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

FEBS 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 ...

Improving the laser powder bed fusion processability of A2618 alloy: Investigation on TiB2 addition strategies via single scan track approach

Journal of Materials Research and Technology
Processing aluminum alloys by Laser Powder Bed Fusion (L-PBF) is of great interest for components production in various industries; however, their processability is quite challenging due to their susceptibility to solidification cracking.

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

FEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Processability Theory applied to written and spoken L2 Swedish

, 2006
This study investigates grammatical development in foreign and second language learners of Swedish. The hypothesis is that the hierarchy of processability predicted by Processability Theory (Pienemann 1998) guides both written and spoken learner ...

Investigate the Processability of Biobased Thermoplastics Used in Nonwoven Fabrics [PDF]

The Covid-19 pandemic increased enormously the manufacturing and usage of face masks and other personal protective equipment (PPE), resulting in accumulation of plastic waste and, thus, causing universal environmental concerns. In addressing the issue of

Machine-Learning Integration of Geophysical Responses for Predicting Metallurgical and Environmental Indicators in Mineral Systems

UMYU Scientifica Journal
The sustainability of mineral development increasingly depends on early understanding of ore processability and environmental behavior rather than ore grade alone.

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

FEBS 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

On Processability of Lemke’s Algorithm

, 2018
Lemke’s algorithm is a pivotal kind of algorithm which is developed based on principal pivot transform. We consider several matrix classes to study the relationship among them in the context of linear complementarity problem.
