Most of the perturbation methods are developed to find the periodic solutions of nonlinear systems with small nonlinearities, transients are not considered. In 1947, first Russian scientists Krylov and Bogo Liubov introduced ...

This thesis Centre’s on a class of certain pseudo complemented partial lattices. This partial lattice is said to be a JP-semilattice. An algebraic structure S = (S, /\, V), where (S, /\) is a semilattice and V is a partial ...

Two types of Sajna leaves, small and large sized were analysed to obtained a comparative date on their chemical composition and nutritive values at different maturity levels. The large sized leaves contained higher amount ...

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 ...

The reduction of infant and child mo11ality in the developing countries is one or the most substantial achievements of human kind. However, in spite of various effective intervention programs, the infant and child mortality ...

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 ...

The research work presented in this thesis deals with the preparation and characterization of some new complexes of the second transition metal ions (Zr4+, Ag+ and Cd2+) with the new solvent execration reagent, LIX84 ...

This thesis studies the nature of a sectionally pseudocomplemented distributive nearlattice. By a nearlattice S we will always mean a meet semilattice together with the property th9.t any two elements possessing a common ...

Betel leaf (Piper betel) is a tropical creeper and most important herb in Bangladesh. The nutrient compositions such as protein, lipid, total sugar, reducing sugar, non­reducing sugar, starch, chlorophyll, crude fibre, ...

In many branches of Mathematics, a strategy for study of the mathematical entities is to view them as being made up of simpler entities in one or more ways. The task is then divided into two parts: (i) identifying and ...
