The task of the visual system is to translate light into neuronal encoded information. This translation of photons into neuronal signals is achieved by photoreceptor neurons (PRs), specialized sensory neurons, located in the eye. Upon perception of light the PRs will send a signal to target neurons, which represent a first station of visual processing. Increasing complexity of visual processing...

The many-body potential for ferromagnetic and paramagnetic rhodium clusters proposed in this work has 11 parameters ~14 for the paramagnetic case! that are fitted on the energy surface of Rh2 through Rh6 clusters calculated from first principles within the generalized gradient approximation ~GGA! of density functional theory. Under this potential the most stable ferromagnetic and paramagnetic c...

the antagonistic effects of rhizobium spp. isolates against rhizoctonia solani (ag-4), the causal agent of bean damping-off were compared with each other in either of the in vitro and in vivo conditions. also their potential to produce such secondary antifungal metabolites as hcn, siderophore and protease were evaluated. the results indicated that, isolate rh3 reduced mycelial growth of r. sola...

Metal clusters supported on carbonaceous substrates are of interest in catalysis, hydrogen storage, and other fields. In this paper, the structures infrared spectra C60Rhn+ (n = 1–6) fullerene-metal complexes studied by a combination mass-selective spectroscopy theoretical calculations. It is found that clustering Rh surface fullerene preferred over wetting. For Rh4+ Rh6+, adsorbed different fr...

Three minor ginsenosides, namely, ginsenoside Rh6 (1), vina-ginsenoside R4 (2) and vina-ginsenoside R13 (3), were isolated from the leaves of hydroponic Panax ginseng. The chemical structures were determined based on spectroscopic methods, including fast atom bombardment mass spectroscopy (FAB-MS), 1D-nuclear magnetic resonance (NMR), 2D-NMR, and, infrared (IR) spectroscopy. The melanogenic inh...
