The Water Cycle: The U.S. Geological Survey explains what the water cycle is and where water comes from. Animated Water Cycle: This animated water cycle diagram allows kids to click on different parts of the cycle to see how water changes form and moves.
The neuromuscular junction (NMJ) is the site of communication between motor nerve axons and muscle fibres. It is composed of four specialised cell types: motor neurons, Schwann cells, muscle fibres and the recently discovered kranocytes.
Uses of NMR spectroscopy. Nuclear Magnetic Resonance (NMR) spectroscopy is an analytical chemistry technique used in quality control and reserach for determining the content and purity of a sample as well as its molecular structure.For example, NMR can quantitatively analyze mixtures containing known compounds.he basis of NMR. The principle behind NMR is that many nuclei have spin and all nuclei are electrically charged. If an external magnetic field is applied, an energy transfer is possible between the base energy to a higher energy level (generally a single energy gap).
