The technological legacy from the early electrification of the Swedish railroads has resulted in a power grid with a lower grid frequency than the national power grid from which it is fed. Energy transfer between these power grids with different frequencies requires substations, adapting the grid frequency for the rail road power grid. For this purpose, a feeding power grid has been built, stretching across the country from Boden in the north to Tälle/Häggvik in the south.Power transfer in the Swedish power grid results in voltage angle differences which increase with increasing loads and transfer distance. These voltage angle differences are transferred from the power feeding substations to the rail road power grid, will in some extent cause loss of energy due to unwanted power flows from north to south.To minimize the losses due to this phenomenon, a power management system called EFS 132 kV has been developed and implemented. The system minimizes the unwanted power flows and controls the desired power flow for a good distribution of loads between the power feeding substations.This thesis investigates the extent of the transmission losses avoided due to the EFS 132 kV that coordinates the idling angles to a common reference point.The results indicate that EFS 132 kV affects the power flow, especially between the northern substations through an improved load distribution.

Place as a concept, and memory as a phenomenon is researched through literature studies. The essay investigates how we think about place and how we experience and relate to it. Memory is discussed both as personal memory and collective memory. Place is a strong source of memory. When we return to a place, we recognize not only the place itself, but also the things we did there, the people we met and the thoughts passing through our mind when we last were there. Pieces of ourselves are stored in the memories awaken when we revisit a place.

This is a study of humanity about the meetings we have with one another. I write about this subject out of the perspective of Martin Buber and Gustaf Wingren. As I enter this area and begin the writing a few questions are being developed, such as:? Why do we as humans have the need to meet each other?? ?What happens with us when the meeting is absent?? ?What does it mean to love your fellow man or woman?? ?What helps or destroys our possibilities to meet each other?? Buber talks about Me and You and the aim of the meeting we have with each other. When we meet each other it generates a responsibility against each other.

VAV (Variable Air Volume) system has been studied in a newly constructed office-building. The goal for the study has been to evaluate how the ventilations system work in practice, if adjustments can be made to achieve an more energy efficient system and to evaluate if other alternative ventilation systems is to be preferred in the further.The degree project has been executed at Helenius Engineering Firm who is working with the environment, media systems, HVAC and energy in buildings. The building that has been studied is owned and operated by Akademiska hus.Literature studies, visits at site, inventory, review of system documentation, energy analyses, interviews, key figures, LCC, sand energy- and indoor climate simulations has been made to study the building. Where appropriate some tools from Six Sigma have also been used.How to achieve an energy efficient system and a pleasant indoor climate is studied with human health and well-being as base for the indoor climate requirements. Technical support systems such as ventilation systems have to be designed so that an acceptable indoor climate can be achieved.

Aim: To describe nursing measures for prevention of pressure ulcers among elderly people in ordinary and nursing homes. Method: A literature review by structured analyze of scientific articles. Result: The analyze resulted in six subjects for prevention of pressure ulcers. These subjects were; risk assesment, nutrition, repositioning, skin/hygiene, nurse knowledge and documentation.

The purpose of this study is to examine the medial depiction of Muslims in the case of Pastor Terry Jones' intention to burn the Quran. Our study is based on theoretical framework regarding an alleged clash of civilizations, how that leads to global conflicts and controls the world politics. It?s also based on the western way of characterize Muslims as violent, irrational human beings, and how mass media have a tendency to depict Muslims as ?the others?. The questions we aim to seek answers to are: How were Muslims portrayed in CNN's and Al-Jazeera's reporting regarding Terry Jones plan to burn the Quran? Which discourses exist about Muslims in each news channel and what are the main differences between them? The qualitative method used is a critical discourse analysis on empirical data consistently of twelve articles.

As the companies of today are good at protecting themselves against external threats, but are having problems with internal threats, we focused on how information can be protected from ending up in the wrong hands. First and foremost to protect information from employees who might steal it and sell it to another company. Since the security investments needed are connected to the financial costs of implementing them we have tried to create a balance between the investments needed and the cost of implementing them. The different kinds of protection needed are first and foremost protection to make data less accessable, passwords and traceability. While it is hard for us to estimate the amount of money a company lose by the hour when the production stands still, we have not been able to use any of the excising models to calculate the profit of installing countermeasures.

Throughout the history, the theories which have shaped our cities have varied from time to time. We have gone from a city development characterized by spontaneousness, where commerce and people side by side shared the space, into a function-based planning where people and functions are being increasingly separated. Regardless the forms of planning the city design causes implications for those who live there when the physical environment controls were we live, work and meet. In today's society where `sustainability ' has become a watchword the current community planning needs to be questioned so we, in the best possible way, can meet future changes. Searching for new planning strategies is part of this and in this essay the term `mixed-use´ will be investigated and analyzed in terms of its social aspects.

Sweden is usually seen as a role model when it comes to integration and diversity, but at the top of the pyramid there is little ethnical diversity to be found. This paper investigates how existing economical and sociological theory explain the lack of swedes with foreign background in leading positions in large Swedish companies. Our findings show that none of the theories applied in this paper can explain the phenomenon in isolation. Thus it is not only taken for granted norms, contacts in one's network or cost minimizing under asymmetric information that lie behind the phenomenon, but an interaction of these aspects. Conflicting demands lead the recruiters to separate talk from decision, the search frame is narrow and no or small efforts are made to increase the diversity.

Marketing communications have earlier been conducted via traditional channels. Today companies have discovered the possibility of doing much of their marketing communication in cooperation with the web at relatively low cost. This development has led to the ability for small businesses to compete with large companies independent of geographic location. The purpose with this thesis was to examine how small businesses use their website in marketing communications with their customers in the consumer market. In order to reach this purpose we have conducted interviews with five small businesses in different business trade with varying degrees of website usage, located in Piteå and Luleå.

The purpose of this study is to incrementally, through a combination of various methods, examine the assumptions about the working economic outcomes that can be made based on planned ergonomic intervention in a department at Pfizer Health AB in Strängnäs. The study contributes to knowledge about how assumptions on OSH financial results can be made, based on planned ergonomic interventions. These assumptions were based on biomechanical calculations made on the basis of ergonomics measurements with inclinometer. The study is important because previous research has shown that poor work environment have a bad impact on the economy of a company in different ways. It can for example be negative impact on the company's productivity and quality of the units produced or the services provided.

Drain water heat recovery is an uncommon measure in multi-unit residential buildings. There istechnology available for the purpose but the knowing and experience of the heat recovery systems islittle. The purpose of this thesis is to evaluate the future potential of drain water heat recovery inmulti-unit residential buildings.A major part of the multi-unit residential buildings in Sweden were built during modernismen andrekordåren (1940?1975). Many of the buildings have worn out drain and water supply systems andmany are in need of a general refurbishment.
