Progress with Adaptive Optics Testbeds at the UCO/Lick Observatory Laboratory for Adaptive Optics

We report on experimental results with adaptive optics testbeds at the UCO/Lick Observatory. One testbed is dedicated to high contrast AO imaging and is a prototype for a ground-based extrasolar planet imager for the Gemini telescope. The second testbed is dedicated to developing concepts and architectures for multilaser guidestar tomography in wide-field AO applications. Such systems are now u...

Pierre Auger Observatory: Status Report

The Pierre Auger Observatory is a large international effort to provide measurements of extensive air showers (EAS) initiated in the upper atmosphere by cosmic rays with energies above 10 eV , the Ultra High Energy Cosmic Rays (UHECR’s). The explanations for the origin, acceleration processes and composition of the UHECR’s face theoretical and experimental difficulties, due to the extremely low...

A Simple Means of Preventing Spider-Lick

We gladly took the opportunity represented by a large collection of the insects that were forwarded from the same source to try out the hypothesis. A powerful tincture prepared from the specimens and matured since May 1938 was used for the experiments on two volunteers. In each experiment approximately equal quantities of the fluid were used for it and for the control. Experiment I.?In the firs...

Paleontologic Investigations at Big Bone Lick State Park, Kentucky: A Preliminary Report.

The Big Bone Lick area in Kentucky, the first widely known collecting locality for vertebrate fossils in North America, is being investigated for further faunal and geologic evidence. Mammal bones, ranging in age from Wisconsin (Tazewell?) to Recent, were recovered in 1962 from four different faunal zones in two terrace fills.
