1. 1. Streams, Steams, and Steels : A Transnational History of Risk Regulation in Nuclear Power Plants (1850–1985)

   Författare :Siegfried Evens; Per Högselius; Kati Lindström; Anna Storm; Scott Knowles; KTH; []
   Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; Nuclear; risk; water; steam; steel; regulation; safety; Nucléaire; risque; eau; vapeur; acier; sûreté; réglementation; Kärnkraft; risk; vatten; ånga; stål; säkerhet; History of Science; Technology and Environment; Historiska studier av teknik; vetenskap och miljö;

   Sammanfattning : Water is essential to produce nuclear energy and prevent nuclear disasters. As light water reactors are increasingly seen as a solution to achieving a sustainable energy transition and battling the climate crisis, it is more important than ever to investigate the risks of using water for nuclear power production.

3. 2. Orangerier : orangerier vid vallonbruk i Uppland

   Författare :Jan G. Holmberg; Jadwiga Krupinska; Torbjörn Jilar; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; orangeries; 18th century Sweden; Walloon furnaces; farden history; horticulture; Architecture; Arkitektur; History subjects; Historieämnen;

   Sammanfattning : The purpose of this thesis is to describe and analyse the reception and development of the orangery in the county of Uppland, Sweden, during the 18th century. A main obstacle for the gardeners and their governors must have been the local climate in Uppland, a county at the south border of Norrland, the very north part of Sweden. LÄS MER

4. 3. Thermal adaptation along a latitudinal gradient in damselflies

   Författare :Viktor Nilsson-Örtman; Frank Johansson; Karl Gotthard; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Growth rate; metabolic theory of ecology; universal temperature dependence; environmental gradients; thermal performance; thermal sensitivity; environmental variability; optimality theory; life history; acclimation; size structure; competition; cannibalism; intraguild predation;

   Sammanfattning : Understanding how temperature affects biological systems is a central question in ecology and evolutionary biology. Anthropogenic climate change adds urgency to this topic, as the demise or success of species under climate change is expected to depend on how temperature affects important aspects of organismal performance, such as growth, development, survival and reproduction.

5. 4. Studies in pest control for cultural property

   Författare :Thomas Strang; Göteborgs universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; Pest control; cultural property collections; insect; mould; environment; integrated pest management; IPM; thermal control; pest risk to museum collections;

   Sammanfattning : This thesis considers discrete problems of protecting cultural property from pests and examines some of the solutions. Recent decades have seen a large change in how fumigants and pesticides are used in collections of cultural property. LÄS MER

7. 5. Thermal history of the Phanerozoic sedimentary succession of Skåne, southern Sweden, and implications for applied geology

   Författare :Ingela Olsson; Berggrundsgeologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mineralogy; geochemistry; Petrologi; mineralogi; geokemi; Petrology; organic matter reflectance; organic geochemistry; illite crystallinity; clay mineralogy; thermal history; Phanerozoicum; Skåne; Sweden;

   Sammanfattning : Post-depositional thermal conditions have been investigated throughout the Phanerozoic sedimentary succession in Skåne. Clay mineralogy and illite crystallinity have been the main tools for the Lower Palaeozoic strata. Within the Mesozoic sequence thermal influence was examined using RockEval pyrolysis and vitrinite reflectance analysis. LÄS MER
