  2. 1. Cooling and dopamine

    Author : Roger Roscher; Anestesiologi och intensivvård; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology; electrophysiology; cooling; Hypothermia; swine; lung transplantation; organ preservation; dopamine; circulation; contractility; oxygenation; intensive care; Anestesiologi; intensivvård;

    Abstract : There is little knowledge about the circulatory effects of dopamine in hypothermia. Induced hypothermia has been shown to improve outcome in various settings. Hypothermia is also used for preservation of organs that are harvested for transplantation. READ MORE

  4. 2. Urban Climate and Air Pollution in Ouagadougou, Burkina Faso

    Author : Jenny Lindén; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sub-Saharan Africa; Sahel; semi arid; nocturnal cooling; urban vegetation; evening evaporative cooling; cooling rate; atmospheric stability; thermal wind; carbon monoxide; particulate matter; road dust; exposure differences;

    Abstract : ABSTRACT Africa has recently been singled out by UN Habitat as the fastest urbanizing continent in the world. The most extreme case was found in the Sahelian city of Ouagadougou, Burkina Faso, where the population is expected to almost double over the next ten years. READ MORE

  5. 3. Direct-Ground Cooling Systems for Office Buildings: Design and Control Considerations

    Author : Taha Arghand; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Borehole; Cooling capacity; Laboratory experiments; Ground heat exchanger; Fluid temperature levels; Control; Direct-ground cooling; Optimization; High temperature cooling;

    Abstract : Direct-ground cooling systems are defined as systems in which the ground is used as the only source for cooling mainly in commercial buildings. These systems benefit from exchanging heat with the ground, of which its temperature is basically constant below a certain depth year around. READ MORE

  6. 4. District Cooling – Towards Improved Substation Performance

    Author : Maria Jangsten; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; control strategy; heat exchanger; district cooling; HVAC; operational data; energy transfer station; substation; low delta-T; high temperature district cooling;

    Abstract : The global cooling demand in buildings is rapidly increasing and to supply this demand, district cooling is one solution. However, many district cooling systems suffer from low delta-Ts (receiving low return temperatures from the buildings connected to the system). READ MORE

  7. 5. Modelling of Jet impingement Heat Transfer for Cooling of Cylindrical Foods

    Author : Eva Olsson; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multiple jets; Nusselt number; cooling; sinle jet; Jet impingement heat transfer; CFD; cylinder; SST; food;

    Abstract : Cooling is an energy consuming operation in the food industry. Rapid cooling reduces the risk of growth of micro-organisms, improves the quality of the food product and increase the production rate... READ MORE
