Thyroid Function TestDrug interaction A 64-year-old woman receiving levothyroxine sodium experienced hypothyroidism during concomitant treatment with calcium carbonate. The woman, whose hypothyroidism had been well controlled with levothyroxine sodium 88 g/day for many years, was diagnosed with bone ...
This result effectively resolves the paradox of a drowned carbonate platform. Test modelling runs conducted with 2·5 m and 15 m initial sea water depths at bracketed rates of relative sea-level rise have determined how fast the system catches up and maintains the 'keep-up' phase. This is ...
Carbon isotopic composition of Neoproterozoic glacial carbonates as a test of paleoceanographic models for snowball Earth phenomena excursions widely observed in those carbonate rocks require an explanation that involves a short-term perturbation of the global carbon cycle during ...

Carbon dioxide gas is emitted during the reaction between the acid and carbonate fraction of the test specimen. A pressure gauge, attached to the reactor, is pre-calibrated with reagent grade calcium carbonate to provide a direct measurement of the carbonate content. This test is performed in an...
Methods; PCCC was immersed into physiological saline and culture fluid to acquire PCCC solution, the experiments include acute toxicity testing, minute nucleus test and muscle implant test. Results: PCCC had no gene mutation, and no significant immune reaction of foreign body was observed by ...
Walker Lake, an alkaline closed-basin lake in western Nevada, has experienced a well-documented lake-level decline since 1880 and provides a test case for CAS as a lake-level proxy. By extracting the CAS from sedimentary carbonate and tufas that have been age dated, we can relate these ...
“Chelatable lead” denotes the amount available for binding to a chelating agent in a mobilization test. BB, total body burden; t, biological half-time; y, year; mo, month; min, minute. 2.5.1 Absorption 2.5.1.1 Inhalation Lead may be inhaled as an aerosol. The pattern of deposition ...
A 3D model of the clinostratified body at Dibona was then realized on the basis of LiDAR and petrographic analysis to test if it fits in the larger scale conceptual model. The original inclination of clinoforms ( ~ 25°) and their amplitude ( ~ 30 m) point to a deltaic environment, ...
This paper presents the experimental results of the catalytic effect of fourteen different alkali metal compounds on the Carbon-carbon dioxide reaction in a benchscale unit under atmospheric pressure. The carbonaceous samples are impregnated with these compounds in the test. It has been shown that cok...
This technique is used to measure thegastric acidsecretory response induced by a meal. The gastric pH is raised to 5.5 by the infusion ofsodium hydrogencarbonateor hydroxide. A homogenizedtest meal, also with a pH adjusted to 5.5, is ingested or instilled through a nasogastric tube. For a ...
