The earthquake caused great concern around the Indian Ocean that it might trigger a tsunami similar to the massive one generated three months earlier by the 2004 Indian Ocean earthquake on December 26, 2004. Evacuations were carried out in coastal regions of Thailand, Malaysia, and Sri Lanka. This earthquake, however, produced a relatively tiny tsunami. A three-meter tsunami caused moderate damage to port and airport facilities on Simeulue, and a two-meter tsunami was recorded on the west coast of Nias. Much smaller waves, most detectable only in tide gage recording systems, were recorded across the Indian Ocean; for example, a 25 cm wave was recorded at Colombo, Sri Lanka.
Tsunami warnings were issued by the Pacific Tsunami Warning Center, operated by the US National Oceanic and Atmospheric Administration (NOAA) [3], and by the government of Thailand. There were initial concerns that a major tsunami could be generated, particularly travelling south from the event's hypocenter.
Portions of Thailand's southern coast were evacuated as a precaution, and NOAA advised an evacuation of 600 miles of coastline in Sumatra. Evacuations also occurred in the northern Malaysian states of Penang and Kedah, as well as the eastern coast of Sri Lanka, where ten people were killed in the confusion of the evacuation. Many of the southern states of India were also put on high alert; all of these areas had seen significant damage from December's tsunami. After the detection of a minor tsunami south of the epicenter, including a 30 cm tsunami on Australia's Cocos Islands, the island states of Mauritius, Madagascar, and the Seychelles in the Indian Ocean issued warnings to their populations.
Although tsunami warning systems for the region had been actively discussed since the December 2004 earthquake, none had yet been implemented in the Indian Ocean.

The 2005 Sumatra earthquake was a major earthquake on March 28, 2005, located off the west coast of northern Sumatra, Indonesia. Approximately 1300 people were killed by the earthquake, mostly on the island of Nias. The event caused panic in the region, which had recently been devastated by the massive tsunami triggered by the 2004 Indian Ocean earthquake, but this earthquake generated a relatively tiny tsunami that caused limited damage.
The earthquake occurred at 16:09:36 UTC (11:09:36 p.m. local time) on March 28, 2005. The hypocenter was located at 2 04 35 N, 97 00 58 E, 30 km (18.6 miles) below the surface of the Indian Ocean, where subduction is forcing the Indo-Australian Plate to the south-west under the Eurasian plate Sunda edge. The area is 200 km west of Sibolga, Sumatra, or 1400 km northwest of Jakarta, roughly halfway between the islands of Nias and Simeulue. Seismic recordings give the earthquake a magnitude of about 8.7, and effects were felt as far away as Bangkok, Thailand, a distance of 1000 km

A mouse is a mammal that belongs to one of numerous species of small rodents in the genus Mus and various related genera of the family Murid (Old World Mice).
The best known mouse species is the common house mouse (Mus musculus). It is found in nearly all countries and, as the laboratory mouse, serves as an important model organism in biology; it is also a popular pet. (Non-biologists often use the term "mouse" synonymously with "Mus musculus"). The American white-footed mouse (Peromyscus leucopus) and the deer mouse (Peromyscus maniculatus) also sometimes live in houses. These species of mice live commensally with humans. Although they may live up to two years in the lab, the average mouse in the wild lives only 3 months, primarily due to heavy predation.
Mice are very common experimental animals in biology and psychology primarily because they are mammals, and thus share a high degree of homology with humans, but can be manipulated in ways that would be considered unethical to do with humans. Additional benefits include the fact that mice are small, relatively inexpensive, and several generations can be observed in a short period of time. The mouse genome has been sequenced, and many genes which share homology to human genes have been identified. In the 2006 Biosatellite project, a group of mice will orbit Earth inside a spinning spacecraft to determine how mice react to gravity equivalent to that of Mars.
However, mice can also be harmful pests, damaging and eating crops and spreading diseases through their parasites and feces. The domestication of cats is thought to have been for their predation of mice and their relatives, the rats. A mouse trap can also be used to catch mice.
Mice generally live on a herbivore diet, but are actually omnivores: they will eat meat, the dead bodies of other mice, and have been observed to cannibalise their tails during starvation.
An estimated half million mice live on the London Underground, mostly running around the tracks.
Mice cannot see colors, but they can see the difference between colors, because they see things in shade from black to white.

A monkey is any member of two of the three groupings of simian primates. These two groupings are the New World and Old World monkeys of which together there are nearly 200 species. Because of their similarity to monkeys, apes such as chimpanzees and gibbons are sometimes incorrectly called monkeys. Also, a few monkey species have the word "ape" in their common name. Because they are not a single coherent group, monkeys do not have any important characteristics that they all share and are not shared with the remaining group of simians, the apes.
Monkeys range in size from the Pygmy Marmoset, at 10 cm (4 inch) long (plus tail) and 120 g (4 oz) in weight to the male Mandrill, almost 1 metre (3 ft) long and weighing 35 kg (75 lb). Some are arboreal (living in trees), some live on the savanna; diets differ among the various species but may contain any of the following: fruit, leaves, seeds, nuts, flowers, insects, spiders, eggs and small animals.
Some characteristics are shared among the groups; most New World monkeys have prehensile tails while Old World monkeys do not; some have trichromatic colour vision like that of humans, others are dichromats or monochromats. Although both the Wew and Old World monkeys, like the apes, have forward facing eyes, the faces of Old World and New World monkeys look very different though again, each group shares some features such as the types of noses, cheeks and rumps. To understand the monkeys, therefore, it is necessary to study the characteristics of the different groups individually.

Human beings define themselves in biological, social, and spiritual terms. Biologically, humans are classified as the species Homo sapiens (Latin for "wise man" or "clever human"): a bipedal primate belonging to the superfamily of Hominoidea, with all of the other apes: chimpanzees, bonobos, gorillas, orangutans, and gibbons.
Humans have an erect body carriage that frees the upper limbs for manipulating objects, a highly developed brain and consequent capacity for abstract reasoning, speech, language, and introspection. One current hypothesis within the scientific community is that the human evolution of bipedalism (two-legged locomotion) occurred in response to a need for long-distance running. Humans are said to be one of a short list of animals with such a capacity. Another theory is that this allowed human predecessors to see above the tall grasses of the African plains.
The human mind has several distinct attributes. It is responsible for the complexity of human behaviour, especially language. Curiosity and observation have led to a variety of explanations for consciousness and the relation between mind and body. Psychology, especially neuropsychology, attempts to study them from the scientific point of view. Religious perspectives generally emphasise a soul, qi or atman as the essence of being, and are often characterised by the belief in and worship of God, gods or spirits. Philosophy, especially philosophy of mind, attempts to fathom the depths of each of these perspectives. Art, music and literature are often used in expressing these concepts and feelings.
Humans are inherently social. Humans create complex social structures composed of many co-operating and competing groups. These range from nations and states down to families, and also from the community to the self. Seeking to understand and manipulate the world around us led to the development of technology and science as a social, rather than an individual, enterprise. These institutions have given rise to shared artefacts, beliefs, myths, rituals, values, and social norms which form the group's culture.

Iptelecoms, the UK distributors for Swyx and specialists in the distribution of IP telephony products, found they had a major success on their hands when exhibiting at the 2005 Convergence Summit held at Stoneley Park near Coventry on the 6th and 7th of August this year.
Steve Curtis, Managing Director of Iptelecoms Ltd said The exhibition has been a major success story for us. This is the first time that we have exhibited at the Convergence Summit and we are delighted with the astounding interest shown in our product line-up. He also told us Over the past few weeks we have seen a major upturn in business and the time is most definitely now for IP telephony and converged solutions. Resellers are realizing that this is the only route forward and the move to IP opens up many additional revenue streams to them.
On several occasions dealers were waiting in line for a live Swyx demonstration whilst many other stands were visibly quieter.
Iptelecoms work closely with their reseller channel to ensure they fully understand the feature rich products that they are taking to market.
Mark Russell, Technical Director at Iptelecoms who has over 6 years experience with Swyx SoftPBX told us Watching the expressions on peoples face turn into a booming smile as they were shown the feature rich product was amazing. Ive never experienced anything quite like it. Having been in the telecoms industry for over 20 years and worked with the data industry for over 8 years we are ideally placed to both help our voice resellers understand the issues associated with entering the world of converged networks and our data resellers how the product should be taken to market.
Those resellers wishing to partner with Iptelecoms should either obtain further information from http://www.iptelecoms.com or email sales@iptelecoms.com.

In older video cameras, prior to the 1990s, a video camera tube or pickup tube was used instead of a charge-coupled device (CCD). Several types were in use from the 1930s to the 1980s. They operate in a somewhat similar manner to cathode ray tubes, which display pictures, but are instead used to capture images that are projected onto them through the camera lens system.

Fail-deadly is a concept in military strategy which encourages deterrence by guaranteeing an immediate, automatic and overwhelming response to an attack. Under fail-deadly nuclear deterrence, policies and procedures controlling the retaliatory strike will authorize launch even if the existing command and control structure has already been neutralized.
Fail-deadly is also associated with "massive retaliation", a deterrence strategy which ensures that the counter strike will be conducted on a larger scale than the initial attack. Basically, if an aggressor launched one missile at another party, they would get ten in return. If they launched ten, they would receive 100, and so on.
A more prosaic example of a fail-deadly instrument is a dead man's switch which must be constantly held to prevent the triggering of an explosive, which ensures that a suicide bombing is not prevented by killing the person with the bomb.

In February 1996, IBM's chess computer Deep Blue defeated Kasparov in one game using normal time controls, in Deep Blue - Kasparov, 1996, Game 1.
However, Kasparov retorted with 3 wins and 2 draws, soundly winning the match. In May 1997, an updated version of Deep Blue defeated Kasparov. This was the first time a computer had ever defeated a world champion. IBM keeps a web site of the event at http://www.chess.ibm.com/ Kasparov suspected IBM of cheating and using a human player to help the computer. The film Game Over: Kasparov and the Machine documents this.
Kasparov has been credited with the invention of Advanced Chess in 1998, as a new form of chess in which a human and a computer join their forces.
In November 2003, he engaged in a four game match against chess playing computer program X3D Fritz (which was said to have an estimated rating of 2807), using a virtual board, 3D glasses and a speech recognition system. The first was a draw, X3D won the second after Kasparov blundered when short of time, Kasparov won the third, and the last game was a draw. The X3D Man-Machine World Chess Championship match ended in draw. Kasparov received $175,000 for the result and took home the golden trophy. Kasparov continued to criticize the blunder in the second game that cost him a crucial point. He felt that he had outplayed the machine overall and played well. "I only made one mistake but unfortunately that one mistake lost the game."

clown today is one of various types of performer in the circus and rodeo, normally appearing in makeup, costume (typically large footwear, oversized clothing , bright colors and patterns), wig and fun nose, and enacting humorous sketches, usually in the interludes between major presentations. The clown's humor today is basically visual and includes many elements of slapstick.
Clowning is a very ancient art form, which appears in some way or other in virtually every culture. An early form of clowns was the court jester, a role that can be traced back to ancient Egypt. Though most jesters suffered from some physical deformity and were often the butt of jokes, they were also the only courtiers who enjoyed free speech, and could speak their minds to the monarch. Usually...
Each individual circus clown has the informal right to a costume and makeup that may not be infringed by other clowns. Despite no enforcement through intellectual property laws, this right is always respected, and even extended to individual routines and acts. All clowns (at least in Britain) have their faces painted onto eggshells and no two eggs can be alike.
