    The effect of temperature on the water electrolysis reactions on nickel and nickel-based codeposits (1988)

    Notes: Abstract Usually, an increase in the temperature of operation leads to a reduction in the voltage of operation of commercial water electrolyzers. The present work analyzes this effect in connection with the overpotential of the hydrogen and oxygen evolution reactions on electrodeposited nickel and some nickel-based codeposits which under normal operational conditions have shown good electrocatalytic characteristics. Results on pure nickel are also presented for comparison. A pressure chamber, adequate for electrochemical studies at high temperatures and pressures is described.

    Notes: Abstract Mother rats nursing large litters are hyperphagic, aggressive towards conspecifics, and show less freezing behaviour than non-maternal animals. These naturally occurring adaptations resemble those elicited by benzodiazepine treatment in virgin rats, indicating a common neurochemical change in the brains of mother rats and benzodiazepine-treated virgins. In line with this hypothesis, it was found that three functional benzodiazepine antagonists (FG 7142, pentylenetetrazol, caffeine) decreased food intake, lowered aggression and strengthened freezing in lactating mother rats. These psychopharmacological observations support the idea that GABA neurotransmission is enhanced during motherhood in the rat.
