    Notes: Abstract The steady-state shape of a drop of liquid under the action of surface tension, gravity and centrifugal forces is determined in this paper. The governing equations are derived from a variational principle on the total energy of the droplet. The steady-state shape is assumed to be axially symmetric, which allows describing it by means of its generator curve. This is approximated by a cubic parametric spline with suitable end conditions, and unknown supporting points. These are determined via the nonlinear least-square approximation of the arising overdetermined nonlinear algebraic system of equations. The procedure is illustrated with an example from the glass industry.

    Composition of the proteinaceous gel secretion from the skin of the Arabian Gulf catfish (Arius thallasinus) (1982)
    Springer
    Marine biology 70 (1982), S. 27-33

    Topics: Biology
    Notes: Abstract The Arabian Gulf catfish Arius thallasinus excretes copious amounts of proteinaceous gel from epidermal cells when threatened or injured. As a means of investigating its biological role, this gel material has been examined to determine the nature of the secretion and its associated biological activities. Over 85% of the dry weight of the gel material is protein with small amounts of lipids, carbohydrates and nucleic acid components. Most of the protein exists as a high molecular weight aggregate of predominantly 13 500 molecular weight monomeric units. Several lytic enzyme activities are found in the gel secretion, one of which catalyzes lysis of red blood cells. Other factors induce clotting in citrate treated plasma and agglutination of red blood cells. The enzymic properties of the gel secretion resemble those of some animal venoms.

    Catfish epidermal secretions in response to threat or injury (1985)
    Springer
    Marine biology 88 (1985), S. 117-123

    ISSN: 1432-1793

    Topics: Biology
    Notes: Abstract The Arabian Gulf catfish (Arius thalassinus, Rüppell) secrete a thick layer of proteinaceous material when threatened or injured. The chemical and pharmacological properties of this material indicate that it may promote the healing of wounds. These studies suggest that the abrupt secretion of mucous-like gel in response to a perceived hazard is an externally expressed defense response; the secretion may have a primary function in healing injury beyond the commonly postulated roles of deterring predators or facilitating escape.

    Fluid source and thermal history of an epithermal vein deposit, Owen Lake, central British Columbia: evidence from bitumen and fluid inclusions (1992)
    Springer
    Mineralium deposita 27 (1992), S. 219-225 
    Details
    ISSN: 1432-1866
    Source: Springer Online Journal Archives 1860-2000
    Topics: Geosciences
    Notes: Abstract Fluid source and thermal history are determined for the barite and bitumen-bearing, early Eocene (ca. 50 Ma) polymetallic, epithermal veins of the Owen Lake deposit, central British Columbia, Canada. Carbon isotopic values for the bitumen are highly negative (δ 13 C ca −29%) indicating a probable terrigenous source, which may be 1 no older than Late Cretaceous or, 2 Eocene plant-fossil-bearing units stratigraphically above the Owen Lake deposit. Heat generated by suspected magmatic activity resulted in downflow of meteoric water and upflow of hydrothermal water, mixing at the site of deposition. Aqueous and hydrocarbon fluid inclusions occur within barite; Th of both types of inclusions indicate a temperature range of approximately 100° to 180 °C. Tm(ice) of aqueous inclusions range from −4.5 to −0.2 °C indicating a range of 7.2 to 0.4 equivalent weight percent NaCl. Parageneticaly younger bitumen has a vitrinite reflectance of 0.6% indicating maturation level in the temperature range of 80° to 120 °C, strongly suggesting a cooling thermal regime during barite and bitumen deposition, consistent with a late stage paragenesis.

    Method of delivering constant nitric oxide concentrations during full and partial ventilatory support (1995)
    Springer
    Journal of clinical monitoring and computing 11 (1995), S. 23-31 
    Details
    ISSN: 1573-2614
    Keywords: Nitric oxide, nitrogen dioxide ; mechanical ventilatory support, mechanical respiratory system model ; respiratory therapy, critical care

    Notes: Abstract Objective. The objective of our study was to evaluate the precision and safety of administering nitric oxide (NO) during full and partial ventilatory support.Methods. NO was administered either using a microprocessor-controlled servo ventilator, substituting an NO-N2 mixture for the ventilator's usual air supply or by adding an NO-N2 mixture with a constant flow at the proximal end of the tracheal tube. NO, nitrogen dioxide (NO2), and nitrous and nitric acid (HNOx) was quantified selectively with a sequential, selective, hollow tube preconcentration and chemiluminescence analysis in a respiratory system model during various modes of full and partial ventilatory support.Results. The servo valve system of the ventilator provided accurate NO concentrations during full and partial ventilatory support. Interaction of spontaneous and mechanical ventilation during partial ventilatory support resulted in irregular inspiratory flow patterns and a difference of 3.6% to 44.1% between the desired and measured inspiratory NO concentrations when NO was administered at a constant flow to the proximal end of the tracheal tube. NO2 was not detected. Small amounts of 0.6 to 0.8 ppm HNOx were detected when 80 ppm NO was administered in a humid gas mixture of 37°C in the presence of 90% oxygen.Conclusions. NO can be administered accurately without formation of NO2 during full and partial ventilatory support with the electronically controlled valve system of the ventilator. Formation of HNOx is a potential problem at high NO and O2 concentrations in the presence of moisture.

    Maternal effect of a hybrid inviability gene in Tribolium castaneum (1998)
    Springer
    Genetica 104 (1998), S. 155-159 
    Details
    ISSN: 1573-6857
    Keywords: hybrid inviability ; reproductive isolation ; speciation ; Tribolium
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract The Tribolium castaneum hybrid inviability gene, H, was selectively introgressed into a genetic background lacking H through serial paternal backcrosses. This revealed a poor viability phenotype (partial paralysis and poor control of the limbs, referred to as tremor) not present in the parent strains. Tremor cosegregated with H, but was expressed only when transmitted paternally and only when H was not also present maternally. The inferred maternal, self‐suppressive effect of H may explain nonreciprocal incompatibilty previously observed between H and H‐incompatible strains.

    Identifying genes within microdissected genomic DNA: Isolation of brain expressed genes from a translocation region associated with inherited mental illness (1995)
    Springer
    Mammalian genome 6 (1995), S. 257-262

    Notes: Abstract An improved protocol has been developed for physical enrichment of cDNA sequences by hybridization to genomic DNA. When applied to microdissection recombinants derived from a translocation breakpoint region associated with inherited mental illness, a single cycle of the procedure permitted enriched cDNAs to be visualized directly by agarose gel electrophoresis. Hybridization screening of a library of clones derived from the enriched cDNAs, employing the genomic resource as a probe, led to the identification of six novel gene fragments. This general approach to the isolation of regionally encoded genes could be applied to any subchromosomal interval as a first step towards global transcription map construction.

    Description / Table of Contents: Résumé La spécificité vis-à-vis de l'hôte et l'effet du conditionnement sur la réponse comportementale aux écailles de lépidoptères varient chez les femelles de 4Trichogramma spp. observées en essais de laboratoire. Les espècesTrichogramma nrpretiosum Riley etT. exiguum Pinto & Platner répondent faiblement aux écailles d'Ostrinia nubilalis (Hübner), par rapport à celles d'Heliothis zea (Boddie) et deManduca sexta (L.).T. maltbyi Nagaraja & Nagarkatti etT. minutum Riley ne font pas de distinction entre les écailles de ces trois hôtes. Le conditionnement avec des combinaisons variées d'écailles d'hôtes et d'œufs n'altérait pas la spécificité, mais changeait dans quelques cas la sensibilité générale aux écailles. Ces changements furent attribués à l'accoutumance, à la perte d'attirance due aux longues séquences de ponte et à l'apprentissage. En général, la réponse aux écailles semble être innée et absolument non spécifique.
    Notes: Abstract Host specificity and the effect of conditioning on a behavioral response to lepidopteran scales varied among the females of 4Trichogramma spp. observed in laboratory experiments.Trichogramma species nrPretiosum Riley andT. exiguum Pinto & Platner responded weakly toOstrinia nubilalis (Hübner) scales relative toHeliothis zea (Boddie) andManduca sexta (L.).T. maltbyi Nagaraja & Nagarkatti andT. minutum Riley did not discriminate between scales from these 3 hosts. Conditioning with various combinations of host scales and eggs did not alter host specificity, but in some cases, changed general responsiveness to scales. These were attributed to habituation, loss of appetitive drive due to long oviposition bouts, and associative learning. In general, the scale response seems to be innate and fairly nonspecific.
