The Laplace transform is one of the most important tools used for solving ODEs and specifically, PDEs as it converts partial differentials to regular differentials as we have just seen. In general, the Laplace transform is used for applications in the time-domain for t ≥ 0
Which course is Laplace transform?
Laplace transform is a fundamental tool in integral calculus. It is used to solve various types of differential equations, difference equations, integral equations etc., which arise naturally in engineering and basic sciences
A sphygmomanometer is a device that measures blood pressure. It comprises of an inflatable rubber cuff, which is wrapped around the arm and a measuring device that indicates the cuff's pressure. A bulb inflates the cuff and a valve releases pressure. It is used in conjuction with a stethoscope to listen to arterial blood flow sounds.
Diathermy is a therapeutic treatment commonly prescribed for muscular and joint associated pains. The term ‘diathermy’ means ‘through heating’ or producing deep heating directly in the tissues of the body. ‘ Dia’ through (also means two) ‘thermy’ heat or temperature It simulates the circulation, relieve pain, enhances rate of recovery of healing the tissue.
PRINCIPLE OF DIATHERMY
1. Before injury, the dipole molecules of the body tissue are arranged on the basis of polarity . 2. When the tissue is damaged the dipoles distribution become irregular and deviates from polarity based arrangement . 3. Under the influence of an electric field , they rotate according to the polarity of their charge in the direction of the field lines and get rearranged and tends to acquire its previous stage of polarity
