On Casaro Sequence Space of Fuzzy Numbers Defined by a Modulus Function

Ayhan Esi, Vakeel A. Khan
The main purpose of this paper is to introduce the sequence space cesF(f, p) of sequence of fuzzy numbers defined by a modulus function. Furthermore, some inclusion theorems have been discussed.

Cosmic Redshift, Temperature, Growth Rate and Age in Stoney Scale Black Hole Cosmology

U. V. S. Seshavatharam, S. Lakshiminarayana

Throughout the cosmic evolution, currently believed cosmic “critical density” can be shown to be a default result of the “positively curved” light speed rotating black hole universe “mass density”. As there is no observational or experimental evidence to Friedmann’s second assumption, the density classification scheme of Friedmann cosmology must be reviewed at fundamental level and possibly can be relinquished. With cosmic light speed rotation galactic r

Synthesis and Characterization of Graft Co-Polymers of Sisal Fiber with Binary Vinyl Monomers

Vijay K. Kaushik, Mukesh Goyal
In this paper morphological transformation of sisal fiber by graft copolymerization with methyl acrylate and its binary mixture with acrylic acid (AAc), vinyl acetate (VA) and n-butyl acrylate (BuA), using FAS-KPS initiator, under influence of microwave radiations has been reported. Optimum reaction conditions for maximum graft yield were kept same as that in case of grafting of principal monomer. Maximum grafting has been observed in case of sisal-g-poly(MA VA). The Graft copolymers thus...

Exploring Structured Thematic Inquiry in Social Research

Bennie Berkeley
The overall objective of this paper is to demonstrate the relevance of deduction (with/out falsification) to qualitative research. It provides the reader with a concise synopsis of an alternative approach to qualitative research enquiry. The philosophy is supported by Hyde [1] who believes that both qualitative and quantitative research possess deductive and inductive components. It supports this by proposing that a quasi-deductive approach based on fo...

Quasinilpotent Part of w-Hyponormal Operators

Mohammad Rashid
For a w-hyponormal operator T acting on a separable complex Hilbert space H, we prove that: 1) the quasi-nilpotent part Ho(- λ) is equal to...

Comparison of the Affinity Chromatography and the Ion Exchange Chromatography in the Isolation of Bovine Immunoglobin G

Mrigendra Rajput, Shimaa M. G. Mansour, Lyle J. Braun, Mahmoud Darweesh, Neelu Thakur, Christopher C. L. Chase
The purified Immunoglobulin G (IgG) is effectively used in passive immunization. There are various methods to isolate the IgG from serum, with its own advantages and disadvantages. In the current study, a comparative efficacy of the affinity chromatography using Protein A—Sepharose and ion exchange chromatography using DEAE Sephadex A50 was done with regard to yield and purity of IgG. Both methods were found equally effective in isolation of pure IgG with similar recovery, indicating that resear...

Response of Different Durum Wheat (Triticum turgidum Var. Durum) Varieties to Added Nitrogen Fertilizer

Miesho Belay
Twelve durum wheat genotypes were evaluated for their grain yield and related traits using two rates of nitrogen fertilizer application (69 kg N ha1 and 115 kg N ha1) in a randomized complete block design with three replications. The experiment was done on Vertisol at Adet Agricultural Research Center in the main cropping season 2009. All agronomic traits respond positively to applied nitrogen rates. The highest grain yield (33.8 Qt·ha...

Compact Operators on Hilbert Spaces

Sara Nozari
In this paper, we obtain some results on compact operators. More specially, we prove that if T is a unitary operator on a Hilbert space H, then it is compact if and only if H has a finite dimension. Also, we prove that, if H is a Hilbert space with Heine-Borel property, then .

A Comparative Study of the Advance of the Newtonian Component of Mercury’s Perihelion by Numerical Analysis and Perturbation Theory

Rajat Roy
A new numerical evaluation of the Newtonian component of Mercury’s perihelion advance over more than two centuries starting from about the year 2000 is made. Results are given for about the last 30 years of this interval. Comparison with perturbation theory calculation results indicates necessity of revision of previously held estimates of this quantity.

Hydrodynamical Phenomena at Preparation of Earthquake

Igor Petrovich Dobrovolsky
Variations in level of fluid in wells caused by Earth tides and earthquakes are governed by two leading processes: deformation of medium and filtration. These processes are described by identical systems of equations and are united by the term “hydrodynamical phenomena”. The exact solution is obtained for the problem of level variations in wells due to Earth tides. The similar problem is solved for short-term precursors of a tectonic earthquake. Results are consistent with data of field observat...
