This is a continuing attempt in a series of papers KM 93, Mur 93, Mur 94] to show how computer-represented knowledge can be arranged as elements of an eeectively represented semantic domain in the sense of GS 90]. We present a direct deductive description of the domain, which was deened semantically in KM 93], via the Scott's notion of information system. Also, the internal structure of the con...

For surfaces of revolution B in R, we investigate the limit distribution of minimum energy point masses on B that interact according to the logarithmic potential log(1/r), where r is the Euclidean distance between points. We show that such limit distributions are supported only on the “out-most” portion of the surface (e.g., for a torus, only on that portion of the surface with positive curvatu...

We prove that a completely symmetric and trace-free rank-4 tensor is, up to sign, a Bel-Robinson type tensor, i.e., the superenergy tensor of a tensor with the same algebraic symmetries as the Weyl tensor, if and only if it satisfies a certain quadratic identity. This may be seen as the first Rainich theory result for rank-4 tensors.

We consider the problem of the nature and possible types of spacetime singularities that can form during the evolution of FRW universes in general relativity. We show that by using, in addition to the Hubble expansion rate and the scale factor, the Bel-Robinson energy of these universes we can consistently distinguish between the possible different types of singularities and arrive at a complet...

Screening by a double-disk synergy test identified a Pseudomonas aeruginosa isolate that produced a clavulanic acid-inhibited expanded-spectrum beta-lactamase (ESBL). Cloning and sequencing identified a novel ESBL, BEL-1, weakly related to other Ambler class A ESBLs. beta-Lactamase BEL-1 hydrolyzed significantly most expanded-spectrum cephalosporins and aztreonam, and its activity was inhibited...

Using estrone and pregnenolone as starting materials, some steroidal copper complexes were synthesized by the condensation of steroidal ketones with thiosemicarbazide or diazanyl pyridine and then complexation of steroidal thiosemicarbazones or steroidal diazanyl pyridines with Cu (II). The complexes were characterized by IR, NMR, and HRMS. The synthesized compounds were screened for their cyto...

N, Nbis(2-chloroethyl)aminobenzoyl picolinoyl hydrazide(BABPH), a benzoic acid nitrogen mustard based new compound and its metal complexes(Cu2+ and Zn2+) have been synthesized and characterized by elemental analysis, IR, 1HNMR, EPR, electronic spectrum, and molar conductivity measurements. In the present study, both BABPH and its complexes exhibited in vitro excellent inhibition of L1210, K562 ...

Acute postprandial gastric dilatation and associated clostridial enteritis necroticans is a well recognised but unusual clinical condition. Non-pathological overeating, gastric distension, and clostridial enteritis, termed pig-bel, has been reported in Papua, New Guinea. A similar condition (Darmbrand) was reported from Germany after the second world war, but it is not a condition seen in our s...

A series of novel N-anilino-5-methyl-2-(3-(5-(alkylaminomethyl)furan-2-yl-methylthio)propyl)-[1,2,4]triazolo-[1,5-a]pyrimidine-7-amine derivatives were synthesized and evaluated for their in vitro cytotoxicity against two cancer cell lines, Bel-7402 and HT-1080. Compounds 9, 14, 19 and 23 possessed marked cytotoxicity, especially 23 (with IC(50) values of 15.0 microM and 7.8 microM against Bel-...
