    The correlation of Skylab L-band brightness temperatures with antecedent precipitation

    Get PDF
    The S194 L-band radiometer flown on the Skylab mission measured terrestrial radiation at the microwave wavelength of 21.4 cm. The terrain emissivity at this wavelength is strongly dependent on the soil moisture content, which can be inferred from antecedent precipitation. For the Skylab data acquisition pass from the Oklahoma panhandle to southeastern Texas on 11 June 1973, the S194 brightness temperatures are highly correlated with antecedent precipitation from the preceding eleven day period, but very little correlation was apparent for the preceding five day period. The correlation coefficient between the averaged antecedent precipitation index values and the corresponding S194 brightness temperatures between 230 K and 270 K, the region of apparent response to soil moisture in the data, was -0.97. The equation of the linear least squares line is given

    The why and how of liturgical theology : Dissecting a method

    Get PDF
    Liturgical theology is a relatively new sub-discipline of theology. Despite many efforts, clarity is still lacking in both its purpose and methodology. In this study, the liturgical-theological method of luminary Kevin W. Irwin is dissected, diagrammed, and evaluated in direct response to recent calls in the academy for clarity in liturgical-theological method; the study also contributes to the ongoing conversation as to what liturgical theology is, why it matters, and how it is to be undertaken

    A concept for reducing oceanic separation minima through the use of a TCAS-derived CDTI

    Get PDF
    A concept for using a cockpit display of traffic information (CDTI), as derived from a modified version of the Traffic Alert and Collision Avoidance System 2 (TCAS 2), to support reductions in air traffic separation minima for an oceanic track system is presented. The concept, and the TCAS modifications required to support it, are described. The feasibility of the concept is examined from a number of standpoints, including expected benefits, maximum alert rates, and possible transition strategies. Various implementation issues are analyzed. Pilot procedures are suggested for dealing with alert situations. Possible variations of the concept are also examined. Finally, recommendations are presented for other studies and simulation experiments which can be used to further verify the feasibility of the concept

    The Civil Investigative Demand: A Constitutional Analysis and Model Proposal

    Get PDF
    This Note first traces the initial judicial reaction to administrative demands for information and administrative investigations and delineates the constitutional requirement set forth therein. The Note next examines the development of CIDs and analyzes decisions upholding their constitutionality. This Note contends that most courts either have incorrectly applied current administrative standards to the CID or have failed to apply such standards altogether. The analysis is broken down into six parts,each dealing with a separate constitutional basis for a CID challenge. Because most suits that contest CIDs are based on fourth amendment search and seizure issues, the bulk of this Note is dedicated to a discussion of this area. CIDs, however, do have utility as investigative devices when proper safeguards are afforded the demandee. Therefore, this Note concludes by presenting a proposed model civil investigative demand statute designed to meet the constitutional objections outlined herein

    How Clean is the Clean Room?

    In order to limit contamination and protect the integrity of search-for-life missions, spacecraft assembly clean rooms should be free of microorganisms to the extent that planetary protection guidelines require of the mission. This study monitored the bioburden of the clean room in which the Mars-destined InSight lander was being assembled. Samples of ten locations inside the clean room and one location outside were taken at monthly intervals, starting in March 2014 and scheduled to end in September 2014. Bioburden was determined using qPCR and ATP analyses with qPCR targating 16S rRNA gene copy number and ATP targating metabolic activity of microbes. Samples were treated with propidium monoazide (PMA) to selectively distinguish between viable and non-viable cells prior to DNA extraction and qPCR. Analyses of total ATP, internal ATP, and ATP as measured by a handheld device were done. Results from the first three samplings shows that the amount of both untreated and PMA treated DNA decreased significantly between the first sampling (3/21/2014) and the second sampling (5/13/2014), possibly as a result of increased assembly activity and rigorous cleaning practices. Results of the ATP analyses showed no significant changes in total ATP, but internal and handheld ATP decreased between the second and third samplings. The preliminary results indicate that the bioburden of the clean room changes inversely as a result of assembly activity and cleaning efforts. The clean room will continue to be monitored through an additional three months

    Absolute intensity of radiation emitted by uranium plasmas

    Get PDF
    The absolute intensity of radiation emitted by fissioning and nonfissioning uranium plasmas in the spectral range from 350 nm to 1000 nm was measured. The plasma was produced in a plasma-focus apparatus and the plasma properties are simular to those anticipated for plasma-core nuclear reactors. The results are expected to contribute to the establishment of design criteria for the development of plasma-core reactors
