Abstract
Gu, D., Sokhansanj, S. and Haghighi, K. 2000. Influence offloor air entry on grain moisture content, temperature, and bulk shrinkage during ambient air in-bin drying of wheat. Can. Agric. Eng. 42:185-193. Wheat at 22% m.c. (w.b.) was dried using ambient air in an experimental bin with a fully perforated, a partially perforated, or a slanted perforated floor. When grain was dried in the bin with a partially perforated floor, moisture contents of the grain were distributed in such a way that higher moisture content grain was at the sides of the bin. When grain was dried in the bin with a slanted perforated floor, grain at the center ofthe bin remained wet throughout the drying process. Profiles of inter-granular temperature contours were similar to profiles of moisture content contours. Higher temperatures corresponded to lower moisture contents. Inter-granular air temperature remained at or near the wet-bulb temperature of the drying air until the grain moisture content decreased to 15% (w. b.). A curved grain surface resulted from uneven bulk grain shrinkage due to non-uniform airflow. At the same plenum static pressure and with the same volume of grain, air entering the bin with a partially perforated floor was about 78% of that with a fully perforated floor. Keywords: drying, shrinkage, airflow, moisture content, temperature, ambient air, floor, wheat. Du ble dont Ie taux d'humidite etait de 22% (base humide) fut seche en utilisant l'air ambiant dans des silos experimentaux ayant un plancher entierement perfore, un planeher partiellement perfore, et un plancher perfore incline. Apres Ie sechage du grain dans Ie silo a planeher partiellement perfore, les grains qui etaient places sur les cotes du silo avaient la teneur en eau la plus elevee. Lors du sechage dans Ie silo a plancher perfore incline, Ie grain au centre du silo est demeure humide tout au long de la periode de sechage. Les courbes de temperature entre les grains suivaient les courbes de teneur en eau des grains. Les temperatures plus elevees correspondaient a des teneurs en eau plus faibles et vice versa. La temperature de l'air entre les grains est demeuree pres de ou ala temperature boule humide de l'air utilise pour Ie sechage, jusqu'a ce que la teneur en eau du grain s'abaisse a 15 % (b.h.). Les grains avaient une surface courbe parce que, comme la circulation de I' air n'etait pas uniforme, la masse de grains s'est contractee de maniere inegale. Pour un meme volume de grain et pour une pression statique identique dans la chambre de distribution, la quantite d'air penetrant dans Ie silo a travers Ie plancher partiellement perfore representait 78% de la quantite d'air penetrant dans Ie silo par un plancher entierement perfore. Mots cles: sechage, contraction, ecoulement d'air, teneur en eau, temperature, plancher, ble.

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 it
