Published: March 2024

Abstract
This article presented micropolar hybrid nanofluid flow comprising copper and alumina nanoparticles over a flat sheet. The mixed convection phenomenon is studied under the effect of gravity. Some additional forces such as magnetic field, thermal radiation, Eckert number, heat source, and thermal slip condition are adopted in this analysis. The leading equations are transformed into dimensionless format by employing appropriate variables and then evaluated by homotopy analysis method (HAM). The obtained results are compared with published results and found a good agreement with those published results. Also, the results of HAM are compared with those of numerical method and found a good agreement as well. The fluctuations within the flow profiles are showcased utilizing figures and tables, followed by an in-depth discussion and analysis. The outcomes of this work show that the higher volume fractions of copper and alumina nanoparticles improved the hybrid nanofluid viscosity, which results in the augmenting variation in the velocity profiles. The higher volume fractions of copper and alumina nanoparticles improved the hybrid nanofluid thermal conductivity, which results in the augmenting variation in thermal distribution. The growing mixed convection factor amplifies the buoyancy force toward the stagnation point flow, which enlarges the velocity panel. The effects of hybrid nanoparticles (Cu-Al2O3/water) at the surface are smaller on friction force and larger in case of thermal flow rate when compared to the nanofluids (Cu/water and Al2O3/water).

Abstract
Xanthomicrol (4′,5-dihydroxy-6,7,8-trimethoxyflavone) is the main active component of Dracocephalum kotschyi Boiss leaf extract. It has showed selective cytotoxic activity against some cancer cell lines and little effect on human fetal foreskin fibroblast cells used as nonmalignant control. This study aimed to develop 99mTc-labeled xanthomicrol and to evaluate its efficiency as a new tumor imaging agent. l,l-Ethylene dicysteine (EC) chelator was conjugated to xanthomicrol. EC-Xanthomicrol was labeled with technetium-99m by using tin chloride as a reducing agent and incubating at room temperature. Radiochemical purity and in vitro stability were analyzed by thin layer chromatography and high-performance liquid chromatography. In vitro cellular uptake and binding profile of radio-conjugate was determined on C6 glioma cells. In vivo bioevaluation and imaging studies of [99mTc]Tc-EC-Xanthomicrol were performed in C6 glioma tumor induced rat at different time points after injection of radio-conjugate. The high radiochemical yield (>95 %) was achieved for [99mTc]Tc-EC-Xanthomicrol which was stable up to 6 h. The radio-conjugate indicated high cell uptake (35.12 % at 2 h) which demonstrated to be specific. Tumor uptake was seen for [99mTc]Tc-EC-Xanthomicrol (1.23 ± 0.14 %ID/g) at 1 h post injection. Scintigraphy confirmed that tumors could be visualized clearly with [99mTc]Tc-EC-Xanthomicrol. The results indicated that [99mTc]Tc-EC-Xanthomicrol has potential to be considered as a new radiotracer in glioma tumor imaging.

Abstract
Bio-derived materials could play a major role in future supportable green and health technologies. Nontraditional materials such as proteins and biopolymers are observed for their probable use in the fabrication of bioplastics for packaging. In the present work, novel ternary composite films of chitosan (CS), polyvinyl alcohol (PVA), with different ratios of natural egg white (EW) and glycerol as a plasticizer, were fabricated by solution casting technique. The synthesized ternary composite films were characterized by UV–Vis absorption spectra, Fourier transform-infrared spectroscopy (FT-IR), X-ray diffraction (XRD), and scanning electron microscopy (SEM) analysis. The hydrophobicity of as-synthesized samples was confirmed by contact angle measurement. The microbiological screening analysis was established against bacteria viz. Pseudomonas sp., Bacillus subtilis and Staphylococcus aureus bacteria. The attained results denoted that the film might be an appropriate applicant for food packaging applications.

Authors: Jin Yi , Xu Shengchao 
Published: March 2024

Abstract
In order to improve the detection and recognition capabilities of distributed multiband synthetic aperture radar (SAR) images in the Internet of Things environment, a distributed multiband SAR image fusion algorithm based on wavelet transform is proposed for the Internet of Things environment. The multispectral/hyperspectral imager is used to detect and process the distributed multiband SAR image. The feature extraction method of fast spatial geographic water target range radar signal source is used to extract and segment the distributed multiband SAR image. The wavelet multiscale transform method is used to segment the SAR image, and the linear filtering and nonlinear filtering methods are used to detect the edge contour features. Using the distributed multiband SAR image fusion technology based on the calculation of high-frequency subband edge function and the segmentation of regional gray contour curve, the splitting and broadening of the peak spectrum of the target image of the radar signal source in the fast spatial geographical waters, as well as the radar target positioning parameters, the noise filtering, and anti-jamming detection of the distributed multiband SAR image are realized, and the distributed multiband SAR image fusion is realized combined with wavelet transform. The test results show that the output peak signal-to-noise ratio of distributed multiband SAR image fusion using this method is high, and the performance of detection and recognition of SAR imaging targets and the ability of edge contour feature extraction are good.

Published: March 2024

Introduction. A comprehensive definition of culture encompasses shared norms, beliefs, expectations, language, and customs, all of which are crucial considerations when working with patients with limited English proficiency (LEP). In this study, the authors examined how language, external influences, and patient-provider relational factors associated with decisional conflict in prenatal care patients.
Methods. The authors conducted a cross-sectional study to assess decisional conflict related to postpartum contraception, elective induction, and newborn feeding methods. The survey included questions about demographics, communication methods, external influences, and provider trust, and was distributed to prenatal care patients who spoke either English or Spanish. Data analysis involved using descriptive statistics and chi-square analyses.
Results. Out of the 23 respondents, 12 were Spanish-speaking and 11 were English-speaking. Spanish-speaking participants were less likely to have health insurance compared to English-speaking participants (χ2(1, N = 23) = 3.67, p = 0.016). There was no statistically significant difference in decisional conflict between English- and Spanish-speaking participants. Religion affected 11 of 23 participants' decisions, while partner expectations influenced 10 of 23 participants. Working with an interpreter and the quality of interpretation were crucial for Spanish-speaking individuals. Most participants (59%) felt that the provider's understanding of the patient’s cultural background was important for decision-making.
Conclusions. While there was no association between language discordance and decisional conflict, several factors influencing prenatal decision-making were identified. The use and quality of interpretation significantly affected decision-making and should be prioritized for patients with LEP. Religion and partner expectations were found to be highly influential in decision-making. Respondents also emphasized the importance of the provider's understanding of the patient’s cultural background.

To compare the antimicrobial efficacy of NaOCl, QMix 2in1, Octenidine dihydrochloride, 940nm diode laser with and without NaOCl against matured E. faecalis biofilm.Ninety extracted single-rooted teeth were instrumented and autoclaved. The specimens were exposed to E. faecalis contamination over a period of 21 days and subsequently divided into six distinct groups through a random assignment process. Group I-Control, Group II-NaOCl, Group III-940nm Diode laser, Group IV-940nm Diode laser + NaOCl, Group V-QMix 2in1, Group VI-Octenidine Dihydrochloride. Microbial specimens were gathered, cultured, and the quantification of colony-forming units was conducted.ANOVA, Post hoc test, And Tuckey test were applied to find significance.940nm Diode laser +NaOCl group showed a greater antimicrobial effect compared to other groups. No significant difference was observed between 940nm Diode laser and 940nm diode laser +NaOCl (p=.550), NaOCl and QMix 2 in 1 (p=.121), NaOCl and 940nm Diode laser groups (p =.680)The concurrent use of both sodium hypochlorite and 940nm Diode laser light manifests a synergistic influence, enhancing the bactericidal efficacy. The antibacterial effect of QMix 2in1 is comparable to that of NaOCl, 940nm Diode laser, more effective than OCT and less effective than the combination of sodium hypochlorite and 940nm Diode laser.A combination of 940nm laser and NaOCl is effective in reducing the bacterial count because of their capacity to penetrate effectively deep into dentinal tubules, resulting in intensified bactericidal action compared to newer irrigants used alone.

Published: March 2024

The present study was designed to evaluate the role of herbal active constituent hydroxycitric acid obtained from Garcinia cambogia and Hibiscus subdariffa in heavy metal especially lead poisoning. The Lead acetate at 500ppm was used as an inducing agent in the present study. Sodium acetate (500ppm) used as control group is used as a baseline measure. The HCA at 100 mg/kg and 200mg/kg were used in the treatment of lead induced toxicity in rats. At the end of 28 days study period the blood levels of alpha ALAD activity was estimated in all the treatment groups. Lead inhibits the ALAD is more profound and its inhibition has been used clinically to gauge the degree of lead poisoning. Inhibition of ALAD results in the accumulation of aminolaevulinic acid, detectable in the plasma and urine even at blood lead levels of less than 10 µg/dl. It results that HCA showed significant elevated levels of ALAD activity, which was reduced by the lead intoxication. HCA showed significant reduction of liver enzymes (SGOT, SGPT and ALP). The markers like protein, bilirubin and creatinine were also found to be elevated in lead intoxicated rats and was found to be decreased significantly in a concentration dependent manner.

The lake’s image in the artistic worldview of the Northern text of Russian literature for children
Authors: Davydova A. V. 
Published: March 2024

INTRODUCTION. For the first time, the works of the Northern Text of Russian literature for children, in which the lake’s image arises, are systematized. The purpose of the study is to consider the artistic and semantic features of the leitmotif image of the lake in the context of the specifics of the artistic world of the North. The objectives of the research are to identify the main mythopoetic and realistic characteristics of the lake’s image in the works of the Northern text for children; to determine the motives and images with which it interacts as a structural element of the Northern text, to identify the place of the lake’s image in the artistic worldview of the North.MATERIALS AND METHODS. Using a systematic approach to the literary text, which is a set of methods (chronotopic, motivic, mythopoetic, systemic-semantic) that reveal the object as a single system, the lake’s image in the works of writers of the second half of the 20th century is considered: A. Linevsky, A. Petukhov, V. Pikul, M. Skorokhodov, A. Chlenov.RESULTS AND DISCUSSION. After analyzing the artistic material, it is concluded that there are two variants of the lake ’s image: tundra and forest lakes. The first is realized through the mythologeme of the circle and the personification method, the second through the motives of the two worlds, secrets, boundaries, changes of the hero. The lake’s image in the Northern text of Russian literature for children also approaches the images of the sea and the river and actualizes the motif of the unity of the world.CONCLUSION. This study is a particular stage in the study of the figurative-semantic structure of the Northern text of Russian literature for children as a supertext and indicates broad prospects for its further study.
Semantic differentiation in the linguistic examination of trademarks
Authors: Novichihina M. E. 
Published: March 2024

INTRODUCTION. The controversial issues of trademark examination are considered. The analysis of the ways of comparing single-word and compound commercial designations is given. A universal method for identifying a strong element in a composite designation has not yet been developed. The purpose of the study is to identify the semantic potential of non-identical concepts: a strong element and the main word in the phrase of a trademark or commercial designation.MATERIALS AND METHODS. Using a specific example from the experience of conducting linguistic examinations (comparison of the WHITE AURORA and AVRORA designations), the methodology for identifying a strong element of a composite designation is illustrated and the origins of typical errors in determining a strong element are analyzed. When developing the mentioned methodology, it is proposed to be guided by the following considerations: the concept of a strong element of designation and the main word of the corresponding phrase are concepts that are not common; the method of identifying a strong element in a phrase differs from the method of identifying the main word in a phrase; the phenomenon of a strong element correlates with the linguistic idea of a strong and weak lexical position in the text; a strong element can be located both in the first and second place in a phrase, including a trademark or other commercial designation.RESULTS AND DISCUSSION. It is shown that due to the semantic potential of a strong element of a composite designation, it becomes possible to transfer to the consumer the necessary information about the object of nomination. That is why the definition of an element bearing the main disti nguishing features must be carried out in the context of a situation or a communicative task. Based on the material of a specific example of linguistic expertise, it is shown that the element white of the designation WHITE AURORA in the context of the provision of dental services and dental care services can be interpreted as a strong element. This becomes a serious factor preventing the appearance of confusingly similar designations for WHITE AURORA on the one hand, and AVRORA on the other.CONCLUSION. Semantic differentiation is the main criterion for distinguishing strong and weak elements in the linguistic examination of trademarks. The very concept of a “strong element” of a designation can be considered a relative concept; the definition of an element bearing the main semantic features must be carried out in the context of a situation or a communicative task.
Promotion through sports: storytelling in telegram channels with sports focus
Authors: Prokhorov A. V. , Popov S. A. 
Published: March 2024

INTRODUCTION. In recent decade sport has been viewed as an independent industry. This circumstance contributes to the development of sports marketing concept. In a broad sense, sports marketing covers three main areas: “sports marketing” (sports products promotion activities), “marketing through sports” (marketing of non-sports brands) and “mass sports marketing” (pro-motion of healthy lifestyle ideas, physical activity). The article examines storytelling technology in the context of promoting goods and services in telegram channels with a sports focus. MATE-RIALS AND METHODS. The empirical basis of the research is formed by telegram channels of authoritative sports journalists S. Mikulik, V. Utkin, S. Gridasov (“Sergey Mikulik. While in memory ...”, “Real Radio Utkin”, “Gridasov with a beard”). The use of the content analysis method made it possible to identify authors’ types in analyzed telegram channels, as well as to characterize the features of storytelling use in the “packaging” of advertising integrations.RESULTS AND DISCUSSION. The conducted research allowed us to come to the following results: a) telegram channels with a sports focus have high potential in the “brand-audience” interaction; b) the main format for maintaining telegram channels is storytelling; c) storytelling is an effective way to “package” advertising integrations; d) the tone of storytelling is determined by the type of author of the telegram channel.CONCLUSION. Storytelling acts as a way to package advertising integrations, helps them achieve a native character, provides “channel tone” necessary for its author, and allows to form author’s style of a channel, which is manifested in the broadcast of the author’s types.
Newsjacking technology in advertising: the topic of sanctions and import substitution
Authors: Terskikh M. V. 
Published: March 2024

INTRODUCTION. Newsjacking is a fairly new media technology, which allows you to draw more attention to the promoted product and to ensure standing out from the competitors. Situational marketing of this type presupposes a focus of attention towards the newsworthy events and a high reaction rate to them. In the classic form, a newsworthy event rarely lives longer than five days, but there are also options for a prolonged newsworthy event, the appeal to which can be quite lengthy. COVID-19 became such a relevant “news stream” in 2020, and the topic of sanctions and import substitution in the period 2014–2016, 2022–2023 which is the subject of this study. The purpose of this study is to consider import substitution as the dominant of media discourse, which has become an urgent news reason and the basis of newsjacking technology.MATERIALS AND METHODS. The material for the study was more than 80 polycode advertising texts, which are based on an appeal to the discursive dominant “import substitution”. To achieve this goal, the following set of methods was used: directional sampling method; descriptive and analytical method; content analysis; discourse analysis; method of systematization and classification.RESULTS AND DISCUSSION. Analysis of representing the discursive dominant of “import substitution” in advertising texts allowed us to identifies the following basic techniques: use of stereotypical images associated with Russia; use of the symbols of the USSR; turn to the sanctions theme; direct replacement of foreign counterparts with Russian goods; adaptation of foreign brands.CONCLUSION. The use of the topic of import substitution in advertising is a very significant trend that many advertisers have used for a certain time, and in 2022–2023 this trend was updated in an updated version.
