The protected GEO region is defined by boundaries in inclination (-15° ... +15°) and orbit radius (± 200 km with respect to true GEO height). There are nearly 390 operational satellites with orbits inside of this zone. In addition, there are nearly 280 officially catalogued objects with orbits completely inside of the protected zone, and nearly 180 catalogued GEO satellites with orbits crossing...

The Austral ian-Antarct ic discordance zone (AAD) is an anomalously deep and rough segment of the Southeast Indian Ridge between 120 ° and 128°E. A large, negative (deeper than predicted) depth anomaly is centered on the discordance, and a geoid low is evident upon removal of a low-order geoid model and the geoid height-age relation. We investigate two models that may explain these anomalies: a...

results out of 617 patients, 79.6% had 21-hydroxylase deficiency (21-ohd). in 21-ohd group 94.5% had classical type and 5.5% were non-classic. among the classic type 78% had salt-wasting form (sw) and 22% simple virilizing (sv). both 21-ohd-sv and sw were diagnosed more frequently in females. frequency of other types were as follow: 11-hydroxylase deficiency (11-ohd), 13.3%; 3ß-hydroxysteroid d...

In the present work, combustion of vitiated hydrogen jets issuing from differently shaped nozzles is modelled using LES method. We investigate impact nozzle cross-sectional geometries (circular, square, triangular, hexagonal and hexagram) jet Reynolds numbers (Re= 18,000, 20,000 23,600) on flame lift-off height, its structure, locations temperature maxima species distributions. The triangular y...

The number of lifters of mill shell liners, mill rotation speed, and filling percentage of grinding media are three of the most important parameters influencing the charge behavior and the trajectory of ball motion inside the SAG mills, and consequently, their performance. In this paper, the milling operation of pilot-scale SAG mills using the discrete element method (DEM) is investigated. Firs...
