Published: March 2023

It has been demonstrated that cancer stem cells (CSCs) go through metabolic changes that differentiate them from non-CSCs. The altered metabolism of CSCs plays a vital role in tumor initiation, progression, immunosuppression, and resistance to conventional therapy. Therefore, defining the role of CSC metabolism in carcinogenesis has emerged as a main focus in cancer research. Two natural flavonoids, apigenin and isovitexin, have been shown to act synergistically with conventional chemotherapeutic drugs by sensitizing CSCs, ultimately leading to improved therapeutic efficacy. The aim of this study is to present a critical and broad evaluation of the anti-CSC capability of apigenin and isovitexin in different cancers as novel and untapped natural compounds for developing drugs. A thorough review of the included literature supports a strong association between anti-CSC activity and treatment with apigenin or isovitexin. Additionally, it has been shown that apigenin or isovitexin affected CSC metabolism and reduced CSCs through various mechanisms, including the suppression of the Wnt/β-catenin signaling pathway, the inhibition of nuclear factor-κB protein expression, and the downregulation of the cell cycle via upregulation of p21 and cyclin-dependent kinases. The findings of this study demonstrate that apigenin and isovitexin are potent candidates for treating cancer due to their antagonistic effects on CSC metabolism.

Authors: Ji Guangchong , Kanno Yusuke , Nisisako Takasi
Published: March 2023

Step emulsification, which uses a geometry-dependent mechanism for generating uniformly sized droplets, has recently gained considerable attention because of its robustness against flow fluctuations. However, like shear-based droplet generation, step emulsification is susceptible to impurities caused by satellite droplets. Herein, we demonstrate the integration of deterministic lateral displacement (DLD) to separate the main and satellite droplets produced during step emulsification. Step-emulsification nozzles (16 μm deep) in the upstream region of the proposed device were arrayed on the sidewalls of the main channel (91 μm deep). In the downstream region, the DLD micropillars were arrayed periodically with a critical diameter (cut-off value for size-based separation) of 37 μm. When an acrylate monomer and aqueous polyvinyl alcohol solution were infused as the dispersed and continuous phases, respectively, the nozzles produced monodisperse main droplets in the dripping regime, with an average diameter of ~60 μm, coefficient of variation (CV) value below 3%, and satellite droplets of ~3 μm. Upon entering the DLD region near the sidewall, these main and satellite droplets were gradually separated through the pillars based on their sizes. Finally, off-chip photopolymerization yielded monodisperse polymeric microspheres with an average diameter of 55 μm and a CV value of 2.9% (n = 202).

Published: March 2023

Electrohydrodynamic jet (E-jet) printing has broad application prospects in the preparation of flexible electronics and optical devices. Ejection cycle time and droplet size are two key factors affecting E-jet-printing quality, but due to the complex process of E-jet printing, it remains a challenge to establish accurate relationships among ejection cycle time and droplet diameter and printing parameters. This paper develops a model based on random forest regression (RFR) for E-jet-printing prediction. Trained with 72 groups of experimental data obtained under four printing parameters (voltage, nozzle-to-substrate distance, liquid viscosity, and liquid conductivity), the RFR model achieved a MAPE (mean absolute percent error) of 4.35% and an RMSE (root mean square error) of 0.04 ms for eject cycle prediction, as well as a MAPE of 2.89% and an RMSE of 0.96 μm for droplet diameter prediction. With limited training data, the RFR model achieved the best prediction accuracy among several machine-learning models (RFR, CART, SVR, and ANN). The proposed prediction model provides an efficient and effective way to simultaneously predict the ejection cycle time and droplet diameter, advancing E-jet printing toward the goal of accurate, drop-on-demand printing.
Geochemical Characteristics of the Granodiorite Porphyry in Dongxiang W-Cu Deposit, SE China
Authors: Cai Yitao , Ni Pei , Wang Guoguang , Chen Hui
Published: March 2023

The Dongxiang tungsten–copper deposit is a large W–Cu deposit located in the northeast of Jiangxi province in south China. Previous studies have mainly considered the geochemical and isotopic attributes of the ore deposit, but information is still lacking on the genesis and setting of Dongxiang W–Cu mineralization-related intrusive rocks. This paper presents systematic elements and Sr–Nd–Hf isotopic data of the Dongxiang granodiorite porphyry. The Dongxiang granodiorite porphyry is intermediate–acidic in composition, with SiO2 contents of 60.00–75.16 wt.%, Al2O3 contents of 10.15–18.53 wt.%, an K2O contents of 2.95–4.28 wt.%. The REEs content ranges from 64.2 to 198.1 ppm, with LREE/HREE ratios of 7.67–17.47. It is characterized by adakitic geochemical affinities with high Sr/Y and (La/Yb)N ratios but low Y and Yb contents. A slight Eu anomaly, extreme depletion in Y and Yb, relatively low MgO content, and relatively high 207Pb/204Pb ratios together indicate that the Dongxiang granodiorite porphyry was likely derived from partial melting of the thickened lower continental crust. Based on zircon εHf(t) values (−11.8–−4.5), two-stage Hf model ages (1.33–1.94 Ga), and the regional geological setting, it can be inferred that Dongxiang granodiorite porphyry magma is mainly derived from Neoproterozoic juvenile crust with the involvement of Paleoproterozoic ancient crust.

Published: March 2023

Herein, we carefully investigated the Fe3+ doping effects on the structure and electron distribution of Cr2O3 nanoparticles using X-ray diffraction analysis (XRD), maximum entropy method (MEM), and density functional theory (DFT) calculations. We showed that increasing the Fe doping induces an enlargement in the axial ratio of c/a, which is associated with an anisotropic expansion of the unit cell. We found that as Fe3+ replaces Cr in the Cr2O3 lattice, it caused a higher interaction between the metal 3d states and the oxygen 2p states, which led to a slight increase in the Cr/Fe–O1 bond length followed by an opposite effect for the Cr/Fe–O2 bonds. Our results also suggest that the excitations characterize a well-localized bandgap region from occupied Cr d to unoccupied Fe d states. The Cr2O3 and Fe-doped Cr2O3 nanoparticles behave as Mott–Hubbard insulators due to their band gap being in the d−d gap, and Cr 3d orbitals dominate the conduction band. These findings suggest that the magnitude and the character of the electronic density near the O atom bonds in Cr2O3 nanoparticles are modulated by the Cr–Cr distances until its stabilization at the induced quasi-equilibrium of the Cr2O3 lattice when the Fe3+ doping values reaches the saturation level range.
Shape-Factor Impact on a Mass-Based Hybrid Nanofluid Model for Homann Stagnation-Point Flow in Porous Media
Authors: Li Shiyuan , You Xiangcheng
Published: March 2023

This paper studies the impact of shape factor on a mass-based hybrid nanofluid model for Homann stagnation-point flow in porous media. The HAM-based Mathematica package BVPh 2.0 is suitable for determining approximate solutions of coupled nonlinear ordinary differential equations with boundary conditions. This analysis involves discussions of the impact of the many physical parameters generated in the proposed model. The results show that skin friction coefficients of Cfx and Cfy increase with the mass of the first and second nanoparticles of the hybrid nanofluids w1 and w2 and with the coefficient of permeability in porous media. For the axisymmetric case of γ = 0, when w1 = w2 = 10 gr, wf = 100 gr and Cfx = Cfy = 2.03443, 2.27994, 2.50681, and 3.10222 for σ = 0, 1, 2, and 5. Compared with w1 = w2 = 10 gr, wf = 100 gr, and σ = 0, it can be found that the wall shear stress values increase by 12.06%, 23.21%, and 52.48%, respectively. As the mass of the first and second nanoparticles of the mass-based hybrid nanofluid model increases, the local Nusselt number Nux increases. Values of Nux obviously decrease and change with an increase in the coefficient of permeability in the range of γ < 0; otherwise, Nux is less affected in the range of γ > 0. According to the calculation results, the platelet-shaped nanoparticles in the mass-based hybrid nanofluid model can achieve maximum heat transfer rates and minimum surface friction.

This study discloses the development of NiCr LDH, Ag@NiCr LDH, and Pd@NiCr LDH bifunction catalysts using a hydrothermal coprecipitation method followed by sol immobilization of metallic nanoparticles. The structures and morphologies of the synthesized nanocomposites were analyzed using FTIR, XRD, XPS, BET, FESEM-EDX, and HRTEM. The catalytic effectiveness of the samples was evaluated by tracking the progression of NaBH4-mediated nitrobenzene (NB) reduction to aniline and CO oxidation using UV-visible spectrophotometry and an infrared gas analyzer, respectively. Pd@NiCr LDH displayed much higher performance for both reactions than the bare NiCr LDH. The catalyst Pd@NiCr LDH showed robust catalytic activity in both the oxidation of carbon monoxide (T50% (136.1 °C) and T100% (200.2 °C)) and NaBH4-mediated nitrobenzene reduction (98.7% conversion and 0.365 min−1 rate constant). The results disclose that the Ni2+@ Cr3+/Cr6+ @Pd° ion pairs inside the LDH act as a charge transfer center and hence significantly enhance the catalytic performance. As a result, this research offers the novel NiCr LDH catalyst as a bifunctional catalyst for air depollution control and the organic transformation process.

Published: March 2023

The concept of privileged structure has been used as a fruitful approach for the discovery of novel biologically active molecules. A privileged structure is defined as a semi-rigid scaffold able to display substituents in multiple spatial directions and capable of providing potent and selective ligands for different biological targets through the modification of those substituents. On average, these backbones tend to exhibit improved drug-like properties and therefore represent attractive starting points for hit-to-lead optimization programs. This article promotes the rapid, reliable, and efficient synthesis of novel, highly 3-dimensional, and easily functionalized bio-inspired tricyclic spirolactams, as well as an analysis of their drug-like properties.

The Effect of Accelerated Aging on the Molecular Weight and Thermal and Mechanical Properties of Polyester Yarns Containing Ceramic Particles
Authors: Mijas Gabriela , Riba-Moliner Marta , Cayuela Diana
Published: March 2023

The accelerated aging of polyethylene terephthalate (PET) multifilament yarns containing nano or microparticles of titanium dioxide (TiO2), silicon carbide (SiC), or fluorite (CaF2) at a maximum percentage of 2% has been studied. For this, the yarn samples were introduced into a climatic chamber at 50 °C, 50% relative humidity, and an ultraviolet A (UVA) irradiance of 1.4 W/m2. They were then removed from the chamber after periods of between 21 and 170 days of exposure. Subsequently, the variation in weight average molecular weight, number molecular weight, and polydispersity was evaluated by gel permeation chromatography (GPC), the surface appearance was evaluated using scanning electron microscopy (SEM), the thermal properties were evaluated using differential scanning calorimetry (DSC), and the mechanical properties were evaluated using dynamometry. The results showed that, at the test conditions, there was degradation in all of the exposed substrates, possibly due to the excision of the chains that make up the polymeric matrix, which resulted in the variation in the mechanical and thermal properties depending on the type and size of the particle used. This study provides insight into the evolution of the properties of PET-based nano- and microcomposites and might be helpful when selecting materials for specific applications, which is of great interest from an industrial point of view.

Published: March 2023

In this research, the porous polymer structures (IPN) were made from natural isoprene rubber (NR) and poly(methyl methacrylate) (PMMA). The effects of molecular weight and crosslink density of polyisoprene on the morphology and miscibility with PMMA were determined. Sequential semi-IPNs were prepared. Viscoelastic, thermal and mechanical properties of semi-IPN were studied. The results showed that the key factor influencing the miscibility in semi-IPN was the crosslinking density of the natural rubber. The degree of compatibility was increased by doubling the crosslinking level. The degree of miscibility at two different compositions was compared by simulations of the electron spin resonance spectra. Compatibility of semi-IPNs was found to be more efficient when the PMMA content was less than 40 wt.%. A nanometer-sized morphology was obtained for a NR/PMMA ratio of 50/50. Highly crosslinked elastic semi-IPN followed the storage modulus of PMMA after the glass transition as a result of certain degree of phase mixing and interlocked structure. It was shown that the morphology of the porous polymer network could be easily controlled by the proper choice of concentration and composition of crosslinking agent. A dual phase morphology resulted from the higher concentration and the lower crosslinking level. This was used for developing porous structures from the elastic semi-IPN. The mechanical performance was correlated with morphology, and the thermal stability was comparable with respect to pure NR. Investigated materials might be interesting for use as potential carriers of bioactive molecules aimed for innovative applications such as in food packaging.

Published: March 2023

Organic solar cells (OSCs) demonstrating high power conversion efficiencies have been mostly fabricated using halogenated solvents, which are highly toxic and harmful to humans and the environment. Recently, non-halogenated solvents have emerged as a potential alternative. However, there has been limited success in attaining an optimal morphology when non-halogenated solvents (typically o-xylene (XY)) were used. To address this issue, we studied the dependence of the photovoltaic properties of all-polymer solar cells (APSCs) on various high-boiling-point non-halogenated additives. We synthesized PTB7-Th and PNDI2HD-T polymers that are soluble in XY and fabricated PTB7-Th:PNDI2HD-T-based APSCs using XY with five additives: 1,2,4-trimethylbenzene (TMB), indane (IN), tetralin (TN), diphenyl ether (DPE), and dibenzyl ether (DBE). The photovoltaic performance was determined in the following order: XY + IN < XY + TMB < XY + DBE ≤ XY only < XY + DPE < XY + TN. Interestingly, all APSCs processed with an XY solvent system had better photovoltaic properties than APSCs processed with chloroform solution containing 1,8-diiodooctane (CF + DIO). The key reasons for these differences were unraveled using transient photovoltage and two-dimensional grazing incidence X-ray diffraction experiments. The charge lifetimes of APSCs based on XY + TN and XY + DPE were the longest, and their long lifetime was strongly associated with the polymer blend film morphology; the polymer domain sizes were in the nanoscale range, and the blend film surfaces were smoother, as the PTB7-Th polymer domains assumed an untangled, evenly distributed, and internetworked morphology. Our results demonstrate that the use of an additive with an optimal boiling point facilitates the development of polymer blends with a favorable morphology and can contribute to the widespread use of eco-friendly APSCs.

Published: March 2023

This study aims to develop a new refreshing feeling, ecological, and antimicrobial fabrics for medicinal applications. The geranium essential oils (GEO) are incorporated into polyester and cotton fabrics by different methods, such as ultrasound, diffusion, and padding. The effect of solvent, nature of fibers, and treatment processes were evaluated via the thermal properties, the color strength, the odor intensity, the wash fastness, and the antibacterial activities of the fabrics. It was found that the ultrasound method was the most efficient process for incorporation of GEO. Ultrasound produced a great effect on the color strength of the treated fabrics, suggesting the absorption of geranium oil in fiber surface. The color strength (K/S) increased from 0.22 for the original fabric to 0.91 for the modified counterpart. In addition, the treated fibers showed appreciable antibacterial capacity against Gram-positive (Staphylococcus epidermidis) and Gram-negative (Escherichia coli) bacteria strains. Moreover, the ultrasound process can effectively guarantee the stability of geranium oil in fabrics without decreasing the significant odor intensity and antibacterial character. Based on the interesting properties like ecofriendliness, reusability, antibacterial, and a refreshing feeling, it was suggested that textile impregnated with geranium essential oil might be used as a potential material in cosmetic applications.
Structural Strategies for Supramolecular Hydrogels and Their Applications
Authors: Sánchez-Fernández José Antonio
Published: March 2023

Supramolecular structures are of great interest due to their applicability in various scientific and industrial fields. The sensible definition of supramolecular molecules is being set by investigators who, because of the different sensitivities of their methods and observational timescales, may have different views on as to what constitutes these supramolecular structures. Furthermore, diverse polymers have been found to offer unique avenues for multifunctional systems with properties in industrial medicine applications. Aspects of this review provide different conceptual strategies to address the molecular design, properties, and potential applications of self-assembly materials and the use of metal coordination as a feasible and useful strategy for constructing complex supramolecular structures. This review also addresses systems that are based on hydrogel chemistry and the enormous opportunities to design specific structures for applications that demand enormous specificity. According to the current research status on supramolecular hydrogels, the central ideas in the present review are classic topics that, however, are and will be of great importance, especially the hydrogels that have substantial potential applications in drug delivery systems, ophthalmic products, adhesive hydrogels, and electrically conductive hydrogels. The potential interest shown in the technology involving supramolecular hydrogels is clear from what we can retrieve from the Web of Science.
Recycling of Heterogeneous Mixed Waste Polymers through Reactive Mixing
Authors: Titone Vincenzo , Gulino Emmanuel Fortunato , La Mantia Francesco Paolo
Published: March 2023

Anything that is not recycled and/or recovered from waste represents a loss of raw materials. Recycling plastics can help to reduce this loss and to reduce greenhouse gases, improving the goal of the decarbonization of plastic. While the recycling of single polymers is well assessed, the recycling of mixed plastics is very difficult because of the strong incompatibility among the different polymers usually present in urban waste. In this work, heterogeneous mixed polymers, i.e., polyethylene (PE), polypropylene (PP), polystyrene (PS) and polyethylenetherephthalate (PET) were processed using a laboratory mixer under different conditions of temperature, rotational speed and time to evaluate the effect of the above parameters on morphology, viscosity and mechanical properties of the final blends. Morphological analysis shows a strong incompatibility between the polyethylene matrix and the other dispersed polymers. The blends show, of course, a brittle behavior, but this behavior slightly improves with decreasing temperature and increasing rotational speed. A brittle-ductile transition was observed only at a high level of mechanical stress obtained by increasing rotational speed and decreasing temperature and processing time. This behavior has been attributed to both a decrease in the dimensions of the particles of the dispersed phase and to the formation of a small amount of copolymers that act as adhesion promoters between matrix and dispersed phases.

Authors: Wang Shihe , Chen Jianlin , Tsukamoto Takashiro , Tanaka Shuji
Published: March 2023

In this paper, we report a multi-ring disk resonator with elliptic spokes for compensating the aniso-elasticity of (100) single crystal silicon. The structural coupling between each ring segments can be controlled by replacing the straight beam spokes with the elliptic spokes. The degeneration of two n = 2 wineglass modes could be realized by optimizing the design parameters of the elliptic spokes. The mode-matched resonator could be obtained when the design parameter, aspect ratio of the elliptic spokes was 25/27. The proposed principle was demonstrated by both numerical simulation and experiment. A frequency mismatch as small as 1330 ± 900 ppm could be experimentally demonstrated, which was much smaller than that of the conventional disk resonator, which achieved as high as 30,000 ppm.
How Does the Public Receive Information about Vaccines during the COVID-19 Pandemic? A Nationwide Cross-Sectional Study in Spain
Authors: Catalan-Matamoros Daniel , Langbecker Andrea
Published: March 2023

Spain has been one of the most severely impacted countries by COVID-19. Vaccination against COVID-19 is one of the most successful preventive strategies. However, some citizens show vaccine resistance, in part due to widespread disinformation that has been disseminated since the pandemic’s start. The objective of this study was to explore the characteristics of the Spanish population in terms of their use of traditional and social media for COVID-19 vaccine-related information. A countrywide survey was conducted in June 2022 following a descriptive cross-sectional analysis. Respondents declared that 80.4% had received the full schedule of COVID-19 vaccination, and over 60% would take the booster dosage without hesitation. The major reasons for not having the booster vaccine were possible health risks (37%), and a lack of trust in the COVID-19 vaccines (29%). More than 85% of respondents closely followed the news on this topic, with the journalistic media (27%) and health authorities (26%) considered to be the most important sources for pandemic information, while social media was considered by 9% of respondents. Further collaboration between the media and health professionals, as well as campaigns to enhance vaccination uptake of the COVID-19 booster dose, might be considered in future strategies.

The genus Dunaliella belongs to the division Chlorophyta and is known for its ability to survive in highly saline environments. Dunaliella is an important source of carotenoids, especially beta-carotene and has a wide range of applications. In this study, we aimed to isolate and identify Dunaliella strains from active and abandoned saltworks in Greece. Four seasonal samplings were carried out in seven active saltworks and two samplings were performed in an abandoned saltwork throughout the year 2020. Strains were characterized based on their morphological and phylogenetic traits, whilst their beta-carotene potential were evaluated. Fifteen (15) Dunaliella strains were isolated and classified into nine species based on morphological and morphometrical features. The isolated strains were assigned to different species such as D. parva, D. granulata, D. minuta, D. terricola, D. asymmetrica, D. bioculata, D. viridis, D. minutissima, and D. polymorpha. The results of the phylogenetic analysis indicate the formation of distinct clades among different Dunaliella species and suggest that morphological and morphometrical features may not always align with the phylogenetic position of species in the Dunaliella clade. Strains were found to produce a low amount of beta-carotene under default laboratory conditions. This study comprises the first phylogenetic inference of several Dunaliella species and highlights a gap on molecular data for Dunaliella spp. We provide valuable information on the diversity of Dunaliella strains in the saltworks of Greece, which can be used for further research and biotechnological applications.

Influence of Breхit on Scotland's aspiration for independence
Authors: Mukha Viktoriia ,   National Academy for Public Administration under the President of Ukraine
Published: March 2023

It is proved that Brexit has political and socio-economic implications for UK development. It is grounded that one of the consequences of Brexit may be a further fragmentation within the UK itself. London experiences many contradictions in relations with Scotland, Wales and Northern Ireland nowadays. In Scotland, after the referendum on the independence of the autonomous region, in which 55% of Scots opposed the secession from the UK in 2014, the movement for independence has strengthened its position. Part of the rise in such sentiment in Scottish society is due to concerns over Brexit. In 2021 the unity of the UK's autonomous regions may be threatened by the strengthening of nationalist sentiments in Scotland, as well as in Northern Ireland and Wales. The Scots do not want to lose the economic benefits of a duty-free customs regime with the EU and historic ties with Europe. Leaving the EU common market will be a devastating blow to investment and employment in Scotland. A break with London will also be costly, as Scotland's economy has close ties with the UK.
Collaborationism in Ukraine in the context of russian aggression: the problem of legal definition
Authors: Trofymenko Anastasia ,   Mariupol State University
Published: March 2023

The article focuses on the problem of the legal definition of collaborationism in Ukraine in the context of Russian aggression. The need to ban collaborationism at the legislative level has been on the agenda since the occupation of Crimea and the war in Donbass. However, the normative definition of defecting to the aggressor's side and knowingly collaborating with the occupying authorities is debatable. This is because in the face of Russian aggression, loss of life and the need to restore state sovereignty, the state should normatively define this phenomenon and establish fair punishment, but on the other hand, the threat of punishment for collaborating with the enemy in the temporarily occupied territories hinders the processes of de-occupation and reintegration. The author reviewed the main conceptual approaches to the definition of collaborationism. It has not been found to have a single established definition either in international law, political circles or academic research. Based on the interpretations considered, the broad approach, which understands collaborationism as assisting the enemy in any way, and the narrow approach, which explains it solely as conscious and voluntary cooperation with the occupier to the detriment of the state, are highlighted. The definition of collaborationism in Ukrainian law has been established, in particular its identification with high treason, while noting that collaborationism includes more forms of cooperation with the occupier than are specified in the Criminal Code of Ukraine, especially given the "hybrid nature" of Russian aggression. The process of finding ways to legislate and criminalise collaborationism is explored through an analysis of the main provisions of the draft laws submitted to the Verkhovna Rada of Ukraine since 2017. The first draft laws needed considerable refinement, detailing the definitions of the term "collaborationism" itself, which were not self-sufficient and did not emphasise the voluntariness or consciousness of such activity. The draft laws of 2021, currently before the Verkhovna Rada, largely addresses these shortcomings by defining in detail all the forms of activity that should qualify as collaborationism, giving them a better chance of coming into force. Emphasis has been placed on the need for a balanced, cautious and clear interpretation of this concept in Ukrainian legislation that will ensure that appropriate and fair legal liability for this criminal offence is established, while not impeding the process of de-occupation and reintegration.

Authors: Averyanov Andriy ,   Mariupol State University
Published: March 2023

Attention is paid to the features of political process in the Donetsk region after the Revolution of Dignity in Ukraine and the beginning of hostilities in eastern Ukraine. The main components of the political process were analyzed. In particular, the statutory documents of political parties were considered, the results of all-Ukrainian and local elections were analyzed, and public organizations were characterized. The author concluded that regional economic and socio-political conditions have led to a general pluralization of the political system. This manifested itself in the appearing of new parties in the region, the fall rating of left-wing parties and the reformatting principle of forming the political sympathies of citizens. The growth of public interest in politics has become relevant.

Indian banking sector is invariably presumed to be one of the most important systems in the economy. Banking sectors are considered as the life blood of the Indian economy as they play an important and vital role in the economic activities. This study examines the overall performance of selected private sector banks using capital adequacy, asset quality, management effectiveness, earnings quality and liquidity level (CAMEL approach) over the period 2013-2022. Although profitability indicators (such as return on assets, return on equity and net profit margin) present the performance of selected private sector banks, it would be more appropriate to use the CAMEL Approach as a tool to assess overall performance. Because the performance of banks does not only depend on the level of NPAs or profitability, it is primarily based on various dimensions. To consider this point of view, the researchers adopted the CAMEL approach for this study to evaluate the overall financial performance of selected private sector banks.

Influence Between Bank Spread Rate and NPA
Authors: Nivetha P
Published: March 2023

This research aimed to determine how interest rate dispersion affects the quantity of bad loans at Indian financial institutions. The research strategy used in this analysis of Indian Bank data was descriptive in nature. The Bank Supervision Report was employed as a secondary source for this study’s data collection. The correlation between interest rate spread and loan default was investigated using quantitative and qualitative methods of data analysis. Charts, tables, and pie diagrams were used to illustrate the information. The research found that the cost of loans paid to borrowers is affected by interest rate spread, and that interest rate regulations have far-reaching implications on asset non-performance since they determine the interest rate spread in banks and assist alleviate moral hazards incidental to NPAs. As interest rates are benchmarked against the associated non-performing assets and non-performing assets are attributed to high cost of loans, credit risk management techniques indirectly affect the value of a bank’s interest rate spread. Since an inefficient interest rate policy might raise interest rates and, in turn, NPAs, the study suggests that commercial banks in RBI should evaluate their clientele and charge interest rates properly. To lower the number of nonperforming loans (NPAs), they implement strict rules on interest rates charged by banks in order to regulate their interest rate spread and improve periodic/regular credit risk monitoring of their loan portfolios.

The purpose of the study was to find out the effects of high intensity interval training and Low intensity interval training on selected motor fitness components namely speed and agility. To achieve this purpose of the study, forty five men students studying Annamalai University, Annamalai Nagar, Chidambaram, Tamil Nadu and India were selected as subjects at random. Their age ranged between 18 to 24 years. The selected subjects were divided into three equal groups of fifteen each namely high intensity interval training group, Low intensity interval training group and control group. The experimental group I underwent high intensity interval training and group II underwent Low intensity interval training for three days per week for twelve weeks whereas the control group maintained their daily routine activities and no special training was given to them. The following motor fitness components namely speed and agility were selected as criterion variables. The subjects of the three groups were tested on selected motor fitness components namely speed and agility using standardized tests namely 50 mts run and shuttle run at prior and immediately after the training period. The collected data were analyzed statistically through analysis of covariance (ANCOVA) to find out the significant difference, if any among the groups. Whenever the obtained “F” ratio was found to be significant, the Scheffe’s test was applied as post hoc test to find out the paired mean difference, if any. The .05 level of confidence was fixed to test the level of significance which was considered as an appropriate. The results of the study showed that there was a significant difference exist among high intensity interval training group, Low intensity interval training group and control group on selected motor fitness components namely speed and agility. And also high intensity interval training group and Low intensity interval training group showed significant improvement on speed and agility when compared to control group.

Four Interactions Between AI and Education: Broadening Our Perspective on What AI Can Offer Education
Authors: Rismanchian Sina , Doroudi Shayan
Published: March 2023

In the 30th anniversary of the International Artificial Intelligence in Education Society, there is a need to look back to the past to envision the community's future. This paper presents a new framework (AIxEd) to categorize different interactions between artificial intelligence (AI) and education. We use our framework to compare papers from two early proceedings of AIED (1985 \& 1993) with AIED proceedings papers and IJAIED papers published in 2021. We find that two out of four kinds of interactions between AI and education were more common in the early stages of the field but have gained less attention from the community in recent years. We suggest that AI has more to offer education than a pragmatic toolkit to apply to educational problems; rather, AI also serves as an analogy for thinking about human intelligence and learning. We conclude by envisioning future research directions in AIED from the lens of our framework.
