Numerical model for prediction of corrosion of steel reinforcements in reinforced concrete structures

open access: yesUnderground Space, 2019
Reinforced concrete structures experience alteration and degradation during their lifetime due to the corrosion of the steel reinforcements. Prevention of the steel corrosion is indispensable to avoid structural degradation.

Changes in land‐snail communities and steppe environments in the lower Rhône valley during the Lateglacial–Holocene transition

open access: yesBoreas, EarlyView.
Land snail successions in the lower Rhône valley allow us to reconstruct the postglacial recolonization. From the Lateglacial period onwards, Mediterranean steppe communities appeared. The arrival of forest taxa was significantly delayed by aridity. The question of glacial refugia, both local and distant, primarily concerned Mediterranean species of ...

Spatial Variation of Acidic Sodic Soils in High‐Andean Environments and Theoretical Estimation of Gypsum Requirement

open access: yesSoil Use and Management, Volume 42, Issue 3, July‐September 2026.
ABSTRACT High‐Andean forage systems are characterized by extensive management of cultivated forages, primarily through rotation of forage oats (Avena sativa) and alfalfa (Medicago sativa), under marginal edaphoclimatic conditions. Within this context, soil sodicity severely constrains the productivity of these systems in the districts of Ayaviri and ...

“Flames Over Persepolis”: New Scientific Evidence Supporting Historical Perspectives

open access: yesArchaeometry, Volume 68, Issue 3, Page 421-433, June 2026.
ABSTRACT This study investigates the burning of Persepolis Terrace, historically attributed to Alexander III in 330 bce. A review of classical accounts and excavation reports, combined with diagnostic surveys, confirms the fire's historicity and provides novel insights.

Integrated sensor network for monitoring steel corrosion in concrete structures

open access: yesVitruvio: International Journal of Architectural Technology and Sustainability, 2016
Corrosion is one of the main triggering factors affecting the service life and durability of structures. Several methods are used for corrosion studies but electrochemical techniques are the most commonly applied.

Quantitative X‐Ray Fluorescence Imaging to Evaluate the Efficacy of Micro‐Structured Cellulose Foams and Poultices in Wall Painting Desalination

open access: yesChemistry–Methods, Volume 6, Issue 1, January 2026.
This work assesses, through a quantitative micro energy dispersive X‐ray fluorescence imaging, the effective use of micro‐structured cellulose foams as a sustainable alternative to traditional poultices for desalinating fresco paintings. Foams were between 6 and 10 times more efficient, achieving rapid and in‐depth salt removal with reusability and ...

APPROCHE DE PERFORMANCE POUR LA DURABILITE DES BETONS EXPOSES A LA CARBONATATION [PDF]

open access: yes, 2012
La carbonatation est un phénomène de vieillissement naturel qui concerne tous les bétons. Une de ses principales conséquences est de favoriser la corrosion des armatures en les dépassivant. Ce phénomène mérite donc d’être examiné afin de mieux comprendre
