The purpose of this thesis is to evaluate and update load curves for Fortum Distribution AB. Theload curve method is a tool used to forecast the strain of an electric grid. The method is based oncustomer annual energy consumption, outdoors temperature as well as customer category. Theload curve method was established by Svenska Elverksföreningen at the start of the nineties andfocus was put on standardizing annual energyconsumption, in order to make the method usableacross the nation. Present consumption patterns have changed since the original load curves wereproduced, which leads to a need to update the load curves.The work began with an update of present load curves according to recommendation taken fromanother earlier thesis.

Uppsatsen handlar om hur de som intervjuats ser på mat och ätande. Viktiga avsnitt är, vad som är mat och inte mat.

The aim of this study was to evaluate the stir drying method, for drying of grain during Swedish conditions. The evaluation was done during the harvest year 2004, on four farms with stir driers. The driers were evaluated for their energy consumption, design, stirring effectiveness and how much time the farmer has to spend on every tonne of grain. A comparison was also done with conventional Swedish high temperature driers. Totaly six batches of grain from stir driers were examined, mostly winter wheat, but also barley and wheat.

In Sweden there are 1894 small-scale hydropower plants in operation, which together generate 4.3 TWh of electricity per year according to Swedish hydropower compound (SVKF, 2011). This corresponds to the annual consumption of about 860,000 Swedish households (based on an annual consumption of 5000 kWh). In the mid-1950s there were around 4000 small-scale hydropower plants in operation in Sweden before cheap fossil fuels and uranium competed with them, in the current situation only 1,894 of these are in use. If slumbering small hydropower plants once again would be taken into use and some new ones are built, we would be able to extract about 7 TWh of renewable electricity from these annually in Sweden, representing about 1.4 million households.The thesis intends to calculate and construct a hydroelectric power plant at the existing dam in Olofsfors and give suggestions on how the power station should run during the time that fish migration is greatest in Leduån.The turbine and generator to the station in Leduån at Olofsfors is designed by the height of the fall and the water flow through the dam. The turbine selected for the station is a CK-1000RM turbine with a 4-pole 250 kW generator from Cargo & power turbine Sweden AB, which is expected to deliver 1.2 GWh per year.

When implementing syncronous filters with global clock nets, a substantial amount of energy is consumed in the clock net. Hence, it is interesting to reduce the size of the clock net, which in turn will reduce the total energy consumption. One way to acheive this, is to create a SIC (Structured Interfacing of Computational elements) since such a structure can be created without a global clock net. Our results show that a fifth order wavedigital filter with a sample rate of at least 10M samples/sec may be achieved.

The main objective of this essay is to present the views of nine Swedish publishers and four other agents in the literary field regarding the possibilities of and obstacles to publishing fiction in an electronic format. Furthermore, whether or not electronic publishing is today actually a viable alternative. A substantial part of the essay functions as background to our interview findings and is based primarily on material originating from the Sociology of Literature field. The introductory chapter expounds the methodological and theoretical basis of the essay and is followed by a chapter placing our study in a larger, international media, context. Chapter three deals with the past decades? restructuring of the publishing sector, the professional functions involved in traditional publishing and Pierre Bourdieu?s theories on the cultural and economic forces at work in the literary field.

This bachelor thesis aims at investigate how a specified house can optimize its energy consumption.Today the house often stands for the major part of the energy consumption in a consumers? life,whereas an energy optimization creates economic as well as environmental advantages. It is importantto make old houses more energy efficient, but putting high energy demands on new houses could beargued to be more important. The installations functions as both the heart and brain in a house, thusmaking it important to energy optimize these. Since the background describes the importance ofenergy efficiency and optimization in a house, the focus area of this report will be an investigation ofdifferent types of heating systems in order to be able to choose the one most suited for the house.Aspects considered when choosing the heating system was how economic the system is both inservice- and investment costs and how environmental and operational friendly the system is.Through literature reviews there were sufficient information gathered that served as a foundation whencomparing and choosing between the four systems - district heating, pellet-fired boiler, geothermalheating and solar heating.

Aim: Nation Branding has become an important phenomenon during the last couple of years. The concept talks about how to promote a product by using the features of a nation to gain profit. Among the years many countries has established a strong Nation Brand abroad. In the long run many companies have chosen to use these benefits in an efficient way by promoting their own country brand, especially in their internationalization process. The aim of this study is to see what factors that influence companies in the Swedish food industry while using the fact that they are Swedish when they enter foreign markets. Method: Data was collected through interviews with export managers and sales managers at 6 Swedish companies exporting products within the food industry.

The world has changed its understanding of environmental issues dramatically and more people are showing awareness of social and environmental problems. Various stakeholders have increasingly begun to show an interest in how companies are taking responsibility for their actions. This has led to an improved activity amongst organizations to make their production consequences positive. They work with Corporate and Social Responsibility (CSR). In order to communicate their responsibilities, many companies work with CSR and ethical guidelines.

The purpose of this study is to examine what pupils in the ninth grade eats for lunch and also whether there is any connection between their lunch habits and perceived ability to concentrate and fatigue. A further aim was to study pupils' experience of dining environment in schools.The study is based on a quantitative method with questionnaires. The study was implemented on four schools in elementary school in themunicipalityofKristianstadand Tanum.Our results demonstrate, in accordance with several previous studies conducted in the same age group, that it is about half of the pupils who eats school lunch every day and that the majority are eating school lunch 3-5 days a week. Furthermore, our study shows that the pupils who rarely eat vegetables in school feel tired and distracted to a greater extent than the group of pupils who eat vegetables almost daily. Our result also shows that the group of pupils who eat the main course 3-5 days a week feel both tired and distracted to a greater extent than the group of students who eat the main course more rarely.In accordance with previous studies our study shows that differences exist between boys and girls regarding food that is eaten instead of school lunch.
