Expert Author: Vara Lakshmi Circuit Breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and, by interrupting continuity, to immediately discontinue electrical flow. Expert Author: Vara Lakshmi A transformer is a device that transfers electrical energy from one circuit to another through inductively coupled conductors-the transformer's coils. A varying current in the first or primary winding creates a varying magnetic flux in the transformer's core, and thus a varying magnetic field through the secondary winding. Expert Author: Vara Lakshmi Gearbox provides speed and torque conversions from a rotating power source to another device using gear ratios. Planetary gearing is a gear system that consists of one or more outer gears, or planet gears, revolving about a central, or sun gear. Typically, the planet gears are mounted on a movable arm or carrier which itself may rotate relative to the sun gear. Planetary gearing systems also incorporate the use of an outer ring gear or annulus, which meshes with the planet gears. The axes of all gears are usually parallel, but for special cases like pencil sharpeners they can be placed at angle, introducing elements of bevel gear. Expert Author: Alexander Sutton Distance learning has been around since long before the days of the Internet. It used to be called correspondence courses. People would sign up to take a course and communicate with their instructor through the mail. This model is still in place today but the mail has been changed to online platforms. Expert Author: Alex Shown Hey, do you want to try your hand at theatre? Performing in front of a huge audience and living up to their expectations is anything but easy. Most actors have an impending fear of stage fright. Even top performers and actors have experienced stage fright at some point of their lives. Some people tend to throw up before a performance, some go blank when they are actually on the stage, others experience shaking and numbness of the body. Expert Author: Diana Valentine Facial EMG tests essentially measure minute muscle contractions on the face of the commercial viewer. Results from the test elicit an overall positive and negative emotional activation score. By measuring a dynamic emotional response to a commercial, useful insights about the elements of the commercials are gained that in turn help marketers create successful campaigns. Expert Author: Anir Ban Animation is a field, which is grabbing the attention of the youngsters with its growing popularity. The usage of elements like animated cartoons and multimedia in every movie or advertisement these days, have boosted the interests of the common man in the field of animation and gaming. The talks about animated games and movies everywhere, has a great impact on the minds of the students, because of which they want to take it as their career. Expert Author: Anir Ban Educational qualification is a very important asset for having a well structured and a planned future for a human being. Students always have set priorities for their future, due to which they need to work hard and move according to the plans formed. The aim of every job or career field is to earn sufficient amount of money, from which the person and his family can live a healthy life.

NAFSA is one such organization. It serves the field of international education by providing grant opportunities to overseas educational advisers. By educational advisers we mean the people who work with students, scholars and trainees interested in education, research and training in the United States. A vital role is played by them in the development of services and opportunities for NAFSA members. Expert Author: Lauren Z Parks and large public places are often the most challenging part of a cleaning professional's job. Because of the large area and high traffic, it is often difficult to clean these facilities quickly and effectively. Without the proper equipment, it is not only difficult to remove hardened and decayed chewing gums, it is nearly impossible. The residue can stay around for several years becoming even more difficult to remove. Gum residue left behind may even damage structures such as benches and statues. Expert Author: Daren Kyle To be in Spain is fascinating, to study Spanish is exhilarating! Visiting a place is superficial limiting knowledge to what the senses perceive. There is but more to explore than the exterior appeal of a territory that is implied in language. This is a validated truth as language is an actual testimony so make your testimony out of it, too. Expert Author: Jamie S Hanson People often get fascinated by the world of arts. There are extremely well noted personalities who have gained the name and even fame in the world of art. Among all other popular arts, the most popular art is paiting. Painting is such a compelling art that is considered to be one of the ideal ways to convey our ideas, feelings, etc... Expert Author: Thierry P. Nihill colleges "legitimate" post-secondary institutions. At least, the Toronto Transit Commission (TTC), the governing body that creates and enforces policy for the largest public transportation system in Canada, doesn't see the legitimacy in granting private career college students discounted monthly passes. Expert Author: Anir Ban The increasing consciousness about health and the necessity for being fit, has given a push to the courses related to health and fitness. There have been many practises followed in the ancient India, which are again coming into use, due to its benefits getting highlighted. Medicines coming out of the allopathic practise of doctrine are believed to have side effects on the human body, which comes out as immediate or lingered on effects. Expert Author: Allan Smith Teaching at its best is a delicate balancing act. Teachers, like skillful tightrope walkers, must often teeter between what they know is good pedagogical practice, what their students need and want, what their students' parents demand, and what school administrators ask them to do. Finding alignment among their many requisite tasks may seem challenging, if not downright impossible. Expert Author: Allan Smith Our audience may query 'Why write a commentary about censorship using three metaphors' Unequivocally; censorship is an 'old' topic that has been mulled over time and time again. And like many old topics, it could be easily dismissed because many people might argue that the issue has been examined, discussed, thought about, and when problems related to it emerge, resolved. To remind us that censoring books is no dead issue, Muzevich (2008) noted, 'The Office for Intellectual Freedom (OIF) of the American Library Association (ALA) recorded 3,019 challenges between Jan 1, 2000 and December 31, 2005.' Expert Author: Donny Gamble Jr The Gates foundation grants are named after Bill Gates and Melinda Gates. It is considered to be the largest private foundation in the entire world. The very reputed lineage of the Gates family runs this foundation. The Gates foundation grant performs with certain goals. It aims at fulfilling the needs of the deprived and wishes to reduce the poverty. Expert Author: Allan Smith One way to merge imagination with problem-posing and problem-solving in the English classroom is by asking students to respond to what I term cultural and political vignettes or CPVs. CPVs are cultural and political situations that are presented to students so that they can practice the creative and essential decision-making skills that they will need to use in diverse classrooms and communities. CPVs deal with sensitive cultural and political issues, such as race, class, gender, ethnicity, school politics, and sexual orientation, and are designed to ask respondents to reflect on their values, ideologies, biases, philosophies, and, ultimately, their subsequent actions. Expert Author: Allan Smith I would never in my life let anyone get bullied while I watched or walked by because I know what it feels like to be bullied, since I was bullied in kindergarten. First, I would tell the eighth grader to stop, and if he didn't, I would step in front of the seventh grader to block him so he wouldn't get hurt. -Daniel
