, an estimation of the profitability has been made by estimating the cost of the investment,
personnel, operating and maintenance costs and costs for the fuel and ash handling.
FRISTADS ? Supply Chains, från tråd till arbetsbyxa
The Swedish Textile industry has since the beginning of the 70-ties moved their production to countries with cheap labour further and further away. The production in the Baltic countries and Asia has become reality for many Swedish manufacturing companies. With today?s technology the communication with remote countries has ceased to be a problem. The difficulties have instead turned out to be more focused on transportation of goods and just in time deliveries to Sweden.
Kompatibilitet med BIM-koncept : Revit Structure 2012 och Robot Structural Analysis 2012
This thesis deals with the compatibility between analysis software Revit Structure2012 and Robot Structural Analysis 2012. The purpose is to become more aware ofinformation management models to be compatible across different softwareapplications. The structural model is made to be optimal for the compatibility of othersoftware Aim is also to gain an understanding of the transferring methods that exist,and which method is most convenient to use and to examine whether the methodswork in practice. Objective of this project is to make the modeling processtime-efficient for constructors. Models do not need to be structured in severaloccasions in different software; it only needs an optimal model that transfers properlybetween software.The method used in the thesis consist cases where the transferring process isexamined.
Användande av diffusionsspärr vid tilläggsisolering av äldre byggnader med trästomme
In the current situation a big part ofthe settlements that exist in Sweden isin need of renovation and energyefficiency in order to survive.Therefore, also many of the older houseswith a wooden structure are in a need ofenergy efficiency, which can be done ina variety of ways, including addinginsulation.This project deals with whether the useof a diffusion barrier or a vaporbarrier affects a wall structure byadding insulation to an older house witha timber frame. The insulation materialswhich are concidered in thisinvestigation are mineral wool and woodfiber insulation. Efforts are focused onthe effects of moisture on theseinsulation materials.To demonstrate the differences thatarise the moisture measurement programWUFI have been used to simulate avariety of wall designs. These designsare developed in consultation with theconstruction carers who are active inthe industry.Using WUFI graphs illustrating themoisture levels of the wall structureswere obtained and from these conclusionsvould be drawn. The work demonstratesthe differences that arise when using adiffusion barrier or vapor barrier inwall construction.
Föryngringsresultat och beräknad virkesproduktion i naturligt föryngrade tallbestånd i Västerbotten under mitten av 1990-talet :
According to the Board of Forestry, in Västerbotten, many natural regenerations of Scots pine (Pinus sylvestris) carried out on privately owned forest in the middle of 1990 in Västerbotten have rendered a bad regeneration outcome and will provide a low future forest production. The Board of Forestry believes that the negative result can be explained by the fact that the regeneration has been carried out in wrong locations and that scarification failed to work as planned. In order for an accepted rate of regeneration the guidelines of the Forrest Act require, not less than 10 years after final cutting at natural regeneration, that there should be at least 1300 (site indices 16 m) - 1700 (site indices 20 m) main crop stems per hectare. Main crop stems are defined as stems according to the place of growth and appropriate tree type, in addition with regard to quality, stage of development and damage risk have a prospect of succeeding. In addition main crop stems should be separated by surface so that the proportion sample plots with 3 meters radius, and lack main crop stems, are not more than 10 % of site indices 14 meters or higher.
Styr genus valet av Cover Story? : En fortsatt studie på projektet Cover Story, där genusaspekten kommer upp till ytan på ett intressant sätt.
Cover Story is a project, which students at Lillholms - and Ekholms School worked in during spring and fall of 2009. Several school subjects were integrated in project; social studies, art and Swedish, to empower the students to create, implement and design a magazine. The purpose of the project was to give the students the opportunity to fantasize about the future and their dreams by creating their very own Cover Story. During the project I realized that the student?s selection of magazine genre had a direct relation to the gender of the students themselves.
3D-skrivarens intåg i immaterialrätten : - Om 3D-bilder, 49 § URL och vikten av lämpliga avtalslicenser
The current study aimed to test the public self-consciousness impact on creative performance. An experimental design was used in which 40 participants were randomly assigned to two groups, one of which was the experimental group and the other was the control group. A mirror was used in the experimental group to induce public self-consciousness among the participants while they performed creativity tests. A consequence test was used where the participant had to give suggestions for the given scenario "What would happen if everyone became blind?" which was then measured in the number of proposals (fluency).
Vätedriven förbränningsmotor : Klarläggande av framtida hållbarhet
Today when new and harder demands on CO2 emissions are developed, vehicle manufacturers must work to develop new engine solutions to new kinds of fuels to replace fossil fuels. A fuel that could be applied is hydrogen. When hydrogen is combusted only water vapor occurs. Hydrogen is known to be explosive and flammable. These properties are both good and bad for combustion.

Miljöpåverkansbedömning vid tillverkning av etanol från cellulosabaserade råvaror : ekologisk gård självförsörjande med drivmedel
Fuel produced from renewable resources is of big interest. In this project the difference between a few different renewable materials are compared on the matter of environmental load when ethanol is produced. The renewable materials that are compared are Salix, straw and reed canary-grass (rörflen). The cellulose in the material is cut down to small pieces and then hydrolysed so that the sugar from the cellulose can be fermented into ethanol.
Tha amount of ethanols that is studied in this work is the smount of ethanol needed to cultivate 1000 ha. The functional unit in the report is 1000 ha.
