Selected Indices to Identify Water-Stress-Tolerant Tropical Forage Grasses

open access: yesPlants, 2022
Periods of soil water stress have been recurrent in the Cerrado region and have become a growing concern for Brazilian tropical pasture areas. Thus, the search for forage grasses more tolerant to water stress has intensified recently in order to promote ...

The present-day stress field in Egypt

open access: yesAnnals of Geophysics, 2001
The present-day stress field has been investigated by the analysis of the directions of maximum horizontal stress (ó 1 ) inferred from earthquake focal mechanisms and borehole breakouts in Egypt.

Numerical modeling of in-situ stress and prediction of favorable area of shale gas layer in Wufeng to Longmaxi formations, Nanchuan region, southeastern Chongqing

open access: yesShiyou shiyan dizhi, 2023
Upper Ordovician Wufeng to Lower Silurian Longmaxi formations in Nanchuan region, as an important shale gas productive layer, is characterized by large shale thickness, deep burial depth, and complex in-situ stress with rapid direction changes. Therefore,

A rate- and state-dependent ductile flow law of polycrystalline halite under large shear strain and implications for transition to brittle deformation [PDF]

open access: yes, 2010
We have conducted double-shear biaxial deformation experiments in layers of NaCl within its fully-plastic (FP) regime up to large shear strains (γ < 50) with velocity steps.

NW Australian intraplate seismicity and stress regime [PDF]

open access: yesJournal of Geophysical Research: Solid Earth, 2009
The interrelations between stress orientation, regional deformation, and seismic activity in the context of intraplate seismicity continue to pose difficult questions. Stress models of the Australian continent are largely based on nonseismic information.

Polymer stress growth in viscoelastic fluids in oscillating extensional flows with applications to micro-organism locomotion [PDF]

open access: yes, 2019
Simulations of undulatory swimming in viscoelastic fluids with large amplitude gaits show concentration of polymer elastic stress at the tips of the swimmers.We use a series of related theoretical investigations to probe the origin of these concentrated ...

Multifractal analysis of stress time series during ultrathin lubricant film melting [PDF]

open access: yes, 2010
Melting of an ultrathin lubricant film confined between two atomically flat surfaces is we studied using the rheological model for viscoelastic matter approximation. Phase diagram with domains, corresponding to sliding, dry, and two types of $stick-slip$

Crossover from quasi-static to dense flow regime in compressed frictional granular media [PDF]

open access: yes, 2013
We investigate the evolution of multi-scale mechanical properties towards the macroscopic mechanical instability in frictional granular media under multiaxial compressive loading.

Bi-directional extensional control of the Berane Basin formation, northern Montenegro [PDF]

open access: yesGeološki Anali Balkanskoga Poluostrva
The Berane Basin is a Miocene, northeast‐southwest oriented intramountain basin of the Dinarides, overlying the pre‐neotectonic basement of the Drina–Ivanjica unit, the East Bosnian–Durmitor unit and the Western Vardar Zone.

Actively stressed marginal networks [PDF]

open access: yes, 2012
We study the effects of motor-generated stresses in disordered three dimensional fiber networks using a combination of a mean-field, effective medium theory, scaling analysis and a computational model.
