Since JSF is primarily component oriented, this is one of the core packages.

Since many components of natural foods have E numbers ( and the number simply is a synonym for the chemical component ), e. g. vitamin C ( E300 ) and lycopene ( E160d ), this is incorrect ; presumably the intent is that the ingredients list does not list any food additives by E number, that is, pure forms of the substances are not intentionally added.

Since World War II, this attitude in planning has resulted in the widespread use of travel modeling as a key component of regional transportation planning.

Since later television designs include composite, S-Video, and component video jacks, which skip the modulation and demodulation steps, modulators are no longer included as standard equipment, and RF modulators are now largely a third-party product, purchased primarily to run newer equipment such as DVD players with an old television set.

Since constitutional law cannot be altered by state legislatures, this direct democracy component gives the people an automatic superiority and sovereignty, over representative government ( Magelby, 1984 ).

Since the plane of the mirror in which one looks directly is beyond that of the other mirror, one always looks at an oblique angle, and the translation just mentioned has not only a component away from the observer, but also one in a perpendicular direction.

Since 2006, Cosworth has committed itself to engineering consultancy and component manufacture for an increasingly diverse customer base, including original equipment manufacturer ( OEM ) automotive, aerospace, defence and aftermarket sectors.

Since all Microsoft Office files are OLE 2 files, this component is the basic building block of all the other POI elements.

Since the human visual system is much more sensitive to variations in brightness than color, a video system can be optimized by devoting more bandwidth to the luma component ( usually denoted Y '), than to the color difference components Cb and Cr.

Since a SSEP can be completely described in terms of the amplitude and phase of each frequency component it can be quantified more unequivocally than an averaged transient evoked potential.

Since about 1950, a single four-terminal component containing the four diodes connected in a bridge configuration became a standard commercial component and is now available with various voltage and current ratings.

Since the 1990s, incoming students are required to participate in the TCNJ First Year Experience, a large component of the liberal arts curriculum at TCNJ.

Since February 15, 1974 the Thunderbirds have been a component of the 57th Wing at Nellis AFB.

Since Windows 2000 and FrontPage 2000, PWS was replaced by IIS as a standard Windows component.

Since such life utilised strong nuclear forces instead of electromagnetic interactions, it was posited that life might function millions of times faster than typical on Earth.

Since the nuclear pores are located in an area of high traffic, they play an important role in the physiology of cells.

Since 2002, the new Afghan government has engaged in cordial relations with both Iran and the United States, even as relations between Iran and the United States have grown strained due to American objections to Iran's nuclear program.

Since it can absorb nuclear fission-bred neutrons, it is also used in nuclear control rods.

Since the election of George W. Bush as the President of the United States, North Korea has faced renewed external pressure over its nuclear program, reducing the prospect of international economic assistance.

Since the late 1980s, North Korea's nuclear program has become a pressing issue in international affairs.

Since then, a very similar agreement was reached on February 13, 2007, that includes normalizing US-North Korean and Japanese-North Korean diplomatic ties on the condition that North Korea freeze its Yongbyon nuclear facility.

Since nuclear chain reactions only require natural materials ( such as water and uranium ), it is possible to have these chain reactions occur where there is the right combination of materials within the Earth's crust.

Since the probability per distance traveled for a neutron to collide with a nucleus is proportional to the material density, increasing the density of a fissile material can increase k. This concept is utilized in the implosion method for nuclear weapons.

Since 1960, the U. S. and Japan have maintained an agreement that allows the U. S. to secretly bring nuclear weapons into Japanese ports, and there is speculation ( see below ) that some nuclear weapons may be located in Okinawa.

Since the Soviets claimed to have first detected the new element they suggested the name kurchatovium, Ku, in honor of Igor Kurchatov ( 1903 – 1960 ), former head of Soviet nuclear research.

Since a nuclear explosion was used as the power source, the detector was destroyed during the experiment and the results therefore could not be confirmed.

Since its inception in 1948, the U. S. Navy nuclear program has developed 27 different plant designs, installed them in 210 nuclear powered ships, taken 500 reactor cores into operation, and accumulated over 5, 400 reactor years of operation and 128, 000, 000 miles safely steamed.

Since man-made sources accounted for only 18 % of the total radiation exposure, most of which came from natural sources ( 82 %), medical X-rays only accounted for 10 % of total American radiation exposure ; medical procedures as a whole ( including nuclear medicine ) accounted for 14 % of total radiation exposure.

Since uranium and plutonium are nuclear weapons materials, there have been proliferation concerns.

Since the U-235 content of nuclear reactor fuel is reduced by fission, uranium recovered by nuclear reprocessing from spent nuclear reactor fuel made from natural uranium will have a lower-than-natural U-235 concentration.
