Nitrification is known as one of the most sensitive processes affected when activated sludge is exposed to antimicrobial silver nanoparticles (AgNPs). The impact of AgNPs and their released silver ions (Ag þ ) on the abundance, activity, and diversity of different nitrifying bacteria in wastewater treatment plants (WW…
Simple, rapid, plasma-assisted synthesis of large-area arrays of vertically-aligned carbon nanowalls on highly-porous, transparent bare and gold-coated alumina membranes with the two pore sizes is reported. It is demonstrated that the complex patterns of vertically aligned nanowalls can nucleate and form different mor…
A B S T R A C T The present communication deals with the important cyanobacterium Oscillatoria perornata f.attenuata. This cyanobacterium was collected from Kadalundi (Kerala), India, which is seen in associated with mangroves. The present report of cyanobacterium is the first record on the occurrence of Oscillatoria…
The recent progress is reviewed and future prospects of silicon photonics in next generation communication and computing systems are probed. Leverage is many-billion-dollar complementary metal-oxide-semiconductor (CMOS) industry, silicon photonics has promising prospects for realising very large-scale electronic and p…
In this work, effect of addition sodium chloride(NaCl) on some A.C and D.C electrical properties of polystyrene have been investigated .For this purpose ,the PS films with (NaCl) additive prepared with different percentages and different thicknesses. The experimental results showed that the dielectric constant, dielec…
The assessment of common cause failure (CCF) is necessary for reducing the uncertainty during the process of probabilistic safety assessment. A basic unavailability assessment method is an approach for the quantitative analysis of CCF modeling using Bayesian probability, in which the estimation of parameters is more a…
Polymeric copper(II), zinc(II) and cadmium(II) complexes of polydentate ligand 1,5-bis(2- pyrimidineaminoethylidene)-2,4-dihydroxy benzene (H2bispdb) and 1,5-bis(p-tolylaminoethylidene)-2,4- dihydroxy benzene (H2bistdb) of compositions (CuL(H2O)2)n and (ML)n, (M= Zn II or Cd II and H2L= H2bispdb or H2bistdb) were synt…
Abstract — In this paper Eringen’s nonlocal theory of elasticity is applied to study the wave properties of single walled carbon nanotubes. The effects of wave number and nonlocal scaling parameter (e0a) on the frequency, phase velocity and group velocity are discussed for a particular material of carbon nanotube.
SUMMARY As to the importance of permeability in the preservation process of solid woods, the effects of diffusion drying schedule with three different initial moisture contents (MC) on fluid flow in the sapwood and heartwood of paulownia wood ( Paulownia fortunei) were studied here. Boards with initial MCs of 113 % (D…
In this work, nanostructured biocomposite fibers and films with cellulose nanofibers (CNF), cellulose nanocrystals (CNC) and chitin nanocrystals (ChNC) were prepared using solutions mixing followed by electrospinning and melt compounding. The main processing challenges for these materials were to find parameters for:…
There was studied the process of solid objects with 50 radius penetration into aluminum solid bodies. Analysis of experimental results showed that the hydrodynamic model cannot be used as a basis for the penetration process description. It is shown that in case of small particles there occurs a specific mechanism of p…
A Microbial Fuel Cell is a device that can be used to exploit the bio-electrochemical interactions between the bacteria and the organic matter present in the substrate to produce electricity. For doing so, the bacteria oxidize the organic matter and deposit the electrons at a suitable electrode. Despite the promising…
This Paper also give the Various range parameter of temperature of using fuel cell and including current voltage power characteristic , uniformity of cell unit voltage, Gas, pressure impact and air flux impact operating temperature of fuel cell has been change in anode and cathode side. This paper also give the experi…
In this paper, a theoretical study of several conju gated aromatic compounds based on several pyrroleis reported using Density Functional Theory method (DFT). Theor etical calculation has been carried out in order to characterize their stability, geometric and electro nic properties. In fact, substituent nature, numbe…
This study aims to test recent developments for advancing the isotope diffusive exchange technique in order to adapt it to high salinity porewaters and, in a more general way, to solutions with low water activities. This report documents work performed to: 1) investigate factors that might influence the results of the…
The Department of Energy’s (DOE) Office of Nuclear Energy is currently preparing a national transportation plan for a prototype campaign for spent nuclear fuel (SNF) shipments from decommissioned reactor sites to a pilot interim storage facility. Two previous national transportation plans, prepared by the now defunct…
Recyclability is the ability of a material to reacquire the same properties it had originally. The aim of this work was to verify the recyclability of three printing and writing papers, from the characteristics of their fibers after two recycles. Three ECF bleached kraft eucalyptus commercial bond papers from Argentin…
The main objective of the presented research is to develop a model in order to predict fracture of asphalt road surface impacted by an automobile tire stud. As a result of the analysis it is demonstrated that the critical automobile speed leading to creation of fracture in asphalt does depend on combination of asphalt…
Polymer based organic thin film transistors (OTFTs) can be used in radio-frequency identification (RFID) tags, flexible displays, medical sensors, memory devices, etc.; but their low charge carrier mobility has limited many applications. Recently, several classes of π-conjugated polymers having electron donor (D) and…
In this project, fundamental studies of the Pt/carbon catalyst degradation mechanisms and degradation rates are conducted and correlated with membrane transport properties and operational conditions. The fundamental studies are used to facilitate the development and refinement of membrane model implementation within t…
