Experimental Investigation on the Effects of Audible Sound to the Growth of Aspergillus Spp
Bibliographic record
Abstract
This paper discusses the effect of sound on the growth of fungus, Aspergillus spp. Aspergillus was cultured on Potato Dextrose Agar (PDA) and Potato Dextrose Broth (PDB) and exposed to sound waves for five hours per day for three days. This experiment was observed for three days and data were recorded everyday after the exposure. Four parameters were used to measure the growth of fungus which were colony forming units per ml, optical density, length of germ tube and the diameter of the colony. The results showed that sound waves have effects on the growth of Aspergillus. When Aspergillus was exposed to sound waves with frequencies of 5 kHz, 10 kHz and 15 kHz, the growth was affected by the different frequency. The higher the frequency, the higher the growth inhibition found on Aspergillus. All the three frequencies inhibited the growth of Aspergillus compared to the control (No exposure to sound) and the maximum inhibition occurred at the frequency of 15 kHz.

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.
