J. Rezaeifar; A. Rohani; M. A. Ebrahimi-Nik

Volume 14, Issue 1 , March 2024, Pages 15-34

https://doi.org/10.22067/jam.2023.83173.1176

Abstract
  In the quest for enhanced anaerobic digestion (AD) performance and stability, iron-based additives as micro-nutrients and drinking water treatment sludge (DWTS) emerge as key players. This study investigates the kinetics of methane production during AD of dairy manure, incorporating varying concentrations ...  Read More

D. Baveli Bahmaei; Y. Ajabshirchy; Sh. Abdollahpour; S. Abdanan Mehdizadeh

Volume 14, Issue 1 , March 2024, Pages 35-47

https://doi.org/10.22067/jam.2023.83626.1182

Abstract
  This research aims to optimize the mixing process in gas-lift anaerobic digesters of municipal sewage sludge since mixing and maintaining uniform contact between methanogenic bacteria and nutrients is essential. Wastewater municipal sludge sampling was performed at the Ahvaz West treatment plant (Chonibeh, ...  Read More

A Finite Element Model of Soil-Stress Probe Interaction under a Moving Rigid Wheel

M. Naderi-Boldaji; H. Azimi-Nejadian; M. Bahrami

Volume 14, Issue 1 , March 2024, Pages 49-67

https://doi.org/10.22067/jam.2023.84158.1185

Abstract
  Machinery traffic is associated with the application of stress onto the soil surface and is the main reason for agricultural soil compaction. Currently, probes are used for studying the stress propagation in soil and measuring soil stress. However, because of the physical presence of a probe, the measured ...  Read More

Modeling Soil Pressure-Sinkage Characteristic as Affected by Sinkage rate using Deep Learning Optimized by Grey Wolf Algorithm

B. Golanbari; A. Mardani; A. Hosainpour; H. Taghavifar

Volume 14, Issue 1 , March 2024, Pages 69-82

https://doi.org/10.22067/jam.2023.84339.1188

Abstract
  Due to the numerous variables that may influence the soil-machine interaction systems, predicting the mechanical response of soil interacting with off-road traction equipment is challenging. In this study, deep neural networks (DNNs) are chosen as a potential solution for explaining the varying soil ...  Read More

Cold Plasma Technique in Controlling Contamination and Improving the Physiological Processes of Cereal Grains (a Review)

M. Pourbagher; R. Pourbagher; M. H. Abbaspour-Fard

Volume 14, Issue 1 , March 2024, Pages 83-104

https://doi.org/10.22067/jam.2023.84647.1193

Abstract
  Today, almost half of the total human food, especially in Asia, is directly supplied from grains, and nearly 70% of the cultivated area of the world, which is one billion hectares, is used for growing grains. Therefore, non-destructive methods must be found and developed to increase seed quality in agriculture ...  Read More
