sector (PEM‚ 2003). As stated in the EMB report‚ domestic wastewater discharges contribute highest to the BOD load as the lack of sewage treatment system allows more than 90 percent of inadequately treated domestic sewage to be discharged into surface waters‚ which contain bacteria and viruses that threaten human life. Geographically‚ data show that one-third (30 percent) of BOD generation comes from Metro Manila and Region IV alone‚ at 18 and 15 percent‚ respectively (PEM‚ 2003). Industrial wastewater

Potential and Kinetic Energy Transformations Potential and kinetic energy can be found in things all around us‚ especially in roller coasters. Potential energy is stored energy in an object‚ and kinetic energy is energy of motion or speed. On a rollercoaster it can switch from potential to kinetic energy very often. The rollercoaster starts off with a chain and motor and exerts a force on the rollercoaster which pushes the ride to the top of the hill. Throughout the process of going up the hill

carries important information through action potential‚ this is significant activity of the neurons to allow us to understand abnormality in the nerve that cause disorders. The objective of this study was to trigger a compound nerve action potentials (CAPs) and examine the effects of a stimulus voltage on a nerve and inspect their threshold‚ refractory period and also their velocity. Compound nerve action potentials (CAPs) are summed action potential of one nerve‚ one nerve consists of many neurons
