1. 11. Factors influencing splanchnic microcirculation in animal models of endotoxaemia

   Författare :Andreas Andersson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Microcirculation;

   Sammanfattning : Even though severe sepsis and septic shock therapy has improved in recent years, mortality remains high (22-50%). Disturbances in splanchnic organ homeostasis and increases in gut permeability have long been presumed to contribute to systemic inflammation and multiple organ dysfunction syndrome in critical illness and septic shock.

3. 12. Mechanisms of Biopolymer Solvation: Development of a two-component ionic liquid solvent system

   Författare :Susanne Bylin; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; ionic liquids; solvation; mechanism; xylan; lignin; cellulose; wood components;

   Sammanfattning : Ionic liquids are of potential interest in the processing of lignocellulosic biomass, and/or its components, for the purpose of producing renewable and value-added biomaterials. An understanding of how solvation can be achieved and the way in which the feedstock biopolymers are affected, however, needs to be gained prior to a viable implementation. LÄS MER

4. 13. Particle Engineering by Spherical Crystallization:Mechanisms and Influence of Process Conditions

   Författare :Jyothi Thati; Åke Rasmuson; Stephane Veesler; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spherical agglomeration; Benzoic acid; Solubility; Phase diagram; Physico- mechanical properties size distribution; particle morphology and crushing strength; elastic recovery; compressibility ; Chemical engineering; Kemiteknik;

   Sammanfattning : Spherical agglomerates of benzoic acid crystals have been successfully prepared by drowning-out crystallization in three solvent partial miscible mixtures. Benzoic acid is dissolved in ethanol, bridging liquid is added and this mixture is fed to the agitated crystallizer containing water as the anti-solvent. LÄS MER

5. 14. On Phase Behaviours in Lipid/Polymer/Solvent/Water Systems and their Application for Formation of Lipid/Polymer Composite Particles

   Författare :Anna Imberg; Per Hansson; Krister Thuresson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Biodegradable; CLSM; Composite Particles; Controlled Release; Cubic Phases; Drug Delivery; Flory-Huggins Theory; FT-PGSE-NMR; IPMS; Liquid Phase; Lipid Domains; Liquid Handler; Microspheres; Microstructure; Phase Behaviour; Phase Separation; Polymer Matrix; SAXS; Segregation; Sponge Phase; Swelling; Fysikalisk kemi; Physical chemistry; Fysikalisk kemi; fysikalisk och oorganisk farmaceutisk kemi; Physical and Inorganic Pharmaceutical Chemistry;

   Sammanfattning : A new kind of lipid/polymer composite particle, consisting of a biodegradable polymer matrix with well-defined lipid domains, has been created. The lipid used is the water-swelling lipid monoolein (MO), which forms a reversed bicontinuous cubic diamond structure in aqueous solutions. LÄS MER

7. 15. Thermophysical Properties of Aqueous Solutions Used as Secondary Working Fluids

   Författare :Åke Melinder; Björn Palm; Antero Aittomäki; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Secondary working fluids; secondary refrigerants; indirect systems; aqueous solutions; ice slurry; thermophysical properties; freezing point; density; viscosity; specific heat; thermal conductivity; Mechanical and thermal engineering; Mekanisk och termisk energiteknik;

   Sammanfattning : Secondary working fluids (secondary refrigerants, heat transfer fluids, antifreezes, brines) have long been used in various indirect re-frigeration and heat pump systems. Aqueous solutions (water solu-tions) have long been used as single phase (liquid only) secondary working fluids for cooling in supermarkets, ice rinks, heat recovery systems, heat pumps and other applications.
