We describe a method for preparing highly enriched cultures of Drosophila myoblasts from a heterogeneous cell population derived from gastrulating embryos. Enriched cultures are prepared by plating this heterogeneous population of cells in medium from which much of the free calcium is chelated by ethylene glycol-bis(beta-aminoethyl ether)N,N,N',N'-tetraacetate (EGTA). Adhesion of myoblasts to t...

Introduction: In vitro dosimetric verification prior to patient treatment plays a key role in accurate and precision radiotherapy treatment delivery. Since the human body is a heterogeneous medium, the aim of this study was to design a heterogeneous pelvic phantom for radiotherapy quality assurance. Material and Methods: A pelvic phantom was ...

A simple and efficient one-pot three-component synthesis of the biologically important spirooxindole-4H-pyrans was carried out by the reaction of isatin, activated methylene reagents, and 4- hydroxycoumarin in aqueous medium. SBA-Pr-NH2 was found to be an efficient heterogeneous nanoporous solid basic catalyst (pore size of 6 nm) which can be easily handled and removed from the reaction mi...

The saponification of an aromatic ester with an aqueous sodium hydroxide was studied within a heterogeneous reaction medium in order to determine the overall kinetics of the selected system. The extended thermo-kinetic model was developed compared to the previously used simple one. The reaction rate within a heterogeneous liquid-liquid system incorporates a chemical kinetics term as well as mas...

This demonstration shows our versatile heterogeneous sensor networks testbed. This testbed supports high speed embedded WLAN node, medium speed IEEE802.15.4 node, wired computer and so on with powerful supervision platform. The unique features of the testbed are as follows: (1) Supporting heterogeneous sensor networks; (2) Owning powerful testbed nodes; (3) Emulating the interference and noise ...

We present a generalization of the finite volume evolution Galerkin scheme [17, 18] for hyperbolic systems with spatially varying flux functions. Our goal is to develop a genuinely multi-dimensional numerical scheme for wave propagation problems in a heterogeneous media. We illustrate our methodology for acoustic waves in a heterogeneous medium but the results can be generalized to more complex...

In highly heterogeneous media waves do not propagate ballistically. They interact several times with the heterogeneities of the medium and enter the multiple scattering regime. In this regime, classical imaging techniques based on direct or singly scattered waves fail. This is typically the case in fault zones and volcanoes, two highly heterogeneous structures that are of great interest for man...

Multigrid methods are described for solving the pressure equation arising from a finite element discretization of the equations modeling the flow of two immiscible and in-compressible fluids in a heterogeneous porous medium. Comparisons are made between the performance of these methods and a preconditioned conjugate gradient algorithm by solving some two dimensional five spot problems on both h...
