CLUSTER POINT OF NET AND ISOLATED MAPPING

In mathematics, more specifically generally topology and related branches, a net or Moore-Smith sequence may be a generalization of the notion of sequence. In essence, a sequence may be a function with domain the natural numbers and within the context of topology, the co domain of this function is typically any mathematical space . However, within the context of topology, sequences don't fully encode all information a few function between topological spaces

CONVERGENCE OF NET IN TOPOLOGICAL SPACE

The word topology is derived from Greek word “Topos” meaning “surface” and “Logos” meaning “Discourse” or “Study”. Topology thus literally means the Study of Surfaces. Its English form “Topology” was introduced in 1883 within the journal nature to differentiate . The term “net” was coined by John L. Kelly. Nets are one among the various tools utilized in topology to generalize certain concepts which will only be general enough within the context of metric spaces. In mathematics, more specifically in general topology and related branches, a net or Moore-Smith sequence is a generalization of the notion of sequence. In essence, a sequence is a function with domain, the natural numbers and within the context of topology, the co-domain of this function is usually any topological space. However, in the context of topology, sequ

ULTRANET AND PROPERTIES OF NET

We will study some of the basic concepts about vectors various operations on vectors, their algebraic and geometric properties. These two types of properties, when considered to gather give full realizations to the concepts of vectors, and lead to their vital applicability in various areas

A STUDY ON CENTRE OF GRAVITY

This paper proposes a simple and easy methods for determining the centre of gravity of a motionless object. A human’s Centre of gravity can change as he takes on different position, but in many other objects, it is a fixed location. Here the uniqueness of centre of gravity is discussed. Moreover,the general formula for determining the centre of gravity, centre of gravity by integration, centre of gravity of a compound body and remainder is also determine

BIOREMEDIATION OF COPPER (II) FROM AQUEOUS SOLUTION USING TAMARIND KERNEL POWDER

Heavy metal pollution is nowadays one of the most important environmental concerns. Anthropogenic activities like metalliferous mining and smelting, agriculture, waste disposal or industry discharge a variety of metals such as Ag, As, Au, Cd, Co, Cr, Cu, Hg, Ni, Pb, Pd, Pt, Rd, Sn, Th, U and Zn, which can produce harmful effects on human health when they are taken up in amounts that cannot be processed by the organism. Physical and chemical methods have been proposed for the removal of these pollutants. Conventional methods to remediate heavy metals contaminated site are excavation and solidification/ stabilization, these technologies are suitable to control contamination but not permanently remove heavy metals. Nevertheless, they have some disadvantages, among them cost-effectiveness limitations, generation of hazardous by-products or inefficiency. Biological methods solve these drawbacks since they are easy to operate, do not produce secondary pollution. Heavy metals having relatively high density are toxic at low concentration. Microorganisms and plant are usually used for the removal of heavy metals. Bioremediation is increasingly considered for clean-up of metal contaminated and polluted ecosystem. All the metals are toxic, but some of these are useful in low concentration. These large verity of heavy metals cause serious water pollutio
