The effects of high temperature on mechanical properties of cementitious composites reinforced with polymeric fibers
(Elsevier Sci Ltd, 2013)
Polymeric fibers are cheap and popular materials used in the concrete industry, and they may improve the mechanical properties of cementitious composites under high temperature. In this study, three different types of ...
Preparation of a New Sorbent, Cetyltrimethylammonium Bromide (CTAB)-Modified Obsidian, for the Separation and Preconcentration of Pb(II) and Cd(II) Ions in Food and Water Samples
(Atomic Spectroscopy Press Ltd, 2014)
Cetyltrimethylammonium bromide (CTAB)-modified obsidian (CTAB-OB) was utilized as a new sorbent for the separation and preconcentration of Pb(II) and Cd(II) ions by solid phase extraction in some environmental samples prior ...
SELECTIVE SEPARATION, PRECONCENTRATION AND DETERMINATION OF Pd(II) IONS IN ENVIRONMENTAL SAMPLES BY COPRECIPITATION WITH A 1,2,4-TRIAZOLE DERIVATIVE
(Chem Soc Ethiopia, 2015)
A simple, sensitive, facile and low cost methodology, combined with flame atomic absorption spectrometry (FAAS), was employed to evaluate the selective separation and preconcentration of Pd(II) ions in environmental samples ...
The Arabidopsis thaliana FASCICLIN LIKE ARABINOGALACTAN PROTEIN 4 gene acts synergistically with abscisic acid signalling to control root growth
(Oxford Univ Press, 2014)
Background and Aims The putative FASCICLIN-LIKE ARABINOGALACTAN PROTEIN 4 (At-FLA4) locus of Arabidopsis thaliana has previously been shown to be required for the normal growth of wild-type roots in response to moderately ...
On Well-posedness of Source Identification Elliptic Problem with Nonlocal Boundary Conditions
(Amer Inst Physics, 2021)
We study the well-posedness of the source identification problem for the two dimensional elliptic differential equation with nonlocal boundary conditions. Applying operator approaches, the exact estimates for the solution ...
ASSESSMENT OF KINETICS, THERMODYNAMICS AND EQUILIBRIUM PARAMETERS OF CR(VI) BIOSORPTION ONTO Pinus brutia TEN
(Wiley, 2014)
The aim of the present study was to investigate the sorption potential of pine bark (Pinus brutia Ten.) for removal of Cr(VI) ions from aqueous solutions. The biosorption characteristics of Cr(VI) ions onto bark biomass ...

(Indian Acad Sciences, 2010)
Stochastic seismic analysis of long-span bridges with Carbon fibre reinforced polymer (CFRP) cables are presented in this study through combination of the advantages of the perturbation based stochastic finite element ...
Adsorption of Phenol from Aqueous Solution on a Low-Cost Activated Carbon Produced from Tea Industry Waste: Equilibrium, Kinetic, and Thermodynamic Study
(Amer Chemical Soc, 2012)
The ability of activated carbon which was produced by chemical activation using zinc chloride from tea industry wastes (TIWAC) to adsorb phenol molecules from aqueous solution was tested by equilibrium, kinetic, and ...
Equilibrium, kinetics, and thermodynamic evaluation of mercury (II) removal from aqueous solutions by moss (Homalothecium sericeum) biomass
(Wiley, 2015)
In the present research, Homalothecium Sericeum was utilized for the first time as an effective and readily available adsorbent in removal of Hg(II) ions from aqueous solutions through a batch adsorption technique. The ...
Investigation of mechanical and mineralogical properties of mortars subjected to sulfate
(Elsevier Sci Ltd, 2010)
The durability can be described as concrete's resistance to the destructive influences of a medium containing acid, sulfate and/or various chemicals and mechanical effects. The main objective of this study is investigation ...
