Constitutive Relation with Double Yield Surfaces of Expansive Soil Improved by Lime and Flyash Subjected to Wetting-drying Cycles

工程科学与技术, 2021
The elasto-plastic stress-strain constitutive relation with double yield surfaces of expansive soil improved by lime and flyash was studied based on the ellipse-parabola constitutive model.

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

Effect of Wetting-Drying Cycle on the Deformation and Seepage Behaviors of Rock Masses around a Tunnel

Geofluids, 2020
Water inrush caused by the wetting-drying cycle is a difficult problem in tunnel excavation. To investigate the effect of the wetting-drying cycle on the stability of the tunnel surrounding rock, physical experiments and numerical simulations regarding ...

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 ...

DRYING STRATEGIES CAPABLE OF REDUCING THE STRESS LEVEL OF A STACK OF BOARDS AS DEFINED BY A COMPREHENSIVE DUAL SCALE MODEL

Maderas: Ciencia y Tecnología, 2008
During drying, stresses and deformations develop in a wood board due to shrinkage fields which result from moisture content and temperature field variations.

Simulation and Experimental Studies of Heat-Mass Transfer and Stress–Strain in Carrots During Hot Air Drying

Agriculture
Models were developed to study the heat-mass transfer and stress–strain process in carrots during hot air drying. The distribution and variation in temperature, moisture content, strain, and stress of the samples were investigated at different drying ...

2D model simulating the hydro-rheological behavior of leather during convective drying

Comptes Rendus. Mécanique, 2021
An experimental and numerical study of a two-dimensional spatio-temporal variation of the temperature, moisture content, and mechanical stress during the convective drying process of unsaturated and deformable products (leather) were conducted.

Dimethyl fumarate combined with cisplatin at subcytotoxic doses sensitizes cervical cancer toward ferroptosis and apoptosis through GSH restriction and p53 (re)activation

Molecular Oncology, EarlyView.
Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.
