The ring current growth and decay, characterized by the Dst index, has been studied for thirty years using the Burton et al. (1975) equation. The original formula is based on the restriction of the DPS (Dessler, Parker, and Schoppke) theorem and as

Relationships between characteristic parameters of geomagnetic storms like the pressure corrected Dst index ( Dst ⁎ ), the solar wind speed, the southward component of the interplanetary magnetic field B S , and their associated times were studied

Magnetic storms are caused by changes in the currents flowing near the Earth, particularly by the enhanced ring current. The ring current dynamics is described through the energy balance equation, where a key role is played by the decay time paramete

Nonenhanced and gadolinium-enhanced fat-suppressed spin-echo and breath-hold fast low-angle shot (FLASH) magnetic resonance (MR) imaging techniques were compared with iodine contrast material-enhanced computed tomography (CT) for the detection and ch

A woman was referred at 25 weeks' gestation with decreased fetal movements. Ultrasound revealed a large solid fetal abdominal mass and gross fetal ascites. Amniocentesis and viral titers were normal. On subsequent ultrasound examinations, the mass an

In an attempt to resolve the question of the relative contributions of hydrodynamic pressure and infection to the pathogenesis of reflux nephropathy, we studied the pathologic changes in 46 kidneys subjected to vesico-ureteral reflux and obtained at

Recent reviews of meconium ileus (MI) in cystic fibrosis (CF) have documented reduced mortality when compared to earlier studies but suggest significant morbidity is still present, with feeding difficulties and prolonged hospital admission. A chart r

Cells with the characteristic features of carcinoma in situ (CIS) were detected in histological sections of the gonads of three of seven children with clinical syndromes associated with a high risk of gonadal neoplasia. It is suggested that early det
