The severity of Zn deficiency increased with increase in soil exchangeable sodium percentage (ESP) with salt sensitive variety M1-48 scoring 6 at ESP 62 as against only score 3 by salt tolerant variety Pokkali under similar soil conditions. Strikingly, zinc contents were much higher in salt tolerant variety than in salt sensitive one. Zinc application increased zinc concentration in the roots b...

This study aims to determine the optimum parameters for the invert sugar obtaining, using the acid hydrolysis at t oC. The inversion reaction has been applied to 3 samples of sugar solution of different concentration (P1: SU = 70%, P2: SU = 75%, P3: SU = 80%). For obtaining the invert sugar syrup, different inversion temperatures have been used (t1 = 80oC, t2 = 90oC, t3 = 100oC). The inversion ...

A highly selective carbon-carbon bond-forming transformation of carbon dioxide (CO2) to alcohol oxidation level has been disclosed. By employing a copper/bisphosphine catalyst system and hydrosilanes as mild and easy-to-handle reducing agents, various allenes can be reacted with CO2 to regioselectively obtain homoallylic alcohols. Esters and other reducible functionalities on the allenes remain...

A few years ago the writer observed that tungstate filtrates of blood yield considerably higher reducing non-sugar values (nonfermentable reducing substances) when determined with an alkaline ferricyanide reagent than when copper is used as the oxidizing agent. The average reduction values, expressed in equivalents of glucose, were 21 mg. per cent with the modified Shaff er-Hartmann method and ...
