The SIMPLE T-scope

THE SCOPE OF CORNEAL GRAFTING*t

IN considering corneal grafting it must surely be in the thoughts of all of us that we are offering our own special tribute as ophthalmologists to the pioneer work of our colleague and President, Mr. Tudor Thomas. For it was in Cardiff that he carried out that experimental and clinical work which not only inspired ophthalmic surgeons in many parts of the world to study corneal grafting, but whi...

The Scope of Man's Free Will

The word-superiority effect does not require a T-scope.

Six experiments examined the possibility of obtaining a word-superiority effect (WSE) without the use of brief stimulus exposures or a poststimulus mask. In each experiment, subjects were presented a stimulus string and two alternative strings that differed by a single letter (Reicher, 1969). The alternatives and stimulus remained in view until subjects responded, and subjects were under no pre...

A simple T-piece.

THE value of the T-piece principle in reducing the resistance an anaesthetic apparatus offers to respiration is well established. Unfortunately the commonly used Ayre's (1937) T-piece cannot be connected directly to the endotracheal tube. The angled connectors and pieces of rubber tubing which must be interposed markedly increase the resistance of the apparatus to respiration. To overcome this ...
