Consumptive Behavior in Female University Students: Qana’ah and Hedonic Lifestyle as Predictors
Authors: Muawaliyah Wulan , Saifuddin Ahmad
Published: April 2023

Currently, many under graduate students are affected by consumptive behavior, so that consumptive behavior needs to be overcome, one of which is qana'ah behavior. Therefore, this study aimed to explain the correlation between qana'ah and a hedonic lifestyle with consumptive behavior in female students. The research method used was quantitative correlation study with a multiple regression analysis technique. There were three measuring tools used in this study, namely qana'ah scale, hedonic lifestyle scale, and consumptive behavior scale. Following a cluster random sampling approach, this study obtained a sample consisting 297 Universitas Islam Negeri (UIN) Raden Mas Said Surakarta female students aged 18-22 years old. The data analysis technique implemented in the present study was regression analysis resulting in F=151.488; R2=0.508; p<0.05. Partial analysis showed that qana'ah has a negative relationship with consumptive behavior, with a correlation coefficient of -6.415 (p <0.05), and hedonic lifestyle has a positive relationship with consumptive behavior, with a correlation coefficient of 13.570 (p <0.05). Qana’ah is negatively correlated with consumptive behavior, meaning that the higher the qana’ah level in oneself, the lower the prevalence of exhibiting consumptive behavior. Meanwhile, the hedonic lifestyle is found to be positively correlated with consumptive behavior. It means that when a person adopts a hedonic lifestyle, they are more likely to show consumptive behavior. Based on the analysis, there is a correlation between qana'ah and hedonic lifestyles with consumptive behavior in female students of UIN Raden Mas Said Surakarta. Thus, qana’ah can become a solution to reduce the level of consumptive behavior. In more serious cases, qana'ah can be made into therapy so that it becomes qana'ah therapy to reduce mental problems, one of which is consumptive behavior.

Support for Children’s Reading in Different Countries of the World. Review of the New Edition
Authors: Stolyarov Yury N.
Published: April 2023

One of the disturbing trends of our time is the decline in interest in reading all over the world, despite its obvious importance and irreplaceability. The reasons for this negative trend have not yet been fully investigated.

The presented review gives a high assessment of V.P. Chudinova’s book “Development of ‘Nations of Readersʼ in Different Countries of the World: Studies, Strategies, Projects, Practices” (2022). The publication contains the analysis of the situation with the support of childrenʼs reading in different countries of the world, as well as characterizes international programs of this profile. V.P. Chudinovaʼs work is based on the reliable materials of large-scale studies, including comparative ones that greatly increases the objectivity of the book. Much attention is paid to the support of childrenʼs and family reading by major international organizations: UNESCO, IFLA and the International Literacy Association. In separate chapters, the author considers promotion of reader literacy in the advanced countries of the world — Japan, Singapore, China and Great Britain. Along with the previously published textbook “Library and Information Services for Children and Youth Abroad” (2012), the new book by V.P. Chudinova has made a big step in highlighting the problem of supporting childrenʼs reading at the level of international organizations and the most successful countries in this regard. The considered subject may be linked to the “Sustainable Development Goals” adopted in 2015 by the UN General Assembly as a plan for achieving a better and more sustainable future for all.
The Category of Conscience in the Works of V.A. Mamchenko (By Foreign Publications)
Authors: Nosov Nikolay N.
Published: April 2023

The article is devoted to the work of the Russian poet of the first wave of emigration Viktor Andreyevich Mamchenko (1901—1982), reflected in his foreign publications in Russian. Returning the name of this author, now half-forgotten in his homeland, to culture and introducing him into literary circulation, the article is the first attempt to reveal the originality of V.A. Mamchenko’s creative thought, based on the poet’s religious, philosophical and moral searches. The object of the research is the foreign publications of V.A. Mamchenko’s artistic works in individual books and almanacs published in France and identified from the catalogs of leading Russian libraries (the Russian State Library, the Alexander Solzhenitsyn House of Russia Abroad). The memoires and reviews of V.A. Mamchenko’s contemporaries served as auxiliary material for the study. The article reveals the key milestones in the poet’s biography, which contributed to the formation of his creative style. There is traced the evolution of V.A. Mamchenko from the futuristic tendencies of the early period to the “high tongue-tie” and dissolution in the landscape of the middle and late periods of his creativity. There are identified the main moral-philosophical, God-seeking, religious and mystical categories, which were incorporated in the works of V.A. Mamchenko, who had been developing them for half a century. One of the key categories is conscience, which, according to V.A. Mamchenko, unites moral, philosophical and religious principles, permeating all the milestones of his work. Particular attention is paid to the individual works of V.A. Mamchenko — articles, poems, poetry cycles — as the most structured by the poet. Their chronological examination and comparison in the context of the main categories highlighted by the poet (hero, God, fear, death, conscience, awakening) allow to observe the vector nature of V.A. Mamchenko’s creativity, presented as an illustration of the soul’s path (the movement of the hero’s love) to God, where conscience acts as an accompanying inner core and compass.

Published: April 2023

Description of the subject. Weed pressure is a main biotic constraint in tropical agriculture. Cover crop mixtures have increased in popularity to limit weed growth through competition for resources, but the relationship between cover crop diversity and weed suppression is still under debate. Objectives. This study aimed to assess the impact of increasing cover crop diversity (one to four species) on weed control during two growing seasons (tropical summer and winter) in Reunion Island. Method. Weed control was expressed regarding ground cover by weeds and weed aboveground dry mass in the mixtures during four months of growth and its response to cover crop traits was tested using structural equation models. Results. While cover crops reduced weed ground cover and dry mass by 60% and 68% on average in summer and winter, respectively, a higher number of cover crop species within a mixture did not increase mean weed control. Nonetheless, weed control was influenced by the mixture composition and improved when including Guizotia abyssinica. Additionally, cover crop traits explaining weed control differed between growing seasons. In summer, weed control was mainly explained by the final cover crop aboveground biomass and leaf area (depletion strategy). In contrast, weed control was mainly explained by the cover crop rate of increase in ground cover (obstruction strategy) in winter. Conclusions. Using traits to characterize cover crop mixture enables us to identify mixtures of species and traits adapted to different growing conditions. Our study suggests that particular attention on species identity rather than diversity should be paid in mixture to improve weed control in tropical conditions.

Published: April 2023

We introduce a new carbazole-based zwitterionic ligand (DCzGPC) synthesized via Yamaguchi esterification which enhances the efficiency of lead halide perovskite (LHP) nanocrystals (NCs) in light emitting diodes (LED). A facile ligand exchange of the native ligand shell, monitored by nuclear magnetic resonance (NMR), ultraviolet-visible (UV-vis), and photoluminescence (PL) spectroscopy, enables more stable and efficient LHP NCs. The improved stability is demonstrated in solution and solid-state LEDs, where the NCs exhibit prolonged luminescence lifetimes and improved luminance, respectively. These results represent a promising strategy to enhance the stability of LHP NCs and to tune their optoelectronic properties for further application in LEDs or solar cells.
Slip distribution of the February 6, 2023 Mw 7.8 and Mw 7.6, Kahramanmaraş, Turkey earthquake sequence in the East Anatolian Fault Zone

Published: April 2023

On February 6, 2023, two large earthquakes occurred near the Turkish town of Kahramanmaraş. The moment magnitude (Mw) 7.8 mainshock ruptured a 310 km-long segment of the left-lateral East Anatolian Fault, propagating through multiple releasing step-overs. The Mw 7.6 aftershock involved nearby left-lateral strike-slip faults of the East Anatolian Fault Zone, causing a 150 km-long rupture. We use remote-sensing observations to constrain the spatial distribution of coseismic slip for these two events and the February 20 Mw 6.4 aftershock near Antakya. Pixel tracking of optical and synthetic aperture radar data of the Sentinel-2 and Sentinel-1 satellites, respectively, provide near-field surface displacements. High-rate Global Navigation Satellite System data constrain each event separately. Coseismic slip extends from the surface to about 15 km depth with a shallow slip deficit. Most aftershocks cluster at major fault bends, surround the regions of high coseismic slip, or extend outward of the ruptured faults. For the mainshock, rupture propagation stopped southward at the diffuse termination of the East Anatolian fault and tapered off northward into the Pütürge segment, some 20 km south of the 2020 Mw 6.8 Elaziğ earthquake, highlighting a potential seismic gap. These events underscore the high seismic potential of immature fault systems.
Best Proximity Point Results in Fuzzy Normed Spaces
Authors: Sabri Raghad Ibrahaim , Ahmed Buthainah Abd Al Hassan
Published: April 2023

Fixed point (briefly FP ) theory is a potent tool for resolving several actual problems since many problems may be simplified to the FP problem. The idea of Banach contraction mapping is a foundational theorem in FP theory. This idea has wide applications in several fields; hence, it has been developed in numerous ways. Nevertheless, all of these results are reliant on the existence and uniqueness of a FP on some suitable space. Because the FP problem could not have a solution in the case of nonself-mappings, the idea of the best proximity point (briefly Bpp) is offered to approach the best solution. This paper investigates the existence and uniqueness of the Bpp of nonself-mappings in fuzzy normed space(briefly FN space) to arrive at the best solution. Following the introduction of the definition of the Bpp, the existence, and uniqueness of the Bpp are shown in a FN space for diverse fuzzy proximal contractions such as ?????? fuzzy proximal contractive mapping and ????h ????h - fuzzy proximal contractive mapping.
Personal Identity of Senior Pupils in Connection with Their Cognitive Motives
Authors: Zuiev Ihor , Beliaeva Karina , Milanina Anastasiia
Published: April 2023

The aim of the work is to study the personal identity of senior pupils in connection with their cognitive motives. Identity is considered an awareness of self-identity, integrity, and continuity of a person. The development of personal identity is understood as a process of constant awareness of one’s uniqueness, authenticity, and originality. It was empirically found that in senior pupils with low levels of cognitive motives, the reflexive “self” and the physical “self” prevail, and in pupils with high levels of cognitive motives, physical and active “selves” prevail. “Pseudoidentity” as a status prevails among the respondents. For the pupils with a low level of cognitive motive, a “diffuse identity” is typical, and for those with a high level of cognitive motive, a “moratorium” is typical, i.e., an identity crisis, which is accompanied by a desire to actively solve life’s challenges, determine themselves and use various behaviors for those purposes. It has been found that in pupils with a low level of cognitive motive, the formation of an active “self” is connected with the “premature identity”, and in those with a high level - with the “gained (genuine) identity”. The cognitive motive may be a positive factor in developing self-identity in senior pupils.

Os tumores de tireoide representam 4% das neoplasias em cães, sendo os carcinomas mais comuns, correspondendo a 88% dos tumores da tireoide. Estes são caracterizados por seu rápido crescimento e invasividade. Devido a isso, o presente trabalho objetiva relatar um caso de carcinoma subtipo folicular compacto de tireoide em um canino, com ênfase em seus aspectos clínicos, diagnósticos e terapêuticos. Foi atendido um canino macho, castrado, sem raça definida, com sete anos, pesando 27 kg com queixa de dispneia há 60 dias, perda de peso, disfonia e aumento de volume em topografia de glândula tireoide. Foi realizado citologia por agulha fina guiada por ultrassonografia com diagnóstico sugestivo de um carcinoma de tireoide. Após, foi solicitada tomografia computadorizada para planejamento cirúrgico. Como tratamento optou-se pelo uso de fosfato de toceranib, 3,25 mg.kg-1, três vezes na semana, associado ao piroxicam 0,3 mg.kg-1, uma vez ao dia, durante 60 dias, no qual apresentou redução do tamanho da massa e sinais clínicos, com isso, o paciente passou por ressecção cirúrgica e encaminhado fragmento tecidual para análise histopatológica que confirmou o diagnóstico de carcinoma subtipo folicular compacto. No pós-operatório, paciente apresentou piora no quadro clínico e apesar do manejo intensivo, evoluiu para o óbito. Neoplasias de tireoide apresentam comportamento biológico agressivo e baixa sobrevida, sendo a terapia adjuvante com o fosfato de toceranib eficiente na diminuição da massa neoplásica. Ainda, o exame citológico encontra-se como uma ferramenta crucial de triagem para condução diagnóstica, no entanto, o diagnóstico definitivo só pode ser realizado pela análise histopatológica.

Epistemologi “Anything Goes” Paul Fayerabend Relevansinya dalam Pengembangan Pengetahuan.
Authors: Wibawa Nazar Husain Hadi Pranata
Published: April 2023

This article seeks to demonstrate the applicability of Paul Feyerabend's "anything goes" epistemology to the development of knowledge. This study is a literature review. Data were collected through data inventory, then analyzed and interpreted. The results of the study show that "all methodologies have limitations, and the only 'rule' that can survive is 'anything goes'". The main idea of anything goes is, first, the recommendation proposed by Feyerabend related to the discourse of anything goes, only remains as a negative freeing recommendation because it requires a certain scientific situation that is considered to restrict scientists; and is often understood simply as advocating the absence of laws, methodologies, and rules in science. Second, it actually limits the movement of scientists because it requires participation only in practices that are undefined and cannot be defined. Third, it is only a consequence of the first and second premises. In other words, anything goes, both externally and internally, contains two dimensions of freedom at once. The differences in position must be clarified to avoid confusion about the status of freedom contained in anything goes.
SGT: Session-based Recommendation with GRU and Transformer
Authors: Wu Lingmei , Zhang Liqiang , Zhang Xing , Jiang Linli , Wu Chunmei
Published: April 2023

Session-based recommendation aims to predict user preferences based on anonymous behavior sequences. Recent research on session-based recommendation systems has mainly focused on utilizing attention mechanisms on sequential patterns, which has achieved significant results. However, most existing studies only consider individual items in a session and do not extract information from continuous items, which can easily lead to the loss of information on item transition relationships. Therefore, this paper proposes a session-based recommendation algorithm (SGT) based on Gated Recurrent Unit (GRU) and Transformer, which captures user interests by learning continuous items in the current session and utilizes all item transitions on sessions in a more refined way. By combining short-term sessions and long-term behavior, user dynamic preferences are captured. Extensive experiments were conducted on three session-based recommendation datasets, and compared to the baseline methods, both the recall rate Recall@20 and the mean reciprocal rank MRR@20 of the SGT algorithm were improved, demonstrating the effectiveness of the SGT method.

Analytical Study on the Effect of Electric Arc Furnace Dust (EAFD) on the Rutting of Asphalt Concrete Mixtures
Authors: A.T. Alsheyab Mohammad , S. Khedaywi Taisir
Published: April 2023

As a byproduct of the steelmaking process, significant amounts of hazardous electric arc furnace dust (EAFD) are produced. Utilizing the solidification/stabilization technology with asphalt mix is one way to safeguard the environment from its negative effects. Rutting was used as an indicator to assess the asphalt mixture with EAFD since it is an important factor in pavement design. This study's major goal is to ascertain how EAFD affects the rutting of asphalt-concrete mixtures. To evaluate the ideal asphalt content, the Marshall test method was applied to asphalt concrete mixtures. EAFD was added to the asphalt cement in four different volume percentages as a binder addition. Then, using the Universal Testing Machine, participants were exposed to a replica of the rutting test (UTM). Experiments were conducted at 25, 40 and 55oC, and at frequencies of 1, 4 and 8 Hz. Rutting was measured for each specimen. Tests results showed that while rut depth has negative correlation with of EAFD% and positive correlation with the temperature. The use of EAFD has dual advantages, protecting the environment from the adverse impact of EAFD and reducing the cost of asphalt mix without jeopardizing the pavement performance.

Published: April 2023

The midwife's working posture when taking the placenta attached to the uterus of the laboring mother manually shows the body's posture which can cause musculoskeletal disorders. This research aims to know and study the assessment of the REBA method for midwife workers' posture in the prevention of musculoskeletal disorders. This research method is a type of observational analytic study that uses descriptive qualitative in total sampling among midwife workers. Data was collected using a REBA sheet. The results showed the results of the assessment using REBA with a final score of 13 has a level of risk "Very High" and requires immediate corrective action. This risk is caused by the back being bent and twisting laterally, the midwife's neck twisting laterally, the upper arm of the worker experiencing flexion, and the position of the arm is raised away from the body due to the position of the uterus being far and narrow. Suggestions given are efforts to control engineering, the provision of work procedures, and the procurement of healthy safety work.

Published: April 2023

The addition of Nigella sativa and Gracilaria verrucosa to feed is used as a supplement to increase non-specific immunity in tilapia. The addition of herbal supplements is safe for consumption, easy to decompose, has no residue on the fish's body, and does not harm the environment. This study aims to find the effectiveness of the addition of the herbs Nigella sativa and Gracilaria verrucosa to increase non-specific immunity in tilapia. The study used an experimental method with a completely randomized design, applying 4 treatments and 1 control to tilapia. The dietary doses of Nigella sativa were T0 (control, without Nigella sativa), T1 (2.5), T2 (5), T3 (7.5), and T4 (10) (g kg-1 feed). While the dietary doses of Gracilaria verrucosa were T0 (control, without G. verrucosa), T1 (0.5), T2 (1), T3 (1.5), and T4 (2) (g kg-1 feed). The results showed that the percentage of hematocrite increased significantly with the Nigella sativa diet, while on the Gracilaria verrucosa diet, the percentage of hematocrit was not significant. Further, the Nigella sativa diet and the Gracilaria verrucosa diet can significantly increase the percentage of lymphocytes, but not significantly to the percentage of monocytes. In fish farming, the Nigella sativa and Gracilaria verrucosa diets have the potential to be used to increase non-specific immunity in tilapia, but it is more effective to use the Nigella sativa diet at a dose of 5 g kg-1 feed.

Pada tahun 2019 terdapat 16 desa di Kabupaten Banyumas yang termasuk daerah endemik DBD diantaranya Kelurahan Mersi dan Desa Ledug. Pengendalian vektor tetap merupakan metode yang paling efektif untuk pencegahan dan pengendalian DBD karena belum ada terapi antivirus yang spesifik dan vaksin dengue yang efektif. Sebelum dilakukan pengendalian DBD, diperlukan data mengenai populasi nyamuk Aedes aegypti di suatu daerah. Salah satu metode untuk mengetahui kepadatan populasi nyamuk di suatu daerah yaitu dengan survei ovitrap. Penelitian ini bertujuan untuk mensurvei kepadatan populasi nyamuk Aedes aegypti menggunakan ovitrap di Kelurahan Mersi dan Desa Ledug. Penelitian ini merupakan penelitian deskriptif dengan pendekatan cross sectional. Survei ovitrap dilakukan dengan cara meletakkan sebanyak 100 ovitrap di dalam rumah dan luar rumah. Ovitrap di ambil pada hari ke 10 kemudian dikumpulkan larva Aedes aegypti dan dihitung menggunakan Ovitrap Index (OI). Hasil penelitian menunjukkan bahwa rata-rata Ovitrap Index (OI) di Kelurahan Mersi yang berada di dalam rumah lebih rendah yaitu 14% dibandingkan yang di letakkan di luar rumah sebanyak 24,4%. Begitu juga dengan Desa Ledug jumlah populasi nyamuk larva Aedes aegypti yang dihitung menggunakan Ovitrap Index (OI) di dalam rumah lebih rendah yaitu sebanyak 46% dibandingkan luar rumah sebanyak 56%. Hal ini dapat dikatakan kepadatan populasi nyamuk yang sedang di Kelurahan Mersi dan tinggi di Desa Ledug.

Introducción. El trasplante simultáneo de riñón y páncreas es reconocido como un tratamiento eficaz para el manejo de pacientes con diabetes mellitus, principalmente de tipo I, e insuficiencia renal crónica. Sin embargo, hoy en día aún existe dificultad para el seguimiento del injerto pancreático, ya que no existe un marcador serológico definitivo que lo permita y persiste la dificultad para la toma de biopsias. Se ha descrito una modificación en la técnica quirúrgica que permitiría el acceso endoscópico mediante una duodenoduodenostomía.

Materiales y métodos. Se seleccionaron los pacientes que recibieron un trasplante simultáneo de riñón y páncreas con derivación exocrina al duodeno, evaluando la seguridad del procedimiento, la evolución y las complicaciones médico-quirúrgicas.

Resultados. Nueve pacientes fueron sometidos a trasplante simultáneo de riñón y páncreas con derivación exocrina al duodeno. La mediana de la edad fue de 36 años y la mayoría era del sexo masculino. El tiempo de isquemia en frío fue de 10 horas para el injerto pancreático y de 11 horas para el renal. El tiempo total de hospitalización fue de 21 días. Se presentó una pérdida del injerto pancreático y una pérdida del injerto renal. Hubo una sola muerte, causada por aspergilosis pulmonar.

Conclusiones. La derivación exocrina duodenal permite y facilita la evaluación y el seguimiento endoscópico del injerto pancreático. No supone una mayor exigencia técnica en el trasplante simultáneo de riñón y páncreas, ni un incremento en el número de complicaciones en relación directa con la modificación del procedimiento quirúrgico

La cirugía oncológica se desarrolló como una rama de la cirugía general, que busca facilitar la interacción entre la radioterapia, la oncología médica y las demás especialidades, para concertar un plan terapéutico integral y multidisciplinario del paciente con cáncer. En este artículo se presenta una revisión narrativa de los principios básicos del abordaje diagnóstico y terapéutico del paciente oncológico, bien sea con un diagnóstico inicial o recurrente. Se hace particular énfasis en la necesidad de plantear un tratamiento curativo de ser posible, con márgenes claros y con una aproximación quirúrgica que tenga en cuenta el comportamiento y la diseminación tumoral. Cuando la curación no sea posible, en el contexto de un tratamiento multimodal, la cirugía paliativa es una opción válida y acertada. Los principios de la cirugía oncológica deben ser interiorizados y respetados por todos los cirujanos que enfrentan y tratan pacientes con cáncer. La observancia de estos principios garantizará mejores resultados para los pacientes. “En el mundo de la cirugía oncológica, la biología es rey, la selección de casos, la reina, las técnicas quirúrgicas y maniobras son los príncipes y princesas. Ocasionalmente, el príncipe y la princesa tratan de usurpar el trono; casi siempre fallan en derrocar las poderosas fuerzas del rey y la reina”. Blake Cady

Introducción. En el trasplante renal con HLA idéntico los episodios de rechazo agudo son menores y tienen mejores tasas de supervivencia del injerto, comparado con los receptores con HLA no idéntico; a pesar de esto, persiste el dilema en cuanto al retiro o la disminución de la dosis de inmunosupresión. El objetivo de este trabajo es describir la experiencia de los trasplantes renales con HLA idéntico de donante vivo y cadavérico que se han realizado en la Fundación Valle del Lili desde 1995 hasta 2014.

Material y métodos. De los 1.462 trasplantes renales realizados se incluyeron aquellos con HLA idéntico. Se hizo un análisis estadístico descriptivo para todas las variables consideradas y, para subgrupos seleccionados, el análisis de supervivencia y de rechazo agudo se hizo con el método de Kaplan-Meier. Para el análisis se usó Stata 12.0®.

Resultados. Se practicaron 29 trasplantes renales con HLA idénticos. La mayoría fueron en hombres de raza mestiza y lo más frecuente fue una etiología desconocida de la enfermedad renal terminal. Dos pacientes presentaron rechazo agudo, y la supervivencia de los injertos a 1, 5, 10 y 15 años, fue de 100%, 93,7 %, 75 % y 75 %, respectivamente; la supervivencia de los pacientes a los 1, 5, 10 y 15 años, fue de 100%, 93,7 %, 84,3 % y 84,3 %, respectivamente.

Conclusiones. Losreceptores HLA idénticos poseen una supervivencia prolongada del injerto con menos tasas de rechazo agudo.

Los tumores seudopapilares sólidos del páncreas representan del 1 al 2 % de las lesiones neoplásicas del páncreas exocrino. Descritos por primera vez por Frantz, han recibido múltiples denominaciones hasta su clasificación actual por la Organización Mundial de la Salud (OMS). Carecen de un cuadro clínico típico y frecuentemente se diagnostican de manera incidental por estudios de imágenes de sección transversal, en los que se reconocen características clave para su diagnóstico, y se presentan especialmente en mujeres jóvenes y adolescentes. Actualmente, su tratamiento es fundamentalmente quirúrgico, prefiriéndose técnicas conservadoras, con excelentes resultados a largo plazo. Se reporta el caso de una mujer joven con síntomas abdominales inespecíficos, a quien después de tratamientos previos para otras posibles enfermedades, se le practicó una tomografía computarizada de abdomen en la cual se documentó una lesión de características típicas de este tipo de tumor; fue sometida a pancreatectomía distal y esplenectomía laparoscópicas, con confirmación histológica de la neoplasia y sin necesidad de tratamiento adicional posterior

Published: April 2023

Heat exchanger is an important device in the industry for cooling or heating process. To increase the efficiency of heat exchanger, nanofluids are used to enhance the convective heat . transfer relative to the base fluid. - Al2O3/water nanofluid is used as cold stream in the shell and double concentric tube heat exchanger counter current to the hot stream basis oil. These nanoparticles were of particle size of 40 nm and it was mixed with a base fluid (water) at volumeconcentrations of 0.002% and 0.004%. The results showed that each of Nusselt number and overall heat transfer coefficient increased as nanofluid concentrations increased. The pressure drop of nanofluid increased slightly than the base fluid because of the low concentration used.

Published: April 2023

This paper describes the application of consensus optimization for Wireless Sensor Network (WSN) system. Consensus algorithm is usually conducted within a certain number of iterations for a given graph topology. Nevertheless, the best Number of Iterations (NOI) to reach consensus is varied in accordance with any change in number of nodes or other parameters of . graph topology. As a result, a time consuming trial and error procedure will necessary be appliedto obtain best NOI. The implementation of an intellig ent optimization can effectively help to get the optimal NOI. The performance of the consensus algorithm has considerably been improved by the inclusion of Particle Swarm Optimization (PSO). As a case study, variable number of nodes in a network with a random graph topology has been considered. Simulation results show that significant reduction in the NOI and power consumption has been achieved, where it decreased the NOI about 40 iteration; when using PSO for different number of nodes in the specified network.
African Perspective of the Ukrainian Crisis: Assessments and Actions from China
Authors:   Institute for African Studies RAS, Fituni Olga
Published: April 2023

The article is devoted to the assessment by the PRC analytical community of the impact of the Ukrainian crisis on the development of African countries, China-Africa relations and relations between Beijing and Western countries. The overall official position of the Chinese authorities regarding the crisis was detailed in a document distributed at the end of February 2023 entitled “China’s position on the political settlement of the Ukrainian crisis.” The publications of Chinese scientists and analysts concerning the African perspective of the problem, which were published mainly before the advent of the Government paper, dealt almost exclusively with aspects of the influence of the Special Military Operation on the intensification of the food crisis, the disruption of global value chains and the debt problem. They dealt with a fairly wide range of technical issues, but in the overwhelming majority they did not reveal the deep foundations and initial prerequisites for the problems that had arisen. At the same time they closely resonated with Western objectivist approaches to these issues.
