Ammonia is manufactured by combining nitrogen and hydrogen directly. Nitrogen and hydrogen are compressed to about 250 atmospheres and heated to about 4000 centigrade. They are then passed over an iron catalyst to form ammonia. The reaction is reversible, and unchanged nitrogen and hydrogen are recycled.
Adorable animal families that will make you aww. Lateral flexion is the anatomical term for the movement of bending sideways at the waist. Alternately known as side bending or lateral trunk flexion, it can refer to movement of the entire spine in a lateral direction, of the neck only, or of a segment of the spine.his is because lateral flexion affects entire portions of the spine, not just two adjacent vertebrae. Side bending from the waist involves movement in both the thoracic and lumbar spine; laterally flexing the head requires the involvement of most of the cervical spine.
Inversion is where the sole of the foot is turned inwards, plantar flexion is where the foot and toes point downwards and adduction of the ankle involves the toes pointing across the body. Combine all three movements and you have supination.When standing, supination occurs as the foot rolls outwards, placing most of the weight onto the outside of the foot and raising the arch. Supination is a normal part of the gait cycle (walking/running) which allows the foot to form a rigid structure for propulsion.The opposite movement to supination is pronation, this is also a normal part of the gait cycle and when excessive is termed overpronation.nversion is where the sole of the foot is turned inwards, plantar flexion is where the foot and toes point downwards and adduction of the ankle involves the toes pointing across the body. Combine all three movements and you have supination.
