Changes in Photo-Protective Energy Dissipation of Photosystem II in Response to Beneficial Bacteria Consortium in Durum Wheat under Drought and Salinity Stresses

open access: yesApplied Sciences, 2020
The present research aimed at evaluating the harmless dissipation of excess excitation energy by durum wheat (Triticum durum Desf.) leaves in response to the application of a bacterial consortium consisting of four plant growth-promoting bacteria (PGPB).

Physiological response to low-nitrogen stress and comprehensive evaluation in four rice varieties

open access: yesPhotosynthetica
Rice (Oryza sativa L.) research has rarely focused on the response to low-nitrogen stress in different subtypes previously and lacked a low-nitrogen tolerance evaluation system.

Energy-consistent discretization of viscous dissipation with application to natural convection flow [PDF]

open access: yesComputers & Fluids, 2023
A new energy-consistent discretization of the viscous dissipation function in incompressible flows is proposed. It is implied by choosing a discretization of the diffusive terms and a discretization of the local kinetic energy equation and by requiring ...

Analysis of Stress in the Cohesive Zone, Dissipation and Fracture Energy During Shear Rupture Experiments [PDF]

open access: yesGeophysical Research Letters
We analyze high resolution slip rate data obtained during dynamic shear rupture experiments by Berman et al. (2020), https://doi.org/10.1103/physrevlett.125.125503. We use an inverse method to extract the details of strength evolution within the cohesive

ALLDMD Dissipation Energy Analysis by the Method Extended Finite Elements of a 2D Cracked Structure of an Elastic Linear Isotropic Homogeneous Material

open access: yesJournal of Electronics,Computer Networking and Applied Mathematics, 2023
The analysis of the crack parameters of a material is an important effect for characterizing the state of stress. Nowadays, materials occupy a very necessary place in modern industry for the study of the life of such structure.

Relationship between acoustic emission and energy dissipation: a DEM study of soil–structure interaction

open access: yesActa Geotechnica, 2022
Acoustic emission (AE) monitoring offers the potential to sense particle-scale interactions that lead to macro-scale responses of granular materials; however, there remains a paucity of understanding of the fundamental links between particle-scale ...

Dissipation scaling and structural order in turbulent channel flows [PDF]

open access: yesThe Physics of Fluids, 2021
Scaling and structural evolutions are contemplated in a new perspective for turbulent channel flows. The total integrated turbulence kinetic energy remains constant when normalized by the friction velocity squared, while the total dissipation increases ...

Effect of Drought Stress on Chlorophyll Fluorescence Parameters, Phytochemical Contents, and Antioxidant Activities in Lettuce Seedlings

open access: yesHorticulturae, 2021
This study monitored changes in chlorophyll fluorescence (CF), growth parameters, soil moisture content, phytochemical content (proline, ascorbic acid, chlorophyll, total phenol content (TPC), and total flavonoid content (TFC)), and antioxidant ...

A New Index of Energy Dissipation Considering Time Factor under the Impact Loads

open access: yesMaterials, 2022
Rock failure phenomena are accompanied by abundant energy variation, and the energy dissipation can explain the dynamic mechanical characteristics of the rock. In this study, a series of granite specimens (a total of 60) with different aspect ratios were

Coupled models for total stress dissipation tests

open access: yes, 2021
Two linear, point-symmetric, coupled consolidation model families with various embedding space dimension values (oedometer models - 1, spherical models - 3, cylindrical models - 2), differing in one boundary condition (coupled 1 - constant displacement, coupled 2 - constant stress) are analysed analytically and numerically.
