Rumo a uma Educação Intercultural em Moçambique
Authors: Vicente José Armando , Campos Maria Aparecida Santos e
Published: October 2022

Estudo qualitativo, descritivo da influência do etnocentrismo português em Moçambique, iniciado no século XV com a colonização, que impôs a cultura portuguesa em detrimento da cultura ancestral Moçambicana inferiorizando os povos e cultura nativa, considerando-lhes incultos, pagãos. A criação da escola oficial se converteu em um instrumento de alfabetização e dominação colonial, impondo a cultura e a língua portuguesa, objetivando a negação das culturas e religiosidades moçambicanas. O objetivo deste trabalho é analisar a influência do etnocentrismo português confrontado com a cultura ancestral de Moçambique. Os resultados mostraram que é imprescindível desenvolver uma educação capaz de compreender as múltiplas dimensões e a complexidade da cultura Moçambicana.

El espacio Atlántico/Caribe guatemalteco: una construcción histórica y territorial liberal 1871-1959
Authors: Véliz Catalán Néstor
Published: October 2022

La motivación central de este artículo reside en explicar la forma en que se construyó la representación del territorio caribeño de Guatemala desde 1871. Esta orientación conlleva a cuestionar la forma en que la oficialidad denominó este espacio, lo que implica inquirir sobre el sentido discursivo, ideológico y político de nombrarlo como “Atlántico”.  Ello remite a revisar las tendencias de los movimientos de asentamiento urbano y construcción de vías de comunicación desde la época colonial. Subyace la tesis de que, la denominación antes expresada, obedece a una certeza de parte de los intelectuales liberales de llamar el espacio caribeño de la forma citada al considerar que las aguas que lo bañan constituyen un espacio común con Europa occidental, paradigma civilizatorio. La reproducción de dicha forma de nombrar el espacio tiene lugar con la pervivencia de un discurso excluyente que llevó a asumir la región como “ventana” hacia Europa, obviando el contexto inmediato.

Published: October 2022

In this work, we are interested in finding new catalysts for catecholase, whose principle is based on the oxidation reaction of catechol to o-quinone. We approached the synthesis of the threes tripod ligands based on pyrazole in a condensation reaction and its characterization by IR, 13C NMR, 1H NMR spectroscopy, then we evaluated the catalytic properties of certain complexes formed in situ to catalyze the oxidation reaction of catechols to o-quinones. The aim is to find the right models to reproduce the catalytic activity of the enzyme (catecholase), we used complexes formed in situ by pyrazole derivatives with Copper salts. Among these complexes, the complex L4/Cu(CH3COO)2 showed good catalytic activity of the combination (1ligand/2metal) in MeOH for this reaction, with a speed Vmax equal to 69.38 μmol.L-1.min-1 and a low value of Km equal to 0.019 mol.L-1. We have demonstrated that the nature of concentration, ligand, solvent, and copper salts, influenced strongly the catecholase activity.

Published: October 2022

Liquified petroleum gas (LPG) storage tanks are essential components for storing and distributing fuels. However, system failures due to inspection flaws increase the risk of leaks, fires, and explosions. Therefore, this study discussed the development of a safety system application applied to LPG storage tanks based on a risk-based leak (RBL) analysis. Data associated with risk factor values were obtained from an LPG storage tank in a gas distributor company. The risk of failure was calculated by analyzing the probability of failure (PoF) and the consequence of failure (CoF). The results showed that the level of risk observed was medium-high with a PoF in category 1 at a total damage factor value of 1. Furthermore, the CoF in category E was positioned with a consequence analysis value of 2381.29 m2 with an LPG storage tank life span of 33.5 years and an external inspection interval of five years.

Published: October 2022

The need for energy and electricity has been increasing globally, and this means more power is required from the power plants. Power plants, however, will then continue harming the earth because of the greenhouse gasses produced while generating energies that contribute to global warming. Using renewable sources to produce clean energies is one of the sustainable methods to deal with such challenges. Wind energy is one of the renewable sources, which is accessible anywhere on earth, creating green energy. Wind turbines are mainly categorized into Horizontal Axis Wind Turbines (HAWT) and Vertical Axis Wind Turbines (VAWT). This paper firstly presents a general comparison between the HAWTs and VAWTs. Then, it presents mathematical modelling for the aerodynamic factors of HAWT and Darrieus VAWT to assist the researchers to understand some key design aspects of wind turbines, such as lift/drag ratio, tip speed ratio, power coefficient, and torque coefficient. Also, this paper presents a review of the aerodynamic performance of the recent VAWT designs to help researchers to identify and choose the best model among the Savonius and Darrieus rotors for further development or designing a new model at different wind conditions. This comparison review shows that for a large scale HAWT upwind 3 bladed wind turbines are the most optimum. The helical Savonius rotors perform better by having positive torque coefficient at all azimuth angles. Moreover, helical Darrieus was found to produce lesser noise and suitable for conventional areas. hybrid Savonius-Darrieus rotors can solve the self-starting challenge of the VAWTs, and they are suitable at low wind speeds. At last, this review shows some of the recent hybrid Savonius-Darrieus rotors which would help to solve the low efficiency of Savonius rotor and self-starting challenge of Darrieus rotors.

Authors: Nandi N. , Dede M.
Published: October 2022

Urban heat island (UHI) is a significantly increasing temperature that occurs in the urban region due to urbanization and anthropogenic activities. The UHI represents environmental quality decrease and able to change a microclimate in the long term. It phenomenon can be estimated using multi-temporal remote sensing imagery data. This study aims to analyze the spatial dynamics of UHI in the urban region of West Java from 1998 to 2018. We only used remote sensing data from different datasets. Information of land-surface temperature is extracted from Landsat-5 TM and Landsat-8 OLI images using radiative transfer equation which validated using MODIS data in the same period. This study showed that UHI intensity in the urban region of West Java reach 5.11oC in 2018. For 20 years, the land-surface temperature increased to 4.44oC. The UHI distribution is concentrated in the central business district, industrial area, harbor, terminal, airport, and traffic jam zone. The UHI significantly increased in Depok and Cimahi, which are known as satellite cities for the surrounding megapolitan (Jakarta and Bandung Raya). This model has high validity result with a correlation value of 0.74. The UHI management is important to strengthen urban resilience in the environmental field through green open space, green belts, roof gardens, land use and land cover formal direction, and the use of high albedo materials to build construction.

Myristica fragrans Houtt (belongs to the Myristicaceae family) is a Maluku Island (Indonesia) native plant. The seed of M. fragrans (Nutmeg) has been used for medicinal benefits. M. fragrans also has anti-cancer properties. The goal of this research was to use computer-aided drug design to investigate the in silico molecular docking of selected nutmeg compounds against Caspase-3. Molecular docking using Malegro Virtual Docker (MVD) software Ver 5.5 was performed to investigate binding complicated models to offer information on critical drug-receptor interactions. The most potent ligand was Licarin B, which had a docking score of -103.07 kcal/mol. The Licarin B structure formed several hydrogen bonds with Trp214 and Phe250. These findings imply that the nutmeg seed contains a prospective compound that could be a great anti-cancer agent.

Published: October 2022

Wearable robots are commonly used for rehabilitation and they are made to fit the human body to assist persons who are unable to help themselves. The design of controllers became necessary to enhance the dynamic motion of these exoskeleton systems when worn by patients. In this study, active disturbance rejection control (ADRC) with reduced-order extended state observer (RESO) has been proposed for motion control of exoskeleton knee-assisting device to eliminate the phase lag induced by full-order extended state observer (FESO). The design analysis of RESO-based ADRC has been presented and a computer simulation has been conducted to verify the effectiveness of the proposed controller. A comparison study has been made between ADRC based on RESO and that based on FESO in terms of transient and robustness characteristics. The simulated results showed that the RESO-based ADRC gives better transient and load rejection capabilities compared to the controller with FESO.

Published: October 2022

In the last decade, the search for cleaner fuels like biodiesels is gaining wide popularity, and exergy analysis are widely used in design and performance evaluation to identify the various losses. In this study, three neat biodiesels are tested for energy and exergetic performance in a single-cylinder, four-stroke IDI diesel engine. The experiments are conducted for waste poultry fat biodiesel (WPFBD), palm oil biodiesel (POBD), and waste cooking oil biodiesel (WCOBD) at various loads by maintaining a fixed rpm of 1500. Parameters like exergetic efficiency, exergy destruction, and various heat loss factors are computed from the thermodynamic models. The in-cylinder combustion pressures, heat release rate, and fuel consumption are also measured. Results show that WCOBD dominates the other two biodiesels by achieving high exergetic efficiency (52.74%) and low exergetic destruction (3.74 kJ). The in-cylinder combustion pressures and net heat release for WCOBD show smoother combustion with better torque conversion. In contrast, POBD shows high fuel consumption and more unaccounted heat losses. Better utilization of heat input by converting it into useful work was achieved for WCOBD at 75 and 100% loads. Similarly, the exhaust emissions from WCOBD compared with diesel fuel at all the loads reveal that except for NOx, there is a drastic reduction of CO, UHC, and exhaust smoke.
Sensitivity of Junction Width to Tidal Nonlinearity on Small and Shallow Tidal Junction
Authors: Khadami Faruq , Kawanisi Kiyosi , Al Sawaf Mohamad Basel , Gusti Gillang Noor Nugrahaning
Published: October 2022

Observations of water elevation in the short and small tidal junctions of the Ota River, Japan, showed an increase in tidal nonlinearity at the apex of the junction. To quantitatively estimate the increase in nonlinearity, the barotropic hydrodynamic model was applied in an idealized junction domain, inspired by the Ota River Estuary junction. Even though the model was simplified, it successfully reproduced the increase in nonlinearity at the junction apex. A sensitivity analysis of tidal nonlinearity to the width of the upstream channel at the junction was performed by varying the upstream channel width from the same width as the branch channel width to three times the branch channel width. The relationship between the upstream channel width at the apex and tidal nonlinearity was not linear. Tidal nonlinearity was maximized when the apex width was twice the branch channel width. The convergence of the tides in the small width junction induced an increase of some positions of quarter-diurnal tidal constituent that raised the tidal nonlinearity. In the case of a wider channel, the flushing from river runoff dampen the tidal constituents, making it decrease tidal nonlinearity

Etlingera alba (EA) is one of the endemic plants grown in Sulawesi. We determined the cytotoxic and anti-metastatic activity of isolates obtained from EA rhizome extract. IC50 value for 1,7-diphenyl-6-heptene-3-one, sitostenone, sinapyl alcohol diacetate, and sinapyl alcohol acetate were 134.59; 170 ; 128.11; and 161.96 μg/mL, respectively. The compounds also had anti-migration activity. 200-μg/mL Sitostenon exhibited the lowest migration rate (3.32%). The free bond energies of sitostenon, 1,7-diphenyl-6-heptene-3-one, sinapyl alcohol acetate, and sinapyl alcohol diacetate were -11.81; -8.25; -6.64; and -6.28 kcal/mol, respectively. All compounds were more effective in stabilizing the Matrix metalloproteinase 1 complex. Isolation from EA rhizomes have the potential to be developed as anti-metastatic for Triple-Negative Breast Cancer.

Published: October 2022

Conjugated linoleic acid (CLA) exhibits anti-cancer effects; however, most studies have only investigated its free fatty acid forms (CLA-FFA). Here, we compared the anticancer effect of CLA with its lipid forms (FFA and phosphatidylcholine [PC]) on the breast cancer cell line MCF-7 with Soy-PC as a control. CLA-FFA, CLA-PC, and Soy-PC caused a dose- and time-dependent inhibition of MCF-7 growth. However, the lowest antiproliferative activity was observed with CLA-PC. These results were consistent with Hoechst staining and protein expression of apoptosis markers Bax and Bcl-2. Interestingly, CLA-PC uptake was four times lower than that of Soy-PC, which may have affected its antiproliferative effect. Many papers showing that phospholipid forms of functional compounds have superior activity than intact forms have been reported, however, our results suggest that the PC form of CLA was inferior to its FFA form in inhibiting MCF-7 cell growth. This is the first report showing that the phospholipid form is not always the superior form.

Published: October 2022

This study aims to utilize benzotriazolium salt-ionic liquids (ILs) as solvents in the oil palm empty fruit bunch (EFB) waste pretreatment along with bibliometric analysis using VOSviewer. Three ILs have been synthesized and tested as EFB solvents by a microwave-heating method. Those are organic salts of 1,3-methyl-octyl-1,2,3-benzotriazolium ([MOBzt]+) cation with three kinds of anions such as bromide ([Br]-), acetate ([CH3COO]-), and thiocyanate ([SCN]-). The bibliometric analysis showed that new research needs to be conducted to improve the development of research relating to biomass pretreatment. The highest solubility of EFB is in [MOBzt]CH3COO is about 7,5% w/w. The effect of anions on the ability to dissolve EFB is CH3COO-SCN-Br-. When subject to ILs pretreatment, EFB exhibited increased cellulose crystallinity, changed in the structure of cellulose I to cellulose II, reduced particle size, and decreased lignin content compared to untreated one, improving the glucose yield from enzymatic hydrolysis. The highest glucose yield (1,237 mg/mL) was obtained when the EFB was pretreated by [MOBzt]CH3COO with enzymatic hydrolysis for 24 hours. This research is expected to contribute to the development of new biomass pretreatment methods.

Published: October 2022

The modification of kaolin with nano-size fillers has exhibited excellent performance in the adsorption process. Carbon quantum dots (CQDs) are the new generation of nanoparticles that have attracted interest for their utilization as modifiers. In this study, a composite of metakaolin(MK)/CQDs was synthesized and tested for methylene blue (MB) removal. The heating and acid-alkali treatment of kaolin transformed it into MK. The interaction between MK and CQDs was analyzed using XPS to detect the binding of pyridic NH2 and C-N. By loading CQDs into the kaolin matrix, the surface area was improved and the removal of MB increased. For a lower MB concentration at 5 ppm, the removal efficiency could reach 96%. The composite exhibited good regeneration through the recyclability test.

Published: October 2022

Central Sumatra basin is located on Sumatra Island, Indonesia, and is considered an oil prolific basin that produces heavy oil. The basin is believed to have unexplored heavy oil potential. Therefore, this study aims to map the heavy oil potential distribution in the basin using surface and subsurface lineaments analyses interpreted from satellite imagery and gravity data, and assisted by well log/petrophysics analysis. A thorough basin analysis was conducted based on surface/subsurface structures’ control and source rock location settings to map all potential heavy oil traps. The gravity anomaly data interpretation identified the low areas and lineaments in NW – SE, and N – S directions. The interpretation of satellite imageries showed very similar lineament patterns with the same general direction. It was observed that there is continuity between subsurface and surface lineament features, which provide contact between reservoirs and surface water sources, thereby facilitating heavy oil generation. Overlapping the lineament interpretation of gravity and satellite imagery data, supported by petroleum system understanding and verification from wells data have confirmed 7 heavy oil trap potential areas within the sedimentary basin.

Published: October 2022

We reported the simultaneous decolorization of tartrazine and H2 production via electrocoagulation and photocatalysis using CuO-doped TiO2 nanotube arrays (TNTA) composites. Tartrazine was removed by the combination of adsorption, electrocoagulation, and photocatalytic degradation, while H2 was produced through water reduction at the cathode and water splitting process on the photocatalyst surface. The photoreactor contains CuO-TNTA as a photocatalyst and is equipped with an 80-W UV lamp. Deposition of CuO on TNTA was conducted using a successive ionic layer adsorption and reaction (SILAR) method. The nanotubular of the TNTA as well as the distribution of CuO were evaluated employing FESEM and HRTEM. XRD patterns confirmed weak diffraction of CuO and TNTA revealing an anatase crystallite phase. The band gap of the CuO-TNTA was also found to be redshifted from that of pure TNTA. The simultaneous processes with the combined systems (20 V, pH = 11) managed to remove 80% of tartrazine while producing a high H2 yield (1.84 mmol), significantly higher than those obtained by each process.

Published: October 2022

The development of light-controlled electronic devices requires new possibilities of optical control via tuning of laser input parameters. Here, Fe3O4 superparamagnetic nanoparticles (SNPs) were doped with dye, and the controllability of parameters of a random laser, including the wavelength, threshold energy, and intensity under the absence and presence of an external magnetic field was studied. The prepared dye laser (Rh-640) showed strong magnetic controllability and switch ability under different pumping energies (1‒7 mJ), as well as good responsivity and durability at visible wavelengths. The applied magnetic field was utilized to modify the distribution of Fe3O4 SNPs with different concentrations and scattering behavior, altering the generation of coherent loops and laser action properties. Thus, it was possible to employ the magnetically controllable random laser in a variety of technological applications, including biology and optical communications

The objectives of this paper are to analyze the implementation and architecture of the Internet of Things (IoT) from previous studies, specifically in the world of higher education; offer recommendations for future research, as well as strengthen the theory of IoT architecture that already exists in higher education. This study employed a systematic literature review (SLR) with data collection utilizing Funnel Diagrams to select articles based on their relevance to the research question. The three publisher databases (Scopus, Emerald, and EBSCO) and index journals were utilized in the search for articles. A total of 1,200 articles were gathered from these three sources, with distributions of up to 800 in Scopus, 150 in Emerald, and 250 in EBSCO. The findings demonstrate that the existing IoT architecture has a more sophisticated model than the fundamental idea, which has three layers, implying that using IoT in education may have a significant influence on user convenience. This is due to the increasingly complicated requirements of higher education's many business procedures. This study serves as an inspiration and reference for future research for higher education institutions that include the Internet of Things in their implementation to build an efficient teaching and learning environment.

Published: October 2022

The objectives of the review were to identify different implementation aspects of the Internet of Things (IoT) in Smart Universities (SU) from diverse studies, amplify the theories behind the IoT utilization and model in SU; as well as offer recommendations for future research in this area. This study employed a systematic literature review (SLR) technique, conducting comprehensive searches of the most relevant articles to the research question published from 2018 to 2022. Following a review of peer-reviewed journals, a total of 69 refereed articles were chosen and analyzed. The findings of this study suggest that the technology model needs to be aligned and integrated with organizational processes. IoT utilization should meet the adoption readiness of a university. The results also revealed that the creation of SU can be divided into three categories: behavior, learning, educational technology, and physical facilities. However, the literature related to IoT utilization and model is still incoherent and lacking in theoretical frameworks that reflect on specific circumstances such as SU. SU research is still in its early stages, with more work to be done in terms of identifying technology model adoption. The review also contributed to serving as inspiration and a point of reference for institutions as they work with the smart university initiative to create a teaching and learning environment that is more effective and efficient.

AIM: This article discusses the significance of insulin-like growth factor 1, matrix metalloproteinase 9 and activin A levels in the blood serum and peritoneal fluid of patients of reproductive age with endometriosis in the clinical aspects of infertility and miscarriage and as per stages of the disease.

MATERIALS AND METHODS: The overall group consisted of patients with endometriosis (group I: stages III, n = 25; group II: stages IIIIV, n = 38). The control group comprised patients without the disease (group III: n = 25). The stage of endometriosis was classified during laparoscopy in accordance with revised American Society for Reproductive Medicine classification (1996).

RESULTS: In endometriosis, primary infertility predominated (up to 40.8% of cases), while secondary infertility occured in 21.2% of cases. Primary infertility accounted for 68.0% of cases in stages III versus 39.5% of cases in stages IIIIV. Secondary infertility accounted for 28.0% versus 23.0% of cases, respectively. In minimal stages of the disease, non-developing pregnancies (12.0%) and spontaneous miscarriages (4.0%) occurred in 16.0% of cases. In severe stages, these nosologies occurred in an equal percentage of cases (5.2%).

The group of patients with endometriosis showed multidirectional changes in activin A levels in the blood serum and peritoneal fluid, a decrease in matrix metalloproteinase 9 level by 27% in the peritoneal fluid and an increase in insulin-like growth factor 1 level by 36% in the blood serum. In minimal stages of endometriosis, the tendencies of changes in the parameters remained intact as compared to the overall group, the correspondence of matrix metalloproteinase 9 levels to the control values in the blood serum and peritoneal fluid being noteworthy. Stages IIIIV of the disease implied more significant changes as compared to the control or the overall group of patients. We found a decrease in insulin-like growth factor 1 level by 56% in the peritoneal fluid, a decrease in activin A level by 19% in the blood serum with an increase in the parameter by 27% in the peritoneal fluid, and a decrease in matrix metalloproteinase 9 level by 4% in the peritoneal fluid.

CONCLUSIONS: Modifications of the studied compounds activin A, MPP-9 and IPFR-1 are associated with infertility and miscarriage in patients with endometriosis.
Software as a Service (SaaS) as Cloud Computing: Security and Risk vs. Technological Complexity
Authors: Achar Sandesh
Published: October 2022

The software delivery model known as Software as a service (SaaS) has evolved from cutting-edge innovation to an essential technology for many companies. However, due to the extensive range of cloud services that companies offer as part of their SaaS offerings, it is indispensable to thoroughly comprehend the dangers associated with using these services. This article describes those dangers and recommendations for the most effective methods of control that are open to managers. This study's objective is to investigate the factors of Technological Complexity, Security and Risk, and Technical Support within an organization to determine how these factors can influence an organization's end-use intention regarding cloud technology. The availability of technical support, the complexity of use, and the organization's training have been highlighted as the most crucial factors of this aim. The findings suggest that complexity negatively influences intention to use, although training and assistance are vital, with a similar weight. Shared or collective knowledge is essential in the adoption of cloud computing technologies.
Asthma Patients' Cloud-Based Health Tracking and Monitoring System in Designed Flashpoint
Authors: Achar Sandesh
Published: October 2022

Asthma is a chronic illness that causes improper respiratory organ function and breathing problems. Three hundred fifty million people worldwide have bronchial asthma, or one in 12 adults. Self-monitoring is the first step in managing chronic illness. This lets doctors and people monitor and address health conditions in real-time. Telemonitoring is a phrase used in IT to remotely monitor the health of patients who are not in hospitals or medical centers. Wearable medical sensors, such as IoT-based remote asthma and blood pressure sensors, capture real-time information from remotely located patients. The medical information is then transmitted through the Internet for medical diagnosis and therapy. Classical Spirometry measures how effectively a patient's lungs function and requires supervision. We want to support impacted patients; thus, we built a monitoring system. With sensors including heartbeat, dust, temperature, and humidity, the device will collect health-related data and upload it to the cloud, helping doctors diagnose patients. This study uses private cloud computing to track and monitor real-time medical information in approved areas. In addition, the private cloud-based environment called a bounded telemonitoring system is meant to capture real-time medical details of patients in the medical centers inside and outside medical wards. In addition, a new wireless sensor network scenario is intended to monitor patients' health information 24/7. This research secures medical information access and guides future medical system development.
Russia and Japan as an Image of the “Other” on the Pages of British Periodicals of the Early 60s of the 19th Century
Authors: Gella Tamara
Published: October 2022

The article is devoted to the analysis of the socio-cultural perception of Russia and Japan as an image of the “other” in British society in the early 60s of the 19th century. Unlike previous studies of this problem, the source base was the publications of a number of British periodical journals. The choice of Russia and Japan as objects of study is due to the fact that both countries were perceived by English contemporaries as Asian countries with an Asian mentality of their population. However, Russia was also perceived as a Slavic country. In this regard, conducting a fragmentary cross-section of country studies within the framework of the British socio-cultural perception of Japan and Russia may be of interest both for understanding the relationship of Great Britain with these states, and for clarifying the Middle Victorian mentality as such. The article emphasizes that the criteria for the authors’ coverage of the events in Japan and Russia and the life of their peoples were different. With regard to Japan, the articles described not only its state system and the political situation in the country, but considerable attention was paid to Japanese nature, architecture, commerce, everyday life and culture of the Japanese. As for the Russian subjects, the materials were mainly devoted to the domestic and foreign policy of Russia since the beginning of the reign of Alexander II with a constant excursion into the history of the country. In this article, conclusions were drawn that British magazines, creating “Russian” and “Japanese” images, proceeded from the presence of the so-called “Japanese myth”, on the one hand, and on the other hand, from the prevailing stereotypical perception of the Russian people, thereby distorting the real picture of Russia and Japan in the early 60s of the 19th century.
Russian-British Interaction During the Disintegration of Yugoslavia In the Late 20th — Early 21st Centuries: the ABC of Bilateral and Multilateral Cooperation
Authors: Valeeva-Khakimova Rimma
Published: October 2022

The situation in modern international relations, the stalemate in diplomatic negotiations with the U.S. and NATO in early 2022, the refusal to recognize the legitimacy of Russia's demands for “red lines” for its security and respect for the conditions put forward by Russia, as well as disagreement with the position on the need to protect the residents of the DNR and LNR were some of the reasons for the launch of a special operation in Ukraine. Since the joining of Crimea to Russia in 2014, Britain has taken a tough stance and initiated economic sanctions against Moscow. With the start of the special operation in Ukraine, the United Kingdom announced sanctions, was the first to suspend air traffic with Russia, and decided to confiscate the property of Russian oligarchs living in Great Britain. Many British businesses, including Shell and BP, have suspended their operations in Russia. In these circumstances, it is more important than ever to review the history of cooperation between Moscow and London in resolving conflict situations and to analyze and identify the focal points on which effective cooperation was built in the past in order to find tools to improve cooperation between Britain and Russia in the future. This article examines the cooperation between the two countries in resolving the Croatian, Bosnian and Kosovo crises, analyzing the similarities and differences in approaches to these issues and the conceptual foundations of Moscow and London's interaction in international politics in general and in the resolution of these conflicts specifically.
Public Opinion of Russia and Latin America in Relation to the USA (Late 19th — Early 20th Centuries)
Authors: Ivanov Nikolai
Published: October 2022

The article analyses the formation of the ideology of anti-Americanism in Russia in the late 19th — early 20th centuries on the example of the heritage of famous Russian writers and publicists. Their works denounced the pragmatism, lack of spirituality, utilitarianism and pursuit of profit characteristic of Americans. The author argues with researchers who consider this criticism of the United States in Russia a unique phenomenon inherent only to the Russian people with their “innate xenophobia”. The most convincing argument is the comparison with the phenomenon of anti-Americanism in Latin America, where nations were created by European immigrants who, by definition, could not preach intolerance to foreigners. Nevertheless, in the public opinion of the continent by the end of the 19th — beginning of the 20th centuries, there was a persistent negative attitude towards the United States. It is very important that in the works of the main ideologists of anti-Americanism in Latin America (J. Martí, J. E. Rodó, R. Darío, A. Reyes etс.) we see the same rejection of North American pragmatism, utilitarianism, colonialism, expansionism and racism as in Russia.
“Russian Prestige” vs “Charm of the British”: Categories of Perception of Russian-British Rivalry in Qajar Iran
Authors: Larin Andrey
Published: October 2022

The article is devoted to the categories of description of the Russian-British rivalry in Qajar Iran in the Russian socio-political discourse of the 19th — early 20th century. Attention is focused on the use of such categories as “prestige”, “charm”, “dignity”, “Russian/British name” in different contexts of describing the competition of powers and making comparisons between them. Using a variety of materials, including diplomatic correspondence, reports, personal materials, press, it is shown that these concepts, although very abstract, played an important role in formulating the agenda and developing motivation for political decisions.
The Quiet Service of Maria Alekseevna Neklyudova (1866—1948)
Authors: Turygina Natalia
Published: October 2022

Maria Alekseevna Neklyudova (1866—1948) spent her whole life caring for girls: first, at the Patriotic Institute, then at the Smolny Institute for Noble Ladies, as well as the Odessa Women‘s Institute named after Emperor Nicholas I and finally at the Kharkiv Women‘s Institute, which she took out into exile and which she directed until its closure in 1932. Later she took care of the girls of the student dormitory in Belgrade, during the Second World War it gave shelter to yonger girls. Neklyudova took these girls from Serbia to Austria, however this step did not save them from repatriation to the Soviet Union. But even in exile in the village of Kuzkino of the Kuibyshev (Samara) region, she continued to take care of children, now looking after the children of a peasant in whose house she found shelter and where she lived until her death in 1948. Thus, she devoted her entire adult life to serving children and did not leave this work, in spite of all the difficulties. Neklyudova may not have been perfect, but she did her best to protect her maidens from the hardships and adversities of the reality surrounding them. In this paper, on the basis of the archival data, some milestones of Maria Alekseevna's life path, unknown in modern historiography, are restored. The materials of the periodical press and the memoirs of contemporaries help to understand what guided this woman in her sacrifice and indifference to other people's fate. The author tries to answer whether such a choice was her personal merit or was predetermined by the upbringing that she herself received within the walls of women's educational institutions for hereditary nobles in the Russian Empire.
