    Notes: Abstract The flow cytometry method (FCM) was employed to determine cellular DNA content of black-crowned night-heron (Nycticorax nycticorax) embryos and 10-day-old chicks collected at sites differing in types of chemical contamination. The coefficient of variation of DNA content (CV) in blood collected from embryos suggested cytogenetic damage at a site in Louisiana known to be contaminated with petroleum. Blood CV from chicks suggested genetic damage at a site in Texas also known to be contaminated with petroleum. Spleen CVs in chicks were significantly lower than respective means from the reference site. The CVs of chick blood and liver and spleen negatively correlated, suggesting recovery of spleen and liver cells after exposure to a clastogenic compound. Thus, the lower CVs may also have been indicative of genetic damage. Based on the findings of this study, FCM is a potential indicator of certain environmental contaminants in black-crowned night-herons.

    Variability in concentrations of selected trace elements in water and sediment of six acidic lakes (1987)
    Springer

    Notes: Abstract Concentrations of the trace elements aluminum, cadmium, lead, manganese, and zinc were determined in water and sediments of six acidic clear-water lakes (pH 3.6–6.2) in northwestern New Jersey. Levels of aluminum, lead, and zinc in the water column were sharply elevated in the most acidic lakes, with values similar to acidified systems elsewhere. Seasonal fluctuations occurred, with lead displaying peak concentrations in all lakes during the fall sampling period. Analyses of core samples of lake sediment indicated that while lead concentrations exhibited a typical sharp increase in most recent sediments, cadmium and zinc levels in the upper layers were substantially lower than values reported for similar systems elsewhere. As expected, manganese concentrations generally decreased in the upper sediment layers in the acidic lakes, while aluminum varied dramatically between systems.

    Notes: Abstract The object of this paper is to study how many essentially different common transversals a family of convex sets on the plane can have. In particular, we consider the case where the family consists of pairwise disjoint translates of a single convex set.

    Notes: Abstract. When C is a ball in ${\Bbb R}^d$ and S is the sphere $\partial C$ , we say that S supports a convex body B if S intersects B and either $B\subseteq C$ (then S is a far support) or the interior of C is disjoint from B (then S is a near support). The focus here is on common supports for a system $\cal B$ of d+1 bodies in ${\Bbb R}^d$ such that for each way of selecting a point from each member of ${\cal B}$ , the selected points are affinely independent and hence form the vertex-set of a d-simplex. The main result asserts that if $({\cal B}',{\cal B}'')$ is an arbitrary partition of ${\cal B}$ , then there exists a unique Euclidean sphere that is simultaneously a near support for each member of ${\cal B}'$ and a far support for each member of ${\cal B}''$ .

    Notes: Abstract We construct a family ofn disjoint convex set in ℝ d having (n/(d−1)) d−1 geometric permutations. As well, we complete the enumeration problem for geometric permutations of families of disjoint translates of a convex set in the plane, settle the case for cubes in ℝ d , and construct a family ofd+1 translates in ℝ d admitting (d+1)!/2 geometric permutations.

    Possible geothermal resources in the Coast Plutonic Complex of southern British Columbia, Canada (1978)

    Notes: Abstract In southern British Columbia the terrestrial heat flow is low (44 mW m−2) to the west of the Coast Plutonic Complex (CPC), average in CPC (50–60 mW m−2),and high to the east(80–90 mW m−2). The average heat flow in CPC and the low heat generation (less than 1 μW m−3) indicate that a relatively large amount of heat flows upwards into the crust which is generally quite cool. Until two million years ago the Explorer plate underthrust this part of the American plate, carrying crustal material into the mantle. Melted crustal rocks have produced the inland Pemberton and Garibaldi volcanic belts in the CPC. Meager Mountain, a volcanic complex in the CPC 150 km north of Vancouver, is a possible geothermal energy resource. It is the product of intermittent activity over a period of 4 My, the most recent eruption being the Bridge River Ash 2440 y B.P. The original explosive eruption produced extensive fracturing in the granitic basement, and a basal explosion breccia from the surface of a cold brittle crust. This breccia may be a geothermal reservoir. Other volcanic complexes in the CPC have a similar potential for geothermal energy.

    Description / Table of Contents: Zusammenfassung Unter Benutzung des Maximumprinzips für subharmonische Funktionen werden obere Schranken angegeben für den Gradienten des Neumannschen Problems der Potential-Theorie. Diese Schranken betreffen einem gekrümmten Streifenbereich mit von Null verschiedenen Grenzdaten an einem Ende und haben zur Folge, dass der Betrag des Gradienten exponentiell mit dem Abstand von diesem Ende abfällt.
    Notes: Abstract The maximum principle for subharmonic functions is used to obtain upper bounds for the gradient in the Neumann problem of potential theory. These bounds, which concern a curvilinear strip domain having nonzero boundary data only on an end, entail an exponential decay of the gradient magnitude with distance from that end.

    Description / Table of Contents: Zusammenfassung Bekanntlich führt Fourier's klassische Theorie der Wärmeleitfähigkeit zu einer unendlich großen Ausbreitungsgeschwindigkeit lokaler Temperaturstörungen. Gurtin und Pipkin haben eine Theorie für starre Wärmeleiter mit Gedächtnis eingeführt und haben auch einen Beweis dafür gegeben, daß ihre Theorie auf eine endliche Ausbreitungsgeschwindigkeit führt. Die vorliegende Arbeit bezieht sich auf die linearisierte Form der Theorie von Gurtin und Pipkin für isotrope Leiter. Es werden Bedingungen für endliche Ausbreitungsgeschwindigkeit angegeben. Ferner wird die Eindeutigkeit der Lösungen für eine Klasse von history-value-Problemen angegeben, die durch die lineare Theorie nahegelegt werden.
    Notes: Summary It is well known that the classical theory of heat conduction, which is based upon Fourier's law, leads to infinite propagation speeds for thermal disturbances. In a recent investigation [1], Gurtin and Pipkin devised a theory appropriate to rigid heat conductors with memory, and put forth evidence that their theory gives rise in general to finite wave speeds. The present paper is concerned with the linearized version of the theory presented in [1], in the form it assumes for isotropic conductors. We arrive at conditions upon the material response functions that ensure the finiteness of the wave speeds. In addition, we establish uniqueness of solutions for a class of history-value problems suggested by the linearized theory.
