Cupric oxide (CuO) and Cadmium sulphide (CdS) thin films have been deposited on glass substrates by chemical spray pyrolysis technique and their structural, electrical and optical properties were studied. Film growth aspects ...
Investigations have been carried out on spray pyrolysed
undoped and indium doped ZnO thin films for the thickness range
700-4000 A. The undoped ZnO thin films were found to be nonstoichiometric
but homogeneous and ...
In order to find the approximate numerical solution to a system of nonlinear equations as well as an integral and a differential operator equations, Newton's algorithm is widely used. L. V. Kantorovich [1948] and Moore ...
This thesis studies the nature of distributive nearlattices. By a nearlattice S we will always mean a (lower) semilattice which· has the property that any two elements possessing a common upper bound,have a supremum, Cornish ...

In this work, we deal with the two types of variational inclusions. Firstly, we consider
the variational inclusion problem of the form
0 ∈ ζ(¯s) + g(¯s) + ξ(¯s), (A)
where S and T are Banach spaces, ζ : S → T is ...

Turbulence means agitation, commotion and disturbance. This definition is, however too general and does not suffice to characterize turbulent fluid motion in the modern sense. Osborn Reynolds in the study of turbulent ...
This thesis studies extensively the finitely generated n-ideals of a lattice. The idea of n-ideals in a lattice was first introduced by Cornish and Noor in studying the kernels around a particular element n, of a skeletal ...

Fixed point theory has fascinated hundreds of researchers since 1922 with the celebrated Banach’s fixed point theorem. Fixed point iterative procedures are one of the early achievements of fixed point theory for their ...

Infant and under-five mortality are the sensitive indices of development and often
reflect a country's quality of life. But there is little understanding of whether
Bangladesh will be capable of achieving all of the ...
A theoretical study of oxygen diffusion process through living tissues and its various consequences have been presented. In this aspect we have reviewed some physiological terms and fundamental lows of diffusion.
A ...
This is an elaborate discussion of main theme ideas and the condition in "Fluid mechanics", which help us to realized a clear concept of the background and elements of various viscous Newtonian and non-Newtonian flow ...

This thesis studies the nature of standard n-ideals of a lattice. The idea of n-ideals in a lattice was first introduced by Cornish and Noor. For a fixed element n of a lattice L, a convex sublattice containing n is called ...
Turbulent motions are very common in nature. The theory of turbulent motion has received considerable attention in recent developments of high-speed jet aircraft, plasma physics and chemical engineering. The formation of ...
The first chapter is a general introductory chapter and gives the general idea of turbulence, distribution functions and their principal concepts. Some results and theories which are needed in the subsequent chapters have ...
Transition metal chelates of dithiocarbazic acid, its S-alkyl/aryl esters and their Schiff bases have been studied, mainly due to their potential anticancer, antibacterial, antifungal, antimoebic, nonlinear optical and ...

This thesis describes the synthesis and characterization of Nickel(II), Cu(II), Zn(II) and
Cd(II) complexes of 4-n-octyloxybenzoylhydrazine in presence of various aldehydes.
The lignand precursor 4-n-octyloxybenzoylhydrazine ...

Functional groups increase the utility of polymers and are fundamental to the development of many aspects of structure-property relationships. Reactive end- and mid-functionality play an important role in the properties ...
Recently scientists gave special attention to the synthesis of transition metal complexes due to their catalytic, biological mesogenic and paramagnetic properties. Hydrazone ligands and their complexes have pronounced ...
