Detta är endast en del av ett stort arbete, på grund av omständigheterna (till exempel möjligheten att publicera en Power Point) har vi varit tvungna att begränsa vår publikation till lärarhandledningen. Det finns också en elevutgåva, Power Point-presentation samt ett prov som inte publiceras. För att ta del av dessa krävs möjlighet att komma åt Biologi C för lärares kurswebb Vt-2008 på Södertörns högskolas intranät. .

Detta arbete undersöker problematiken i att visuellt framföra och presentera ett arbetsområde i ämnet träslöjd. Uppsatsen handlar även om och hur slöjdlärare kan undvika onödig stress. Syftet med uppsatsen är att undersöka hur man i träslöjd kan utvidga sättet att presentera uppgifter för eleverna på ett inspirerande, innehållsrikt och konkret sätt. Genom att bedriva en praktisk visuell presentation i form av Power Point har jag fått en uppfattning om ett alternativ till den traditionella undervisningsformen i träslöjd. En utvärdering gjordes med eleverna efter Power Point presentationen och den visade bland annat att eleverna i år 4 fick mer utbyte av uppgiften jämfört med år 5-6.

The technological legacy from the early electrification of the Swedish railroads has resulted in a power grid with a lower grid frequency than the national power grid from which it is fed. Energy transfer between these power grids with different frequencies requires substations, adapting the grid frequency for the rail road power grid. For this purpose, a feeding power grid has been built, stretching across the country from Boden in the north to Tälle/Häggvik in the south.Power transfer in the Swedish power grid results in voltage angle differences which increase with increasing loads and transfer distance. These voltage angle differences are transferred from the power feeding substations to the rail road power grid, will in some extent cause loss of energy due to unwanted power flows from north to south.To minimize the losses due to this phenomenon, a power management system called EFS 132 kV has been developed and implemented. The system minimizes the unwanted power flows and controls the desired power flow for a good distribution of loads between the power feeding substations.This thesis investigates the extent of the transmission losses avoided due to the EFS 132 kV that coordinates the idling angles to a common reference point.The results indicate that EFS 132 kV affects the power flow, especially between the northern substations through an improved load distribution.

With background in the rapidly growing need to find solutions for sustainable energy production and the increasing interest for wind power, this report was written. With take-off point from the wind power plant Big Glenn, which has been built in the harbour of Gothenburg, a model of the adjacent power grid has been created in Simulink/SimPowerSystems. Parameters for the power grid and its components has been provided by Göteborg Energi Nät, that has also been the supplier of measurement data of produced power, the power need from loads in the vicinity, voltage levels, current values and also the variation of power factor at the wind power plant.The SimPowerSystems model has been used to perform simulations of power flow in the grid. These simulated values have then been compared to the measured values to verify the functionality of the model. Further, the model has been used to perform simulations of a grid fault, which causes a voltage drop.

This thesis examines the power of developing countries within the World Trade Organization (WTO). The research question is if there is a change in the power relations between developing countries and developed countries from the establishment of the WTO in 1995 and until mid 2006, and if so, why this change is taking place? The thesis has its theoretical starting-point within regime theory and views it from a critical theoretical perspective. A multidimensional why of dealing with the concept of power is being used to answer if there is a change in the power relations? The conclusion is that there is a small change in the power relations and that the developing countries are gaining more, but limited power.

The purpose of the essay is to discuss from the theory about the established and the Outsiders if the Culture Centre Blå Stället can serve as a meeting point between the majority of the people and the minority of the people in Gothenburg. The idea of Blå Stället is that it shall work as a house available for everyone and as a cultural meeting point between people in and outside Angered. I argue if Blå Stället really is a place where people from Gothenburg as a whole go or if there are some hindrances for their visions. My study is comprised of interviews with three of the staff at Blå Stället. With the theory about the established and the outsiders I want to show that the division in the city between ?them? and ?us? has to do with differences of power.

The objective of this study was to investigate how power relationships between journalists and politicians were shown in the fictional BBC tv-series ?The Hour?. We wanted to investigate how these power structures is narrated by the producers of the series and what impact the narration could have to the audiance of the 21th century.We choose to analyse a total of 12 scenes from all of the six episodes, which are all set in Britain during the beginning of the Suez Canal crisis in the 1950?s, all seen from a BBC editorial point of view.In our analysis we chose to use two different kind of methods, the first one was a situation analysis and the second one a text analysis. The situation method was useful to get a perception of the relations between the participants .The text analysis we used to analyse what was said in the tv-series and to interpret underlying motives.The fictional form necessitated a personalization of power structures, in the sense that each and every power was represented by a single character; political power was for instance represented by the character of Angus McCain.

The aim of this paper is to get a deeper understanding if research about international relations has any practical meaning. The main focal point is about the importance of the scholar idea soft power, and its meaning on foreign policy actions through expressions. A quantity and quality method is used. The point of the main theory that concerns international relations takes a rationalistic perspective, and expands it to the notion that ides can have an impact on policy outcomes. Three different types of research utilization can be traced to determine in which way an idea is getting implemented.

We have studied how power is portrayed in Swedish journals by analyzing eight portraits of Swedish persons with economic or political power. We have studied how they and their power are described by the journalist in text and picture. We wanted to see which picture the journalist shows of people with power, what properties they are given by the journalist and how this picture is shown by the texts and the pictures. We have also looked if there are any differences between people with political power and people with economic power. We have under our studies noticed that the persons with power are described as very successful and special and this picture are shown in a very clear and unproblematic way..

This essay is about power in the classroom. It is about the power dimension of the student-teacher relationships that arise in that space. The overall aim has been to investigate which categories are fruitful in a power analysis of these relationships. My aim has therefore been to develop power categories and to use them to identify and to categorise cases of power interaction that take place between those particular actors in that particular setting.In order to gather material for my study I have both read literature that approaches the study of the student-teacher relationships from a power perspective and done a series of observations in a high school.My theoretical frame comprises a concept of power and a series of power categories. These categories include strength, authority, inducement, coercion, violence, resistance as well as to possess power, to have power, to exert power, the scope of power and the base of power.

The aim of this report was to investigate if Sweden can have 100 % renewable electricity production in the year 2050. The conclusion is that it is possible but under certain conditions. For instance wave power must be in commercial use. When wind power and solar power represent a large percentage of the electric production there will be a lack of electric power during the winter but during the summer there will be a surplus of electric power. Both the surplus and the lack of electric power need to be taken into account.

Undersökningen gick ut på att undersöka om historiska berättelser är en relevant undervisningsmetod för att öka elevers historiemedvetande och fördjupa deras kunskaper. Kunskaper ansågs i detta fall vara fördjupad förståelse och empati samt faktakunskaper. Även elevers och lärares syn på undervisningsmetoden undersöktes. Undersökning skedde på en mindre skola i nordvästra Skåne i två niondeklasser. En berättelse och en Power Point konstruerades och den ena klassen fick lyssna till berättelsen och den andra till Power Point undervisning.

Wind power is becoming an increasingly important source of energy. There are several national and international goals set to increase to amount of renewable energy, and in order to meet these goals, the wind power production plays an important part and the establishment of new wind power farms are required. The Swedish national project Riksintresse Vindbruk has appointed areas in Sweden suitable for wind power, mainly when looking at the physical wind conditions of the area. In this study, I aim to define suitable areas for wind power establishment in Norrbottens län. In order to reach this goal, a critical regional method was developed and completed using GIS.
