Published: September 2024

In recent times, surface water has been seen not to be a good source of domestic water because of impurities from physical, biological and chemical contaminants. The use of geophysical techniques for groundwater exploration and water quality evaluations has increased over the past few years due to the rapid advances in computer software and associated numerical modeling solutions. A 2D electrical resistivity tomographic method was adopted in this study using the Werner electrode arrangement in determining the variation of subsurface resistivity distribution in Etim Ekpo, southern Nigeria. Ten soundings were carried out in the area. The RES2DINV software was used to transform the measured ERT data to an approximate picture of the subsurface resistivity distribution and geometry of the subsurface features. The resistivity values in the area for layer 1(top soil) range from 34.60 Ωm to 2311Ωm while the thickness ranges from 0 to 12 m. For layer 2 (lateritic sand), the resistivity values range from 213 Ωm to 3982 Ωm while the thickness ranges from 5 to 20 m. The resistivity values in the area for layer 3(coarse grained sand) range from 1237 Ω m to 6964 Ω m while the thickness ranges from 17 to 57 m. Three geo-electric layers were delineated (top soil, lateritic sand and the coarse grained sand). This study shows that the groundwater potential within the area is of economic volume.

Published: September 2024

This study was conducted to evaluate soil samples and the distribution of soil arthropods at the University of Uyo. The following  physicochemical parameters and inorganic loads of the soil were measured for arthropod species obtained with the Berlese-Tullgren  extractor: pH, temperature (ºC), electrical conductivity (mg/L), BOD (mg/L), Chloride (mg/L), Nitrate (mg/L), Phosphate (mg/L), Sulphate  (mg/L) and Nitrite (mg/L). Soil arthropod samples were collected from four (4) sampling sites: the Faculties of Science, Agriculture,  Engineering, and Postgraduate School (PGS) using pitfall trap and Berlese-Tullgren extraction funnel techniques. The results of the soil  physicochemical parameters and inorganic contents revealed that variables differed significantly between sampling sites at p < 0.05. Fifty- two species of soil-dwelling arthropods were collected and classified into four (4) classes; Insecta, Hexapoda, Arachnida, and Diplopoda,  fourteen orders with 2310 individual species. The number of individuals of Hymenoptera 989 (42.81%), Coleoptera 455 (19.70%),  Orthoptera 422 (18.27%), Polydesmida 94 (4.07%), Arachnida 92 (3.98%) and Hemiptera 71 (3.07%) was widely collected across both seasons, using pitfall and Berlese-Tullgren extractor funnel method. The dominant species were Formica sp. (390; 16.88%), Camponotus  vagus (313; 13.55%), and Teleogryllus emma (296; 12.81%). The collection of soil arthropods during the wet season (1673; 72.42%) had a  higher abundance than the dry season (637; 27.58%) across all sampling sites. It was evidence that the pitfall trap expressed more  effectiveness in the collection of soil-dwelling arthropods (1693; 73.29%) than the Berlese-Tullgren extractor funnel method (617: 26.71%).  Results of the soil samples show that the soil's physicochemical parameters and inorganic loads fell within the Environmental  Protection Agency (EPA) recommended range. The composition, individual, and relative abundance recorded in this study suggest that  the University of Uyo has high soil arthropod species diversity, more research should be carried out to close the gap in the species of this  wonderful group in the University.

Evaluation of reservoir rocks in Gabo Field, Niger Delta for CO2 storage and retention
Authors: Usen W. S. , Akpabio I. O.
Published: September 2024

The study was conducted to evaluate the reservoir rocks for carbon storage and retention using seismic and well log data. A multidimensional sequence stratigraphic framework was constructed, estimated the spatial and lateral continuity of reservoir sands, deduced petrophysical properties of offshore sands and interpreted gross depositional settings and processes. Well-to-seismic tie analysis was performed to verify the accuracy of seismic data, while well correction analysis was carried out to adjust well data for errors and inconsistencies. Fault and horizon interpretations were conducted, revealing regional faults, major counter-regional faults, and reverse faults. A comprehensive 3D analysis was performed to assess the facies composition, porosity distribution, and water saturation in the field reservoirs. Sand facies dominated the reservoir, indicating favourable conditions with high porosity and permeability. The results significantly showed the reservoir's geological characteristics, fluid dynamics and potentials for hydrocarbon accumulation, carbon storage and retention. Sands A, B, C and D were found to exhibit favourable characteristics for CO2 storage.
A Generalization of Reisz characterization of absolute continuity in Lp [a,b]−spaces
Authors: Udo-Utun X. , Johnson U. , Edet U.
Published: September 2024

We initiate studies of a new classical characterization of absolute continuity which promises to be invaluable in studies and further generalizations of nonclassical characterizations of absolute continuity in diversely more general function spaces. Our main objective is showing that our newer characterization for absolute continuity includes Riesz characterization in Lp−spaces  (p>1) by allowing the situation p≥ 1. Our method also enriches studies of connection between absolute continuity and rapidly Cauchy sequences.
On Symmetry in Physical Phenomena, Symmetry of an Electric Field and of a Magnetic Field
Authors: Curie Pierre , Ziółkowski (translation and commentary) Andrzej
Published: September 2024

In this work, the classical concept of symmetry limited to geometric objects (figures and solids), which originated from ancient Greece, has been extended to allow for symmetry studies in other types of objects.
By introducing the concepts of limiting point groups and kinematic elements characteristic for a studied object, it was determined what types of symmetries are exhibited by an electric field and a magnetic field. It was established that in order for a phenomenon to occur, a characteristic symmetry of a medium must be consistent with the characteristic symmetry of the phenomenon occurring in it. It was also determined that the symmetry elements of the causes must be found in the symmetry of their effects.

Was Copernicus an Astrologer? From the Perspective of a Historian of Astrology
Authors: Konarska-Zimnicka Sylwia
Published: September 2024

Nicolaus Copernicus’s achievements in the field of astronomy are widely known and undisputed, but few people know that he also studied astrology – in his time recognised as a science and a subject of academic lectures. Evidence of this activity, though scarce, is preserved in the margins of one of the popular astrological treatises of the 15th and 16th centuries, which was owned by Nicolaus Copernicus. Thanks to these marginal notes it is possible to undertake a consideration of the scale and reasons for the involvement of the astronomer in the exploration of astrology.
The Reception of Neptune’s Discovery in British and American Protestant Theology
Authors: Roskal Zenon , Rodzeń Jacek
Published: September 2024

The discovery of the planet Neptune in 1846, first theoretically and then observationally, was a 19th-century event that went beyond the interests of the narrow group of astronomers of the time. Indeed, the significance of this event is still a subject of interest among historians and philosophers of science. During the period discussed, natural theology played a special cognitive and social role, forming the basis for arguments based on the new knowledge of nature. This article discusses how the discovery of Neptune was received among the community of 19th-century British and American Protestant theologians, who were always open to scientific research and discoveries.
Reflections on the Importance of the Leonhardi Euleri Opera Omnia, Volume IV A (2016) and Volume VIII (2018)
Authors: Domoradzki Stanisław , Zarichnyi Mykhailo
Published: September 2024

The article is devoted to two volumes of Leonhard Euler’s correspondence with mathematicians and other scientists.
The first of these volumes (in two parts) is devoted to correspondence with Christian Goldbach. We consider selected topics from this correspondence reflecting various branches of mathematics and demonstrate, where possible, the connection of the ideas and results presented there with modern mathematical research.
The second of these two volumes contains Euler’s correspondence with scholars associated with the University of Halle. These letters, with a small exception, have less mathematical content, but allow to create an impression of academic life at that time.
Zwicky as a Pluralist
Authors: Heiblum Robles Alan
Published: September 2024

Fritz Zwicky is best known to the general public for his scientific work. His methodological views are less known and some of his philosophical ideas did not receive favorable reviews. In other reading, however, Zwicky’s principle of flexibility of scientific truth, which asserts that no scientific statement can be absolute but rather subject to refinements or expansions, shows it as a contribution to epistemic pluralism.

In connection with the beginning transition of mass-produced battery electric vehicle (BEV) powertrains from single-gear gearboxes to specially configured automatic transmissions (AT), the number of publications devoted to justification and research of their architecture, as well as optimization of applied design solutions, is rapidly increasing. A large number of publications focus on dual-clutch AT (i. e. DCT) with two clutches (or frictions) in the first stage application. A clear recent trend in their subject matter is a shift of interest in DCT control, especially in transient automatic gear shifting with joint control of the motorgenerator (MG) and frictions in an integrated powertrain. It is shown that smoothness of shifting here is of no less importance than in classical AT, not only because of shift shocks, which deteriorate comfort, but also because of the possibility of excitation of oscillating modes in the electric drive. The paper analyzes several published variants of a strategy for controlling such shifting processes and their computer and physical implementation. We believe that, given the lack of Russian-language materials on this subject, this information is published for the first time.

New applications and modern methods are described for manufacturing gears made of polymer composites using additive (3D printing) and microelectronics technologies (burning and rapid prototyping from photopolymers). The methods of calculation of the load-bearing capacity, wear and durability of polymer and metal-polymer gears (straight and helical spur, bevel) are considered which are based on methodology of composite mechanics and phenomenological model of fatigue wear during sliding friction. The application of analytical solutions for fast parametric analysis of the stress-strain state of gears is shown, as well as the use of their spatial discretization by finite and boundary elements, taking into account the real geometry of engagement. The use of gears in drives of microelectromechanical systems and the specifics of calculations due to the strengthening of adhesive interaction in tooth contact of miniature gears are considered. The features of the deformation of polymer composites, as structurally inhomogeneous and physically nonlinear materials are noted, which should be taken into account when determining the kinematic accuracy of gears. In this regard, the possibilities of a three-level method are discussed for designing gears made of dispersion-filled polymer composites according to the criteria of strength, deformability and wear resistance. The proposed method provides an iterative procedure for optimizing the material composition and gear parameters, each stage of which includes analytical modeling of the dispersion-reinforced composites used (microlevel), computational and experimental verification of micromechanical models on test samples (mesolevel) and numerical analysis of the stress-strain state of gears by finite element method (macrolevel).
Peter I at ceremonies in the Peter and Paul and Trinity Cathedrals (St. Petersburg)
Authors: Славнитский Н.Р.
Published: September 2024

В работе предполагается рассмотреть церковные церемонии в С.‑ Петербурге, на которых присутствовал Петр I. Первоначально они проходили в Петропавловском соборе, а после 1712 г. (когда началась перестройка собора) — в Троицком соборе. Основная цель статьи — выделить основные праздники того времени, проследить развитие их церемониала, а также рассмотреть поведение царя на этих церемониях. В тех случаях, когда Петр I находился в С.‑ Петербурге, он неизменно присутствовал на церковных церемониях, которые являлись частью викториальных, церковных, а также светских праздников. К первым относились церемонии празднования побед российских войск в сражениях Северной войны, а также годовщины наиболее значимых викторий (под Полтавой, Лесной, Гангутом). Основными религиозными праздниками были Рождество, Крещение и Пасха, а из светских наиболее значимым в петровское царствование стало празднование нового года 1 января. Из записок иностранных дипломатов того времени известно, что Петр I не только присутствовал на указанных церемониях, но и сам принимал в них активное участие.

The work is supposed to consider church ceremonies in St. Petersburg, which were attended by Peter I. Initially, they took place in the Peter and Paul Cathedral, and after 1712 (when the reconstruction of the cathedral began) — in the Trinity Cathedral. The main purpose of the article is to highlight the main holidays, trace the development of the ceremonial, and also consider the behavior of the king at these ceremonies. In those cases when Peter I was in St. Petersburg, he invariably attended church ceremonies, which were part of the victorious, church, and also secular holidays. The first included the ceremonies of the victories of Russian troops in the battles of the Northern War, as well as the anniversaries of the most significant victories (near Poltava, Lesnaya, Gangut). Religious holidays were annual — Christmas, Epiphany and Easter. And of the secular, the most significant in his reign was the celebration of the new year on January 1. Moreover, it is known from the notes of foreign diplomats of that time that Peter I not only attended these ceremonies, but also took an active part in them himself.
The Anglican-Orthodox Contacts from Peter I to Alexander II (political aspect)
Authors: Смирнова И.Ю.
Published: September 2024

В статье представлен обзор основных этапов развития англикано-православного сближения, начавшегося в эпоху Петра I и достигшего апогея во второй половине XIX в., когда в англиканских епископальных Церквах Англии и Северо-Американских Соединенных Штатов рассматривалась возможность воссоединения с Православной Греко-Восточной Церковью. Особое внимание уделено внешнеполитическому аспекту англикано-православного диалога в XIX в., когда развитие миссионерской деятельности англиканских Церквей Англии и Северной Америки в странах Ближнего Востока осуществлялось в политических интересах Великобритании и США. Зарубежная миссионерская деятельность англиканских Церквей на протяжении всего XIX в. ставит под сомнение исключительно церковный характер англикано-православного диалога, получившего неоднозначную оценку в российских синодальных и дипломатических кругах.

The article provides an overview of the main stages in the development of the issue of Anglican-Orthodox rapprochement, which began in the era of Peter I and reached its apogee in the 2nd half of the 19th century, when the Anglican Episcopal Churches of England and the North American United States considered the possibility of reunification with the Orthodox Greco-Eastern Church. Particular attention is paid to the foreign policy aspect of the Anglican-Orthodox dialogue in the 19th century, when the development of the missionary activity of the Anglican Churches of England and North America in the countries of the Middle East was carried out in the political interests of Great Britain and the United States. Foreign missionary activity of the Anglican Churches throughout the 19th century casts doubt on the purely ecclesiastical nature of the Anglican-Orthodox dialogue, which received a mixed assessment in Russian synodal and diplomatic circles.

Epigraphical Evidences of Veneration of St. Serapion, Metropolitan Krutitsky, Sarsky and Podonsky in the Trinity Makariev Kalyazin Monastery (18th–19th Centuries)
Authors: Авдеев А.Г.
Published: September 2024

В статье анализируется комплекс эпиграфических памятников Троицкого Макарьева Калязина монастыря, сложившийся в последней четверти XVIII–XIX вв. и отразивший основные этапы формирования местного почитания Серапиона, митрополита Крутицкого, Сарского и Подонского. Святитель был уроженцем города Кашина, монашеский постриг принял в Калязине монастыре, здесь же и скончался на покое 2 мая 1653 г. Почитание митрополита Серапиона началось в 1779 г. Основу агиографического комплекса составили эпитафии CIR4049 и CIR4050, в начале XIX в. комплекс пополнила плита с «историческим портретом» святителя (CIR4108), еще позднее — надгробная надпись CIR4109.

The paper analyzes the epigraphic monuments of the Trinity Makariev Kalyazin monastery of the last quarter of the 18th–19th centuries, reflecting the main formation stages of local veneration of Serapion, Metropolitan Krutitsky, Sarsky and Podonsky. St. Serapion was a native of the town of Kashin. In the Kalyazin monastery, he took monastic vows, retired, and died on May 2, 1653. Veneration of Metropolitan Serapion began in 1779 after the miraculous healing of a merchant from St. Petersburg. The basis of the hagiographic complex included the epitaphs CIR4049 and CIR4050. At the beginning of the 19th century the complex was supplemented by a plate with a “historical portrait” of the saint (CIR4108), and later — by a tombstone inscription CIR4109.

The aim of writing this article is to deepen insight related to Reconstruction of the Ius Constituendum of Cyber Notary in E-GMS as Relaas Acta. This research uses a normative legal research method in the form of a statutory approach. During the COVID-19 pandemic, Indonesia first used E-GMS which was adapted to Cyber Notary. However, various problems arose during its implementation. The research results show that there is legal uncertainty regarding cyber notary regulations in Indonesia regarding E-GMS where the deed is drawn up by a notary as a relaas acta, so that a draft legislation is needed as the legal basis for cyber notaries in the future to guarantee the validity of an authentic deed.
