Dynamic Simulation and Characteristic Analysis of a Two-Stage Hydrogen Pressure-Reducing Valve
DesignsAs a critical component of the hydrogen supply system for fuel cells in hydrogen-powered unmanned aerial vehicles (UAVs), the dynamic performance of the two-stage hydrogen pressure-reducing valve (PRV) directly influences the stability and safety of the ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Families of children with cancer experience significant financial strain, even with universal healthcare. Indirect costs, such as productivity losses and non‐medical expenses, are rarely included in economic evaluations, and little is known about how effectively financial aid programmes alleviate this burden.

Off-axis coherently pumped laser [PDF]
, 1984 A coherently optically pumped laser system is described. A pump laser beam propagates through a laser medium contained in a degenerate cavity resonator in a controlled multiple round trip fashion in such a way that the unused pump beam emerges from an ...

, 2010 We study the pump current and noise properties in an adiabatically modulated magnetic nanowire with double domain walls (DW). The modulation is brought about by applying a slowly oscillating magnetic and electric fields with a controllable phase ...

Investigation of nonlinear absorption processes with femtosecond light pulses in lithium niobate crystals [PDF]
, 2005 The propagation of high-power femtosecond light pulses in lithium niobate crystals (LiNbO3) is investigated experimentally and theoretically in collinear pump-probe transmission experiments.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Survivors of childhood acute lymphoblastic leukemia (ALL) often exhibit early deficits in muscle and movement competence, which can compromise long‐term health. Integrative neuromuscular training (INT), a multifaceted approach combining fundamental movement activities with strength exercises, may help address these deficits during ...

Liquid pump for astronaut cooling [PDF]
, 1972 The Apollo portable life support system water-recirculation pump used for astronaut cooling is described. The problems associated with an early centrifugal pump and how these problems were overcome by the use of a new diaphragm pump are discussed ...

Model-Free Predictive Current Control of Synchronous Reluctance Motor Drives for Pump Applications
Machines, 2021 Climate changes and the lack of running water across vast territories require the massive use of pumping systems, often powered by solar energy sources. In this context, simple drives with high-efficiency motors can be expected to take hold.

, 2013 Micropumps can be classified into two general categories: mechanical and nonmechanical micropumps (an excellent review on micropumps can be found elsewhere [1]). In a typical mechanical pump, a membrane is used to produce the pumping action. Nonmechanical micropumps on the other hand generally have no moving parts.
