Recyclable Pt/Glycerol-Catalytic System for Heterophase Hydrosilylation
Authors: Goncharova Irina , Kholodkov Dmitry , Beletskaya Irina , Arzumanyan Ashot
Published: June 2024

This study introduces the development of highly efficient and simple recyclable catalysts for hydrosilylation using polyols as a medium for heterophase catalytic systems. The system consists of a commercially available platinum precatalyst – K2PtCl4, and a surplus green solvent – glycerol (Gly), which can be easily prepared by dissolving K2PtCl4 in Gly at r.t. under air. The method allows for at least 60 cycles with a quantitative yield of the anti-Markovnikov product in air at r.t.; the product can be isolated from the catalytic system by simple decantation. The reaction proceeds at a high rate (from 10 min per cycle) even with small catalyst loadings (0.001-0.1 mol% Pt).

The stability and activity of supported single-atom catalysts (SACs) represent critical yet opposing factors limiting our ability to explore and exploit their unique properties. This study demonstrates the operation of a switchable catalyst that is activated in the presence of surface intermediates and reverts to a stable but inactive form when the reaction is completed. We employ atomically defined Rh/Fe3O4(001) catalysts to demonstrate how structurally stable Rh, bound in surface octahedral Fe sites, gets destabilized to form highly active Rh adatoms and small clusters. Conversion of formic acid, leading initially to surface formate and hydroxyl species, is employed as a model reaction to probe the dynamics of such processes. We find that surface hydroxyl recombination to water through the Mars-van Krevelen mechanism reduces Rh coordination, triggering its conversion to active Rh adatoms. Since such lattice oxygen exchange is observed in many acid-base and redox chemistries, the process can be broadly applicable to controlling the activation of the range of SACs.

The π-conjugate system is the key to charge transport properties in organic semiconductors. Four multifunctional mesogenic materials were designed and synthesised from 2-amino anthracene and para-hydroxybenzaldehyde. Each material contains a central, rigid phenyl-anthracene core and one flexible alkyloxy chain with different lengths based on the concept of combining liquid crystal (LC) materials featuring facile processability, highly ordered alignment, and effective charge transport. (E)-N-(anthracen-2-yl)-1-(4-(alkyloxy) phenyl) methanimine (n-OPIA) with n = 8, 10, 12, and 16 was chemically characterized by nuclear magnetic resonance spectroscopy and high-resolution mass spectrometry. Their thermal behaviours were performed by means of differential scanning calorimetry, and polarised optical microscopy and showed differences in mesomorphic behaviours with respect to the alkyloxy chain length. Concerning their frontier molecular energy levels, they were studied by optical spectroscopy and cyclic voltammetry and compared to values obtained via ab initio density-functional theory (DFT) calculations. The LC Field-Effect Transistors (LC-FETs) using solvent vapour enhanced drop casting based n-OPIA material showed efficient electrical parameters and interesting photoconductive properties, indicating their potential applications in multifunctional integrated devices.

Bismuth ferrates, specifically perovskite-type BiFeO₃ and mullite-type Bi₂Fe₄O₉, hold significant technological promise as catalysts, photovoltaics, and room-temperature multiferroics. However, challenges arise due to their frequent co-crystallization, particularly in the nano-regime, hindering the production of phase pure materials. This study unveils a controlled sol-gel crystallization approach, elucidating the phase formation complexities in the bismuth ferrate oxide system by coupling thermochemical analysis and total scattering with pair distribution function analysis. We tune the crystallization pathways by adjusting the metal to complexing agent ratio and pH during precursor preparation resulting in preferential crystallization of either BiFeO3 or Bi2Fe4O9. Although all precursors undergo an amorphization process during heating, our results demonstrate a consistent correlation between the crystallization pathway and the initial structural entities formed during gel formation. Pair distribution function analysis reveals structural differences in the intermediate amorphous structures, which preferentially crystallize into either BiFeO3 or Bi2Fe4O9. This study offers mechanistic insights into the formation process and synthetic guidance for controlled synthesis of BiFeO₃ and Bi₂Fe₄O₉ nanomaterials. Additionally, it elucidates the unusual growth behavior and structural size-dependence of Bi₂Fe₄O₉, particularly highlighting significant distortions in the local structure likely induced by the proximity of Bi's stereoactive lone electron pairs at small sizes.
Nuclear quantum effects and the Grotthuss mechanism dictate the pH of liquid water
Authors: Dasgupta Saswata , Cassone Giuseppe , Paesani Francesco
Published: June 2024

Water’s ability to autoionize into hydronium (H3O+) and hydroxide (OH−) ions dictates the acidity or basicity of aqueous solutions, influencing the reaction pathways of many chemical and biochemical processes. In this study, we determine the molecular mechanisms of the autoionization process by leveraging both the computational efficiency of a deep neural network potential trained on highly accurate data calculated within density-corrected density functional theory and the ability of enhanced sampling techniques to ensure a comprehensive exploration of the underlying multidimensional free- energy landscape. By properly accounting for nuclear quantum effects, our simulations provide an accurate estimate of autoionization constant of liquid water (Kw = 1.23 × 10−14 ), offering the first realistic molecular-level picture of the autoionization process and emphasizing its quantum-mechanical nature. Importantly, our simulations highlight the central role played by the Grotthuss mechanism in stabilizing solvent-separated ion pair configurations, revealing its profound impact on acid/base equilibria in aqueous environments.

Voices of resilience: A qualitative exploration of blogging as a resilience intervention among young people in the philippines
Authors: Dennis Relojo-Howell , Mark Hoelterhoff , Laura Cariola
Published: June 2024

Psychological resilience has been a topic of ongoing debate in the field of psychology, with a lack of consensus on its definition, operationalisation, and conceptualisation. Meanwhile, young people have been called upon to demonstrate resilience during the COVID-19 pandemic, particularly in Low- and Middle-Income Countries (LAMICs) where they have been disproportionately affected by the economic fallout. In response to this, this study aimed to explore the perception of resilience and blogging among young people from a LAMIC. Using in-depth interviews with 15 participants, the study identified three main themes: sources of resilience, role of resilience, and process of resilience. Additionally, five main themes related to blogging were identified: what is a blog, video bloggers, advantages, concerns, and experience. The study's findings highlight the importance of understanding resilience from a different demographic, which can influence the development of resilience interventions. This study also provides insights into the potential of using blogging as a tool for promoting resilience in young people. Overall, this study offers a valuable contribution to the understanding of resilience and its relation to digital mental health, particularly in diverse and underrepresented communities.

Obesity is associated with increased betatrophin levels, which can lead to fat metabolism disorders. Increased levels of betatrophin may inhibit the performance of the lipoprotein lipase (LPL) enzyme, making it difficult for triglycerides (TG) in the blood to be converted into energy and causing excessive fat accumulation in adipose tissue. Physical exercise has been reported to increase energy expenditure in obesity. This study aims to determine changes in betatrophin in obese women after moderate-intensity aerobic exercise. A total of twenty obese women aged 20-30 years took part in the study. The participants were administered into two groups: control (K1) and moderate-intensity aerobic exercise (K2). Moderate-intensity aerobic exercise (60-70% HRmax) was performed five times a week for two weeks. Pretest and posttest betatrophin levels were measured using the Enzyme-Linked Immunosorbent Assay (ELISA) Kit method. Data were analyzed using a paired samples t-test with a significance level of p ≤ 0.05. The results showed the average pretest and posttest betatrophin levels in K1 (0.44±0.14 vs 0.44±0.13 ng/mL; p=0.894), and K2 (0.41±0.05 vs 0.31±0.03 ng/mL; p=0.000). According to the study's findings, moderate-intensity aerobic exercise (60-70% HRmax) performed five times per week for two weeks positively impacted alterations in betatrophin levels in obese women.

The number of open spaces and the population aged seven years and above are known to determine the ratio of open spaces to the Sports Development Index. This study used a survey method with a quantitative descriptive approach, using sports open spaces as research variables. The sampling technique was based on the Sports Development Index (SDI), namely the Multistage Random Sampling. The population of this study was residents of Tawangharjo Village, Tarub Village, and Godan Village. The availability of open sports spaces in the Tawangharjo sub-district, represented by 3 villages, namely Tawangharjo, Tarub, and Godan, is in a low category. The solution is to improve sports development in the open space aspect, namely by involving the government to improve the welfare of the people, such as by providing the most superior sports facilities in the region, including football, volleyball, martial arts, and jogging tracks. The role of the community can help develop sports development, such as cooperation in cleaning abandoned sports open spaces.

Published: June 2024

Muscle overuse during exercise increases the risk of muscle injury. L-citrulline, one of the ergogenic substances highly found in watermelon, is frequently used to reduce muscle soreness. This study aimed to compare the effects of pure L-citrulline and watermelon juice in reducing delayed-onset muscle soreness (DOMS) and muscle damage using uric acid as a marker for inflammation. A single-blind controlled trial was employed among 33 participants selected with a purposive sampling method. The participants were given either a mineral water drink containing 1.2 g of L-citrulline supplementation, 750 ml of watermelon juice, or a bottle of mineral water as a placebo administered 2-h before exercise. A multiple-sprint with a deceleration phase was used to induce DOMS. There was a significant decrease of DOMS 12 h and 24 h post-exercise with watermelon juice and pure L-citrulline (p=0.001). However, there was no significant difference in effectiveness between both forms of supplementation (p = 0.748). There were no significant changes in uric acid levels post-exercise with both forms of supplementation. Both watermelon juice and pure L-citrulline show similar effectiveness in improving subjective feelings of DOMS but fail to provide evidence of their ability to reduce muscle inflammation significantly via the reduction of uric acid levels.
COMPUTATIONAL TOOLS FOR THE DNA TEXT COMPLEXITY ESTIMATES FOR MICROBIAL GENOMES STRUCTURE ANALYSIS
Authors: Mitina A. , Orlova N. , Dergilev A. , Orlov Yuriy
Published: June 2024

One of the fundamental tasks in bioinformatics involves searching for repeats, which are statistically heterogeneous segments within DNA sequences and complete genomes of microorganisms. Theoretical approaches to analyzing the complexity of macromolecule sequences (DNA, RNA, and proteins) were established prior to the availability of complete genomic sequences. These approaches have experienced a resurgence due to the proliferation of mass parallel sequencing technologies and the exponential growth of accessible data. This article explores contemporary computer methods and existing programs designed to assess DNA text complexity as well as construct profiles of properties for analysing the genomic structures of microorganisms. The article offers a comprehensive overview of available online programs designed for detecting and visualising repeats within genetic text. Furthermore, the paper introduces a novel computer-based implementation of a method to evaluate the linguistic complexity of text and its compression using Lempel-Ziv. This approach aims to identify structural features and anomalies within the genomes of microorganisms. The article also provides examples of profiles generated through the analysis of text complexity. Application of these complexity estimates in the analysis of genome sequences, such as those of the SARS-CoV-2 coronavirus and the Mumps Orthorubulavirus, is discussed. Specific areas of low complexity within the genetic text have been successfully identified in this research.
VIBRONIC SPECTRA OF OXAZINE 750 DYE IN AQUEOUS MEDIA: A COMPUTATIONAL STUDY
Authors: Leontieva S.
Published: June 2024

The MN12SX/6-31++G(d,p)/SMD theory level exactly reproduced both positions of the main maximum and short-wavelength shoulder of OX750 absorption in an aqueous solution. The optimal functional for calculating the vibronic absorption spectra of different oxazine dyes in an aqueous solution was discussed based on the author’s present and previous studies. The absorption spectrum shoulder is caused by the vibronic transition. The vibrations involved in vibronic transitions correspond to large-scale molecular movements, are low-frequency, and very weak compared to the others. However, excitation significantly influences the vibrations including the most intensive ones. Photoinduced charge redistribution is local and there is no charge transfer over the dye molecule as a whole. Aliphatic hydrogen atoms prevent water molecules from accessing the N24 nitrogen atom. Considering H-bonded "solute-solvent" interactions by three water molecules led to a redshift of the entire spectrum by ≈15 nm.
A strengthening of H-bonds with water molecules upon OX750 excitation was found, which explains this bathochromic effect. The intensity of low-frequency vibrations (including those involved in vibronic transitions) increases with the addition of bound water molecules, especially in an excited state. The vibration of the N-H bond of the imino group is strengthened (especially in an excited state) due to water molecule binding. Noticeable polarization of one water molecule bounded was revealed upon dye excitation. The vibronic model was also applied to calculate the emission spectrum of OX750 in the aqueous media.

The relevance of the problem. The widespread and uncontrolled use of antibacterial drugs not only in medicine, but also in agriculture, animal husbandry, and the food industry has led to the spread of multi-resistant strains resistant to the most common antibacterial drugs. In search of alternative strategies for the prevention and control of bacterial infection, attention is increasingly being paid to bacteriophage (phage) therapy. With a wide range of genetic engineering capabilities, these bacterial viruses can be modified to achieve precise control and detection of bacteria and thus serve as a new source of antimicrobial agents. In addition to being used in antimicrobial therapy, phages can also be used as transport systems for drug delivery, as vaccines, or can be used for nanosembly of new materials, since phages themselves, their fragments and components are nanoobjects and functioning nanomachines, the assembly process of which is extremely relevant. The purpose of this article is: to analyze and summarize the most important information on the topic of bacteriophages, methods of their determination and effective transformation in modern science, to evaluate the achievements of modern research in the process of assembling heads (capsids) and laying intracapsid DNA in caudate bacteriophages (phage lambda and phage T4), the production of genetically modified phages and a review of the main prospects for the development of this direction.

Authors: Niveditha C  , Veena B M  , Shweatha H E
Published: June 2024

Background: The excess generated by the fruit processing industry, including peels, seeds, and residue, holds significant nutritional and industrial value. These components are rich in essential nutrients like carbohydrates, vitamins, minerals, and beneficial phytochemicals such as phytosterols, carotenoids, polyphenols, and fiber. These nutrients provide various health benefits, including antioxidant, anti-cancer, and anti-inflammatory properties, as well as supporting gut health. Despite being considered a waste, they present an excellent opportunity for food scientists and nutritionists to innovate, creating ways to boost the nutritional content of food products or even develop entirely new food items. Objective: Therefore, the current research was designed to harness the potential of cashew apples in creating sustainable value-based products. Material and Methods: Three products viz., squash, jam, and cashew leather were developed with varying percentages of cashew apples (CA) mixed with orange (O) and pineapple (P) fruit. Sensory analysis was done using the descriptive method and the most acceptable product was analysed for moisture, ash, Vit C, iron, and Phosphorus using established protocols. Results: Moisture content of jam (OJ1 made with CA75% + Orange 25% and fruit leather (FLO2 made with CA 50% + orange 50%) was 30.25% and 7.9% respectively. Ash depicts the inorganic content that is representative of minerals. The ash content of jam (OJ1 made with CA75% + Orange 25%) and fruit leather (FLO2 made with CA 50% + orange 50%) was 3.96 and 1.06%. Conclusion: Thus, by processing and using by-products of fruit processing into nutritious food products, one can enhance food and nutrition security.

Temporal variations in storage conditions of the post-collapse rhyolites, Valles Caldera, New Mexico (USA)
Authors: Grismer Magdalen , Waters Laura
Published: June 2024

We present a petrologic study of the post-collapse rhyolites from Valles Caldera (New Mexico, USA) to evaluate changes in magmatic storage conditions following the eruption of the Upper Bandelier Tuff (UBT). We assess likely phenocrysts through textures, comparison with experiments, and rhyolite-MELTS outputs, and apply thermobarometers, oxygen barometers, and hygrometers to these minerals. The post-collapse rhyolites have average pre-eruptive temperatures ranging from 742–824 °C, average pre-eruptive oxygen fugacities ranging from –0.1 to +1.3 ΔNNO, and average pre-eruptive H2O contents ranging from 4.4–6.0 wt% H2O. Average storage pressures range from 130–196 MPa for all rhyolites except the youngest, which has a range of 157–376 MPa. The post-collapse rhyolites are more oxidizing than the UBT and have similar pre-eruptive pressures. The change in oxidation state between the rhyolites and UBT, despite similar storage pressures, can be explained if the UBT is generated from a unique, reduced source but accumulated at depths similar to the post-collapse rhyolites.

Published: June 2024

Public interest in reading is a major problem nationally and globally. One of the obstacles to the progress of a nation can be judged by the habits of its people in terms of reading. Reading is an important part of life. The Archives and Libraries Office of Sukabumi District continues to encourage the growth of interest in reading in the community by implementing programs and improving services to meet the needs of users. This research uses one variable (1), namely the service management variable, with A.S. Moenir's service management theory (2006: 88–119), which consists of indicators of awareness, rules, organization, income, skills and abilities, and service facilities. This study uses a qualitative method with a narrative approach. The results showed that the Sukabumi District Archives and Libraries Service had made significant efforts to manage quality services. They provide easy access to relevant information and libraries by facilitating the needs of the user. This service includes programs that support the improvement of human resources and collections of books, magazines, journals, and other media that are well managed and available to the public and visitors.
THE ASSESSING THE DISTRIBUTIONAL IMPLICATION OF VAT EXEMPTIONS OF EDUCATION AND HEALTH SECTORS
Authors: Puspitasari Marycha , Nasrudin Rus'an
Published: June 2024

The tax revenues are still the primary state revenue sources in Indonesia. With the declining trend of corporate taxes, the challenge of increasing other taxes becomes even more severe, including Value Added Tax (VAT). The main change in the VAT provisions in the Law on the Harmonization of Tax Regulations is broadening the VAT basis. Among others are education and health services. This study aims to determine the effect of that policy combined with hypothetical reform on spending. Using micro simulation method and Susana’s data for March 2019, this study estimates that the imposition of VAT increases poverty and reduces the relatively small income level for consumption. In general, it estimates that the imposition of VAT in Indonesia will increase poverty, although it can reduce inequality. When receiving cash transfers, poverty and inequality decreased relatively small. These results imply that the fiscal policy of providing direct cash transfers is moderately effective in reducing poverty but not inequality.
State, Trait, and Target Parameters Associated with Accuracy in Two Online Tests of Precognitive Remote Viewing
Authors: Mossbridge Julia , Cameron Kirsten , Boccuzzi Mark
Published: June 2024

Objective. To better characterize the relations between accuracy on precognitive remote viewing (PRV) tasks and potentially relevant trait, state, and target parameters, we gathered PRV data in two online experiments and examined accuracy relative to: sex-at-birth, gender, age, anxiety, unconditional love, and target interestingness. Method. In experiment 1 we used a forced-choice, uncontrolled-time, self-judged PRV task for which 682 unpaid participants contributed a total of 5,432 trials. Experiment 2 used a free-response, controlled-time, independently judged PRV task for which 307 paid participants each contributed a single trial. In neither case were the participants pre-screened for precognition ability. Results. In experiment 1 (forced-choice PRV task), there was no significant target precognition and no effect of age on PRV performance, but we found a complex effect of sex-at-birth. We also found that targets most likely to be correctly predicted were also more likely to be judged as interesting compared to targets most likely to be incorrectly predicted; a pre-registered analysis confirmed this effect. In experiment 2 (free-response PRV task) we found significant target precognition, no effect of age on performance, and a weak and indirect effect of gender. Feelings of unconditional love and anxiety were both correlated with higher accuracy in experiment 2. Again, target interestingness was positively related to accuracy. Conclusion. These results suggest that accuracy on PRV tasks is related to the emotional state of participants and target interestingness, and that task characteristics mitigate overall performance. We provide recommendations for future research based on these observations.

Stages of the political and legal unification of the Grand Duchy of Lithuania and the Crown of Poland in the “Course of Russian History” by E.F. Shmurlo
Authors: Kudryavtseva Regina-­Elizaveta , Samylovskaya Ekaterina
Published: June 2024

The paper is devoted to the analysis of Evgeny Frantsevich Shmurlo's views on the process of political and legal formation of the Polish-Lithuanian Commonwealth. The research is based on the analysis of pre-revolutionary and modern Russian historiography, as well as the fundamental work of the historian “The Course of Russian History”. As a result, the authors conclude that E.F. Shmurlo's actual presentation of the material is based on the concepts of historians from the pre-revolutionary school, especially M.K. Lyubavskiy, while the events assessments are largely based on M.O. Koyalovich's concepts and approaches. The authors of the paper note that the interpretation of the events related to the Grand Duchy of Lithuania and the Crown of Poland's unification is expressed in the term by which the researcher designates this process, namely “incorporation”.
Evaluation of the investment component of the cost of products and the problem of stimulating investment activity
Authors: Dobrova Katrina , Chebotarev Stanislav
Published: June 2024

Stimulating and supporting investment activity is a necessary condition for a successful industrial policy. One of the conditions for its provision can be considered the availability of methods that make it possible to clearly assess the expected value and profitability of the products produced, especially in terms of assessing the investment component of this value. But in practice, often an inadequate assessment of the investment component of the cost of products is one of the most significant factors inhibiting investment in real production. The article is devoted to the issue of assessing the investment component of the cost of products using modern approaches of investment analysis.
Phonetic transcription system of Quranic text: new opportunities and prospects
Authors: Karadagli Vugar
Published: June 2024

The present study aims to develop a phonetic transcription system based on the Azerbaijani Latin alphabet that can convey the sound of the text of the Quran as closely as possible. The language of the Quran, its sound system has a specific rigor and peculiarity of sound, developed for the text of the modern Arabic literary language, various transcription systems do not provide the transmission of the fullness and variety of shades of the sounds of the Quran, do not meet the requirements of the text of the Quran. The absence of a phonetic transcription system for the text of the Quran leads to a noticeable discrepancy in the transmission of the verses. Developed on the basis of the Azerbaijani Latin alphabet, this system is quite suitable for use outside of Azerbaijan.

Today, the task of forecasting the country’s foreign economic activity is relevant and important. Foreign trade is one of the key strategies of the Russian Federation to maintain a stable economy. Taking into account the new political prohibitions and the imposition of sanctions, it is necessary to learn how to accurately and quickly make forecasts for making informed decisions. Within the framework of this work, an ensemble of models for forecasting indicators of foreign economic activity of Russia, implemented within the framework of a large country model, is presented. The basic mathematical apparatus of the presented model includes methods of multiple linear regression and regression decision trees (CART), which together make it possible to obtain more accurate and high-quality results. The research was carried out using the information and analytical system “Horizon”.
