The Thermal Evolution of the Postshock Layer
We re-examine the thermal evolution of the postshock layer in primordial gas clouds. Comparing the time scales, we nd that the evolutionary paths of postshock regions in primordial gas clouds are basically understood by the diagram drawn on ionization degree v.s. temperature plane. The results obtained from the diagram are independent of the density, in case we do not include photodissociation ...
متن کاملThe Thermal Evolution of the Postshock Layer in Pregalactic Clouds
We re-examine the thermal evolution of the postshock layer in primordial gas clouds. Comparing the time scales, we find that the evolutionary paths of postshock regions in primordial gas clouds can be basically understood in terms of the diagram drawn in the ionization degree vs temperature plane. The results obtained from the diagram are independent of the density in the case that we do not in...
متن کاملVestigial respiratory burst activity in wound macrophages.
Macrophages from experimental wounds in rats were tested for their capacity to generate reactive oxygen intermediates. Measurements of superoxide and H2O2release, [Formula: see text]-dependent lucigenin chemiluminescence, oxygen consumption, hexose monophosphate shunt flux, and NADPH oxidase activity in cell lysates indicated, at best, the presence of a vestigial respiratory burst response in t...
متن کاملOlivary subthreshold oscillations and burst activity revisited
The inferior olive (IO) forms one of the major gateways for information that travels to the cerebellar cortex. Olivary neurons process sensory and motor signals that are subsequently relayed to Purkinje cells. The intrinsic subthreshold membrane potential oscillations of the olivary neurons are thought to be important for gating this flow of information. In vitro studies have revealed that the ...
متن کاملBurst activity of the buccal ganglion of Aplysia depilans.
1. Certain nonlinear properties of molluscan neurones suggest that network activity could be described in relation to nonlinear relaxation oscillators. 2. A specific example is fitted by the Van der Pol equation with an exponentially decaying damping coefficient, and changes in the associated energy and sensitivity are considered. 3. More precise details of the interaction pattern determined by...
