On August 17, 2007, Dell Inc. announced that after an internal investigation into its accounting practices it would restate and reduce earnings from 2003 through to the first quarter of 2007 by a total amount of between $50 million and $150 million, or 2 cents to 7 cents per share. The investigation, begun in November 2006, resulted from concerns raised by the U.S. Securities and Exchange Commission over some documents and information that Dell Inc. had submitted. It was alleged that Dell had not disclosed large exclusivity payments received from Intel for agreeing not to buy processors from rival manufacturer AMD. In 2010 Dell finally paid $100 million to settle the SEC's charges of fraud. Michael Dell and other executives also paid penalties and suffered other sanctions, without admitting or denying the charges.
Who did Dell agree to not buy processors from?
AMD

Farming had been a traditional occupation for centuries, although it became less dominant in the 20th century with the advent of tourism. Grazing and pasture land are limited because of the steep and rocky topography of the Alps. In mid-June cows are moved to the highest pastures close to the snowline, where they are watched by herdsmen who stay in the high altitudes often living in stone huts or wooden barns during the summers. Villagers celebrate the day the cows are herded up to the pastures and again when they return in mid-September. The Alpanschluss or Desalpes ("coming down from the alps") is celebrated by decorating the cows with garlands and enormous cowbells while the farmers dress in traditional costumes.
What made farming less dominant in the 20th century?
tourism

The structure of QD-LEDs used for the electrical-excitation scheme is similar to basic design of OLEDs. A layer of quantum dots is sandwiched between layers of electron-transporting and hole-transporting materials. An applied electric field causes electrons and holes to move into the quantum dot layer and recombine forming an exciton that excites a QD. This scheme is commonly studied for quantum dot display. The tunability of emission wavelengths and narrow bandwidth is also beneficial as excitation sources for fluorescence imaging. Fluorescence near-field scanning optical microscopy (NSOM) utilizing an integrated QD-LED has been demonstrated.
During the electrical-excitation scheme, what moves into the quantum dot layer?
electrons and holes
