in the current investigation a novel nano hybrid adsorbent mcm-41/n-(3-trimethoxysilyl)-propyl)diethylenetriamine (mcm-41/tmspdeta) was prepared and was characterized using dls (dynamic light scattering), fourier transform infrared (ftir), x-ray diffraction (xrd), brunauer–emmett–teller (bet) analytical techniques and transmission electron microscopy (tem). the synthesized mcm-41/tmspdeta adsor...

In this work, we numerically consider a thermoelastic problem where the thermal law is modeled using so-called Moore–Gibson–Thompson equation. This thermomechanical written as coupled system composed of hyperbolic partial differential equation for transformation displacement field and parabolic temperature. Its variational formulation in terms derivatives above transformed functions, leading to...

Some technical aspects of Cluster Perturbation Theory (CPT) are presented. CPT is an approximation scheme for calculating the oneparticle Green function of the Hubbard model of interacting electrons on a lattice. It proceeds by (i) dividing the lattice into identical clusters and calculating the Green function by exact diagonalization on a given cluster (ii) extending this Green function to the...

Abstract In the past few decades, many models have been proposed to address shortcomings found in classical theories of thermoelasticity and allow limited speeds heat waves. this context, current paper a new generalized model based on Moore–Gibson–Thompson (MGT) equation has introduced. This can be derived by introducing relaxation time factor into third type Green–Naghdi (GN-III). contrast pre...

Javamide-I/javamide-II are phenolic amides found in coffee. Recent reports suggested that they may contain several biological activities related to human health. Therefore, there is emergent interest about their quantities in coffee-related products. Green coffee extract is a powder extract made of unroasted green coffee beans, available as a dietary supplement. However, there is little informa...

Background: Visfatin is protein with insulin-like function that is expressed in high levels in visceral fat tissue and its circulating levels is associated with obesity and diabetes. Objective: The purpose of this study was to examine the effect of 10 weeks of rhythmic aerobic exercise and green tea supplementation on visfatin levels and insulin resistance in obese type II diabetic women. Met...

This paper derives an averaged Lagrangian functional for dynamic coupling between rigid-body motion and its interior shallow-water sloshing in three-dimensional rotating translating coordinates; with a time-dependent rotation vector. A new set of variational equations (SWEs) generalized Green–Naghdi the fluid 3-D vector translations, also linear momentum angular containing shallow water, are de...

In the present research, vibrational behavior of anisotropic protein microtubules (MTs) immersed in cytosol via Cooper–Naghdi shell model is investigated. MTs are hollow cylindrical structures in the eukaryotic cytoskeleton which surrounded by filament network. The temperature effect on vibration frequency is also taken into account by assuming temperature-dependent material properties for MTs....

This study is concerned with the generation and propagation of strongly nonlinear waves in shallow water. A numerical wave flume developed where solitary cnoidal types are generated by use Level I Green-Naghdi (GN) equations a piston-type wavemaker. Waves GN theory enter domain fluid motion governed Navier–Stokes to achieve highest accuracy for propagation. The computations performed two dimens...
