Interactions of azide ion with bovine heart cytochrome c oxidase (CcO) at five redox levels (IV) to (0), obtained by zero to four electron reduction of fully oxidized enzyme CcO(IV), were monitored by infrared and visible/Soret spectra. Partially reduced CcO gave three azide asymmetric stretch band at 2040, 2016, and 2004 cm-1 for CcO(III)N3 and two at 2040 and 2016 cm-1 for CcO(II)N3 and CcO(I...

We report a photoelectron spectroscopy and computational study of hydrated N3 anion clusters, N3(H2O)n (n ) 0-16), in the gas phase. Photoelectron spectra of the solvated azide anions were observed to consist of a single peak, similar to that of the bare N3, but the spectral width was observed to broaden as a function of cluster size due to solvent relaxation upon electron detachment. The adiab...

Azide complexes of Ga(III) have attracted con­ siderable attention in recent years owing to their importance as precursors for the formation of GaN [1-4] . Gallium nitride is a rather stable III-V semi­ conductor with interesting optical properties which can be utilized for optoelectronic applications in­ cluding blue light-emitting diodes and lasers [5 7]. The thermal decomposition of Ga(N3)3 ...

n3 polyunsaturated fatty acids have been reported to have anti-carcinogenic effects on mammalian carcinomas. n3 fatty acids occur in high concentrations in marine oils, especially shark liver oils. Several reports have indicated an extremely low incidence of cancer in sharks, although other reports indicate carcinogenesis in some shark species. It has been hypothesised that n3 fatty acids and o...

Given graphs H and F , a subgraph G ⊆ H is an F -saturated subgraph of H if F * G, but F ⊆ G + e for all e ∈ E(H) \ E(G). The saturation number of F in H, denoted sat(H,F ), is the minimum number of edges in an F -saturated subgraph of H. In this paper we study saturation numbers of tripartite graphs in tripartite graphs. For ` ≥ 1 and n1, n2, and n3 sufficiently large, we determine sat(Kn1,n2,...

Protein kinase C(PKC ) is critical for TCR-initiated signaling in mature T cells, but initial reports found no requirement for PKC in thymocyte development. Thymocytes and peripheral T cells utilize many of the same signaling components and, given the significant role of PKC in peripheral T cells, it was surprising that it was not involved at all in TCR signaling in thymocytes. We decided to re...

In this paper we consider the all-pairs shortest path (APSP) problem, which computes shortest paths between all pairs of vertices of a directed graph with non-negative real numbers as edge costs. We present an algorithm that computes shortest distances between all pairs of vertices, since shortest paths can be computed as by-products in our algorithm. It is well known that the time complexity o...

A clinical study was undertaken to evaluate the associations between the tissue levels of omega-3 (N3), also known as the Omega-3 Index (N3 Index), on various clinical and quality of life outcomes in healthy young adults after heavy eccentric exercise.. To ensure an adequate number of participants with an elevated N3 index would be available for comparison to those with a lower N3 Index, a subg...

We show that necessary and sufficient conditions for the existence of a semi-evenly partite star factorization of the symmetric complete tripartite digraph K~I,n2,n3 are (i) k is even, k 2 4 and (ii) nl = n2 = n3 == 0 (mod k(k -1)/3) for k == 0 (mod 6) and nl = n2 = n3 == 0 (mod k(k 1)) for k == 2,4 (mod 6).
