Ni catalysts supported on Nano porous catalysts were prepared by the impregnation method and tested for vapor phase hydrogenation of benzene. The textural and physico-chemical properties of Ni catalysts were characterized by the X-ray diffraction, Fourier-transform infrared spectroscopy, scanning electron microscope and N2 adsorption-desorption analysis. The catalytic evaluation reve...

The target article gathers compelling behavioral evidence that motion parallax provides depth information in a variety of animal species. A more general evaluation of kinetic depth cues subserving depth perception would call attention to recent studies in monkeys, demonstrating the interrelation of kinetic and stereoscopic depth cues both on a behavioral and physiological level. Furthermore, it...

background: the purpose of this study was to investigate the ratio of electromyography (em g) activities of the vastus medialis obliqus (vmo) and vastus lateralis (vl) within seven angles of knee joint range of motion using isometric contraction in open kinetic chain (ok c) and closed kinetic chain (ckc). methods: the dominant knees of 44 healthy female subjects (mean age: 24.84 with range: 20-...

The photocycle of the acid-purple form of bacteriorhodopsin (BR) was studied by multiwavelength absorption kinetic measurements. The data were evaluated using a new method based on the differences in the kinetics of the absorption changes at different wavelengths [Tokaji, Zs. (1995) FEBS Lett. 357, 156-160]. The evaluation indicates that, in contrast to the previous suggestion, the photocycle o...

The chemoenzymatic dynamic kinetic resolution of β-amino esters is established after detailed evaluation metal-based heterogeneous catalysts for racemization and enzyme resolution.
