Suitability of a Non-Dispersive Infrared Methane Sensor Package for Flux Quantification Using an Unmanned Aerial Vehicle
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
Zr alloying effects on the microstructure, compression performance and oxidation resistance of refractory high entropy alloys
Three refractory high entropy alloys (RHEAs) with nominal compositions of Mo _0.5 NbHf _0.25 CrZr _x TiAl (x = 0, 0.5, 1, mole ratio) were prepared by vacuum non-consumable arc melting technology.The influences of Zr addition on the microstructure, compressive performance and oxidation resistance at 1473 K of RHEAs were investigated and silver lini
Coblation-assisted excision of hypopharyngeal venous malformation: a case report
Abstract Background Adult hypopharyngeal venous malformations are rare.Unlike hemangiomas, venous malformations require surgical excision wherever feasible.We describe the case of a hypopharyngeal venous malformation and use of coblation to achieve complete excision.Case presentation A 28-year-old male presented to the emergency department with sud
