Synthesis of Methyl-Substituted Aza[7]helicene with Enhanced Configurational Stability and Chiroptical Performance
Authors: Chen Xing-Yu , Li Ji-Kun , Wang Chan , Wang Xiao-Ye
Published: January 2024

As an important building block, aza[7]helicene (A7H) plays a crucial role in constructing chiral conjugated molecules. However, the poor configurational stability of A7H makes it easily racemize, thus limiting its applications in chiroptical materials. In this work, we design and synthesize tetramethyl-substituted aza[7]helicene (TMA7H) to improve the configurational stability. Experimental results demonstrate that the racemization energy barrier (at 25 ℃) is significantly enhanced from 29.5 kcal mol-1 for A7H to 41.0 kcal mol-1 for TMA7H, indicating the higher configurational stability of enantiopure TMA7H which can keep its chiral configuration even at high temperatures. For instance, at 150 ℃, the racemization half-life of TMA7H is determined as 4.2×103 h (about six months), which is three orders of magnitude longer than that of A7H (1.1 h). Furthermore, TMA7H exhibits stronger circular dichroism responses and circularly polarized luminescence with higher dissymmetry factors, making it a superior building block for chiroptical materials.

Published: January 2024

Here, we report the synthesis of BCN-93, a meltable, functionalized and permanently porous metal-organic polyhedron (MOP), and its subsequent transformation into amorphous or crystalline, shaped, self-standing, transparent porous films via melting and subsequent cooling. The synthesis entails the outer functionalization of a MOP with meltable polymer chains: in our model case, we functionalized a Rh(II)-based cuboctahedral MOP with polyethylene glycol (PEG). Finally, we demonstrate that once melted, BCN-93 can serve as a porous matrix into which other materials or molecules can be dispersed to form mixed-matrix composites. To illustrate this, we combined BCN-93 with one of various additives (either two MOF crystals, a porous cage, or a linear polymer) to generate a series of mixed-matrix films, each of which exhibited greater CO2 uptake relative to the parent film.

Authors: Zhang Wenjun , Yao Zhikun , Burton Lee
Published: January 2024

In this paper we investigate the relationship between the conductivity effective mass and exfoliation energy of materials to assess whether automatic sampling of the electron band structure can predict the presence of and ease of separating chemically bonded layers. We assess 22,976 materials from the Materials Project database, screen for only those that are thermodynamically stable and identify the 1,000 materials with the highest standard deviation for p-type and the 1,000 materials with the highest standard deviation for n-type internal conductivity effective mass tensors. We calculate the exfoliation energy of these 2,000 materials and report on the correlation between effective mass and exfoliation energy. A relationship is found which is used to identify a previously unconsidered two-dimensional material and could streamline the modelling of other two-dimensional materials in the future.

Authors: Ohnuki Yuto , Akiyama Manato , Sakakibara Yasubumi
Published: January 2024

Motivation: Computational techniques for drug-disease prediction are essential in enhancing drug discovery and repositioning. While many methods utilize multimodal networks from various biolog-ical databases, few integrate comprehensive multi-omics data, including transcriptomes, proteomes, and metabolomes. We introduce STRGNN, a novel graph deep learning approach that predicts drug-disease relationships using extensive multimodal networks comprising proteins, RNAs, metab-olites, and compounds. We have constructed a detailed dataset incorporating multi-omics data and developed a learning algorithm with topological regularization. This algorithm selectively leverages informative modalities while filtering out redundancies. Results: STRGNN demonstrates superior accuracy compared to existing methods and has identified several novel drug effects, corroborating existing literature. STRGNN emerges as a powerful tool for drug prediction and discovery. The source code for STRGNN, along with the dataset for perfor-mance evaluation, is available at https://github.com/yuto-ohnuki/STRGNN.git.
Implications of Efficient and Selective NO and NO2 Detection via Surface Functionalized h-B2S2 Monolayer
Authors: Nath Upasana , Sarma Manabendra
Published: January 2024

The advent of two-dimensional (2D) materials has ushered in a novel era in materials science, owing to their unique physical and chemical features. The boron-sulfide (B2S2) monolayer is a promising new addition to MoS2-like 2D material with a lighter element, boron (B), having similar valence electrons between Mo and B2 pair. In the present study, we have functionalized the h-phase boron sulfide monolayer by introducing an oxygen atom called Oh-B2S2 and elucidating the structural properties, stabilities, and electronic characteristics of this modified configuration. The charge carrier mobility of the system was found to be 790 × 102 cm2 V-1 s-1, which is much higher than the mobility of the MoS2 monolayer (200 cm2 V-1 s-1). The potential application of the 2D Oh-B2S2 monolayer in the realm of gas sensing was evaluated using a combination of density functional theory (DFT), ab initio molecular dynamics (AIMD), and non-equilibrium Green’s function (NEGF) based simulations. Our results imply that Oh-B2S2 monolayer outperform graphene and MoS2 in NO and NO2 selective sensing with higher adsorption energies (-0.56 and -0.16 eV) and charge transfer values (0.34 and 0.13 e). Further, the current-voltage characteristics show that the Oh-B2S2 monolayer may selectively detect NO and NO2 gases after a bias of 1.4 V, making a boron-based gas-sensing device a greater possibility in future nanoelectronics.

Published: January 2024

In this work, we conducted a detailed investigation into the optical properties of all-inorganic perovskite (CsPbBr3) precursors. The absorption, photoluminescence (PL), and photoluminescence excitation spectra of the precursors were analyzed in a broad concentration and various solvents. In specific solvents (such as DMSO, DMF, and NMP), the CsPbBr3 precursor gradually transformed from solution into a colloid and exhibited aggregation-induced emission (AIE) as the concentration increased, and the luminescence intensity and color of the colloid could be controlled by changing the solvent and precursor ratio. Understanding the optoelectronic properties of the precursor may provide deeper insight into the mechanisms that govern the formation and crystallization processes of perovskites, which is vital for the solution-process device performance. Besides, we discussed the difference between the aggregates in the organic system (such as TPE) and the inorganic system (such as CsPbBr3).
OSA in Patients with Severe Asthma-Alternative Overlap Syndrome
Authors: Čekerevac Ivan , Djokić Bojan
Published: January 2024

Bronchial asthma and obstructive sleep apnea (OSA) are common chronic diseases of the respiratory system. During the last decade, there has been a growing interest in the connection between these two disorders. Studies show that asthma patients are at increased risk for OSA, and the prevalence is on average around 70% in severe asthma patients. Rhinitis, gastroesophageal reflux disease and obesity are common comorbidities for both entities. OSA is an independent factor in the exacerbation of asthma and each condition in itself can contribute to the exacerbation of the other. Asthma, by its mechanical effect, has a direct impact on OSA, leading to greater collapse of the upper airway and worsening snoring and apnea symptoms in patients with OSA. On the other hand, OSA directly affects asthma through nerve reflexes, intermittent hypoxia, increases inflammation, increases the production of leptin and vascular endothelial growth factor as well as sleep fragmentation. Indirect effects in a bidirectional interaction are reflected in the prolonged effects of systemic corticosteroids, chronic diseases of the upper respiratory tract, tobacco use and increased body weight in asthmatics, which leads to worsening of OSA symptoms. It remains unclear whether OSA in asthmatics is merely a comorbidity or a specific new phenotype of asthma. In patients with asthma and OSA, CPAP treatment reduces asthma symptoms, improves morning expiratory flow, and improves quality of life parameters.

Published: January 2024

Background: Ankle Foot Orthoses (AFO) is mostly advised for a stroke patient who is complicated with plantarflexion deformity, to support and improve the alignments of the feet for reducing knee joint extension and promoting hip joint extension through stance-phase. Objective: To provide deeper knowledge using software gait analysis for the biomechanical effects of PLS AFO for stroke patients. Patients and Methods: We divided 42 participants into 3 groups (the first and second groups were 28 stroke participants that used AFO and with OUT-AFO and the third group was 14 normal participants without deformity. All participants walk 10 meters in a straight line for the same time their gait was captured at Comfortable Walking Speed (CWS). Temporal-spatial and kinematic parameters of the knee joint were compared in the study. Results: The PLS AFO showed improvement in knee ROM in the AFO condition that has better knee flexion in the early stance (from 8.16 to 16.24 degrees in the AFO condition), a huge increase in the late stance of knee extension (from 0.16 to 3.82 degrees) and better knee flexion than the barefoot condition in the swing flexion (from 26.1 to 39.78 degrees). Also, the mean Time Up and Go (TUG) identically decreased in stroke participants (from 36.04 s in OUT-AFO to 22.6 s in AFO condition). Conclusion: In this study, we showed that using a PLS AFO can be beneficial for improving knee ROM and progress walking speed, gait symmetry, balance, and reducing the risk of falls.

Low-Cost Laboratory Data Acquisition System Based on the Z8 ENCORE!â„¢ Microcontroller for pH Measurement
Authors: De Vera Ian Mitchelle S. , Chainani Edward T.
Published: January 2024

A pH measurement-auto-titration data acquisition system based on the Z8 Encore!â„¢ Z8F6401 Flash microcontroller was devised with a glass electrode acting as a pH sensor. The data acquisition system allows buffer calibration, pH measurement of samples and the option to perform an automated strong acid-strong base titration via a solenoid pinch valve which actuates the flow of titrant. The results given by the pH measurement system were comparable to that of SartoriusÂ® PB-20 pH meter using t-Test within the pH range 4.00 to 10.00. This can be attributed to the very linear response of the sigma-delta analog-to-digital converter (ADC) of the Z8F6401 to changes in potential. The auto-titration setup gave an accurate titrant volume delivery to the bromothymol blue endpoint (pH 6.2 to 7.6) for a strong acid-strong base titration.
Controlled Release of Methyl Salicylate in Chitosan-Poly(N-Isoporpylacrylamide) Semi-Interpenetrating Networks
Authors: Henares Terence G. , Cuyegkeng Ma. Assunta C.
Published: January 2024

A semi-interpenetrating network (semi-IPN) was produced by polymerizing N-isopropylacrylamide (NIPAAm) in the presence of chitosan and cross-linking agent, ethylene glycol dimethacrylate (EGDMA). The resulting material did not swell as much as poly(N-isopropylacrylamide) (pIPAAm), but still showed temperatute- and pH- responsiveness. Swelling and differential scanning calorimetry(DSC) experiments showed that the lower critical solution temperature (LCST) of the material was at 31 C. The semi-IPN was swollen below 30 C but started to collapse at this temperature. This is in the same range as the LCST of carrageenan-pIPAAm semi-IPN. The chitosan-pIPAAm semi-IPN was in a collapsed state and reached maximum swelling at pH 9 whereas pure pIPAAm and pure chitosan both became swollen at a lower pH.Methyl salicylate was absorbed by the semi-IPN. Its release was monitored with respect to temperature. The temperature-responsive release of methyl salicylate was more pronounced at the LCST of 31 C.

Published: January 2024

Human milk oligosaccharides (HMOs), although considered indigestible to the infant, are the third most abundant solid component of breastmilk. They serve many health-related functions benefitting the infant, such as nourishment of gut bacteria, inhibition of pathogenic infection, and aiding in brain development. In this study, a rapid-throughput analytical method is validated for Filipino breastmilk HMOs. The method entails lipid extraction by centrifugation, protein precipitation using ethanol, alditol sugar reduction using sodium borohydride, and solid phase extraction purification using porous graphitized carbon, all in a 96-well plate format. Nano-HPLC Chip/TOF-MS, coupled with the use of Agilent MassHunter programs for filtering datasets using an in-house library, is then used to analyze purified HMOs. The results evidently show that the rapid-throughput method minimizes sample loss, ensures reproducible MS signals, and considerably shortens sample handling time. Furthermore, the method significantly reduced analysis time 5-fold and eliminated the individual sample preparation, which enabled simultaneous analysis of 386 samples (four 96-well plates) in a single run.  Thus, the rapid-throughput analysis is highly efficient and effective for the profiling and structural determination of Filipino breastmilk HMOs even in large sample population sets.

Authors: Opona Abegail Joyce , Sanchez Joje Mar , Bondoc Kim
Published: January 2024

Teaching and learning in chemistry have been shifted to online classes due to the pandemic. With this, researchers investigated the use of multiple representations embedded to determine its effectiveness in online learning setup. A pretest-posttest with control quasi-experimental design was employed to two groups of Grade 11 STEM students taking up a general chemistry course in a private secondary institution in Cebu City, Philippines. The control group (n=30) was exposed to typical online class while the experimental group (n=30) was exposed to the multiple representations. Study findings revealed that there have been significant mean gains for both groups, indicating the important role of online learning in chemistry. The experimental group (MD=3.03, t=2.495, p=.015) had significantly higher mean gains than the control group, signifying the more effective nature of multiple representations in chemistry teaching. Moreover, the students had highly favorable attitudes towards multiple representations and had average extents of understanding in the macroscopic, microscopic, and symbolic levels. Therefore, the use of multiple representations promotes studentsâ€™ chemical understanding during the Covid-19 pandemic. The researchers recommend the use of these representations in chemistry teaching, where teachers start at the macroscopic level before they proceed to the more abstract levels.

Published: January 2024

Higher intake of plant protein is associated with lower risk in degenerative diseases caused by oxidative stress, thereby placing enormous demand in the identification of plant-based sources of protein like legumes. Rice bean (Vigna umbellata) is known to be a great source of low-cost and good nutritional quality protein for utilization in food products. This study characterized the soluble and hydrolyzed proteins from rice beans and assessed their antioxidant properties in vitro. The total soluble proteins from the rice bean were extracted using 35 mM potassium phosphate buffer (pH 7.2 M, 0.40 M NaCl) affording a concentration of 1.23 mg/mL. The isolated proteins were purified by a combination of gel filtration chromatography, ammonium sulfate precipitation and dialysis. SDS-PAGE was performed to monitor the changes in the protein profile after every purification step. Enzyme hydrolysis was also done using pepsin and a mixture of trypsin, chymotrypsin and thermolysin. The antioxidant activity of the protein extract and digest after 4 h of hydrolysis were determined using 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging assay, and found to be 35.11% and 19.68%, respectively. The results indicate that rice beans can be utilized as a rich source of protein with antioxidant properties and can be a rich source of functional foods.

This study investigated the effectiveness of the electronic strategic intervention material Gas Rules! in teaching Ideal Gas Laws to grade 10 students. A quasi-experimental design was used, with 15 participants in a control group exposed to a modular approach and 15 in an experimental group exposed to the E-SIM. The instruments used for data collection were an entry/exit test and a perceptions questionnaire. Descriptive statistics and non-parametric tests were used for data analysis. Results showed that the modular approach and E-SIM effectively improved students' conceptual understanding of gas laws. However, the E-SIM enhanced students' conceptual understanding more effectively than modules. Additionally, students had positive perceptions of the E-SIM, and there was a significant correlation between their perceptions and conceptual understanding. The study concluded that the Gas Rules! E-SIM is an effective and superior tool for teaching gas laws to grade 10 students in basic education. Future research could investigate the impact of E-SIMs on students with different learning styles and abilities.

A hiperplasia fibroadenomatosa mamária (HFM) se caracteriza por rápida hipertrofia e hiperplasia do estroma e epitélio ductal das glândulas mamárias. Ela corresponde a 20% dos nódulos mamários e ocorre com maior frequência em felinos, fêmeas e jovens. Diante da elevada casuística de HFM, este estudo objetivou relatar um caso de sucesso terapêutico de HFM em uma gata, utilizando o procedimento de ovariohisterectomia (OH) associado a um fármaco antagonista de progesterona, a fim de contribuir com o esclarecimento quanto aos sinais clínicos, diagnóstico e tratamento desta afecção. Uma gata, sem raça definida, com sete meses de idade e 2,9 kg de peso vivo, apresentou aumento de volume das glândulas mamárias uma semana após o primeiro ciclo estral. Foi negado o histórico de acasalamentos e uso de contraceptivos. Todas as glândulas mamárias se encontravam hiperplásicas de forma assimétrica, cianóticas, consistência firme, alopécicas, com diâmetro variando entre 2,5 cm a 4 cm, ausência de aderências, com sensibilidade dolorosa à palpação. A gata foi diagnosticada com HFM por meio dos sinais clínicos, histórico e citopatologia. O protocolo terapêutico consistiu em OH associada ao uso de aglepristone. Ressalta-se que este protocolo é uma boa opção quando não há interesse do tutor na reprodução do animal, oferecendo resultados rápidos, eficazes e com chances reduzidas de recidivas.

Descrevem-se achados morfológicos de lesões traumáticas em animais de vida livre provenientes de uma área desmatada no estado do Ceará. Durante quatro meses, foi percorrida uma área de aproximadamente 400 hectares, na região do Baixo Jaguaribe, Ceará, Brasil. À medida que eram coletados, os animais eram encaminhados para identificação. Foram coletados apenas os animais encontrados mortos e, posteriormente, foram alocados em grupos de lesões pré-estabelecidas caraterizadas como: fraturas únicas, fraturas múltiplas, lesões craniais, mutilação, alterações cadavéricas, sem alterações, outros. Foram encontrados 342 animais, dos quais 96,78% corresponderam a répteis, 1,46% a anfíbios e 1,75% a mamíferos. Dentre os répteis, as famílias Amphisbaenidae (91), Teiidae (59), Dipsadidae (57) e Tropiduridae (35) foram as mais afetadas, enquanto anfíbios (Hylidae e Leptodactylidae) e mamíferos (Didelphidae, Dasypodidae e Caviidae) foram os menos observados. Lesões traumáticas equivaleram a aproximadamente 54% das lesões observadas, e corresponderam a fraturas, mutilações e politraumatismos. Considerando-se as fraturas e traumatismos, observou-se que aproximadamente 80% dessas categorias acometiam as regiões abdominal, pelve, membros posteriores e cauda, categorizando-se como traumatismo espinal-medular. Essas lesões podem ser observadas em animais domésticos decorrentes do atropelamento, contudo, são pouco descritas em animais silvestres e podem estar associadas a atividades antrópicas diversas, como o desmatamento. Este trabalho pode contribuir para estudos futuros sobre os indicadores do desequilíbrio ambiental. O diagnóstico patológico em animais de vida livre é um importante indicador de alterações ambientais e pode auxiliar no controle de óbitos nesses indivíduos.

Authors: Siva Subramanyam Reddy
Published: January 2024

This paper presents a hybrid algorithm using a Hybrid Firefly and Particle Swarm Optimization (HFPSO) algorithm to determine the optimal placement of SSSC devices. A multi-objective function is used to increase voltage stability, voltage profile and minimize overall power losses of the transmission system. At first, PSO algorithm is used to find the optimal SSSC location and further more to reduce the power losses and voltage profile enhancement to overcome the sub-optimal operation of existing algorithms. The HFPSO algorithm is used to determine the optimal placement of SSSC series FACTS device and verification of the proposed algorithm was achieved on standard IEEE 14-bus and IEEE 30-bus transmission systems in the MATLAB environment. Comprehensive simulation results of two different cases show that the proposed HFPSO demonstrates significant improvements over other existing algorithms to enhance voltage stability and reducing active and reactive power losses in electrical power transmission systems.

Published: January 2024

To address the complexity of the departmental coordination with others effectively, an approach for selecting emergency alternatives based on multi-granularity linguistic and multidivisional cooperation was presented. Firstly, multi-granularity linguistic phrases were employed to express the preference information, and some transformation functions were used to unify the multi-granular linguistic phrases into a uniform linguistic label set. Secondly, the evaluation indexes of key attributes with respect to each combination of alternations were determined considering multidivisional cooperation. Furthermore, according to the evaluation indexes and the weight vector of key attributes, the comprehensive value of each combination alternative was determined to obtain the best alternative. Finally, a case study of low-attitude airspace emergency rescue after an earthquake is presented to illustrate the validity of the approach.

Authors: Gardapandawa Budi Setiawan , Wastap Jaeni B , Saleh Sukmawati
Published: January 2024

Panca Curiga is a method of Sundanese interpretation which is commonly used in understanding texts contained in art, especially in rumpaka songs. The existence of discourse about Panca Curiga in society until now has only been limited to discussion without scientific investigation. Efforts to understand how to interpret rumpaka, especially in art whose creator is unknown, has its own complexities. This can be seen from the rumpaka-rumpaka that appeared before the rise of artistic industrialization, for example in the Sundanese art of pantun or kawih kaulinan barudak. From the results of the study based on the application of Panca Curiga to the rumpaka pantun and kawih kaulinan barudak models, Panca Curiga actually has many similarities with the disciplines of interpretive methods such as Hermeneutics and Semiotics. Therefore, Panca Curiga can be an opportunity to be used to study rumpaka texts in Sundanese art.

Published: January 2024

The subject of the study is the tax tools used to facilitate the implementation of the tasks of national projects. The purpose of the work is to assess the stimulating effects of personal income tax in the context of the implementation of national projects. The article considers national projects that are part of the "Human Capital" block and are of a social nature. The potential opportunities have been identified and the real results of using the stimulating effects of personal income tax to help achieve the targets of the national projects "Healthcare", "Education" and "Demography" have been revealed. The conclusion is made about ensuring greater efficiency in achieving the targets of national projects of direct budgetary mechanisms against indirect tax instruments. At the same time, it is determined that tax instruments that entail less burden on the budget system can also contribute to achieving the goals set. It is concluded that, despite the opportunities available in the personal income tax system due to the provision of social and standard tax deductions for children, they are not fully implemented and do not contribute to achieving the goals of national projects. It is necessary to improve the procedure for personal income tax taxation both in terms of bringing the amount of tax deductions provided in line with the real cost of treatment and education services, and in terms of indexing the amounts of standard deductions for children with a focus on their provision to the least well-off segments of the population, which is achieved by simultaneously increasing the amount of deductions provided and limiting the amount of annual income that allows you to qualify for receiving such deductions.

The socio-economic development of the Arctic zones of Russia is carried out in accordance with the federal projects included in the national projects, for the implementation of which programs are being developed aimed at ensuring the achievement of the set goals in a timely manner, which are legally enshrined in federal projects, for example, in the federal project "Development of the Northern Sea Route". The subject of the study is the influence of negative factors on the timing of the implementation of targeted programs aimed at the implementation of national projects. The purpose of the work is to develop a mechanism for assessing the impact of program projects on the completion date of target programs through the use of a risk matrix. The scientific novelty and practical significance of the research consists in the proposed mechanism for constructing a risk matrix of software projects based on the integration of expert assessments, special evaluation scales, an optimization economic and mathematical model and project risk matrices based on a step-by-step algorithm for evaluating software projects and their positioning in the risk matrix. The numerical example makes it easy to master and apply the proposed risk accounting mechanism in the practice of planning and implementing national projects.

Published: January 2024

The content of the tasks of the National Anti-Corruption Plan for 2021-2024 testifies to the dissatisfaction of the federal government with the results of the measures taken to minimize corruption phenomena in the spheres of state and municipal service. The subject of the study of the article is the suppression of abuse of official position by persons with authority and rights entrusted to them for personal gain. The purpose of the work is to develop organizational and legal measures to improve the management of the public civil service system and personnel in general and anti-corruption activities in particular. The dynamics of corruption crimes over the past few years is given, indicating a significant scale of corruption in government and other structures. Attention is drawn to the shortcomings of the Russian model of public civil service and personnel management. The expediency of including the norms of ethical behavior in the activities of state (municipal) employees in the legal framework and preventing the occupation of public positions by persons with pronounced egocentric character traits and a deformed system of moral values is substantiated. The reasons for the need to change the model of declaring information about property and transactions with it are given. It is proposed to improve, by modifying the BC Certificate, the procedure for declaring information about property by applicants for public positions and civil servants. Based on the analysis of the tasks of the National Anti-Corruption Plan for 2021-2024, conclusions are drawn that they are closely interrelated and justified through the analysis of legal systems and practices of foreign countries, as well as recommendations of key international organizations.

RUSIA–UCRANIA: ¿ES UNA GUERRA TRIBUTARIA?
Authors: Sanz Jofré Jorge , Martínez Toro Javiera , Ibáñez Guzmán Javier
Published: January 2024

La guerra Rusia–Ucrania comenzó como parte del desarrollo de una guerra híbrida llevada adelante por Rusia a través de la ocupación de Crimea y el Donbás en 2014, y que, al no poder conquistar los objetivos políticos planteados, como la instalación en Ucrania de un gobernante proruso, rompe el derecho internacional e invade militarmente la soberanía ucraniana.

La reacción de Occidente (EE. UU.–U.E.), no estuvo en la apreciación rusa y durante un año se ha visto enfrentada a una guerra de resistencia que no puede romper. En el tiempo, la invasión rusa ha sido enfrentada y detenida, Rusia ha sido sancionada por el mundo occidental y paralelamente se aprecia que su principal aliado, China, se ve indirectamente afectado al no poder avanzar con su proyecto de la Ruta de la Seda hacia Europa.

Estados Unidos busca el desgaste de Rusia a través de las sanciones y la resistencia militar ucraniana con equipamiento occidental, la sobreproducción de la industria militar rusa afectada por la falta de materias primas y, probablemente iluminado por un objetivo mayor ubicado en el Indo–Pacífico referido a mantener la condición de primera potencia mundial; por tanto, ¿es la guerra Rusia-Ucrania una guerra tributaria de un conflicto mayor en el Indo–Pacífico?
