Energieffektiv torkning av kläder : en studie av torktumlare med varm- respektive kallvattenanslutning

Tumble dryers and drying cabinets have to a large extent replaced the traditional way of drying clothes outdoors. They are faster, more convenient, require less space and can be operated regardless of weather conditions. This replacement has significantly increased residential energy consumption, due to the fact that tumbles dryers consume large amounts of electrical energy. In the USA 9 % of the households electric energy is consumed when drying clothes. Over 4 million tumble dryers are sold in Europe each year and 20 % of the residential Electricity consumption in Sweden is used drying and washing clothes.

OTEC för Tarawa

Ocean Thermal Energy Conversion, OTEC, a technology using the temperature difference between cold deep seawater and warm surface water, can extract the work in the form of electricity. OTEC gives also synergies of drinkable fresh water. The temperature difference has an impact on the efficiency of the technology, which means that the feasibility of OTEC is geographically limited. The project intends to explore the possibility of replacing the atoll Tarawa?s present electricity generation with an OTEC plant and to explore synergies. In the present situation all of Tarawa?s electricity is generated by fossil fuels.

Energikonsumtion hos en diskmaskin

The dishwasher is a wide spread product that occurs in many households. It saves the user time,water and energy. When using a dishwasher instead of doing dishes by hand a lot of energy issaved.The importance of lowering the energy consumption does not only come from the consumerwinnings but also from an environmental point of view. Scientists are certain that the globalwarming comes from the emission of green house gasses that is created by human consumptionof oil, gas and coal.Dishwashers today are a lot more energy efficient than older dishwashers, but there are stillmargins to lower the energy consumption. The aim with this project is to investigate thedishwasher and it?s washing cycle, noting different phases and components that contribute towaste of energy.

Flickor ? identitet ? alkohol : en kvalitativ undersökning på Maria Ungdom om flickors identitetsskapande i relation till problematisk alkoholkonsumtion, ur ett behandlarperspektiv

The objective of this study was investigating social worker?s perspective of how alcohol consumption can affect, and what elements in the social environment that may be of significance for, alcohol consumption and development of identity. The questions at issue were: Do social workers experience any positive effects from alcohol consumption in 16-17 year-old girls with problematic alcohol consumption and what influence do the effects have on self esteem, self image and development of identity? What do social workers experience are the negative effects from alcohol consumption on self esteem, self image and development of identity? How important do social workers find the social environment and how do they believe the social environment affect the alcohol consumption and development of identity? This was investigated with a qualitative approach from a social worker?s perspective, hence social workers were interviewed. The study?s theoretical basis was Symbolic Interactionism and Erikson?s theory of Psychosocial Development.

Utveckling av Innovativa Småskaliga Elförsörjningskoncept : - Minor Field Study i Namibia

A large part of the Namibian low income population lack access to grid distributed electricity. This mean they are effectively shut out from basic functions such as lighting, information technologies and hygienic food handling. Hence, finding ways of providing affordable off-grid electricity is an important, not to say critical, task.This master thesis is an innovation and concept development project that has been carried out in cooperation with organisations in Sweden and Namibia. The purpose of the project has been to (1) develop a concept for off-grid electricity supply in Namibia and (2) to gain a deeper knowledge within the area of innovation and product development for the Base of the Pyramid population, i.e. the poorest, but largest, socio-economic part of the global population.Essential in this project has been to acquire user understanding and to identify user needs to create a foundation for developing the concept.

Skogsmaskiners bränsleförbrukning :

This report is a thesis work for a B.Sc. in Forestry exam at the School for Forest Engineers, SLU. The aim of the work was to compare fuel consumption during work in practical field conditions with a standardized method developed by Skogforsk (The Forestry Research Institute of Sweden), (Brunberg, 2005) for harvesters and forwarders from different manufacturers and of different sizes in order to promote the development of more fuel efficient machines. Two studies were carried out. - Statistics of fuel consumption were collected. - An inquiry was sent out in order to get more detailed information of different aspects influencing the fuel consumption. The studied machines were divided into two classes, large machines (> 150 kW), and average size machines (100 ? 150 kW), and of the manufacturer Timberjack and Valmet. Our results shows a 15 % lower fuel consumption for average size harvesters and an 8 % higher fuel consumption for large harvesters compared with Skogforsks model.
