Behaviour of micropiles in heterogeneous coarse soils [PDF]

, 2016
This paper reports on an experimental investigation on the behaviour of small-diameter piles, commonly referred to as micropiles. This particular type of deep foundation is frequently used in many barely accessible Italian mountainous areas, often ...

Lessons Learned From Using Simple Supervised Learning Tools on Small‐Ensemble Data—Applicability to Tunnel Design and Monitoring

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Integrating interdisciplinary strategies with artificial intelligence (AI), particularly machine learning (ML), is an effective way of addressing urgent engineering challenges. Therefore, a thorough evaluation of existing methodologies is essential, taking into account their respective strengths, limitations and opportunities.

Assessing grout imperfections in prestressed concrete using MWCNTs and temperature-magnetic response techniques

Case Studies in Construction Materials
Unfilled grout inside steel ducts used in prestressed concrete bridges causes corrosion of the steel reinforcement within the grout. This research aimed to detect imperfections in prestressed concrete grout infused with multi-walled carbon nanotubes ...

RC column strengthening by lateral pre-tensioning of FRP [PDF]

, 2003
This paper presents a unique strengthening technique for existing concrete columns that use expansive materials to apply lateral pre-tensioning. The technique increases the capacity and ductility of a column as well as achieving better utilisation of the

The Curious Case of CysE: Diversity and Distribution of Serine Acetyltransferases in Bacteria

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Serine acetyltransferase (CysE) is a member of the left‐handed β‐helix family of acetyltransferases that catalyze the rate limiting step in de novo cysteine biosynthesis. There are two isoforms of CysE that differ in length, with the shorter isoform lacking approximately 76 amino acids at the N‐terminus of the protein from the serine ...

Evaluation of prestress losses in concrete beams using destructive and non‐destructive methods

Structural Concrete, EarlyView.
Abstract Over the past few decades, prestressing techniques have become essential in the construction of key structures, infrastructure, and bridges. The serviceability and safety of prestressed concrete (PC) elements are closely tied to the effectiveness of the prestressing process.
