Utvärdering av beräkningskoden APROS för användning i inneslutningsanalyser
At Forsmark nuclear power plant the rather old-fashioned software COPTA is used in containment safety analysis. There exists a desire within the organisation to introduce a more modern software with ability to more detailed modeling and increased usability.The goal of this thesis was to evaluate the software APROS in containment safety analysis. APROS models describing one of the containments at Forsmark NPP have been developed. Two simulations of typical containment incidents, one of them a large pipe break, have been made where containment safety parameters such as pressure and temperature are studied. Results are analyzed and verified against results from corresponding COPTA models.
Vanebeteende - Det lojala beteendet?
The Swedish sports retail industry has experienced extensive growth during the last decade, and this has attracted new entrants to the market, both start-ups and international followers. This has inevitably put more pressure on incumbents, which are now confronted with major challenges as how to retain their customers and market shares. Customer loyalty has been proved to be an important factor for customer retention and proposed to constitute inertia of switching behavior. In light of this problematization, the purpose of this study is to describe the underlying factors of loyalty and whether purchase habits could further explain customer loyalty. The aim is also to understand the strategic implications of the factors involved.

Det är det lilla som gör det stora : -hälsofrämjande åtgärder vid hypertoni
Hypertoni är vanligt förekommande i dagens samhälle och anses därför ha blivit en folksjukdom. Uppskattningsvis har 1,8 miljoner av Sveriges vuxna befolkning hypertoni. Hypertoni står för cirka 13 procent av den totala dödligheten i världen, och ses som en riskfaktor till ett stort antal hjärt- och kärlsjukdomar. Idag finns det internationella riktlinjer för vård av hypertoni i bland annat England och USA. Dock saknas det specifika svenska riktlinjer för vård av hypertoni.
En Modell av SOA för Agila Organisationer
In a dynamic and unpredictable reality, either rigid structures or silo architectures areappropriate ways to organize an agile organization. This thesis enlightens these relationsbetween Service Oriented Architecture (SOA) and an organization who acts in a varied andconstantly changing business environment. In other words, this thesis enlightens the question:?How suitable is SOA to organize the enterprise who will meet a constantly changing andheterogenic business environment?.The thesis presents a model where an efficient organization must be agile to be able to actquickly in the business environments with constantly changing desires, needs, expectations,desires etc. According to the same model a Service Oriented Architecture organizes theenterprise elements such as processes, resources, competences, responsibilities, informationsystems etc.
Vad formar ungdomars attityd till rökning : En kvalitativ studie
Syfte:Syftet med undersökningen var att beskriva vad som formar ungdomars attityd till rökning. Metod:Sex kvalitativa intervjuer genomförds med ungdomar i åldern 14-15 år. Kategorier utarbetades genom analys av intervjuutskrifterna. Resultat:Det framkom att ungdomarnas attityd formas dels av yttre faktorer som närståendes rökvanor och dels av inre faktorer som nyfikenhet. Ungdomarna ansåg även att om cigaretter varit så ohälsosamma som det påstås så hade de varken tillverkats eller sålts.
Den eritreanska transnationalismen. En studie av den eritreanska diasporans engagemang i Eritreas utveckling
The ability of emigrants to contribute to their homelands through the sending of remittances has been intensely recognised in recent years. This is especially true for developing countries for whom this money is seen to be an important source of funds from abroad. Eritrea is often mentioned in terms of success in the way they have mobilised the capacities of their diaspora. Since the Eritrean independence in1993 adults in the diaspora have been asked to contribute two per cent of their income to the Eritrean state. They have also been asked to make other donations at times of need.
Uppgradering av biogas i systemperspektiv med avseende på miljöpåverkan och kostnader
Swedish biogas is currently produced mainly by anaerobic digestion of sewage sludgeat sewage treatment plants, landfills and anaerobic digestion of household or industrialwaste. Also cattle ma-nure from farms can be used to produce biogas. Upgradingbiogas represents an increase in methane concentration from about 65 % to about 97%. In addition, particles and contaminants must be sepa-rated from the upgradedbiogas. There are various methods for upgrading and this report compares sixdifferent methods with respect to environment and economy: water scrubber,Biosling, cryo technology, chemical absorption, Pressure Swing Adsorption (PSA) andmembrane separation.According to the used ORWARE model, chemical adsorption with amine has the leastenvironmen-tal impact (methane emissions) and the lowest costs.

Journalist, javisst! En förändrad mediebransch ur ett motivationsperspektiv
Given the turbulent situation in the Swedish media industry few researchers have turned towards the view of the situation from the perspective of the journalist who is in many ways under pressure. This study therefore aims to take this perspective by combining recent research in the media field with proven theories in the field of motivation. Through deep interviews with eight journalists active in the general news reporting area, the most important factors in terms of their motivation have been suggested and analyzed. There is a distinction between different types of motivation including intrinsic and extrinsic aspects. The intrinsic factors include investigational journalism and the social part of doing research.
Det är ju samma arbete fast annorlunda : marknadsmekanismers inverkan på hemtjänstpersonalens arbetssituation
Many organizational changes have been accomplished in elder care since the 1980's and many of those have been influenced by market mechanisms. The purpose of this study is to examine how the implementation of these market mechanisms has affected three important aspects in the work situation for personnel. These aspects are, demand, control and support. To attain the purpose of this study, five qualitative interviews with home care personnel have been carried out. The interview material has been analyzed and structured with the help of Karasek and Theorells demand-control-support model.
Termisk hantering av litium-jon- batterier i elektriska drivsystem
The automotive market is currently undergoing a historical change where stricter emission legislations and ever increasing fuel costs have intensified the search for effective alternatives to the conventional internal combustion engine, which has resulted in a substantial trend towards electrification of powertrains. Storage of electrical energy is the fundamental component in this technology where the lithium-ion batteries are currently considered as the most appropriate solution. Lithium-ion batteries, however, as other types of batteries, can only be used efficiently and durably within a specific temperature range.This Master thesis has been carried out in collaboration with Electroengine in Sweden AB, situated in Uppsala, which has an ongoing project regarding development of a modular battery system for electric powertrains. The project is at a stage where an initial prototype has been developed which provides the foundation for this thesis. The study has addressed the battery system performance from a thermal perspective, in order to validate the ability of the system to create a thermally serviceable environment for the lithium-ion battery cells.
Kan kombinationen av dehydrering, kronisk stress och/eller endotoxemi vara orsaken till träningsinducerad lungblödning?
Thoroughbred racehorses have suffered from exercise-induced haemorrhage for over 300 years. Almost all competing horses develop exercise-induced pulmonary haemorrhage (EIPH) at some point but most horses don?t suffer from reduced competing capacity due to the disease. The cause of the exercise-induced haemorrhage is unknown. The most believed theory today is that EIPH is induced by pulmonary stress failure caused by pressure over 100 mmHg in the pulmonary arteries during exercise.
