Under the repeated action of traffic and thermal loads, a cement concrete pavement slab may partially lose contact with its base course, and voids may develop underneath the slab.Such distress will greatly impact the pavement performance.To fill the voids and restore the base support to the slab, the technology of polymer grouting has been increasi
Integration of deep transcriptome and proteome analyses reveals the components of alkaloid metabolism in opium poppy cell cultures
Abstract Background Papaver somniferum (opium poppy) is the source for several pharmaceutical benzylisoquinoline alkaloids including morphine, the codeine and sanguinarine.In response to treatment with a fungal elicitor, the biosynthesis and accumulation of sanguinarine is induced along with other plant defense responses in opium poppy cell culture
Heterogeneous catalytic carboxylation of terminal alkynes with CO2 over a copper(II)-based metal-organic framework catalyst
Developing efficient, inexpensive and robust heterogeneous catalysts for CO2 conversion is greatly important.In this study, a new stable copper(II)-based metal-organic framework [Cu(Fbtx)2Br2]n (denoted as CZU-7, CCDC-2165700, Fbtx = 1,4-bis(1,2,4-triazole-1-ylmethyl)-2,3,5,6-tetrafluorobenzene) was synthesized via a facile and fast microwave Keych
Sensory information and encounter rates of interacting species.
Most motile organisms use sensory cues when searching for resources, mates, or prey.The searcher measures sensory data and adjusts its search behavior based on those data.Yet, classical models of species encounter rates assume that searchers move independently of their targets.This assumption leads to the familiar mass action-like encounter rate ki
