  1. 1. 231Pa and Th isotopes as tracers of deep water ventilation and scavenging in the Mediterranean Sea

    Author : Sandra Gdaniec; Carl-MAgnus Mörth; Per Andersson; Helen Coxall; Per Roos; Carl-Magnus Mörth; Per Anerson; Matthieu Roy-Barman; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; 231Pa; 230Th; 232Th; Mediterranean Sea; scavenging; deep water ventilation; geokemi; Geochemistry; Protactinium; Thorium; particle transport; deep water circulation;

    Abstract : The naturally occurring isotopes 231Pa and 230Th are used as tracers of marine biogeochemical processes. They are both produced from the radioactive decay of their uniformly distributed uranium parents (235U and 234U) in seawater. READ MORE

  2. 2. Multi-year maintenance optimisation for paved public roads - segment based modelling and price-directive decomposition

    Author : Per-Åke Andersson; Per Olov Lindberg; Torbjörn Larsson; Jonathan Bard; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; road maintenance optimisation; price-directive decomposition; Optimization; systems theory; Optimeringslära; systemteori;

    Abstract : I avhandlingen studeras hur kostnadseffektiva underhålls- (uh-)planer för belagd väg kan genereras, på basis av information om aktuellt vägytetillstånd och funktionella modeller för kostnads- och tillståndsförändringar, delvis utvecklade i samarbete med svenska Vägverket (VV). Tilltänkt användning är på strategisk och programnivå, innan mer detaljerad objektinformation finns att tillgå. READ MORE
