On a shallow water model for the simulation of turbidity currents [PDF]

, 2009
We present a model for hyperpycnal plumes or turbidity currents that takes into account the interaction between the turbidity current and the bottom, considering deposition and erosion effects as well as solid transport of particles at the bed load due ...

A Mini‐Spidroin Forms High‐Performance Artificial Spider Silk via Edge‐Cysteine–Locked β‐Sheet Assembly

Advanced Science, EarlyView.
Cysteine‐engineered mini‐spidroins (∼33 kDa) undergo phosphate‐induced liquid–liquid phase separation (LLPS), where disulfide bonds lock partially aligned polyA segments. Subsequent microfluidic spinning promotes directional β‐sheet crystallization, producing fibers with 531 MPa strength and 182 MJ/m3 toughness.

Laboratory investigation of the effect of thickness and two porous obstacles with a spacing in the Control the Turbidity Current [PDF]

مهندسی منابع آب, 2020
In the present study, a laboratory comparison of increasing the number of porous obstacle rows and two porous obstacles with a distance of one meter is considered as a permeable obstacle for controlling turbidity current in different heights.

H2S‐Releasing Aspirin Nanoparticles Alleviate Endometriosis and Associated Anxiety

Advanced Science, EarlyView.
Albumin nanoparticles loaded with an H2S‐releasing aspirin derivative (ACS14) hitchhiking neutrophils after intraperitoneal injection and preferentially accumulate in endometriosis lesions in mice. The treatment suppresses lesion growth by regulating PI3K/Akt and reduces inflammation by inhibiting NF‐κB.

Reimagining o‐Carborane‐Based Fluorophores: Charge‐Transfer from Boron Substituents Triggers Aggregation‐ and Crystallization‐Induced Emission

Angewandte Chemie, EarlyView.
This work reports, for the first time, aggregation‐ or crystallization‐induced emission in boron‐substituted carboranes, which was driven by photoinduced charge‐transfer from fluorophore attached via boron vertices. The emission properties can be tuned by varying the substituents, expanding design strategies for luminescent materials.

Quantifying measures to limit wind driven resuspension of sediments for improvement of the ecological quality in some shallow Dutch lakes [PDF]

, 2012
Although phosphorus loadings are considered the main pressure for most shallow lakes, wind-driven resuspension can cause additional problems for these aquatic ecosystems. We quantified the potential effectiveness of measures to reduce the contribution of

Structural Basis of the Membrane Association by the Conserved RocS Membrane‐Targeting Sequence in Streptococcus

Advanced Science, EarlyView.
Chromosome segregation in Streptococcus pneumoniae depends on RocS, a bitopic protein whose membrane‐anchoring mechanisms were unclear. Using NMR and AFM, this study reveals that the widely conserved RocS anchor binds to membranes via a conserved kink‐helix motif which inserts into lipid nanodomains.
