The adsorption mechanism of the removal of lead from water by using jmannino.com carboxylic functional group (COOH) functionalized on the surface of carbon nanotubes was investigated.Four independent variables including pH, CNTs dosage, contact time, and agitation speed were carried out to determine the influence of these parameters on the adsorpti

The next frontier of maritime networking will see the deployment of large-scale buoy-based mesh networks, with an equal emphasis on both high-speed data transfer and energy-efficiency.One such challenging application is the operation of maritime seismic surveys for oil/gas exploration and academic studies.Large amounts of seismic data are generated

Knowledge is one of the key resources in business development.Framework for the analysis of the knowledge management system may be built around the concepts of: properties of units, properties of relationships between the gel bottle cashmere units, and properties of knowledge.Effective knowledge management results from providing individuals with th

Energy-efficient communications, namely, green communications, has attracted increasing attention due to energy shortage and greenhouse effect.Motivated by this, we consider the uplink energy-efficient resource allocation in multiuser massive multiple-input multiple-output (MIMO) systems.Specifically, we consider that both the number of antenna arr
