...used so far in 70 cases by Dr. Dotter in Portland and in 30 by Dr. Gensini in Syracuse, the procedure begins with insertion of a thick, hollow needle (under local anesthetic) into the femoral artery. Through the needle the diagnostician passes a flexible steel spring, like a plumber's snake (or like the bass strings of pianos and guitars). The needle is soon withdrawn. Inside the steel spring is a single-strand steel wire for stiffening. As in the Syracuse housewife's case, polyethylene tubing is slipped over the steel spring. But in her case, the doctors...
...truck, jalopy and a variety of barely airworthy small planes, visited scores of river towns, oil and mineral exploration camps, pioneer farms, mines, missionary stations and Indian villages deep in the jungle. Once, to photograph a tribe of Mato Grosso Indians, De Carvalho and Linck hiked nine miles through thick jungle and at dusk hiked out again, preceded by a native guide armed with a flashlight and rifle. At the camp of a seismographic crew, they just missed a battle in which seven Indians were killed during a surprise attack on a geologist...
This peculiar behavior is explained by the structure of graphite crystals, whose carbon atoms are arranged in sheets one atom thick. When the sheets are stacked up in a crystal, the distance between the atoms in adjoining layers is more than twice as great (3.35 angstroms*) as the distance between the atoms in the individual sheets (1.42 angstroms). In ordinary commercial graphite, microscopic crystals are jumbled almost at random, but in Pyrographite they are mostly aligned with their sheets parallel (see diagram). This builds up a layered structure that resists the motion of heat across the layers but permits easy...
Pyrographite can be deposited in sheets up to ½ in-thick, can be shaped to form rocket nozzles and caps for nose cones. Both these parts get punishing heat concentrated on rather small areas. The beauty of Pyrographite is that it conducts heat away from these danger points as fast as copper can, but it does not permit nearly as much heat to pass through it. A Pyrographite nose cone, for instance, spreads the heat of air friction over a large area and permits it to be radiated harmlessly away, but it does not let heat strike through the cone...
...irrepressible capitalist ("The Rolls is the only sports car I will drive in a Russian blizzard"), shows dangerous bourgeois-individualistic tendencies by riding her tricycle on the frozen Baltic, and utters subversive observations ("Everybody watches everybody in Moscow"). But she makes up for it by getting right into the thick of cultural exchange, playing chopsticks in F at Tchaikovsky Hall, and doing a "rawther unusual" ballet with three elderly snow sweepers, which cries out for Choreographer Jerome Robbins. The book's most remarkable character is Eloise's guide, Zhenka, who has a magnificently declarative style: "Is possible...
