Stommaterial för villor - trä eller betong?

We have the tradition in Sweden to build villas and houses with a wooden framework. It has become natural for us because we have so much forest in our country. Building with wood has advantages, it is easy to process, but also disadvantages, as it is sensitive to moisture.Finland has long made use of the thermal blocks to build villas. It is a type of bricks that are a bit like a sandwich element, with a core of EPS and concrete on both sides of the core material. The concrete is hollow, so that after the walls has been bricked up you pour concrete into the hollow bricks.The issue of this report is to find out if concrete can be an alternative to wood as framework material in villas.

Integritetsstudie av Ceph : En mjukvarubaserad lagringsplattform

Dagens moderna organisationer driver vanligtvis en kostsam IT-baserad infrastruktur. De besitter högpresterande funktionalitet och säkerhet för att garantera att de dagliga operationerna fortskrider. Mjukvarubaserade lagringsplattformar är ett alternativ som kan användas för att reducera dessa kostnader. Genom att efterlikna avancerad teknik som redan existerar i traditionella lagringsplattformar kan detta implementeras som mjukvara på commodity hardware i syfte att uppnå samma funktionalitet. Ceph är ett alternativ som numera implementeras och ämnar erbjuda detta val.

Småskalig säsongslagring av solenergi för uppvärmning av bostäder : Simulering av lagerutformning och konsekvensen av adderade uppvärmningsbehov motsvarande en pool och ett atrium

The sun is a huge energy source with great potential of providing energy to the heating of homes and other buildings in an environmentally sustainable manner. In order to provide buildings with energy from the sun it is necessary to transfer the energy supply over time to when the demand arises. By storing the heat in a seasonal storage, solar energy from the summer can be used in the winter when the demand for heating is greatest.Today's existing plants are mainly in Europe and particularly in Germany. These facilities are designed to supply heat demands greater than 400 MWh and covers about 40-50 % of this need which consists of energy for space heating and domestic hot water. How much of the heat demand that is covered, the solar fraction, is partly due to losses from the storage which in turn is connected to the surface area of the storage.

Fred ? till vilket pris? ? En studie om etiken kring kärnvapeninnehav

This bachelor thesis focuses on the ethics concerning the possession of nuclear weapons seen from a deontological and utilitarian perspective. I have also considered the aspects of International law, the Just-war Theory, and Michael Walzer's Legalist Paradigm. The research question that guides my essay is: Is it possible to ethically justify a country's possession of nuclear arms, which results in direct and indirect threats against other countries?I have chosen to focus my essay on the period of 1945 to 1990, also referred to as the Cold War. I find the bipolar system that existed between the USA and the Soviet Union as a good empirical example, during which the nuclear arms debate constantly took place.The result that my thesis brings is rather ambiguous.

Nya trädgårdsväxter för ett allt varmare Sverige

The aim with this work has been to examine the climate changes and what these has meant, and will mean during the present century, for plants that have not been hardy in Sweden. A lot of new species can probably be grown today in Sweden's most southern parts, due to an increase in the average annual temperature by 1?C. There is a need of information about these new species and their hardiness. The insufficient information about the subject has been the background to this work.

Vitvarueffektivisering med hjälp av värmelagring : Simuleringsstudie kring energiförsörjning av vitvaror med hjälp av värmepump & ackumulatortank

The constant need of energy is something that affects us all no matter our current situation. Whether we are driving our car to work, taking the elevator or using the oven to cook dinner we end up relying on energy. Our whole society is continuously striving to achieve a higher grade of efficiency and the process of supplying ourselves with energy is no exception. The importance of appliances in our everyday life cannot be exaggerated and thus the importance of their high efficiency.Efficiency is already a keyword in the appliance industry with labels, stars and numbers helping us choosing the most suitable option for the task ahead. No matter how efficient appliances often use pure electricity as their energy source.

FN och terrorism : En studie av världssamfundets policy sedan kalla krigets slut

The United Nations has a responsibility to combat acts of international terrorism, as they constitute a threat to international peace and security. In spite of this, there exists no generally accepted definition of the phenomenom within the UN. By examining resolutions on terrorism, this thesis aims to evaluate the UN?s policy on terrorism since the end of the cold war until 2003. The results show that the UN?s attitude towards terrorism eversince the end of the cold war has been condemning, but that the the events of September 11th 2001 has contributed to an even more firm approach to the problem.

USA och FN- samarbete eller konflikt

AbstractUniversity of Växjö, School of Social SciencesCourse: PO 5363, Political Science 41-60Title: US and UN, cooperation or conflict?Author: Charlotta BjuvlingSupervisor: Lennart BergfeldtDate: Autumn 2007The international society changed a great deal after the end of the cold war. It gave the United Nations a new oppertunity to act after the deadlock during the war, and it gave the United States a new hegemone role in the world politics. The aim of this paper is to investigate wheter the United States foreign policy action have been accordence to a realistic way of thinking since the end of the cold war. I will do this with the help of my research questions:? Have the United States followed the guidelines of the United Nations in their foreign policy?? Are there signs that show of a change, either towards more or less cooperation between United Nations and the United States?To answer these questions I will use the theories realism and Hedley Bulls concepts of fairness and his ideas of an international system in his book ?An Anarchical Society?.

Häckar för Norrland

I have observed that hedges are not as prevalent in gardens in the north of Sweden as in the south despite a number of beneficial qualities attached to their use. Consequently, the primary purpose of this essay is to examine the potential for the use of ligneous or woody plants as hedges in a cold climate. The aim of this study is to provide information about the various varieties of ligneous plants that can be used for both pruned and unclipped hedges in the north of Sweden. Because the hardiness of the ligneous plants is a vital factor here, only plants that are hardy enough to survive in the Swedish hardiness zones V to VIII are included in this study. Roses, dwarf shrubs, conifers, bushes with a final height of less than 1 metre and plants that ?bleed? have been excluded.

Den svenska neutralitetsdebatten 1988-1992

Starting at the end of the Cold War, this publication assesses the impact of the upheavals in Eastern Europe and the atrophic Soviet Union on the Swedish doctrine of neutrality with its 200 year old tradition. Since the end of world war two the proximity of the Soviet Union had constituted the major impetus for upholding a position of neutrality and as this vanished a pressure for change was created. This essay works with a theoretical framework delineated by Kjell Goldmann and under this disposition, the Swedish tradition of neutrality, governmental positions, opposition and four major influential newspapers are studied. The standings of each variable are canvassed in an attempt to explain the development of Swedish security policy during the crucial years of 1988-1992..

Pre-treatment of grain for ethanol production during storage

Ethanol for automotive purposes is an issue much debated and researchers disagree about the benefits of bioethanol. Converting energy-rich crops into ethanol suitable as motor fuel is a complex process and continuous development and improvements of processes and material used are important steps in the work of developing environmental friendly fuels. Grain is usually preserved by drying which consumes a lot of energy. Alternative storage of high-moisture grain in airtight storage systems reduce the energy required to produce bioethanol and studies have also shown that ethanol yields are increased more than 10% in ethanol fermentations of moist grain compared to dry. Airtight storage is often not perfectly airtight so biocontrol agents are necessary in order to preserve the grain.

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.

Skötsam

The project has been performed in a close collaboration with Hörsam who works in the field of hearing technology. In a first meeting with the company, the Project group was showed a few existing storage boxes for hearing aids. The company thought they were unnecessarily large with plenty of unused space and wanted a new, smarter solution to be developed.The project began with user studies in which audiologists, maintenance technicians, future users and others were interviewed. The purpose was to obtain their views on today's storage boxes and to find out how well the users maintained their hearing aids. It proved to be a large lack of knowledge regarding the management of hearing aids within the users.
