The heat flux on the divertor plate of a fusion reactor is probably one of the most limiting constraints on its lifetime. The current heat flux profile on the outer divertor plate of a device like the International Thermonuclear Experimental Reactor (ITER) is highly peaked with narrow profile. The peak heat flux can be as high as 30-40 MW/m 2 with full width at half maximum (FWHM) of the order ...

The Reissner-Mindlin plate models thin plates. The condition numbers of finite element approximations of these plate models increase very rapidly as the thickness of the plate goes to 0. A Balancing Domain Decomposition by Constraints (BDDC) Deluxe method is developed for these plate problems discretized by Falk-Tu finite elements. In this new algorithm, subdomain Schur complements restricted t...

The influence of the curvature of a conductor plate used as a reference in free space method is considered both by experiments and by theoretical computations. First, it is observed that the reflection coefficient varies as much as 3 dB by changing the orientation or the surface of the plate. Next, a numerical simulation is performed using physical optics approximation method. It is confirmed t...

Although less researched and put into practice in the building environment, pure plate structures are to be observed frequently in biological structures. The 3-plate principle which is common in the morphology and growth pattern of natural systems is also found to be of a structurally optimum content when considered from a plate point of view. This is for instance the case of the sea urchin’s p...

this paper has focused on vibration and buckling of thin rectangular plates when at least two opposite sides are simply supported condition and subjected to axial and biaxial initially stresses. analysis is based on exact solution method, without further usage of any approximate method. first analytic techniques are used to discuss the free vibrations of plate. then, natural frequencies and cri...

Although the multiplication of bacteriophages (phages) has a substantial impact on the biosphere, comparatively little is known about how the external environment affects phage production. Here we report that sub-lethal concentrations of certain antibiotics can substantially stimulate the host bacterial cell’s production of some virulent phage. For example, a low dosage of cefotaxime, a cephalo...

We present an overview of the relation between mantle dynamics and plate tectonics, adopting the perspective that the plates are the surface manifestation, i.e., the top thermal boundary layer, of mantle convection. We review how simple convection pertains to plate formation, regarding the aspect ratio of convection cells; the forces that drive convection; and how internal heating and temperatu...

Springer, Victor G. Pacific Plate Biogeography, with Special Reference to Shorefishes. Smithsonian Contributions to Zoology, number 367, 182 pages, 65 figures, 5 tables, 1982.—It is the thesis of this study that the Pacific lithospheric plate (Pacific Plate) forms a major subunit of the Indo-Pacific biogeographic region. This thesis is defended on two primary grounds: the sharp decrease in numb...

In our laboratory, culture of sputum was extremely useful in diagnosing the etiology of pneumococcal pneumonia. Of 31 consecutive patients with bacteremic pneumococcal pneumonia, 29 (94%) had Streptococcus pneumoniae cultured from sputum. Recovery of pneumococci in culture was enhanced by anaerobic incubation as well as by a plate bile test and an optochin disk on a primary blood agar plate.
