Exergoenvironmental damages assessment in a desert‐based agricultural system: A case study of date production

open access: yesAgronomy Journal, Volume 114, Issue 6, Page 3155-3172, November/December 2022., 2022
Abstract Developing countries, especially those in hot and dry areas, need more attention to achieve sustainable development as they apply excessive inputs in production processes. The present study aims to quantify the amount of environmental emissions and determine the most appropriate pattern of energy use in the date (Phoenix dactylifera L ...

Maize–soybean intercropping: A bibliometric analysis of 30 years of research publications

open access: yesAgronomy Journal, Volume 114, Issue 6, Page 3377-3388, November/December 2022., 2022
Abstract Maize (Zea may L.)–soybean [Glycine max (L.) Merr.] intercropping is popular in many countries because of its high productivity. However, no studies have explored maize–soybean intercropping via bibliometric methods. Taking the Web of Science database, the visualization applications of CiteSpace and VOSviewer were used to visually analyze the ...

Phylogeny and expression analyses reveal important roles for plant PKS III family during the conquest of land by plants and angiosperm diversification

open access: yesFrontiers in Plant Science, 2016
Polyketide synthases (PKSs) utilize the products of primary metabolism to synthesize a wide array of secondary metabolites in both prokaryotic and eukaryotic organisms. PKSs can be grouped into three distinct classes, type I, II, and III, based on enzyme

Gapped vegetation patterns: crown/root allometry and snaking bifurcation [PDF]

open access: yes, 2019
Nonuniform spatial distributions of vegetation in scarce environments consist of either gaps, bands often called tiger bush or patches that can be either self-organized or spatially localized in space. When the level of aridity is increased, the uniform vegetation cover develops localized regions of lower biomass.

A Review of Vegetation Encroachment Detection in Power Transmission Lines using Optical Sensing Satellite Imagery [PDF]

open access: yes, 2020
Vegetation encroachment in power transmission lines can cause outages, which may result in severe impact on economic of power utilities companies as well as the consumer. Vegetation detection and monitoring along the power line corridor right-of-way (ROW) are implemented to protect power transmission lines from vegetation penetration.
