  1. 1. Shear and Torsion Interaction in Prestressed Hollow Core Slabs

    Author : Helén Broo; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shear-torsion capacity; hollow core unit; shear and torsion interaction; non-linear finite element analyses; hollow core slab; precast prestressed concrete; hollow core floor;

    Abstract : There are many applications in which hollow core units are subjected to combined torsion and shear, for example in floors supported on three edges and in floors with openings. The traditional calculation method for combined shear and torsion in hollow-core units adds stresses from various sources without taking into account deformations and compatibility within the unit or restraint at the boundaries.

  2. 2. Hollow Cathode Deposition of Thin Films

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Lars-Erik Gustavsson; Uppsala universitet.; [2006]
    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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Daniel Söderström; Uppsala universitet.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; hollow cathode; hybrid plasma; vibrational temperature; atmospheric pressure; fluid modelling; radio frequency; pulsed power; Teknisk fysik; TECHNOLOGY Engineering physics; TEKNIKVETENSKAP 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

  4. 4. Plasma Enhanced Chemical- and Physical- Vapor Depositions Using Hollow Cathodes

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Kaspars Siliņš; Uppsala universitet.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hollow cathode; TiN; AlN; amorphous carbon; hybrid PVD PE-CVD; ionized magnetron;

    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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Saadia Bashir Hassan; Uppsala universitet.; [2004]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacology; CHS 828; in vitro; in vivo; hollow fiber; models; NF-kB; Farmakologi; MEDICINE Physiology and pharmacology Pharmacological research; MEDICIN Fysiologi och farmakologi 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.
