purpose: optisol-gs is still the most popular cold storage medium used in the united states for short term preservation of donated corneas. cebi medium is a new cold storage medium made by the central eye bank of iran for donor cornea storage. this study was conducted to compare the quantitative and qualitative indices of the donated corneas maintained in optisol-gs versus in the cebi medium. m...

2014 The compression curve of CeBi up to 20 GPa was measured at room temperature by x-ray diffraction in a diamond anvil cell. Below 13 GPa, CeBi maintains its cubic structure of the NaCl-type with a bulk modulus B0 = 49.6 GPa, smaller than that reported for LaBi (B0 = 55 GPa). This anomalous lowering is attributed to a continuous increase of the cerium valence. At P = 13 GPa, CeBi undergoes a ...

--Unusual strong magnetic anisotropies in CeBi and CeSb are explained based on the anisotropic mixing mechanism between the 4f states and the valence electrons, This is consistent with the fact that no such strong anisotropy isfbund in other Ce-pnictides. Ce-pnictides are interesting materials showing various unusual anomalous properties. In CeN, Ce is believed to be tetravalency and thus non-m...

We have observed the magnetic-phase transitions of CeSb and CeBi by a magnetic circular dichroism spectroscopy in the infrared region. The phase boundary is similar to that detected by neutron scattering. The optical spectra re#ect the electronic structures in the ordered states. The electronic structure and also the origin of the magnetic transition are discussed. ( 2000 Elsevier Science B.V. ...

OBJECTIVES 1) Determine what percentage of infants outgrow regurgitation over 1 year. 2) Determine whether they develop feeding or mealtime problems. 3) Determine whether they develop frequent respiratory illnesses, including ear, sinus, and upper respiratory infections, or wheezing episodes. DESIGN One-year follow-up survey of parents of children identified at 6 to 12 months of age as those ...

CeBi has an intricate magnetic phase diagram whose fully-polarized state recently been suggested as a Weyl semimetal, though the role of $f$ states in promoting strong interactions remained elusive. Here we focus on less-studied, but also time-reversal symmetry-breaking ferrimagnetic CeBi, where our density functional theory (DFT) calculations predict additional nodes near Fermi level $E_\mathr...
