Under detta projekt har vi tittat på hur man kan återladda en bergvärmekonfiguration med lågtempererade solfångare. Projektet utfördes åt Newsec Energy i Stockholm vars kund samfälligheten Ängsbacken ville minska andelen tillskottsenergi som utgörs av olja till sin bergvärmeanläggning. En utredning av anläggningen gjordes av Newsec Energy som visade att berget kylts ned och att anläggningens borrhål varit underdimensionerade. Vi fick uppdraget att utveckla en systemlösning med lågtempererade solfångare..

ABSTRACT: Commercial swab transport systems are used for collection and transporting of fecal and other microbiological samples. This system must maintain viability and contribute to survival of microorganisms during transport to the laboratory. Four swab transport systems have been compared, eSwab, ?- Transwab and fecalSwab, all three with flocked swabs, and Copan Venturi Transystem with rayon swabs. The study followed the recommendations from the Clinical Laboratory Standard Institute; document M40-A for recovery of Samonella, Shigella, Yersinia and Neisseria gonorrhoeae after storage for 0, 6, 24, 48 and 72 h at room- (22-25°C) and refrigerated (2-8ºC) temperature.

Examensarbetet utfördes på Atlas Copco Rock Drills och det gick ut på att uppdatera en borrenhet med Rig Control System. Det är ett datastyrt hydrauliksystem som möjliggör automatisk borrning. För att få automatisk borrning behöver borrmaskinens position mätas med hög noggrannhet och en lösning kunde presenteras som uppfyller det kravet. Projektet startade med att ta fram olika förslag i form av koncept som sedan utvärderades med personal från Atlas Copco. Resultatet blev ett förslag som sedan vidareutvecklades och kompletterades med produktionsritningar och strukturer..

In order to avoid harmful substances ending up at the municipal sewage treatment plants, it is important to purify the wastewater at the source. One such source is the wheel washers available in many tire garages which are used to wash the wheels on our vehicles when we change between summer and winter tires. It is important to wash the wheels before storage, to extend the tires lifetime. The purpose of this study is to find a green innovative solution for reduction of emissions of heavy metals at the source, so that the sludge from the sewage treatment plants can be used as fertilizer. The target is to find a wheel wash method which leads to compliance with the guidelines for car washers, and that also provides a better washing result than with the existing method.

Landfill leachate contains a variety of contaminants and is created when rainwater percolates the landfill. For landfill management the leachate is the main issue that can cause problems to the environment. At the landfill of Fläskebo, Renova AB treats the leachate in a local treatment plant. The treatment consists of a chemical treatment step with chemical precipitation, flocculation, sedimentation and filtration, and a final step with a carbon and peat filter. Renova has to ensure that the condition of the leachate reaches the regulation set for the landfill before it is released to the recipient.

The culture center studied has gone from being organized by enthusiasts and ideals, to being institutionalized with a educational association responsible for the management. The questions discussed are ? how this change affects the active people in the house and what consequences these changes make for the institution of the house and for the regular management..

Abstract Co-operation difficulties in the work place can be a problem serious enough. Co-operation difficulties can occur between employee and employer, as well as employees among themselves. Irrespective of between which individuals the co-operation difficulties occur, it will have negative consequences. These can consist of, for example that individuals might suffer mentally, inproductivity and also an unwished economic disadvantage for the employer. From the employers? side it is pointed out that it is important with employees who are possible to co-operate with in a satisfactory way.

This is a degree project performed at Halmstad University in Sweden on the subject carpet ofreinforcement. This project is developed in association with Celsa Steel Service in Halmstad.The purpose of this report is to investigate how much time that can be saved if carpet ofreinforcement is used instead of the traditional way to work with reinforcement and seewhat kind of parameters that is important between the choices. We are also going to seehow this product affects the situation for reinforcement workers from an ergonomic point ofview.Carpet of reinforcement is made by straight reinforcement?s bars that are welded togetherwith steel bands. These rolls are made at a factory with a machine that welds together thebars in determined centre distance, with desired dimensions after the constructionengineers? blueprints.

Detta examensarbete har gjorts i syfte att få fram förankringslängder till ett bergförankrat vindkraftverk.Målet med examensarbetet har varit att få fram längder på förankringstag och en prövning av flera olika stagvarianter har gjorts.Det dimensionerande momentet och egentyngden på vindkraftverket har tagits från ett tidigare projekt beläget i Solberg. Dessa krafter har fördelats ut till stagen och förankringslängder har tagits fram. De delar som har hanterats i rapporten utöver dimensioneringen är stagvarianter, borrning av stag, injekteringsbruk och provdragning. En bottenplatta i form av en oktogon har använts i dimensioneringsprocessen. Stagen har placerats i en cirkulär form i ett lager.

Med dagens stora utbud av festivaler och det nya festivallandskapet som har va?xt fram de senaste a?ren finns det na?got fo?r alla som a?r intresserade. Syftet a?r att med hja?lp av kvalitativa intervjuer fo?rso?ka definiera vad det a?r som go?r en festival intressant fo?r vissa och helt ointressant fo?r andra och hur detta kan kopplas samman med Bourdieus teori om habitus.

In search of Umbilicaria subglabra In Sweden Umbilicaria subglabra has its only known occurrence in Lybergsgnupens nature reserve in the county of Dalarna where it has been found only once in 1936. It was found on the east-facing rock spur, approximately 650 meters above sea-level. The lichen is now red-listed as Regionally Extinct (RE) in Sweden. The aim of this study was find U. subglabra.

I was assigned to the thesis as part of a project GMA AB (Ground Machinery Applications AB) is running. The project aims to develop a new method for injection of drilled holes in rock walls. Currently, the injections usually involve cement but the basic idea of the project is to replace cement with a supplement called Silica sol.Silica sol is known as a gelling liquid. The gel time is controlled by a mixing of saline. Depending on the amount saline that gets mixed in, the gel time varies.

My intention with this study is to evaluate, as a singer and a voice teacher, a number of routines for daily vocal practice through practical application. Seven different routines are presented, five of them originating from interviews with Swedish vocal teachers and singers and two chosen from literature. These routines are then tried out and evaluated. Using the results of these evaluations as a basis, I make an attempt at formulating my own personal practice routine, optimal for my own needs. I will also try to address motivational issues related to practice with hints acquired through the interviews.

The subject singing in elementary school changed its name to music in 1955 and with the name change followed a change in the content of the topic. In my study, I examine the perspective of how song as a subjekt has changed in the basic school curriculum texts. As a complement to text analysis, I used interviews in which two music teachers with long service in primary school were interviewed. My survey shows that there has been a clear change of the contents of concept song from being a pure skill where the aim was the vocal line benefits in different contexts and is today a vocal expression that can be embodied in many different ways. Curriculum texts have not been crucial to the changing content of the concept song.

The industrialization in Sweden has increased the large number of areas that have been contaminated with various types of pollution. One of those sites are the property Höjen 3:24 in Arboga where ?Arboga Mekaniska Verkstad? once been. The property wants to increase the use of the old former foundry building with the adjacent ?plate-workshop? and believe there are two options for the building: That the building either should be used as a warehouse/concert hall, or rebuilt into a cultural center. An environmental evaluation has shown that the levels of heavy metals are over the Swedish environmental protection agency guidelines of less sensitive land.
