background: endotracheal suctioning (ets) is one of the most common supportive measures in intensive care units (icu). ets may be associated with complications including hypoxia and tachycardia. closed system suctioning (css) decreases the rate of cardiorespiratory complication mainly due to continuation of ventilatory support and oxygenation during procedure. css has questionable efficacy, the...

The chemical composition of pore fluid and matric suction rule the mechanical behaviour soils. In case clays, their fabric changes in line with those variables. Since both increase salinity cause a transition from an open to close microstructure low medium activity clayey materials, unique framework could tackle problems where saturation are expected. This paper presents simple elasto-plastic m...

This paper presents the study of the effects of variable thermal conductivity and Darcy-Forchheimer on magnetohydrodynamic free convective flow in a vertical channel in the presence of constant suction. The resulting governing equations are non-dimensionalised, simplified and solved using Crank Nicolson type of finite difference method. To check the accuracy of the numerical solution, steady-st...

Research on suction-feeding performance has mostly focused on measuring individual underlying components such as suction pressure, flow velocity, ram or the effects of suction-induced forces on prey movement during feeding. Although this body of work has advanced our understanding of aquatic feeding, no consensus has yet emerged on how to combine all of these variables to predict prey-capture p...

OBJECTIVES To evaluate the safety of an ozone gas device designed for use in dentistry. METHODS Two commercially available ozone applicators, Ozi-cure and HealOzone were used in a clinical simulation using a phantom head while recordings of ozone levels were made in pharyngeal and nasal regions of the patient and near the mouth of the operator. Clinical simulations included ozone application ...

This paper deals with the behavior of unsteady MHD Micropolar flow and Mass transfer past a vertical plate with variable suction. The resultant equations are solved analytically using Perturbation method. The analytical expressions for the velocity profiles, temperature profiles and concentration profiles of the fluid have been obtained with the help of the material parameters such as Grashof n...
