This study describes the development of a simple and easy-to-build portable automated bag valve mask (BVM) compression system, which, during acute shortages and supply chain disruptions can serve as a temporary emergency ventilator.The resuscitation system is based on the Arduino controller with a real-time operating system installed on a largely R
Introduction: Implementing HIV iphone 14 price san francisco pre-exposure prophylaxis in the U.S.is critical to decreasing HIV transmission.However, regional disparities in pre-exposure prophylaxis use exist, with the southern U.S.having the lowest uptake relative to need.Community-based organizations in the South provide pre-exposure prophylaxis t
Point-source methane emission flux quantification is required to help constrain the global methane budget.Facility-scale fluxes can be derived using in situ methane mole fraction sampling, near-to-source, which may be acquired from an unmanned aerial vehicle (UAV) platform.We test a new non-dispersive infrared methane sensor by mounting it onto a s
