Mise au point d’une suspension bactérienne épaissie pour l’exobiocicatrisation de matériaux cimentaires fissurés
Bibliographic record
Abstract
La précipitation de carbonate de calcium par les bactéries offre la possibilité de réparer les matériaux cimentaires fissurés par une méthode durable et non polluante. Une suspension bactérienne épaissie a été mise au point pour favoriser la biocicatrisation de microfissures entre 150 et 500 μm en utilisant la souche bactérienne Bacillus pseudofirmus. Le fluide obtenu, par synergie entre deux épaississants colloïdaux, est fortement rhéofluidifiant et thixotrope, résistant à la décantation et forme lors d’un repos prolongé un gel physique réversible. Ces propriétés permettent de l’injecter sans drainage post-injection dans des fissures d’ouverture variant de 150 à 500 μm. L’ajout d’épaississants n’a pas d’impact sur la croissance ni sur l’activité de B. pseudofirmus et entraîne la formation d’amas autour des bactéries. Cette structure similaire à un biofilm favorise potentiellement leur survie face aux contraintes du milieu extérieur.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
