Determination of Interfacial Energies for Solid Al Solution in Equilibrium with Al-Cu-Ag Liquid
K. Ke lio lu,Y. Ocak,S. Aksöz,N. Mara ll,E. Çadlrll,H. Kaya 대한금속·재료학회 2010 METALS AND MATERIALS International Vol.16 No.1
The equilibrated grain boundary groove shapes of a solid Al solution in equilibrium with Al-Cu-Ag liquid were observed from a quenched sample using a radial heat flow apparatus. The Gibbs-Thomson coefficient,solid-liquid interfacial energy, and grain boundary energy of the solid Al solution were determined from the observed grain boundary groove shapes. The thermal conductivity of the solid phase for Al-16.42 at.% Ag-4.97at.% Cu and Al-16.57 at.% Ag-11.87 at.% Cu alloys and the thermal conductivity ratio of the liquid phase to the solid phase for Al-16.57 at.% Ag-11.87 at.% Cu alloy at the melting temperature were also measured with a radial heat flow apparatus and a Bridgman-type growth apparatus, respectively.

Angular correlations between charged trigger and associated particles are measured by the ALICE detector in p-Pb collisions at a nucleon-nucleon centre-of-mass energy of 5.02 TeV for transverse momentum ranges within 0.5<p<SUB>T,assoc</SUB><p<SUB>T,trig</SUB><4 GeV/c. The correlations are measured over two units of pseudorapidity and full azimuthal angle in different intervals of event multiplicity, and expressed as associated yield per trigger particle. Two long-range ridge-like structures, one on the near side and one on the away side, are observed when the per-trigger yield obtained in low-multiplicity events is subtracted from the one in high-multiplicity events. The excess on the near-side is qualitatively similar to that recently reported by the CMS Collaboration, while the excess on the away-side is reported for the first time. The two-ridge structure projected onto azimuthal angle is quantified with the second and third Fourier coefficients as well as by near-side and away-side yields and widths. The yields on the near side and on the away side are equal within the uncertainties for all studied event multiplicity and p<SUB>T</SUB> bins, and the widths show no significant evolution with event multiplicity or p<SUB>T</SUB>. These findings suggest that the near-side ridge is accompanied by an essentially identical away-side ridge.

Objective This study aims to assess the psychometric values of the Generalized Anxiety Disorder Scale-Revised (GADS-R) which measures the intensity and duration of worry, various coping and avoidance strategies to cope with worrying, and positive and negative metacognitive beliefs about worrying. Methods 114 patients with generalized anxiety disorder and 198 healthy controls were included in the study. These patients were diagnosed according to DSM-IV TR, and the primary diagnosis of the patients was generalized anxiety disorder which was confirmed via SCID I and II, subsequently. Sociodemographic form, GADS-R total and subscale scores, and Meta-Cognitions Questionnaire-30 (MCQ-30), Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Generalized Anxiety Disorder-7 Scale (GAD-7), and Penn State Worry Questionnaire (PSWQ) were used to assess validity, reliability and cut-off point. Results GADS-R total and subscale scores and MCQ-30, BDI, BAI, GAD-7, and PSWQ were found to be statistically higher in the patients with GAD compared to a healthy control group. GADS-R has five factors and showed relatively acceptable sensitivity and specificity for detecting anxiety disorders at a cut-off point of 1188. Conclusion The GADS-R is a valid and reliable scale that can be used in the Turkish population as an assessment tool.
