Large volumes of excavated soil and rock are generated in building- and construction projects. These materials need to be transported longer and longer distances due to the densifications of cities. The transportation affects the environment in terms of noise and emissions, but also makes high demands on road infrastructure. To reduce the transport distances an increased responsibility for the excavated rock generated needs to be taken. Responsibility can be increased through an introduction of means of control.

Introduktion: Fosterdiagnostik med magnetkamerateknik (MR-teknik) har utvecklats mycket den senaste tiden och använts som en kompletterande metod till ultraljudsundersökning. Magnetkamera ger ingen joniserande strålning till patienterna, samt ger en mycket mer detaljerad bildinformation än vad andra metoder gör. I samband med MR kan de gravida kvinnorna uppleva olika psykiska påfrestningar genom både själva MR-undersökningen och oro för barnets hälsa. Även om MR-fosterdiagnostiken anses vara en säker undersökningsmetod för fostret föreligger det ändå en ovisshet angående de effekter som kan förekomma. Syfte: Syftet med examensarbetet är att genom publicerad forskning få kunskap som kan utveckla röntgensjuksköterskans möjlighet att ge optimalt stöd och information till gravida kvinnor vid fosterdiagnostik med MR-teknik utifrån följande aspekter: 1.

This is a graduate work at the Swedish University of Agricultural Sciences, The Department of Urban and Rural Development, Ultuna. The purpose of this paper has been to find out and describe principles for designing parks that offers good recreational and aesthetical values and require little amount of carbon dioxide emissions during their maintenance. The purpose has also been to see if it's possible to use city wastewater in some extent to assure the plants water supply and to find other means to make it less necessary to use purified water for watering. Recently made studies as well as older ones show how important green areas are in dense city structures both from a health and a climate perspective. Trees and other plants adsorbs different forms of air pollution and can also lower the temperature in the surrounding area through their transpiration.

The management of water resources and waste water varies between the countries of the EU. For many years, a large part of the water in Europe has been contaminated by, among other things, insufficiently treated waste water and emissions from agriculture. The EU Water Framework Directive 2000/60/EC and the Urban Waste Water Directive 91/271/EEC are intended to harmonize fresh-water management and waste water management within the whole EU, aiming at safeguarding drinking water of good quality and a high quality of all water within the EU today and in the future. There are however some problems concerning the waste-water directive. One problem is the huge investment needed in Slovakia to fulfil the demands of the waste-water directive for waste-water management in larger communities (with more than 2000 inhabitants).

Cnior Mobile AB i Lindesberg utvecklar en mobil trygghetstelefon för äldre. Detta examensarbete går ut på att utforma en handsfree-enhet för denna. Handsfree-enheten ska integreras i larmknappen, som bärs av användaren runt handleden, och har kontakt med telefonen via blåtandsradio. I examensarbetet ingår att välja ut lämplig högtalare och mikrofon, hitta lösningar för smuts- och vattentålighet samt att lösa problem med ekon och bakgrundsstörningar.En högtalare hittades som uppfyllde kraven för smuts- och vattentålighet samtidigt som den hade utmärkt frekvensgång för återgivning av tydligt tal. Vattenavrinning från högtalaren löstes genom att ett sinussvep sänds ut från högtalaren varje gång ett samtal ska kopplas upp.

This is a feasibility study that examines various aspects of building a wind farm on Malmön in Norrköping. The feasibility study deals with interests of conflict, park design, electrical connections, production calculation, financial calculations and operating- and timetable.The report is divided into two distinct parts. First a theoretical part, which deals with conflicting interests, park design and electrical connections. Second a part with simulations dealing with production calculations, and financial calculations.Opposing interests are mapped so that problem areas can be found, and help put focus on the right places at a future environmental impact assessment (EIA). There are a number of areas where planners have to assess on an EIA, this thesis point on the most important areas.

The goal of this master thesis project was to develop computer models of some plausiblepretreatment techniques and to assess the potential benefits/costs of using pretreatment andanaerobic digestion for waste management of organic waste from a system perspective. Forthis purpose a computer program called ORWARE has been used. ORWARE (organic wasteresearch) is a program for making life cycle assessments of waste management. As the mainpart of the project work the ORWARE system has been provided with three new models ofpretreatment techniques. The additions consist of: One model of pretreatment with ultrasound,one model of thermal hydrolysis and one model of a screw press.

I takt med att besökare och patienter ökar måste kontinuerligt Östra sjukhuset verksamhet utvecklas. Detta medför omläggningar i trafiken och förflyttningar av verksamheter. Idag finns flertalet brister kring Östra sjukhusets fysiska planering som behöver ses över, dessa är bland annat trafikflöden, säkerhetsaspekter och parkeringsmöjligheter.Rapporten redogör för förändringar i den fysiska planeringen som förbättrar dess utformning. Genom studier av relevant litteratur och diskussioner med expertis har förslag av problemområden tagits fram. Dessa har sedan bedömts efter listor av deras respektive för- och nackdelar som kunnat urskiljas.Arbetet visar framtagandet av ett väl fungerande förslag som kan verka som en bas för idéer till nutida och framtida förändringar kring den fysiska planeringen.

The Swedish Government has decided that Wind power should have a higher contribution to the electricity generation in Sweden. Their goal is that, by 2015, the yearly production by Wind power should generate 10 TWh. In year of 2006, the 760 wind mills in Sweden generated only 0,936 TWh. Despite good wind conditions in a large extend of Sweden's land- and coast areas, the slow rate of new wind mills establishments will likely result in unattainable goals. The major problem for new establishments of wind mills is the extensive and complicated permission process. An expert group of environmental studies (Expertgruppen för miljöstudier) was commissioned by the Government to make a report concerning the problems with the expansion of wind power in Sweden.

The foremost objective of business organizations is to generate value for shareholders and to opt for strategies which optimize it. Hence it is of key concern for business leaders to appreciate how operations best are run to maximize value creation. This study explores how financial theory can reveal the link between one particular business strategy and the corresponding effect on shareholder wealth. The question in focus is whether construction companies can enhance their value creation by implementing shift-work to increase the weekly production rate. The thesis particularly targets apartment block projects in Sweden and has the construction company Peab AB as primary object of study.

AbstractThis report intends through a case study to investigate if lightweight concrete isappropriate as main material in the outer wall of a seven storey residential building.A technical design is carried out in accordance with the definitions and requirementsfor passive houses, given by FEBY?s1 ?Demand specification for passive houses?.A literature review is also carried out for a comparison between regular bolt wall andlight weight concrete wall, with a focus on the safety of moisture.The lightweight concrete block used in the report is as a celblock produced by thecompany H+H Sweden AB.The methods used have resulted in compliance with requirements andrecommendations from authorities. Calculations of energy, noise and moisture riskassessment has been carried out.The work has resulted in the conclusion that the lightweight concrete itself is notable to isolate in the extent necessary to obtain chosen U-value of 0,1 W/m2 ° C,without getting to thick. Therefore additional insulation is needed. There are fewrelevant reference objects built with only light weight concrete.

I genomsnitt utsätts vi för 3000 reklambudskap under en dag, men bara cirka 14 % av de okonventionella kampanjerna har någon effekt. Vi har blivit för medvetna om hur reklam påverkar oss och för kritiska mot media för att köpa dessa budskap. Jay Conrad Levinsons grundade för cirka 30 år sedan begreppet gerilla marknadsföring. Den här kreativa marknadsföringsmetoden var till en början tänkt för de företag som hade begränsade resurser. Metoden kan vara väldigt kostnadseffektiv och används idag flitigt bland både stora som små företag.

Denna rapport behandlar ämnet magnetisk resonanstomografi (MR), och kan sägas vara en orientering i ämnet, då många av de inom MR förekommande begreppen behandlas och systemets grundfunktioner tas upp. Det finns mycket litteratur i ämnet och för den intresserade finns alla möjligheter att fördjupa sig, referenslistan längst bak i detta arbete kan tjäna som boktips och guide till att komma igång med vidare studier. Arbetet tar upp den fysik som ligger till grund för magnetisk resonanstomografi och begrepp som protonspinn, nettomagnetisering och relaxationstider gås igenom. Dessutom görs en genomgång av hårdvaran i MR systemet och de olika varianter av system som finns, det vill säga permanenta-, resistiva- och supraledande magneter. Detta arbete fäster störst vikt vid de supraledande magnetsystemen eftersom de är de klart dominerande kliniskt.

With the advance of the modern information society, the importance of reliable identity authentication has increased dramatically. Using biometrics as a means for verifying the identity of a person increases both the security and the convenience of the systems. By using yourself to verify your identity such risks as lost keys and misplaced passwords are removed and by virtue of this, convenience is also increased. The most mature and well-developed biometric technique is fingerprint recognition. Fingerprints are unique for each individual and they do not change over time, which is very desirable in this application.
