In this paper, a stable analytical solution (without interference) was obtained for the wave field of longitudinal waves in a layered (discrete) ball of planetary size. The calculations of the total wave field, rays and travel-time curves of longitudinal waves for the spherical model of the Earth AK135 with a carrier frequency of 1 hertz are presented. The analytical solution showed that at angles smaller than 145 degrees ahead of the PKP‑waves, low-amplitude waves appear, with a higher frequency of about 1,3 hertz. Indeed, these high-frequency oscillations have the form characteristic for waves scattered at a certain object. The ray pattern and the travel-time graph show that these high-frequency oscillations are due to exclusively to the spherical geometry of the Earth. This could be explained by the interference of refracted and reflected longitudinal waves in the bottom of a discrete outer core. This field propagates even further towards smaller angles due to the interference of diffraction waves.","PeriodicalId":24047,"journal":{"name":"Доклады Академии наук","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83084104","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this concept, the conclusion regarding the presence of toxic substances in a sample, which is being analyzed, is connected with the inhibition of enzymatic reactions that are responsible for various functions of a live organism, such as luminescence, respiration, etc., these functions are taken as test functions in classical bioassays, which are using live objects (luminous bacteria, daphnia, algae, etc.). The regularities of the impact of different classes of toxicants on the activity of individual enzymes or coupled oligo-enzyme chains have been established. These enzyme reactions are selected as potential test objects - markers of pollution. The set of enzymatic bioassays consists of three enzyme systems with maximum sensitivity to different classes of toxicants: butyrylcholinesterase, NAD(P)H:FMN‑oxidoreductase + luciferase and lactate dehydrogenase + NAD(P)H:FMN‑oxidoreductase + luciferase.
