The growing demand for nickel metal and the depletion of high-grade sulfide ore reserves have turned direction industry towards laterites which are not desirable as primary source due to their low Ni content more energy-intensive processing. Thus, alternative routes essential effectively processing these ores while reducing costs greenhouse gas emissions. Solid-state reduction followed by magne...

Schlieren imaging in wind-tunnels is extensively utilized to study the effects of air on an airplane surface. One of the interesting subjects for research is to study the effects of speed change on the airplane surface. Speed change results in occurrence of shock waves, which are visualized as lines on Schlieren images. In this paper, we study the problem of detecting speed of a plane after occ...

INTRODUCTION Primordial germ cells have an extra-gonadic origin in the chick embryo. They may be found in the primitive streak or head-process stage, in an area known as the germinal crescent, located in the endoderm anterior and antero-lateral to the primitive streak at the junction of the area opaca and area pellucida (Swift, 1914; Willier, 1937; Reynaud, 1967; Clawson & Domm, 1969). Primordi...

Two recent works have shown that at small Knudsen number (K) the pressure and temperature profiles in plane Poiseuille flow exhibit a different qualitative behavior from the profiles obtained by the Navier-Stokes equations. Tij and Santos [J. Stat. Phys. 76, 1399 (1994)] used the Bhatnagar-Gross-Kook model to show that the temperature profile is bimodal and the pressure profile is nonconstant. ...

Cluster-based and iSCSI-based storage systems rely on standard TCP/IP-over-Ethernet for client access to data. Unfortunately, when data is striped over multiple networked storage nodes, a client can experience a TCP throughput collapse that results in much lower read bandwidth than should be provided by the available network links. Conceptually, this problem arises because the client simultaneo...

Une patiente âgée de 50 ans, monophtalme de l'œil droit nous a été adressée pour une crise aigüe de glaucome par fermeture de l'angle de l'œil droit qui a évolué vers la chronicité malgré le traitement médical précoce. A j1 post trabéculectomie l'examen retrouve une hypotonie à 6 mmHg avec au du fond d'œil présence d'un œdème papillaire et de multiples hémorragies pré-rétiniennes rondes dont ce...
