  1. 1. Development of strength and heat of hydration of young concrete at low temperature - influence of granulated blast furnace slag, silica and limestone

    Author : Monica Lundgren; Avdelningen för Byggnadsmaterial; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; låga temperaturer; värmeavgivning; betong; betonggjutning; hållfasthet; hydratation;

    Abstract : The work presented in this licentiate thesis was carried out within the project task Use of industrial by-products and filler in concrete, part Early-age strength development at low temperatures in concrete with mineral additions/fillers. To improve the understanding and to increase the data available, the study investigated the development of compressive strength and heat of hydration while curing at 5°C compared with curing at 20°C.

  2. 2. Avian thermoregulation across age and seasons

    Author : Fredrik Andreasson; Evolutionär ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ambient temperature; body temperature; Cyanistes caeruleus; energy expenditure; hypothermia; life-history theory; metabolic rate; Parus major; thermoregulation; trade-off; winter ecology;

    Abstract : Animals constantly need to relate to prevailing environmental conditions and regulate their body temperature accordingly. Body temperature regulation in birds and mammals is inherently linked to energy expenditure and, thus, thermoregulation is a physiological mechanism that could trade-off with other costly processes, with potential long-term fitness consequences.
