Dual Annihilators in Bounded BCKAlgebras
In this paper, for any two subsets A and C of a bounded BCKalgebra X, the concept of dual annihilator of A with respect to C, denoted by (C : A)^{d}, is introduced and some related properties are investigated. It is proved that if A is a dual ideal and C a normal ideal of an involutory BCKalgebra X, then (C : A)^{d} is the relative pseudocomplement of A with respect to NC. Moreover, applying the concept of dual annihilator, the involutory dual ideal with respect to an ideal is defined, and it is shown that the set of all involutory dual ideals with respect to a normal ideal forms a distributive lattice.

On DMetacompactness in Bitopological Space
In this paper we define pairwise Dmetacompact spaces and study their
properties and their relations with other topological spaces. Several examples are discussed and many will known theorems are generalized concerning metacompact spaces.

BadeProperty; Survey and Comparison with λProperty, RussoDye Theorem and Extremally Richness
In this article, we survey a geometric property, called Badeproperty,
originally introduced by William Bade. First, we review Bade's work in normed linear spaces. Next, we illustrate various interesting results of Badeproperty in the spaces of convergent sequences established by Aizpuru. Then, we investigate Badeproperty in comparison with some other geometric properties, such as λproperty due to Aron and Lohman, RussoDye Theorem and extremally richness in C*algebras, JB*algebrs/triples and JBW*triples.

On Almost Contra e*θContinuous Functions
The aim of this paper is to introduce and investigate some of fundamental properties of almost contra e*θcontinuous functions via e*θclosed sets which are defined by Farhan and Yang [15]. Also, we obtain several characterizations of almost contra e*θcontinuous functions. Furthermore, we investigate the relationships between almost contra e*θcontinuous functions and seperation axioms and
e*θclosedness of graphs of functions.
