Abstract
Vegetable oils have fuel properties that are not compatible with the requirements for use as diesel engine fuel, the common method of properties modification is by transesterification which involves stripping glycerines from the triglycerides. To determine the effects of transesterification, 5 properties were selected and their values were measured before and after transesterification. The fatty acid profile of the vegetable oils was also measured by a chromatography analyzer to determine the impact of fatty acids composition. The results obtained shows that for example, density reduces by 7 to 9% while cetane number increased by 60 to 78%. Transesterification tends to make the properties of vegetable oils close to those of diesel. Key words: Transesterification, fatty acids, fuel properties, castor oil, pumpkin oil, groundnut oil.

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 it
