In Vitro Effects of External Pressure Changes on the Sealing Ability under Simulated Diving Conditions

International Scholarly Research Notices, Volume 2012, Issue 1, 2012., 2012
Aim. To measure and validate the permeability of pressure changes in correlation to different root filling techniques. Methods. Eighty extracted single‐rooted teeth were randomly assigned to one of eight groups of ten teeth. Following standardized instrumentation and irrigation, root canal fillings were performed using either cold lateral condensation,

Quantification of Degradation Rate Constants in Aquifer Materials Using Carbon‐14 Chlorinated Ethenes

Groundwater Monitoring &Remediation, Volume 45, Issue 4, Page 101-112, Fall 2025.
Abstract Among the most challenging sites to remediate are those where the groundwater is contaminated with large, dilute plumes of tetrachloroethene (PCE), trichloroethene (TCE), cis‐1,2‐dichloroethene (cDCE), and vinyl chloride (VC). Monitored natural attenuation (MNA) may be a viable strategy, but relevant mechanisms such as abiotic degradation can ...

Small strain shear modulus of saturated and unsaturated cohesive soils under anisotropic consolidation

Soils and Foundations
Cohesive soils in nature are created under anisotropic stress and have various stress histories. Embankments generate greater vertical loads underground. Moreover, associated excavation activities can exacerbate the extensional stress state.

In‐Stream Nitrogen Dynamics in a Point Source Influenced Headwater Stream During Baseflow Conditions

Water Resources Research, Volume 60, Issue 9, September 2024.
Abstract Hydrochemical signatures are often traced back to their original sources using data collected at catchment outlets. However, this approach introduces uncertainties, as signals may add up, cancel each other out, or be subject to transformation processes. Specifically rural point sources, such as communal wastewater treatment plants (WWTPs), are

BiFormer Attention‐Guided Multiscale Fusion Mask2former Networks for Fish Abnormal Behavior Recognition and Segmentation

Aquaculture Research, Volume 2024, Issue 1, 2024.
To address the issues of accurately identifying and tracking individual fish abnormal behaviors and poor adaptability in the aquaculture field, this paper proposes a Mask2former model combined with a bidirectional routing attention mechanism (BiFormer) and a multiscale dilated attention (MSDA) module for fish abnormal behavior recognition and ...
