  2. 21. Air diffusion and solid contaminant behaviour in room ventilation : a CFD based integrated approach

    Author : Gery Einberg; Sture Holmberg; hazim Awbi; KTH; []
    Keywords : Technology; CFD modelling; airflow rate; ventilation efficiency; diffusers; solid contaminants; IAQ; TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : One of the most fundamental human needs is fresh air. It has been estimated that people spend comparatively much time in indoor premises. That creates an elevated need for high-quality ventilation systems in buildings. The ventilation airflow rate is recognised as the main parameter for measuring the indoor air quality. READ MORE

  4. 22. Modelling of Drug Release from Reservoir and Matrix Formulations - Multiple Unit Dosage Forms and Swelling and Dissolving Matrix Systems

    Author : Per Borgquist; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; swelling; XEDS; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Polymer technology; biopolymers; Polymerteknik; Pharmaceutical and related technologies; Läkemedelsteknik och relaterad teknik; simulation; single pellet; single-unit release; SEM; reservoir system; poly ethylene oxide ; film-coated; matrix; mathematical model; diffusion; pellet shape; controlled release; polymer dissolution; modelling; ethyl cellulose; Coating; multiple-unit release;

    Abstract : In this work, mathematical models have been developed describing drug release from film-coated reservoir systems as well as drug release and polymer dissolution from swelling and dissolving polymer tablets. The model derivation of both systems is based on a mechanistic approach. The model describing drug release from reservoir systems, i.e. READ MORE

  5. 23. Structured Metallic Films for Enhanced Light Transmission and Absorption

    Author : Reyhaneh Soltanmoradi; Min Yan; Sanshui Xiao; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Fysik; Physics; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : Photonic devices such as light emitters, detectors, solar cells etc. are playing increasingly important roles in modern society. Yet their structures and designs are still under constant improvement, driven mostly by advances in material science and progress in integration techniques. READ MORE

  6. 24. Conceptual and empirical issues of technological change in the health care sector : Innovation and diffusion of hemodialysis and renal transplantation

    Author : Ann Bonair; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Medical technology; innovation; diffusion; determinants of diffusion; ESRD treatment; ESRD costs; regional variations; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : The present study focuses on one instance of technological change in medical practice; the innovation and diffusion of hemodialysis and renal transplantation (ESRD treatment)- two therapeutic innovations aimed at the treatment of patients suffering from chronic renal failure. The purpose of the thesis is to study the processes by which medical technology is developed imd disseminated. READ MORE
