For the Bandanese, on the other hand, although they welcomed another competitor purchaser for their spices, the items of trade offered by the Dutch — heavy woollens, and damasks, unwanted manufactured goods, for example — were usually unsuitable in comparison to traditional trade products.

For this reason, the history of Cairo during Ottoman times is often described as inconsequential, especially in comparison to other time periods.

For example, Darwinism may be used to refer to Darwin's proposed mechanism of natural selection, in comparison to more recent mechanisms such as genetic drift and gene flow.

For comparison, the average was 73. 3 days in Latin America and 16. 3 days in OECD countries.

For comparison, the other two general conic sections, the ellipse and the parabola, derive from the corresponding Greek words for " deficient " and " comparable "; these terms may refer to the eccentricity of these curves, which is greater than one ( hyperbola ), less than one ( ellipse ) and exactly one ( parabola ), respectively.

For comparison, the most efficient small four-stroke motors are around 43 % thermal efficiency ( SAE 900648 ); size is an advantage for efficiency due to the increase in the ratio of volume to surface area.

For comparison, consider a similar example written in Java-based pseudocode:

For comparison, a capacitor stores energy in an electric field, and a resistor does not store energy but rather dissipates energy as heat.

For comparison, cooking, smoking, salting etc.

For comparison, milk heat pasteurization is not being alleged to be a method " to cover up poor food quality "; consequently, food irradiation should not be accused to serve such criminal purposes.

For comparison, woven garments stretch mainly along one direction ( the bias ) and are not very elastic, unless they are woven from stretchable material such as spandex.

( For comparison, a sphere is an orientable surface with no boundary.

For instance it is the most common way to transfer satellites into geostationary orbit, after first being " parked " in low earth orbit.

For example, for ground stations at latitudes of φ = ± 45 ° on the same meridian as the satellite, the time taken for a signal to pass from Earth to the satellite and back again can be computed using the cosine rule, given the geostationary orbital radius r ( derived below ), the Earth's radius R and the speed of light c, as

For synchronous satellites orbiting Earth, this is also known as a geostationary orbit.

For areas close to the North ( and South ) Pole, a geostationary satellite may appear below the horizon.

For the geostationary transfer orbit we have

For geostationary spacecraft the inclination change caused by the gravitational forces of Sun / Moon must be counteracted to a rather large expense of fuel as the inclination should be kept sufficiently small for the spacecraft to be tracked by a non-steerable antenna.

For geostationary spacecraft the eccentricity must be kept sufficiently small for a spacecraft to be tracked with a non-steerable antenna.

For geostationary spacecraft thruster burns orthogonal to the orbital plane must be executed to compensate for the effect of the lunar / solar gravitation that perturbs the orbit pole with typically 0. 85 degrees per year.

For satellites in geostationary orbit and geosynchronous orbits, the graveyard orbit is a few hundred kilometers above the operational orbit.

For many of the satellites, it is assumed that the rotation rate is equal to the mean orbital period.

For satellites having a mass less than M μ < sub > err </ sub >/ μ ≈ 10 < sup > 15 </ sup > kg, that is, over a billion times that of the ISS, the error due to the approximation is smaller than the error on the universal geocentric gravitational constant ( and thus negligible ).

For natural satellites, which can attain a synchronous orbit only by tidally locking their parent body, it always goes in hand with synchronous rotation of the satellite.

For fixed ( point-to-point ) services, communications satellites provide a microwave radio relay technology complementary to that of communication cables.

For this reason, if Venus's slow rotation rate began early in its history, any satellites larger than a few kilometres in size would likely have spiralled into the planet.

For example, the Miura map fold is a rigid fold that has been used to deploy large solar panel arrays for space satellites.

For Ku satellites in DBS ( Direct Broadcast Satellite ) service ( 12. 2-12. 7GHz in the U. S .) dishes much smaller than 1-meter can be used because those satellites are spaced 9 degrees apart.

For satellite communications, the microwave frequencies of the C-band perform better under adverse weather conditions in comparison with K < sub > u </ sub > band ( 11. 2 GHz to 14. 5 GHz ) microwave frequencies, which are used by another large set of communication satellites.

Kate Martin, of the Center For National Security Studies said of the use of military spy satellites being used to monitor the activities of U. S. citizens: " They are laying the bricks one at a time for a police state.

For earth-orbiting satellites, the reference plane is usually the Earth's equatorial plane, and for satellites in solar orbits it is the plane of the ecliptic | ecliptic plane.

For example, the levels of ionizing radiation and radio interference can vary by factors of hundreds to thousands ; and the shape and location of the magnetopause and bow shock wave upstream of it can change by several Earth radii, exposing geosynchronous satellites to the direct solar wind.

For scientific uses, a modern planetary ephemeris comprises software that generates positions of the planets and often of their satellites, or of asteroids or comets at virtually any time desired by the user.

For example, the 1995 declaration cites " observations from earth satellites ," where the 1997 declaration cites " observations from both weather satellites and balloon-borne radiosondes.

For the return signal, ground stations and satellites use a radio signal in the 894 to 896 megahertz range.

For information delivery to end-users, satellite systems, by nature, have relatively long path lengths, even for low earth-orbiting satellites.

For example, astronauts return from missions slightly younger than they would have been if they had remained on Earth, and Global Positioning System | GPS satellites work because they adjust for similar bending of spacetime to coordinate with systems on earth.

For reception of signals from several adjacent satellites, a larger non-parabolic multi-satellite dish ( such as the Simulsat ) that can see up to 3 or more satellites is often used.

For instance, Canada was a founding member of NATO, and was instrumental in the forming of that military alliance against the Soviet Union and its satellites.

Gardner holds up a " For Sale " sign, referring to the Palapa B-2 and Westar 6 satellites.
