Harmonic and Anharmonic Oscillator Models for Pure Vibrational Infrared Spectroscopy of Diatomic Molecules
Authors : Rohit Singh,


In molecular vibrational infrared spectroscopy, absorption spectra arise from molecular vibration and correspond to transitions between the vibrational energy levels associated with a given electronic state of the molecule. The vibrational transitions, which fall in the near infrared region, are induced through the interaction of the molecular electric dipole with the electric vector of...

Mechanical Properties of novel hardened cement paste reinforced with Multi-Walled Carbon Nano-Tubes (MWCNTs) and Glass Fibers Nano material
Authors : Sandhya R. Jalgar,Anand M. Hunashyal,S.N. Mathad,Raghavendra Jalgar,


To improve the mechanical and durability properties of ordinary Portland cement (OPC) mortar and paste, the incorporation of multi walled Carbon nanotubes (MWCNTs) and their dispersion procedures, functionalization, and ultra sonication have been intensively implemented. Most of the studies showed significant enhancements in the mechanical properties of OPC mortar or paste; however, others showed...

Brauer’s Fixed Point Theorem
Authors : Dragan Obradovic,Lakshmi Narayan Mishra,Vishnu Narayan Mishra,


The primary goal of the paper is to deliver a simple proof of equivalence between Brouwer’s fixed point theorem and the existence of equilibrium in a simple exchange model with monotonic consumers. To achieve this end, we discuss some equivalent formulations of Brouwer’s theorem and prove additional ones, that are ’approximating’ in character or seem to be better suited for economic...

Increasing the Density of Field-Effect Heterotransistors in an Amplifier Flipped Voltage Follower Mirrors with Account of Miss-Match Induced Stress
Authors : E.L. Pankratov,


In this paper, we introduce an approach to increase density of field-effect transistors framework current mode instrumentation amplifier flipped voltage follower mirrors. The approach we consider for manufacturing of the inverter in heterostructure with specific configuration. Several required areas of the heterostructure should be doped by diffusion or ion implantation. After that dopant and...

 Dyeing of Cotton Fabric with Natural Dye Extracted from   Egyptian Cotton Leaves
Authors : Yasser A. Abd-El-Baset,Alaa Heikal,Salah M. Saleh,


: Cotton leaves have been used to extract natural dye for dyeing of Egyptian cotton variety Giza 86 fabric and its blend with polyester 50:50, using different mordants such as iron (II) sulfate, copper (II) sulfate, and alum. The exhaust dyeing method was utilized using the pre-mordant technique. It is observed that both fabric samples can be dyed in different colors and depth of shades with...

Pre-Local Function in Ideal Topological Spaces
Authors : Fadhil Abbas,


The aim of this paper is to introduce the notation of pre-local function A p ∗ (I, τ) by using preopen sets in an ideal topological space (X, τ, I). Some properties and characterizations of a pre-local function are explored Pre-compatible spaces are also defined and investigated. Moreover, by using A p ∗ (I, τ) we introduce an operator ψ: P(X)→τ satisfying ψ(A) = X−(X −...
