In this work, we Siudy door Spaces, and rve approve several theorem about this spaces. Also we introduce anerv conce4pt, namely, Semi-door spaces, and we prove several theorem about this nerv concept.
In this paper we present the definitions of T-ct-operator, (T,L) cr-continuous and (T, L) cr-homeomorphism map, and found some theorems about them.
The main purpose of this paper is to study the algebraic properties of a multiplication R-module Mwhenever the space lvla{fuL) of all maximal submodules of M is an irreducible space. We prove that Mar(lul) is irreducible if and only if the Jacobson radical J(0) of tvI is prime and if J(0)=0then Max(M) is irreducible if and only if I/is irreducible.Also we investigate the relation between Mar(M and Mar( R) if one of them is irreducible.
Thin films of CdS:Ag have been prepared using chemical spray p1'rol1'sis. From the absorption spectra we calculate the absorptance.absorption coefticient, and kinds of transition. These films rvere exposed to a specified absorbed dose of positron, it rvas found that the irradiation aflbcted the studied optical parameters.

However, these equations have been set up in a way such that it can be used for all over the sorts of blocks. Thereafter, the system of, these eqtrations were solved numerically using the forth order Runge-Kutta method to deduce the blocks trajectory and any, required observable of the ejected blocks. The results of comparison have clearly shown that, the introduced procedure has an excellent efficiency u'ith high accuracy. Finally a comprehensive investigation was carried out to revel the influence of varying the physical and geometrical parameters on.the behavior of the ejected blocks.

Depending on the solution of Non-Linear Schrddinger Equation (NLSE), the fundamental soliton properties can be studied. In this *ork the solution ot the NLSE rvas applied to describe the pulse propagation in single mode optical fiber (SNtOF), and to investigate some soliton-'soliton interactions rvith antl rvithottt gain effect. As a result, it is found.that tn'o neighboring soliton-ptllses can pqsh-pull along their propagrtion direction' The interactions ard sontetintes strongly dependent on the relative phase differences of larrnched soliton Pulse trains. Meanrvhile, some relltil'e initial phase difference provides better putse train propagation. for the benefit of optical fi ber conrmunication systenls.

This is been expanded into a larger and broader range of skin treatments and renamed Skinsmiths. The range is made from the latest generation of ingredients proven to protect and those that help to control oils and maintain a matt finish. This balance of clinical effectiveness and cosmetic mindfulness is expressed by its graphic identity, created by Auckland studio Akin, in the meeting of a bold black logotype and in the material interaction and contrast between uncoated paper and distinctive glossy print finish.October 21, 2019 (FPRC) -- SHO has launches it's commercial space website in Singapore.
