    The specification results for the finished tape properties were as follows: (1) adhesive strength (180 deg peel) on aluminum from 107 to 143 grams per centimeter (0.6 to 0.8 pounds per inch); (2) adhesive strength (180 deg peel) on stainless steel from 71 to 107 grams per centimeter (0.4 to 0.6 pounds per inch); (3) unwind resistance of 536 to 714 grams per centimeter (3 to 4 pounds per inch); (4) tensile strength minimum of 7143 grams per centimeter (40 pounds per inch); (5) elongation from 5 to 10% at break; (6) tear strength, Elmendorf from 200 to 350 grams (0.44 to 0.77 pounds); and (7) tear strength, tongue from 363 to 408 grams (0.8 to 0.9) pounds)

    Development of the Learners’ Management Philosophy in a Critical Management Studies Course

    Get PDF
    Study examined the pivotal factors of a CMS course, which shaped the learners’ development. The findings suggest that the educator is only one aspect of the learning process and that the ability of the learner to use experience to bridge to new critical concepts and the role of discussions are important

    Magnetic field structure due to the global velocity field in spiral galaxies

    Full text link
    We present a set of global, self-consistent N-body/SPH simulations of the dynamic evolution of galactic discs with gas and including magnetic fields. We have implemented a description to follow the evolution of magnetic fields with the ideal induction equation in the SPH part of the Vine code. Results from a direct implementation of the field equations are compared to a representation by Euler potentials, which pose a div(B)-free description, an constraint not fulfilled for the direct implementation. All simulations are compared to an implementation of magnetic fields in the Gadget code which includes also cleaning methods for div(B). Starting with a homogeneous seed field we find that by differential rotation and spiral structure formation of the disc the field is amplified by one order of magnitude within five rotation periods of the disc. The amplification is stronger for higher numerical resolution. Moreover, we find a tight connection of the magnetic field structure to the density pattern of the galaxy in our simulations, with the magnetic field lines being aligned with the developing spiral pattern of the gas. Our simulations clearly show the importance of non-axisymmetry for the evolution of the magnetic field.Comment: 17 pages, 18 figure

    Practical theories for service life prediction of critical aerospace structural components

    Get PDF
    A new second-order theory was developed for predicting the service lives of aerospace structural components. The predictions based on this new theory were compared with those based on the Ko first-order theory and the classical theory of service life predictions. The new theory gives very accurate service life predictions. An equivalent constant-amplitude stress cycle method was proposed for representing the random load spectrum for crack growth calculations. This method predicts the most conservative service life. The proposed use of minimum detectable crack size, instead of proof load established crack size as an initial crack size for crack growth calculations, could give a more realistic service life

    What’s the monetary value of your premerchantable timber?

    Get PDF
    Premerchantable timber is not yet merchantable-in most cases this means the trees are too small to be sold for pulpwood or other commercial products. Sometimes referred to as \u27\u27precommercial or \u27\u27immature, timber stands with average tree diameters less than five inches occupy over 50 million acres in the South-an area roughly the size of North and South Carolina combined

    Bridging Racial Divisions in Urban Graduate Education

    Get PDF
    One of our core beliefs is that we, as adult educators, are responsible for providing environments that include spaces where dialogues of race and racism occur, which facilitate the learning and transformation of students, our practice and ourselves. However, as white faculty we find ourselves caught in a fabric woven of power and privilege that constantly challenges us to recognize how we live in the paradox of contributing to the ongoing nature of racism as we simultaneously try to transform it. The purpose of this roundtable discussion is to wrestle with this paradox and encourage dialogue and perspectives among adult educators

    Transforming Learners’ Engagement: Reflections on a Continuing Medical Education Program

    Continuing education at most medical meetings rely heavily on didactic methodologies. Attendees expect this approach in a Continuing Medical Education (CME) program and are surprised when another approach is taken. This roundtable paper briefly examines how adult educators can begin changing the culture of CME for physicians
