  1. 1. From behaviour to genes: anti-predator responses of brown trout (Salmo trutta) under winter conditions

    Författare :Karl Filipsson; Eva Bergman; Ann Erlandsson; Martin Österling; Johan Watz; Stefán Óli Steingrímsson; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; burbot; climate change; cortisol; diel behaviour; gene expression; HPI axis; light; mRNA; piscivorous; poikilotherm; predator; salmonid; stream; stress; temperature; thermal; winter behaviour; Biology; Biologi;

    Sammanfattning : Temperature has major effects on the performance of poikilotherms. In encounters with predators, low winter temperatures constrain predator detection and escape capabilities in prey fishes. LÄS MER

  3. 2. Prediction of power and energy use in dwellings : Addressing apects of thermal mass and occupant behaviour

    Författare :Victor Fransson; Avdelningen för Installations- och klimatiseringslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggnadssimulering; Termisk massa; Värmetröghet; boendes beteende; hushållsel; varmvatten; building simulation; thermal mass; thermal inertia; occupant behaviour; household electricity; domestic hot water;

    Sammanfattning : Households are responsible for approximately 26 % of the annual energy use in the EU. Following the EU-directives regarding energy performance in buildings, international initiatives have been taken in Europe to help countries to define and include guidelines in their own building codes, for example, to establish the concept of zero energy buildings, ZEBs.

  4. 3. Thermo-Mechanical Behaviour of Refrigerated Caverns in Hard Rock

    Författare :Rune Glamheden; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; thermal deformation; rock caverns; igneous rocks; thermal properties; underground storage; low temperatures; refrigeration; thermal strain;

    Sammanfattning : For almost 4 decades, underground caverns in hard rock have been used to store liquefied petroleum gases (LPG) and refrigerated products, such as foods and chemicals. The design of such facilities has, however, been founded on relatively limited knowledge of the reaction of rock masses to cooling. LÄS MER

  5. 4. Thermal response test : method development and evaluation

    Författare :Signhild Gehlin; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Sammanfattning : Since the first introduction of thermal response tests with mobile measurement devices in Sweden and USA in 1995, the method has developed and spread in North America and Europe. Thermal response tests have so far been used primarily for in situ determination of design data for BHE (borehole heat exchanger) systems, but also for evaluation of grout material, heat exchanger types and groundwater effects.

  7. 5. Functional Performance of Gadolinium Zirconate/Yttria Stabilized Zirconia Multi-Layered Thermal Barrier Coatings

    Författare :Satyapal Mahade; Per Nylén; Nicolaie Markocsan; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Erosion; Gadolinium Zirconate; Suspension Plasma Spray; Thermal Barrier Coatings; Thermal Cyclic Test; Thermal Conductivity; Yttria Stabilized Zirconia; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : Yttria stabilized zirconia (YSZ) is the state of the art ceramic top coat material used for TBC applications. The desire to achieve a higher engine efficiency of agas turbine engine by increasing the turbine inlet temperature has pushed YSZ toits upper limit. LÄS MER
