Seed germination requirements may determine the kinds of habitat in which plants can survive.We tested the hypothesis that nitrogen (N) addition can change seed germination trait-environmental filter interactions and ultimately redistribute seed germination traits in alpine meadows.We determined the role of N addition on germination trait selection
Posterior circulation involves the vertebrobasilar arteries, which supply oxygen and glucose to vital human brainstem structures and other areas.This complex circulatory- perfusion system is not homogenous throughout the day; rather, its hemodynamic changes rely on physiological demands, ensuring brainstem perfusion.This dynamic autoregulatory patt
In order to study the effect of wheel harmonic wear on train operation safety, the simulation model of train-track-subgrade coupling system which considered rail and track plate vibration was established.According to the harmonic order of the first-order, sixthorder and eleventh-order in the wave depth of 0.1 mm and Grill / Top Oven Element 0.3 mm,
A wave energy converter (WEC) based on a direct mechanical drive system Speed Sensor Bracket (DMDS) exhibits limited performance when the sea state stands for a short period.This study aims to increase the efficiency of a WEC-DMDS mechanical system applied under short-wave conditions.A novel WEC is designed by applying cascaded gear and reducing th
