Tenacity (mineralogy)
In mineralogy, tenacity is a mineral's behavior when deformed or broken. Common terms Brittleness: The mineral breaks or powders easily. Most ionic-bonded minerals are brittle. Malleability: The mineral may be pounded out into thin sheets. Metallic-bonded minerals are usually malleable. Ductility: The mineral may be drawn into a wire. Ductile materials have to be malleable as well as tough. Sectility: May be cut smoothly with a knife. Relatively few minerals are sectile. Sectility is a form of tenacity and can be used to distinguish minerals of similar appearance. Gold, for example, is sectile but pyrite The mineral pyrite (), or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula Fe S2 (iron (II) disulfide). Pyrite is the most abundant sulfide mineral. Pyrite's metallic luster and pale brass-yellow hue giv ... ("fool's gold") is not. Elasticity: If bent, will spring back to its original position when the stress is released. P ...

Mesotrione
Mesotrione is the ISO common name for an organic compound that is used as a selective herbicide, especially in maize. A synthetic inspired by the natural substance leptospermone, it inhibits the enzyme 4-hydroxyphenylpyruvate dioxygenase (HPPD) and is sold under brand names including Callisto and Tenacity. It was first marketed by Syngenta in 2001. History The invention of the triketone class of herbicides had its beginnings in an observation in 1977 of allelopathic weed control near a bottlebrush tree, '' Callistemon citrinus''. Chemists at the Stauffer Chemical Company identified the compound responsible as leptospermone, a known natural product which had not previously been reported as having biological activity. Extensive work on analogues led to the discovery and development of sulcotrione and mesotrione. The triketone herbicides were found to be effective on a wide range of commercially-important weed species and to have both pre- and post-emergence activity. M ...

Tenacity (textile Strength)
The specific strength is a material's (or muscle's) strength (force per unit area at failure) divided by its density. It is also known as the strength-to-weight ratio or strength/weight ratio or strength-to-mass ratio. In fiber or textile applications, tenacity is the usual measure of specific strength. The SI unit for specific strength is Pa⋅ m3/ kg, or N⋅m/kg, which is dimensionally equivalent to m2/s2, though the latter form is rarely used. Specific strength has the same units as specific energy, and is related to the maximum specific energy of rotation that an object can have without flying apart due to centrifugal force. Another way to describe specific strength is breaking length, also known as self support length: the maximum length of a vertical column of the material (assuming a fixed cross-section) that could suspend its own weight when supported only at the top. For this measurement, the definition of weight is the force of gravity at the Earth's surface ( st ...

Audacity (audio Editor)
Audacity is a free and open-source digital audio editor and recording application software, available for Windows, macOS, Linux, and other Unix-like operating systems. The project was started in the fall of 1999 by Dominic Mazzoni and Roger Dannenberg at Carnegie Mellon University, and released on May 28, 2000, as version 0.8. As of September 22, 2022, Audacity is the most popular download at FossHub, with over 114.1 million downloads since March 2015. It was previously served from Google Code and SourceForge, where it was downloaded over 200 million times. Audacity won the SourceForge 2007 and 2009 Community Choice Award for Best Project for Multimedia. It is licensed under GPL-2.0-or-later. In 2019, then-lead developer James Crook started the fork ''DarkAudacity'' to experiment with a new look and other UX changes. Most of its changes were eventually incorporated into the mainline version and the fork ended. In April 2021, it was announced that Muse Group (owners of Mu ...

Dream Chaser Tenacity
Dream Chaser ''Tenacity'' is the first Dream Chaser spacecraft expected to fly in space. Manufactured by the Sierra Nevada Corporation, it will first fly to the International Space Station as part of the SNC Demo-1 mission in 2023, under the CRS-2 contract. Background The Sierra Nevada Corporation was awarded a CRS-2 contract for by NASA for six operational resupply spaceflights to the International Space Station. SNC Demo-1 is a demo flight that will precede the operational resupply flights if the mission is successful. ''Tenacity'' and other Dream Chasers will be mated with a Shooting Star module, which will provide an additional of payload capacity, in addition to the carried by the spaceplane. The module will be separated from the Dream Chaser prior to reentry and burn up in the atmosphere, while the Dream Chaser vehicle will perform a runway landing to be reused. As of 2022, ''Tenacity'' is still under development. Overall, the spacecraft's structure is largely c ...

Tenacity On The Tasman
''Tenacity on the Tasman'' is a 2009 documentary film about adventurer Olly Hicks's attempt to circumnavigate the world in a rowboat. The film premiered at the ODEON Leicester Square on November 19, 2009, becoming the first independently distributed documentary to premiere at the theater. The film was produced and directed by independent filmmaker George Olver through his production company Pendragon Productions, and distributed globally as part of the Adventure Film Festival. Synopsis He was the first person to row across the Atlantic from New York to the Europe. However five previous trans-Atlantic rowers had gone from the United States to France, some in about half the time it took Hicks. Two of the five rowed a greater distance. He was at the time the youngest person ever to row an ocean at 23, Since then Katie Spotz, a 22-year-old American rower has completed the journey. Olly Hicks sets in motion a plan to row solo around the world. While shooting a Virgin advertisem ...
