Experimental study on the effect of operating parameters on the mass transfer ability of Hangang 250 t converter

open access: yes工程科学学报, 2016
The mass transfer rate between steel and slag determines the reaction rates of elements in a molten bath(especially the reaction rates of desulphurization and dephosphorization),and has direct impact on the distribution ratios of elements between steel ...

Rab14 regulates the transport of human papillomavirus to the trans‐Golgi network for infectious cell entry

open access: yesFEBS Letters, EarlyView.
This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.

A New Single-Stage Three-Phase PFC for Four-Switch Three-Phase Inverter Fed IM Drives

open access: yesAdvances in Electrical and Computer Engineering, 2019
This paper proposes a single-stage three-phase power factor correction (PFC) for four-switch inverter (FSI) fed induction motor (IM) drives. The PFC scheme uses a Cuk converter with only one switch, and consequently, it needs only one control signal ...

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Electron transfer between complexes III and IV in S. cerevisiae mitochondrial membranes

open access: yesFEBS Letters, EarlyView.
Mitochondrial oxidative phosphorylation in S. cerevisiae mitoplasts is limited by complex IV catalytic capacity, rather than two‐dimensional cytochrome c diffusion. At physiological cytochrome c : supercomplex ratios at salinity equivalent to that of 20 mm monovalent salt, activity is maximized, indicating that this low ionic strength accurately mimics

A Proposal of a Novel Method for Generating Discrete Analog Uniform Noise

open access: yesAdvances in Electrical and Computer Engineering, 2018
This paper presents a proposal of a new way to generate analog noise, discrete in time, with uniform probability density function. Instead of the usual way of generating discrete analog uniform noise using a uniform pseudorandom number generator and a ...
