Sowing
Sowing is the process of planting seeds. An area or object that has had seeds planted in it will be described as a sowed or sown area. Plants which are usually sown Among the major field crops, oats, wheat, and rye are sown, grasses and legumes are seeded and maize and soybeans are planted. In planting, wider rows (generally 75  cm (30  in) or more) are used, and the intent is to have precise; even spacing between individual seeds in the row, various mechanisms have been devised to count out individual seeds at exact intervals. Depth of sowing In sowing, little if any soil is placed over the seeds, as seeds can be generally sown into the soil by maintaining a planting depth of about 2-3 times the size of the seed. Sowing types and patterns For hand sowing, several sowing types exist; these include: * Flat sowing * Ridge sowing * Wide bed sowing Several patterns for sowing may be used together with these types; these include: * Regular rows * Rows that are ind ...

Cloud Seeding
Cloud seeding is a type of weather modification that aims to change the amount or type of precipitation that falls from clouds by dispersing substances into the air that serve as cloud condensation or ice nuclei, which alter the microphysical processes within the cloud. Its effectiveness is debated; some studies have suggested that it is "difficult to show clearly that cloud seeding has a very large effect." The usual objective is to increase precipitation (rain or snow), either for its own sake or to prevent precipitation from occurring in days afterward. Methodologies Salts The most common chemicals used for cloud seeding include silver iodide, potassium iodide and dry ice (solid carbon dioxide). Liquid propane, which expands into a gas, has also been used. This can produce ice crystals at higher temperatures than silver iodide. After promising research, the use of hygroscopic materials, such as table salt, is becoming more popular. When cloud seeding, increased snowfall ...

Seeding (computing)
In computing, and specifically peer-to-peer file sharing, seeding is the uploading of already downloaded content for others to download from. A peer, a computer that is connected to the network, becomes a seed when having acquired the entire set of data, it begins to offer its upload bandwidth to other peers attempting to download the file. This data consists of small parts so that seeds can effectively share their content with other peers, handing out the missing pieces. A peer deliberately chooses to become a seed by leaving the upload task active once the content has downloaded. The motivation to seed is mainly to keep the file being shared in circulation (as there is no central hub to continue uploading in the absence of peer seeders) and a desire to not act as a parasite. The opposite of a seed is a leech, a peer that downloads more than they upload. Background Seeding is a practice within peer-to-peer file sharing, a content distribution model that connects computers with ...

Seeding (fluid Dynamics)
Seeding a material is a concept used in fluid dynamics to describe the act of introducing specific particulates or other foreign substances into a stream of fluid being evaluated. An altered fluid will be described as having a seeded flow. Details These particulates are generally small enough to be carried by the fluid but large enough to be picked up using a flow visualization technique, such as particle image velocimetry (PIV). In reference to aerodynamic testing, such as wind tunnel testing, water tunnel testing, or any other test investigating the flow of a fluid which may be invisible to the naked eye, seeding a flow is often the only way to take visual measurements. Simple examples of a seeded flow include the introduction of smoke into a low speed wind tunnel to see the general path of the air, or injecting colored dye into a water tunnel to see secondary flow structures such as hairpin vortices. As stated in ''The Handbook of Fluid Dynamics'', an ideal seeding pa ...

Seeding (sex Act)
A creampie (also known as internal ejaculation and, typically in same-sex contexts as a breeding) is a human sexual act, commonly featured in hardcore pornography, in which a man ejaculates inside his partner's vagina or anus without the use of a condom, resulting in visible seeping or dripping of semen from the vagina or anus. Use in pornography Internal ejaculation shots are a comparatively recent development in pornography; they are not found in early pornographic films. The use of the word ''creampie'' to describe such scenes originated in U.S. pornography in the early 2000s. In straight pornography, sexual activity is often followed by a facial, pearl necklace or other visible ejaculation. Creampie scenes depart from heterosexual pornographic convention in favor of a depiction that more closely mimics sexual activity as performed in ordinary life; they have been called the "counterimage" of facials. Depiction of creampie scenes has become a popular subgenre within hete ...

Seeding (sports)
A seed is a competitor or team in a sport or other tournament who is given a preliminary ranking for the purposes of the draw. Players/teams are "planted" into the bracket in a manner that is typically intended so that the best do not meet until later in the competition, usually based on regular season. The term was first used in tennis, and is based on the idea of laying out a tournament ladder by arranging slips of paper with the names of players on them the way seeds or seedlings are arranged in a garden: smaller plants up front, larger ones behind. Sometimes the remaining competitors in a single-elimination tournament will be "re-seeded" so that the highest surviving seed is made to play the lowest surviving seed in the next round, the second-highest plays the second-lowest, etc. This may be done after each round, or only at selected intervals. Tennis Professional tennis tournaments seed players based on their rankings. The number of seeds varies from tournament to tourname ...

Panspermia
Panspermia () is the hypothesis, first proposed in the 5th century BCE by the Greek philosopher Anaxagoras, that life exists throughout the Universe, distributed by space dust, meteoroids, asteroids, comets, and planetoids, as well as by spacecraft carrying unintended contamination by microorganisms.Forward planetary contamination like '' Tersicoccus phoenicis'', that has shown resistance to methods usually used in spacecraft assembly clean rooms: Panspermia is a fringe theory with little support amongst mainstream scientists. Critics argue that it does not answer the question of the origin of life but merely places it on another celestial body. It is also criticized because it cannot be tested experimentally. Panspermia proposes (for example) that microscopic lifeforms which can survive the effects of space (such as extremophiles) can become trapped in debris ejected into space after collisions between planets and small Solar System bodies that harbor life. Panspermia studies c ...

Seeding Machine
A seed drill is a device used in agriculture that sows seeds for crops by positioning them in the soil and burying them to a specific depth while being dragged by a tractor. This ensures that seeds will be distributed evenly. The seed drill sows the seeds at the proper seeding rate and depth, ensuring that the seeds are covered by soil. This saves them from being eaten by birds and animals, or being dried up due to exposure to the sun. With seed drill machines, seeds are distributed in rows; this allows plants to get sufficient sunlight, nutrients, and water from the soil. Before the introduction of the seed drill, most seeds were planted by hand broadcasting, an imprecise and wasteful process with a poor distribution of seeds and low productivity. Use of a seed drill can improve the ratio of crop yield (seeds harvested per seed planted) by as much as nine times. The use of seed drill saves time and labor. Some machines for metering out seeds for planting are called planters. ...

Seeding Trial
A seeding trial or marketing trial is a form of marketing, conducted in the name of research, designed to target product sampling towards selected consumers. In the marketing research field, seeding is the process of allocating marketing to specific customers, or groups of customers, in order to stimulate the internal dynamics of the market, and enhance the diffusion process. In medicine, seeding trials are clinical trials or research studies in which the primary objective is to introduce the concept of a particular medical intervention—such as a pharmaceutical drug or medical device—to physicians, rather than to test a scientific hypothesis. To create loyalty and advocacy towards a brand, seeding trials take advantage of opinion leadership to enhance sales, capitalizing on the Hawthorne Effect. In a seeding trial, the brand provides potential opinion leaders with the product for free, aiming to gain valuable pre-market feedback and also to build support among the testers, creati ...
