Performing the Chemical Test by Reagent Strip The urine must be collected using appropriate technique and be tested within one hour ofcollection. If tests cannot be performed within this time, the specimen may be refrigerated for upto 8 hours.
Elastic and Inelastic Collisions. A perfectly elastic collision is defined as one in which there is no loss of kinetic energy in the collision. An inelastic collision is one in which part of the kinetic energy is changed to some other form of energy in the collision. Any macroscopic collision between objects will convert some of the kinetic energy into internal energy and other forms of energy, so no large scale impacts are perfectly elastic.
In most cases of bimalleolar fracture, the lateral malleolus and the medial malleolus are broken and the ankle is not stable. A bimalleolar equivalent fracture means that in addition to one of the malleoli being fractured, the ligaments on the inside (medial) side of the ankle are injured.
