The Effect on Airplane Performance of the Factors That Must Be Considered in Applying Low-Drag Cowling to Radial Engines

This report presents the results of flight tests with three different airplanes using several types of low-drag cowling for radial air-cooled engines. The greater part of the tests were made with a Curtiss XF7Cc-1 (Sea Hawk) with a 410 horsepower. Wasp engine, using three fuselage nose shapes and six types of outer cowling. The six cowlings were: a narrow ring, a wide ring, a wide cowling similar in the original NACA cowling, a thick ring incorporating an exhaust collector, a single-surface cowling shaped like the outer surface of the exhaust-collector cowling, and polygon-ring cowling, of which the angle of the straight sections with the thrust line could be varied over a wide range

Case Report MRI in Diagnosis of a Giant Prostatic Utricle

A prostatic utricle cyst is an epithelial lined diverticulum arising from the prostatic urethra and usually asymptomatic when small. When enlarged, it may be symptomatic and is typically accompanied by hypospadias. We present a case of a markedly enlarged prostatic utricle in a neonate without hypospadias, demonstrated on voiding cystourethrography (VCUG), ultrasound, and 1.5 Tesla MRI
