The current pandemic of coronavirus disease 2019 (COVID-19) has affected >160 million individuals to date, and caused millions deaths worldwide, at least in part due the unclarified pathophysiology this disease. Identifying underlying molecular mechanisms COVID-19 is critical overcome pandemic. Metabolites mirror progression an individual can provide extensive insights into their pathophysiological significance each stage We a comprehensive view metabolic characterisation sera from...
Abstract The development of a gastric floating‐bioadhesive drug delivery system to increase the efficacy clarithromycin against Helicobacter pylori is described. Floating‐bioadhesive microparticles containing were prepared by combined method emulsification/evaporation and internal/ion gelation for treatment H. infection. Ethylcellulose microspheres (EMs) dispersion clarithromycin, ethylcellulose, chitosan in dichloromethane subsequent solvent evaporation. EMs coated with alginate internal...
Kawasaki disease (KD) is an acquired cardiac with a high incidence that affects children. KD has various complications, including coronary artery dilation (CAD) and aneurysms (CAA). The identification of differentially expressed proteins the underlying mechanisms may be key to understanding differences between these complications. In present study, isobaric tags for relative absolute quantitation were used identify variations in serum patients CAD CAA. total, 87 (37 upregulated 50...
Single-particle aerosol mass spectrometry is a practical method for studying microbial aerosols. However, the related spectral characteristics of single-cell microorganisms have not yet been studied systematically; hence, further investigations are necessary.Different cells were grown and directly aerosolized in laboratory. These aerosols then drawn into single-particle spectrometer platform, spectra profiles obtained real-time. The biological characteristics, ion variation trends, types...
The rapid blocking of DC fault is the bottleneck problem in transmission/distribution technology development. Aiming at problems that high cost and/or losses issue arises with using circuit breaker or modular multilevel converter (MMC) based on improved DC-blocking submodule when clearing faults, an active-current-transferring MMC ability proposed this paper. A current breaking branch, arm branch and energy absorption are introduced to conventional topology. After occurs, actively...
Flexible DC distribution network has flexible control, high power quality and can be equipped with new energy distributed generation, but the serious over-current problem after line fault is one of important factors restricting its development. The analysis calculation short-circuit current great significance for design selection system parameters. However, as MMC converter station a highly complex nonlinear system, exact analytical expression not obtained, so often obtained by simulation....
As an important part of linguistics, definition and development lexical chunks, as well progress various application channels based on Practical Applied Linguistics Pedagogy, is now more valued.Compared with traditional teaching methods, the approach flexible scalable.In current environment, taking a research field zone proximal putting them together can make promising in future.
After the bipolar fault occurs in flexible DC transmission line, converter will affect current, so it is necessary to analyze of system with converter. Aiming at common full bridge MMC topology, this paper establishes its corresponding circuit model after fault, and derives current expressions capacitor discharge stage arm inductance freewheeling blocking. Finally, simulation carried out PSCAD.
Aim at the lack of dc fault handling capability for modular multilevel converter(MMC), A novel ride- through (FRT) control strategy based on virtual motor (VDCM) hybrid MMC, whose arm adopts mixture full- bridge sub-module (FBSM) and HBSM, is proposed in this paper. This adapts AC DC independent which ensures that reactive power voltage support can be provided system during fault. Besides, not only suppress current under pole-to-pole (PTP) fault, enahnces stability to improves when grid...
