Cubic BaTiO3 particles of∼10 nm were crystallized predominantly within the hydroxylated polybutadiene matrix of a phase separated triblock copolymeric thin film of polystyrene-polybutadiene-polystyrene (Kraton D1102). The barium titanated Kraton thin film had remnants of the cylindrical morphology of a plain Kraton thin film with an interdomain spacing of ∼23 nm. The procedure of barium titanat...

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 ...

A 35-year-old man presented with a 10-day history of recurrent crampy abdominal pain, distension, nausea, vomiting and alternating constipation and diarrhea. His medical history was significant for an appendectomy, done many years earlier. Physical examination revealed dehydration and some abdominal distension but no visible external hernia. Smallbowel follow-through with barium and intraoperat...

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...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2014208495 DESCRIPTION An 86-year-old man presented to accident and emergency with symptoms and signs of a lower respiratory tract infection. He had a history of severe dysphagia and regurgitation of food associated with two-stone weight loss and a significant reductio...

A spectrophotometric method was developed for ascorbic acid present in various fruits, commercial fruit juices and sprouted food grains. The method involves the oxidation of ascorbic acid with excess manganese(III) following reduction of unreacted manganese(III) with diphenylamine or barium diphenylamine sulphonate forming a product λ(max) 570 nm the system 1 or 540 nm the system 2 and decrease...

The absolute magnitude of barium stars has been obtained from kinematical data using a new algorithm based on the maximum-likelihood principle. The method allows to separate a sample into groups characterized by different mean absolute magnitudes, kinematics and z-scale heights. It also takes into account, simultaneously, the censorship in the sample and the errors on the observables. The metho...

Higher cardiovascular mortality has been associated in a single epidemiological study with higher levels of barium in drinking water. The purpose of this study was to determine whether drinking water barium at levels found in some U.S. communities alters the known risk factors for cardiovascular disease. Eleven healthy men completed a 10-week dose-response protocol in which diet was controlled ...
