In this technical report we define an operational net semantics for the stochastic process algebra MPA based on generalized stochastic Petri nets. As a consequence of the definition of such a semantics, we present an interesting modeling technique for concurrent systems which is based on MPA. 1.

The title compound, [Mn(C(8)H(4)N(8))(2)(H(2)O)(5)]·2H(2)O, is the fourth transition metal complex containing the 1,3-di(2H-tetra-zol-5-yl)benzene ligand to be structurally characterized. The Mn^II^ cation has a distorted octahedral coordination geometry. The 1,3-di(tetra-zol-5-yl)benzene ligand is planar. All H atoms bonded to O atoms participate in hydrogen bonds, which link the mol-ecules in...

Reactions of Cp*(2)Zn(2) with sterically demanding bis(iminodi(phenyl)phosphorano)methanes LH (LH = CH(2)(Ph(2)P=NR)(2) (R = Ph L(1)H, SiMe(3)L(2)H, 2,6-i-Pr(2)C(6)H(3) (Dipp) L(3)H) at ambient temperature occurred with elimination of Cp*H and subsequent formation of the homoleptic complex L(1)(2)Zn(2)1 and the heteroleptic complexes LZnZnCp* (L = L(2)2, L(3)3, L(1)4). 3 is the first structural...

A convenient protocol has been developed to fabricate well-defined nanorods of a photochromic molecule N-(3,5-di-tert-butylsalicylidene)-4-aminopyridine (DBSAP) by a laser ablation method. Reversible and fatigue-resistant optical switching and SHG activity were demonstrated. Interestingly, it was observed that DBSAP nanorods exhibit intermediate photochromic properties compared to solution and ...

A recent study using Heckman-type selection models to adjust for non-response in the Zambia 2007 Demographic and Health Survey (DHS) found a large correction in HIV prevalence for males. We aim to validate this finding, replicate the adjustment approach in other DHSs, apply the adjustment approach in an external empirical context, and assess the robustness of the technique to different adjustme...

Twelve 1-phenyl-, 1-thiocarbamoyl- and 1-N-substituted thiocarbamoyl-3-(2-furyl)-5-phenyl/(2-furyl)-2-pyrazoline derivatives were synthesized. The chemical structures of the compounds were proved by IR, (1)H NMR, Mass spectrometric data and microanalyses. The antidepressant activities of the compounds were investigated by Porsolt's behavioural despair (forced swimming) test on albino mice. 1-N-...

The present communication deals with the local anesthetic activity and toxicity of 16 basic alkyl esters of substituted pyrrolidine dicarboxylic acids.t In an accompanying article5 the intestinal, uterine, and depressor activity of these compounds is presented. Twelve of the compounds were 2, 5-di-(3-diethylaminoethyl) esters and 3 were 2, 5-di-(y-diethylaminopropyl) esters. One was 2-(Zdiethyl...
