How Male and Female Students Participate in Class According to the Deborah Tannan’s article “How Male and Female Students Participate in Class‚” while men suppose it is their duty to contribute to class by speaking up‚ women do not think that they need to speak up like men do. Most women seem to speak up occasionally when they feel it only requires doing so. Even though a woman speaks up‚ then she tries to keep silent as long as possible if she feels she would be attacked. A girl communicates

project demonstrates a technique to measure the heart rate by sensing the change in blood volume in a finger artery while the heart is pumping the blood. It consists of an infrared LED that transmits an IR signal through the fingertip of the subject‚ a part of which is reflected by the blood cells. The reflected signal is detected by a photo diode sensor. The changing blood volume with heartbeat results in a train of pulses at the output of the photo diode‚ the magnitude of which is too small to be detected

Definition: Transmittal of digital signals between two or more points in a communications system. Advantages of Digital Transmission • Noise immunity • Ease of processing and combining • Ease of measuring and evaluating • Disadvantages of Digital Transmission • Requires more bandwidth • Necessitates encoding and decoding circuitry • Requires precise time synchronization • Incompatible with older analog transmission systems Pulse Modulation Pulse Modulation consists essentially of sampling

Personification is an element of literature in which an object or an animal is given human characteristics. Angelou uses personification to give the rock‚ the river‚ and the tree the ability to speak to the reader. In "On the Pulse of Morning"‚ Angelou writes " But today‚ the rock cries out to us

temperature and blood pressure before and after exercise. Blood pressure is the measure of how much pressure is put on the walls of the blood vessels when the blood is pumped through them. This is measured in two parts‚ the larger number on top is known as the systolic pressure‚ this measures the pressure as the blood is pumped away from the heart whereas the lower number (The diastolic pressure) measures the pressure as the blood returns to the heart. The normal range for a healthy blood pressure is around

therefore alcohol evaporates faster than water. (2) Vapour Pressure: Vapour Pressure: Vapour pressure depends upon the nature of liquid.Polar liquids have low vapour pressure than that of non-polae liquids at the same temperature.This is because of the‚ strong intermolecular forces between the polar molecules of liquids.For example ‚ water has less vapour pressure than that of alcohol at same temperature.

Regulation of Blood Pressure and Blood Volume One way the body regulates blood pressure and blood volume is through the body’s use of baroreceptors‚ a mechanoreceptor of the nervous system. If there were low arterial blood pressure‚ the baroreceptors in one’s blood vessels could detect this. One’s baroreceptors in the aorta and carotid sinus of the cardiac system are constantly monitoring blood pressure. They send messages containing any changes through the central nervous system to the medulla oblongata
