The gastric distribution of barium sulphate and its subsequent intestinal passage were examined by radiography in Potorous tridactylus. Barium sulphate administered in association with solid food passed to the sacciform forestomach from the tubiform forestomach. However, ingested barium sulphate suspension mainly entered the hindstomach via the gastric sulcus. Barium sulphate which entered the ...

The essence of adsorbents in water or wastewater treatment cannot be over-estimated. This research paper seeks to investigate the characterisation river sand, beach sand and granite as treatment. River (collected some localities Nigeria) were sieved, washed later sun-dried. These three materials taken laboratory for XRF, SEM EDX analyses. XRF analysis revealed that oxides present selected inclu...

Environmental barrier coatings (EBCs) are used in commercial turbine engine applications as protection for ceramic matrix composites, yet the high-temperature water vapor reaction mechanism EBC materials is not fully understood. Here, barium strontium alumino-silicate (BSAS), an early generation candidate, was determined from time and temperature dependences of material loss. BSAS exposures wer...

The effect of low concentrations of barium on the membrane properties of rat neocortical neurons was studied in vitro. Potassium currents were examined using single-electrode current- and voltage-clamp techniques. Neurons responded to bath application of barium (10-100 microM) with a membrane depolarization associated with an increase in input resistance. Under voltage clamp conditions, an inwa...

PURPOSE Nutrients and immunological factors of breast milk are essential for newborn growth and the development of their immune system, but this secretion can contain organic and inorganic toxins such as barium. Colostrum contamination with barium is an important issue to investigate because this naturally occurring element is also associated with human activity and industrial pollution. The st...

in the present work, the synthesis of barium hexaferrite (bafe12o19) nanoparticles in thepresence of a large excess amount of oh− anions by the hydrothermal method in the presence and absence of surfactants such as sodium dodecyl benzene sulfonate and triton x-114 was reported. the optimized temperature in the absence of surfactant was determined (200 °c) and then barium hexaferrite nanoparticl...

We refine a technique used by B. Boyce to change the carrier concentration level of thin YBa2Cu3O7-δ (YBCO) films. The purpose of this is to eventually study the superconductor to insulator transition that takes place in YBCO as carrier concentration level decreases. Introduction. For high carrier densities, YBCO is a d-wave superconductor, and its superfluid density has either a linear or a qu...
