Preparation and Chemical/Microstructural Characterization of Azacrown Ether-Crosslinked Chitosan Films
(Multidisciplinary Digital Publishing Institute, 2017)
Chemically stable porous azacrown ether-crosslinked chitosan films were prepared by reacting varying molar amounts of N,N-diallyl-7,16-diaza-1,4,10,13-tetraoxa-dibenzo-18-crown-6 (molar equivalents ranging from 0, 0.125, ...
Defect-induced room temperature ferromagnetic properties of the Al-doped and undoped ZnO rod-like nanostructure
(Elsevier, 2017)
In this work, electron paramagnetic resonance (EPR) experiment on undoped ZnO and Al doped ZnO (AZO) nanoparticles prepared by facile sol–gel method were investigated. The effects of the Al concentration on room temperature ...
A Multiplicative Bias Correction for Nonparametric Approach and the Two Sample Problem in Sample Survey
(Scientific Research Publishing, 2017)
Let two separate surveys collect related information on a single population U. Consider situation where we want to best combine data from the two surveys to yield a single set of estimates of a population quantity (population ...
Narrow Visible Emission And Narrowing Band Gap In Ho3+ -Co Doped Y2O3: Eu3+ Nanopowders Prepared Via Sol- Combustion Route.
(IOSR Journal of Applied Physics, 2017-12)
Nanocrystalline Eu3+, Ho3+co-doped Y2O3 powders with a maximum size of 9.8 nm were prepared by the sol-combustion process, using Y (NO3).6HO2 as an oxidizer, europium and holonium nitrates as activators, thiourea as a fuel ...
The Possibility of Angle Trisection (A Compass-Straightedge Construction)
(Journal of Mathematics and System Science, 2017)
The objective of this paper is to provide a provable solution of the ancient Greek problem of trisecting an arbitrary angle employing only compass and straightedge (ruler).(Pierre Laurent Wantzel, 1837) obscurely presented ...
Effects of Grafting Azacrown Ether on Thermal and Swelling Properties of Chitosan Films
(Multidisciplinary Digital Publishing Institute, 2017-11-17)
The thermal and swelling properties of a series of azacrown ether-crosslinked chitosans prepared with varying molar amounts of N, N-diallyl-7, 13-diaza-1, 7, 10, 16-tetraoxa-dibenzo-18-crown-6 (molar equivalents ranging ...
The Cube Duplication Solution (A Compass-straightedge (Ruler) Construction)
(International Journal of Mathematics Trends and Technology, 2017)
This paper objectively presents a provable construction of generating a length of magnitude;, as the geometrical solution for the ancient classical problem of doubling the volume of a cube. Cube duplication is believed to ...
Thermal Resistivity of Chemically Activated Calcined Clays-Based Cements
(Springer, 2017)
The study investigated the effects of selected potential chemical activators on thermal resistivity of calcined clay based cement mortars. 0.5 M Na2SO4 and 0.5 M NaOH were used as activator solutions. The chemical composition ...
Velocity Profiles of Unsteady Blood Flow through an Inclined Circular Tube with Magnetic Field
(Journal of Advances in Mathematics and Computer Science, 2017)
The present paper is devoted to study the flow of incompressible viscous, electrically conducting fluid (blood) in a rigid inclined circular tube with magnetic field. The blood is considered to be Newtonian fluid and the ...
Turbulent Natural Convection in an Enclosure at Varying Aspect Ratio
(International Institute for Science, Technology and Education (IISTE), 2017)
Energy transfer mechanism in most technical flows is through turbulent natural convection due to low viscosity of the fluids used in technical applications. Consequently, there is need to establish the parameters that ...
