Published: June 2023

While creating the sustainable construction systems it is crucial to innovate in production of construction materials by maximizing recycling and reuse of the materials during production and use of the buildings. The intention of this paper is to provide new insights and better understanding of sustainable oriented innovation in production of construction materials, in particular substitution of cement in mortar with waste material, fly ash, bearing in mind its huge negative impact on the environment. Previous investigations of possible use of fly ash have proven the possibility of its use for the production of cement for lightweight concrete, bricks, asphalt fillers, however the use of the fly ash in cement screeds was not considered.The aim of this work was to examine at first, justification of substitution of cement in mortar with fly ash due to its newly gained properties as change of density, compressive strength and water absorption. In order to take into account aspect of environmental protection the newly gained mechanical properties of the materials were tested in terms of its convenience for use in cement screeds.

Authors: Guo Qingsuo , Wang Zhiming , Qin Wenshan , Dong Fei
Published: June 2023

The VOF model was employed to simulate the pool boiling under typical engineoperating temperature conditions and was experimentally validated. A trapezoidal raised surface morphology with a hydrophilic-hydrophobic combination was designed, and the heat transfer ability and bubble evolution phenomena on the surface were analyzed. Then the variance contribution of each structural parameter of the trapezoidal raised surface to the average surface temperature rise and the average surface heat transfer was evaluated. Finally, the NSGA-II algorithm was used to optimize the structural design of the designed trapezoidal raised surface with the optimization objectives of minimizing the average temperature rise and maximizing the average heat transfer coefficient. Specifically, compared with the hydrophilic smooth surface, the optimized structure showed an increase in the average heat transfer coefficient by 194.5% and a decrease in the maximum average temperature rise, ?T, by 33.9%.
Impact of coil pitch on heat transfer enhancement of a turbulent flow of α-Al2O3/DW nanofluid through helical coils
Authors: Abdullah Mustafa , Hussein Adnan
Published: June 2023

The current study experimentally examines the impact of coil pitch on heat
transfer behavior and friction factor through helical coils for ?-
Al2O3/Distilled water nanofluid turbulent flow. These tests were conducted
on coils with coil pitches of 20, 35, and 50 mm. The nanoparticle volume
fraction was 0.1%. The nanoparticles in a 0.1% volume concentration of
nanofluid increased the heat transfer rate and friction factor compared to
those of distilled water. Increases in coil pitch also resulted in greater
heat transfer efficiency. A correlation between the Reynolds number, the
Prandtl number, and the curvature ratio of the coil was also shown to be
connected to the Nusselt numbers for the flow of nanofluids within the
coils.

Published: June 2023

Unbalanced drying air and temperature distribution in a dryer is among the major cause of non-uniformity in moisture content of dried food. Thus, the distribution of air and temperature in corner-ended, corner-ended with deflector, curved-ended, and curved-ended with defectors were investigated. Velocities used were 2 m/s, 4 m/s, and 6 m/s while temperatures ranged from 40-60?C. The design with lowest deviations in simulated and actual drying parameters was fabricated to dry mushrooms. Results showed that adding deflectors improved drying air and temperature distribution. The corner-ended with deflector dryer configuration was superior to other designs, with 6 m/s and 60?C being optimal. A mass transfer simulation of the corner-ended with deflectors configuration had moisture evaporate from 1.00-0.11 in 2000 seconds. A comparison of moisture ratios in the two dryers gave R? = 0.9965, which was acceptable. Drying at 55-60?C gave the best Lentinan content and rehydration ratio for mushrooms.

Authors: Spasic Zivan , Begovic Veljko , Milanovic Sasa , Jovanovic Milos
Published: June 2023

The paper presents the aerodynamic performance of an axial reversible fan for high air temperatures, obtained by applying the similarity theory and numerical flow simulations. This analysis was performed for the possibility of installing the existing structure of an impeller of a reversible fan in a jet fan for the longitudinal ventilation of a tunnel. The direction of forced flow in tunnels changes, and it is always towards low atmospheric pressure, i.e. in the direction of natural air-flow. These fans often work with high air temperatures in the event of a fire. The paper shows the performance of fans for high operating air temperatures, up to 400?C. The results were obtained through numerical simulations of the flow in an original design fan, whose performance was experimentally determined for normal atmospheric operating conditions (? = 1.2 kg/m3). Performances are given for two fan speeds. Unnecessary corrections of the existing impeller design for use in jet fans for tunnel ventilation were also considered.

Artemis Base Camp and Exploitation of Outer Space: Problems and The Needs of Legal Framework
Authors: Handayani Irawati , Juliana Annisa , Gumelar Garry
Published: June 2023

NASA introduced the Artemis Program in 2017, consisting of several missions, such as establishing a permanent outpost called Artemis Base Camp and exercising commercial and non-commercial exploitation on the Moon. For the program to be carried out properly, the United States established a series of bilateral agreements with other countries, namely the Artemis Accords. One of the functions of the Accords is as the supporting legal instrument for the implementation of the Artemis Program. However, its implementation raised several legal problems related to the legality of establishing Artemis Base Camp and violations of the basic principles of space law related to activities. This paper will specifically discuss the legal issues arising from using the Artemis Accords as one of the supporting legal bases for the two Artemis Program activities, according to space law. This article argues that Artemis Base Camp falls within the definition of a station explained in the Outer Space Treaty and the Moon Agreement. Then, the construction does not violate the principle of non-appropriation in Article II of the Outer Space Treaty because it does not fulfill the three main components of appropriation activities. Although establishing the Artemis Base Camp and exploiting lunar resources for non-commercial purposes is permitted, a basic legal framework still needs to be established to regulate permanent outposts and the exploitation of lunar resource activities. A specific legal framework is needed to avoid multiple interpretations leading to legal uncertainty.
Influence of Texture Effects on the Laser-Irradiated Tool Performance
Authors: Brover G. I. , Shcherbakova E. E.
Published: June 2023

Introduction. Laser surface treatment of mechanical engineering products makes it possible to increase their durability. However, the laser hardening process is not good at the consistency of results, since choosing the irradiation modes and schemes of specific products, texture effects in the zones of laser exposure are not taken into account. This leads to premature wearing and even destructing the working surfaces of irradiated products. Therefore, the work objective is to study the mechanism of influence of the structure of the laser-hardened layer on the operational properties of the tool.

Materials and Methods. The materials for this study were tool steels: R6M5 and R18 (according to the EN 10027 standard tool steels: 1.3355, 1.3343). Pulsed laser irradiation was carried out at the technological device Kvant-16 with a radiation power density of 70–250 MW/m2. Scanning probe and optical microscopy, X-ray diffraction and durometric methods for analyzing the steels structure were used. The values of steel strength in bending and impact strength were determined before and after laser treatment.

Results. It has been experimentally proven that it is necessary to strengthen the sections of the products working surfaces that are subject to maximum wear and are under the action of compressive stresses during operation. It is shown that textural effects in the laser treatment zones lead to a decrease in the friction coefficients and contribute to an increase in the wear and adhesion resistance of the steels surface layers.

Discussion and Conclusion. The results of the research carried out make it possible to rationally select the surface laser processing modes and schemes of products for various functional purposes and ensure their operability with a guarantee. The possibilities increasing the structural strength and properties of the tool due to laser alloying the surface layers of powder-coated steels and stabilizing tempering after laser irradiation are determined.

Published: June 2023

Introduction. Recently, much attention has been paid to the issues of long-term development of specialized fire and rescue units of the Federal Fire Service of the State Fire Service. In this regard, there is a need to develop criteria to justify the use of a particular service as part of specialized fire and rescue units. Therefore, the objective of this study is to develop a mathematical model to justify the need to use radiation and chemical protection services as part of specialized fire and rescue units in the subjects of the Russian Federation.

Materials and Methods. Justification of the need to use radiation and chemical protection services as part of specialized fire and rescue units has been carried out using the theory of fuzzy sets. The mathematical model takes into account the climatic and geographical features of the subjects, indicators of social, technical and economic development, and the risks of emergencies and fires. It also takes into account the availability of forces and means of a Unified State system for the prevention and liquidation of emergency situations in each subject of the Russian Federation. In total, 15 indicators were selected that characterize the need to use radiation and chemical protection services as part of specialized fire and rescue units. A desirability function is defined for each indicator, which shows which values of the indicator are the most acceptable from the point of view of the need to use radiation and chemical protection services as part of specialized fire and rescue units.

Results. Using the developed model, the subjects of the Russian Federation are identified in which the need for radiation and chemical protection service as part of specialized fire and rescue units is the highest. It is proposed to create a radiation and chemical protection service of the 1st category in the Moscow, Sverdlovsk and Rostov regions, in the Krasnoyarsk and Primorsky Territories and in St. Petersburg. In 21 subjects it is proposed to use the radiation and chemical protection service of the 2nd category. In other subjects, it is proposed to assign the 3rd category to the radiation and chemical protection service.

Discussion and Conclusion. The mathematical model developed using the theory of fuzzy sets will allow a more differentiated approach to the creation of a radiation and chemical protection service as part of specialized fire and rescue units and increase the efficiency of the functioning of this service and specialized fire and rescue units as a whole. The presented model can be applied to justify the need to use other services and groups as part of specialized fire and rescue units.

La subjetivación en el último Foucault
Authors: Ortiz Juan Emilio
Published: June 2023

El presente escrito se propone reflexionar acerca del proceso de subjetivación en los últimos trabajos de Michel Foucault. Siguiendo sus precisiones de método, se buscará reconocer el nudo constituido por los dispositivos de poder y las técnicas de sí. La idea será mostrar la imbricación efectiva de nuestra subjetividad en procesos más generales de dominación. Es sabido que el gran acierto del neoliberalismo radica en articular nuestros placeres, prácticas y saberes más arraigados con formas abusivas de ejercicio del poder que unos ejercen sobre otros.

Ante esta situación, confío en que el método ofrecido por Foucault puede contribuir a descentrar esta posición subjetiva funcional a los sistemas de dominación y, al mismo tiempo, fortalecer un proceso de subjetivación pulido, razonado y realista capaz de evitar que la subjetividad se convierta en el cebo utilizado por diversas estrategias de dominio.
H
∞ interpolation constrained by Beurling–Sobolev norms
Authors: Baranov Anton , Zarouf Rachid
Published: June 2023

We consider a Nevanlinna–Pick interpolation problem on finite sequences of the unit disc, constrained by Beurling–Sobolev norms. We find sharp asymptotics of the corresponding interpolation quantities, thereby improving the known estimates. On our way we obtain a S. M. Nikolskii type inequality for rational functions whose poles lie outside of the unit disc. It shows that the embedding of the Hardy space H
2 into the Wiener algebra of absolutely convergent Fourier/Taylor series is invertible on the subset of rational functions of a given degree, whose poles remain at a given distance from the unit circle.

Film memiliki dua unsur yang dapat mempengaruhi jalan cerita yaitu unsur naratif dan unsur sinematik. Mise En Scene merupakan salah satu elemen dari unsur sinematik pada film, Mise En Scene merupakan segala hal yang terdapat pada pandangan di depan kamera. Tujuan dari analisis ini adalah untuk mengetahui Mise En Scene dalam film pendek berjudul Tilik 2018. Dalam menganalisis film, Mise En Scene sendiri memfokuskan diri pada sesuatu yang ada di depan kamera seperti desain set atau latar, pencahayaan, akting serta pergerakan para aktor. Tilik merupakan salah satu film pendek yang dapat dibahas mengenai 1) bagaimana setting latar yang terdapat pada cerita, 2) bagaimana kostum serta tata rias yang digunakan apakah membuat karakter yang sesuai dengan pemain atau tidak, 3) akting para pemain sudahkan sesuai dengan apa yang diharapkan atau tidak. Hasil akhirnya memfokuskan pada actor Bu Tejo yang sangat mendominasi karakternya. Bu Tejo yang membuat film pendek TILIK ini dapat terkenal karena akting yang bagus dapat membuat para penonton kesal dengan hasil karakternya. Film Tilik merupakan film pendek yang terkemas dengan unik karena cara pengambilan gambar yang hanya begitu saja, namun banyak arti dari setiap scene yang akan dibahas menggunakan elemen Mise En Scene.   Kata Kunci: Mise En Scene, film Tilik, Sinematik Abstract: The film has two elements that can influence the storyline, namely narrative elements and cinematic elements. Mise En Scene is one of the elements of the cinematic element in the film, Mise En Scene is everything that is visible in front of the camera. In analyzing the film, Mise En Scene itself focuses on something that is in front of the camera such as set or background design, lighting, acting and the movements of the actors. Tilik is one of the short films that can be watched to discuss about 1) what is the background setting in the story, 2) how are the costumes and make-up used to make the characters suit the players or not, 3) the acting of the players is in accordance with what is expected or not.

Indo-Russian Economic Engagement: Legacy Issues, Dynamic Shifts, and Possibilities for the Future
Authors: Mukhopadhyay Abhijit
Published: June 2023

The economic relationship between India and Russia has been limited and faced various challenges historically. However, changing geopolitical and geoeconomic situations have created new opportunities while also presenting challenges and risks. This paper aims to analyse the legacy issues and dynamic shifts in international trade and order that are currently taking place. The article explores the ongoing transformation of Indo-Russian economic engagement and proposes possible means for moving forward. The existing advantages of both countries in the areas of trade and investment are also outlined.

Assuming a resolution to the Russian Special Military Operation in Ukraine, the paper proposes an economic roadmap for continuing the recent momentum in the trade and economic relationship between Russia and India. The first step is to strengthen bilateral trade in existing priority export sectors of both countries. This can be followed by deeper cooperation in oil, civilian nuclear energy, and defence sectors. The introduction of rupee-rouble trade, even partially, could significantly boost these efforts. The paper also advocates for involving the private sector in these efforts by adopting a proactive approach by both governments.

By combining immediate efforts with long-term geopolitical maneuvers on both sides and an early resolution of the Russian Special Military Operation in Ukraine, it is possible to push bilateral trade and investment levels onto a sustainable growth path in the future. The paper argues strongly for this approach.
Russia-India Economic Cooperation: Current Trends and Promising Directions
Authors: Kulik Lydia
Published: June 2023

The prevailing geopolitical conditions, characterized by Russia's reorientation away from the West and India's steadfast pursuit of an independent foreign and economic policy, present a distinctive prospect for Russia and India to enhance their trade and investment collaboration to a heightened level. Despite the existence of a Special and Privileged Strategic Partnership between the two nations, the volume of bilateral trade and mutual investments has long remained insufficient in comparison to their political ties. Nevertheless, the trade volume between Russia and India is now experiencing rapid growth due to the significant increase in exports of energy, fertilizers, iron and steel, wood products, vegetable and animal oils from Russia to India. This article not only examines this phenomenon but also assesses the necessary conditions to address India's escalating trade deficit with Russia. These prerequisites encompass the expansion of the manufacturing sector in India, the rise in purchasing power of the Indian middle class, and the accelerated development of digitization in both India and Russia. The Indian economy has been notably stimulated by key governmental initiatives led by Narendra Modi, such as "Atmanirbhar Bharat" (or "Self-Reliant India"), "Make in India," "Skill India," and "Startup India," all of which prioritize digital transformation. Russian entrepreneurs demonstrate a keen interest in India's market trends and swiftly adapt to India's evolving demands and capabilities. Similarly, Indian business circles exhibit a growing inclination to acquire knowledge about contemporary Russia. This realignment presents an opportunity to expand trade beyond conventional goods and establish new investment connections between the two countries.

Nyeri merupakan rasa tidak nyaman yang umumnya merupakan tanda adanya gangguan fungsi organ atau kerusakan pada organ tubuh seperti peradangan, infeksi kuman, atau kejang otot. Analgesik sintetik merupakan terapi yang paling umum digunakan untuk meredakan nyeri. Namun, penggunaan analgesik menyebabkan berbagai efek samping salah satunya kerusakan gastrointestinal. Bali, dengan keunikan budayanya, memiliki cara pengobatan nyeri secara tradisional yang bersumber dari Usada Tiwang. Penelitian ini bertujuan untuk meninjau efektivitas dan mekanisme pengobatan nyeri secara tradisional menggunakan tanaman herbal berupa rimpang kunyit (Curcuma longa.) dan daun sirih (Piper betle.) yang tertulis dalam Usada Tiwang sehingga dapat dimanfaatkan sebagai pengobatan nyeri alternatif. Metode yang digunakan dalam ulasan artikel ini yakni studi literatur dengan kata kunci analgesik, usada tiwang, Curcuma longa, dan Piper betle dari berbagai penelitian terbaru pada jurnal nasional dan internasional yang telah diterbitkan. Berbagai penelitian melaporkan rimpang kunyit (Curcuma longa.) mengandung senyawa kurkumin yang terbukti mampu mengurangi nyeri dengan mekanisme penghambatan metabolisme asam arakidonat. Sedangkan daun sirih (Piper betle.) mengandung senyawa hidroksikavikol yang dapat menekan produksi siklooksigenase dan mengandung senyawa saponin yang dapat menghambat sintesis prostaglandin sehingga mampu memberikan efek anagesik. Dari studi pustaka ini, dapat disimpulkan bahwa terdapat kesesuaian efek farmakologis dengan efek empiris yang terdapat dalam Usada Tiwang serta telah diketahui mekanisme aktivitas rimpang kunyit (Curcuma longa.) dan daun sirih (Piper betle.) sebagai analgesik sehingga nantinya dapat dijadikan sebagai produk pengobatan alternatif untuk meredakan nyeri.

Sediaan krim adalah salah satu sediaan farmasi yang memiliki tekstur setengah padat yang dialamnya mengandung bahan obat yang terdispersi serta terlarut pada bahan pelarut yang sesuai. Paparan sinar UV pada kulit mampu menyebabkan hiperpigmentasi, dehidrasi, peradangan, kerusakan kolagen, munculnya garis-garis halus, bitnik-bintik coklat dan kerutan yang mampu memicu timbulnya tanda-tanda penuaan dini. Berdasarkan permasalahan tersebut, maka diperlukan senyawa antioksidan yang mampu mencegah efek negatif yang ditimbulkan radikal bebas pada kulit. Literatur review ini dilakukan dengan tujuan untuk merangkum serta memberikan informasi kepada pembaca mengenai potensi bahan alami dari berbagai tanaman yang memiliki aktivitas antioksidan dalam sediaan formula krim. Metode yang digunakan dalam penelitian literature review article berupa pencarian data base melalui Google Scholar (2017-2022). Berdasarkan hasil pencarian melalui Google Scholar didapatkan 30 buah jurnal, dengan lebih dari 30 tanaman yang mempunyai aktivitas antioksidan dengan membandingkan nilai IC50 yang diperoleh. Dari berbagai jenis tanaman pada berbagai formulasi sediaan krim yang mempunyai aktivitas antioksidan yang tergolong sangat kuat (memiliki nilai IC50 < 50 ppm) pada sediaan krim yaitu daun belimbing wuluh (Averrhoa bilimbi L.) yang mempunyai nilai IC50 sebesar 0,118 ppm dengan konsentrasi ekstrak daun belimbing wuluh yang digunakan pada sediaan krim sebesar 7%.

Paparan sinar UV berlebih pada kulit menyebabkan kerusakan foto-oksidatif melalui penghasilan reactive oxygen species dalam bentuk oksigen singlet, radikal superoksida dan radikal peroksida yang memicu sunburn, penuaan dini, fotodermatosis, psoriasis, dermatitis atopik, penurunan produksi kolagen dan kanker kulit. Sehingga diperlukan senyawa yang memiliki aktivitas antioksidan untuk melindungi kulit dari stress oksidatif. Green coffee beans atau kopi hijau merupakan biji kopi yang tidak mengalami proses pemanasan. Green coffee beans mengandung asam klorogenat dan asam kafeat yang memiliki aktivitas antioksidan yang tinggi. Antioksidan merupakan senyawa yang mudah teroksidasi, sehingga diperlukan inovasi dalam penghantarannya sebagai sediaan topikal. Nanoantioksidan menjadi salah satu pendekatan yang dilakukan untuk meningkatkan stabilitas dan pengiriman senyawa antioksidan secara topikal. Tujuan artikel ini untuk mengetahui potensi niosom sebagai sistem pembawa zat aktif green coffee beans dalam bentuk serum wajah. Metode yang digunakan untuk menyusun artikel ini adalah literature review. Hasil yang diperoleh yaitu ekstrak green coffee beans memiliki efek penghambatan yang tinggi terhadap radikal bebas bila dibandingkan dengan coffee roasting. Hal tersebut dikarenakan asam klorogenat mengalami degradasi selama proses pemanasan. Sistem pembawa niosom mampu menjaga stablitas dan meningkatan aktivitas antioksidan dari senyawa fenolik seperti asam klorogenat dan asam kafeat. Sehingga sistem pembawa niosom yang mengandung ekstrak green coffee beans berpotensi sebagai serum wajah antioksidan.

Photoaging adalah penuaan pada kulit yang disebabkan oleh paparan sinar ultraviolet. Indonesia merupakan negara tropis yang mendapatkan paparan sinar matahari sepanjang tahun. Kondisi tersebut mengakibatkan masyarakatnya rentan untuk mengalami photoaging. Degradasi kulit disebabkan oleh protein MMP-1 (matrix metalloproteinase-1), sehingga untuk mengatasi photoaging diperlukan agen penghambat MMP-1. Salah satu penghambat MMP-1 yang digunakan secara luas di masyarakat adalah vitamin C. Rimpang lengkuas diketahui sebagai bahan alami yang memiliki aktivitas antioksidan dengan galangin sebagai biomarkernya. Galangin telah dilaporkan secara in vitro dan in vivo mampu meningkatkan ekspresi faktor pertumbuhan fibroblast dan prokolagen. Penelitian ini bertujuan untuk mendukung pembuktian potensi senyawa galangin sebagai anti-photoaging melalui molecular docking terhadap MMP-1dengan vitamin C sebagai kontrol positif. Tahapan yang dilakukan yaitu preparasi dan optimasi senyawa uji menggunakan Hyperchem 8, dan preparasi protein menggunakan Chimera 1.11.1. Validasi dan docking dilakukan menggunakan aplikasi AutoDockTools 1.5.6 dengan program Autodock4 dan Autogrid4. Metode molecular docking yang dilakukan dinyatakan telah valid apabila nilai RMSD yang diperoleh kurang dari 2 Å. Hasil pengujian molecular docking menunjukkan galangin memiliki afinitas terhadap MMP-1 dengan nilai energi ikatan yang negatif yakni -7,92 kkal/mol. Nilai tersebut lebih negatif jika dibandingkan dengan kontrol positif agen anti-photoaging yaitu vitamin C yang memiliki energi ikatan -5,47 kkal/mol terhadap MMP-1. Model interaksi yang dapat divisualisasikan dari ikatan galangin dengan protein target adalah ikatan hidrogen. Berdasarkan hasil docking, diketahui bahwa galangin memiliki potensi sebagai anti-photoaging dengan mekanisme penghambatan MMP-1 dan dapat dianjurkan untuk dikembangkan.
