In this issue we will talk about the importance of the supply chain. A supply chain is a network of facilities and distribution means whose function is to obtain materials, processing of these materials into intermediate ...

A lipase-catalyzed procedure is described for the one-pot conversion of carboxylic acids into substituted amides via in-situ formation of the ethyl ester and subsequent aminolysis. The procedure was optimized for the ...

At half doping, the ground state of three-dimensional manganite perovskite oxides like R1-xCaxMnO3, where R is a trivalent ion such as La, Pr, etc., is still unclear. Many experimental findings agree better with the combined ...

Assembly and stabilization of a glutathione-complexed [2Fe–2S] cluster is promoted by aggregation of glutathione. The cluster core selects the tetramer species from a collection of equilibrating solution aggregate ...

This paper presents a methodology for determining the optimal supply chain design with economic, environmental and risk management considerations. A multi-objective model based on mixed integer programming is proposed ...

In this article, we examine the role of pottery production in social and community integration processes during the Late Intermediate period (ca. CE 1000–1450). We explore this relationship through a case study of Yavi-Chicha ...
