What's the difference between apyrous and combustible?
Apyrous
Definition:
(a.) Incombustible; capable of sustaining a strong heat without alteration of form or properties.
Example Sentences:
(1) The depression of ACh release induced by Mg-excess was completely antagonized by 4-APYR.
(2) The effect of 2-, and 4-aminopyridine (4-APYR) on the release mechanism of acetylcholine (ACh) from the nerve terminals of the Auerbach plexus-longitudinal muscle preparation of the guinea-pig ileum, suspended in eserinized Krebs' solution, was investigated.
(3) 4-APYR was able to increase ACh release in the absence of [Ca2+]o.
(4) Tetrodotoxin (TTX) prevented augmentation of ACh release by 4-APYR.
(5) 2- and 4-APYR increased the release of ACh from the nerve terminals at rest and at both low and high frequency stimulation.
(6) It is suggested that 4-APYR lowers the demand of nerve terminals for [Ca2+]o required for the excitation-secretion coupling process.
(7) The presence of a low concentration [Ca2+]o, however, is essential for the action of 4-APYR.
(8) However, when a Ca-chelating agent, EDTA, was also added to the Ca-free Krebs' solution, 4-APYR was entirely ineffective.
Combustible
Definition:
(a.) Capable of taking fire and burning; apt to catch fire; inflammable.
(a.) Easily kindled or excited; quick; fiery; irascible.
(n.) A substance that may be set on fire, or which is liable to take fire and burn.
Example Sentences:
(1) Solely infectious waste become removed hospital-intern and -extern on conditions of hygienic prevention, namely through secure packing during the transport, combustion or desinfection.
(2) Glucose, osmotic pressure, packed cell volume, PFC by combustion and volatilization were also measured in blood samples.
(3) N-heterocyclic aromatics are environmentally important carcinogenic pollutants produced by incomplete combustion of organic material.
(4) A removable, stainless-steel tube is present around the heated area, and this particular configuration makes it possible to begin every combustion procedure from room temperature, and consequently, to achieve a complete evacuation of air from the line even for heat-labile samples.
(5) Combustion-product toxicity of perfluorinated polymers in small-scale tests varied markedly under various exposure conditions.
(6) Although few relationships among combustion parameters and emissions were uncovered, patterns of emissions were evident, suggesting commonality and relationships among the waste stream constituents and emissions.
(7) Biological studies have demonstrated that concentrated extract of tars from combustion of shale oil are carcingenic to the skin of mice.
(8) Some compounds derived from tobacco combustion can be induce a response of secretory immune system, because antigen penetration is by respiratory tract epithelium, with IgA antibodies synthesis and immune complex (IC) generation.
(9) Waste products from coal combustion have the highest potential risk among the fossil fuel alternatives.
(10) Bicyclic phosphorus esters (BCP) originating from the combustion of fire-retardant polyurethane foam containing phosphorus are highly toxic compounds and potent antagonists of GABA-ergic receptors.
(11) Firefighters are routinely exposed to a wide variety of combustion products.
(12) Combustion gas drying had no effect for the larger PAHs such as benzo(a)pyrene but caused mean increases of between 41% and 126% for fluoranthene, pyrene and chrysene.
(13) A wet combustion method for the carbon determination was developed.
(14) The design-specified operating temperature was 800 degrees C in the primary combustion chamber and 1000 degrees C in the secondary chamber.
(15) Fullerenes C60 and C70, generated by combustion, have been shown previously to be produced in controlled laminar flames accompanied by other compounds having fullerene-like characteristics.
(16) There is growing concern over the detrimental health effects to firefighters produced by exposure to combustion byproducts of burning materials.
(17) Residential wood combustion accounted for 75% of the exposure to particle associated organics, but only 20% of the estimated cancer risk.
(18) Evidence for the atmospheric formation of nitro-PAH has come only recently, from observations that 2-nitropyrene (2-NP) and 2-nitrofluoranthene (2-NF) neither of which has been reported to be emitted from combustion sources, are among the major nitro-PAH present in ambient air.
(19) The combustion gases of cotton, polypropylene, acrylic, flame retardant (F.R.)
(20) Products of incomplete combustion are identified as a major source of carcinogenic risk in urban areas, especially those from small non-industrial sources.
