Nitrous oxide, commonly known as laughing gas or nitrous, is a chemical compound, an oxide of nitrogen with the formula N2O. At room temperature, it is a colorless non-flammable gas, with a slightly metallic scent and taste. At elevated temperatures, nitrous oxide is a powerful oxidizer similar to molecular oxygen.Nitrous oxide has significant medical uses, especially in surgery and dentistry, for its anaesthetic and analgesic effects.

Nittatsu Hosoi (細井日達, Hosoi Nittatsu; 15 April 1902, Tokyo — 22 June 1979) was the 66th high priest of Nichiren Shoshu, a major school of Nichiren Buddhism, and chief priest of its head temple Taisekiji in Fujinomiya, Shizuoka, Japan. He was succeeded by Nikken Abe after his death.

Nittaewo (or Nittevo) were said to be a small tribe of small bigfoot or Yeti like hominid Cryptid native to Sri Lanka.Legends of the Veddha tribe, who still farm in Sri Lanka, say they are responsible for wiping out the Nittaewo sometime in the late 18th century. According to the Veddha tradition recorded by Frederick Lewis in 1914, the Nittaewo were approximately three feet (1 metre) tall, the females being shorter than the males. They walked erect, had no tails and were completely naked.

Nitrous Oxide Fuel Blend propellants are a class of liquid rocket propellants intended to replace hydrazine as the standard rocket fuel. The fuel and oxidizer are blended and stored; this is sometimes referred to as a mixed monopropellant. Upon use, the propellant is heated or passed over a catalyst bed and the nitrous oxide decomposes into oxygen-rich gasses. Combustion then ensues. Special care is needed in the chemical formulation and engine design to prevent detonating the stored fuel.

Nitroxylic acid or hydronitrous acid is an unstable reduced oxonitrogen acid. It has formula H4N2O4 containing nitrogen in the +2 oxidation state. The corresponding anion called nitroxylate is N2O4−4 or NO2−2.The first clue that nitroxylic acid exists was when Edward Bedford Maxted electrolysed sodium nitrite dissolved in liquid ammonia. A bright yellow substance deposited on the cathode. He called this disodium nitrite. The disodium nitrite could also be made by mixing ammonia solutions of sodium and sodium nitrite in the complete absence of water. Disodium nitrite reacts with water to form sodium nitrite, sodium hydroxide and hydrogen. Other ways to make the disodium nitrite include reacting sodium with ammonium nitrate or electrolysing sodium nitrate solution. Note that the disodium nitrite is very explosive, and experimenters often had their apparatus destroyed when making it. Disodium nitrite reacts with oxygen and carbon dioxide explosively. The substance is nowadays called sodium nitroxylate and has CAS number 13968-14-4.Lithium sodium nitroxylate LiNaNO2 also exists and explodes at 130°C.Nitroxylic acid might be produced when nitrous acid is reduced by the europium2+ ion.

Nitromifene (INN; also as the citrate salt nitromifene citrate (USAN), developmental code names CI-728, CN-5518, CN-55945) is a nonsteroidal selective estrogen receptor modulator (SERM) related to triphenylethylenes like tamoxifen that was never marketed. It is a mixture of (E)- and (Z)-isomers that possess similar antiestrogenic activity. The drug was described in 1966. Along with tamoxifen, nafoxidine, and clomifene, it was one of the earliest SERMs.

Nittaewo (or Nittevo) were said to be a small tribe of small bigfoot or Yeti like hominid Cryptid native to Sri Lanka.Legends of the Veddha tribe, who still farm in Sri Lanka, say they are responsible for wiping out the Nittaewo sometime in the late 18th century. According to the Veddha tradition recorded by Frederick Lewis in 1914, the Nittaewo were approximately three feet (1 metre) tall, the females being shorter than the males. They walked erect, had no tails and were completely naked. Their arms were short, with talon-like nails. They lived in trees, caves and crevices and caught and ate small animals such as hare, squirrel and tortoise. They lived in groups of 10 or 20 and their speech was like the twittering of birds. They fought constantly with the Veddha; when they began to take Veddha children, the Veddha trapped the Nittaewo in a cave and blocked its entrance with a wood fire, killing them all. This account was recorded in 1887 by British explorer Hugh Nevill.British primatologist W.C. Osman Hill led an expedition into the region in 1945 and found widespread belief in the Nittaewo still being alive on the island. He concluded that Dubois's Pithecanthropus erectus of Java, also known as the Java Man, which has since been renamed Homo erectus, matched the traditions and descriptions of the Nittaewo.Captain A.T.Rambukwella theorised that the Nittaewo may have been a species of Australopithecus, described as small, man-like non-human apes who stood erect and had a bipedal gait. He led an expedition to the Mahalenama area in search of the Nittaewo in May 1963. During an excavation of a cave at Kudimbegala they discovered, at a depth of ten inches (25 cm), the vertebrae of a monitor lizard and a piece of a carapace of a star tortoise both said to be part of the diet of the Nittaewo.Dr. Salvador Martinez, Spanish anthropologist, claimed to have seen a Nittaewo in Sri Lanka in 1984, though he did not report the incident for many years. According to him, the Nittaewo had a human appearance; its body appeared covered with a coat of long hair, with signs of scabs in some areas. Martinez remembers that the Nittaewo began to emit unintelligible sounds before fleeing toward the denseness of the forest. However, people have said he was mistaken and it was simply a member of a local nomad tribe.In October 2004, the discovery of fossils of a proposed new species of the genus Homo, on the Indonesian island of Flores, gave new weight to the possibility of small human or ape-like species living amongst us in recent times.

Nitroglycerin, also known as glyceryl trinitrate (GTN) is a medication used for heart failure, high blood pressure, and to treat and prevent chest pain from not enough blood flow to the heart or due to cocaine. This includes chest pain from a heart attack. It is taken by mouth, under the tongue, applied to the skin, or by injection into a vein.Common side effects include headache and low blood pressure. The low blood pressure can be severe.

Nitrous oxide, commonly known as laughing gas or nitrous, is a chemical compound, an oxide of nitrogen with the formula N2O. At room temperature, it is a colorless non-flammable gas, with a slightly metallic scent and taste. At elevated temperatures, nitrous oxide is a powerful oxidizer similar to molecular oxygen.Nitrous oxide has significant medical uses, especially in surgery and dentistry, for its anaesthetic and analgesic effects. Its name "laughing gas" is due to the euphoric effects upon inhaling it, a property that has led to its recreational use as a dissociative anaesthetic. It also is used as an oxidizer in rocket propellants, and in motor racing to increase the power output of engines.Nitrous oxide occurs in small amounts in the atmosphere, but recently has been found to be a major scavenger of stratospheric ozone, with an impact comparable to that of CFCs. It is estimated that 30% of the N2O in the atmosphere is the result of human activity, chiefly agriculture.

The nitronium ion, NO+2, is a cation. It is an onium ion because of its tetravalent nitrogen atom and +1 charge, similar in that regard to ammonium. It is created by the removal of an electron from the paramagnetic nitrogen dioxide molecule, or the protonation of nitric acid (with removal of H2O).It is stable enough to exist in normal conditions, but it is generally reactive and used extensively as an electrophile in the nitration of other substances. The ion is generated in situ for this purpose by mixing concentrated sulfuric acid and concentrated nitric acid according to the equilibrium:H2SO4 + HNO3 → HSO−4 + NO+2 + H2O

This includes chest pain from a heart attack. It is taken by mouth, under the tongue, applied to the skin, or by injection into a vein.Common side effects include headache and low blood pressure. The low blood pressure can be severe. It is unclear if use in pregnancy is safe for the baby. It should not be used together with medications within the sildenafil (PDE5 inhibitor) family due to the risk of low blood pressure. Nitroglycerin is in the nitrate family of medications. While it is not entirely clear how it works, it is believed to function by dilating blood vessels.Nitroglycerin was written about as early as 1846 and came into medical use in 1878. It is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system. The wholesale cost in the developing world as of 2014, was US$0.06–0.22 per dose by mouth. The drug nitroglycerin (GTN) is a formulation of the same chemical substance used as the explosive nitroglycerin.

Nitrosopumilus maritimus is an extremely common archaeon living in seawater. It is the first member of the Group 1a Crenarchaeota to be isolated in pure culture. Gene sequences suggest that the Group 1a Crenarchaeota are ubiquitous with the oligotrophic surface ocean and can be found in most non-coastal marine waters around the planet. It is one of the smallest living organisms at 0.2 micrometers in diameter. It lives by oxidizing ammonia to nitrite. N. maritimus is capable of oxidizing ammonia at levels as low as 10 nanomolar, near the limit to sustain its life. This organism was isolated from sediment in a tropical tank at the Seattle Aquarium by a group led by David Stahl (University of Washington). In taxonomy, "Candidatus Nitrosopumilus" is a genus of the Nitrosopumilaceae.

The Nittany Lion is the mascot of Pennsylvania State University in University Park, Pennsylvania, USA and its athletic teams. It refers to the mountain lions that are thought to have once roamed Mount Nittany, a local landmark. There is a song played during sporting events on campus entitled "The Nittany Lion." Fans know this song as Hail to the Lion, even though that is not technically the name of the song.The mascot was the creation of Penn State senior H. D. "Joe" Mason in 1907 since the Nittany Lion is not a real animal. While on a 1904 trip to Princeton University, Mason had been embarrassed that Penn State did not have a mascot. Mason did not let that deter him: he fabricated the Nittany Lion on the spot and proclaimed that it would easily defeat the Princeton Bengal tiger. The Lion's primary means of attack against the Tiger would be its strong right arm, capable of slaying any foes (this is now traditionally exemplified through one-armed push-ups after the team scores a touchdown). Upon returning to campus, he set about making his invention a reality. In 1907, he wrote in the student publication The Lemon:Mountain lions had roamed on nearby Mount Nittany until the 1880s. The origin of the name "Mount Nittany" is obscure, the most commonly accepted explanation being that it is derived of Native American words (loosely pronounced as "neet-a-nee") named after the cougars that roamed the mountain or "single mountain" - a protective barrier against the elements.. The "original" nittany lion can be seen in the Penn State All-Sports Museum as the only known mounted eastern mountain lion. It was killed in Susquehanna County by Samuel Brush in 1856. According to a July 1992 article in National Geographic by Maurice Hornocker titled "Learning to Live with Mountain Lions", "Courthouse records from Centre County, Pennsylvania, show that one local hunter killed 64 lions between 1820 and 1845. During those 25 years an estimated 600 cats were killed in that county alone."
