A property of graphs is any class of graphs closed under isomorphism. A property of graphs is induced-hereditary and additive if it is closed under taking induced subgraphs and disjoint unions of graphs, respectively. Let P1,P2, . . . ,Pn be properties of graphs. A graph G is (P1,P2, . . . ,Pn)-partitionable (G has property P1◦P2◦ · · · ◦Pn) if the vertex set V (G) of G can be partitioned into ...
The title compound, C(23)H(17)N(3)O, has been previously described in a monoclinic P2(1)/c polymorph with Z = 4 [Asiri, Al-Youbi, Faidallah, Ng & Tiekink (2011). Acta Cryst. E67, o2449]. In the new monoclinic P2(1)/n form, with Z = 8, there are two independent mol-ecules, A and B, in the asymmetric unit. In both mol-ecules, the cyclo-hexa-1,3-diene ring has a screw-boat conformation, whereas it...
کمپلکس cis-[ptcl2(dppb)] از واکنش کمپلکس cis, trans-[ptcl2(sme2)2] و لیگاند dppb و کمپلکس cis-[ptcl2(dpppe)] از واکنش dpppe و k2ptcl4 با راندمان بالا به دست آمد. کمپلکسهایcis-[ptbr2(p2)] (p2 = dppa, dppb, dpppe) نیز از واکنش k2ptbr4و لیگاندهای فوق تشکیل شدند. همچنین کمپلکس های cis-[ptx2(p2)] (p2 = dppf, dppm, dppe, dppp, dppb, dpppe ; x = br, i) از واکنش کمپلکس هایcis-[ptcl2(p2)] و kx (x...
HPV infections are common and the presence of the same high-risk type in cervical specimens can be due to reinfection or persistence. Persistent infection is the most important predictor for development of cervical carcinoma. The aim of this study was to validate PCR-RFLP with two sets of primers: MY09/MY11 that amplify a fragment of L1 and P1/P2 that amplify a fragment of E1 ORF. PCR product o...
Working group one focused on problems associated with the use of distributed applications. Initially several possible topics of discussion were considered including the growth of the world wide web (WWW), problems of lag across networks, the high resource requirements of particular tasks in distributed collaboration and the impact on current theories and techniques for design and modelling. The...
