M. S. R. Nair, I. Leong and M. S. B. Nayar. Ichthyotoxins from the oyster toadfish Opsanus tau Nike Free 4.0 V3 Womens (Linnaeus). Toxicon20, 933–935, 1982.—The oyster toadfish, Opsanus tau, secretes an ichthyotoxic mucous active against silversides (Menidia menidia). The structures of the toxins isolated, aliphatic ketones, are different from any of the known toxins from marine vertebrates.
The Monte Carlo program TRIM SP was used to determine sputtering yields and angular and energy distributions of sputtered particles. The influence of the inelastic energy loss model on the sputtering yield is shown to be of great importance. Agreement of the calculated results with experimental data is reasonably good, even in very detailed analysis.
The authors consider the nth-order nonlinear neutral delay differential equation [y(t)+P(t)y(g(t))](n)+ δQ(t)f(y(h(t)))=0, where n⩾1, Q(t)⩾0 and δ=±1. They give sufficient conditions for solutions to either oscillate or converge to zero.
Tokyo-based Mitsubishi Corporation says that its prototype electrolyzer High-pressure Hydrogen Energy Generator (HHEG) has achieved the world's first production of high-pressure Nike Free Running Canada
hydrogen gas without a compressor. The HHEG PEM electrolyzer holds a cell stack in a high-pressure vessel, which stores the highly compressed hydrogen generated by electrolysis.
