This information was systematically organized in the 2nd century , and in the following century a sound corpus was agreed upon. This, coupled with the habit of learning by rote (which was developed from the basically traditional character of knowledge that encouraged learning more than thinking), impoverished intellectual creativity still further. Both the Sunni and the Shi?ah medieval systems of learning, however, have come face to face with the greatest challenge of allthe impact of modern education and thought. When higher learning in the form of tradition grew in the 8th and 9th centuries, it was centred around learned men to whom students travelled from far and near and from whom they obtained a certificate ( ijazah ) to teach what they had learned. With the advent of the Turks, the famous vizier created an important college at Baghdad, devoted to Sunni learning, in the latter half of the 11th century. ad-Din al-Ayyubi), after ousting the Fa?imids, consecrated it to Sun! ni learning in the 12th century. Throughout subsequent centuries, colleges and quasi-universities (called madrasah or ) arose throughout the Muslim world from Spain (whence philosophy and science were transmitted to the Latin West) across Central Asia to India. learn sunni

Thus the engines of war were devices such as catapults, floating bridges, and assault towers; their designer was the engine-er, or military engineer. The counterpart of the military engineer was the civil engineer, who applied essentially the same knowledge and skills to designing buildings, streets, water supplies, sewage systems, and other projects. Associated with engineering is a great body of special knowledge; preparation for professional practice involves extensive training in the application of that knowledge. The scientist adds to the store of verified, systematized knowledge of the physical world; the engineer brings this knowledge to bear on practical problems. Civil engineering emerged as a separate discipline in the 18th century, when the first professional societies and schools of engineering were founded. Civil engineers of the 19th century built structures of all kinds, designed water-supply and sanitation systems, laid out railroad and highway networks, and ! planned cities. England and Scotland were the birthplace of mechanical engineering, as a derivation of the inventions of the Scottish engineer James Watt and the textile machinists of the Industrial Revolution. engin knowledg

Fixed oils and fats have the same chemical composition: they consist chiefly of glycerides, resulting from a reaction between an alcohol called glycerol and certain members of a group of compounds known as fatty acids. Linseed, tung, and other drying oils ( i.e., those that are highly unsaturated) and large quantities of soybean, sunflower, and safflower oils are used in paints, varnishes, and alkyd resins. Considerable quantities of specialty oils and sulfonated oils are used in leather dressing and textile manufacture. Castor oil, for example, has a strong purgative action; fish-liver oils are sources of vitamins A and D; and others such as lard, olive oil, and almond oil serve as vehicles in pharmaceutical preparations. oil oil,

Once ranging over the entire continent and beyond, hippos now live in eastern, central, and parts of southern Africa. Although often seen basking in the sun, hippos lose water rapidly through the skin and become dehydrated without periodic dips. Hippos, however, eat relatively little vegetation for their size (about 35 kg [80 pounds] per night), as their energy requirement is low because they are buoyed in warm water much of the time. Hippos do not chew cud but retain food for a long time in the stomach, where protein is extracted by fermentation digestion. As a result, hippos have long had a largely undeserved reputation as aggressive animals. Cows live in schools, but they are not permanently associated with other cows, though sometimes they maintain bonds with offspring for some years. Males mature at about 8 years of age, but dominant bulls more than 20 years old do most of the . Hippos were extinct in northern Africa by 1800 and south of and the by 1900. There remains a! demand for hippo teeth as a fine-grained that is easy to carve; it was once used to make false teeth. The pygmy hippo is less aquatic than its larger relative, although when pursued it hides in water. These groups diverged from other members of the order about 45 million years ago, but molecular studies suggest that hippos and (whales and dolphins) have an earlier common ancestor and may be more closely related. A fossil resembling today's pygmy hippo dates to the Early (23.8 million to 16.4 million years ago). Hippos eventually reached Europe and Asia, though climate changes and overhunting by humans exterminated all species outside Africa by the end of the (1,800,000 to 10,000 years ago). , The Long African Day (1972), features hippos in this classic work, which celebrates African wildlife. hippo year

The Hawaiians were a brown-skinned people with straight or wavy black hair. Hawaiian society's basic unit of land, the ahupuaa, usually extended from the shore to the mountaintop, with rights in the adjoining sea waters, so that the occupants had the means of supplying all their wantsthe sea for fish; the littoral for coconuts; the valley for taro, their principal food; the lower slopes for sweet potatoes, yams, and bananas; and the mountain for wood. Within the ili were small areas, kuleanas, occupied by the common people, who also had certain rights of fishery, water, and mountain products. Elaborate systems of water rights were evolved. Without metals, pottery, or beasts of burden, the people made implements, weapons, and utensils of stone, wood, shell, teeth, and bone, and great skill was displayed in arts and industries. Houses were of wood frames and thatched, with stone floors covered with mats. Food was cooked in holes in the ground, called imus, by means of hot ston! es; but many foods, including fish, were often eaten raw. The Hawaiians excelled in athletics. The first indentured Chinese field hands arrived in 1851, and the first Japanese in 1868; these and other foreigners eventually overwhelmed the native Hawaiians. APA style: Hawaiian. hawaiian right

The dividing and reuniting of river channelsa phenomenon known as braidinghas created several islands along the river's middle course, of which the two largest are Elephant Island and . The river valley is cut into a plateau of sandstone dating from the Tertiary period (66.4 million to 1.6 million years ago). Dense mangrove swamps fringe the lower river for 60 miles (97 km) inland, after which freshwater swamps and salt flats on low-lying stretches alternate with dense clumps of small trees and shrubs that line the cliffs. The river abounds in fish and river The grass-covered river flats (known locally as ) of the lower river are rendered useless for cultivation by the salt water that periodically inundates them, and settlements on them are few. The flats of the middle and upper river are of some agricultural value, however. Cultivation and settlement have therefore taken place in the middle flats and on the higher slopes, with many villages being located on the borderline b! etween the flats and the plateau, thus avoiding both the flooding of the lower slopes and the increasing aridity of the higher terrain. river flat

Enmerkar therefore requested his sister, the goddess , to aid him in acquiring material and manpower from Aratta; she agreed and advised him to send a threatening message to the lord of Aratta. Though Enmerkar complied, the lord of Aratta refused to complete his part of the agreement; threatening messages were again sent out by both men, each claiming the aid and sanction of the goddess Inanna. The other epic relating the defeat of Aratta is known as Enmerkar and Ensuhkeshdanna . Although the members of Ensuhkeshdanna's council advised him to comply with Enmerkar, he listened instead to a local priest, who promised to make Uruk subject to Aratta. A third epic, Lugalbanda and Enmerkar , tells of the heroic journey to Aratta made by Lugalbanda in the service of Enmerkar.
