The Critical Role of Economies of Scale: A Techno‐Economic Assessment of Small‐ Versus Large‐Scale Biogas Upgrading in Rural Tanzania

open access: yesEnergy Science &Engineering, EarlyView.
Small‐scale biogas upgrading can improve methane quality but remains financially unattractive to individual rural households. Community‐scale implementation substantially lowers energy costs, demonstrating that economies of scale are critical to making purified biogas a viable clean‐cooking option in Tanzania.

Experimental Characterization of the Effects of Mineral‐Based Fire‐Retardant Admixtures on the Combustion Properties of Polyethylene Blends

open access: yesFire and Materials, EarlyView.
ABSTRACT The growing demand for flame retardant (FR) polymeric materials has highlighted the need to improve the combustion behaviour of highly flammable polymers such as polyethylene (PE). This study investigates the use of eco‐sustainable mineral FRs as a strategy to reduce heat release and smoke production during combustion, while improving the ...

Bryozoan‐Rich Carbonate Units of the Erfoud Area (SE Morocco) Record Latest Katian to Early Hirnantian Interglacial Intervals

open access: yesGeological Journal, EarlyView.
In this study, we re‐examine the depositional architecture of the Erfoud limestone in Morocco. Introducing new biostratigraphic constraints from chitinozoan assemblages, we show that Katian to Hirnantian bryozoan‐pelmatozoan meadows reflect flooding events linked to a series of interglacial transgressions known to have occurred immediately prior to the

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

open access: yesInternational 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,

The Effect of Geotextile Layer in Decreasing Local Scour of Cylindrical Bridge Pier

open access: yesعلوم آب و خاک, 2017
Flood currents are considered threatening factors by creating local scour along bridge piers. One method for decreasing local scour is to strengthen the bed against imposed tensions.
