Alteration and Oxidiation of an Olivine Lamprophyre Dike from Southern Utah, USA: An Analog for Mars

We report on oxidized basaltic dike intrusions on the Colorado Plateau as analog for Martian basalt oxidation

International photovoltaic program. Volume 2: Appendices

The results of analyses conducted in preparation of an international photovoltaic marketing plan are summarized. Included are compilations of relevant statutes and existing Federal programs; strategies designed to expand the use of photovoltaics abroad; information on the domestic photovoltaic plan and its impact on the proposed international plan; perspectives on foreign competition; industry views on the international photovoltaic market and ideas about the how US government actions could affect this market;international financing issues; and information on issues affecting foreign policy and developing countries

Effect of Breed, Sex, and Final Weight on Feedlot Performance, Carcass Characteristics, and Meat Palatability of Lambs

The objective of this project was to study the effect of slaughter weight (heavy vs light), sex (ram vs wether) and breed (Targhee vs Suffolk x Targhee) of lambs on feedlot performance, carcass characteristics and palatablity attributes. In addition, year (1975 vs 1976) and type of birth (single vs multiple) were included in the analysis

Reporting Expertise in Agricultural Communications, Education, Extension, and Leadership Research: The Development of an Expertise Rubric

This exploratory quantitative study assessed 149 behaviors, characteristics, and techniques considered indicative of expertise to determine what social scientists in Agricultural Communications, Education, Extension, and Leadership (ACEEL) disciplines value. A total of 731 social scientists from 25 land-grant universities across the United States surveyed in the fall of 2018 served as the population for this study. Using Principal Component Analysis (PCA), 10 constructs describing expertise were identified. A list of the 10 constructs was presented to faculty representing the ACEEL disciplines who helped determine what the constructs collectively measured, resulting in a label for each construct. The behaviors, characteristics, and techniques of the highest scoring constructs were used to create a rubric to assist social scientists in the systematic and intentional selection and description of the qualifications and expertise of individuals asked to serve as coders (Content Analysis), expert panelists (the Delphi method), and any contributor to social science studies in ACEEL disciplines. Use of the rubric would improve the overall consistency and transparency in how qualifications of expertise are reported in academic publications

The laboratory telerobotic manipulator program

New opportunities for the application of telerobotic systems to enhance human intelligence and dexterity in the hazardous environment of space are presented by the NASA Space Station Program. Because of the need for significant increases in extravehicular activity and the potential increase in hazards associated with space programs, emphasis is being heightened on telerobotic systems research and development. The Laboratory Telerobotic Manipulator (LTM) program is performed to develop and demonstrate ground-based telerobotic manipulator system hardware for research and demonstrations aimed at future NASA applications. The LTM incorporates traction drives, modularity, redundant kinematics, and state-of-the-art hierarchical control techniques to form a basis for merging the diverse technological domains of robust, high-dexterity teleoperations and autonomous robotic operation into common hardware to further NASA's research

A biomechanical model of anther opening reveals the roles of dehydration and secondary thickening

Understanding the processes that underlie pollen release is a prime target for controlling fertility to enable selective breeding and the efficient production of hybrid crops. Pollen release requires anther opening, which involves changes in the biomechanical properties of the anther wall. In this research, we develop and use a mathematical model to understand how these biomechanical processes lead to anther opening

Detailed computational procedure for design of cascade blades with prescribed velocity distributions in compressible potential flows

A detailed step-by-step computational outline is presented for the design of two-dimensional cascade blades having a prescribed velocity distribution on the blade in a potential flow of the usual compressible fluid. The outline is based on the assumption that the magnitude of the velocity in the flow of the usual compressible nonviscous fluid is proportional to the magnitude of the velocity in the flow of a compressible nonviscous fluid with linear pressure-volume relation
