In-Season Physiological and Biochemical Status of Reforestation Workers
Bibliographic record
Abstract
Tree-planting demands sustained high work-output and is associated with high injury rates but has not been characterized previously. Data were collected from 10 male planters after 19 +/- 5 (T1) and 37 +/- 5 days (T2) of planting. One severe infection and one knee strain injury were noted. Loads carried were 32% +/- 5% body mass and heart rates were between 60% to 75% of maximum for 57% +/- 26% of the planting shift. A loss of 1.7% +/- 1.5% body mass occurred, although intake exceeded 5000 kcal/day. From 8% (T1) to 27% (T2) of postprandial blood glucose samples were found to be < 3.3 mmol/L. Further evidence of the cumulative stress was seen in increased levels of resting cortisol (428 +/- 163 to 741 +/- 103 mmol/L), norepinephrine (2.09 +/- 1.34 to 3.09 +/- 1.05 mmol/L), and creatine kinase (184 +/- 82 to 397 +/- 174 U/L) at T2. The postactivity neutrophilia and lymphophilia (absolute count, CD4+ and CD8+) observed at T1 were blunted at T2. The implications of mild hypoglycemia, including possible effects on cognitive and motor function, warrant further study.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
