The cladding pumping within a double-clad fiber structure is an effective technique to convert high-power multimode beam into high-power, almost diffraction limited beam.Since the pump efficiency is limited s?n nhà màu n?u ??t by the presence of higher skew-ray modes, geometrical perturbations are used to scramble the modes and to achieve a highe
Porous Copper (Cu) was brazed to Cu plates using Cu-9.7Sn-5.7Ni-7P amorphous filler metal.The effects of brazing parameters on the porous Cu and brazed joints were investigated.The furnace brazing temperatures employed were 660 °C and 680 °C, and the holding times were 10 and 15 min.After brazing, the microstructure was analyzed using Sca
Prediction of air quality metrics is a multidomain task that involves analysis of different inter-related parameters.These parameters include, type of location, NO2 levels, SO2 levels, Respirable Suspended Particulate Matter (RSPM) levels, Fine particulate matter (PM2.5) levels, etc.Researchers have proposed a wide variety of models to predict air
A potentially more environmentally compatible approach was evaluated, involving the use of an enzyme (X) stage optimally inserted into various bleaching sequences for Eucalyptus kraft pulps.The efficacy of the X stage was evaluated in terms of final brightness, CIE whiteness, post-color number (brightness reversion), effluent characteristics, etc.T
Avulsion of the lesser trochanter is a rare but disturbing condition, which usually occurs in males between the ages of 7-16 years with significant physical activities or in athletes.Diagnosis is more often than not challenging, but with ssl pure drive quad a good history, physical examination, and imaging modality, diagnosis can be clinched, and t
