Listeria. can be found in a variety of foods, including soft cheeses (e.g. Brie, Camembert, Mexican-style fresh cheeses, Roquefort, Bleu), hot dogs and other ready to eat meats, smoked fish, lettuce, coleslaw, other salad items, ready-to-eat foods purchased from store. delicatessens, and raw milk.
The kinetic energy of the arrow during the launching process of a recurve bow is calculated in dark-green-box cells in Appendix C and shown as a dark green curve in Fig. B-2. The kinetic energy is compared with the static energy released by the bow, shown in a red curve in Fig. B-2.
Spine was established in modern times by Easton who uses a 29 arrow. You place this arrow on two posts measured out 28 apart. You then place a 1.94 pound weight in the middle of the shaft and measure how far the arrow shaft drops down. This gives you a static (non-moving) spine. When an arrow is launched from a bow, the arrow flexes (dynamic spine).
