Indonesia's Economic Strength in the Middle of Global Economic Strength. Indonesia is ranked 16th with a GDP of US$ 1.2 trillion or 1.2% of world (global) GDP. Based on the summary of data from the International Monetary Fund (IMF), referring to the prediction of the amount of Gross Domestic Product (GDP) of each country, Indonesia is included in 4 (four) Asian countries as the top five ranks which will begin to dominate global economic power. In the infographic included with the title “Continental Shift: The World's Largest Economy of All Time”, there are about 11 names of countries from four continents, including Indonesia representing Asia along with China, Japan and India.

In 2011, as the world population map changes, it is predicted that Indonesia will get a demographic bonus where the population of Indonesia will be dominated by the productive age group, so that it will be ranked as the 12th world economic power. The research was carried out by the international team in the journal The Lancet (2020) under the title Fertility, mortality, migration, and population scenarios for 195 countries and territories from ‎2017 to 2100: forecasting analysis for the Study of the Global Burden of Disease. The study noted that Indonesia will be in the 12th position in the world starting in 2050, meaning 30 years from now. Meanwhile, in 2030, it will rank 14th in the world economy. ️

Indonesia is the only ASEAN country that is a member of the G-20 (or the 20 Group). The countries in this group consist of 19 countries plus the European Union; controls 75% of world trade. The G20 is a collection of countries with the largest economic power in the world. Currently, Indonesia's position is 16th based on the world's largest GDP or Gross Domestic Product (GDP). The magnitude of this has resulted in Indonesia being now included in the association of 20 large countries that have a "large GDP" or better known as the "group of 20" (G20).

Published: November 2022

There has been a dramatic rise in the prevalence of atopic diseases in both developed and developing countries, especially children. Atopic dermatitis (AD), a specific form of eczema, is the most common chronic inflammatory skin disease. AD has significant morbidity, and the prevalence of the disorder has been increasing over the past few decades. This study was aimed at reviewing in detail AD in pediatric patients in Saudi Arabia. PubMed, Web of Science, Science Direct, Elton B Stephens Company, and Cochrane library were searched. Study articles were screened by title and abstract using Rayyan Qatar Computing Research Institute then a full-text assessment was implemented. A total of 14 studies including both sexes and 0-18 years of age patients diagnosed with AD were included in this review; more than half were males. We estimated a widely ranging prevalence around the different districts of Saudi Arabia, which may be explained by the marked variations in topographical, meteorological, and climatic conditions. Distribution of allergens may vary with different geographic areas, local climates, environments, and lifestyles; critical regional variations in allergic disease prevalence can be observed. Also, we estimated an increasing prevalence of AD among children in Saudi Arabia with elevating stress levels of both the patients and the parents and a significant effect on their quality of life.

Published: November 2022

This study investigates reservoir quality for the Middle–Late Eocene Pila Spi Formation in Shaqlawa (Sarkand) and Gulley Keer (Shekhan) areas in Kurdistan Region of Iraq. Lithologically, the Pila Spi Formation in the studied sections is composed of limestone, dolomite, dolomitic limestone, chalky limestone, and marl. The thickness of the formation is about 102m and 200m in Sarkand and Gully Keer sections respectively. In order to evaluate the reservoir characterization of the studied formation, different techniques such as a microscopic study and core plug analysis were used. The Pila Spi Formation is characterized by several pore's types namely; vugs, moldics, channels, interparticles, fractures, boring, fenestral, and intragranulars. Several diagenetic processes were also recognized such as dolomitization, pressure solution, stylolization and dissolution. Based on the petrographic study, the lower part of the formation in Sarkand section has a porosity average of 8%, while it has an average of 21% and 17% in middle and upper parts. In Gulley Keer section, the porosity values of the formation are about 9%, 17, and 19%, in the lower, middle and upper part, respectively. The Scanning Electron Microscope (SEM) study shows almost the same porosity values, and the pore's sizes are between micropore to mesopore for the studied sections. Furthermore, the results of the core plugs analysis are roughly in agreement with optical assessments since the measured porosity values from Sarkand section are 8%, 18.5%, and 18% for lower, middle and upper parts, respectively. The porosity values of Gulley Keer section for lower, middle and upper parts of the studied section are 2.5%, 17.25%, and 22.5%, respectively. Consequently, the results revealed that the Pila Spi Formation has a good porosity except the lower part. In regards with permeability, the measured values of permeability displayed an avenge of 0.109md and 0.6698md for Sarkand and Gulley Keer respectively in which suggested fair to good permeability.

Published: November 2022

Thermal plasma spraying method was used for coating the pre-prepared surfaces of turbine blades. Nickel (Ni) was used as a base material with a fixed percentage of alumina (5%Al2O3), and (5,10,15,20,25%) of Boron carbide (B4C) as reinforcement material. Cermet powders were mixed for one hour, then the coating bases of steel type (316L) were prepared and roughened using sandblasting to increase the adhesion strength between the coated materials and the base. The bonding material represented by (Ni-22% Cr-10%Al-1%Y) was sprayed with a thickness of (150µm), and then the base and reinforcement material were sprayed with a thickness of (350-400 µm). Thus, the final thickness of the prepared samples was (550-500 µm). After that, the samples were sintered at 900°C for two hours. The hardness test was applied to the samples, indicating the best hardness after sintering at (25%) reinforcement ratio of 590Hv. As for porosity, its lowest value was obtained at 7%, while the best value of adhesion strength was obtained after sintering at (25%) of B4C. However, the results of the scanning electron microscope (SEM) showed the weakness and the presence of pores in the coating layers at the low percentage of reinforcement. While the mechanical and physical properties were improved with the increase in the percentage of reinforcement to reach the best at 25% of B4C.

Published: November 2022

Contamination from outgassed materials, venting, leaks, and impinging thruster plumes can cause deleterious effects to sensitive experiments on the International Space Station. In low Earth orbit, intermolecular collisions between neutral contaminants and ions in the ambient ionospheric environment result in an elevation in the local charged particle density through a process called charge exchange (CEX). Of particular concern to spacecraft engineers is the acceleration of these ionized neutrals to sensitive negatively charged spacecraft surfaces. The increase in plasma density due to CEX can be readily measured using plasma diagnostics such as electrostatic energy analyzers. These instruments are capable of monitoring charged particle flux and are sensitive enough to measure small changes in local density, thus allowing for the detection of CEX contaminants. The automated plume sentry (APS) is one such instrument, and it has successfully detected CEX plasma generated by the planned ammonia venting of the external active thermal control system. The data collected by the APS will support the development of improved computational models to predict the propagation of outgassed materials and plumes in the ionosphere and complex gas–surface interactions resulting in spacecraft surface contamination.
Experimental Investigation of the Coupling Process of Laminar Wings at Their Tips
Authors: Grund Thomas , Weiss Julien
Published: November 2022

In this paper, we address the influence of geometric parameters relevant to the lateral in-flight coupling of two laminar wings at a Reynolds number of [Formula: see text]. The aerodynamic loads are determined by means of detailed force and pressure measurements for different wing spacings and angle-of-attack combinations. When the spanwise spacing between the wings is reduced, increased lift and decreased drag coefficients are noted, which are mainly explained by the alteration of wing-tip vortices. We also show that the gap flow developing between both wings at small distances induces a suction effect, that is, strong lateral forces of opposite signs acting on the two wings. When the angles of attack of both wings are varied for a fixed-wing spacing, a strong interaction between the two wings is found to affect the lift and drag coefficients. The results presented in this paper help understand the changes in aerodynamic loads that occur during the wing–tip-coupling process, and thus may promote the design and operation of such procedures in for future multibody aircraft.
Fuel Cell Hybrid-Electric Aircraft: Design, Operational, and Environmental Impact
Authors: Scholz Anna E. , Michelmann Johannes , Hornung Mirko
Published: November 2022

To reduce the environmental footprint of the aviation industry, aircraft with new propulsion systems are increasingly under consideration. In this paper, the potential of a fuel cell hybrid-electric aircraft (FCHEA) powered by hydrogen and kerosene is assessed. First, the methodology for the conceptual design of a single-aisle short-range FCHEA is developed and presented. Then, the environmental impact of this aircraft on its design mission is determined by means of a one-dimensional climate model and the climate metric sustained global temperature potential with a time horizon of 100 years. To complete the picture, the fleet adoption of the FCHEA concept is determined with the help of a fleet system dynamics model taking future air traffic development, fleet age, and production capacities into account. This makes it possible to analyze the potential of FCHEA to improve the environmental footprint of aviation considering the operational environment in the global aviation market. The results show that for a single FCHEA powered by liquid hydrogen produced via electrolysis with renewable energies, climate impact reductions of 15.2–17.8% can be achieved. The fleet uptake of the FCHEA made full use of the available production capacities, but still it was able to serve only 15.8% of total available seat kilometers.
Variation of Acoustic Energy Across Sudden Area Expansions Sustaining a Subsonic Flow
Authors: Gaudron Renaud , Guzmán Iñigo Juan , Morgans Aimee S.
Published: November 2022

The acoustic energy balance of a sudden area expansion is known to be altered in the presence of a mean flow. In this work, Ronneberger’s quasi-steady model describing the acoustic response of a sudden area expansion sustaining a subsonic mean flow of arbitrary Mach number is revisited using the acoustic absorption coefficient, shown to be a function of the inlet Mach number [Formula: see text], cross-sectional area ratio [Formula: see text], and upstream acoustic reflection coefficient [Formula: see text]. These analytical predictions are tested using a two-step numerical strategy, whereby the mean flow variables are obtained using Reynolds-averaged Navier–Stokes simulations and the fluctuating variables are computed using in-house linearized Navier–Stokes equations solvers. The agreement between the analytical model and the numerical results is found to be excellent for all geometries, mean flows, and acoustic boundary conditions investigated. The generation of acoustic energy by the flow expansion is observed analytically and numerically for high-Mach-number flows undergoing a slight sudden area increase for given acoustic boundary conditions. Conversely, it is found that substantial acoustic energy damping occurs across sudden area expansions characterized by a wide range of parameters [Formula: see text]. Moreover, entropy and vorticity fluctuations are found to be generated at the sudden area expansion, but entropy fluctuations are shown to have a negligible impact on the acoustic response of the area expansion at low and intermediate Mach numbers. Finally, the analytical model is found to be reasonably accurate up to Helmholtz numbers [Formula: see text], corresponding to the frequency range of many industrial applications.
Vibration Behavior of Dual-Rotor Caused by Maneuver Load and Intershaft Bearing Defect
Authors: Gao Tian , Yuan Simin , Liu Pengfei , Cao Shuqian
Published: November 2022

This paper concentrates on the vibration amplitude modulation and frequency modulation behavior of a dual-rotor system induced by the maneuver load and defective intershaft bearing. The motion equations of a dual-rotor system are presented by considering the intershaft bearing force with a local defect of the outer raceway and the maneuver load of a barrel-roll flight. The fourth-order Runge–Kutta method is employed to study the vibration responses of the dual-rotor system, which are reflected by the time history curves, the bearing contact force curves, and the Hilbert envelope spectra. It is shown that the rotor responses display impulse vibrations due to the defective intershaft bearing; and the corresponding Hilbert envelope spectra contain defect characteristic frequencies, multiple defect frequencies, side frequencies, and modulation frequencies. The results reveal the frequency modulation behavior of the impulse vibrations induced by the rotating speed ratio and the amplitude modulation behavior influenced by the maneuver load, the bearing defect span, and the rotating speed. Finally, defective intershaft bearing experiments under maneuvering flight are conducted, confirming the availability of the numerical vibration amplitude modulation and frequency modulation behavior. This analysis provides a theoretical foundation for bearing state detection during flight maneuvers.
Smart detection of fractures in formation image logs for enhanced CO2 storage
Authors: Katterbauer Klemens , Al Qasim Abdulaziz , Al Shehri Abdallah , Al Zaidy Rabeah
Published: November 2022

Carbon capture and storage (CCS) has attracted strong interest from industry and the scientific community alike due to the ability of storing CO2 in subsurface reservoirs. Deep saline aquifers may be well suited for the safe and long-term storage given their geological structure. The long term underground storage in saline aquifers depends on variety of interrelated trapping mechanisms in addition to the caprock sealing efficiency. Fractures are commonplace in many geological settings and represent a crucial role for hydrocarbon migrations and entrapment. Fracture impact fluid flow in variety of forms, particularly due to the complexity and varying natures of the fractures, which channel the injected CO2 throughout the reservoir formation. This is especially important for tight gas reservoirs and low permeable cap rock structures whose permeability is primarily characterized by the fault and fractures. This outlines the importance of determining accurately fracture penetration in wellbores for CO2 injection. We present a new deep learning framework for the detection of fractures in formation image logs for enhancing CO2 storage. Fractures may represent high velocity gas flow channels which may make CO2 storage a challenge. The novel deep learning framework incorporates both acoustic and electrical formation image logs for the detection of fractures in wellbores for CO2 storage enhancement and injection optimization. The framework was evaluated on the Pohokura-1 well for the detection of fractures, with the framework exhibiting strong classification accuracy. The framework could accurately classify the fractures based on acoustic and electrical image logs in 98.1% for the training and 85.6% for the testing dataset. Furthermore, estimates of the fracture size are strong, indicating the ability of the framework to accurately quantify fracture sizes in order to optimize CO2 injection and storage.

Authors: Yosef Yosef
Published: November 2022

Having adequate multicultural self-efficacy enables students to get along, learn, and collaborate confidently and harmoniously with culturally diverse peers in any school setting. However, there is only a small number of research on this matter for the dual types of Indonesian secondary schools. The objective of this study was to compare Islamic and public high school students on multicultural self-efficacy. A 36-item Multicultural Self-Efficacy Scale for High School (MSES-HS) measured the multicultural self-efficacy of 246 Islamic and Public high school students in an online survey. It consisted of cultural insight, communication, cultural value, cultural awareness, and flexibility subscales. Results indicated that most of the students’ multicultural self-efficacy in both schools fell from a moderate to the highest level, except for small numbers at a low and a lower level. The current study found that the multicultural self-efficacy levels of Islamic and public high school students were not different significantly. In terms of differences by grade levels and gender, the study indicated similar results. The study highlighted findings to guidance and counseling services and suggestions to expand the investigation.

This study aimed to examine the effect of stress and religiosity on well-being and the role of religiosity in moderating the relationship between stress and well-being during the COVID-19 pandemic. This study involved 1233 Indonesian Muslim students from whom data were collected through a survey by distributing questionnaires online. Data collection was made through surveys by distributing online questionnaires in Bahasa, including The Depression Anxiety Stress Scale-21 (DASS-21), the Short Muslim Belief and Practice Scale (Short-MPBS), and The Warwick-Edinburgh Mental Well-being Scale (WEMWBS). The data analyses included bivariate correlation, multiple regression, and moderated regression analyses. The results showed: 1) There was a negative relationship between stress and religiosity and well-being; 2) There was an effect of stress and religiosity together on well-being; 3) Religiosity moderated the relationship between stress and well-being, which means that the hypotheses were supported by the data. The implication of this study is to strengthen positive psychological theory that various factors that previously could cause anxiety and stress in students do not have a bad impact on causing misery, because religiosity can provide reinforcement so that their welfare is maintained in the midst of difficult conditions.

Kierkegaard e Nietzsche:
Authors: Abe Paulo
Published: November 2022

O presente artigo problematiza a relação entre as análises da Modernidade feitas por Kierkegaard e Nietzsche, buscando por semelhanças que podem dar luz a uma descrição de um mesmo fenômeno. Para tanto, o objetivo primário é analisar as expressões do indivíduo em sua luta contra tornar-se si mesmo, especialmente as que envolvem a inconsciência, o que Kierkegaard chama de “maior de todos os riscos”. Posteriormente, discutiremos as razões e consequências que levarão o indivíduo até a massa. O mesmo percurso será feito com Nietzsche, a fim de analisar o instinto de rebanho e a moral de escravo neste fenômeno social do século XIX. Por fim, procuraremos ver até que ponto ambos discutem o mesmo objeto e até que ponto um é objeto de crítica do outro.
Nietzsche e o pensamento chinês:
Authors: Onofri Wilson Luciano
Published: November 2022

O presente trabalho tem como objetivo analisar a relação da filosofia de Nietzsche com o pensamento chinês. Para tanto, a investigação procurou analisar quatro pontos fundamentais, a saber: uma primeira parte dedicada à investigação sobre o sentido que o tipo chinês ocupa no pensamento de Nietzsche, buscando ressaltar o caráter polissêmico do uso da palavra pelo filósofo para além do caráter estritamente pejorativo, mostrando inclusive uma compatibilidade entre as duas formas de pensamento; uma segunda parte dedicada a história de recepção do pensamento de Nietzsche na China; uma terceira parte sobre a primeira recepção do pensamento de Nietzsche na China no pensamento político de Liang Qichao, em meio ao debate sobre o darwinismo social na China; e uma quarta e última parte dedicada à recepção da filosofia de Nietzsche por meio dos estudos filosóficos de Wang Guowei, responsável pela divulgação do pensamento de Nietzsche na China, mais especificamente nos estudos sobre a relação entre a filosofia de Schopenhauer e o pensamento de Nietzsche.

THE CERAMIC ASSEMBLAGE DATING TO THE LAST QUARTER OF THE 17th - EARLY 18th CENTURIES FROM THE EXCAVATIONS OF THE NEW PRIKAZY BUILDINGS IN THE MOSCOW KREMLIN
Authors: Гакель Е. В. , Дзвонковский С. Л. , Коваль В. Ю.
Published: November 2022

В статье приводятся статистические данные об узко датированном керамическом комплексе Нового времени из раскопок Института археологии РАН, при которых был открыт фундамент фасада здания Новых Приказов (1675-1770 гг.). Комплекс демонстрирует хронологический срез в бытовании различной посуды, распространенной на рынке Москвы и использовавшейся в быту служителей Приказов. Своеобразна структура типов использовавшейся посуды, соотношение функциональных форм керамики (горшков, кувшинов и т. п.). Впервые встречена в Москве форма светлоглиняных кувшинов-корчаг.

The paper provides statistical data on a narrowly dated ceramic assemblage dating to the modern era from excavations conducted by the Institute of Archaeology, RAS, that uncovered a foundation pit of the New Prikazy building facade (1675-1770). The assemblage demonstrates a chronological section in use of various vessels frequently found in the Moscow market and commonly used by the Prikazy officials. The typology of the vessels used and percentage shares of various functional forms of the vessels (pots, jars, etc.) is quite singular. Large earthenware ewers made from light clay have been found in Moscow for the first time.

Published: November 2022

Скальные погребения Северного Кавказа образуют особую категорию памятников эпохи средневековья. Они имеют длительную историю изучения. Однако большинство проблем, связанных с их хронологической и культурной атрибутикой, остаются дискуссионными. В статье рассматривается погребение мумифицированного индивида из скального могильника Джалан-Кол I, исследованное методами компьютерной томографии с целью реконструкции особенностей погребального обряда и постановки вопроса о причинах, способствовавших естественной мумификации.

Rock graves in the North Caucasus are referred to a special group of medieval sites. Their studies have a long history. However, most issues related to their chronological and cultural attribution are still controversial. The paper analyzes a grave containing a mummified individual from the Dzhalan-Kol I rock cemetery examined by computer tomography with a view of reconstructing distinctive features of the funerary rite and bringing up an issue of what caused natural mummification.
RHOMBIC SIGNS FROM CHERNOOZERYE II AND PEGAN: ORNAMENTAL INVARIANTS? ATTEMPT TO JUSTIFY AND LOCALIZE THE STYLE
Authors: Шмидт И. В.
Published: November 2022

В исследовании рассмотрена стилистическая общность орнаментальных сюжетов двух кинжалов - из Черноозерья II (Саргатский р-н Омской области; ОМК 9675/702) и погребения Пеган (Макушинский р-н Курганской области; ЧОКМ ОФ-556/1). Пеганский сюжет, основой которого является «цепочка ромбов», представлен инвариантом черноозерского прототипа. Выявленная комплексность аналогии, заключающаяся в знаковом синтаксисе орнаментального текста, форме и морфологии ключевого знака, порядке его графического построения, не может быть случайностью; иллюстрирует близость двух орнаментальных традиций финала палеолита и мезолита, бытовавших на территориях между Средним Прииртышьем и Зауральем. Контакты между указанными регионами теперь находят подтверждение не только в технико-типологических факторах каменных индустрий, но и в стилистике орнаментального оформления костяных изделий. Приведенные аргументы позволяют задуматься над возможностью локализации зоны устойчивого в своем орнаментальном исполнении мотива. Выводы носят предварительный характер. Для уверенных заявлений необходимы дальнейшие исследования (продолжение археологических работ и изучение существующих музейных коллекций) юго-запада сибирского региона.

The study explores stylistical similarity of decorative patterns on two daggers, one from Chernoozerye II (Sargatsky district, Omsk region) and the Pegan grave (Makushinsky district, Kurgan region). The Pegan decorative pattern based on a ‘chain of rhombs’ is represented by an invariant of the Chernoozerye type. The identified complexity of the analogy which manifests itself in sign syntax of the decorative text, the form and morphology of the key sign, the pattern of its graphical layout cannot be incidental as this complexity illustrates similarity of two decorative traditions that existed in the final stage of the Paleolithic and the Mesolithic and were common in the areas between the Middle Irtysh region and the Trans-Urals. The contacts between these regions are now confirmed not only by technical and typological factors of lithic industries but also by stylistics of decorative patterns on bone items. These reasons allow us to attempt to localize the area where the ornamental representation of the motif is constant. The conclusions provided are preliminary. For these statements to be more valid, it is necessary to have follow-up studies (continue archaeological research and study available museum collections) in the southwestern part of the Siberian region.

Published: November 2022

In order to achieve operational and strategic goals, a technical service enterprise, with the help of management principles, affects management facilities, resources, equipment, machinery, technologies, personnel, customers and partners. Despite the relative stability of the content and structure of the principles of enterprise management, they can be implemented in various ways and are subject to changes depending on the state and trends of environmental development. The article is devoted to clarifying and supplementing the number and interrelationships of management principles of technical service enterprises. It uses methods of analysis and synthesis, induction and deduction, as well as classification, and the tools are binary matrices that provide for the joint use of qualitative features of the studied management principles and their dichotomies. The results obtained make it possible to reduce costs, time, as well as lost profits in the field of technical service due to a clear structuring of management principles by levels of enterprise management and positions provided for by its staffing schedule.
Labor capital development of the region in the focus of sociological research: factors and problems
Authors: Karimov A. G. , Selivanova S. S. , Fatkullina R. G.
Published: November 2022

The presented work analyzes the features, problems and factors of labor capital development of the Republic of Bashkortostan based on the data of a sociological study conducted by the Institute for Socio-Economic Research of the Ufa Federal Research Center of the Russian Academy of Sciences in 2021. A number of problems faced by the able-bodied population are considered, including: a relatively low standard of living of the population, which hinders the provision of the quality of life and professional productivity of workers; gender inequality in the distribution of labor incomes of the population; the predominance of negative assessments of the able-bodied population of their physical condition, the quality of their leisure and vacations; discrepancy between the high qualification of employees and the functions performed, which does not allow them to fully realize their labor potential in the workplace. Particular attention is paid to the analysis of values that prevail in the minds of the able-bodied population and determine their labor behavior, and as a result, have a negative impact on the formation of labor capital. Thus, it was revealed that the value orientations of the population of the Republic of Bashkortostan are typical for countries of “catching up” development. In this regard, the authors substantiate the necessity of cultivating the values of rationality of financial thinking, equality, self-expression and autonomy, as well as improving institutions that support these values in society. These values act as factors in the formation of high-quality labor capital in the conditions of modern Russia
