What's the difference between derivative and fluxion?
Derivative
Definition:
(a.) Obtained by derivation; derived; not radical, original, or fundamental; originating, deduced, or formed from something else; secondary; as, a derivative conveyance; a derivative word.
(n.) That which is derived; anything obtained or deduced from another.
(n.) A word formed from another word, by a prefix or suffix, an internal modification, or some other change; a word which takes its origin from a root.
(n.) A chord, not fundamental, but obtained from another by inversion; or, vice versa, a ground tone or root implied in its harmonics in an actual chord.
(n.) An agent which is adapted to produce a derivation (in the medical sense).
(n.) A derived function; a function obtained from a given function by a certain algebraic process.
(n.) A substance so related to another substance by modification or partial substitution as to be regarded as derived from it; thus, the amido compounds are derivatives of ammonia, and the hydrocarbons are derivatives of methane, benzene, etc.
Example Sentences:

(7) Release of 51Cr was apparently a function of immune thymus-derived lymphocytes (T cells) because it was abrogated by prior incubation of spleen cells with anti-thymus antiserum and complement but was undiminished by passage of spleen cells through nylon-wool columns.
(8) PMNs could be primed for PMA-triggered oxidative burst by muramyl peptide molecules (MDP) and two of its adjuvant active nonpyrogenic derivatives.
(9) Recent studies have shown that an aberration in platelet-derived growth factor gene expression is unlikely to be a factor in proliferation of smooth-muscle cells.
(10) The macrophage-derived product, interleukin 1 (IL 1) is thought to play an important regulatory role in the proliferation of T lymphocytes; however, its mechanism of action is unknown.
(11) In the upper limb and facial forms of familial amyloidotic polyneuropathy first recorded in Swiss and Finns respectively, the differences in their patterns of neurological disease and ocular lesions could be the result of their amyloids deriving from proteins other than prealbumin.
(12) The antiproliferative activity of IFN was studied using the parental L cell line, a tk- derivative, and a tk- (tk+) subline into which the tk gene of herpes simplex virus was introduced.
(13) Bipolar derivations with the maximum PSE always included the locations with the maximum PSE obtained from a linked ears reference.
(14) Only those derivatives with a free amino group and net positive charge in the side chain were effective.
(15) Northern blot analysis with an 18-mer radiolabelled oligonucleotide, derived from an ALP specific cDNA clone, revealed a specific mRNA of about 700-800 nucleotides in HS-24 tumor cells.
(16) The mortality data were derived from the reports by Miyagi Prefectural Government.
(17) Ferrocene derivatives, in general, show a degree of versatility, coupling the electron-transfer reactions of many enzymes.
(18) The ADAM derivative of carnitine was separated from decomposition products of the reagent and related compounds such as amino acid derivatives on a silica gel column eluted with methanol-5% aqueous SDS-phosphoric acid (990:10:1).
(19) This doxorubicin derivative did not bind to Sepharose which was conjugated with cardiac actin.
(20) In the triploids, the 40 female chromosomes present (mouse, n = 20) were derived from a single diploid pronucleus formed after the extrusion of a first polar body, and following the monospermic fertilization of primary oocytes.
Fluxion
Definition:
(n.) The act of flowing.
(n.) The matter that flows.
(n.) Fusion; the running of metals into a fluid state.
(n.) An unnatural or excessive flow of blood or fluid toward any organ; a determination.
(n.) A constantly varying indication.
(n.) The infinitely small increase or decrease of a variable or flowing quantity in a certain infinitely small and constant period of time; the rate of variation of a fluent; an incerement; a differential.
(n.) A method of analysis developed by Newton, and based on the conception of all magnitudes as generated by motion, and involving in their changes the notion of velocity or rate of change. Its results are the same as those of the differential and integral calculus, from which it differs little except in notation and logical method.
Example Sentences:
(1) Comprehending the nature of this property which couples ionic fluxions into mentality is the quintessential problem of science.
(2) We also note that during the timescale of our simulation (126 ps) the hydrogen bonds between the hydroxide hydrogen atom and Thr199 and the one between Thr199 and Glu106 are not fluxional.
(3) The first equivalent of cobalt(II) ions per dimer binds in an essentially unspecific and possibly fluxional fashion, giving rise to a six-coordinated chromophore.
(4) A more exact time sequence cannot be established due to fluxional transitions and, particularly, to marked individual veriations.
(5) Electronic and 1H NMR titration with Co2+ ions show that the initial amount of fluxional cobalt is smaller than in the absence of magnesium and that A-B pairs are more readily formed.
(6) This asymmetry is not detected in solution by proton NMR spectroscopy at room temperature; however, at -90 degrees C spectroscopic changes suggest slowing of a fluxional process.
(7) We suggest that the Gd(DTPA)-conjugate systems have a fluxional coordination sphere whereby the amount of inner-sphere coordinated water varies from near zero at 5 degrees C to a high of two near 37 degrees C.
