Published: October 2024

Introduction: Diabetes mellitus (DM) and thyroid dysfunction (TD) are two of the most prevalent endocrine disorders globally. Both conditions have significant effects on metabolism and are known to influence each other. Thyroid hormones play a crucial role in glucose homeostasis by affecting insulin secretion, sensitivity, and glucose metabolism.Conversely, altered glucose metabolism in diabetes can impact thyroid function, leading to a higher prevalence of thyroid disorders in diabetic patients. Understanding this relationship is important for improving the clinical management of patients with Type II DM. However, there is limited data on the prevalence of thyroid dysfunction in diabetic populations within specific regions. Methods: A cross-sectional descriptive study was conducted from February to September 2023 among 209 patients diagnosed with Type II DM at a tertiary care center after obtaining ethical approval from Institutional Review Committee(Reference No: 367 (6-11) E2). Thyroid function was assessed using thyroid-stimulating hormone (TSH), free T3 (FT3), and free T4 (FT4) levels. Thyroid dysfunction was classified into hypothyroidism and hyperthyroidism based on standard clinical and laboratory criteria. Data management involved entry into Microsoft Excel, verification for accuracy, and subsequent analysis using SPSS version 29.Results: The study included 209 patients (61% female, 39% male), with a mean age of 65.87 ± 13.7 years. The prevalence of thyroid disorders was 77(36.8%): 53(25.3%) hypothyroidism,24 (11.4%) hyperthyroidism among patient with type II diabetes mellitus.Conclusions: Our study shows a high prevalence of thyroid disorders, especially subclinical hypothyroidism, in individuals with type 2 diabetes. Poorly controlled blood glucose (HbA1c ≥ 7.5) significantly increases the risk, underscoring the need for routine thyroid screening in T2DM management
The Position of Selected English Dominicans Towards the Immaculate Conception in the Pre-tridentine Era
Authors: Beyga Paweł
Published: October 2024

The Immaculate Conception of the Mother of Christ is a truth of the Catholic faith that was only dogmatised by Pius IX in 1854. Until then, there had been debate among theologians regarding this Marian privilege. By means of selected examples the article shows the attitude of English Dominicans to the Immaculate Conception of Mary between the 13th and 16th centuries. It transpires that the members of the Order of Preachers in the British Isles presented an extremely diverse positions. One can find both strongly dissenting positions and those manifestly in favour of the Immaculate Conception. It is extremely interesting to note that in their arguments for the Immaculate Conception, some Dominicans distanced themselves from the continental theology represented by Aquinas. The way the Dominicans conceptualised the Immaculate Conception was closer to that represented by the twelfth-century theologian and historian Eadmer.
Pobożność maryjna w ujęciu Josepha Ratzingera/ Benedykta XVI
Authors: Borto Paweł
Published: October 2024

Artykuł przedstawia rozumienie pobożności maryjnej i jej teologiczne uzasadnienie w ujęciu Josepha Ratzingera/Benedykta XVI. Podstawą dla prowadzonych analiz były przede wszystkim teksty mariologiczne o charakterze systematycznym, jak i wybrane wypowiedzi Benedykta XVI. Przeprowadzona analiza wykazała, że zagadnienie pobożności maryjnej J. Ratzinger ściśle łączył z refleksją mariologiczną. Tę zaś zawsze rozwijał w ścisłym związku z tajemnicą Objawienia oraz z zachowaniem właściwej równowagi między mariologią chrystotypiczną a eklezjotypiczną . Jednocześnie w poglądach Ratzingera na rolę pobożności maryjnej zaszła pewna zmiana. Początkowy dystans wobec pewnych form pobożności maryjnej ustąpił postawie docenienia tej pobożności. Wnioski z przeprowadzonej analizy pozwalają stwierdzić, że proponowany przez Ratzingera model pobożności maryjnej ściśle wiąże się z logiką Objawienia i autentyczną czcią oddawaną Bogu, wypływa z lektury Pisma Świętego, pozostaje wierny treściom dogmatów maryjnych oraz wskazuje na Maryję jako doskonałą uczennicę Pana i uosobienie Kościoła. O ile wnioski te zostały wskazane już w innych publikacjach, to należy podkreślić, że w poglądach bawarskiego teologa trzeba uwzględnić pewną ewolucję. Poglądy te bowiem cechuje wprawdzie pewien constans, ale z czasem w twórczości Ratzingera dochodzi do głosu większa uwaga poświęcona praktykowaniu pobożności maryjnej. Jest ona postrzegana nie tylko jako wyraz posłuszeństwa słowom Pisma (por. Łk 1,48), ale w przeżywanie tajemnicy Boga i Kościoła wnosi wymiar osobowy, pozwala docenić lokalne tradycje i związaną z nimi cześć okazywaną Maryi oraz uczy, że spotkanie z Bogiem domaga się również zaangażowania serca, które także poznaje.
Dziewictwo Maryi w zrodzeniu Chrystusa na podstawie kazań św. Augustyna na Boże Narodzenie
Authors: Jaśkiewicz Sylwester
Published: October 2024

Dziewictwo Maryi w zrodzeniu Chrystusa jest we współczesnej kulturze i mentalności czymś zgoła archaicznym, a nawet śmiesznym. Stawienie czoła takiej sytuacji wydaje się być możliwe jedynie dzięki dostarczeniu wierzącym bardziej przekonujących wyjaśnień i uzasadnień o charakterze merytorycznym i źródłowym. Odniesienie się w takiej sytuacji do autorytetu św. Augustyna i jego kazań na Boże Narodzenie (In Natali Domini), nie jest przypadkowe. Artykuł stara się w pierwszej kolejności ukazać poród Dziewicy (Virginis partus) i jego przesłanie płynące z bożonarodzeniowego nauczania biskupa Hippony, które stanowi zarazem zręby jego mariologii. Augustyn kwestię dziewictwa Maryi w czasie porodu (in partu) widzi jako konstytutywny element Jej trwałego dziewictwa i tak też winno ono być odczytywane również dzisiaj.
Biblijne świadectwa o godności Maryi w "lex orandi" Kościoła
Authors: Szymik Stefan , Pałęcki Waldemar
Published: October 2024

Maryja jest ikoną chrześcijańskiej wiary i obiektem szczególnej czci. Jest tak, chociaż brak wyraźnych śladów kultu maryjnego w tekstach biblijnych. Niemniej późniejszy rozwój pobożności maryjnej ma swoje źródła właśnie w Biblii, czego dowodzą teksty liturgiczne. Ten teologiczny fenomen recepcji maryjnych tekstów biblijnych w lex orandi Kościoła stanowi przedmiot przedłożonych analiz. O kolejności i strukturze analiz zdecydowały wypowiedzi trzech postaci biblijnych: anioła Gabriela (Łk 1,26–38), krewnej Elżbiety (Łk 1,39–45) i anonimowej kobiety z tłumu (Łk 11,27–28). Na drodze badań interdyscyplinarnych, na bazie metody historyczno-krytycznej uzupełnionej o analizy narracyjne i kontekstualno-opisowe, artykuł naświetla oddziaływanie orędzia biblijnego (Wirkungsgeschichte) na liturgię Kościoła na przykładzie godnościowych tytułów Maryi w lex orandi Kościoła na przestrzeni wieków. Okazuje się, iż słowa postaci biblijnych były istotną podstawą rozwoju pobożności maryjnej. W świetle Biblii Maryja jest szczęśliwą (μακαρία), błogosławioną (εὐλογημένη) i pełną łaski (κεχαριτωμένη) Matką Pana (Łk 1,43). Celebracja tej prawdy w akcie liturgicznym owocowała w ciągu wieków jeszcze pełniejszym poznaniem wielkiej godności Maryi.

Extreme weather events are often described by meteorologists as the ‘fingerprint of climate change’. These climate-induced natural disasters are becoming more damaging and more frequent, at times occurring close to elections and impacting upon them. As climate-related natural hazards will continue to do so, states must consider protecting elections and building resilience. This case study analyses preparedness, actions and results on the part of election officials and their election emergency policies in New Jersey and (as a secondary focus) New York, neighbouring states on the East Coast of the United States, as they faced an incoming hurricane within one week of a national election in 2012.

The purpose — to conduct a comparative analysis of the course of post-COVID syndrome in patients with rheumatoid arthritis and spondyloarthritis. Material and methods. The study included 140 patients: 91 patients (65%) with rheumatoid arthritis (RA) and 49 (35%) with spondyloarthritis (SpА). The presence of post-COVID syndrome, RA and SpA activity were assessed and risk factors for exacerbations of major diseases were identified 3, 6, 9, 12 months after COVID-19. Results. The incidence of post-COVID syndrome among patients with RA was 73.7%, among patients with SрA — 61.3%. Most often, patients with RA and SpA reported fatigue, and/or muscle pain, and/or headaches, and/or dysautonomia, and/or cognitive impairment 87.3% and 71%, respectively, increased joint pain — the second most common complaint — 81.6% and 65.1%, respectively. Patients with RA had more frequent and longer complaints characteristic of post-COVID syndrome compared to patients with SpA. The maximum value of activity in RA, AS, and PsA was revealed 3 months after COVID-19. Among patients with RA, the main factors influencing the frequency of exacerbations after 3 months were cardiovascular diseases, female gender, viral lung damage, RA activity before NCI, COVID-19 symptoms; among patients with PsA: exacerbation of PsA before COVID-19, initial glucocorticosteroid therapy, COVID-19 symptoms; among patients with AS: symptoms of COVID-19. Conclusions. Among patients with RA, regardless of the severity of COVID-19, post-COVID syndrome was more common compared with patients with SpA. The largest number of patients in exacerbation was recorded 3 months after the COVID-19. The largest number of risk factors for exacerbations at 3 months after COVID-19 was recorded among patients with RA and PsA; among patients with AS, only the symptoms of COVID-19 were affected.

The purpose — to study the characteristics of polysynaptic reflex excitability of the brain stem based on an electroneuromyographic research of the blink reflex in patients with exogenous constitutional obesity (ECO). Material and methods. 288 women (mean age 37.5 (2.8) years) with ECO and 45 healthy women of the same age group were examined. All patients underwent a clinical and anthropometric examination, including quantitative indicators of body size and weight and electroneuromyographic study of the blink reflex (BR). Results. The anthropometric study revealed the presence of two variants of fat deposition topography — android (AT) and gynoid (GT) types. The ratio of ECO-AT and ECO-GT in this sample was 41.28% and 58.72%, respectively. Patients with ECO-GT showed a significant increase in the duration of the R2 component of the BR (44.1 (1.5) ms) (p <0.01), a reduction in its latency (35.5 (0.8) ms) (p < 0.05) and a decrease in the threshold (1.9 (0.1) mA) (p < 0.01) compared to the indicators of healthy subjects. A direct significant correlation was found between the level of polysynaptic reflex excitability and the level of obesity (r = 0.75, p < 0.05). The data obtained characterize the role of a lack of inhibition processes in the central nervous system and a functional deficit of the sensorimotor component in the ECO development mechanisms, with a disorder of autonomic nervous system and behavioural and emotional disorders, including eating behavior. As the degree of obesity increases, as well as with a more unfavorable pathogenetic type of ECO, the severity of changes in polysynaptic reflex excitability of the brain stem also increases. Conclusions. The study of polysynaptic reflex excitability of the brain stem by electroneuromyographic BR testing shows the role of dysfunction of the CNS suprasegmental parts in the ECO development and progression.

As is known, sport is accompanied by a critical level of physical load, which leads to a steady increase in injuries among athletes. However, sex differences in the risk of tendon and ligament injuries have been reported, with the relative risk of anterior cruciate ligament (ACL) rupture being 2 to 6 times higher in young female athletes compared to male athletes. This indicates that sex differences in the biomechanical properties of tendons are significant during the period of life when the sex hormonal profile is noticeably different in women and men. The purpose — to determine the influence of menstrual cycle phases on the frequency and nature of injuries in professional female football players. Material and methods. 31 athletes of the top division women’s youth team were examined, average age 19.6 ± 1.8. The menstrual cycle was divided into 3 phases: follicular phase (phase 1), ovulation (phase 2), luteal phase (phase 3). Injuries during the annual macrocycle were analyzed. All injuries were classified into muscle ones, injuries of the capsular-ligamentous apparatus, and bone injuries. Injury rates and ratios were calculated for the total number for each injury type. Statistical processing of the data was carried out using the statistical software package SPSS (v.18.0). The χ2 test and Fisher’s exact test were used to analyze the data. Differences were considered statistically significant at p < 0.05. Results. Analysis was carried out for 267 cycles and 39 injuries in 31 players during one playing season. 43.6% of the total injuries occurred in the luteal phase, 46.2% in the follicular phase, and 2.6% in the ovulation phase. In the follicular phase of the menstrual cycle, muscle injuries were more often recorded in female athletes — 75.0% of cases, while damage to the capsular-ligamentous apparatus in this phase was detected only in 33.3% (p = 0.003), and bone injuries were recorded in 50.0% (p = 0.037). Thus, muscle injuries in the follicular phase of the menstrual cycle were statistically significantly more common. The incidence rates of capsular-ligamentous injuries (33.3%) and bone injuries (50.0%) were not statistically significantly different (p = 0.147). Conclusion. The most common injuries among young female football players were injuries to the capsular-ligamentous apparatus (48.7%), followed by muscle injuries (30.8%), while injuries to the capsular-ligamentous apparatus were most characteristic of the luteal phase, and muscle injuries predominated in the follicular phase of the menstrual cycle.

The purpose — to evaluate the relationship between quality of life parameters and damage to joints and entheses in patients with inflammatory bowel diseases (IBD). Materials and methods. The study included 95 patients with IBD (ulcerative colitis (UC) and Crohn’s disease (CD)). The quality of life of patients was assessed using the SF-36 questionnaire. Each patient underwent clinical and ultrasound examination of the joints and entheses of the upper and lower extremities. A comparative analysis of the frequency of joint damage and enthesis in patients with UC and CD was carried out. We also assessed the relationship between the number of affected joints and entheses and the quality of life of patients with IBD. Results. The general parameter of physical well-being was 43.53 (35.67; 51.66), the general parameter of mental well-being was 38.53 (31.13; 48.37). 61 patients with IBD (64%) noted pain in the joints at the time of examination and/or in history. During clinical examination, arthritis was detected in 18 (19%) patients, pain on palpation of entheses was noted in 49 patients (52%). According to ultrasound, synovitis was detected in 41 patients (43%), enthesites were detected in 72 patients (76%). There were no significant differences in the frequency of joint damage and enthesis between patients with different nosologies. An inverse correlation was observed between the number of synovitis with vascularization and scales of physical functioning (SR = -0.26; p = 0.01), vital activity (SR = -0.29; p = 0.005), as well as with the general parameter of physical well-being (SR = -0.23; p = 0.024). The number of enthesitis was inversely correlated with the pain intensity scale (SR = -0.22; p = 0.036). Conclusion. Joint and enthesis damage in IBD is a common problem associated with the quality of life of patients. Its study is necessary for the timely diagnosis of these lesions and the selection of therapy. Particular attention should be paid to the issue of enthesopathy in IBD, information about which is scarce.

With the increasing use of wood resources, wood waste disposal is becoming a more pressing issue. Wood waste can be effectively processed and reused, thus reducing environmental impact. Our study proposes using wood waste to produce sodium carboxymethyl cellulose (Na-CMC) with enhanced physical and chemical properties. The paper explores a promising approach to processing Scots pine (Pinus sylvestris L.) wood waste via the suspension method to obtain the biopolymer Na-CMC. The ability to convert pine sawdust into Na-CMC meets the demand for high-quality wood raw materials, expands the biopolymer's applications, and reduces the environmental and economic burden of wood consumption. The aim of this study is to produce Na-CMC from Scots pine sawdust at 60°C and 80°C and investigate the biopolymer’s physical and chemical properties. In laboratory experiments, Na-CMC samples were synthesized at 60°C and 80°C using sodium hydroxide, propanol-2, and sodium monochloroacetate (Na-MCA). The physical and chemical properties of Na-CMC were studied such as functional groups (hydroxyl, methylene, carbonyl), alcohol and ether bonds by IR spectrophotometry; molecular mass, polymerization degree, and viscosity of polymer solutions by viscometry; carboxymethyl groups by conductometric titration; and product yield and solubility by gravimetry. The scientific and practical significance of the chemical modification of wood sawdust cellulose has been established, with carboxymethylation proving effective at 60°C
Smelling-based hunting optimization for battery–Super/Ultracapacitor hybrid energy storage station in wind/solar generation system using Siamese neural network
Authors: Tiwari Pradeep Kumar , Srivastava Manish Kumar
Published: October 2024

To ensure the continuous supply of power in remote areas utilizing renewable energy resources is significant. Hence, in this research, an effective energy management method for a small-scale hybrid wind-solar-battery-Ultra-capacitor-based microgrid is proposed. Hybrid Energy Storage System (HESS) has been presented in conjunction with wind and solar energy conversion technologies characterized by coupling of power electronic converters, neural networks, optimization, battery, controllers, and ultra-capacitor storage systems to attain the intended performance. The power balance is regulated via an energy management system by considering the fluctuation in load demand and renewable energy power generation. Further, the voltage controller utilizes the deep Siamese neural network (deep SNN) that effectively carries out energy management among the hybrid renewable energy sources. The smelling-based hunting optimization assists in optimal parameter tuning and training of the deep SNN for enhancing the HESS’s efficiency. In addition, the microgrid operates independently and offers a testing area for different energy management systems and testing scenarios. The proposed small-scale microgrid, which is based on renewable energy, can serve as a significant testing area for methods utilized in smart grid applications. The proposed SBHO model’s efficiency is determined by varying the voltage, current, and power of the wind, solar, battery, and ultra-capacitor measurements. The current capacity of the battery reaches −11.06A and the battery voltage reaches 259.831 V in 0.82 s. The DC load measurement utilizing the SBHO approach obtained a DC bus voltage of 357.11V, a load current of 3.348 A within 0.82 s, and in DC power load attained the 1195.58 W within 0.82 s. The battery’s SOC by applying the smelling-based hunting optimization is gradually increased to 50.008% in 0.82s.In terms of the PV measurement, the PV current, PV voltage, and PV power are obtained as 4.238A,241.08V, and 1021.64W for the SBHO approach which surpasses other competent techniques. The ultra-capacitor current ranges from 35A to 40A with reduced heavy discharge of SOC from 98% obtained on evaluating the performance. The output power of wind using a boost converter remains 3000 W with few harmonics.
Automated recognition of mental cognitive workload through nonlinear EEG analysis
Authors: Zheng Zhihong , Weng Lin
Published: October 2024

Nowadays, with the remarkable advancements in detection instruments and artificial intelligence, there has been extensive utilization of human mental state monitoring in various domains. Few studies have explored how nonlinear analysis methods can detect cognitive workload despite the complex nature of EEG signals and advancements in signal processing techniques. In addition, the fuzziness of human mental conditions makes the need to use fuzzy engineering tools tangible in this field. Therefore, this investigation aimed to develop a decision support algorithm to improve previous efforts for the classification of task EEG and resting through machine learning algorithms. Various nonlinear features were calculated from all 19 EEG channels: Hurst exponent, Lempel–Ziv complexity, detrended fluctuation analysis, Higuchi fractal dimension, Katz fractal dimension, permutation entropy, singular value decomposition entropy, Petrosian fractal dimension, sample entropy, and Lyapunov exponent. During the classification step, a newly developed EPC-FC (Expert per Class Fuzzy Classifier) is introduced, utilizing an ensemble framework with specialized sub-classifiers for identifying a particular condition. By training sub-classifiers with the negative correlation learning (NCL) approach, the EPC-FC is designed to be exceptionally adaptable. Additionally, the separation of sub-classifiers within each class provides versatility and clarity to the system’s design. The proposed approach based on fuzzy systems and nonlinear analyses was applied to EEG data for mental workload recognition, which provides an excellent accuracy of 98.50% and an F1-score of 98.56% which is much higher than previous findings in this field. Also, the obtained results indicate that utilizing the proposed EPC-FC classifier maintains a consistently high accuracy exceeding 90% across various levels of SNRs. The obtained results proved the high potential of nonlinear analysis to detect cognitive states of the brain, which is consistent with the nonlinear and fuzzy nature of EEG data. Other nonlinear approaches should be considered for future studies to improve the current results.

Authors: Manaf Sofwan , Kurniawan Muhammad Irfanudin
Published: October 2024

A strong philosophical foundation in the management of santri alumni management is expected to maintain the values that have been instilled during the education process in Pesantren when they are already in the community. However, modernity and reality in urban areas become a challenge for alumni in maintaining the religious character formed on traditional values in pesantren. The purpose of this article is to examine the implementation of the Panca Dharma and Panca Jiwa paradigms in the management of alumni and pesantren networks in urban areas. This research is a descriptive-analytical qualitative research using a case study approach. Primary data is in the form of observations and interviews with figures in the alumni management process at Pesantren Darunnajah and Pesantren Darussalam Gontor. While secondary data is in the form of written sources and scientific references including books, journal articles, theses, and theses related to the research topic. Data were collected using observation and interview methods and analysed using the content analysis method. The results showed that the principles of Panca Dharma and Panca Jiwa are formed on the emotional relationship between santri and kyai, which results in obedience and compliance. This is an effort of pesantren in maintaining religious santri in urban areas to remain in the frame of religious attitude inclusivism. Alumni's pride and appreciation for the pesantren can be seen from their awareness of worship and achievement in the community. Through a strong philosophical foundation, pesantren have succeeded in giving birth to thousands of alumni with various professions such as politicians, judges, businessmen, clerics and religious leaders with their pesantren, officials of state agencies, private sector, military and others. The orientation of pesantren education that prioritises society makes them more flexible in moving amid the dynamics of urban reality.
Early Renaissance Concepts of Time and the Invention of Mechanical Clocks
Authors: Nosonovsky Michael
Published: October 2024

Mechanical clocks appeared in Europe at the end of the thirteenth century and became widespread during the fourteenth century. Clocks utilized a periodic process – the oscillation of a verge – for accurate time measurement, which is consistent with the Aristotelian concept of time defined by motion. The concept was at the center of debates among scholastics and theologians, which culminated in the Church's Condemnation of Aristotelian teaching in 1277. The debate also led to the discovery of Impetus (inertial motion) by Buridan and Oresme. Sand clocks became a popular device at about the same time. The pendulum clocks invented by Huygens in the 1650s utilized linear oscillations, which, unlike the earlier verge mechanism, had their natural frequency. Both mechanisms are analyzed to explain why the introduction of the linear oscillator led to a 30-times accuracy improvement of the clock.

Published: October 2024

This paper explores the Vedic foundations of secular mindfulness, particularly examining the influences of Advaita Vedānta, Patañjali Yoga, and Haṭha Yoga systems on the development of contemporary mindfulness practices, specifically as popularized by Jon Kabat-Zinn through his Mindfulness-Based Stress Reduction (MBSR) program. While mindfulness is often recognized for its Buddhist origins, this research highlights the underexplored connections to Vedic contemplative traditions, demonstrating that secular mindfulness may owe a significant debt to these ancient systems. The study delves into key Vedic concepts such as intrinsic wholeness, perpetual availability, and non-duality, and compares them with the philosophical underpinnings of Kabat-Zinn's mindfulness approach. Through an analysis of primary Vedic texts and Kabat-Zinn's own writings, the paper argues that his secularization of mindfulness is not only an innovative adaptation but also deeply influenced by Vedic philosophy, particularly Advaita Vedānta. The findings suggest that secular mindfulness, as practiced today, may be more closely aligned with Vedic traditions than previously acknowledged, offering a new perspective on the historical and philosophical roots of this widely adopted practice.
The Control of Exports – A Significant Factor of the Non-proliferation of Weapons of Mass Destruction

Extensive changes have occurred during the past few years in the sphere of international security. The most prominent of these is the lesser likelihood of nuclear war between the super-powers and of a worldwide armed conflict, endangering human civilisation. But at the same time, the problem of the proliferation of weapons of mass destruction and the possibility of their utilization in local conflicts, representing a new threat to world peace and security, is coming to the forefront.
The proliferation of nuclear, chemical and biological weapons and their carriers is regarded as a threat in the 21st century and requires the utmost and widest attention of world organisations and the pubic. Arms control, the control of exports and anti-proliferation measures are the major factors of the system of the struggle against proliferation. The authors of this essay deal in great detail with the control of exports as one of the key elements of a comprehensive non-proliferation strategy. They analyze the system of export control and its fundamental elements, international treaties banning the proliferation of weapons of mass destruction as well as control regimes of multilateral export controls. The Czech Republic takes an active part in this process since it participates in the activities of international control associations, involved in the sphere of the non-proliferation of conventional arms and weapons of mass destruction.
The further improvement of export control from the point of view of current non-proliferation which is characterized mainly by global integration and rapid technological progress, lies in increasing the effectiveness of national export control systems and in international cooperation in creating a global export central system.

Authors: Salazar Luna Patricio , Anderson Vásquez Hazel
Published: October 2024

Introducción: El incumplimiento de la dieta y la ingesta de líquidos del paciente en hemodiálisis pueden provocar la acumulación de metabolitos tóxicos en la sangre, lo que provoca una mayor morbilidad y muerte prematura. Objetivo: determinar los parámetros bioquímicos y la adherencia a la dieta en los pacientes con diabetes tipo 2 en hemodiálisis que asisten a la unidad de diálisis del Hospital General IESS Riobamba. Métodos: se realizó una investigación de enfoque cuantitativo, prospectiva, cuasi-experimental de diseño longitudinal en 87 sujetos con nefropatía diabética de ambos sexos con edades entre 40 y 70 años, que estuviesen recibiendo tratamiento de diálisis. Se realizaron mediciones bioquímicas (hematológicas, perfil metabólico y lipídico, albúmina y electrolitos) y se aplicó el cuestionario de no adherencia a dieta y líquidos para hemodiálisis (DDFQ) Resultados: Se encontraron diferencias significativas (p<0,05) en el género masculino en los siguientes parámetros: hemoglobina, creatinina y albumina. Mientras que en las mujeres se encontraron diferencias significativas en la concentración de ácido úrico. En ambos sexos se observaron diferencias significativas en las concentraciones de fosforo y potasio (p<0.05). Alrededor de 80% de los pacientes manifestó un grado de desviación de 1 a 3 (entre la no desviación y la desviación moderada) a las restricciones de dieta y líquidos Conclusión: se encontró en la mayoría de los pacientes una buena adherencia a las restricciones de dieta y líquidos que guardó relación con los principales parámetros bioquímicos estudiados.
An one-dimensional inverse problem for the wave equation
Authors:   Sobolev Institute of Mathematics, Romanov V , Bugueva T
Published: October 2024

For the wave equation with inhomogeneity σ(x)um t + q(x)up a forward and an one-dimensional inverse problems are studied. Here m > 1 and p > 1 are real numbers. The forward problem is considered in the domain x > 0,t > 0 with zero initial data and Dirichlet boundary condition at x = 0. An unique solvability theorem of this problem is proved. The inverse problem is devoted to determining the coefficients σ(x) and q(x). As an additional information for recovering this coefficients, two forward problems with different Dirichlet data are considered and traces of the derivative of their solutions with respect to x are given at x =0 on a finite interval. For the inverse problem a local existence and uniqueness theorem is established.

For the regions with a long-term snow cover, the amount of solid precipitation is one of the driving factors in the formation of floods. The article considers the possibility of using the orographic correction to the velocity of vertical movements of air masses due to the relief in estimating winter precipitation and forecasting maximum snowmelt-induced stages. The significant influence of autumn freezing on the floodplain inundation and, accordingly, maximum water levels of the Ob River near the city of Barnaul is shown.

In this article, for the direct problem, which consists of finding the velocity potential and the displacement of boundary points in the wave equation of memory type with initial and boundary acoustic conditions, the inverse problem of determining the memory kernel by the integral overdetermination condition is studied. By introducing a new function, the problem is reduced to a problem with homogeneous boundary conditions. Using the technique of estimating integral equations and the contraction mappings principle in Sobolev spaces, the existence and uniqueness theorem for the inverse problem is proved.

This paper aims to identify exchange coefficients of a nonlinear polynomial tri-compartmental catenary system of (α + β) order. This is based on two principal procedures. The first procedure presented is related to the recommended solution consisting of introducing an adequate time t∗ > 0 in a way to be defined. That is to say: wait a moment to allow the exchange to settle in the polynomial (α +β) order nonlinear catenary system after injecting the quantity into the main compartment, then measure this compartment with compartment 2, at this time t∗ > 0. In the second procedure, we apply the Taylor formula to linearize the nonlinear system and identify the exchange coefficients. In the end, we will prove that the linearization method is stable

Published: October 2024

A numerical study of the processes of heat and mass transfer in the furnace of a thermogravimetric analyzer was carried out, aimed at improving the accuracy of determining the kinetic characteristics of samples during their thermal transformations in different media. Validation of the model and prognostic estimates were carried out in relation to specially conducted thermogravimetric studies of the conversion of fossil and renewable carbon-containing raw materials in successive processes of decarbonization (combustion) and carbonation (mineralization of ash residue). The application of the study results allows to calculate the actual concentrations of the reagent over the sample uncontrolled by the device during pulsed switching of media and the actual temperatures of the sample during its thermochemical transformations.
Modeling the transmission dynamics of banana bunch top disease in banana plants
Authors:   Sokoine University of Agriculture, Department of Mathematics and Statistics, Mrope F , Jeeva N
Published: October 2024

Banana Bunch Top Disease (BBTD) is a severe viral infection that poses a significant threat to banana production in tropical regions. Caused by the Banana Bunchy Top Virus (BBTV) and transmitted primarily by the banana aphid (Pentalonia nigronervosa), BBTD results in stunted growth and poor fruit production, leading to substantial economic losses. This paper presents a mathematical model to analyze the transmission dynamics of BBTD in banana plants and evaluate various control strategies using the Next Generation Matrix approach to compute the basic reproduction number R0. The study reveals that effective control of aphid populations, timely removal of infected plants, and the use of virus-free planting material significantly reduce the spread of BBTV and improve plant health. Increasing the removal rate γ and managing the transmission rate β are crucial strategies for controlling the disease, while elevated aphid infection rates λ and progression rates σ exacerbate its spread. Numerical simulations highlight the effectiveness of targeted interventions, including the application of pesticides and the introduction of resistant banana varieties. The study recommends that, in addition to current control measures, more focus should be placed on comprehensive monitoring programs, early detection of symptoms, and community education on BBTD management strategies. Enhanced efforts in these areas are crucial to reducing the incidence of BBTD and improving the resilience of banana crops.

The present work deals with the experimental and numerical study of steadystate conjugate heat transfer during impingement of turbulent air jet over a heated stainless steel. The plate is heated using copper heater located at the middle. The temperature field is measured using an infrared camera and compared with the numerical simulations. Numerical simulations are performed using three-dimensional finite volume based formulation. The turbulence shear-stress transport (SST) is modeled using k−ω model based on the Reynolds averaged Navier Stokes (RANS) equations. The numerical simulations are in good agreement with the experimental data with marginal discrepancy in the steel plate region due to the contact thermal resistance between steel and copper. It is observed that the local Nusselt number increased in the stagnation region with increasing velocity of the impinging turbulent flow and practically unaltered in the region of the steel plate.
