Nutritional status is one of the most important determinants of immune response to infection. The aim of this study was to assess the levels of the concentration of the selected trace elements during and at the end of TB treatment. The serum concentration of some essential trace elements was assessed during therapy among patients attending Tuberculosis (TB) treatment centers in selected hospitals in Uyo, Akwa Ibom State, Nigeria. Written informed consent was obtained from the patients. Sputum samples were collected into wide mouth containers. This was repeated at two-month intervals for the period of six months for TB positive cases. Five millilitres of venous blood were collected into plain blood container and centrifuged at 3,000 rpm for 5 minutes at room temperature to separate sera. These were stored in the refrigerator at -200C until they were ready for analysis. Serum concentration of copper, zinc, iron, selenium and chromium were assessed by flame atomic absorption spectrometry method. A total of 155 persons participated in the study, 83 (53.5%) were females while 72 (46.5%) were males. Majority of the participants were in age group 31-50 years. The mean serum concentration of trace elements measured at different stages of TB treatment was statistically significant (p<0.05). The mean serum concentration of zinc, iron and selenium was significantly increased at 4th and 6th month of treatment compared to concentration at diagnosis and 2nd month of treatment. However, the mean serum concentration of copper and chromium significantly decreased at 6th month of treatment compared to concentration at initial diagnosis. The serum Cu/Zn ratio, Cu/Fe ratio and the Cu/Se ratio significantly increased at initial diagnosis, and significantly lower at 6th month of treatment (p<0.001). Assessment of the serum Zn, Fe, Cu, Se and Cr, and of the cu/Zn, Cu /Se and Cu /Fe ratio could serve as an indicator of the level of nutritional status and oxidative stress in tuberculosis patients. Findings from this study suggest a strong association of Zn, Fe, Cu, Se and Cr with TB before, during and after treatment. Therefore, measurements of trace elements can be used as tool to assess treatment indices during anti-tuberculosis therapy.
Some remarks on thermo-physical properties of magnetohydrodynamics heat and mass transfer of nano-fluid flow over a nonlinear permeable stretching sheet
Authors: Ekang I. F. , Popoola A. O.
Published: September 2024

The study aims to explore the potential benefits of investigating the MHD heat and mass transfer of nano-fluid over a nonlinear permeable stretching sheet. This is achieved by examining the influence of temperature- dependent viscosity and temperature-dependent thermal conductivity on nano-fluid. The governing partial differential equations that describe the nano-fluid flow are transformed and parameterized into a set of ordinary differential equations. These equations are subsequently solved numerically using shooting technique with the fourth order Runge-Kutta method. A graphical analysis is employed to assess the impact of specific fluid parameters on the momentum, thermal, and concentration equations. The outcomes depicted in the graphs reveal a noticeable effect of temperature- dependent viscosity and temperature-dependent thermal conductivity on the mathematical model.

Maize has been a major source of food consumed by people and animals but evaluation of radiological hazards due to consumption of the maize has not been carried out to ascertain any possible health hazards. At Essien Udim Local Government Area (LGA), the activity concentrations of radionuclides of 40K, 238U and 232Th and their transfer factors from soil to maize seeds and stems have been conducted using a gamma ray spectroscopy coupled with NaI detector. A total of 21 samples comprising 7 soil specimens, 7 maize seeds and 7 maize stems were collected and analysed. The mean activity concentrations of the radionuclides in the soil, maize seeds and maize stems samples are respectively 433.24 ± 5.65 Bq/kg, 367.61 ± 6.19 Bq/kg, 603.11 ± 8.04 Bq/kg for 40K, 12.66 ± 0.07 Bq/kg, 10.06 ± 0.06 Bq/kg, 39.94 ± 0.07 Bq/kg for 238U and 3.07 ± 0.07 Bq/kg, 1.85 ± 0.06 Bq/kg, 3.03 ± 0.09 Bq/kg for 232Th. Most of these obtained values are within the safety limits except for some values of 40K and 238U in maize stems which exceeded their safety limits. The mean of transfer factors of the radionuclides for the maize seeds and stems were 0.9858 and 1.5411 for 40K, 1.0841 and 3.4970 for 238U, 0.6768 and 1.1811 for 232Th radionuclides. The transfer factors are higher in maize stems than seeds and in some cases, exceeded unity which is the safety recommended limit. The mean annual ingestion dose due to the consumption of the maize seeds is 0.3824 mSv/yr for adults and 0.2375 mSv/yr for children. These results show that maize consumption does not pose a radiological health hazard to the consumers of maize from the study area.

In this work, the study of mass spectra of mesons with extended Cornell potential coupled with spin-spin interaction has been carried out. This involves approximating the Gaussian function to harmonic term in radial Schrodinger wave equation with the help of Greene-Aldrich approximation to centrifugal term using parametric Nikiforov-Uvarov (NU) method. The addition of spin-spin interaction to the extended Cornell potential helped in determining the singlet (s = 0) and triplet (s = 1) state of mesons which cannot be determined with the absence of the spin. Using the minimization approach implemented using the Mathematica package, the potential free parameters (a,b,c,σ and as) ere obtained by fitting the mesons mass spectra states with experimentally observed values of the Particle Data Group (PGD). The potential model was reduced to Pseudoharmonic, Kratzer and extended Cornell potential as special cases. The numerical energies of the Kratzer potential for selected diatomic molecules and for extended Cornell potential as applied to mass spectra of charmonium and bottomonium were in excellent agreement when compared to the work of existing literature. The total wave function for the proposed potential model was expressed in term of Jacobi polynomial. The wave function and probability density plots for charmonium were obtained using Mathematica package.
“I woke up and knew, spiritually, I have just accepted the faith”
Authors: Makhani-Belkin Tova
Published: September 2024

This paper focuses on how first-generation Bahá’ís view dreams and visions as confirming their choice to become Bahá’í. It presents life story interviews, highlighting the significance of their dream narratives in religious conversion. The study emphasizes that these dreams integrate their prior religious identity, mainly through the appearance of messengers of God serving as supernatural agents, which conforms to Bahá’í beliefs in progressive revelation. It advocates for anthropological attention to Bahá’í dream accounts, presenting dreams as premonitions or encouragements for conversion and acknowledging leaving a previous faith. The paper calls for investigating dreams’ bridging function, viewed by converts as a nonhuman and non-institutional force aiding conversion. It aims to explore agency in dreams concerning religious conversion by analyzing dream accounts from first-generation Bahá’ís’ life stories, illustrating how dreams influence and transform individual beliefs.

Organic UV filters are substances widely used as active ingredients in cosmetic products for protection against solar radiation. The frequent application of sunscreens containing multiple UV filters has led to their extensive release into the aquatic environment, posing adverse effects on aquatic organisms. There is a reason for concern about their presence in the environment due to their persistence and potential bioaccumulation in organisms, as well as their negative impact on the endocrine systems of humans and animals. Low concentrations of UV filters in natural waters make their detection challenging, thus requiring the selection of appropriate sample preparation techniques for analysis. This work aims to optimize solid-phase extraction for the analysis of selected UV filters in water. Organic UV filters commonly used as active ingredients in sunscreens were selected for analysis. High-performance liquid chromatography coupled with tandem mass spectrometry was used to identify and quantify the analytes. Five factors that are most significant for the efficiency of solid-phase extraction (sample volume and pH-value, salt concentration in the sample, eluent type and volume) were optimized. The optimized sample preparation technique enabled the examination of fiveselected UV filters with high extraction yields (75%–112%) and an enrichment factor of 150, allowing for trace-level analysis of these chemicals in water.

Published: September 2024

The development of an entirely machine parameter independent vector control algorithm for sensorless operation of the emerging brushless doubly fed reluctance generator (BDFRG) for wind power applications is put forward in this paper. A model reference adaptive system (MRAS) with on-line parameter identification has been implemented for the accurate rotor position and speed estimation enabling smooth, decoupled real and reactive power control of the grid-connected winding. The proposed control scheme is versatile and applicable to any BDFRG without the need for prior knowledge of its parameters or impractical off-line testing procedures often prone to errors. The excellent maximum power point tracking potential and disturbance rejection properties of the controller in the base speed region have been validated by realistic simulation studies using MW rated BDFRG wind turbine design data.
FEATURES OF LIMITING STATE DIAGRAMS FOR ACTIVE SYSTEMS UNDER MECHANO-SLIDING FATIGUE
Authors:   Belarusian State University, BOGDANOVICH Alexander V.
Published: September 2024

Experimental diagrams of limiting states of active systems under conditions of mechano-sliding fatigue are presented, as well as their analytical description. A graphical representation of the proposed equations for limit stresses (limits of mechano-sliding fatigue) is given based on the energy criterion of limiting states in the form of multicriteria diagrams of limiting states of various active systems (the ordinate axis on them serves as a strength scale, and the abscissa axis – as a tribological scale). Analysis of the proposed equations for limiting stresses, experimental diagrams of limiting states of different active systems showed that: 1) processes of friction and wear, depending on the conditions of their implementation, can significantly reduce, as well as significantly increase, the fatigue resistance of the active system; 2) cyclic stresses, depending on the test conditions, can both significantly reduce and increase the wear resistance of the active system.
Proselytism of the Catholic Clergy in the Western Russian Dioceses of the Russian Empire (on the Example of the Activities of Father Andrei Verzhbitsky)
Authors: Бабак К.С.
Published: September 2024

Западнорусский регион Российской империи практически во все времена своей истории являлся эпицентром конфессионального противостояния между православием и католицизмом. Это было вызвано политической конфронтацией между Московским и Польским государствами, усугубляемой еще и конфликтами на почве национальной принадлежности. Манифест «Об укреплении начал веротерпимости» от 17 апреля 1905 г. в западнорусском регионе Российской империи с новой силой спровоцировал рост конфессионального и национального противостояний. В статье предпринята попытка осветить прозелитическую деятельность католического духовенства на примере ксёндза Андрея Вержбицкого.

The Western Russian region of the Russian Empire has been, for most of its history, the epicenter of confessional confrontation between Orthodoxy and Catholicism. This was due to the political confrontation between the Moscow and Polish states, exacerbated by conflicts based on national identity. The Manifesto “On the Strengthening of the Principles of Religious Tolerance” of April 17, 1905, in the Western Russian region of the Russian Empire, provoked a resurgence of confessional and national confrontations. This article attempts to shed light on the proselytizing activities of the Catholic clergy using the example of Father Andrei Verzhbitsky.
Issues of reforming secondary spiritual education based on the materials of the Pre-Council presence of 1906
Authors: Пашков В.П.
Published: September 2024

В данной статье дан реферативно-аналитический обзор содержания протоколов заседаний V отдела Предсоборного присутствия 1906 г., посвященных реформированию системы среднего духовного образования в России. Внимание сосредоточено на духовных семинариях. Ключевые проблемы в системе среднего духовного образования, требовавшие внесения конструктивных изменений, к началу ХХ в. сводились к следующим: преобладание сословности, низкий уровень образованности будущих пастырей Церкви, девальвация духовных ценностей и представлений о благодати священного сана по причине частых случаев вступления на этот путь по принуждению. В ходе обсуждений на заседаниях Предсоборного присутствия были предложены меры по преодолению перечисленных и иных недостатков семинарского образования, которые могли стать конструктивными в случае их реализации. Прежде всего предлагалось впредь разделять общеобразовательный и профессиональный уровни, унифицируя содержание первого с целью предоставления возможности продолжения представителям духовенства обучаться в дальнейшем по программам светских учебных заведений. Результаты этих обсуждений актуальны и в настоящее время, так как духовные семинарии — самый многочисленный тип духовных учебных заведений РПЦ и процессы реформирования в них носят регулярный характер. Предреволюционный опыт в данном отношении может послужить аналоговой базой для принятия некоторых решений, а его анализ расширяет предметное поле церковно-исторической науки.

This research gives a summary and analytical review of the V department Pre-Council Presence of 1906 meetings protocols content, devoted to the reform of the secondary spiritual education system in Russia. Attention is focused on theological seminaries. By the beginning of the 20th century, the key problems in the system of secondary spiritual education, which required constructive changes, were reduced to the following: the predominance of caste, the low level of education of future Church pastors, the devaluation of spiritual values and the grace of holy orders due to frequent cases of entering this path under duress. During the discussions at the meetings of the Pre-Council Presence, measures were proposed to overcome these and other shortcomings of seminar education, which could become constructive if they were implemented. The main thing was that it was proposed to further separate the general education and professional levels, unifying the content of the first in order to allow the clergy to continue studying in the future according to the programs of secular educational institutions. The results are relevant at the present time, because theological seminaries are the most widely represented type of religious educational institutions of the Russian Orthodox Church and the reform processes in them are regular. The prerevolutionary experience in this regard can serve as an analog basis for making some decisions, and its analysis expands the subject field of church historical science.
Monastic “Turmoils” in “Stoglav” and the Message of Ivan IV to the Kirillo-Belozersky Monastery
Authors: Шапошник В.В.
Published: September 2024

На Стоглавом соборе 1551 г. рассматривались различные вопросы церковной жизни. Уже в первой главе «Стоглава», в которой кратко излагается программа Собора, указывается, среди прочего, что речь пойдет и о «монастырских чинех» — «исправлении» существующих недостатков, в том числе и в жизни монастырей, ярко описанных в некоторых «царских» вопросах. Для исправления ситуации в «Стоглаве» описываются правила монастырской жизни и устанавливаются меры по преодолению замеченных негативных явлений. Вместе с тем, даже спустя два десятилетия, с точки зрения Ивана Грозного, ситуация в ряде русских обителей не улучшилась, как это следует из текста его послания в Кирилло-Белозерский монастырь. Причем все «нестроения» связаны со знатью, с «боярами», которые стремятся разрушить строгие правила монастырской жизни.

At the Stoglav Council in 1551, various issues of church life were considered. And in the first chapter of “Stoglav”, which briefly outlines the program of the Council, it is indicated, among other things, that the focus will also be on “monastic rites” ― “correction” of existing drawbacks, in the life of monasteries as well, which are vividly described in some “tzarist” questions. To correct the situation, “Stoglav” defines the rules of monastic life and establishes the measures to overcome the observed negative phenomena. At the same time, just two decades later, according to Ivan the Terrible, the situation in a number of Russian monasteries did not improve, as it follows from the text of his message to the Kirillo-Belozersky Monastery. Moreover, all the “turmoils” are associated with nobility, with “boyars” who seek to destroy the strict rules of monastic life.

Authors:   , Dornelas Lorraine Rossi Signorelli Machado
Published: September 2024

A doença renal crônica (DRC) é uma doença comum, progressiva e irreversível em cães. A inflamação e a proteinúria estão relacionadas ao processo de progressão da DRC. A realização de estudos na busca por marcadores precoces e indicadores de grau e local de inflamação renal, a fim de auxiliar no diagnóstico e prognóstico é de extrema relevância. Foram utilizadas 22 amostras de caninos com raça, idade e sexo aleatórios, portadores de DRC em diferentes estadiamentos e 5 animais hígidos, para avaliar o perfil de proteínas da urina por nano LC- MS/MS. Os animais foram divididos em cinco grupos experimentais: grupo C (GC) composto por animais hígidos (controle); grupo 1 (G1) composto por animais com DRC estágio I; grupo 2 (G2), composto por animais com DRC estágio II; grupo 3 (G3), composto por animais com DRC estágio III; e grupo 4 (G4), composto por animais com DRC estágio IV. Os objetivos deste estudo foram compreender a caracterização do perfil de proteínas urinárias em cães considerando o grau de acometimento renal, por meio da realização de uma revisão sistemática sobre o assunto e da identificação de proteínas urinárias por espectrometria de massas (nano LC-MS/MS) em animais saudáveis e com DRC nos estágios de I a IV, sugerindo, se pertinente, marcadores que possam auxiliar no diagnóstico precoce e prognóstico da DRC. Como resultado da revisão, observou-se proteínas com potencial para biomarcador, uma diversidade metodológica nos estudos descritos empregando proteômica urinária, além de importantes pontos de viés. Além disso, o experimento identificou 65 proteínas por meio da metodologia empregada, notando-se uma tendência ao aumento das proteínas de acordo com a gravidade da DRC, tendo destaque para haptoglobina e transferrina como possíveis biomarcadores e para o papel do sistema complemento na patogenia da doença, necessitando-se de futuros estudos para maior elucidação.

Aceites esenciales: Una estrategia ecológica para el control de Aphis craccivora en un cultivo agrícola
Authors: Escobar Quispe Bryan Rey Fabricio , Ramirez Huanca Gladis Mariela , Lazo Ramos Richard Sabino
Published: September 2024

El pulgón negro (Aphis craccivora) afecta gravemente los cultivos de Medicago sativa, reduciendo tanto su rendimiento como su calidad, y causando pérdidas económicas significativas para los agricultores. Aunque el control tradicional con pesticidas sintéticos es efectivo, conlleva problemas como la contaminación, la resistencia del insecto y riesgos para la salud. En este contexto, los aceites esenciales (AE) emergen como una alternativa prometedora para un manejo sostenible de esta plaga. El objetivo del estudio fue evaluar el efecto insecticida de aceites esenciales extraídos mediante destilación por arrastre de vapor de cuatro plantas aromáticas (Schinus molle, Eucalyptus globulus, Origanum vulgare, Equisetum arvense) como una opción ecológica frente a los pesticidas sintéticos. Se empleó un diseño experimental de bloques completamente al azar, aplicando diferentes dosis de AE (1, 3 y 5 µl) y tiempos de exposición (10, 20, 40 y 60 minutos) en placas Petri con Aphis craccivora. Los resultados indicaron que los AE de eucalipto y orégano fueron los más efectivos, logrando una mortalidad significativa (8 ± 0,00) a los 60 minutos, siendo la dosis adecuada de 3 µl. En contraste, el AE de molle mostró una eficacia moderada, y el de cola de caballo fue el menos efectivo, con baja mortalidad en todas las dosis y tiempos. El ANOVA reveló diferencias significativas en la efectividad entre los tratamientos (p < 0,05), y el análisis de regresión múltiple mostró una fuerte correlación entre la dosis y el tiempo de exposición con la mortalidad observada.

Eficacia del extracto estandarizado de Ginkgo biloba como tratamiento preventivo del deterioro cognitivo
Authors: González Fernández Inmaculada
Published: September 2024

El extracto estandarizado de Ginkgo biloba, EGb 761®, es un principio activo cuya actividad antioxidante a nivel mitocondrial se manifiesta por la captura de radicales libres. Los glucósidos flavónicos de G. biloba protegen a las membranas celulares de la peroxidación lipídica, lo que contribuye a mejorar el metabolismo energético neuronal, ejerciendo un efecto neuroprotector debido a su composición en ginkgólidos y bilobálidos. Son destacables los efectos hemodinámicos y hemorreológicos de los ginkgólidos A, B, C y J. Además, la optimización de la función neuronal que realiza el EGb 761® está directamente relacionada con el control del exceso de cortisol, al que se le ha atribuido ser causa principal del deterioro cognitivo y de la pérdida de memoria. El exceso de cortisol propicia un déficit de glucosa cerebral lo que, unido a la disminución de neurotransmisores y neuropéptidos, causa degeneración neuronal y desregulación endocrina, lo que induce menores niveles energéticos, con disminución del impulso sexual y debilitamiento del sistema inmunitario.

Sentiment Analysis (SA) is an exciting research area in Urdu text classification tasks. Due to its complicated morphology, sentiment analysis in Urdu poses various challenges. The lexicon-based technique is the preferred approach for Urdu sentiment analysis for its high accuracy rate. This approach requires a comprehensive manual list of positive and negative words. Sentiment classification can be effectively achieved using morphology-driven methods. For this purpose, an effective Urdu sentiment analyser employing morphological rules for performing Urdu sentiment analysis is proposed. The application of the rules depends on the input words' lexical category and prefixes. Sentiment classification rules are proposed based on the prefixes attached to negative sentiment carrier words.  A thorough evaluation with reasonable Urdu text document/dataset size is performed. The empirical assessment proved that the proposed rule-based method achieved satisfactory precision, recall, and accuracy.
