For the high-altitude lake in Lassen Volcanic National Park, see Lake Helen ( Lassen Peak )

For the next six years he worked on high-altitude structural ironwork throughout the United States for various companies, including General Motors and U. S. Steel.

For information about the airships, please see high-altitude airship.

For air-to-air use this allowed the missile to be " lofted " above the target and then be directed down towards it as it approached ; this gives the missile greater range as it spends more time in thinner high-altitude air.

For example, on the eve of the Meuse offensive, Guderian's superior cancelled his CAS plans and called for high-altitude strikes from medium bombers, which would have required halting the offensive until the air strikes were complete.

For several years, he and colleagues led further expeditions studying the geology, agriculture, social and family life and monastic practices in this remote, high-altitude region.

" For heavier payloads, hydrogen-fuelled high-altitude UAVs are a possibility.

For the first time in history the entire world is dominated by two large, powerful nations armed with murderous nuclear weapons that make conventional warfare of the past a nullity.

For an example of its use, analysis of the concentration of elements is important in managing a nuclear reactor, so nuclear scientists will analyze neutron activation to develop discrete measurements within vast samples.

For example, californium can be used to help start up nuclear reactors, and it is employed as a source of neutrons when studying materials with neutron diffraction and neutron spectroscopy.

For example, in the 19th century, the Sun appeared to be no more than 20 million years old, but the Earth appeared to be no less than 300 million years ( resolved by the discovery of nuclear fusion and radioactivity, and the theory of quantum mechanics ); or current attempts to resolve theoretical differences between quantum mechanics and general relativity.

For example, in Shadowrun, a tactical nuclear device was detonated near FASA's offices at 1026 W. Van Buren St in Chicago, Illinois.

For years, Seatopia, the undersea civilization, has been heavily affected by nuclear testing conducted by the surface nations of the world.

Sociologist Mary Bernstein writes: " For the lesbian and gay movement, then, cultural goals include ( but are not limited to ) challenging dominant constructions of masculinity and femininity, homophobia, and the primacy of the gendered heterosexual nuclear family ( heteronormativity ).

For autoradiography on a microscopic level, the slide is typically dipped into liquid nuclear tract emulsion, which dries to form the exposure film.

For example, introns are extremely common within the nuclear genome of higher vertebrates ( e. g. humans and mice ), where protein-coding genes almost always contain multiple introns, while introns are rare within the nuclear genes of some eukaryotic microorganisms, for example baker's / brewer's yeast ( Saccharomyces cerevisiae ).

For example, the effectively limitless availability of energy that would result from the development of controlled nuclear fusion would make it unnecessary to limit access to energy resources.

For related reasons, lithium has important links to nuclear physics.

For example, a radioactive isotope lutetium-176 is used in nuclear technology to determine the age of meteorites.

For example, animals undergo an " open " mitosis, where the nuclear envelope breaks down before the chromosomes separate, while fungi such as Aspergillus nidulans and Saccharomyces cerevisiae ( yeast ) undergo a " closed " mitosis, where chromosomes divide within an intact cell nucleus.

For example, an explosion is the result of a chain reaction that transforms potential energy stored in chemical, mechanical, or nuclear form into kinetic energy, acoustic energy, and electromagnetic radiation.

For larger nuclei, however, no energy is released, since the nuclear force is short-range and cannot continue to act across still larger atomic nuclei.

For a more detailed description of the physics and operating principles of critical fission reactors, see nuclear reactor physics.

For a description of their social, political, and environmental aspects, see nuclear power.

For example, power plants licensed in the United States require a negative void coefficient of reactivity ( this means that if water is removed from the reactor core, the nuclear reaction will tend to shut down, not increase ).

For example, advances in the understanding of electromagnetism or nuclear physics led directly to the development of new products which have dramatically transformed modern-day society, such as television, computers, domestic appliances, and nuclear weapons ; advances in thermodynamics led to the development of industrialization ; and advances in mechanics inspired the development of calculus.

For instance, in a hydrogen Maser, the well-known " 21cm wave " transition in atomic hydrogen, where the lone electron flips its spin state from parallel to the nuclear spin to antiparallel, can be used to create a population inversion because the parallel state has a magnetic moment and the antiparallel state does not.

For many eukaryotic introns, splicing is done in a series of reactions which are catalyzed by the spliceosome, a complex of small nuclear ribonucleoproteins ( snRNPs ), but there are also self-splicing introns.

For example, among its policies are a commitment to unilateral nuclear disarmament, progressive personal taxation, the eradication of poverty, free state education including support grants for higher education students and a pay increase for nurses.

For example, Phil South inserted single, completely white frames into his work No Licence to enhance the visual impact of explosions.

For this reason, rock dusts such as limestone dust are spread throughout coal mines to diminish the chances of coal dust explosions as well as to limit the extent of potential explosions, in a process known as rock dusting.

For example, in 2008 the United States Defense Advanced Research Projects Agency used live pigs to study the effects of improvised explosive device explosions on internal organs, especially the brain.

For high altitude nuclear explosions, these electrons are captured in the Earth's magnetic field at altitudes between twenty and forty kilometers where they interact with the Earth's magnetic field to produce a coherent electromagnetic pulse ( EMP ) which lasts about one millisecond.

For instance, methane explosions enforced the Peshtigo Fire.

For example, Dicker implemented a particle effect algorithm to generate unique explosions for destroyed enemies.

For one caught in the open, and by surprise, by the same 1 megaton weapon detonation, but one ducked and covered in 2 seconds time from first noticing the moment of flash, then one would have prevented themselves from being exposed to the full brunt of the 1 megaton explosions thermal energy, instead, approximately 55 % of the explosions total thermal flash energy would have been absorbed over these 2 seconds In this example, as there is now a 45 % reduction in the amount of heat experienced by one ducking and covering, the 50 % lethal thermal range from this 1 megaton weapon can now be more accurately equated to equivalent to the entire flash energy from a 0. 55 Mt or 550 kt weapon, if one ducks and covers in 2 seconds, and no longer treated as a 1 megaton weapon.

For example, explosions near or within hard solid surfaces become amplified two to nine times due to shock wave reflection.

For example, people may survive imminent explosions by being in a bunker or evacuating.

For instance, the Star Trek franchise kept a large collection of starships, planets, backgrounds and explosions which would appear on a regular basis throughout Star Trek's five series and ten films, being used with minimal alteration.

For example, the Yellowstone Caldera was formed by some of the most powerful volcanic explosions in geologic history.

For example, footage of real smoke was used for explosions.

For example, oxidation of cyclohexane into cyclohexanol and cyclohexanone and ortho-xylene into phthalic anhydride have led to catastrophic explosions when reaction control failed.
