With gas prices persistently rising, electric and hybrid vehicles are getting more and more common and in recent years several new electric cars have evolved on the market. Although the energy consumption and low emissions are a huge benefit of the electric cars, they inevitably suffer from high prices, short range and time consuming recharging periods. To be able to withstand the competition it is important that electric vehicles not only can withstand general were and tare, but also the harsh conditions that ordinary cars is exposed to in daily usage. The purpose of this project is to develop a test methodology which replicate situations that could appear in daily usage of electric or hybrid cars and to understand the problems related to usage of electric cars in winter conditions. This paper also discusses the major differences between hybrid cars and electric cars.

This report is an inventory of the street lighting in half of the residential estates owned by Karlstad Bostads AB, a public housing company. The inventory was made to reduce the environmental impact of the street lighting. From the inventory an estimation of the total installed power and the energy consumption was made. The total estimated power of the street lighting was 125 kW and the energy consumption was 500 000 kWh/year with an estimated running time of 4 000 h/year. The dominating source of light was 125 W discharge mercury lamps.

During the late 19: th century the park Tivoli in Halmstad, today called Norre Katts park, was known as one of the most beautiful amusementparks of southern Sweden. This is a description that hardly anyone would use to portray the park today. The aim of this study is therefore to investigate what the park once looked like and how it has changed until today?s neglected state. The history of the place and by who and for whom the park with; 4 ½ acers with meandering paths, caves, an avenue, leaf halls and bowers, was created. Who designed the park in the year of 1843 is an unrequited question.

Title: Process description of round timber transports ? a case study at Tra?frakt Go?taland ABAuthors: Karl ? Johan Tern, Christian Johansson and Andreas IvarssonTutor: Anders JerrelingExaminer: Fredrik KarlssonBackground: Today the profitability of forest haulers is unsatisfactory. Negotiations on prices are more about the relative strength of the negotiation parties rather than a discussion about actual costs. Adding extensive changes in the forest haulers cost structure has led to insufficient knowledge of whether the negotiated prices really correspond to their costs.Methodology: We decided to carry out a case study at Tra?frakt Go?taland AB, a special interest organisation whose members represent the majority of forest haulers in Go?taland.Purpose: To describe the processes and underlying activities of round timber transports.

Forensic psychiatric care is a complex business. Patients who are cared for in forensic psychiatry are usually in need of care for a long time. The forensic care is a major intrusion into a person's life and the nurses and caregivers are the people who spend the most time with patients. They have a difficult mission providing a good and personalized care while patients are deprived of their liberty. Previous research demonstrates that patients experience forensic care as uncertain, insecure and punitive but that there are also glimpses of "good care".

Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.

The purpose of this development project is to create a model for working with a high school project in Electrical and Energy Program. It should be conducted in a form like companies do according to the goals from The Swedish National Agency for Education. In order to fully perform this we use the concept of Young Entrepreneurship. The model is created according to the new conditions from The National Electrical Safety Board. There is now an exception saying that a student during education is released from the demand of employment that is the normal procedure where you are under supervision from a certified electrician. During the project there has been theoretical and practical examinations in order to clear out the advantages and disadvantages using this model, but also to examine whether it is useful in the future and to what extent it can be used. The result indicates that the model is useful and fulfills the goals from The Swedish National Agency for Education but that the model has its limitations and difficulties.

The use of earth bricks in Scanian building traditionThe present work is concerned with the manufacturing and use of earth bricks inbuilt heritage in the south Swedish province of Scania. The first part of the studyprovides a thorough description of the traditional use and manufacturing of earthbricks based on relevant literature, archive material as well as interviews withinformants. This forms a basis for the second part of the study in which practicalexperiments on and tests with earth bricks where carried out. This involved themaking of traditional earth bricks of different composition. The new handmadebricks were compared with industrially produced bricks (extrusion bricks) and oldhandmade bricks.

Humidity problems and poor ventilation are factors that we associate with poor indoor airquality which are known to negatively affect health. Such problems have decreased with timein Sweden but, in other countries this is still a major problem especially during winter. InChile, this is most common in the central regions of the country, especially the Strait ofMagellan. This issue is primarily due to surface condensation happening indoors which bringsabout dampness which facilitates the growth of fungus and stains, foul odors, metal corrosionand more. This is due to a combination of poor ventilation and insufficient forms of heatingalong with buildings which have no insulation.

The aim of this study was; from a group of boys and girls description and interpretation of interaction with other young people, personnel and the environment of the youth centre illuminate how the social gender are constructed and maintained at the youth centre. In this study we have tried to analyse the phenomena from an intersectionalistic perspective. Except gender, the analytic category social class have been tried to capture. Our theoretical standing point is social constructivism. Institutionalized structures in our society are constructed by humans, gender is not only a biological construction it is also a man created construction.

In this thesis the survival and development of a yearly recurring event will be examined. The purpose of this work is to examine how the festival Stockholm Pride has developed and to find out what underlying factors and conditions that lays behind the development. Also being examined is how the event affects Stockholm city?s tourism industry. To be able to fulfill the purpose of the thesis a qualitative research has been used and two persons with allot of knowledge about Stockholm Pride and Stockholm?s tourism industry has been interviewed.

A qualitative interview study how the normative gender images affects on women, their roles and positions in a drug abuse. The purpose of this study aims to shed a light at the consequences that the normative gender scenario inflicts on women with drug abuse and how these prejudices affects these women. Based on interviews with four different women who all lived with a drug abuse we have problematized how the gender system and the normative gender images affected them. We have used gender perspectives and social constructivism theories while analyzing the empirical basis. More specifically we use the theories of Butler about how gender constructs through performative actions and Hirdmans theories of the gender system.
