What's the difference between anthracite and carbonized?
(n.) A hard, compact variety of mineral coal, of high luster, differing from bituminous coal in containing little or no bitumen, in consequence of which it burns with a nearly non luminous flame. The purer specimens consist almost wholly of carbon. Also called glance coal and blind coal.
(1) But then a mismanaged clean-up in an underground garbage dump ignited a seam of anthracite eight miles long that proved impossible to extinguish.
(2) Eventually, long before all that anthracite has burned away, the town will probably collapse into the empty seam below and disappear completely.
(3) Significantly greater (P less than 0.05) depression (coinhibition) of viral interferon induction (greater than 83%) resulted when bioactivated B[a]P was incorporated with coal particles representative of coal rank (anthracite, bituminous, lignite, peat).
(4) Two kinds of coal mine dust, low rank with high quartz (bituminous) and high rank with low quartz (anthracite), were assayed for ability to induce alveolitis and to stimulate interleukin-1 release from normal alveolar macrophages in vitro.
(5) The union used the hearings of the US Anthracite Coal Strike Commission of 1902-3 to draw public attention to "miners' asthma."
(6) Soon roads started to melt, and a huge fiery chasm opened up in the back garden of a house, as the ground collapsed into the vast anthracite seam below.
(7) Examination of one such soil shows that the organic material is finely divided anthracite coal.
(8) In these 250 mines a progressive and five-fold increase in prevalence was observed from collieries mining low-rank (bituminous) coal to those mining coal of high ranks (anthracite and high-grade steam and coking coal).
(9) Studies with the organic solvent extracts of all five ranks of coal indicate that the extracts of bituminous, lignite, and peat, but not anthracite, induced SCEs.
(10) The apparent excess prevalence of radiographic small rounded opacities in anthracite surface coal mine drillers suggests that quartz exposures have been increased.
(11) Freshly ground anthracite coal produced greater concentration of free radicals than the bituminous coal, and the radical reactivity was also greater for the anthracite.
(12) In 1984-1985, medical examinations consisting of a chest radiograph, spirometry test, and questionnaire on work history, respiratory symptoms, and smoking history were administered to 1,061 white males who were employed at 31 coal cleaning plants and strip coal mines in the anthracite coal region of northeastern Pennsylvania.
(13) Total mutagenic activity (the activity per gram of coal pyrolyzed), however, varied with coal type according to the order: high volatile bituminous much greater than subbituminous = lignite much greater than anthracite, due primarily to high organic yield during high volatile bituminous coal pyrolysis.
(14) Similar experiments conducted with water extracts show that bituminous, lignite, and peat, but not sub-bituminous extracts, induced SCEs, and that anthracite was equivocal.
(15) The specific mutagenic activity (i.e., the activity per unit sample weight) of extracts from particulates and volatiles captured on XAD-2 resin varied with coal type according to the order: subbituminous greater than high volatile bituminous greater than lignite greater than anthracite.
(16) Given that there is enough anthracite coal down there to burn for another 250 years, most people have long since abandoned Centralia (although remarkably, Bill Bryson found 10 people still in residence when he visited to research his book A Walk In The Woods in 1996).
(17) It develops especially in miners working in anthracite coal-mines and in persons exposed to silica and asbestos.
(18) The effect we observed regarding the anthracite lustre using low temperatures was typical, and the best results were obtained in dental roots with eight color scales.
(19) The reactivity of the newly produced free radicals in the anthracite dust correlated with the dust's toxicity.
(20) An experiment on rats in vivo with bituminous, anthracitic and brown coal dusts from eight coal mines showed that the fibrogenic degree in experimental rats was related to the free silica contents of the coal dust, which varied from 0.72% to 9.84% in our experiment.
Carbonized

(1) Carbon dioxide (CO2) levels, volumes, and temperatures of expired gas were measured from the tracheal and esophageal tubes.
(2) Biochemical, immunocytochemical and histochemical methods were used to study the effect of chronic acetazolamide treatment on carbonic anhydrase (CA) isoenzymes in the rat kidney.
(3) To quantify the size of the lesion in mice, the area of the infarct on the brain surface was assessed planimetrically 48 h after MCA occlusion by transcardial perfusion of carbon black.
(4) Ethanol and L-ethionine induce acute steatosis without necrosis, whereas azaserine, carbon tetrachloride, and D-galactosamine are known to produce steatosis with varying degrees of hepatic necrosis.
(5) Heart rate (HR), pulmonary ventilation (V), oxygen consumption (VO2), carbon dioxide production (VCO2), and respiratory quotient (RQ) were measured.
(6) Given Australia's number one position as the worst carbon emitter per capita among major western nations it seems hardly surprising that islanders from Fiji, Samoa, Vanuatu and other small island developing states have been turning to Australia with growing exasperation demanding the country demonstrate an appropriate response and responsibility.
(7) 4) Parents imagined that fruit drinks, carbonated beverages and beverages with lactic acid promoted tooth decay.
(8) This capacity is expressed during incubation of the bacteria with the substrate and needs a source of carbon and other energy metabolites.
(9) The disappearance of the herbicide, Avadex (40% diallate), from five agricultural soils (differing in either pH, carbon content, or nitrogen content), incubated under sterile and non-sterile conditions, was followed for a period of 20 weeks.
(10) Environment groups Environment groups that have strongly backed low-carbon power have barely wavered in their opposition to nuclear in the last decade, although their arguments now are now much about the cost than the danger it might pose.
(11) Cultured cells from fourth to ninth passage showed positive labelling for S 100 protein, carbonic anydrase (CAA), glutamine synthetase (GS), alpha cristallin (alpha C) and polyclonal glial fibrillary acidic protein (GFAP) antibody, but were negative for both monoclonal GFAP antibody and also for Muller cells in the retina.
(12) They argue that the US, the world's largest producer of greenhouse gases per capita (China recently surpassed us in sheer volume), needs to lead the fight to limit carbon emissions, rather continuing to block global treaties as it has done in the past.
(13) Thin layers of carbon (20 microns) and vacuoles (30 microns) suggested a large temperature gradient along the tissue ablation front.
(14) Aryl hydrocarbon hydroxylase (AHH) inducibility, carbon monoxide in expired air (CO), serum gammaglutamyl-transferase (GGT), and total cholesterol were compared in equal-sized, age-matched samples of healthy middle-aged males born in 1921, 1934-1936, and 1946 attending the ongoing preventive medical population program in Malmö.
(15) The disappearance of ribosomes in Escherichia coli cells starved for a carbon source was studied.
(16) It was shown that the levels of ATP and ADP in the mycelium depended on the carbon source: the maximum and minimum ATP concentrations were found on the glucose and acetate media respectively, the maximum and minimum ADP concentrations showed inverse dependence.
(17) The mechanism by which such high levels were attained was primrily a combination of arterial hypoxia and a high carbon monoxide yield from tobacco.
(18) Nick Robins, head of the Climate Change Centre at HSBC, said: "If you think about low-carbon energy only in terms of carbon, then things look tough [in terms of not using coal].
(19) Immediately prior to and at maximal workloads, carbon monoxide shifted into extravascular spaces and returned to the vascular space within five minutes after exercise stopped.
(20) The purity and configuration of each isomer of the free acid and N-chloroacetylated derivative were ascertained by: (a) paper chromatography in five solvent systems, (b) elemental analysis, (c) Van Slyke nitrous acid determination of alpha-carbonyl carbon, and (d) Van Slyke ninhydrin determination of alpha-carbonyl carbon, and (e) optical rotation.
