Published: December 2024

The validation of analytical methods for Bisoprolol
Fumarate, a widely used beta-blocker for managing
hypertension and heart failure, is crucial to ensure
the drug's quality and efficacy. This study focuses
on validating two key analytical techniques:
Ultraviolet (UV) spectrophotometry and HighPerformance Liquid Chromatography (HPLC). The
research aims to assess the performance, reliability,
and accuracy of these methods for Bisoprolol
Fumarate quantification.The UV
spectrophotometric method involves the
determination of Bisoprolol Fumarate’s absorbance
at a specific wavelength. The study optimized
parameters such as the wavelength of maximum
absorbance and concentration ranges. Validation
included assessing linearity, accuracy, precision,
and limit of detection (LOD) and quantitation
(LOQ). The method showed excellent linearity with
a correlation coefficient (R²) exceeding 0.999,
indicating a high degree of accuracy. Precision
studies demonstrated low relative standard
deviations (RSD), ensuring repeatability. Accuracy
was confirmed through recovery experiments,
which yielded results within the acceptable range.
The LOD and LOQ values were found to be
sufficiently low, confirming the method's
sensitivity for detecting Bisoprolol Fumarate.The
HPLC method involved developing a
chromatographic system with appropriate column,
mobile phase, and detection conditions. The study
used a C18 column with a mobile phase consisting
of a mixture of acetonitrile and phosphate buffer,
optimized for separation and peak resolution. The
detection was carried out at 220 nm. Method
validation focused on parameters such as
specificity, linearity, precision, accuracy,
robustness, and system suitability. Specificity was
ensured through the absence of interference from
excipients and degradation products. The method
demonstrated linearity with a correlation coefficient
of 0.9995, and precision was confirmed with RSD
values below 1% for intra-day and inter-day
analyses. Accuracy was validated through recovery
studies, yielding results close to the theoretical
values. Robustness testing indicated that slight
variations in method parameters did not
significantly affect the results, demonstrating the
method’s reliability under varied conditions. The
HPLC method also achieved low LOD and LOQ,
ensuring its suitability for routine analysis

Authors: Madhumitraa P Madhumitraa P , Sangamithira SK Srimathi , Nikhitha KV Nikhitha KV , Harini Sri V Harini Sri V , Faheema Noufin , Akshaya A Akshaya A
Published: December 2024

Primary Amoebic Meningoencephalitis (PAM) is
an infrequent but highly lethal infection caused by
Naegleria fowleri, a free-living thermophilic
amoeba found in mild freshwater ecosystems.
N.fowleri reaches the human body by the nasal
passages, commonly during swimming, diving or
any other freshwater activities and subsequently
migrates to the encephalon via the olfactory nerve,
leading to rigorous inflammation and tissuedamage. The primary symptoms of PAM resemble
bacterial meningitis, including headache, fever,
nausea and vomiting, which may lead to noetic
status, seizures, and coma. Diagnosis is diificult
due to the infrequency of the condition and the
non-specificity of symptoms, frequently leading to
delayed or missed diagnoses. Laboratory
verification is achieved through cerebrospinal fluid
(CSF) analysis, where the presence of motile
trophozoites is indicative of the infection. Despite
advancements in diagnostic methods, the prognosis
remains bad, with most cases resulting in death
within days of symptom onset. Current treatment
options are inhibited and largely ineffective, with
an amalgamation of Amphotericin B, Rifampicin
and other antimicrobials offering the best but still
dubious chances of survival. The review highlights
the desideratum for incremented vigilance, early
detection, and the development of more efficacious
therapeutic strategies to combat this devastating
disease. Preventive measures, including eschewing
warm freshwater activities and utilizing nasal
discerner clips, are crucial in minimizing the
jeopardy of exposure to N.fowleri. This
comprehensive review aims to provide insights into
the epidemiology, pathogenesis, clinical
presentation, diagnosis, treatment, and obviation of
PAM, accentuating the critical desideratum for
further research in this field.

Published: December 2024

The real-time images captured by agricultural machinery on-board monitoring equipment have complex backgrounds and different shooting angles. Especially for straw monitoring tasks, the utilization rate of images is relatively low. This paper presents a novel image classification and effective region segmentation method for straw returning in agriculture, leveraging semantic segmentation to enhance the efficiency of agricultural data analysis. The study addresses the challenges of manual straw cover analysis by proposing an automated approach to select images that meet monitoring standards. The methodology employs an encoder-decoder structure model, enriched with residual units, multi-scale convolution, and attention mechanisms. This model classifies images by calculating the pixel proportions of various scene categories and segments farmland areas to be inspected by incorporating distance information. The model's design is tailored to handle the complex and variable natural environments typical of vehicular monitoring scenarios, where semantic object boundaries can be fuzzy. The experimental results demonstrate that the proposed method achieves an overall sample classification accuracy of 93% for straw returning image classification and an 85.37% accuracy in dividing areas to be inspected. The method outperforms several mainstream semantic segmentation models, providing a more accurate and efficient means of processing agricultural monitoring images. The integration of distance information proves particularly beneficial in distinguishing the farmland areas under inspection, leading to clearer segmentation and more reliable data for agricultural decision-making. In conclusion, the study contributes to the field of agricultural intelligence by offering a robust method for image analysis that can be applied to optimize the use of straw return monitoring data.

Published: December 2024

This paper focuses on the lack of spherical-like soybean simulation parameters when guiding the optimization and design of agricultural machinery and equipment through discrete element simulation. The spheroidal soybean variety SN29 was used as a study subject; the intrinsic properties and physico-mechanical properties of the spherical soybean were determined through actual measurements and the simulation of spherical-like soybean particles with Hertz-Mindlin (no-slip) as the contact model was established. The collision recovery, static, and rolling friction coefficients of the spherical-like soybean and acrylic sheet material were measured by the natural drop and inclined plane methods, combined with discrete element simulation and bench experiments. They were 0.474, 0.496, and 0.0361, respectively. The relative errors between the measured stacking angles and the simulated stacking angles were used as indicators, and the contact parameters between the particles were used as variables for the design of the steepest climb experiment. The collision recovery coefficient, static friction coefficient, and rolling friction coefficient between spherical-like soybean particles were determined to be 0.35, 0.30, and 0.074, respectively, by orthogonal rotational combination experiment and multi-objective optimization. The relative error between the simulated and measured stacking angles was only 1.09%, as verified by the experiment. This proves that the discrete element simulation parameters of the studied spherical-like soybean can reflect its real characteristics and be used as the parameter basis for discrete element simulation.
Synthesis of cubic-Li7La3Zr2O12 solid electrolyte for all-solid-state lithium-ion batteries via a combination process of induction thermal plasma and calcination
Authors: Min Byeong-Il , Wang Yiran , Tanaka Manabu , Watanabe Takayuki
Published: December 2024

A combined process enabled the selective synthesis of cubic- and tetragonal-Li7La3Zr2O12 with calcination for nanoparticles synthesized by induction thermal plasma. The effect of O2 partial pressure was investigated by adjusting O2 content within a constant sheath gas flow for plasma-synthesized nanoparticles prepared for calcination. Low O2 partial pressure led to spherical nanoparticles from the liquid mixture via homogeneous nucleation of ZrO2, while high O2 partial pressure produced irregular, highly aggregated particles from a liquid-solid mixture with homogeneous nucleation of La2Zr2O7. The rapid quenching rate induced amorphous-Li7La3Zr2O12, and higher O2 promoted slight crystallization to cubic-Li7La3Zr2O12. This result includes potential for the facile production of ultra-thin cubic-Li7La3Zr2O12 films suitable for all-solid-state lithium batteries.

DIMENSIONAMENTO DE FILTRO DE TAMBOR ROTATIVO A VÁCUO: APLICAÇÃO NA FILTRAÇÃO DE CARBONATO DE CÁLCIO
Authors: Coelho André Fernandes , Valente Marina Oliveira , Carvalho Fernanda Raquel
Published: December 2024

Este artigo teve como objetivo o dimensionamento de um filtro de tambor rotativo a vácuo industrial, a partir de dados obtidos no livro de Massarani (2002) sobre um teste de laboratório de filtro-folha, para a obtenção de carbonato de cálcio. O filtro de tambor rotativo a vácuo é utilizado na separação de sólidos insolúveis de uma suspensão, denominada licor-mãe, sendo responsável por remover, secar e descarregar esses sólidos em forma de torta. Esse tipo de filtro é amplamente considerado um dispositivo de separação líquido-sólido bastante versátil. O processo consiste em um tanque contendo o produto a ser filtrado, no qual o tambor, parcialmente submerso, gira e passa pelo lodo. O vácuo extrai o licor, prendendo as partículas sólidas na superfície do tambor e formando a torta. O ensaio de filtro-folha, realizado em laboratório, permite a obtenção de dados fundamentais para o dimensionamento do filtro rotativo a vácuo, como tempos de ciclo de filtração, especificações da torta e pressão em relação ao vácuo. Com os resultados desse ensaio, foi possível aplicar as equações básicas necessárias para calcular os parâmetros operacionais e determinar a área ideal do filtro, que atendesse à vazão requerida do filtrado. Com esses dados em mãos, todas as demais dimensões do filtro rotativo foram determinadas com base no catálogo da empresa Andritz, garantindo a eficiência e a capacidade do equipamento para atender às demandas de produção. Este estudo contribui para a melhoria dos processos de filtração industrial, otimizando o uso de recursos e proporcionando uma base sólida para o desenvolvimento de novas aplicações em indústrias que necessitam de uma separação eficiente entre sólido e líquido.

Leibniz e a Criação da Numeração Binária
Authors: Zandonade Tarcisio
Published: December 2024

This research was motivated by a citation found in Explanation de l'arithmétique binaire, Leibniz’s seminal work on the binary number system. This citation references the correspondence between Bouvet and Leibniz in which they speculate about the existence of traces of binary arithmetic in Chinese culture. After being retrieved from the “Leibniz-Bouvet Correspondence” website, identified from A to O, these fifteen (15) letters were translated from English to Portuguese. The main actions, theories and opinions of the two correspondents were investigated. In Letter H, Leibniz presents his discovery of binary arithmetic to Bouvet, explaining it in detail. Here he discusses the theory that, in the dual system, One (1) represents God, and Zero (0) represents Nothing, thus being an image of divine Creation ex nihilo (imago creationis). In response, in Letter I, Bouvet describes the parity between binary arithmetic and the characters of the I Ching, explaining that Leibniz's table of binary numbers corresponds entirely to the gua, similar to the whole (––) and broken (– –) lines of the I Ching; and suggests an extension of the table from 32 to 64 gua, as in the I Ching. The Chinese characters of the I Ching are explained by Bouvet, who believes them to be derived from Egyptian hieroglyphics. The series of letters bring other information relevant to Leibniz’s work like the introduction of the concept of ‘Characteristica Universalis’ and the monad (Letter L) and the report on the progress of the development of the binary system (Letter M and O). The originality of this research consists in the translation from English to Portuguese of all correspondence between Leibniz and Bouvet and the initial analysis of the similarities between the concepts developed by Leibniz in Europe and the I Ching of traditional Chinese culture. This work can trigger further research, especially on the ‘organization of knowledge’ proposed by Leibniz, and the similarity between his universal encyclopedia and the Internet.

Methodology for determination of the rational operating time of a piston hybrid energy machine of volumetric action with regenerative heat exchange in compressor and pump mode
Authors:   Shcherba V.E. Nosov E.YU.
Published: December 2024

A method is developed for determination of the rational operating time of a piston hybrid power volumetric machine with regenerative heat exchange in compressor mode while ensuring of maximum indicator coefficient of efficiency for the full operation cycle and maximum supply coefficient. With the assumption that the cooling time is linearized from the heating time, it is established that in order to obtain maximum indicator coefficient of efficiency it is necessary to reduce the operating time and the temperature of the cylinder-piston group should be minimal. It is shown that the optimal operating time in compressor mode at maximum coefficient of efficiency, taking into account the switching time, increases, and when the indicator coefficient of efficiency decreases, it decreases.

Анализ показал, что большинство гибридных сеянцев сливы характеризуются средним сроком созревания. За весь период наблюдения ни одного сеянца с поздним сроком созревания выявлено не было. Более того, наблюдалась тенденция к ускорению созревания плодов у гибридов по сравнению с исходными сортами. Результаты этого исследования имеют важное значение для селекционеров, занимающихся выведением новых сортов сливы с улучшенными качествами, в том числе, ускоренными сроками созревания. Это позволит увеличить урожайность и расширить географию возделывания данной культуры.

O presente estudo teve como objetivo analisar os aspectos psicomotores de crianças com Transtorno do Espectro Autista (TEA) durante e após o isolamento social provocado pela pandemia de COVID-19. Trata-se de um estudo qualitativo, fenomenológico e exploratório, conduzido com 18 participantes, sendo 9 tutores legais de ambos os sexos e 9 crianças do sexo masculino com idade entre 4 a 11 anos, cadastrados no centro de reabilitação pesquisado, com diagnóstico fechado de TEA, de diversos níveis de suporte. Os dados foram coletados por meio do instrumento próprio de pesquisa, baseado na Bateria Psicomotora Vítor da Fonseca (BPM). Como resultado, 4 aspectos dos 7 existentes na BPM, foram os mais citados e observados pelos tutores legais, durante e após o período do isolamento, sendo eles a equilibração, lateralização, noção do corpo e praxia global. Os achados expressos no quadro, sugerem que o isolamento social foi um fator agravante para a realização de aspectos psicomotores como equilibração, lateralização e noção do corpo, seja durante ou após o período em questão, mas a maior parte dos tutores legais não demonstraram conhecimento das habilidades das crianças e do diagnóstico de TEA.
O biógrafo e o biografado, entre as fontes e o encontro: relações entre História Oral e História Pública na escrita biográfica
Authors: Moreira Igor Lemos
Published: December 2024

Nos últimos anos, a ideia de colaboração e de relação dialógica entre pesquisador e sujeitos de pesquisa tem se tornado um dos pilares do movimento da História Pública. Tal dimensão tem provocado renovações epistêmicas e movimentos de autorreflexividade potentes para a operação historiográfica, de modo a permitir uma reflexão sobre a prática e, em especial, a respeito das ações que constituem o “fazer historiográfico”. Reconhecendo tal potencialidade, o presente trabalho visa apresentar um conjunto de reflexões, inquietações e impressões de pesquisa no campo da biografia e da história oral a partir da abertura para o diálogo com sujeitos vividos assumidos não como “objetos”, mas interlocutores de pesquisa. Toma-se, em particular, como ponto de partida a experiência de construção de uma biografia histórica da cantora cubana Gloria Estefan como uma tese de doutoramento a partir da possibilidade de entrevista com a artista. Procura-se explorar as dimensões éticas, colaborativas e renovadoras de tais experiências, que transitam entre a teoria, a metodologia e a construção narrativa. Enquanto argumento, o ensaio compartilha um conjunto de reflexões acerca dos impactos que emergem ao abrir-se a possibilidade de construção de uma biografia em colaboração com sujeitos vivos, sendo neste caso em colaboração com a própria biografada.

Published: December 2024

As análises delineadas neste texto visam refletir sobre como as entrevistas públicas foram realizadas de maneira interativa para proporcionar momentos de formação de professores, com base nas ideias desenvolvidas na história pública. Como referencial teórico-metodológico optamos pela história oral em conjunto com a história pública para analisar as trajetórias de vida das professoras sob uma perspectiva sócio-histórica, com base em Santhiago (2016) e Cauvin (2016). Os estudos de Pranto, Sulaiman e Almeida (2023) e Goodson (2022) foram fundamentais para traçar discussões acerca do caráter formativo das narrativas docentes. As entrevistas públicas foram conduzidas de forma dialógica, permitindo a participação do público na construção das narrativas. As entrevistas públicas foram construídas a partir das discussões e reflexões acerca do entrelace da história oral e história pública, que nos permitiram uma visão e construção dialógica e colaborativa. Essa prática evidencia o caráter formativo das entrevistas, enfatizando a necessidade de compartilhar e valorizar as experiências dos professores dentro da comunidade escolar.

The aim of the study is to investigate the effect of rations with different preparation of the concentrated part on the productivity and quality of milk in dairy cows of the Red Steppe breed, in the Orenburg Region. Objectives: to analyze the formation of the productivity of cows of the accounting period of lactation (gross milk yield, daily milk yield, milk composition, economic efficiency) depending on the method of preparing the concentrated part of the cows' ration. According to the developed research methodology, the conditions of keeping and feeding were identical. The structure of the ration of the control group of animals included: cereal hay – 15.2 %; legume – 14.7; corn silage – 31.9; crushed grain mixture (barley + wheat) – 34.5; sunflower cake – 3.7 %. In two experimental groups with the same structure, the crushed grain mixture was replaced by cavitated grain mixture (Group I) and cavitated wheat bran (Group II) in terms of nutritional value. Feeding dairy cows with rations containing cavitated concentrates had a positive effect on milk productivity and quality. The actual yield of natural milk during the experimental period (182 days) increased by 23.0 and 26.1 %, respectively, compared to the control. The increase in net income per animal from the sale of commercial milk amounted to 3902.7 and 4380.0 rubles, while profitability increased by 5.9 and 6.6 %, respectively.

The aim of the study is to identify the intensity and extensiveness of the invasion among fish and dogs. Objectives: to identify the intensity and extensiveness of the invasion among fish and dogs in the Barguzinsky District of the Republic of Buryatia; to study the spread of diphyllobothriasis in the Barguzinsky District of the Republic of Buryatia; to study the effectiveness of anthelmintic drugs used to treat the invasive disease. The studies were conducted during 2021–2023 at the FSBEI HE Buryat State Agricultural Academy named after V.R. Filippov. Diagnostic studies were carried out, the epizootological situation for diphyllobothriasis in fish and dogs was studied, the most effective anthelmintic drugs were identified. The object of the study was three species of fish (Siberian roach, pike and perch) caught in the Barguzin River, as well as dogs. The results of research showed that the Siberian roach, perch and pike are infested with the pathogen Diphyllobothrium Dendriticum (gull tapeworm). At the same time, the extensiveness of the invasion in the Siberian roach, pike and perch was 63; 60 and 70 %, respectively, while the intensity of the invasion was 2.84; 3.33 and 13.00 plerocercoids, respectively, in each fish species. Studies of dogs with diphyllobothriasis showed that the prevalence of the infestation was 75 %. The infested animals were divided into three groups: two experimental and one control. The dogs were drowsy, had no appetite, and were losing weight. In the first experimental group, the dogs were treated with Prazitel Plus (suspension), in the second group – with Inspector Quadro Tabs, and the dogs in the control group were not treated. The study showed that the anthelmintic drugs Prazitel Plus and Inspector Quadro Tabs are effective. In the coastal zone, it is necessary to carry out a set of measures to prevent and eliminate diphyllobothriasis in carnivores. Particular attention should be paid to preventive talks with the population of the area about not allowing raw or poorly processed fish to be eaten by people or fed to carnivores.

The aim of the study is to assess the response of winter rye (Secále cereále) and its varieties to changes in soil and climatic conditions in the Republic of Bashkortostan. Statistical data on winter rye yields in 2012–2021 in 54 municipal districts and the results of field experiments conducted in 2018–2022 in 4–5 farms and 7 variety plots were used. The response of winter rye was assessed by calculating the yield variation coefficient, parameters of environmental plasticity and stability, yield range and stress resistance. According to the study results, the territory of the Republic of Bashkortostan is characterized by a variety of soil and agroclimatic resources for the formation of winter rye yields. The range of variation of the environmental conditions index in the republic is from –13.71 to +10.92. Winter rye reacts significantly to spatial variability of soil and climate conditions (84.03 % yield dispersion), which is ultimately reflected in grain yield. The degree of reaction of winter rye, as a type of cultivated plant, to changes in external conditions depends on its varietal composition. Winter rye varieties respond to changes in the conditions of plant growth and development to varying degrees. The winter rye hybrid KVS Aviator reacts most strongly to changes in soil and climatic conditions. The yield variation coefficient of this hybrid is 25.62 %, the standard deviation of yield from the theoretical is 10.73, and the ecological plasticity index is 1.12. The response of the population varieties Pamyati Kunakbaeva and Chulpan 9 to growing conditions is almost the same. The response to stressful vegetation conditions in the winter rye variety Chulpan 9 and the KVS Aviator hybrid is the same, while that of the Pamyati Kunakbaeva variety is slightly lower.
THE ACTIVITY AND ROLE OF THE CLERK IN THE ALIEN DEPARTMENTS OF THE SOUTH OF THE YENISEI PROVINCE 1823−1893
Authors: Samrina Elena
Published: December 2024

The paper examines the activities of one of the key figures in the self-government of non-Russians – the clerk, who informally had broad powers in various areas of public life. The position of clerk in non-Russian departments was introduced in accordance with the "Charter on the Management of Non-Russians" of 1823. Due to the need for written office work, an office staff was created, consisting of a clerk, several assistants and ulus clerks. Formally, the job responsibilities of the clerk included maintaining written office work: drawing up sentences and decisions of the non-Russian court, writing responses to circulars from the district authorities, compiling various population and welfare records; reports on the collection of taxes and payments. In practice, clerks were assigned all office work with documents related to the activities of the departments. They were part of the management of the non-Russian self-government bodies, had influence both on the election of officials and on the procedure for their dismissal. Due to the illiteracy of the founder and the bashlyks, it was the clerk who managed the Duma treasury and often used his position as a source of enrichment. The clerk, abusing his position, established and collected yasak from society, wrote fictitious sentences. Often, being the only literate member of the alien department, he drew up business papers: complaints, petitions, which further increased his weight and influence in the eyes of the surrounding population. A significant part of the Duma budget was directed to the maintenance of the clerk due to the necessity and importance of this position both in the system of state power and in the life of the foreign society.
