“We help people change harmful norms”: Working with key opinion leaders to influence MNCH+N behaviors in Nigeria
Authors: Adetunji Adetayo , Etim Eno-Obong E. , Adediran Mayokun , Bazzano Alessandra N. 
Published: August 2024

Background
Nigeria’s Maternal, newborn, and child health and nutrition (MNCH+N) outcomes rank among the world’s poorest. Engaging traditional and religious leaders shows promise in promoting related behaviors. The Breakthrough ACTION/Nigeria project worked with leaders in northern Nigeria to implement the Advocacy Core Group (ACG) model, a social and behavior change (SBC) approach aimed at influencing community norms and promoting uptake of MNCH+N behaviors. Qualitative assessment of the model contributes to evidence on SBC approaches for enhancing integrated health behaviors.

Methodology
This qualitative study was conducted in Nigeria’s Bauchi and Sokoto states in May 2021. It involved 51 in-depth interviews and 24 focus group discussions. The study was grounded in the social norms exploration (SNE) technique to examine normative factors influencing behavior change within the ACG model context. Data analysis used a reflexive thematic analysis approach. Ethical approvals were received from all involved institutions and informed consent was obtained from participants.

Results
The ACG model was vital in the uptake of MNCH+N behaviors. The influence of ACG members varied geographically with greater impact observed in Sokoto State. Normative barriers to improving MNCH+N outcomes included perceived religious conflicts with family planning, preference for traditional care in pregnancy, misinformation on exclusive breastfeeding (EBF), and gender-based violence resulting from women’s decision-making. The study demonstrated positive progress in norm shifting, but EBF and GBV norms showed slower changes. Broader challenges within the health system, such as inadequate services, negative attitudes of healthcare providers, and workforce shortages, hindered access to care.

Conclusion
The ACG model increased awareness of health issues and contributed to potential normative shifts. However, slower changes were observed for EBF and GBV norms and broad health system challenges were reported. The model appears to be a promising strategy to further drive SBC for better health outcomes, especially where it is combined with supply-side interventions.
Association between dietary niacin intake and Helicobacter pylori seropositivity in US adults: A cross-sectional study
Authors: Chen Zeru , Wu Shixin , Chen Guangzhan , Guo Xuguang 
Published: August 2024

Objectives
This study delves into the association between dietary niacin intake and Helicobacter pylori seropositivity, a topic gaining prominence in academic discourse. However, the precise role of Niacin in the development and progression of Helicobacter pylori seropositivity remains inadequately understood. Thus, this research aims to investigate the connections between H. pylori seropositivity and dietary niacin intake using a nationally representative sample of adults.

Methods
A cross-sectional analysis encompassed 4,000 participants from the National Health and Nutrition Examination Survey (NHANES) conducted in the United States between 1999 and 2000, all aged 20 years or older. The study employed the generalized additive model (GAM) and multivariate logistic regression to explore the potential relationship between niacin intake and Helicobacter pylori seropositivity. Subgroup analyses were performed based on gender, age, diabetes, hypertension, and hyperlipemia.

Results
Analyzing cross-sectional data from NHANES 1999–2000 involving individuals aged 20 years and above revealed that out of 4,000 participants, 1,842 tested positive for H. pylori via serology. Multivariate analyses unveiled a significant inverse correlation between niacin intake and H. pylori seropositivity. Adjusted odds ratios (ORs) for dietary niacin intake in quartiles Q2 (13.31–19.26 mg/d), Q3 (19.27–27.42 mg/d), and Q4 (>27.42 mg/d) compared to Q1 (<13.31 mg/d) were 0.83 (95% CI: 0.69–1.01), 0.74 (95% CI: 0.61–0.90), and 0.66 (95% CI: 0.54–0.81), respectively. Moreover, a nonlinear L-shaped relationship (P = 0.022) emerged between niacin intake and H. pylori seropositivity, indicating minimal risk of H. pylori infection at approximately 44.69 mg of niacin per day in the diet.

Conclusion
This study suggests a potential link between increased dietary niacin intake and reduced prevalence of Helicobacter pylori seropositivity. This correlation is bolstered by plausible mechanisms involving immunomodulatory function, mitochondrial dysfunction, and cellular oxidative stress.
Occupational stress and associated factors among clinical nurses caring for COVID-19 patients in a Vietnamese tertiary hospital
Authors: Vu Phu Dinh , Nguyen Thuong Thi , Le Duyet Van 
Published: August 2024

Background
Nursing professional is one of the most stressful jobs, particularly during the COVID-19 pandemic. When caring for COVID-19 patients, nurses face challenging conditions and limited resources, as well as the fear of infecting themselves and their families, putting them at risk for depression, anxiety, and insomnia. The purpose of this study was to determine the frequency, sources, and risk factors for occupational stress among clinical nurses caring for COVID-19 patients in a Vietnamese tertiary hospital.

Methods
A cross-sectional survey was conducted among all clinical nurses (184 nurses) at a tertiary hospital in Vietnam from March 15 to April 15, 2021. A questionnaire was used for collecting data. Data analysis was done by descriptive statistics, bivariate and multivariate logistic regressions. Risk factors were identified by adjusted odds ratio with 95% confidence interval and P values less than 0.05.

Results
The survey was completed by 89.7% (165/184) of clinical nurses. Most participants were female (85.5%) and ≤ 40 years old (97.6%). Overall, participants reported a medium stress level with an Extended Nursing Stress Scale (ENSS) mean score of 1.79 points, and 32.1% had occupational stress. Prevalence of occupational stress among participants caring for COVID-19 patients (34.0%) was not statistically significant difference with that among those who did not (29.4%). Nurses’ occupational stress in emergency and intensive care units (50.0%) was substantially higher than that in the other departments (11.7%). The most stressors for participants were difficulties connected to inadequate emotional preparedness, patients and families, and death and dying, with subscale mean scores of 1.97, 1.88, and 1.88 points, respectively. In multivariate analysis, working at an emergency and intensive care unit (OR 4.97), usually or more frequently feeling heavy duty for patients (OR 3.17), and income decrease (OR 3.03) were risk factors associated with occupational stress.

Conclusion
One-third of clinical nurses at a tertiary hospital experienced occupational stress, with highest rate occurred at emergency and intensive care units. Nurses’ working conditions at emergency and intensive care units should be essentially addressed to improve nurses’ occupational stress.

Published: August 2024

This research models the spread of Covid-19 by developing the model. In this model there are seven compartments, namely the susceptible subpopulation (S), the subpopulation that has received the first dose of vaccine (V1), the subpopulation that has received the second dose of vaccine (V2), the subpopulation that has received the third dose of vaccine (V3), the exposed subpopulation (E), infected subpopulation (I), and recovered subpopulation (R). From the model that has been formed, a search for disease-free and endemic equilibrium points is carried out, then looking for the basic reproduction number (R0) as a benchmark for the presence or absence of the spread of Covid-19 in a population, then numerically simulating it using the Matlab R2017a software. The results of this numerical simulation are in accordance with the dynamic analysis carried out, namely if the condition is then Covid-19 cannot spread, whereas if the condition is then Covid-19 can spread in a certain area. In addition, the disease cannot spread quickly if the proportion of those who are vaccinated is increased, so that the use of vaccines can be used as an effort to prevent the spread of Covid-19.
An improved supply of anthocyanin dye for creation of effective dye-sensitized solar cells grounded on natural dyes
Authors: Patni Neha 
Published: August 2024

Abstract
In order to advance the power conversion efficiency of dye-sensitized solar cells, this article shows the selection of better sources of the sensitizer anthocyanin. The cells were created by combining liquid and solid electrolytes, adding natural dye, and employing a photo anode of aluminium-doped zinc oxide and a counter electrode of fluorine-doped tin oxide. Light harvesting efficiency, scanning electron microscopy, ultraviolet and infrared spectroscopy, and other methods were used to characterise the cells. From all the combinations made utilising different sources, the cell based on the D1 dye sample from Hibiscus sabdariffa L. (Manipur) had the best efficiency at 1.58 %. An effective DSSC was the end result of this strategy for identifying the optimal extraction source for anthocyanin natural dyes.

Published: August 2024

Abstract
To address the challenges of difficulty and low penetration speed of aqueous deacidification agents in paper, we aimed to enhance the wetting performance of these agents by incorporating a surfactant. We selected four surfactants for our study: anionic sodium dodecyl benzene sulfonate (SDBS), cationic cetyltrimethylammonium bromide (CTAB), nonionic polysorbate-80 (TW80), and polyether-modified trisiloxane (TRSE). The wetting properties of these surfactants on sodium propionate aqueous deacidification agent, the alkali stability of the solution, and the effects of moist heat aging on paper durability were explored. The results demonstrated that TRSE exhibited superior performance compared to the other three surfactants, effectively reducing the surface tension of sodium propionate solution to 21.02 mN/m. In alkaline conditions with a pH range of 8.00–10.00, the surface tension of SDBS, CTAB, and TW80 solutions remained stable for 30 days. Similarly, under weakly alkaline conditions with a pH value below 9, the surface tension of TRSE solutions exhibited stability. It should be noted that SDBS accelerated the decline of paper tensile index and whiteness during the heat and humidity aging process; at the same time, CTAB, TW80, and TRSE had no noticeable adverse effects on paper aging resistance.

Abstract
The present study scrutinizes the significance of heat source/sink (HSS), thermophoretic particle deposition, and porous media on the time-dependent ternary nanofluid stream across a stretchable surface in the presence of Newtonian heating (NH) and common wall temperature (CWT) cases. The governing equations of the investigated model are changed into ordinary differential equations by using suitable similarity transformations. The resultant dimensionless equations are solved using the Laguerre polynomial collocation method. For comparison, the Runge Kutta Fehlberg’s fourth-fifth order (RKF-45) method is employed. Graphs are used to illustrate the significant parameters’ impacts on each profile, and relevant physical quantities such as the Sherwood number, skin friction, and Nusselt number are exhibited. The study reveals that the velocity profile drops with an increase in permeable parameters. The thermal profile increases with improvement in porous and HSS constraints. The concentration diminishes as the value of the thermophoretic parameter rises. For better solid volume fraction values, the rate of temperature dispersal is lower in the NH case associated with the CWT case. Additionally, the rate of thermal distribution is enhanced by approximately 2.90% surface drag force, 4.73% in the CWT case and 2.27% in the NH case, and the rate of mass transfer is enhanced by 2.99% when transitioning from ternary the ternary hybrid nanofluid to the (normal) nanofluid. The results of the study will help in heat exchangers, thermal management, chemical engineering, biomedical instruments, and design and optimization of electronic equipment.
The Basic Dualism in the World: Object-Oriented Ontology and Systems Theory
Authors: Zwick Martin 
Published: August 2024

Abstract
Graham Harman writes that the “basic dualism in the world lies…between things in their intimate reality and things as confronted by other things.” However, dualism implies irreconcilable difference; what Harman points to is better expressed as a dyad, where the two components imply one another and interact. This article shows that systems theory has long asserted the fundamental character of Harman’s dyad, expressing it as the union of internal structure and external function, which correspond exactly to what Levi Bryant, characterizing Harman’s views, refers to as the intra-ontic and the inter-ontic, respectively. After interpreting Harman’s dyad in terms of the ontology of systems theory, the article illustrates his dyad with a variety of examples, including conceptions about truth, ethics, value, and intelligence. The structure–function dyad is a spatial conception of a system as an object. It is usefully augmented with a temporal dimension, expressed in a third component or with an additional orthogonal dyad. Adding a temporal dyad to the structure–function dyad joins the idea of an event and/or process to the idea of an object.

Published: August 2024

Abstract
A novel hydrophobic association copolymer (PAMA) was synthesized by incorporating acrylamide (AM), 2-acrylamide-2-methylpropanesulfonic acid (AMPS), cationic monomer (MEDDA), and methyl methacrylate (MMA). The properties of MMA copolymers with varying contents were analyzed using infrared spectroscopy, nuclear magnetic resonance spectroscopy, and scanning electron microscopy. Optimal overall performance of the solution was achieved when the MMA content reached 1.4 % w/w. Compared to pure PAAM (without MMA), the PAMA-1.4 % polymer exhibited superior viscoelasticity, temperature resistance, and shear resistance. This enhancement in PAMA performance can be attributed to the significant inhibition of intermolecular water film formation within the polymer matrix by MMA, effectively improving and regulating solution solubility while strengthening molecular chain interactions and enhancing the structural network strength of PAMA polymers. Additionally, the inclusion of MMA transformed rock surfaces from non-wetting to wetting conditions, thereby greatly improving oil displacement efficiency. In displacement experiments, PAMA-1.4 % performed better in terms of enhanced oil recovery, the recovery rate of 0.1 % w/w PAMA-2.4 % solution is only 7.78 %, while the recovery rate of 0.1 % w/w PAMA-1.4 % solution is 13.06 %.

Сопоставление данных спутниковых измерений с результатами измерений с помощью других средств – важнейшая и необходимая составляющая валидации спутниковых данных. В настоящей работе сопоставлены результаты спектрометрических измерений содержания NO2в атмосфере с помощью спутникового прибора OMI(Ozone Monitoring Instrument) в 2004–2020 гг. с данными наземных сумеречных зенитных измерений на 14 станциях сети по обнаружению изменений состава атмосферы (Network for the Detection of Atmospheric Composition Change– NDACC). Получены широтные распределения содержания NO2 и характеристик сопоставления: разности содержаний, коэффициентов корреляции и линейной регрессии между спутниковыми и наземными данными. Предложены критерии поверки межгодовых и долговременных изменений содержания NO2по данным OMIна основе результатов наземных измерений. Выявлены широтные – полушарные и региональные – особенности соответствия между спутниковыми и наземными данными. Получена существенно новая информация о зависимости характеристик сопоставления от уровня загрязнения нижней тропосферы окислами азота, а также временного масштаба вариаций NO2: межсуточного, сезонного и межгодового. Результаты будут полезны при анализе изменчивости NO2по данным OMI.
Comparison of results of satellite measurements by results of independent measurements is an esencial and necessary component of validation of satellite data, justifying their use for scientific and practical tasks. The work compares the results of spectrometric measurements of the NO2content in the atmosphere by the Ozone Monitoring Instrument (OMI) in 2004–2020 with the results of ground-based twilight zenith measurements at 14 stations of the Network for the Detection of Atmospheric Composition Change (NDACC). Latitudinal distributions of quantitative characteristics of the comparison have been obtained, including the NO2contents, their differences, and correlation and linear regression coefficients between the satellite and ground-based data. Criteria for validation of interannual and long-term changes in NO2derived from the OMI data with the help of ground-based measurements are proposed. The latitudinal – hemispheric and regional – features of the correspondence between the satellite and ground-based data have been revealed. Significantly new results have been obtained on the dependence of the comparison characteristics on the level of pollution of the lower troposphere with nitrogen oxides and on the time scale of NO2variations: day-to-day, seasonal and interannual. The results will be useful in analysis of NO2variability based on OMI data. The continuation of this work may be a comparison of the results of the analysis of interannual variations and long-term NO2trends obtained on the basis of the OMI and ground-based measurement data.
Central-Asian Cotton as a Missed Strategic Resource for the Production of Smokeless Gunpowder in Russia in the Late 19th – Early 20th Centuries
Authors: Сергиевский Илья 
Published: August 2024

The most important military-strategic resource to this day is gunpowder, the basis for the production of which is cotton. Due to the difficult geopolitical situation, as well as global climate change, attempts to replace it with other types of raw materials of domestic origin do not stop. In this publication, we would like to refer to the experience of the past, because in the late 19th — early 20th centuries the Russian Empire was forced to face similar problems. The country faced a similar dilemma — to use foreign-made cotton or to develop its own raw material base in Central Asia. The realization of this goal was achieved through the use of previously unpublished archival materials from the Russian State Historical Archive, the Russian State Military Historical Archive, the Russian State Military Archive, the State Archive of the Tambov Region, the scientific archive of the Military Historical Museum of Artillery, Engineering and Communications Troops. Historical-genetic and systemic methods were used to prepare the publication. Mathematical and statistical methods were used as auxiliary research methods. Thanks to this, it was possible to fully recreate the picture of various origins cotton use for the production of gunpowder in Russia in the late 19th — early 20th centuries. The historiography of the problem under consideration is characterized. The key factors influencing the use of foreign raw materials in the production of gunpowder in the Russian Empire have been identified. Repeated attempts have been made to use Central-Asian cotton for these purposes. The results of the work of the domestic powder industry during the First World War (1914—1918), as well as the main difficulties associated with providing it with cotton of both foreign and Russian origin are considered. Thanks to the appeal to historical experience, it was established that Russian bureaucracy and inertia were negatively manifested when trying to use domestic cotton for the production of smokeless gunpowder; it was revealed that at a critical moment foreign supplies may stop, which emphasizes the need to develop their own raw materials and production base; it is proved that the &quot;cotton problem&quot; has become one of those delay mines which led to failures at the front and the subsequent collapse of the Russian Empire.
