(
Qatar University
, 1985 , Article)
The genera Enenterum and Pseudocreadium are reviewed. It is suggested that Pseudocreadium indicum Madhavi, 1972 should be considered a synonym of P. balistes Nagaty, 1942. Enenterum pimelopteri Nagaty, 1942, is redescribed ...
A Short Note On The Point-Wise Summability Of The Conjugate Series Of A Fourier Series In The Norlund Sense
(
Qatar University

In this note we consider an analogous theorem of [l] in the sense of point-wise summability of the conjugate series of a Fourier series in the Norlund sense
Microdetermination Of Some Organic Nitriles Using The Cyanide Ion Selective Electrode
(
Qatar University
, 1985 , Article)
The response characteristics of the solid state cyanide ion selective electrode toward some organic nitriles are investigated. In 10 M KOH solution, the electrode exhibits near Nemstian response over the range of 10~2 to ...
