ENVIRONMENTAL POLLUTION OF THE CASPIAN REGION OF AZERBAIJAN
Bibliographic record
Abstract
EPR and low-temperature photolysis methods have been used to study the processes of phototransformation in oil systems under the influence of solar radiation and photosensitizers: polycyclic aromatic hydrocarbons, asphaltenes, resins.It is shown that in organic compounds (alcohols and paraffins) with the addition of a photosensitizer Sh1 (C=10 -7 mol/l) to their solution, alcohol, alkyl radicals and atomic hydrogen R • are formed under the influence of full light from a mercury lamp DRSh-500, which reacts with hydrocarbons to form molecular hydrogen (H2), easily reacting with oxygen O2 , form peroxide radicals R • O2 , then the process proceeds by the mechanism of a chain reaction.It has been established that in the presence of izo-compounds in oil, radicals of substituted aromatic hydrocarbons are formed in them under the influence of solar radiation.It is shown that methylperinaphthene radicals with photochromic properties are registered in the products of secondary oil refining (cracking, pyrolysis).The kinetic patterns of the generation of methylperinaphthene R • mpn radicals, their reduction under the action of irradiation and the restoration of [R • mpn] after the cessation of exciting light have been established.Polycyclic aromatic hydrocarbons with the participation of naphthene-paraffin hydrocarbons and olefins in the process of solar irradiation are also subjected to phototransformation with the formation of ion radicals, endoperoxides, quinones and phenols.All of the above radicals are very toxic and pose a great danger to the vital activity of the flora and fauna of the oil republic.

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.
