Leonard ColebrookDied 29 Sep 1967 at age 84 (born 2 Mar 1883).English pharmacologist and medical researcher who found an effective treatment for puerperal (childbed) fever and improved the treatment of burns. Puerperal fever resulting from infection after childbirth or abortion had affected women for centuries with severe abdominal pain, or even death. Coleman read of Domagk’s successful use of Protonsil, the first sulfonamide drug, against streptococcal infection in tests on mice and a few human subjects. In 1936, Coleman published the results of his clinical trial of Protonsil curing streptococcal puerperal fever, and launched a new era of antimicrobial chemotherapy. During WW II, he supervised the use of sulphonomides in the military. He then investigated control of infection in burns.« |
MAGIC SQUARE: Calculate A*B+C
The aim is to place the some numbers from the list (2, 3, 4, 25, 26, 27, 42, 43, 44) into the empty squares and squares marked with A, B an C. Sum of each row and column should be equal. All the numbers of the magic square must be different. Find values for A, B, and C. Solution is A*B+C.
