Bulk Density of Lactose Powders Under Low Consolidation Stresses

In the food and pharmaceutical industries, the shear testing protocol developed by Jenike in 1964 has been commonly used to characterize powder flow. The protocol requires the measurement of the stress required to shear a powder bed under a series of normal consolidation stresses and the consolidated bulk density. In this work, we report the bulk density of thirteen milled lactose powders of di...

Meniscal Extrusion in the Knee: Should only 3 mm Extrusion be Considered Significant? An Assessment by MRI and Arthroscopy

AIM The aim of this study was to assess whether significant meniscal extrusion of more than 3 mm or of even lesser degrees of extrusion could be considered significant. We also aimed to determine the morphology of tears that are most likely to be associated with significant extrusion. Study design and material. The study was done retrospectively on a group of 202 patients (157 males and 45 fema...

The crystallization process of amorphous Al80Fe20 alloy powders prepared by ball milling

The amorphous-to-crystalline transition during thermal annealing of amorphous Al80Fe20 alloy powders prepared by ball milling was investigated by means of magnetothermal analysis and X-ray di€raction. Following structural relaxation and stress relief processes, a metastable phase precipitates during primary crystallization, and a mixture of intermetallic compound (h-Al13Fe4) and fcc Al is devel...

Synthesis of HfB2 Powders by Carbothermal Reduction

In this research, solid state carbothermal synthesis of HfB2 Nano powders was investigated. For this purpose, HfO2,H3BO3, carbon active or phenolic resin were used as raw materials for carbothermal reaction. After 2-4 hours of milling the raw materials by a planetary ball in an ethanol media, the mixture was heat dried and pressed in to disks under pressure of 20-30 bar. The disks were then pla...
