On Structures of HSpaces
A pair (X;A) of a topological space X and a topological ring A is called
an Hspace, if for each closed subset F of X and x =2 F, there exists f 2 CA(X)
such that f(x) 6= oA and F µ Z(f) and a topological space X is called a Vspace,
[4], if for points a; b; c, and d of X, where a 6= b, there exists a continuous functions
f of X into itself such that f(a) = c and f(b) = d. In this paper we investigate
some properties of Hspaces. In addition to , we show that every Hspace is not a
Vspace.

Global Stability and Bifurcation Analysis of a Harvested Stage
Structure PredatorPrey System with Linear Functional Response
The global properties of a harvested stagestructured predatorprey
model with linear functional response and constant delay are studied using Lyapunov
functions and LaSalle’s invariance principle. It is shown that time delay and
the harvesting effort can cause a stable equilibrium to become unstable. A condition
which leads to the extinction of the predators is indicated.

Decomposition of Continuity Via Grills
In this paper, we introduce the notions of G®open sets, Gsemiopen
sets and G¯open sets in grill topological spaces and investigate their properties.
Furthermore, by using these sets we obtain new decompositions of continuity.

Longitudinal Data Analysis Using Generalized Maximum Entropy
Approach
Marginal generalized linear models are frequently used for the analysis
of repeated measurements and longitudinal data. During the last three decades,
researchers used parametric, nonparametric as well as Bayesian methods as useful
approaches to model such kind of data.

Comparison of Relative Risk Functions of the Rayleigh: Distribution
Under TypeII Censored Samples: Bayesian Approach
Based on complete as well as type II censored samples, the Bayes’ estimators for
the parameter and reliability function of Rayleigh distribution are obtained. These estimators are
obtained on the basis of squared error loss function and LINEX loss function.
