M-MgAlO mixed oxide catalysts were prepared by controlled thermal decomposition of layered double hydroxides (LDH) precursors and tested in the hydrodeoxygenation benzyl alcohol. LDH with Mg/Al = 3 10 at. % M respect to cations (M Mn, Fe, Co, Ni, Cu Zn) obtained coprecipitation. A second series copper-containing copper content from 5 20 was also prepared. The solids characterized X-ray diffract...

in this study, the densities, excess molar volumes and partial molar volumes of four binary systems containing n,n-dimethyl acetamide (dmac) with 1-alkanols (1-butanol up to 1-heptanol) are measured at 298.15 k. the results showed both constructive and expansive excess volumetric behavior for studying binary mixtures. deviation values of heavy alcohol have more positive and less negative excess...

Pea aphid, Acyrthosiphon pisum , is a serious pest of many different leguminous plants, and it mainly relies on its odorant receptors (Ors) to discriminate among host species. However, less known about the role that Ors play in plant location. In this study, we identified novel conserved receptor clade by phylogenetic analysis, conducted functional analysis ApisOr23 A. . The results showed homo...

We develop a linear response theory of solvation of ionic and dipolar solutes in anisotropic, axially symmetric polar solvents. The theory is applied to solvation in polar nematic liquid crystals. The formal theory constructs the solvation response function from projections of the solvent dipolar susceptibility on rotational invariants. These projections are obtained from Monte Carlo simulation...

Focal mechanical stimulation of single neonatal mouse cardiac myocytes in culture induced intercellular Ca(2+) waves that propagated with mean velocities of approximately 14 micrometer/s, reaching approximately 80% of the cells in the field. Deletion of connexin43 (Cx43), the main cardiac gap junction channel protein, did not prevent communication of mechanically induced Ca(2+) waves, although ...

Propagation in cardiac muscle is faster in the longitudinal than in the transverse axis of the cells. Yet, as a result of the larger upstroke velocity of action potentials propagating transversely, it has been suggested that longitudinal propagation is more vulnerable to block. To study the relation between conduction velocity and maximal upstroke velocity (Vmax), as well as the time course of ...

We here describe intercellular calcium waves as a novel form of cellular communication among thymic epithelial cells. We first characterized the mechanical induction of intercellular calcium waves in different thymic epithelial cell preparations: cortical 1-4C18 and medullary 3-10 thymic epithelial cell lines and primary cultures of thymic "nurse" cells. All thymic epithelial preparations respo...
