These measured positions are then compared with those calculated by the laws of celestial mechanics: an assembly of calculated positions is often referred to as an ephemeris, in which distances are commonly calculated in astronomical units.

These vast distances from the sea have had a profound impact on Chad's historical and contemporary development.

These higher speeds better serve the longer distances involved.

These ships generally provide the least expensive way to cover long distances between islands.

# These objects could have had their orbits and perihelion distances " lifted " by the passage of a nearby star when the Sun was still embedded in its birth star cluster.

These luminous stars can be detected at great distances, and are then used to extend the distance scale to nearby galaxies in the Local Group.

These distances determined the traditional size of the strips: a furlong, ( or " furrow's length ", ) by a chain () – an area of one acre ( about 0. 4 hectares ); this is the origin of the acre.

These forces were capable of moving long distances in short times, allowing a quick return home after sacking a target.

These wires pass through holes drilled in the blades at suitable distances from the blade root and are usually brazed to the blades at the point where they pass through.

These distances combined geometrically with precise orbital information identify the location of the receiver.

These tombs, which date to the Early Dynastic IIIa period ( approximately in the 25th or 24th century BC ), contained immense amounts of luxury items made out of precious metals, and semi-precious stones all of which would have had to been imported from long distances ( Iran, Afghanistan, India, Asia Minor, the Persian Gulf ).

These facts made it impractical to use Preece's system on either ships, boats, or ordinary islands ( ones much smaller than Great Britain or Greenland ), and the relatively short distances that a practical Preece system could span meant that it had few advantages over underwater telegraph cables.

These results were confirmed by Grocholski et al., who calculated distances to a number of clusters and showed that the LMC's cluster system is in fact distributed in the same plane as the field stars.

These are pairs of parallel channels cut into the surface of the rock, and extending for considerable distances, often in an exactly straight line.

These wider, dead, empty cells were a million times more conductive than the inter-cell method, giving the potential for transport over longer distances, and higher diffusion rates.

These are something of a Finnish cultural tradition ( see ruotsinlaiva ), and people often travel long distances across Finland to Turku just to take a cruise across the Gulf of Bothnia.

These are located mainly in Sogn og Fjordane and Northern Norway, in areas with long distances to large cities and with too little traffic to support commercial flights.

These transformations displace the triangle in the plane without changing the angle at each vertex or the distances between vertices.

These events have their roots in races of imperial measurements which were later altered to metric: the 100 m evolved from the 100 yard dash, the 200 m distances came from the furlong ( or 1 / 8 of a mile ), and the 400 m was the successor to the 440 yard dash or quarter-mile race.

These are straight line distances to cities, seas that wash the Spanish coast and the frontier with Portugal, France and Andorra:

These night trains are a prime method of travel, with ticket prices quite reasonable by Western standards, and with the distances between the capitals of Moscow and Kiev and many outlying cities being ideal for overnight trips that depart in late evening and arrive at their destinations in the morning.

These distances are still law in England today.

These actions are complicated by the fact that only Ico is able to carry out these actions ; Yorda can only jump short distances and cannot climb over tall barriers.

These methodologies use a set of known information, usually distances or target sizes, to make the measurement, and have been in regular use since the 18th century.

These high trophic oceanodromous species undertake migrations of significant but variable distances across oceans for feeding, often on forage fish, or reproduction, and also have wide geographic distributions.

These seem about the only two ways in which the `` unhappy incident '' can now be closed.

These engines can be removed from a boat with relative ease, wherein lies their greatest advantage.

These can also move a short distance but at right angles to the tappets.

These are beginnings, but correctly learned they prepare for satisfying and exciting stunts that can be performed by a strong, flexible body ( we are not talking of eccentric extremes ).

These frequencies are amplified and detected by the FM receiver after each burst of transmitted energy and, after the `` pill '' has been calibrated, precise internal pressure indications can be obtained.

These factors can make the difference between waste and efficiency in any benefit program.

These experiments can be considered exploratory only.

These societies can expect to face difficult times.

These records, when systematically maintained, provide much information about the children, which the teacher can use in guidance, instruction, grouping, and reporting to parents.

These can be referred to as operational intelligence and environmental intelligence.

These theoretical relationships are more clearly illustrated in Fig. 7 and their sum can be seen to correlate in form with practical measurements made with the Hesiometer as illustrated in the first portion of Fig. 5 for the cutting mechanism.

These dynamic relationships, between what can be observed on the ground, as opposed to what can be observed by compiling many local observations remain fundamental in any kind of anthropology, whether cultural, biological, linguistic or archaeological.

These are not used in amoeboid movement, but are stiff skeletons on which organelles are supported or can move on.

These can range from simple spelling changes and word forms to switching the entire writing system itself, as when Turkey switched from the Arabic alphabet to a Turkish alphabet of Latin origin.

These finishes protect the adobe wall from water damage, but need to be reapplied periodically, or the walls can be finished with other nontraditional plasters providing longer protection.

These deficits can vary depending on which cerebellar structures have been damaged, and whether the lesion is bilateral or unilateral.

These include all quadratic surds, all rational numbers, and all numbers that can be formed from these using the basic arithmetic operations and the extraction of square roots.

These frequencies can be used to study geological phenomena such as earthquakes.

These are naturally in a ground state but can be excited

These constructions can convey shape, size, motion, location, movement, stative-descriptive, and / or handling information.

These particles continue to decay, emitting alpha particles which can damage cells in the lung tissue.

These conditions can be used to handle unusual situations.

These antigens can sometimes be presented by tumor cells and never by the normal ones.

These can be as simple as a searchlight for a police helicopter or as complicated as the tactical system for an airborne early warning platform.
