Cause of death in Plague.?Death may occur in plague either from syncope or asphyxia. In any case of plague, but especially in the pneumonic forms, there is a tendency for the respiration rate to be increased out of proportion to the pulse and temperature. I frequently noted that when the pulse and temperature rose just before death, the respiration rate rapidly fell and vice versa. I append a f...

introduction:  the aim of this in-vitro study was the evaluation of mperature changes due to irradiation of two different lasers used for the reduction of dentinal hypersensitivity and their effect on the pulp damage. the study was done for two dentin thicknesses.  methods:  twenty intact extracted third molars were prepared by longitudinal ground sectioning for 1 and 2 mm dentin thicknesses wh...

An inverted pulse tube in which gravity-driven convection is suppressed by acoustic oscillations is analogous to an inverted pendulum that is stabilized by high-frequency vibration of its pivot point. Gravity acts on the gas density gradient arising from the end-to-end temperature gradient in the pulse tube, exerting a force proportional to that density gradient, tending to cause convection whe...

Shorter pulse durations help confine thermal damage during retinal photocoagulation, decrease treatment time and minimize pain. However, safe therapeutic window (the ratio of threshold powers for rupture and mild coagulation) decreases with shorter exposures. A ring-shaped beam enables safer photocoagulation than conventional beams by reducing the maximum temperature in the center of the spot. ...

Introduction: Intensive care unit is one of stressful wards for patients and stress creates some alterations in physiologic indicators of patients. So it is necessary to use a low expense and comforting method to stabilize physiologic indicators. The purpose of the present research is to determine the effect of foot massage on physiologic indicators including pulse, respiration, mean arterial p...

In some magnetically confined plasmas, an applied pulse of rapid edge cooling can trigger either a positive or negative excursion in the core electron temperature from its steady state value. We present a new model which captures the time evolution of the transient, non-diffusive local dynamics in the core plasma. We show quantitative agreement between this model and recent spatially localized ...
