Since a ruled surface of order N with N concurrent generators is necessarily a cone, it follows finally that every line through a point, P, of **zg meets its image at P, as asserted.

Since effective area coverage appears fairly remote, the requirement can be borne in mind while considering the elements: air, surface, sub-surface, fixed installations, mines, and intelligence.

Since less of its surface area is exposed to the arctic cold, less heat escapes the body.

Since water that flows through a cave eventually comes out in streams and rivers, any pollution may ultimately end up in someone's drinking water, and can even seriously affect the surface environment, as well.

Since the well-known technique of pattern welding produced surface patterns similar to those found on Damascus blades, some believe that Damascus blades were made using this technique.

Since part of this re-radiation is back towards the surface and the lower atmosphere, it results in an elevation of the average surface temperature above what it would be in the absence of the gases.

Since wave resistance and other impeding forces such as various types of drag ( physics ) on the hull are eliminated as the hull is lifted clear, turbulence and drag act only on the much smaller surface area of the hydrofoil and there is a marked increase in speed.

Since it is bearing surface that matters here, it is important that the bullets have a consistent bearing surface.

Since the deformations on the surface are the only imprint of the incoming particle, and since these deformations would have to completely determine the outgoing particles ,'t Hooft believed that the correct description of the black hole would be by some form of string theory.

Since air is plentiful at the surface of the earth, the oxidizer is typically atmospheric oxygen, which has the advantage of not being stored within the vehicle.

Since the actual physical surface of the Earth is too complex for mathematical analysis two levels of abstraction are employed in the definition of these coordinates.

Since there are many different reference ellipsoids the latitude of a feature on the surface is not unique: this is stressed in the ISO standard which states that " without the full specification of the coordinate reference system, coordinates ( that is latitude and longitude ) are ambiguous at best and meaningless at worst ".

Since the mid 1990s, thousands of surface scientists and thin film technocrats have latched on to the nanotechnology bandwagon and redefined their disciplines as nanotechnology.

Since the beginning of civilization, people have used stone, ceramics and, later, metals found on or close to the Earth's surface.

Since surface area is a geometric notion, areas of congruent surfaces must be the same and area must depend only on the shape of the surface, but not on its position and orientation in space.

Since then, wind and wave erosion have caused the island to steadily diminish in size: as of 2002, its surface area was.

Since some of the outward drift is compensated by an inward drift on the same flux surface, there is a macroscopic equilibrium with much improved confinement.

Since orbital energies are unique to an atom of a specific element, analysis of the ejected electrons can yield information about the chemical composition of a surface.

Since then, electric power has been used almost exclusively for powering submarines underwater, although diesel was used for powering them on the surface until the development of diesel-electric transmission by the US Navy in 1928.

Since that time, the rate of crater production on Earth has been considerably lower, but it is appreciable nonetheless ; Earth experiences from one to three impacts large enough to produce a 20 km diameter crater about once every million years on average.

Since the Earth could be expected to have roughly the same cratering rate as the Moon, it became clear that the Earth had suffered far more impacts than could be seen by counting evident craters.

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 tropical rainforests are the most diverse ecosystems on Earth and about 80 % of the world's known biodiversity could be found in tropical rainforests, removal or destruction of significant areas of forest cover has resulted in a degraded environment with reduced biodiversity.

Since 1988, the group has also hosted Earth Celebration, which brings artists and enthusiasts from all over the world to Sado Island.

Since this occurs only when the Moon is on the far side of the Earth from the Sun, lunar eclipses only occur when there is a full moon.

Since life began on Earth, several major mass extinctions have significantly exceeded the background extinction rate.

Since Fjorgyn is not only the name of a goddess, but the feminine byname for Earth, it is relatively safe to assume that " mær ", in this case, means " daughter ".

Since the original definition of the metre was one-quarter of one ten-millionth of the circumference of the Earth ( along the great circle coincident with the meridian of longitude passing through Paris ), the circumference of the Earth is about 40, 000 km or about 200, 000 furlongs.

Since there is no conclusive or certifiable evidence on Earth or elsewhere in the known universe of other intelligent life after 13. 7 billion years of the universe's history, we have the conflict requiring a resolution.

Since these people would have to be descended from Adam, they would have had to travel to the other side of the Earth at some point ; Augustine continues:

Since there is a very noticeable force of gravity acting between the Earth and any other nearby object, down is defined as that direction which an object moves in reference to the Earth when the object is allowed to fall freely.

Since the dawn of the Space Age, close observation by probes has found that Earth and the other planets share characteristics such as volcanism, hurricanes, tectonics, and even hydrology.

Since Alpha Centauri is the star system closest to Earth, it indicates that, in the altered timeline, the Romulans invaded Earth's stellar region, despite not even being prompted by Earth's role in the encouragement of interplanetary cooperation.

Since then, thousands of satellites have been launched into orbit around the Earth.

Since then, the normal modes of the Earth have given us some of the strongest constraints on the deep structure of the Earth.

Since human existence on Earth is said to be "

Since we see it nearly pole-on, its apparent luminosity from Earth is notably higher, about 57 times the Sun's value.

Since the space shuttle fleet has retired ( while Hubble still has many years of service life ahead ), there will be no existing or planned spacecraft capable of returning the Hubble to Earth intact, so it is now very unlikely it will ever be on the ground again.

Since the Supreme Court's decision of that year this is more doubtful ; ;

( Since the time-span of the nation-state coincides roughly with the separate existence of the United States as an independent entity, it is perhaps natural for Americans to think of the nation as representative of the highest form of order, something permanent and unchanging.

Since it is not far from Viareggio, he will visit Puccini's house, as he never fails to do, to pay his respects to the memory of the composer of La Boheme, which he considers one of Puccini's masterpieces.

Since attack serves to stimulate interest in broadcasts, I added to my opening statement a sentence in which I claimed that German youth seemed to lack the enthusiasm which is a necessary ingredient of anger, and might be classified as uninterested and bored rather than angry.

Since the air is a continuum, the network of communication remains intact regardless of the positions or motions of the points ( the people ) in the net.

Since the hazards of poor communication are so great, p can be justified as a habitable site only on the basis of unusual productivity such as is made available by a waterfall for milling purposes, a mine, or a sugar maple camp.

Since the difficulty of drawing the net is great, we will merely discuss it.

Since a civilizational crisis involves also a crisis in private interests and in the ruling class, reaction is normally found among those who feel themselves to be among the ruling class.

Since civilizational change is the most difficult to perceive and analyze, it seldom is given adequate attention.

Since the slogans have little application to reality and are sanctimonious to boot, the applause is faint even in areas of the world where we should expect to find the greatest affection for free government.

Since more is known about Quiney than about any other acquaintance of Shakespeare in Stratford, his career may be followed to its sudden end in 1602.

Since the great flood of these dystopias has appeared only in the last twelve years, it seems fairly reasonable to assume that the chief impetus was the 1949 publication of Nineteen Eighty-Four, an assumption which is supported by the frequent echoes of such details as Room 101, along with education by conditioning from Brave New World, a book to which science-fiction writers may well have returned with new interest after reading the more powerful Orwell dystopia.

Since Laos is of no more purely military value to Moscow itself than it is to Washington, this approach might be expected to head off Mr. Khrushchev for the moment.

Since little is known about autism, and almost nothing has been written for the layman, we'd like to share one experienced mother's comments.

Since the work is done by hand, the only limitation, it is said, `` is that of human conception ''.

Since the apparatus is new, it requires experimentation and changes in technique.

Since the obvious is not always true, the Republican National Committee wisely analyzed its defeat of last autumn and finds that it occurred, as suspected, in the larger cities.

Since he has just shown who is top dog, he may not be ready to receive this highest honor in the gift of the Soviet people.

Since appeals to morality, to humanity, and to sanity have had such small effect, perhaps our last recourse is the deterrent example.

Since the goal of our international planners is a World Government, this Atlantic Community would mark a giant step in that direction for, once American economic autonomy is absorbed, a larger grouping is a question of time.
