Citric Acid as an Effective and Safe Fixing Agent in Vegetable Tanning Process of Goatskin
Authors: Rosiati Nur Mutia , Udkhiyati Mustafidah
Published: April 2023

Formic acid is known as a fixing agent in vegetable tanning process but this material is corrosive and irritant. Citric acid has the potential to be developed as an alternative fixing agent. This research aims to study the ability of citric acid as an alternative fixing agent in the tanning process, especially vegetable tanning of goatskin. The tanning process was carried out by the drum method. Pickled goatskins were tanned with mimosa and then fixed with citric acid. The concentration of citric acid varied from 1%; 1.5%; 2%; 2.5%; to 3%, to determine the optimum concentration. A fixing agent of 2% formic acid was used as a control. The results show that the control skin had similar characteristics to the treated skin. Physical properties of T4 have met the standard of SNI 0253-2009. It can be concluded that the optimal concentration of citric acid that can be used as an alternative fixing agent in vegetable tanning process of goatskin is 2.5%.

Toxic metal ions present in environmental water samples and other samples need to be detected for their removal. The detection of trace metal ions using an ion selective electrode (ISE) holds great significance in analytical chemistry. A 4-vinyl pyridine-ethyl acrylate copolymer-polyvinyl chloride (VE-PVC) based polymeric matrix (electrode) has been fabricated by free radical bulk polymerization method which is an example of a green and sustainable method capable of detecting Ni2+ ions even in trace amounts. To fabricate the polymeric matrix (electrode) (PME), VE has been used as an ionophore. Further, the effectiveness of Ni2+ ion ISE has also been investigated in the presence of surfactants and detergents. Its performance has also been analyzed in the presence of plasticizers. The electrode is found to be very useful for the estimation of Ni2+ ions using ethylenediaminetetraacetic acid by potentiometric titration and also in the estimation of presence of Ni2+ ions  in water. Compared to other metal ions, the fabricated membrane electrode developed in this work has been found to show efficient and better selectivity towards Ni2+ ions.
Evaluation of Single Lane Parallel-Type Entrance Ramp Terminal Using Vehicle Dynamics Model for Freeways
Authors: Saremi Niousha , Kordani Ali Abdi , Zarei Mohammad , Kohansal Akram
Published: April 2023

Providing an appropriate length of highway entrance ramps is an important feature that should be considered in freeway design. The recommended minimum acceleration lane length in the Green Book of the American Association of State Highway and Transportation Officials (AASHTO) is currently used for designing entrance ramp terminals. However, in some cases, traffic congestion and crashes are observed when heavy trucks enter freeways, which indicates they could not accelerate enough and did not reach the merge speed at the end of the acceleration lane. Therefore, several scenarios were simulated using a dynamic simulation model (TruckSim) for heavy vehicles with weight to power ratios of 61, 67, 86, and 108 (kg/kW) and grades of zero, ±3, and ±5%. Subsequently, a linear regression model was presented to calculate acceleration lane lengths. The results showed that the acceleration rate of heavy vehicles is not adequate, especially in upgrades. For example, at +5% upgrades, heavy trucks cannot accelerate to the merge speed mentioned in the AASHTO. Conversely, the acceleration rate of heavy vehicles increased in downgrades; therefore, some heavy vehicles were able to achieve merge speed along the proposed length of AASHTO.

Youth of the ukrainian provinces of the Russian Empire in the ­revolution of 1905
Authors: Kryvobok Oleksandr
Published: April 2023

Youth participation in the revolutionary events of 1905-1907 began long before the beginning of the revolution. Opposition sentiments towards the regime ruling in the Russian Empire have been forming since the second half of the 19th century. Their activation coincides with the growth of the higher education system and organized illegal student life at the end of the 19th and the beginning of the 20th centuries. The presented article analyzes the main factors and forms of involvement of student youth in opposition academic, and later - political activities. The conclusion is substantiated that even during the revolutionary events of 1905-1907 there is no reason to speak of a consolidated political position of student youth as such. In the youth environment, there were various groups, and most of them were not inclined to political speeches under the conditions of meeting the basic requirements of academic freedom.

Published: April 2023

The analysis of the spatial interrelationship between soil properties and slope aspect is vital for understanding the range of influence on soil depth, moisture, and stone content distribution. This study aimed to investigate the spatial interrelationship of topsoil moisture and stone content in different slope aspects and soil depth. The 53.7 km2 watershed was divided into a 500m by 500m grid using ArcGIS and 230 soil samples were collected. In each sampling point, the soil was taken at three soil depth classes (0–25cm, 25–60cm, and 60–100cm) using a cylindrical auger, then soil samples were tested to determine the percentage of topsoil moisture, and stone content. The spatial interrelationship between aspect, soil depth, topsoil moisture, and stone content was analyzed using the R and GS+ software. The study had shown non-significant effects of aspect on topsoil moisture, stone content, and soil depth. However, topsoil moisture tends to be higher on the north-facing slope, while stone content tends to be higher on the southeast-facing slope. The analysis of Local Moran’s I revealed that topsoil moisture, stone content, and soil depth were significantly autocorrelated. The cross-semivariogram analysis of soil depth with topsoil stone content depicted a negative spatial correlation. The experimental cross-semivariogram of soil depth versus topsoil moisture was positively fitted to the exponential function, whereas soil depth with topsoil stone content was best fitted to the Gaussian model. Overall, soil depth is the more influential factor than the slope aspect regarding topsoil moisture depletion and stone content distribution in the study watershed.

Published: April 2023

At Banganga, Kapilbastu, Nepal, a field experiment was conducted in the spring of 2021 to determine the performances of transplanted spring rice under different weed management techniques. With five treatments and four replications, the experiment was structured as a single-factorial Randomized Complete Block Design (RCBD). The treatments consisted of Pretilachlor 50% EC (dose: 500 ml a.i. per acre) as pre-emergence herbicide, Pretilachlor 50% EC (dose: 500 ml a.i. per acre) as pre-emergence herbicide plus hand weeding at 20, 40 DAT, Hand weeding at 20 DAT, 40 DAT, 60 DAT, Cono-weeding at 20 DAT, 40 DAT, 60 DAT and control. The plots treated with Pretilachlor plus hand weeding recorded a significantly higher plant height (99cm), higher number of effective tillers per meter square (11.97), higher panicle length (26cm), and higher number of grains per panicle (200.60) at 90 DAT. The sterility percentage and the no. of grains per panicle were not affected by the weed management practices. Cono-weeding was found statistically superior in terms of grain yield (6.09 Mt ha-1) and harvest index (42.10 %). The experiment concluded that the weed management practices affect the grain yield of transplanted spring rice.

Published: April 2023

The aim of this study was to assess the nutrient composition and sensory properties of breakfast cereal made from yellow maize and enriched with soybean and groundnut flours. Yellow maize was replaced with groundnut (GF) (15–35%) and soybean flour (SBF) (10–15%) to produce a more nutritionally balanced breakfast cereal. Proximate, mineral, vitamin, and sensory analysis were carried out on the formulated breakfast cereals. The results showed that groundnut and soybean flour supplementation significantly increased the protein content (20.90–23.01%) as compared to the control along with an increase in fat (10.52-11.28%), crude fibre (2.98–3.90%), and ash (1.99–2.60%), while carbohydrate (57.09–52.66%) and energy (406.64–403.79 Kcal) decreased with the incremental addition of SBF and GF. Similarly, calcium (36.16-37.98 mg/100g), magnesium (32.16-37.98 mg/100g), potassium (10.62-12.16 mg/100g), iron (42.21-48.65 mg/100g) and vitamin A (70.07-74.01) g/dl) content of the breakfast cereals also increased significantly with increasing SBF and GF substitution, while a decrease was observed for phosphorus. The highest total score of sensory evaluation was for the control sample (golden morn), which was followed closely by the sample containing 20% GF and 15% SBF. Higher levels of SBF and GF can improve the nutritional value of breakfast cereals.

Published: April 2023

Farmers in Bangladesh are enthusiastic in dragon fruit farming as a new and promising crop that offers both difficulties and potential. The purpose of the study was to examine the advantages and disadvantages of this novel fruit from the perspective of growers. It is a descriptive survey research which was conducted in purposively selected four Upazilas of Chapainawabganj region of Bangladesh including Chapainawabganj Sadar, Gomastapur, Nachol, and Godagari from 16th April to 25th May, 2022. Pearson’s correlation test was administered to determine the relationship between socio-demographic characteristics of the growers and their knowledge on dragon fruit production. Socio-demographic profile of the randomly selected growers of the study revealed that majority of the respondents were in their middle age, highly educated, had a medium annual income with medium sized land, little farming experience, less training and higher cosmopolitan behavior. Majority of the dragon fruit growers showed high level of understanding regarding dragon fruit cultivation and their fellow farmers and mass media were determined to be the most effective sources of information. According to the study’s findings, the majority of farmers were inspired to grow dragon fruit because it is more resistant to pests and diseases, promotes excellent health, yields for a long time, and can be grown from both seeds and cuttings. Furthermore, the fruit has a higher profit margin than other field crops. Weeds, bird invasions, high labor expenses, lack of technical knowledge of farmers on dragon fruit farming were recognized as major obstacles to fruit production. According to a correlation analysis, farmers’ age, extension contacts, and cosmopolitan nature were significantly and positively correlated with their knowledge of growing dragon fruit. More government support, especially from the Department of Agricultural Extension (DAE), and fixing the issues described above could increase the fruit’s future prospects in the country.

Published: April 2023

Perdebatan tentang perbedaan agama seolah telah menjadi permasalahan yang mengakar, akarnya telah jauh masuk ke dalam tanah sehingga sangat sulit untuk dicabut. Perdebatan keagamaan seolah tidak menemukan titik temu dan justru semakin memanas akibat kemunculan penghakiman terhadap keyakinan atau agama yang berbeda, kondisi ini seolah memposisikan keyakinan satu adalah yang benar sedangkan keyakinan lain adalah sesuatu yang salah. Dengan kondisi ini diperlukan kesadaran beragam dengan sikap moderat sesuai dengan wacana yang cukup sering disampaikan belakangan ini. Sebagai bagian dari keyakinan yang diakui di Indonesia, Hindu sesungguhnya telah memiliki berbagai konsep dalam upaya hidup harmonis di tengah perbedaan yang ada. Berbagai konsep yang dimiliki Hindu tidak hanya sebuah wacana untuk hidup moderat, damai dan harmonis, namun konsep ini mengajarkan umat Hindu untuk dapat menumbuhkan puncak kesadaran berketuhanan dengan menyadari bahwa semua makhluk yang ada adalah manifestasi dari Tuhan. Sehingga tidak ada satu alasanpun bagi umat Hindu untuk menghamiki orang lain apalagi merasa benar dan selalu menyalahkan agama orang lain

Kata Kunci: Hindu, Moderasi, Kesadaran Berketuhanan

Published: April 2023

El objetivo de esta investigación fue comprender los significados que construyen niños y niñas con diagnóstico oncológico acerca de la muerte y la influencia de dichos significados durante el duelo anticipatorio en cuidados paliativos. El estudio se orientó sobre cuatro ejes conceptuales: 1. la perspectiva de construcción de significados, 2. la articulación entre pensamientos, sentimientos y creencias, 3. las consideraciones sobre la representación de la muerte y, 4. las reflexiones sobre la muerte y los niños. Fue una investigación descriptiva e interpretativa con un diseño cualitativo desde el que se apostó por la comprensión de significados a través de técnicas interactivas y talleres reflexivos. Entre los resultados se destaca que la muerte es una experiencia desconocida de difícil representación y un tabú en sociedades occidentales, lo cual se expresa en complejas disposiciones afectivas. Se destaca una tendencia a minimizar lo real y definitivo de la muerte a través de creencias que apelan a la continuidad del self por medio de una identidad espiritual o simbólica, y una incidencia significativa del pensar y sentir del adulto en la configuración del mundo interno del niño/a. La muerte en la infancia es un tema profundamente doloroso e inesperado que demanda a las familias, equipos de salud y a la sociedad en general un abordaje complejo. El acompañamiento psicosocial en cuidados paliativos pediátricos invita a Trabajo Social a disponer recursos para contribuir a la calidad de vida a través de una práctica profesional fundamentada teórico-metodológicamente y en permanente reflexión.

Introduction of Level Sensor Assembly in Korea Space Launch Vehicles II
Authors: Kim Juwan , Jeon Sang-Woon , Cho Kiejoo , Sik Cho Gyu
Published: April 2023

Level sensors are widely used in the aerospace field to measure the quantity of propellant. Especially, measuring the quantity of the propellant is very important in launch vehicles because the performance of launch vehicles strongly depends on the weight of the propellant. Many launch vehicles use cryogenic propellants, such as oxygen, hydrogen, and methane, and level sensors for cryogenic propellants are needed in these applications. In this study, the development process for the newly designed level sensor assembly based on a magnetostrictive level transmitter is introduced. Based on the thermal analysis, a level sensor assembly using a magnetostrictive level transmitter for cryogenic propellants was proposed. Several experimental studies have been conducted for the assembly level and the complete integrated system level to confirm the performance of the level sensor assembly. Finally, this newly designed level sensor assembly is successfully validated by flight tests of Test Launch Vehicle and Korea Space Launch Vehicle II.
Design and Optimization of a Hinged Mechanism Guiding Flap to Three Positions
Authors: Dai Jiahua , Liu Peiqing , Chen Yacan , Wen Xueliang , Li Ling , Dong Meng
Published: April 2023

The design of high-lift devices for commercial aircraft is a multidisciplinary problem. One of the difficulties is that the mechanism is difficult to accurately guide the flap to the aerodynamic design position. Therefore, the traditional high-lift device often adopts a complex mechanism, which brings the disadvantages of high structure weight and low reliability. The hinge flap composed of pure rods improves these disadvantages with a small loss of aerodynamic performance. In this paper, a new type of hinge flap mechanism that can meet the needs of three-position design is studied. First, the calculation method of the mechanism parameters and the kinematics simulation are introduced. The guiding position of the mechanism is basically consistent with the aerodynamic design position, and the maximum error is less than 0.1 mm. Then, the mechanism parameters are optimized, including two aspects. The fairing size and the tangential load of the mechanism are optimized for the support part, and the inboard and outboard rotary actuators are optimized to maintain a linear relationship as much as possible with a maximum deviation of no more than 0.058 deg. Finally, the aerodynamic performance of the takeoff and landing configurations guided by the mechanism is evaluated.
Certification-Constrained Vertical Tail Sizing and Power Split Optimization for Distributed Electric Propulsion Aircraft
Authors: Xie Jiacheng , Cai Yu , Sarojini Darshan , Harrison Evan D. , Mavris Dimitri N.
Published: April 2023

Distributed electric propulsion (DEP) concepts leverage the synergistic benefits of aeropropulsive coupling and improve the overall flight efficiency by placing propulsors at optimal locations, such as the wingtip. However, placing propulsors far away from the aircraft centerline may bring aircraft difficulties in complying with critical-engine-inoperative flight certification rules. To investigate the impact of certification requirements on the DEP aircraft design, this paper takes NASA’s PEGASUS concept as a use case and presents a study of certification-constrained vertical tail sizing and propulsive power split optimization. For comparison, a vertical tail retrofit study is also conducted on the ATR 42-500 aircraft using the same design space, to gain insights into the different impacts of certification constraints on the design process between conventional and unconventional aircraft. In each study, a design space exploration is performed, including a feasibility test and a multi-objective optimization. The feasibility test shows that the certification constraints yield a much smaller feasible design space for the DEP concept when compared to the conventional aircraft. Despite a much smaller feasible design space, the constrained Pareto optima of the PEGASUS still exhibit lower cruise drag coefficient, fuel burn, and operational energy cost when compared to those of the ATR 42.
Numerical Investigation into Single and Double Gurney Flaps for Improving Airfoil Performance
Authors: Genest Benoît , Dumas Guy
Published: April 2023

The impact of single and double Gurney flaps of heights within the range of [Formula: see text] is determined for a typical symmetrical airfoil (NACA 0015) by numerical simulations using an unsteady Reynolds-averaged Navier–Stokes approach. The optimal scaling of the Gurney flap to maximize the lift-to-drag ratio of the airfoil is revisited and confirmed to depend on the boundary-layer thickness in the region where it is deployed. Appropriate scaling rules for both single and double Gurney flap are proposed. Studying the Gurney flap’s pressure distribution at a finely resolved level highlights its effect on the overall foil’s pressure distribution. Finally, the unsteady simulations carried out are harnessed to determine the shedding frequencies generated by the flaps and the flow structures associated with them, hinting at the physical mechanisms by which Gurney flaps may increase lift at a low drag cost, thus improving the lift-to-drag ratio of the airfoil.

Published: April 2023

Пекинская опера, как часть традиционной культуры КНР, имеет тысячелетнюю историю с момента своего развития. За этот период истории Пекинская опера стала важной формой художественного выражения в повседневной жизни населения Китая благодаря непрерывному развитию. Еще несколько десятилетий назад Министерство образования КНР признало важность наследования пекинской оперы. С развитием качественного образования содержание преподавания Пекинской оперы в музыкальных классах начальной школы Китая постепенно становится богаче, но в настоящее время влияние популярной музыки и зарубежной музыкальной культуры также вызвало дилемму в направлении развития пекинской оперы. Статья посвящена исследованию вопроса о важности сохранения наследия китайской традиционной оперы в музыкальном образовании КНР, сложностям использования китайской оперы на занятиях музыки в учебных заведениях Китая и способам их преодоления. Стоит выбрать несколько студентов, которые очень хотели попробовать, но не осмелились участвовать в конкурсе. После того, как несколько студентов возглавят демонстрацию, другие студенты, которые были заинтересованы, также могут присоединиться к конкурсу пекинской оперы. В конечном итоге у большинства учащихся может проснуться живой интерес к изучению музыкальной культуры родной страны.

Peking Opera, as part of the traditional culture of the PRC, has a thousand-year history since its development. During this period of history, Peking Opera has become an important form of artistic expression in the daily life of the Chinese people through continuous development. A few decades ago, the Chinese Ministry of Education recognized the importance of inheriting Peking Opera. With the development of quality education, the teaching content of Peking opera in China's elementary school music classes is gradually becoming richer, but at present, the influence of popular music and foreign musical culture has also caused a dilemma in the development direction of Peking opera. The article is devoted to the study of the importance of preserving the heritage of Chinese traditional opera in the musical education of the PRC, the difficulties of using Chinese opera in music classes in Chinese educational institutions and ways to overcome them. It is worth choosing a few students who really wanted to try, but did not dare to participate in the competition. After a few students lead the demonstration, other students who were interested can also join the Peking Opera Competition. Ultimately, most students may awaken a keen interest in studying the musical culture of their native country.

В данном исследовании рассмотрены актуальные аспекты реализации дифференцированного обучения высшей математике в непрофильном высшем учебном заведении. Реализована технология обучения дисциплине «Математический анализ» для студентов, обучающихся по программе высшего образования — программе бакалавриата по направлению подготовки 38.03.01 Экономика. При проектировании и дифференциации курса в рамках компетентностного подхода для разноуровневых групп студентов, моделировании и анализе возникающих при этом образовательных феноменов применен математический аппарат теории графов. В рамках проведенного психолого - педагогического эксперимента реализовано два подхода по внедрению дифференцированного обучения для разноуровневых по уровню начальной предметной подготовки групп студентов, основанных на возможностях электронного обучения с применением системы дистанционного обучения Moodle. Эксперимент показал возможность эффективного внедрения разной степени дифференциации в зависимости от степени разноуровневости групп студентов. Статистически значимые результаты проведенного эксперимента показывают более высокое качество образования в экспериментальных группах, чем в традиционной модели обучения. Данное исследование актуально в рамках внедрения электронного обучения и дистанционных технологий на уровне высшего образования РФ.

In this study, the actual aspects of the implementation of differentiated teaching of higher mathematics in a non-core higher education institution are considered. The technology of teaching the discipline "Mathematical analysis" has been implemented for students studying under the higher education program — bachelor's degree program in the field of preparation 38.03.01 Economics. When designing and differentiating the course within the competence approach for multi-level groups of students, modeling and analyzing the educational phenomena that arise in this case, the mathematical apparatus of graph theory is used. Within the framework of the conducted psychological and pedagogical experiment, two approaches were implemented to introduce differentiated learning for groups of students with different levels of initial subject training, based on the possibilities of e-learning using the Moodle distance learning system. The experiment showed the possibility of effective implementation of different degrees of differentiation depending on the degree of multilevel groups of students. Statistically significant results of the experiment show a higher quality of education in experimental groups than in the traditional learning model. This study is relevant in the framework of the introduction of elearning and distance learning technologies at the level of higher education in the Russian Federation.

Применение интерактивных методов обучения оказывает положительное влияние на развитие навыков говорения на иностранном языке, в частности на английском. Авторы описали современные формы, принципы и методы организации интерактивного обучения коммуникативным навыкам на английском языке студентов-медиков. В данной статье дано рассмотрены основные методики интерактивного обучения навыкам говорения. Авторы определили сильные и слабые, с их точки зрения, стороны в применении интерактивных методов обучения студентов навыкам говорения. Было отмечено, что интерактивные занятия не просто способствуют повышению уровня знаний студентов по английскому языку, но и развивают их способности работать как самостоятельно, так и в команде, с нестандартным подходом к решению задач. Нами были определены оптимальные интерактивные технологии обучения студентов-медиков монологической и диалогической речи через посредство интерактивных технологий: технологии кооперативного обучения, технологии коллективно-группового обучения, дискуссионных технологий и моделирования. Технологии кооперативного обучения, применяемые на занятиях английского языка, подразумевают работу в малых группах, использования метода «Карусель». Данные технологии могут использоваться в учебных группах с разным уровнем знаний английского языка.

The use of interactive teaching methods has a positive impact on the development of speaking skills in a foreign language, in particular in English. The authors described modern forms, principles and methods of organizing interactive teaching of communication skills in English for medical students. This article describes the main methods of interactive teaching of speaking skills. The authors identified the strengths and weaknesses, from their point of view, of the use of interactive methods for teaching students the skills of speaking. It was noted that interactive classes not only contribute to increasing the level of students' knowledge of the English language, but also develop their ability to work both independently and in a team, with a non-standard approach to solving problems. We have identified the optimal interactive technologies for teaching medical students monologue and dialogic speech through interactive technologies: cooperative learning technologies, collective group learning technologies, discussion technologies and modeling. Cooperative learning technologies used in English classes involve working in small groups, using the Carousel method. These technologies can be used in educational groups with different levels of knowledge of the English language.

The article examines the possible prospects for the development of the Russian economy due to the intensification of the processes of digital transformation. The eventuality of Russia’s digital transformation is due to many mutually influencing aspects: the development of Industry 4.0; the processes of redistribution of world domination; the accumulated potential of the Russian Federation and ambitious tasks that need to be solved in an accelerated mode to achieve the national goal of competitiveness and stability of the state. In the presented study a review of scientific publications on the topic of the digital economy and its transformation is made, the article identifies the areas of study of the issue. Along with this, an analysis of the regulatory framework of the Russian Federation in terms of ensuring the processes of digital transformation is made. An important aspect of the study is the analysis of foreign experience of digital transformation, which has both success and certain problems that need to be addressed in medium– and long-term state planning programs. The unconditional parameter of the implementation of the digital transformation of the Russian Federation is the participation in the global confrontation of countries with the target of accelerated technological development, and in the future – the formation of digital superiority to ensure the stability of the state development. The success of the national program «Digital Economy» depends on the targeted order of impact on all objects of the socio–economic systems of the Russian Federation, and in the next five years the Russian state should improve the efficiency of the use of information technologies.
Integration potential of the digital platform in the field of international trade: problems and solutions
Authors: Nuriev B. D.
Published: April 2023

The article considers the digital platform as an integration resource in the field of international trade. The author proves that in order to use the digital platform more effectively, it is necessary to solve a number of key issues. So, at present, a common understanding of the digital platform and other related categories has not been developed in the research and analytical literature. The article emphasizes that the rules of using a digital platform in the field of international trade remain unclear for Russian business, therefore, the lack of legalization of this type of digital innovation affects its low demand in the business circles. The paper emphsizes that in the context of the regionalization of the world economy, a clear and unambiguous understanding of those areas that are priorities in the economic policy pursued by the state is of particular importance for Russian business. The author believes that the era of globalization of the world economy is coming to an end, and it is being replaced by a period of regionalization. In the context of territorial disintegration and increasing competition, the role of the digital platform as a factor that significantly reduces the costs of doing international business will increase. In the course of the research, both general scientific methods of cognition and narrow-profile ones peculiar to such branches of knowledge as the management theory, law and economics were used.
