In a specimen which is transmission thin to 100 kV electrons - a sample in which X-ray absorption is so insignificant that it can be neglected and where fluorescence effects can generally be ignored (1,2) - a ratio of characteristic X-ray intensities, I1/I2 can be converted into a weight fraction ratio, C1/C2, using the equationwhere k12 is, at a given voltage, a constant independent of composition or thickness, k12 values can be determined experimentally from thin standards (3) or calculated (4,6). Both experimental and calculated k12 values have been obtained for K(11<Z>19),kα(Z>19) and some Lα radiation (3,6) at 100 kV. The object of the present series of experiments was to experimentally determine k12 values at voltages between 200 and 1000 kV and to compare these with calculated values.The experiments were carried out on an AEI-EM7 HVEM fitted with an energy dispersive X-ray detector.

Threshold Duration

Previous findings on the threshold for tones as a function of their duration have suggested that such functions may be systematically affected by sensori-neural hearing losses of cochlear origin. The present series of investigations was designed to explore this relation further and to determine also whether the amount of hearing loss present has any effect upon the results which are obtained. Preliminary studies were also carried out on a conductively impaired listener to indicate whether hearing losses of this type affect the threshold-duration function. The results indicate that the threshold-duration function is systematically affected by sensori-neural hearing losses of cochlear origin. This effect is manifested by a progressive shortening of the time constant relating threshold to duration and is not uniquely related to the amount of hearing loss present. The results obtained from the conductively impaired listener suggested that this type of hearing loss has no effect on the threshold-duration function, thereby implying that such functions may contribute significantly to the differential diagnosis of auditory disorders.

Shakespeare is well known to have set two of his plays in and around Venice: The Merchant of Venice (1596) and The Tragedy of Othello, the Moor of Venice (1603). The first is often remembered for its famous speech about “the quality of mercy,” delivered by the female lead Portia in the disguise of a legal scholar from the university town of Padua. The speech helps to spare the life of her new husband’s friend and financial backer against the claims of the Jewish moneylender Shylock. The play has raised questions for Shakespearean scholars about the choice of Venice as an open city where merchants of all nations and faiths would meet on the Rialto while the city’s Senate, composed of leading merchants, worked hard to keep it open to all and especially profitable for its merchants. Those who would like to learn more about the city’s development as a center of trade can learn much from Richard Mackenney’s new book.
