  1. 1. A Collaborative E-learning Approach : Exploring a Peer Assignment Review Process at the University Level in Uganda

    Author : Evelyn Kahiigi Kigozi; Henrik Hansson; Mats Danielson; F. F Tusubira; Mikko Vesisenaho; David Hollow; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; Computer and Systems Sciences; data- och systemvetenskap;

    Abstract : There is an increasing need, driven by the job market, for quality education and that requires expertise which is continuously being developed. The integration of e-learning into the education system is viewed as one way to meet this growing need for high-quality education. READ MORE

  2. 2. Hollow Cathode Deposition of Thin Films

    Author : Lars-Erik Gustavsson; Ladislav Bárdoš; Hana Baránková; Claes Nender; Uppsala universitet; []
    Keywords : Electronics; Hollow cathode; Hybrid plasma; PVD; TiN films; Ferromagnetic substrates; Magnetized plasma; CrN films; Elektronik;

    Abstract : Thin films of metals and compounds have a very wide range of applications today. Many of the deposition methods used for the production of such films utilize plasma to support the growth the film, e.g. by the supply of energy and the enhancement of reactivity. READ MORE

  3. 3. Modelling and Applications of the Hollow Cathode Plasma

    Author : Daniel Söderström; Hana Baránková; Ladislav Bárdos; Zoltán Donkó; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Engineering physics; hollow cathode; hybrid plasma; vibrational temperature; atmospheric pressure; fluid modelling; radio frequency; pulsed power; Teknisk fysik; Engineering physics; Teknisk fysik;

    Abstract : This thesis presents experimental and modelling research on atmospheric pressure hollow cathodes and hollow electrodes. Experiments with the hybrid hollow electrode activated discharge (H-HEAD), which is a combination of a hollow cathode and a microwave plasma source, is presented. READ MORE

    Abstract : Development of coating deposition technologies, in terms of performance and costs, is an ongoing process. A promising class of deposition technologies are based on hollow cathode discharges. READ MORE

  5. 5. Methods for Preclinical Evaluation of Cytotoxic Drugs : With Special Reference to the Cyanoguanidine CHS 828 and Hollow Fiber Method

    Author : Saadia Bashir Hassan; Elin Lindhagen; Rolf Larsson; Mats O Karlsson; Mustapha Hassan; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacology; CHS 828; in vitro; in vivo; hollow fiber; models; NF-kB; Farmakologi; Pharmacological research; Farmakologisk forskning;

    Abstract : The novel cyanoguanidine CHS 828 has shown promising antitumor activity in many in vitro and in vivo studies. The long-term 14 days in vitro hollow fiber cultures, where tumor cells from different tumor cell lines were cultured inside semipermeable fibers, were more resistant to CHS 828 and other cytotoxic drugs than the shorter-term 3 days cultures.
