Somatostatin and ranitidine in the treatment of non-variceal upper gastrointestinal bleeding: A prospective, randomized, double-blind, controlled study

Background/Aims: The aim of this study was to compare the efficacy of somatostatin vs. ranitidine in controlling acute non-variceal gastrointestinal bleeding

Determination of Interfacial Energies for Solid Al Solution in Equilibrium with Al-Cu-Ag Liquid

WOS: 000277712900008The 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-4.97 at.% 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.Scientific and Technical Research Council of Turkey (TUBITAK) [105T481]This research was financially supported by the Scientific and Technical Research Council of Turkey (TUBITAK under Contract No: 105T481).

Thermal conductivity and interfacial energies of solid Sn in the Sn-Cu alloy

WOS: 000273051800027The equilibrated grain boundary groove shapes of solid Sn in equilibrium with the Sn-Cu eutectic liquid were observed from a quenched sample. The Gibbs-Thomson coefficient, solid-liquid interfacial energy and grain boundary energy of solid Sn have been determined to be (8.7 +/- 0.6) x 10(-8) Km, (113.1 +/- 13.6) x 10(-3) J m(-2) and (222.4 +/- 28.9) x 10(-3) J m(-2), respectively. The thermal conductivity of solid phase and the thermal conductivity ratio of liquid phase to solid phase for Sn-1.3 at.%Cu alloy have also been measured with radial heat flow apparatus and Bridgman type growth apparatus, respectively.
