The Fontana history of chemistry
policy; tension between national and local interests; the importance of communications; and the financial impact of the epidemic are prominent themes in all. Each of these books does, however, make a distinct contribution to our understanding of yellow fever and its impact on the late nineteenth-century South. Thus Humphreys places the epidemic within the broad context of local and national pub...
متن کاملWalter Fontana – Research
The formal structure of evolutionary theory is based upon the dynamics of (populations of) “individuals.” It therefore assumes the entities whose existence it is supposed to explain.

Ten years ago I could have subscribed one of the thesis of this paper: “Enculturated great apes might transform the typically astute primate behavior-reading in...
متن کاملThe Fontana paradoxical reflex?
This commentary describes the "deflation cough" caused by deep lung deflations. Deflation cough is a paradoxical reflex similar to that described by Henry Head in 1889 for lung inflations that probably is mediated by the same sensors and afferent fibers in the lungs and activated by gastroesophageal reflux. We discuss how this reflex must be self-limiting, the general role of paradoxical reflex...
متن کامل2 Josep Àlvarez Montaner and Gennady Lyubeznik
LetR = k[x1, . . . , xd] be the polynomial ring in d independent variables, where k is a field of characteristic p > 0. Let DR be the ring of k-linear differential operators of R and let f be a polynomial in R. In this work we prove that the localization R[ 1 f ] obtained from R by inverting f is generated as a DR-module by 1 f . This is an amazing fact considering that the corresponding charac...
