Combating plastic pollution in international law: lex lata and lex ferenda
Authors: Solntsev A. M.
Published: February 2024

INTRODUCTION. Global plastic production has increased from 1.5 million tons in 1950 to 390 million tons in 2021, of which only 9 % was recycled, 19 % was incinerated, almost 50 % was disposed of in landﬁlls and 22 % was dumped in landﬁlls, where this waste could be openly burned or released back into the environment. Plastics have changed the global economy and the lives of billions of people for the better. However, their use comes with signiﬁcant environmental and social costs. Plastic waste negatively aﬀects human health and the environment. The life cycle of plastics covers the entire spectrum of activities, from raw material extraction, production, distribution, use, to disposal as waste, and environmental problems can arise at any stage of the plastic life cycle. Most plastic degrades very slowly in the environment. There are currently a number of international commitments to reduce marine litter and plastic waste, particularly from land-based sources, and several applicable international agreements and soﬅ law instruments related to trade in plastics or reducing impacts on marine life. However, none of the international documents provides a global, mandatory, speciﬁc and measurable target to reduce plastic pollution. In this regard, many states, as well as commercial actors and civil society, are calling for the adoption of a global instrument to regulate marine pollution from litter and plastics. In this article, signiﬁcant attention is paid to the analysis of a future treaty aimed at combating plastic pollution.

MATERIALS AND METHODS. This study is based on the analysis of a large volume of materials, including international legal acts, advisory acts, as well as modern doctrinal studies by Russian and foreign authors. The methodological basis of the study was general scientiﬁc (method of logical and system analysis, dialectical method, methods of deduction and induction) and special scientiﬁc (historical-legal, comparative-legal, formal legal methods, method of legal modeling and forecasting) methods of cognition.

RESEARCH RESULTS. In the course of the study, various international acts of a mandatory and recommendatory nature were analyzed, the doctrinal positions set out in the scientiﬁc literature, put forward by domestic and foreign legal scholars, were summarized, and the main problems of combating plastic pollution were identiﬁed.

DISCUSSION AND CONCLUSIONS. Within the framework of this article, an attempt has been made to give answers to the following questions: to what extent the problem of plastic pollution is an important challenge for modern international law, whether current international law eﬀectively regulates the problem of plastic pollution, what should be the content of a new treaty on plastic and what are the positions of states on its content.

Layanan media sosial merupakan salah satu contoh perkembangan teknologi di bidang informasi. Salah satu cara meningkatkan sistem keamanan yaitu digunakannya ilmu kriptografi. Sudah banyak penelitian yang menghasilkan algoritma kriptografi, mulai dari algoritma yang baru, modifikasi algoritma bahkan kombinasi dari beberapa algoritma. Berdasarkan kebiasaan algoritma tersebut hacker tentu akan mencari celah untuk melakukan dekripsi dengan cara mencari algoritma dasar dari proses enkripsi untuk kemudian melakukan hack. Untuk mengantisipasi hal tersebut peneliti ingin melakukan modifikasi bukan pada algoritma pembentuknya melainkan modifikasi dari konversi system bilangan basis 2 berdasarkan Seven Segment Display. Salah satu metode yang sering digunakan untuk proses enkripsi yaitu metode Electronic Code Book (ECB). Seven Segment Display merupakan sebuah tampilan yang terbentuk dari tujuh kelompok segmen LED (Light Emitting Diode) yang dirangkai sedemikian sehingga membentuk angka–angka dari 0 hingga 9. Segmen LED dinotasikan dengan 1 jika menyala dan 0 jika mati, pola tersebut dapat digunakan untuk memanipulasi bit biner 7 bit khususnya karakter angka 0 hingga 9. Modifikasi terletak pada proses pembentukan bit kunci yang dibangkitkan berdasarkan aturan Seven Segment Display. Aturan ini digunakan untuk mengganti nilai bit, bila pada umumnya nilai bit didapat dari sistem bilangan basis 2 maka disini  nilai bit didapat dari aturan seven segment display dan inilah yang merupakan state of the art dari penelitian ini karena belum pernah digunakan sebelumnya.  Hasil penerapannya menunjukkan bahwa data yang dienkripsi menghasilkan chiperteks acak berupa karakter printable pada ASCII dan chiperteks dapat dikembalikan secara utuh tanpa ada informasi yang hilang.

Published: February 2024

Penelitian ini bertujuan untuk mengembangkan alat pendeteksi kualitas minyak goreng kelapa sawit dengan menggunakan metode fuzzy logic Mamdani yang memanfaatkan sensor pH dan sensor cahaya BH1750. Input pada logika fuzzy yaitu nilai pH dan kejernihan minyak yang diukur melalui ADC dari Arduino Mega2560 Pro menggunakan pembacaan data dari sensor BH1750 untuk menentukan tingkat kejernihan pada minyak goreng, sedangkan output berupa kualitas minyak goreng dengan menggunakan desain fuzzy yang dibuat pada software MATLAB. Minyak yang diuji mencakup jenis minyak kemasan premium, kemasan sederhana, dan minyak curah. Pengujian dilakukan pada tiga variasi, yaitu sebelum penggunaan minyak untuk menggoreng telur, setelah satu kali penggorengan telur, dan dua kali penggorengan telur. Hasil penelitian menunjukkan korelasi yang sangat kuat antara kejernihan minyak dengan nilai ADC, mencapai 0,976. Selisih output antara alat dengan perhitungan MATLAB sangat kecil, berkisar antara 0,00 hingga 0,03. Rata-rata diskrepansi pada minyak yang belum digunakan, setelah satu kali penggunaan, dan dua kali penggunaan masing-masing sekitar 0,15%, 0,36%, dan 0,76% berturut-turut. Implementasi logika fuzzy pada alat pendeteksi kualitas minyak goreng berdasarkan pH dan tingkat kejernihan menunjukkan kinerja yang baik dengan akurasi tinggi. Hasil penelitian ini tidak hanya berdampak pada pemantauan kualitas minyak, tetapi juga membuka peluang untuk penerapan logika fuzzy dalam analisis kualitas pada bidang-bidang lain.
Penerjemahan Ungkapan Kenjougo dan Konsep Uchi-Soto pada Takarir Drama Shimbun Kisha
Authors: Dhia Ardhina Salsabila  , Hariri Tatang
Published: February 2024

Penelitian ini bertujuan untuk menganalisis bentuk penerjemahan ungkapan honorifik kenjougo dan konsep uchi-soto dalam takarir drama Shimbun Kisha (The Journalist) tahun 2022. Penelitian ini menggunakan metode deskriptif kualitatif dengan teori honorifik kenjougo yang dikemukakan oleh Iori (2001). Iori mengungkapkan bahwa terdapat tiga bentuk yang termasuk ke dalam honorifik kenjougo yaitu dengan verba tidak khusus (o~suru), verba khusus, dan nomina (prefiks o/go). Sumber data yang digunakan dalam penelitian ini diambil dari data lisan dan tulisan yang terdapat dalam drama Shimbun Kisha episode 1-4 dan diperoleh dari layanan streaming Netflix dengan durasi 45 hingga 60 menit setiap episodenya. Hasil penelitian menunjukkan bahwa bentuk ungkapan kenjougo yang paling banyak muncul dalam drama Shimbun Kisha adalah bentuk verba khusus. Penutur seringkali menggunakan verba khusus kenjougo untuk menonjolkan rasa hormat kepada lawan tuturnya. Berdasarkan hubungan antarpartisipan dan konsep uchi-soto yang terdapat dalam drama Shimbun Kisha, hasil penelitian juga menunjukkan bahwa penggunaan ungkapan kenjougo cenderung digunakan pada konsep soto. Namun, hasil penerjemahan dalam takarir drama Jepang, ditemukan bahwa konsep uchi-soto tersebut seringkali tidak menjadi perhatian penerjemah. Hal tersebut terlihat pada penggunaan beberapa pronomina dalam bahasa Indonesia yang biasanya digunakan dalam situasi nonformal seperti aku, kau, klitik –mu dan klitik –ku. Selain itu, beberapa perubahan makna dalam terjemahan takarir pada ungkapan kenjougo ditemukan. Hal ini disebabkan karena kurangnya pemahaman penerjemah atas konsep uchi-soto. Selain perhatian penerjemah yang minim dengan konsep uchi-soto, perbedaan budaya antara konsep uchi-soto masyarakat Jepang dengan bahasa sopan dalam bahasa Indonesia juga ada. Bahasa Indonesia tidak mengenal ungkapan honorifik kenjougo sehingga terdapat perbedaan persepsi dalam proses penerjemahan. Analisis pada bentuk penerjemahan honorifik tersebut menggambarkan kompleksitas dari proses penerjemahan yang memengaruhi kesepadanan terjemahan.
Kata kunci: kenjougo; konsep uchi-soto; penerjemahan audiovisual.

Computational Evaluation of Turbo- and Electric-Powered Simulators for Turbofan Wind Tunnel Test
Authors: Magrini Andrea , Benini Ernesto
Published: February 2024

Experimental testing of aircraft configurations requires the use of representative engine units to simulate powered-on conditions. For ultra-high-bypass-ratio engines featuring tighter aircraft integration, the installation effects need to be carefully assessed. This paper presents a computational evaluation of two powered simulator models for wind tunnel tests of an ultra-high-bypass-ratio turbofan, based on a traditional air-driven turbo-powered simulator (TPS) and an electric-powered simulator (EPS). Starting from two-dimensional axisymmetric analyses, the design of the baseline turbofan engine and the choice of the duplication parameters of the simulators are described. Several aspects related to the nonreproducibility of the core flow at wind tunnel level are discussed, in terms of mass flow matching, TPS core nozzle pressure ratio, and plug shape of the EPS. The EPS can provide a more faithful reproduction of the flowfield under installation, with an estimated installation drag from 4 to 2 drag counts lower than the reference geometry, compared to the 6 drag counts higher prediction of the TPS.
Optimal Low-Thrust Earth Orbit Transfers with Eclipses Using Indirect Heuristic Approaches
Authors: Pontani Mauro , Corallo Francesco
Published: February 2024

Low-thrust propulsion allows substantial propellant saving if compared to high-thrust systems. However, multirevolution orbit transfers are affected by the unavailability of electrical power along eclipse arcs. This research addresses the identification of minimum-time low-thrust Earth orbit transfers with spacecraft eclipsing. Two different indirect heuristic approaches, based on the use of the analytical conditions for optimality, in conjunction with stochastic fractal search, are applied: 1) regularization through the hyperbolic tangent function and 2) multi-arc formulation of the problem. Both of them require no averaging, and the respective advantages and shortcomings are identified. Approach 2 leads to an extended set of multipoint conditions for optimality, which are shown to be solvable sequentially in the numerical solution process. Implicit costate transformation is proven to be a key ingredient for the purpose of obtaining closed-form solutions of the jump relations that hold for the adjoint variables at light/eclipse transitions. Some illustrative examples prove effectiveness of the two indirect heuristic approaches 1 and 2 in finding minimum-time low-thrust orbit transfers between either two coplanar or two noncoplanar Earth orbits. Approach 2 proves to be superior in terms of both computational efficiency and accuracy of the numerical results.

Authors: Bell John , Redmond Laura , Carpenter Kalind , de la Croix Jean-Pierre
Published: February 2024

Rigid-flex printed circuit board (PCB) robotics have been investigated for exploring planetary terrain currently inaccessible to traditional aluminum body rovers. To push the technology to flight readiness, there must be rigorous methodologies for modeling these structures. This paper presents a modeling methodology for rigid-flex PCB robots subjected to large deformations, failure criteria for each component of the robot (PCB, Nomex hinges, flex cable), validation with drop testing of the rigid-flex PCB robot Pop-Up Flat Folding Explorer Robot (PUFFER), and an application of the method to assess survivability under lunar impact scenarios. A numerically stable and computationally efficient model of rigid-flex PCB robotics was permitted by using a combination of pre-existing element types and a hyperelastic material model for the flexible hinges.

Published: February 2024

A fast method for predicting turbofan fan-stage broadband interaction noise is being developed. The downstream propagating acoustic power in the bypass duct due to the response of the fan exit guide vane (FEGV) to fan wake turbulence is computed based on two-dimensional flat-plate cascade analysis and Green’s method. This study focused on using machine learning to define the fan wake parameters used as inputs to the FEGV response and noise calculation. Machine-learning algorithms are being trained using computational fluid dynamics results. This paper describes the accuracy of machine learning given the available rotor wake data. Further, the effect of errors in the learned input data on the acoustic prediction was studied. Based on this study, the method shows great promise.
Tip Vortex Study of a Rotor with Double-Swept Blade Tips
Authors: Wolf C. Christian , Braukmann Johannes N. , Müller Martin M.
Published: February 2024

An experimental aerodynamic study was conducted, analyzing the wake structure of a four-bladed model rotor with a forward-backward swept tip geometry inspired by the ONERA-DLR “Etude d´un Rotor Aéroacoustique Technologiquement Optimisé”-design. Similar tip designs are used on some modern helicopter main rotors. The experiments were conducted at the Rotor Test Facility Göttingen (RTG) in hover-like conditions using a stereoscopic high-speed particle image velocimetry system. The results are compared with those of a reference rotor using a conventional parabolic blade tip. The test parameters include both constant-pitch cases and pitch-oscillating cases with a cyclic swashplate input. The constant-pitch tests show a two-step stall behavior for the double-swept tip, with the first step characterized by a reduced thrust slope and a reduced rotor efficiency. This effect is explained by a repositioning and a structural change of the tip vortex generation. The pitch-oscillating cases show that the double-swept tip results in an earlier tip stall compared to the parabolic geometry while maintaining high thrust levels. The dynamic tip stall yields a break-down of the wake’s tip vortex system, which is replaced by a spanwise band with small-scale turbulent structures and trailed vorticity, but no large-scale vortices.
Order-of-Magnitude Improvement in Electroaerodynamic Thrust Density with Multistaged Ducted Thrusters
Authors: Gomez-Vega Nicolas , Barrett Steven R. H.
Published: February 2024

Electroaerodynamic (EAD) thrusters ionize atmospheric molecules and accelerate the ions in an electric field; collisions of ions with neutral molecules induce a flow and produce a thrust force. EAD thrusters can be nearly silent as they do not contain moving parts. It has been shown that EAD can be used to propel an airplane; however, improvements in thrust density are needed for practical applications. We recently proposed using multistaged ducted (MSD) EAD thrusters to improve performance: these devices enclose several serial EAD stages in a duct that contains an inlet and a nozzle. The duct can theoretically contribute to thrust and be used to control the flow properties. Here, we conduct experiments with single-stage and MSD thrusters with up to 10 stages using corona discharges as the ion source. Our 10-stage thruster can produce a thrust per unit cross-sectional area of up to [Formula: see text]. This is an order of magnitude higher than that used to fly the first EAD-propelled airplane and is achieved at a similar thrust-to-power ratio. We also compare the experimental results to the predictions from theoretical models and show that these agree with a coefficient of determination of 0.994, providing a means for quantitative design and optimization.

Technical control is an integral part of the production process. The main task of technical control at the enterprise is the timely receipt of complete and reliable information about the quality of products, the state of the equipment and the technolog-ical process in order to prevent malfunctions and deviations that may lead to violations of the requirements of standards andtechnical conditions. In mechanical engineering, it is a set of control operations that are performed at all stages of production by various departments of the enterprise depending on the object of control.Technical control ensures the necessary configuration of the production process and maintains its stability, i.e. stable repeatability of each operation in the prescribed technological regimes, norms and conditions. The objects of technical control at the machine-building enterprise are materials, semi-finished products at various stages of production, finished products (parts, small assembly units, assemblies, blocks, products), means (equipment, tools, devices, devices), technological processes and processing modes, general culture of production.Therefore, improving the quality of control operations at all stages of production and quality control of finished products is a necessary condition for improving the quality and level of competitiveness of products.The work analyzes the accuracy characteristics of the main classes of car parts, which most affect its performance and durability, and which are subject to strict requirements for the accuracy of dimensions, shape deviations and mutual location, roughness, absence of defects on working surfaces, and currently existing methods and means of control cannot fully ensure the measurement of these parameters, and therefore there is an urgent need to introduce fundamentally new modern comput-erized means of their control, such as coordinate measuring machines, circular gauges, devices for controlling roughness.The article is a scientific and methodological publication

Objective: Describe the characteristics of the environment that influence the development of sand flies, and compile information about the integrative taxonomy of these insects. Bibliographic review: Sand flies (Diptera: Psychodidae: Phlebotominae) are insects, some species of which are involved in the transmission of neglected diseases such as leishmaniasis. Thus, greater attention must be paid to ecological factors and anthropogenic changes, as they have a direct influence on the presence of the vector and the adaptation of species, favoring changes in the sylvatic cycle of the disease and consequently promoting an increase in reported cases of the disease. Traditional taxonomic identification of these insects is done by analyzing morphological characters, but the use of DNA sequences has been used by researchers as an integrative approach, since molecular techniques provide reliable, fast and efficient identifications as well as the elucidation of species complexes and the discovery of new taxa, and there are good reference sequences for many species. Final considerations: Therefore, it is crucial to understand the diversity and bioecology of vectors, including integrative taxonomy, to understand and support future research to help control leishmaniasis.

The purpose of the article is to present a toolkit for analyzing changes in the system of library training, its subsequent adjustment and transformation into an effective tool for the development of the industry. The basis of this work is the monitoring of the functioning of the system of university and additional professional education (APE) in the field of “Library and Information Activities”.

To solve this task the specialists of the Russian State Library have developed and created two registers: The Register of basic educational programmes of higher education, implemented in the direction of “Library and Information Activity”, and the Register of existing educational programmes of advanced training and professional retraining for library specialists. The registers are placed in the “Library Professionals” section of the federal state information system “National Electronic Library”. A study of these registers has been carried out and their expert evaluation has been made. The result of this work may be the creation of a “map” of higher and additional professional education of Russian library professionals.

The register of basic educational programmes of higher education implemented in the field of “Library and Information Activity” contains details about 73 educational programmes of higher education of institutions from 32 subjects of the Russian Federation. The register of educational programmes of professional development and professional retraining for library specialists includes information about 241 educational programmes of additional professional development (29 professional retraining programmes and 212 professional development programmes). These programmes are implemented in 34 subjects of the Russian Federation.

The programmes of APE are analyzed. The author’s methodology of evaluation of professional retraining programmes is presented. The minimum number of points that a professional retraining programme received according to the results of the examination was 6, the maximum number of points was 43.33 (out of 50 possible).

Conclusions on the results of the expert evaluation are given. The prepared registers are presented as one of the elements of the information and educational platform of Russian libraries.
