The low-temperature relaxation dynamics of supercooled liquids are a long-standing theoretical problem of considerable interest. The vast amount of experimental data on such liquids indicates that viscosity and diffusion in supercooled liquids are non-Arrhenius over a wide range of temperatures. The non-Arrhenius temperature dependence of the relaxation time of the slow modes in glass-forming liquids is investigated in connection with the topology of the potential energy landscape in configuration space. An analogy is made between the derived dynamical equations and Cooper's formulation of the pair equation in superconductivity. 相似文献

Methane production in unamended and rice-straw-amended soil at different moisture levels 总被引:3,自引:0,他引:3

CH4 production in an alluvial soil, unamended or amended with rice straw (1% w/w), was examined under nonflooded [–1.5 MPa, –0.01
MPa and 0 MPa (saturated) and flooded (1 : 1.25 soil to water ratio)] conditions during a 40-day incubation in closed Vacutainer
tubes. CH4 production was negligible at –1.5 MPa, but increased with an increase in the moisture level. Addition of rice straw distinctly
increased CH4 production in the soil at all moisture levels including –1.5 MPa. Evidence, in terms of the drop in redox potential and Fe2+ accumulated, suggested that the addition of rice straw hastened the reduction of the soil, even under nonflooded conditions;
thus its addition stimulated even the nonflooded soil to produce CH4 in substantial amounts. Our results indicate that many currently unidentified sources of CH4, possibly including organic-amended nonflooded soils, may make a significant contribution to the global CH4 budget.

The Genus Edwardsiella comprises of bacteria differing strongly in their biochemical characteristics, physiological features, natural habitat and pathogenic properties. The most common species of the genus is Edwardsiella tarda, recovered from a variety of environmental and animal sources. In this study 51 isolates including one reference strain obtained from freshwater culture systems were analyzed for their genomic diversity by BOX-PCR and PCR-ribotyping. By comparison of fingerprint of different isolates 27 and 32 genotypes were obtained by PCR-ribotyping and BOX-PCR respectively. Cluster analysis of genetic profile obtained by BOX-PCR and ribotyping clearly showed 9 and 8 clusters respectively. Some correlation between BOX-PCR and ribotyping was observed. Several clusters delineated on the basis of source of isolation in the dendrogram by BOX-PCR with 70% cut off value had corresponding clusters in the ribotyping with 50% cut off value. Some of the genotypes were found to be habitat specific. However, there was mixing and dispersal of most of the genotypes obtained from water, sediment and fish samples. Of both the techniques, BOX-PCR was found to be more discriminating than ribotyping. 相似文献

Canine venereal tumor cells were grown in monolayer and tumor tissue fragments were maintained in vitro for 56 days in medium-199. Attachment and cell replication were evident within 17 hours and monolayer was obtained by the tenth day. Growth at first comprised mainly round cells with abundance of cytoplasm and vesicular nuclei, and a few spindle-shaped cells. Later cells became more elongated and like fibroblasts. Cell degeneration started by the 17th day and most were degenerated by the 24th day. Necrosis and depletion of cell population were prominent in tumor explants during the first 2 weeks. Distinct cell multiplication was evident by the 21st day and tumor fragments were repopulated with cells resembling the original tumor by the 56th day. Two distinct morphological cell types were seen: small cells with vesicular, round to oval nuclei and acidophilic cytoplasm; and the large cells with large hyperchromatic nuclei and acidophilic cytoplasm. 相似文献

Intracellular antigens of strain DN-599 bovine herpesvirus were detected in the cytoplasm and the nucleus of infected bovine embryonic kidney cells by the indirect immunoferritin (IF) technique. Specific tagging was observed in viral envelope and capsids. Aggregates of viral particles heavily coated with antibody were seen by immune electron microscopy (IEM). 相似文献
