OBJECTIVE
To develop three grading scales for objective assessment of the infraorbital hollow and upper and lower cheek fullness and to establish the reliability of these scales for clinical research and practice.
METHODS AND MATERIALS Three 5-point rating scales were developed to assess infraorbital hollow and upper and lower cheek fullness objectively. Twelve experts rated identical mid face photographs of 50 subjects in two separate rating cycles using the mid face scales. Test responses of DAPT nmr raters were analyzed to assess intra-and interrater reliability.
RESULTS Interrater reliability was substantial for the infraorbital hollow, upper cheek fullness, and lower cheek fullness scales. Intrarater reliability was high for all three scales. Both of the cheek fullness
scales yielded higher reliabilities when three rather than two views were used to assess the volume changes of the cheek.
CONCLUSION The mid face scales are reliable tools for valid and reproducible assessment of age-related mid face changes.”
“MgxZn1-xO (x=0.15) and ZnO nanocrystals of about 40 nm in diameter were studied using x-ray diffraction and diamond-anvil cells. The equation of state (EOS) for MgZnO is reported for the first time. Between pressures of 9.45 and 10.7 GPa, MgZnO transforms into the rocksalt (NaCl) structure, which persisted to 1.1 GPa upon CHIR-99021 decompression. The EOS parameters for ZnO are close to their bulk values and in good agreement with values obtained previously. The bulk modulus for MgZnO was Adriamycin mouse slightly lower than that of ZnO. The pressure-induced decrease in c/a ratio was greater for MgZnO, consistent with the tendency for MgZnO to move toward a cubic structure. From previous photoluminescence measurements [J. Huso , Appl. Phys. Lett. 89, 171909 (2006)],
the band-gap volume deformation potentials for ZnO and Mg0.15Zn0.85O were determined to be -3.6 and -4.0 eV, respectively.”
“Aqueous deposited copolymerization reaction is of acrylonitrile (AN) with itaconic acid (IA) were carried out in deionized water at 60 degrees C with a single watersoluble initiator. High-molecular-weight polyacrylonitrile (P, N) copolymers were acquired by adjustment of technical polymerization parameters. When the amount of IA in the feed reached 2 wt %, the conversion of the polymrization reaction, intrinsic viscosity, and viscosity-average molecular weight all achieved their maximum values, whereas the molecular weight distribution achieved its minimum value. The AN/IA reactivity ratios, calculated with Q-e schemes (where Q and e are measures of the reactivity and polarity, respectively), agreed well with those determined with the Fineman-Ross and Kelen-Tudos methods.
