    Religious Lawyering\u27s Second Wave

    Get PDF
    Since the mid-1990s, the religious lawyering movement has expanded dramatically, receiving greater attention within the academy and the bar. As the movement enters what we term its second wave of development, this essay begins with a look back to its first wave of path-breaking scholarship and its gradual shift toward more institutionalized structures and programs. It argues that the predominant characteristic of first-wave religious lawyering scholarship was to claim a space within the professional conversation for lawyers to bring religious values to bear on their work. The essay then predicts that in the second wave religious lawyering conversations and scholarship will increasingly move beyond the question of whether lawyers should bring religious values to bear on their work, toward the difficult issues of how this should be done. It concludes with a glance toward the ways in which international horizons might bring new and refreshing challenges to the religious lawyering movement

    Isotope separation using metallic vapor lasers

    Get PDF
    The isotope U235 is separated from a gasified isotope mixture of U235 and U238 by selectively exciting the former from the ground state utilizing resonant absorption of radiation from precisely tuned lasers. The excited isotope is then selectively ionized by electron bombardment. It then is separated from the remaining isotope mixture by electromagnetic separation

    Application of the scalar and vector potentials to the aerodynamics of jets

    Get PDF
    The applicability of a method based on the Stokes potentials (vector and scalar potentials) to computations associated with the aerodynamics of jets was examined. The aerodynamic field near the nozzle could be represented and that the influence of a nonuniform velocity profile at the nozzle exit plane could be determined. Also computations were made for an axisymmetric jet exhausting into a quiescient atmosphere. The velocity at the axis of the jet, and the location of the half-velocity points along the jet yield accurate aerodynamic field computations. Inconsistencies among the different theoretical characterizations of jet flowfields are shown

    Abstract The necessity for the development of repeatable, efficient, and accurate monitoring of land cover change is paramount to successful management of our planet’s natural resources. This study evaluated a number of remote sensing methods for classifying land cover and land cover change throughout a two-county area in northeastern Oregon (1986 to 2011). In the past three decades, this region has seen significant changes in forest management that have affected land use and land cover. This study employed an accuracy assessment-based empirical approach to test the optimality of a number of advanced digital image processing techniques that have recently emerged in the field of remote sensing. The accuracies are assessed using traditional error matrices, calculated using reference data obtained in the field. We found that, for single-time land cover classification, Bayes pixel-based classification using samples created with scale and shape segmentation parameters of 8 and 0.3, respectively, resulted in the highest overall accuracy. For land cover change detection, using Landsat-5 TM band 7 with a change threshold of 1.75 standard deviations resulted in the highest accuracy for forest harvesting and regeneration mapping

    340 years of atmospheric circulation characteristics reconstructed from an eastern Antarctic Peninsula ice core

    Copyright @ 2006 American Geophysical Union (AGU)Precipitation delivery mechanisms for Dolleman Island (DI), located off the east coast of the Antarctic Peninsula, are investigated using reanalysis and back trajectory data. The Southern Annular Mode (SAM) and ENSO are both shown to influence precipitation delivery and event size. Precipitation delivery variability is compared against the interannual variation of chemical data from two DI ice cores. Nitrate concentration in the cores is strongly linked with the ratio of easterly to westerly back trajectories arriving at DI, as described by a Cross-Peninsula Index (CPI) defined in this paper. This CPI is used subsequently to reconstruct the atmospheric circulation characteristics for the 340-year ice core record. The analysis highlights a period of increased easterlies during 1720–1780 and an increase in westerlies for 1950–1980, the latter concomitant with a positive SAM trend and western Peninsula warming. The reconstruction also reveals periods when polynyas may have been present in the Weddell Sea

    Fusion of neurohypophyseal membranes in vitro

    Get PDF
    Freeze cleaving electron microscopy has shown that fusion of isolated secretory vesicles from bovine neurohypophyses was induced by Ca 2+ in micromolar concentrations. Mg 2+ and Sr 2+ were ineffective. Mg 2+ inhibited Ca 2+-induced fusion. In suspensions containing secretory vesicles as well as sheets of cell membrane, release of vasopressin parallel to intervesicular fusion of secretory vesicles with sheets of cell membrane was observed after exposure to Ca 2+. Mg 2+ and Sr 2+ were ineffective in replacing Ca 2+ as trigger for fusion or vasopressin release. Intervesicular fusion and exocytotic profiles were observed when isolated neurohypophyses or neurosecretosome were exposed to cold

    Defects in MgO and ZnSe

    This thesis describes the transmission electron microscope investigations of two unrelated materials, namely MgO and ZnSe. AS grown crystals of MgO have been found to contain several interesting configurations of precipitates on grown-in dislocations. An arrangement not previously reported has been found in which precipitates are located at the extremities in the [100] projection of a prismatic dislocation loop on a {100} plane. Some of the platelet shaped precipitates have been identified by electron diffraction as calcium stabilised zirconia in agreement With earlier work, but the identity of the spherical ones has still not been established. The application of reflection electron microscopy to the study of etched surfaces is demonstrated. A study of neutron damaged MgO is reported in which the effects of post-irradiation annealing treatment in the temperature range from 1100 to 1800ºC are described. The most important finding of this aspect of the work concerns the growth of cuboidal cavities in material irradiated with a dose exceeding 10 (^20) n v t. These defects are nucleated on annealing at 1500ºC for an hour in an ambient of argon and most of their growth does not occur until the annealing temperature exceeds about 1600ºC. Electron spin resonance studies of the same samples indicate that the nucleation of cavities is accompanied by a conversion of iron ions from the divalent to the trivalent state in octahedral symmetry and that most of the cavity growth does not occur until these trivalent ions become associated with vacancies. A mechanism to account for the role of iron in the cavity growth process is proposed. In the second part of this work it is shown that the major defects occurring in ZnSe are long thing ortho-twins. This study is supplemented by an investigation of zinc sulpho-selenide crystals which are found to contain narrower twins and, in addition, groups of long intrinsic stacking faults, and some polytypic regions. The fact that the stacking faults in mixed crystals are exclusively intrinsic in nature and that they usually occur in groups in which each fault has the same slip vector suggests that they owe their origin to a slip process arising from post-growth stress. An explanation based on the more covalent nature of the bonding in ZnSe and involving a stress relieving mechanism is proposed to account for the long ortho-twins being favoured in this material. Some preliminary results of ion beam damage in ZnSe samples prepared by ion thinning are discussed

    Symptomatic adrenal insufficiency during inhaled corticosteroid treatment

    Get PDF
    Symptomatic adrenal insufficiency, presenting as hypoglycaemia or poor weight gain, may occur on withdrawal of corticosteroid treatment but has not previously been reported during inhaled corticosteroid treatment. This case series illustrates the occurence of clinically significant adrenal insufficiency in asthmatic children while patients were on inhaled corticosteroid treatment and the unexpected modes of presentation. General practitioners and paediatricians need to be aware that this unusual but acute serious complication may occur in patients treated
