The last reason of alcohol drinking among the youth in Hong Kong is tension reduction and it is the most common excuse among them. From a survey result conducted in 2008 by The Hong Kong Federation of Youth Group‚ about 30% of students increase their pressure index during the beginning of each new academic year. It was found that the high consumption of alcohol is related to the high level of pressure index. And the frequency of drinking depends on how early the students have experienced drinking

1. What is rf technology? A. The technology in which the parameters such as amplitude‚ phase and frequency of radio frequency waves are changed so as to transmit and receive the information is known as RF technology or radio frequency technology. In this‚ the electromagnetic waves that lie in the range of 3 khz to 300 Ghz are used for the wireless communication between the two devices. The signal is modulated at the transmitter end and then the antenna converts this electrical signal into the radio

In the most simple form‚ FM digital synthesis consists of two sine waves. One is called the modulating wave and the other is called the carrier wave. The carrier wave is the only waveform that is audible. The modulating wave does just as it sounds‚ it modulates the amplitude of the carrier wave‚ and acts as a control value. The frequency of the modulating frequency controls the rate of change in the carrier wave; it controls how fast the modulation occurs in the carrier wave. And the amplitude of

Deepkia Menon works as an assistant professor of science education at Towson University in Towson‚ Maryland. Deanna Lankford is a retired outreach specialist at the University of Missouri in Columbia‚ Missouri. They conducted many experiments with a 4th grade class to prove that they have misconceptions about sound waves. They based their experiments on these common misconceptions held by elementary students: “sound can only travel through air not through solids or liquids‚ sound can travel thought
