The answer to this question is of fundamental significance for the investigative authorities, since a dead person could have been submerged in the water to conceal the crime. Objective. Objectification of experts\u2019 conclusions about the duration of corpse\u2019s stay in the water on indicators of dispersion of electrical conductivity of its skin. Material and methods. Research aimed at objectifying the conclusions of experts about the duration of corpse\u2019s stay in the water on the indicators of dispersion of electrical conductivity of its skin was conducted using the experimental material from the corpses of 68 persons of different sex and age, who died for different reasons. Results. Three temperature ranges (1\u201424, 25\u201430, 31\u201440 \u00b0C) have been identified on the basis of regression analysis and mathematical models, describing the dynamics of electrical conductivity dispersion coefficient change depending on the duration of corpse\u2019s skin contact with the water of specified temperatures, have been created. Conclusion. Formulas for calculating the period of interest for the researcher have been developed and the boundaries of confidence intervals for each temperature range have been determined, taking into account its diagnostic applicability. A computer program has been written to facilitate routine calculations on the proposed method in order to simplify the practical application of the suggested procedure.<\/jats:p>","DOI":"10.17116\/sudmed20246705124","type":"journal-article","created":{"date-parts":[[2024,10,23]],"date-time":"2024-10-23T09:42:37Z","timestamp":1729676557000},"page":"24","source":"Crossref","is-referenced-by-count":2,"title":["Determination of duration of fresh water exposure on corpse\u2019s skin by dispersion value of its electrical conductivity"],"prefix":"10.17116","volume":"67","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9472-7264","authenticated-orcid":false,"given":"A.Yu.","family":"Vavilov","sequence":"first","affiliation":[{"name":"Izhevsk State Medical Academy","place":["Izhevsk, Russia"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5522-0292","authenticated-orcid":false,"given":"I.A.","family":"Rykunov","sequence":"additional","affiliation":[{"name":"Bureau of Forensic Medical Expertise","place":["Yugorsk, Russia"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"6743","reference":[{"key":"key-10.17116\/sudmed20246705124-1","doi-asserted-by":"publisher","DOI":"10.3389\/fmicb.2022.951707"},{"key":"key-10.17116\/sudmed20246705124-2","doi-asserted-by":"publisher","DOI":"10.1111\/1556-4029.13614"},{"key":"key-10.17116\/sudmed20246705124-3","doi-asserted-by":"publisher","DOI":"10.12116\/j.issn.1004-5619.2021.411019"},{"key":"key-10.17116\/sudmed20246705124-4","doi-asserted-by":"crossref","unstructured":"Pigolkin YuI.
