Dynamical Analysis for the Hybrid Network Model of Delayed Predator-Prey Gompertz Systems with Impulsive Diffusion between Two Patches by Li Xiang, Yurong Zhang, Dan Zhang, Zhichun Yang, Lingzhi Huang

“…Using the discrete dynamical system determined by the stroboscopic map which has a globally stable positive fixed point, we obtain the global attractive condition of predator-extinction periodic solution for the network system. Furthermore, by employing the theory of delay functional and impulsive differential equation, we obtain sufficient condition with time delay for the permanence of the network.…”

k -Fractional Variants of Hermite-Mercer-Type Inequalities via s-Convexity with Applications by Saad Ihsan Butt, Jamshed Nasir, Shahid Qaisar, Khadijah M. Abualnaja

“…This article is aimed at studying novel generalizations of Hermite-Mercer-type inequalities within the Riemann-Liouville k-fractional integral operators by employing s-convex functions. Two new auxiliary results are derived to govern the novel fractional variants of Hadamard-Mercer-type inequalities for differentiable mapping Ψ whose derivatives in the absolute values are convex. …”

Production et usage des ressources urbaines en migration : les ateliers de confection à São Paulo by Sylvain Souchaud

“…To characterize them, we target groups of South American migrants, workers and small employers inserted into the sweatshop economy. We will see how, in a metropolitan context where international migrants face difficulties entering the labor market and access to housing, workshops are organized by re-using urban fabric elements, namely certain frame configurations, and produce their own supply of housing to labor, to guarantee its cheapness and productivity. …”

(im)Material Geographies: From Poetics of Terraforming to Earth Scripts by Tymon Adamczewski

“…In this sense they can be seen as belonging to a longer and broader strain of poetic endeavours (like concrete poetry and land art) that struggle to problematise the relationship between form and meaning. The article also employs the notion of earth scripts which allows to see such poetic and artistic practices as forms of descriptions of the earth characterized by differing degrees of sensitivity to the environmental challenges posed by the Anthropocene.…”

Nano-ZnO Catalyzed Green and Efficient One-Pot Four-Component Synthesis of Pyranopyrazoles by Sunil U. Tekale, Sushma S. Kauthale, Kavita M. Jadhav, Rajendra P. Pawar

“…An efficient zinc oxide nanoparticle catalyzed one-pot, four-component synthesis of 6-amino-3-methyl-5-cyano-4-aryl-1,4-dihydropyrano[2,3-c]pyrazoles from aromatic aldehyde, malononitrile, ethyl acetoacetate, and hydrazine hydrate in aqueous medium is described. Since water was employed as the reaction medium, it serves as a green route for the synthesis of pyrano[2,3-c]pyrazoles. …”
