Constancy of the Internal Environment
Claude Bernard (1813-1878) was the founder of modern experimental physiology and one of the most famous French scientists of all time. Although he is particularly remembered today for his concept of the constancy of the internal environment, this idea had no impact in his lifetime. This article considers his achievements and some possible reasons for the delay in understanding his ideas about t...
متن کاملInterplanetary Radiation and Internal Charging Environment Models for Solar Sails
A Solar Sail Radiation Environment (SSRE) model has been developed for defining charged particle environments over an energy range from 0.01 keV to 1 MeV for hydrogen ions, helium ions, and electrons. The SSRE model provides the free field charged particle environment required for characterizing energy deposition per unit mass, charge deposition, and dose rate dependent conductivity processes r...
متن کاملLogical Structure of Environment and Its Internal Representation
It is for the cultural anthropologists to explain the great popularity of a recent publication1 that bases man’s evolutionary success on his alleged intrinsic habit to kill and to destroy. Since this belief is contrary to the thesis on which my paper today rests, I hope you will forgive me if I open my remarks with an apparently unpopular confession: in contrast to the tenets of some self-appoi...
متن کاملBio-Environment-Induced Degradation and Failure of Internal Fixation Implants.
Internal fixations provide fast healing but their failure remains problematic to patients. Here, we report an experimental study in failure of three typical cases of metals: a bent intramedullary stainless steel nail, a broken exterior pure Ti plate, and a broken intramedullary stainless steel nail. Characterization of the bent nail indicates that those metals are vulnerable to corrosion with t...
متن کاملClaude Bernard and the Internal Environment: A Memorial Symposium
In 1859 Darwin's The Origin of'Species appeared in print, followed six years later by Claude Bernard's Introduction a l'etude de la medecine experimentale. Bernard and others described The Origin as the end of classical natural history-yet each man sired distinct philosophical lineages of twentieth century biologic science. Bernard is the father of modern, non-Darwinian, deductive rationalism, ...
