Currents evoked in neurons of the vertebrate CNS by the glutamate agonist N-methyl-D-aspartate (NMDA) exhibit a marked voltage dependence in the presence of extracellular Mg. At the single-channel level, the addition of external Mg alters single-channel openings from long-lived events to many very short events grouped into bursts of openings. These bursts apparently result from short interrupti...

PhD “The role of intumescent flame retardants on the fire behavior of poly(vinyl acetate) and poly(ethylene-co-vinyl acetate): a mechanistic and kinetic study.”

The statistical rate theory (SRT) fundamental kinetic equation for the Langmuir model of adsorption reveals some features which are difficult to understand. These are the infinitely high adsorption rate for zero coverage limit, infinitely high desorption rate at full saturation of the surface and dependence of the desorption rate on the adsorbate pressure. These features do not allow for a corr...

In the present research, the effect of standoff distance on corrosion properties of the joint of three aluminum–steel explosive layers has been studied. For this purpose, the samples were welded with various standoff distance under constant explosive load. Optical Microscopy and Scanning Electron Microscopy were used to measure the quality of the joint and type of interface. Furthermore, point ...

A new activated carbon was produced from pulp and paper mill sludge as a low cost precursor via chemical activation by zinc chloride. The activated carbon was successfully used for the adsorption of phenol and two of its derivatives, i.e. 2-chlorophenol and 4-nitrophenol from aqueous solutions. The characterization of the prepared activated carbon demonstrated high textural properties for the s...

the binding behavior of a competitive inhibitor, n-phenylbenzhydroxamic acid (bha) against horseradish peroxidase (hrp) was studied in order to understand and predict the interaction mechanism of hydrogen donors with the enzyme. the dissociation constants of the complexes of hrp-bha, hrp-donor and hrp-bha-azide were estimated at specified conditions by difference spectroscopy. the binding site ...

In this paper, we prove effective estimates for the number of exceptional values and the totally ramified value number for the Gauss map of pseudo-algebraic minimal surfaces in Euclidean four-space and give a kind of unicity theorem.

This paperdescribes awayof organizing information about an object-orientedprogram’s execution. The context is our system for visualizing that execution. The critical constraints are completeness, compactness, and efficient retrieval. We describe our design and how it meets these constraints.
