In the complex (bispyridine -2 and 6-dicarboxylate copper II)) at position H number 26 with modifications of ligands such as vinyl, acetylene and isopropyl, changes in the valance / charge ratio for oxygen and carbon atoms in these complexes have been investigated by methods Initial calculations (ab initio) have been performed at two levels of HF, DFT. Finally, their stability is compared with ...

Introduction: The petrogenesis of the low-Ti lunar ultramafic glasses is critical to the understanding of volcanic processes on the Moon. Popular petrologic models developed to explain the formation of these glasses involve high pressure melting of a variety of sources, including primordial, garnet bearing, lunar mantle and depleted lunar magma ocean (LMO) cumu-lates [1,2,3,4]. Following the hi...

Supplier selection negotiation is a sophisticated and challenged job due to the diversity of intellectual backgrounds of the negotiating parties, the many variables involved in supply–demand relationship, the complex interactions and the inadequate negotiation knowledge of project participants. To do the job well, it is necessary to develop an intelligent system for negotiation support in suppl...

Cloud service providers may face the problem of how to price infrastructure services and how this pricing may impact the resource utilization. One aspect of this problem is how Cloud service providers would decide to accept or reject requests for services when the resources for offering these services become scarce. A decision support policy called Customized Bid-Price Policy (CBPP) is proposed...

Iron chrome oxide (FeCr 2O4), is a commercially viable and major ingredient of stainless steel. The Odisha state in India possesses 98% the pre-Cambrian India’s Chromite ore deposits Sukinda valley, Jajpur District. To meet present escalating demand for chromium steel industries, it urged to extract more satiate domestic needs. depletion deposits, rise demand, fewer mines, less conversion from ...

We present evidence for a naturally occurring quasicrystal consisting of micron-sized grains of Al63Cu24Fe13 with icosahedral symmetry embedded in a sample of khatyrkite (nominally, (Cu,Zn)Al2) obtained from the Khatyrka ultramafic zone of the Koryak Mountains in the northern half of the Kamchatka Peninsula.

Human epithelial (A549) cells exposed to hyperoxia die by cellular necrosis. In the current study, we demonstrated the involvement of apoptogenic factors in epithelial cell necrosis in response to hyperoxia, including the formation of the Fas-related death-inducing signaling complex and initiation of mitochondria-dependent apoptotic pathways. We showed increased activation of both Bid and Bax i...

Epithelial ovarian cancer (EOC) cells often show increased activity of the PI3K/Akt pathway. In addition, we have previously shown that EOC ascites induce Akt activation in the tumor necrosis factor-related apoptosis inducing ligand (TRAIL)-sensitive EOC cell line, CaOV3, leading to TRAIL-mediated apoptosis inhibition. In this study, we investigated the role of Akt in intrinsic resistance to TR...
