Defn. of Digestion: the process whereby a biological entity processes a substance‚ in order to chemically convert the substance into nutrients. It usually involves mechanical manipulation and chemical action. Mechanical Digestion What is it? This type of digestion involves the mixing‚ grinding or crushing of large pieces of food into smaller places. Why does it take place? So that the food we consume is broken down into smaller pieces before we swallow it which in turn makes process of

Sound is a vibration that spreads across a medium (i.e.‚ air or water) as a mechanical longitudinal wave formed by pressure. A Mechanical longitudinal wave can also be called compression wave as it generates compressions and rarefaction when traveling through a medium. (Sound Is a Pressure Wave - Physics Classroom) The amplitude of a sound wave is the difference between the pressure of the undisturbed air and the maximum pressure caused by the wave. The Speed of sound deviates with the temperature

need to focus and concentrate . Focus and concentration greatly affect the things a student learns. For this reason we must find and eradicate the things that causes discomfort to the students. And one of which is the inadequate or poor supply of ventilation that in some part of CAYSMNHS seemed inadequate. For instance is the room of Four-Love students‚ students their complain for a high room temperature compared to other classrooms. Slowly but surely is the motto of some teacher in CAYSMNHS. This

to Reduce Ventilation Costs Ventilation can account for 30-40% of the total energy operating cost in mines (Mining‚ n.d.). That being said‚ the slightest amounts of change within this aspect of the mines can make a significant difference in costs. One of the biggest trends in the mining industry as of late is to switch from the conventional diesel-powered equipment to the newer electric powered machines offered on the market. This switch can make a significant impact on the ventilation requirements
