Hjälpkraftsystem med två lågspänningsnivåer
Because of increasing demand of power on Malmbanan the capacity of the existing wires which supply the trains must be increased. This increases the stress on the existing poles and for this reason the system for supplying the loads along the railway is to be removed from the poles and be replaced by some other system. This thesis is a study on a two-level low voltage (1 kV and 0.4 kV) electrical system with the aim to investigate if it can be an alternative to the system used today taking into account the voltages, fault currents and costs.In this thesis the following tasks have been performed:? Gathering of data? Description of basic theory? Loadow and fault current calculations of the system with MATLAB? Life Cycle Cost estimate of the system? Analysis and conclusions from the resultsThe results show that the new system can be an alternative to replace today's system. The simulations and calculations show that the voltage drop is at an acceptable level and that the fault currents are large enough to supply a safe disconnection if a fault occurs at the far end of the system..
Gotlands solelpotential
The aim of this thesis is to investigate the electric solar potential on the Swedish island Gotland. The Gotlandic habitations have been divided into four house categories. For each category energy demand, roof area, geographic orientation androof tilt have been decided. Solar radiation data have been collected from the Swedish solar radiation model STRÅNG (STRÅNG, 2012).The buildings characteristics and the solar radiation have been used as input values in common solar formulas, the solar potential for each building category have been summed up to a total electric solar potential for the region.The electric solar potential on Gotland was calculated to 242 GWh/year with solar data from 2010. Gotlands largest city, Visby, is marked as cultural heritage by UNESCO (UNESCO, 2012).
Sjuksköterskans möte med Anorexia Nervosapatienter : vägen till en relation. En litteraturstudie
Anorexia nervosa is a severe and multifaceted eating disorder generally found in the female population. Throughout anorectic starvation relationship related conflicts revolving round power and autonomy are bound to happen. For that reason the most crucial part of treatment should be to build a trusting relationship.The aim of this study was to describe relationship promoting strategies a nurse can use during care of anorexia nervosa patients. This literature study derives from a qualitative analysis of scientific articles. The findings indicate on five different strategies a nurse can use during care of anorexia nervosa patients.
Dagligvarumarknaden : en samhälls- och distributionsekonomisk analys av internet som försäljningskanal
Structural changes on the grocery market usually take place when the consumer is persuaded to take on the more labourintense parts of the distributionprocess. Internettrade changes this by causing competition between the unpaid work done by consumers and the labor performed by employees. In this master thesis grocery shopping on the internet is analyzed in a economic perspective with focus on distribution, changing marketstructures, driving forces and the future potential of internet as a saleschannel. The main conclusions are that consumerdemand and the belief in electronic commerceas a costreducing mechanism as well as a powerful new marketing tool were the driving forces behind the fast growth of grocery shopping on the internet. Electronic commerce introduces a new model of distribution with changing roles for consumers and grocerychains.

Ett attraktivt snittblomssortiment från perenner odlade på friland :
The production of cut flowers has diminished in Sweden and the remaining growers produce mainly in greenhouses. This situation could be changed if hardy, garden perennials suitable for Swedish conditions were to be used as cut flowers. A grower with suitable equipment as plastic tunnels or houses would be able to provide florists with an attractive assortment of perennials for cutting, during an extended selling period compared with the natural flowering period for these cultivars. This assortment would be based upon imported perennials already used by florists, but would also contain new products. To investigate the demand for locally field grown perennials as cut flowers, an inquiry took place.

Historien om hovleverantören ? en studie i användandet av Corporate Storytelling
Corporate Storytelling är ett relativt nytt begrepp inom marknadsföringsområdet. Mycket kortfattat kan det förklaras som en teknik där företag använder sig av berättelser för att förpacka varumärkets värderingar på ett fängslande sätt. På så sätt hoppas företaget väcka engagemang och intresse hos konsumenten samt få åhöraren att föra budskapet vidare. Corporate Storytelling är svårt att kvantifiera, då alla företag och deras berättelser är unika. Därför har vi valt att selektera en specifik grupp företag ? Sveriges kungliga hovleverantörer.
Bibliotekarien som distansarbetare? : förutsättningar för bibliotekarien att utföra sina funktioner på distans
We studied how librarians would adapt to telework, the performance of job responsibilitiesfrom home. We found'that all duties could be accomplished. but to varied extents.Computerbased searches, interlibrary loans, acquisitions, indexing and telephone referenceservices are the duties most likely to adapt to telework whereas cataloguing andclassification probably are best performed in the ordinary workplace.Most duties would demand access to technical means of assistance when performed fromhome. Connections to the library's local network, directly or via modem, are requiredbecause it is unrealistic to expect librarians to telework with fewer tools than theyordinarily have available. Although librarians generally believe that teleworking will nothave a large irnpact on the operation of the library, most would like to telework.Whether teleworking is a viable strategy depends on the characteristics of the duties, thelibrarian's desire to telework, but also on the size of the library, the size of its staff, thelibrary's activities, and how work is distributed between librarians..
Arbetsvillkorens samband med sjukfrånvaro och sjuknärvaro : En studie av hemtjänstpersonal
Sickness absence is a measure of health and is therefore an important issue. To get a complete picture it´s important to also include in the discussion sickness presenteeism, working while ill, and voluntary absence, staying at home without illness. Working conditions have been proven to play a role for the three aspects which is why this study aims to further investigate the connections between them. The method used was secondary processing on interview data collected from two home care teams, one having a low and the other a high sickness absence. The results showed that there were big differences concerning working conditions, where the group with the high sickness absence perceived more stress, less control and less support from colleagues and superiors.

OTEC-Ett energialternativ för enhållbar ö
Ocean Thermal Energy Conversion (OTEC) is a technology that utilizes the temperaturedifference in oceans between the warm surface water and the cold water at 1000 m depthto produce electricity. The purpose of this report is to investigate if OTEC with its synergiescould become a commercially feasible energy solution for a small island. A literature reviewis conducted to explore the different OTEC technologies and to what extent the threesynergies; fresh water, air conditioning and aquaculture, could be used. In order to calculatethe profitability of these synergies there is also a study conducted on the conventionalmethods and cost of fresh water production, aquaculture and air conditioning. A model is setup using a scenario of a small tropical Island with population of 100 000 people.
Val av mätinstrument
Säkerhetsrådet antog resolution 1325 (år 2000) för att förstärka FN:s fokus på förtrycket mot kvinnor och deras roll i konflikt ? och postkonflikt ? samhällen. Det 20:e århundradets ledord blev jämlikhet, utveckling och fred. Resolution 2122 antogs tretton år senare, den understryker fokus på kvinnans rättsliga ställning, denna gång med särskild betoning på kvinnors delaktighet i beslutsprocesser. I uppsatsen har jag undersökt för- och nackdelar i FN-systemet samt folkrätten.
Garantier kontra due diligence vid företagsförvärv : Särskilt om säljarens och köparens ansvar
SammanfattningAv störst vikt vid en företagsförvärvsprocess är huruvida säljaren och köparen reglerar sina ansvarsområden och bestämmer gränser för riskövergången i köpeavtalet. Ur rättsäkerhetssynpunkt är det essentiellt att kunna förutsäga och identifiera riskerna redan vid avtalsslutet. Det ligger ofta i parternas intresse att så långt som möjligt reglera förutsättningarna redan vid ingående och utformning av ett köpeavtal.Syftet med denna uppsats är att undersöka samspelet och följden av att säljaren inför garantiutfästelser i ett köpeavtal kontra resultatet av att köparen faktiskt genomför en due diligence-undersökning innan ett köpeavtal kommer till stånd. Detta genomförs med utgångspunkt i diskussionen kring riskfördelning mellan avtalsparterna, köplagens regler om säljarens upplysningsplikt, köparens undersökningsplikt och den allmänna lojalitetsplikten som åligger avtalsparter.Utgångspunkten vid formuleringen av avtal mellan parterna anses vara det köprättsliga felbegreppet med dess utgångspunkt i köparens befogade förväntningar på det överlåtna objektet. En genomförd due diligence och införande av garantier i köpeavtal kan innebära att riskövergången regleras och de befogade förväntningarna preciseras vilket leder till förutsägbarhet och säkerhet för parterna att kunna förutse eventuella framtida risker.
Lärare och informationssökning. En undersökning av lärares utsagor kring sin informationssökningskontext
The purpose of this thesis is to reach a deeper understanding of the context of teachers? information seeking. Research in the role of the library in a learning perspective is in demand. To reach our aim we investigate what teachers say about their experiences of the user training during their studies and what effect it had on their information seeking as teachers. We interviewed four teachers and analyzed the transcripts of their sayings about their experiences of their information seeking during their education and a teaching profession.
