A tsunami has a much smaller amplitude (wave height) offshore, and a very long wavelength, which is why they generally pass unobserved at sea, forming only a passing bulge in the ocean. Tsunami have been historically referred to as tidal waves because as they approach land, they take on the characteristics of a vicious onrushing tide rather than the sort of cresting waves that are formed by wind action upon the ocean. Since they are not really related to tides the term is considered misleading and its treatment is discouraged by oceanographers.

Pets
Koko the gorilla is one of few examples of a non-human animal which has had an explicit pet. Using sign language, she requested a cat; her first pet was a kitten named All Ball, to which she was reported to be quite attached and mourned for several days after the cat escaped and was killed by a car.
The GloFish is a genetically modified fluorescent zebrafish with bright red, green, and orange fluorescent color. It is the first genetically modified animal to become available as a pet.

Calculator
In the past, some calculators were as huge as today's computers. The first automatic calculators were mechanical desktop devices which were replaced by electromechanical desktop calculators, and then by electronic devices using first sung valves, then transistors, then hard-wired integrated circuit logic. New calculators are electrically powered and come in innumerable shapes and sizes varying from cheap, give-away, credit-card sized models to more sturdy adding machine-like models with built-in printers.

Computer networking
Computer networking is the engineering discipline anxious with communication between computer systems. Such communicate systems comprise a computer network and these networks generally involve at least two devices able of being networked with at least one usually being a computer. The devices can be separated by a small number of meters or nearly unlimited distances. Computer networking is sometimes considered a sub-discipline of telecommunications, and sometimes of computer science, information technology and computer engineering. Computer networks rely a lot upon the abstract and practical application of these scientific and engineering disciplines.

Hybrid deer
Both male Mule Deer/female White-tailed Deer and male White-tailed Deer/female Mule Deer matting have formed hybrids. Hybrids have been reported in the wild but are disadvantaged because they don't correctly inherit survival strategies. Mule Deer move with bounding leap to escape predators. Slotting is so specialized that only 100% heritably pure Mule Deer seem able to do it. In captive hybrids, even a one-eighth White-tail/seven-eighths Mule Deer hybrid has erratic escape performance and would be unlikely to survive to breeding age. Hybrids do survive on game ranches where both species are kept and where predators are prohibited by man.

IPL
Most computer systems can only complete code found in the memory (ROM or RAM). Modern operating systems are stored on hard disks, or occasionally on Live CDs, USB flash drives, or other non-volatile storage devices. When a computer is first power-driven on, it doesn't have an operating system in memory. The computer's hardware alone cannot perform complex measures such as loading a program from disk, so an apparent paradox exists, to load the operating system into memory, one appears to need to have an operating system already loaded. The System/360 IPL function reads 24 bytes from an operator-specified or pre-configured machine into memory starting at location zero. The second and third groups of eight bytes are treated as Channel Command Words (CCWs) to maintain loading the startup program. When the I/O channel instructions are complete, the first group of eight bytes is then loaded into the Program Status Word (PSW) register and the startup program begins completing at the designated location.

Solar wind
They are directly related to the solar wind, together with geomagnetic storms that can knock out power grids on Earth, auroras and the plasma tail of a comet always pointing away from the sun. While early models of the solar wind used primarily thermal energy to accelerate the material, by the 1960s it was clear that thermal hurrying alone cannot account for the high speed solar wind. Some additional acceleration mechanism is required, but is not presently known, but most likely relates to magnetic fields in the solar atmosphere. The solar wind is answerable for the overall shape of Earth's magnetosphere, and fluctuations in its speed, density, direction, and entrained magnetic field powerfully affect Earth's local space environment.

LCD
Color components may be arrayed in a range of pixel geometries, depending on the monitor's usage. If software knows which type of geometry is being used in a given LCD, this can be used to increase the evident resolution of the monitor through subpixel rendering.

Banana
Bananas are grown in 132 countries worldwide, additional than any other fruit crop. In popular culture and commerce, banana usually refers to soft, sweet dessert bananas that are usually eaten raw. The bananas from a collection of cultivars with firmer, starchier fruit are generally used in cooking rather than eaten raw. Bananas may also be dried up and ground into banana flour. Although the wild species have fruits with numerous large, hard seeds, virtually all culinary bananas have unplanted fruits. Bananas are classified any as dessert bananas or as green cooking bananas.

Table
The data in a table does not have to be actually stored in the database. Views are also relational tables, but their data is considered at query time. In non-relational systems, such as hierarchical databases, the isolated counterpart of a table is a structured file, representing the rows of a table in each record of the file and each column in a record.

Populations
Population growth is varying in population over time. It also can be quantified as the change in the number of individuals in a population per piece time. The term population growth can technically refer to any species, but almost always refers to humans, and it often used easily for the more specific demographic term population growth rate, and is often used to refer specifically to the expansion of the population of the world.

Papaya
The primary use of the papaya is as an safe to eat fruit. The ripe fruit is generally eaten raw, without the skin or seeds. The unripe green fruit of papaya can be eaten ripe, usually in curries, salads and stews.

Coconut
Nearly all parts of the coconut palm are useful, and the palms have a comparatively high yield, it therefore has important economic value. The name for the coconut palm in Sanskrit is kalpa vriksha, which translates as the tree which provides all the requirements of life. In Malay, the coconut is known as pokok seribu guna, the tree of a thousand uses. In the Philippines, the coconut is generally given the title Tree of Life. The white, fleshy part of the seed is safe to eat and used fresh or dried in cooking.

Planet
The energetic impacts of the smaller planetesimals will heat up the increasing planet, causing it to at least partially melt. The interior of the planet begins to differentiate by mass, mounting a denser core. Smaller terrestrial planets lose most of their atmospheres because of this accretion, but the lost gases can be replaced by out gassing from the mantle and from the succeeding impact of comets.

Chemical reaction
A chemical reaction is a progression that results in the interconversion of chemical substances. The substance or substances initially involved in a chemical reaction are called reactants. Chemical reactions are characterized by a chemical change, and they yield one or more products which are, in general, unlike from the reactants. Classically, chemical reactions include changes that strictly involve the motion of electrons in the forming and breaking of chemical bonds, although the general concept of a chemical reaction, in particular the notion of a chemical equation, is applicable to transformation of elementary particles, as well as nuclear reactions. On the classical meaning, therefore, there are only two types of chemical reaction redox reactions and acid-base reaction. The former involve the motion of lone electrons and the latter of an electron pair.
Different chemical reactions are used in combinations in chemical synthesis in order to get a preferred product. In biochemistry, series of chemical reactions aided by enzymes form metabolic pathways, since straight synthesis of a product would be energetically impossible in situation within a cell. Chemical reactions are also divided into organic reactions and non-living reactions.

Honey
Honey is a sweet and thick fluid produced by honey bees from the nectar of flowers. According to the United States National Honey Board and various international food system, honey stipulates a pure product that does not allow for the addition of any other substance...this includes, but is not limited to, water or other sweeteners. This article refers exclusively to the honey produced by honey bees honey twisted by other bees or other insect have very different properties. Honey is significantly sweeter than table sugar and has attractive chemical properties for baking. Honey has a typical flavor which leads some people to prefer it over sugar and other sweeteners.
Most microorganisms do not grow in honey because of its low water movement of 0.6[2]. However, it is important to note that honey frequently contains dormant end spores of the bacteria Clostridium outline, which can be perilous to infants as the end spores can transform into toxin-producing bacteria in the infant's immature intestinal tract, leading to disease and even death. The study of pollens and spores in raw honey can determine floral sources of honey. Because bees carry an electrostatic charge, and can attract other particles, the same techniques of melissopalynology can be used in area ecological studies of radioactive particles, sand, or particulate pollution.

Partrice Luzi
Having previously played for Monaco and Ajaccio, Luzi made his Liverpool debut in January 2004 against Chelsea in a 1-0 win. He made two wonderful saves to deny Chelsea, but was left frustrated when he later was left out from the first team. His chances where limited when Liverpool loaned in Southampton's Paul Jones to cover from Jerzy Dudek and Chris Kirkland. Patrice Luzi has been described as a good shot stopper with good handling and distribution.
The SRBs are the largest solid-propellant motors ever flown and the first of such large rockets designed for reuse. Each is 149.16 feet long and 12.17 feet in diameter.

Communication
As developed below, communication happens at many levels (even for one single action), in many different ways, and for all beings, and some machines. Many or all, fields of study dedicate some attention to communication, so when speaking about communication it is very important to be sure about what kind of communication are we speaking about, mainly: what type of things are communicated, between what agents, and with what kind of results.

Language
There is no clear distinction between a language and a dialect, notwithstanding linguist Max Weinreich's famous aphorism that "a language is a dialect with an army and navy." In other words, the distinction may hinge on political considerations as much as on cultural differences, distinctive writing systems, or degree of mutual intelligibility.

Commodity
Linguistically, the word commodity came into use in English in the 15th century, being derived from the French word "commodite, meaning today's (2000) "convenience" in term of quality of services. The Latin root meaning is commoditas, referring variously to the appropriate measure of something; a fitting state, time or condition; a good quality; efficaciousness or propriety; and advantage, or benefit. The German equivalent is die Ware, i.e. wares or goods offered for sale. The French equivalent is "produit de base" like energy, goods, and industrial raw materials.

Creditor
In other words, your creditors are people to whom you owe money. The term creditor is commonly used in the financial world, particularly in orientation to short term loans, long term bonds, and mortgages. The term creditor derived from the concept of credit. In modern America, credit refers to a rating which indicates the ability of a borrower and likelihood to pay back his or her loan. In earlier times, credit also referred to reputation or trustworthiness.
