The snub-nosed, reclining, and serene image of the fetus is commonplace in cultural representations and analyses of obstetric ultrasound. Yet following the provocation of various feminist scholars, taking the fetal sonogram as the automatic object of concern vis-à-vis ultrasound cedes ground to anti-abortionists, who deploy fetal images to argue that life begins at conception and that the unborn are rights bearing subjects who must be protected. How might feminists escape this analytical trap, where discussions of ultrasonics must always be engaged in the act of debunking? This article orients away from the problem of fetal representation by employing a method which may appear to be wildly unsuitable: media archaeology.

The choroid, which is a highly vascularized layer between the retina and sclera, is essential for supplying oxygen and nutrients to the outer retina. Choroidal vascular dysfunction has been implicated in numerous ocular diseases, including age-related macular degeneration, central serous chorioretinopathy, polypoidal choroidal vasculopathy, and myopia. Traditionally, the in vivo assessment of choroidal blood flow relies on techniques such as laser Doppler flowmetry, laser speckle flowgraphy, pneumotonometry, laser interferometry, and ultrasonic color Doppler imaging.

is a mega-diverse genus of pioneer plants that contributes to the maintenance and regeneration of tropical forests. In the Neotropics, bats use olfaction to forage for fruit and are a main disperser of seeds via consumption and subsequent defecation during flight. In return, fruits provide essential nutrients for year-round.

Purpose: Graphene-polymer nanocomposites significantly impact dental filler and antibacterial applications. The study aims to overcome some problems dental filers present and improve their properties and antibacterial activity. Synthesis graphene oxide (GO) and poly (methyl methacrylate) (PMMA) were used to reinforce two types of commercial hybrid/nano-dental fillings.
