On‐farm experimentation in East and West Africa improves nutrient management decision‐making and yield in cereal smallholder farming systems

Agronomy Journal, Volume 118, Issue 1, January/February 2026.
Abstract Past efforts have concentrated on top‐down approaches in delivering precision nutrient management (PNM) practices to smallholder farmers, but with little yield and economic impact for farmers. Farmer‐centric on‐farm experimentation (OFE) is an approach designed to effectively engage farmers in generating technologies tailored to the ...

Impact of Yamoussoukro lakes water on lettuce quality

Journal of Applied Sciences and Environmental Management, 2006
Waters from lakes, in Yamoussoukro city (Cote d'Ivoire), are usually used for legumes irrigation. However, these lakes were found to be polluted in previous works, inducing probably legume toxicity. The purpose of this work is to draw the relationship between water quality and legume (lettuce) one via their respective physical and chemical ...

New Detector Sensitivity Calibration and the Calculation of the Interaction Force between Particles Using an Optical Tweezer

Micromachines, 2018
We propose a new approach to calculate the sensitivity factor of the detector in optical tweezers. In this work, we used a charge-coupled device (CCD) camera and a quadrant photodiode (QPD) for the extraction of the various positions occupied by the ...

Making green cocoa: Deforestation, the legacy of war, and agrarian capitalism in Côte d'Ivoire

Journal of Agrarian Change, Volume 25, Issue 1, January 2025.
Abstract This article examines the legacy of war on environmental policy, contributing to recent literature on the linkages between armed violence, conservation, rural livelihoods and global value chains. It argues that environmental norms reshape agricultural practices, but also the means by which people claim control over land and labour.

Analysis of the Weak Formulation of a Coupled Nonlinear Parabolic System Modeling a Heat Exchanger

Abstract and Applied Analysis, Volume 2025, Issue 1, 2025.
This paper establishes the existence, uniqueness and time–space regularity of the weak solution to a nonlinear coupled parabolic system modeling temperature evolution in a coaxial heat exchanger with source terms and spatially varying coefficients. The system is formulated in a weak sense and the analysis relies on a Faedo–Galerkin method tailored to ...
