Abstract

fetched live from OpenAlex

The capture and re-use of greenhouse irrigation/fertigation water is an efficient use of ever more limited water resources. Although, when capturing and re-applying fertigation solutions there is a greater risk for both pathogen proliferation and chemical contaminant accumulation, both of which can lead to reduced productivity and, in more severe cases, crop loss. In order to avoid these obstacles, it is important that grower’s employ some form of water treatment. Electrochemical disinfection can be used to treat irrigation water by producing and recycling chemical components, in situ, that limit pathogen proliferation while degrading chemical contaminants. Two electrode types (Dimensionally Stable Anodes & Boron-Doped Diamond) using regenerative in situ processes are tested and will be evaluated on their suitability for crop production. Upon analyzing the electrochemical systems’ ability for disinfection and organic pollutant degradation, they appear to be compatible with crop production following preliminary trials.

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 distilled prediction

Teacher imitation

Not 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.
