Objectives. Triple barium–strontium–calcium carbonates of various grades are widely used for depositing oxide coatings on cathodes electrovacuum devices. Of all types in devices, among the most common, due to combining efficiency, durability, operation at relatively low temperatures, and a cost. The aims this work were to: create technology synthesis triple with nonequilibrium phase composition...

The barium is often used in radiocontrast examinations of the digestive system because of mucosal absorption is limited. Massive barium aspiration is a rare complication, especially when there is no anatomic or neurological defi cit. The depending on barium concentration can cause various lung effects. When the literature is reviewed, barium aspiration may be asymptomatic or lethal in massive a...

In this research we report synthesis of new Barium- Cobalt precursor complex with 2,6- pyridine dicarboxylic acid (dipic).Thecomplex[Ba(H2O)6][Co(dipic)2[(1)has been characterized using spectral methods (FT-IR, UV–Vis),elemental analysis and Cyclic voltammetric (CV) method. Also in this study we report thermal decomposition of inorganic precursor complex of (1).Characterization of the binary ox...

The oxidation reactions of BaLaCuS3 in the artificial air atmosphere were studied at different heating rates temperature range 50–1200 °C. stages determined by DSC-TG, XRD and IR–vis methods. kinetic characteristics proceeding obtained with use Kissinger model a linearized form. Compound was stable up to 280 Upon further 1200 °C, this complex sulfide underwent three main stages. first stage is ...

Barium (Ba) with CAS number 513-77-9 and atomic number 56 is a soft silvery metallic alkaline earth metal. It has a high chemical reactivity and is never found in nature as a free element. It is highly toxic upon acute and chronic exposures (Bhoelan et al., 2014). Barium has been tested for its toxicity in different studies (Llugany et al., 2000; Langdon, 1994; Akinfieva and Gerasimova, 1984). ...

OBJECTIVES/HYPOTHESIS This study tested the hypotheses that swallowing apnea duration (SAD) will increase given barium versus water, chemesthetic stimuli (i.e., water < ethanol, acid, and carbonation) mixed with barium, age (older > younger), and genetic taste differences (supertasters > nontasters). STUDY DESIGN Prospective group design. SETTING University Medical Center. METHODS Eighty ...

Barium ions enter chromaffin cells via voltage-sensitive calcium channels, although the intracellular site of barium action is distinct from that of calcium. The entry of barium primarily through voltage-sensitive channels was indicated by experiments showing inhibition of 133Ba2+ uptake by blockers of voltage-dependent calcium channels. In addition, 133Ba2+ uptake was stimulated by 50 mM KCl b...
