We exhibit explicit, combinatorially defined graphs satisfying the kth extension axiom: Given any set of k distinct vertices and any partition of it into two pieces, there exists another vertex adjacent to all of the vertices in the first piece and to none in the second. Quisani:1 I’ve been reading about zero-one laws, and many of the results involve extension axioms. In the simple case of grap...

background clinical observations have shown that patients infected with chronic hepatitis b virus (hbv) genotype c versus genotype b had a higher load of the virus, more serious illness, and poorer responses to antiviral therapy and prognosis. however, the disparity between the two has not been clarified. objectives to explore possible relationship between hbv genotypes b and c and peripheral b...

a competitive spectrophotometric method has been used for the study of complexation between cu2+, zn2+ and cd2+ (m) and 18-crown-6(18c6, b) in methanol using 4-(2-thiazolylazo) resorcinol (tar, hl) as the colorimetric complexant. absorption spectra of the species in the m-tar-18 c6 system at a various concentrations of 18c6 showed no formation of ternary complex, mlb, and the stoichiometry of t...

biodegradable polymeric nanoparticles (nps) have been intensively studied as a possible way to enhance anti-tumor efficacy while reducing side effects. icd-85, derived from the venom of two separate species of venomous animals, has been shown to exhibit anti-cancer activity. in this report polymer based sodium alginate nanoparticles of icd-85 was used to enhance its therapeutic effects and redu...

introduction: 64cu-pyruvaldehyde-bis(n4-methylthiosemicarbazone) (64cu-ptsm)‍ is one of the most important copper radiopharmaceuticals used in clinical experiments. methods: in this work, copper-64 (t1/2=12.33 h) production has been presented followed by the synthesis of the complexing agent, ptsm, and its structure was confirmed by common spectroscopic methods followed by radiolabeling with 64...

In not much more than a decade the practice of implementing programs for testing satisfiability of propositional formulas has progressed from being practically a curiosity to an active and competitive endeavor. Impressive performance improvements have made SAT solvers useful in some industrial applications, most notably in formal verification of hardware and software systems as the engine for b...

cu(ii) complex with l-histidine (his) ligand, immobilized within al-mcm-41, designated as cu(his)2/al-mcm-41 was prepared and characterized by powder x-ray diffraction (xrd), nitrogen adsorption desorption, ftir, uv-vis and chemical analysis techniques. the surface area and pore volume were found to decrease after immobilization of cu(ii) complex on al-mcm-41. it was found that cu(his)2/al-mcm-...

conclusions the synergistic effect was found on the healing of infected wounds caused by s. aureus by using an mbp-1 and silver nanoparticles combination in a mouse model. results the mic and mbc of mbp-1 were found to be 0.6 and 0.7 mg/ml, respectively. mic and mbc of silver nanoparticles were determined to be 6.25 and 12.5 mg/l, respectively. mic and mbc of the silver nanoparticles and mbp-1 ...
