A practical method of studying the dynamics respiratory function associated with registration electrical impedance conductive biological fluids exhaled by patient is described. In model measuring cell, physical causes and relationships in conductivity air flow, saturated an electrolytic fluid aerosol created ultrasonic nebulizer have been investigated experimentally. The design a new spirometer...
ABSTRACT Introduction China is currently experiencing the problem of population aging, and health status elderly has become a major focus social attention. Objective Study effect aerobic exercise on indices physical function in elderly. Methods 40 people performed 5 times week for 8 weeks. Each lasted 60 minutes, including 10 minutes warm-up, (running, brisk walking, square dancing, among other...
BACKGROUND Abnormalities in the left atrial (LA) structure and function may develop in patients with paroxysmal atrial fibrillation (AF). We sought to determine the contribution of LA mechanical function, including LA stiffness, to AF by comparing patients with paroxysmal AF with normal control subjects, and to evaluate whether LA mechanical function and stiffness are related with the structura...
An index e in a numbering of partial-recursive functions is called minimal if every lesser index computes a different function from e. Since the 1960’s it has been known that, in any reasonable programming language, no effective procedure determines whether or not a given index is minimal. We investigate whether the task of determining minimal indices can be solved in an approximate sense. Our ...
