There is no difference in the water heated by microwaves compared to water heated by another source (like a gas flame, or electric element). Microwaves are non-ionizing radiation, so do not alter the substance other than exciting it to higher temperatures.. Below is a Science fair project presented by a girl in a secondary school in Sussex. In it she took filtered water and divided it into two parts. The first part she heated to boiling in a pan on the stove, and the second part she heated to boiling in a microwave.
An avulsion fracture is an injury to the bone in a location where a tendon or ligament attaches to the bone. When an avulsion fracture occurs, the tendon or ligament pulls off a piece of the bone. Avulsion fractures can occur anywhere in the body, but they are more common in a few specific locations.
Tendon excursion takes place as the muscle contracts and the joint rotates. The amount of tendon excursion is related to the amount of the joint rotation. A pulley-type constraint keeps the tendon path close to the bone when the tendon crosses a joint.roper excursion and gliding of the tendon determine the efficiency of this function. Studies of the tendon excursion and gliding based on two simple mechanical concepts have resulted in several significant clinical implications.
