Data User's Note: Apollo seismological investigations

Seismological objectives and equipment used in the passive seismic, active seismic, lunar seismic profiling, and the lunar gravimeter experiments conducted during Apollo 11, 12, 14, 15, 16, and 17 missions are described. The various formats in which the data form these investigations can be obtained are listed an an index showing the NSSDC identification number is provided. Tables show manned lunar landing missions, lunar seismic network statistics, lunar impact coordinate statistics, detonation masses and times of EP's, the ALSEP (Apollo 14) operational history; compressed scale playout tape availability, LSPE coverage for one lunation, and experimenter interpreted events types

Analysis of proposed air drying process

An air drying process has been analyzed which is intended to reduce the water vapor content of a stratospheric sample to below one part per million by weight, based upon the removal of the water as it passes through a phosphorous pentoxide absorber. The analysis indicates that the method is feasible. Dependence on ram pressure to maintain flow through the absorber appears questionable and consideration should be given to other means

Unjust Revisions: A Social Justice Framework For Technical Editing

Background: There is a lack of conceptual framework for how to develop more inclusive practices in the subfield of technical editing. Literature review: Some researchers have posited theories, like feminism and rhetorical theory, as ways to conceptualize technical editing. This piece extends that literature into social justice using Walton, Moore, and Jones\u27s 3Ps heuristic of positionality, privilege, and power. Research questions: 1. What ideologies are circulating in technical editing pedagogy? 2. How might technical editing pedagogy become more inclusive? Methodology: We conduct a rhetorical analysis of the major academic works in technical editing, including books, textbooks, and academic articles, and compare them to an established framework for social justice in technical and professional communication - the 3Ps heuristic. Results: We find that there are strong instrumentalist underpinnings to much of the current literature in technical editing, making the goal of technical editing linguistic conformity to American Standard English (ASE) at the expense of linguistic diversity. We offer a conceptual framework, the inclusive editing paradigm (IEP), to challenge that linguistic hegemony in technical editing and provide technical editors with theoretical and practical foundations for developing a more inclusive editing practice. Conclusions: More work needs to be done to shift technical editing in a more inclusive direction. We call on practitioners, academics, and users to contribute to this dialogue

Automotive Stirling engine: Mod 2 design report

The design of an automotive Stirling engine that achieves the superior fuel economy potential of the Stirling cycle is described. As the culmination of a 9-yr development program, this engine, designated the Mod 2, also nullifies arguments that Stirling engines are heavy, expensive, unreliable, demonstrating poor performance. Installed in a General Motors Chevrolet Celebrity car, this engine has a predicted combined fuel economy on unleaded gasoline of 17.5 km/l (41 mpg)- a value 50% above the current vehicle fleet average. The Mod 2 Stirling engine is a four-cylinder V-drive design with a single crankshaft. The engine is also equipped with all the controls and auxiliaries necessary for automotive operation

Application of CARS to scramjet combustion

A coherent anti-Stokes Raman spectroscopic (CARS) instrument has been developed for measuring simultaneously temperature and N2 - O2 species concentration in hostile flame environments. A folded BOXCARS arrangement was employed to obtain high spatial resolution. Polarization discrimination against the nonresonant background decreased the lower limits of O2 detectivity. The instrument has been primarily employed for validation of computational fluid-dynamics computer-model codes. Comparisons have been made to both the CHARNAL and TEACH codes on a hydrogen diffusion flame with good results

Crowdsourcing the State of the Art(ifacts)

In any field, finding the "leading edge" of research is an on-going challenge. Researchers cannot appease reviewers and educators cannot teach to the leading edge of their field if no one agrees on what is the state-of-the-art. Using a novel crowdsourced "reuse graph" approach, we propose here a new method to learn this state-of-the-art. Our reuse graphs are less effort to build and verify than other community monitoring methods (e.g. artifact tracks or citation-based searches). Based on a study of 170 papers from software engineering (SE) conferences in 2020, we have found over 1,600 instances of reuse; i.e., reuse is rampant in SE research. Prior pessimism about a lack of reuse in SE research may have been a result of using the wrong methods to measure the wrong things.Comment: Submitted to Communications AC
