Efficacy of UV irradiation on eight species of <i>Bacillus</i>
Bibliographic record
Abstract
Ultraviolet irradiation has commonly been used in the indoor environment to eliminate or control infectious diseases such as tuberculosis in medical care facilities. Heating, ventilating, and air-conditioning (HVAC) system components such as duct-liners, cooling coils, drip-pans, interior insulation, and areas subjected to high levels of moisture can create an environment that is prone to biological contamination. Air supplied to indoor environments can carry biological contaminants that can expose numerous building occupants to pathogenic organisms. Possible terrorist activities could release biological agents into ambient air, or directly into a building environment, or HVAC system may expose multitudes of individuals to dangerous pathogens. The use of germicidal ultraviolet lamps (UVGI) in commercial and residential HVAC systems has increased. A method to determine the antimicrobial efficacy of UVGI irradiation was developed and tested on the surface of agar plates with eight varieties of Bacillus bacteria spores. Bacillus anthracis surrogates were used for their expected similar inactivation responses to UVGI irradiation. The percent kill and k value for each organism was calculated for various periods of exposure.Key words: antimicrobial, germicidal, antimicrobial efficacy, HVAC, biocontaminant.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
