  1. 1. Insulation materials in district heating pipes : Environmental and thermal performance of polyethylene terephthalate and polyurethane foam

    Author : Sara Mangs; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; HFC-365mfc; insulation; District heating pipe; 3-pentafluorobutane; cyclopentane; 3; 1; mass transport; 1; 1; thermal performance; polyurethane foam; polyethylene terephthtalate foam;

    Abstract : District heating can contribute to increased energy efficiency in society. The environmental impact can be reduced by minimising the heat losses in the district heating pipes during distribution of the heat to the customers. READ MORE

  2. 2. Predicting the Long-Term Insulation Performance of District Heating Pipes

    Author : Camilla Persson; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heat conduction; polyurethane foam; insulation capacity; diffusion; thermal conductivity; cyclopentane; solubility coefficient; long-term performance;

    Abstract : The aim of the studies that comprise this thesis was to predict the heat loss over timefrom a range of district heating pipes insulated with closed-cells foam. The thermalconductivity of the foam changes over time when it is not diffusion-tight encapsulatedagainst the environment, as diffusion alters the cell gas composition until it reachesequilibrium with the surrounding air.

    Abstract : This thesis describes the design, synthesis and structure-activity relationships analysis of potential inhibitors targeting the hepatitis C virus (HCV) NS3 protease. Also discussed is the disease caused by HCV infection and the class of enzymes known as proteases. READ MORE

  4. 4. Design & Synthesis of Protein Interacting Affinity Ligands and Protease Inhibitors

    University dissertation from Stockholm : Department of Organic Chemistry, Stockholm University

    Author : Charlotta Lindquist; Stockholms universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Chemistry Organic chemistry Organic synthesis; NATURVETENSKAP Kemi Organisk kemi Organisk syntes; organisk kemi; Organic Chemistry;

    Abstract : There is a growing need of both protein drugs and synthetic drugs in the fight against many life-threatening diseases. The first part of this thesis deals with the design and synthesis of high affinity binding ligands for the purification of protein drugs. READ MORE

  5. 5. Waste Heat Recovery in Heavy Duty Diesel Engines

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Jelmer Johannes Rijpkema; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Organic Flash Cycle; Heavy Duty Diesel Engine; Organic Rankine Cycle; Trilateral Flash Cycle; Transcritical Rankine Cycle; Internal Combustion Engines; Waste Heat Recovery;

    Abstract : Over 50% of the energy released by burning fuel in a truck engine is lost as heat rather than being used to propel the vehicle. A promising method for capturing and reusing this heat, and thereby improving engine efficiency, is to exploit thermodynamic cycles for waste heat recovery (WHR). READ MORE
