[1] To assess the current status of climate models in simulating clouds, basic cloud climatologies from ten atmospheric general circulation models are compared with satellite measurements from the International Satellite Cloud Climatology Project (ISCCP) and the Clouds and Earth’s Radiant Energy System (CERES) program. An ISCCP simulator is employed in all(More)
Alkyl-N-phenyl carbamates (2-8) (see Figure 1), alkyl-N-phenyl thiocarbamates (9-15), 2,2'-biphenyl-2-ol-2'-N-substituted carbamates (16-23), and 2, 2'-biphenyl-2-N-octadecylcarbamate-2'-N-substituted carbamates (24-31) are prepared and evaluated for their inhibition effects on porcine pancreatic cholesterol esterase and Pseudomona species lipase. All(More)
Factor XIII catalysis proceeds via formation of thioester acyl enzyme intermediate involving an active site cysteine residue at position 314. The contribution of other residues to catalysis has not been established. Earlier studies of the pH dependence of factor XIII activity suggested the existence of a putative active site histidine. We used chemical(More)
Radiationless energy transfer from tyrosine to Tb(III) in Escherichia coli glutamine synthetase and its two mutants (W57L and W158S) has been utilized to assess the tyrosine residue(s) responsible for the observed tyrosine emission and to investigate its spatial relationships to the two metal binding sites of GS. The interference from tryptophan(More)
Large eddy simulation of a three-dimensional spatially developing transitional free methane non-premixed flame is performed. The solver of the governing equations is based upon a projection method. The Smagorinsky model is utilized for the turbulent subgrid scale terms. A global reaction mechanism is applied for the simulation of methane/air combustion.(More)
Abstract: This study relies on integrated inventory theory which merges with the supply chain concept and aims at the steel bar material of precast factory’s two-echelon supply chain system. In order to consider the variable demand rate, unfixed supply time, unfixed supply frequency and unfixed supply quantity, this study builds a strategic model that(More)
The cDNA encoding human cytosolic phospholipase A2 (cPLA2) has been subcloned into a prokaryotic pET16b expression vector which also encodes an amino-terminal deca-histidine affinity tag to facilitate purification of the recombinant enzyme. Soluble, active fusion protein, designated His-cPLA2, has been obtained reproducibly from this expression system using(More)
Stopped-flow fluorescence experiments have been carried out at 23 degrees C to study the hydrolysis of Leu-Gly-NHNH-Dns [Dns = 5-(dimethylamino)naphthalene-1-sulfonyl] and Leu-Gly-NH(CH2)2NH-Dns by porcine kidney cytosol leucine aminopeptidase (LAP). Experiments have been performed with LAP species containing Mg(II), Mn(II), Ni(II), Cu(II), Zn(II), and no(More)
The origin of the fluorescence changes observed in stopped-flow experiments of the hydrolysis of three 5-(dimethylamino)naphthalene-1-sulfonyl-(dansyl) peptide substrates by porcine kidney cytosol leucine aminopeptidase has been investigated. The substrates used all have the potential to accept energy from aromatic residues of the enzyme via resonance(More)
