ONE-DISH MEAL CASSEROLE
1 lb. hamburger
1 tbsp, butter
2 c. sliced raw potatoes
1/2 c. chopped onion
1 c. sliced carrots
1/2 c. uncooked rice
1/4 c. chopped green pepper (opt.)
2 c. tomatoes
1/2 tsp. salt
1/4 tsp. pepper
1 c. hot water

Brown hamburger in butter. Place a layer of meat in 2-quart casserole. Top with a layer of each vegetable and rice. Sprinkle with salt and pepper. Pour hot water over all. Cover. Bake at 325 degrees for 2 hours. Add more water if needed. Yield: 6-8 servings.

Absorption of Gases. - In physics, the property which all liquids possess in greater or less degree of taking a certain quantity of gas into chemical combination with themselves. Heat is given off during this process of absorption, and, should it afterwards be desired to separate the gases, an equivalent amount of heat to that given off, must be applied to the liquid. This principle is the foundation of the ammonia absorption process of refrigeration as water at 32° F. can absorb over one thousand times its volume of ammonia gas.

MISSOURI HASH
2 Large  onions, sliced
2 green peppers, chopped
3 tbsp. shortening
1 lb. hamburger
2 c. canned tomatoes, mashed 1/2 c. rice
1 tsp. chili powder
1 tsp. salt
1/4 tsp. pepper

Cook onions and green peppers slowly in shortening until onions are yellow. Add hamburger; saute until mixture falls apart. Add tomatoes, rice and seasonings. Arrange in large casserole; cover. Bake at 375 degrees for 45 minutes or until done. Yield: 8 servings.

The digestive system may be conceived in its simplest form as a muscular tube into which glands all along its course pour secretions. Some of these glands are embedded in the wall of the tube ; some, such as the pancreas and the liver, are so large that they lie outside and discharge their secretion through a duct which empties into the digestive canal. The muscular action of the walls of the canal pushes the food ever onward.

Absorb. - To drink in, or suck up, as a sponge absorbs water.

Absorber.  -  In nuclear engineering, a sheet or other body of material placed between a source of radiation and a detector such as: (1) determining the nature or the energy of the radiation: (2) reducing the intensity of the radiation at the detector, as in shielding: or (3) giving the radiation some desired characteristic, as by preferential transmission of one component of the radiation. Such an absorber may function through a combination of processes of true absorption, scattering and slowing down. In a nuclear reactor, a substance absorbs neutrons without reproducing them. Such a substance may be useful in control of a reactor, or if unavoidably present, may produce an undesired impairment in neutron economy. Neutron absorption is an important function of the shield surrounding a reactor.

Uranium is not the only material used for making A-bombs. Another material is the element plutonium, in its isotope Pu-239. Plutonium is not found naturally (except in minute traces) and is always made from uranium. This can be done by putting U-238 in a nuclear reactor. After a while, the intense radioactivity causes it to pick up the extra particles, so that more and more of its atoms turn into plutonium.

Plutonium will not start a fast chain reaction by itself, but this difficulty is overcome by having a neutron source, a highly radioactive material that gives off neutrons faster than the plutonium itself.
