To protect its seagoing interests and trade routes, Portugal established strategic garrisons in Goa (India), Malacca (East Indies), and Hormuz in the Persian Gulf. Portuguese explorers then embarked upon Macau (now Macao), the Congo, and various other parts of Africa, including the Sudan. The Portuguese policy was to avoid armed strife and to develop a trade empire, rather than to conquer nations. To this end it succeeded with relatively few blood-soaked episodes in its colonial history. Adventures abroad, however, proved disastrous during the second half of the 16th century. In 1557 the 14-year-old boy-king Sebastiao ascended the throne, the beginning of a calamitous reign that was to end at the battle of Alcacer-Quiber (Morocco) in pursuit of a vain crusade. Sebastiao's untimely demise, alongside some 18,000 ill-prepared, badly led followers, set the stage for a crisis of succession. For many years afterwards, legends and rumors bizarrely insisted that the king was still alive, and imposters turned up from time to time claiming the throne; those who were plausible enough to be deemed a threat were summarily executed. In fact, the only rightful claimant to the crown was the elderly Prince Henry. But after two years of alternating between the throne and his sickbed, he died, heirless. Surveying the situation and smelling an opportunity, Spain occupied the power vacuum, and Portugal's neighbor and long-time antagonist became its master. Spanish rule dictated Portugal's inadvertent involvement in Spain's ongoing wars. In 1587 a squadron of British ships commanded by Francis Drake attacked the Algarve (now a "legitimate target" as Spanish territory) and sacked Sagres, thus depriving the world of the relics of Henry the Navigator. Nine years later Faro was torched. The 1386 Treaty of Windsor, by which Britain and Portugal had pledged eternal friendship, seemed a distant memory. Portugal's empire was gradually eroded, and many of its trading posts (with the notable exception of Brazil) were picked off by the British and Dutch. Finally, after 60 years of Spanish rule, Portuguese noblemen (aided by the French, then at war with Spain) organized a palace coup and restored independence. The Great Disaster Portugal's greatest misfortune struck on All Saint's Day, 1 November 1755.

Roberta Adams skipped the thick how-to guide on child-custody forms and sat down at a computer at the Lamoreaux Justice Center in Orange on Wednesday. The Garden Grove woman answered a series of questions to create and print a form to file with the court. "It's easy," said Adams, 25. "I thought I'd have all kinds of questions and have to take the forms home." A University of California, Irvine, study released Wednesday found an interactive computer system effectively helps people fill out paperwork for restraining orders, eviction defense, small-claims cases and requests for filing-fee waivers. Not only does the system make life easier for people who can't afford a lawyer, but it also might improve efficiency in the courts because the forms, which are printed out when completed, are easy to read and are being filled out correctly, the study found. Since the program started in 2000, more than 6,000 people have used the free system, located in public buildings throughout Orange County. The system was developed by the Legal Aid Society of Orange County with about $800,000 in grants. The program avoids legal jargon, offers a courthouse video tour and sticks to a fifth-grade vocabulary. Users can choose English, Spanish or Vietnamese. Kiosks are in courthouses in Fullerton and Orange, the district attorney's family-support office, the Legal Aid Society in Santa Ana, Irvine City Hall and the San Juan Capistrano Library. The program is also available online. Bob Cohen, executive director of Legal Aid, said the study should clear the way for expansion throughout California. Locally, a program for divorce petitions will be added this summer. Cohen said the system proves the benefit of technology tailored to those who aren't computer-savvy. He said much of the technology now available requires Internet skills and access. Low-income people, however, have less access to computers and less experience using them. "Our clients have to catch up, and they have to become a part of the mainstream," Cohen said.

Question: "Where can the program be accessed from?"

Response: "It can be accessed from the offices of Legal aid"

Problem: 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.

Question: "Why does the system work as a conveyor belt?"

Answer: "Due to motion"

ATLANTA, Georgia (CNN) -- On a plot of soil, nestled against the backdrop of skyscrapers in downtown Atlanta, Georgia, a group of residents are turning a lack of access to fresh produce into a revival of old traditions and self-empowerment. Urban farming is a way for African-Americans to connect with the earth, says Cashawn Myers of HABESHA. HABESHA Gardens is one of many urban gardens sprouting up around the country. Fruits and vegetables are thriving in this community garden located in an economically depressed area of the city known as Mechanicsville. But the garden serves an even greater purpose. The harvest helps feed some of the neediest members of the neighborhood. "It's a reawakening going on. It's almost like it's a renaissance," says Cashawn Myers, director of HABESHA Inc. "There's a Ghanaian proverb that says Sankofa. Sankofa means return to your past so you can move forward. Even if you look at coming over here during our enslavement, we were brought here to cultivate the land because that's something we did on the continent. So really, that's what many of the people are doing now," he said. Myers believes urban farming is a way for many African-Americans to reconnect with their past. iReport.com: Show us your urban farm "They are going through a process of Sankofa and going to what they traditionally did, which is connect to the Earth so they can move forward and grow," he says. But HABESHA Gardens isn't unique. Former pro basketball player Will Allen, who is considered to be one of the nation's leading urban farmers and founder of Growing Power Inc., estimates that there are hundreds of thousands of urban gardens in inner cities across America. Urban farms help feed people, sustain neighorhoods " "It's beyond a movement at this point. Its more like a revolution," says Allen.

Question: "What are urban farms used for?"
