Analytic expressions were derived for the compressibility factor and residual internal energy of the square-well plus Sutherland fluid. In this derivation, we used the second order Barker-Henderson perturbation theory based on the macroscopic compressibility approximation together with an analytical expression for radial distribution function of the reference hard sphere fluid. These properties...

Congo red (CR) is a stable anionic diazo dye that causes allergic reactions with carcinogenic properties. The rapid removal of CR using cation-incorporated nanohydroxyapatite (pristine HAp: X (X = Fe, Ni, Zn, Co, and Ag)) was investigated. pristine cation ion-doped HAp adsorbents were coprecipitated subjected to hydrothermal ultrasound treatments subsequent microwave drying. dopant ions signifi...

Background: Renal osteodystrophy (ROD) is a common bone and mineral metabolism disorder in patients with end-stage renal disease (ESRD). This study aimed to determinate the frequency of the subtypes of ROD and evaluate the diagnostic value of biochemical as the well as radiographic markers for the diagnosis of ROD among hemodialysis patients in Golestan province of Iran.  Materials and Methods...

underlying visual processing in dim light is well conserved. Individual rod photoreceptors, themselves capable of reliably signaling the absorption of individual photons (6, 9), are pooled in a specialized circuitry referred to as the rod bipolar pathway (17, 49). Following a series of convergent connections in this pathway, the ganglion cells, which are the output cells of the retina, send sig...

Abstract: Phononic crystals can be used to control elastic waves due to their frequency bands. This paper analyzes the passive and active control as well as the dispersion properties of longitudinal waves in rod-type piezoelectric phononic crystals over large frequency ranges. Based on the Love rod theory for modeling the longitudinal wave motions in the constituent rods and the method of rever...

Cobalt ferrite (CoFe2O4) nanorods were synthesized by iron chloride (FeCl3.6H2O) and cobalt sulfate hexahydrate (CoSO4.7H2O) as precursor in the presence of ethylene glycol agent and poly vinyl pyrrolidone (PVP) surfactant. The samples were characterized to identify the physical properties. XRD pattern of cobalt ...

This article is concerned with the theoretical analysis of the functionally graded magneto-electro-thermoelastic hollow sphere due to uniform surface heating. We analyze the transient thermoelastic problem for a functionally graded hollow sphere constructed of the spherical isotropic and linear magneto-electro-thermoelastic materials using a laminated composite mode as one of theoretical approx...

Calcium carbonate, especially with nanostructure, has been considered as a good candidate material for bone regeneration due to its excellent biodegradability and osteoconductivity. In this study, rod-like calcium carbonate nanoparticles (Rod-CC NPs) with desired water dispersibility were achieved with the regulation of poly (acrylic acid). Characterization results revealed that the Rod-CC NPs ...

Lead and mercury have been reported to alter selectively the rod component of the electroretinogram, and to inhibit the phosphodiesterase in rod outer segments which may be responsible for generating the rods' light response. The authors have investigated the effect of lead and mercury on the voltage response to light of rods, and compared these effects with those of the phosphodiesterase inhib...
