Reduction of economic efficiency of marine diesel from pollution of elements and turbocharger cavity when using fuels of different composition [PDF]

Омский научный вестник, 2019
The detailed analysis of pollution of details and cavities of a gas turbocharger (GTN) of a ship diesel engine is done. The composition of contaminants and their impact on the operating conditions of the diesel engine is revealed, and an approximate ...

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

Biofuel scenarios in a water perspective: the global blue and green water footprint of road transport in 2030 [PDF]

, 2010
The trend towards substitution of conventional transport fuels by biofuels requires additional water. The EU aims In the last two centuries, fossil fuels have been our major source of energy.

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

Water transport controversies – an overview [PDF]

The Journal of Physiology, 2002
The last 20 years have seen major advances in the understanding of the mechanisms and molecular bases of water transport across cell membranes. Prominent among these advances was the discovery of a family of transmembrane proteins that permeate exclusively or dominantly water (aquaporins), followed by structural studies identifying the intramolecular ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Regulation of NH₃-SCR Reaction Pathway over MnO_x/TiO₂ Catalyst by WO_x Promotion and the Synergistic Enhancement Effect of VO_x

Crystals
Effective abatement of nitrogen oxides (NOx) is achieved by ammonia selective catalytic reduction (NH3-SCR). In this paper, the effects of single WO3 doping and WOx-VOx co-doping into the MnOx/TiO2 catalyst on NH3-SCR of NOx removal, sulfur and water ...
