As the foodstuffs are placed in the containers before sterilization, they are cold and may be handled quickly and easily. Then the sterilization period is frequently short. This is time-saving. Finally, no rich preservatives, such as thick syrups or heavily spiced solutions, are required. Fruits may be put up in thin syrups.
The growing belief that crime comes largely from the subnormal has created a more or less definite demand for the isolation of the moron before the commission of crime and for the sterilization of certain misfits, especially after conviction.
A check is kept on the efficiency of the filtration and sterilization by mobile field laboratories. Standing orders forbid the use of unboiled milk in the army as well as fresh uncooked vegetables, so that there is little danger from these sources. When ones sees the peasants watering their vegetables with sewage, the reason for such regulations are apparent.
The remedy in greenhouse culture is thorough soil sterilization. In the open field this is impracticable and recourse must be had to a rotation with immune crops, which will starve out the root-knot. It must now be borne in mind that the root-knot worm can attack cotton, cowpea, okra, melons and a very large number of other plants.
But there can be sterilization. To begin with metals, uranium melts at 1150° centigrade, and tungsten at 3370° and iridium at 2350°. You could load such things and melt them down in space and then tow them home. And you can actually sterilize a lot of other useful materials!" The suave voice said infuriatedly; "I'll report this! You'll suffer for this!" Calhoun said pleasantly;
I have a message for you. Dara is ready to pay for every ounce of grain and for the ships it was stored in. They'll pay in heavy metals irridium, uranium, that sort of thing." The suave voice fairly curdled. "As if we'd allow anything that was ever on Dara to touch ground here!" "Ah! But there can be sterilization.
Segregation carried out for one or two generations would give us only partial control of the problem. Moreover, when we realize that each feeble-minded person is a potential source of an endless progeny of defect, we prefer the policy of immediate sterilization, of making sure that parenthood is absolutely prohibited to the feeble-minded. This, I say, is an emergency measure.
Those who intend to enter a hospital, therefore, may disregard the list of articles necessary for confinement. Similarly, the sterilization, the preparations of the room and of the bed, and personal preparations will be of interest only to the patient who intends to stay at home.
It is but a short step from antiseptic operations to our own era of aseptic surgery, and that a step in the direction of simplicity. Now we know that the sterilization of the air is rarely necessary and have dispensed with Lister's elaborate apparatus.
Full sterilization of milk for infant feeding has therefore practically been abandoned. It has been found that milk heated to 167° F. for twenty minutes, and promptly chilled by placing on ice, remains practically sterile for twenty-four hours, and it is spared the injurious changes which take place at a higher temperature. This process is known as Pasteurization.
