Published: September 2024

MulminaTM mango juice is the brand name of the formulation containing Mangifera indica L., Centella asiatica, Curcuma longa, essential vitamins and minerals. MulminaTM is natural immune booster and stress reliever. The present study is to investigate the effect of MulminaTM mango juice for its anti-allergic property by in vivo models like: Compound 48/80 induced mast cell degranulation in rat mesentery, rat peritoneal fluid, milk induced leucocytosis and eosinophilia in mice and systemic anaphylaxis in mice. MulminaTM mango juice exhibited potential anti-allergic property with marked reduction in number of degranulated cells, reduction in antigen (milk) induced immunological reaction by lowering leucocytes and eosinophil count and showed protection against histamine induced anaphylactic shock. These results constitute the first report of the anti-allergic properties of MulminaTM mango juice on allergic models, as well as suggesting that this natural fruit juice could be successfully used in the allergic conditions.

Objective: The main objective of this study is to produce and characterize the raw material used to manufacture beer, including planting and harvesting by one of the largest brewing groups in the country, the Petropólis group, with a unit installed in the city of Uberaba/MG with a built area of 108,000 m².
 
Theoretical Framework: Most hops used for brewing in Brazil are imported from countries such as Germany and the United States. However, certain varieties have adapted to the Brazilian climate and achieved significant yields and qualities.
 
Method: Hop samples were collected in the city of Uberaba-MG. Mettler Toledo® moisture content measuring equipment, model HE53, was used. The hop samples were dried in the Pardal® New Hobby model dehydrator. In the granulometric analysis, the Tyler series of sieves was used. Color was measured using an Eoptis® reflectance colorimeter, model CLM-194.
 
Results and Discussion: The hop cones, after drying stages, presented an average content of 91.67% of dry matter. The color difference between the dried leaves and the dried/ground hop cones, in relation to the standard, were ΔE = 64.16 and 57.77 respectively. The average Sauter diameter was 0.0347 cm.
 
Research Implications: The Petrópolis group invests in planting hops that will enable the creation of a final product with its own identity in the future, which are beers produced with its own hops. Cultivation began with an area of ​​two hectares planted.
 
Originality/Value: The group plans to double the plantation area and claims it is a promising business for the future, where many producers will invest in this cultivar, as today it is entirely possible to apply techniques such as prolonged lighting and irrigation systems.

Rare-earth minerals in pre-Cambrian rocks of the Lyapinskii anticlinorium (Subpolar Urals)
Authors: Grakova O. V. , Popvasev K. S.
Published: September 2024

Research subject. REE-containing minerals in metamorphic pre-Cambrian rocks of the northern part of the Lyapinskii anticlinorium of the Subpolar Urals. Aim. To establish typochemical features and conditions for the formation of rare-earth minerals in the studied rocks. Materials and methods. Chemical compositions and photographs of minerals were obtained using a JSM-6400 scanning electron microscope with a Link energy spectrometer and a Tescan Vega 3 LMH with an Instruments X-Max energy-dispersive attachment. The content of rock-forming oxides was determined by the gravimetric chemical method. The contents of rare and rare-earth elements were determined using an Agilent 7700x inductively coupled plasma mass spectrometer. Results. Rare earth carbonates and titanoniobates were identified in the pre-Cambrian rocks of the Subpolar Urals. In the mica garnet-bearing crystalline schists of the Nyartinskii complex, ankylite-(Ce) and hydroxylbastnäsite-(Ce) were identified for the first time, and hydroxylbastnäsite-(La) was identified in the actinolite-bearing quartz-albite-epidote-chlorite schists of the Puyva Formation. In the metarhyolites of the Sablegorskii Formation, the typochemical features of bastnäsite-(Ce), kainosite-(Y), and аeschynite-(Y) were studied. Ankylite-(Ce), hydroxylbastnaesite-(Ce), and hydroxylbastnaesite-(La) from Lower Proterozoic and Upper Riphean metamorphic rocks were probably formed during metamorphogenic-hydrothermal processes in the presence of minerals containing rare-earth elements and with the participation of carbon dioxide solutions. A scheme for the formation of rare-earth minerals was proposed for the metarhyolites of the Upper Riphean-Vendian Sablegorskii Formation. Aeschynite-(Y) was probably formed as a result of the transformation of rhyolites, due to the presence in the residual melt of increased concentrations of some rare metals, i.e., Zr, Nb, Y, and REE. As a result of metamorphogenic-hydrothermal processes, bastnäsite-(Ce) replaces allanite-(Ce). Kainosite-(Y) in metarhyolites is the latest mineral, formed due to the recrystallization of allanite-(Ce) and bastnäsite-(Ce) during the decomposition of аeschynite-(Y). Conclusions. The study of REE-containing minerals in Precambrian rocks of the Lyapin anticlinorium found that rare-earth titanoniobates were formed during the post-magmatic stage of metarhyolite transformation. The formation of rare-earth carbonates may be associated with metamorphic and hydrothermal processes.

Published: September 2024

Research subject. Microfauna of the Mikitovian Formation, Lower Carboniferous, Severny Island, Novaya Zemlya Archipelago. Mikitovian Formation is confined to the Severonovozemelskaya structural-facies zone. The section of the Goryakov Peninsula is a parastratotype of the Mikitovskaya Formation, characterized by a more carbonate composition of sedimentary rocks in contrast to the stratotype located on the Schmidt Peninsula. Aim. To clarify the age and to determine the boundaries of stratigraphic units based on a detailed study of foraminiferal communities in the Upper Tournaisian–Lower Visean terrigenous-carbonate deposits of the Mikitovian Formation. Materials and methods. Micropaleontological and microfacial studies of the collection of thin sections from the parastratotype of the Mikitovian Formation. Results. A foraminiferal sequence was revealed: the Spinoendothyra costifera Zone of the Kizelian Horizon and Eotextularia diversa–Dainella chomatica Zone of the Kosvian Horizon of the upper Tournaisian and the Eoparastaffella simplex Zone of the Pesterkovian Horizon and Viseidiscus primaevus Zone of the Ilychian Horizons of the Lower Visean, generally corresponding to the foraminiferal zonality of the General Stratigraphic Scale (GSS) of Russia. There are genera and species of foraminifera, characteristic of the eastern and northeastern regions of Russia, along with taxa widely distributed in the Urals and the East European Platform in microfaunal assemblages. The identified subdivisions are correlated with the zones and horizons of the western slope of the Urals. The dependence of the composition of the revealed microfaunistic complexes on their facies confinement is considered. Conclusions. The substantiated stratigraphic subdivisions of the Late Tournaisian–Early Visean interval make it possible to clarify the previously proposed regional schemes of Novaya Zemlya and to distinguish zones and horizons of the West Ural Subregion and the GSS of Russia instead of beds with fauna.
La ética animal como campo de producción de figuraciones políticas
Authors: Ávila Gaitán Iván Darío
Published: September 2024

Resumen: En este artículo se realiza una lectura del campo de la ética animal como espacio de producción de figuraciones políticas. En un primer momento, se aborda la comprensión de la ética animal no solo como campo de estudios, sino como campo de fuerzas en el que emergen diversos conceptos cargados histórica y políticamente. Estos conceptos son percibidos como figuraciones, es decir, modos de hacer alusión a la realidad que implican necesariamente su alteración. En un segundo momento, se examinan las figuraciones del especismo, el animal como ser sintiente, como sujeto (de una vida), como esclavo y sujeto susceptible de liberación y, finalmente, como sujeto sintiente-consciente. La conferencia concluye con un espacio de diálogo en el que se realizan precisiones sobre el problema de la sintiencia y se exploran temas como los veganismos, la sujeción y la ciudadanía animal.
La animalización como estrategia política. El caso del presidente de Costa Rica, Rodrigo Chaves Robles
Authors: Sequeira Rovira Paula
Published: September 2024

El presente artículo examina referencias hacia la animalización como una estrategia política para desprestigiar, sexualizar y hasta exaltar ciertas características que generalmente están ligadas a la figura de masculinidad del hombre fuerte y poderoso. Específicamente se analizan estas asociaciones vinculadas a referencias históricas y particularmente a la figura del actual presidente de Costa Rica, Rodrigo Chaves Robles. Para esto último, se revisaron diversos documentos mediante el análisis crítico del discurso (ACD). Las pruebas históricas muestran evidencias de cómo se utiliza la figura de los animales y de la naturaleza para tratar de subordinar a otras personas. En el caso de Chaves Robles, los usos del vocabulario zoomórfico se ligan a la sexualización de las mujeres, a producir una calificación despectiva de los adversarios políticos, a presentarse como un símbolo de poderío y a buscar alejarse de cualquier tipo de ambigüedad de una relación absolutamente simbiótica entre animales y humanos.
El consentimiento informado: una barrera para el respeto irrestricto al derecho a la protección de datos personales

Published: September 2024

El presente artículo presenta una serie de reflexiones respecto la política que regula el tratamiento de datos personales, en especial los datos sensibles relacionados con la vida íntima, personal, sexual, laboral o familiar de las personas y que están manejados por entidades que prestan servicios de salud. Colombia es uno de los países de América Latina que se ha sumado a la estrategia de incorporar al ordenamiento jurídico una regulación general de protección de datos personales, sin embargo, el instrumento jurídico resulta ineficaz a la hora de garantizar una política de tratamiento íntegra de la información sensible por cuenta de los operadores en el área de la salud, sin brindar garantías reales en el proceso de recopilación, almacenamiento, uso, actualización y transferencia, convirtiendo el consentimiento informado en una entrega de la intimidad del usuario del servicio de salud como requisito para acceder a un procedimiento médico
O modelo de dependências universais: assentando bases teóricas e revisando diretrizes metodológicas
Authors: Coneglian André Vinicius Lopes
Published: September 2024

As Dependências Universais (UDs) são um modelo de anotação morfossintática de línguas naturais. Este artigo parte do pressuposto de que na base do modelo ficam previstas a adequação computacional (que se liga ao processamento de língua natural), a adequação tipológica (que se liga à proposta geral do modelo de comparação interlinguística) e a adequação descritiva (que se liga à anotação de línguas individuais). A discussão concentra-se nos dois últimos tipos de adequação. A proposta que se defende aqui é a de que os pressupostos teóricos subjacentes ao modelo das UDs necessitam ser claramente explicitados, uma vez que são exatamente tais pressupostos que determinam a construção de quadros categoriais que chancelam as anotações realizadas para línguas individuais. Para tanto, procede-se a uma discussão sobre a concepção do quadro categorial e a formulação da definição das categorias. A avaliação geral a que se chega é que, por um lado, do ponto de vista da proposição de diretrizes gerais, tal quadro categorial deve constituir um conjunto de “conceitos comparativos” (HASPELMATH, 2010), por outro, do ponto de vista da proposição de diretrizes para anotação de línguas individuais, esse quadro deve constituir um conjunto de “categorias descritivas”. Essa dupla visão sobre o quadro categorial das UDs pode garantir isonomia e equivalência teórico-metodológica, de modo a tanto otimizar a realização de tarefas de análise e descrição linguísticas assistidas por modelos computacionais quanto a construção de modelos computacionais baseados em anotação linguística consistente do ponto de vista descritivo e tipológico.

Published: September 2024

A capacidade mental de fazer comparações é comum a todos os seres humanos, porém as formas de expressar comparações nas diversas línguas são muito variadas e a gramaticalização de algumas formas deu origem às chamadas “construções comparativas", que são estruturas complexas, altamente frequentes e versáteis, usadas para expressar avaliações sobre diversos tópicos. Atualmente, devido ao grande volume de avaliações feitas por usuários na Web, cresceu o interesse pelo processamento automático das construções comparativas, com o objetivo de inferir, por exemplo, qual o tópico da comparação, com o que esse tópico está sendo comparado, qual o parâmetro de comparação e se o que está sendo expresso pela comparação é positivo ou negativo. O primeiro requisito para facilitar o processamento automático das construções comparativas, de modo a permitir a extração automática de informações, é que elas sejam anotadas de uma forma lógica e consistente. Com foco nesse objetivo, apresentam-se, neste artigo, diretrizes de anotação de estruturas comparativas em língua portuguesa usando o conjunto de etiquetas proposto pelas diretrizes de anotação das Universal Dependencies. Os estudos que embasaram essa proposta envolveram a revisão de trabalhos de tipologia das línguas e trabalhos específicos da língua portuguesa. As diretrizes foram testadas no córpus Porttinari-base (Pardo et al., 2021; Duran et al. 2023), e aperfeiçoadas até alcançarem o estágio aqui apresentado. O conjunto de 122 sentenças anotadas está disponibilizado na Web, dentro do ambiente de anotação Arborator-Grew-NILC (Miranda & Pardo, 2022).

Authors: Dayakar M.M. , Pooja H. , Prakash Pai Pai G. , Shivananda H.
Published: September 2024

Objectives

The cross-sectional study to evaluate the ability to categorize gingival phenotype according to gingival thickness (GT) using colored periodontal probes (CPP) and a traditional steel probe (SP).

Material and Methods

A total of 150 patients (n = 900) had three anterior teeth examined; the buccal GT in those teeth was assessed by transgingival sounds and categorized using two distinct methods. Specifically, it assessed diagnostic reasons for how well a standard periodontal probe (SPP) could differentiate between thin and thick gingiva, and a CPP could distinguish between medium, thick, and extremely thick gingiva. GT was assessed using transgingival evaluation at a distance of 2 mm from the gingival edge. Based on corresponding GT, thin and thick phenotypes were identified as being ≤1 mm and >1 mm, respectively. Using the transparency approach, the gingival phenotype was ascertained using SPP and a color-coded probe (CCP). Furthermore, keratinized tissue width (KTW) was assessed. Thin and thick gingival phenotypes were identified using experimental periodontal probes, and their diagnostic accuracy was compared.

Results

Nine hundred gingival sites were analyzed, transgingival technique classified 40% (n = 360) thin phenotypes (GT: 0.78 ± 0.12 mm, 3.52 ± 1.11 mm) and 60% (n = 540) thick phenotypes (GT: 1.22 ± 0.28 mm, 4.61 ± 1.1 mm). Similar diagnostic accuracy values of 0.69 and 0.70 were recorded for the SPP and CCP, respectively.

Conclusion

Identification of gingival phenotype maxillary anterior tooth achieved with comparable efficacy both color-coded plastic probe and SP.

Published: September 2024

Objectives

Cleft lip and palate (CLP) patients are prone to opportunistic infections by Staphylococcus and Candida. This study aimed to assess oral Staphylococcus and Candida in a group of Sri Lankans with CLP.

Material and Methods

Oral swabs were collected from 52 CLP patients preoperatively upon their informed assent. Staphylococcus and Candida were isolated microbiologically. Methicillin resistance (MR) of staphylococci was assessed using cefoxitin disk diffusion. Candida species were identified using germ tube test and chrome agar.

Results

The study included 52 (male=27, female=25) CLP patients (mean age = 9.4 ±3.6 months). Oral prevalence of Staphylococcus and Candida were 65.4% (34/52) and 23.1% (12/52), respectively. Whereas 11.5% (6/52) of patients carried both Staphylococcus and Candida, 11.5% (6/52) had neither organism. Staphylococci included 41.2% (14/34) S. aureus and 58.8% (20/34) coagulase-negative staphylococci (CoNS). MR was detected in 57.1% (8/14) of S. aureus and 55% (11/20) of CoNS. Candida included 58.3% (7/12) C. albicans and 41.7% (5/12) non-C. albicans Candida.

Conclusion

Considering the high prevalence of Staphylococcus with MR along with pathogenic Candida species, proper infection control practice, and meticulous postoperative care would be mandatory to avoid post-operative complications in CLP patients in this study setting.

Application of Physical Unclonable Functions for Authentication in the Internet of Things Networks
Authors: Мустафаев А.Г.
Published: September 2024

Недостаток вычислительных ресурсов и низкая энергоемкость устройств Интернета вещей сужают список методов защиты, которые могут быть реализованы на этих устройствах. Большинство устройств Интернета вещей являются «закрытыми» для изменения встроенной в них информации. Поэтому все защитные механизмы, или их поддержка, должны быть изначально спроектированы и встроены в устройства Интернета вещей, чтобы они были безопасными по своей архитектуре. Физически неклонируемые функции могут быть использованы как надежное и не требующее ресурсов решение для аутентификации устройств Интернета вещей. В работе рассматривается механизм аутентификации устройства в инфраструктуре Интернета вещей, основанный на физически неклонируемых функциях, являющихся базовым элементом физической криптографии. Для надежной аутентификации используются уникальные цифровые идентификаторы интегральных схем, формируемые на этапе производства.

Lack of computing resources and low power consumption of Internet of Things devices narrow the list of protection methods that can be implemented on these devices. Most IoT devices are «locked» for changing the information embedded in them. Therefore, all protective mechanisms, or their support, must be initially designed and built into Internet of Things devices, so that they are safe in their architecture. Physical unclonable functions may be used as a reliable and resource-free solution for authenticating Internet of Things devices. The paper considers the mechanism of device authentication in the infrastructure of the Internet of Things, based on physically non-cloning functions, which are the basic element of physical cryptography. Unique digital identifiers of integrated circuits, formed at the production stage, are used for strong authentication.

Published: September 2024

В статье синтезируется ранговый алгоритм селекции режимов радиоизлучения в условиях разнородности источников и возможного наличия взаимных помех. Решающие статистики алгоритма формируются на базе регистрируемых в ходе наблюдения характеристик радиоизлучения. Каждая статистика трансформируется в строку рангов по числу распознаваемых режимов. В совокупности эти строки образуют таблицу (матрицу) ранжирования. Текущая обработка наблюдения при этом состоит в формировании рангов для используемых решающих статистик, а распознавание режима осуществляется либо в соответствии с таблицей ранжирования, либо с использованием дополнительной процедуры голосования «2 из 3х».

The article synthesizes a ranking algorithm for the selection of radio emission modes in conditions of heterogeneity of sources and the possible presence of mutual interference. The decisive statistics of the algorithm are formed on the basis of the characteristics of radio emission recorded during the observation. Each statistic is transformed into a row of ranks according to the number of recognized modes. Together, these rows form a ranking table (matrix). The current processing of the observation in this case consists in the formation of ranks for the used decision statistics, and the recognition of the mode is carried out either in accordance with the ranking table, or using the additional voting procedure «2 out of 3».

С 2017 года количество ежегодно выводимых на орбиту сверхмалых и малых космических аппаратов (МКА) массой менее 500 кг превысило число более тяжелых КА. Реализуемые в настоящее проекты орбитальных группировок (ОГ) с десятками и даже тысячами МКА позволяют обеспечивать доступ к заданным участкам поверхности Земли вплоть до реального масштаба времени. При этом стоимость создания МКА производители обещают снизить за счёт конвейерного производства на два порядка при неизменном уровне цен на выведение одного килограмма полезного груза, т.е. стоимость создания МКА станет ниже стоимость их выведения. В рамках выполненных исследований получены зависимости между требуемыми показателями качества дистанционного зондирования Земли при мониторинге чрезвычайных ситуаций и массогабаритными характеристиками инфракрасной оптико-электронной аппаратуры (ОЭА). Представленные результаты предназначены для решения задачи обоснования оптимального облика МКА при заданных требованиях к качеству его функционирования.

Since 2017 the quantity put annually to orbit midget and the small spacecrafts exceeded number of KA weighing more than 500 kg. The projects of the orbital groups realized in the present allow to provide with about tens and even thousands of SS access to the set sites of the Earth’s surface up to real time scale. At the same time producers promise to reduce the cost of creation of SS due to conveyor production for two orders at the invariable level of prices for removal of one kilogram of a payload, i.e. cost of removal of SS will exceed the cost of their creation. Within the executed researches dependences between the required indicators of quality of remote sensing of Earth when monitoring emergency situations are received and massdimensional characteristics of the infrared optical-electronic equipment. The presented results are intended for the solution of a problem of justifi cation of optimum shape of SS at the set requirements to quality of its functioning.

Предложенная газоаналитическая схема позволяет создать аналитическую информационную сеть мониторинга среды по компонентам ракетных топлив различного состава.

The own work considers the method of integrated analytical control of asymmetric 1-2-methylhydrazine in air, soil, water and aqueous solutions. A circuitry and analytical solution is proposed, which constitutes the analytical basis of gas analyzers, which make it possible to study the environment, both by local pollution and distributed over vast territories. The absence of a procedure for preparing samples for analysis signifi cantly increases the effectiveness of control and the possibility of field application. The proposed gas analytical scheme allows you to create an analytical information network for monitoring the environment for the components of rocket fuels of various compositions.
CURRENT SELF-INDUCTION AND POTENTIAL WELL ON SUPERCONDUCTING RINGS
Authors: МЕНДЕ Ф.Ф.
Published: September 2024

В работе рассмотрено новое физическое явление потенциальная яма на сверхпроводящих кольцах. Это явление указывает на то, что два сверхпроводящих кольца разного диаметра, в которых заморожены потоки, могут находиться друг по отношению к другу в потенциальной яме, когда их сближение или удаление приводит к возникновению возвращающей силы. Расстояние между кольцами, которое определяет такую яму, соответствует минимуму потенциальной энергии системы связанных колец. Это явление может найти практическое применение для создания эталонов силы и высокочувствительных приборов для ее измерения, таких как гравиметры и акселерометры.

A new physical phenomenon is considered in the work of a potential well on superconducting rings. This phenomenon indicates that two superconducting rings of different diameters, in which the fl ows are frozen, can be located relative to each other in the potential well, when their approach or removal leads to the appearance of a restoring force. The distance between the rings that determines such a pit corresponds to the minimum potential energy of the system of coupled rings. This phenomenon can fi nd practical application for creating power standards and highly sensitive instruments for measuring it, such as gravimeters and accelerometers.
THE FORECAST OF THE SOLAR MAGNETIC ACTIVITY BASED ON MODIFIED ALTERNATING WOLF NUMBERS
Authors: ЛАПТУХОВ А.И. , ЛАПТУХОВ В.А.
Published: September 2024

Для описания магнитной активности Солнца предлагается вместо чисел Вольфа W(t) использовать знакопеременный параметр, в котором знак перед корнем изменяется на противоположный в момент минимума солнечной активности. Показаны преимущества использования параметра V перед W=V2. В спектре функции V(t) среди основных девяти частот wk обнаружено 17 резонансов вида wk+wn=wi+wj или wk+wn=wj, выполняющихся с точностью 98,5…100 %. Оказалось, что периоды Pk=2n/wk основных гармоник укладываются целое число раз на интервале времени T = 130 лет. Сделан прогноз солнечной активности и показано, что в ближайшие несколько циклов она будет низкой и такой, какой была 130 лет назад. Такой же результат получен авторами ранее принципиально другим методом, что указывает как на правильность этих прогнозов, так и на эффективность используемых методик прогноза.

To describe the magnetic activity of the sun, it is proposed to use the alternating parameter, instead of Wolff numbers W(t), in which the sign before the root changes to the opposite at the moment of minimum solar activity. The advantages of using the parameter V before W=V2 are shown. In the spectrum of the function V(t) 17 resonances of the form wk+wn=wi+wj or wk+wn=wj, which are satisfi ed with an accuracy of 98,5…100 %, are found among the main nine frequencies wk. It turned out that the periods Pk=2n/wk of the fundamental harmonics fit an integer number of times in the time interval T=130 years. A forecast of solar activity has been made and it is shown that in the next few cycles it will be low and such as it was 130 years ago. The same result was obtained earlier by the authors in a fundamentally different way, which indicates both the correctness of these forecasts and the effectiveness of the forecasting methods used.

В статье авторами обоснован выбор формы волны из числа регистрируемых экспериментально и предложено принимать эту форму по соотношению основных ее параметров неизменной на узком участке ее распространения в зоне технологического дробления породы взрывом. Математическое описание форм волны представлено в виде трехкусочной функции, с использованием которой определяются напряжения, деформации и энергия, проходящая через любую цилиндрическую поверхность в зоне действия волны. Авторами предложен оригинальный метод определения энергии в кольцевом объеме за все время прохождения волны как разница энергий, проходящих через две соседствующие кольцевые поверхности. С использованием разработанной авторами компьютерной программы рассчитаны матрицы распределения плотности энергии волны напряжений в отбиваемом объеме и построены цветные фотопланограммы распределения плотности энергии.

The mathematical description of the forms waves is presented in the form of a three-piece function, using which the stresses, deformations and energy passing through any cylindrical surface in the wavelength range are determined. The authors propose an original method for determining the energy in the ring volume for the entire time of the wave as the difference of energies passing through two adjacent ring surfaces. Using the authors developed software calculated a matrix of distribution of energy density of a wave of pressure in beats volumes and built colored photoplanogram distribution of energy density.

Рассматривается задача о фильтрационно-волновом поле в слоисто-неоднородной ортотропной среде в предположении преобладания вертикальной проницаемости в пропластках, окружающих нефтяной коллектор. Представлены решения, описывающие пространственно-временные распределения в ближней к источнику возмущения зоне пропластков. Приведены аналитические зависимости коэффициента поглощения, волнового числа и фазовой скорости от частоты воздействия на призабойную зону пласта-коллектора. В результате вычислительного эксперимента выявлены физические свойства пористой среды и насыщающего флюида, определяющие фазовую скорость волны давления при импульсно-волновой обработке кольматированной зоны.

The problem of the filtration-wave field in a layered-inhomogeneous orthotropic medium is considered under the assumption of the predominance of vertical permeability in the layers sur-rounding the oil reservoir. Solutions are presented that describe the spatial-temporal distributions in the near-source area of the disturbance. Analytical dependences of the absorption coefficient, wave number, and phase velocity on the frequency of impact on the bottom-hole zone of the res-ervoir are presented. As a result of the computational experiment, the physical properties of the porous medium and the saturating fluid that determine the phase velocity of the pressure wave during pulse-wave processing of the colmated zone are revealed.

Вычислительные эксперименты на основе задачи о релаксационном поле давления в слоисто-неоднородном пласте при фильтрации углеводородов с учётом гидродинамического влияния скважины позволили уточнить вклад физических процессов. Путём сопоставления решений задач с учётом и без учёта влияния скважины уточнён вклад релаксационных процессов и характерное время релаксации. Показано, что при малых временах вклад скважины возрастает с увеличением времени, затем он достигает максимума и при больших временах поля давления с учётом и без учёта влияния скважины сближаются. Установлены параметры, определяющие процессы релаксации фильтрационного поля давления.

Computational experiments based on the problem of the relaxation field of pressure in a layered heterogeneous reservoir during filtration of hydrocarbons, taking into account the hydrodynamic effect of the well, made it possible to clarify the contribution of physical processes. By comparing the solutions of problems with and without taking into account the effect of the well, the contribution of relaxation processes and the characteristic relaxation time are refined. It is shown that at small times the well contribution increases with time, then it reaches a maximum, and at large times, the pressure field, with and without the infl uence of the well, converges. The parameters determining the processes of relaxation of the filtration pressure field are established.
