Photocopy of a letter from Nancy Reynolds, Project Coordinator of North Texas Institute for Educators on the Visual Arts to Museum Educations, in regards to the NTIEVA Newsletter. Reynolds requests of the museums educators, contributions for the newsletters: regular columns, details about an exhibit, education programs or guests speakers. Reynolds writes that they're trying to publish four newsletters a year so she would like their contributions or articles as soon as possible. Reynolds has also included a call for "The Docent Educator" and has included with her letter their guidelines for submissions.

Each node in a message-passing multicomputer typically has several communication links. However, the maximum aggregate communication speed of a node is often less than the sum of its individual link speeds. Such computers are called node bandwidth limited (NBL). The NBL constraint is important when choosing algorithms because it can change the relative performance of different algorithms that accomplish the same task. This paper introduces a model of communication performance for NBL computers and uses the model to analyze the overall performance of three algorithms for vector combining (global sum) on the Intel Touchstone DELTA computer. Each of the three algorithms is found to be at least 33% faster than the other two for some combinations of machine size and vector length. The NBL constraint is shown to significantly affect the conditions under which each algorithm is fastest.

Letter from Thelma Rice to Mary H. Langford stating that she received Langford's letter about the appropriateness of The Links, Inc. holding an expensive gala during a time of economic hardship. Although she understands Langford's concerns, the gala is a tradition for which planning began several years ago. She is not sure whether plans for the gala can be altered at this point but will make sure her concerns are discussed with the national director.

The results of the Tween 80-solvated Ames testing of six mild gasification samples indicate significant mutagenic activity only in the composite materials (MG-119 and MG-120), previously suspected from the DMSO-solvated assays, which had shown some variable but ultimately insignificant mutagenic responses. The activity of these samples from the Tween 80-solvated assays was quite low when compared to either the positive controls or the SRC-II HD coal-liquefaction reference material. The class of mutagenic activity expressed by these samples solvated in Tween 80 was that of an indirect-acting, frameshift mutagen(s) since significant activity was found only on tester strain TA98 in the presence of the metabolic activation fraction (S9). Because DMSO and other solvents have been shown to affect the mutagenic activity of certain pure chemicals, the possibility of solvent/mutagen interactions in complex mixtures such as coal-derived liquids exists. Thus, the testing of the genotoxic activity of undefined, chemically complex compounds may require the use of at least two solvent systems to reduce the possibility of artifactual findings. 10 refs., 4 tabs.
