  2. 11. Drowning-out crystallisation of benzoic acid : Influence of processing conditions and solvent composition on crystal size and shape

    Author : Xiomara Holmbäck; KTH; []
    Keywords : solvent effect; drowning-out; crystallization; benzoic acid; solubility; crystal habit; crystal growth; interfacial energy; growth mechanism;

    Abstract : The aim of the present investigation is to increase theunderstanding of the role played by the solvent in inhibitingor enhancing crystal growth. Drowning-out crystallizationexperiments has been performed by the controlled addition ofwater or ethanol water mixtures to a saturated solution ofbenzoic acid in ethanol-water mixtures. READ MORE

  4. 12. Change agents and use of visual management tools in care process redesign : Implications on working conditions for operative managers and healthcare professionals

    Author : Anna Williamsson; Lotta Dellve; Anette Karltun; Andrea Eriksson; Kjellström Sofia; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Technology and Health; Teknik och hälsa;

    Abstract : Swedish healthcare has been subject to change efforts to increase efficiency in care processes. In the 2000-2010’s lean production has influenced healthcare with change approaches such as visual management tools to increase patient flows and efficiency. READ MORE

  5. 13. Corrosion of current cullector materials in the molten carbonate fuel cell

    Author : Baohua Zhu; KTH; []
    Keywords : molten carbonate fuel cell MCHC ; corrosion; current collecotr; contact corrosion reistance;

    Abstract : The corrosion of current collector materials in MoltenCarbonate Fuel Cells (MCFC) is investigated. The essential aimsof this investigation were to study the corrosion behaviour ofdifferent materials, in varying cathode and anode MCFCenvironments, and to study the contact corrosion resistancesbetween the MCFC current collector and electrodes.

  6. 14. Geoid Model of Tanzania from Sparse and Varying Gravity Data Density by the KTH method

    Author : Prosper Ulotu; Lars Sjöberg; Hossein Nahavandchi; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geoid; sparse gravity data; gravity database; GGM validation by gravity; corrector surface; hybrid geoid; KTH-LSMS with AC; Mt. Kilimanjaro; Tanzania.; Earth sciences; Geovetenskap;

    Abstract : Developed countries are striving to achieve a cm geoid model. Most developing countries/regions think that the situation in their areas does not allow even a few decimetre geoid model. GNSS, which provides us with position, is one of the greatest achievements of the present time. READ MORE

  7. 15. Material Properties of Bulk Hydrophobic Concrete in a Nordic Environment

    Author : Patrick Rogers; Johan Silfwerbrand; Tang Luping; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; alkyl alkoxysilane; capillary suction; chloride ingress; concrete; hydrophobic agents; triacylglycerides; Betongbyggnad; Concrete Structures;

    Abstract : Concrete in its unaltered form allows the mass transfer of fluids into and out of its microstructure. These fluids can contain detrimental solutes which change the chemistry of the cement paste and/or the corrosion properties of the reinforcement bars, most noticeably hydrogen carbonates (HCO3-), oxygen (O2) and chloride ions (Cl-).
