  1. 1. Chloride transport and chloride threshold values studies on concretes and mortars with Portland cement and limestone blended cement

    Detta är en avhandling från Lund : Division of Building Materials, Lund University

    Författare :Dimitrios Boubitsas; RISE.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cement; Mortar; Concrete; Corrosion; Reinforcement; Chloride ions;

    Sammanfattning : Reinforced concrete is one of the most widely used building materials and if it is properly designed and produced, it is an extremely durable material with a service life up to 100 years. However, under certain environmental conditions the service life of reinforced concrete structures is more limited. LÄS MER

  2. 2. Chloride initiated reinforcement corrosion in marine concrete

    Detta är en avhandling från Division of Building Materials, LTH, Lund University

    Författare :Paul Sandberg; Lunds universitet.; Lund University.; [1998]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cover thickness; w c ratio; chloride penetration; service life prediction; corrosion cells; chloride thresholds; field exposure tests; marine concrete; pozzolans; reinforcement corrosion; chloride binding; Building construction; Byggnadsteknik;

    Sammanfattning : Factors affecting the total chloride threshold for initiation of pitting corrosion in reinforced concrete were investigated by means of field and laboratory exposure tests. Factors affecting the chloride penetration into concrete were also investigated by means of field tests. The thesis consists of a summary (86 p.) and 11 papers attached. LÄS MER

  3. 3. Chloride Homeostasis in Central Neurons

    Detta är en avhandling från Umeå : Umeå University

    Författare :Tushar Yelhekar; Umeå universitet.; [2016]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chloride concentration; current-voltage relation; interpolation; voltage ramp; reversal potential; [Cl–]i recovery; KCC2; extracellular matrix; GABAA receptor; chloride leak conductance; neurosteroid; Physiology; fysiologi;

    Sammanfattning : The overall aim of the present thesis is to clarify the control of intracellular chloride homeostasis in central neurons, because of the critical role of chloride ions (Cl–) for neuronal function. Normal function of the central nervous system (CNS) depends on a delicate balance between neuronal excitation and inhibition. LÄS MER

  5. 5. Chloride Channels and Brown Fat Cells

    Detta är en avhandling från Stockholm : Wenner-Grens institut för experimentell biologi

    Författare :Victor Sabanov; Stockholms universitet.; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chloride channel; BAPTA; EGTA; Ca; NATURAL SCIENCES Biology Organism biology Animal physiology; NATURVETENSKAP Biologi Organismbiologi Zoofysiologi;

    Sammanfattning : Chloride ion channels are macromolecular pores providing for passage of chloride ions (and certain other inorganic and organic anions) through the cell membrane, down their electrochemical gradients. Chloride channels are differentially expressed in various cells, to best suit specific cellular activities. LÄS MER
