  Central African Republic - Wikipedia, the free encyclopedia
European penetration of Central African territory began in the late nineteenth century during the Scramble for Africa (c.
When news of terrible atrocities committed against Central Africans by concessionary company employees and colonial officials or troops reached France and caused an outcry, there were investigations and some feeble attempts at reform, but the situation on the ground in Ubangi-Shari remained essentially the same.
New forms of forced labor were also introduced, however, as the French conscripted large numbers of Ubangians to work on the Congo-Ocean railway and many of these recruits died of exhaustion and illness.

 Key Ideas: Central Net Force Model   (Site not responding. Last check: 2007-10-19)
The net force needed to curve an object away from straight line motion is directly proportional to the object's mass, directly proportional to the square of the object's velocity and inversely proportional to the radius of the object's path.
Centripetal force is the name for the "net force toward the center of the circle" that causes circular motion to occur.
Centrifugal force is the name for the apparent force that "pushes" objects away from the center of a circle from the viewpoint of the object that is undergoing circular motion.

 IREX - International Research & Exchanges Board > Publications > Islam as a Political Force in Central Asia   (Site not responding. Last check: 2007-10-19)
Fear among leaders in Central Asia about the emergence of radical Islamic movements in the region has been used to deny human rights, ban nonofficial Islamic-based political groups, and even outlaw long beards, which are seen as an outward sign of fundamentalist beliefs.
Iran’s ability to influence the Islamic revival in Central Asia was hindered by its historical-cultural divide with the area and the post-Soviet geopolitics of the region.
Central Asia is moving consistently toward authoritarian practices, but Iran is on a more positive and progressive track, with Iran’s clerical leadership under popular pressure to become more liberal socially and politically.

 External Force Analysis
The external force analyses of the strategic planning process were organized in three task forces, the economic and technological dimensions; the political, legal, and competitive dimensions; and the social, cultural, and demographic dimensions.
In selecting the members of the three task forces, effort was made to have a wide representation of faculty and staff from the academic and administrative sides of the University.
The names of the task force members and the original forces are all documented in a later section of this document.

 Centripetal Force
Magnetism is a source of a non-mechanical force that results in charged particles traveling in circular paths.
It is supplying the centripetal force necessary to keep the block moving as a conical pendulum.
For a satellite in circular orbit, the unbalanced central force is supplied by gravity.

 [No title]   (Site not responding. Last check: 2007-10-19)
If the force F is very strong, then the object may spiral inwards towards the location of F. If the force is weak (or tails off with distance) then the object may deflect only slightly from its original path.
This force causes the planets to move around the sun in orbits that are almost circular (they are actually elliptical, but the mathematics is very similar to that of circular orbits).
Because the centripetal force is inversely proportional to the turning radius, the force decreases as the radius increases, so we will reach a point where the increasing radius balances our increase in speed, and the tyres can once again provide enough grip to keep the car moving in a circle.

The period is measured with a photogate and the centripetal force is measured with a force probe.
It is important to line the force probe up with the center of the fan to reduce variations in the force measurements.

The Southern Forces under Nishimura and Shima were to rendezvous in the Sulu Sea and attack Leyte Gulf from the south (in a coordinated "pincer" maneuver with the Central Force) by way of the Mindanao Sea and Surigao Strait.
Finally, the Northern Force was to sail south (from Japan) toward Luzon and lure the American Third Fleet away from the Leyte beachhead, clearing the way for the Central and Southern forces.
The bulk of the fleet's heavy units, comprising the Central Force and the van of the Southern Force, was based in Lingga Anchorage near Singapore (close to their fuel sources).

 United Nations approves multinational force in central Zaire   (Site not responding. Last check: 2007-10-19)
UNITED NATIONS (AP) - The U.N. Security Council unanimously approved a multinational force to aid a million refugees in central Africa, despite Rwanda's claims Friday that troops are unnecessary because the refugees have begun returning home.
About 4,000 U.S. troops are expected to participate in the international force, and President Clinton on Friday announced preparations for the deployment of U.S. forces.
Despite the heartening news that up to a third of the Rwandan refugees in Zaire may finally be going home, people will continue to die in eastern Zaire in appalling numbers and their presence there will continue to destabilize the region,'' he said.

The force of attraction due to gravity is shown in the blue arrows and the relative kinetic energies are shown as a function of time in the graph (note that for this simulation the unit for the kinetic energy is not given as we are just comparing the relative amount for each object).
Also note that the eccentricity of the orbit e = 0.048, the perihelion and aphelion distances, and the planet's period, match that of Jupiter.
But at every instant, the forces of gravitational attraction (the force of the blue circle due to the orange circle and the force of the orange circle due to the blue circle) are always the same.
