Internal Mobilities in the Molten Binary Systems (Tl, K)NO₃ and (Tl, Cs)NO₃

Abstract

Ratios of internal cation mobilities in the molten binary systems (Tl, K)NO a and (Tl, Cs)N0 3 have been measured by the Klemm method. From these and the data available on the densities and electric conductivities, the internal mobilities b have been calculated. While generally in the mixtures of T1N0 3 with alkali nitrates at constant temperature the conductivities and internal mobilities decrease with increasing molar volume, in (Tl, K)N0 3 they decrease with decreasing molar volume. This is explained by the high polarizability of the Tl + ions.

Evaluation of laryngoscopic view, intubation difficulty and sympathetic response during direct laryngoscopy in sniffing position versus simple head extension: a clinical comparative study

“…In addition the sum of the angle between pharyngeal axis and the laryngeal axis and that between mouth axis and the pharyngeal axis was least in the sniffing position suggesting an advantage of the sniffing position over the simple head extension position. This study involved non anaesthetized volunteers and the laryngoscope blade was not used.Chow HC [12] further investigated the concepts of three axes and concluded that there is only involvement of two axes "oral and pharyngeal" and "the tongue". All these studies however pointed out that the angle between laryngeal axis and the line of vision was detected in sniffing as well as simple head extension position.…”
