A Perennial Green Revolution to address 21st‐century food insecurity and malnutrition

Food and Energy Security, Volume 13, Issue 4, July/August 2024.
Abstract Farming practices of the past century have dramatically increased annual crop yields to unprecedented levels but have consequentially created increasing ecological and public health concerns, posing a long‐term threat to global food security. Soil tillage and chemical inputs perpetuate soil erosion, biodiversity loss, wetlands eutrophication ...

Mapping nut‐cracking in a new population of wild capuchin monkeys (Sapajus libidinosus) at Ubajara National Park, Brazil

American Journal of Primatology, Volume 86, Issue 4, April 2024.
Capuchin monkeys (Sapajus libidinosus) at Ubajara National Park, Brazil, customarily use hammerstones to crack open at least two species of palm nuts, macaúba and babaçu. We systematically surveyed stone tool use sites in this park, recording and measuring stone tools, processed foods, and available lithic resources.

Using Gibbs Energy Additivity Methods for QSPR to Model the Density of Fatty Acid Ethyl Esters and Biodiesels

Journal of Chemistry, Volume 2024, Issue 1, 2024.
Liquid fuel density is an essential physical parameter in the design and application processes. This paper employed the Gibbs free energy technique with quantitative structure‐property relationship (QSPR) for determining the density of pure fatty acid ethyl ester (FAEE) and ethyl ester biodiesel at temperature 283.15–363.15 K.
