    Notes: Abstract. The water contents of a restored and an undisturbed soil were monitored over two ‘dry’ growing seasons in order to examine the differences in crop water availability from different horizons. Bulk density was approximately 10% greater in the topsoil of restored land than in undisturbed land, and the water holding capacity was less, probably because there was less organic matter. In the subsoil a major problem was the inability of the soil to allow winter rainfall to recharge the water reserves. Bulk density and penetration resistance were greater in the restored subsoil than in the undisturbed subsoil. Increases in penetration resistance on drying may have restricted rooting activity, especially in the restored subsoil.Ripping of the subsoil to a depth greater than the usual 0.5 m, possibly early in the year in a grass crop to allow new root growth to exploit the cracks, may increase water availability for future dry seasons.

    The influence of soil factors on the growth of a grass/clover sward on a restored opencast site in Northumberland, UK (1994)

    Notes: The growth of grass and clover components in mixed swards on a site restored after opencast coal mining and an undisturbed control site were compared. Soil nitrogen supply was reduced at the restored site. This inhibited grass growth but was beneficial for the clover component.Growth at the restored site was also inhibited by a compacted subsoil, which reduced available soil water content and impeded access to available soil water. This inhibited crop production from the middle of the second silage crop onwards. In 1989 this was associated with the soil at the restored site reaching permanent wilting point at 40cm. In 1990 this effect was associated with the restored site soil reaching permanent wilting point at 70cm. These drought effects reduced clover growing point population and stolon mass. Grass tiller populations were unaffected.

    Improved stability of thin cobalt disilicide films using BF2 implantation (1992)
    Woodbury, NY : American Institute of Physics (AIP)

    Notes: The thermal stability of ∼50 nm CoSi2 and TiSi2 thin films after BF2+ implantation was investigated. The electrical characteristics of silicide films were evaluated after high temperature annealing as a function of implanted BF2+ energy. It was observed that implantation with a projected range near the silicide/silicon interface produced the most stable films. The silicide/silicon interface morphology was investigated using scanning tunneling microscopy, where with appropriate BF2 implantation conditions, smoother interfaces were seen after high temperature annealing. The stabilizing effect is attributed to fluorine segregation into the silicide grain boundaries and at the silicide/silicon interface.

    Notes: [Auszug] THE accompanying photograph (Fig. 1) represents the side of a steel bar. The bar was first marked by a punch in the way shown, and the punch marks were afterwards completely filed out. The side was then polished and the bar pulled in a testing machine beyond the elastic limit of the material. ...

    Carcinoma of the gallbladder in ulcerative colitis and primary sclerosing cholangitis (1991)

    Notes: Abstract The authors present the cases of two patients with carcinoma of the gallbladder complicating chronic ulcerative colitis. Both patients had concomitant primary sclerosing cholangitis. Twelve such cases of gallbladder carcinoma have been reported in the literature. The presence of primary sclerosing cholangitis in patients with ulcerative colitis is associated with malignancy of the extrahepatic biliary tree. It is suggested that, if colectomy is necessary, the liver should be biopsied and a cholecystectomy performed if the gallbladder is deemed abnormal.

    Notes: Abstract The feeding behavior of different populations of the grasshopper,Schistocerca shoshone, was investigated in the southwestern United States. Insects from three riparian populations, with a broad spectrum of plants available to them, tended to eat plants roughly in relation to their availability except that broad-leaved herbaceous plants were avoided. Insects from a desert population in a plantation ofSimmondsia fed exclusively on that plant, as did those from another population in the Tucson mountains, despite the availability of a range of other plants. Insects from a third desert population, near Portal, fed mainly onProsopis, the dominant woody plant. In detailed behavioral experiments in the laboratory, insects from Tucson mountains readily acceptedSimmondsia, and less readily acceptedProsopis. Three other common woody plants from the habitat were generally rejected without feeding. Insects from Portal acceptedProsopis andSimmondsia with approximately equal readiness. Breeding experiments suggested that the differences between the plantation insects and those from Portal was genetic and not induced by experience. The insects from both populations were potentially polyphagous and ate a wide range of plants in the laboratory if given no alternative.

    Effects of fluvalinate on two-spotted spider mite dispersal, fecundity and feeding (1994)

    Topics: Biology
    Notes: Abstract Residual deposits of fluvalinate caused two-spotted spider mite,Tetranychus urticae Koch, dispersal by running off (run-off) and spinning down (spin-down) from treated leaves. Run-off occured at concentrations from 0.0005 g a.i. 1−1 and reached a peak at 0.01 g a.i. 1−1. Spin-down was more predominant at concentrations above 0.01 g a.i. 1−1. Spin-down and run-off proportions varied with fluvalinate formulation. Oviposition was temporarily suppressed on fluvalinate-treated leaves, presumably because of an irritant effect which reduced feeding. An emulsifiable concentrate formulation caused the largest reductions in oviposition. Oviposition returned to the level exhibited by untreated mites two days after removal from treated surfaces. Oviposition and feeding were positively correlated and both declined reciprocally with increasing fluvalinate concentration.

    Notes: Abstract The behavioral responses of final-instar nymphs of Schistocerca americanato a variety of acceptable and unacceptable plants were recorded. Palpation occurred on all plants and the palps are involved in both acceptance and rejection. On most unacceptable plants, rejection was at first dependent on biting the leaf, but subsequently on Lantana, Machaeranthera, Moms,and Physalis,rejection often occurred after palpation of the surface alone. This is consistent with the suggestion that associative learning occurs. This response did not wane even when the insects had been without food for over 2 h. There was also some evidence of an innate response to the surface characteristics of Physalis.The features of the surfaces that produced these responses were not determined.
