On December 26, 2004, an earthquake estimated at between magnitude 9.0 and 9.3 resulted from rupture of over 1000 km (620 mi) of the Andaman Subduction Zone. The rupture also generated a tsunami that caused damage throughout the Indian Ocean, killing some 250,000 people and causing billions of dollars in damage. The tsunami was the most devastating in more than 40 year and one of the largest such events on record.

Multihull ships consist of multiple hulls performing essentially the same flotation function as that of a conventional single-hull ship (monohull). The most familiar, and the oldest example, of a multihull vessel is a Pacific islander outrigger canoe (or proa). When compared to a conventional western monohull canoe, the additional hull or hulls on the outrigger primarily provides additional stability in ocean waves.

One of the four subclasses of the class Mammalia. Prototheria contains a single order, the Monotremata. No ancestral genera of fossil monotremes are known, and the structure of the living monotremes is so specialized that the affinities of the Prototheria are largely conjectural. Most mammalogists believe that the prototheres arose from a different stock of therapsid reptiles than the one that gave rise to the Theria.

One of the earliest aromatics mentioned in literature. The plant, <i>Pimpinella anisum</i> (Apiaceae), is an annual herb about 2 ft (0.6 m) tall and a native of the Mediterranean region. It is cultivated extensively in Europe, Asia Minor, India, and parts of South America. The small fruits are used for flavoring cakes, curries, pastry, and candy. The distilled oil is used in medicine, soaps, perfumery, and cosmetics.

Particle flow is important to many industrial processes, including the pneumatic conveying of solids, transport of solids in liquids (slurries), removal of particulates from gas streams for pollution control, combustion of pulverized coal, and drying of particulates in the food and pharmaceutical industries. The vast majority of flow problems in industrial design involve the flow of gas or liquids with suspended solids.
Industry:Science
Movement of signals or cues, presumably chemical, among individual plants or plant parts. These chemical cues are caused by damage to plant tissues or other stresses and stimulate physiological changes in the undamaged “receiving” plant or tissue. Communication among plants often involves induced plant defenses, which are chemicals produced actively by an individual plant in response to attack by insects or disease agents.

Networked systems are vulnerable to cyber attacks in which computer programs—variously called bots, spiders, scrapers, and so forth—pose as legitimate human users. Abuses have included defrauding financial payment systems, creating vast numbers of accounts for sending unsolicited email (“spamming”), stealing personal information, skewing rankings and recommendations in online forums, and ticket scalping, to name but a few.

Paper documents are ubiquitous in our society, but there is still a need to have many of these documents in electronic form. There are large collections of data originating in paper form, such as office data, books, and historical manuscripts, that would benefit from being available in digital form. Once converted to electronic form, the documents can be used in digital libraries or for wider dissemination on the Internet.
Industry:Science
Polymers derived from hydrocarbon molecules that possess one or more alkenyl (or olefinic) groups. The term polyolefin typically is applied to polymers derived from ethylene, propylene, and other alpha-olefins, and from isobutylene, cyclic olefins, and butadiene and other diolefins. Polymers produced from other olefinic monomers, such as styrene, vinyl chloride, and tetrafluoroethylene, generally are considered separately.
Industry:Science
Single cells or aggregates of cells whose principal function is thought to be mechanical support of plants or plant parts. Sclerenchyma cells have thick secondary walls and may or may not remain alive when mature. They vary greatly in form and are of widespread occurrence in vascular plants. Two general types, sclereids and fibers, are widely recognized, but since these intergrade, the distinction is sometimes arbitrary.
