Over the past 25 years, I have been immersed in research in Algebra and more particularly in ring theory. I embarked on writing this book on Smarandache rings (Srings) specially to motivate both ring theorists and Smarandache algebraists to develop and ...

New azobenzene liquid crystal with dihydropyrazole heterocycle and photoisomerization studies [PDF]
New azobenzene derivatives with dihydropyrazole heterocycle have been prepared and characterized. According to thermal polarizing microscopy and differential scanning calorimetry studies, the compounds consisting of four linearly linked rings and a long ...

In this book we define the new notion of neutrosophic rings. The motivation for this study is two-fold. Firstly, the classes of neutrosophic rings defined in this book are generalization of the two well-known classes of rings: group rings and semigroup ...

The main concern of this book is the study of Smarandache analogue properties of near-rings and Smarandache near-rings; so it does not promise to cover all concepts or the proofs of all ...

Drak Is Required for Actomyosin Organization During Drosophila Cellularization
The generation of force by actomyosin contraction is critical for a variety of cellular and developmental processes. Nonmuscle myosin II is the motor that drives actomyosin contraction, and its activity is largely regulated by phosphorylation of the ...

5-[3-(2,5-Dimethoxyphenyl)prop-2-enylidene]-1,3-diethyl-2-thioxohexahydropyrimidine-4,6-dione
1,3-Diethyl-2-thiobarbituric acid reacts with 2,5-dimethoxybenzaldehyde to form the title Knoevenagel product, C19H22N2O4S. In the compound, the two six-membered rings at either end of the three-membered –CHCHCH– chain are nearly ...

Abstract Let R be a finite chain ring. In this note we introduce R-designs with repeated blocks in the Grassmanian of all submodules over a chain ring R of given shape κ. We prove that for some sufficiently large t − ( n , k , l ) R-designs with repeated blocks do exist for all integers t , k , n with 0 t k n − t

On Automorphism Groups of Finite Chain Rings [PDF]
A finite ring with an identity is a chain ring if its lattice of left ideals forms a unique chain. Let R be a finite chain ring with invaraints p,n,r,k,k′,m. If n=1, the automorphism group Aut(R) of R is known. The main purpose of this article is to study the structure of Aut(R) when n>1. First, we prove that Aut(R) is determined by the automorphism
