reside within the nucleus. Protons have a positive charge‚ neutrons have no charge; they are neutral. Electrons reside in orbitals around the nucleus and have a negative charge. Atomic number is derived from the number of protons in an atom. Example‚ Helium‚ (H) = 1. The number of protons in an element is constant (e.g.‚ H=1‚ Ur=92) but neutron number may vary‚ so mass number (protons + neutrons) may vary. However‚ the same element may contain varying numbers of neutrons; these forms of an element

The average number of hops to reach the sink node is shown in Figure [fig_M1]. In Sink-PathCC‚ the number of hops to reach the sink node does not change significantly with an increase on the node density. On the other hand‚ CoopSink increases the number of hops to reach the sink by over 40% when the number of nodes increases from 50 to 100. While Sink-PathCC demands for ≈7 hops to reach the sink‚ CoopSink requires nearly 17 hops when n = 100‚ an increase of nearly 142%. Clearly‚ Sink-PathCC provides

Physics & Theory • SETI o The Allen Telescope Array - The Allen Telescope Array (ATA) is a LNSD‚ also known as a “Large number of small dishes” array and is a new piece of technology to radio astronomy. What is different about it is that it is not one big dish‚ but a series of smaller dishes combined to make one larger one. - The ATA is highly effective and much cheaper for SETI to conduct more than one survey at once in the search of extra-terrestrials. - The ATA detects radio waves that can be

Input‚ Intake‚ and Output in One-Way Drawing Task By Yan Lin It is agreed that input plays a critical role in language acquisition thus researchers have done many studies on input. Without input the learner has nothing. But the question is what kind‚ form and amount of input is most useful for the language learners. Krashen (1980) has argued that the input given to the learners has to be comprehensible for acquisition to happen. He defined it as input which is slightly
