Obstetrics and gynecology devices designed for low‐ and middle‐income countries: A narrative review

International Journal of Gynecology &Obstetrics, Volume 169, Issue 1, Page 71-80, April 2025.
Abstract There are many barriers contributing to poor health outcomes for women in low‐ and middle‐income countries (LMICs), one of which is the lack of necessary medical devices. Presently, the development of various kinds of devices intended to improve women's health outcomes specifically in LMICs remains underrepresented in the literature; therefore,

Study of the time-dependent clear water scour around circular bridge piers

Journal of Hydrology and Hydromechanics, 2017
The local scour around bridge piers influences their stabilities and plays a key role in the bridge failures. The estimation of the maximum possible scour depth around bridge piers is an important step in the design of the bridge pier foundations.

Backwater controls of avulsion location on deltas [PDF]

, 2012
River delta complexes are built in part through repeated river-channel avulsions, which often occur about a persistent spatial node creating delta lobes that form a fan-like morphology. Predicting the location of avulsions is poorly understood, but it is

The anatomy of exhumed river-channel belts: Bedform to belt‐scale river kinematics of the Ruby Ranch Member, Cretaceous Cedar Mountain Formation, Utah, USA [PDF]

, 2020
Many published interpretations of ancient fluvial systems have relied on observations of extensive outcrops of thick successions. This paper, in contrast, demonstrates that a regional understanding of palaeoriver kinematics, depositional setting and ...
