"Det var inte mitt val" - en narrativ studie om upplevelser av elektrokonvulsiv terapi (ECT)
This study aims to highlight patients´ experiences about and thoughts of side effects fromelectroconvulsive therapy (ECT), a therapeutic method commonly used when having severedepressions. The framing of questions were how the respondents of this study describe theirlife before, during and after ECT-treatment, how the treatment has affected their daily life andhow these experiences may contribute to the awareness of power in professional relations.The study is based on three semi-structured narrative interviews and the main result showedthat, according to my interpretation, ECT as a treatment obliterated memories, quality of lifeand daily structure for all participants. Unfortunately they have all become subjects ofpsychiatric power and have faced considerable difficulty in getting professional recognitionaccording to their severe memory issues. The respondents have lost the ability to relate totheir past which clearly makes them struggle in their present context. A point in commonamong them is that neither of them wanted ECT but, because of the lack of communicationbetween them as patients and the health care in general, they all ended up getting it..
Hur mikrofinanser genererar empowerment hos kvinnor i utvecklingsländer : Pengar med ett syfte
Social work as an traditional aid is an area that provides welfare services financed from public funds, which is one of the methods of microloans. Microloans have since the mid-1970s has become an increasingly common tool in the fight against poverty. Instead of purely assistance is now offered microloans from more banks and other institutions, as well as NGOs (non governmental organization). This paper aims to study whether and how microcredit can contribute to the empowerment of women in Bangladesh and India. This study is based on a qualitative text analysis, and has hence been based on a number of reports and articles. The paper examines, from a radical feminist perspective how microcredit can fight and eliminate poverty, and how empowerment can help women in developing countries to become independent and liberated. The introduction of micro-loan is considered to have positive effects on women's empowerment in the short term. But it is, however, the longer term effects that are considered to have the greatest positive impact on society's unequal structures.
Reglering av turbins ledskenor i vattenkraftverkmed hjälp av elektriska ställdon
Hydropower is the largest renewable energy source available in today's society. Operation and production is handled by high-tech electronics. This thesis is done on behalf of Statkraft Sweden AB who wants to explore the possibility of replacing the hydraulic cylinder with an electric actuator, generally as well as a case of a small power station on the river Nissan. Whether it is the chaplain or francis turbine vanes are actuated by hydraulic cylinders. Because of Gustavsberg hydropower is inconstant operation, this report is based on power calculations, which are read and computed according to the available hydraulic diagram.
Musikskolecheck. En undersökning om den nya musikskolechecken i Nacka kommun
AbstractThe future of ethanol is depending on good solutions for the production. ENA energy power plant produces electrical power and district heating by heating biofuel. By building an integrated bioenergy plant surplus steam could be used to produce ethanol as fuel to vehicle.This would mean that ethanol is produced renewable energy and the energy for the process derives from the surplus of power. ENA energy, MDH (the University of Mälardalen) and the energy authority has initiated a research project were different bioenergy combinations integrate with existing power plant. As a part of the project which size an integrated factory should be to gain the best efficiency for the plant was investigated. Consideration will be taken to the cost of the production in order to be competitive to the price of imported ethanol. Etanolens framtid vilar på bra lösningar för framställning. I ENA energi kraftverk i Enköping produceras el och fjärrvärme genom eldning av biobränsle. Genom att bygga ett integrerat bioenergikraftverk där skulle man kunna använda överskottsånga till att framställa etanol som fordonsbränsle.
Utredning av frekvensregleringens påverkan på mekanisk utrustning i en kaplanturbin
As a consequence of increasing wind power installations in the Nordic grid the last years, the need for regulating power has become larger. In the Nordic grid, regulating power is mainly provided by hydro power. One part of the regulating power is called frequency control, which ensures that the grid frequency is stable and close to 50 Hz.However, setting the turbine into frequency controlled operation may cause stress and wear of the components in the mechanical control system. Frequency controlling implies large and frequent servo forces and longer travelling distance of the sliding bearings in the Kaplan turbine.Based on one selected Kaplan turbine, Selsfors G1, measurements and MATLAB calculations have been performed in order to determine forces and movements of the linkage system. With these forces and movements as input, stresses and fatigue have been determined as well as sliding distances, bearing pressures and wear of bearings during a typical lifetime of 40 years.The results indicate that no severe wear exists on the bearings during 40 years of service.
Modellera i 3D med Tekla Structures. Ett konstruktionsprogram anpassat för BIM
On a request from the water sewage plant Gryaab in Gothenburg a power quality survey wasperformed. The voltages and currents have continuously been sampled in the incoming 10 kVsubstation HSP01 from April-August 2008. Power quality measurements were also performedin Gryaabs other 10 kV substation HSP04 fed from HSP01 and at the terminals of theinduction motor IN_PU4040 of 1.3 MW which controls one of the four large inflow pumps tothe plant. The reason for the latter measurement was due to registered negative transients eachtime the motor was connected to the grid. The cause of the transients could be explained by thecoupling in the substation, the ageing of the motor which could result in damage of thebearings or resonance in the motor circuit which amplifies high frequency harmonics.
Natursyn och kärnkraft / View of nature and nuclear power
Kärnkraften har så länge den funnits varit en omdebatterad energikälla. Syftet med denna
uppsats är att utreda och få en bild av hur och på vilket sätt natursynen hänger ihop med
åsikter om kärnkraft. Jag har redogjort för vad energi är, kärnkraftens historia i Sverige och
som energikälla samt beskrivit för- och nackdelarna med kärnkraften. För att kunna ge en bild
av kärnkraft och natursyn har jag genomfört kvalitativa intervjuer med personer som på olika
sätt är insatta i problematiken kring kärnkraften. Min undersökning visar bland annat att
natursyn är ett komplext och stort begrepp som vi bör vara medvetna om hur det fungerar i
arbetet för att förbättra miljön..
Visualisering av hovleden hos häst med magnetresonanstomografi
Lameness localized to the hoof is a common problem in horses. Magnetic resonance imaging (MRI) as a diagnostic tool is becoming more common and is well suited for examination of the distal limb and the hoof capsule. Today there are two different methods of MRI where in one the horse is under general anesthesia and in the other the horse is standing and only sedated. In this study we have compared the visualization of the distal interphalangeal joint using these two methods in two different groups of horses with unknown clinical problems referred to two different equine hospitals. The width of the joint structures including thickness of joint cartilage and joint fluid and also the width of the dorsal pouch of the distal interphalangeal joint were measured.

Investeringar i småskalig vattenkraft vid befintliga dammar : - En studie av teknik-, ekonomi- och miljöfrågor
In this thesis a method for evaluating investments in small scale hydro power is presented. An analysis of the future position that small scale hydro production will have on the Nordic electricity market is also carried out. This is done by an inventory of technology and economic and environmental aspects. The inventory is also a guide as to how the project should be implemented.Hydrolyzer is the name of the Excel tool developed to evaluate investments. The tool requests input data from the user and then evaluates the investment and generates a sensitivity analysis.
Värmning av avloppsvatten med spillvärme för att förbättra kvävereningen -Temperaturens inverkan på kvävereningen
The goal for this master thesis project has been to investigate the power quality in adistribution grid, which has a high fraction of dispersed power production due towindmills. The study has been done on a grid in Laholm South of Halmstad, whereapproximately 45 windmills are connected to the distribution grid owned by SHKEnergi. The investigation has been focused on to two radialy fed 20 kV lines, wheretwelve windmills are connected.Voltage variations have been studied by creating a model of the grid in the simulationprogram SIMPOW. The largest deviation that has been found in any point of the gridis ±1.9 % of the nominal voltage. This deviation is a result of varying powergeneration from the windmills and the voltage regulation at the connection point ofthe line.
Hårdare tag mot brottsligheten? : Tre etablerade politiska partiers syn på kriminalitet och kriminalpolitik
This study analyzes the political view of criminality and crime politics in three political parties in the Swedish parliament, Socialdemokraterna, Folkpartiet and Moderaterna. The study seeks to describe which kind of view these parties present on the criminality in our society. The material for this study is the ideologies that the parties descend from which are, socialism, liberalism and conservatism, the political programs of these three parties have also been studied as well as the parties proposals, political documents in the Swedish parliament. The current public debate shows that the crime politics is an attractive question and the parties may seem to have similar proposals on how to lower the criminality in our society. The theory that has been used to describe the results of the study is ?actors and structures? and the results are related to this theory as well as the theory has been used as an instrument to explain and sort the material and the results.The results of the study show that the parties are different in their views on criminality as a problem in our society.
"... ingen ska få säga att jag inte ska höra!" - en studie om brukares hörselsituation på vård- och omsorgsboenden.
Background: First Line Managers are expected to create a health promoting work environment. Research has shown that the prerequisites for accomplishing a health promoting leadership are not always the best. Aim: The aim was to elucidate the prerequisites for a health promoting leadership as First Line Manager at a University hospital in Sweden based on competence, role, support structures and own durability. Results: First Line Managers at the chosen hospital seems to have rather good conditions for conducting a health promoting leadership. All respondents did have a university degree and most thought that their competence corresponded well with the role.
Chromatin functions : the DNA repair connection
The aim of this master thesis was to examine a possible connection between chromatin functions and the DNA damage repair system, with the imprinted IGF2/H19 locus as a bait. Interactions can occur within and between chromosomes and it has been shown that H19 ICR on both alleles can communicate with alleles on other chromosomes. The methylation-sensitive insulator protein CTCF is bound on the maternal H19 ICR and acts as an insulator by blocking the IGF2 promoter to access its enhancers. This is possible by formation of loop structures by CTCF that enables intra and inter-chromosomal interactions. CTCF is poly(ADP-ribosyl)ated by PARP-1 when it is bound to H19 ICR.
Beräkning av värmeförluster och energieffektivisering av elbussar
The ?civilized? world is in need of fossil fuel in order to function. Hybricon AB is a company in Umeå that is developing a technology that hopefully can reduce parts of this need. They are currently testing their two electrical busses (with Hybrid backup) in city traffic on the roads of Umeå in cooperation with the county of Umeå. The busses are originally diesel-busses, but the diesel motor has been replaced with two electrical hub-motors with a power of 145 kW each that are powered by batteries.The batteries are charged at the end station after each route. In case the batteries should run low on capacity during driving, they can be recharged by the so called genset.
