Published: October 2024

To restore comfort, function, and esthetics while maintaining occlusal stability, restoring a single missing anterior tooth in a periodontally impaired dentition is a significant task. An implant-supported crown, traditional three-unit fixed partial denture (FPD), cantilever FPD, resin-bonded FPD, or removable partial denture can be considered in a normal, healthy dentition; however, problems with mobility and poor periodontal support of the remaining dentition may make these procedures unfeasible options as it might be difficult to avoid overloading of the implant in periodontal compromised adjacent teeth, difficult to achieve proper esthetics with conventional FPD, to maintain the stability of dental arch with acrylic resin removable partial dentures is not possible and incidences of frequent debonding of resin bonded FPD are high when abutments are mobiles. Fiber-reinforced composite resin FPD is often effective in these clinical situations to provide a conservative therapy option to restore the patient’s ease and esthetics by limiting mobility.

Гексанитрогексаазаизовюрцитан современный продукт, обладающий высокими значениями плотности и энтальпии образования, а также оптимальным кислородным балансом. Для обеспечения максимальной эффективности применения продукта необходимо добиться получения идеальных кристаллов СL-20 без внешних и внутренних дефектов, определенного полиморфного и гранулометрического состава. Такие важные показатели как форма кристаллов, дисперсность, а также гранулометрический состав продукта CL-20 закладывается на стадии кристаллизации. Полученные в результате кристаллы, неоднородны, имеют форму отличную от сферической - с острыми вершинами и выраженными гранями, а также значительную дефектность (сростки, раковины, трещины, сколы, выбоины) и широкое распределение частиц по размеру. Указанные характеристики закладываются на стадии кристаллизации CL-20, что делает ее одной из ключевых при синтезе нитрамина. В статье представлены результаты улучшения кристаллографической модификации кристаллов CL-20 при помощи гидромеханической окатки продукта в окатывателе, а также разработано разделение полидисперсного продукта на узкие размерные фракции, используя метод гидравлической классификации. В результате работы были установлены, условия проведения процесса окатки, а также условия эффективности метода гидроклассификации. Полученные результаты подтверждены ИК- и КР- спектроскопией.

Hexanitrohexaazaisowurtzitane is a modern product with high density and enthalpy of formation, as well as optimal oxygen balance. To ensure maximum efficiency of the product, it is necessary to obtain ideal crystals of CL-20 without external and internal defects, a certain polymorphic and particle size distribution. Important indicators such as the shape of the crystals, dispersion, as well as the particle size distribution of the CL-20 product are laid at the crystallization stage. The resulting crystals are heterogeneous, have a shape different from spherical - with sharp peaks and pronounced faces, as well as significant defectiveness (splices, shells, cracks, chips, potholes) and a wide distribution of particle size. These characteristics are laid at the crystallization stage of CL-20, which makes it one of the key in the synthesis of nitramine. The article presents the results of improving the crystallographic modification of CL-20 crystals using hydromechanical pelletizing of the product in the pelletizing agent, and the separation of the polydisperse product into narrow size fractions using the hydraulic classification method is developed. As a result of the work, the conditions for the rolling process and the conditions for the effectiveness of the hydroclassification method were established. The results are confirmed by IK and KR spectroscopy.

A Library Synthesis of Highly Isotactic Polyacrylamides with Various Pendant Groups and Their Isotacticity-Dependent Physical Properties
Authors: Pan Yuehang , Ouchi Makoto
Published: October 2024

The tacticity of vinyl polymers, i.e., the regularity of the side-chain stereochemistry, plays a crucial role in determining their physical properties. For example, the crystalline properties of isotactic polypropylene endow it with outstanding mechanical properties. In general, stereo-regulation during polymerization is greatly affected by even slight differences in the steric demand and/or position of the polar groups of the monomer side chains. In other words, no universal strategy to precisely control the tacticity for a given monomer with different pendant groups has been developed so far. Here, we provide a ground-breaking method for a library synthesis of highly isotactic polyacrylamides (>99% meso dyad content) with various pendant groups, including polar structures and di-substituted motifs. For that purpose, we designed an acrylamide monomer with a pendant that is sufficiently bulky to control the polymer tacticity that can be replaced by another pendant after polymerization. The transformable bulky monomer underwent iso-specific radical polymerization and subsequent one-pot aminolysis with a primary or secondary amine afforded a series of isotactic polyacrylamides (>20) derived from the added amine. Moreover, we clarified the isotacticity-dependent physical properties of the resulting polymers, such as their glass-transition temperature, crystalline properties, and solubility/thermo-responsibility in water, through a comparison with the corresponding atactic polyacrylamides.

Published: October 2024

Calculating anharmonic vibrational modes of molecules for interpreting experimental spectra is one of the most interesting challenges of contemporary computational chemistry. However, the traditional QM methods are costly for this application. Machine learning techniques have emerged as a powerful tool for substituting the traditional QM methods. Universal interatomic potentials (UIPs) hold a particular promise to deliver accurate results at a fraction of the cost of the traditional QM methods but the performance of UIPs for calculating anharmonic vibrational frequencies remains hitherto unknown. Here we show that despite a known excellent performance of the representative UIP ANI-1ccx for thermochemical properties, it fails for the anharmonic frequencies due to the original unfortunate choice of the activation function. Hence, we recommend evaluating new UIPs on anharmonic frequencies as an additional important quality test. To remedy the shortcomings of ANI-1ccx, we introduce its reformulation ANI-1ccx-gelu with the GELU activation function which is capable of calculating IR anharmonic frequencies with reasonable accuracy (close to B3LYP/6-31G*). We also show that our new UIP can be fine-tuned to obtain very accurate anharmonic frequencies for some specific molecules but more effort is needed to improve the overall quality of UIP and its capability for fine-tuning. The new UIP will be included as part of our universal and updatable AI-enhanced QM methods (UAIQM) platform and is available together with tutorials in open-source MLatom at https://github.com/dralgroup/mlatom. The calculations can also be performed via web browser at https://XACScloud.com.

Published: October 2024

The development of advanced relative humidity (r.h.) sensors holds immense potential for wearable applications where precise monitoring of environmental or physiological conditions is crucial. In this study, we explore the tunability of graphene oxide/reduced graphene oxide/titania nanocrystal (GO/rGO/TNC) hybrid films via photocatalytic reduction for resistive humidity sensing. First, we introduce a facile layer-by-layer spin-coating (LbL-SC) technique for the efficient fabrication of thin GO/TNC films (15-150 nm) on various substrates, using titania nanorods (TNRs) or nanoplates (TNPs). Second, we study the tunability of the films' electrical, optical, and structural properties set by the photocatalytic activity of the TNCs upon UV exposure (254 nm), by varying the illumination time, TNC type, and film thickness. We show that the electrical conductance of the films dramatically increases in presence of TNCs, and that the GO/rGO and (GO/rGO)/TNC ratio can be adjusted, with prolonged UV treatment resulting in the degradation of GO/rGO with rates depending on the films' composition and thickness. Third, we employ this method to tune the resistive sensing behavior of (GO/rGO)/TNC films on flexible substrates towards r.h. changes (ranges 35 – 85% and 1 – 80%). TNP-based films show superior humidity sensing performance to (GO/rGO)/TNR- and pristine GO/rGO films, with a sensitivity of up to 2.2 and response times down to 1 s. Depending on the film composition and the r.h. level, positive and negative responses are obtained. Gravimetric measurements reveal a similar mass uptake of water in all tested hybrid films, indicating that distinct resistive responses arise from differences in their chemical and electrical properties. Further, we demonstrate the use of these sensors for the detection of fluctuations in body-related humidity. Our findings highlight the potential of (GO/rGO)/TNC films and combinations thereof with tailored sensing characteristics as versatile platform for the design of advanced humidity sensors.
SLIC-SABRE at microtesla fields enables high levels of nuclear spin polarization without magnetic shielding
Authors: Kozinenko Vitaly , Kiryutin Alexey , Yurkovskaya Alexandra
Published: October 2024

Employing nuclear spin hyperpolarization to enhance NMR sensitivity opens new horizons for metabolic studies and chemical reaction monitoring. Among the hyperpolarization techniques, Signal Amplification by Reversible Exchange (SABRE) is prominent for its ability to transfer spin order from parahydrogen to target nuclei, especially 13C and 15N, without the chemical modification of the substrate under study. Despite its power, existing implementations of SABRE require expensive equipment like radiofrequency (RF) hardware and magnetic shielding. This paper demonstrates the SLIC-SABRE method at low magnetic fields as a low-cost and efficient technique for achieving high 15N polarization using a simple setup, consisting only of a small set of magnetic coils driven by a desktop PC sound card. The method yields up to 17% polarization across various SABRE-active molecules, outperforming the conventional SABRE-SHEATH approach and significantly enhancing the accessibility of hyperpolarization techniques.

Published: October 2024

1,4-Dihydronicotinamide adenine dinucleotide hydride (NADH) is an essential coenzyme existing in all living organisms. Due to its involvement in different biological process, fluorescence imaging of intracellular NADH levels at different pathological conditions has emerged as an interesting area of research. We report here the exploration of a fluorescent probe MQ-CN-BTZ as dual channel NADH imaging agent (green and red channel) for cellular system. Interestingly, depending on the ratio between probe and NADH concentration in solution phase, the probe showed emission at ~530 nm and ~660 nm when excited at 475 nm. It is to be noted that the probe showed very large Stokes shift of ~180 nm with respect to the longer wavelength emission with good fluorescence response towards NADH. In general, such large Stokes shift is highly beneficial for imaging applications largely due to better separation between emission and excitation spectra, and reduced spectral overlap. Finally, the probe was utilized to image the event of glycolysis pathway by employing 3-bromopyruvic acid (3-BrPA) as a glycolytic inhibitor that inhibits the activity of glyceraldehyde phosphate dehydrogenase (GAPDH) enzyme involved in a crucial step of the glycolysis. As the depletion of the NADH levels corresponds to the inactivity of GADPH upon treatment with inhibitor, we imaged the modulation of NADH concentration in cellular system in the presence of 3-BrPA inhibitor indicating the importance of glycolysis step in elevating NADH levels. Overall, the present study attempts to demonstrate the importance of fluorescent probe for imaging intracellular NADH in the presence of glycolytic inhibitor.

Published: October 2024

Understanding the evolving interactions between employment, social benefits, and families' well-being is key to designing better policies to both protect families and foster economic growth. Employment both overall and among those living in low-income families has been on a downward trajectory across the last three decades. One notable exception is that low-income women with children were increasingly likely to work between 1992 and 1999 in the aftermath of large changes to social safety net programs to provide more incentives and rewards for work. Since then, low-income women with children have been more likely to be employed than childless women. Over time, payments from social benefits programs have made up a larger share of income among low-income families with children and relatively higher earnings. Among low-income families without children, social benefits have not changed much over time.

Published: October 2024

This study sought to investigate the influence of transformational leadership style on employees’ job satisfaction and turnover intention in the South Africa Public Sector. Surprisingly, only fewer studies have been conducted in South Africa to find the reasons behind public sector employees job satisfaction and turnover intention. This study employed a quantitative research approach, and a self-administered structured questionnaire was used to collect data from 250 participants around the North West province of South Africa. The Statistical Package for the Social Sciences (SPSS) was used to analyse data. The statistical tests used including descriptive statistics, Cronbach’s alpha, and Spearman’s rank-order correlation. The results revealed that the positive correlation between transformational leadership and employees' job satisfaction leans towards a small effect size or no practically significant correlation (r = .228), while a negative correlation between transformational leadership and turnover intention leans towards a small effect or no practically significant correlation (r = -.091). Leaders in public sector departments should pay more attention to their followers’ job satisfaction and turnover intention to help them feel connected to the organisation. Recommendations for future research were also provided. The research results strengthen the significance of attributes of transformational leadership in leading officers in the public sector organisations in South Africa that wish to promote positive attitudes in employees and their work climate.
OPTIMIZATION AND ADAPTATION OF THE GLOBAL IDENTITY SCALE: MEASURING GLOBAL-LOCAL RELATIONS
Authors:   AL-FARABI KAZAKH NATIONAL UNIVERSITY, Maulsharif Mira
Published: October 2024

Global influences and local conditions shape diverse cultural identities, underscoring the importance of robust tools for measuring these phenomena. The aim of this research is to measure global-local relations reflecting various aspects of cultural dynamics that shape youth identity in Kazakhstan, based on an optimized and adapted Global Identity Scale (GIS). The study’s scientific and practical significance emerges as global influences reshape local structures, requiring methodologies to capture these changes. These measurements help understand and address the challenges of demographic groups in a globalizing world. Methodology: The study optimizes and adapts GIS to explore the cultural preferences of Kazakhstani student youth. Data were collected through surveys, with participants equally selected from two groups: ethnically homogeneous (Kazakhs, N=225) and heterogeneous (others, N=225). A total of 426 cases were analyzed in IBM SPSS. Constructs such as "globalists", "localists", "glocalists", and "negativists" were developed to cover different identity orientations based on the GIS scale. Main results and analysis, conclusions: Data analysis using paired t-tests indicated that most statements show statistically significant differences between the assessments of globalists and localists. The results reflect a predominance of globalization while maintaining traditional local identities. This combination indicates a generational shift towards global identity, independent of ethnic background. This study contributes valuable insights to the ongoing discourse on global and local identity, particularly in a post-colonial context like Kazakhstan, and expands academic understanding of cultural identity dynamics. The study’s practical significance lies in its provision of significant information. Future work could expand through panel studies to track changes in identity perception among a broader youth demographic over time, particularly in response to global events or national policy changes.

Authors: Faiza Makhdoom , Jamshaid Ul Rahman , Naveed Anjum
Published: October 2024

Nonlinear differential equations play a pivotal role in modeling various physical phenomena, capturing their oscillatory behaviors. Numerous analytic and numerical methods have been developed to obtain precise or approximate solutions for nonlinear dynamics. This study introduces a novel approach utilizing neural network strategies, known for their computational flexibility. This study proposed a novel architecture for deep neural networks that is intended to simulate the nonlinear oscillations of two systems. It has been modified to include an oscillatory activation function called the amplifying sine unit. This study compares the results from our customized neural networks with those from the conventional stable and reliable numerical technique of the Runge-Kutta method of order four. Remarkably, there is striking agreement between the outcomes of the two methods, highlighting the ability of deep neural networks to identify nonlinear dynamical behaviors without requiring explicit conversion of mathematical models into an equation system.

Published: October 2024

Introduction. The article is dedicated to the problem of evaluating educational achievements of students with limited health abilities in the classes of physics and mathematics. The results of the research aimed at the study of professional views of the teachers on the issues of conducting interim certification of students at the level of basic general education are presented in this work.

   The actuality of the study is determined by the need to improve the quality of general education of students with OHS, which is directly related to the assessment of their educational results.

   Materials and Methods. The study was conducted among physics and mathematics teachers using an online questionnaire, consisting of problems, the answers to which characterize the professional positions of teachers in terms of defining goals, developing assessment tools, using a differentiated approach and creating special conditions when conducting midterm assessment and assessing the educational results of students with special educational needs.

   Results. The results of the study showed a fairly wide variability of the views of the teachers on the subject studied. The majority of respondents point to the need to modify and differentiate the ratings by the degree of complexity, allowing to provide different types of assistance to students, and consider it necessary to create special conditions. At the same time, in practice, part of the teachers address the problem quite formally, and in some cases the special educational needs of the students are ignored.

   Discussion and Conclusions. According to the results of the study, the author, on the one hand, notes the insufficient scientific development of the problem, on the other hand, he identifies some professional deficits of physics and mathematics teachers in terms of competencies related to the assessment of educational results. These deficits, according to the author, can be overcome by developing and including in the content of the main and additional professional educational programs sections related to the study of the special educational needs of different categories of students with disabilities, which determine the features of assessing their educational achievements, including the features of adapting assessment tools and assessment procedures, creating special conditions.
Assertive behavior. Structural analysis
Authors: Gaponova S. A. , Kornilova N. S.
Published: October 2024

Introduction. A brief history of the emergence of the concepts of “assertiveness” and «assertive behavior» is presented , and their definitions are given. The importance of assertive behavior for personality development is shown. Argues for the need to investigate the structural components of assertive behavior.

   Materials and Methods. The research methods used were: structural analysis of modern scientific literature on the research problem, summarizing, comparing, systematizing and interpreting data.

   Results. Based on the analysis, comparison and systematization of the concepts of assertiveness and assertive behavior presented in modern domestic and foreign scientific literature, a complex of the most significant structural components of assertive behavior is identified. These include: self-confidence, autonomy, responsibility, self-control, communication skills, positive and tolerant attitudes, constructive ways of resolving conflicts and disputes. A model of assertive behavior is presented. It is shown that in the works aimed at increasing assertiveness and assertive behavior, the emphasis is placed on improving individual personality traits, but this approach will not give an optimal result, since it is necessary to have a complex impact on all components of the assertive conduction structure.

   Discussion and Conclusions. The study of theoretical approaches to the study of assertive behavior allows us to propose an expanded definition of this concept as a holistic entity, identify its main structural elements, and develop a model of assertive behavior. It is shown that when developing formative programs of assertive behavior it is necessary to have a complex impact on all components of its structure.
