[Letter from Cassandra Broadus to Janyce Greenwood, Febraury 19, 1991]
Photocopy of a letter from Cassandra Broadus, North Texas Institute for Educators on the Visual Arts, to Janyce Greenwood, teacher at Pilot Point Elementary School. In regards to Broadus's visitation to Greenwood's classroom. Broadus writes that she enjoyed working with Greenwood's students and seeing how they participate in their art lessons, however, Broadus would like to condense the time span by rearranging the workflow. Broadus says that she will visit the school again and bring materials that Greenwood could use in the classroom.

Development of improved iron Fischer-Tropsch catalysts
The objective of proposed research is development of catalysts with enhanced slurry phase activity and better selectivity to fuel range products, through a more detailed understanding and systematic studies of the effects of pretreatment procedures and promoters/binders (silica) on catalyst performance.

Ground wave propagation of a video pulse source: Part 2
In a previous paper we developed a simple model describing the far-field from a video-pulse source near the ground and for grazing incidence. We report here on a recent field test in which we attempted to verify the model. Our results show quantitative agreement with the model for most of the tested parameter space. We have also extended our model to include all elevation angles, including up to vertical. The computed engagement envelope shows three distinct regions: At grazing angles the field is small and diminishes to near zero at the earth's surface; at low-to moderate angles strong lobing occurs; at high angles the video-pulse field approaches its free-space form. 6 refs., 16 figs.

Selective generation and extraction of low emittance electrons from plasmas: A new concept for E-beam cathodes
It is shown that hollow cathode discharges can operate in a mode characterized by a two-component electron energy distribution: bulk electrons with a thermal distribution with a temperature of a few electron volts, and a component of fast electrons with an energy of about 30 eV and a thermal spread of about 0.1 eV. Measurements of both parallel and perpendicular energy spreads confirm the existence of fast, low energy spread electrons. Selective extraction of these electrons can form the basis of a high current, high brightness electron gun which could be well suited for EBIS applications. 8 refs., 4 figs., 1 tab.

Accelerometer and strain gage evaluation
This document describes the method developed by Sandia National Laboratories (SNL) to evaluate transducer used in the design certification testing of nuclear material shipping packages. This testing project was performed by SNL for the Office of Civilian Radioactive Waste Management (OCRWM). This evaluation is based on the results of tests conducted to measure ruggedness, failure frequency, repeatability, and manufacturers' calibration data under both field and laboratory conditions. The results of these tests are provided and discussed. The transducer were selected for testing by surveying cask contractors and testing facilities. Important insights relating to operational characteristics of accelerometer types were gained during field testing. 11 refs., 105 figs., 16 tabs.
