The title compound, [Zn(C(6)H(4)N(5))(2)(H(2)O)(4)]·4H(2)O, was synthesized by the hydro-thermal reaction of Zn(CH(3)COO)(2)·2H(2)O with 3-(2H-tetra-zol-5-yl)pyridine. The Zn(II) ion is located on an inversion center and is coordinated by two pyridine N atoms from two 5-(3-pyrid-yl)tetra-zolide ligands and four coordinated water mol-ecules in a slightly distorted octa-hedral geometry. The dihed...

Tetra-amelia is a rare malformation that may be associated with other anomalies and is usually inherited in an autosomal recessive pattern. We describe a fetus, born to a nonconsanguineous couple, with tetra-amelia, bilateral cleft lip and palate and bilateral lung agenesis, without other anomalies. Karyotype was normal (46,XX) and premature centromere separation was excluded. No mutation was i...

The structure of the title compound, LuP(5)O(14), comprises puckered eight-membered PO(4) rings linked by the lutetium cations in a complex way, forming a three-dimensional framework. Each eight-membered phosphate ring shares a bridging tetra-hedron with each of four adjacent tetra-hedra, to form layers of PO(4) tetra-hedra. These layers are c/2 in thickness and parallel to the ab plane. Each L...

The structure of the title compound, [Al2(OH)2(C6H12N2O)6]I4·4C6H12N2O (systematic name: di-μ2-hydroxido-bis-{tris-[1,3-di-methyl-tetra-hydro-pyrimidin-2(1H)-one-κO]aluminium} tetra-iodide 1,3-di-methyl-tetra-hydro-pyrimidin-2(1H)-one tetra-solvate), is composed of two Al(C6H12N2O)3 moieties linked into a centrosymmetric dinuclear unit by a pair of bridging hydroxide ions. The aluminium cations...

Manufacturing process and performance analysis of a non-frost refrigeration system are presented in this paper. Main objectives research were to suggest better refrigerant as well propose technique for further reduction the power consumption system. Performance was evaluated Tetra-fluoro-ethane Isobutene refrigerant. From experiment, it is found that, coefficient with than Tetra-fluoro-ethane. ...

A series of novel tetra-meso-thien-2-yl porphyrins were synthesised, and the effect variation in thienyl group on photophysical properties studied. Ground excited state UV–vis absorption, steady-state time-resolved emission, resonance Raman spectroscopy, cyclic voltammetry, used to establish extent electronic communication between central Zn(II) porphyrin ring various meso-substituent groups. T...

Prasugrel {systematic name: 5-[(2-cyclo-propyl-carbon-yl)(2-fluoro-phen-yl)meth-yl]-4,5,6,7-tetra-hydro-thieno[3,2-c]pyridin-2-yl acetate}, C(20)H(20)FNO(3)S, is a new third-generation thienopyridine which was recently approved for clinical use as a more potent blocker of the platelet P2Y(12) receptor than clopidogrel, which was previously used for this purpose. The mol-ecule features a tetra-h...

In disaster management scenarios with seriously damaged, not existing, or saturated communication infrastructures satellite communications can be an ideal means to provide connectivity with unaffected remote terrestrial trunked radio (TETRA) core networks. However, the propagation delay imposed by the satellite link affects the signalling protocols. This paper discusses the suitability of using...
