Orbital simulations are used to determine what orbital parameters (including orbital distance) produce the observations seen by astronomers.

Space stations typically require a regular altitude boost to counteract orbital decay (see also orbital station keeping).

They therefore have approximately the same orbital period as Neptune and follow roughly the same orbital path.

(iii) Any change of orbital position

A VECSEL is a vertical cavity, and is composed of two mirrors.

Normally the internal body cavity is lined with cotton wool or an appropriate material, the organs are then placed into a plastic bag to prevent leakage and returned to the body cavity.

Pneumoperitoneum is the presence of air or gas in the abdominal (peritoneal) cavity.

However, perturbations cause the orbital elements to change over time.

It would have an orbital period of roughly 1.8 million years.

The eastern rock nuthatch builds a similar but less complex structure across the entrance to a cavity.

These are the squamous part, the orbital part, and the nasal part.

In contrast, molecular orbital theory has orbitals that cover the whole molecule.

STS 1 was the first orbital flight of NASA's Space Shuttle program.

(d) Other legal matters 1, including legal aspects of sub orbital flights.

The nasal cavity is unique, as the only place where brain cells (neurons) are directly exposed to the environment.

The sinus cavity is lined with a membrane called the Sniderian membrane, which may or may not be perforated.

(iii) Kilometres, minutes and degrees as the standard units for basic orbital parameters

Damage caused by the anthrax spores and bacilli to the central chest cavity can cause chest pain and difficulty breathing.

It is a measure of the actual degree of cleanliness of the orbital zone.

A random laser uses no optical cavity but the remaining principles of operation remain the same as for a conventional laser.

But I think when you guys start buying tickets and flying sub orbital flights to space, very soon wait a minute, what's happening here, we'll have military fighters with sub orbital capability, and I think very soon this.

The required speed is called orbital velocity, and it varies with the height of the orbit.

This includes Pluto, which shares its orbital neighbourhood with Kuiper belt objects such as the plutinos.

The light from the high power IR laser diodes is converted into visible light by means of extra cavity waveguided second harmonic generation.

ORT4 the tumor is affecting different areas outside of the hypopharynx, starting with the throat and moving towards the spine and chest cavity.

He guessed the same force was responsible for other orbital motions, and hence named it universal gravitation .

The presence of Neptune has a profound effect on the Kuiper belt's structure due to orbital resonances.

If Λ 1, then the body will likely clear out the small bodies in its orbital zone.

In that case, the observing campaign should at least achieve an orbital accuracy allowing a future recovery.

The Russian Federation has established world records in the length of a human's stay aboard an orbital station and has developed, in the course of operating the Mir orbital complex, effective technologies for medico biological support during prolonged stays in outer space.

Among the inter cavity doubled lasers VCSELs have shown much promise and potential to be the basis for a mass produced frequency doubled laser.

The first satellite (orbital) photographs of Earth were made on August 14, 1959 by the U.S. Explorer 6.

In perfect two body motion, these orbital elements would be invariant (just like the Keplerian elements would be).

The effects of orbital debris on space security and the urgent need for action were a major focus.

In 2008, there were 22,900 cases of oral cavity cancer, 12,250 cases of laryngeal cancer, and 12,410 cases of pharyngeal cancer in the United States.

To improve the energy transfer the beams are sent though the main amplifier section four times, using an optical switch located in a mirrored cavity.

The square of a satellite's orbital period is proportional to the cube of its average distance from the planet.

Earth co orbits with 10,000 near Earth asteroids (NEAs), and Jupiter has 100,000 Trojan asteroids in its orbital path.

The United States supported the IADC orbital debris mitigation guidelines, and its agencies were well along in implementing them.

Accelerating a spacecraft to orbital speed requires more than 60 times as much energy as accelerating it to Mach 3.

Despite the widespread acknowledgement of the danger of orbital debris, Aldworth emphasized that the problem has not deserved sufficient attention.

(a) To promote and coordinate at an international level activities related to the discovery, tracking and orbital computations of NEOs

The orbital elements given here are as of January 2000, but they are continuously changing due to solar and planetary perturbations.

(a) To promote and coordinate activities for the discovery, pursuit (follow up) and orbital calculation of NEOs at the international level

We brought patients in, six to eight weeks prior to their scheduled surgery, did X rays, and we then composed a scaffold specifically for that patient's size pelvic cavity.
