BACKGROUND Accurate assessment of volume status is essential in diagnosis and guidance of decongestive therapy in patients with acute heart failure. We sought to compare peripheral venous pressure (PVP) with central venous pressure (CVP), as well as other invasive hemodynamic measurements, in patients hospitalized with an acute heart failure syndrome. METHODS AND RESULTS PVP-HF (Peripheral Ve...

In this study sodium alginate (NaAlg)/poly(vinyl pyrrolidone) (PVP) blend membranes were prepared and crosslinked with CaCl2 (0.1 Molarity (M)) for the separation of aqueous/dimethylformamide (DMF) mixtures. Membranes were characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and their performance was examined by varying experimental parameters such...

J. Inst. Brew. 111(1), 20–25, 2005 Proanthocyanidins have been characterized and levels compared in an ale and a lager using normal-phase liquid chromatography– mass spectroscopy (LC/MS) after a pre-concentration step employing Sephadex LH-20 chromatography. Twenty proanthocyanidins were identified including both non-galloylated and galloylated forms of the monomers, dimers and trimers. Oligome...

Abstract The electrochemical actions of ondansetron (OND) were investigated on the modified electrode with Polyvinyl Pyrollidone (PVP) and multi-walled carbon nanotube (MWCNTs). oxidation peak current was enhanced to be doubled when compared bare as a result synergistic effect nanomaterial cation-exchange polymer electron transfer rate. Following optimization experimental conditions, Square Wav...

Contaminated waterways, particularly effluent from the dye industry, are one of major issues today. Among various methods adsorption is most straightforward, effective, and successful to treat such effluents. For this purpose Copper oxide nanoparticles (CuO) embedded within Polyvinyl alcohol (PVA) pyrrolidone (PVP) mixed polymer (CuO/PVA-PVP) were synthesized using precipitation different analy...

The functional properties of polyvinyl pyrrolidone/polyvinyl alcohol (PVP/PVA) blend incorporated with non-stoichiometric tin sulphide (SnS) have been explored for optoelectronic devices. PVP/PVA Sn/S ratios (1:0.8–1:1.2) 1.0 wt.% SnS were prepared by casting method. effect the ratio on structure, optical and photoluminescent (PL) composite was examined Fourier transform infrared, UV-visible-NI...

The analysis of the problem of conjunction of information and communication technologies (ICT) with packaging industry and food production was made. The perspective of combining the latest advances of nanotechnology, including nanophotonics, and ICT for creating modern smart packaging was shown. There were investigated luminescent films with zinc oxide nanoparticles, which change luminescence i...

Title of Document: SYNTHESIS, CHARACTERIZATION, AND KINETIC STUDIES OF IONIZING RADIATION-INDUCED INTRAAND INTER-CROSSLINKED POLY(VINYL PYRROLIDONE) NANOHYDROGELS Jung-Chul An, Doctor of Philosophy, 2007 Directed By: Professor Mohamad Al-Sheikhly, Department of Materials Science and Engineering A polymer nanohydrogel can be defined as a three-dimensional polymer network composed of hydrophilic ...

A micro segmented-flow approach was utilized for the isolation soil bacteria that can degrade synthetic polymers as polyethylene glycols (PEG) and polyacrylamide (PAM). We had been able to obtain many strains; among them, five Achromobacter spanius strains from samples of specific sampling sites were connected with ancient human impacts. In addition characterization community responses isolatin...
