PublicationArticle Change of platinum resistance by hydrogen(1964) R.J. GalagaliThe change of electrical resistance of platinum in contact with neutral and electrically excited hydrogen, air and argon was studied. Even a trace of hydrogen was sufficient to cool the glowing wire. Influence of ageing and gas pressure showed a marked decrease in the wire resistance. Air and argon showed no appreciable effect on the wire resistance even at higher temperatures.PublicationLetter Irreversible joshi effect: Its thermionic analogue(Kluwer Academic Publishers, 1964) R.J. Galagali[No abstract available]PublicationLetter Simultaneous occurrence of the corona pressure and joshi effect in argon [6](1962) R.J. Galagali[No abstract available]PublicationArticle Simultaneous occurrence of the corona pressure and positive Joshi effect in hydrogen(1964) R.J. Galagali[No abstract available]PublicationArticle Thermionic analogue of joshi effect in maze type counter in argon(1963) R.J. GalagaliExperiments are carried out to explain the occurrence of Joshi Effect in a “free electron” gas such as argon. The influence of increased thermionic emission on the discharge current is also studied. © 1963, THE PHYSICAL SOCIETY OF JAPAN.

GalagaliThe Joshi effect is shown to exist in an electrodeless discharge in air when a central wire emits electrons. This is compared with the effects observed when irradiation is produced by ultra-violet or visible light.
