Jean-Baptiste Charcot and Brazil.

Jean-Baptiste Charcot, a neurologist from the famous Salpêtrière school and a renowned maritime explorer, visited Brazil twice. The first visit was in 1903, when the first French Antarctic expedition, traveling aboard the ship Français, made a very short stopover in Recife, in the state of Pernambuco. The second took place in 1908, during the famous voyage of the Pourquoi Pas? to the Antarctic,...

Jean-Baptiste Bélanger: hydraulic engineer and academic

Jean-Baptiste Bélanger (1790–1874) worked as a hydraulic engineer at the beginning of his career. He developed the backwater equation to calculate the freesurface profile of gradually varied, steady open channel flow. He also introduced the concept of critical flow and the numerical technique called the direct step method. Later, as an academic staff member at the leading French engineering sch...

Jean-Baptiste Charcot, the French Antarctic expedition and scurvy.

During the second expedition to the South Pole, Commander Jean-Baptiste Charcot and some members of the crew of "Pourquoi Pas?" developed symptoms suggestive of scurvy. The clinical picture was totally reversed after dietary changes.

where subscripts 1 and 2 refer to the upstream and downstream flow conditions, respectively; F Froude number; F=V / gd; d and V flow depth and velocity, respectively; and g=gravity acceleration. The hydraulic jump is typically classified in terms of its inflow Froude number F1=V1 / gd1, which must be greater than unity Bélanger 1828; Henderson 1966 . For F1 slightly above unity, the hydraulic j...
