  • liquid nitrogen
  • A cold explosion can be produced by placing liquid nitrogen in a film can. (gsu.edu)
  • Artificial breeding services supplied in sheep, cattle and goats by way of semen processing, artificial insemination, embryo transfer, flock fertility advice, liquid nitrogen and equipment sales, and sire evaluation. (dmoztools.net)
  • gaseous
  • Nitrogen is the largest single component of the Earth's atmosphere (78.084% by volume, 75.5% by weight) and is acquired for industrial purposes by the fractional distillation of liquid air or by mechanical means of gaseous air (i.e. (factbites.com)
  • fixation
  • This web site is not designed to be a comprehensive presentation on nitrogen fixation, but rather it is intended as a forum to present informative images that are not otherwise easily available. (reed.edu)
  • metabolism
  • Our results show that diatoms can remodel their intermediate metabolism on environmental cues and reveal that a key signal in this remodeling is associated with nitrogen assimilation. (pnas.org)
  • atom
  • The instability of NI 3 and NI 3 · NH 3 can be attributed to the large steric strain caused by the three large iodine atoms being held in proximity to each other around the relatively tiny nitrogen atom. (wikipedia.org)
  • Cycle
  • The movement of nitrogen between the atmosphere , biosphere, and geosphere in different forms is described by the nitrogen cycle (Figure 1), one of the major biogeochemical cycles . (factbites.com)
  • agricultural
  • Further, much of the nitrogen applied to agricultural land through fertilizers is not used by the crop and is lost as run-off into water courses or as greenhouse gases through denitrification, resulting in deleterious impacts on the environment. (nsf.gov)
  • notable
  • Many notable nitrogen-containing drugs, such as the natural caffeine and morphine or the synthetic amphetamines, act on receptors of animal neurotransmitters. (wikipedia.org)
  • toxicity
  • In addition to fueling infestations of invasive plants, such as cabomba, high nitrogen levels are also increasing the growth and toxicity of killer blue-green algae. (nature.org)
  • form
  • Nitrogen also dissolves in the bloodstream , and rapid decompression (particularly in the case of divers ascending too rapidly) can lead to a potentially fatal condition called decompression sickness , when nitrogen bubbles form in the bloodstream . (factbites.com)
  • species
  • Research has also suggested the nodules on nitrogen-fixing trees transfer nitrogen directly to the roots of other trees growing nearby, so you get double-duty from planting these special species. (independent.com)
  • A living fence or hedge of one or more of these species can be harvested repeatedly for its nitrogen-rich clippings (all without any additional fertilizer inputs from you). (independent.com)
  • And if you rely on a wood-burning source of heat in winter, there are woody species that can provide more than the nitrogen from green, leafy parts, but can also be cut for their wood. (independent.com)
  • fertilizer
  • The aspiration is that mixing researchers from diverse scientific backgrounds will engender fresh thinking and new approaches that can be used to increase nitrogen availability to crop plants whilst maintaining or increasing yield, and hence decrease the need for the application of fertilizer. (nsf.gov)
  • found
  • The name nitrogène was suggested by French chemist Jean-Antoine-Claude Chaptal in 1790, when it was found that nitrogen was present in nitric acid and nitrates. (wikipedia.org)
  • stress
  • Under nitrogen stress, the cells cannibalized their photosynthetic apparatus while recycling intracellular nitrogen and redirecting it to synthesize nitrogen assimilation enzymes. (pnas.org)
  • signal
  • Many drugs are mimics or prodrugs of natural nitrogen-containing signal molecules: for example, the organic nitrates nitroglycerin and nitroprusside control blood pressure by metabolizing into nitric oxide. (wikipedia.org)
