Tacks Latimer
Clifford Wesley "Tacks" Latimer (November 30, 1875 – April 24, 1936) was an American professional baseball catcher who played in Major League Baseball for the New York Giants (NL), New York Giants, Louisville Colonels, Pittsburgh Pirates, Baltimore Orioles (1901–1902), Baltimore Orioles, and Brooklyn Superbas from 1898 to 1902. Including the years he played only in the Minor League Baseball, minor leagues or as a semi-professional sports, semi-professional, Latimer's career ranged from 1895 to 1908. After his playing career ended, Latimer became a police officer with the Pennsylvania Railroad. In 1924, after a dispute with another police officer, Latimer shot him four times in the back, killing him. Latimer was found guilty of second-degree murder and sentenced to life imprisonment. He received a pardon in 1930 for his heroism during a prison break. Early life Clifford Wesley Lattimer was born in Loveland, Ohio, on November 30, 1875, to John Wesley and Nora (née McAda ...

Tack Weld
Thermoproteati is a kingdom of archaea. Its synonym, "TACK", is an acronym for Thaumarchaeota (now Nitrososphaerota), Aigarchaeota, Crenarchaeota (now Thermoproteota), and Korarchaeota (now Thermoproteota), the first groups discovered. They are found in different environments ranging from acidophilic thermophiles to mesophiles and psychrophiles and with different types of metabolism, predominantly anaerobic and chemosynthetic. Thermoproteati is a kingdom that is sister to the Asgard branch that gave rise to the eukaryotes. It has been proposed that the Thermoproteati kingdom be classified as "Crenarchaeota" and that the traditional "Crenarchaeota" (Thermoproteota) be classified as a class called "Sulfolobia", along with the other phyla with class rank or order. After including the kingdom category into ICNP, the only validly published name of this group is kingdom Thermoproteati (Guy and Ettema 2024). Classification * Thermoproteota (formerly "Crenarchaeota"). It is the bes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grand Tack Hypothesis
In planetary astronomy, the grand tack hypothesis proposes that Jupiter formed at a distance of 3.5 AU from the Sun, then migrated inward to 1.5 AU, before reversing course due to capturing Saturn in an orbital resonance, eventually halting near its current orbit at 5.2 AU. The reversal of Jupiter's planetary migration is likened to the path of a sailboat changing directions ( tacking) as it travels against the wind. The planetesimal disk is truncated at 1.0 AU by Jupiter's migration, limiting the material available to form Mars. Jupiter twice crosses the asteroid belt, scattering asteroids outward then inward. The resulting asteroid belt has a small mass, a wide range of inclinations and eccentricities, and a population originating from both inside and outside Jupiter's original orbit. Debris produced by collisions among planetesimals swept ahead of Jupiter may have driven an early generation of planets into the Sun. Description In the ''grand tack hypothesis'' Jupiter underwen ...

Tackers
Tackers was the name given to High Tory Members of Parliament who in 1704 tried to attach ('tack') an Occasional Conformity Act 1711, Occasional Conformity Bill to money bills in order to pass it through the House of Lords and into law. The Tackers ultimately failed in their efforts, but their actions proved highly polarising in the 1705 English general election. While there were some successful Whigs (British political party), Whig campaigns to unseat Tacker MPs, some parts of the country had the Tories (British political party), Tories successfully campaign under the rallying cry of 'Church in Danger', with the Tackers' efforts being positively seen as an effort to protect the established Church of England from Nonconformist (Protestantism), nonconformists and Dissent. The Tackers' actions caused Anne, Queen of Great Britain, Queen Anne to turn away from their party as the War of Spanish Succession continued for the next decade. Instead, she added more Whigs to her government, le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adhesion
Adhesion is the tendency of dissimilar particles or interface (matter), surfaces to cling to one another. (Cohesion (chemistry), Cohesion refers to the tendency of similar or identical particles and surfaces to cling to one another.) The forces that cause adhesion and cohesion can be divided into several types. The intermolecular forces responsible for the function of various kinds of stickers and sticky tape fall into the categories of chemical adhesion, dispersive adhesion, and diffusive adhesion. In addition to the cumulative magnitudes of these intermolecular forces, there are also certain emergent mechanical effects. Surface energy Surface energy is conventionally defined as the work (physics), work that is required to build an area of a particular surface. Another way to view the surface energy is to relate it to the work required to cleave a bulk sample, creating two surfaces. If the new surfaces are identical, the surface energy γ of each surface is equal to h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tacksman
A tacksman (, meaning "supporting man"; most common Scots spelling: ''takisman'') was a landholder of intermediate legal and social status in Scottish Highland society. Tenant and landlord Although a tacksman generally paid a yearly rent for the land let to him (his "tack"), his tenure might last for several generations. He would often be related to his landlord and might, for example, represent a cadet branch of the family of the clan chief. The tacksman in turn would let out his land to sub-tenants, but he might keep some in hand himself. Dr Johnson defined the class in this manner: The three fundamental obligations traditionally imposed on tacksmen were grassum (a premium payable on entering into a lease), rental (either in kind, or in money, which was designated "tack-duty"), and the rendering of military service.Alexander Nicholson, ''History of Skye'' (3rd edition, Islands Book Trust, 2012), at pages 127 to 128.

Hardtack
Hardtack (or hard tack) is a type of dense Cracker (food), cracker made from flour, water, and sometimes salt. Hardtack is inexpensive and long-lasting. It is used for sustenance in the absence of perishable foods, commonly during long sea voyages, land migrations, and military campaigns. Along with salt pork and corned beef, hardtack was a Field ration, standard ration for many militaries and navies from the 17th to the early 20th centuries. Etymology The name is derived from "tack", the British sailor slang for food. The earliest use of the term recorded by the ''Oxford English Dictionary'' is from 1830. It is known by other names including ''brewis'' (possibly a cognate with "brose"), ''cabin bread'', ''pilot bread'', ''sea biscuit'', ''soda crackers'', ''sea bread'' (as rations for sailors), ''ship's biscuit'', and pejoratively as ''Dog biscuit, dog biscuits'', ''Molar (tooth), molar breakers'', ''sheet iron'', ''tooth dullers'', ''Panzerplatten'' ("''armor plates''"; Germany ...

Tack (square Sail)
The tack of a square-rigged sail is a line attached to its lower corner. This is in contrast to the more common fore-and-aft sail, whose tack is a part of the sail itself, the corner which is (possibly semi-permanently) secured to the vessel. Most square-rig sails have their clews pulled down to the yard of the sail below, and hence the position of the foot of the sail is controlled by the braces of the sail below. These sails do not have tacks. The exception to this scheme is the course, which does not have a yard below it. On this sail, the sheets are led aft, and pull the clews back as well as down, taking the place of the braces of the non-existent sail below. This works perfectly well when the wind is aft of the beam, but as the ship heads further to windward the sheets become less and less effective for controlling the windward clew. Rather than being a simple "bag of wind" held from behind, the sail must be pulled into a (fairly poor) approximation of an aerofoil, like a ...

Tack (sailing)
A tack is the windward side of a sailing craft (side from which the wind is coming while under way)—the starboard or port tack. Generally, a craft is on a starboard tack if the wind is coming over the starboard (right) side with sails on port (left) side. Similarly, a craft is on a port tack if the wind is coming over the port (left). Tack is also a nautical term both for the lower, windward corner of a sail. Windward side of course sailed As a point of reference, tack is the alignment of the wind with respect to a sailing craft under way. If the wind is from the starboard side of the sailing craft, it is on ''starboard tack'', and if from port, on ''port tack''. The International Regulations for Preventing Collisions at Sea for vessels underway declare that when the courses of two sailing vessels converge, the vessel on ''port tack'' must give way to a vessel on ''starboard tack''. The maneuver of changing a sailing craft's course from one tack to the other during which t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tacking (sailing)
Tacking or coming about is a sailing maneuver by which a sailing craft ( sailing vessel, ice boat, or land yacht), whose next destination is into the wind, turns its bow toward and through the wind so that the direction from which the wind blows changes from one side of the boat to the other, allowing progress in the desired direction. Sailing vessels are unable to sail higher than a certain angle towards the wind, so "beating to windward" in a zig-zag fashion with a series of tacking maneuvers, allows a vessel to sail towards a destination that is closer to the wind than the vessel can sail directly. A sailing craft whose course is downwind jibes (or "wears" if square-rigged) by having the apparent wind cross the stern from one tack to the other. High-performance sailing craft may tack, rather than jibe, downwind, when the apparent wind is well forward. Beating to windward Sails are limited in how close to the direction of the wind they can power a sailing craft. The ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drawing Pin
A drawing pin (in British English) or thumb tack (in North American English), also called a push-pin, is a short, small pin or nail with a flat, broad head that can be pressed into place with pressure from the thumb, often used for hanging light articles on a wall or noticeboard. Thumb tacks made of brass, tin or iron may be referred to as brass tacks, brass pins, tin tacks or iron tacks, respectively. These terms are particularly used in the idiomatic expression ''to come'' (or ''get'') ''down to brass'' (or otherwise) ''tacks'', meaning to consider basic facts of a situation. History The drawing pin was invented in name and first mass-produced in what is now the United States in the mid/late 1750s; the earliest use of the term "drawing pin" is listed in the Oxford English Dictionary as 1812. It was said that the use of the newly invented drawing pin to attach notices to school house doors was making significant contribution to the whittling away of their gothic doors ...

Robustness
Robustness is the property of being strong and healthy in constitution. When it is transposed into a system A system is a group of interacting or interrelated elements that act according to a set of rules to form a unified whole. A system, surrounded and influenced by its open system (systems theory), environment, is described by its boundaries, str ..., it refers to the ability of tolerating perturbations that might affect the system's functional body. In the same line ''robustness'' can be defined as "the ability of a system to resist change without adapting its initial stable configuration". "Robustness in the small" refers to situations wherein perturbations are small in magnitude, which considers that the "small" magnitude hypothesis can be difficult to verify because "small" or "large" depends on the specific problem. Conversely, "Robustness in the large problem" refers to situations wherein no assumptions can be made about the magnitude of perturbations, which can eit ...
