Psychosensory therapy and texture. Touch is a form of nonverbal communication that can have an extrasensory effect. The use of touch has been long associated with healing. For instance, acupuncture needling, an ancient practice in traditional Chinese medicine (TCM) and a touch therapeutic technique, deals with the insertion of needles into the skin in order to affect one’s mood and perception of pain. Reiki, a Japanese touch technique, deals with movement of hands on the body and is often used for stress reduction. Massage therapy involves kneading different parts of the body with some pressure. This form of touch therapy breaks down
Lagrangian and Eulerian specification of the flow field its Eulerian specification u is equal to the sum of the local rate of change and the convective rate of change of F. This is a consequence of the chain rule since we are differentiating the function F(X(x,"t"),"t") with respect to "t". Conservation laws for a unit mass have a Lagrangian form, which together with mass conservation produce Eulerian conservation; on the contrary, when fluid particles can exchange a quantity (like energy or momentum), only Eulerian conservation laws exist. Lagrangian and Eulerian specification of the flow field In classical field theory the Lagrangian specification of the field is a way
