Part 1: The Test of Time Icy winds have been blowing continuously for nine days. Jon walked slowly towards the drilling site, slapping his shoulders to keep warm. Normally he was clean shaven, but he was now thankful for having grown his beard. It has been eight hours since he last felt the warmth of the heated office, back at the base camp. Now would be the time for a nice mug of steaming hot coffee, he thought. Through the snow, which started as a blizzard at 5:00 a.m. but had now thankfully dwindled to a steady fall of snow with visibility reduced to ten meters, Jon heard the distant faint rumble of the Powertech drilling machine. The drilling had started in the morning of the fourth of N...
This volume covers reagent literature published between July 1981 and December 1982. It provides references to new reagents introduced during this period, as well as recent references to reagents included in previous volumes, focusing on reagents that open new vistas in organic synthesis.
The core use of language is in face-to-face conversation. This is characterized by rapid turn-taking. This turn-taking poses a number central puzzles for the psychology of language. Consider, for example, that in large corpora the gap between turns is on the order of 100 to 300 ms, but the latencies involved in language production require minimally between 600 ms (for a single word) or 1500 ms (for as simple sentence). This implies that participants in conversation are predicting the ends of the incoming turn and preparing in advance. But how is this done? What aspects of this prediction are done when? What happens when the prediction is wrong? What stops participants coming in too early? If...
Four years ago when we had finished our work on the first edition of our Handbook we didn't even suppose that three years later it would become necessary to greatly revise and update the material. It happened because of the following developments. 1. The invention and tremendous development of modern nonlinear optical crystals such as BBO, LBO, KTP, ZnGeP , etc. 2 2. Rapid progress in laser techniques (femtosecond CPM laser, Ti: sapphire laser, diode-pumped solid-state lasers, etc.). 3. The appearence of numerous organic crystals which can be synthesized with predictable properties. 4. Progress in the theory of nonlinear frequency conversion utilizing biaxial crystals, femtosecond pulses, et...
