In this article, electro-thermo nonlocal nonlinear vibration and instability of viscous-fluid-conveying double–walled boron nitride nanotubes (DWBNNTs) embedded on Pasternak foundation are investigated. The DWBNNT is simulated as a Timoshenko beam (TB) which includes rotary inertia and transverse shear deformation in the formulation. Considering electro-mechanical coupling, the nonlinear govern...

this study was conducted to quantify germination response of annual savory (satureja hortensis l.) to temperature and water potential. for this purpose, seeds were exposed to different temperature (12, 15, 20, 25, 30, 35, 37 and 40°c) and water potential (zero, -0.1, -0.3, -0.5 and -0.7 mpa) treatments in seed research lab., gorgan university of agricultural sciences and natural resources in 20...

A random matrix approach to glassy physics is introduced. It leads to a class of models that exhibit both glassy low-temperature phases and doubleand single-well configurations in their potential energy. The distribution of parameters characterizing the local potential energy configurations can be computed, and differ from those assumed in the standard tunneling model and its variants. Still, l...

We introduce a novel approach to the study of the folding of proteins whose native structures are already known. We use an off-lattice atomistic potential energy. The parameters of the potential energy are simultaneously optimized for several proteins. The low-lying local-energy minima for these proteins are found by conformational space annealing. The parameters are modified in such a way that...

Introduction Application of near-infrared absorbing nanostructures can induce hyperthermia, in addition to providing more efficient  photothermal effects. Gold-gold sulfide (GGS) is considered as one of these nanostructures. This study was performed on a tissue-equivalent optical-thermal phantom to determine the temperature profile in the presence and absence of GGS and millisecond pulses of a ...

Abstract This work investigated the electrochemical and aqueous tribological behavior of hot pressed 2205 duplex stainless steel (DSS). DSS sintered composites of different volume percent (% vol) of partially stabilized zirconia (PSZ) was developed using powder metallurgy (PM) technique. Electrochemical behaviour was studied at room temperature, using open circuit potential and potentiody...
