Högeffektslysdioder. Möjligheter och förutsättningar för högeffektslysdioder som belysningskälla - ett demonstrationsbygge

This report examines the prerequisites for LEDs to replace other technologies indifferent applications. How does the different technologies for light generationwork and what are the advantages and disadvantages? The various technologieslimitations and characteristics provides the opportunities for the LEDs.This report describes a test-construction built to examine what practical arrangementscan be built with modern light emitting diodes, in order to showsome of the possibilities. The construction consists of three different applications,a high power lamp based on cold white LEDs, one based on warm whiteLEDs for the evaluation of the light characteristics and a RGB-LED based lampable to mix any colors quickly and seamlessly. The test construction also containsthe essential peripherals including control-electronics, optics and a custombuilt watercooling solution.The potential for LEDs is huge but it is complicated to Build LED based applicationsdue to the limitations which mainly includes the electronics and theneccesary cooling.

Sverigedemokraterna i kommunerna 2006 ? En empirisk studie av de kommunala förhållanden som gynnar partiet

The Sweden Democrats achieved great progress in the latest election in the Swedish municipals. The party is now closer than ever concerning reaching the Swedish parliament. This thesis examines the Sweden Democrats in the Swedish municipals with the aim to find out which municipal factors that led to their progress. By looking at the percentage share of unemployment, the percentage share of foreigners, the percentage share of education, average income, traditional political colour, average age, criminality, early representation of a party hostile to foreigners, the municipal type and the sickliness in the municipals I find out which factors explain the progress of the Sweden Democrats. The thesis is an empirical quantitative study Build on statistics by the help of regression analysis and diagrams.

Lufttäta byggnader

The viscosity of air Buildings is a hot topic within the construction performers, which the industry feel they have too little knowledge about. This study is mainly aimed against air density in apartment Buildings and airflow measurement. The study consists of a theoretical reference, educational visit, interviews and a survey conducted among construction workers at Magistratshagen in Linkoping.Earlier requirement in terms of air leakage through the climate screen was removed and today there are only energy requirement for a dwelling in Boverkets Building Regulations. The difference between a passive and a typical air tight construction is that the passive house have a maximum requirement of 0.3 l /s m2 of air leakage through the Building climate screen. The requirement imposed on passive houses is to minimize the supply of power and energy for heating the Building.Air tight constructions have heavy demands on the performance and accuracy of everyone involved with the project. The client must specify their requirements and also be prepared to pay for any additional costs. The architect and Building planners have to design the Building with regard to air tightness. Finally, the construction workers are required to do a careful work in order to get all the connections in the Building air tight.The study suggests that an air tight Building is a closed system where no forced ventilation exists. There are no reasons not to Build too tight as long as there is a functioning ventilation. In this study the authors ask themselves how an air tight Building changes over time. No theoretical information has been found on these changes, but the respondents assume that air density decreases with time. The deterioration is mainly assumed to be caused by construction materials changes over time. The study shows that construction workers knowledge of air tight construction is mixed, which they themselves admit in the survey..

Solmodul jord- och bergvärmepump

An increasing number of heat pump producers have developed heat pumps that can be connected to solar panels. In this thesis we have examined the possibilities of connecting solar panels to existing ground source- and geothermal heat pumps that has not been adapted to solar panels. During the work process, a prototype plant has been built to compare our theory with the practical results and with our designed sizing tool. The work has rendered in knowledge that will be used to Build a sun module that can be easily connect to the existing heat pump system. The existing heat pump, our test plant, has been supplemented by an advanced storage tank used to allow different operating modes.

Att främja barns delaktighet: En studie av barnbibliotekariers syn på barns delaktighet i folkbibliotekets barnverksamheter

The objective of this thesis is to explore the prerequisites for children?s participation in the activities of the public library as expressed by six children?s librarians. Qualitative semi-structured interviews were carried out to investigate how the librarians interpreted the concept of participation and viewed power issues between children and adults. Further, difficulties and possibilities experienced in working with children?s participation and manifestations of children?s participation in everyday library work were also investigated.

Produktionskalkyler för biobränslen :

This study is one of five that has been done based on Lunds Energi?s planned investment in bioenergy. The plan is to Build two large burners, at Örtofta, that?s going to be supplied with biofuels. In this study I take a closer look on the profitability when you choose to sell your cereal as bioenergy. I?ve been calculating with selling the straw from the grain crops and winter rape, selling the rye weat as whole crop and fertilize the hemp with sewage sludge.

Laserinkopplingselement För XFEL Laser Heater : Från Idé Till Färdig Produkt I Designstadie

Uppsala University is involved in a large international collaborationto Build the Laser heater system for the European Xray Free-electronlaser in Hamburg, Germany. In this thesis I describe a laser incouplingdevice into the vacuum chamber of this laser heater all the way fromthe specifications to a completed design.The laser heater is a very important part of the XFEL and thepart described here is a part of the vacuum system needed to couplean external laser into the electron vacuum system and align it withthe electron bunches in order to heat them. The task was started by studying the literature about the basic theory andthe design of vacuum systems. After this study and collection of ideaswith colleagues I started to prepare different concepts to solve thetask. The ideas can be put into two categories, in one case the couplingmirror is located inside the vacuum chamber and in the second caseoutside.

Det är bara ett litet stick. Nålfobi hos ungdomar och vuxna : En litteraturöversikt

Background Adolescents and adults suffering from needle phobia have an unreasonable fear of needles that leads to negative experiences if they do not get the support they need. Negative experiences lead to patients avoiding health care, or these experiences affect important aspects of life. The suffering that a patient experiences may be obvious to some, but others hide it, and then it will be more difficult to detect. The nurse's role is to recognize the suffering and its different reactions in order to alleviate and prevent unnecessary suffering of the patient. AimThe purpose of this study was to describe about young people's and adults' experiences of having needle phobias.

Hur hållbar är serogrisproduktion? :

Raising pigs in absence of a number of certain diseases is called Seroproduction in Sweden. Internationally it?s called SPF (Specific Pathogen Free) ? Production. It results in higher growth, lower feed consumption, and lower medicine consumption. The pigs are produced under the same concept, but the rules vary a bit between countries.

Have resultade in regulations.

Beröringens makt : En litteraturöversikt om hur vårdpersonal använder sig av beröring i omvårdnaden

Background: Human interaction by touch plays a central role for our health and well being throughout life. When people touch each other our bodies release a hormone called oxytocin into the bloodstream, this gives the body a soothing effect. Touching on the other hand can be perceived as unpleasant if it is not in accordance with the patient?s norm or wishes. From biblical times and through to today human touch plays a central part of nursing.

Vill du prata?

Today's consumers are demanding more and more from companies and are no longer as easy to im-press as they used to be. It is now the consumers that hold an increasing amount of power over com-panies and not the other way around. This change in consumer behaviour has caused an identity crisis for traditional advertising, and companies are now searching for new ways of reaching their target audience. The purpose of this combined qualitative and quantitative case study is to examine possible risks and possibilities that a retailing company face when communicating through Facebook. Data has been collected through in-depth interviews with company representatives combined with a quantitative study of the company's Facebook followers in order to answer the questions of (1) which possibilities and risks a retailing company face through the use of a Facebook fanpage and (2) if there is a differ-ence in the attitude and behaviour of active respectively passive followers that may have been caused by a retailing company's marketing communication on Facebook.
