Euclidean Partial Semirings
The partial functions under disjointdomain sums and functional composition
is a partial semiring, an algebraic structure possessing a natural partial
ordering, an infinitary partial addition and a binary multiplication, subject to a set
of axioms. In this paper we study the Euclidean partial semirings.

Generalized Closed Sets in Ideal M Spaces
Dontchev et al. [2] introduced and investigated the notion of Igclosed
sets in ideal topological spaces as a modification of gclosed sets due to Levine [5].
The concept of ideal mspaces was introduced by AlOmari and Noiri [1]. In this
paper, we introduce and study the concept of generalized closed (Ig¤closed) sets
in an ideal mspace.

Inclusion Properties of an Integral Operator Involving
Hadamard Product
In this paper, new subclasses of analytic functions associated with
an integral operator are introduced. Inclusion properties of these subclasses are
investigated.

Boundedness of Convolution Operators on Triebel
 Lizorkin Spaces Via Fourier Transform Estimates
In this paper, we study the boundedness of some convolution operators
defined by Tf =
P
k2Z ¾k¤f on the homogeneous TriebelLizorkin spaces by Fourier
transform estimates. As applications, we improve some known results, by proving
the boundedness for singular integral operators with rough kernels on homogeneous
TriebelLizorkin spaces.

The Existence of Periodic Solutions for Second Order
Functional Differential Equations Caused by Impulses
Effects
The method is based upon the theory of coincidence due to Mawhin,
which shows that the impulse infects cause the existence of solutions. Related
examples are mentioned to support the results of this paper.
