In this work, we experimentally investigated the cavitation effects on hydrodynamic behavior of a circular cylinder at different cavitating flows. We analyzed dynamics behind using high-speed camera and also measured associated forces load cell. studied around various types regimes such as cloud cavitation, partial inception. addition, three Reynolds numbers: 1 × 105, 1.25 105 1.5 105. The resu...

The association between embryos of the spotted salamander (Ambystoma maculatum) and green algae ("Oophila amblystomatis" Lamber ex Printz) has been considered an ectosymbiotic mutualism. We show here, however, that this symbiosis is more intimate than previously reported. A combination of imaging and algal 18S rDNA amplification reveals algal invasion of embryonic salamander tissues and cells d...

The Poh et al. (2012) paper describes the first biophysically based computational model of human jejunal smooth muscle cell (hJSMC) electrophysiology. ionic currents are described by either a traditional Hodgkin-Huxley (HH) formalism or deterministic multi-state Markov (MM) formalism. We create modularized CellML implementation model, which is able to reproduce clamping behaviours individual an...

When green hydra were grown in continuous darkness the mean cell size of their symbiotic algae was smaller than when grown in light and numbers of algae per digestive cell were reduced. The former was due to a reduction in size at which the algae divided, and the latter to a loss of synchrony of algal mitosis with that of digestive cells after transfer to darkness. Eventually, algal mitosis reg...

Natural convection heat transfer was investigated experimentally in a concentric-cylinders annulus. To enhance the rate of heat transfer, pin fins were installed on the surface of the inner cylinder. Two fin arrangements were employed, namely, staggered and in-line arrangements. The length of the fins varied from 2 to 8 cm and the Rayleigh number Ra changed in the range from 5 x 105  to 5 x 106...

The seasonal variations in algal compositions quantitatively and qualitatively have been studied for two stations Alwnd River, represented before after passing Khanqeen city through eight months starting December 2000. A total of 123 phytoplankton taxa were identified, dominated by diatoms (63 species) followed greens (34 species), blue-greens (15 11 species other groups. cell number ranged bet...

Lack of high-density algal photobioreactors (PBR) has been a limitation in exploiting the biotechnological potential of algae. Recent developments of highly efficient light-emitting diodes (LED using gallium aluminum arsenide chips) have made the development of a small LED-based PBR possible. We have calculated theoretical values of gas mass transfer requirements and light-intensity requirement...
