Abstract

fetched live from OpenAlex

Este trabajo tuvo como fin determinar cantidad de carbono asimilado en arboles de la especie Tectona grandis mediante el analisis densitometrico. La muestra consistio en cinco discos extraidos de cinco individuos de esta especie procedentes del Fundo La Genova (Chanchamayo). Estos discos fueron utilizados para hallar las areas pertenecientes a sus anillos y se prepararon muestras para realizar un ensayo de densitometria de rayos X. La biomasa de carbono fue hallada relacionando el area del anillo con los valores de densidad obtenidos. Como conclusion se determino la efectividad del metodo utilizado para la determinacion de la biomasa de carbono en los anillos de crecimiento para la especie Tectona grandis. A su vez, se pudo observar una diferencia significativa de carbono secuestrado entre los 5 arboles evaluados. Se encontraron menores concentraciones de carbono en los anillos pertenecientes a la fase juvenil.

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.

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.
