Well-dispersed Rh(OH)3 nanoparticles were deposited in the interlayer galleries of a Dion-Jacobson type layered perovskite (ACa2Nb3O10: A=H or K). X-ray photoelectron spectra and zeta potential measurements suggest covalent bonding (Rh-O-Nb) between the nanoparticles and the niobate sheets. After calcination of Rh(OH)3/KCa2Nb3O10 at 350 degrees C in air, interlayer Rh(OH)3 nanoparticles were tr...

Recombinant human (rh) interleukin-3 (IL-3) stimulated the proliferation and differentiation of erythroid, granulocyte, macrophage, eosinophil (Eo), and mixed colonies as well as megakaryocytes from human bone marrow cells. rh IL-3 was a weaker stimulus than rh granulocyte-macrophage colony-stimulating factor (GM-CSF) for day 14 myeloid cell colonies. At day 7 of incubation, rh IL-3 stimulated ...

functional response of trichogramma brassicae bez. to different densities of eggs of two host species anagasta kuehniella zell. and plodia interpunctella hub. was studied under laboratory conditions (24±1°c, 65±10% rh and 16: 8 l:d photoperiodism). one day old eggs of either host were offered to individual females of t.brassicae in densities 2, 4, 8, 16, 32, 64 and 128 respectively in 21, 15, 1...

Rhombohedral dense forms of carbon, rh-C2 (or hexagonal h-C6), and boron nitride, rh-BN h-B3N3), are derived from rhombohedral 3R graphite based on original crystal chemistry scheme backed with full cell geometry optimization to minimal energy ground state computations within the quantum density functional theory. Considering throughout settings featuring extended lattices, calculation set elas...

Rh-based heterogeneous catalysts generally have limited selectivity relative to their homogeneous counterparts in hydroformylation reactions despite of the convenience of catalyst separation in heterogeneous catalysis. Here, we develop CoO-supported Rh single-atom catalysts (Rh/CoO) with remarkable activity and selectivity towards propene hydroformylation. By increasing Rh mass loading, isolate...

objective(s):helicobacter pylori infection occurs worldwide, but the prevalence of this infection varies greatly among different countries and population groups. the aim of this study was to determine the seroprevalence of anti-helicobacter pylori and anti-cytotoxin-associated gene a (caga) antibodies in asymptomatic healthy population in the center of iran and to investigate the relation with ...

Aims: The aim of the present study is to examine microRNA (miRNA or miR)-605-3p expression in melanoma at tissue and cellular levels, and to understand its biological roles. Methods: A total of 45 melanoma patients (27 males and 18 females) were enrolled in this research. To measure the expression of miR-605-3p, quantitative real-time polymerase chain reaction was employed. Melanoma A375 cells ...

We present and analyse a family of fully discrete spline Galerkin methods for the solution of boundary integral equations with logarithmic kernels. Following the analysis of Galerkin methods of a previous paper, we show the existence of asymptotic expansions of the error. In this work we deal with the numerical solution of the integral equation Z 1 0 log jx( ) x(s)j2g(s)ds = u0(s); 8s; where u0...

Rh(ttp)(C(7)H(7)) rearranged to give Rh(ttp)(CH(2)Ph) quantitatively at 120 °C in 12 d (ttp = 5,10,15,20-tetratolylporphyrinato dianion). This process is 10(10) faster than for the organic analogue. Mechanistic investigation suggests that a Rh(II)(ttp)-catalyzed pathway is operating.
