Lev S. Vygotsky's cultural-historical theory and Soviet psychology of religion: did they overlap?
Authors: Dvoinin Alexey
Published: June 2024

The paper examines the role played by one of the basic Marxist psychological theories in developing Soviet psychology of religion. An attempt is made to find out whether the cultural-historical theory of Lev S. Vygotsky overlapped with this field of knowledge. The author reconstructs a general picture of the objective relationship between cultural-historical theory and Soviet psychology of religion. The nature of this relationship has been identified in four key dimensions: the problems studied, research methodology, academic communities, and academic institutions. The first two dimensions relate to the cognitive aspect of science, the last two – to the social aspect. It is noted that Lev S. Vygotsky’s research did not touch on specific issues of the psychology of religion. The exception is his reference to the problem of magical thinking. Other cultural-historical theorists also did not focus on religious issues. Only a few rare examples of religious life can be found in their works. At the same time, it is argued that the works of cultural-historical theorists were cited by Soviet researchers of religion. However, neither the conceptual ideas of Lev S. Vygotsky (i.e., semiotic mediation, lower and higher mental functions, stages of children’s mental development and age-related new mental structures, etc.) nor his methodological innovations were ever systematically applied and elaborated in Soviet psychology of religion. The paper also finds no trace of an overlap between cultural-historical theory and Soviet psychology of religion in academic communities and institutions, except for the participation of Lev S. Vygotsky and Alexander R. Luria in the discussion of Lucien Lévi-Bruhl’s theory of prelogical thinking, which took place in the 1924-1930s. The article offers explanations for the research results described. Presumably, it was the formation of a negative attitude of science towards religion in the Soviet period under the political and ideological influences that made the meaningful overlap between Lev S. Vygotsky’s cultural-historical theory and the Soviet psychology of religion problematic.
“The Power of the Keys” and confession: pastoral power in the “Six readings on the Sacrament of Penance in its history” by revd. Valentin Sventzitsky
Authors: Yachmenik Vyacheslav
Published: June 2024

This article focuses on the concept of pastoral power as presented by Fr Valentine Sventzitsky in his text “Six Readings on the Sacrament of Penance in its History”, which is significant for contemporary Russian Orthodoxy. Opposing the practice of general confession in the 1920s, he contrasts it with private confession, basing his arguments on pre-revolutionary studies of penitential practices and priesthood. At the same time, in Sventzitsky’s text, academic theses undergo a significant transformation in connection with his historiosophic and religious-philosophical ideas. First of all, he uses in this context the theory of the gradual unfolding of the Church's self-consciousness in history and projects this theory onto the theological reflection on the development of the forms of the Sacraments. In the same vein, in relation to ecclesiastical practices, he applies the theory of the historical differentiation in the Church of good and evil. In this context we analyze Sventzitsky's ideas about the secularization of the Church, to which he contrasts the active spiritualization of all life and formulates this call in the idea of a monastery in the world. The article shows what place the priest has in the formation of the monastery in the world. Against this background, the analysis of representations of pastoral power both in the “Readings” and in other texts by Sventzitsky, and correlating them with the sources on which he relies, allows us to highlight his thesis about the transformation of this type of power in history. The author of the Readings identifies three characteristic periods in which pastoral power changed from its public dimension in the ancient Church, communal — in Byzantine monasteries and Russian parish churches, and, finally, personal-psychological — in the context of the Soviet period. These three types of pastoral power are analyzed by Sventzitsky in connection with the transformation in historical perspective of the forms of confession, the continuity of the “power of the keys” in the Church, and the actualization of obedience in church life. From this perspective, Sventzitsky offers a theological justification for the established practice of confession, which he constructs as a bricolage of Russian academic theology and philosophy.
Conceptual and terminological aspect of the practice of revelation of thoughts in the tradition of Egyptian and Palestinian monasticism of the 4th — 7th centuries
Authors: Fadeev Alexander
Published: June 2024

The article analyzes the original terminology of the patristic writings of Egyptian and Palestinian monasticism of the 4th - 7th centuries, which is found when mentioning the practice of revelation of thoughts as an important pastoral-ascetic activity and a form of spiritual leadership in the monastic tradition of this period. The author identifies the main terms related to this area, analyzes the context of their use and various semantic shades that reflect the corresponding forms, conditions and characteristics of this activity. Modern patrolologists strictly distinguish the practice of revealing thoughts from confession, which in ancient times was carried out in all forms of monastic life: hermitage, semi-hermitage, community and laura. At the same time, the most ancient sources do not always reflect this difference, their external forms and ideological content. Another equally important question remains not entirely clear: how the great fathers of ancient Eastern monasticism understood this saving remedy, whether for them there was a division between confession and revelation of thoughts as between two different actions of repentance, and if so, what appeared for them clear criteria for such division. The sources for the study were the most famous and significant works of monastic writing in the tradition of Egypt and Palestine in the 4th - 7th centuries, as the period of formation, development and greatest flowering of monasticism, and at the same time its ascetic and pastoral theology. Some manuscripts of individual sources were also used as sources, including the most ancient ones, reflecting the understanding of the practice being studied in the minds of scribes belonging to various manuscript traditions - Greek, Latin and Coptic. The subject of study are terms denoting revelation (of hidden thoughts, sinful falls committed in secret), revelation (of oneself, one’s emotional experiences, demonic temptations, etc.), confession (of sins, a passionate disposition of the soul and its destructive consequences), etc.
Features of the singing at the contemporary orthodox service in China
Authors: Zheng Yutsin
Published: June 2024

Analyzes the musical material used for worship in Orthodox churches in China. The author considers the conservative tendency, which is followed by Nina Starostina, and the renewal tendency, which is worked on by Nikolay Lebedev. The specifics of N. Starostina's work on new vowels, based on the well-known Chinese songs and means of musical expression, used by the composer in her compositions on canonical liturgical texts are outlined.The article compares the interpretation of substantive aspects of the canonical osmoglavya by Archpriest Boris Nikolaev and the tunes underlying the "Chinese Glas" by Nina Borisovna Starostina, a Moscow composer and researcher of guqin playing who has lived in China and is deeply familiar with the musical culture of China. The emphasis is placed on the means of musical expression peculiar to Chinese musical poetics used in Nina Starostina's works on canonical liturgical texts, as well as on the traditional stylistics of the works of Nikolai Lebedev, an adherent of the Holy Trinity Masterpieces school. It is hypothetically suggested that there is a great difference between these "extremes," but that these are two cardinally opposite paths, outlined today, that the choral tradition in China might follow.As a result, the following varieties of chants are identified in Chinese Orthodox churches: retexts of traditional vowels and chants of later origin (Greek, Yaroslavl, etc.) without modification; retexts of traditional vowels and chants of later origin adapted because of the difference in phonetics of the Chinese and Slavonic languages, and in order to bring them closer to the angelic ones. The following are some of the chants that can be heard in Chinese Orthodox churches: retexts of traditional vowels and chants of later origin, adapted to suit the phonetics of the Chinese and Slavonic languages and to bring them closer to the angemite pentatonic keys of China; new chants composed in the Chinese style to canonical liturgical texts and chants composed in the tradition of Rask spiritual music, and also taken from chant books that are widely available in Orthodox parishes.
The assembly of saints of the land of Krasnoyarsk. The issue of iconography
Authors: Kopersak Elena
Published: June 2024

At the turn of the XX-XXI centuries the list of saints of the Orthodox Church has been replenished with an impressive number of names of new martyrs and confessors who suffered during the Soviet era. In this regard, such a phenomenon as the "Synaxes of the Saints of the Diocese" has spread widely. As you know, each Catholic memory of saints established in the Church involves veneration, therefore, new celebrations appear dedicated to the Synaxes of the ascetics of the Russian Church in various regions of the country. And this means that right now new iconographic images of the New Martyrs and locally venerated saints are being born. Modern icon painters are actively engaged in the creation of icons and temple paintings that glorify the new saints and tell about the torment and executions to which they were subjected. In 2015, the Synaxe of Saints of the Krasnoyarsk Metropolis was established. To date, only three icons dedicated to the Synaxe of the Krasnoyarsk Saints are known. The article for the first time examines the process of adding the iconography of the Synaxe of the Krasnoyarsk Saints within the framework of church canonical art, defines its historical and partly theological aspects, analyzes compositional and stylistic devices, shows the role of symbolism in revealing the image, determines the uniqueness of the figurative solution, identifies some problems and trends in the development of modern church art. painting in Krasnoyarsk. The author for the first time introduces new names of Krasnoyarsk masters and their works into scientific circulation.
Small cycles of chants in the all-night vigil by S. V. Rachmaninoff (Op. 37): image-related and thematic content and features of the composition
Authors: Kovalev Andrey
Published: June 2024

The article is devoted to the problem of the organization of the structure of the choral cycle of the All-Night Vigil of Op. 37 S. V. Rachmaninov. As one of the most important elements of its compositional construction, the interaction of four small cycles is considered here, each of which is characterized by a common figurative-thematic content and means of composition. These are: 1. The cycle of Old Testament and New Testament Hymns of Vespers; 2. The Cycle of Theotokos Hymns; 3. The cycle of hymns of praise; 4. The cycle of Sunday Hymns. Small cycles include both alternate chants following each other, and interconnected at a distance.The purpose is to identify the features of the author's musical reading of the canonical text of the service, the placement of artistic accents emphasizing certain motives of the Holy Scripture. The methodology of the work is based on an interdisciplinary approach to the study of spiritual and musical works, using information from liturgics, religious philosophy, as well as scientific categories of Russian musicology.Conclusion. The organization of the structure of the choral cycle of the All-Night Vigil Op. 37 by S. V. Rachmaninov testifies to the versatility, versatility of this composition, located between the liturgical and extra-liturgical genre poles, and its architectonics is characterized by the interaction of the four small cycles included in it. Along with the generality of the figurative and thematic content, the formation of small cycles is due to the peculiarities of the composition at the level of melody, shaping, texture, ladoharmonic and tonal plan.
НАЦІОНАЛЬНІ ІНТЕРЕСИ УКРАЇНИ В УМОВАХ ФРАГМЕНТАЦІЇ СВІТОВОЇ ЕКОНОМІКИ
Authors: ПЛОТНІКОВ Олексій
Published: June 2024

Розглянуто питання врахування національних інтересів України в умовах  фрагментації світової економіки. Показано, що фрагментація є одним з наслідків російської збройної агресії проти України і здатна призвести до поділу світу на геополітичні блоки з відповідними технічними стандартами, системами платежів і резервними валютами.
Визначено актуальні напрями подальшого розвитку держави в умовах фрагментації, з-поміж яких виокремлено такі: орієнтація України на оптимальну модель розвитку провідних країн світу; підтримка України з боку урядів країн світу і міжнародних фінансових організацій; санкційна політика проти країни-агресорки та інші обмежувальні заходи в повоєнний період; різного роду ризики світової економіки тощо.
Фрагментація світової економіки дозволяє визначити групи країн світу, здатних слугувати орієнтиром для подальшого економічного і політичного розвитку України. Ідеться як про перспективи членства в ЄС, так і про більш широкі напрями партнерства з США, Великою Британією та іншими країнами світу. Наголошено, що фрагментація фактично відсікла окремі країни, у першу чергу ті, що пов’язані з країною-агресоркою.
Крім чинника орієнтованості на ЄС критерії вибору моделі розвитку України, з урахуванням її національних інтересів, повинні полягати в стійкості й перспективності розвитку. 
Зроблено висновки стосовно врахування національних інтересів України в умовах фрагментації світової економіки. Так, взаємовідносини України з урядами іноземних  країн і міжнародними фінансовими організаціями слід вибудовувати на поточних реаліях національної економіки. Для цього потрібна більш широка визначеність, яка б включала середньо- і довгострокові перспективи, а співпраця в цьому напрямі має базуватися на адекватному розумінні розвитку країни. Необхідність проведення реформ в Україні одночасно з процесом повоєнної відбудови розцінюється як важлива запорука успішності реформ та їх адекватності вимогам сучасного світу.

Screening Accuracy of BMI for Adiposity Among 8- to 19-Year-Olds
Authors: Freedman David S. , Zemel Babette S. , Dietz William H. , Daymont Carrie
Published: June 2024

BACKGROUND AND OBJECTIVES

Although the limitations of BMI have long been recognized, there are recent concerns that it is not a good screening tool for adiposity. We therefore examined the cross-sectional relation of BMI to adiposity among 6923 8- to 19-year-olds in the National Health and Nutrition Survey from 2011 through 2018.

METHODS

Participants were scanned with dual-energy x-ray absorptiometry. Adiposity was expressed as fat mass index (FMI, fat mass kg ÷ m2) and percentage of body fat (%fat). Lean mass was expressed as lean mass index (LMI, lean mass ÷ m2). Regression models and 2 × 2 tables were used to assess the relation of BMI to FMI, %fat, and LMI.

RESULTS

Age and BMI accounted (R2) for 90% to 94% of the variability of FMI and LMI in each sex. Associations with %fat were weaker (R2s ∼0.70). We also examined the screening abilities of a BMI ≥ Centers for Disease Control and Prevention 95th percentile for high levels of adiposity and LMI. Cut points were chosen so that prevalences of high values of these variables would be similar to that for high BMI. Of participants with a high BMI, 88% had a high FMI, and 76% had a high %fat. Participants with a high BMI were 29 times more likely to have a high FMI than those with lower BMIs; comparable relative risks were 12 for high %fat and 14 for high LMI.

CONCLUSIONS

Despite its limitations, a high BMI is a very good screening tool for identifying children and adolescents with elevated adiposity.

Published: June 2024

Bioactive peptides are promising functional ingredients. Due to its high protein content, snakehead fish (Channa striata) extract (SHFE) is one of the suitable parent proteins for bioactive peptides. This study aimed to investigate the production of SHFE-based antioxidative peptides in a conventional batch and continuous system facilitated by an enzymatic membrane reactor (EMR). The effects of different proteases (Alcalase, Neutrase), substrate concentrations, and enzyme-to-substrate ratios were investigated in the batch process. Continuous hydrolysis was then performed under the optimum conditions obtained from the batch process. The optimum conditions based on the antioxidant capacity measured by DPPH and FRAP assays were employing Alcalase with a substrate concentration [S] of 3% (w/v) and an enzyme-to-substrate ratio [E]/[S] of 10% (w/w). Continuous operation was shown to have been performed over a prolonged period, based on the calculated fouling rate. Furthermore, filtration of the resulting permeate with a smaller membrane pore size (2-kDa) increased the antioxidant capacity. This study is expected to increase the production of functional ingredients in snakehead fish.

Authors: Jóźwik Katarzyna
Published: June 2024

Despite the large number of publications about the figure and activities of Father Jerzy Popiełuszko, there is a shortage of reliable academic studies analysing the documentation concerning the priest produced by the communist apparatus of repression. The aim of the present text is to present the reports of secret collaborators focused on Father Popieluszko and an extensive historical analysis of their activities. For the purposes of this text, the work files and personal files of three secret collaborators with pseudonyms were analysed: „Jankowski”, „Kustosz”, „Tarcza/Miecz”. The personalities of these persons and the file references were previously known and mentioned, mainly by journalists, but no solid scholarly work, apart from the files of tw „Jankowski”, has been done so far. The records of tw „Janusz” and the steelworkers „Bogdan”, „Uczciwy” and „Fredek”, which have not been mentioned so far, were also discussed. The basic sources for investigating this issue are the materials produced by the Ministry of the Internal Affairs, above all personal files, work folders and records from card files.
ANALYSIS OF FLUID-FLOW CHARACTERISTICS AND HEAT-TRANSFER PATTERNS AROUND A SQUARE BLUFF BODY
Authors: Etminan Amin , Harun Zambri
Published: June 2024

In this study, we investigate a numerical simulation of the flow and heat transfer characteristics around a single square cylinder subjected to incidence in a two-dimensional plane. The Reynolds and Prandtl numbers are set at Re = 100 and Pr = 0.71, respectively. The cylinder's surface is subjected to pressure and viscous forces due to the passing flow, with the magnitude of these forces influenced by the cross-sectional shape of the bluff body, the angle of attack, and flow velocity. The angle of orientation for the square cylinder varies from 0° to 45° in 5° increments. The study begins
with comprehensively examining the governing equations, simulation procedures, and grid generation, employing an
efficient and robust in-house finite volume code. Subsequently, we present and discuss the instantaneous streamlines, velocity components, vorticity, and isotherm patterns for different angles of attack. Additionally, global quantities such as viscous, pressure, total lift, drag coefficients, their root-mean-square, Strouhal, and Nusselt numbers are analyzed for various angles of attack. It is observed that the frequency of vortex shedding decreases with an increasing angle of attack. Furthermore, the values of global quantities and flow and temperature patterns remain relatively constant for angles of attack in the range of θ = 30°-45°. The numerical results show good agreement with experimental and numerical data in the existing literature.

Leaching of gold ore using creatine monohydrate
Authors: Ganji S.M.S. , Barani K.
Published: June 2024

Creatine was used as a lixiviant for gold dissolution from gold ore. The effects of creatine concentration, temperature, leach time, and pH were examined for their influence on extent of gold dissolution. The results show that at a temperature of 75°C and pH 11.5, gold dissolution increased from 51% to 88% on increasing creatine concentration from 25 to 50 g/t. Further increase in creatine concentration showed a negative effect on the gold dissolution. Gold dissolution increased from 47% to 87% by increasing the temperature from 25°C to 55°C, and from 61% to 89% by increasing pH from 10 to 11.5. Under the optimum conditions of solids' content of 30%, pH 11.5, creatine concentration of 100 g/t, temperature of 75°C, and hydrogen peroxide addition of 2%, about 90% of the gold could be dissolved from the ore after 24 h. A comparison between creatine and cyanide leaching showed that 90% gold dissolution was achieved at a cyanide concentration of 300 g/t, which is three times higher than the creatine concentration under optimal conditions.
Technology and growth in the South African mining industry: An assessment of critical success factors and challenges
Authors: Lumadi VW. , Nyasha S.
Published: June 2024

The mining industry has yet to fully accept and embrace the strategic role of technology and innovation in successful business planning and execution. In this study, we empirically determine the factors that influence acceptance of technology solutions in the mining industry in South Africa, assess critical success factors influencing adoption of advanced technology in the South African mining industry, and explore challenges faced by the mining industry in South Africa in adopting advanced technology in its operations. Thematic content analysis is employed in the data analysis. Results show that critical success factors to the adoption of mining technology include learning culture, knowledge sharing, high labour costs, and behaviour of other firms in the industry; commonly identified challenges include inadequate engagement with external stakeholders, uncertainties, the cyclical nature of the sector, and high risk related to the adoption of unproven technology and performance systems focused on volumetric production. The study encourages mining companies to implement usage of technology. This can be properly done through regular engagement with the Minerals Council South Africa.

ASSAf was acknowledged for bringing scholars and colleagues from learned societies together at this event and addressing current and controversial issues. Science can correct itself only through processes such as this.
Numerical Modelling Based Sensitivity Analysis of Stability of an Overburden Dump Slope
Authors: Gupta Gagan , Sharma Sanjay Kumar , Singh Gauri Shankar Prasad
Published: June 2024

Globally, design-based shortcomings caused many dump slope instability in the last two decades. Thus, the reliable design and a thorough understanding of the influencing parameters of an overburden dump structure is critical for its safe operation and maintenance. This paper reports a numerical modelling-based sensitivity analysis to develop an approach for designing an optimally safe dump structure in a limited space. The study was based on the large scale opencast workings of central India. The geometrical dimensions of dump structures were compiled from the major opencast workings, and geotechnical properties were based on the laboratory findings of geotechnical tests conducted on the dump material. The effect of total dump height, bench height, bench slope angle, bench width, cohesion and friction angle were evaluated considering a strong floor through the numerical simulation using FLAC 2D software. The friction angle possessed highest and total dump height had least influence on the dump slope structure. The FoS can be less than 1 even if a single bench fails instead of the entire dump structure. Hence, Displacement and shear strain parameters were incorporated in this study along with the safety factor to identify the instability prone zones. The statistical analysis was performed using SAS v7.15 software to determine the combined effect of considered stability governing parameters on the stability of dump structure by developing a mathematical model. The R-Square of the model was 0.988 with a standard error of 2.54%. The classification of output parameters is also done to deduce the state of stability.
Understanding Morphological Dynamics of the Mahanadi River Reach
Authors: Pradhan Biswajit , Anand Rakesh Kumar , Khatua Kishanjit Kumar
Published: June 2024

This work examines specific river morphometry parameters like bank erosion, active channel bank shift, and the sinuous behavior at identified stretches of the Mahanadi River. The specific stretches of the Mahanadi River from Baipur to Gopinathpur, Cuttack of around 270 km have been subdivided into five different reaches to simplify the study from a large scale to an average range. The Digital Shoreline Analysis System was used to investigate the river bank shifting and for the bank shifting prediction using Kalman Filter Model. The outcomes of the work show that, for the most part, the Mahanadi River is sinuous; however, at Kantilo, which is designated as reach four is meandering. In terms of Sinuosity, most reaches are unstable, whereas reaches 2 and 3 are stable. The flow area ratio to channel area has fallen by 25-30% due to the construction of barrages and dams in the upper portion of the Mahanadi River, affecting aquatic life, people and industries. At the same time, due to climate change, irregular rainfall causes floods in the lower reach of the river. The river flow erodes the bank along which it flows, even when the discharge is minimal. According to the bank shift analysis, the right bank is more unstable, ranging from 222 to -2900 m, while the left bank fluctuates from 996 to -1600 m. This study will help to understand the pattern of river bank shifting and change in the planform dynamics at the respective locations of the Mahanadi River.
Simulation of the Hydraulic Model HEC-RAS Coupled with GIS and Remote Sensing to Study the Effect of River Cross-section Width in Detecting Flood-prone Areas
Authors: Saini Dev Shree , Barik Dillip Kumar
Published: June 2024

Flooding is one of the extreme hydrological phenomena. It is a recurring natural disaster that causes loss of life and property in many parts of the world, particularly during the monsoon season. It is important to address such issues for local government and policymakers to manage the flood properly. One such flood management activity is to develop a flood-prone area that depicts the spatial and temporal extent of flood accurately. The integration of the Hydrologic Engineering Centre - River Analysis System (HEC-RAS) model and geospatial tools have emerged as a crucial approach for identifying and mapping flood-prone areas. The successful application of the HEC-RAS model generally depends on the topographical data, which represents the channel and floodplain geometry. In floodplain geometry, discrete cross-sections play a vital role to develop the floodplain map, particularly in the flat topographical region. To extract these data it needs a high-quality digital elevation model (DEM), such as light detection and ranging (LiDAR). However, due to a lack of high-resolution topographical data, flood hazard mapping in developing countries is rare. In common practice, the centerline of the river is considered the flow path for the channel. The orientation of the cross-sections is perpendicular to this line and extends to reach the limits of the floodplain. But, it is difficult to define the limits and it may depend on the magnitude of the flood. Hence, in this study, the HEC RAS model coupled with ArcGIS has been applied to the Ganga River, which traverses through the Bihar state of India to study the effect of cross-sectional width to define the floodplain. The Bihar state is facing substantial hardships from annual flooding events with approximately 16.5% of India’s flood-prone area. The extreme flood values for 5, 10, and 25 years of return period have been determined and the influence of the three different cross-sectional widths to mapping the floodplain has been investigated. This novel perspective adds dimension to the understanding of flood dynamics and its implications for flood risk assessment. In this analysis, it has been observed that, with an increase in the width of the cross-section, the floodplain area also getting increased. In this topographical region, keeping a fixed flow path will underestimate the flood-prone area. The width of the flow path depends on the topography of the region and the river flow. The outcomes of this analysis provide valuable insights into the flood-inundated areas for the specified return periods, enabling the identification and prioritization of flood-prone zones.
Petrology and Geochemistry of the Ultramafic Rocks of Yerrabali Schist Belt, Eastern Dharwar Craton, Telangana, India
Authors: Ramachandran G. , Das Sankha
Published: June 2024

The Yerrabali schist Belt (YSB) is a NW–SE trending 10 km long and 4 km wide belt located at the north eastern corner of Eastern Dharwar Craton (EDC) consisting of Banded Magnetite Quartzite (BMQ), ultramafic rocks, quartz–cordierite– gedrite ± garnet bearing schist, sillimanite–garnet–cordierite schist, metadolomite, amphibolite, ferruginous quartzite, tremolite schist and dolerite dyke. The ultramafic rocks consist of olivine, orthopyroxene, clinopyroxene and spinel. The Fe content of olivine varies from 88-91 and consists of high amount of NiO (0.3-0.511%). Orthopyroxone are enstatitic and clinopyroxene are Mg-augite in nature. The spinel grains are rich in Al2O3 (48.32-59.09%) and show very low Cr# values (0.08-0.29). Thermo-barometric analyses show equilibrium condition of 700°-1100°C temperature and 19-21 kb pressure. Oxygen fugacity of the ultramafic rocks range from -0.035 to -1.356 log units below FMQ buffer. Low Cr# values of spinel along with low oxygen fugacity suggest their formation by low degrees of partial melting from a less refractory Mid Oceanic Ridge (MOR) type mantle.
Ground Prediction by Markov-ANN Hybrid Analytics Using Baseline Geotechnical Data and Observed Field Data
Authors: Sharma Aman , Maji V.B.
Published: June 2024

Geology along the tunnel length usually differs from the anticipated data as per Geotechnical Baseline Report (GBR), sometimes quite significantly. This has always led to the disruption of the planning, resource mobilisation, cost and duration of the project. One way to minimise this uncertainty is by exhaustive investigation like probe holes and geophysical prospecting. Forecasting or prediction of Geology can also be done by soft computing and analytical methods. Using the analytical tool of the Markov Model and the learning powers of Artificial Neural Networks (ANN) has been attempted in this study. The idea is to build a hybrid model that would combine both capabilities and do a probabilistic prediction of the ground condition ahead of the tunnel face in real time to better suit the site, accommodate complexities and can capture the associated uncertainties. The Geotechnical Baseline Report (GBR) having the initial survey details of the tunnel geology is used to build the Markov Model while the deterministic borehole data in the GBR is used to build the ANN model. Bayesian joint probability theorem is used to update the model with the face observed geological parameters. This hybrid model demonstrated to be a good complement to the physical forecasting methods and the geological uncertainty of a complex and challenging Himalayan region was well captured by the present approach. The window of the prediction was for a region of approximately 250m where it showed a very good prediction of ground class. The model can help in systematic planning and resource mobilisation in a better way and subsequent key decisions for the upcoming excavation method and corresponding support measures.
SMRT-Tag -Direct transposition of native DNA for sensitive multimodal single-molecule sequencing v2
Authors: Nanda Scott , Wu Ke , Irkliyenko Iryna , Kasinathan Siva , not provided vijay.ramani
Published: June 2024

Here we describe a protocol for SMRT-Tag: Single-Molecule Real-Time sequencing by Tagmentation - a transposase-mediatedstrategy for producing low-input, multiplexable, PCR-free PacBio sequencing libraries. SMRT-Tag requires only 1-10% as much input material as existing PacBio protocols (typically at least 1–5µg, or 150,000–750,000 human cells) and enables highly-sensitive and simultaneous detection of sequence variation and CpG methylation comparable to the current state-of-the-art. In brief, high-quality genomic DNA is tagmented using Tn5 transposase loaded with custom hairpin adaptors, gap-repaired to generate closed and circular templates, exo-digested to remove unrepaired molecules, and then sequenced on the PacBio Sequel II platform. All steps from purified gDNA to sequencing-ready libraries can be performed in one day. We have demonstrated the utility of SMRT-Tag on input as low as 40ng gDNA (~ 7000 cell equivalents) sequenced monoplex.

Auf dem Weg in eine klimaneutrale Produktion wird dem Product Carbon Footprint (PCF) bei der Produktion von Automatisierungskomponenten und deren Energieverbrauch über den Lebenszyklus zukünftig eine stärkere Bedeutung zukommen. Unternehmen priorisieren derzeit die Optimierung des eigenen Anteils am PCF inkl. fremdbezogener Energien. Der Anteil des PCF durch Investitionsgüter ist schwieriger zu erfassen, ist aber dominant bei Anlagen der Prozessindustrien. Der Beitrag diskutiert Anteile des PCF über den kompletten Lebenszyklus pneumatischer Antriebe und weiterhin erste Ansätze, den PCF für Alternativtechnologien zu bewerten.
A Seismic Nodal Deployment to Understand Magmatic Structure in the Vicinity of the Pāhala Earthquake Swarm
Authors: Janiszewski Helen , Bennington Ninfa , Wight Jade
Published: June 2024

In Summer–Fall 2022, 80 three-component SmartSolo IGU-BD3C-5 nodal seismometers were deployed surrounding the Pāhala seismic swarm on the Island of Hawai‘i, with the goal of improving seismicity catalogs and seismic velocity images of the crust and upper mantle in this region. The Pāhala swarm, located south of Mauna Loa and Kīlauea, has been the site of a multiyear sustained swarm of seismicity at the depths of ∼25–40 km, with order of magnitude increases in rate in 2015, and then again in 2019. This seismicity is possibly related to the input of magma from the mantle plume below, which may then be subsequently transported to volcanic edifices. However, these processes remain enigmatic, in part due to a lack of precise earthquake locations and seismic velocity models in this region. Here, we provide an overview of the deployment, an assessment of the quality of the collected data, and discuss the viability of the data set for local earthquake relocation, tomography, and teleseismic receiver functions. Through comparisons with proximal permanent broadband and short-period instruments, we find that the nodes produce high-quality data, particularly at periods shorter than 5 s, although we find, document, and correct discrepancies with the gain and polarities of the instruments. We successfully record signals from teleseismic earthquakes, even at periods longer than 5 s (the corner of the flat response of the nodes). We also record local earthquakes, including details related to source characteristics. This indicates that the data are likely to prove useful for investigations using both local and teleseismic earthquake signals to better understand the connections between the deep and shallow magmatic systems of Hawai‘i. Although this deployment provides a snapshot in time, its success may provide a useful benchmark for future studies as the volcanic systems of Hawai‘i continue to evolve in the future.
Untangling the Tangle of Revenge Porn in the United States: A Comparative Study
Authors: Fernando Zico Junius , Pase Ana Tasia
Published: June 2024

This research examines the phenomenon of revenge porn in the legal context of the United States and identifies important lessons for Indonesia. Using a multifaceted approach, this research explores legal definitions, sentencing, and protections for victims in various US states, as well as exploring the psychosocial impact of revenge porn on victims. This research utilizes normative legal methods by adopting statutory, conceptual, comparative, and futuristic approaches. The nature of this research is descriptive-prescriptive. The data that has been collected is analyzed using the content analysis method. The study found that there is significant variation in laws and approaches to handling revenge porn among states, reflecting differences in social values and legal priorities. For example, states such as California, New York, and Texas feature different definitions and penalties, as well as varying levels of protection for victims. Indonesia can draw valuable lessons from formulating its own legal strategy for this phenomenon. This research suggests the importance of specific legislation that clearly defines revenge porn, a flexible sentencing system that considers the context of individual cases, and strong psychosocial support for victims
