THE INFLUENCE OF MELT CONVECTION ON DENDRITIC SPACING OF DOWNWARD UNSTEADY-STATE DIRECTIONALLY SOLIDIFIED SN-PB ALLOYS

The influence of melt convection on dendritic spacing of downward unsteady-state directionally solidified Sn-Pb alloys

Microstructures are the strategic link between materials processing and materials behavior.A dendritic structure is the most frequently observed pattern of solidified alloys.The microstructural scales of dendrites, such as primary and secondary arm spacings, control the segregation profiles and the formation of secondary phases within interdendriti

Impact of multimodality in reading comprehension of narrative texts in English as a foreign language (EFL) in undergraduate students

This research seeks to compare the effect that monomodal and multimodal tests have on the reading comprehension level of English-written narrative texts Stoppers that EFL learners achieve at a private Chilean university.For this purpose, a quasi-experiment was performed, using a monomodal reading comprehension test and another multimodal one, with

Sequential endoscopic and robot-assisted surgical solutions for a rare fungal spondylodiscitis, secondary lumbar spinal stenosis, and subsequent discal pseudocyst causing acute cauda equina syndrome: a case report

Abstract Background Fungal spondylodiscitis is a rare infectious disease.The secondary lumbar spinal stenosis and Sunglasses postoperative discal pseudocyst were even rarer.The surgical interventions were disputed, yet endoscopic and robot-assisted techniques may be helpful under different circumstances.Case presentation A 62-year-old female was di
