capacity of our lungs is the volume of air our lungs can hold. Our lungs have a greater capacity than we use when we take a normal breath. Scientists use various terms to describe the different components of lung capacity. Tidal Volume is the amount of air breathed out in a single normal breath (inhalation and exhalation). The Inspiratory Reserve Volume is the amount of air you can inhale over and above a normal breath. The Expiratory Reserve Volume is the volume of air forced out of the lungs

STABILITY OF A FLOATING BODY Introduction It is important to know if a body is stable like a ship floating on the surface of a liquid and the stability depends on the height of the center of gravity. In this experiment‚ the stability of a pontoon will be found by changing its center of gravity at different heights which we can then use to compare to the theoretical stability that was calculated. Theory To find out if the floating body is stable‚ this experiment is to find out the metacentric

A study and experiment had been conducted to real subject in obtaining the real time result and brain mapping of the activity in human brain. Electric Capacitance Volume Tomography (ECVT) were used to measure electrical signals generated from human brain activity and reconstruct volumetric image of the brain signal in real time. ECVT is a method for determination of the dielectric permittivity distribution in the

The human body is the entire structure of a human being and comprises a head‚ neck‚ trunk (which includes the thorax and abdomen)‚ arms and hands‚ legs and feet. Every part of the body is composed of various types of cell.[1] At maturity‚ the estimated average number of cells in the body is given as 37.2 trillion. This number is stated to be of partial data and to be used as a starting point for further calculations. The number given is arrived at by totalling the cell numbers of all the organs
