Critical time in the PWC 170 test: the influences of work load duration, work load intensity, and state of training

Robin Victor Carr
The purpose of this study was to examine the concept of "critical time" (i.e. the time required to achieve steady-state heart rates) in the administration of the PWG 170 three-stage submaximal bicycle ergometer test. Specifically, the problem involved determining the effects of four different work load duration protocols on 'D' scores (which reflected the relative attainment of steady-state heart rates) and on PWG 170 scores. The combined effect of the order and relative intensity of...

Control of apnea in the hibernating ground squirrel

Rhonda J. Garland
During hibernation the breathing pattern of the golden-mantled ground squirrel consists of short episodes of breathing separated by pauses ranging in length from less than a minute to greater than 30 minutes. A breathing pattern as such results in wide fluctuations in the partial pres sure of oxygen (PO₂ )and carbon dioxide (PCO₂)in the blood and lungs; the increase in PO₂ and decrease in PCO₂ during a breathing episode are reversed in the following apnea....

Imaginative space and the construction of community : the drama of Augustine’s two cities in the English Renaissance

Gretchen E. Minton
This thesis traces the development of Augustine's paradigm of the two cities (the City of God and the earthly city) in the cultural poetics of the English Renaissance. Although scholars have studied the impact of Augustine's model on theology, historical consciousness, and political theories in the Middle Ages and Renaissance, little attention has been paid to the genealogy of the more specifically "literary" aspects of the idea of the two cities. My line of inquiry...
