Ultrafine Metallic Particles as Inducers of Digestive Processes in Rumen: Dry Matter Digestibility of Feed and Enzymatic Activity. [PDF]
Scientifica (Cairo)The ban on the use of antibiotics in animal husbandry encourages an active search for highly effective alternatives with additional properties, one of which is ultrafine particles (UFP) of metallic nature. The objective of the presented work was to conduct a comprehensive analysis of newly synthesized UFP Co3O4 and Mn2O3, including determination of ...

Delta and Theta Generalized Closed Sets in Bitopological Spaces [PDF]
Assiut University Journal of Multidisciplinary Scientific Research, 2016 In this paper we introduce new two types of generalized closed sets in bitopologicalspaces and study some of it's properties and it's relations with other kinds ofgeneralized closed sets.

T(α,β)‐spaces and the Wallman compactification
International Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 68, Page 3717-3735, 2004., 2004 Some new separation axioms are introduced and studied. We also deal with maps having an extension to a homeomorphism between the Wallman compactifications of their domains and ranges.

Semi‐precontinuous functions and properties of generalized semi‐preclosed sets in topological spaces
International Journal of Mathematics and Mathematical Sciences, Volume 29, Issue 2, Page 85-98, 2002., 2002 Andrijević (1986) introduced the class of semi‐preopen sets in topological spaces. Since then many authors including Andrijević have studied this class of sets by defining their neighborhoods, separation axioms and functions. The purpose of this paper is to provide the new characterizations of semi‐preopen and semi‐preclosed sets by defining the ...

Weak and strong forms of irresolute maps
International Journal of Mathematics and Mathematical Sciences, Volume 23, Issue 4, Page 253-259, 2000., 2000 We consider new weak and stronger forms of irresolute and semi‐closure via the concept sg‐closed sets which we call ap‐irresolute maps, ap‐semi‐closed maps and contra‐irresolute and use it to obtain a characterization of semi‐T1/2 spaces.

p‐topological and p‐regular: dual notions in convergence theory
International Journal of Mathematics and Mathematical Sciences, Volume 22, Issue 1, Page 1-12, 1999., 1999 The natural duality between “topological” and “regular,” both considered as convergence space properties, extends naturally to p‐regular convergence spaces, resulting in the new concept of a p‐topological convergence space. Taking advantage of this duality, the behavior of p‐topological and p‐regular convergence spaces is explored, with particular ...

International Journal of Mathematics and Mathematical Sciences, Volume 22, Issue 2, Page 239-249, 1999., 1999 The aim of this paper is to study the class of θ‐generalized closed sets, which is properly placed between the classes of generalized closed and θ‐closed sets. Furthermore, generalized Λ‐sets [16] are extended to θ‐generalized Λ‐sets and R0‐, T1/2‐ and T1‐spaces are characterized.

Two types of separation axioms on supra soft topological spaces
Demonstratio Mathematica, 2019 In 2011, Shabir and Naz [1] employed the notion of soft sets to introduce the concept of soft topologies; and in 2014, El-Sheikh and Abd El-Latif [2] relaxed the conditions of soft topologies to construct a wider and more general class, namely supra soft

Two countable, biconnected, not widely connected Hausdroff spaces
International Journal of Mathematics and Mathematical Sciences, Volume 22, Issue 2, Page 251-258, 1999., 1999 We construct two countable, biconnected spaces, not widely connected, not having a dispersion point, and not being strongly connected. The first is Hausdorff and the second is Urysohn and almost regular.
