Scooping up a person's lost blood and putting it back into his veins is a risky procedure. The blood may clot. Blood cells may be injured. Germs may get into the fluid. But in emergency such blood may be strained through gauze and mixed with a solution of sodium citrate. Able Surgeon Morris did this, as he had done in emergencies before. Junior Evans' blood pressure became almost normal before he left the operating table. Last week he was on the way to recovery...
...well known that the rate of heat transfer between a fluid and a metal tube through which it is flowing varies widely, depending upon the temperature of the tube, the size of the tube, the nature of the fluid, and the velocity of flow. All of those influences are to be studied in this research, and it is hoped that ultimately it will be possible to predict rates of heat transfer from values of simple properties of the fluid which can be measured with ordinary laboratory apparatus, such as density, viscosity, thermal conductivity, and the like...
...desire for correlating the experimentally determined heat transfer rates with these various properties of the fluid makes it necessary that these properties be determined for the fluids used in the test apparatus. Mr. Smith has therefore set up an apparatus originally designed by Professor Bridgman for determining thermal conductivity. An apparatus for measuring specific heats was set up last year by another graduate student. The laboratories already had apparatus for viscosity, specific gravity, and the like...
Excerpts from his legal philosophy, set down in his books and lectures: "Property, like liberty, though immune under the Constitution from destruction, is not immune from legislation essential for the common good. . . . Nothing is stable. All is fluid and changeable. ... I was much troubled in spirit in my first years on the bench to find out how trackless was the ocean on which I had embarked. I sought for certainty. I have become reconciled to the uncertainty, because I have grown to see it is inevitable...
Last week's product is even more convenient. Heretofore it has been dangerous to inject liver extracts directly into the blood stream. The extracts behaved like protein poisons. By fiddling with the liver juices after a method which has been patented, Professors Sturgis & Isaacs developed an innocuous fluid. Once introduced into a vein it whips the blood into a fury of red cell reproduction. The fury lasts for four to six weeks, when another intravenous injection becomes necessary. That is more pleasant, anemics find, than swallowing hog stomachs once a day or eating beef liver at every meal...
