Somogyi's (6) blood sugar method is one of the most reliable and extensively used method for the estimation of true sugar. Non-sugar reducing substances of blood are located principally in the erythrocytes (3) and are removed from laked blood by adding barium hydroxide and zinc sulphate solution in this method (5). Unfortunately solutions of barium hydroxide are very susceptible to deterioratio...

Eight new barium methylphosphonates were prepared and described. In dependence on pH, either barium hydrogen methylphosphonates or barium methylphosphonates can be formed. In the case of barium methylphosphonates, BaCH3PO3·3H2O crystallizes from the solution at room temperature and BaCH3PO3·H2O at a temperature above 65 °C. On heating, these hydrates form two anhydrous barium methylphosphonates...

Factor VII purified as previously described, was found to consist of two polypeptide chains joined by disulfide bridges. We now report the isolation and 200,000-fold purification of a single chain form of Factor VII. This was accomplished by protecting the molecule against proteolysis by including benzamidine during the entire purification. The purification was essentially as previously reporte...

We have produced sympathetically cooled barium monohalide ions BaX+ (X = F, Cl, Br) by reacting trapped, laser-cooled Ba+ ions with room-temperature gas-phase neutral halogen-containing molecules. Reaction rates for two of these (SF6 and CH3Cl) have been measured and were found to be in agreement with classical models. BaX+ ions are promising candidates for cooling to the rovibrational ground s...

Dielectric elastomers (DEs) are being exploited for biological applications such as artificial blood pumps, biomimetic grippers and biomimetic robots. Generally, polyacrylate and silicone rubber (SR) are the most widely used materials for fabricating DEs in terms of mixing with other polymers or compounding them with highly dielectric particles. Furthermore, pre-stretch offers an effective appr...

Background and Aims. We initiated peroral endoscopic myotomy (POEM) utilizing a two-person technique with combination of an advanced endoscopist and a thoracic surgeon with complementary skills. Our aim was to determine the feasibility and outcomes in initial 20 patients. Methods. In this observational study, main outcomes measured were therapeutic success in relieving symptoms (Eckardt score <...

∑ Few subspecialty fields in radiology have undergone so many changes in the last several decades as has gastrointestinal (GI) radiology. We have witnessed the appearance of previously unknown or very uncommon diseases and observed changes in the prevalence and treatment of known diseases. In the clinical setting, abdominal radiology had a seminal role in evaluating these conditions. Scientific...

Nanocomposites with nanofillers of reactive montmorillonite covalently-bonded with barium titanate G. Polizos, V. Tomer, E. Manias, and C. A. Randall Polymer Nanostructures Laboratory, Center for the Study of Polymeric Systems (CSPS) and Department of Materials Science and Engineering, The Pennsylvania State University, University Park, Pennsylvania 16802, USA Center of Dielectric Studies (CDS)...

Barium ferrite thin films with perpendicular c-axis orientation and small grain size ~about 300 Å! were successfully fabricated with careful control of sputtering conditions. The c-axis orientation of barium ferrite thin films is most sensitive to the oxygen partial pressure during deposition. All samples with oxygen gas during deposition have a random c-axis texture, as indicated by existence ...

The rheological properties of two non-polar liquids [silicone oil or perfluorinated oil (FC70)] containing various types of particles, barium titanate, nickel and iron-oxide, were investigated as functions of solid loading, particle size and shear rate. All the particles were synthesised in-house. The viscosities of either silicone oil or FC70 containing different solid loadings (10, 20 and 30 ...
