Experimental and design‐oriented research on fiber reinforced concrete segmental tunnel linings: A systematic review

Structural Concrete, Volume 27, Issue 5, Page 6849-6880, October 2026.
Abstract The use of fiber reinforced concrete (FRC) in precast tunnel segments is among the most established and representative applications of this material. Over the past two decades, numerous tunnel linings were constructed with partial or total substitution of conventional steel reinforcement by fibers, this yielding to quantifiable benefits in ...

Anchorage performance of different punching shear reinforcement elements in cracked concrete

Structural Concrete, Volume 27, Issue 5, Page 8225-8243, October 2026.
Abstract Extensive research has been conducted on the bond and anchorage behavior of reinforcement elements in concrete. While many experimental studies have focused on uncracked concrete, the anchorage performance in the presence of cracks remains insufficiently understood.

In situ mixing of organic matter decreases hydraulic conductivity of denitrification walls in sand aquifers [PDF]

, 2008
In a previous study, a denitrification wall was constructed in a sand aquifer using sawdust as the carbon substrate. Ground water bypassed around this sawdust wall due to reduced hydraulic conductivity.

An Optimized Multi‐Stage Drainage Cannula Design for Venoarterial Extracorporeal Membrane Oxygenation

Artificial Organs, Volume 50, Issue 10, Page 1372-1383, October 2026.
This study utilized an extensive optimization involving n = 540 design of experiments to produce a superior drainage cannula design. Compared to the clinically used Maquet model, our optimized design demonstrated reduced blood stagnation volumes, increased cannula tip velocities, and higher upper body drainage, potentially minimizing risk of thrombosis

Uncertainty in the determination of soil hydraulic parameters and its influence on the performance of two hydrological models of different complexity [PDF]

, 2009
Data of soil hydraulic properties forms often a limiting factor in unsaturated zone modelling, especially at the larger scales. Investigations for the hydraulic characterization of soils are time-consuming and costly, and the accuracy of the results ...

Estimation of the hydraulic parameters of unsaturated samples by electrical resistivity tomography [PDF]

, 2012
In situ and laboratory experiments have shown that electrical resistivity tomography (ERT) is an effective tool to image transient phenomena in soils. However, its application in quantifying soil hydraulic parameters has been limited.
