A Model for Service Life Control of Selected Device Systems

This paper presents a way of determining distribution of limit state exceedence time by a diagnostic parameter which determines accuracy of maintaining zero state.For calculations it was assumed that the diagnostic parameter is deviation from nominal value (zero state).Change of deviation value occurs as a result of destructive processes which occu

Progress in animal model research on obstructive sleep apnea

Obstructive sleep apnea (OSA) is a common sleep disorder, and its pathophysiological mechanism complex and not fully understood.This article elaborately explores three categories of OSA animal models: natural, direct and indirect, emphasizing their advantages and disadvantages in simulating OSA pathophysiological processes.Natural OSA models primar
