  2. 11. Glucose degradation products in peritoneal dialysis fluids

    Author : Martin Erixon; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Medicine human and vertebrates ; 4-dideoxyglucosone-3-ene; 3; cytotoxicity; storage; temperature; Glucose degradation products biocompatibility; sterlization; Medicin människa och djur ; Analytical chemistry; Analytisk kemi;

    Abstract : Patients suffering from renal failure must remove extracellular water and waste products from their body in order to survive. One way of doing this is by treatment with peritoneal dialysis (PD). READ MORE

  4. 12. Theory of Ion Temperature Gradient Driven Instabilities: Threshold and Transport

    Author : Shi Chong Guo; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The object of this thesis is the theory of the ion temperature gradient driven (ITGD) mode, including instabilities, thresholds and associated anomalous transport. The linear threshold has been investigated both analytically and numerically in various parameter domains. READ MORE

  5. 13. Transport Coefficients during Drying of Solids containing Multicomponent Mixtures

    Author : Rafael Gamero; Joaquín Martínez; Evangelos Tsotsas; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; capillary; conduction; convection; diffusion; evaporation; heat transfer; hydraulic conductivity; liquid film; liquid transport; mass transfer; Maxwell-Stefan diffusion coefficients; molar fluxes; phase equilibrium; temperature gradient; ternary mixture; thermodynamic factors; Chemical engineering; Kemiteknik;

    Abstract : This study investigated the transport coefficients involved in mass and heat transfer during the drying of a porous solid partially saturated with multicomponent mixtures.  It included the coefficients governing liquid transport through the solid, the matrix of multicomponent diffusion coefficients in the liquid phase, and the effective thermal conductivity.

  6. 14. Variation in age and size at maturation in two benthic crustaceans in the Gulf of Bothnia

    Author : Kjell Leonardsson; J. Ekman; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Age at maturation; alternative prey; Bergmanris rule; cannibalism; growth; life-history theory; mortality; Mvoxocephalus quadricornis; poikilotherm; Pontoporeia affinis; population dynamics; risk- taking behaviour; Saduria entomon; size at maturation; temperature;

    Abstract : The thesis deals with variation in age and size at maturation in Saduria entomon and Pontoporeia affinis along a depth gradient in the Gulf of Bothnia, Sweden. I have analysed at what sizes and ages animals should mature in relation to growth and mortality conditions. READ MORE

  7. 15. Thermal plasticity and limitations in tropical trees

    Author : Maria Wittemann; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; acclimation; African tropical forest; chlorophyll fluorescence; climate change; drought; hydraulic; montane; photosynthesis; respiration; successional strategies; temperature; tropical trees; warming;

    Abstract : Tropical forests are the most carbon dense and biodiverse terrestrial biome on earth. In a time of global warming and biodiversity crisis, their preservation must be of high priority. At the same time, they likely operate close to their thermal limits because of a historically and seasonally stable environment. READ MORE
