Effektiv tillsyn av pågående verksamheter i Piteå kommun med MIFO fas 1 som verktyg : Underlag för strategival
The purpose of the study was to investigate how inventories of suspected polluted areas as a part of the planned control of existing companies cab be designed in order to achieve as great effect as possible. The study was conducted in cooperation with Piteå municipality. An analysis of regional inventory projects, local municipal strategies and a pilot study in Piteå was conducted. The experience from both the regional projects and the pilot study was that in order to achieve an effective control a number of factors were inportant: an efficient selection of companies, a good dialogue between the controlling agency and the companies, sufficient resources, education of municipal inspectors and guidance for decisionmaking. Another inportant result was that the municipal planning can prevent an efficient inventory if the control of city development projects is allowed to take time from the planned control.

Förbättrad förbränningsstabilitet i EBK för turbofläktmotor RM12 genom förändrad motorreglering : Improved afterburner combustion stability for turbofan engine RM12 by modified engine control
The engine of JAS 39 Gripen, RM12, has recently been equipped with a new flameholder and a new engine inlet. This change has caused an increased noise level from the engine when the afterburner is in use. The noise level reaches its peak when the afterburner is partially used. The problem is thought to be unstable combustion in the regions around the flameholder. A solution to the problem has been proposed by Volvo Aero.
Tilla?mpning och simulering av naturlig ventilation : Potential fo?r utnyttjande i kontorsrum
Mechanical ventilation is the most common type ofventilation in newly constructed office buildings. Therehas been an interest to utilize natural ventilationinstead of mechanical ventilation among architects andHVAC consultants in recent years. This is due to thesize of mechanical ventilation systems, which arespace consuming. The mechanical ventilation system isalso complex and requires maintenance. Furthermore,the fan uses a considerable amount of energy.
Energi - och ekonomipotential för solceller i Hållbara Järva
One of the city of Stockholm?s main objectives is to have a society completely free from fossil fuels. To achieve this, several investments regarding improvements in energy efficiency and renewable energy are currently being planned or implemented. One of these investments is a project called Hallbara Jarva which is located in the suburbs of Stockholm. The purpose of this thesis is to examine the prospects of an investment in photovoltaic cells from an energy-saving and economical point of view. The analysis is limited to three buildings within Hallbara Jarva and is intended for the property owner. Solar energy is a type of renewable energy source and is commonly divided into solar heating and solar power.
Kontrakt med Självet eller med Chefen - Kan personlighet predicera proteiska karriärattityder?
Tidigare ombesörjde organisationen karriär och karriärutveckling för den anställde och karriärkontraktet byggde på livslånga anställningar. Det nya karriärkontraktet bygger istället på en så kallad proteisk karriär (Hall, 1996), vilket utmärks av att individen ser sig själv som ansvarig för och drivande av sin karriär, att egna värderingar får styra samt att psykologisk utveckling är främsta mål. Studiens frågeställning var att undersöka om personlighetsfaktorer i termer av self-efficacy, självkänsla, locus of control samt neuroticism kan predicera proteiska karriärattityder. I studien användes kvantitativ metod och en enkätundersökning genomfördes på studenter. Korrelationsberäkningar visade att samliga personlighetsfaktorer samt proteiska karriärattityder var korrelerade.
Säkerhetsanalys av brandbekämpning i kritiska utrymmen på Forsmark 1
In order to maintain a high safety level at a nuclear power plant it is important not only to measure the reliability of the components and systems of the plant, but also to investigate how the plant responds to human actions. One of the most hazardous situations in managing a power plant is fire occurring in critical areas. This study concerns the prospect of the local fire brigade to suppress a fire that has started in one of the most critical rooms for maintaining high reactor safety. The model created gives an indication on the possibilities of succeeding in suppressing a fire. In order to get a more reliable fire fighting the following advice are given:- Let the fire brigade go rounds in the plant together with the personnel, during which recommended fire suppressing methods are determined to avoid long preparation time in an actual situation.- Prepare rooms with two subsystems to make them partly with no voltage.- Give the fire brigade better feedback from actual events on nuclear power plants.- Education and training in suppressing fires in electrical equipment.The probabilistic safety assessment strives to be as realistic as possible.
Analys och organisering av ö-drift för en samförbränningsstation vid Åmotsfors bruk
Åmotfors Bruk AB (ÅBAB) has today an inefficient production of steam for the
manufacturing of paper. Unpredictable energy prices and modernisation of the current
equipment has been the underlying factors to invest in a thermal power plant, mainly
driven by garbage. This facility will not only use the steam for paper production, it will
also generate electricity through a steam turbine. Today, when a fault on the supplying
line occurs which leads to disconnection of the external grid, all the support of electricity
to Åmotfors Bruk (ÅB) will disappear. This will lead to major interruptions in the paper
production, which will cause severe economical losses.
E.ON:s transformatorflöde - en studie av återanvändningen av transformatorer i projekt krafttag
Problem StatementAfter the hurricane Gudrun in January 2005 EON Elnät Sverige AB started the project KRAFTTAG, were 17,000 km of the airborne power grid shall be replaced with cables underground. The transformers in the airborne power grid shall be dismounted, renovated if necessary and then conveyed to stations, of type kiosk.Additional new transformers, more than planned, have been bought. This is due to the dysfunctional transformer flow from the demolished power supply to projects, were the new power supply is built, the general picture is complicated, since the reconstruction involves other companies and many employees at E.ON.PurposeThe purpose of this master thesis is to map and understand the existing transformer flow. The objective is to make a recommendation on how to increase the level of E.ON? s transformer recycling.Methodthe authors have worked with a system approach, including both qualitative and quantitative data.

Hon tar vad man vill ha : en studie av sexuella maktrelationer i samtida relationsromaner
The aim of this study is to analyse the sexual power relations in contemporary urban novels of Swedish female writers.I have identified a discourse in these novels as a heteronormative matrix which power is ruled by norms and assumptions about normality in both the heterosexual and lesbian stories. For this purpose I have related to Ivar B. Neumanns theory that individuals always find a way to confront the discourse by three different strategies. These strategies are used in my study as tools to organise these novels, because it is possible to see that the protagonists find at least one of these strategy?s to her protest.The first strategy I studied was the docile.

Förnybara bränslen är lösningen, vad är problemet? En maktanalys av den svenska dagordningen för förnybara bränslen
The aim of the thesis is to examine how central collective actors in the Swedish subsystem of renewable fuels use their positions of power and influence to their own specific interests and needs. In particular the thesis looks at the problems of climate change and oil scarcity and how renewable fuels are described as a potential solution. Using agenda setting theory and Steven Lukes three dimensions of power as a framework, five actors are examined and analysed. The study has been done in two parts. In the first part policy documents are analysed concerning the actors general stance towards renewable fuels, and how this is communicated to the media, politicians and public.
