Cierre de comunicación oronasal mediante la utilización de doble colgajos rotativos palatinos y fibrina rica en plaquetas: relato de caso clínico
Authors: Pineda Edgardo , Moris Hilda , Medina Rodrigo , Lazo Diego , Mardones Marcelo
Published: November 2024

Oronasal communication (OC) is a rare muco-osseous defect, especially in adults. This defect communicates the oral cavity directly with the nasal cavity. There are multiple surgical options for treatment, among which are the local palatal flaps, characterized by receiving their blood supply through the greater palatine artery. We present a case of closure of a OC of traumatic origin in an adult female patient, who had undergone surgery on three previous occasions without achieving definitive closure of the OC. The surgical technique used in this case was a palatoplasty through a double palatal flap plus the use of platelet-rich fibrin as a scar adjuvant, as it has the characteristic of reducing the healing time in lesions. A successful long-term closure of the OC was obtained, achieving an airtight closure, without tissue tension and maintaining the blood supply of the flap. This surgical technique can be replicated in different cases of muco-osseous defects, having minimal complication rates and sequelae in patients, besides being a simple technique and of only one operative time, if compared to other surgical techniques.
Férulas de Gunning. Una alternativa de tratamiento que sigue presente. Reporte de 02 casos
Authors: Vizuete Bolaños Marco Xavier , León Hernández Berenice , Munive Landa Maricruz , González de Santiago Miguel
Published: November 2024

Las fracturas condilares continúan siendo un desafío para los cirujanos maxilofaciales, debido a los múltiples tipos de fracturas que pueden ocurrir y los tratamientos disponibles. El tratamiento de este tipo de fractura podría dificultarse si el paciente presenta edentulismo. Así, entre las opciones de tratamiento, el uso de una férula o la prótesis dental preexistente como medio de fijación se muestra como una opción viable. Se presentan 02 casos clínicos de pacientes masculinos de 36 y 83 años de edad que presentan un maxilar edéntulo y fractura de cóndilo mandibular de lado derecho; para su tratamiento se utilizó una férula de Gunning superior con fijación intermaxilar mediante el uso de tornillos de fijación intermaxilar y elásticos intermaxilares durante 4 semanas. Después de 3 meses de evolución, ambos pacientes presentaron una adecuada apertura bucal, sin desviaciones o limitación a la apertura bucal. Las férulas de Gunning, a pesar que actualmente son poco usadas, continúan siendo una opción apropiada para los casos de fractura del cóndilo mandibular en pacientes edéntulos.

Authors: Jaramillo-Gallego Steffany , Tovío-Martínez Eilien , Urbano-Del-Valle Samuel , Jaramillo-Monroy Sandra
Published: November 2024

El ameloblastoma multiquístico, una neoplasia odontogénica de crecimiento lento, pero comportamiento agresivo, suele manifestarse en la mandíbula, generando deformidades faciales, pérdida dentaria y desplazamiento de tejidos adyacentes. Este estudio tiene como objetivo describir el tratamiento quirúrgico multidisciplinario del ameloblastoma multiquístico en una localización inusual, destacando el compromiso de estructuras vitales y los estudios complementarios necesarios para un diagnóstico preciso. Se presenta el caso de un paciente masculino con una lesión en la hemicara izquierda, que se había desarrollado durante aproximadamente ocho meses, abarcando desde la región temporoparietal hasta la región maseterina ipsilateral. La evaluación clínica y radiológica inicial sugirió la posibilidad de un ameloblastoma multiquístico, confirmado posteriormente mediante biopsia. Como parte del equipo multidisciplinario del Hospital San Vicente Fundación de Medellín, se optó por una resección quirúrgica radical, que incluyó hemi-craneotomía y hemi-mandibulectomía, seguida de una reconstrucción exitosa. Se señala la importancia de un abordaje coordinado entre cirujanos maxilofaciales, estomatólogos y otros especialistas, así como la relevancia de los estudios complementarios para determinar el curso terapéutico óptimo. La cirugía reconstructiva demostró ser efectiva tanto en la restauración funcional como estética, aunque destaca los desafíos inherentes a la gestión de localizaciones poco comunes de esta enfermedad.

Authors: Osorio Mondaca Manuel
Published: November 2024

El artículo se centra en la aplicación de tecnología CAD/CAM en la odontología, específicamente en la fabricación de prótesis dentales totales. Este avance ha transformado la forma en que se diseñan y producen estas prótesis, emergiendo la fabricación de ella mediante capas sucesivas a base de tecnologías de impresión 3D como la estereolitografía, el procesamiento digital de luz y la pantalla de cristal líquido. En la presente revisión se profundizó en aspectos clínicos y biomecánicos, evaluando la retención, adaptación de la base, resistencia a la flexión y límite elástico de las prótesis. Los resultados indican que las prótesis digitales ofrecen mejor retención y adaptación en comparación con los métodos convencionales, aunque no hay diferencias estadísticamente significativas en resistencia a la flexión. También se exploraron aspectos económicos, destacando la reducción de costos y ahorro de tiempo en el proceso clínico con el enfoque digital. Los pacientes experimentan mayor satisfacción con prótesis impresas en 3D en términos de comodidad y eficiencia. Sin embargo, existen limitaciones, como la dificultad en la evaluación estética de prótesis monocromáticas, además de la dependencia de técnicas convencionales para evaluar la funcionalidad del paciente. La tecnología CAD/CAM ha revolucionado la fabricación de prótesis dentales totales, ofreciendo ventajas y beneficios. Este avance tecnológico promete mantener su relevancia en la comunidad científica y odontológica.

El objetivo del presente estudio fue determinar la prevalencia de monogeneos (Cichlidogyrus sp) en tilapia (Oreochromis niloticus) de estadio juvenil en el distrito de la Banda de Shilcayo, región San Martín, Perú. Se colectaron 180 tilapias procedentes de seis piscigranjas de peso y longitud promedio de 37.4 g y 9.56 cm, respectivamente. Se tomaron muestras de tegumento, branquias e intestinos. Se determinó una prevalencia de 76.1% de monogeneos, abundancia de 3.27 monogeneos/pez, intensidad media de 4.28 monogeneos/pez infectado e índice de dispersión de 0.75. Se colectaron 590 parásitos monogeneos del género Cichlidogyrus sp provenientes solo de branquias (100%). No se determinó relación entre la ubicación de los monogeneos dentro de los cuatro arcos branquiales, ni con peso, longitud de los peces y cantidad de monogeneos (p<0.05). Asimismo, las características fisicoquímicas del agua (temperatura, oxígeno, pH, CO2 y amonio) de las piscigranjas se mantuvieron dentro de los rangos normales.

Published: November 2024

The aim of this study was to evaluate the productive performance of growing guinea pigs, fed with green alfalfa forage and an artisanal supplement widely spread in the Mantaro Valley, Peru, made from wheat byproduct, whole yellow corn and soy cake in the base ratio of 3:2:1, compared to four commercial feeds, in terms of weight gain (BWG), feed conversion (FC), carcass yield (CY), and economic merit. In total, 60 male and female red-line guinea pigs, 18 ± 3 days old and weighing 318 ± 35 g, were used. They were distributed in five metal cages with four levels each. A randomized Complete Block Design was used considering sex as a block. The effect achieved by the artisanal supplement on BWG, FC and CY were similar to that achieved by two commercial products, but superior to the other two; however, it showed a better economic return in terms of unit profit margin and relative profitability due to the lower food cost recorded. It is concluded that the artisanal formulation is appropriate to be used in the fattening of guinea pigs due to its easy preparation and effectiveness in achieving an adequate productive response and greater economic remuneration.

Authors: Grandez R. Ricardo , Paz Bringas V. María , Muñoz D. Karina , Hermoza G. Catalina
Published: November 2024

The abdomen of apparently healthy jaguars (Panthera onca) kept in confinement at the Parque de Las Leyendas Zoo (Lima) and the San Juan Zoocriadero (Pucallpa, Peru) was evaluated by ultrasound. The work included the examination of 13 specimens, young and mature, female and male. The specimens were anesthetized with a combination of Dexmedetomidine and Ketamine, and Atipamezole was used as an antidote. The Esaote MyLabOne™ equipment and the 4-9 MHz microconvex transducer were used. The anatomical location, echotexture and architecture of the abdominal organs were evaluated. From the study it was possible to conclude that the ultrasound characteristics of the abdominal organs of Panthera onca specimens are similar to those described for other species of South American wild felines, varying in length, width or thickness in correspondence to the larger size of the jaguar; and that the characteristics of the abdominal organs do not differ significantly from those described for companion animals.
Ideas of uncountable objects in the literature written in ancient Greek: from meaningless occupation — to omniscience of Apollo and God
Authors: Prikhodko Elena
Published: November 2024

One of the prophecies of the seven astragals oracle from the Pisidian city of Termessus included the saying “to count the waves,” indicating the futility of the intended endeavor. The author seeks to ascertain the purposes behind the Greeks’ utilization of imagery pertaining to uncountable objects such as waves, grains of sand, stars, and others. Additionally, the author aims to explore the perceptions surrounding the act of counting these objects within both domestic and cultural-religious contexts. The article shows that this “incalculability” was attracted by the Greeks to express incommensurable and even opposite concepts. First, through expressions like “to count the waves”, the case was characterized as either impossible or meaningless and stupid. Secondly, countless stars or waves were recalled when there was a need to emphasize the incredibly huge number of objects being described. Third, thanks to Apollo’s revelation announced in the response of the Delphic oracle, the knowledge of the number of grains of sand and the size of the sea formed the basis of the formula of divine omniscience: “I know the number of grains of sand and the depths of the sea”. When the books of the Old Testament were translated, the Hebrew tradition began to speak in ancient Greek. In it, the uncountable objects were needed primarily to emphasize God’s promise to Abraham of the multiplicity of the Israelite people, and for comparisons as well as to describe God’s omniscience. The list of uncountable objects itself differed in part from the standards recognized by the ancient Greeks. The ancient Greek and Jewish traditions merged in Byzantine literature into a single stream of the Christian tradition. The lists of uncountable objects of both traditions have been combined and further expanded upon. The Greek tradinion’s designation for an impossible or meaningless endeavor was retained. Passages from the Old Testament with words of God’s promises to Abraham were quoted and retold. Comparison with uncountable objects was actively used. The Apollo’s revelation was recognized as a deception of this demon, torn away from Apollo and eventually given to God.
Philosophical disputation vs. skill duel: methods of interpreting Latin hagiography in the old norse "Clemens saga"
Authors: Zenkova Mariya
Published: November 2024

The Clemens saga is a biography of St. Clement of Rome, compiled in the 1220s from translations of two Latin hagiographical works, the Recogniciones and the Passio Sancti Climentis. The Old Norse author made the translation in accordance with the peculiarities of the “saga” style: he changed the narrative modus, added didactic comments on Latin book culture, and used motifs and elements from Scandinavian folk literature. In addition, the Clemens saga is almost devoid of the philosophical and dogmatic Christian discourses that characterize the Recollections. One of such episodes altered in content is the philosophical contest between Faustinianus and his three sons - Aquila, Nikita and Clement, touching upon important questions of being from a Christian position and refuting epistemological views. In the Clemens saga this plot takes the form of a contest in the Seven Liberal Arts between Faustinianus and Clement, caused by a misunderstanding of the consubstantial nature of the almighty God. Despite the fact that a contest in skills or a duel is a frequent plot in Scandinavian sagas and poetry, comparing their structure and literary motifs with the Clemens saga, we can conclude that the author, interpreting the original, does not rely on examples from his own popular culture. Instead, he turns to Latin secular literature, turning the philosophical disputation into a contest in the Seven Liberal Arts, which are rarely found in the saga corpus. By combining methods of interpretation with reliance on Latin secular and religious or Scandinavian folk literature, the scribe not only influences the structure and style of the text, but also its content.
Circular Intuitionistic Fuzzy ELECTRE Approach: A Novel Multiple-Criteria Choice Model
Authors: Chen Ting-Yu
Published: November 2024

This paper presents a multiple-criteria choice model, the circular intuitionistic fuzzy (C-IF) ELECTRE, designed to resolve C-IF ambiguities through built-in circular functions. Joint generalized scoring functions establish contrast relationships between C-IF evaluation values, facilitating concordance and discordance analyses for option ranking. The efficacy of C-IF ELECTRE I and II—leveraging tools such as the prioritization Boolean matrix, average outflows and inflows, and overall net flow—is validated through a multi-expert supplier evaluation, with outcomes benchmarked against alternative methods. A comparative analysis explores the impact of parameter variations, underscoring how integrating C-IF sets with ELECTRE enhances decision-making in complex, multifaceted environments.

The Dictionary contains a comprehensive range of socio-political vocabulary, encompassing both older and contemporary, reflects the dynamic growth of its lexicon in response to significant restructuring of society’s social structures and changes in the political system, a re-evaluation of the meaning of existing terminology, and the re-evaluation of existing terms and their semantic nuances. The article outlines the key terms and concepts that are most commonly used in the social sciences, including philosophy, ethics, ecology, aesthetics, political science, sociology, sociology of law, conflictology, international relations, psychology, and cultural studies. The Dictionary of Modern Social and Political Lexicon (1991–2022) has been compiled with the objective of providing an overview of the practical experience gained through previous research in the Ukrainian social and political domain, and of recording the most recently developed vocabulary in this field. In the proposed work, the new terms are recorded with regard to various criteria: time of appearance, conditionality (linguistic or extra-linguistic), usage and word-formation meaning. The material is presented in an alphabetical and nested format, applying the logical-conceptual method and the method of lexical and grammatical ordering. The terms selected from media materials belong to the main lexical and semantic groups: terms of the state-territorial structure: state executive and administrative bodies of power; names of representatives of governmental structures; names of normative legal acts; processes; social phenomena; forms of state power and forms of government; signs and symbols of the country; properties; political science. To confirm the existence of a word in the language, to reveal its meaning, syntactic relations, and use in a certain verbal surrounding, the words of the register are illustrated with examples of their usage in the media or scientific sources.

The Barbara Procession Among Burgenland Croats in Horvátkimle in the 20th and 21st Centuries
Authors: Bognár Szabina
Published: November 2024

The term “Burgenland Croats (Gradišćanskih Hrvati)” was coined by vicar, poet and scholar Mate Mersich Miloradić in 1921, after the majority of Western Hungary's Croatian population became annexed to Austria. By the interwar period an extended use of the term became the norm – it had come to refer to all Croatians living in the remaining areas of the Croatian diaspora, such as Western Hungary, Western Slovakia and Moravia, who had settled in these parts after fleeing the ravages of the anti-Ottoman wars of the 16th century. Worries about the mere existence and survival of the identity of the Burgenland Croat population has been a concern for well over two hundred years. It is fair to ask the question what kind of traditions the collector can expect to find and whether traditions are still in a collectable state in the 21st century, as we approach the 500th anniversary of the re-settlement of this population in Western Hungary. In the present paper I take the example of a specific custom, the Barbara procession of Horvátkimle, to show what it means for a community if one of their practices comes to be included on the ethnographic map of the country. We explore what sort of chances a community has to revive traditions that it had believed to be lost time and time again, and how it affects the life of the community if it succeeds in breathing new life into old traditions by accepting and adapting to the spirit of the times. The paper focuses not on the vanishing traditions, but on resilient tradition constructs that have proved flexible enough to survive. It concentrates not on the signs of the disappearance and assimilation of an ethnic community, but on the scenes and means of preserving such identity. I shed light on the role of individuals and of ethnographic scholarship in the process of preserving traditions.

The Seasonality of Labour in Ceramic Production and Agriculture in the Ancient Greek Rural World
Authors: Tomei Francesca
Published: November 2024

This article explores the seasonality of labour in ceramic production and its correlation with agricultural tasks, focusing on a Hellenistic kiln site in Sant’Angelo Vecchio, southern Italy, in the hinterland of Metaponto. Through a comprehensive examination of archaeological data and the outcomes of an experimental archaeology project, the study estimates the labour required for various stages of the pottery-making operational sequence. The findings reveal that small-scale rural workshops mainly produced limited quantities of items primarily for household and agrarian use. Only two or three individuals, working part-time, were needed to manage the various tasks involved, such as raw material collection, transportation, clay preparation, vessel shaping and kiln firing. The findings also demonstrate that the seasonal nature of their pottery work could be fitted within the seasonal rhythms of agricultural activities. This research highlights the interconnectedness of all productive activities in the region; sites and tasks are intricately linked, fostering a flexible and seasonal labour system in both ancient and modern Mediterranean societies.
A Religião e seus privilégios: a representação da interação argumentativa em Mateus 4:5-7
Authors: Carvalho Silva Fagner , Nascimento Lucas
Published: November 2024

O cristianismo é uma religião ocidentalizada, no entanto, encontramos as suas raízes no judaísmo, especificamente no judaísmo do segundo templo quando muitos textos foram produzidos. O presente estudo visa demonstrar a profícua contribuição da análise dialógica da argumentação como método de interpretação bíblica. Assim, prioriza-se a apresentação da noção de evento polêmico literário, a qual pode ser entendida como a simulação de uma polêmica entre duas personagens que representam posicionamentos antagônicos em um dado cronotopo. Analisaremos, para tanto, a segunda interação argumentativa entre as personagens Jesus e Diabo no evento polêmico literário da tentação de Jesus, materializado no Evangelho de Mateus 4:1-11.

Apresentação do Dossiê - O discurso religioso: sentidos, práticas e dissensos
Authors: Da Silva Carneiro Marcelo , Kibuuka Brian Gordon Labuto , Terra Kenner Roger Cozalotto , Nascimento Lucas
Published: November 2024

O discurso religioso configura-se como um objeto multifacetado de análise, transcendente a uma mera expressão de fé ou espiritualidade. Ao adentrar os meandros da linguagem sagrada, o discurso religioso articula, de maneira singular, práticas de poder, interações sociais e epistemologias próprias (Foucault, 1999). Neste sentido, a religião, enquanto fenômeno discursivo, desempenha papel fundamental na construção de subjetividades, legitimações políticas e formas de controle social (Habermas, 2019). Para entender as suas dinâmicas, torna-se imprescindível a análise do seu funcionamento dentro das esferas de discurso institucionalizado, que inclui desde a exegese teológica até a oralidade presente nas liturgias (Barthes, 2011).
Discurso de Violência no Apocalipse de João e o corpo feminino: linguagem e poder
Authors: Terra Kenner
Published: November 2024

A linguagem apocalíptica é perpassada por símbolos de violência e esperança. No limite das metáforas, as imagens discursivas nessa literatura são instrumentos de construção de identidade e organização de mundo. Seguindo essa tradição do segundo templo, o visionário João convida seus interlocutores das sete igrejas da Ásia interpretarem o Império Romano como habitação do caos, o que exigiria das comunidades de fé da região asiática do primeiro século rigoroso ascetismo. Como contradiscurso, o Apocalipse contraria a propaganda imperial de ordem e pax descrevendo a realidade como habitação do dragão (Ap 12-13;17), o que exigiria total separação cultural. Sua estratégia discursiva, como defendem as atuais pesquisas, à luz das análises discursivas, estabelece fronteiras rigorosas nas quais se fortalecem os limites simbólicos dos seguidores do cordeiro ou da besta. Nesse cenário de construção de identidade, a corporeidade feminina é tratada no Apocalipse como parte do sistema maligno. Seguindo as orientações metodológicas que compreendem o texto como resultado estratégias de enunciação, a partir das teorias do discurso, o capítulo mostrará como as imagens vinculadas imageticamente ao feminino servem material simbólico no discurso ascético de João. A hipótese deste ensaio é que a linguagem do Apocalipse, a despeito de apresentar uma dura crítica ao Império, ao mesmo tempo fortalece a violência de gênero e tem potência de legitimação da misoginia, o que nos obriga ler o texto com cuidado crítico e inversão simbólica.

In this work, for the first time, an approach was suggested for determining the pKa of triazolo[5,1-c][1,2,4]triazine compounds in N,N-dimethylformamide using potentiometric titration. It was noted that change in system potential in the titration curves of triazolo[5,1-с][1,2,4]triazine are observed for compounds containing either H+ located at the nitrogen atom in position 1 or an –NH2 group. The calculated pKa values of the studied molecules correspond to the pKa values of moderately strong acids and are in the range of 2–8. The relationship was established between the acidity of the heterocyclic fragment and the presence of electron donor substituents. The obtained pKa values of the compounds correlate with the calculated possible deprotonation centers of the molecule. It was found that determining the acidity constants of substances is useful for clarifying the mechanisms of their transformations. The possibility of establishing a relationship between the structure of the compound, pKa, and probable biological activity was shown.
Plano estadual de educação de São Paulo (2016-2026): debates e embates
Authors: Jacomini Márcia Aparecida
Published: November 2024

Resumo Este artigo tem o objetivo de analisar a participação da sociedade civil e da sociedade política e a construção de hegemonia no processo de elaboração e aprovação do Plano Estadual de Educação (PEE-SP 2016-2026). Foi realizada uma pesquisa de abordagem qualitativa, envolvendo entrevistas semiestruturadas e análise documental. A análise do processo de construção do plano de educação paulista sugere que a Secretaria de Educação (Seduc) não tinha efetivo interesse em discutir a política educacional paulista num Fórum que congregava um conjunto de entidades que foram alijadas das decisões educacionais nas duas décadas anteriores, principalmente porque os interlocutores da Seduc eram setores da sociedade civil vinculados ao capital. À vista disso, pouco se avançou no planejamento educacional com o PEE-SP 2016-2026.
Geosynthetic-stabilized aggregate: quantitative modulus evaluation via bender element
Authors: Wang H. , Kang M. , Kim Y. , Qamhia I. I. A. , Tutumluer E. , Shoup H.
Published: November 2024

Geosynthetics, mainly geogrids and geotextiles, are commonly used to mechanically stabilize unbound aggregate layers in paved road applications. They provide lateral restraint to aggregates to initially increase the layer modulus during construction and minimize its time-dependent decrease under vehicular traffic loading. Different types of geosynthetics may provide different improvement mechanisms and stiffness enhancement levels. Quantitative evaluation of various stabilization geosynthetics is presented herein to compare modulus improvement trends and help incorporate geosynthetic benefits into state-of-the-art mechanistic-empirical (M-E) pavement design procedures. Five geogrids (three extruded, one woven, and one welded) and two geotextiles (one woven and one nonwoven) were studied with a dense graded aggregate in laboratory triaxial testing. Geosynthetics were placed at specimen mid-height and three pairs of Bender Element (BE) sensors were placed at various heights above the geosynthetic to collect shear waves and quantify the degree of mechanical stabilization during resilient modulus testing. While resilient moduli did not distinguish effectiveness of different geosynthetics, shear wave measurements could clearly show local stiffness increases achieved with geosynthetic inclusions. Meanwhile, trends observed in shear modulus profiles at various distances from the geosynthetic, when compared to that of control specimen, properly established the modulus enhancement level achieved in mechanical stabilization with geosynthetics.

Subcritical convection in colloids and liquid binary mixtures with positive thermal diffusion
Authors:   Perm State University, Glukhov Alexander F.
Published: November 2024

The paper analyzes convection of molecular binary mixtures and colloids with positive thermal diffusion that occurs in the case of heating from below and below the equilibrium stability threshold for a homogeneous liquid. The convection is pulsed in nature and is realized in the form of periodic bursts. Positive thermal diffusion displaces the heavy component into the upper cold layers of the liquid. There, the heavy component accumulates in the boundary layer, forming a growing unstable density stratification. When the inhomogeneity exceeds the critical value for a given geometry, a convective surge occurs, and the heavy component moves down to a stable position. The study has found the critical thickness of the boundary layer, the critical concentration difference at the boundaries of the cavity, and the time at which instability occurs. Based on the analysis of the problem of the concentration profile dynamics under the influence of gravitational sedimentation and thermal diffusion, experimental facts are explained – periodic convective bursts of the binary mixture in channels and in the Hele-Shaw cell below the critical Rayleigh number. The described mechanism probably explains the convection observed by other experimenters in a horizontal flat layer of magnetic fluids below the critical Rayleigh number at Ra < 1708.

Introduction of small additives of thermoplastic polymer into the elastomer matrix is one of the simple and effective ways to improve the complex of physical and mechanical properties of rubbers. This article is devoted to the study of the effect of low-density polyethylene (HDPE) grade 273-83 and ultra-high molecular weight polyethylene (UHMWPE) grade GUR 4113 on the vulcanization characteristics of rubber compounds, physical and mechanical properties and resistance to thermal aging of vulcanizates based on ethylene propylene diene rubber grades SKEP-40 and SKEP-50. The use of HDPE and UHMWPE as additives is of interest not only due to their properties, but also due to their similar chemical nature to SKEP. It is shown that the introduction of polyethylene additives leads to some increase in the duration of the rubber compounds in the viscous flow state and the vulcanization optimum. Vulcanizates containing polyethylene additives are charac-terized by an increase in the conventional stress at 100 % elongation and a decrease in the relative elongation at break, which indicates an increase in the rigidity of the vulcanizates. In the presence of PE, wear resistance and the ability to elastic-elastic recovery of vulcanizates after compression also increase significantly. The frost resistance coefficient of rubber samples containing UHMWPE remains at the level of the original vulcanizates, and in the case of HDPE it decreases significantly, which can be explained by the better ability of UHMWPE to maintain its flexibility at low temperatures. According to the results of accelerated thermal aging, it was found that the presence of polyethylene additives leads to a significant increase in the stability of the elastic-strength properties of vulcanizates based on SKEP-50. Moreover, the higher the molecular weight of polyethylene, the higher its efficiency. It should be noted that in the DOT-4 environment, vulcanizates are characterized by a greater degree of preservation of elastic-strength indicators compared to the air environment, which is due to their high resistance to this working environment. It was found that UHMWPE, compared to HDPE, results in the production of an elastomeric material based on EPDM with a more optimal set of physical and mechanical properties and increased stability of elastic strength indicators after thermal aging.

The aim of the work is to analyze changes in the maximum optimal flow rates of wells operating various groups of productive formations of the Volga-Ural oil and gas province under conditions of uncertainty of geological and field data. The relevance of the work is due to the deterioration of the structure of residual oil reserves and the need for the most efficient extraction of liquid hydrocarbon resources, optimization of design methods for various treatments of the bottomhole formation zone. Using geological and statistical modeling systems, the timing of cleaning the bottomhole zones of wells from drilling products was determined at the time they reached their maximum optimal flow rate in conditions of deposits confined to various stratigraphic horizons, and appropriate models of changes in productivity coefficients were constructed. The factors influencing the recovery time of the real properties of the reservoir at the point of opening it by the well, which, among other things, determines the profitability of the process of selecting residual oil reserves, have been established. Among them, the most relevant and necessary for the implementation of an integrated approach to computer support procedures for the development of oil fields are the productivity of wells, fracturing of formations, their proximity to a particular tectonic-stratigraphic complex, geological, physical and physico-chemical properties of formations and their saturating fluids. For the deposits of the Famensk tier of deposits of the Volga-Ural oil and gas province, a multiple decrease in the time of removal of reaction products after hydrochloric acid exposure at objects with low fracturing has been established. At the same time, additional processing of the bottomhole formation zone within areas with high drilling density does not affect the total cleaning time of the bottomhole zone of wells. Stimulation of the removal of drilling mud filtrate and additional products of formation reactions by injection of hydrochloric acid compositions under certain conditions can lead to a decrease in the actual productivity of wells due to the introduction of less developed and dead-end cracks into the drainage process. The existence of the specifics of the procedure for cleaning the bottomhole formation zone depending on the geological and physical parameters of productive formations is substantiated and various patterns of changes in the productivity coefficient depending on the time of wells reaching the maximum optimal flow rate are revealed. The results obtained make it possible to make informed technological decisions to improve the efficiency of oil production, including in conditions of uncertainty, which may be caused by the lack of the necessary volume of hydrodynamic studies of wells.
