On the class of $k$-quasi-$(n,m)$-power normal operators

Abstract

We introduce a family of operators called the family of k-quasi-(n, m)-power normal operators. Such family includes normal, n-normal and (n, m)-power normal operators. An operator T ∈ B(H) is said to be k-quasi-(n, m)-power normal if it satisfies

Phytochemical Activities of Conocarpus Erectus: An Overview

“…The size of silver nano particles was examined 10-70nm in range. A greater value of phenolic content up to 296± 9µg/g was observed in Methanolic extract of C. erectus as compared to 185 ± 6 µg/g in N. indicum (Ahmed et al, 2016a). Therefore, Conocarpus erectus was a high-quality reducing agent because of its higher value of phenolic content and make the whole procedure non-hazardous and green method.…”

Therefore, Conocarpus erectus was a high-quality reducing agent because of its higher value of phenolic content and make the whole procedure non-hazardous and green method, (Ahmed et al, 2016a). Naturally, heavy metals are present in the soil, but environment is being contaminated because of other local source like traffic, industry, combustion of fossil fuels.…”

A new hyperchaotic complex system and its synchronization realization

“…In 2008, Mahmoud et al constructed a new hyperchaotic complex system by extending the state feedback controller and introducing the idea of complex cycles [16]. Gamal M Mahmoud et al constructed the hyperchaotic Chen system and the hyperchaotic Lüsystem in 2007 and 2009, respectively [17,18]. In 2012, Emad E. Mahmoud added a linear controller to the complex Lorenz chaotic system and constructed another form of the complex Lorenz chaotic system with 7 dimensional(7D) [19].…”
