Whether this abnormal TSH differs chemically from pituitary TSH, or is, alternatively, normal TSH with its period of effectiveness modified by some other blood constituent, cannot be decided without chemical study of the activity in the blood of these patients and a comparison of the substance responsible for the blood activity with pituitary Aj.

Spoilage by chemical action results from the reaction of one group of components in the food with others or with its environment, as in corrosion of the walls of metal containers or the reaction of fats with oxygen in the air to produce rancidity.

Like other groups, the members of this family show patterns in its electronic configuration, especially the outermost shells, resulting in trends in chemical behavior:

The number of electrons in each element's electron shells, particularly the outermost valence shell, is the primary factor in determining its chemical bonding behavior.

Argon ( αργος, Greek meaning " inactive ", in reference to its chemical inactivity ) was suspected to be present in air by Henry Cavendish in 1785 but was not isolated until 1894 by Lord Rayleigh and Sir William Ramsay in Scotland in an experiment in which they removed all of the oxygen, carbon dioxide, water and nitrogen from a sample of clean air.

As with most lanthanides and actinides, actinium assumes oxidation state + 3 in nearly all its chemical compounds.

An atom is classified according to the number of protons and neutrons in its nucleus: the number of protons determines the chemical element, and the number of neutrons determines the isotope of the element.

A matrix can have a considerable effect on the way a chemical analysis is conducted and the quality of its results.

* Of or relating to the Atom, the smallest particle of a chemical element that retains its chemical properties

Its chemical composition makes it difficult to match the amber to its producers – it is most similar to the resins produced by flowering plants ; however, there are no flowering plant fossils until the Cretaceous, and they were not common until the Upper Cretaceous.

* 1997 – The Chemical Weapons Convention of 1993 enters into force, outlawing the production, stockpiling and use of chemical weapons by its signatories.

Some early scientists such as Georg Ernst Stahl ( 1659-1734 ) and Francisque Bouillier ( 1813 – 1899 ) had supported a form of animism which life and mind, the directive principle in evolution and growth, holding that all cannot be traced back to chemical and mechanical processes, but that there is a directive force which guides energy without altering its amount.

Antibacterials such as metronidazole, tinidazole, cephamandole, latamoxef, cefoperazone, cefmenoxime, and furazolidone, cause a disulfiram-like chemical reaction with alcohol by inhibiting its breakdown by acetaldehyde dehydrogenase, which may result in vomiting, nausea, and shortness of breath.

He showed that, although matter can change its state in a chemical reaction, the total mass of matter is the same at the end as at the beginning of every chemical change.

Adhesion, the attachment between adhesive and substrate may occur either by mechanical means, in which the adhesive works its way into small pores of the substrate, or by one of several chemical mechanisms.

Plant potash lent the name to the element potassium, which was first derived from caustic potash, and also gave potassium its chemical symbol K ( cf German Kalium ), which ultimately derives from alkali.

In systems engineering it may involve black-box testing performed on a system ( for example: a piece of software, lots of manufactured mechanical parts, or batches of chemical products ) prior to its delivery.

Because of its high chemical reactivity barium is never found in nature as a free element.

This gradual transformation is an important consideration when studying the properties of elemental berkelium and its chemical compounds, since the formation of californium brings not only chemical contamination, but also self-radiation damage, and self-heating from the emitted alpha particles.

Thus the discovery report by the Berkeley group reads: " It is suggested that element 97 be given the name berkelium ( symbol Bk ) after the city of Berkeley in a manner similar to that used in naming its chemical homologue terbium ( atomic number 65 ) whose name was derived from the town of Ytterby, Sweden, where the rare earth minerals were first found.

The proprietor is able to create a leadership impossible in the corporate structure with its board of directors and stockholders.

Although the wood has been changed to coal, much of it still retains its original cell structure.

Af appeared to be well suited for the study of these matters, since it is a normal paramagnet, with three unpaired electrons on the chromium, its crystal structure is very simple, and the unknown position of the hydrogen in the strong Af bond provides structural interest.

The nest itself, the structure that in some cases housed about 2,000 individuals when the season was at its peak, is now rapidly destroyed by the scavenging larvae of certain beetles and moths.

Each year from 1941 on, its medical staff had conducted intensive field investigations to determine changes in population structure and vital rates and, as its primary objective, the incidence of major diseases.

Years of patient application of compost and leaf mulching has changed the structure of the soil and its water-holding capacity.

Readers unacquainted with its reputation as a satirical work often do not immediately realize that Swift was not seriously proposing cannibalism and infanticide, nor would readers unfamiliar with the satires of Horace and Juvenal recognize that Swift's essay follows the rules and structure of Latin satires.

Originally, the Church of England was self-contained and relied for its unity and identity on its own history, its traditional legal and episcopal structure and its status as an established church of the state.

All 38 provinces of the Anglican Communion are autonomous, each with its own primate and governing structure.

Foucault's author function is the idea that an author exists only as a function of a written work, a part of its structure, but not necessarily part of the interpretive process.

** Photolithography: the aspect ratio of an etched, or deposited structure is the ratio of the height of its vertical side wall to its width.

In October 2009, when visiting Yerevan, the World Bank ’ s managing director, Ngozi Okonjo-Iweala, warned that Armenia will not reach a higher level of development unless its leadership changes the " oligopolistic " structure of the national economy, bolsters the rule of law and shows " zero tolerance " towards corruption.

It is, in some sense, a symmetry of the object, and a way of mapping the object to itself while preserving all of its structure.

* Does cognition have its own structure?

This causes the iron crystals to deform intrinsically when the crystal structure tries to change to its low temperature state, inducing great hardness.

The generic structure of an alpha amino acid in its unionized form

Architecturally it is considered an innovative work for its steel structure and curtain walls – the façade is self-supporting.

Every lattice element of the structure is in its proper place, whether it is a single atom or a molecular grouping.

Ptolemy's view of Germans in the region indicates that the tribal structure had lost its grip in the Black Forest region and was replaced by a canton structure.
