Seafloor Spreading
Seafloor spreading or Seafloor spread is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge. History of study Earlier theories by Alfred Wegener and Alexander du Toit of continental drift postulated that continents in motion "plowed" through the fixed and immovable seafloor. The idea that the seafloor itself moves and also carries the continents with it as it spreads from a central rift axis was proposed by Harold Hammond Hess from Princeton University and Robert Dietz of the U.S. Naval Electronics Laboratory in San Diego in the 1960s. The phenomenon is known today as plate tectonics. In locations where two plates move apart, at mid-ocean ridges, new seafloor is continually formed during seafloor spreading. Significance Seafloor spreading helps explain continental drift in the theory of plate tectonics. When oceanic plates diverge, tensional stress causes fractures to occu ...

Wetting
Wetting is the ability of a liquid to maintain contact with a solid surface, resulting from intermolecular interactions when the two are brought together. This happens in presence of a gaseous phase or another liquid phase not miscible with the first one. The degree of wetting (wettability) is determined by a force balance between adhesive and cohesive forces. Wetting is important in the bonding or adherence of two materials. Wetting and the surface forces that control wetting are also responsible for other related effects, including capillary effects. There are two types of wetting: non-reactive wetting and reactive wetting. Wetting deals with three phases of matter: gas, liquid, and solid. It is now a center of attention in nanotechnology and nanoscience studies due to the advent of many nanomaterials in the past two decades (e.g. graphene, Carbon nano tube, carbon nanotube, boron nitride nanomesh). Explanation Adhesive forces between a liquid and solid cause a liq ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spread Offense
:''"Spread offense" may also refer to the four corners offense in basketball.'' The spread offense is an offensive scheme in gridiron football that typically places the quarterback in the shotgun formation, and "spreads" the defense horizontally using three-, four-, and even five-receiver sets. Used at every level of the game including professional (NFL, CFL), college (NCAA, NAIA, CIS), and high school programs across the US and Canada, spread offenses often employ a no-huddle approach. Some implementations of the spread also feature wide splits between the offensive linemen. Spread offenses can emphasize the pass or the run, with the common attribute that they force the defense to cover the entire field from sideline to sideline. Many spread teams use the read option running play to put pressure on both sides of the defense. Similar to the run and shoot offense, passing-oriented spread offenses often leverage vertical (down field) passing routes to spread the defense v ...

Spreading (debate)
Spreading is the act of speaking extremely fast during a competitive debating event, with the intent that one's opponent will be penalized for failing to respond to all arguments raised. It is a portmanteau of "speed" and "reading". The tactic relies on the fact that "failing to answer all opposing arguments" is an easy criterion for judges to award a win on, and that speaking fast and fielding an overwhelming number of distinct arguments can be a viable strategy. Spreading dominated the US school debate circuit in the 1990s. In the early 2000s, the style itself became a topic of many debates, with some arguing that it was exclusionary and possibly discriminatory, as it focused on speaking fast rather than being impassioned about a subject, and some educational companies began selling debate prep materials to assist those employing the style in packing as many topics as possible into their arguments, creating an advantage for those with more money. The public forum debate format w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spread Spectrum
In telecommunication and radio communication, spread-spectrum techniques are methods by which a signal (e.g., an electrical, electromagnetic, or acoustic signal) generated with a particular bandwidth is deliberately spread in the frequency domain, resulting in a signal with a wider bandwidth. These techniques are used for a variety of reasons, including the establishment of secure communications, increasing resistance to natural interference, noise, and jamming, to prevent detection, to limit power flux density (e.g., in satellite downlinks), and to enable multiple-access communications. Telecommunications Spread spectrum generally makes use of a sequential noise-like signal structure to spread the normally narrowband information signal over a relatively wideband (radio) band of frequencies. The receiver correlates the received signals to retrieve the original information signal. Originally there were two motivations: either to resist enemy efforts to jam the communication ...

Policy Debate
Policy debate is an American form of debate competition in which teams of two usually advocate for and against a resolution that typically calls for policy change by the United States federal government. It is also referred to as cross-examination debate (sometimes shortened to Cross-X or CX) because of the 3-minute questioning period following each constructive speech. Evidence presentation is a crucial part of Policy Debate. The main argument being debated during a round of Policy is which team wins a system by which the debate should be evaluated (Framework) and who wins under this framework (gets the ballot). When a team explains why their impacts are "greater" than the opposition's impacts, they utilize the concept of "impact calculus." One team’s job is to argue that the resolution— the statement that we should make some specific change to address a national or international problem —is a good idea. Affirmative teams generally present a ''plan'' as a proposal for imple ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Statistical Dispersion
In statistics, dispersion (also called variability, scatter, or spread) is the extent to which a distribution is stretched or squeezed. Common examples of measures of statistical dispersion are the variance, standard deviation, and interquartile range. For instance, when the variance of data in a set is large, the data is widely scattered. On the other hand, when the variance is small, the data in the set is clustered. Dispersion is contrasted with location or central tendency, and together they are the most used properties of distributions. Measures A measure of statistical dispersion is a nonnegative real number that is zero if all the data are the same and increases as the data become more diverse. Most measures of dispersion have the same units as the quantity being measured. In other words, if the measurements are in metres or seconds, so is the measure of dispersion. Examples of dispersion measures include: * Standard deviation * Interquartile range (IQR) * Range * ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
$pread
''$pread'' was a quarterly magazine by and for sex workers and those who support their rights. The magazine's focus was: "personal experiences and political insights" and it "contain(ed) practical information like news, features, health columns, and resources related to the sex industry". History Articles were written by readers as well as by figures from academic, cultural, and literary backgrounds, most of whom were current or former sex workers. The magazine was launched on March 15, 2005 by Rachel Aimee, Rebecca Lynn, and Raven Strega. ''$pread'' was based in New York City, and was sold throughout the United States and Canada at independent bookstores and via national distributors. A co-editor said, "We want the general public to become aware of issues such as the physical working conditions of sex workers and their health care and housing needs, and to start considering sex workers as real people rather than mythical beasts who only come to life when someone drops a quarter ...

Tarot
The tarot (, first known as '' trionfi'' and later as ''tarocchi'' or ''tarocks'') is a pack of playing cards, used from at least the mid-15th century in various parts of Europe to play card games such as Tarocchini. From their Italian roots, tarot playing cards spread to most of Europe evolving into a family of games that includes German Grosstarok and more recent games such as French Tarot and Austrian Königrufen which are still played today. In the late 18th century, French occultists began to make elaborate, but unsubstantiated, claims about their history and meaning, leading to the emergence of custom decks for use in divination via tarot card reading and cartomancy. Thus there are two distinct types of tarot pack: those used for playing games and those used for divination. However, some older patterns, such as the Tarot de Marseille, originally intended for playing card games, have also been used for cartomancy. Like the common playing cards, tarot has four sui ...

Bedspread
Bedding, also known as bedclothes or bed linen, is the materials laid above the mattress of a bed for hygiene, warmth, protection of the mattress, and decorative effect. Bedding is the removable and washable portion of a human sleeping environment. Multiple sets of bedding for each bed are often washed in rotation and/or changed seasonally to improve sleep comfort at varying room temperatures. Most standardized measurements for bedding are rectangular, but there are also some square-shaped sizes, which allows the user to put on bedding without having to consider its lengthwise orientation (e.g. a duvet). In American English, the word ''bedding'' generally does not include the mattress, bed frame, or bed base (such as box-spring), while in British English it does. In Australian and New Zealand English, bedding is often called ''manchester'', especially in shops. Manchester was a center of the cotton industry in the late 18th and the 19th century, and into the 20th century, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spread (food)
A spread is a food that is spread, generally with a knife, onto foods such as bread and crackers. Spreads are added to food to enhance the flavor or texture of the food, which may be considered bland without it. Butter and soft cheeses are typical spreads. A sandwich spread is a spreadable condiment used in a sandwich, in addition to more solid ingredients. Butter, mayonnaise, prepared mustard, and ketchup are typical sandwich spreads, along with their variants such as Thousand Island dressing, Tartar sauce, and Russian dressing. Spreads are different from dips, such as salsa, which are generally not applied to spread onto food, but have food dipped into them, instead. Common spreads include dairy spreads (such as cheeses, creams, and butters, although the term "butter" is broadly applied to many spreads), margarines, honey, plant-derived spreads (such as jams, jellies, and hummus), yeast spreads (such as vegemite and marmite), and meat-based spreads (such as '' p� ...
