Non-hereditary causes of cerebellar degeneration include chronic ethanol abuse, paraneoplastic cerebellar degeneration, high altitude cerebral oedema, coeliac disease, normal pressure hydrocephalus and cerebellitis.

Phoenix uses its high altitude to gain gravitational potential energy, which is later converted into kinetic energy as the missile dives at high velocity towards its target.

High speed and high altitude flying became a means of evading detection and attack.

When surface to air missiles became capable of hitting high flying aircraft bombers, bombers used flight at low altitude to evade radar detection.

Once " stand off " nuclear weapon designs were developed, bombers did not need to pass over the target at high altitude to make an attack ; they could fire and turn away to escape the blast.

However, the relatively high altitude of the country and its continental situation gives it a subtropical climate.

This new design was licensed by the British, who produced ball point pens for RAF aircrew as the Biro ; they found they worked much better than fountain pens at high altitude, the latter being prone to ink-leakage in the decreased atmospheric pressure.

Modern cruise missiles can travel at supersonic or high subsonic speeds, are self-navigating, and can fly on a non-ballistic, extremely low altitude trajectory.

Ebor is at fairly high altitude, about 1, 300 metres and by Australian standards, has cold winters with overnight frost and occasional light snow falls.

Temperate needleleaf forests mostly occupy the higher latitude regions of the northern hemisphere, as well as high altitude zones and some warm temperate areas, especially on nutrient-poor or otherwise unfavourable soils.

Singer said that the firings placed " the exploration of outer space with high altitude rockets on the same basis, cost-wise and effort-wise, as low atmosphere measurements with weather balloons.

Gemini established that radiation at high altitude was not a problem.

A total of 8 had been launched ; one missile hit a MiG-19 jet fighter sent to intercept the U-2, but which was unable to reach a high enough altitude.

Generalized hypoxia occurs in healthy people when they ascend to high altitude, where it causes altitude sickness leading to potentially fatal complications: high altitude pulmonary edema ( HAPE ) and high altitude cerebral edema ( HACE ).

Sometimes, on a return trip, the aviator would `` go upstairs '' high over the clouds.

An afterglow may appear above the highest clouds in the hour of deepening twilight, or reflected from the high snowfields in mountain regions long after sunset.

Hail forms in strong thunderstorm clouds, particularly those with intense updrafts, high liquid water content, great vertical extent, large water droplets, and where a good portion of the cloud layer is below freezing.

These were diffuse filamentary clouds that are visible at high galactic latitudes ( looking out of the plane of the galactic disc ).

Its relative rarity on Earth, like that of helium, is due to its relative lightness, high vapor pressure at very low temperatures, and chemical inertness, all properties which tend to keep it from being trapped in the condensing gas and dust clouds which resulted in the formation of smaller and warmer solid planets like Earth.

With the Intertropical Convergence Zone ( ITCZ ) swinging northward over West Africa from the Southern Hemisphere in April, heavy showers coming from pre-monsoonal convective clouds mainly in the form of squall lines also known as the north easterlies formed mainly as a result of the interactions of the two dominant airmasses in Nigeria known as the Maritime tropical ( south westerlies ) and the Continental tropical ( north easterlies ), begins in central Nigeria while the Monsoons from the south atlantic ocean arrives in central Nigeria in July bringing with it high humidity, heavy cloud cover and heavy rainfall which can be daily occurrence lasting till September when the monsoons gradually begin retreating southward to the southern part of Nigeria. Rainfall totals in central Nigeria varies from in the lowlands of the river Niger Benue trough to over along the south western escarpment of the Jos Plateau.

The particles were never observed to rise above 6 km and when combined with scavenging by clouds gave the smoke a short residency time in the atmosphere and localized its effects ; Professor Carl Sagan of the Turco, Toon, Ackerman, Pollack, Sagan ( TTAPS ) study hypothesized in January 1991 that enough smoke from the fires " might get so high as to disrupt agriculture in much of South Asia ...." Sagan later conceded in his book The Demon-Haunted World that this prediction did not turn out to be correct: " it was pitch black at noon and temperatures dropped 4 °– 6 ° C over the Persian Gulf, but not much smoke reached stratospheric altitudes and Asia was spared.

When the air reaches a high altitude, where the temperature is low, water vapor condenses into clouds, which rain onto the Earth's surface, completing the water cycle.

Molecular clouds may collide with each other, or a nearby supernova explosion can be a trigger, sending shocked matter into the cloud at very high speeds.

Cirrus clouds are formed when water vapor undergoes deposition at high altitudes where the atmospheric pressure ranges from 600 mbar at above sea level to 200 mbar at above sea level.

Because humidity is low at such high altitudes, these clouds tend to be very thin.

The other two genera, cirrocumulus and cirrostratus, are also high clouds.

They comprise the genera cumulus, and cumulonimbus, which along with nimbostratus, are often classified separately as clouds of vertical development, especially when their tops are high enough to be composed of super-cooled water droplets or ice crystals.

There are three main genera in the family of high clouds: cirrus, cirrocumulus, and cirrostratus.

Cirrocumulus in its pure form is actually a high cumuliform genus, and cirrostratus is stratiform, like altostratus and lower based sheet clouds.

Low, thick clouds ( such as stratocumulus ) primarily reflect incoming solar radiation, causing it to have a high albedo, whereas high, thin clouds ( such as Cirrus ) tend to transmit it to the surface but then trap outgoing infrared radiation, causing it to have low albedo.

Prefixes are used in connection with clouds: strato-for low clouds with limited convection that form mostly in layers, nimbo-for thick layered clouds that can produce moderate to heavy precipitation, alto-for middle clouds, and cirro-for high clouds.

Cirriform-category clouds form at high tropospheric altitudes along the very leading edges of a frontal or low-pressure weather disturbance and often along the fringes of its other borders.

The best approach, he figured, was to try to influence young people like the high schoolers he and his wife serve as advisors at First Presbyterian Church.

There were no depressingly serious cases: the ward doctor sometimes teamed up with the chaplain to serve as a marriage counselor -- sometimes the Navy sent people back to the States to preserve a marriage -- but mental health as a rule was very high.

In these areas, the local telephone carriers are allowed to charge a high " termination fee " to the caller's carrier in order to fund the cost of providing service to the small and sparsely populated areas that they serve.

Nonetheless, a badminton court will not be suitable if the ceiling is likely to be hit on a high serve.

At high levels of play, the backhand serve has become popular to the extent that forehand serves have become fairly rare at a high level of play.

In singles, players will often start the rally with a forehand high serve or with a flick serve.

In middle school, the squads serve mostly the same functions as high school squads and follow the same rules and regulations.

Carson High School and the alternative Pioneer High School serve high school students.

The Hittites are usually depicted as a people living among the Israelites — Abraham purchases the Patriarchal burial-plot of Machpelah from " Ephron HaChiti ", Ephron the Hittite, and Hittites serve as high military officers in David's army.

Intensive or flexible therapy involves supplying a continual supply of insulin to serve as the basal insulin, supplying meal insulin in doses proportional to nutritional load of the meals, and supplying extra insulin when needed to correct high glucose levels.

Other mounds, known as rim craters, can be as high as 1 m. Dome craters and rim craters serve as observation posts used by the animals to watch out for predators.

After Christophorus ’ fall, Paulus Afiarta continued to serve the papal court in a high capacity.

First, it was necessary to obtain the divine will of the gods respecting his appointment by means of the auspices, since the king would serve as high priest of Rome.

On the other hand, rockets serve in many short-range relatively low speed military applications where their low-speed inefficiency is outweighed by their extremely high thrust and hence high accelerations.

During the daytime, he usually sits on a high perch, usually 3 – 5 feet off the ground to serve as a lookout for his flock.

This process is known as summation, and can serve as a high pass filter for neurons.

* Sky ball serve: a specific type of underhand serve occasionally used in beach volleyball, where the ball is hit so high it comes down almost in a straight line.

* Topspin: an overhand serve where the player tosses the ball high and hits it with a wrist span, giving it topspin which causes it to drop faster than it would otherwise and helps maintain a straight flight path.

* Jump serve: an overhand serve where the ball is first tossed high in the air, then the player makes a timed approach and jumps to make contact with the ball, hitting it with much pace and topspin.

* Jump float: an overhand serve where the ball is tossed high enough that the player may jump before hitting it similarly to a standing float serve.
