Malmmineralogisk undersökning av Pb-, Zn-, Cu- och Ag-förande kvartsgångar i Värmskogsområdet, mellersta Värmland

AbstractPolymetallic (Pb-Zn-Cu-Ag-Au-Sb-As-Bi-Cd-Te-Se-Ge?) quartz veins occur in an area from Eidsvoll in southeastern Norway to west of LakeVänern in southwestern Sweden. They most likely formed during the waning stage of the c. 1 Ga Sveconorwegian orogeny. In Värmskog parish, Värmland county, several mineralized quartz veins of different types are known.

Test bench for air bearingsThis thesis work consisted of bringing forward and defining the test parameters relevant for a test bench and constructing a test bench that can test and verify the largest existing air bearings that are of use in Micronic Laser Systems AB machines. Because the knowledge about air bearings is limited it is thought that with the help of the test bench the knowledge would increase and in that way improve the air bearings.After learning more about air bearings and their purpose at Micronic Laser Systems AB, I started the concept phase for the test bench. For each part in the test bench I consulted my two tutors, Torbjörn Hedevärn and Johan Bergqvist, at Micronic Laser Systems AB. The final concepts where documented as 3D-modells in Solidworks and some of them have been tested in Solidworks FEM-program.The test bench is designed so that, with the help of a pneumatic cylinder, 25 kilo weights are placed on the air bearing to test its stiffness, damping and the pressure performance under its surface area. To test these parameters the test bench has to have a pressure meter, accelerometer and a microcator.

Klarspråk och malltexter : En studie om klarspråk och malltexter för att främja läsbarhet i beslutsbreven från Stadsbyggnadsförvaltningen i Eskilstuna kommun

I denna studie studeras klarspråk och malltexter i tre beslutsbrev om överklagan av kontrollavgift från Stadsbyggnadsförvaltningen i Eskilstuna kommun. Syftet med studien är att främja läsbarheten för mottagarna och att förenkla och kvalitetssäkra klarspråksarbetet i Eskilstuna kommun genom att förändra beslutsbrevens utformning.De metoder som använts är textanalys i form av en läsbarhetsanalys och Klarspråkstestet och en kvalitativ intervju med en handläggare på Stadsbyggnadsförvaltningen. Med textanalyserna har jag undersökt hur de befintliga breven är utformade utifrån begreppen klarspråk och läsbarhet. Genom intervjun kunde jag undersöka hur en handläggare på Stadsbyggnadsförvaltningen arbetar med beslutsbreven och hur hen resonerade kring språkanvändning när beslutsbreven skrivs.Utifrån mitt resultat och gällande riktlinjer och principer för klarspråk har jag skapat tre nya beslutsbrev. Beslutsbreven har utformats efter mottagarens behov vilket lett till en förändrad stil i tilltal, disposition, ordval, meningar och rubriksättning för ökad begriplighet.

Rostfria stålkonstruktioner och rostskyddsbehandling av stålkonstruktioner enligt Eurocode

Steel is an excellent material to build with, but consideration must be given to the fact that unprotected steel corrodes, rusts, therefore, as a rule, the steel must be protected in some way. This can be done by reducing the tendency of the steel to corrode by using stainless steel or by treating the steel with a protection method. The two most common methods of protection are corrosion protection paint and zinc coating. To determine the method, the corrosive category must first be evaluated and this is done in accordance to EN ISO 12944-2:1998.Stainless steel is available in many varieties but only some of them have properties that make them suitable for use as construction steels. There are many factors to be considered in the design of stainless steel to prevent corrosion from occurring.

Bygga hus i traditionell härjedalsstil

The purpose of this degree-project was to investigate the possibilities for primary air preheating into the two smallest waste incineration boilers of Halmstad Energy and Environment. The investigation is a pre-study which has the primary goal to evaluate technical and financial offers from companies that manufacture primary air preheater, and investigate if it is technically and financially profitable to do a purchase on primary air preheaters in the future.In the pre-study it is proposed that it is most efficient to have individual primary air preheater, one for each incineration boiler and the primary air are also proposed to be preheated by hot water in the pre-study. Further in the pre-study it is proposed that the heat-exchanger should have plain tubes instead of finned tubes, to avoid getting dirty fast. The space in the boiler-room is limited, and therefore the major problem was to fit in the primary air preheaters into the boiler-room. By comparing the different offers from the companies, the result in the pre-study shows that the offer from the company C.A.

Möjligheter för naturturism i Borgsjö

Increased interest in nature tourism may be what saves small and dying villages, like Borgsjo? in the county of Va?sterbotten in northern Sweden, from disappearing. The nearly untouched nature in these areas is in many cases an unused resource, since true wildlife experiences are sought by many travelers. The purpose with this report is to investigate if Borgsjo? has the potential and abilities to become a destination for nature tourists, and how this should be done to avoid negative effects on nature, wildlife and culture.

Utvärdering av radiologiska kriterier för att bedöma tillståndet ileus på hund :

Dogs presenting with vomiting and abdominal pain, are common patients at the small animal clinic, and the reason for these symptoms can have various aetiologies. One common reason for these symptoms is obstruction of the small intestine caused by a foreign body. Obstruction of the small intestine is best diagnosed by using radiography, contrast-study if needed, and ultrasound. To avoid further examinations, diagnosis from plain radiographs is preferable. One of the signs of illness one can detect from these examinations is a dilation of the small intestine proximal of the obstruction, caused by gas or fluid; ileus.

Järnvägsstationer i Litauen 1861-2011 : Namngivare, namnbyten och språkbyten genom 150 år

The names of railway stations and halts along the earliest railway lines on Lithuanian territory have been studied, i.e. along those railway lines built between 1861 and 1873. Especially, attention has been drawn to names that are not obvious regarding the geographical location of the station or halt. Some 50 percent of the names are showing some kind of irregularity in this respect. Most common (about 30 examples) are stations or halts that are serving a population centre situated at some distance from the station, but still bearing the name of that population centre.

De uteblivna möjligheterna? intressegruppers diskursiva hållning vid en stadsomvandling

Although being recognized as holding great cultural-historical significance by local officials, numerous parts of the functionalistic development along Friggagatan became demolished in 2008.This bachelor thesis have surveyed how the planning process proceeded through various municipal committees, and moreover, how different interest groups gathered around certain discursive attitudes. As a consequence of various paradigm shifts in society, e.g. that local government gradually are depending on private economic initiatives, there are to some extent a fear among politicians that cultural-historical demands can risk economic growth.Nevertheless, a building or a development are in fact bearing different value-perspectives, such as economic, functional and cultural-historical. Due to the fact that the heritage-sector has limited resources, in combination with sometimes vaguely and obsolete conservation documents, the sector have difficulties of responding common economic arguments, which leads that the real estate-owner gets total interpretative prerogative.However, despite a sometimes suspicious political attitude towards an improved conservation document, e.g. with continuously updates concerning a building?s technical and economic status, there are some political initiatives working towards it..
