What's the difference between brewsterite and hydrothermal?
Brewsterite
Definition:
(n.) A rare zeolitic mineral occurring in white monoclinic crystals with pearly luster. It is a hydrous silicate of aluminia, baryta, and strontia.
Example Sentences:
Hydrothermal
Definition:
(a.) Of or pertaining to hot water; -- used esp. with reference to the action of heated waters in dissolving, redepositing, and otherwise producing mineral changes within the crust of the globe.
Example Sentences:
(1) Liquid-dominated hydrothermal reservoirs, which contain saline fluids at high temperatures and pressures, have a significant potential for contamination of the environment by heavy metals.
(2) Hydroxyapatite ceramics with zirconia dispersion from fine powders synthesized hydrothermally were post-sintered at 1000-1300 degrees C under 200 MPa of argon for 1 h without capsules, after normal sintering in air at 1200 degrees C for 3 h. Densification was most significant with post-sintering at 1200 degrees C. Fracture toughness, Vickers hardness and elastic properties of these materials were investigated.
(3) The effect of different modes of the hydrothermal treatment of buckwheat and of the grit cooking on a change in the composition of sterols and phospholipids was investigated.
(4) Whether you're a microbe at a hydrothermal vent, or a computer programmer at a software company, we all function on that same biochemistry."
(5) Collagen reticulation was studied as a function of fiber location along these tendons by measuring hydrothermal isometric tension (HIT).
(6) Replicas of porous hydroxyapatite that had been obtained after hydrothermal conversion of the calcium carbonate exoskeleton of coral (genus Goniopora) were implanted intramuscularly in twenty-four adult male baboons (Papio ursinus).
(7) The results suggest that the 1% SDS solution destroys the fresh material causing acellularity, extreme fragmentation and swelling of the collagen, together with a significant loss of hydrothermal stability.
(8) In studying the effect of ionizing radiation on the properties of human Achilles tendon collagen fibres, the following parameters were analyzed: hydrothermal contraction temperature, module of elasticity, the number of cross-links, free and bound water levels, acids-soluble fraction content, and ultrastructure.
(9) These favourable results are promoting the active intervention by endoscopic treatment with a electro-hydrothermic probe.
(10) Radiographic and densitometric evaluation of a new type of bone graft substitute derived from reef-building sea coral via a hydrothermal chemical exchange process was undertaken in a canine diaphyseal defect model.
(11) We interpret these organs as being eyes adapted for detection of low-level illumination and suggest that they evolved in response to a source of radiation associated with the environment of hydrothermal vents.
(12) For example, the rate of production of several proteins by some hydrothermal vent archaebacteria and the degree of saturation of membrane lipids in other deep-sea bacteria have been found to change as a result of cultivation at high pressure.
(13) General limits of viability are: (a) the susceptibility of the covalent structure of the polypeptide chain toward hydrolysis or hydrothermal degradation; (b) the competition of extreme solvent parameters with the weak electrostatic and hydrophobic interactions involved in protein stabilization; (c) perturbations of the folding and assembly of proteins; and (d) 'dislocation' of biochemical pathways due to effects of extreme conditions on the intricate network of metabolic reactions.
(14) During culinary treatment these changes are levelled out, but in the end the level of virtually all types of sugar is higher in the gruel cooked with hydrothermally treated grit than in that prepared with initial, untreated grit.
(15) Hydrothermal processing results in significant changes occurring individual sugars of the grit.
(16) papatasi number at the very beginning of the irrigation period; 2) formation of stably high or low Phlebotomus numbers due to stabilization of hydrothermal regime in the holes of great gerbils.
(17) Lastly, comparisons of species from the cold deep sea with those from hydrothermal vents have shown that adaptations to both temperature and pressure play critical roles in determining the distribution patterns of deep-living species.
(18) The selective extraction of proteoglycans resulted in a great accumulation of calcium salts in the tissue, which, moreover, had a reduced hydrothermal stability.
(19) While not changing the qualitative composition of sterols and phospholipids, the hydrothermal and culinary treatment was found to produce some changes in the correlation of their individual fractions.
(20) Hydrothermic treatments usually have no effect on starch digestibility but can be used for B-type starches.
