The complete nucleotide sequence of the genome of wheat Eqlid mosaic virus (WEqMV) (excluding the poly A tail) comprised 9636 nucleotides including 5' and 3' noncoding regions of 137 and 172 nt, respectively. It contained a single ORF coding for a polyprotein of 3,109 amino acid residues and had a deduced genome organization typical of members of the family Potyviridae and with proteinase cleavage sites very similar to those of the members of the genus Tritimovirus. Pairwise and multiple alignments and phylogenetic analysis showed that WEqMV is a distinct species in the genus Tritimovirus. WEqMV and Wheat streak mosaic virus (WSMV) shared the greatest nucleotide sequence identity in the NIb and HC-Pro cistrons (63.2% and 60.8%, respectively) and the lowest sequence identity in the P1 and CP cistrons (51.2% and 51.1%, respectively). Sequence identity for the complete genome of WEqMV and WSMV was 56.8% at the nucleotide level and 50.7% at the amino acid level. WEqMV had 57.2% nucleotide identity and 50.6% amino acid identity with Oat necrotic mottle virus and 52.5% nucleotide identity and 45.5% amino acid identity with Brome streak mosaic virus. The relationship of WEqMV with other members of the family Potyviridae was more distant. Structural analysis of WEqMV protein showed presence of potential transmembrane helices in 6k1, 6k2, and P3 proteins.
Today, CO2 separation is very important, both as an environmental issue and also in various industries. In this study, the water‐based nanofluid of NaP zeolite nanocrystals and 1‐dodecyl‐3‐methylimidazolium chloride ([C12mim][Cl]) ionic liquid were mixed and tested experimentally for CO2 absorption in an isothermal high pressure cell equipped with magnetic stirring. Zeolite nanocrystals were synthesized via the hydrothermal approach and characterized. A series of experiments were performed at different conditions to investigate the impact of various parameters, including nanoparticle type, nanoparticle concentration, stabilizer concentration, and the vessel's initial pressure, on CO2 solubility. It was found that 0.02 wt.% of zeolite nanoparticles, 0.4 wt.% of [C12mim][Cl] ionic liquid, and 0.05 wt.% of sodium dodecyl benzene sulphonate (SDBS) in nanofluids result in higher absorption of CO2 compared to other concentrations. Furthermore, CO2 absorption was increased by increasing ionic liquid and surfactant concentration up to a certain value near critical micelle concentration, but after that the CO2 absorption was decreased. The overall CO2 absorption enhancement at 20 bar for 0.02 wt.% zeolite and ZnO water‐based nanofluids with 0.4% [C12mim][Cl] ionic liquid and 0.02 wt.% SDBS were 26.9%, 21.5%, 21.2%, and 17% in comparison to pure water, respectively. In an absorption process using nanofluids, besides the influence of the mentioned parameters, the micro‐convection caused by Brownian motion and the grazing effect of nanoparticles should be noted. Considering the micro‐convection and grazing effects, a theoretical model should take into account the Brownian motion and grazing effects on the mass transfer rate in nanofluids to investigate the absorption enhancement by nano‐particles.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
