Rice growth monitoring is very important as rice is one of the staple crops of the world. Rice variables as quantitative indicators of rice growth are critical for farming management and yield estimation, and synthetic aperture radar (SAR) has great advantages for monitoring rice variables due to its all-weather observation capability. In this study, eight temporal RADARSAT-2 full-polarimetric ...
The present paper reports on the use of Modified Wöhler Curve Method (MWCM) applied along with nominal stresses to estimate lifetime notched additively manufactured metallic materials subjected constant and variable amplitude multiaxial fatigue loading. MWCM is by defining critical plane via direction that experiences maximum variance resolved shear stress. In this setting, owing fact stress a ...
This paper presents a simple and systematic way for imposing boundary conditions in the differential quadrature free and forced vibration analysis of beams and rectangular plates. First, the Dirichlet- and Neumann-type boundary conditions of the beam (or plate) are expressed as differential quadrature analog equations at the grid points on or near the boundaries. Then, similar to CBCGE (direct ...
To optimize the conversion efficiency of plastic dye-sensitized solar cells fabricated by the electrophoretic deposition technique, anatase TiO2 nanoparticles of various sizes from 10 nm to 27 nm have been synthesized via a simple hydrothermal process. The obtained TiO2 nanoparticles have been characterized by X-ray diffraction and high resolution transmission electron microscopy, which confirm...
plant cell cultures could be used as an important tool for biochemical production, ranging from natural pigments to pharmaceutical products. anthocyanin is affected by a variety of factors. light, an important plant environmental factor, influences the anthocyanin production in vegetative plant tissues. here, we have investigated the influence of the blue laser-diode (bld) and red laser-he ne (...
The direct formic acid fuel cell is an emerging energy conversion device for which palladium is considered as the state-of-the-art anode catalyst. In this communication, we show that the activity and stability of palladium for formic acid oxidation can be significantly enhanced using nickel phosphide (Ni(2)P) nanoparticles as a cocatalyst. X-ray photoelectron spectroscopy (XPS) reveals a strong...
• Uniaxial and multiaxial fatigue tests under proportional loading were conducted. Multiaxial high-cycle behaviour of S355 structural steel was obtained. Five different models used evaluated. The Dang Van’s multiscale approach Susmel model showed great accuracy. stresses are usually present in engineering structures often associated to failures. However, is an open topic, full questions points ...

Flowerlike CeO2 coated with Sr2Fe1.5Mo0.5Ox (Sr-Fe-Mo-oxide) nanoparticles exhibits enhanced conductivity at low temperatures (300-600 °C), e.g. 0.12 S cm(-1) at 600 °C, this is comparable to pure ceria (0.1 S cm(-1) at 800 °C). Advanced single layer fuel cell was constructed using the flowerlike CeO2/Sr-Fe-Mo-oxide layer attached to a Ni-foam layer coated with the conducting transition metal o...
The solid state dye sensitized solar cell is one of the most promising organic based device concepts which demonstrates solar power conversion efficiencies in excess of 4%. The basic strategy of this hybrid system is that light is absorbed in a dye to form an excited electronic state, termed an exciton. Electron transfer takes place from the excited dye molecule to an inorganic semiconductor, w...
