ISSN: 1476-4687Source: Nature Archives 1869 - 2009Topics: BiologyChemistry and PharmacologyMedicineNatural Sciences in GeneralPhysicsNotes: [Auszug] Experimental observations on the behaviour of titanium dioxide often conflict with conclusions drawn from this simple picture. Conductivity measurements indicate that oxygen diffusion through rutile is insignificant at room temperature3. This is borne out by the comparative failure of the ...Type of Medium: Electronic ResourceURL: -

This was first observed in Nature on a dry rock surface which had recently been left by the receding tide.

ISSN: 1476-4687Source: Nature Archives 1869 - 2009Topics: BiologyChemistry and PharmacologyMedicineNatural Sciences in GeneralPhysicsNotes: [Auszug] A cloud of air-dispersed rutile titanium dioxide pigment was formed by passing air from a high-pressure jet through a flask containing the dry pigment. The degree of dispersion in this cloud was assessed by collecting a specimen on a 'Formvar'-coated electron microscope specimen grid (Fig. 1). To ...Type of Medium: Electronic ResourceURL: -

ISSN: 1573-5192Source: Springer Online Journal Archives 1860-2000Topics: BiologyMedicineNotes: Summary Cylicospirura (Cylicospirura) advena n.sp. described from specimens obtained from a feral cat in New Zealand is characterized by the presence of toothless rounded knobs on the anterior ends of the longitudinal supporting ribs in the buccal capsule; a vulva either anterior or posterior to the oesophago-intestinal junction; its small size (less than 6 mm) and the presence of a thin, disc-like process on the tip of the short spicule. Additional figures are provided of Cyathospirura dasyuridis Mawson, 1968, and the presence of conspicuous lateral alae of Cylicospirura (C.) heydoni (Baylis, 1927) is noted for the first time. ac]19810222Type of Medium: Electronic ResourceURL: -

The increase can be explained as the sum of a direct steroid effect, independent of protein synthesis, and an indirect effect, dependent on proteins synthesized after an increase in the hormone titer. By contrast, the peaks of DDC activity in embryos, and perhaps in the first two larval instars and in imaginal discs as well, cannot be ascribed to any direct steroid effects. In fact, a decreasing hormone titer might be required before the Ddc gene can be expressed at these stages. The stage-specific differences in the molecular mechanisms regulating Ddc gene activity may be reflected in the phenotype of an activity variant, Ddc+4. Molecular studies now underway on the variant Ddc gene might help us to understand the complex multifunctional region that we believe lies upstream of the gene and regulates its expression during development.Additional Material: 3 Ill.Type of Medium: Electronic ResourceURL:
