Effect of drought stress and maternal growth conditions on germination and seedling growth of wild oat (Avena ludoviciana) [PDF]

open access: yesعلوم و فناوری بذر ایران, 2017
Because of the importance of the role of maternal environment during seed development on germination of produced seed and seedling establishment an experiment in a randomized complete block design base as a factorial was conducted to evaluate effects of ...

Spatiotemporal variations in the stress field in the northeasternmost part of the NE Japan arc: constraints from microearthquakes

open access: yesEarth, Planets and Space, 2020
We determined focal mechanism solutions of microearthquakes and examined the stress field in the low-seismicity region from southern Hokkaido to eastern Aomori, NE Japan.

Single asperity friction in the wear regime

open access: yesFriction, 2018
We used molecular dynamics simulation to investigate the friction of a single asperity against a rigid substrate, while generating debris. In the low wear regime (i.e., non-linear wear rate dependence on the contact stress, via atom-by-atom attrition ...

Understanding of the Retarded Oxidation Effects in Silicon Nanostructures [PDF]

open access: yes, 2012
In-depth understanding of the retarded oxidation phenomenon observed during the oxidation of silicon nanostructures is proposed. The wet thermal oxidation of various silicon nanostructures such as nanobeams, concave/convex nanorings and nanowires ...

Stress Regimes and Stress Fields Analysis Using Fault-Slip Data; Eastern Iran

open access: yesGlobal Journal of Earth Science and Engineering, 2023
In this paper direction of stress tensors and stress ellipsoids shape in Neogene, Paleogene, and older units were investigated. Moreover, relationship between shape of stress ellipsoid and exhumation of igneous units were determined using analysis of stress tensors.

Change of stress regime during geothermal reservoir stimulation [PDF]

open access: yesGeophysical Research Letters, 2014
Earthquakes are induced by man‐made changes of the stress field by injection or withdrawal of fluids in hydrocarbon production, geothermal exploitation, and wastewater disposal. However, the actual perturbation of the stress field and stress release by injection‐induced seismicity remains largely unknown.
