As kinetochore microtubules from both centrioles attach to their respective kinetochores, the homologous chromosomes align along an equatorial plane that bisects the spindle, due to continuous counterbalancing forces exerted on the bivalents by the microtubules emanating from the two kinetochores of homologous chromosomes.

They also generate the forces exerted by contracting muscles.

The orbit of a planet around the Sun is not really an ellipse but a flower-petal shape because the major axis of each planet's elliptical orbit also precesses within its orbital plane, partly in response to perturbations in the form of the changing gravitational forces exerted by other planets.

An engineering application of this concept is determining the tensions of up to three cables under load, for example the forces exerted on each cable of a hoist lifting an object or of guy wires restraining a hot air balloon to the ground.

Through the magnetic forces that this system achieves, a force is exerted on the projectile moving it down the rail.

* Terminal velocity in physics, the speed of an object when the restraining force exerted by a fluid ( such as air ) is equal to other forces ( such as gravity ) ( see also Terminal velocity ( disambiguation ))

The topographic height of orogenic mountains is related to the principle of isostasy, that is, a balance of the downward gravitational force upon an upthrust mountain range ( composed of light, continental crust material ) and the buoyant upward forces exerted by the dense underlying mantle.

Organizations in nearly every industry face the above competitive forces exerted by suppliers, customers, rivals, potential new entrants, complementors, and substitute products.

In particular, the short average distances between molecules raises the intensity of intermolecular forces between gas molecules enough to substantially change the pressure exerted by them.

To distribute the compressive forces exerted on the heel during gait, and especially the stance phase when the heel contacts the ground, the sole of the foot is covered by a layer of subcutaneous connective tissue up to 2 cm thick ( under the heel ).

Because of the large forces which are exerted on the rock when an SLCD is fallen on, it is very important that SLCDs are only placed in solid, strong rock.

Throughout the course of the fictional limiting quasi-static process, the internal intensive variables of the system are equal to the external intensive variables, those which describe the reactive forces exerted by the surroundings.

He contributed to the calculation of the forces exerted by moving engines on bridges.

If the vehicle does not have adequate wheel location in the vertical plane ( such as a rear-wheel drive car with Hotchkiss drive, a live axle supported by simple leaf springs ), vertical forces exerted by acceleration or hard braking combined with high unsprung mass can lead to severe wheel hop, compromising traction and steering control.

The total work done in a given time interval by the forces exerted by two bodies on each other is the same as the work done by one force applied to the total relative displacement.

The country sank even further into anomie, forces loyal to Rabbani and Masud, both ethnic Tajiks, controlled Kabul and much of the northeast, while local warlords exerted power over the rest of the country.

Haptic devices may incorporate tactile sensors that measure forces exerted by the user on the interface.

The tie is capable of withstanding the horizontal thrust forces which would normally be exerted on the abutments of an arch bridge.

Tidal power is extracted from the Earth's oceanic tides ; tidal forces are periodic variations in gravitational attraction exerted by celestial bodies.

The deployment of a portion of these forces beyond our shores, on land and sea, is persuasive demonstration of our determination to stand shoulder-to-shoulder with our allies for collective security.

To help him do so The Prince had conferred control of his land forces on a soldier who was different from him in almost every respect save one: both were eccentrics of the purest ray serene.

The results of the study, based on collision integrals computed from the latest critically evaluated data on intermolecular forces in air, will be reported in the form of a table of viscosity, thermal conductivity, thermal diffusion, and diffusion coefficients at temperatures of 1,000 to 10,000 Af and of logarithm of pressure in atmospheres from Af to Af times normal density.

The total adverse impact of disease, insects, fire, weather, destructive animals, and other forces on the uses and values of forest resources is not generally recognized.

The relative forces can be calculated from the various radii of curvature if we assume: ( A ) The surface tension is uniform on the surface of the drop.

In order to focus clearly upon the operation of this one force, which we may call the effect of `` public-limit pricing '' on `` key '' wage bargains, we deliberately simplify the model by abstracting from other forces, such as union power, which may be relevant in an actual situation.

For example Test 3, E 1 refers to a specimen which has been washed by procedure `` 3 ( '' ( at 160-degrees-F ) for a total of 60 minutes in the machine, has been dried in a tumble dryer by procedure `` E '' and has been subjected to restorative forces on the Tension Presser by procedure `` 1 ''.

Active warfare is raging between the forces pressing for a monument to the first Roosevelt on Theodore Roosevelt Island in the Potomac, and TR.'s own living children, who wish to preserve the island as a wildlife sanctuary.

He suggested that a regrouping of forces might allow the average voter a better pull at the right lever for him on election day.

The panel's action depends on the return of Representative James W. Trimble, Democrat of Arkansas, who has been siding with Speaker Sam Rayburn's forces in the Rules Committee in moving bills to the floor.

Ideally, the President would like the French to agree on a `` status quo ante '' on Bizerte, and accept a new timetable for withdrawing their forces from the Mediterranean base.

After this time, inscriptions on the Han bronze mirrors, as well as other writings, emphasized the desirability of keeping one's self at the center of the universe, where cosmic forces were strongest.

On the whole, however, one must wonder at just what it is that forces a beloved artist to besmirch her own reputation as time marches inexorably on.

On April 12, 1861, Confederate forces fired on Union troops at Fort Sumter, forcing them to surrender, and began the war.

Even though they had the advantage of fighting on the defensive, the Confederate forces had " almost as high a percentage of casualties as the Union forces ".

Johnston, who had little choice in allowing Floyd and Pillow to take charge at Fort Donelson on the basis of seniority after he ordered them to add their forces to the garrison, took the blame and suffered calls for his removal because a full explanation to the press and public would have exposed the weakness of the Confederate position.

Gen. Buell on February 25, 1862, two days after Johnston had to pull his forces out in order to avoid having them captured as well.

Bragg at least calmed the nerves of Beauregard and Polk who had become agitated by their apparent dire situation in the face of numerically superior forces before the arrival of Johnston on March 24, 1862.

Johnston now planned to defeat the Union forces piecemeal before the various Union units in Kentucky and Tennessee under Grant with 40, 000 men at nearby Pittsburg Landing, Tennessee, and the now Maj. Gen. Don Carlos Buell on his way from Nashville with 35, 000 men, could unite against him.

Johnston launched a massive surprise attack with his concentrated forces against Grant at the Battle of Shiloh on April 6, 1862.

As the Confederate forces overran the Union camps, Johnston seemed to be everywhere, personally leading and rallying troops up and down the line on his horse.

The position of the Arctic Circle is not fixed, but directly depends on the Earth's axial tilt, which fluctuates within a margin of 2 ° over a 40, 000 year period, notably due to tidal forces resulting from the orbit of the Moon.
