Does Formalization Facilitate Environmental Improvements in the Artisanal and Small‐Scale Mining Sector?

Business Strategy and the Environment, EarlyView.
ABSTRACT This paper explores the link between formalization and environmental performance in the artisanal and small‐scale mining (ASM) sector, focusing on the case of sub‐Saharan Africa. The impression often conveyed by experts is that a commitment to formalizing ASM—that is, moves made to bring the sector's operations into the legal domain, where ...

Effect of exogenous selenium supply on photosynthesis, Na+ accumulation and antioxidative capacity of maize (Zea mays L.) under salinity stress

Scientific Reports, 2017
The mechanism of selenium-mediated salt tolerance has not been fully clarified. This study investigated the possible role of selenium (Se) in regulating maize salt tolerance. A pot experiment was conducted to investigate the role of Se (0, 1, 5 and 25 μM

The Effect of Exogenously Applied Dicarboxylic Acids (Photon) on the Maize (Zea mays) Metabolite Profile

Chemistry &Biodiversity, EarlyView.
ABSTRACT Maize is an important crop worldwide with approximately 1200 million tons consumed and a market size worth $143 billion. Environmental stress influence production of crops and mitigating these ensures optimum production. Dicarboxylic acids are known as emulsifying agents that mitigate various stresses in plants.

Transcriptome-Wide Association Supplements Genome-Wide Association in Zea mays

G3: Genes, Genomes, Genetics, 2018
Modern improvement of complex traits in agricultural species relies on successful associations of heritable molecular variation with observable phenotypes. Historically, this pursuit has primarily been based on easily measurable genetic markers.

Synthesis and Characterization of Dummy Template‐Based Molecularly Imprinted Polymers for Extraction of Aflatoxins in Food Samples

Chemistry &Biodiversity, EarlyView.
Five dummy templates and two functional monomers were systematically evaluated for the preparation of selective MIPs for aflatoxins. 5,7‐Dimethoxycoumarin and methacrylic acid were found to produce highly selective MIPs, and the adsorbent was characterized by FTIR, TGA, and SEM.
