  1. 1. Role of GPIbαlpha Clustering and N-linked Carbohydrates in the Clearance of Refrigerated Platelets

    Författare :Emma Josefsson; Göteborgs universitet; []
    Nyckelord :Platelets; GPIbalpha; alphaMbeta2; phagocytosis; refrigerated platelets;

    Sammanfattning : The thesis focuses on understanding the mechanisms by which: 1) the macrophage alphaM-subunit recognizes betaN-acetylglucosamine (betaGlcNAc) residues on the von Willebrand factor receptor complex ((GPIbalpha,beta/IX)2V or vWfR) on refrigerated platelets and 2) refrigeration changes vWfR to elicit recognition through alphaMbeta2. Until recently, the only well-established mechanisms affecting platelet survival were antibody-mediated platelet clearance, consumption of platelets by coagulation reactions, and loss due to massive bleeding.

  3. 2. 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

  4. 3. Supermarket refrigeration systems for demand response in smart grids

    Författare :Tommie Månsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Supermarket; Demand-side management; Smart-Grid; Energy efficiency; Food retail; Demandresponse; Thermal modelling; Refrigerated Display Cabinet; Renewable energy;

    Sammanfattning : With an increasing share of intermittent renewable energy sources in the electrical grid, the need for adapting the demand to the available supply of electricity becomes increasingly important. Within this thesis, the demand response capacity by supermarket refrigeration systems are investigated and methods for enabling it is developed. LÄS MER

  5. 4. Exploring barriers to energy efficiency in supermarkets

    Författare :Ulla Lindberg; MariAnne Karlsson; Högskolan i Borås; []
    Nyckelord :retail; servicescape; foodscape; chilled groceries; energy efficiency; barriers; refrigerated display cabinets; consumer behaviors; consumer perceptions; Resource Recovery; Resursåtervinning;

    Sammanfattning : Energy efficiency activities in sections of grocery stores for chilled groceries are subject to particular challenges as this is a complex indoor environment given that the goal of store owners is to offer consumers chilled groceries of high quality in a comfortable environment while at the same time trying to reduce energy use. Consequently, it is important to maintain the right temperature in the right place and to be aware of the consumers’ shopping situation. LÄS MER

  7. 5. Dual roles for hepatic lectin receptors in the clearance of chilled platelets

    Författare :Viktoria Rumjantseva; Göteborgs universitet; []
    Nyckelord :platelet storage; Asialoglycoprotein receptor; GPIbα; αMβ2; transfusion; clearance;

    Sammanfattning : Platelets for transfusion are stored at room temperature because refrigerated platelets are cleared rapidly from circulation. Room temperature storage causes major inconveniences for blood banks and medical risks for recipients. LÄS MER
