    Excerpt: The technique of trap-nesting for wasps and bees by putting out strips of wood having a hole bored in one end is not exactly new, but only within the last 15 years has it been widely employed in this country. This new book by Karl V. Krombein, chairman of the Department of Entomology at the U.S. National Museum, reveals how enormously productive the technique can be. It is, of course, useful only for species that normally nest in hollow twigs. Species that bore in pith (such as many crabronine wasps) do not usually accept the traps , nor do groundnesters (which make up the majority of wasps and bees)

    In-flight friction and wear mechanism

    Get PDF
    A unique mechanism developed for conducting friction and wear experiments in orbit is described. The device is capable of testing twelve material samples simultaneously. Parameters considered critical include: power, weight, volume, mounting, cleanliness, and thermal designs. The device performed flawlessly in orbit over an eighteen month period and demonstrated the usefulness of this design for future unmanned spacecraft or shuttle applications

    Integrable Lattice Models for Conjugate An(1)A^{(1)}_n

    Full text link
    A new class of An(1)A^{(1)}_n integrable lattice models is presented. These are interaction-round-a-face models based on fundamental nimrep graphs associated with the An(1)A^{(1)}_n conjugate modular invariants, there being a model for each value of the rank and level. The Boltzmann weights are parameterized by elliptic theta functions and satisfy the Yang-Baxter equation for any fixed value of the elliptic nome q. At q=0, the models provide representations of the Hecke algebra and are expected to lead in the continuum limit to coset conformal field theories related to the An(1)A^{(1)}_n conjugate modular invariants.Comment: 18 pages. v2: minor changes, such as page 11 footnot

    Spectral Measures for Sp(2)Sp(2)

    Get PDF
    Spectral measures provide invariants for braided subfactors via fusion modules. In this paper we study joint spectral measures associated to the compact connected rank two Lie group SO(5)SO(5) and its double cover the compact connected, simply-connected rank two Lie group Sp(2)Sp(2), including the McKay graphs for the irreducible representations of Sp(2)Sp(2) and SO(5)SO(5) and their maximal tori, and fusion modules associated to the Sp(2)Sp(2) modular invariants.Comment: 41 pages, 45 figures. Title changed and notation corrected. arXiv admin note: substantial text overlap with arXiv:1404.186
