Estimation Spatial Distribution of Sodium Adsorption Ratio (SAR) and Residual Sodium Carbonate (RSC) in Groundwater of Tando Muhammad Khan Pakistan
Bibliographic record
Abstract
This study was conducted to evaluate factors regulating groundwater quality in an area with agriculture as main use. Water samples for determining the water quality were collected in one liter polyethylene bags by observing standard sample collection method. It was ensured that sample collection sites must be at least 500 feet away from each other.Sodium Adsorption Ratio (SAR) and Residual Sodium Carbonate (RSC) were determined from the collected water and it was observed that in Tando Muhammad Khan taluka, the Sodium Adsorption Ratio (SAR) in the samples ranged from 11.06 to 53.29, the highest (53.29) SAR was in UC Tando Saindad, while lowest (11.06) in the sample collected from UC-2 of Tando Muhammad Khan. The Residual Sodium Carbonate (RSC) in 36 collected groundwater samples ranged from 0.61 to 5.15 meq/l, the highest (5.15 meq/l) was in UC Tando Saindad, while lowest (0.61) in the sample collected from UC-3 of Tando Muhammad Khan.It was concluded that the SAR levels of groundwater samples indicated an alarming situation and most of the ground-water samples had SAR (

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.
