    Description / Table of Contents: The transition in the mode of heat transfer from conduction to convection in a layer of water formed continuously by melting ice from below has been determined experimentally. This was accomplished by locating the inflection point on the curve relating the water-ice interface (or melting front) and time. Thus, the critical Rayleigh number, Rac, at which convective heat transfer started can be correlated empirically as a function of warm plate temperature, Ts, by Rac= 14,200 exp(-6.64 x 10^-2 Ts). This relation is valid for Ts varying from 7.72 to 25.50°C. The initial ice temperature T0 was varied from -4.8 to -22.00°C. The effect of T0 was found to be insignificant. Homogeneous, bubble-free ice was prepared and used in all the experiments.

    Description / Table of Contents: The flow of a compressible fluid through a deep layer of a porous medium with non-uniform permeability was analyzed. The volumetric behavior of the fluid was described first by the perfect gas law, then by the van der Waal's equation of state. Darcy's law was assumed to be valid. For illustration, the model of air flowing through a deep bed of naturally compacted snow was used to carry out numerical computation. The permeability of snow was considered as a function of depth. The nonlinear partial differential equation obtained by combining the continuity equation with Darcy's law was solved by finite difference technique. A time dependent exponential decay boundary condition was used which included the step-rise constant boundary condition as a limiting case. Pressure distributions in the porous medium calculated from the assumption of ideal gas and van der Waal's gas were compared. The data were presented in dimensionless variables.

    Topics: Biology , Medicine
    Notes: Abstract The influence of cisplatin, an anticancer agent, on DNA synthesis and cell cycle progression of a cisplatin-resistant cell line was investigated. Cell cycle analysis using flow cytometry showed that cytotoxic concentrations of cisplatin caused a transient inhibition of parental HeLa cells at S phase, followed by accumulation at G2 phase. In contrast, the resistant cells progressed through the cell cycle without being affected by the same treatment. However, cell cycle distributions were the same in the resistant and the parental cells at IC50, the drug concentration inhibiting cell growth by 50%. Studies using a [3H]thymidine incorporation technique also demonstrated a transient inhibition of DNA synthesis in HeLa cells by cisplatin; such inhibition was greatly reduced in the resistant cells. These data argue for the hypothesis that the inhibition of DNA synthesis is important in determining cisplatin-induced cytotoxicity. In addition, the accumulation of cells at G0/G1 by serum starvation was not effective in the resistant cells compared to the parental cells, suggesting that the control of cell cycle exiting is also altered in the resistant cells. Taken together, these results support the notion that alterations in cell cycle control, in particular G2 arrest, are important in determining the sensitivity or resistance of mammalian cells to cisplatin and may have a role in clinical protocols.

    Keywords: Nitrification ; Tropical soil ; Subtropical soil ; Nitrifying population
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Geosciences , Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Nitrification was measured in five different soils (slate alluvial soil, sandstone shale alluvial soil, sandstone shale and slate alluvial soil, red soil, and Taiwan clay). In these soils different lag periods were recorded before the onset of nitrification. Nitrifying activity was highest in sandstone shale alluvial soil and the lowest in acidic red soil. A part from those in the red soil, the numbers of nitrifying bacteria detected were all higher than numbers reported in temperate soils. However, there were no clear relationships between the numbers of nitrifying bacteria and the rate of nitrification in these soils. When soil cores were incubated for 3 weeks, no NO inf2 sup- or NO inf3 sup- was defected in the slate alluvial soil. This was ascribed to denitrification.
