Numerical and analytical modeling of annular flow reveals the hydraulic performance of sustainable drilling muds formulated from Congolese kaolinitic clay, okra mucilage, and plant ashes. Yield stress enhances cuttings transport, while shear‐thinning behavior reduces pressure losses and pumping energy.

ABSTRACT Background Hydrogen sulfide (H2S) is an endogenous gasotransmitter regulating redox balance, inflammation, and vascular tone, but reproducing the spatial and kinetic features of endogenous production remains challenging. We examine sulfurous thermal waters as natural contexts of sustained H2S exposure, using the Saturnia springs (Tuscany ...

This review highlights the utilisation of textile waste in fibre‐reinforced polymer composites to reduce environmental impacts of pre‐ and post‐consumer textile waste. It critically examines waste composites’ manufacturing processes, their structural details, mechanical, thermal, physical properties, while discussing chemical treatments, hybridization ...

ABSTRACT Soilless cultivation has emerged as an effective approach for improving cucumber productivity under protected cultivation by enhancing root‐zone conditions and minimizing soil‐borne constraints. However, the performance of different growing media combinations remains insufficiently understood.

Methods for assessing problem‐solving competencies in preschoolers: A scoping review
Abstract Problem‐solving is an important 21st‐century skill and an indispensable part of early STEM (science, technology, engineering and mathematics) education. To effectively study the development of children's problem‐solving competencies and to evaluate the effectiveness of classroom interventions and programmes, researchers and educators need ...

Vertical Hydraulic Gradients as Key Calibration Constraints in Regional Groundwater Models
Abstract In typical clastic sedimentary aquifer systems, interbedded coarse‐ and fine‐grained deposits impede vertical flow and promote horizontal flow. This effect, known as vertical anisotropy, is often underestimated in regional groundwater models, leading to overestimated vertical aquifer communication.

Riparian forest buffers support biodiversity, ecosystem functioning and food webs in human‐modified landscapes, and dampen land‐use and climate stressors (sediments, nutrients, thermal maxima), motivating their wider use in management. These outcomes were regulated by the presence or size of mostly small, mature buffers and sometimes by proximity among
