Considerable strides have been made in reducing the rate of perinatal human immunodeficiency virus (HIV) transmission within United States and around globe. Despite this progress, preventable HIV continues to occur. Adherence screening treatment recommendations preconception during pregnancy can greatly reduce risk transmission. Early consistent usage highly active antiretroviral therapy (ART) lower viral load, thus minimizing risk. Additional intrapartum interventions further Although...

Abstract Changing well control requirements have increased accumulator volumes for the operation of Blow Out Preventer (BOP) stacks and diverters, challenging space available BOP system equipment on today's rigs. Koomy or Land Closing Units (LCUs) use potential energy stored in accumulators to hydraulically actuated Stack diverter systems. Accumulator systems are limited their operational capacity because inefficiencies created by rapid adiabatic gas expansion pressure flow decay over...

A Blowout Preventer (BOP) serves as a safety valve in the drilling process oil and gas industry. It will be closed if an influx of formation fluids occurs threatens rig. Ram BOP is one type widely used BOP. composed two ram blades, which move toward each other to shear pipe close valve. To ensure shearing completed on rig, lab tests are often run evaluate BOP’s capability required pressure.
