These names have applied to a part or the whole of the Levant. On occasion, two or more of these names have been used at the same time by different cultures or sects. As a natural result, some of the names of the Levant are highly politically-charged. Perhaps the least politicized name is Levant itself, which simply means "where the sun rises" or "where the land rises out of the sea", a meaning attributed to the region`s easterly location on the shore of the Mediterranean Sea.

At its greatest extent, the Nanda Empire extended from Bengal in the east, to Punjab in the west and as far south as the Vindhya Range. The Nanda Empire was later conquered by Chandragupta Maurya, who founded the Maurya Empire.

(Rice University) designed and synthesized these compounds in 2003 as a part of a sequence of chemical education for young students. The compounds consist of two benzene rings connected via a few carbon atoms as the body, four acetylene units each carrying an alkyl group at their ends which represents the hands and legs, and a 1,3-dioxolane ring as the head.

The National Helium Reserve, also known as the Federal Helium Reserve, is a strategic reserve of the United States holding over a billion cubic meter (1E9 m3) of helium gas. The helium is stored at the Cliffside Storage Facility about 12 miles (19 km) northwest of Amarillo, Texas, in a natural geologic gas storage formation, the Bush Dome reservoir. The reserve was established in 1925 as a strategic supply of gas for airships, and in the 1950s became an important source of coolant during the Space Race and Cold War.

It blocks the effects of GHB in animals and has both anti-sedative and anticonvulsant effects. It has been proposed as a treatment for GHB overdose in humans, as well as for the endogenous metabolic disorder succinic semialdehyde dehydrogenase deficiency, but has never been developed for clinical use.

Neon lights are a type of cold cathode gas-discharge light. A neon tube light is a sealed glass tube with a metal electrode at each end, filled with one of a number of gases at low pressure. A high potential of several thousand volts applied to the electrodes ionizes the gas in the tube, causing it to emit colored light by fluorescence. The color of the light depends on the gas in the tube. Neon lights were named for neon, a noble gas which gives off a popular red light, but other gases and chemicals are used to produce other colors, such as helium (yellow), carbon dioxide...
High Quality Content by WIKIPEDIA articles! Neutronium is a proposed name for a substance composed purely of neutrons. The word was coined by scientist Andreas von Antropoff in 1926 (before the discovery of the neutron itself) for the conjectured "element of atomic number zero" that he placed at the head of the periodic table. However, the meaning of the term has changed over time, and from the last half of the 20th century onward it has been used legitimately to refer to extremely dense phases of matter resembling the neutron-degenerate matter postulated to exist in the cores of neutron stars. Science fiction and popular literature frequently use the term "neutronium" to refer to a highly dense phase of matter composed primarily of...
High Quality Content by WIKIPEDIA articles! Neutron generators are neutron source devices which contain compact linear accelerators and that produce neutrons by fusing isotopes of hydrogen together. The fusion reactions take place in these devices by accelerating either deuterium, tritium, or a mixture of these two isotopes into a metal hydride target which also contains deuterium, tritium or a mixture of these isotopes. Fusion of deuterium atoms (D + D) results in the formation of a He-3 ion and a neutron with a kinetic energy of approximately 2.5 MeV. Fusion of a deuterium and a tritium atom (D + T) results in the formation of a He-4 ion and a neutron with a kinetic energy of approximately 14.1 MeV.

These can be studied by interpreting the temporal frequency spectrum acquired through observations. In the same way, the more extreme neutron stars might be studied and hopefully give us a better understanding of neutron-star interiors, and help in determining the equation of state for matter at nuclear densities. Scientists also hope to prove, or discard, the existence of so called quark stars, or strange stars, through these studies.

In animal studies it has anxiolytic, antidepressant and anorectic effects, and it has successfully passed Phase I clinical trials in humans.
High Quality Content by WIKIPEDIA articles! Niaprazine (Nopron) is a sedative-hypnotic drug of the phenylpiperazine class. It has been used in the treatment of sleep disturbances since the early 1970s in several European countries, including France, Italy, and Luxembourg. It is commonly used with children and adolescents on account of its favorable safety and tolerability profile and lack of abuse potential.
