In the present research, mass transfer resistances of various steps of uranium biosorption using Pseudomonas putida @ Chitosan biosorbent in a fixed bed column were calculated.The description process dynamic parameters using dimensionless numbers showed that the Biot number was greater than 30 in all experiments which confirms the high mass transfe
Problem and goal.In terms of informatization of school education, the use of information technology in teaching students any discipline, obviously, should be correct, justified.The article discusses the methodological aspects of the use of information technology in didactic games in computer science lessons in the lower grades.Methodology.The Feder
In this work, magnetic CuFe2O4/Ag nanoparticles activated by porous covalent organic frameworks (COF) was fabricated to evaluate the heterogenous reduction of 4-nitrophenol (4-NP).The core-shell CuFe2O4/Ag@COF was successfully prepared by polydopamine reduction of silver ions on CuFe2O4 nanoparticles, followed by COF layer condensation.By integrati
The title compound, C20H18N2O4, is a chalcone derivative of Antacids pyrazole.The pyrazole ring is inclined at a dihedral angle of 19.29 (12)° to the methoxyphenyl ring mean plane, and by 1.19 (13)° to the phenyl ring.The molecular structure is Bottle Stopper stabilized by an intramolecular O—H.O hydr
Triticale var.Lasko embryos, isolated from grain gathered at milk ripeness, the beginning of wax ripeness and at full ripeness, were allowed to germinate for 48 h on agar with glucose.The highest incorporation of tritiated adenosine into polyribosomal RNA during germination was found in the ribosome fractions from embryos of grain gathered at full
