... Abstract: We present an extensive study of the radiative transfer in dusty galaxies based on Monte Carlo simulations. ... We have explored the dependence of A_l on a conspicuous set of quantities (Hubble type, inclination, dust optical thickness, dust distribution and extinction properties) for a large wavelength interval, ranging from 1250A to the K band, thus finally providing a comprehensive atlas of dust extinction in galaxies, which is electronically available. ...

In January of 1992 we drilled and measured a set of test plates testing several techniques including drilling with a carbide twist drill and drilling followed by reaming [R. Owen, et al., unpublished]. ... The test plates were 3.5" diameter 1/8" thick disks of aluminum. 50 holes were drilled in each test plate, 10 each in five concentric circles. ... This diameter was the optimal value for our plug plates determined from the 1/92 drilling tests. ...

We describe an implementation of Dynamic Queries (DQ), a recently developed method as an alternative to the perceived complicated SQL-type operations on relational databases by a very intuitive graphical interface. This prototype implementation, written within the NEMO package, uses ASCII sliders and the PGPLOT graphics interface and uses a novel interactive analysis back-end tool that is dynamically associated with the query. ...
