Metabolic Desynchronization in Critical Conditions: Experimental Study

Periodic desynchronization in humans under outer space conditions.

Metabolic Conditions in Chlorella

1. The effect of nitrate reduction and assimilation on the CO(2)/O(2) quotient of gas exchange has been used as an index of the relative rates of carbon and nitrogen assimilation in Chlorella pyrenoidosa. Changes in over-all metabolism induced by starvation, high light intensity, and nitrogen deficiency have been studied in comparison with the metabolism of cells growing at light-limiting inten...

Study of Processes in Critical Operating Conditions of Sliding Pairs

Preliminary note The occurrence of working irregularities in journal bearing such as loss of geometry correctness, sudden failure of lubrication, overloading, etc., requires that serious damage of journal bearings have to be overcome in a short period of time. In such cases, it is important that the applied combinations of materials and lubricants do not have a tendency to seizure. Such critica...

A Critical Study of Boundary Conditions in Device Simulation

Abstrac t In most approaches to device simulation a set of coupled paitial differential equations must be solved. The solution is mainly determined by the applied boundary conditions. This paper critically investigates the commonly used types of boundary conditions from both the mathematical and the numerical points of view. Consistency and convergence behavior are illustrated with computationa...

Hemorrhagic shock hemodynamic and metabolic behavior: experimental study in dogs.

BACKGROUND AND OBJECTIVES Different experimental models have been used to illustrate hemodynamic and metabolic changes during hemorrhagic shock. This study aimed at observing hemodynamic and metabolic behaviors during a sequential and progressive model of hemorrhagic shock in dogs to determine which indices are earlier changed. METHODS The study involved 13 dogs under total intravenous anesth...
