Ethylene-norbornene copolymers were synthesized with a homogeneous catalyst system based on bis(imino) pyridine iron with the addition of diethyl zinc (DEZ) as alkyd transfer agent to promote immortal copolymerization.The addition of DEZ did not influence the catalytic activity in copolymerization with 7.5 mmol of norbornene (NB), but in the reacti
This work presents an open-loop discrete-time dynamic optimization scheme for continuous-variable impulsive control problems.This methodology can be more useful Wall Art Painting than the classical optimal control in several contexts, since it delivers control actions just in discrete times, which introduce discontinuities in the system state varia
The article is devoted to the usefulness of including the exercises based on texts of intra-company written communication in a professionally-oriented textbook for undergraduate students of engineering specialty.The issues associated with the methodological potential of exercises, designed on the basis of this texts, are discussed in terms of the m
Abstract Meaningful engagement and partnerships with people who use drugs are essential to conducting research that is relevant and impactful in supporting desired outcomes of drug consumption as well as reducing drug-related harms of overdose and Klassy Cowgirl COVID-19.Community-based participatory research is a key strategy for engaging communit
