THE INFLUENCE OF THE TANGENTIAL VELOCITY OF INNER ROTATING WALL ON AXIAL VELOCITY PROFILE OF FLOW THROUGH VERTICAL ANNULAR PIPE WITH ROTATING INNER SURFACE

In the oil and gas industries, understanding the behaviour of a flow through an annulus gap in a vertical position, whose outer wall is stationary whilst the inner wall rotates, is a significantly important issue in drilling wells.The main emphasis is placed on experimental (using an available rig) and computational (employing CFD software) investi

Viral infections LIP TINT provoke dysbalance in the interferon system and inhibition of the cellular and phagocytic responses of the host.Long-term persistence of pathogenic viruses and bacteria induce atopy and could aggravate chronic respiratory diseases.The up-to-date classification of immunomodulators is described.High efficacy of interferon in

Peptide Lv is a small endogenous secretory peptide that is expressed in various tissues and conserved across different species.Patients with diabetic retinopathy, an ocular disease with pathological angiogenesis, have upregulated peptide Lv in their VISION FACTORS retinas.The pro-angiogenic activity of peptide Lv is in part through promoting vascul

The Virtual Resistor based Active Damping (VR-AD) is widely employed in converters connected to the grid via LCL filters in order to mitigate the inherent resonance of the filters.Nevertheless, in digitally controlled systems, the PWM and the calculating delays modify 5 Inch the system characteristics in terms of frequency and phase, thus destabili

The concept of social capital has received increasing attention in recent years.The complexity and multidimensionality that accompany the variable of social capital have Treatments caused confusion and ambiguity.This article presents a synthesis of social capital in three perspectives.From the individualistic or micro-social perspective, social cap
