Justification of safety measures at the construction of territories over old underground mining by the results of complex researches
Authors: Usanov S. V. , Usanova A. V.
Published: January 2021

The area of deformation of the earth’s surface from underground mine workings is generally called the undermined territory. However, the conditions for undermining the surface are very diverse, and therefore the surface deformation takes place with a wide range of features. This creates difficulties for determining the possibility of development, expertise in choosing safety measures, lack of unification of research methods and results, as well as a significant gap in the expectations of developers from the results of the study and design requests. Such gaps are due to the fact that it is impossible to build direct relationships between the qualitative and quantitative characteristics of the displacement process, as well as to relate them to the structures of buildings. On the example of the study of the Shershnevskoye field by geophysical methods, structural changes of the surface layer to a depth of 12 m were evaluated. Identified areas of the alleged existence of old vertical and horizontal mine workings. The authors have proposed a solution to the relationship of the dependences of qualitative and quantitative characteristics by compiling ratings of the developed areas, which will provide a connection with the parametric characteristics of buildings and structures under construction. A number of necessary general and special safety measures are suggested for the operation of the developed areas from old mines.

Published: January 2021

The purpose of this work is to justify and selection of a safe and effective option of the technology for experimental block during the pilot development of the «Skalistoe» deposit. Based on the researches determined that the projected system for the development of sub-floor caving with the accepted parameters does not guarantee the completeness of the extraction of reserves and the efficiency of mining. Project indicators for ore extraction using the technology of sub-floor caving with face ore output are overstated and difficult to achieve in these mining and geological conditions (a combination of low width and insufficiently steep angle of incidence of the ore body); The projected scheme for the delivery and transportation of rock mass is characterized by a significant amount of excavation, increased costs for the transportation of ore and is impractical in conditions of low productivity of the mine. For low power and not enough steep angle of incidence of the field with a high content of useful component, the most suitable options are the chamber development system, the system of sub-floor caving and horizontal layers. Based on this, seven technically rational variants of development systems were constructed: five variants of a sub-floor-chamber development system with the subsequent collapse of the pillars and two variants of a horizontal layer system with a dry (rock) backfill. For the conditions of mining the «Skalistoe» deposit according to the results of economic and mathematical modeling, the optimal technology for profit attributed to 1 ton of redeemable balance of ore reserves is a variant of the technology of sub-floor-chamber excavation with dual chambers, mechanical production of ore with remote control load-andhaul machines and subsequent the collapse of pillars, as having the highest profit by decreasing volume of preparating works on the block by 34%, the cost of ore mining by 12%, losses and dilution of ore by 2 and 2,9 times, accordingly. In particular, the proposed scheme for the delivery and transportation of rock mass can reduce the volume of tunneling by 25% and the average transportation length by 10-15% compared with the projected scheme.
Application of resource-saving principles at breaking of strong fractured ores by blasthole ring charges
Authors: Smirnov A. A. , Baranovskiy K. V. , Rozhkov A. A.
Published: January 2021

During underground mining of deposits of valuable non-metallic raw materials, nonferrous and precious metal ores, the problem of their overgrinding as a result of blasting is quite acute. Overgrinding of valuable non-metallic raw materials leads to an actual decrease in the yield of concentrates or final products, due to the rather stringent requirements of the enrichment technology for the conditional size of the piece and the structural safety of the useful component. Non-ferrous and precious metal ores represented by strong rocks are characterized by the effect of increased concentration of ore minerals in small classes of ore. Due to the process of segregation on ore drawing, small fractions in significant quantities accumulate on the lying side of the goaf and its unevenness. Such ore with a high content of useful component requires additional technological measures for its extraction or is simply lost. Consequently, the development of technological methods for managing the quality of products of a mining enterprise and methods for increasing the completeness of extracting mineral resources are an urgent scientific and technical task. To solve it, an analysis of theory and practice in the study area was carried out, which showed that the existing methods for additional extraction of fine ore fractions in mining systems with an open goaf are laborintensive and resource-intensive, not universal, ineffective and often not safe. It is rational to create conditions for reducing the yield of fine fractions already at the stage of ore blasting As a result, determining parameters principles for breaking technology of strong fractured ores are proposed. Developed guidelines and recommendations for blasthole ring charges. Dependences the technical and economic indicators of ore explosive blasting from its structural and technological parameters are obtained.
Flotation of dispersed gold drops in melts as an element of technological scheme of enrichment
Authors: Amdur A. M. , Pavlov V. V. , Fedorov S. A.
Published: January 2021

A significant part of gold reserves is represented by microand nanodispersed particles in natural deposits and in technogenic formations. In order to extract microdispersed gold particles by existing enrichment methods, they must be enlarged. This is possible in the process of heating and melting the material by flotation. As a result, the flotation of gold drops in the melts becomes an element of the enrichment scheme. It includes grinding the materials and enrichment by gravity methods after it has cooled. Usually flotation is analyzed as one of the technologies for mineral processing. But it is based on the complex and insufficiently studied physicochemical phenomenon of swimming bodies of higher density than that of a liquid on its surface under the influence of interfacial tension forces. Therefore, flotation refers not only to solid, but also to liquid substances. The conditions and mechanism of the flotation of gold and sulfide drops in oxide melts are analyzed. It was found that the flotation of gold drops in melts leads to their significant enlargement and proceeds at rather high rates. The process of passing a gas bubble through the interphase boundary of two immiscible liquids is considered using the example of a matte-slag system and the conditions for a matte drop to float together with a bubble. The scale of solving these problems is determined by the fact that they expand the idea of flotation of drops in melts as a stage of mineral processing in which valuable components are in a dispersed state.
Accounting of modern geodynamic movements in normative documentation
Authors: Kaiumova A. N. , Balek A. E. , Ozornin I. L.
Published: January 2021

In article the actual problem of updating of the current legislation on designing for conformity to modern representations about an array of rocks is designated. Modern geodynamic movements play an important role in the formation of hazardous and emergency situations in surface and underground industrial and social facilities. Currently, in the regulatory documentation for the design of modern geodynamic movements are attributed to separate so-called areas of development of natural and technological processes, so the processes arising under the influence of modern geodynamic movements, are studied only for objects of high responsibility and only on additional request of the task, which is prepared by the customer. Prevention of dangerous development of building object destruction is possible at a stage of designing of constructions at performance of engineering researches. In most cases, engineering-geological and engineering-geodetic surveys are conducted without taking into account the factor of modern geodynamics, which is especially unacceptable in the design of social and industrial facilities, to which increased safety requirements are imposed. At present, the requirements of the standards do not fully correspond to the modern concept of rock mass, mobility of the upper crust of the Earth, which significantly complicates their application in practice. By results of researches it is revealed a number of the reasons of a deviation from requirements of standards for increase of safety of new building or operation of already existing responsible objects taking into account deformation processes under the influence of modern geodynamic movements.
To the problem of reconstruction Praetextatus’ activities from his private and sociocultural life (by epigraphic sources)
Authors: Petrova Maya
Published: January 2021

The paper shows how with the help of epigraphic sources (CIL VI, 1779, 1779a, 1778, 2145, 1777) it is possible to reconstruct individual events in the private and public life of Vettius Agorius Praetextatus (310/320 – 384), the prominent statesman, scientist, representative of the Pagan party in Rome of the Late Antiquity. This article also seeks to recreate his personal qualities, as well as to reveal the attitude towards him of his closest circle (both Pagan and Christian).
‘Metaphysics’ and ‘Phenomenology’ in Plato (the “Phaedo”)
Authors: Protopopova Irina
Published: January 2021

The article considers the correlation between the ‘metaphysical’ and ‘phenomenological’ approaches in Plato’s “Phaedo”. Here, the ‘metaphysics’ refers to philosophical judgments that are considered as certain external principles that are not directly related to the philosopher’s ‘work of consciousness’. The ‘phenomenology’, on the other hand, refers to the specific philosophical experience of observing one’s own ways of grasping things in the immediate reality of awareness. At the beginning of the dialogue, in the so-called ‘defense of Socrates’, he first offers several premises that are accepted as axioms by his interlocutors and, secondly, he describes a philosophical purification as the ‘gathering of the soul’, which results in a confusion of ideas about the soul as either separated and existing after death or ‘being collected in itself’ in the process of philosophical, metaphorical ‘dying’. The first and the third arguments for the immortality of the soul can be considered as ‘metaphysical’, based on analogies, and the second and the forth, as ‘phenomenological’, based on the practice of contemplation of ‘eide in themselves’ by the soul ‘in itself’. It is concluded that Plato’s eide do not appear due to induction or deduction and are not a doubling of general concepts, as Aristotle believed, but are revealed as a result of some effort to realize one’s own awareness of one’s own grasping of being. This is what is outlined here as the difference between ‘metaphysics’ and ‘phenomenology’.
The Role of Phonons in Stability of Metallic Nanoparticles
Authors: Orlov Vladimir L. , Orlov Aleksey V.
Published: January 2021

A novel model of a metallic nanoparticle is proposed. The model represents the nanoparticle as a hollow sphere. The existence of a nanohollow inside a particle is related to the behavior of phonons. The strain in the walls of a particle when it's heated is calculated utilizing the theory of a thick-walled shell. We show that in the transition to the elastic state, the expansion strains at the surface of a nanoparticle become sufficient for melting. The dependency of melting temperature on the size of a nanoparticle is discussed.
Integration potential of megaregional trade agreements in Asia-Pacific Region
Authors: Tomilov Mikhail V.
Published: January 2021

Since the beginning of the XXI century, an increase in the number of new regional trade agreements has been recorded. At the same time, their quality content is changing significantly, which has led to the emergence of mega-regional trade agreements (MRTА). This process is particularly active in the fast-growing Asia-Pacific region (APR), where initiatives for the creation of the Trans-Pacific Partnership (TPP), The Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP), the Regional Comprehensive Economic Partnership (RCEP) and the Free Trade Area of Asia-Pacific (FTAAP) have emerged during this period. However, it is still difficult to assess their effectiveness in terms of obtaining potential positive economic results. The article's aim is to assess integration potential of APR MRTA within two stages. At the first stage, methods of econometric analysis were used to determine the economic proximity of their participants. At the second stage, a gravitational model of foreign trade was constructed to assess all trade barriers (tariff, non-tariff, etc.) within the group of integrating countries. Based on the results of integration potential assessment, the author defines the most promising existing multilateral integration associations in the Asia-Pacific region, as well as a hypothetical group of countries in the region, which will receive the greatest trade and economic effects as a result of integration under the assumptions adopted in the study. In addition, an approach to assessing the integration potential and determining the optimal composition of the countries participating in MRTA based on the criteria of proximity of their economic development levels and the size of trade barriers within the group is proposed, methodically justified and implemented.

Published: January 2021

Modern technologies have a large-scale impact on the transformation of functions, tools and methods of management as well as managers' competencies, updating the question of what will management be like in the near future. The article presents an overview of the main management development trends, outlining the emerging management development paradigm in today’s digital age.
The paper analyses the works of the leading foreign and Russian researchers in the field of management, as well as those selected by the keywords. In total, more than 100 publications aimed at identifying and theoretical understanding of management development trends in the digital economy were reviewed.
It is shown that the concept of management in the digital era develops dynamically, but the contours of the emerging paradigm provoke professional discourse and experiments. The diversity of researchers' views on the future of management is systematized from the perspectives of organizational business models and strategic priorities of the companies, which seems to be the key aspects of management, ensuring a holistic perception of the business and showing the direction of its transformation in response to environmental challenges. Based on these findings, new requirements for the competencies of modern managers are given. It is also shown that well-known consulting companies introduce new complex indicators of effective companies’ management systems. The identified trends of the modern management development as well as the new competencies of managers, which could be of interest to the researchers and management practitioners, require further analysis, as technologies and management practices evolve.
Performance of estimators of quadratic variation based on high frequency data—empirical review
Authors: Gayomey John , Kostin Andrei V.
Published: January 2021

Recently, advances in computer technology and data recording and storage have made high-frequency financial data readily available to researchers. As a result, the volatility literature has steadily progressed toward the use of higher-frequency data. However, the move towards the use of higher-frequency financial data in the estimation of volatility of financial returns has resulted in the development of many realised volatility measures of asset return variability based on a variety of different assumptions and functional forms and thus making theoretical comparison and selection of the estimators for empirical applications very difficult if not impossible. This article provides an empirical review on the performance of estimators of quadratic variation/integrated variance based on high-frequency data to aid their application in empirical analysis. The result of the review shows that no single estimator works best in all situations; however, the more sophisticated realised measures, in particular the TSRV and KRV, are superior to the other estimators in terms of their estimation accuracy in the presence of market microstructure noise.

Authors: Rodrigues Fernanda Odete Souza , Silveira João Vítor Flores , Costa Marina Santos , Torres Giovanna Nogueira , De Faria Iwens Moreira
Published: January 2021

Esse artigo objetivou analisar estudos publicados sobre a influência da prática da amamentação na redução do risco da neoplasia mamária. Os artigos selecionados foram pesquisados nas bases de dados PubMed, LILACS, Scielo e Google Acadêmico e publicados entre os anos 2002 e 2020. Pouco tem sido estudada a relação entre câncer de mama e amamentação. É possível que a sucção da mama, realizada pelo recém-nascido, promova alterações hormonais que repercutam sobre o desenvolvimento dessa doença. Entre os 11 artigos revisados, 10 atestaram o papel da amamentação na redução do surgimento de câncer de mama, tendo esta redução sido maior quanto mais longo o tempo da oferta de leite materno. Apesar dos inúmeros benefícios, as taxas de aleitamento materno no Brasil ainda são insuficientes. Tendo em vista o impacto positivo dessa prática sobre a redução da incidência do câncer de mama, orientações às gestantes sobre a relevância e o manejo desse processo se fazem necessárias.

Published: January 2021

Objectives:

Nurses are an integral team member in intensive care units (ICU) and can play important role in facilitating the organ donation process. Hence, the sensitisation of these nurses is important. The aim of the study was to assess the effectiveness of a computer based self-instruction module (CBSIM) in terms of improving the knowledge and acceptability of nurses in relation to organ donation.

Materials and Methods:

In this prospective study, 56 nurses working in an ICU were enrolled using the total enumeration technique. After filling up of the demographic profile, nurses attempted online pre-test, containing 20 randomly selected multiple-choice questions (MCQs) from a validated and pre-tested question bank containing 150 MCQs. The intervention consisted of self-paced CBSIM containing nine modules on different aspects of organ donation. The intervention was completed in 25 ± 5 days, followed by an online post-intervention test. Acceptability of the CBSIM by nurses about organ donation was assessed as a secondary outcome on a 5-point Likert scale.

Results:

A significant gain in knowledge scores was observed after the CBSIM (4.9 ± 1.14 vs. 7.35 ± 1.34, P < 0.001) with high acceptability of CBSIM by most of the nurses (59.2%).

Conclusion:

CBSIM was effective in improving the knowledge of nurses related to organ donation and highly acceptable to most of the nurses working in ICU. Hence, CBSIM can be used as a method of learning for nurses.

Evidence for Polarity- and Viscosity-Controlled Domains in the Termination Reaction in the Radical Polymerization of Acrylonitrile
Authors: Lin Xiaopei , Ogihara Tasuku , Kato Tatsuhisa , Nakamura Yasuyuki , Yamago Shigeru
Published: January 2021

The termination mechanism in the radical polymerization of acrylonitrile (AN) was determined by the reaction of structurally well-defined polyacryronitrile (PAN) chain-end radical 1a and PAN-end mimetic small model radical 1b. The contributions of three mechanisms, i.e., the disproportionation (Disp), the combination by carbon-carbon formation (CC-Comb), and the combination by carbon-nitrogen bond formation (CN-Comb), were unambiguously determined. The CN-Comb pathway was experimentally proved for the first time. The selectivity between Disp and CC-Comb showed a good correlation with the viscosity and temperature, and the Disp selectivity increased as the viscosity increased, as previously reported for the termination of other monomers. In contrast, CN-Comb is insensitive to viscosity but sensitive to polarity; the selectivity decreases as the polarity of the media increases. The results strongly suggest the presence of two domains in the termination reaction, namely, the polarity- and viscosity-controlled domains. CN-Comb product 5 was stable under the polymerization conditions but decomposed to Disp and CC-Comb products at high temperatures. Therefore, care must be taken in the processing step, such as the molding process, because the physical properties could be altered due to changes in the Disp and CC-Comb compositions.
Leveraging Neural Networks and Genetic Algorithms to Refine Electrode Properties in Redox Flow Batteries
Authors: Tenny Kevin , Braatz Richard , Chiang Yet- Ming , Brushett Fikile
Published: January 2021

Redox flow batteries are a nascent, yet promising, energy storage technology for which widespread deployment is hampered by technical and economic challenges. A performance-determining component in the reactor, present-day electrodes are often borrowed from adjacent electrochemical technologies rather than specifically designed for use in flow batteries. A lack of structural diversity in commercial offerings, coupled with the time constraints of wet-lab experiments, render broad electrode screening infeasible without a modeling complement. Herein, an experimentally validated model of a vanadium redox flow cell is used to generate polarization data for electrodes with different macrohomogeneous properties (thickness, porosity, volumetric surface area, and kinetic rate constant). Using these data sets, we then build and train a neural network with minimal average root-mean squared testing error (17.9 ± 1.8 mA cm−2) to compute individual parameter sweeps along the cell polarization curve. Finally, we employ a genetic algorithm with the neural network to ascertain electrode property values for improving cell power density. While the developed framework does not supplant experimentation, it is generalizable to different redox chemistries and may inform future electrode design strategies.

EFFICIENCY OF POLITICAL RHETORIC IN THE VIEWS OF ALBERT O. HIRSHMAN
Authors: Михайлова Елена Евгеньевна
Published: January 2021

В русле воззрений американского теоретика Альберта Отто Хиршмана рассмотрены условия эффективности современного политического дискурса, в частности, его риторики, тематики и контекста. Показано, как аргументирует Хиршман три варианта реакционной критики, направленной на действия властей. Первый тезис предостерегает о возможном ухудшении результатов, второй - о напрасности усилий, третий - о высокой цене изменений. Несмотря на конфронтацию и полярные прогнозы реформ, в риторике реакционеров и прогрессистов обнаруживается глубокая взаимосвязь. Свобода как возможность интерпретации, равенство интересов и прогресс - таковы базовые ценности политической риторики. Предпринятый Хиршманом анализ полярных жанров политической риторики наводит на мысль о том, как важно непрерывно повышать уровень споров, иметь открытое пространство для диалога, гибкой критики и выразительных средств аргументации.

In line with the views of the American theorist Albert Otto Hirschman, the author considers the conditions for the effectiveness of contemporary political discourse, in particular, its rhetoric, themes and context. It is shown how Hirschman approaches three variants of reactionary criticism aimed at the actions of the authorities. The first thesis warns of a possible deterioration resulting from the changes, the second - claims the futility of efforts, the third - predicts the high cost of changes. Despite confrontation and polarizing predictions of reform, the rhetoric of reactionaries and progressives is deeply intertwined. Freedom as an opportunity for interpretation, equality of interests and progress - these are the basic values of political rhetoric. Hirschman's analysis of the polar genres of political rhetoric suggests how important it is to continuously raise the level of debate, to have an open space for dialogue, flexible criticism, and expressive means of argumentation.
Effects of air temperature and blanching pre-treatment on phytochemical content, antioxidant activity and enzyme inhibition activities of Thai basil leaves (Ocimum basilicum var. thyrsiflorum)
Authors: Le N.L. , Le T.T.H. , Ma N.B.
Published: January 2021

Thai basil leaves (Ocimum basilicum var. thyrsiflorum) have been used in food flavoring
and traditional medicine. Hot-air drying is a convenient and low-cost method to preserve
them for long-term use but causes the loss of their bioactive compounds during the
process. In this work, the effect of pre-blanching on preserving these characteristics of
Thai basil leaves dried at different air temperatures was studied. The antioxidant
characteristics were evaluated by the contents of total phenolics, total flavonoids and total
chlorophylls and the scavenging capacity against 2,2-diphenyl-1-picrylhydrazyl (DPPH)
radicals. In addition, the inhibitory activities against starch-digesting enzymes were
assessed with α-amylase and amyloglucosidase. At the air temperature of 50oC,
antioxidant characteristics of dried leaves with pre-blanching were proven better than
those without blanching and came close to those of the fresh sample. The drying
temperature had more evident effects on inhibitory activities against starch-digesting
enzymes than blanching. These activities of hot-air dried leaves were comparable to those
of the fresh one. This study could provide insights into the integration of blanching and
hot-air drying to preserve medicinal plants.
Punctuation Practice in Early Modern English Scientific Writing: The Case of MS 3009 at the Wellcome Library, London
Authors: Criado-Peña Miriam
Published: January 2021

The study of punctuation has traditionally been overlooked by some scholars for being considered haphazard and unpredictable. In medieval manuscripts, every scribe was free to use their own repertory of symbols. However, the establishment of the printing press along with the proliferation of professional scriveners resulted in a process of standardization of the system in such a way that by the end of the 16th century a repertory of punctuation symbols was fully developed (Salmon 1999: 15; Calle-Martín 2019: 179-200). The present study seeks to examine the punctuation system of a 17th-century recipe book housed in the Wellcome Library in London, MS Wellcome 3009. This paper has therefore been conceived with a twofold objective: a) to assess the inventory of punctuation marks in the text; and b) to analyze the use and pragmatic functions of these symbols.
Personajes masculinos que cuestionan los estereotipos de género y nuevas multialfabetizaciones en los libros álbum: una mirada sistémico-funcional y semiótico-social
Authors: Martínez Mateo Roberto
Published: January 2021

El objetivo de este trabajo es identificar, en dos libros álbum donde los personajes principales cuestionan los estereotipos tradicionales de género masculinos, los recursos verbales y visuales utilizados por el/la autor/a y los ilustradores para estudiar sus sinergias en la construcción del mensaje global en el plano representacional. Mediante un análisis multimodal desde la Lingüística Sistémica Funcional de Halliday (2004) y la Semiótica Social Visual de Kress y van Leeuwen (2006), se identifican las elecciones en el modo verbal y visual adoptadas en cada texto de la muestra y luego se analiza su interacción.Mayoritariamente, ambos modos se complementan para elaborar un mensaje común, aunque, en ocasiones, el peso del modo visual supera al textual en la construcción del significado debido a la complejidad de las imágenes (procesos visuales de acción y reacción, con procesos verbales y mentales). Por ello, es fundamental que los jóvenes reciban instrucción sobre las alfabetizaciones múltiples en la EducaciónPrimaria.

Published: January 2021

Steel is one of the most important bulk materials these days. It is used almost everywhere - from medicine to industry. Detecting this material's defects is one of the most challenging problems for industries worldwide. This process is also manual and time-consuming. Through this study we tried to automate this process. A convolutional neural network model UNet was used for this task for more accurate segmentation with less training image data set for our model. The essence of this NN (neural network) is in step-by-step convolution of every image (encoding) and then stretching them to initial resolution, consequently getting a mask of an image with various classes on it. The foremost modification is changing an input image's size to 128x800 px resolution (original images in dataset are 256x1600 px) because of GPU memory size's limitation. Secondly, we used ResNet34 CNN (convolutional neural network) as encoder, which was pre-trained on ImageNet1000 dataset with modified output layer - it shows 4 layers instead of 34. After running tests of this model, we obtained 92.7% accuracy using images of hot-rolled steel sheets.

Published: January 2021

Introduction. Modern scientific view and analysis of recent studies shows that the study of changes in the physiological mechanisms of the hearing system of a child with hearing impairment, which interact and affect the auditory sensory system, is of great importance to justify the introduction of effective methods of correction of motor disorders. Aim — to test concepts and determine the efficacy of health-forming technologies in the process of adaptive physical education for school children with hearing impairment. Methods: analysis and generalization of data of special scientific and methodical literature; monitoring of information resources of the Internet; sociological methods (questionnaires); method of copying (review and selection of materials from medical records); pedagogical methods (pedagogical testing, pedagogical experiment), methods of mathematical statistics. Results. The concept of health-forming technologies in the process of adaptive physical education of school-age children with hearing impairments is developed and practically tested. The methodological basis of the author’s concept within the framework of the scientific theme was united by three technologies of health formation of different orientation. Conclusions. The received data confirmed that as a result of research and experimental work the efficiency of the author’s concept of health-forming technologies in the course of adaptive physical education of school-age children with hearing impairments was proved. It was based on the development and testing of a conceptual model, and our proposed innovative technologies allowed to ensure the unity and interconnection of the blocks of this model in order to promote healthpromoting activities of children with hearing impairments in the process of adaptive physical education

The relevance of mapping non-anticlinal traps and features of their classifications
Authors: Punanova S.A.
Published: January 2021

The study of hydrocarbon reservoirs in the sediments of sedimentary basins indicates a significant increase in the number of non-anticlinal, complex, unconventional, combined traps, which is currently noted during the discovery of large oil and gas fields with high resources. Based on the analysis of literature sources, the article provides a brief overview of the classifications of traps developed both for regional levels and for local operations in specific oil and gas regions. Examples of the development of subtle extended traps in shale carbonaceous formations are considered.

Published: January 2021

Religious life is very dynamic, especially supported by increasingly advanced technological developments. Of course, the discussion of tolerance must follow the current technological developments because technological developments support it. With the existence of social media, people can gather through an Internet network called the virtual world, both from various countries and religions. This will create vulnerability to religious tolerance because the existence of social media conceivably allows people to show hatred towards other religions, to which according to them is against their religion. Relevant to the studied object, this research is included in the type of library research. Sources of data used in this literature are derived from the Internet, such as YouTube
DAMPAK PENANGKAPAN TERHADAP EKOSISTEM: LANDASAN PENGELOLAAN PERIKANAN BERKELANJUTAN
Authors: Taurusman Am Azbas , Wiryawan Budy , - Besweni , - Isdahartati
Published: January 2021

Kegiatan penangkapan berdampak langsung dan tidak langsung terhadap ekosistem secara dinamis (spasial dan temporal). Perikanan tangkap harus dikelola pada batas yang memberikan dampak yang dapat ditoleransi oleh ekosistem, merupakan prinsip pertama dalam pengelolaan perikanan dengan pendekatan ekosistem (EAFM). Ekosistem merupakan unit organisasi biologi dimana terjadi hubungan fungsional antara komponen-komponen biotik dan lingkungan abiotiknya pada suatu area tertentu (ecological boundary). Penangkapan berdampak terhadap ikan target, non-target (bycatch), serta habitat (lingkungan), yang diindikasikan oleh degradasi populasi (kematian) ikan target dan non-target, degradasi (kerusakan) fisik habitat, dan pencemaran lingkungan perairan. Pada gilirannya akan mengakibatkan terjadi degradasi dinamis struktur (jumlah jenis, kelimpahan, biomassa) dan fungsi ekosistem (reproduksi dan rantai makanan). Intensitas dampak penangkapan ditentukan oleh karakteristik kegiatan penangkapan dan kondisi sumberdaya ikan. Suatu analisis terintegrasi dengan memperhitungkan parameter-parameter tersebut diperlukan dalam studi dampak penangkapan terhadap ekosistem. Dalam kerangka EAFM terdapat solusi teknologi dan manajemen untuk mengatasi dampak penangkapan yakni: perbaikan teknologi, pengendalian input-output, manipulasi ekosistem, dan pengelolaan berbasis hak (right-based).
