Abstract

fetched live from OpenAlex

La culture du palmier dattier constitue sans aucun doute une participation importante sur le plan socio-economique dans l’agriculture saharienne surtout dans la wilaya de Biskra. En effet, le palmier procure, grâce a la commercialisation aux echelles nationale et internationale de son fruit, un revenu regulier pour les phoeniciculteurs et constitue une deuxieme source de devise apres les hydrocarbures. Il represente la principale ressource de vie des populations de ces regions et offre des emplois directs et indirects. Au cours de la derniere decennie, la productivite des palmiers dattiers a decline dans les zones de cultures traditionnelles. Ce sont 30 % de la production qui peuvent etre perdus sous l'effet des maladies et des parasites tels que : El Boufraoua due a une cochenille blanche. La poussiere est consideree comme l’un des plus importants facteurs contribuant a la propagation de cette maladie. Dans ce travail, les impacts de la dispersion des poussieres produites par trois carrieres doivent etre caracterises et simules a l’aide d’un logiciel de simulation de type CFD en utilisant le model Eulerien. Les resultats de la simulation obtenus montrent bien le depot de la poussiere qui est a l’origine de la parution de la maladie sus- citee emanant de ces trois carrieres sur les palmiers dattiers et meme sur les habitants du village d’El-Hadjeb aux environs de Biskra.

Not 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.
