The optimal tuning of a mechanical system in terms of torsional dynamics is a very important function of the flexible shaft coupling, built in the system.Therefore, a flexible coupling with suitable dynamic properties has to be carefully chosen for each specific application.The main advantage of the pneumatic flexible shaft couplings, that is, tors
In this work, we reported the investigation of diamond-like carbon (DLC) coating on the inner surface of polyethylene terephthalate (PET) bottles by Microwave Plasma Enhanced Chemical Vapor Deposition to improve their barrier properties.We used 2.45 GHz microwave to generate plasma, acetylene (C2H2) and argon (Ar) were used as monomer gas and dilut
Reservoir characterization and asset management require comprehensive information about formation fluids.In fact, it is not possible to find accurate solutions to many petroleum engineering problems without having accurate pressure-volume-temperature (PVT) data.Traditionally, fluid information has been obtained by capturing samples and then by meas
Background While children with Autism Spectrum Disorder show heterogeneous cognitive profiles, they share common deficits in social-cognitive abilities and executive function.Moderate endurance exercise is known to elicit changes in the psychophysiological state, which can translate into immediate, but transient benefits for both cognitive domains.
Background and aims: One of the major problems in hospitals is resistant pathogenic bacteria to antimicrobial substances.The problem of increased costs of treatment failure and mortality rates is increasing.The aim of this study was to evaluate the antimicrobial activity of gold nanoparticles has been on Salmonella typhimurium.Methods: This cross-s
