Ablation (Latin: ablatio – removal) is the removal or destruction of something from an object by vaporization, chipping, erosive processes, or by other means. Examples of ablative materials are described below, including spacecraft material for ascent and atmospheric reentry , ice and snow in glaciology , biological tissues in medicine and ...
Other diseases such as Guillain–Barré syndrome, stroke, and myasthenia gravis can appear similar to botulism, and special tests may be needed to exclude these other conditions. These tests may include a brain scan , cerebrospinal fluid examination, nerve conduction test ( electromyography , or EMG), and an edrophonium chloride (Tensilon ...
Dihydrogen monoxide is a name for the water molecule, which comprises two hydrogen atoms and one oxygen atom (H 2 O).. The dihydrogen monoxide parody is a parody that involves referring to water by its unfamiliar chemical systematic name "dihydrogen monoxide" (DHMO, or the chemical formula H 2 O) and describing some properties of water in a particularly concerning manner — such as the ...
During the 1970s, the expansion of irrigation projects had begun to disrupt the flow of water to the marshes; by the early 1980s, it was evident that these had significantly affected water levels. [10] Part of the Hammar Marsh was also drained in 1985 during efforts to prepare the area for oil exploration. [11]
Depletion of surface and ground water sources for public consumption (including industrial, commercial, and residential) is caused by over-pumping. Aquifers near river systems that are over-pumped have been known to deplete surface water sources as well. Research supporting this has been found in numerous water budgets for a multitude of cities.
To dispose of animal waste and other pollutants, animal production farms often spray manure (often contaminated with potentially toxic bacteria) onto empty fields, called "spray-fields", via sprinkler systems. The toxins within these spray-fields oftentimes run into creeks, ponds, lakes, and other bodies of water, contaminating bodies of water.
Much of the water reclaimed from the Everglades was sent to newly developed areas. [80] With metropolitan growth came urban problems associated with rapid expansion: traffic jams; school overcrowding; crime; overloaded sewage treatment plants; and, for the first time in south Florida's urban history, water shortages in times of drought. [81]
This concept, along with many other results of tropical deforestation from the Geist and Lambin study, can easily be applied to habitat destruction in general. Shoreline erosion: Coastal erosion is a natural process as storms, waves, tides and other water level changes occur.
