    Efecto de Aldicarb y Metamidofos en la tasa de desarrollo de Chrysomya Albiceps, Cochliomyia Macellaria e intervalo Postmortem
    (Universidad Privada Norbert Wiener, 2021-08-06) Canales Guillén, José Luis; Jáuregui Montero, José Antonio
    The importance of ghouls is known in the field of forensic investigations, since they are considered indicators of time of death or portmorten interval, however, there are factors that can influence them, such as the presence of certain toxins involved in the deaths either caused or accidental. In this sense, the objective of the present investigation was to determine the effects that the pesticides aldicarb and metamidifos exert on the biological development of two of the main species of forensic interest Chrysomya albiceps and Cochliomyia macellaria that are used for the evolution of the portmorten interval in the sciences. Forensics For this, three different doses 0.5LD50, LD50 and 2xLD50 of both toxic substances were inoculated in the food of these species. Post embryonic growth curves of Chrysomya albiceps and Cochliomyia macellaria were elaborated, based on length (mm), development time, taking into account the three doses of both pesticides; the rearing of both species was an average environmental temperature of 28.5 ºC, and an average relative humidity of 58.3%., which estimated the Postmortem interval (IPM). Based on the results of the present investigation, it can be concluded that the pesticides aldicarb and methamidophos inoculated at three different doses in their food (0.5LD50, LD50 and 2xLD50), influence the development rate of the two species Cochliomyia macellaria and Chrysomya albiceps, considered forensic indicators, this will inevitably influence the establishment of the Postmorten interval.

    Influencia del dactilograma policial y la identificación de personas en cadáveres nomen nescio de la morgue de Huancayo, 2019 al 2021
    (Universidad Privada Norbert Wiener, 2023-01-18) Vásquez Porras, Hernán Jesús; Jáuregui Montero, José Antonio
    In the investigation, dactyloscopy is not put into discussion as a method of identification and individualization of people, here what is considered as a sample element are police expertise. In them, the fulfillment of each of the fundamental moments of the dactylogram was evaluated, based on the fact that no type of blemishes or observations have been presented to the skills carried out in the VIII Dirtepol Junín, setting out the objective of the investigation; explain the influence of the police dactylogram in the identification of people in the nomen nescio corpses of the Huancayo morgue. Methodologically it is a thesis, analytical - deductive, quantitative approach, applied type, explanatory level and non-experimental design, transversal - retrospective, relational - explanatory, census sample of 56 expertise. Result and conclusion, Of the general objective, a p>0.05 and R2 of 31.8% to 60.2% establish that the null hypothesis is accepted: The police fingerprint does not influence the identification of people, of the corpses nomen nescio of the Huancayo morgue. Of the specific objectives that evaluate each of the fingerprint identification characters, specific objective 1 gives a p - value <0.05 and a percentage influence of 89.3%, establishing that: the first order (classification) character influences identification of people in corpses N.N. Of the specific objective 2, 3 and 4 give a p value >0.05 and an R2; 11.5% to 18.3%, 23.9% to 33.4%, 21.9% to 39.7%, respectively. Establishing that the subclassifying identification characters, infratype and characteristic points do not influence the identification of nomen nescio corpses from the Huancayo morgue, 2019 to 2021.
