Politiskt utanförskap : en studie av invandrarsammansättning, kommunorganisation och kommunpolitikers demokratisyn som förklaringsfaktorer av underrepresentation av invandrare.

The development that the Swedish society has experienced during the last four decades and the higher part of the population coming from foreign countries calls for a more intensive research on the situation of these groups. The purpose of this study is to find explanations of the differences in the share of immigrant politicians in Linköping and Norrköping. The starting point of the study is a model of factors assumed to affect the representation of immigrants in the municipality assemblies. The immigrant composition, the municipality organization and the view of democracy of the politicians, are all assumed to affect the civic participation. The civic participation is then assumed to affect the representation of immigrants in the municipality.

Lövsuccessioner i sluttningar längs nedre Umeälven :

Secondary deciduous forests, which have their origin in earlier pasture- and meadow-land in slopes along the lower reaches of the Ume river, are thought to contain high nature conservation values, in spite of a relatively low age. The aim of this study was to clarify how factors as historical use, exposition, disturbance dynamics and successional age influences the conservation values in these types of riparian forests and how this can be implicated in the practical work with conservation and management at Umeå municipality. Sample plots were placed in seven stands with a variation of their historical use, exposition, disturbance dynamics and age of succession. Conservation values as structure, tree-regeneration, abundance and composition of vascular plants, amount of dead wood and the abundance of signal-species were measured and registered. The species composition and especially the composition of tree species, differed between forests with different exposition and different historical use.

Georg Stubendorff, organist i S:t Jakob : En musiker i stormaktstidens Stockholm och hans concerto "O Jesu dulcissime"

AbstractJan Johansson: Georg Stubendorff, organist i S:t Jakob ? En musiker i stormaktstidens Stockholm och hans concerto "O Jesu dulcissime", [Georg Stubendorff, Organ Player in S:t Jacob's Church ? A Musician in Seventeenth Century Stockholm and his Concerto O Jesu dulcissime], Uppsala universitet, Institutionen för musikvetenskap, uppsats för 60 p, 2006.Georg Stubendorff, organ player in S:t Jakob's church in Stockholm 1663-1672, was one of the very competent foreign musicians that came to work in Sweden in the 17th century. The purpose of this essay is to contribute to the knowledge about him and about the conditions in general for church musicians in Stockholm during that era, and to present an edition of his Concerto a 3. It is shown that Stubendorff may have come to Stockholm from Livland, rather than Germany as earlier accepted. The Concerto a 3 is the only composition by Stubendorff that has survived (now in the Düben collection at Uppsala university library).

Storjuktan ? Rekonstruktion av ett sekels kvicksilverbelastning. : En undersökning av kvicksilverkoncentrationer i daterat bottensediment.

The aim of this study was to examine the current and historic mercury(Hg) load of the lake Storjuktan due to its recent exposure to a local potential source of Hg in form of the Sulphide mine Blaikengruvan(2006) and an earlier potential sources of Hg-load, the damming of the lake(1960s). Sediments were extracted using a HTH-sampler, freeze-dried, and analyzed for tot-Hg, LOI and activity of 210Pb and compared to samples extracted prior to the opening of the mine(2006). Constant initial concentration (CIC)-dating model was used for dating the samples. Low levels of Hg (100ng/g) were found throughout the lakes sediment. The highest levels of Hg(220ng/g) was detected at a depth of 4-5cm dating back to the mid 1970:s, suggesting that increased levels of atmospheric Hg rather than damming of the lake has caused the increase of Hg.

Ett re(el)lt hot? Om elprisets betydelse för investeringar inom basindustrin

The aim of this thesis is to investigate the correlation between the price of electric power and investments within the Swedish basic industry. Using regression analysis, the authors test for correlation between the electricity prices and the basic industry, defined as the pulp and paper industry, the mining industry, the steel and metal industry and the basic chemical industry. Moreover, five variables found in the literature on investment decisions are being used as a means of comparison. The results suggest that the electricity price affects the investment decisions within the basic chemical industry as well as the steel and metal industry. On a more abstract level, this thesis contributes to the understanding of one of the properties of the Swedish GDP..

Parameterstudie av inneslutningsbildning och utvärdering av processföring för tillverkning av plastformsstål

This thesis has been performed at Uddeholms AB with the purpose to investigate theparameters affecting the formation of inclusions during the manufacturing of a low carbonmanganese-steel.A follow-up, steel and slag sampling and evaluations in microscope have been done for a totalof five heats.The results for each heat have been evaluated in relation to the theory from the literaturesurvey and suggestions for changes in the process to reduce the amount of inclusions whichhave a negative effect on the steel quality have been given.The project extends over a large process where many parameters affect the formation ofinclusions. However, a tendency that a higher addition of alloys seems to increase the totalamount of inclusions before and after the vacuum degassing is seen.The majority of the studied inclusions seem to approach the composition of the top slag aftervacuum degassing. Ladle glaze may cause the inclusions which had a different compositioncompared to that of the slag.A high or low ladleage together with a high argon flow during vacuum degassing seems todissolve particles from the refractory which later on get trapped inside the inclusions.The floatation for two heats has been studied where a short floatation seems to give a higheramount of inclusions in casted material.In machined material so called stringers were found. The main composition of those stringerswas pure alumina. Inclusions with a composition of pure alumina were not found in the liquidsteel, thus the pure alumina inclusions must be formed during the casting.

Miljö i fokus - En studie av de bakomliggande drivkrafterna för den ökade miljömedvetenheten inom svensk kemiindustri

BACKGROUND & During the last century, the Swedish chemical industry has developedPROBLEM: considerably in regard to respecting the environment. Following various discharges and pollutions during the first half of the 20th century, environmental concepts such as CSR, Responsible Care and REACH have developed in order to improve the situation. Today, environmental issues play a central role in the society, but what are the reasons behind this increased environmental commitment? PURPOSE & The purpose of this thesis paper is to study the driving forces behindDELIMITATIONS: the increased environmental awareness in companies. Is this mainly due to stricter legislations, or do factors like pressure from the general public, the industry or customers play a more vital role? Furthermore, do economic incentives exist, that make it interesting for companies to invest in environmental awareness? Since the chemical industry spans over a wide spectrum in regard to environmental issues, this paper will focus on a specific area of the industry.

Optimering av den kemiska reningen vid Fläskebo deponi

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.
