many studies have considered the effects of suspension properties on the dewatering process but fewhave focused on ore properties. thus, the present work studied the effects of ore properties (density,particle size, mineralogy) on the dewatering process based on lab and pilot experiments. a hydrocyclonewas used to prepare the required samples for the experiments. to study the effects of mineral...

spinal epidural haemorrhage may present as back pain associated with radicular symptoms and can be a catastrophic clinical scenario with progression to paraplegia or even sudden death. being a rare entity, it needs a high index ofclinical suspicion to diagnose it. fractures have been documented as a cause of hematorrachis but such hematomas only extend to one or two vertebral segments. large ep...

a 19-year-old man presented with a 5-year history of back pain radiating to the lower extremities and paresthesis of the toes during the last year. plain x-ray revealed a large cauliflower shaped exophytic mass at the level of t8, t9 and t10 vertebrae. computed tomography (ct) and magnetic resonance imaging (mri) showed an abnormal bony mass arising from the posterior arch of t9 with protrusion...

The etiology of rotator cuff tendinopathy is multi-factorial, and has been attributed to both extrinsic and intrinsic mechanisms. Extrinsic factors that encroach upon the subacromial space and contribute to bursal side compression of the rotator cuff tendons include anatomical variants of the acromion, alterations in scapular or humeral kinematics, postural abnormalities, rotator cuff and scapu...

The purpose of this investigation is to characterize nevirapine from commercial samples and samples crystallized from different solvents under various conditions. The solid-state behavior of nevirapine samples was investigated using a variety of complementary techniques such as microscopy (optical, polarized, hot stage microscopy), differential scanning calorimeter, thermogravimetric analysis, ...

In this work, the stability of hypersonic flow over a curved compression ramp is studied using several analysis tools and direct numerical simulations (DNS). The free-stream Mach number unit Reynolds are 7.7 $4.2 \times 10^6$ m $^{-1}$ , respectively. Corner rounding considered to alter separation bubble so as suppress intrinsic instability compression-ramp flow. variation confirmed by global a...

UNLABELLED The number of human genomes that have been sequenced completely for different individuals has increased rapidly in recent years. Storing and transferring complete genomes between computers for the purpose of applying various applications and analysis tools will soon become a major hurdle, hindering the analysis phase. Therefore, there is a growing need to compress these data efficien...

Introduction UN lesions in the wrist and hand can cause a variety of different clinical findings, depending on precise location. Findings might range from a pure sensory deficit to pure motor syndromes with weakness that may or may not involve the hypothenar muscles. This depends on whether the lesion involves the main trunk, the sensory branch only, or the deep palmar branch at different sites...

Pressure induced conformational and phase transformations of chlorocyclohexane (CCH) were investigated in a diamond anvil cell by Raman spectroscopy at room temperature. Pure CCH was compressed up to 20 GPa and then decompressed to ambient pressure. The conformational equilibrium was shifted by pressure from equatorial to axial conformers in the fluid phase below 0.7 GPa, consistent with previo...

The vertebral artery (VA) is an important vessel supplying the hind brain; its surgical exposure and control is usually considered a great challenge. In fact, with good knowledge of surgical anatomy and proper surgical technique, the VA can be controlled and occasionally repaired with safety and reliability. VA exposure is useful in many instances and helps attain better results in the surgical...
