A Decade of Change and Future Prospects of Organic Farming in Iran Using the Multi‐Round Delphi Method

open access: yesFUTURES &FORESIGHT SCIENCE, Volume 7, Issue 3, December 2025.
ABSTRACT In recent years, the concept of organic farming has gained increasing attention due to its reduced use of agrochemicals, ecological preservation, and contribution to sustainability. However, the analysis of data from 2013 to 2021 shows that organic agriculture in Iran remained almost unchanged until 2016, with approximately 18,871 hectares ...

On the symmetry of steady periodic water waves with stagnation points

open access: yesCommunications on Pure and Applied Analysis, 2012
The aim of this paper is to prove the symmetry of small-amplitude steady periodic water waves with monotonic wave profile even if stagnation points occur in the flow beneath the wave.

Periodic Steady Vortices in a Stagnation Point Flow II

open access: yes
Steady-state perturbations to a stagnation point flow of the form ${\bf U}=(0,A'y,-A'z)$ are known which consist of a periodic array of counter-rotating vortices whose axes are parallel to the $y$-axis and which lie in the plane $z=0$. A new understanding of how these vortices depend on the supply of incoming vorticity from afar has lead to the ...
