    Structure of Saturn's rings: Optical and dynamical considerations

    Get PDF
    The photometric phase curves of Saturn's rings are considered, as well as a conflict between dynamical and photometric models of the rings. The dependence of ring brightness on angular separation of the earth and sun as viewed from Saturn is discussed. The nonlinear brightness surge is interpreted. Some quantitative calculations were carried out for bodies in and near the asteroidal belt. Predicted density profiles of the ring obtained with Mimas in an eccentric orbit and in a circular orbit are also included

    Orbit improvement of the satellites of the outer planets

    Data reduced from 127 plates showing Jupiter's and Saturn's satellites in the interval 1972 to 1974 are available on computer cards in the form of (O-C) residuals. Initial orbit calculations and several later orbit improvements for Jupiter XIII (Leda) culminated in an extended ephemeris for Leda to the year 2000. The possible existence of several small satellites just outside Saturns rings was predicted. De Sitter's incomplete theory for the motion of the Galilean satellites was reviewed and an outline for a revised, complete theory was developed. Observations of nearly 100 relative positions of the Galilean satellite with a mean accuracy of about 100 km (0.03 arc sec) were used to improve Sampson's theory for these satellites. Results were published on (1) a long term upper limit to Jupiter's orbital eccentricity; (2) deviation of an accurate modern value of the ellipticity of Uranus from balloon-borne images and consequent evaluation of the planet's rotation rate; and (3) identification of features in Saturn's rings as produced by heretofore undetected tesseral harmonics of Saturn's gravitational field

    Unsteady transition measurements on a pitching three-dimensional wing

    Get PDF
    Boundary layer transition measurements were made during an experimental study of the aerodynamics of a rectangular wing undergoing unsteady pitching motions. The wing was tested at chordwise Mach numbers between 0.2 and 0.6, at sweep angles of 0, 15, and 30 deg, and for steady state, sinusoidal, and constant pitch rate motions. The model was scaled to represent a full size helicopter rotor blade, with chord Reynolds numbers between 2 and 6 x 10(exp 6). Sixteen surface hot-film gages were located along three spanwise stations: 0.08, 0.27, and 0.70 chords from the wing tip. Qualitative heat transfer information was obtained to identify the unsteady motion of the point of transition to turbulence. In combination with simultaneous measurements of the unsteady surface pressure distributions, the results illustrate the effects of compressibility, sweep, pitch rate, and proximity to the wing tip on the transition and relaminarization locations

    Perkembangan Interpretasi “Ke Belakang Tabir” (Ibr. 6:19, 20) Di Dalam Gereja Masehi Advent Hari Ketujuh

    In the study of the heavenly sanctuary and Christ's ministry in it, theinterpretation of the phrase “within the veil” (Heb. 6:19-20) and its implicationshave become one of crucial contentious theological issues among interpreterswithin the Seventh-day Adventist (SDA) Church. In the 160 year history of theSDA Church, there have been crucial theological debates on the interpretation ofthe phrase. Many SDA Church administrators, ministers, and scholars haveagreed and disagreed with one another on the interpretation of the phrase and itsimplications. The debate over the interpretation of the phrase "within the veil"among Adventist scholars has resulted in the proposition of differentinterpretations among Adventist theologians. The main question this studyseeks to answer is, How have the various interpretations of the phrase “withinthe veil” (Heb. 6:19-20) been developed within the SDA Church history? What,then, are the implications of each different interpretation in the study of theheavenly sanctuary and Christ's intercessory ministry in the heavenly sanctuary

    Distributed Queries for Quality Control Checks in Clinical Trials

    Get PDF
    Operational Quality Control (QC) checks are standard practice in clinical trials and ensure ongoing compliance with the study protocol, standard operating procedures (SOPs) and Good Clinical Practice (GCP). We present a method for defining QC checks as distributed queries over case report forms (CRF) and clinical imaging data- sources. Our distributed query system can integrate time-sensitive information in order to populate QC checks that can facilitate discrepancy resolution workflow in clinical trials

    Influencing Legislation for Juveniles in the Adult Judicial System: A Phenomenological Examination of Legal Advocates

    INFLUENCING LEGISLATION FOR JUVENILES IN THE ADULT JUDICIAL SYSTEM: A PHENOMENOLOGICAL EXAMINATION OF LEGAL ADVOCATES Krista Franklin Antioch University Seattle Seattle, WA This phenomenological study explores the lived experience of Washington State lawmakers and legal activists regarding their involvement in passing Washington State Senate Bill 5064 in February 2014. In response to the 2012 landmark federal Supreme Court decision, Miller v. Alabama, Senate Bill 5064 reduced the number of crimes for which juveniles could be sentenced as adults to life without parole. Six interviewees were selected from those who testified in Olympia, WA. Individual interviews were conducted in an open-ended style. Participants were asked questions about their motivation for getting involved in this bill, and asked to describe their experience. The purpose of the study is to inform those in the fields of psychology and law in order to advocate and support young offenders who are being underserved by the court system.
