Abstract
The experiments were conducted to study of the acute toxicity of Cyprinus carpio and Rutilus rutilus by added copper salt in basins. 13 fishes with average weight of 2±0.5g to Rutilus rutilus and 20±2.2g Cyprinus carpio were exposed to different concentrations of copper salt respectively. The experiments were done by Static Method during 96 hours. A group of fish was considered as control samples. The different concentrations of copper such as 0, 0.1, and 0.2, 0.3, 0.4, 0.45 and 5mgL-1 were used to Rutilus rutilus and Cyprinus carpio fishes. Under stable condition (TOC and pH), the lethal concentration of copper was measured of 0.4mgL-1 and 0.45mgL-1 to Rutilus rutilus and Cyprinus carpio respectively during of 96 hours. The results indicated the significant differences were observed between treatments of fish with each other and also with the control samples. With increasing of copper in each treatment, the mortality rate of fish significantly was increased. Histopathological findings showed that major lesions were hemorrhage, hyperemia, hyperplasia and epithelial cells necrosis in total fish. Also in the lesion fish were observed degenerated tubules of their kidney, expansion of Bowman's capsule and hepatocytes necrosis.

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
