While this process moved along, diplomacy continued its rounds. Direct pressure on the Taliban had proved unsuccessful. As one NSC staff note put it, "Under the Taliban, Afghanistan is not so much a state sponsor of terrorism as it is a state sponsored by terrorists." In early 2000, the United States began a high-level effort to persuade Pakistan to use its influence over the Taliban. In January 2000, Assistant Secretary of State Karl Inderfurth and the State Department's counterterrorism coordinator, Michael Sheehan, met with General Musharraf in Islamabad, dangling before him the possibility of a presidential visit in March as a reward for Pakistani cooperation. Such a visit was coveted by Musharraf, partly as a sign of his government's legitimacy. He told the two envoys that he would meet with Mullah Omar and press him on  Bin Laden. They left, however, reporting to Washington that Pakistan was unlikely in fact to do anything," given what it sees as the benefits of Taliban control of Afghanistan." President Clinton was scheduled to travel to India. The State Department felt that he should not visit India without also visiting Pakistan. The Secret Service and the CIA, however, warned in the strongest terms that visiting Pakistan would risk the President's life. Counterterrorism officials also argued that Pakistan had not done enough to merit a presidential visit. But President Clinton insisted on including Pakistan in the itinerary for his trip to South Asia. His one-day stopover on March 25, 2000, was the first time a U.S. president had been there since 1969. At his meeting with Musharraf and others, President Clinton concentrated on tensions between Pakistan and India and the dangers of nuclear proliferation, but also discussed  Bin Laden. President Clinton told us that when he pulled Musharraf aside for a brief, one-on-one meeting, he pleaded with the general for help regarding  Bin Laden." I offered him the moon when I went to see him, in terms of better relations with the United States, if he'd help us get  Bin Laden and deal with another issue or two." The U.S. effort continued. <sep>What did President Clinton's visit with Pakistan include?<sep>Tensions between Pakistan and India

Yes

Heat supplies the energy that causes motion. The deeper you go into toward the Earths core, the hotter it gets. At the core it is really hot. All that heat tries to rise toward the surface. In the Mantle, the rock is partially melted and is able to move. As it is heated, the material in the mantle moves toward the surface. As the mantle material rises, it cools. When it reaches the Earths crust, it is mostly stopped. A little of the material can break through the surface, but not all. Instead, it begins to move horizontally. The mantle material moves horizontally away from a mid-ocean ridge crest. Toward the surface, the mantle material starts to cool. As it cools it sinks back down into the mantle. These areas are where deep sea trench occur. The material sinks back down to the core. The system operates like a giant conveyor belt. The motion due to heating and cooling is called convection. <sep>Where do sea trenches occur?<sep>Surface

The factory is highly automated and designed to shift flexibly to produce many different kinds of chips to suit demand. "The diversity is the big difference with this plant," said Richard Doherty, president of Envisioneering, a research firm. "It gives IBM the capability to make so many different kinds of custom chips, and the world is going to custom chips." The 140,000-square-foot plant is a testament to advanced manufacturing technology. The 300-millimeter silicon wafers -- about the size of a standard pizza -- are shuttled around the facility in enclosed plastic pods, which ride on overhead tracks. They drop down from wires automatically into machines, sheathed in stainless steel and glass, for each stage of processing and fabrication. Throughout the 500 processing steps, which typically last 20 days, the wafers are not touched by human hands. The circuits etched into the chips are less than one thousandth the width of a human hair. Human operators are there to monitor the systems, catch errors and fine-tune the production process for maximum efficiency. Because each of the hundreds of processing machines is self-enclosed, and essentially airtight, the uniforms operators wear are less constricting than in the previous generation of chip plants, which looked like space suits. The operators at the East Fishkill factory wear light nylon uniforms, light blue shoe coverings and translucent hair nets made of paper. They look more like workers in a bakery. Yes, said Richard Brilla, director of the new facility, "but the donuts are a lot more costly here." Each wafer, holding hundreds of chips, is worth $6,000 to $10,000 apiece, depending on what insulation, circuitry and materials are used. <sep>What enables IBM to make different kinds of custom chips?<sep>Hundreds of processing machines
