Carboranes have attracted increasing interest in the scientific community due to their remarkable structures and strong electron-withdrawing abilities. In this article, four platinum complexes [(C^N^N)PtC[triple bond, length as m-dash]CPh](1), [(C^N^N)PtC[triple bond, length as m-dash]C-TPA](2), [(C^N^N)PtC[triple bond, length as m-dash]C-TAB](3), [(C^N^N)PtC[triple bond, length as m-dash]C-CB]...

Triple helix formation with pyrimidine deoxyoligonucleotides for the sequence-specific recognition of DNA duplex targets suffers from a decrease in affinity as the pH of the medium increases to that of physiological fluids. A solution to this problem has been identified and entails the substitution of N6-methyl-8-oxo-2'-deoxyadenosine (M) for the 5-methyl-deoxycytosine base residues. The triple...

We study ηc and J/ψ hadroproduction induced by multiple scattering off fixed centres in the target. We determine the minimum number of hard scatterings required and show that additional soft scatterings may be factorized, at the level of the production amplitude for the ηc and of the cross section for the J/ψ. The J/ψ provides an interesting example of soft rescattering effects occurring inside...

Coastal California has evolved through a series of plate tectonic interactions that significantly affected the geologic, thermal, and hydrocarbon maturation histories of the area. Numerical solutions for steady-state heat transfer are used to estimate temperature suppression resulting from plate subduction along coastal California, and to model thermal refraction within the Pismo basin. Numeric...

The classification, up to isomorphism, of all self-embedding monomial power permutations of Hamming Steiner triple systems of order n = 2m − 1 for small m, m ≤ 22, is given. As far as we know, for m ∈ {5, 7, 11, 13, 17, 19}, all given self-embeddings in closed surfaces are new. Moreover, they are cyclic for all m and nonorientable at least for all m ≤ 19. For any non prime m, the nonexistence o...

The new conjugated organometallic polymer (-spacer-C[triple bond]C-Pt(PBu3)2-C[triple bond]C-)n (3; spacer = para-bis(diphenyl(tetramethyl)quinone diimine) and the cyclic mononuclear model complex, spacer'-C[triple bond]C-Pt(PEt3)2-C[triple bond]C x CuCl (4; spacer' = ortho-diphenyl-2,3,5,6-tetramethyl-1,4-benzoquinone diimine) were synthesized from the 1:1 condensation of the corresponding die...

According to a prevailing theory, (2S,4R)-4-hydroxyproline (Hyp) residues stabilize the collagen triple helix via a stereoelectronic effect that preorganizes appropriate backbone torsion angles for triple-helix formation. This theory is consistent with the marked stability that results from replacing the hydroxyl group with the more electron-withdrawing fluoro group, as in (2S,4R)-4-fluoroproli...

today, a correct understanding and skills necessary to reform affairs as well as a culture based on knowledge and continuous learning in the organizations are important elements in the management of sports organizations. so the present study aimed to investigate the relationship between triple management skills (conceptual, humanistic, technical) and organizational learning in managers of physi...

Let V(G) and E(G) denote the vertex and edge sets of a graph G respectively. Let Z, = (0, 1, . . . , n l}. Let K,, be the complete graph on n vertices. An m-cycle is a simple graph with m vertices, say uo, . . . , u,__~ in which the only edges are uou,_i and the edges joining ui to Ui+l (for 0 s i 6 m 2). We represent this cycle by (uo, . . . , u,_J or (uo, u,_~, u,_~, . . . , ul) or any cyclic...
