In today?s society there is an increasing demand for renewable energy sources such as sun and wind power. These sources are intermittent, and energy storage is therefore needed to ensure a constant power supply. This report compares pumped hydro energy storage (PHES), compressed air energy storage (CAES), flywheels, batteries, super magnetic energy storage (SMES) and hydrogen energy storage.The opportunities for further development are limited for PHES and CAES in comparison with the other technologies. Lithium-ion batteries and hydrogen energy storage are considered to have the most potential in the future.

The overall objective of our research is to understand  how social workers in social services protect the individual's autonomy, integrity and a coercive law which deprives the individual of his rights.In this study, we bring out social secretaries perspective on how they see the compulsory treatment and the problems that can arise in a detention. This study is based on the questions; How are power between social worker and client? What is the social secretary of the law on compulsory as a tool to help clients?We interviewed eight social workers who work specifically with compulsory treatment. We used the result to answer our questions. As a theoretical background, we chose to use the power perspective, the concepts of flexibility and freedom of action and categorizations.The results that emerged from our study are that compulsory treatment is considered to be a positive and negative thing.

The aim of this essay is to analyze how food and meals produce and reproduce values and power relations and how these processes are portrayed in Virginia Woolf?s To the Lighthouse. Using sociological writings in the field of food consumption and production I study the structures that affect our relation to food and eating. This perspective is combined with a phenomenological view, aiming to examine how food is perceived, which is also inspired by queer theories. Using the method of close reading, the theories are applied to Woolf?s work.

The purpose of this thesis is to investigate the possibility to make small, cheap and ultra low power sensor platforms, connected in wireless networks for monitoring of home and industrial environments. The concept is based on ideas from our supervisor, Jerry Lindblom. The developed system consists of a generic platform for different sensors, a receiver and software. A GPRS module from RO Rollytech AB and a database from Gema Industri AB have been modified and used to demonstrate an example of a complete system. To the platform, it is possible to connect any resistive sensor and any sensor that can act as a switch.

Diagnosis of adhd, the cause and consequence. A study about the teachers thought about it.The purpose of this study was to examine teachers experience and views about children diagnosed with adhd, and what implication and effects it gives to the pedagogy strategies in the classroom.This is a qualitative study based on the experience of six teachers from primary school. My results have been compiled and compared to special educational research about adhd, from three different perspectives.The results showed that the teachers who have been working as teachers for a longer period, think that the problems of adhd occur primarily due to environmental causes, but then also say that they think the individual causes matters. It is also these teachers that talks very well about medication as a treatment to cure adhd symptoms. The teachers who have worked the shortest time, most of them have some special education from the teacher education.

Background:For patients with severe heart disease, may heart transplantation be the only opportunity for survival. Previous research highlights the importance of the nurse's role as supporters and knowledge brokers. People who has undergone heart transplant may be changed forever. Having to undergo a heart transplant can lead to that patients end up in a traumatic crisis. People's perception of herself and her perception of the world is also changing when the body is injured or suffers a disease.

The aim of this study is to examine ways of writing experiences of the strange and different, experiences of the other in his or her otherness and experiences of suffering. The study focuses possibilities and limits for the writing of these experiences and aims at finding a tangible way of writing literature. Part of the aim of this study is to elaborate a proposal for a way of writing experiences of the strange and different, experiences of the other in his or her otherness and experiences of suffering.    The material for the study consists of three different approaches to literature, in which theories on literature or analyses of literary works are presented. This material is initially analysed in separate analyses in which conceptions, strategies and methods for writing experiences of the strange and different, the other and suffering are identified. Secondly, the material is analysed in a comparative analysis, aimed at finding similarities and differences between the approaches but above all to let the approaches supplement and challenge each other.

The scope of this investigation is the conditions under which readings of Repulsion (1965), and its depicted mental illness, took place in Sweden during the censorship debates in 1965, and also how the reception was related to narration and subjectivity in the film. The reason for this is the strong reactions to the images of the main character?s inner state, and concerns about negative effects in the public, that were raised. One major concern is how the film articulates discourses through which meanings are produced; that is, how it works as social technology. My thesis is therefore structured around two levels; textual analysis and discourse analysis.

AbstractTitle: Dragshow on the seven seasNumber of pages: 51 (56 including enclosures)Author: Therése PlastrougiTutor: Ylva EkströmCourse: Media and Communication Studies CPeriod: Fall 2007University: Division of Media and Communication, Department of Information Science, Uppsala UniversityPurpose/Aim: My main purpose with this paper is 1) to study how film as a media can subvert traditional gender constructions and 2) study the character of Elizabeth Swann in the trilogy Pirates of the Caribbean through four dimensions; Gender performance, Class, Desire and Power.Material/Method: My main material is the trilogy Pirates of the Caribbean. I have studied Elizabeth?s character based on semiotic and narratological methods.Main results: Film as a media possesses the full potential to change traditional gender roles, but the full subversion is denied due to the heterosexual matrix. Elizabeth?s character almost completes her subversive journey throughout the trilogy, but since she too is a victim of the heterosexual matrix, a full subversion is not possible.Key words: gender performance, class, desire, power, sex/gender, subversion, narratologic, semiotic, queer, feminism, pirates of the caribbean, intersectionality, parody.

The health care system in most western countries is undergoing rapid changes with an increasing amount of people living with chronic cancer. These people have to deal with their disease in every day life together with working and family life. The relationship between health services and every day life has changed and raises new requirements. Earlier research has shown that maintaining every day life is important for cancer patients and their families. This study comprised patients with lymphoma receiving their diagnosis during 2003 ? 2005.

The foundations of the Swedish labour market have shifted due to a number of new circumstances affecting its framework. Employment is no longer a right taken for granted but rather something one should work hard to achieve. Given the new conditions, employers are not only trying to ensure their own businesses survival but also uphold the structures of our society. Competition between enterprises forces management to forge new boundaries to maintain profitability.Concerns have arisen whether or not these so called management strategies are within the limitations of the law. As a result and as a response to the design of the labour laws creativity is peaking to overrun the statutory regulations.

This report is about the experiments with mixing of the separated water and the vacuum pump seal water at Hellisheiði power plant. This is done to prevent silica scaling and clogging in pipes and reinjection wells as well as eliminating vacuum pump seal water from the plant. The experiments were done in four stages: the first stage comprised of tests with different flows of separated water at 70°C, the second stage was carried out by mixing the separated water at 70°C and the seal water with different amounts of the seal water, the third and the fourth stages were like the first and second but with the separated water at 120°C. The results show that this method is good if the mixture is around 50/50 separated water and seal water, to control the silica scaling in the separated water and to be able to reinject the seal water with the separated water. This does not eliminate the silica scaling in all of the separated water because the amount of separated water is much more than the amount of seal water that comes from the plant. .

The questions revolvearound the ideas that formed the basis for the prison library and how the prison library was organizedin practice. Three types of sources are used to answer the essay questions and illustrate its pro -blems. Firstly, annual reports concerning the swedish prison system.

The aim of this master thesis is to study electronic publishing, and our main purpose is to examine different strategies of publishing such as: markup languages and page description formats. We examine in what context these strategies are used for publishing, when it comes to scholarly documents produced by Swedish universities and university colleges during the spring of 2002. We apply a sociological perspective as the theoretical framework for to identify the main purposes for scientists to publish their work. We also discuss properties belonging to the different formats: XML, HTML, PDF and PostScript. By doing a content based survey of the websites at Borås University College and at Gothenburg University, we have found that the most common form of electronic publishing, regarding scholarly documents, are lists with bibliographical information on publications and presentations of current research.

This pilot study investigates possible treatment effects and participants' experience in an internet-based treatment of specicfic phobia. Changes in self-reported phobic fear were examined in a series of case studies and changes in attitudes towards avoidance and approach strategies were examined at group level. Seventeen DSM-IV diagnosed patients with specific phobia participated and 10 out of these completed the treatment.The results show that 80 % of the completing participants were clinically improved after the treatment and that the completing participants were significantly more negative towards avoidance strategies after the treatment. The evaluation of the disposition and user-friendliness of the treatment showed that the participants' overall view of the treatment was positive. The main advantage perceived was the flexible nature of the treatment, while the main disadvantages were the high level of motivation and discipline required from the participants.
