  2. 6. Kidney Hyaluronan : Regulatory Aspects During Different States of Body Hydration, Nephrogenesis & Diabetes

    Author : Louise Rügheimer; Peter Hansell; Cecilia Johnsson; Örjan Källskog; Mats Rundgren; Uppsala universitet; []
    Keywords : Physiology; hyaluronan; kidney; dehydration; hydration; diabetes; nephrogenesis; renomedullary interstitial cells; CD44; hyaluronan synthase; hyaluronidase; vasopressin; nitric oxide; prostaglandins; glucocorticoids; angiotensin II; diuresis; lymph vessel; podoplanin; Fysiologi;

    Abstract : The kidney regulates the excretion of water and electrolytes, which maintains homeostasis and enables control of arterial blood pressure. Hyaluronan, a large negatively charged interstitial glucosaminoglycan, is heterogeneously distributed within the kidney, primarily found in the medulla. READ MORE

  4. 7. Acceptor-doped barium zirconate: Oxidation, hydration and space-charge formation

    Author : Anders Lindman; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; BaZrO3; space charge; point defects; oxidation; GW; hydration; density functional theory; grain boundaries; interatomic potential; perovskites;

    Abstract : The current production and use of fossil fuels is not sustainable and new technologies are needed to become more independent of these fuels.The hydrogen economy, with the fuel cell as an efficient converter of chemical to electrical energy, is a desirable alternative.For this to become a reality, new materials with tailored properties are required.

  5. 8. Interaction of water with supplementary cementitious materials: Hydration mechanism, microstructure and moisture transport

    Author : Liming Huang; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydration; moisture transport; Supplementary cementitious materials; electrical conductivity; formation factor; durability; microstructure;

    Abstract : Supplementary cementitious materials (SCMs) offer a sustainable solution to reduce carbon emissions from the production of cement and concrete. This dissertation explores the impact of SCMs and the related additives on the hydration process of cementitious materials, which can affect their microstructure and transport properties. READ MORE

  6. 9. Water and alkali salts in the hydrating and hardened green cement-based materials: Hydration process, moisture content and transport

    Author : Liming Huang; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Formation factor; Electrical conductivity; Moisture transport; Pore structure; Sustainable cement-based materials; Hydration; Alkali salts; Supplementary cementitious materials;

    Abstract : Reducing CO2 emissions in the production of cementitious binder is the most effective way to decrease the environmental impact of the construction industry, so a large amount of supplementary cementitious materials (SCMs) has been used in the green concrete. Both the SCMs and alkali salts in binders influence the hydration process and the structure in hardened cement-based materials. READ MORE

  7. 10. Hydration, pore structure, and related moisture properties of fly ash blended cement-based materials : Experimental methods and laboratory measurements

    Author : Oskar Linderoth; Avdelningen för Byggnadsmaterial; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cement; Murbruk; Betong; Hydratation; Porstruktur; Sorption; Fukttransport; Mineraliska tillsatsmaterial; Flygaska; Cement; Mortar; Concrete; Hydration; Pore structure; Water vapour sorption; Moisture transport; Supplementary cementitious materials; Fly ash;

    Abstract : Cement-based materials, such as mortar and concrete, are the most employed construction materials in the world. Cement is an important component; it reacts with water to form a glue, called cement paste, which causes the material to harden. Today, cement production accounts for a significant portion of the world’s annual carbon dioxide emissions. READ MORE
