in this paper, thermo-elastic analysis of a rotating thick truncated conical shell subjected to the temperature gradient, internal pressure and external pressure is presented. given the existence of shear stress in the conical shell due to thickness change along the axial direction, the governing equations are obtained based on first-order shear deformation theory (fsdt). these equations are so...
chemical flooding, especially alkaline/surfactant/polymer flooding, is of increasing interest due to the world increasing oil demand. this work shows the aspects of using alkaline/surfactant/polymer as an enhanced oil recovery method in the porous media having a high dead-end pore frequency with various dead-end pore parameters (such as opening, depth, aspect ratio, and orientation). using glas...
This experiment was carried out to study the effects of different levels of vitamin C (0, 150, 300 and 450 ppm) and cage density (3, 4 and 5 birds) on performance and egg shell quality of laying hens under high environmental temperature. In a completely randomized design with 3 × 4 factorial arrangement, one hundred and ninety two (192) 25 week white leghorn hens were divided into 48 replicates...
In the framework of spherical geometry for jellium and local spin density approximation, we have obtained the equilibrium rs values, r̄s(N, ζ), of neutral and singly ionized “generic” N -electron clusters for their various spin polarizations, ζ. Our results reveal that r̄s(N, ζ) as a function of ζ behaves differently depending on whether N corresponds to a closed-shell or an openshell cluster. Th...
objectives: almond (prunus amygdalus) hull and shell are agricultural by-products that are a source of phenolic compounds.the processing of almond produce shell and hull, accounts for more than 50% by dry weight of the almond fruits. recently, more studies have focused on the influence of storage conditions and postharvest handling on the nutritional quality of fruits, especially the antioxidan...
The overall goal of this study was to fabricate multifunctional core-shell microcapsules with biological cells encapsulated within the polymer shell. Biocompatible temperature responsive microcapsules comprised of silicone oil droplets (multicores) and yeast cells embedded in a polymer matrix (shell) were prepared using a novel microarray approach. The cross-linked polymer shell and silicone mu...
In the present study, vibration of cylindrical laminates with different layers and angles were studied. In order to actuate and polarize in radial direction, a piezoelectric layer was located at outer surface of composite shell. Laminates were assumed long enough so that plane strain state analysis in 2D can be used properly. In order to satisfy the boundary conditions, variables in terms of Fo...
In this paper, slow light in a composite consisting of core-shell nanoparticles doped in a dielectric is studied. The light-velocity slowing factor as a function of the incident light frequency is discussed and analyzed. The influence of the thickness of shell, the composition of core and shell and the geometrical shape of nanoparticles on the slowing factor is investigated. The effect of the p...
This study was conducted to estimate the genetic parameters influencing egg quality in Khorasan Razavi native fowl. (Co)Variance components were estimated by the Bayesian statistical method via Gibbs sampling in GIBBS3F90 software. 1000 eggs (28-29 weeks old) were collected from 775 hens of the ninth generation of Khorasan-Razavi Province native fowl breeding center. External (egg weight,specif...
