Experiments were carried out to determine the rational range of the proportion of fillers from sand and the dropout of crushing concrete scrap as a replacement part of the cement to obtain colloidal cement glue skirt and to assess the effect of fillers of different specific surface area and the degree of filling on the kinetics of the set of streng

Wireless devices consume large amounts of energy during wireless communication.As the energy storage of battery is limited, improving energy efficiency has become an important approach to prolong the lifetime of devices.The IEEE 802.11 protocol supports the power save mode (PSM) in wireless local area networks (WLANs).However, the standard PSM cann

Humanism is a philosophical view that upholds values and positions of human and make it as a criterion of all things.Humanism has its main object that is human nature, its limits and natural tendencies.Humanism as a term in the intellectual history has always highlighted problems of humanity that is often used in the study of philosophy.Humanism as

Abstract Increased atmospheric CO2 is driving ocean acidification (OA), and potential changes in marine ecosystems.Research shows that both planktonic and benthic communities are affected, but how these changes are linked remains unresolved.Here we show experimentally that decreasing seawater pH (from pH 8.1 to 7.8 and 7.4) leads to reduced biofilm

The current design of member foundation only considers horizontal forces (H) and ignores the effect of torque (T), which may lead to torsional failure of the Cosmetic Sets foundation.To analyze the bearing characteristics of rigid rectangular foundation subjected to horizontal force and torque (H-T), according to the stress characteristics of the f
