Authors: ЧИГИРИНЕЦЬ О. Е. , МЕЛЬНИК А. С.
Published: October 2023

У даній роботі досліджено широко використовувані активні фармацевтичні інгредієнти (AFI) – α-ліпоєву кислоту (ALA) та моксифлоксацин (MF). Володіючи широким спектром лікувальних властивостей та антиоксидантною здатністю, ці інгредієнти під час зберігання за впливу денного сонячного світла втрачають свій лікувальний потенціал за рахунок утворення продуктів фотодеградації та зменшення ефективної лікувальної концентрації. Одним із способів підвищення терміну зберігання біодеградабельних інгредієнтів зі збереженням їх лікувальної активності є інкапсуляція в наноносії, серед яких популярним є нетоксичний біологічно безпечний природний мінерал – галлуазит. В роботі відпрацьовано методику інкапсуляції вакуумним методом в галлуазитні нанотрубки (HNTs) активних фармацевтичних інгредієнтів – α-ліпоєвої кислоти та моксифлоксацину. Отримано нанокомпозитні матеріали на основі нанотрубок галлуазиту та фармацевтичних інгредієнтів – HNTs-ALA та HNTs- MF. Контроль завантаження здійснено ТЕМ мікроскопією. Проведено тестування на фотостабільність отриманих нанокомпозитних матеріалів при денній температурі протягом доби. Фотостабільність індивідуальних компонентів в нативному стані досліджено у складі водної дисперсії HNTs та AFI. Контроль зміни концентрації органічних речовин проводили за допомогою високоефективної рідинної хроматографії. Встановлено, що інкапсульовані активні фармацевтичні інгредієнти у складі галлуазитних нанотрубок є більш стійкими, ніж в нативному стані. Фотодеградація фармацевтичних інгредієнтів під впливом квантів сонячного світла відбувається за рахунок руйнування зв’язків в молекулах органічних сполук з утворенням продуктів деградації. Тестуванням встановлено, що інкапсуляція в галлуазитні нанотрубки може захистити α-ліпоєву кислоту (ALA) та моксифлоксацин на рівні 98,5% 99,9% відповідно. В нативному стані після доби випробувань залишковий вміст α-ліпоєвої кислоти та моксифлоксацину складає 82,0% та 89,0% відповідно.

Authors: ПИСАРЕНКО С. В. , ЧИГИРИНЕЦЬ О. Е.
Published: October 2023

У роботі досліджено фотокаталітичну активність калій титанату, який одержано методом лужного плавлення ільменіту Іршанського родовища (Україна) у відношенні до різних барвників: метиленового синього, який належить до катіонного типу та конго червоного, який є барвником аніонного типу. Фотокаталітичні агенти використовуються для розкладання органічних забруднювачів у водному середовищі за допомогою світла. Одним з сучасних та перспективних методів очистки стічних вод є фотокаталітичний розклад барвників. Даний метод фотодеструкції має ряд переваг, до яких належать: висока швидкість та ефективність процесу, просте та дешеве обладнання, невелика маса фотокаталізатора тощо. В роботі використано калій титанат як каталізатор для процесу фотокаталітичної деструкції барвників метиленового синього та конго червоного в розчинах. Фотокаталіз проведено з використанням УФ-лампи потужністю 40 W (λ = 365–400 нм) при постійному перемішуванні (маса каталізатора – 5 мг, об’єм розчину барвника 20 мл) за температури 293 К. Після досягнення рівноваги каталізатор відділяли від розчину центрифугуванням протягом 5 хвилин за швидкості обертання 1500 об/хв. Концентрацію барвника до та після процесу фотокаталітичної деструкції визначали на спектрофотометрі UV-1200. Визначено часові та концентраційні залежності процесу фотодеструкції барвників метиленового синього та конго червоного в розчинах поверхнею калій титанату. Ступінь фотокаталітичної деструкції барвників (Х, %) розраховано за величинами зміни концентрації до та після опромінення ультрафіолетом розчинів. Виявлено, що фотокаталітична активність калій титанату залежить від концентрації барвника в розчині та часу опромінення. Встановлено, що при 10 хвилинному опроміненні ультрафіолетом реакційної суміші каталізатор-розчин за постійного перемішування при максимальній концентрації метиленового синього 10 мг/л ступінь фотокаталітичної деструкції барвника становить 81,91%. Показано, що на фотокаталітичну деструкцію конго червного калій титанат не впливає в порівнянні з метиленовим синім, що може бути пояснено різною будовою молекул барвників.

La principal tarea de los recién asumidos Gobernadores Regionales, en cuanto son una institución nueva en el sistema público chileno, tiene una elevada complejidad. En efecto, la omnipresencia secular de la cultura centralista y la operación actual de las instituciones nacionales que operan con ese “piloto automático” otorga al centralismo la categoría de “problema perverso” o enmarañado. En este artículo intentamos encontrar los hilos que nos permitan ir desenredando esa madeja, identificando al interior del sistema centralista de gobierno territorial las acciones necesarias para ir generando un nuevo sistema institucional más democrático y eficiente.
El Debate sobre el Estado Social
Authors: Martner Fanta Gonzalo Daniel
Published: October 2023

Este texto presenta algunos de los elementos que forman parte del debate constitucional sobre el Estado Social en Chile. Se reseña brevemente la evolución desde la idea del Estado democrático de derecho a la del Estado democrático y social de derecho y describe el precedente de la Declaración Universal de Derechos Humanos de 1948 y la introducción de la noción de Estado social en la Constitución alemana de 1949. Después, se consignan los tratados principales vigentes en materia de derechos económicos, sociales, culturales y ambientales y describe los elementos en la materia incluidos en la propuesta de la Convención Constitucional de 2022. Finalmente, se discute sobre el costo de introducir los derechos sociales mencionados en esa propuesta, que diversos autores estimaron en 9%-14% del PIB de 2021. Los datos más recientes de la OCDE indican que los gastos sociales representaban en Chile en 2019 un 11% del PIB, situados en el rango más bajo entre los países miembros, mientras los de rango medio se situaban en 19% del PIB y los del rango más alto en 29%-31% del PIB.

El Gran Fracaso del Gradualismo en Venezuela I
Authors: Esteves Arria José Tomás
Published: October 2023

El gradualismo está asociado con el mantenimiento de controles de cambio y precios, mientras que las políticas de choque están ancladas en devaluaciones y liberalizaciones. En el caso de Venezuela, la política económica a largo plazo está enlazada con el gradualismo y, por tanto, el pasado. Se observa que Venezuela ha sido un país sin libertades económicas aceptables donde las políticas de choque se hallan ausentes. En este ensayo, se busca deshilvanar un hilo de las políticas económicas cuales, desde la década de 1980, han impedido dotar una base suficiente a Venezuela para enfrentar su crisis económica.

Authors: Ivars Jorge Daniel , Carballo Hiramatsu Oscar Alberto
Published: October 2023

Describimos la trayectoria de la olivicultura de Mendoza y San Juan en el marco de los distintos Regímenes Alimentarios Internacionales (RAI), enfatizando en los efectos locales de la transición a 3º RAI. La metodología utilizada es la de los estudios de casos y responde a una triangulación de técnicas cualitativas y cuantitativas a partir de fuentes primarias, generadas en terreno, junto a fuentes secundarias. Entre los principales resultados, detallamos las sucesivas vicisitudes que atravesó el complejo agroindustrial en los últimos cien años hasta consolidar el modelo actual moderno pero excluyente. Este modelo se constituyó a partir de un franco proceso de ruptura con el anterior, fundamentalmente en relación a un nuevo paradigma de calidad. Entre las conclusiones resaltamos que la última reconfiguración del complejo catapultó la olivicultura local a los mercados mundiales pero al costo de mayores procesos de concentración y exclusión. Sin embargo, la expulsión de la pequeña producción no solo implica una pérdida en términos sociales, sino también de una oportunidad para la elaboración de productos más complejos y mejor valorados en estos mercados, en función de la riqueza varietal y el know how que la caracteriza.

Chemical features of dark miсas from calcite-nepheline-feldspar pegmatites of the Ilmenogorsky alkaline block (South Urals)
Authors: Cherednichenko S. V.
Published: October 2023

The composition and structure of micas of the annite–phlogopite and siderophyllite– eastonite series in calcite-nepheline-feldspar pegmatites of the Ilmenogorsky miaskite block are studied. The composition of mica of the annite–phlogopite series depends on the formation conditions of pegmatites. The nepheline-feldspar pegmatite with a rock-forming calcite (mine no. 125) contains annite with higher Fe content (Ftot 0.67–0.73). A pegmatite with late calcite (mine no. 16) contains less ferruginous annite (Ftot 0.52–0.63) and phlogopite (Ftot 0.32–0.50). The mica of the annite-phlogopite series exhibits a direct correlation between the Fetotal and Al contents. The mica of the siderophyllite–eastonite series in calcite-nepheline-feldspar pegmatites formed later in assemblage with minerals of the pyrochlore group, baddeleyite, calcite, fuorite, magnetite and Nb-bearing rutile. The Fe content of micas affects the shift of the Raman bands in the studied Samples. Ferruginous siderophyllite, eastonite and their barium varieties are identifed for the frst time for the Ilmenogosrky-Vishnevogorsky complex.

Tuning the flexural frequency of overhang-/T-shaped microcantilevers for high harmonics
Authors: Dat Le Tri , Cuong Nguyen Chi , Duy Vy Nguyen , Payam Amir F.
Published: October 2023

High-harmonic (HH) frequencies in microcantilevers impose several applications in precision detection thanks to the higher sensitivity of the higher modes in comparison to the fundamental modes. In this study, we showed that by tuning the cantilever length by changing the clamped position, the dimensional ratio of the overhang to the main cantilever part is altered and the HHs could be effectively obtained. Multiple HH frequencies have been achieved, from the 4th to 8th order of the second and from the 11th to 26th order of the third-mechanical mode versus the first mode, and these orders are much higher if higher modes are used. The analytical calculation is in agreement with available results of other groups. HH behavior when the cantilever interacts with the sample is also examined and is strongly dependent on the overhang parameters. These results could guide the experimentalist in the tuning and controlling of the HHs in detecting objects.
Rotational Invariant Half Iris Based Person Verification Using Multi Wavelet and SVM
Authors: Das Sayan , Kar Biswajit
Published: October 2023

Iris recognition is widely regarded as an efficient biometric technique due to the uniqueness and persistence of iris features. This recognition system has shown high accuracy and reliability compared to other biometric methods. However, extracting the relevant features from iris images poses a significant challenge. In this experimental research, it is found that fusing multiple wavelet features leads to improved accuracy, compared to using a single feature-based iris verification method. Specifically, support vector machines (SVM) as the classification algorithm is employed in this work. In this study, the accuracy of 19 types of different wavelets is assessed and the performance of the coiflet4 wavelet at the second-level horizontal component is specifically observed, which achieved an accuracy of 91.8%. On the other hand, the lowest accuracy was recorded for the bior1.3 wavelet at the fourth-level horizontal component, with a score of 65.6%. These findings emphasise the importance of selecting appropriate wavelets for achieving greater accuracy. This experimental setup yielded an accuracy of 98.62% for the CASIA database and 97.87% for the UBIRIS database. These accuracies indicate the effectiveness of utilizing multiple wavelet features and SVM-based classification in iris-based person verification. By exploiting the fusion of multiple wavelet characteristics, the recognition system’s ability to distinguish is enhanced, resulting in improved precision and dependability in the verification of individuals based on their iris patterns. The main work of this research is to evaluate the performance of half-iris-based verification. The goal is to address the challenges faced due to occlusion and rotational variations between the reference and test iris images. The analysis focuses on half iris verification with rotational variations of ±5◦,±10◦,±15◦ between the reference and test iris images. For the half iris, the strip size is reduced to 20x120 pixels, reflecting the analysis of only a portion of the iris and creating a more compact representation of its features. Multiple wavelet features and half iris-based person verification using SVM classifier techniques are applied here. The proposed technique for rotational invariant half-iris-based person verification achieves an accuracy of 98.59% for the CASIA database and 97.65% for the UBIRIS database. The half-iris-based verification results are very close to the full-iris-based verification results. The overall verification accuracy is far better compared to the reported results. The maximum verification accuracy reported for the CASIA database is 96.13%, whereas, we have achieved 98.59% accuracy for half iris with less number of features.
AI-Native Multi-Constraint Routing System and Method
Authors: Prihodko Maxim , Das Biswarup , Krantsevich Artem , Rakhimov Abdurasul , Vasilenko Eduard
Published: October 2023

The problem of multi-constraint routing is related to Multi-Objective Shortest Path Problem (MOSPP) and is known to be NP-hard. Despite decades of research, there is no state-of-the-art solution for this problem as Dijkstra algorithm for the single constraint case. This paper develops a systematic strategy to construct a model of an IP Network with multiple weight links and proposes a scalable and generalized AI-Native routing system and method (MORAI) to synthesize a composite cost to achieve optimal routing plane computation for multiple QoS-demands. The proposed method consists of an AI model and the training procedure and considers composite cost synthesis as an optimization process maximizing the number of feasible routes (satisfying multiple QoS-demands) in the Shortest Path Tree constructed with the composite cost as an edge weight. Using a composite cost for route identification with a Shortest Path First Algorithm guarantees that the routing is loop-free and fully distributed. The proposed system architecture is a combination of distributed and centralized modes. When the AI model is trained in a dedicated device, the following route computation is fully distributed, so the solution can be easily deployed in the current router architecture. Three system architectures are proposed, showing different combinations of AI-model training, execution, and composite cost computation in the network. Finally, the general paradigm of AI-Native Composite Cost synthesis is described, as well as the general AI model training scheme design is given. 
Navigation Antenna Pattern Retrieval after Measurement under Directed Irradiation from a Close Distance
Authors: Abuhadma Layth
Published: October 2023

Currently, interest in the prospects for practical implementation of methods that allow retrieving the true radiation pattern when irradiating the navigation antenna under test from an insufficiently large distance is noticeably growing. The use of directed radiation in this case, on the one hand, reduces the level of reflections from the walls of the chamber, but on the other hand, increases the heterogeneity of the irradiating field. The paper aims to elucidate the influence of the directed properties of the auxiliary antenna, which forms the irradiating field, on the measurement process and the accuracy of the radiation pattern retrieval, under the condition that both of them are by the methodology of a converging cluster of plane waves. Simulating measurement and data processing were carried out when the size of the auxiliary antenna varied. The simulation results confirm that the reconstruction accuracy is practically independent of the nature of the irradiating field.

Published: October 2023

Rydberg atom receivers have the potential to supple- ment or replace traditional sensing technologies due to the high sensitivity, unconventional detection mechanisms, and unusual responses they can provide. Given the importance of angle of arrival (AOA) estimation for geolocation and the potential impact of these technologies more work is needed to understand the Rydberg sensor’s impact on AOA estimation. While there have been many experimental and theoretical efforts to improve the sensitivity and bandwidth of these quantum sensors, few papers have explored the impact that these technologies will have on AOA estimation. This paper presents a numerical study of AOA estimation using a simulated linear array of Rydberg atom re- ceivers consisting of vapor cells with laser-defined sense volumes. By utilizing atomic physics and electromagnetics simulations, we show that uncompensated atomic transient effects and RF dispersion in glass vapor cell arrays can substantially degrade AOA estimation.

Sound source localization with multi-feature fusion using residuals and channel attention
Authors: Agarwal Nipun
Published: October 2023

Recent advances in deep learning have enhanced the ability of sound source localization in noise and reverberation. However, the single feature input and relatively simple network design hinder the further improvement of such ability. Therefore, a multi-feature fusion sound source localization method is proposed based on residuals and channel attention. The strategy of multi-feature fusion provides a deep neural network with more comprehensive discriminative features. The deep neural network fully extracts the sound source location information from the fused features by introducing residuals and channel attention. The simulations show that the localization accuracies of the proposed method in single and multiple sound source scenarios are respectively 8.24% and 15.54% higher than those of the single feature convolutional neural network (SF-CNN). In addition, the proposed method has excellent performance under different signal-to-noise ratios and reverberation times, which verifies its robustness to noise and reverberation. In the experiment, the proposed method is still effective in localizing single and multiple sound sources, and its localization accuracies are 5.48% and 7.57% higher than that of SF-CNN. With high accuracy and strong robustness, this method is significant for sound source localization in complex environments, such as noise, reverberation, and the presence of multiple sound sources.

Nipah virus disease outbreak occurred in Kerala in the month of May 2018. It happened in Kerala again in September 2023. As on 13th September 2023, two unnatural deaths from Kozhikode district were suspected to be due to Nipah virus infection. Again in Sept 14, 2023, TOI reports that Kerala reported its 5th case. In the absence of a definitive cure for this viral disease, the article peeps through the homoeopathic lens & explores what it can offer to deal with this viral episode. The success of homoeopathy in COVID 19 again reiterates the fact that as homoeopathy was & is effective against viral infections; it is effective against Nipah virus disease also [2]. Nipah virus is an enveloped RNA virus that has been a major cause of encephalitis outbreaks with high mortality primarily in the Indo-Bangladesh regions. The first breakout was in Malaysia-Singapore that was related to contact with pigs & the outbreak in Phillipines associated with horse slaughter. Most other out breaks has affected the Indo- Bangladesh regions. Here, the outbreaks were associated with consumption of raw date palm sap contaminated by fruit bats & had a very high secondary attack rate [3].

Published: October 2023

One of the most typical malignancies in males is prostate cancer, and its global burden is increasing. Using text-mining technology, this study seeks to pinpoint important genes and biochemical processes related to prostate cancer. Using certain terms related to gene expression, PUBMED abstracts of interest were found. The extracted abstracts included gene pairings and functional connections. On the genes identified from the function interactions, biological procedures enrichment, network analysis, and gene prioritizing utilizing edge centrality of betweenness were carried out. For the modules containing at least five genes, which were retrieved from the network analysis, gene clustering and pathway enrichment analyses were built. The biological functions of the newly identified genes showed that they were involved in positive transcriptional regulation from the RNA polymerase II promoter, positive regulation of cell proliferation, and drug responsiveness. The prostate cancer enrichment analysis processes revealed that the NF signalling pathway, PI3k-Art signalling pathway, thyroid hormone signalling, and ErbB signalling pathways were enriched. According to the network analysis results, which were further sorted by their values for degree of between-ness, it was discovered that AKT1, AR, and KDM3A were the important genes. In conclusion, by concentrating on the discovered hub genes, prostate cancer can be medically treated.

Normocalcemic primary hyperparathyroidism (PHP) has been proposed to be a new phenotype of the disease. It is characterized by persistently high levels of parathyroid hormone (PTH) and normal calcium levels. Since there are no known causes of secondary hyperparathyroidism or PTH elevation, the exact biological mechanism is not known. It could be the first stage of the disease or a unique situation marked by resistance of the kidneys and bones to the effects of PTH. This is a disease that is getting more and more common. It is often found when evaluating perimenopausal women with low bone mass or when evaluating or following up on patients with osteoporosis. Normocalcemic PHP has a diverse and varied phenotype that ranges from cases with no usual PHP symptoms to cases with symptoms and specific complications. The method to diagnosing secondary hyperparathyroidism should focus on ruling out all possible causes, especially vitamin D deficiency (25-OH vitamin D levels less than 30ng/mL) and kidney function impairment (glomerular filtration rate less than 60 mL/min, as measured by CKD- EPI). Not much is known about its past in the wild. Some people get hypercalcemia, but more than 75% of them don't. There don't seem to be any ways to predict who will get hypercalcemia, so measuring total and adjusted calcium levels once a year is recommended. Even though measuring ionic calcium is a part of what it means to have Normocalcemic PHP and is recommended by some writers during follow-up, there are a number of real problems with it that should be kept in mind.
Pulpit Interpretation in the Cameroon Baptist Convention Churches
Authors: Ndem Ndi Eunice
Published: October 2023

This article examines how the Cameroon Baptist Church (CBC) makes efforts to pass across the gospel message to their target population through sermon interpreting. It highlights how interpretation of sermons are carried out by lay interpreters given the necessity of interpretation in bilingual congregations. The two languages concerned are French and English, the two official languages of Cameroon. The linguistic nature of Cameroon obliges the CBC to organize bilingual church services so as to minister alternately to their bilingual audience. While interpreting is necessary and obligatory given the target church population, the problem is the quality of interpretation due to unskilled interpreters that sometimes misinterpret messages leading to break down in communication. Break downs in sermon interpretations can really be misleading because the word of God is Yes and Amen. It is therefore concluded that given the centrality of interpreting in the CBC settings, it is important for the CBC to train interpreters and make use of them for the well being of evangelism.

As avaliações forenses podem envolver a amostragem de fibras têxteis ao examinar cenas de crime. A necessidade de caracterizar e identificar essas fibras é de grande importância, pois elas podem fornecer informações abrangentes sobre um crime, ligando um suspeito a um local, com base em características como comprimento, diâmetro e, particularmente, a composição das fibras. A micro espectroscopia de infravermelho com transformada de Fourier em modo de refletância total atenuada (micro FTIR-ATR) é considerada um método não-destrutivo, rápido e prático na identificação de fibras. Neste estudo realizamos uma avaliação forense de sessenta fibras têxteis recuperadas de vinte tecidos, todos com coloração branca, via análise de micro FTIR-ATR. A coleta das fibras foi feita com base no método de levantamento de fita, a fim de simular uma coleta em cena real de crime. Os dados foram plotados em uma análise bidimensional de componentes principais e em gráfico de radar para favorecer a comparação da composição dos materiais. Os resultados dos espectros de infravermelho revelaram que a técnica permite a discriminação de fibras têxteis de acordo com sua composição espectral (celulose, éster, poliéster ou mistura desses compostos) e algumas características, como número e largura de picos, posição do pico de acordo com o número de onda, índice de absorbância relacionado à nitidez do pico. Concluiu-se que a técnica foi útil e prática na avaliação forense das fibras, apresentando resultados rápidos e esclarecedores.

The frequent human errors while driving causes awful events ending up in significant amount of road accidents. Today's traffic forums insist drivers to pay careful attention to the traffic signals that are simultaneously notified through the different sources. The two of the major effects of reckless driving are increased traffic and fatalities. More accidents occur as a result of common errors made by people, such as talking on the phone or playing loud music while driving. Automated traffic detection and real-time monitoring may significantly enhance and assist the driving safety. The usage of automated traffic detection and real-time monitoring is more important nowadays, as technology is seeking for automation in every area. The potential of autonomous vehicles to travel on highways and roads offers people with a wide range of opportunities, from improving traffic safety to fundamentally altering the way a person gets about. Additionally, the recent increases in accidents, which have been connected to both an increase in the number of automobiles on the road and negligent driving on the part of drivers, it appears that owning a car is now necessary. Self-driving cars have the ability to sense their surroundings as it is enabled with the LiDAR, Radar, GPS, and cameras. Autonomous cars' main benefit is their decreased risk of accidents. If these vehicles are widely available and well-engineered, their reduced fuel use could help in reducing the pollution. The pre-installed features including lane identification, obstacle recognition, and traffic sign detection, enables the car to go independently from one place to another. This review article may be used as a quick guide for professionals experimenting with self-driving cars with various technologies.

Приведены результаты исследования отдельных компонентов водной и околоводной экосистем Воронежского водохранилища. Отбор проб проведён в точках, приуроченных к основным мостам на правом и левом берегах. Приведены результаты оценки органолептических свойств воды. Выполнен химический анализ проб воды с определением уровня рН, общей жёсткости, содержания ионов кальция, железа, бикарбонатов, сульфат-ион, нитрат-ион. Установлено, что по большинству показателей вода не превышает значений ПДК. Описаны результаты биотестирования с оценкой общей токсичности на тест-культуре хлореллы и генотоксичности в тесте Эймса. Проведенные биотесты показали, что все пробы воды и почвы проявляют токсические эффекты как стимулируя, так и угнетая рост хлореллы в разных пробах. Отмечено содержание генотоксических соединений в почве и растениях на обеих штаммах сальмонелллы.

In this article we present the results of the study of individual components of the water and near-water ecosystem of the Voronezh water reservoir. Sampling was carried out at points associated with the main bridges on the right and left banks. We present the results of the assessment of the organoleptic properties of water. We performed chemical analysis of water samples to determine pH level, total hardness, content of calcium ions, iron, bicarbonates, sulfate ion, nitrate ion. It was found that for most indicators, water does not exceed the ambient air standard. Here we describe the results of biotesting with the assessment of total toxicity on the chlorella test and genotoxicity in the Ames test. The conducted bioassays showed that all water and soil samples exhibit toxic effects both stimulating and inhibiting the growth of chlorella in different samples. We noted genotoxic compounds in soil and plants on both strains of salmonella.
