In the first use of these catheters in humans, each catheter was specifically shaped to match the size and shape of the aorta of the subject. His work was documented in 1967, and by 1968 the Judkins catheters were manufactured in a limited number of fixed tip shapes.
Cut of beef. Cuts of beef are first divided into primal cuts, pieces of meat initially separated from the carcass during butchering. These are basic sections from which steaks and other subdivisions are cut. The term primal cut is quite different from prime cut, used to characterize cuts considered to be of higher quality.
Exceptions, in which the meat is sliced parallel to the fibers, include the skirt steak that is cut from the plate, the flank steak that is cut from the abdominal muscles, and the Silverfinger steak that is cut from the loin and includes three rib bones. When the word steak is used without qualification, it generally refers to a beefsteak. In a larger sense, there are also fish steaks, ground meat steaks, pork steak and many more varieties of steaks. Steaks are usually grilled, but they can be pan-fried, or broiled. Steak is often grilled in an attempt to replicate the flavor of steak cooked over the glowing coals of an open fire. Steak can also be cooked in sauce, such as in steak and kidney pie, or minced and formed into patties, such as hamburgers.
