Published: January 2024

Identifying Customer Induced Damage (CID) is a key part in warranty programs of electronics manufacturers. CID is defined as any damage in the unit performed by an unauthorized person including the customer in a Printed Circuit Board (PCB). In such cases, damaged units are not covered by warranty. The inspection of CIDs is usually performed by humans which may be costly and error prone. Modern computer vision techniques for object detection using deep neural networks can automatically and accurately detect CIDs on PCBs. The training of such networks requires a large labeled dataset of image examples of CIDs. Daily, hardware factories and repair centers generate hundreds of unlabeled images. Labeling them manually is laborious and time-consuming. Therefore, it is crucial to label the minimum amount of images such that the trained neural network can achieve comparable accuracy as if it were trained with the whole dataset. To this end, we propose an active learning approach that selects the most informative images for the object detector. For that, our approach is based on the uncertainty of the object detector, i.e., it selects new images based on class probability distribution given by the object detector. Also, we tackle some challenges that are intrinsic to this problem: i) it is a multiclass object detection problem since there are many types of defects; ii) there is a class accuracy imbalance; iii) there is a focus on recall, e.g. false positives are less harmful than false negatives, and iv) there are many images with no object which should not be selected for labeling. We evaluate this approach by using it to iteratively sample data, train and evaluate a model, and compare it with randomly sampled data. The results show that our method consistently outperforms random sampling by an average margin of 21.6%, proving to be a viable alternative for reducing the labeling cost and increasing detection accuracy in this domain.

MULTIVARIATE ASSESSMENT OF SURFACE WATER QUALITY AND FINAL PUBLIC WATER SUPPLY IN BELÉM, PARÁ, BRAZIL. The present study investigated the sources of variability in the water quality of surface springs that supply the Metropolitan Region of Belém (Pará, Brazil), as well as the treated water produced by the main water treatment station in the region. Data provided by Companhia de Saneamento do Pará were used, referring to physical-chemical and bacteriological analyzes carried out in the period from 2010 to 2020. In addition, precipitation data were considered in this study, in units of mm of rain, obtained by consulting the database of the National Institute of Meteorology. The application of principal component analysis, as an exploratory data analysis tool, allowed the grouping of the most relevant parameters of the results and proved to be efficient in reducing the data set, explaining more than 65% of the total variance, in all objects of study. Thus, it was possible to observe a general profile of the quality of surface water investigated, and, in this way, demonstrate the impact of urban pressure on the environment, as well as the need for maintenance and conservation of surface water resources.
A comparative analysis of text worlds’ elements in the literary tale “Cinderella” by Charles Perrault (translated into Russian) and its screenplay by Yevgeny Schwartz
Authors: Evseev Oleg V. , Koh Aleksandra N. , Mikhalkova Elena V.
Published: January 2024

Formal comparison of literary texts often seems difficult due to hidden meanings, allegories, and the authorial style. As a solution to this problem, linguists propose the Text World Theory (TWT), according to which each text consists of text-world elements (characters, time, and place of action) and changes within them that cause switching from one text world (TW) to another. TWT is well suited for studying versions of a single plot, as it formalizes the narrative structure of the text. This study presents a comparative analysis of the elements of text worlds in Charles Perrault’s fairy tale “Cinderella, or the Glass Slipper”, translated into Russian by Tamara Gabbe, and the film script Cinderella by Yevgeny Schwartz, based on Perrault’s fairy tale. To better understand differences in the elements of TWs in a literary tale and its screen adaptation, the two texts were annotated using an XML markup. For analysis, such elements of text worlds as characters and markers of place were automatically extracted. Intermediate results show that, although the elements of the text worlds in both texts are largely similar, there are marked differences in the ranged frequency of their occurrence and elements that surround them. The differences are explained by the fact that Perrault’s literary fairy tale belongs to the epic genre, and Schwartz’s film script — to the drama, as well as the artistic style and individual perception of the story by the two authors. The genre features require Schwartz to provide more detail on characters and locations. The analysis shows that he seeks to preserve and even expand the romantic presentation of Perrault’s plot, even taking certain risks (e. g., calling the fairy with a religious, Christian naming: “godmother”). At the same time, the shift in focus from the prince to the king father in the script indicates a deeper psychologism. It is planned to expand the research by adding new literary works to the corpus. This article was presented as a paper at the 8th Research Conference "Conference on Text Interpretation: Data Analysis in the Social Sciences and Humanities" (17 July 2022, Institute of Social Sciences and Humanities, University of Tyumen).
Aramaic targums and daily religious life
Authors: Sidorenko Natalia V.
Published: January 2024

The connection between the written Targums, which are translations of Sacred Scripture into Aramaic, and the oral Targums used in synagogues is not well understood. Rabbinical tradition suggests that the Targums were written to make Scripture understandable to ordinary people during synagogue readings. However, the article argues that the Targums were also associated with various aspects of daily religious life, reflecting the ideas and realities of the 4th–5th c. CE when they were created. We discuss discrepancies between written rules and real-life practices, individual and communal study of Targums, their place in translation and commentary traditions, and traces of oral speech in their language. We also explore their use in protective spells inscribed on “magic cups.” Finally, we draw typological parallels between Targumic texts and Church Slavonic liturgical language in the early 20th c., both designed to preserve sacred languages in worship.
Paul Cuffe: navigator, businessman, abolitionist
Authors: Shumakov Andrey A.
Published: January 2024

This article is the first in Russian historiography to provide a detailed biography of the legendary African American abolitionist and entrepreneur, Paul Cuffe. He is often referred to as the pioneer of the “Back-to-Africa” movement and a founder of the black nationalism ideological and political trend. Cuffe’s success story and public activism have inspired generations of fighters for black rights in the United States, making him one of the most revered figures in African American history. Two centuries after his untimely death, interest in Cuffe continues to grow, as evidenced by the increasing number of publications on this subject. The purpose of this work is to review Paul Cuffe’s biography using reports, letters, works, and materials from periodicals, as well as research materials from leading Western experts. The study aims to consider the early period of Cuffe’s life and his entrepreneurial and social activities. Historical-descriptive and comparative-historical methods are used to draw parallels with similar historical figures like Prince Hall. The author concludes that Cuffe’s entrepreneurial activity was closely linked to his social work. He saw the repatriation project as a promising economic venture, as evidenced by his long and systematic fundraising efforts. Cuffe’s views were influenced by the development of free trade in the late 18th and early 19th c. Regarding Cuffe’s representation as a founder of black nationalism and Pan-Africanism, the author does not find direct confirmation of this point of view during their research.
Mythopoetics of V. Y. Zazubrin’s novel “Mountains”: Eros and Thanatos
Authors: Bogumil Tatiana A.
Published: January 2024

This article examines the erotic and thanatic imagery and motifs in V. Ya. Zazubrin’s novel “Mountains” within the context of the Yermak’s plot, which revolves around the universal theme of conquering the land-woman. The Yermak’s plot, foundational to Siberian Russian cultural texts, is associated with the traditional motif of “capture of a city = enthronement = wedding / violence / fornication”, along with the motif of “death of a man by a woman / water”. Through a mythopoetic analysis of selected works about Siberia, it becomes evident that the analogy of woman-country is further clarified by the analogy of woman-earth/water. In V. Ya. Zazubrin’s novel, which explores the civil war and collectivization in Altai, the metaphorization of gender poetics is observed through aquatic, animal, and plant semantic codes. The novel embeds the “gender issue” within the main plot, determining not only the individual fate of a “private” man, but also the specifics of national history. This study sheds light on how river imagery in Siberia, such as the Ob and Biya rivers, is depicted using obscene language, which can be interpreted as a relic of symbolic copulation with Mother Earth. Keywords: geopoetics, Siberian text, image of Altai, Yermak’s plot, F. M. Dostoevsky, V. Ya. Zazubrin
Semiotics of color in S. N. Durylin’s prose in light of E. Troubetzkoy’s and P. Florensky’s ideas
Authors: Nepomnyaschikh Natalia A.
Published: January 2024

S. N. Durylin’s writing is filled with a wide range of vibrant colors: the text is abundant in colorful descriptions, metaphors, and unique words coined by the author to represent different shades and hues. These color references are consistently used and often serve as symbols for the ethereal and true essence of the world. The use of color symbolism is essential in portraying Holy Rus’, specifically the Russia before the revolution. S. N. Durylin’s ideas on the semiotics of color might have been influenced by the thoughts on color in Russian iconography shared by P. Florensky and E. Troubetzkoy, both of whom he had regular contact with. Durylin not only drew inspiration from his friendship with Troubetzkoy, but also from his own fascination with icons. In his prose, Durylin effectively incorporates the concepts of color put forth by E. Troubetzkoy and P. Florensky in their interpretation of Russian iconography.
Differential-difference systems in the analysis of weak solvability of initial-boundary value problems with a spatial variable in a network-like domain
Authors: Hoang Van Nguyen , Provotorov Vyacheslav V.
Published: January 2024

In the work, the approach and the corresponding methods, which make it possible to construct a priori estimates of weak solutions of a differential-difference system with a spatial variable varying in a multidimensional network-like domain are indicated. Such estimates in spaces of summable functions are used to find solvability conditions for boundary value problems of various types for differential-difference systems. In addition, a priori estimates are used to justify the application of the method of discretization with respect to the time variable (semi-discretization) to the analysis of the weak solvability of initial-boundary value problems and the subsequent construction of approximations of weak solutions. The rationale for the approach used is the fact that in a fairly wide class applied analysis of the problems of transporting continuous media networks-like carriers, the representation of mathematical models of the process using the formalisms of differential-difference systems is the only tool for effectively solving these problems. For example, the reduction of a differential system (initial-boundary value problem) to the corresponding differential-difference system makes it possible not only to significantly simplify the analysis of problems of optimal control of a differential system (since this analysis reduces to studying the problem of optimal control of a system of elliptic equations), but also, using classical methods of control theory for elliptic systems, algorithmize the original problem. The reduction used often facilitates establishing the conditions for the existence and uniqueness of optimal control of a differential system. These problems also include a fairly large range of studies of non-stationary network-like hydrodynamic processes and flow phenomena. As an illustration of the approach used and the results obtained, the analysis of the solvability of the linearized Navier–Stokes system is given and the ways of studying the nonlinear Navier–Stokes system are indicated.
Numerical simulation of the water-ice phase transition in highly permeable water-saturated porous media
Authors: Simonov Oleg A. , Filimonova Lyudmila N.
Published: January 2024

Modeling a phase transition in porous media is a complex mathematical problem that is often encountered in practice. For its successful solution, it is necessary to take into account many parameters, in particular, the convective movement of unfrozen water. Free convective currents in a porous medium, of course, affect the process of phase transition during its freezing, but it is obvious that in some cases the influence of this phenomenon can be neglected. The purpose of this work is to study the mechanisms and degree of influence of free convection on the freezing of a water-saturated porous medium. The phase transition in a porous medium was simulated numerically, taking into account the inversion of the water density. The role of the convective flow on the crystallization of water in a porous medium was studied, as well as the influence of the selected water model on convective flows in order to obtain criteria that determine the need to take into account these physical phenomena and properties in solving thermophysical problems with a phase transition in porous media, which can significantly simplify the modeled system. An axisymmetric model problem with a vertical cooling element immersed in a water-saturated porous medium is solved. The temperature of the cooling element changed slowly, and the temperature at the outer boundary of the porous medium was maintained constant.
The influence of convective heat transfer on the process of phase transition in a porous medium is estimated taking into account the phenomenon of water density inversion. It is shown that the presence of a water density maximum significantly determines the process of phase transition in porous media. In comparison with numerical models that do not take into account the phenomenon of density inversion, when using the real water model, the flow is restructured, the intensity of the convective flow decreases, and the volume of ice formed increases. The influence of the permeability of a porous medium on the structure of the resulting convective flow has been studied; with a decrease in permeability, the presence of a density maximum leads to a decrease in the role of convective heat transfer, which in most cases makes it possible to ignore it in problems with an ice-water phase transition in porous media.
Investigation of the temperature distribution in a heterogeneous reservoir during fluid filtration, taking into account thermodynamic effects
Authors: Suleimanova Malika D. , Sharafutdinov Ramil F. , Kanafin Ildar V.
Published: January 2024

Based on the modeling of non-isothermal fluid filtration, taking into account the Joule–Thomson effect and the adiabatic effect, the formation of temperature in a porous medium with radial-angular permeability heterogeneity is studied.
It is shown that the presence of heterogeneity in the near-wellbore formation zone leads to different rates of temperature establishment in the angular distribution after the well is put into operation. Depending on the ratio of the permeability of the formation and the area of heterogeneity during fluid filtration in the angular distribution of temperature in the well, either a slow rate of temperature establishment in the region of heterogeneity is observed. The area of heterogeneity is colder than the rest of the area, or vice versa, the area of heterogeneity has an increased temperature.
The results obtained complement the known data on the formation of temperature fields in reservoir conditions with non-isothermal fluid filtration, taking into account thermodynamic effects, and can be used to interpret the results of multi-sensor temperature studies in wells with formations that are heterogeneous in permeability.

Published: January 2024

The paper presents a new method of seismic exploration, which includes two receivers of acoustic signals, deepened into the rock one under the other at some distance. These receivers record seismograms which are the acoustic signals, the source of which can be the natural seismic activity of the Earth’s crust or targeted sources of acoustic signals, such as an explosion. Simulation of the direct problem of seismic exploration was performed using the COMSOL Multiphysics and MatLab software packages. The seismograms obtained during the simulation are combined and added with each other with the on the delay time shift of the input seismic pulse between the receivers. In this case, the signals that came along the vertical, “amplify” each other on the total seismogram, and non-vertical signals are damped. The correlation function of seismograms was obtained for mathematical simulation. The results of modeling the propagation of an acoustic wave in rocks and an example of processing seismograms according to the proposed algorithm are given. The presented results show that the new method of receiver location and the method of processing seismograms make it possible to obtain a cleared seismogram that can be used to solve the inverse problem of determining the parameters of the geological environment.
Mathematical model of killing an oil horizontal well
Authors: Korotchenko Andrey N. , Kislitsin Anatoliy A.
Published: January 2024

The physical picture of the killing fluid and the formation fluid movement in the process of killing a horizontal oil well has been described, a physical and mathematical model of the process has been developed and the limits of the model applicability have been indicated. It is recommended to conduct the killing process in two stages, separated by a technological break. During the first stage, the injected killing fluid fills the tubing, the annulus and the part of the horizontal wellbore. For the duration of the technological break, the denser tubing slowly displaces the formation fluid from the horizontal wellbore into the annulus where the formation fluid floats to the surface in the form of droplets. For the period of the second stage, the remaining amount of tubing is pumped into the well. The model is based on the well-known hydraulic equations for laminar flow of liquids, the solution of the flooded jet problem, as well as the model of one-dimensional vertical inertialess flow of a two-phase medium with incompressible phases. A closed system of equations has been formed taking into account the viscous friction losses on the walls of the horizontal pipe and at the interface between the formation fluid and the killing fluid flows. The solution of this system has been obtained and the values of the main process parameters have been found: velocities and flows of liquid gas and liquid coolant and time of complete replacement of liquid coolant by the killing fluid depending on the inclination angle of the horizontal pipe. It is shown that the character of the movement of the formation fluid drops in the pipe space depends on their volume fraction φ in the mixture with the killing fluid. With the value φ < 1/3 the jelly drops float up with a constant speed, while the jelly droplet radius and the speed of their floating up are unambiguously determined by the jelly stream size, density and viscosity of jelly and liquid hydrocarbon. The graphs of dependence of these parameters on the value of the formation fluid flow have been presented. On the basis of the research the recommendations for the process of killing horizontal oil wells have been formulated.
The simulation of non-stationary gas pressure in a pipeline with pumping and injection
Authors: Chuprov Ilya F. , Lyutoev Alexander A. , Parmuzina Maria S.
Published: January 2024

In this work, based on the fundamental research of I. A. Charny on the unsteady movement of a real fluid in pipes, an equation that describes the pressure dynamics in a complex section of a gas pipeline was compiled. The use of the Dirac impulse function made it possible to describe the dynamics of unsteady pressure in a single equation in the case of point pumping and injection at given points. Linearization of the model by averaging the velocity of the gas made it possible to bring the equation to a hyperbolic form. If we neglect the forces of inertia compared to the forces of resistance, then the mathematical model will represent a partial differential equation of the second order parabolic type. The dynamics of pressure at specific points of pumping and injection under boundary conditions of the second kind (rates are given) was obtained using the finite cosine Fourier transform.
The working formula that allows you to determine the pressure at any point at a given point in time is a trigonometric series. The series are rapidly convergent, so there is no difficulty in working with them. Particular cases are considered (without pumping and injection). The fulfillment of the boundary conditions is checked. It is easy to rebuild the working formula for pumping and / or injection at several points in a given area.
Calculations of the mass flow and average velocity are made. In practice, the pressure is usually set at the start and end points of the area under study. In this case, it becomes possible to go to the costs (to derivatives) at the ends of the section under consideration.
New approaches to simplification of integrated asset models
Authors: Padin Egor A. , Yushkov Anton Yu.
Published: January 2024

The current trend in modeling of the development of oil and gas fields is the transition from models of individual elements of the production system to complex integrated asset models (IAM) of hydrocarbon production fields. The use of such models is especially relevant for the correct forecasting and management of hydrocarbon production in gas, gas condensate and oil and gas condensate fields, where the parameters of facility infrastructure determine the dynamics of production no less than wells and productive reservoirs.
The complexity of integrated asset models is associated with the labor-intensive of its creation and the high requirements for computational and time resources required to create and maintain models.
This article proposes approaches to increase the efficiency of calculations of integrated asset models while maintaining the quality of forecasting, which helps to increase the value of modeling and the degree of details of development of project solutions. A study of four integrated asset models configurations was carried out. Firstly, the operating features of a detailed integrated asset model are presented, and then methods for simplifying both the reservoir model and the gathering system model are described. For each model, key characteristics are given, as well as calculation algorithms.
Through the example of a gas field, a numerical experiment was performed using all the considered configurations; a comparison of the main technological parameters of development was carried out, which showed similar results for all configurations.
Based on the study, a conclusion was made about the possibility of using such simplified integrated asset models to perform operational, including multivariate calculations in addition to detailed integrated asset models.
Grande demais para falhar a Geração Millennial nas margens

Published: January 2024

n Too Big to Fail: Millennials on the Margins, the authors return to the question of how skills are distributed across the millennial population, focusing on the size and demographic characteristics of U.S. millennials with low literacy and numeracy skills, and the resulting impact on social and economic outcomes. They do this in part by examining the issue of “disconnected youth”, a term typically applied to those ages 16-24 who are not employed or engaged in formal education or training. Since the Great Recession of 2008, researchers have become increasingly concerned with these disconnected youth who, according to some estimates, represent approximately 6 million young adults in the United States. The focus of this research has been on their educational attainment and labor market participation. While helpful, this approach is limited in two ways. First, it focuses on only our youngest adults at a time when the transition to adulthood is more prolonged. Second, it is based on the premise that employment and/or more education are assured catalysts for entry into the middle class and improving life outcomes. The authors question whether this assumption is appropriate to current circumstances; they suggest that looking at young adults only in terms of ties to the labor market or formal education may underestimate the scope of the challenges that we face and may skew our understanding of the policies needed to alter our course.
Accessibility risk management in Brazilian museums
Authors: Stiegert Isabela , Froner Yacy-Ara
Published: January 2024

Museums and cultural spaces must be democratically accessible throughout society, including people with disabilities and reduced mobility, who represent a large part of the world's population. In Brazil, accessibility in museums is still moving at a slower pace compared to the world, which occurs for several reasons, among them, the constant and growing cut of resources for investment in culture in the country. The Brazilian Institute of Museums (IBRAM) developed a risk management program in museums that was launched in 2013, and updated in 2021, which still does not address accessibility within risk management and fails to direct greater care to this public in risk management, which interferes with the safety of these people and the safety of museum spaces.
Heritage Science Networks and public policies: the importance of protocols, standards, and normative tools, and the Brazilian Institute of Museums guidelines regarding collections risk management
Authors: Froner Yacy-Ara
Published: January 2024

In recent years, countless collections have been destroyed by acts of vandalism, war crimes, negligence, and accidents. Their loss can be seen from the perspective of the potential loss of their studies, but above all by understanding their impact in relation to the emptying of the voices of native communities, destruction of the memory of religious, racial, political, cultural, and territorial properties of certain groups or societies, and the disappearance of production systems, both in relation to everyday and symbolic objects. In Brazil, the impact of fires on public museums amplifies these issues. In 2020, the Federal Government sanctioned the Resolution No. 2, providing for the technical and administrative procedures for the preparation, implementation, and evaluation of risk management plans for museums, within the scope of units managed by the Brazilian Institute of Museums - Ibram. This contribution intends to discuss the conceptual and technical issues regarding risk and conservation assessment, as well as the guidelines on the protection of collections in museums and connect it with the demands generated by the Ibram´s instructions. It is part of the research “Protocols for the sustainable management of collections in museums: technicalscientific skills for the definition of standards, recommendations, and public safeguard policies” financed by the National Agency of Research (CNPq)

Published: January 2024

Bencana kekeringan merupakan fenomena alam yang harus diwasdapai agar suatu daerah tidak mengalami dampak negatif secara ekstrem. Kabupaten Blitar merupakan salah satu kabupaten di Provinsi Jawa Timur yang rawan terjadi bencana kekeringan. DAS Lekso adalah salah satu wilayah Kabupaten Blitar yang rentan terhadap kekeringan. Maka dari itu, diperlukan analisis kekeringan untuk mengetahui kondisi tingkatan kekeringan yang terjadi di DAS Lekso. Studi ini menggunakan metode Rainfall Anomally Index (RAI) untuk menghitung indeks kekeringan. Diperlukan data tambahan agar dapat mengoptimalkan hasil analisis kekeringan dikarenakan stasiun hujan yang terdapat di DAS Lekso tidak tersebar secara merata. Oleh karena itu, studi ini memanfaatkan data satelit CHIRPS untuk perhitungan data stasiun hujan rencana. Lokasi titik stasiun hujan rencana tersebut ditentukan berdasarkan jaring-jaring metode kagan roda. Hasil perhitungan indeks kekeringan RAI selama 20 tahun pengamatan menunjukkan bahwa pada DAS Lekso terjadi 7 tahun kekeringan terparah yaitu pada tahun 2002-2003, 2006, 2014-2015, dan 2018-2019. Berdasarkan pola tren kekeringan, diperkirakan bahwa kekeringan di DAS Lekso terjadi setiap 2 hingga 7 tahun. Sehingga berdasarkan penelitian, data satelit efektif digunakan sebagai data tambahan untuk mengoptimalkan analisis kekeringan.

Beyond Neoliberal Presentism: An Eco-Temporality for the Anthropocene
Authors: Volpi Alessandro , Cera Agostino
Published: January 2024

Abstract: In this paper, we examine the relationship between neoliberal presentist temporality and the climate-environmental crisis, arguing for the necessity of envisioning a new “eco-temporality”. The deconstruction of the modern concept of progress in postmodern thought and postcolonial studies is considered, making a case for the undesirability of its complete abandonment – since a progressive temporality retains a role in enabling political change and long-term vision. To capture the connection between politics and temporality we develop the concept of “political temporality”, which we define as the schema of interaction between the social representation of time and what is perceived as politically feasible in each community at a given time. Furthermore, we analyse the most prominent features of neoliberal temporality (structural presentism, the public/private distinction, individual subjects, and philosophy of history), sketching an account of how each of them impacts ecological and climate politics. Finally, to envision a new, Anthropocene-friendly “regime of historicity”, we lay down two basic conditions that an “eco-temporality” should satisfy. In the last two sections, we sketch a new (multi)temporal model that is meant to be apt for the Anthropocene, drawing on Ernst Bloch’s concepts of “multiversum” and “contemporaneity of non-contemporaneous elements” (Bloch, 1970, 1991).

Authors: Aziz Kardo Othman , Abdulrahman Teimoor Ramyar , Ahmed Tofiq Tofiq , Salih Abdulla Dilman
Published: January 2024

In natural language processing, morphological generation refers to the creation of the appropriate inflected forms of words based on a predetermined set of morphological rules. However, it might be difficult to generate morphology in languages with intricate morphological systems, like the Kurdish Sorani dialect. The concatenative morphology-based unique technique to morphological generation in Kurdish Sorani is proposed in this research. The suggested strategy tries to get over the drawbacks of current approaches and enhance the precision and effectiveness of morphological generation in Kurdish Sorani. The suggested technique generates all conceivable subjective and objective pronouns in both positive and negative forms, together with the various verb tenses for Kurdish morphology. The study presents a detailed examination of Kurdish Sorani’s morphology and points out the difficulties in coming up with the right verbforms. The authors suggest a concatenative morphology-based morphological generating system that comprises of a morphological analyzer and a morphological generator.
Grasshopper (Oxya chinensis) Gut Bacteria and their Cellulolytic Activity
Authors: Munir Erman , Sitinjak Irma Vanessa , Nasution Ahmad Faisal
Published: January 2024

Lignocellulose is a core component of plant biomass and the most abundant carbohydrate polymer in nature. It is cheap and renewable and has several potential applications; however, it remains underutilized because of its recalcitrance to degradation. Cellulolytic microbes have been found in the gut of herbivorous insects, such as grasshoppers. This study aimed to isolate lignocellulolytic bacteria from the gut of grasshoppers (Oxya chinensis) and determine their diversity and potential biomass-degrading activity. A total of 27 culturable isolates were obtained from the grasshopper foregut, midgut, and hindgut. The bacteria hydrolyzed cellulose and lignin, as indicated by a cellulolytic index of 0.12–1.23 and ligninolytic index of 0.1–1.47. Five potential cellulolytic bacterial isolates were selected. Based on 16S rRNA sequencing, the isolates were identified as Bacillus wiedmannii (foregut), Bacillus marcorestinctum, Bacillus halotolerans (midgut), Paenibacillus zanthoxyli, and Bacillus hominis (hindgut). The highest specific cellulolytic activity (0.0068 U/mg) was detected in B. wiedmannii (OCF2), which could be exploited as a potential source of cellulases.

Structural Analysis of Self-Balancing Robot
Authors: Sayyad Dr. M. M.
Published: January 2024

Abstract: A two-wheeled self-balancing robot is a classic example of inverted pendulum model. Exploring the realm of inverted pendulum systems, the two-wheeled self-balancing robot stands as a quintessential example, showcasing its inherent natural instability. In contemporary times, this system has emerged as a focal point of research, drawing attention for its extensive potential applications, ranging from Segway vehicles to enhanced wheelchairs and more efficient robotic designs. Within the scope of this project, a deliberate effort has been undertaken to confront and mitigate the inherent instability of the two-wheeled self-balancing robot through the implementation of a PID control system. This paper aims to carry out static structural analysis on the robot carrying maximum weight and subjected to road conditions. The robot model used in analysis is designed in SolidWorks and includes primary assembly. Analysis was performed in the Static Structural Suite of ANSYS Workbench.
Who do we Pay for Music: Artists or DSP\'s?
Authors: Gupta Eesha
Published: January 2024

Abstract: The involvement of digital service providers (DSPs) or platforms, such as Spotify, Apple Music, and Tidal, that deliver streamed music, has significantly transformed the functioning of copyright management organizations (CMOs) and the compensation structure for songwriters and recording artists. The concept of platform economics has originated from the economic analysis of two-sided and multi-sided markets, providing fresh insights into business practices in the digital realm. This concept is now being applied specifically to the domain of music streaming services.

Penelitian dilaksanakan selama 3 bulan di Laboratorium Ilmu Nutrtisi Ternak Perah Departemen Ilmu Nutrisi dan Teknologi Pakan Fakultas Peternakan IPB. Penelitian menggunakan Rancangan Acak Kelompok (RAK) dengan 5 perlakuan dan 4 kelompok. Materi yang digunakan adalah ransum yang terdiri dari hijauan dan konsentrat dengan perbandingan 60% + 40%. Hijauan terdiri dari rumput lapangan (70%) dan pod kakao (Theobroma cacao) fermentasi (30%). Konsentrat terdiri dari kapur/dolomit, garam, tepung ampas tahu dan dedak padi halus. Perlakuan yang diujikan adalah A= ransum tanpa suplementasi (sebagai kontrol), B= suplementasi mineral (S 0,11%, P 0,08%, dan Zn 20 ppm), C= B + 0,4% S. cereviceae, D= B + 1% tepung indigofera E= suplementasi mineral (S 0,11%, P 0,08% dan Zn 20 ppm) + probiotik (0,4% S. cereviceae) + by-pass protein (1% tepung Indigofera sp). Parameter yang diamati adalah populasi bakteri total dan bakteri selulolitik rumen. Hasil penelitian menunjukkan bahwa perlakuan berpengaruh sangat nyata (P<0,01) terhadap populasi bakteri total dan bakteri selulolitik rumen. Populasi bakteri total dan bakteri selulolitik rumen yang dihasilkan berkisar 5,75-8,65 dan 4,80-8,60 (log cfu/ml). Populasi bakteri total dan bakteri selulolitik rumen tertinggi terdapat pada perlakuan E, yaitu suplementasi mineral dengan probiotik dan by-pass protein. Dari hasil penelitian dapat disimpulkan bahwa pemanfaatan pod kakao fermentasi dengan suplementasi mineral, probiotik dan by-pass protein dapat meningkatkan populasi bakteri total dan bakteri selulolitik rumen secara In-vitro. Kesimpulan dalam penelitian ini adalah pemanfaatan pod kakao fermentasi dengan suplementasi mineral phosfor (P), sulfur (S), dan Zn), by-pass protein dan proboiotik mampu meningkatkan populasi bakteri total dan bakteri selulolitik rumen secara In-vitro

The nickel ore export ban policy has drawn pros and cons in various circles. This study aims to analyze the impact of the nickel ore export ban on other sectors of the economy and the interrelationship between one sector and another. This study uses secondary data in the form of Indonesia's Input Output Table Total Transactions at Basic Prices in 2016 derived from BPS publications and data on the number of Ferro-nickel exports in 2020 derived from UNData publications, which are then analyzed using the input-output method and presented using descriptive quantitative analysis. Based on the research results, electricity and gas procurement are the economic sectors with the most significant backward linkage. In contrast, the manufacturing sector achieves the most significant forward linkage value. In addition, the electricity and gas procurement sector also has the most significant output multiplier value, followed by the construction and manufacturing sectors. The increase in Ferro-Nickel exports due to the nickel ore export ban has considerably impacted the economy regarding both domestic and import output, especially in the manufacturing industry sector. Thus, nickel ore processing activities depend on capital goods and other imported raw materials. The study's implication shows that the export of Ferro-Nickel as part of the mining and quarrying sector impacts the output of other sectors to increase overall economic growth.

El objetivo fue identificar mediante análisis in silico los genes a los cuales se unen los miR-146a, miR-146b y miR-155 y, analizar las rutas metabólicas en las que intervienen durante la infección con tuberculosis. Para el análisis se utilizó: miRBase, UniProtKB, TargetScan Human, miRDB y miRTarBase. El miR-146a interacciona o se une a genes importantes en la adhesión celular y el proceso de fagocitosis (CLDN16 y ATP6V1C2, respectivamente) (P, 0.05), esta interacción podría tener implicaciones importantes en la patogénesis de la tuberculosis o enfermedades relacionadas. Los resultados de este trabajo sugieren que la activación de mecanismos moleculares específicos en respuesta a la tuberculosis está regulada por los miR-146a, miR-146b y miR-155. Los genes con los cuales los miR-146a y miR-155 interaccionan o se unen, están involucrados en la respuesta inmune y en procesos celulares imprescindibles durante una infección por tuberculosis.
Устойчивость предприятий в корпоративной структуре строительной группы: содержание и определяющие факторы
Authors: Желиховский Денис Олегович
Published: January 2024

Развитие строительных комплексов в современных экономических условиях обусловлено существенным влиянием негативных факторов внешней среды вследствие геополитических и макроэкономических кризисных явлений. Возникает необходимость в развитии подходов к стратегическому управлению строительными предприятиями и их объединениями с целью повышения устойчивости и конкурентоспособности на внутренних и внешних рынках. Специфика развития современных предприятий инвестиционно-строительного комплекса (ИСК) заключается в комплексности подхода к созданию готовой строительной продукции, заключающегося в усложнении производственно-хозяйственных связей между предприятиями, увеличении числа участников производственных процессов в строительстве, развитии механизмов корпоративных объединений отдельных субъектов ИСК. В качестве объекта стратегического управления в рамках ИСК целесообразно рассматривать строительные группы как ключевую форму корпоративного внутриотраслевого взаимодействия предприятий различной специализации, позволяющую в наибольшей степени реализовать возможности внедрения механизмов гибкого организационного моделирования как на уровне строительной группы, так и в рамках функционирования отдельных ее участников. Решение задач стратегического управления строительной группой должно реализовываться при выполнении условий максимизации уровня стратегического развития при обеспечении достаточного уровня генеральной устойчивости строительной группы. Ключевым аспектом разработки подхода к формированию и развитию подходов стратегического управления является определение факторного пространства, оказывающего влияние на процессы функционирования управляемой системы в целом и, как следствие, на уровень ее организационно-экономической устойчивости. Результаты проведенного исследования позволили автору сформировать структуру генеральной устойчивости строительной группы с указанием взаимосвязи отдельных элементов устойчивости и ключевых факторов-индикаторов устойчивости на каждом уровне управления. Представленная структурная модель генеральной устойчивости строительной группы способствует развитию методического инструментария при реализации системного подхода к стратегическому управлению строительными группами и предприятиями, функционирующими в их составе.
