Predicted and tested performance of durable TPS

The development of thermal protection systems (TPS) for aerospace vehicles involves combining material selection, concept design, and verification tests to evaluate the effectiveness of the system. The present paper reviews verification tests of two metallic and one carbon-carbon thermal protection system. The test conditions are, in general, representative of Space Shuttle design flight conditions which may be more or less severe than conditions required for future space transportation systems. The results of this study are intended to help establish a preliminary data base from which the designers of future entry vehicles can evaluate the applicability of future concepts to their vehicles

Impact of Institutional Support for Research and Development at an R1 University

This study utilizes a correlational research design to identify the relationship, if any, between institutional and external support of research and development (R&D) at an R1 University Carnegie Classification of Institutions of Higher Education R1: Very High Research Activity Doctoral University in the southeastern United States of America. Initial analyses of institutional and external R&D expenditures as reported in the National Science Foundation (NSF) Higher Education Research and Development (HERD) Survey from 2015 through 2020 did not identify any relationships between institutionally and externally funded R&D expenditures. Additionally, initial regressions were directionally split with positive correlations in 14 fields and subfields and negative correlations in 16 fields and subfields

Content of Two Upper Midwest Farm Magazines as Related to Major Types of Farming in South Dakota

The objectives of this study are to determine (1) differences in subject matter in two Midwestern farm magazines, and (2) how these magazines conformed to reader needs, based on the assumption that these needs are a reflection of the traditional types of agriculture in the area served by the publications. The magazines used in this study are: The Dakota Farmer, Aberdeen, South Dakota, and The Farmer., St. Paul, Minnesota. Comparisons, when draw, are designed to indicate a point rather than to judge or intimate that one of the magazines is better than the other. To further emphasize this point of non-endorsement, the reader\u27s attention is called to the disclaimer clause” which public agencies often use as a protective umbrella when it is necessary to mention trade or product names in printed matter. As an example: To simplify terminology, trade names of products or equipment are sometimes used. No endorsement of specific products named is intended, nor is criticism implied of products not mentioned. Ln specifying reader needs as based on traditional types of agriculture, the term needs is used mainly to include what the editors apparently think a subscriber might want in the way of specific information about various aspects or hid method or making a living. What he might want for entertainment or other purposes cannot be eliminated entirely, of course. It is well to keep in mind a longstanding principle in mass communication theory: that people expose themselves to communications that fit with their existing ideas and opinions. South Dakota is predominately an agricultural state. Livestock, including cattle, swine, sheep and poultry, accounts for almost three fourths of the agricultural income. Crops which make up most of the remaining income source include corn, wheat, oats and hay. These traditional types of agriculture--livestock and crops--in South Dakota formed the base in determining the needs of the people assumed to be the readers of the magazines used in this study--The Dakota Farmer and The Farmer, to determine types of agriculture, two basic references were used: sources of agricultural income and types of farms in the state.
