Using electromagnetic levitation in combination with the oscillating drop technique and drop calorimeter method, the surface tensions and specific heats of undercooled liquid Co-10 wt% Mo, Co-26.3 wt% Mo, and Co-37.6 wt% Mo alloys were measured. The containerless state during levitation produces substantial undercoolings up to 223 K , 213 K and 110 K respectively for these three alloys. In their respective undercooling ranges, the surface tensions were determined to be 1895 m 0.31, 1932 m 0.33, and 1989 m 0.34 (...) mN m m 1 . According to the Butler equation, the surface tensions of these three Co-Mo alloys were also calculated, and the results agree well with the experimental data. The specific heats of these three alloys are determined to be 41.85, 43.75 and 44.92 J mol m 1 K m 1 . Based on the determined surface tensions and specific heats, the changes in thermodynamics functions such as enthalpy, entropy and Gibbs free energy are predicted. Furthermore, the crystal nucleation, dendrite growth and Marangoni convection of undercooled Co-Mo alloys are investigated in the light of these measured thermophysical properties. (shrink)

L'A. examine ici le regard que la philosophie porte sur la Bible. Pour ce faire, il ne s'intéresse qu'au sacrifice d'Abraham et il observe ce qu'en disent des philosophes comme Hegel ou Kant. A leur attitude réprobatrice, l'A. oppose celle de Sören Kierkegaard et de son ouvrage Crainte et tremblement. Celui-ci fait d'Abraham un intrépide chevalier de la foi qui abolit le chevalier tragique et résigné. Il en va tout autrement chez Kafka, Raïssa Maritain et Giulio Lequier dont l'A. rapporte (...) fidèlement les écrits consacrés à Abraham. (shrink)

Motivation and perspective for an exciting new research direction interconnecting logic, spacetime theory, relativity--including such revolutionary areas as black hole physics, relativistic computers, new cosmology--are presented in this paper. We would like to invite the logician reader to take part in this grand enterprise of the new century. Besides general perspective and motivation, we present initial results in this direction.

Class line is a fundamental line of the Party. To be the Communist Party is to make revolution, eradicate the bourgeoisie and promote the proletariat, stress class status, and implement the proletarian class line!
