...first time. Early in 1941, while she was in a Rumanian prison, Prime Minister Antonescu had the idea of exchanging Ana for a leader of the Peasant Party, Ion Codreanu, held by the Russians. The Russians wanted a package deal: they would trade Codreanu for Ana and another Rumanian Communist named Gheorghiu-Dej. When Antonescu insisted on a one-for-one trade, the Russians were quite ready to let Ana rot in jail, and asked only for Gheorghiu-Dej. Instead wily Antonescu gave them Ana. While Gheorghiu-Dej sweated out the war in a concentration camp, Ana squeezed herself into...

But gradually the mountains of South America, where the chinchilla lived, were swept almost clean, and the fur fell from fash ion. In 1923, an Anaconda mining engineer named Mathias Chapman captured eleven of the remaining wild chinchillas, brought them from the Andes to Southern California in an ice-cooled crate. He started breeding them and founded the domestic chinchilla industry. From his original eleven animals sprang virtually all the estimated...
Certain salts and minerals are removed from the water as it is passed through the membranes by a chemical process known as "ion exchange," which separates the various impurities according to the electrical charges they carry...
Through a non-wettable plastic tube, which avoids damage to delicate formed elements, heretofore caused by collecting with glass or rubber tubing, the blood flows into a column of resinous beads (called an ion exchange column). Here calcium is removed to prevent clotting. On this resin are collected platelets, tiny disk-like formed elements of the blood which initiate the clotting process, obtained in this machinery for the first time in substantial yield...
...components not precipitated by the zinc salts form a Stable Plasma Protein Solution which passes through a second ion exchange column to remove the sine. This solution has been successfully injected into soldiers and civilians during and after World...
