Furthermore, saliva serves a lubricative function, wetting food and permitting the initiation of swallowing, and protecting the mucosal surfaces of the oral cavity from desiccation.

This lubricative function of saliva allows the food bolus to be passed easily from the mouth into the esophagus.

The lubricative fluid contains water, pyridine, squalene, urea, acetic acid, lactic acid, complex alcohols and glycols, ketones, and aldehydes.

This warrant can arise from properties of the belief ( such as its being self-evident or self-justifying ).

For example, every continuous probability distribution has a median, which may be estimated using the sample median or the Hodges-Lehmann-Sen estimator, which has good properties when the data arise from simple random sampling.

The electric charge, colour, and parity properties of such fermions would arise in the same way as for the first generation.

The question, then, is how it can be possible for conscious experiences to arise out of a lump of gray matter endowed with nothing but electrochemical properties.

Because A-and B-terms arise from the properties of states, all singlet and triplet excited states are given in figure 2.

Numerical analysis takes advantage of many of the properties of orthogonal matrices for numerical linear algebra, and they arise naturally.

He correctly appreciated that the insulating properties of these natural materials arise from the fact that they inhibit the convection of air.

Ramanujan ( 1887 – 1920 ) used properties of the Gamma function to give a simpler proof, from which the concept of Ramanujan primes would later arise, and Erdős ( 1913 – 1996 ) in 1932 published a simpler proof using the Chebyshev function ϑ, defined as:

Their well-known properties can be derived from their definitions, as linear maps or more generally ; and the rules for manipulations of tensors arise as an extension of linear algebra to multilinear algebra.

Some monetary reformers believe that in a genuine free market, where government did not impose a monopoly currency on the populace, a gold standard or silver standard monetary system would arise spontaneously out of the free market because of their unique properties: their extraordinary malleability, their strong resistance to forgery, their character as stable and impervious to decay, and their inherently limited supply.

Group extensions arise in the context of the extension problem, where the groups Q and N are known and the properties of G are to be determined.

By letting the network learn on its own, structure and computational properties naturally arise.

Multiple receptor isoforms with distinct brain distributions and functional properties arise by selective splicing of the NR1 transcripts and differential expression of the NR2 subunits.

Chomsky has argued that many of the properties of a generative grammar arise from an " innate " universal grammar.

Although a general tridiagonal matrix is not necessarily symmetric or Hermitian, many of those that arise when solving linear algebra problems have one of these properties.

This method is useful for preventing artifacts that arise from vacuum simulations and reproduces bulk solvent properties well, but cannot reproduce situations in which individual water molecules have interesting interactions with the molecules under study.

The point group of a crystal, among other things, determines directional variation of the physical properties that arise from its structure, including optical properties such as whether it is birefringent, or whether it shows the Pockels effect.

* Magnetic monopoles arise in condensed matter systems such as spin ice and carry an effective magnetic charge as well as being endowed with other typical quasiparticle properties such as an effective mass.

Bands have different widths, based upon the properties of the atomic orbitals from which they arise.

Further misunderstandings arise because of the associative character of certain ACT-R properties, such as chunks spreading activation to each other, or chunks and productions carrying quantitative properties relevant to their selection.

The spacetime manifold and properties of locality and nonlocality then arise from an order in such pre-space.

The magnetic properties arise from the fully pi-conjugated nitrogen-containing backbone combined with molecular charge transfer side groups.

At the present time we do not know by what biochemical mechanism TSH acts on the thyroid, but for bio-assay of the hormone there are a number of properties by which its activity may be estimated, including release of iodine from the thyroid, increase in thyroid weight, increase in mean height of the follicular cells and increase in the thyroidal uptake of Af.

The importance of this 5 can largely be explained by the natural mathematical properties of the middle number and its special relationship to all the rest of the numbers -- quite apart from any numerological considerations, which is to say, any symbolic meaning arbitrarily assigned to it.

The sun, blazing hot as prophesied, was far from kind to Mrs. Kirby's varicolored properties.

The close similarity of physical and chemical properties of actinium and lanthanum makes separation of actinium from the ore impractical.

Actinium has similar chemical properties as lanthanum and other lanthanides, and therefore these elements are difficult to separate when extracting from uranium ores.

Alloys usually have different properties from those of the component elements.

The physical properties, such as density, reactivity, Young's modulus, and electrical and thermal conductivity, of an alloy may not differ greatly from those of its elements, but engineering properties such as tensile strength and shear strength may be substantially different from those of the constituent materials.

Area can be defined as a function from a collection M of special kind of plane figures ( termed measurable sets ) to the set of real numbers which satisfies the following properties:

The S-box used is derived from the multiplicative inverse over GF ( 2 < sup > 8 </ sup >), known to have good non-linearity properties.

In fluorescence spectroscopy, the fluorescence anisotropy, calculated from the polarization properties of fluorescence from samples excited with plane-polarized light, is used, e. g., to determine the shape of a macromolecule.

Known to the Iranians by the Pahlavi compound word kah-ruba ( from kah “ straw ” plus rubay “ attract, snatch ,” referring to its electrical properties ), which entered Arabic as kahraba ' or kahraba, it too was called amber in Europe ( Old French and Middle English ambre ).

After James Prescott Joule had determined the mechanical equivalent of heat, Lord Kelvin approached the question from an entirely different point of view, and in 1848 devised a scale of absolute temperature which was independent of the properties of any particular substance and was based solely on the fundamental laws of thermodynamics.

Even after leaving the abbacy of Tavistock, he continued to hold two properties from the abbey until his death.

Tetrahydrocannabinol ( THC ) and some other cannabinoids, either from the Cannabis sativa plant or synthetic, have analgesic properties, although the use of cannabis derivatives is currently illegal in many countries.

They and their clerics and their properties were exempt from all jurisdiction except the immediate jurisdiction of the Pope, and they were not subject to the judgments of the Auditor of Causes, or to the Cardinal Vicar.

To derive the equations of aerodynamics, fluid properties such as density and velocity are assumed to be well-defined at infinitely small points, and to vary continuously from one point to another.

Its properties come solely from the power of unlimited recursion.

A standard solution to this problem is found in Zermelo's set theory, which does not allow the unrestricted formation of sets from arbitrary properties.

The properties of the resulting substance resembled that of an intermediate of chlorine and iodine ; with those results he tried to prove that the substance was iodine monochloride ( ICl ), but after failing to do so he was sure that he had found a new element and named it muride, derived from the Latin word muria for brine.

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.

The conceptual difficulty of bare particulars was illustrated by John Locke when he described a substance by itself, apart from its properties, as " something, I know not what.
