Raymond Pearl, Smoking and Longevity

Benefits of smoking cessation for longevity.

OBJECTIVES This study determined the life extension obtained from stopping smoking at various ages. METHODS We estimated the relation between smoking and mortality among 877,243 respondents to the Cancer Prevention Study II. These estimates were applied to the 1990 US census population to examine the longevity benefits of smoking cessation. RESULTS Life expectancy among smokers who quit at ...

the investigation of factors influencing on postharvest longevity of tuberose cut flower cv. pearl on (polianthes tuberosecv. pearl)

the tuberose cut flower is much less longevity in postharvest. the less vase life due to stress of deficit carbohydrate and quick respiration on inflorescence. in this study, effectiveness factors, sucrose, cacl2, al2so4 and re-cut the stems. in current research two separate experiments were arranged as a factorial based on compeletly randomized design. the first experiment were added to all ex...

Processes Raymond A . Wright and

The design of controllers for nonlinear, nonminimum-phase processes is one of the most difficult control problems currently faced. Current available control algorithms for nonlinear processes rely implicitly or explicitly on an inverse of the process. Linear control methods for nonminimum-phase processes are based on a decomposition of the process into a minimum-phase and a nonminimum-phase par...
