Abstract

fetched live from OpenAlex

Poly Vinyl Alcohol (PVA) films were prepared using solution casting. The Tensile Strength (TS), Tensile Modulus (TM) and Elongation at break (Eb) of the prepared films were found to be 23.58 MPa, 32 MPa and 302% respectively. Moisture content and water uptake analysis were also checked. Then, gelatin and nano crystalline cellulose (NCC) were incorporated into PVA film and again physchio-mechanical properties were measured. The TS, TM and Eb values of PVA/Gelatin-based films were 23.57 MPa, 114.58 MPa, 48.10% respectively. On the other hand, PVA/Gelatin/NCC-based films showed the TS, TM, and Eb values of 32.92 MPa, 129.8 MPa, 58.5% respectively. Thermal degradation test was accomplished by Thermo-Gravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC). Spectroscopic analysis was also done by Fourier Transfer Infra-Red (FTIR). The soil degradation test confirmed the inherent biodegradable nature of the films. The prepared bio-polymeric films were exposed to gamma radiation. It was found that at 6 kGy dose the mechanical properties of the films improved significantly.

Not 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.
