Chemical Constitution of Enamel and Dentin
An understanding of the calcification process requires exact. knowledge of the nature and variations of composition of the mineral phase of calcified tissues. Other investigators have continued the study, begun years ago, of the composition of the inorganic salts of bone, but a comprehensive study of the results of analysis of enamel and. dentin by modern methods has not been described. Crowell...
متن کاملThe Relationship between Chemical Constitution and Taste.
Some time ago the author had occasion to prepare a quantity of phenyl thio carbamide, and while placing it in a bottle the dust flew around in the air. Another occupant of the laboratory, Dr. C. R. Noller, complained of the bitter taste of the dust, but the author, who was much closer, observed no taste and so stated. He even tasted some of the crystals and assured Dr. Noller they were tasteles...
متن کاملThe barbiturates: chemical constitution and nomenclature.
BARBITURIC acid was first synthesized by Conrad and Guthzeit in 1882, and in 1903 the 5:5-diethyl derivative was introduced into medicine as a hypnotic by Carl Fischer and von Mering, under the name of Veronal. In the past, barbituric acid was usually regarded as the cyclic ureide of malonic acid, i.e. as malonyl urea, and its structural formula written in a form which emphasized this relations...
متن کاملCombination of Colour Favoured and Colour
In this research we described the effective Hamiltonian theory and applied this theory to the calculation of current-current (Q1,2) and QCD penguin (Q3,…,6) c quark decay rates. We calculated the decay rates of semileptonic and hadronic of charm quark in the effective Hamiltonian theory. We investigated the decay rates of D meson decays according to Spectator Quark Model (SQM) for the calculati...
متن کاملEffects of stock density on texture-colour quality and chemical composition of rainbow trout (Oncorhynchus mykiss)
This study describes the effects of different stocking densities on texture/colour characteristics, protein content /amino acid and lipid content/fatty acid composition of rainbow trout fillet. Stocking density was selected 5 (Group A), 15 (Group B), 25 (Group C) kg fish m−3. Tukey’s Multiple Comparison Test showed insignificant differences between measured size/weight measurement and condition f...
