The effect of water velocity on shape has been well documented for freshwater fishes, and streamlining and robustness have been linked with improved performance in different water-velocity (high and low, respectively) conditions (Langerhans et al. 2003, Haas et al.
One of the most inspiring deaf or deafblind women is Helen Keller. Even today, her biography fascinates people. Helen Keller was born June 27, 1880 in Tuscumbia, Alabama. An unidentified illness took her hearing and sight when she was only 19 months old. After losing both, she became wild and uncontrollable due to her inability to communicate and learn.
While she was there she had an operation on her eyes which allowed her to read normally for a limited amount of time. She stayed at Perkins for six years and graduated valedictorian of her class. Anne Sullivan Macy arrived in Tuscumbia, Alabama to be Helen Kellerâs teacher on March 3, 1887. She began spelling into Helenâs hand and after about a month Helen âmade contact with realityâ. When Helen was older she went to Radcliffe College. Anne âreadâ her all the texts that were not available in Braille.
