Here, we report the synthesis, characterization, and catalytic evaluation of Ni-Cu-Mg ferrite using tragacanth gum as biotemplate and Metals nitrate as the metal source by the sol-gel method without using any organic chemicals. The sample was characterized by powder X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FT-IR), Vibrating Sample Magnetometer (VSM), and Scanning El...

The mononuclear title complex, [Ni(C50H46N2O4)], crystallizes in the triclinic space group P-1, with two mol-ecules in the asymmetric unit (Z' = 2). Each Ni(II) atom has a slightly distorted square-planar geometry [ω = 3.91 (5)° and 2.04 (7)°] defined by the two phenolate O and two imine N atoms of the tetra-dentate Schiff base ligand. The dihedral angles between the central phenolate ring and ...

a r t i c l e i n f o Zn–Ni, Zn–Co and Zn–Ni–Co coatings were electrodeposited on mild steel from an acidic chloride bath containing p-aminobenzenesulphonic acid (SA) and gelatin. These additives changed the phase content in the coatings, most likely as a result of their adsorption at the surface of the cathode. The effect of gelatin was more pronounced than that of SA. The Faradaic efficiency ...

We investigated, using a direct, intravital microscopic technique, whether nitric oxide (NO) from neuronal nitric oxide synthase (nNOS) plays a role in the cerebral capillary flow response to acute hypoxia. Erythrocyte flow in subsurface capillaries of the frontoparietal cortex of adult Sprague-Dawley rats was visualized using epifluorescence videomicroscopy after fluorescent labeling of red bl...

BACKGROUND Pancreatic incidentaloma (PI) is an increasingly common diagnosis that has received little attention. We characterized these tumors and compared them with symptomatic pancreatic tumors (nonincidentaloma [NI]). STUDY DESIGN A retrospective database of 475 consecutive pancreatectomies that were performed from January 1995 to June 2007 at our institution was analyzed. Data for PI and ...

The capability of a region to generate advanced technology, information and ultimately knowledge is regarded as the single most important force driving economic growth. This paper provides benchmarks for the innovation performance of manufacturing businesses in the three NUTS 2 regions of Ireland (Border Midlands & West, South & East, Northern Ireland) in 1999, just prior to the start of the cu...

In the title compound, [Ni(C(11)H(13)N(2)O(4))(2)]·C(3)H(7)NO, the Ni(II) ion is octa-hedrally coordinated in an N(2)O(4) environment by two identical Schiff base ligands. The Ni-O bond lengths range from 2.004 (2) to 2.106 (2) Å, while the Ni-N bond lengths are 2.038 (2) and 2.0465 (19) Å. The cis bond angles range from 78.64 (8) to 97.30 (8)°, with the former being due to the small bite of th...

Several factors are implicated in the increased vulnerability of multiple trauma victims to infection, especially in intensive care-units (ICU). This cohort study was designed to report the incidence, the topography, the etiology and to identify the risk factors for infection in trauma patients admitted in an ICU. From January 2000 to December 2001, 416 trauma patients were admitted to the ICU ...

In the Mekong River delta and its associated coastal zone trace elements concentrations (Cd, Cu, Ni and Pb) were measured in the dissolved phase (DP) during dry (March 1997) and wet (October 1997) seasons. As, Co, Cr, Ni, Pb, and Al were also measured in suspended matter (SM) and total and organic carbon, trace elements (Cd, Cr, Cu, Hg, Mn, Ni, Pb, Zn) and macro elements in superficial sediment...

BACKGROUND Shed membrane microparticles circulate in the peripheral blood of nonischemic (NI) patients and patients with myocardial infarction (MI). We investigated whether or not these microparticles would affect endothelium-dependent responses. METHODS AND RESULTS Rat aortic rings with endothelium were exposed for 24 hours to circulating microparticles isolated from 7 patients with NI syndr...
