Under physiological conditions, potassium channels are extraordinarily selective for potassium over other ions. However, in the absence of potassium, certain potassium channels can conduct sodium. Sodium flux is blocked by the addition of low concentrations of potassium. Potassium affinity, and therefore the ability to block sodium current, varies among potassium channel subtypes (Korn, S.J., a...

STOCK DEFINITION AND GEOGRAPHIC RANGE There are two species of pilot whales in the Western Atlantic — the Atlantic or long-finned pilot whale, Globicephala melas, and the short-finned pilot whale, G. macrorhynchus. These species are difficult to identify to the species level at sea; therefore, some of the descriptive material below refers to Globicephala sp., and is identified as such. The spec...

One of the distinctive features of multilingual Jewish cultures is the interpretation of a sacred Hebrew signifier by its phonic identity or proximity to a signifier in another language. This essay demonstrates the cultural creativity that might inhere in such “mistakes,” providing examples from three different periods—rabbinic, Hebrew-Yiddish European culture, and modern Israeli Hebrew. I n th...

The teaching and research in folklore at the Hebrew University in Israel, as in many American universities, preceded the formal establishment of a folklore department. Most of these activities were carried out by members of the Institute of Jewish Studies. The present collection of twelve essays represents, as it purports to do, the scholarly position of Jewish folk-literature at the Hebrew Uni...
