Latin terms

Others report that the term first principles is being increasingly used because the Latin term ab initio can been seen as unnecessarily elitist and that there is no scientific significance in using one term rather than the other one. Others disagree, suggesting that first principles is favored by the DFT community since in this kind of work it is quite clear that some semi-empirical elements are introduced whereas the wavefunction or traditional ab initio approaches are less semi-empirical. [Pg.95]

The Latin term terra alba (white earth) is often used indiscriminately to refer to such white minerals as chalk, gypsum, and kaolin. Chalk, also known as... [Pg.92]

The Latin term "ab initio" means "from the beginning" or "from first principles." Ab initio calculations involve no experimental (empirical) data they are derived solely from theory. (Note that ab initio should not be italicized or used with quotation marks.)... [Pg.96]

Exactly what is a paranormal experience or phenomenon Para is derived from a Latin term for beyond. So paranormal means beyond normal, or things that do not fit what we experience through our five senses alone and which do not follow the laws we observe in nature and in science. Paranormal experiences and phenomena run the gamut from the awesome and marvelous, such as angels and miracles, to the downright terrifying, such as vampires and werewolves. [Pg.7]

This precipitate was boiled with aqua regia, and a volatile Os compound came off The remaining solution was treated with NH4CI which precipitated a salt of a new element, which had previously been called ruthenium, ruthenia being a latinized term for Russia. [Pg.313]

One of the first people to apply science to medicine was the ancient Greek physician Hippocrates (ca. 460-377 b.c.e.). Influenced by the idea that the world is composed of four substances—earth, air, fire, and water—as taught by the Greek philosopher Empedocles (ca. 495-435 b.c.e.), Hippocrates proposed that four fluids are critical in determining a person s state of health. These fluids, known as humors (from a Latin term for moisture), were called blood, yellow bile, black bile, and phlegm. According to Hippocrates, an imbalance in these humors caused disease. Later, people associated a specific temperament or personality with these humors, a theory that was one of the earliest attempts to explain moods and emotions. Blood, for example, was associated with an optimistic disposition, while black bile corresponded to depression. [Pg.70]

Should development come after speciation Yes, of course, in the new model it is natural, one produces the Anlage and develops it to its potential. The word evolution is derived from the latin term evolvere which means to roll out and that describes precisely the process postulated in the Genomic Potential Hypothesis for the post-Cambrian time. With speciation behind us there remain two distinct ph ases of evolution in the widest sense of the word, the streamlining of the chemistry in the nucleus, which leaves no traces other than species-specific stem cells, and the post-Cambrian unrolling of species and variants that produces a spectacular display of phenotypes. Looks like we are on the right track. [Pg.51]

Obviously, chemical induction is of great interest, because, on one hand, it allows the induction and acceleration of non-spontaneous reaction and, intrinsically, remains the unique method by which to affect such reactions (except for reactions proceeding under the influence of photochemical and ionizing radiation). On the other hand, chemical induction plays a significant role in biochemical processes. The literal translation from Latin term interference is mutual (inter) collision (ferio), which shows the total situation. [Pg.23]

Q You may also have noticed the term ferrate to describe iron. This is a by-product of the old naming system that used the Latin terms for elements instead of Roman numerals to indicate their names (and charges). In this naming system, these older Latin names of elements are given an -ate ending. Most of these older forms have been discarded, except they do appear here. The Latin names for elements are responsible for the symbols that may have been difficult for you to memorize because they don t start with the same letters as the elements, common names. Some examples of these older names and their use in naming anions in complexes are seen below ... [Pg.365]

The term corrosion has its origin in Latin. The Latin term rodere means gnawing and corrodere means gnawing to pieces . It is rather interesting to examine the historical aspects of the developments of corrosion. Metallic corrosion has no doubt been a problem since common metals were first put to use. Most metals occur in nature as compounds, such as oxides, sulfides, silicates or carbonates (very few metals occur in native form). The obvious reason is the thermodynamic stability of the compounds as opposed to the metals. The process of extraction of a metal from the ore is reduction. [Pg.3]

Do not use italic type for common Latin terms and abbreviations. [Pg.154]

The same principle holds no matter what information is being repeated provide each reference in its entirety. Do not use the Latin terms ibid, (in the same place)... [Pg.298]

MAGALE — A Latin term by which Paracelsus understands every species of Perfume made from minerals. [Pg.333]

Carbon was officially classified as an element near the end of the 18th century. In 1787, four French chemists-Guyton de Morveau, Antoine Laurent Lavoisier, Claude Louis Berhollet, and Antoine Francois Fourcroy—wrote a book outlining a method for naming chemical substances, A Method for Chemical Nomenclature. The name they gave to carbon was carbone, which was based on the earlier Latin term for charcoal, charbon. [Pg.103]

Mercury is a transition metal. A transition metal is one of the elements found between Groups 2 (IIA) and 13 (IIIA) in the periodic table. The periodic table is a chart that shows how chemical elements are related to one another. Mercury has long been known as quicksilver, because it is a silver liquid. The chemical symbol also reflects this property. The symbol, Hg, comes from the Latin term hydrarQirum, meaning watery silver. ... [Pg.341]
