Polynomials with prescribed bad primes

We tabulate polynomials in Z[t] with a given factorization partition, bad reduction entirely within a given set of primes, and satisfying auxiliary conditions associated to 0, 1, and infinity. We explain how these sets of polynomials are of particular interest because of their role in the construction of nonsolvable number fields of arbitrarily large degree and bounded ramification. Finally we discuss the similar but technically more complicated tabulation problem corresponding to removing the auxiliary conditions.Comment: 26 pages, 3 figure

New World Limnichinae IV. \u3ci\u3eEulimnichus\u3c/i\u3e Casey. B. Descriptions of New Species (Coleoptera: Limnichidae)

Thirteen new species of Eulimnichus are described: Eulimnichus visendus, corrinae, langleyae, coheni, improcerus, pellucidus, sharpi, incultus, rugulosus, nrsticus, acutus, subitus, and spangleri. A key to the 27 known species is included

Circular 50

In 1981 a survey was conducted to determine the kinds and amounts of pesticides used in the production of potatoes and small grains in Alaska as well as the manner in which they were used. Alaska has been asked by the United States Department of Agriculture to cooperate with the other states in a pesticide impact assessment program designed to aid the Environmental Protection Agency in predicting the consequences of its actions. This study was initaited to determine the importance of pesticides to the production of these crops. This compilation is not intended to present recommendations for pest management stuations in Alaska, and it should not be used as a pest-control guide. It simply reports surveyed information and should be used only as a reference to pesticide usage in 1981. Some general information is provided on the classification and application of each pesticide

New Michigan State Record for a Sphecine Wasp, \u3ci\u3ePodium Rufipes\u3c/i\u3e (Hymenoptera: Sphecidae)

Podium rufipes, previously unrecorded from Michigan, has been found occupy- ing trap nests in the southwestern lower peninsula

The Unified Segment Tree and its Application to the Rectangle Intersection Problem

In this paper we introduce a variation on the multidimensional segment tree, formed by unifying different interpretations of the dimensionalities of the data structure. We give some new definitions to previously well-defined concepts that arise naturally in this variation, and we show some properties concerning the relationships between the nodes, and the regions those nodes represent. We think these properties will enable the data to be utilized in new situations, beyond those previously studied. As an example, we show that the data structure can be used to solve the Rectangle Intersection Problem in a more straightforward and natural way than had be done in the past.Comment: 14 pages, 6 figure

Parasitism of \u3ci\u3eAncistrocerus Antilope\u3c/i\u3e (Hymenoptera: Eumenidae) by Leucospis Affinis (Hymenoptera: Leucospididae)

The chalcid wasp Leucospis affinis has been known to parasitize only megachilid bees. Its rare occurrence as a parasite of the eumenid wasp Ancistrocerus antilope indicates that eumenid wasps may be a large resource this chalcid is not exploiting
