EXTENT is an EXpert system for TENsor product formula Translation. In this paper we present a programming environment for automatic generation of parallel/vector programs from tensor product formulas. A tensor (Kronecker) product based programming methodology is used for designing high performance programs on various architectures. In this programming(More)
Some manganese(II) complexes derived from different sulphadrugs and heterocyclic ketones have been prepared. These complexes have been characterized on the basis of elemental analyses, molecular weight determinations, conductivity measurements, infrared, ESR and magnetic measurements. The spectral data suggest that the ligands act in a monobasic, bidentate(More)
The organosilicon derivatives of 2-[1-(2-furayl)ethyledene]sulphathiazole with organosilicon chlorides have been synthesised and characterized on the basis of analytical, conductance, and spectroscopic techniques. Probable trigonal bipyramidal and octahedral structures for the resulting derivatives have been proposed on the basis of electronic, IR, (1)H,(More)
Some antifertility inhibitors of 18 to 24-membered tetraazamacrocyclic complexes of iron(II) and manganese(II) have been synthesised by the template condensation using 1,3-phenylenediamine with malonic acid, succinic acid, glutaric acid and adipic acid. The reaction proceed smoothly to completion. The complexes were characterized by elemental analyses,(More)
Synthetic, spectroscopic and antimicrobial aspects of some fertility inhibitor heterobimetallic complexes have been carried out. These heterobimetallic chelates [M(C(5)H(5)N(3))(2)M(2)'(R)(4)]Cl(2) (M = Pd or Pt and M' = Si, Sn, Ti and Zr) have been successfully synthesinzed via the reaction of M(C(5)H(7)N(3))(2)Cl(2) with group four or fourteen dichlorides(More)
1. Five White Leghorn (WLH) strains, namely G, H, I, J and C, differing in selection history, were screened for randomly amplified polymorphic DNA (RAPD) polymorphism using 50 random decamer primers. 2. Only 12 primers detected polymorphism between the strains. Out of 96 bands scored using these primers, only 21 (21.9%) were found to be polymorphic. 3.(More)
