Elanslutning av fartyg i hamn : en studie om förutsättningar och konsekvenser för Köpings och Västerås hamn
The purpose of this thesis is to investigate the possibilities for shore side electricity in the ports of Västerås and Köping. A technical solution to connect the vessels to the local grid is suggested and the investigation is also aiming at an understanding of how the environment is affected by the use of shore side electricity. Furthermore, the costs of shore side electricity are considered.The maximum power demand of a vessel visiting the ports today is relatively small, but the ships visiting the ports in the future might have a larger power demand. The suggested dimension for the system is 5 MW and the result shows that the shore side electricity requires the power distribution to the ports to be expanded. The most useful solution in the ports is to connect the ships with 12 kV from a connection box in a pit at the quay.The investigation of the costs shows that it is cheaper for the ships to use electricity compared to the marine fuel.
Peltierelement - spillvärme till el : Peltier element - waste heat into electricity
The purpose of this thesis has been to determine experimentally how good a peltierelement is to convert waste heat from wood burning. Three different peltier elementswere used in a comparison study. The comparison was mainly done to know howmuch power could be obtained from each element. Even, a circuit with a step-upfunction has been created to give a higher output voltage than the peltier elementitself. The result of the experiments was a low output power, the highest valuereached 2.18W.
Storleksoptimering av en etanolfabrik för integrering med ENA Energis kraftvärmeverk. : Baserat på en regional energibalans mellan tillgång på etanolbränsle i Enköping kommun och producerad etanol med hjälp av tillgänglig ånga från ENA kraftvärmeverk.
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.
Sjuksköterskans möjligheter att upptäcka och stödja den äldre deprimerade patienten
ABSTRACT
The persons whom the authorized nurse encounters in hospital wards and nursing
homes are in great extent elderly persons. According to Wasserman (2000), about
30 to 40 percent among these, show signs of depression. To be aware of the
signs of depression, and how an authorized nurse can support the patient is
therefore of great value. The introduction to this study describes the symptoms
of depression and how depression in elders is expressed. It also describes
treatment possibilities and nursing aspects of concern.
The aim of this study is to illustrate what possibilities the authorized nurse
has to detect and to support the depressed elderly patient.
Redesign av Vagabonds guideboksserieThe travelguides of Vagabond - Redesign
Todays travel trends go towards independence and self planning. If you need advice or help when performing your trip, there are several different series of guidebooks on the market and one of these series comes from the travel magazine Vagabond. This degree project concerns the redesigning of the travelguides of Vagabond, or to be precise: their cityguide over Istanbul. The purpose of the new design is to assure the resemblance between the guidebook and the magazine, as wanted by the Art Director of Vagabond Angelica Zander.Prior to the redesigning process preliminary studies that make up the fundamental ideas were made. Three other big titles of guidebooks on the market were analyzed, and in addition a great deal of focus ? considering the final purpose ? was put on the concept of magazine design.

Kommunalt klimatarbete : Jämförande studie mellan tre kommuner med avseende på drivkrafter och framgångsfaktorer
The crucial factor for successful municipal climate work is that there are driving forces. Most importantly is that the senior officials and politicians in the municipality are dedicated to the cause considering that they have the power to influence and make a change. Besides proactive and committed individuals, it is necessary that the work is organized and anchored by clear and concrete documents and control systems. It is also important that the work is continuously monitored and evaluated. To collaborate with other municipalities, authorities or participate in various networks is another factor contributing to the improved climate work in the form of exchange of information, knowledge and experience.A major driving force for municipalities to improve themselves is the distribution of state aid and grants.

Pedagogisk dokumentation : Ett perspektiv på lärande i förskolan
This study deals with pedagogical documentation. With a revised preschool curriculum,where this is a crucial aid for illustrating the learning process of children and educators, aswell as demonstrating the activities of the school, it is of the utmost relevance to further explorethis notion. The study focuses on a single municipality and explores the various ways inwhich its preschools do in reality deal with this issue in correlation with the actual visions andgoals set by that municipality. Through a series of qualitative interviews with educators aswell as with the municipality Head of Education, this study outlines how educational documentationis in fact applied in the schools in question. The gathered data has been interpretedwith a power perspective as well as with a sociocultural perspective in mind.
Hantering av småskalig elproduktion : Utveckling av modell för dokumentation och elkvalitetsberäkningar
The interest in small-scale electricity in Sweden has increased strongly in recent years. The interest is noticeable both among politicians to increase the share of renewables in the energy mix, and among electricity consumers to partially replace purchased electricity with self-produced. This has resulted in a significant increase of electricity production in low voltage grids in recent years, and the trend appears to continue in the coming years. The majority of the new production plants are solar cells, followed by wind turbines, and it is also in these the greatest efforts are made in this paper.Distributed generation is often seen as something positive since it will contribute to reduced transmission losses and reduced voltage drop in the networks, and that it increases the share of electricity from renewable sources. In cases where the grids are not strong enough, or in other ways not adapted to manage the installed production, power quality may be adversely affected.
"Peshmerga-chic" och "Nipster" : En kritisk diskursanalys om hur modet samspelar med vår förförståelse och hur det analyseras i media
Fashion creates reactions. It is a type of art form that constantly needs to be updated. This is the thrilling part about fashion, but it is also the part that can create unintentional reactions.In this essay I will examine two garments that have achieved a great amount of media coverage, both in Sweden and abroad. One of them is a jumpsuit from H&M that was criticized because of the resemblance to the uniform worn by the Peshmerga-soldiers in Kurdistan. The other garment is a children?s sweater launched by Zara.
Orsaker och sammanhang kring avvikelser i processen med prefabricerat byggande
The purpose of this thesis has been to develop a tool for modelling and simulating the nuclear plant Ringhals 3. The model should be used to improve the knowledge on the dynamics of the plant. Ringhals 3 is being upgraded to produce more power and a tool for analyzing the new operating conditions is needed.The work in this thesis has consisted of improving and developing an existing model of Ringhals 3 made with the modelling tool Dymola. The model has been validated by comparing the results of a simulated house load transient with data from the actual plant. Validation shows good agreement with data from the real plant.
?Något fel är det med honom, han kommer säkerligen aldrig att bliva en god medborgare? : En studie om barnavårdsnämnden, skolan och de avvikande barnen i 1930-talets Malmö stad
This study, a document analysis with a qualitative approach, explores children, under 18years, who have been subject to measures of child welfare in the city of Malmö during theyears 1935-1937. It also explores the school's role in this context. The questions that the studyis guided by is: How was children described in the Child Welfare documents in Malmö duringthe years 1935-1937? And what role did the school have in Child Welfare work and whatmotivated this? The theoretical approaches are Foucaults theories of power, control anddisciplining.It appears from the study that the school and child welfare authorities had a close cooperationwith the purpose to control the upbringing and disciplining of the children. It was through theupbringing that the deviant child would become a "normal", docile and good, industriouscitizen.
Konflikt på flykt - Analys av flyktingströmmars påverkan på konflikterna i Great Lakes-regionen.
Konflikterna i Great Lakes-regionen har präglats av både flyktingströmmar och etniska dimensioner. Vi har genomfört en fallstudie på detta område för att undersöka vilken betydelse flyktingar har för konflikterna i regionen.Vi visar hur flyktingströmmarnas karaktär och flyktingskapets utsatthet leder till skärpta etniska spänningar och bidrar till försvagandet av stater. Flyktingarnas osäkra livssituation och kollektiva minnen innebär ett särskilt starkt identitetsbehov, vilket kan leda till ökad etnisk polarisering och gör att de blir lätta att mobilisera politiskt.Flyktingströmmar orsakar ett allvarligt försvagande av stater, eftersom de på ett fundamentalt sätt underminerar statens legitimitet, genom exempelvis deras förlorade förtroende för staten och dess institutioner samt deras inblandning i väpnade attacker mot hemlandet.Generellt uppmärksammas flyktingströmmar oftast bara som en allvarlig konsekvens av konflikter, men vi visar hur de också kan förstås som en starkt bidragande orsak till inomstatlig och regional instabilitet..
Riskmodell för kabelsträckningar i mellanspänningsnätet i Sverige
The society of today is largely dependent on electricity and the dependence does not show any signs of declining. Reliability of supply will become increasingly important in the future and it is therefore important to investigate factors affecting the failure rates in electrical components.Sweden was hit by several severe storms during the 00?s. As a result of this many overhead lines in forests were cablified. In urban areas underground cable systems have been the norm for many years.
