In silico comparative analysis of conserved genes expressed in solanaceous plants under abiotic stresses [PDF]

open access: yes, 2011
The gene expression data was studied in order to analyze genes involved in different abiotic stresses in solanaceous plants. Salt, temperature (heat & cold) and drought are the main abiotic stresses to the plants.

Advanced Mapping of Optically-Blind and Optically-Active Nitrogen Chemical Impurities in Natural Diamonds

open access: yesChemosensors, 2022
Natural diamonds with a rich variety of optically blind and optically active nitrogen impurity centers were explored at a nano/microscale on the surface and in bulk by a number of advanced chemical and structural analytical tools in order to achieve a ...

Casimir stresses in active nematic films

open access: yes, 2019
We calculate the Casimir stresses in a thin layer of active fluid with nematic order. By using a stochastic hydrodynamic approach for an active fluid layer of finite thickness $L$, we generalize the Casimir stress for nematic liquid crystals in thermal ...

Interplay of internal stresses, electric stresses and surface diffusion in polymer films

open access: yes, 2011
We investigate two destabilization mechanisms for elastic polymer films and put them into a general framework: first, instabilities due to in-plane stress and second due to an externally applied electric field normal to the film's free surface.

Quasistaticity of the process of dynamic strain of soils

open access: yesИнженерно-строительный журнал, 2019
Mechanical characteristics of soil under static and dynamic strains are determined experimentally. Their accuracy and reliability depends on quasi-static nature of strain process in soil.

Contributions to the Dynamic Regime Behavior of a Bionic Leg Prosthesis

open access: yesBiomimetics, 2023
The purpose of prosthetic devices is to reproduce the angular-torque profile of a healthy human during locomotion. A lightweight and energy-efficient joint is capable of decreasing the peak actuator power and/or power consumption per gait cycle, while ...

Stresses in curved nematic membranes

open access: yes, 2018
Ordering configurations of a director field on a curved membrane induce stress. In this work, we present a theoretical framework to calculate the stress tensor and the torque as a consequence of the nematic ordering; we use the variational principle and ...
