This work aims to study of the stability of two generalizations of the functional equation f (pr,qs)+ f (ps,qr) = f (p,q) f (r,s) , namely (i) f (pr,qs)+g(ps,qr) = h(p,q)h(r,s) , and (ii) f (pr,qs)+ g(ps,qr) = h(p,q)k(r,s) for all p,q,r,s ∈ G , where G is a commutative semigroup. Thus this work is a continuation of our earlier works [15] and [16], and the functional equations studied here arise...

The integrity of a graph G, I(G), is defined by I(G) = minS⊆V (G){|S| + m(G − S)} where m(G− S) is the maximum order of the components of G− S. In general the integrity of r-regular graph is not known [?]. We answer the following question for special regular graphs. For any given two integers p and r such that pr 2 is an integer, is there a r-regular graph, say G ∗, on p vertices having size q ...

The title compound, {[Pr(C(2)H(6)OS)(8)](2)[Mo(6)Ag(6)S(24)]}(n), contains polymeric Mo(6)S(24)Ag(6) (2-) anions and [Pr(Me(2)SO)(8)](3+) cations, forming a one-dimensional polymeric Mo/S/Ag cluster. The anion assumes the conformation of a zigzag chain. The trivalent cations are arrayed amongst the anionic chains and are well separated from each other. Each Mo and Ag atom is coordinated by four...

The performance of a new heuristic search algorithm is analyzed. The algorithm uses a formal representation (semantic representation) that contains enough information to compute the heuristic evaluation function h (n). as defined in the context of A *. without requiring a human expert to provide it. The heuristic is computed by �olving less constrained subproblems (auxiliary problems) of the gi...

The boundary between well structured and ill structured ~roblems is vague, fluid and not susceptible to formalization. Any problem solving process w'iii appear ill structured i f the problem solver is a serial machine that has access to a ~w:-y iarge long-term memory o f potentially relevant information, and]or access to a very large exterlm! memory that provides information about the actual re...

The human progesterone receptor (PR) contains multiple Ser-Pro phosphorylation sites that are potential substrates for cyclin-dependent kinases, suggesting that PR activity might be regulated during the cell cycle. Using T47D breast cancer cells stably transfected with an mouse mammary tumor virus (MMTV) chloramphenicol acetyltransferase reporter (Cat0) synchronized in different phases of the c...

The ligation of a N-heterocyclic carbene (NHC) to group 11 metal salts (Cu, Ag) was explored as an alternative to PR(3) ligands for the formation of copper- and silver-chalcogenolate cluster complexes. AgOAc and CuCl salts ligate with the NHC 1,3-di-isopropylbenzimidazole-2-ylidene ((i)Pr(2)-bimy) forming [Ag(OAc)((i)Pr(2)-bimy)] 1, [Ag(OAc)((i)Pr(2)-bimy)(2)] 2, [CuCl((i)Pr(2)-bimy)](2)3 and [...

Samsun NN tobacco cells were transformed with chimeric genes for pathogenesis-related (PR) proteins derived from genomic (PR-1a, GRP) or cDNA (PR-S) clones under the transcriptional control of the cauliflower mosaic virus 35S promoter. Regenerated plants were assayed by RNA and protein gel blotting, and plants showing high specific expression of the inserted genes were selected for self-pollina...
