Optimization of freeze-thaw durability testing for low-carbon concrete with VPI
(Master thesis; Mastergradsoppgave, 2024-06-04)Concrete, the most widely used building material, significantly impacts the environment, with cement production contributing up to 8% of global CO2 emissions. To address this, low-carbon concrete (LCC) mixes with supplementary cementitious materials (SCMs) have been developed. Fly ash (FA) is a well-established SCM, but with the decline of coal-fired power plants, alternatives like volcanic pozzolans ... -
Kardiorespiratorisk form og risiko for hjerneslag blant kvinner og menn. Tromsøundersøkelsen 1994-2021
(Master thesis; Mastergradsoppgave, 2024-05-29)Bakgrunn: Hjerneslag er en av de ledende dødsårsakene i verden. Tidligere forskning har vist at kardiorespiratorisk form (KRF) kan være en prediktiv faktor for hjerte- og karsykdommer. Dette kan være en viktig faktor for den generelle folkehelsen i Norge og på verdensbasis. Det er derimot lite forskning som ser på den spesifikke sammenhengen mellom KRF og hjerneslag, spesielt blant kvinner. Hensikt: ... -
