relative there through mobile phones. It has been observed that students bringing electronic gadgets to school are distracted from their studies. Intrapersonal reaction and communication are missing because studies are immersed in texting and gaming. There is a need to conduct a study of this condition because it has been proven by the result of Annual National Test of the DepEd that students with the most electronic gadgets in the cities and towns have lower result in these tests compared to rural

However‚ as a seven-teen-year-old‚ I had forgotten about my goal and what it had meant to me to complete the ordeal for the Order of the Arrow (OA) due to new goals and priorities. Due to the persistent nagging from my parents and what they felt was right for me‚ I went through the ordeal no matter how I felt. My journey with the Order of the Arrow (OA) ordeal began at the troop meeting on a semi-cold February night at

Kristi Malone The Electronic Era was responsible for the advancement of technology. In my opinion‚ the biggest forms of technology that came were cell phones and personal computers. The invention of cell phones made it possible to communicate with others while not around a landline. It was also now possible to call for help if an emergency arose. The invention of personal computers came with the invention of the internet and made it possible to research a topic of interest without spending hours

STARBUCKS: DELIVERING CUSTOMER SERVICE In 1992 Starbucks vision was to become the “Third Place” (home‚ work and then Starbucks). The value proposition was based on high quality coffee‚ high service standards and customer intimacy all offered in a relaxed and comfortable atmosphere. The positioning was meant to appeal to a niche market of highly educated affluent customers predominantly female between the ages of 24-44 years. Starbucks did not have a dedicated marketing strategy‚ but the function

BASIC DIODE ELECTRONICS INTRODUCTION TO DIODES The p-n Junction The p-n junction is a homojunction between a p-type and an n-type semiconductor. It acts as a diode‚ which can serve in electronics as a rectifier‚ logic gate‚ voltage regulator (Zener diode)‚ switching or tuner (varactor diode); and in optoelectronics as a light-emitting diode (LED)‚ laser diode‚ photodetector‚ or solar cell. In a relatively simplified view of semiconductor materials‚ we can envision a semiconductor as having two

variuos sources simultaneously over a common channel by means of ’multiplexing’.For ex.‚ the bandwidth of speech signals is 3.3KHz.‚and transmitting N no.of speech signals simultaneously each of BW 3.3KHz causes interference.Hence‚to overcome this problem‚ each speech signal is modulated onto one of N carriers of frequencies 60KHz‚64KHz‚68KHz etc... I know that why we use Carrier of high frequency to send message signal over a long distance‚ when the frequency is low ‚ energy will be obviously low
