[1] Ring-mold craters (RMCs), concentric crater forms shaped like a truncated torus and named for their similarity to the cooking implement, are abundant in lobate debris aprons (LDA) and lineated valley fill (LVF) in the northern mid-latitudes on Mars, but are not seen in surrounding terrain. LDA and LVF have been interpreted to form by flow of debris, but uncertainty remains concerning the me...

BACKGROUND In diagnostic radiology lead apron, are usually used to protect patients and radiology staff against ionizing radiation. Lead apron is a desirable shield due to high absorption and effective attenuation of x-ray photons in the diagnostic radiology range. OBJECTIVE Although lead aprons have good radiation protection properties, in recent years, researchers have been looking for alte...

Since the advent of catheter-based coronary intervention three decades ago, steady technological progress has led to the development and refinement of intracoronary devices [1]. Despite technological advances, the fundamental workflow of coronary procedures remains unchanged. Interventionalists still wear heavy protective lead aprons, stand at the bedside for long hours and manually manipulate ...
