process management (pm) is a structured, systematic approach that is adopted by firms in order to analyze, improve and control their processes. this paper has been focused on identifying and testing the effective critical success factors (csfs) in the preparation and successful implementation of process management. according that in this study by reviewing the literature and studying various re...

for a ring endomorphism $alpha$ and an $alpha$-derivation $delta$, we introduce a concept, so called skew $pi$-armendariz ring, that is a generalization of both $pi$-armendariz rings, and $(alpha,delta)$-compatible skew armendariz rings. we first observe the basic properties of skew $pi$-armendariz rings, and extend the class of skew $pi$-armendariz rings through various ring extensions. we nex...

In this paper, we introduce the concept of interval valued fuzzy weak bi-ideals of $Gamma$-near-rings, which is a generalized concept of fuzzy weak bi-ideals of $Gamma$- near-rings. We also characterize some properties and examples of interval valued fuzzy weak bi-ideals of $Gamma$-near-rings.

for an arbitrary ring $r$, the zero-divisor graph of $r$, denoted by $gamma (r)$, is an undirected simple graph that its vertices are all nonzero zero-divisors of $r$ in which any two vertices $x$ and $y$ are adjacent if and only if either $xy=0$ or $yx=0$. it is well-known that for any commutative ring $r$, $gamma (r) cong gamma (t(r))$ where $t(r)$ is the (total) quotient ring of $r$. in this...

We speed up existing decoding algorithms for three code classes in different metrics: interleaved Gabidulin codes the rank metric, lifted subspace and linearized Reed-Solomon sum-rank metric. The speed-ups are achieved by new that reduce cores of underlying computational problems decoders to one common tool: computing left right approximant bases matrices over skew polynomial rings. To accompli...

This study presented the first recorded of banded garden spider Argiope trifasciata and described for time in Baghdad city, Iraq. The specimens were collected from Al-Rashidiya sub-district north city on 26/ November/ 2021 (7:00 am- 6:00 pm) fruit gardens (orange apricot trees) agriculture lands (palm trees, crops wheat vegetables). "Argiope trifasciata" species is a member orb-weaving genus. I...

in this paper, we introduce a class of $j$-quasipolar rings. let $r$ be a ring with identity. an element $a$ of a ring $r$ is called {it weakly $j$-quasipolar} if there exists $p^2 = pin comm^2(a)$ such that $a + p$ or $a-p$ are contained in $j(r)$ and the ring $r$ is called {it weakly $j$-quasipolar} if every element of $r$ is weakly $j$-quasipolar. we give many characterizations and investiga...

263 In part one, I identify the core logical structure of the precautionary principle and distinguish it from the various key concepts that appear in the many different formulations of the principle. I survey these concepts and suggest a program of further conceptual analysis. In part two, I examine a particular version of the precautionary principle dubbed “the catastrophe principle” and criti...

Most dictionaries and glossaries of terms today are not structured. They contain many different terms, arranged in alphabetical sequence, with little or no attempt to show how the terms are related. A new IFIP "Glossary of Terms used in Production Control" has now been produced, which is structured. It is based on a classification of Production Management, of which Production Control is a part,...

let $alpha$ be an automorphism of a ring $r$. the authors [on skewinverse laurent-serieswise armendariz rings, comm. algebra 40(1)(2012) 138-156] applied the concept of armendariz rings to inverseskew laurent series rings and introduced skew inverselaurent-serieswise armendariz rings. in this article, we study on aspecial type of these rings and introduce strongly armendariz ringsof inverse ske...
