COMPARISON OF METHODS OF NON-MECHANICAL PRESSURE MEASUREMENT IN THE CUFF OF AN ENDOTRACHEAL TUBE
Authors: SADOVY V.YU
Published: October 2024

Background: Tracheal injuries are uncommon but pose significant risks in anesthesiology and critical care. These injuries primarily occur due to the direct mechanical impact, often linked to the excessive pressure from the intubation tube's cuff. This study aims to assess the actual cuff pressure in intubated patients during surgeries, examine how these measurements correlate with anesthesiologists' subjective evaluations, and compare various cuff inflation techniques.
Methods: The study included 90 patients, divided into two groups of 45 each. For the experimental group, the cuff was inflated using the «minimum leakage» method, while the control group used palpation to gauge the required pressure. The actual cuff pressure for both groups was determined using a mechanical manometer connected to the cuff.
Results: The mean pressure in the experimental group was 30.4 ± 4.9 cm H2 O (2.98 ± 0.48 kPa), significantly lower than the control group's 68.9 ± 23.3 cm H2 O (6.75 ± 2.28 kPa). In the control group, only 2 patients were within the safe pressure range, compared to 23 in the experimental group.
Conclusion: The palpation method for estimating cuff pressure in intubated patients often does not reflect the actual pressure values. The study highlights the effectiveness of the minimal occlusion volume technique as a non-mechanical method for more accurately measuring and controlling cuff pressure.

Photoredox-Catalyzed Activation of C(sp3)–H Acids and Total Synthesis of Hyperolactone C
Authors: Barriault Louis , Morris Avery , O'Brien Tegan
Published: October 2024

We present a detailed study on photoredox catalysis platforms that directly engage 1,3-dicarbonyl C(sp3)–H acids towards radical reactions. This platform enables redox-neutral hydroalkylation and cross-coupling, as well as oxidative transformations that demonstrably improve on the prior state of the art. Interrogations of the underlying catalytic cycle and mechanism for this platform through kinetic, thermodynamic, and computational studies enabled the 4-step synthesis of the spirocyclic natural product hyperolactone C and unnatural analogues. The present investigations also demonstrate the key role of lithium trifluoroacetate under complementary Ce-containing and Ce-free photoredox conditions to enable ligand to metal charge transfer (LMCT) or multi-site proton coupled electron transfer (MS-PCET) activations, respectively.
Thermally immobilized cellulose acetate butyrate on silica particles as stationary phase for high-performance liquid chromatography
Authors: Ambroso Isabela , Silva Aline , Santos Allyson , Assunção Rosana , Faria Anizio
Published: October 2024

Reversed-phase liquid chromatography is the most widely used analytical technique nowadays. However, it generates a large volume of toxic organic residues and presents poor separations of small polar molecules in traditional stationary phases. In this work, cellulose acetate butyrate was synthesized and used as a reversed-phase coating for separating compounds using highly aqueous mobile phases, reducing organic solvent consumption and minimizing the supra-cited problems. Cellulose acetate butyrate presented a degree of substitution of 0.65 (±0.05) by 1H nuclear magnetic resonance, resulting in hydrophilic and hydrophobic groups in the polymer. The stationary phases were characterized physicochemically by infrared spectroscopy, indicating the polymer attachment on the silica surface with 180 m2 g-1 of surface area and 22 nm of mean pore size. The stationary phase was column-packed and chromatographically characterized by separating the Tanaka mixtures. These separations occurred in reversed-phase mode with hydrophobic and hydrophilic interactions related to the acetate/butyrate and hydroxyl groups from cellulose derivative. The stationary phase showed unique selectivity for separating small polar molecules with 90 % water in mobile phases. Cellulose acetate butyrate stationary phase can potentially separate polar compounds requiring high water contents, making reversed-phase liquid chromatography closer to the Principles of Green Chemistry.
Electronic Absorption and Circular Dichroism Spectra of One-Dimensional Bay-Substituted Chiral PDIs: Effects of Intermolecular Interactions, Vibronic Coupling and Aggregate Size
Authors: Xu Yuchuan , Zhao Yi , Liang Wanzhen
Published: October 2024

Electronic circular dichroism (ECD) spectroscopy is the preferred tool for studying organic chiral supramolecules. However, it is a great challenge to experimentally clarify the contributions to ECD spectra from molecular vibrational motions and the intermolecular interactions, key factors for an efficient system architecture design of chemical sensors, catalysts or optoelectronics. Focusing on this issue, here, we per- form theoretical studies on the vibrationally resolved absorption and ECD spectra of two one dimensional bay-substituted chiral perylene diimides (PDIs) by employing the non-Markovian stochastic Schr¨odinger equation with respect to the model Hamiltonian in the diabatic representation, which includes the intramolecular local- ized excited states (LEs), inter molecular change-transfer excited states (CTEs) and the vibronic couplings (VC) as well. Our calculated results exhibit that the theoretical spectra with inclusion of VC effect agree better with the experimental ones than those without this effect, and that the difference between the traditional absorption spectra of two bay-substituted PDIs is much less obvious than that in their ECD spectra, veri- fied that ECD spectroscopy is sensitive to the absolute configuration and conformation of chiral supramolecules. We further make a comparison among the pure electronic spectra of aggregates with different aggregate size calculated by the time-dependent density functional theory, and the mixed exciton model with and without decoupling the LE and CTE states. It is shown that the hybridization between LE and CTE states results in the emergence of new peaks or trough in the high-energy band, and a significant deviation between the calculated ECD spectrum and that predicted by the exciton chirality rule. It is further shown that the ECD spectra of oligomers exhibit an odd-even alternation pattern with changes in aggregate size.

Therefore, it is essential to systematically grasp the themes, frontiers, and trends of research in this field, organizing the knowledge system to provide references for future studies. This necessitates clarifying the research achievements of scholars from different disciplines and institutions. Using the CiteSpace visualization analysis method, we can analyze, summarize, and synthesize research networks, hotspots, and knowledge structures, thereby forming a direction for advancing research. Through literature review methods and knowledge graph software analysis, it is believed that value rationality and instrumental rationality represent the rational attitudes individuals adopt when contemplating issues and putting them into practice. They are merely methods and should not be subjected to excessive value judgments. The relationship between value rationality and instrumental rationality is a focal point of societal concern, involving complex interdisciplinary issues with significant theoretical value and practical implications. In the future, the academic community needs to strengthen research collaboration, enhance the expansion of value rationality in various social practice fields, and conduct empirical studies to build consensus for the construction of Chinese society.

Published: October 2024

Background: Pediculus humanus capitis (head lice) infestation is a global health concern, yet no study has examined its occurrence among primary school children in Tunisia. Aim: To assess the prevalence of Pediculus capitis and its epidemiological characteristics among primary school children living in rural and urban areas of Monastir, Tunisia. Methods: We used 2-step stratified cluster sampling to randomly select 2396 children from 14 primary schools in Monastir during the 2022/2023 academic year. Head lice infestation was assessed through visual inspection of the hair, and data on the socio-demographic characteristics, lifestyle and pediculosis history of the children were collected. We used SPSS version 20 to analyse the data and used descriptive statistics to rate the frequencies. Multivariate logistic regression was used to examine the association between pediculosis and the predictor variables. Results: Overall infestation rate was 17.5% (95% CI 16.0–19.1%); infestation was 5 times higher among girls (29.1%) than boys (6.3%). Schoolchildren living in crowded family households, those in the third and fourth grades and whose parents had low education level were more exposed to infestation. Combing frequency, comb sharing and history of previous infestation had significant impact (P < 0.05) on the prevalence of pediculosis. Multivariate logistic regression showed gender and treatment outcome as the main potentiating factors. Conclusion: These findings highlight the need for pediculosis prevention and integrated health promotion programmes among primary school children and their parents, teachers and nurses in Monastir and other parts of Tunisia.

Authors: Usman Abdurrahman Hi. , Mahmud Adi F.
Published: October 2024

The primary aim of this study was to address the challenges of low speaking proficiency and motivation among second-year students in an Islamic education university department. This was achieved by implementing an integrated teaching strategy within a Classroom Action Research (CAR) framework to enhance students' speaking skills and active involvement in the learning process. The study employed a CAR design, conducted over two cycles. Each cycle comprised four stages: planning, action, observation, and reflection. The intervention involved an integrated teaching strategy that combined multiple language skills—listening, speaking, reading, and writing—within a cohesive instructional framework. Data were collected through post-tests, observation checklists, and reflection notes. Quantitative data were analyzed using descriptive statistics and paired sample t-tests, while qualitative data were examined through thematic analysis. The results demonstrated significant improvements in both speaking performance and student engagement between Cycle 1 and Cycle 2. In Cycle 1, the majority of students scored in the "Fair" category, with only 24.39% achieving "Good" scores. Following strategic adjustments, Cycle 2 saw a marked increase in average post-test scores, with 87.80% of students meeting or exceeding the success criteria. The level of active involvement also rose significantly, reflecting the effectiveness of the revised integrated strategy. The findings highlight the value of integrated language instruction and the importance of iterative refinement in teaching methodologies. This study contributes to the theoretical understanding of language acquisition and offers practical insights for EFL educators, particularly in contexts where students face challenges in developing speaking proficiency. The study underscores the need for creating supportive and engaging learning environments that foster student participation and language development.This study provides empirical evidence supporting the effectiveness of integrated teaching strategies in EFL contexts, particularly within Islamic education settings. It demonstrates how Classroom Action Research can be utilized to improve teaching practices and student outcomes continuously. The research offers a model that can be adapted and applied in similar educational contexts to enhance language learning.

Published: October 2024

For aviation binders at the moment there is no necessary methodological base on the basis of which it is possible to control the conditions of their curing by viscosity, reaction rate and glass transition temperature in real time. The paper presents a method of control of thermosetting binder parameters directly during the molding process. The epoxy binder VSE-59 was studied. A mathematical model of the relationship between the frequency maximum parameter of the imaginary component of the electrical impedance and the degree of curing is given, the results of dielectric analysis are compared with laboratory methods (differential scanning calorimetry and rheometry). It is shown that the convergence of the values of the degree of conversion is high. Rheological and dielectric analyses revealed a direct correlation between electrical and rheological properties in the range of injection temperatures. Equations were determined and coefficients were experimentally selected to describe the correlation between viscosity and glass transition temperature and dielectric parameters, which provides the possibility of their control in real time. The obtained results can be used to create a hardware and software base, which makes it possible to control the state of the binder at each moment of the process of forming products from polymer composite materials, as well as to carry out optimization to eliminate the emergence of conditions of uneven polymerization. Realization of the detailed control of the binder state in different parts of the product will allow to carry out verification of calculations, to predict and avoid the occurrence of warping and, accordingly, to increase the quality of composite products.
Eliminating the «memory effect» during mass spectrometric determination of mercury
Authors: Shchukin V. M. , Kuz’mina N. E. , Erina A. A. , Bunyatyan N. D.
Published: October 2024

When estimating mercury content by inductively coupled plasma mass spectrometry (ICP-MS), this element adsorbs on the surface of the sample introduction system of the instrument, which creates problems in the determination of trace amounts of mercury. Various methods of cleaning the instrument have been proposed in the literature. Objective: to experimentally compare the effectiveness of trace mercury removal methods proposed in the literature for elemental analysis by ICP-MS and to select the optimal cleaning agent. Methods: Mercury content in solution was determined by the Agilent Technologies 7900 inductively coupled plasma mass spectrometer using 202Hg isotope. Diluted solutions of nitric and hydrochloric acids, solutions of gold chloride, potassium dichromate, thiourea, L-cysteine, potassium bromide, potassium bromate of different concentrations in water and 1% nitric and hydrochloric acids, aqueous solution of ammonium pyrrolidinedithiocarbomate were used as washing agents. Results: The background level of mercury content is achieved by using solutions of copper chloride (5%), thiourea (0.01, 0.1, and 0.5%), L-cysteine (2%), potassium bromide and bromate (0.0005 M) in 1.0% hydrochloric acid solution. The background is lowered by using 3 and 5% HCl, potassium dichromate (60 mg/liter), potassium bromide and bromate (0.01 and 0.05 M) solutions in 1% hydrochloric acid. Application of aqueous solution of ammonium pyrrolidinedithiocarbamate causes sharp degradation of plastic tubes of the sample introduction system. Conclusion: The efficiency of washing agents based on hydrochloric acid is higher than that based on nitric acid and water. The most promising washing agents are bromide-containing solutions and potassium bichromate solution in hydrochloric acid. The optimal way to clean the device is its washing with 0.5 mM potassium bromide solution in 1.0% hydrochloric acid. Its use allows to reduce the background content of mercury and does not complicate the analysis of the content of other elements.
Intensified cleaning of parts immersed in a detergent solution
Authors:   Timirâzevskaâ selʹskohozâjstvennaâ akademiâ, Korneev N.V.
Published: October 2024

The quality of cleaning metal parts from contaminants depends on the physical and chemical properties of the washing medium and the intensity of the mechanical impact of the liquid on the surfaces subject to cleaning. Intensified cleaning of the parts is possible when there is an unsteady mode of a washing liquid flow, characterized by change of pressure and speed of a liquid in time and in each considered point of a surface subject to cleaning. In order to confirm the theoretical statement about the dependence of cleaning efficiency on the speed of the washing liquid flow, the authors made an experiment. They took a combined submerged washing machine using a combination of two hydromechanical methods of cleaning intensification. The parts subject to cleaning moved in the bath by means of the platform vibration. A helical blower provided the turbulent flow of the washing liquid relative to the object subject to cleaning. The authors used connecting rods of internal combustion engines as the objects to be cleaned. Their surfaces contained asphalt-resin contaminants, which were hard to remove. The cleaning process was studied in the aqueous solution of detergent Temp-100D with a concentration of 20 g/l at a temperature of 65 to 70°C. The cleaning lasted for 15 min. The quality of cleaning from contaminants was controlled by wettability of the cleaned surface with water. It was found that the intensity of cleaning, characterized by the liquid flow rate necessary for the detachment of dirt particles, depends on the vibration frequency of the platform holding the cleaned parts. Increasing the vibration frequency from 0.25 to 1.0 Hz leads to a three-fold increase in the flow rate of the cleaning solution, which provides an intensive removal of contaminants while increasing the quality of cleaning. When increasing the vibration frequency from 0 to 1.0 Hz, the cleaning efficiency increases in 2.5 times. The study results confirmed the theoretical supposition of the relationship between the cleaning efficiency and the washing liquid flow rate.
Electric ozonizer-air emitter for agricultural buildings: study results for an autonomous module
Authors:   Timirâzevskaâ selʹskohozâjstvennaâ akademiâ, Storchevoy V.F. 
Published: October 2024

The air environment of livestock buildings requires disinfection and improvement of the gas composition. The most effective method is ozonation. In order to improve the air inside livestock buildings, the authors have developed an electric ozonizer-emitter. Its emitter module consists of two ceramic bases with different-potential tungsten electrodes, one base having an electrode in the form of a honeycomb cell, and the other - in the form of a rod. The ozone productivity is regulated by changing the discharge gap between the emitter electrodes and the conducting plane. It has been theoretically established that ozone formation in a corona discharge depends on the electric field strength between the different-potential electrodes and their heating temperature. In this case, the maximum strength is achieved with a discharge gap from 25 to 35 mm and electrodes with a radius of no more than 2 mm. The effect of electrode heating temperature on ozone formation was studied on the developed design of the ozonizer-emitter in a laboratory of 180 m3 at an air temperature of 25°C above zero. The air gap between the electrodes was 30 mm, the voltage on the emitter varied from 10 to 30 kV, the duration of the ozonizer-emitter operation ranged between 0 and 80 min, the airflow rate induced by the electric fan was 0.3 m/s. It was experimentally established that stable operation of the ozonizer-emitter is observed when the electrode temperature does not exceed 30°C. In the future, the authors plan to introduce the ozonizer-air emitter into the ventilation and air conditioning system of agricultural buildings.
Gender stereotypes: essence, types and influence on self-realization of women of different ages

The article provides a detailed examination of the concept and essence of gender stereotypes, their
diversity. The specific features of the impact of gender stereotypes on women’s self-realization in early and middle
adulthood were analyzed. It has been found that gender stereotypes are fixed beliefs (ideas) about what women/
men are like and should be like, which shape their behavior in society.
The problem of the gender stereotypes is considered by the authors as one of the most crucial and relevant in modern
society due to a predominantly negative impact on women’s self-realization, which is reflected in complications
in career advancement of women, existence of gender-based occupational segregation in the labor market,
discrimination as well as conformism, personal stagnation, rigidity, devaluation of personality.
The study has demonstrated that most of the women recognize the existence of gender stereotypes in modern
society and aware of their impact on self-realization. Masculinity-Femininity stereotypes are predominant among
the other types of gender stereotypes in both young and middle-aged women.
The empirical examination has revealed that stereotypical beliefs are inherent in married women to a greater
extent compared to single women. A comparative analysis has shown that women in early adulthood are less
likely to manifest stereotypical beliefs than women in middle adulthood. Moreover, it was found that women
in early adulthood have a higher level of striving for self-actualization compared to middle-aged women.
Respondents have low scores on the “Spontaneity”, “Autosympathy”, and “Human Nature” scales, and high scores
on the “Values” and “Creativity” scales. The following tendency can be observed: the women with a high level
of stereotyping have lower index of self-realization than the women with non-stereotypical views.
Despite numerous scientific works of foreign and national scientists about gender stereotypes, the problem
of the impact of gender stereotypes on women’s self-realization has not been studied in depth by Ukrainian
scientists. This highlights the relevance and novelty of the scientific work.
Using digital technologies for the development of children with autism
Authors: Kornya P.
Published: October 2024

The article is devoted to the directions of using digital technologies for the development of children
with autism. The importance of digital technologies in the education and development of children with autism
spectrum disorders (ASD) has been studied. Five areas of technology in which software is developed for children
with ASD are analyzed, such as: mobile technology, robotics, virtual reality, augmented reality and mixed reality.
It was determined that the use of certain technologies should be conditioned by the requirements that different
categories of autistic children may have. Examples of five areas of application of digital technology tools aimed
at intervention, correction or training are offered. The proposed tools of digital technologies differ in that they do
not simply correct or develop certain skills in children with ASD, but rely on their existing personal characteristics,
which will ensure the effective use of these technologies.
The analysis of scientific literature made it possible to conclude that a psychological and pedagogical feature
of teaching children with autism is the need to take into account their specific needs and abilities of students.
The main features are the need to develop social and communication skills, among which the development
of social interaction skills with peers is very important. At the level of theoretical generalization, it was determined
that the use of ICT for teaching children with autism allows you to use current developments in the field of IT and
improve the processes of socialization of a child with special needs, his social skills and, in particular, the skills
of interacting with peers.It was determined that it is appropriate to use innovative methods that use such learning
technologies as computer technologies designed for PCs, mobile and communication devices (smartphones,
tablets, etc.) with appropriate software applications, robots, augmented, virtual or mixed reality technologies
and others that will help children with autism learn and develop social interaction skills.
Model of innovative personality: structural and dynamic approach
Authors: Zhelanova V.
Published: October 2024

The relevance of the presented article is determined by the globalization and European integration
transformations of modern society, in which innovation becomes an essential feature of all its spheres, which
objectively determines the necessity and expediency of innovative reformation of higher education, as one
of the basic social institutions, which is the surface of formation of an innovative personality. The purpose
of the article is to develop a model of an innovative personality based on the positions of the structural-dynamic
approach. The tasks consist in the definition and analysis of thorough theoretical positions, the essence and
structure of the innovative personality, the dynamics of certain components and their presentation in the form
of a model. The initial basic phenomena of the article are analysed, which are: “innovations”, “model”. A scientific
thesaurus of the problem of the subject of innovation is given, represented by such concepts as: “innovator”,
“innovative personality”, “innovative type personality”, “innovatively oriented personality”. The etymology
of the concept of “innovative personality” is revealed. The concepts in which this concept appeared for the first
time were analysed, namely: the theory of social changes, the concept of polar dichotomies (sociology
of changes). An overview of studies that consider the problem of an innovative personality from an aspect
is presented. The model of an innovative personality is represented, which contains innovative orientation (a set
of motives, needs, values, attitudes), innovative-cognitive (synthesis of innovative knowledge, cognitive style,
cognitive activity), innovative-praxeological (complex of innovative skills and innovative behaviour), reflexiveprognostic
components (innovative and reflective qualities and innovative potential). It was concluded that
an innovative personality is a product and subject of the modern information society. It is fundamentally different
from the personality syndromes of pre-informational civilizations and is the main resource for the success
of modern society.
