Logan, Gabriella Berti. ” American Historical Review 99 (June 1994): 785–812. Bechtereva, Natalia Petrovna Mozans, H. J. Woman in Science. : MIT Press, 1974, 203–210. F Bechtereva, Natalia Petrovna (1924– ) Russian brain researcher Natalia Bechtereva developed techniques to study electrical signals from the brain in action, providing information about the way nerve cells work when people think.
Eventually, Belcher believes, nanoscale components made by biological processes will be used in computer parts far tinier than those manufactured today. Such components could make computers and similar devices faster and more powerful as well as smaller than today’s models. Biologically created nanomaterials may also be useful in sensors for medicine and the military, devices that deliver drugs to particular cells, and ways to store medically valuable substances such as vaccines. “We found by accident that our viruses are really, really stable when stored as solid ﬁlms,” Belcher explained during a speech in Australia in 2003.
Ayrton’s health began to fail in 1901, and he and Hertha moved to the coast in an attempt to improve it. ” To learn how waves shaped the sand, she built glass tanks in her attic, put a layer of sand in the bottom, and ﬁlled them with water. She put the tanks on rollers to imitate wave motion. She found that when waves moved constantly back and forth over the same spot, they created regular ripples that eventually pushed the sand into two mounds between the crests of the waves. Ayrton believed that this kind of wave action formed both sand dunes on the shore and underwater sandbanks that often wrecked ships.
