  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. Thermal physiology and metabolism : Interplay between heat generation and energy homeostasis

    Författare :Gustavo Abreu-Vieira; Jan Nedergaard; Eric Ravussin; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; fysiologi; Physiology;

    Sammanfattning : Mammal metabolism is intimately connected to the maintenance of body temperature. While metabolic pathways invariably produce heat as a by-product, the natural heat present in the environment also plays a role in defining the adaptive metabolism and general physiology of an organism.

  4. 3. Elucidating the molecular basis of Na+/H+ exchange

    Författare :Pascal F. Meier; David Drew; Simon Newstead; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; membrane protein; secondary-active transporter; Solute Carrier Transporter; ion-exchange; sodium proton exchanger; potassium proton exchanger; protein structure; cryo-EM; regulation; biokemi; Biochemistry;

    Sammanfattning : Solute carrier (SLC) transporters are membrane transport proteins, which catalyse the movement of nutrients, ions, and drugs across cell membranes. Here, I will present our contribution to understanding the mechanism of the sodium/proton exchangers (NHE), belonging to the SLC9 family of membrane transporters. LÄS MER

  5. 4. Miniaturized fluid system for high-pressure analytics

    Författare :Simon Södergren; Klas Hjort; Sami Franssila; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High-pressure; Microfluidics; Thermal regulation; Fluid mechanics; In-situ sensors; High-pressure analytics; Teknisk fysik med inriktning mot mikrosystemteknik; Engineering Science with specialization in Microsystems Technology;

    Sammanfattning : High-pressure chemistry can be used to determine the contents of blood or water samples and to discover new chemistries. However, working with chemistry at pressures of many tens, or even hundreds, of bars often requires expensive and stationary equipment, such as autoclaves or chromatographic systems like high-performance liquid chromatography (HPLC).

  7. 5. Thermal Modelling of Water-Based Floor Heating Systems - supply temperature optimisation and self-regulating effects

    Författare :Henrik Karlsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low temperature heating; self-regulation; predictive control; Floor heating;

    Sammanfattning : Low temperature water-based concrete embedded floor heating systems are studied. The utilisation of low quality heat sources is facilitated by low temperature heating. Theoretical models which describe the transient thermal floor heating operation constitute the basis for the analysis. LÄS MER
