The ability to modify the hardness of steel by heat treatment had been known since 1100 BC, and the rare material was valued for use in tool and weapon making.

In physics and optics, the Abbe number, also known as the V-number or constringence of a transparent material, is a measure of the material's dispersion ( variation of refractive index with wavelength ) in relation to the refractive index, with high values of V indicating low dispersion ( low chromatic aberration ).

He wrote three books on chess strategy: Mein System ( My System ), 1925, Die Praxis meines Systems ( The Practice of My System ), 1929, commonly known as Chess Praxis, and Die Blockade ( The Blockade ), 1925, though much in the latter book is generally held to be a rehash of material already presented in Mein System.

* Game piece ( gamepiece, counter, token, bit, meeple, mover, pawn, man, playing piece, player piece )— a player's representative on the gameboard made of a piece of material made to look like a known object ( such as a scale model of a person, animal, or inanimate object ) or otherwise general symbol.

By controlling the pressure and temperature applied to phenol and formaldehyde, he produced a hard moldable material and patented in 1907 known as Bakelite.

Granite boulders were also taken from the moor and used for stone posts and to a certain extent for building ( such material is known as moorstone ).

When BSE material infects humans, the resulting disease is known as ( new ) variant CJD ( nvCJD ).

This forms another material known as slaked lime ( Ca ( OH )< sub > 2 </ sub >), which is an inexpensive base material used throughout the chemical industry.

The material derivative is also known as the substantial derivative, or comoving derivative, or convective derivative.

If later heat treatments cause this glass to become partly crystalline, the resulting material is known as a glass-ceramic, widely used as cooktop.

By estimating both the clay and temper compositions, and locating a region where both are known to occur an assignment of the material source can be made.

The Gnome Press edition ( 1950 – 1957 ) was the first hardcover collection of Howard's Conan stories, including all the original Howard material known to exist at the time, some left unpublished in his lifetime.

The most well known version is that written by Gerald Gardner, and includes material paraphrased works by Aleister Crowley, primarily from Liber ALThe Book of the Law ( particularly from Ch 1, spoken by Nuit, the Star Goddess ), and from his Liber XV: the Gnostic Mass as well as Liber LXV ( Liber Cordis Cincti Serpente, or the Book of the Heart Girt with the Serpent ), thus linking modern Wicca irrevocably to the cosmology and revelations of Thelema.

Calorimetry requires that the material being heated have known definite thermal constitutive properties.

This assumption is related to, but is not the same as, the above used assumption that the pressure of the body of calorimetric material is known as a function of its volume and temperature ; anomalous behaviour of materials can affect this relation.

An associated pair of centrioles, arranged perpendicularly and surrounded by an amorphous mass of dense material ( the pericentriolar material ) constitutes the compound structure known as the centrosome.

Terfenol-D has the highest room-temperature magnetostriction of any known material ; this property is employed in transducers, wide-band mechanical resonators, and high-precision liquid fuel injectors.

** Dennis the Menace Annual, now known as the Dennis and Gnasher Annual, a compilation of the comics plus new material

At the moment, it is not known how the material is produced or if it remains stable without applied pressure, however, there is conjecture that it is possible to produce a new stable state of matter by compressing ultracold deuterium in a Rydberg state.

In Russia, chronicles record the use of a material known as bulat steel to make highly valued weapons, including swords, knives and axes.

Pernambuco, also known as Brazilwood, is regarded as an excellent quality stick material, but due to its scarcity and expense, other materials are increasingly being used.

He had belonged to this land and, perhaps, had desecrated it -- and this was the only material symbol that remained of him.

How lightly her `` eventshah-leh '' passed into the crannies where I was storing dialect material for some vaguely dreamed opus, and how the word would echo.

Everything was burnished with sweat and grease so that all of the objects seemed to have been carved from the same material and to be ageless.

When he heard that Paul Whiteman was looking for singers to replace the Rhythm Boys, Mercer applied and got the job, `` not for my voice, I'm sure, but because I could write songs and material generally ''.

At a recent meeting of the Women's Association of the Trumbull Ave. United Presbyterian Church, considerable use was made of material from The Detroit News on the King James version of the New Testament versus the New English Bible.

The anode material was porous graphite.

Although the tape was run for over 1 hr., a steady state was not reached, and it was concluded that the reason for this was that the back pressure of the manometer was built up from the material fed from between the blocks and this was available at a very slow rate.

A back pressure was then introduced, and the rise or fall of the material in the manometer indicated which was greater, the normal pressure in the block or the back pressure.

Dr. Douglass was kind enough to lend us about 5 grams of his material.

The x-ray diffraction pattern of the material, taken with CuK**ya radiation, indicated the presence of no extra lines and was in good agreement with the pattern of Douglass.

The small amount of insoluble material which precipitated during dialysis was suspended in approximately 5 ml of starting buffer, centrifuged, resuspended in 2.5 ml of isotonic saline and tested for antibody activity.

The firm red spleen weighed 410 gm., and its surface was mottled by discrete, small patches of white material.

The small intestine and colon contained approximately 300 cc. of foul-smelling, sanguineous material, and the mucosa throughout was hyperemic and mottled green-brown.

Each was told to purchase material if he felt like it.

Costaggini said it was Brumidi's fault in not providing enough material to fill the circle.

In vinyl foam, the big news was the development of techniques for coating fabrics with the material ( for details, see P. 395 ).

The closed molding of flexible urethane foams has been a problem ever since the introduction of the material ( molding in open molds was more feasible ).

Diane was needed as a material witness in the case and New York police searched three continents before they found her in their own back yard -- in a swank hotel, of course.

It was when she was seized as a material witness that she got the designation she liked best.
