this study investigates natural frequency analysis of an fg composite rectangular plate partially contacting with a bounded fluid. the material properties are assumed to be varying continuously through the thickness direction according to a simple power law distribution in terms of volume fraction of material constituents. wet dynamic transverse displacements of the plate are approximated by a ...

Performance of Cordyceps militaris mutant obtained by high-energy ion beam irradiation regarding anti-cancer agent cordycepin production in submerged culture was investigated. It was established that the mutant renders a higher production performance in surface liquid culture, needs to observe its performance in submerged culture. Two kinds of media were used for submerged culture comprising a ...

scour around hydraulic structures is an inevitable phenomenon . recognition of this phenomenon and dealing with it is an issue considering which will ensure the project success . local scour at piers has been reported as the most important factor in the destruction of the bridges . the use of submerged and non-submerged piles is one of the scour control methods . submerged piles have been rarel...

The relationships between long-term (;115-year) phosphorus and sediment accumulation and submerged macrophyte biomass were determined both within a submerged macrophyte bed and among beds in Lake Memphremagog, Quebec, Canada. Strong relationships between present submerged macrophyte biomass and littoral-zone sediment and phosphorus accumulation rates both within and among macrophyte beds yielde...

Foster, McDaniel, Woodruff, and Stokes (1945) recently described the formation of conidia by molds of the genus Penicillium during submerged growth in liquid culture media. Controlling or associated factors for this phenomenon were described as the presence of a rather high calcium-ion concentration and, in general, the development of considerably less mycelium before spore formation than is fo...

We present a new derivation of the momentum exchange algorithm first introduced by Ladd [12], to compute the flow force and torque on a submerged body. The starting point of our derivation is to consider the time derivative of the total momentum of a virtual fluid system that replaces the submerged body in the real problem. The new derivation gives, in turn, some correction terms to the origina...
