Published: July 2024

The efficient and promising solvent-free method, catalyzed by Sulphated Tin oxide (SO4 2-/SnO2), has been developed for the synthesis of 1,3,5-triarylbenzene and its derivatives. The Bronsted acidic surfactant catalyst facilitates quick results and high yields, offering additional advantages such as easy separation and reusability with almost the same efficiency for subsequent cycles. This protocol involves the self-condensation of three molecules through cyclotrimerization with high chemo-selectivity. The substrate methyl phenyl ketone contains both electronwithdrawing and electron-donating groups, which assemble the target moiety with high and low yields, respectively. The synthesized compounds are evaluated through in silico studies to assess their drug-likeness properties.

Environmental consequences of the creation and discharge of reservoirs in the steppe zone
Authors: Danilov-Danilyan V. I. , Novikova N. M. , Nazarenko O. G.
Published: July 2024

The article examines the environmental consequences of the construction and operation of reservoirs – the responses of aquatic and terrestrial ecosystems and their components to changes in the water regime. Such reactions depend on the surrounding landscape and are zonally specific. They are especially pronounced in the steppe zone. The authors systematized the consequences, natural and anthropogenic factors determining their evolution, measures to minimize negative environmental consequences that can be traced from the upper reaches of the reservoir to the reservoir – receiver of the river flow, where it is built. In particular, the decrease in bioproductivity and biodiversity caused the problem of reservoir drainage. As a result of lengthy discussions, an opinion has been formed that the descent of small reservoirs, which have lost their importance, as well as orphan ones, is currently environmentally justified. At the same time, it is necessary to carry out special hydro-reclamation and phytomeliorative measures aimed at stabilizing the hydrological and ecological situation.
Synergid activity of lysozyme and carnosine with antimicrobial drugs in relation to Klebsiella pneumoniae
Authors: Bukharin O. V. , Ivanova E. V. , Zdvizhkova I. A.
Published: July 2024

Klebsiella pneumoniae strains are opportunistic microorganisms that colonize the human gastrointestinal tract and can spread to various tissues and systems of the body, causing a wide range of severe diseases, including pneumonia. The problem of Klebsiella infections has become topical recently due to the spread of hypervirulent and antibiotic-resistant strains in the K. pneumoniae population, which indicated the need to develop modern antimicrobial agents. One of the approaches to combating pathogens of pneumonia is a combination of lysozyme with antimicrobial drugs, which was successfully tested in children’s hospitals in Orenburg. A natural antioxidant and antioxidant, carnosine, is considered as a new candidate in the fight against Klebsiella. A synergistic combination of carnosine with antimicrobial agents against Klebsiella pneumoniae was established in vitro. The results obtained allowed us to expand the range of effective and safe means of combating pathogens of Klebsiella infections.
On the usefulness of turning to the experience of the Warsaw Pact Organization
Authors: Trunov F. O.
Published: July 2024

At the beginning of the 2020s, the formation of a new world order became obvious. In parallel, there are two large-scale processes. One of them is a partial reformatting of connections within camps of Western democracies, the other is the emergence of a community of a number of states outside the West. The emergence of this commonality presupposes a noticeable increase in cooperation of the armed forces between interested players.
Here it becomes necessary to use experience of functioning of specialized structures without the participation of Western countries. Studying the experience allows us to take into account a number of schemes that have proved their effectiveness and usefulness, primarily developed under the auspices of the Warsaw Pact Organization. Their wasps thinking is becoming especially in demand in the context of a noticeable tightening of the Western approach to contain opponents – Russia, China, Iran.
The article points out the limited attention to the internal affairs of domestic historiography and political science, despite the obvious value of the experience of functioning of this organization. The author notes that a significant part of the gaps in the study of the strategy and practice of internal affairs can be filled by the fundamental work “Organization of the Warsaw Pact. 1955–1991. Story. Strategy. Policy”, prepared by a team of authors under the leadership of V.A. Zolotarev.
Refined simple model of stable water isotopic content in central Antarctic precipitation including Oxygen 17 fractionation
Authors: Ekaykin A. A.
Published: July 2024

Modeling the isotopic composition of atmospheric precipitation is an important tool for climatic, paleoclimatic and hydrological studies. This paper presents an improved simple model of the isotopic composition of precipitation in Central Antarctica. It differs from the previous version published by Salamatin et al. (2004) by 1) the included geochemical cycle of oxygen 17 and 2) the possibility of solving the inverse problem (i.e., finding the trajectory parameters that could form the isotopic composition of the precipitation observed at the end of the trajectory). The paper examines in detail the main tuning parameters of the model, among which the most important are the temperature and humidity in the moisture source, the “circulation parameter”, which takes into account the advection of vapor into the moisture source, the condensation temperature and the degree of air supersaturation with moisture in ice clouds. Based on the analysis of data on the isotopic composition (including “excess of oxygen 17”, 17O-xs) of water vapor in the surface layer of the atmosphere over the ocean and surface snow sampled along meridional profiles in East Antarctica, the optimal tuning of the model for calculating the isotopic composition of atmospheric precipitation at the Antarctic Vostok station was performed. In particular, it is shown that the temperature and humidity of the air in the moisture source are +17.4°C and 72%, respectively, and the condensation temperature is –41.3°C. The possibilities of using the model to analyze the isotopic composition of liquid precipitation falling on other continents are discussed. The final part of the paper discusses the limitations of the model. In particular, it is noted that the model does not take into account such processes as the evaporation of precipitation when it falls in arid conditions, mixing of trajectories, the influence of local sources of moisture, as well as the features of isotope fractionation during the evaporation of moisture from the continents.

La Organización Mundial de la Salud (OMS, 2015) en su informe mundial sobre el envejecimiento y la salud, publica que los adultos mayores son la población que más medicamentos consume en un mismo tiempo. Enfatiza que el ser humano, cuando llega a esta etapa del ciclo de vida, presenta mayores efectos adversos a los fármacos administrados, además de una tendencia al uso inapropiado de estos con la edad. El deterioro corporal del adulto mayor en este momento del curso de vida es innegable, por el déficit en el que entra el organismo para mantener las funciones más importantes; esto, por supuesto, predispone mucho más a padecer comorbilidades que aceleran el proceso de muerte o, en algunos casos, no tienen curación y requieren tratamientos prolongados y disciplinados.
Index Premium Trends Resulting from Composition Changes to the S&P 500 and Its Implications for Market Efficiency
Authors: Nie Dongfang
Published: July 2024

Transient price pressures immediately before the announcement events and afterward indicate that there is a violation of market efficiency.  This paper empirically investigates the state of the market efficiency by following a procedure outlined by Petajisto who looked at trends in index premium and cumulative abnormal returns from 1990 to 2005.  This paper provides an update on index premiums and its implications from 2004 to 2012. For additions and deletions to the S&P 500, we find that the cumulative abnormal return from announcement to effective day has averaged 3.98 % and -9.90%. The index premium has varied from 0.05% in 2011 to a peak of 36.2% in 2008, with an average of 4.5% from 2004 to 2012. We claim that index premium and Cumulative Abnormal Return for additions has decreased in the long run. We also claim that the deletions have a stronger impact on the index premium than the additions.

Authors: Setiadi Robertus , Danarsari Dwi Nastiti
Published: July 2024

Traditional business activities of commercial banks in Indonesia experienced a shift as indicated by the percentage of non- interest income per interest income from 26.1% in 2014 to 51.3% in 2020. The study aims to determine revenue diversification, internal determinants, and macroeconomic determinants in affecting profitability, stability, while also observing the role of bank capitalization. This study analyze sample of Conventional Commercial Banks in Indonesia from 2013 to 2020, using dynamic panel data GMM.  Research proves that direct effect of non-interest income on revenue diversification has a significant positive effect on ROA and risk adjusted ROA, as well as a negative effect on NPL; as the indirect effect of only significantly affects RAROA. However, there are contradictions in the results of research using the interaction variable of revenue diversification with bank capitalization. The empirical test results also prove the role of the control variables cost income ratio, deposit to total asset, bank capital, loan to total asset, bank size, inflation rate, and GDP growth in affecting bank performance and stability. This study proves the specific benefit of revenue diversification for commercial banks in Indonesia as a whole, although it does not apply to BUKU 1 banks.
Predicting Equity Crowdfunding Success
Authors: Bjornsen Matt , Borchers Sarah , Dority Bree , Hayes Suzanne
Published: July 2024

Equity crowdfunding has grown exponentially in the United States since the passage of the JOBS Act in 2013, yet it continues to be a research area that is relatively unexplored in the United States due to the limited availability of data. U.S equity crowdfunding campaigns are notoriously unsuccessful, and this paper develops a predictive model for equity crowdfunding success to determine whether the positivity of the language used, and the length of the campaign description influences an investor’s decision to invest. A model is developed on a balanced training set and applied to a test set, and the overall results are evaluated using a confusion matrix to determine the accuracy, precision, and recall of the model. Our overall results indicate that both the tone of sentiment and the length of the campaign description are predictive of an equity crowdfunding campaign’s success. Specifically, the potential investors appear to be attracted to positive campaign descriptions that are written with concise language.
Addressing the Black Maternal Mortality Rate
Authors: Sanders Kennedy ,   Rowan University, Venkataraman Venkataswar , Whelihan Kate
Published: July 2024

Introduction: As of 2021, the Black maternal mortality rate in the United States was 69.9 deaths per 100,000 live births as compared to the national average of 32.9 and the White American average of 26.61. It has been demonstrated that this discrepancy is not fully explained by socioeconomic status. Doulas are professionals who provide support and guidance throughout pregnancy, birth, and early parenthood. Encouraging the use of doulas may be an effective approach to improve the birth experience for Black mothers. Methods: A literature review was performed using PubMed and the following search strings: maternal mortality rate (+race, +race +ethnicity, +African Americans, +Doulas) and improving perinatal care (+race, +doulas). In addition to this search strategy, title and abstract searches were used. Systematic and narrative reviews, qualitative and quantitative primary publications were included. Publicly-available data from national organizations were also used. Extracted data were analyzed through IBM SPSS v29.0, GraphPad Prism v12.0 and/or functions in Excel for quantitative analyses. Thematic word searches were used for qualitative analyses. Results: Women supported by doulas are found to experience more respectful care, as opposed to women without doulas. This association is largest for non-Hispanic Black women. Doulas were found to positively impact perinatal outcomes during antepartum, labor and delivery, and postpartum periods. These impacts include: improved self-esteem, increased perceived social and clinical support, decreased cesarean rates, decreased rates of preterm birth and low birthweight, and increased infant safety practices. Conclusions: The support of doulas is associated with both objective and subjective improvements in birth outcomes, particularly for Black mothers. Surveys indicated that Black mothers benefited not only from their experience with doulas, but from the support they gained throughout their pregnancies and deliveries. This suggests that increased use of doulas by Black mothers may help address the racial disparities in maternal mortality and birth outcomes.

Big Data (BD) innovations have become the key differentiators in any competitive analyses, and has become/is, a lifestyle. Building on the Diffusion of Innovation theory, Technology Acceptance Models 1, 2, 3, and the International Requirements Engineering Boards’ (IREB) Requirements Engineering framework, this study aims to identify perceptions towards BD innovations, to design agile feature-based and rule-based intelligent systems, adaptable to progressive changes over time in the future. To reduce variable bias, random sampling of two overlapping demographics is carried out, over two time periods. The first case study, involves perceptions towards BD Innovations, blockchain, Augmented Reality/Virtual Reality/Mixed Reality. The second case study relates to perceptions towards intelligent assistants, e.g. Alexa. For the first case study, by triangulating correlation analyses, linear regression analyses, k-means and hierarchical agglomerative clustering (HAC) results, findings reveal different degrees of acceptance/caution among age groups and gender, and the influence of job prospects on perceptions. Furthermore, HAC’s profile means is more explanatory in terms of distribution and number of clusters, while k-means’ profile means is more positive than HAC’s. For the second case study, findings indicate that personality/dispositions, Technology Acceptance Model’s (TAM) adjustment and anchor, as well as interaction styles, may influence perceptions, more than gender or ability. Together, the two case studies provide age-progressive requirements analyses, and an opportunity tree. The fuzzy characterizations can be used in computational thinking design and matrix factorization in (fuzzy) rule-based design for seniors. However, sample size is small and thus, not generalizable.

Based on the Perspective of Breakthrough Innovation: A Study on the Impact of R&D Subsidies and Investment on Enterprises High Quality Development
Authors: Li Ya-ning
Published: July 2024

Based on the micro data of listed companies of specialized and new enterprises in 2017–2021 as a sample, the LP method is used to construct the total factor productivity index of enterprises to measure the high-quality development of enterprises. This research further examines the correlation between government R&D subsidies, enterprise R&D investment, and enterprise high quality development, and further confirms the mediating effect of breakthrough innovation. After a series of robustness tests, the conclusion that government R&D subsidies and investment significantly promote the development of enterprises of high quality remains valid. Further, based on heterogeneity, it is found that the central and western regions are better able to carry out high quality development when they receive R&D subsidies, while enterprise R&D investment works better in the eastern region to promote high quality development of enterprises. Testing of mechanisms reveals that breakthrough innovation has a considerable moderating influence between government R&D subsidies, enterprise R&D investment, and enterprise high-grade development. The conclusion suggests that in the period of digital transformation, the government’s increase in R&D subsidies for enterprises and enterprises’ increase in R&D investment can help enterprises carry out breakthrough innovation and realize high quality development.

Authors: Han Hao , Liu Xu , Hu Cuiping
Published: July 2024

The Roe format and LU-SGS method are used to discretize the NS equation, and the second-order precision unilateral differential discrete rigid body dynamic equations are coupled to solve the NS equation and the rigid body dynamics equations at Ma=0.2, and numerically simulate the 80°swept delta wing. In the rock history under different leading edge shapes, the influence of the leading edge shape on the rock characteristics of the delta wing is studied. The calculation model consists of three different leading edge shape delta wings with a lower sharpened, a sharpened tip and a double-sided sharpened tip. The results show that the shape of the leading edge significantly affects the bifurcation and amplitude characteristics of the delta wing rock. The taper angle of attack of the lower sharpened leading edge delta wing is the largest, and the splitting angle of the upper sharpened leading edge delta wing is the smallest. When the angle of attack is 25°, all three wings form equal-amplitude oscillations in the form of limit cycles. The amplitude of the lower sharpening leading edge delta wing is the smallest, and the amplitude of the upper sharpening leading edge delta wing is the largest; when the angle of attack increases At 30°, the three wings eventually form a constant-amplitude oscillation in the form of a limit ring, but the double-sided sharpened, upper-curved leading edge delta wing will flip and the other side will swing in equal amplitude.

Authors: Pisanenko D.A. ,   National Technical University of Ukraine ",   Igor Sikorsky Kyiv Polytechnic Institute"
Published: July 2024

N-Phenyl-, 1- and 2-naphthyl-N1-2- and 4-pyridylthioureas were synthesized via the reaction of phenyl-, 1- and 2-naphthylisothiocyanates with 2- and 4-aminopyridines, and the corresponding pyridine salts were prepared by benzylation of the latter. The anticorrosive properties of the synthesized compounds were studied by the gravimetric method in 3 M HCl at 800C using the 08 kp steel samples. The introduction of a benzyl fragment into the structure of N-aryl-N1-pyridylthioureas led to the emergence of a new adsorption ammonium center, which increased the overall anti-corrosion efficiency of the obtained compounds. When using N-aryl-N1-pyridylthioureas, the corrosion inhibition coefficient had the values of 4.5 to 59.0, whereas it increased to 90.8-629.0 for their salts. To explain the different anti-corrosion activity of N-aryl-N1-pyridylthioureas and their pyridine salts, quantum-chemical calculations of the energy parameters ЕНОМО, ЕLUMO and Е=ЕLUMO–EHOMO were carried out and the dependences of the corrosion inhibition coefficients on EHOMO and E, eE were obtained. A correlation was established between the inhibitory efficiency and energy parameters of the studied compounds.

Electric film heaters (EFHs) applied on flat steel substrates show promising potential in the production of heating devices. The basis for manufacturing EHFs is heat-resistant steel, the surface of which is coated with a heat-resistant electrical insulation coating. These coatings are glass crystalline and are applied mainly by screen printing. Compared to screen printing, the electrophoretic method of coating is more productive. In this work, glass in the MgO–CaO–B2O3–SiO2 oxide system was chosen for obtaining glass crystalline coatings. The paper provides a description of the material composition and the method used to prepare a suspension for еру electrophoretic deposition of coating. The main technological parameters for forming electrophoretic coatings with a specific thickness are determined based on experimental results. Utilizing calculated data on the properties of the selected glass, the study substantiates the most rational temperature and time regime for coating firing. These conditions promote crystallization and result in the production of heat-resistant coatings with sufficient electrical insulating properties for steel substrates of EFHs.

Porphyrins are a fundamental class of molecules involved in a multitude of biological and chemical functions ranging from photosynthesis in plants to biomarkers in medicine to optoelectronic devises. Despite the porphyrin molecule being such an important class of molecules known for centuries, its photophysics are surprisingly complex and models describing the spectroscopic behavior of porphyrins did not emerge until the 1950s. This review aims to distil the basics of porphyrin photophysics, describing how the Soret band and the Q band of the molecule are formed. In particular, a discussion of the four orbital theory and Hertzberg-Teller coupling will be conducted, both of which are necessary to understand the spectral properties of the porphyrin molecule. The review further aims to complement previous work discussing the chemical applications of hybrid light-matter states by discussing how the spectroscopic behavior of porphyrins is particularly useful in polariton chemistry.

For the first time, a chloroprene reagent (named as Z-1) has been used against corrosion in various aggressive environments under laboratory conditions. The corrosion protection properties of the reagent Z-1 have been studied in formation waters taken from oil wells No. 2646, 33151, 4012, 31193 and 33016 in operation at Balakhani Oil OGED. Samples made of Ct3 and P-105 brand steels with dimensions of 42155 mm have been used during the tests. Experiments have been performed under dynamic conditions at room temperature for six and twenty-four hours, and the corrosion rate has been determined by gravimetric method. During the experiments, concentrations of 10, 15, 20 and 25 mg/l of Z-1 composition were used. The analysis of results from numerous experiments conducted with both types of steel revealed that the optimal concentration of the composition is 25 mg/l. The protection efficiency of the composition Z-1 in the formation waters of the abovementioned oil wells during the six-hour experiment was as follows: for Ct3 samples, it ranged from 75% to 94%, 75% to 97%, 76% to 98%, 72% to 94%, and 68% to 87%, respectively, while for P-105 steel samples, it ranged from 76% to 96%, 72% to 92%, 73% to 85%, 70% to 90%, and 72% to 96%, respectively. During 24-hour corrosion tests, the protection efficiency of the composition Z-1 was 73–92%, 74–96%, 75–97%, 70–92%, and 66–85% for Ct3 steel samples and 75–94%, 70–91%, 72–83%, 68–89%, and 71–95% for P-105 steel samples, respectively.

Authors: Williams III John , Richardson Sonyia , Lewis Chance W. , Alexander Janae
Published: July 2024

School-level factors associated with Black students’ overrepresentation in school discipline outcomes (suspensions, expulsions, referrals to law enforcement, and arrests at school) operate to create a climate district-wide that reinforces educational trauma. This study aims to ascertain if school disciplinary risk influenced the suicide outcomes among high school Black boys and girls in seven urban school districts in the U.S. and to determine if the presence of student support personnel in the district influenced suicide outcomes. Results indicated that the risk of receiving an out-of-school suspension was positively associated with suicide outcomes for Black girls and the increase in student support personnel in the district negatively influenced Black girls' suicide outcomes. For Black boys, school support offered mixed associations. recommendations are provided to protect Black children from the school discipline-to-suicide pipeline. Ultimately, we hope to promote the social and emotional assets of Black children while protecting them from educational trauma.
Curriculum-Induced Trauma: Trauma-Informed Models and Schools as the Trauma Inducing Agent
Authors: Hancock Stephen , Richardson Sonyia C.
Published: July 2024

Curriculum-induced trauma (CIT) results from school socioracial adverse school experiences (SASEs) or traumatic stressors induced by curriculum supremacy towards whiteness, biased school policies, and culturally insensitive pedagogical practices. Given that schools can perpetrate school-induced trauma (SIT) and exist as trauma-inducing agents, it is imperative that trauma-informed models emphasize the trauma of racism, sexism, ableism, classism, religious and sexual orientation marginalization that are propagated by schools. This paper explores existing trauma-informed models and their ability to address the impact of SIT and CIT. Comprehensive innovative solutions are provided for creating school ecologies that are trauma-free and recommendations are suggested to teachers, administrators, and parents on how to support and combat CIT and SIT.
