Feasibility Study of Shaped Electrode The objective of this project was a feasibility study of a novel, large-area plasma reactor for thin film production, based on a shaped electrode technique (“lens”) to compensate the standing wave non-uniformity. Cylindrical Test Reactor In the first phase a cylindrical reactor was designed and constructed to show the “proof of principle” of a novel electro...

ABSTRACT: The mechanical parameters of constitutive equations for soil and rock can be determined by laboratory experiments in which a cylindrical specimen is commonly tested under uniaxial and triaxial compressive conditions. The distribution of stress in the specimen during the tests must be kept uniform and homogeneous. In this paper, numerical simulations are carried out to determine the di...

Innovative fiber-coupled add-ons for light sheet-based fluorescence microscopy (LSFM) with commercial inverted microscopes were described previously [1]. The light sheet is generated either by an achromatic cylindrical lens or by a spherical mirror with astigmatic distortion. Presently the “lens system” is further validated and applied to various samples including 3D multicellular spheroids and...

The percentage depth dose in the build-up region and the surface dose for the 6-MV photon beam from a Varian Clinac 23EX medical linear accelerator was investigated for square field sizes of 5 × 5, 10 × 10, 15 × 15 and 20 × 20 cm(2)using the EGS4nrc Monte Carlo (MC) simulation package. The depth dose was found to change rapidly in the build-up region, and the percentage surface dose increased p...

Plasma immersion ion implantation (PIII) into gearywindmill structures is simulated by the particle-in-cell (PIC) method in cylindrical co-ordinates. In cylindrical co-ordinates, the gearywindmill geometry becomes a periodic regular structure. An equal number of particles are placed inside the cell with the same angular and radial distance. The ion density represented by each particle is obtain...

BACKGROUND Recent cadaver studies show stability against axial rotation with a cylindrical cage is marginally superior to a rectangular cage. The purpose of this biomechanical study in cadaver spine was to evaluate the stability of a new rectangular titanium cage design, which has teeth similar to the threads of cylindrical cages to engage the endplates. METHODS Ten motion segments (five L2-3...

We describe how the Kitaev honeycomb model with a finite number of sites on a torus may be easily generalised to cylindrical and rectangular topologies using a recently developed fermionisation technique. We then look for criteria which determine if zero-energy modes exist for these cases in the absence of an external magnetic field. For the cylindrical case, we determine the combination of spi...
