Black Holes: Facts, Theory & Definition. Black holes are some of the strangest and most fascinating objects found in outer space. They are objects of extreme density, with such strong gravitational attraction that even light cannot escape from their grasp if it comes near enough.
Chemigation is the injection any chemical such as nitrogen, phosphorus or a pesticide into irrigation water and applied to the land using the irrigation system. The proper use of chemigation is recognized as a Best Management Practice (BMP) for irrigated agriculture.
Centrifugation Theory. Centrifugation is a process used to separate or concentrate materials suspended in a liquid medium. The theoretical basis of this technique is the effect of gravity on particles (including macromolecules) in suspension.Two particles of different masses will settle in a tube at different rates in response to gravity. commonly used technique for cell fractionation, called differential centrifugation, is used to separate particles from a liquid medium or to separate particles of different masses into separate fractions of the supernatant.
