Estimates of fluid pressure and tectonic stress in hydrothermal/volcanic areas:a methodological approach

open access: yesAnnals of Geophysics, 2005
An analytical approach to estimate the relative contribution of the fluid pressure and tectonic stress in hydrothermal/ volcanic areas is proposed assuming a Coulomb criterion of failure.

Self-healing in cementitious composite containing bacteria and protective polymers at various temperatures

open access: yesMagazine of Civil Engineering, 2021
Autonomous sealing of cracks in concrete through bacteria-induced calcification has become a topic of great concern in the last two decades. This paper is focused on two main issues of the so-called bio-based self-healing concrete, i.e. protection of the

Quantity Effect of Radial Cracks on the Cracking Propagation Behavior and the Crack Morphology

open access: yesPLoS ONE, 2014
In this letter, the quantity effect of radial cracks on the cracking propagation behavior as well as the circular crack generation on the impacted glass plate within the sandwiched glass sheets are experimentally investigated via high-speed photography system.

Numerical Modeling of Cracked Arch Dams. Effect of Open Joints during the Construction Phase

open access: yesInfrastructures
Running a numerical model for a cracked arch dam that takes into account all the particularities of the materials and dam with a high level of detail has a great computational cost involved. For this reason, it is usual to simplify such a model in search

Discourses and Cracks [PDF]

open access: yes, 2000
This paper discusses information technology as political and practical discourse. This repetitive discursive model can be distinguished in global, regional and local contexts and contains an optimistic belief in technology as an independent power that automatically furthers democratic development.

Infantile Central Nervous System Juvenile Xanthogranuloma With Somatic CSF1R Mutation Responsive to Imatinib Monotherapy

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Juvenile xanthogranuloma (JXG) of the central nervous system (CNS) is a rare non‐Langerhans cell histiocytosis. CSF1R mutations have been reported for peripheral JXG, but not in CNS JXG. A 3‐month‐old male presented with fever, lymphadenopathy, and macrocephaly with bulging fontanelles.
