Abstract

fetched live from OpenAlex

Forest harvesting residues are potentially a vast source of feedstock for bio-based energy facilities. However, the high moisture content of the residues lowers the energy density and adversely impacts the efficiency of transportation. Inorganic and ash contents of forest harvesting residues could also reduce the efficiency of combustion processes and cause fouling, slagging, and corrosion in forest residue-burning apparatuses. The main objective of this research was to conduct measurements to monitor moisture, ash, and inorganic (Ca, K, Mg) contents of forest harvesting residues throughout the year. This would help to decide the optimum size of the residue, height and orientation of the residue pile, as well as the optimum season (that is, when those contents are at their lowest) to remove the residues from the forest to biomass-based facilities. Samples of aspen and pine residues, together with temperature, humidity, and precipitation measurements, were taken bi-weekly in two sites at Cynthia and Drayton Valley, Alberta, Canada, from early spring to early fall, and analyzed for two successive years. The results suggest mainly small-size residues should be stored in toll piles until late September and the piles of such residues should be oriented southward before removing them from the forest.

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.
