ABSTRACT
Low-energy X-rays have a predominant role in medical diagnostic applications, grown tremendously during recent Covid-19 pandemic times. Synthesis of stable, PMMA/polystyrene-BiI3 composites has been done through a facile, low-cost, dry-tumble mixing technique for direct X-ray detector applications. Comparative analysis of structural, optical, and photocurrent responses upon irradiation with low-energy X-rays (30 and 60 kV) ensue that PS-BiI3 demonstrates high SNR 3300, sensitivity 189 µC Gy-1 cm-3 and fast response time 30 ms, at dose rate 1.68 mGy s-1, affirming the composite to be prospective candidate for low-energy, room-temperature, direct X-ray detectors under low bias conditions.

ABSTRACT
We report the sonographic findings of a rare case of uterine rupture with extrusion of the fetus into the broad ligament during a second-trimester abortion. Sonography revealed the empty uterus with an indistinct defect on the side wall and the dead fetus lying outside, surrounded by a thin membrane. At surgery, the uterine rupture was confirmed with the fetus lying in the broad ligament. This study shows the importance of timely sonography in second-trimester abortion, enabling immediate management and preventing further complications.
