Hammer and Anvil Technique
The hammer and anvil technique for removing flakes from a core is perhaps one of the oldest documented methods. It is quite effective for making large flakes for direct use as tools, or for use as blanks from which shaped tools can be made. This technique entails using the core as a hammer, and striking the edge of the core against a large, stationary rock (the anvil) in order to remove a flake.
Bipolar Technique
The bipolar technique is a modification of the hammer and anvil technique. In bipolar flaking, the core is placed on the anvil for support, and then struck with a large heavy hammer. The compression from both ends of the core cause it to shatter into hundreds of flakes, some of which will be large enough, and of the right shape for use as tools. This technique is often found in areas where the only reliable source of workable stone is rounded river cobbles that are extremely hard to work in any other fashion.
The Romans captured Brittani(Wales), Hispania(spain),Gaul(France), Achaea(greece),Judea, and northern Africa. The Roman empire was soon conquered by tribes (or barbarians.) Hope this helps!!! :)
Among the other achievements of Reconstruction were the South's first state-funded public school systems, more equitable taxation legislation, laws against racial discrimination in public transport and accommodations and ambitious economic development programs (including aid to railroads and other enterprises).
<span>By demanding that a dispute between Venezuela and Great Britain be sent to arbitration, the United States defended the validity of the Monroe Doctrine. (Arbitration is the settlement of a dispute by a person or panel chosen to listen to both sides and come to a decision.) The British government backed down because it needed to stay on friendly terms with the United States.<span>The United States became involved in the Cuban rebellion against Spain, to protect American business interests. </span></span>
Hope this helps!
