Avfallshantering på byggarbetsplatser : Potential för en miljöeffektiv avfallshantering

This thesis concerns waste management on construction sites and was conducted on behalf of ICA Fastigheter.Areas of concern:How can an environmentally-efficient waste management system on construction sites be defined? What potential exists for exploiting the waste resources that are generated?How can the waste management be optimised by reducing the quantity of waste and by optimal sorting?How can the client of a project influence the waste management?The purpose of the work was to investigate sustainable waste management in the building and construction sector and to highlight waste as a resource from an environmental and economic perspective.The aim of the work was to define an environmentally-efficient waste management system, to analyse the potential that exists in waste management and to draw up guidelines for optimal waste management.The method consisted of a literature study, two visits to construction sites and four interviews.An environmentally-efficient waste management system means that the waste is managed in the following order of priority:Prevention     Reuse  Recycling     Energy recoveryLandfill     The prevention of waste is an important area that has not been adequately explored by the building and construction industry. The quantities of waste could decrease with the implementation of measures such as ordering materials in the dimensions required, prefabricated components, logistics centres with Just-In-Time deliveries, less and improved packaging and less wrapping. The reuse of waste materials and temporary apparatus as well as the use of a return pallet system are examples of reuse that reduces the quantities of waste.In most cases the source sorting work is a matter of course and the proportion going to landfill is down at a low level. The source sorting can be optimised by sorting all materials that can be reused and recycled to use them as a resource.

Rostfärgat slam i dränagesystem vid vattenkraftsanläggningar : orsaker och åtgärder

From embankment dams is something that has long been noticed and given rise to different questions. The most serious question is if the sludge is a result of inner erosion through the dam, and thus consists of material transported from the dam. Concerns have also been raised whether the sludge could interfere with the systems drainage capacity and thereby lead to high pore pressure in the dam, or if the measurement of seepage is disturbed, as the measuring is usually made via Thomson weirs, which could risk being blocked. The result of this investigation shows that the sludge is a result of the oxidation of iron by iron bacteria, and to the greater part consists of these oxides as well as the bacteria?s own structures. The iron oxidizing bacteria, FeOB, oxides ferrous iron to ferric as a part of their metabolism, and thereby create large quantities of iron(oxy)hydroxides.

Valutasäkringsstrategier En kartläggning av svenska företag inom industribranschen på Mid Cap och Large Cap

I den här uppsatsen kartläggs operationella valutasäkringsstrategier i svenska företag. Företagen återfinns inom industribranschen på Large Cap och Mid Cap på Stockholmsbörsen.För att få en generell kunskap om valutasäkringsstrategier hölls initiala intervjuer med dels Magnus Jarlén, Corporate Finance Director på AB Volvo, dels Peter Karlsson, Head of Treasury på AB Volvo. Förutom att bidra till bakgrundskunskap, utmynnade även intervjuerna i en problemdiskussion utifrån vilken frågeställningar skapades.Uppsatsen ämnar besvara hur valutasäkringsstrategier ser ut i de gällande företagen, samt om finanskrisen 2008 har haft någon påverkan och i så fall hur den påverkat valutasäkringsstrategierna. Uppsatsen ämnar även undersöka om det finns riktlinjer för hur valutasäkringsstrategier skapas. Slutligen undersöks varför vissa företag säkrar sin valutaexponering med derivatinstrument medan vissa företag väljer att inte göra det.Som underlag för att besvara frågeställningarna har en litteraturstudie gjorts tillsammans med granskningar av tidigare svenska och utländska undersökningar inom valutahanteringsområdet.

Kopplingen mellan Livscykelkostnader och Building Information Modelling

Detta examensarbete har undersökt vilka möjligheter som skapas genom att använda BuildingInformation Modelling (BIM) för Livscykelkostnadsanalyser (LCCA). Arbetet beskriver förstLCCA och sedan hur BIM samt öppna standardiserade dataformat kan användas för LCCAoch för kvalitetssäkring av data. Till sist visas hur ett verktyg som räknar ut LCC direkt frånen byggnadsmodell kan utformas. Genom att kunna synliggöra konsekvenserna av olikalösningsalternativ och göra kvalitativa LCCA erhålls genomtänkta lösningar och medvetenhetom de framtida förvaltningskostnaderna. För en byggherre som också ansvarar för driften kandessa alternativsvärderingar och analyser leda till betydligt lägre förvaltningskostnader.

We've both said things you're going to regret : En undersökning av dagspressens framställning av TV-och datorspel perioden 1995 till 2012

The use of computer and video games has increased immensely over the past few decades and today a majority of the Swedish population enjoys them on a daily basis. With such a large number of frequent users, the media reporting on the subject of games becomes interesting and important. How are games represented in the media, and has there been any change in the way they are portrayed as their popularity has grown? ­The aim of this study is to determine if and how the portrayal of computer and video games in Swedish newspapers has changed during the period 1995?2012. The study was conducted with the use of quantitative content analysis and the empirical data was collected from the two most widespread newspapers in Sweden ? DN and Aftonbladet.

The report is the result of a research of a building project, constructed by Peab. The report is investigating and it means to identify and evaluate qualities in the dwelling and its surroundings. Its purpose is to evaluate how the residents in a chosen housing cooperative enjoy living there. It shall, with help of chosen quality aspects, identify what expectations the residents had before moving in, how they experience the dwelling and its surroundings today, and what hopes they have for the future planning of the area.

Effektiv lagerstyrning genom tillförlitlig prognostisering : Effective inventory control through reliable forecasting

This study was done regarding whether sealing or ventilation is the best solution to prevent moisture on cold attics. The authors of this report addressed the problem with moisture in attics when they started their cooperation with Peab.The methods included interviews with people, database research, and calculations of a project in Akersberga north of Stockholm. The conclusion is based on interviews and other information as they are analyzed in relation to the house of reference. The focus of this report is on problems with moisture in the attics known as cold attics.The background of the problem with moisture is that today?s slabs are usually insulated to save energy and that the attics nearly gives the climate as the outdoor climate.

Utländska biblioteket i Karlskrona 1835?1864 : om högreståndskvinnors organisation och läsning

This master's thesis studies Utländska biblioteket, a 19th century foreign literature subscription library in Karlskrona, Sweden. The aim of the thesis is to investigate Utländska biblioteket between 1835?1864.The material consists primarily of primary sources from the archive of Utländska biblioteket. The main primary sources are the library's accounts book, its minutes, and two book catalogs. Using analytical tools from Jürgen Habermas, feminist criticism of his ideas and from Pierre Bourdieu, as well as results from previous research on older library forms and female organization in the 19th century, the thesis answers questions relating to the library as a society, its members and its book collection.The investigation shows that Utländska biblioteket was a subscription library as well as a book circle.

Resultat av tjugofem års mätningar av Cs-137-halter i älg i Uppsala län

At the end of April 1986 reactor number 4 of the nuclear power plant at Chernobyl explod-ed and large amounts of radioactive particles were then released into the atmosphere due to both the explosion as well as the consecutive fire of the graphite core. A cloud of radioac-tivity was spread over the northern hemisphere, including Sweden, due to the prevailing wind directions. The radioactive particles were washed out from the cloud by rain and snowfall in some areas of Sweden and deposited on the ground. The deposited radionu-clides, primarily cesium and iodine isotopes, were later absorbed into the soil and taken up by the roots of the plants. Some of these radionuclides, like 137Cs, still persist in some of the terrestrial ecosystems at relatively high concentrations which lead to contamination of the meat of moose, roe deer and wild boar even today.The two municipalities Heby and Uppsala, in the eastern part of central Sweden, experi-enced a relatively large deposition of 137Cs which resulted in high levels of 137Cs in moose and other game.

Transformatordiagnostik genom dissolverad gasanalys

The transformer is one of the most common and most important electric machines for power companies. Cost of investment and the economic worth of a transformer are counted in millions of SEK. Because of that, proper maintenance actions that may lead to longer technical life time should be the aim in all situations.The aim with the report was to perform transformer diagnosis by dissolved gas analysis on Umeå Energi AB´s power transformers and a risk assessment. The report should also contribute to longer life time for the transformers.Oil samples were taken from each transformer two times. The first sample in summer 2013 and the second in April 2014.

Momentbärförmåga för semikompakta ståltvärsnitt av HSQ-balkar : En modell för interpolering mellan eurokodens klass 2 och 3

The current standards for design of steel beams are divided into four classes based on the slenderness of cross-sectional parts. Depending on the section class a beams load capacity is either determined by a plastic, elastic or a reduced elastic model. The division between cross-sections calculated by a plastic and an elastic model is today done in a very harsh way with no smooth transition. This leads to a large difference in the calculated resistance for the sections located near the class limits. Elasto-plastic sections are in the current situation calculated as purely elastic and their large plastic reserve is not considered in the current standards.
