SULFUR DIOXIDE INJECTION INTO LAYER PARTIALLY SATURATED WITH WATER

Sulfur dioxide: episodic injection shows evidence for active venus volcanism.

Pioneer Venus ultraviolet spectra from the first 5 years of operation show a decline (by more than a factor of 10) in sulfur dioxide abundance at the cloud tops and in the amount of submicron haze above the clouds. At the time of the Pioneer Venus encounter, the values for both parameters greatly exceeded earlier upper limits. However, Venus had a similar appearance in the late 1950's, implying...

Self-similar dynamics of liquid injected into partially saturated aquifers

The injection of liquid from a central well into a partially saturated aquifer of finite thickness is described using similarity solutions. The solutions illustrate that injection leads to a growing zone around the source in which the fluid fills the whole depth of the aquifer. Beyond this zone, the current adjusts to the depth in the far field as the fluid slumps under gravity. The radial exte...

Numerical Analysis of Infiltration into Partially Saturated Soil Slopes

Sulfur Dioxide

The ubiquity of sulfur dioxide as an air pollutant combined with reports of effects of the gas and its blood metabolite on DNA and chromosomes, prompted a study of possible mutagen action on mammalian oocytes. Utilizing in vitro and in vivo systems, mouse, ewe, and cow oocytes were examined for cytologic evidence of structural or numerical damage in meiosis. Fragmentation with rearrangement see...

The Deoxygenation Kinetics of Hemoglobin Partially Saturated with Carbon Monoxide

The deoxygenation rate of hemoglobin solutions partially saturated with carbon monoxide, in the presence and absence of 2,3-diphosphoglycerate (2,3-DPG) at 23” and pH 7.0 and 8.0 have been measured. When the rate is calculated over the initial, 30% of the reaction, solutions containing 98% HbOa show an increase in the rate as hemoglobin deoxygenates both at neutral and alkaline pH. Partial satu...
