Input: (CNN) -- English club Chelsea have completed the signing of Oriol Romeu from Spanish and European champions Barcelona. The 19-year-old is currently playing for Spain at the World Under-20 Championships in Colombia and has signed a four-year deal with last season's Premier League runners-up. The deal is worth $7 million and includes a buy back clause, set at $14 million after the first year and $21 million after the second. Romeu started his career at Barcelona's city rivals Espanyol before joining the Camp Nou academy in 2004. The midfielder, who can also play in central defence, made his debut for Barcelona in last season's Spanish Supercup match with Seville and got his first taste of league action against Deportivo in May 2010. He has played 90 minutes in both of Spain's games at the World Under-20 Championships, when they beat Costa Rica and Ecuador. Chelsea official web site confirmed the signing and said Romeu is "renowned for his strength and his expansive passing ability." Another player leaving Barcelona is Jeffren Suarez after he agreed to join Sporting Lisbon. The Portuguese outfit have paid $5 million for the 23-year-old which, like the Romeu deal, includes a buy back option. Jeffren joined Barca from Tenerife in 2004 and made his debut for the Catalan club in the 2006-07 season.

The earliest signs of people on Jamaica are the remains of the Arawak, an AmerIndian society that originated on the north coast of South America. Arawak peoples migrated to various Caribbean islands, arriving in Jamaica by the beginning of the eighth century. They were peaceful and lived by "slash-and-burn" farming. For meat, they bred pigs and ate iguana, both native to the island. They were highly skilled in such manual activities as thatching and weaving. In fact, the hammock was an AmerIndian invention that remains with us today; it is an object which, more than any other, evokes an image of a warm sunny day on a tropical isle. The Arawak left a legacy of paintings in places such as Runaway Caves near Discovery Bay, and shards of pottery found at their settlements near Nueva Sevilla and Spanish Town have added a little to our knowledge about them. Over 200 Arawak sites have been identified, and it is said that when the Spanish arrived in Jamaica there were approximately 100,000 Arawak living on the island. They called Jamaica "Xaymaca" ("land of wood and water"). Columbus and the Arrival of Europeans Columbus first arrived in Jamaica on 5 May 1494 at Discovery Bay, where there is now a small park in his honor. He stayed for only a few days but returned in 1502, landing here when the ships of his fleet became unserviceable; he waited at St. Ann's Bay for help to arrive from Cuba. After the death of Columbus in 1505, Jamaica became the property of his son Diego, who dispatched Don Juan de Esquivel to the island as Governor. Esquivel arrived in 1510 and created a base called Nueva Sevilla near St. Ann's Bay, from which he hoped to colonize the rest of the island. The Spanish immediately began subjugating the Arawak population, many of whom died under the yoke of oppression and of diseases carried by the Europeans. A number of them committed suicide rather than live the life created for them by the Spanish. The site of Nueva Sevilla proved to be unhealthy and mosquito-ridden, and in 1534 the Spanish founded Villa de la Vega, today known as Spanish Town. Pig breeding was the main occupation of these early settlers, but they also planted sugar cane and other crops that required large numbers of laborers. The number of Arawak had already fallen dramatically, so the Spanish began to import slaves from Africa to work the land; the first Africans arrived in 1517.

A handful of Bronze Age relics has fostered an assumption that prehistoric settlers inhabited Ibiza thousands of years ago. Greater evidence of such a people is found on Mallorca and Menorca than on Ibiza, but one of the Balearics' most important sites is actually on the island of Formentera, where the megalithic monument/tomb of Ca Na Costa has been dated to 2000 b.c. Ibiza's key location between Africa and ancient Iberia made it a convenient stopover for Mediterranean seafarers, such as the Phoenician traders, who called the island Ibosim. The Greeks dubbed it Ebysos, the Romans called it Ebusus, and the Moors, Yebisah. The Carthaginians: A detailed history of the island doesn't begin until it became a colony of Carthage in the 7th century b.c. . The Carthaginians originally came from the area comprising present-day Lebanon, and from their bases in North Africa and what's now Spain, they challenged the Roman Empire for domination of the Mediterranean region. Their interest in Ibiza lay partly in its vast salt flats, which to this day remain the source of a profitable industry. They capitalized on the natural resources by using the salt to cure fish, which they exported to their home country. The Carthaginians also carried out lead mining and continued to be of significance up until this century. It is believed that the lead pellets which were used by the Carthaginian general Hannibal were made on Ibiza. The Carthaginians also considered the island a holy place, and here in great splendour they buried thousands of their citizens in a huge necropolis on the Puig des Molins (Hill of the Windmills) below the Dalt Vila (Old Town) of Ibiza. Under the gnarled olive trees archaeologists have uncovered a treasure trove of statues, jewellery, pitchers, tools, and coins, which are now displayed in the town's two archaeological museums. The Romans never really infiltrated Ibiza, and even after the defeat of Hannibal in 202 b.c. during the Second Punic War their influence was restrained. Only with the fall of Carthage in 146 b.c. did they manage to make inroads, but, as local historians stress, Ibiza was neither conquered nor annexed by Rome, but confederated, retaining remarkable autonomy. For centuries to come the old Carthaginian traditions were allowed to continue on Ibiza alongside the new Roman way of life.

Breathing is the process of moving air into and out of the lungs. The process depends on a muscle called the diaphragm. This is a large, sheet-like muscle below the lungs. Inhaling, or breathing in, occurs when the diaphragm muscle tightens. This increases the size of the chest. This too decreases air pressure inside the lungs. This action allows air and gases to enter the lungs. Exhaling, or breathing out, occurs when the diaphragm muscle relaxes. This decreases the size of the chest. This increases air pressure inside the lungs. This action allows for air to leave the lungs. When you inhale, air enters the respiratory system through your nose and ends up in your lungs, where gas exchange with the blood takes place. What happens to the air along the way? In the nose, mucus and hairs trap any dust or other particles in the air. The air is also warmed and moistened. Next, air passes through a passageway that is connected to the windpipe. The air then finds its way to the lungs. In the chest, the windpipe splits so that air enters both the right and left lung.
