* Hypoglycaemia ( Chromium deficiency )

Chromium ( ) is a chemical element which has the symbol Cr and atomic number 24.

Chromium is remarkable for its magnetic properties: it is the only elemental solid which shows antiferromagnetic ordering at room temperature ( and below ).

Chromium metal left standing in air is passivated by oxygen, forming a thin protective oxide surface layer.

Chromium is the 24th most abundant element in Earth's crust with an average concentration of 100 ppm.

Chromium is mined as chromite ( FeCr < sub > 2 </ sub > O < sub > 4 </ sub >) ore. About two-fifths of the chromite ores and concentrates in the world are produced in South Africa, while Kazakhstan, India, Russia, and Turkey are also substantial producers.

A beta version of this plugin is also available for Google Chrome and Chromium.

Stainless steel is defined as a regular steel alloy with greater than 10 % by weight alloying content of Chromium.

Chromium impurities in corundum yield a red tint, and the resultant gemstone is called a ruby.

For example, one species of chromium, known as Chromium III or Trivalent Chromium, is needed by the body and causes no ill effects ; however, Chromium VI or Hexavalent Chromium, is very toxic to the body.

Chromium iron is a commonly used material, which gives an efficiency of about 1 % over a wide range of energies.

Chromium is added in small amounts to the ladle to reduce free graphite, produce chill, and because it is a powerful carbide stabilizer ; nickel is often added in conjunction.

The difference is consistent with cross-linking by polychromium species, of the sort arising from olation and oxolation. Possible Chromium ( III ) Tanning Mechanisms

In acid solution the unstable blue peroxo complex Chromium ( VI ) oxide peroxide, CrO ( O < sub > 2 </ sub >)< sub > 2 </ sub >, is formed ; it is an uncharged covalent molecule which may be extracted into ether.

Chromium oxide was used by the Chinese in the Qin dynasty over 2, 000 years ago to coat weapons such as bronze crossbow bolts and steel swords found at the Terracotta Army.

Frimy and Auguste Verneuil manufactured artificial ruby by fusing BaF < sub > 2 </ sub > and Al < sub > 2 </ sub > O < sub > 3 </ sub > with a little Chromium at red heat.

Chromium ( III ) sulfate dissolves to give the hexaaquachromium ( III ) cation, < sup > 3 +</ sup >, which at higher pH undergoes processes called olation to give polychromium ( III ) compounds that are active in tanning, being the cross-linking of the collagen subunits.

* Marvel vs Wildstorms Chromium character cards-8 character cards, being 5 new ( Black King, Brass, Crystal, Team X and Wynonna Earp ) and 3 variant characters, randomly inserted in packs of Marvel vs Wildstorms Trading Cards, released Summer 1997, at the rate of 1 per 7 packs.

Chromium analysis gave 58.8% Cr as compared with 61.2% theory.

Chromium was regarded with great interest because of its high corrosion resistance and hardness.

Chromium and ferrochromium are produced from the single commercially viable ore, chromite, by silicothermic or aluminothermic reaction or by roasting and leaching processes.

Chromium metal treated in this way readily dissolves in weak acids.

Chromium, unlike metals such as iron and nickel, does not suffer from hydrogen embrittlement.

Chromium compounds are found in the environment, due to erosion of chromium-containing rocks and can be distributed by volcanic eruptions.

Chromium isotopic contents are typically combined with manganese isotopic contents and have found application in isotope geology.

Chromium has no verified biological role and has been classified as not essential for mammals.

Chromium salts ( chromates ) are also the cause of allergic reactions in some people.

Chromium, which had sold for $ 3. 90 a pound in 1980, was down to $ 3. 70 in 1990.

Other solutions support parallel OpenGL programs for Virtual Reality, scalability or graphics clusters usage, either transparently like Chromium or through a programming interface like Equalizer.

Chromium salts can also be used to impart moderate anti-stick properties.

If the deficiency persists long enough, it is reasonable to suppose that the Af label will reflect the Af distribution in the thyroglobulin.

this is really a deficiency in the scalar field, namely, that it is not algebraically closed.

This is clearly a deficiency in T.

In West Africa, for example, where meat is a luxury and babies must be weaned early to make room at the breast for later arrivals, a childhood menace is kwashiorkor, or `` Red Johnny '', a growth-stunting protein deficiency ( signs: reddish hair, bloated belly ) that kills more than half its victims, leaves the rest prey for parasites and lingering tropical disease.

An atom containing an equal number of protons and electrons is electrically neutral, otherwise it has a positive charge if there are fewer electrons ( electron deficiency ) or negative charge if there are more electrons ( electron excess ).

"... Baeyer is an excellent experimentor, but he is only an empiricist, lacking sense and capability, and his interpretations of his experiments show particular deficiency in his familiarity with the principles of true science ..."

Common competition policy is also helpful to avoid competition deficiency.

Cretinism is a condition of severely stunted physical and mental growth due to untreated congenital deficiency of thyroid hormones ( congenital hypothyroidism ) usually due to maternal hypothyroidism.

Dyslexia is distinct from reading difficulties resulting from other causes, such as a non-neurological deficiency with vision or hearing, or from poor or inadequate reading instruction.

For instance, 30 % of the world's population either has, or is at risk for developing, iodine deficiency.

It is estimated that at least 3 million children are blind due to vitamin A deficiency.

If total cash available is less than cash needs, a deficiency exists.

The Edelman algorithm works equally well for sparse and non-sparse data, since it is based on the compressibility ( rank deficiency ) of the Fourier matrix itself rather than the compressibility ( sparsity ) of the data.

Worldwide, the most common cause for goitre is iodine deficiency, usually seen in countries that do not use iodized salt.

Selenium deficiency is also considered a contributing factor.

Hemoglobin deficiency is, in general, strictly distinguished from hypoxemia, defined as decreased partial pressure of oxygen in blood, although both are causes of hypoxia ( insufficient oxygen supply to tissues ).

The major deficiency of Q1 is in the language: particularly noticeable in the opening lines of the famous " To be, or not to be " soliloquy: " To be, or not to be, aye there's the point.

Other classifications used also include: ḥasan ( good ), which refers to an otherwise ṣaḥīḥ report suffering from minor deficiency, or a weak report strengthened due to numerous other corroborating reports ; and munkar ( denounced ) which is a report that is rejected due to the presence of an unreliable transmitter contradicting another more reliable narrator.
