These electronegative elements are strongly associated with metal-bearing minerals, where they have formed water-insoluble compounds with the metals in the ores.

These metals can form useful silicides when deposited onto silicon.

These compounds can be reduced using either calcium or lithium metals in the following reactions:

These metals form an extremely thin layer of oxidized metal on the surface.

These metals are used in applications where corrosion resistance is important.

These other metals and their alloys can be cold-worked, or melted in simple pottery kilns and cast in molds ; but smelted iron requires hot-working and can be melted only in specially designed furnaces.

These are all modern, and there was no noticeable exploitation of metals or minerals prior to the modern era.

These range from biomaterials, to ceramics, to metals, to textile reinforced materials.

These metals are therefore relatively volatile, and are avoided in ultra-high vacuum systems.

These new military applications coincided with a population explosion throughout Europe in the 11th-14th centuries which increased the demand for precious metals in order to fill a currency shortage.

These tombs, which date to the Early Dynastic IIIa period ( approximately in the 25th or 24th century BC ), contained immense amounts of luxury items made out of precious metals, and semi-precious stones all of which would have had to been imported from long distances ( Iran, Afghanistan, India, Asia Minor, the Persian Gulf ).

These processes use a welding power supply to create and maintain an electric arc between an electrode and the base material to melt metals at the welding point.

These include fluctuating configurations of defects in metals, fluctuating occupancies of traps in semiconductors, and fluctuating domain structures in magnetic materials.

These orbitals are known as Landau levels, and at weak magnetic fields, their existence gives rise to many interesting " quantum oscillations " such as the Shubnikov – de Haas oscillations and the de Haas – van Alphen effect ( which is often used to map the Fermi surface of metals ).

These include iron, nickel, cobalt, some alloys of rare earth metals, and some naturally occurring minerals such as lodestone.

These include iron ore ( magnetite or lodestone ), cobalt and nickel, as well as the rare earth metals gadolinium and dysprosium ( when at a very low temperature ).

These organic acids are much less reactive with metals than are strong mineral acids like hydrochloric acid ( HCl ) or mixtures of HCl and hydrofluoric acid ( HF ).

These stars converted the pristine hydrogen, helium, and lithium formed by the Big Bang into heavier elements, such as carbon, oxygen, and metals.

These elements have also been referred to as earth metals and as triels.

These metals are all quite malleable, and humans ' initial development of hammering techniques was undoubtedly applied to these metals.

These include such metals as zinc, magnesium, and cadmium.

These narratives of coarse action and crude language appeared first in local newspapers, as a rule, and later found their way between book covers, though rarely into the planters' libraries beside the morocco-bound volumes of Horace, Mr. Addison, Mr. Pope, and Sir Walter Scott.

These are only halfway measures, and the answer will come when some way is found to allow the technical man in industry to progress without limit in salary and prestige ''.

These students, although they might read various articles in popular magazines, more often chose to report on articles found in the journals.

These are those operating and capital costs found to vary with number of customers regardless, or almost regardless, of power consumption.

These officers found no incriminating information.

These opportunities are to be found in certain cities in such crafts as auto mechanics, carpentry, drafting, electrical work, tool-and-die work, and sheet-metal work.

These materials are found mostly on the continental shelves and are thickest near large river mouths or off desert coasts.

These terms have historically been applied to any astronomical object orbiting the Sun that did not show the disk of a planet and was not observed to have the characteristics of an active comet, but as small objects in the outer Solar System were discovered, their volatile-based surfaces were found to more closely resemble comets, and so were often distinguished from traditional asteroids.

These fish are not found in caves north of the White River.

These ideas were found in a number of Kabbalistic works from the 13th century, and also among many mystics in the late 16th century.

These coatings are long gone and much of the architectural detail is sadly eroded, though detached fragments found in the ruins during consolidation give an impression of the original refined, rather austere, architectural effect.

These conclusions were, however, questioned by another review, which found that clozapine, amisulpride, and olanzapine and risperidone were more effective Clozapine has appeared to be more effective than other atypical antipsychotics, although it has previously been banned due to its potentially lethal side effects.

These creatures are found in the Mediterranean countries where many of these legends originated.

These are hominin autapomorphies, not found in other mammals or other bipeds.

These heterodox groups held widely divergent opinions but were united by a critical attitude towards the established religion whose explanations they found unsatisfactory and whose animal sacrifices increasingly distasteful and irrelevant.

These birds are absent from the southern tip of Florida and the highest elevations of the Appalachian Mountains, but are found in eastern Mexico and in Cuba.

These birds are generally solitary or found in pairs early in the year, but family groups are common in the late summer and winter roosts may have two dozen or more birds in a single covey.

These institutions are found in the United Kingdom ( UK ) and several other countries.

These species are found throughout tropical and subtropical South and Central America.

These can be tiny and circular, such as found on the Nurse Shark ( Ginglymostoma cirratum ), to extended and slit-like, such as found on the Wobbegongs ( Orectolobidae ).

These similarities include the energy carrier adenosine triphosphate ( ATP ), and the fact that all amino acids found in proteins are left-handed.

These bonds, which are stronger than the sp < sup > 3 </ sub > bonds found in alkanes and diamond, provide nanotubes with their unique strength.

These coins may be pocket change left from an international trip or an old coin found in circulation.
