Growth and development responses to UV-B exclusion in crops

UV-B radiation affects crop plants. Growing interest has been shown in studying the effectsof UV-B radiation exclusion on crops since 1993. This article summarized the generalconsequences of UV-B radiation exclusion on crop plants from the aspacts of plant morphology,growth and development. UV-B exlusion has promoting effects on plant height, internodeand leaf size. UV-B exclusion increases roo...

Plant adaptation to low atmospheric pressures: potential molecular responses.

There is an increasing realization that it may be impossible to attain Earth normal atmospheric pressures in orbital, lunar, or Martian greenhouses, simply because the construction materials do not exist to meet the extraordinary constraints imposed by balancing high engineering requirements against high lift costs. This equation essentially dictates that NASA have in place the capability to gr...

fiscal pressures Uncompensated care : hospitals ' responses to Zwanziger

This DataWatch examines the impact of hospital competition, the Medicare prospective payment system (PPS), and Medi-Cal selective contracting on the provision of uncompensated care by private hospitals in California during 1980-1989. It finds that hospitals subject to more intense competition and greater f iscal pressure f rom Medicare and Medi-Cal reduced their provision of uncompensated care ...

Cardiovascular responses to various pulsatile pressures in the carotid sinus.

SCHMIDT,ROBERT M., MAMORUKUMADA,AND KIICHI SAGAWA. Curdiovascular responses to various pulsatile pressures in the carotid sinus. Am. J. Physiol. 223 (1): l-7. 1972.-To extend the knowledge of the carotid sinus reflex, we forced the isolated sinuses of anesthetized dogs with sinusoidal (pulsatile) pressures using multiple combinations of mean level, amplitude, and frequency of pulsation. The ref...
