Most seams are sewn with backstitch, especially on curved, slanted or loose edges.

Most americium is produced by bombarding uranium or plutonium with neutrons in nuclear reactors – one tonne of spent nuclear fuel contains about 100 grams of americium.

Most known properties – such as anion formation – are in line with other halogens.

Most acid soils are saturated with aluminium rather than hydrogen ions.

Most Apiaceae are annual, biennial or perennial herbs ( frequently with the leaves aggregated toward the base ), though a minority are shrubs or trees.

Most often, she is lovingly affectionate or teasing with her prejudices.

Most modern Pueblo peoples ( whether Keresans, Hopi, or Tanoans ) assert the ancient Pueblo did not " vanish ", as is commonly portrayed in media presentations or popular books, but migrated to areas in the southwest with more favorable rainfall and dependable streams.

Most acute aphasia patients can recover some or most skills by working with a Speech-Language Pathologist.

Most people did not consider the depiction of a Brillo Box or a store-bought urinal to be art until Andy Warhol and Marcel Duchamp ( respectively ) placed them in the context of art ( i. e., the art gallery ), which then provided the association of these objects with the associations that define art.

Most naturally occurring elements exist as a mixture of isotopes, and the average atomic mass of this mixture determines the element's atomic weight.

Most extraterrestrial helium is found in a plasma state, with properties quite different from those of atomic helium.

Most commonly an MO is represented as a linear combination of atomic orbitals ( the LCAO-MO method ), especially in qualitative or very approximate usage.

Most primary cosmic rays ( those that enter the atmosphere from deep space ) are composed of familiar stable subatomic particles that normally occur on Earth, such as protons, atomic nuclei, or electrons.

Most use film, video, clips and still images from a variety of sources: American and Japanese science fiction movies of the 1950s, old newsreel footage, more modern TV news and cable show clips, atomic bomb test footage, old civil defense films, silent movie footage, 1950s social etiquette films, industrial films, clips from their various SubGenius events, self-created footage, and fan clips.

Most atomic weights are known to a precision of at least one part in ten-thousand, often much better ( the atomic weight of lithium is a notable, and serious, exception ).

Most of the known and suggested dietary elements are of relatively low atomic weight, and are reasonably common on land, or at least, common in the ocean ( iodine, sodium ):

* " The 8 Most Wildly Irresponsible Vintage Toys " -- page 1 and page 2 at Cracked. com: Includes humorous discussions of some of A. C. Gilbert's more ill-advised products for pre-teens: A glass blowing kit (# 8 ); a molten lead casting kit (# 7 ); a chemistry set (# 3 ) which included potassium permanganate, ammonium nitrate and instructions on how to make explosives ; and an atomic energy lab (# 1 ) which included uranium and radium samples and a coupon for ordering replacement uranium and radium through the mail.

Most were Jewish and several were from Budapest, and were instrumental in American scientific progress, for example developing the atomic bomb.

Most of the cold atomic hydrogen gas and the dust lies within this ring.

Most revision control systems support atomic commits ( CVS and VSS are the major exceptions ).

Most processors include store operations that are not atomic with respect to memory.

Most systems provide an atomic compare-and-swap instruction that reads from a memory location, compares the value with an " expected " one provided by the user, and writes out a " new " value if the two match, returning whether the update succeeded.

Most of its work was done with the strictest secrecy, and it began research of what would become some of the most important technology during World War II, including radar and the atomic bomb.

Most of the production is concentrated around components for nuclear power plants and atomic technology.

Most isotopic fractionations ( including typical kinetic fractionations and equilibrium fractionations ) are caused by the effects of the mass of an isotope on atomic or molecular velocities, diffusivities or bond strengths.

Most computer disk drives are not considered stable storage because they do not guarantee atomic write ; an error could be returned upon subsequent read of the disk where it was just written to in lieu of either the new or prior data.

Most of the isotopes with atomic mass numbers below 14 decay to isotopes of carbon, while most of the isotopes with masses above 15 decay to isotopes of oxygen.
