Bibliographic record
Abstract
RESUMEN: En la actualidad existen diferentes empresas que comercializan aguas envasadas en bolsas plásticas distribuidas en la ciudad de San Miguel, en los últimos años ha generado una preocupación en la población sobre la calidad de este producto. El objetivo del presente estudio de investigación consiste en realizar un estudio de parámetros fisicoquímico y microbiológico, y determinar si estas empresas generan el problema de mala calidad del agua envasada en bolsas plásticas de un aproximado de 5 marcas distribuidas que dominan el mercado de demanda en el área urbana del municipio de San Miguel. La recolección de las muestras se llevará a cabo en cinco diferentes puntos seleccionados. La metodología que se empleara en la presente investigación se considera según su medición y análisis de la información de tipo cuantitativa. De acuerdo con el tiempo de ejecución el tipo de estudio será prospectivo por que la investigación se lleva a cabo a medida su tipo de estudio en el cual se define la población que participa en la observación y dicha población es sujeta a estudio a través del tiempo registrando la información requerida. Dichos resultados se compararán con los límites establecidos en la Norma Salvadoreña Obligatoria de agua envasada. 13.08. Los resultados obtenidos de laboratorio demuestren que el agua que consumen las personas se encuentre entre los límites establecidos en la Norma Salvadoreña Obligatoria de aguas envasadas. \nABSTRACT \nCurrently there are different companies that sell water packaged in plastic bags distributed in the city of San Miguel, in recent years it has generated concern in the population about the quality of this product. The objective of this research study is to carry out a study of physicochemical and microbiological parameters, and determine if these companies generate the problem of poor quality of water packaged in plastic bags of approximately 5 distributed brands that dominate the demand market in the urban area of the municipality of San Miguel. The collection of the samples will be carried out in five different selected points. The methodology that will be used in the present investigation is considered according to its measurement and analysis of quantitative information. According to the execution time, the type of study will be prospective because the research is carried out according to its type of study in which the population that participates in the observation is defined and said population is subject to study over time. recording the required information. These results will be compared with the limits established in the Mandatory Salvadoran Standard for bottled water. 08.13. The results obtained from the laboratory show that the water consumed by people is within the limits established in the Mandatory Salvadoran Standard for bottled water

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.
