Precise measurement of methane in air using diode-pumped 3.4-μm difference-frequency generation in PPLN
Fast, accurate measurement of the methane mixing ratio in natural air samples using a compact solid-state 3.4-μm difference-frequency spectrometer is reported. The spectrometer employed bulk periodically poled lithium niobate (PPLN) pumped by a solitary diode laser at 808 nm and a diode-pumped monolithic ring Nd:YAG laser at 1064 nm, and a 300 cm3 volume multi-pass absorption cell with an 18m p...
متن کاملdesign and fabrication of an exprerimental model of a seeding unit with widthwise sugarcane scions seeding for use in sugarcane planter
introduction sugarcane, a plant which sugar is extracted from, is planted in vast areas with hot and humid climate. brazil is the largest producer of sugarcane in the world. the next five major producers, in decreasing order, are india, china, thailand, pakistan and mexico. sugarcane is a tropical, perennial grass that forms lateral shoots at the base to produce multiple stems, typically three ...
متن کاملA test of the air-seeding hypothesis using sphagnum hyalocysts.
"Air-seeding" is a proposed mechanism for the initiation of water stress embolism in dead plant cells. During air-seeding, external air is drawn into the lumen of a dead plant cell through a pore or crack in the cell wall. The resulting bubble may expand to fill the lumen, thus embolizing the cell. The data presented confirm that Sphagnum hyalocysts can embolize by air-seeding when the pressure...
متن کاملConcept Investigation via Air-Ground Simulation with Embedded Agents
Next Generation Air Transportation System (NGATS) concepts require design and analysis of interactions involving human operators and new automation tools. Research is exploring how air-ground simulations with embedded agents can complement human-in-theloop simulations for this purpose. This paper describes research toward integrating computational air traffic controller agents into a large-scal...
