    Stability of structural rings under uniformly distributed radial loads

    Get PDF
    Energy method analysis establishes parameters governing stability of circular rings acted upon by constant, uniformly distributed loads. Energy method is used so that nonlinear behavior of structure before buckling can be accounted for. Method affords conceptually superior basis for analyzing the axisymmetric deviation mode

    Food Plant and Distribution of \u3ci\u3eMeligethes Saevus\u3c/i\u3e (Coleoptera: Nitidulidae)

    Get PDF
    Meligethes saevus (Coleoptera: Nitidulidae) is here reported to be a spe- cialist on its food plant Onosmodium molle (Boraginaceae). The geographic distributions of these taxa are discussed. This is the first report of M. saevus from Wisconsin

    The dependency diagram of a mixed integer linear programme

    Get PDF
    The Dependency Diagram of a Linear Programme (LP) shows how the successive inequalities of an LP depend on former inequalities, when variables are projected out by Fourier- Motzkin Elimination. This is explained in a paper referenced below. The paper, given here, extends the results to the Mixed Integer case (MILP). It is shown how projection of a MILP leads to a finite disjunction of polytopes. This is expressed as a set of inequalities (mirroring those in the LP case) augmented by correction terms with finite domains which are subject to linear congruences

    BACK TO THE BASICS: A NEW CHALLENGE FOR THE BLACK CHURCH

    Get PDF
    The development of the Black community in America witnessed the Black Church exercising the unique function of assisting Blacks to gain a measure of economic strength. The opinion is ventured by Fordham that one of the most powerful and influential institutions to evolve within the Black community in the post-Civil War era was the Black Church. It was more than a religious institution: it was social, political, and economic institution all in one. Its early mutual aid societies cared for the sick, aged, and disabled; buried the dead of indigent families; provided financial support for widows and orphans; made loans; and provided many related community services. In two of his earlier works, DuBois held this same view that the Black Church was more than a religious institution. Defining the major functions of the church within the context of the Black community, he included the roles of setting moral standards, promoting education, working for social uplift of the race, building collective economic power, and providing opportunities for social interaction and recreation

    Notes on the Life Histories of \u3ci\u3eChlosyne\u3c/i\u3e (Lepidoptera: Nymphalidae) and \u3ci\u3eAgrypon\u3c/i\u3e (Hymenoptera: Ichneumonidae)

    Ambrosia trifida is reported for the first time as a larval food plant of Chlosyne nycteis. Chlosyne nycteis and C. harrisii are reported as hosts of Agrypon prismaticum and A. alpinum, respectively; the first report of wasps in Agrypon parasitizing species in Nymphalidae

    New Food Plants and First Wisconsin Records of \u3ci\u3ePublilia Modesta\u3c/i\u3e Var. \u3ci\u3eBrunnea\u3c/i\u3e (Hemiptera: Membracidae)

    Get PDF
    Publilia modesta var. brunnea was found feeding on 14 species of Aster­aceae at three sites in three Wisconsin counties in 1994-1996. This is the first report of P. modesta using these plants and of its occurrence in Wisconsin, an eastward extension of its reported distribution

    \u3ci\u3eLongitarsus Melanurus\u3c/i\u3e (Coleoptera: Chrysomelidae) Reproduces on \u3ci\u3eOnosmodium Molle\u3c/i\u3e (Boraginaceae)

    (excerpt) Longitarsus melanurus (Melsheimer) was first associated with Onosmodium Michx. by Popenoe (1877) in Kansas where the sole species is O. molle Michx. (Great Plains Flora Assn. 1986). Recent field observations over several years showed that adults of L. melanurus feed on leaves of O. molle in Wisconsin, where these beetles were collected at 43 of the 59 sites where O. molle was found growing naturally (Williams 1996)

    Three New Food Plants and First Wisconsin Record of \u3ci\u3ePublilia Reticulata\u3c/i\u3e (Hemiptera: Membracidae)

    Publilia reticulata was found feeding on the composites Silphium perfoliatum, S. integrifolium and Ambrosia trifida at eight sites in five Wisconsin counties in 1993-1995. This is the first report of P. reticulata using these plants and of its occurrence in Wisconsin
