For the first time they were predicted to occur in deformed atomic nuclei by N. LoIudice and F. Palumbo, [ 1 ] who used a semiclassical Two Rotor Model, whose solution required a realization... | https://en.wikipedia.org/wiki/Scissors_Modes |
Scitex Continuous Tone or Scitex CT is an image file format . It is designed specifically for use on Scitex graphics processing equipment. [ 1 ] Its use is supported by numerous graphics suites and desktop publishing packages, such as Adobe Photoshop , [ 2 ] Adobe InDesign , [ 1 ] and QuarkXPress .
The Scitex CT forma... | https://en.wikipedia.org/wiki/Scitex_CT |
The scleraxis protein is a member of the basic helix-loop-helix (bHLH) superfamily of transcription factors . [ 1 ] Currently two genes ( SCXA and SCXB respectively) have been identified to code for identical scleraxis proteins.
It is thought that early scleraxis-expressing progenitor cells lead to the eventual format... | https://en.wikipedia.org/wiki/Scleraxis |
Sclerobionts are collectively known as organisms living in or on any kind of hard substrate (Taylor and Wilson, 2003). A few examples of sclerobionts include Entobia borings, Gastrochaenolites borings, Talpina borings, serpulids , encrusting oysters , encrusting foraminiferans , Stomatopora bryozoans , and “Berenicea” ... | https://en.wikipedia.org/wiki/Sclerobiont |
The sclerometer , also known as the Turner-sclerometer (from Ancient Greek : σκληρός meaning "hard"), is an instrument used by metallurgists , material scientists and mineralogists to measure the scratch hardness of materials. It was invented in 1896 by Thomas Turner (1861–1951), the first Professor of metallurgy in Br... | https://en.wikipedia.org/wiki/Sclerometer |
A mechanical system is scleronomous if the equations of constraints do not contain the time as an explicit variable and the equation of constraints can be described by generalized coordinates. Such constraints are called scleronomic constraints. The opposite of scleronomous is rheonomous .
In 3-D space, a particle wit... | https://en.wikipedia.org/wiki/Scleronomous |
Sclerophyll is a type of vegetation that is adapted to long periods of dryness and heat. The plants feature hard leaves , short internodes (the distance between leaves along the stem) and leaf orientation which is parallel or oblique to direct sunlight.
Sclerophyllous plants occur in many parts of the world, [ 1 ] but... | https://en.wikipedia.org/wiki/Sclerophyll |
A scleroscope is a device used to measure rebound hardness . It consists of a steel ball dropped from a fixed height. The device was invented in 1907. As an improvement on this rough method, the Leeb Rebound Hardness Test , invented in the 1970s, uses the ratio of impact and rebound velocities (as measured by a magn... | https://en.wikipedia.org/wiki/Scleroscope |
Sclerotiorin is an antimicrobial Penicillium frequentans isolate. Sclerotiorin is an aldose reductase inhibitor ( IC 50 =0.4 μM) as well as a reversible lipoxygenase inhibitor ( IC 50 =4.2 μM). [ 1 ] [ 2 ]
