The accurate prediction of the aeroelastic behavior of turbomachinery for aircraft propulsion poses a difficult yet fundamental challenge, since modern aircraft engines tend to adopt increasingly slender blades to achieve a higher aerodynamic efficiency, incurring an increased aeroelastic interaction as a drawback.In the present work, we present a
In yellow shirt relics order to better implement the water environmental management policies, water quality evaluation is the basic step, that is to reasonably divide it into specific water quality category according to multiple water quality parameters in a certain water area.Aimed at this problem, an improved Naive Bayes classification method was
Background: How to manage patients, transmission times, and therapeutic measurement executed during air transmission can improve training, protocols, and management decisions.The current study aimed at investigating the dispatch criteria and the way of handling patients during transport by air emergency medical services of Kurdistan Province, Iran,
Various organic and inorganic mulches are used for soil conservation purposes, the effectiveness of which on soil characteristics has not been comprehensively considered from different aspects.The present c12a microphone study surveys the efficiency of straw mulch, manure and TA-200 polyacrylamide with respective rates of 500, 300 and 50 g m−
Failures may result from a variety of mechanical issues, including the improper composition of the components.This study synthesizes specific typical varying materials, including nylon 6/6 and glass fibers, with unique volume proportions to improve abrasion resistance and extend the lifespan of equipment.The research demonstrated that polymer gears
