    University essay from Medie- och Informationsteknik; Tekniska högskolan

    Author : Julia Ander; [2013]
    Keywords : Beläggningsåtgärder; korsning; spårbundenhet; spårbildning; ABS11; Densiphalt; PMA; PMS Objekt.;

    Abstract : Korsningar, busshållplatser, söderbackar och lastkajer är ytor med extrem påkänning på grund av hög trafikbelastning, låg hastighet, accelerationer, inbromsningar, svängningar, spårbundenhet och utsatthet för höga temperaturer. Den speciella lastsituationen riskerar orsaka spårbildning, vilket är det vanligaste problemet i korsningar. READ MORE

  4. 38. Fracture resistance of porcelain-veneered gold-alloy and zirconia molar crowns

    University essay from Malmö högskola/Odontologiska fakulteten (OD)

    Author : Eddie Nilsson; Marko Drazic; [2013]
    Keywords : Crowns; Dental Stress Analysis; Dental Veneers; Materials Testing; Metal Ceramic Alloys; Zirconium;

    Abstract : AbstraktSyfte:Studiens syfte var att utreda maxlasttoleransen mellan yttria-stabiliserad zirkoniumdioxid- (Y-TZP) och metallkeramiska- (MC) molarkronor med en ny design på in vitro belastningsformen. En stålkula användes för att utöva last på kusparna istället för i fissuren för att framställa en sprickbildning liknande den som ses kliniskt. READ MORE

  5. 39. Hydrogen uptake during Carburizing and Effusion of Hydrogen at Room Temperature and during Tempering

    University essay from KTH/Materialvetenskap

    Author : Maryam Khodahami; [2013]
    Keywords : hydrogen; case hardening; gas carburizing; tempering; hydrogen embrittlement; hydrogen diffusion;

    Abstract : The carburizing atmosphere during the case hardening process contains a large proportion of hydrogen. Due to the rapid diffusion of hydrogen a high amount of hydrogen can be absorbed by the carburizing component. The amount of absorbed hydrogen is dependent on some factors such as for example the carburizing time and component dimensions. READ MORE

  6. 40. Effect of microfibrillar cellulose on concrete equivalent mortar  fresh and hardened properties
