Impact of Successive Wetting and Drying Cycles on Some Physical Properties of Gypsifereous Soils
Bibliographic record
Abstract
A laboratory experiment was carried out to quantify the impact of three wetting-drying cycles onphysical and mechanical properties of gypsifereous soils such as bulk density, penetration resistance, drying index, shrinkage limit and pore geometry changes.The soil gypsum content treatments were 60.0 (G 1 ), 137.6 (G 2 ), 275.2 (G 3 ), 314.2 (G 4 ), 486.0 (G 5 ), 688.3 (G 6 ) and 860.0 (G 7 ) g.kg -1 . Soil samples were equilibrated to a matric potential -4.9, -9.8, -34 and -1500 kPa after saturation for each wetting-drying cycle. Peak cone index values showed that besides water content and bulk density, penetration resistance was positively affected by gypsum content. Drying index values at 1200 kPa matric potential were increased from 79.96% to 96.50% for the soils with gypsum content G 1 to G 7 .

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
