The purpose of this project is to analyze earthing systems for houses. By practical measurements and theoretical analyzes consequences of possible faults, that can occur within the facility and in the low-voltage distribution network, is illustrated.  The reason for this project is that nowadays one has to arrange with a main equipotential bonding system for buildings. Apart from that, if necessary, bathrooms must be provided with a supplementary equipotential bonding system.The practical measurements verify that potential differences in facilities may be due to voltage drops in the PEN conductor between the origin of the electrical installation and the power transformer.Based on the theoretical analyzes of possible faults, it is considered that the requirement for  supplementary equipotential bonding systems for bathrooms in most cases can be questioned, when basic insulation, fault protection, residual current devise and main equipotential bonding system already provides an adequate level of protection.A PEN conductor loss may result in a situation where metallic parts attached to the equipotential bonding system starts working as earth electrodes. Equipotential bonding system may also increase the incidence of stray currents. If TN-C-S systems is provided with a local connection to earth a redundant system against PEN conductor loss is obtained.

The thermal response of a borehole field is often described by non?dimensional response factors called gfunctions.The g?function was firstly generated as a numerical solution based on SBM (Superposition BoreholeModel). An analytical approach, the FLS (Finite Line Source), is also accepted for generating the g?function. In thiswork the potential to numerically produce g?functions is studied for circular borehole fields using the commercialsoftware COMSOL.

The purpose of this thesis has been to determine experimentally how good a peltierelement is to convert waste heat from wood burning. Three different peltier elementswere used in a comparison study. The comparison was mainly done to know howmuch power could be obtained from each element. Even, a circuit with a step-upfunction has been created to give a higher output voltage than the peltier elementitself. The result of the experiments was a low output power, the highest valuereached 2.18W.

Syftet med denna uppsats a?r att underso?ka pa? vilka sa?tt facklitteratur avsedd fo?r la?rare och la?rarstudenter i a?mnet svenska som andraspra?k reproducerar den koloniala skillnadsdiskursen. Jag har med sto?d i framfo?r allt postkolonial teori gjort en textanalys av en antologi inom a?mnet andraspra?ksforskning och funnit att den koloniala diskursen oavsiktligt reproduceras genom fo?rmedlingen av en statisk kultursyn, fo?renklande dikotomier och en assimilationsideologi. Min slutsats a?r att detta riskerar att fa? kontraproduktiva konsekvenser fo?r andraspra?ksundervisningen och att la?rare i svenska som andraspra?k beho?ver ett medvetet kritiskt fo?rha?llningssa?tt i sin hela fo?rsta?else av a?mnet. .

Water connects heaven and earth. Water is the most obvious element of nature. To move in water is for me more than cooling of on a hot summer?s day. It is about freedom and the feeling of being above the state of things.

The aim of the study is to examine how religion legitimates outrages and it what ways we can regard religion as politics. The study uses the theory that Eickelman and Piscatori present in their book Muslim politics. They use the term ?Muslim politics? to describe the relation between Islam and politics. Eickelman and Piscatori divide Muslim politics in five elements that the essay uses to structure the analysis.

Lättelement located in Örnskoldsvik AB is one of Sweden's leading companies in the development of building elements in the form of roofs, walls and floors made ??out of light beams. The company has clients from Lund to Kiruna, and from Norway. This means that the elements have high standards when they have to take many different loads from wind and snow due to such wide geographic variation.The roof elements are structured so that the main body is made of light beams with an I?profile.

Studiens syfte a?r att ta del av fo?rskolla?rares tankar om vad som ha?nder na?r en ny potentiell resurs kommer in i fo?rskolan. iPad a?r na?got som nyligen gjort intra?de i fo?rskolan och det a?r iPad som potentiell resurs som denna studie handlar om. Vi har gjort kvalitativa intervjuer med sju fo?rskolla?rare som alla pa? na?got sa?tt jobbar med iPads i sin verksamhet.

By using industrialized building, pre-installed modules can be delivered to the construction site where they are easily mounted. This method has many advantages compared to on-site manufacturing, for example, the precision during the production process should be much higher than building each wall and floor on site. Furthermore, the quick erection procedure when using prefabricated elements and the possibility to use weather protection has the advantage of not being dependent on weather conditions, and many other factors.Masonite Beams AB is a Swedish company (a member of the Norwegian company, Byggma ASA) with a relatively new technology using light weight beams as bearing elements in the walls and a certain stiff board lamella slap which is mounted on the top of the floor structure creating an integrated stiff beam / board floor structure. The elements are flat which make it much easier to transport the elements from the factory to the building site where the building parts are easily mounted with special mounting stud.One of the main drawbacks of lightweight structure is the sound transmission. The main topic is low frequency annoyance, however the complex structural elements and their mutual sensitive connections other acoustical problems might appear.

Syftet med denna studie ?r att unders?ka kommunikationen mellan l?rare och v?rdnadshavare p? en m?ngkulturell skola och hur l?rarna uppfattar att detta p?verkar eleverna. Detta kommer att unders?kas utifr?n ?tta h?gstadiel?rares perspektiv som, i kontrast till v?rdnadshavare, kommunicerar och har kontakt med flera v?rdnadshavare samt har en bredare ?verblick ?ver eleverna. Syftet konkretiseras genom f?ljande fr?gest?llningar: 1. Vilka m?jligheter och hinder finns i kommunikationen mellan l?rare och v?rdnadshavare p? en m?ngkulturell skola? 2. Hur uppfattar l?rarna att detta p?verkar eleverna? F?r att besvara fr?gest?llningen genomf?rdes en kvalitativ unders?kning d?r ?tta h?gstadiel?rare som arbetar p? en m?ngkulturell skola blev intervjuade individuellt. Dessa intervjuer spelades in, transkriberades och d?refter kategoriserades med hj?lp av en tematisk analysmetod som var i linje med studiens ?vergripande syfte.

Lattelement AB in Ornskoldsvik is one of the leading companies in Sweden in composite elements in walls, floors and roofs in particular. The company supplies elements to buildings located with a wide geographical variation, which means that the products are subjected to very different climate with regard to snow, wind and humidity. This places high demands and requires the elements to withstand large variable loads.The elements are made of lightweight beams with flanges of structural timber and beam webs made of OSB. These are bound together by nogging pieces with the same kind of structure. On top of the beams a nailed and glued plywood is added to absorb compressive forces and on the underside of the element a sheet of steel is added for tensile absorption.These elements are then attached to the building framework in different ways depending on the particular element height, loads and the structual supporting material of the frame work.
