The strength of the stratospheric wave driving during northern winter is often quantified by the January–February mean poleward eddy heat flux at 100 hPa, averaged over 40°–80° N (or a similar area and period).Despite the dynamical and chemical relevance of the wave driving, the causes for its variability are still not well unde
Unlike its predecessor studies, this paper investigates the contemporaneous and lagged effects of institutional variables on tax performance, using unbalanced panel data from 79 developing countries for the 2002-2019 period.The instrumental variable (IV) and system-generalized method of moments (SGMM) estimation models were employed in this study t

AbstractA 13-year-old girl was admitted for headache, right periorbital swelling and erythema.CT imaging Dryer Motor Mounts demonstrated right orbital preseptal cellulitis, severe pansinusitis and suspected epidural abscess.Brain MRI and sinus CT confirmed an epidural abscess in the right middle cranial fossa and Bolero Hat a second extra-cranial a
Aiming at Dryer Filter the difficulty in locating and identifying the faults of oil-immersed transformers, a new spherical submersible transformer inspection robot is designed.The robot has a spherical structure with a zero turn radius, which ensures its flexible motion.It is a difficult problem for the underactuated spherical robot to realize the
