Published: December 2023

A study of the air behavior in the near-wake region of the NACA0012 airfoil infinite wing model at low Reynolds numbers was conducted. The study consisted of comparing the results obtained from experiments with those from numerical simulations. The numerical results of the velocity profiles in the near-wake region showed good agreement with those provided by the PIV system for most of the simulations and those in the literature. In addition, boundary layer separation and reattachment forming a laminar separation bubble along the airfoil was captured using simulations in Ansys Fluent and compared with a literature database to better confirm the simulation results. The UAVs have a complex cross-section shape of the fuselage. The second part of this paper explores the aerodynamic consequences of its shape, at the operational flight ceiling, in a comparative approach for three different fuselage designs.

Evaluation of Cytotoxicity of 1H-1,2,4-Triazole-3-carboxamide Derivatives in Various Cancer Cell Lines using MTT Assay: Synthesis, Characterization and Molecular Docking Studies
Authors: Sharma Dipesh Kumar , Singh Surabhi
Published: December 2023

The pursuit of discovering efficacious novel anticancer agents is an ongoing and perpetual endeavour. The ongoing research endeavour involves the discovery of a new set of various substituted 1,2,4-triazole carboxamide derivatives. The synthetic process involves multiple steps: converting thiooxamic acid ethyl ester to ethyl b-N-boc-oxalamidrazone (2), preparing ethyl esters of 5-substituted 1,2,4-triazole-3-carboxylic acid (3) and synthesizing 5-substituted 1,2,4-triazole-3-carboxylic acid amides (4a-n) using potassium tert.-butoxide. The resulting compounds are characterized using 1H and 13C NMR spectroscopy and HRMS. Molecula  docking experiments were performed using the synthesized compounds against two cancer targets, viz. EGFR (6LUD) and CDK-4 (7SJ3). The compounds were assessed for their anticancer potential against four different cancer cell lines, namely non-small cell lung cancer (A-549), pancreatic cancer (PANC-1), colorectal cancer (HCT-116) and cervical cancer (HaLa) cell lines. Additionally, a normal human embryonic kidney cell line (HEK-293) was used for comparison. The results obtained from molecular docking analysis demonstrated that the 1,2,4-triazole carboxamides (4c, 4e, 4h, 4m and 4n) exhibited more favourable binding interactions compared to the ligands that were co-crystallized. All the compounds exhibited a satisfactory cytotoxicity profile in comparison to the reference drug doxorubicin. Among the compounds that tested, it was observed that compounds 4e and 4m displayed the most pronounced inhibitory activity across all the cell lines that were tested.

Authors: Jangra Arti , Kumar Ramesh , Kumar Jai , Singh Jaiveer
Published: December 2023

The present study reports the synthesis of humic acid-modified magnetite nanoparticles for adsorption behaviour towards the ofloxacin drug. Several analytical and spectroscopic techniques were used to characterize the synthesized surface modified magnetite nanoparticles. In order to determine the highest possible adsorption capacity of these coated nanoparticles, the effects of various influencing variables such as pH of the solution, contact time, initial concentration of adsorbate solution, amount of adsorbent and temperature were also investigated using batch adsorption method. Adsorption isotherm and kinetic analysis for the adsorption of ofloxacin drug from aqueous solution were studied simultaneously. The kinetics and isotherm studies demonstrated good agreement with the pseudo-second-order kinetics model and Langmuir model of isotherm, respectively. Thermodynamic analysis of the adsorption of ofloxacin on the surface of humic acid modified magnetite nanoparticles displayed negative values of Gibb’s free energy change, positive values of enthalpy as well as entropy change, resulting that the adsorption process was spontaneous and endothermic in nature. A comparative study of percentage drug removal efficiency of humic acid functionalized magnetite nanoparticles with the reported adsorbents has also been reported. This study revealed that the humic acid-modified magnetite nanoparticles showed remarkable adsorption capacity and thus could be used as an effective adsorbent for the removal of ofloxacin from aqueous solution.
Investigation of Parameters Influencing the Activity and Selectivity of Ru-Sn Catalyst for Chemoselective Hydrogenation of Benzoic Acid to Benzyl Alcohol
Authors: Shinde Sunil B. , Deshpande Raj M.
Published: December 2023

This study assessed the Ru-Sn catalyst’s performance in benzoic acid hydrogenation to benzyl alcohol, highlighting the optimal Sn/Ruratio of 5 for peak activity in a Ru-Sn/Al2O3 system. TiO2 support outperformed Al2O3 and SiO2, achieving a 72% conversion rate and 83% selectivity towards benzyl alcohol. Increasing the reduction temperature enhanced catalyst activity and selectivity. While Ru remained stable, tin showed leaching; this decreased with reuse of catalyst and higher catalyst reduction temperatures. Notably, TiO2 support minimized Sn leaching and benzoic acid’s acidity did not induce Sn leaching. The findings provide key insights into optimizing the Ru-Sn catalyst for hydrogenation of benzoic acid.

Published: December 2023

The requirements of sustainability and the green chemistry principles have prompted organic chemistry researchers to come up with novel methods for the synthesis of organic compounds that require minimum energy consumption and pose lesser environment harm. Ultrasonication of reaction mixtures is one such methodology. High frequency sound waves are known to emit energy that is utilized in product generation. Attempts were made to synthesize 2-pyridone derivatives using ultrasonication assisted method of synthesizing 3-cyano-pyridine-2(1H)-one starting from a three component one pot reaction. The reaction between cyanoacetamide, aromatic ketones and substituted aromatic aldehydes in the presence of NaOH as base yielded 4,6-diaryl-2-oxo-1,2-dihydropyridine-3-carbonitrile derivatives as a result of one-pot multicomponent reaction. The synthesized 4,6-diaryl-2-oxo-1,2-dihydropyridine-3-carbonitrile derivatives were characterized by 1H NMR, 13C NMR, HRMS and FTIR spectra. Ultrasonication has been found to significantly reduce reaction time, enhance reaction rate and yield compared to conventional heating methods.

Published: December 2023

Cytokinins (CTKs) are a diverse collection of evolutionarily conserved adenine‐derived signaling molecules classically studied as phytohormones; however, their roles and production have been less studied in mammalian systems. Skeletal muscles are sensitive to cellular cues such as inflammation and in response, alter their secretome to regulate the muscle stem cell and myofiber niche. Using cultured C2C12 muscle cells, we profiled CTK levels to understand (1) whether CTKs are part of the muscle secretome and (2) whether CTKs are responsive to cellular stress. To induce cellular stress, C2C12 myotubes were treated with lipopolysaccharides (LPS) for 24 h and then media and cell fractions were collected for ultra high‐performance liquid chromatography tandem mass spectrometry with electrospray ionization (UHPLC‐(ESI+)‐HRMS/MS) for metabolomics and CTK profiling. Across LPS‐treated and control cells, 11 CTKs were detected in the extracellular space while 6 were detected intracellularly. We found that muscle cells are enriched in isopentenyladenine (iP) species (from free base, riboside to nucleotide forms), and that extracellular levels are increased after LPS treatment. Our study establishes that muscle cells express various forms of CTKs, and that CTK levels are responsive to LPS‐induced cell stress, suggesting a role for CTKs in intra‐ and extracellular signaling of mammalian cells.

Published: December 2023

Though it is well known that mammalian cardiomyocytes exit cell cycle soon after birth, the mechanisms that regulate proliferation remain to be fully elucidated. Recent studies reported that cardiomyocytes undergo dedifferentiation before proliferation, indicating the importance of dedifferentiation in cardiomyocyte proliferation. Since Runx1 is expressed in dedifferentiated cardiomyocytes, Runx1 is widely used as a dedifferentiation marker of cardiomyocytes; however, little is known about the role of Runx1 in the proliferation of cardiomyocytes. The purpose of this study was to clarify the functional significance of Runx1 in cardiomyocyte proliferation. qRT‐PCR analysis and immunoblot analysis demonstrated that Runx1 expression was upregulated in neonatal rat cardiomyocytes when cultured in the presence of FBS. Similarly, STAT3 was activated in the presence of FBS. Interestingly, knockdown of STAT3 significantly decreased Runx1 expression, indicating Runx1 is regulated by STAT3. We next investigated the effect of Runx1 on proliferation. Immunofluorescence microscopic analysis using an anti‐Ki‐67 antibody revealed that knockdown of Runx1 decreased the ratio of proliferating cardiomyocytes. Conversely, Runx1 overexpression using adenovirus vector induced cardiomyocyte proliferation in the absence of FBS. Finally, RNA‐sequencing analysis revealed that Runx1 overexpression induced upregulation of cardiac fetal genes and downregulation of genes associated with fatty acid oxidation. Collectively, Runx1 is regulated by STAT3 and induces cardiomyocyte proliferation by juvenilizing cardiomyocytes.
Electro-chemo-mechanical properties of anodic oxide (passive) films formed on Cu, Ni and Fe
Authors: Seo Masahiro
Published: December 2023

Electro-chemo-mechanical properties of anodic oxide (passive) films formed on metals have been reviewed focusing on the results of stress variations caused by anodic oxidation of Cu, Ni, and Fe thin film electrodes in deaerated pH 8.4 borate buffer solution at 25 °C. The surface stress varies toward compressive direction due to adsorption of OH on Cu from aqueous solution as well as adsorption of oxygen on metals from gas phase. The stresses are generated with the growth of three-dimensional anodic oxide films on metals. The magnitude and sign (tensile or compressive) of the intrinsic film stress were determined by taking the residual stress of the substrate and the dielectrostriction into consideration. The tensile or compressive intrinsic film stress depends on p-type or n-type semiconductive properties of the anodic oxide films, which is explained in terms of the void formation or oxide formation in the metal side at the metal/film interface. Furthermore, the stress variation toward compressive direction during cathodic reduction of the anodic oxide films is explained in terms of the volume expansion due to the formation of intermediate species.

Published: December 2023

In this study, rice husk was the precursor for a KOH-activated carbon with high surface area and high micro-porosity. CO2 adsorption capacity of this material was measured by thermogravimetric analysis. The CO2 adsorption kinetic showed that equilibrium was reached 30 min after the solid-gas phases came into contact and is well-described by the pseudo-first order model (R
2 > 0.99 and 95 % confidence level). Intraparticle diffusion model revealed multilinearity over the CO2 adsorption range. Isotherm data at 25, 35, and 45 °C were well-fitted by the Freundlich model, revealing the adsorbent’s surface heterogeneity and the exothermic behavior of the process. The material reached a maximum CO2 adsorption capacity of 2.54 mmol/g. A comparison with literature data showed a good agreement.

Published: December 2023

In order to better solve the shortcomings of the k-means clustering method and density peaks clustering (DPC) method in agricultural image segmentation, this work proposes a method to divide points in a high-dimensional space, and a clustering method is obtained to divide crops and soil. In the process of assigning points in the DPC method, if a point is divided incorrectly, a series of points may be assigned to a cluster that is not related to it. In response to this problem, this study uses the decision graph to select the centroids, and uses Gaussian kernel to map the data to the high-dimensional space, each centroid searches for the most relevant points in the high-dimensional space until a temporary boundary point is found to stop the first assignment strategy, and then the points that are not clustered are assigned to the correct cluster to complete the clustering. The experimental results show that the proposed method has a better clustering effect through experiments on multiple artificial datasets and UCI datasets, compared with other clustering methods, and finally applied to plant image segmentation.

Published: December 2023

Radiative thermal management technologies that utilize thermal radiation from nano/microstructure for cooling and heating have gained significant attention in sustainable energy research. Passive radiative cooling and solar heating operate continuously, which may lead to additional heating or cooling energy consumption due to undesired cooling or heating during cold nighttime/winters or hot daytime/summers. To overcome the limitation, recent studies have focused on developing radiative thermal management technologies that can toggle radiative cooling on and off or possess switchable dual cooling and heating modes to realize sustainable and efficient thermal management. This review will explore the fundamental concepts of radiative thermal management and its switching mechanisms, utilizing novel systems composed of various materials and nano/microstructures. Additionally, we will delve into the potential future research directions in radiative thermal management technologies.

Published: December 2023

Abstract. The research focuses on addressing the challenges of evaluating the effectiveness of modern power systems in countries with different configurations. Given the growing interest of con-sumers in the impact on the electricity supply schedule, the research is divided into two main parts. Firstly, a model has been developed to assess the operational efficiency of the power system. Secondly, a method for analyzing the efficiency of the energy system has been developed, based on a model of changes in energy system quality indicators. The presented model takes into account energy system characteristics such as the probability of network failure, normalized frequency of electricity, and the volume of consumed and supplied electrical energy. It is expected that this model will provide a more accurate assessment of the efficiency of the energy system under normal operating conditions. Additionally, a method for analyzing the operational efficiency of the energy system has been developed, based on a model of changes in energy system quality indicators. The uniqueness of this method lies in the introduction of a new comprehensive indicator of energy system efficiency, deter-mined by the convolution method of partial indicators, namely: the volume of electricity supply, supply quali-ty, and electricity supply efficiency. The reliability of the model is confirmed by calculations of the daily schedule of supply and load. Keywords: electric power system, electricity supply efficiency, evaluation of power supply system effi-ciency, electricity indicators, load schedule, consumer management, electricity supply quality.

Published: December 2023

La política es un escenario interesante para análisis de los comportamientos sociales. Casi 80 años después del sufrágio universal, aún existen barreras para la apropiación del espacio público por las mujeres. Para mejor entendimiento: las mujeres como sujeto pasivo de la política y las mujeres como sujeto activo de la política. La estética femocrática aqui surge como una categoria analítica y una propuesta teórica para poder analizar y comprender el fenómeno de las políticas y la interseccionalidad del género. Como metodología, utilizaremos algunas acciones políticas realizadas por el gobierno Bolsonaro con enfasis en dos mujeres importantes de su gobierno: Michelle Bolsonaro y Damares Alves. Como resultados tenemos un modelo de gobierno neoliberal con estética femocrática (negativa), lo que caracteriza algunas de las democracias del siglo XXI gobernadas por los movimientos de ultraderecha o extrema derecha.

Published: December 2023

Mortar beams incorporating carbon nanofibers (CNFs), which were synthesized in situ on Portland cement particles, were used to produce nanomodified Portland cement sensors (SmartCem sensors). SmartCem sensors exhibited an electrical response comparable to a thermistor with a temperature coefficient of resistivity of − 0.0152/ °C. The highest temperature sensing was obtained for the SmartCem sensor, which contained ~ 0.271 wt.% of CNFs. The calculated temperature sensitivity was approximately 11.76% higher in comparison with the mortar beam containing only unmodified Portland cement. SmartCem sensors were used to monitor the cement hydration in large-scale self-compacting concrete beams. The measurements were conducted after casting for 7 days. Additionally, commercially available thermocouple and humidity sensors were used as references. The results showed that changes in electrical resistivity measured by the SmartCem sensor were well aligned with the ongoing hydration processes.
‘Just the Way it Was’- Perspectives on Sexual Harassment in Medical School and #MeToo of Women Graduating Prior to 1975
Authors: Walling Anne , Gillam Morgan , Nilsen Kari
Published: December 2023

Introduction.The purpose of this study was to assess gender-based mistreatment during medical education recalled by women who attended medical school between 1948 and 1975 and their perspectives on the #MeToo movement.
Methods. Qualitative analysis of video-recorded structured interviews.
Results.The 37 participants graduated in classes of 2-20% women. They described pervasive, multi-faceted gender-based mistreatment during training. Twenty (54%) disclosed personal experience of serious sexual mistreatment. Interviewees stressed that attitudes and behaviors toward women and trainees, now regarded as unacceptable, were previously widely accepted or tolerated. The majority (86%) expressed overall positive opinions of their training. Twenty-eight (76%) supported the #MeToo movement, four (11%) had negative opinions, and five (13.5%) were ambivalent or unwilling to comment. Seventeen (46%) were concerned that #MeToo damaged working relationships, twelve (32%) were concerned about overreach, and eight (22%) about false accusations.
Conclusions.This group of older female physicians reported extensive experience of gender-based mistreatment and strong support of #MeToo. Nevertheless, about one quarter of the group did not support the #MeToo movement and even supporters expressed high rates of concern about the movement going too far, falsely accusing men of inappropriate behavior, and damaging working relationships. The interviewees did not want their medical training to be characterized as entirely negative, or to be portrayed as victims.

We present the case of a 45-year-old man with no prior medical or surgical history who presented to our hospital's emergency department with abdominal pain, vomiting, inability to pass gas, and no bowel movements. Physical examination revealed abdominal distention and tenderness. His white blood cell count was 10.9 x 10^3/µl, and hemoglobin levels were 13.3 g/dl.
Neolexemes with the Component Media in Dictionaries and Scientific Discourse on Social Communications
Authors:   Odesа Polytechnic National University, Balandina Nadiya
Published: December 2023

The article analyzes the array of innovative lexis which includes the component media and comprises 425 units from the perspective of mediadeterminism. The lexemes have been chosen using the Ukrainian lexicographic sources, the academic papers in the field of social communications and medialinguistics and also the monitoring of the Ukrainian Internet sector conducted during the period of January-March, 2023. The neolexemes with the component media have been proven to be an open dynamic system replenished constantly under the influence of technologies and socio-communicative transformations. This was confirmed by the monitoring of their description in the Ukrainian etymological and specialized dictionaries starting from 1973. The dynamics of the entry of neologisms as the terms into the academic discourse is traced on the example of two numbers of special publications on social communications for 2010 and 2022. The study has revealed the increase in frequency of using the terms with the component media, the heterogeneity of their fixation as neographisms, the living process of synonymization of the lexemes mass media and media, as well as the tendency for autochthonization of the indeclinable word form media. The paper shows the way for the further systemizing of the collected array of lexical units and its representation as a qualitative-quantitative hierarchic structure that contains the nominations of media space with its technical, technological, and socio-communicative components as the reference points. The most verbalized areas of the media space can serve as the indicators of media social spheres. The accumulated database of neolexemes with the component media can prove to be useful for lexicographic purposes.

Authors:   Taras Shevchenko National University of Kyiv, Ukraine, Marynenko Iryna
Published: December 2023

The article is devoted to classification and analysis of lexical-semantic deviations from language norms in the materials of the UNIAN news tape. Considering the dramatic events in our country over the past year and a half, the citizens consume much more actively the information products, from which they gain knowledge of the Ukrainian language, striving to improve it in this way. However, not all journalists conscientiously fulfill their professional duty, assuming various deviations in their texts, including lexical and semantic ones. The objective of this study was to identify the erroneous lexical norms in media texts and to draw attention of authors‘ journalistic materials to them. It was determined that all collected abnormal cases are primarily divided into intentional deviations, consciously used by the journalists in the texts and unintentional deviations, caused by low professional competence of their authors. Among the intentional deviations, there are often inappropriately used emotionally expressive and stylistically marked lexemes, such as colloquial, slang, swearing and vulgar words. Purposeful use of such language units aims to attract attention to the publications, which cannot be justified based on the requirements for language style of informational texts. Unintentional deviations include semantically modified lexemes; tautologies and pleonasms; confusion of the meanings of paronyms and cross-language homonyms; interferems and Russianisms as evidence of professional carelessness and inattention to the created materials. A significant amount of materials collected during the month testifies to the improper attitude of journalists of this news agency to their professional duties. After all, it is news texts that today belong to the most widely read, from where citizens replenish their vocabulary and learn the rules of using words and their combinations. Eliminating the listed problems will make it possible to improve the language competence of both the journalists themselves and the readers of their materials.

Published: December 2023

The objective of the article was to determine the semantic dominants of text headlines on tourism topics, written by the students of ESIJ (Educational and Scientific Institute of Journalism) and published on OTIUMPORTAL website – a specialized information resource that positions itself as a creative workshop where the future journalists improve their skills and abilities. The task of the authors was to select the concepts, development of which demonstrated the semantic accents of headlines in their estimative and communicative characteristics, as well as to consider the linguistic means of different levels, due to which the semantic accent was manifested. When working with the material, the following methods were applied: the continuous sampling method, which allowed to select the titles according to ―validity of information‖ parameter, the methods of analysis and synthesis, the conceptual analysis, which contributed to identify the semantic dominants and to determine the role of semantic actualizers in the textual space, and also to enable the classification and the generalization of the obtained results. The descriptive method was applied to present the research to the scientific community. The selected research object (627 article headlines) was examined from the point of view of content and form. The analysis was carried out taking into account three levels of the headline text: 1) the semantic level, which presents an understanding of the semantic level of the sentence, the goal-setting of this mini text, interaction with presupposition; 2) the estimative level, in which the subjective (evaluative) principle is the most evident, and 3) the communicative level, which demonstrates the reader‘s encouragement to communicate. The main results of the research are: determination of the headlines‘ semantic dominants in interaction of meanings of the concepts ―journey‖, ―topos‖, ―emotions‖, highlighting the ways of semantic deployment of these concepts through definitions, granularity, precedent text, identification of forms of implementation of communicative intentions.

Nonsteroidal anti-inflammatory medicines, collectively referred to as NSAIDs in academic context, exhibit chemical diversity while concurrently manifesting comparable therapeutic and harmful effects. All pharmaceutical substances under this particular category function by diminishing inflammation, alleviating pain, and reducing fever by means of inhibiting enzymes responsible for the creation of endoperoxides, often referred to as cyclooxygenase (COX) enzymes. The two cyclooxygenase isozymes, COX-1 and COX-2, are responsible for the conversion of arachidonic acid into its endoperoxide metabolites. These metabolites include prostacyclin, prostaglandins, and thromboxane, each exhibiting a wide range of biological activities such as inflammation, regulation of smooth muscle tone, and promotion of thrombosis. The COX-1 enzyme is consistently produced and is recognized as the main provider of prostanoids required for maintaining physiological balance, such as safeguarding the stomach epithelium. In contrast, the COX-2 enzyme is capable of being induced, leading to a substantial increase in the synthesis of prostanoids in circumstances characterized by stress and inflammation. Nonsteroidal anti-inflammatory drugs (NSAIDs) may induce toxicity via the same pharmacological mechanisms that contribute to their therapeutic efficacy. This review aims to discuss NSAIDs toxicity in details, its symptoms, and possible management in the emergency room.
Seagrass as a Bioindicator for Heavy Metal Pollution in Semi-Enclosed Marine Ecosystems

Published: December 2023

This study delves into utilizing Seagrass as a bioindicator for heavy metal detection in semi-enclosed marine ecosystems, with a specific focus on the Jordanian coast of the Gulf of Aqaba. The research evaluates the relationship between human activities and the responses of marine organisms, employing the seagrass species Halophila stipulacea as a key subject. This research examines the ability of seagrass to sense and respond to environmental changes, particularly in terms of trace metal accumulation. These accumulations serve as indicators of the marine environment's health and the extent of human impact. Observations revealed differences in trace metal concentrations across three distinct habitats. Notably, varying levels of Cadmium (Cd) and Chromium (Cr) were found in seagrass leaves, while Copper (Cu) and Iron (Fe) were more prevalent in roots. Increased concentrations of Malondialdehyde (MDA), a marker of environmental stress as indicated by lipid peroxidation (LPO), point to a potential link between human activities, such as boating, and the health of seagrass. These findings underscore the complex interactions between marine biology, environmental management, and the innate abilities of organisms to perceive and adapt to changes in their environment. The study bridges the gap in understanding organismal responses to environmental changes and emphasizes the need for ongoing research. Such research is crucial to comprehend the broader effects of environmental shifts on marine life. By continuously monitoring trace metal levels and understanding the responses of seagrass over time, this study lays the groundwork for innovative conservation and management strategies. These strategies are aimed at protecting vital marine environments from the growing impacts of human disturbances.
