An Analytical Method of Coulomb’s Active Earth Pressure Acting on Cohesion-Less Backfill Subject to Local Surcharge in Cold Regions

Advances in Civil Engineering, 2020
The traditional Coulomb’s earth pressure theory does not consider the effect of local surcharge on the lateral earth pressure and its critical failure angle.

Numerical study of the deformation behavior of back-to-back MSE walls under dynamic loading [PDF]

E3S Web of Conferences
Back-to-back mechanical stabilized earth (MSE) walls are commonly used for embankments, ramps, and bridge approaches. The deformation behavior of back-to-back MSE walls is significantly influenced by the geometrical configuration, especially the width to

Prediction of the Liquid Vapor Pressure Using the Artificial Neural Network-Group Contribution Method [PDF]

Iranian Journal of Chemistry & Chemical Engineering, 2015
In this paper, vapor pressure for pure compounds is estimated using the Artificial Neural Networks and a simple Group Contribution Method (ANN–GCM). For model comprehensiveness, materials were chosen from various families.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

The significance of intra-abdominal pressure on postural stabilization: A low back pain case report

Slovak Journal of Sport Science, 2022
Intra-abdominal pressure is a hydraulic pressure within the abdominal cavity. Previous studies confirmed its direct association with both spinal stability and spinal unloading.

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

FEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

The Effect of Manipulation and Mobilisation on Pressure Pain Thresholds in the Thoracic Spine [PDF]

, 2004
High velocity low amplitude (HVLA) thrust manipulation and mobilisation are commonly used by manual therapists to relieve spinal pain and improve mobility. The aim of this controlled, single blinded study was to investigate the effect of manipulation and

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

The Size Effect on Critical Back Pressure Ratio for Sonic Nozzles [PDF]

, 2020
As an important parameter, the critical back pressure ratio is directly related with the application of sonic nozzle. When the stagnation condition was fixed, the size effect on critical back pressure ratio was investigated.

Numerical investigation of the flow characteristics inside a supersonic vapor ejector

International Journal of Thermofluids
Integrating a vapor ejector with an air-cooled absorption cooling system (ACS) requires understanding how the ejector responds to varying condenser conditions and how the geometrical parameters affect the system's performance.
