The piezoelectric ~PZ! effect is demonstrated for the elongated three-dimensional ~In,Ga!As islands grown on a GaAs ~100! substrate. The photoluminescence ~PL! spectrum is studied as a function of excitation intensity. With increasing excitation intensity, a blue shift and a linewidth reduction of the PL peak from the ~In,Ga!As islands are observed. The observed phenomena are attributed to the ...

In this paper, we focus on one type of labeling is called range labeling, have introduced for certain graphs as Pz, Cz, Sy,z(Double star), sun graph and some trees.

The kinetics of reduction of [Ru(III)(edta)pz]⁻ (edta⁴⁻ = ethylenediaminetetraacetate; pz = pyrazine) by thioamino acids (RSH = cysteine, glutathione) resulting in the formation of a red [Ru(II)(edta)pz]²⁻ species (λ(max) = 462 nm) has been studied spectrophotometrically using both conventional mixing and stopped-flow techniques. The time course of the reaction was followed as a function of [RS...

We consider the shape of the magnetic Compton profile (MCP), Jmag(pz), in La1.2Sr1.8Mn2O7 for momentum transfer pz along the [110] direction and the associated reciprocal form factor B(r) defined by taking the one-dimensional Fourier transform of Jmag(pz). B(r) is shown to contain a prominent dip at rz1 Å, where the minimum value Bmin of B(r) can be related to the occupancies of the eg orbitals...

This paper considers an integrated formulation in selecting the best normal mean in the case of unequal and unknown variances. The formulation separates the parameter space into two disjoint parts, the preference zone (PZ) and the indifference zone (IZ). In the PZ we insist on selecting the best for a correct selection (CS1) but in the IZ we define any selected subset to be correct (CS2) if it ...

The tridentate ligand 2,6-bis(3,5-diphenylpyrazol-1-ylmethyl)pyridine, abbreviated as 2,6-[(3,5-ph₂pz-CH₂)₂-py], a new pyridine-pyrazole derivative, was prepared from 2,6-bis(bromomethyl)pyridine and 3,5-diphenylpyrazole. The ligand was characterized by means of elemental analyses, ATR-IR, ¹H- and ¹³C-NMR spectroscopy and single crystal X-ray crystallography. Using this ligand, a new mononuclea...

This paper discusses in detail our approaches for producing the submitted summaries to TRECVID, including the two baseline methods. The cluster method performed well in terms of coverage, and adequately in terms of user satisfaction, but did take longer to review. We conducted additional evaluations using the same TRECVID assessment interface to judge 2 additional methods for summary generation...

Permeable reactive barriers (PRBs), a new cost effective technology for the remediation of contaminated groundwater, have rarely been considered for PAH contamination. We evaluated three candidate matrices (activated carbon (AC), pouzzolana coated (PzF) or not (Pz) with heavy fuel oil) for phenanthrene (PHE) sorption capacity and the biodegradation of adsorbed PHE. Adsorption-desorption batch e...

As long ago as 1930, Kosaka and Lim proposed a humoral agent capable of inhibiting gastric acid secretion after a meal. They coined the term enterogastrone. Using crude preparations of cholecystokinin-pancreozymin (CCK PZ) in dogs they were able to inhibit the acid secretion normally stimulated by a meat meal or histamine. They went on to experiment with duodenal extracts, prepared after the in...
