Published: December 2023

The purpose of separation of seed mixtures is the most complete separation of fractions according to the characteristics that ensure the required quality of the resulting final product with the least number of operations. These features are taken into account when creating schematic diagrams of grain-cleaning and sorting machines (separators). Presented the results of a study to determine the indicator for assessing the technological effect of separation by the example of separation of seed mixtures in the ascending air flow of pneumatic sorting machines. (Research purpose) The research purpose is developing a method for calculating the indicator for assessing the technological effect of separation on the separation of seed mixtures in the ascending air flow of pneumatic sorting machines. (Materials and methods) Conducted a study based on the logistician equation and methods of mathematical statistics. (Results and discussion) We considered the logistic equation (the Ferhulst equation by the name of the Belgian mathematician who first formulated it), which initially appeared when studying the population growth model. It was established that the result of measurements of the physico-mechanical properties of seeds (signs of separation) is expressed either in variational series or in variational curves that determine the frequency of a particular seed size of any aggregate. It was shown that from the comparison of these data obtained for each component separately, it is possible to identify which sizes of the main grain are the most different in comparison with those of the impurities. (Conclusions) We obtained a formula for evaluating the technological effect of separation by the example of separation of seed mixtures in the ascending air flow of pneumatic sorting machines, characterized in that it takes into account the soaring speed of the separated components as a sign of separation.

Published: December 2023

Magnetic fluids are an artificial material that is characterized by fluidity and the ability to be strongly magnetized in magnetic fields. They consist of colloidal particles of a ferri- or ferromagnet, a carrier liquid medium and a surfactant. (Research purpose) The research purpose is determining the parameters of magnetic fluids for the developed electric pulsator. We chose a magnetofluidic seal for the sealing unit in the new design of the electric pulsator of the milking machine; the magnetofluidic seal assembly holds the rod of the linear electric motor in a strictly axial position, excluding distortions, locking and vibration, which ensures stable performance of the specified milking mode. (Materials and methods) It was shown that the developed magnetofluidic sealing unit is located in a groove filled with magnetic fluid. It was determined that the leakage of magnetic fluid in the groove excludes a toroidal permanent magnet limited by a retainer. A suspension of highly dispersed magnetite particles in kerosene stabilized with oleic acid was used in the developed magnetofluidic compaction unit. (Results and discussion) Experimental dependences of magnetization on the magnitude of the applied magnetic field, as well as the coefficient of thermal conductivity on temperature, were obtained for three samples of magnetic fluid with different concentrations of the solid phase. It was found that all samples have a linear dependence of magnetization up to the values of the external magnetic field strength of about 35 kiloamps per meter. It was found that the saturation magnetization of the magnetic fluid increases from 21 to 24 kiloamps per meter with an increase in the concentration of the magnetic phase from 8 to 12 percent in the samples. It was established during the calculation that the pressure drop that the developed unit withstands is from 104 to 106 pascal. It was theoretically proved that the critical pressure drop increases with a decrease in the gap between the rod and the retainer. (Conclusions) Three samples of magnetic fluid were studied and hydrodynamic, thermophysical and other parameters of magnetic fluids potentially applicable for their use as seals in the nodes of the magnetofluidic seal of the developed electric pulsator were determined.

The global trend in the development of dairy farming is aimed at automating and robotizing the technological processes of milk production on a commodity farm. (Research purpose) The research purpose is developing a system for assessing the fatness score of dairy cows, which will be applicable for machine vision systems and will automate early diagnosis of the physiological state, prevention of disease development, adjustment of the feeding diet, decision-making on the transfer of animals to other technological groups and assessment of the overall physiological state of the herd. (Materials and methods) Expert groups were formed to assess the fatness score at the place of data collection, which consisted of at least two independent veterinarians, two specialists with specialized education. Full-scale data was collected from August 2020 to November 2022 on three farms, the total data set contained 486 images from 182 animals with fatness scores from 1 to 5 (according to the expert group). (Results and discussion) We have developed a methodology for determining the fatness score, which focuses on obtaining the linear dimensions of 5 areas of the back: maklaki, hungry fossa, cruciate ligament, convexity of spinous and transverse vertebrae. It was shown that the mathematical model uses linear regression to evaluate areas of interest. The evaluation methodology was upgraded by an expert group for the possibility of application by a machine vision system. (Conclusions) Developed a system for assessing the fatness of dairy cows, applicable to the operation of a machine vision system; a method for determining the fatness score in increments of 0.25 points on a 5-point scale; a methodology for conducting research and collecting field data; for two years, a data array was collected that contains 486 images from 182 animals with fatness scores from 1 to 5 in increments of 0.25 points (17 classes). The algorithm of automatic assessment of fatness of animals with the subsequent determination of their physiological state was given.
Which scientist are you? Creating self-outgroup overlap with a scientist through a personality matching game
Authors: Beauchamp Alexandra L. , Roberts Su-Jen , Piper Craig
Published: December 2023

Based in intergroup contact theory, we investigated how messaging about shared characteristics affects perceived closeness with scientists (i.e., self-outgroup overlap). In an online study, participants ($N=486$) played a personality matching game that matched them with a real scientist, then they responded to a survey. We replicated the study at a zoo ($N=63$) to examine implementation as a facilitated game. Self-scientist overlap improved in the online setting; in the in situ setting, trust increased, but not self-scientist overlap. Findings suggest that learning about how one scientist is similar to one's self can increase perceived closeness to scientists overall.
Влияние состояния конструкции пути на вибрационное воздействие от трамваев
Authors: Смирнов Владимир , Чечулина Любовь
Published: December 2023

Воздействия, вызванные движением трамваев, часто приводят к возникновению в помещениях близлежащих зданий повышенной вибрации и структурного шума, которые зачастую превышают нормируемые санитарными требованиями уровни, установленные федеральными законами. На величину таких воздействий оказывают влияние как характеристики самого подвижного состава трамваев (скорость, осевая нагрузка, состояние поверхностей катания), так и техническое состояние конструкции верхнего строения пути. Причём последнее в соответствии с положениями СП 441.1325800.2019 может оказать существенное влияние – общее увеличение вибрационного воздействия составляет до 10 дБ для изношенной конструкции пути. В статье проведено сравнение измеренных в натурных условиях характеристик вибрационного воздействия от движения поездов трамвая на одних и тех же участках пути – прямом и криволинейном – до и после их реконструкции. Как показывают результаты сравнительного анализа, реконструкция пути в рассматриваемом случае привела к изменению параметров вибрационного фона, вызванного прохождением поездов трамвая.
«Искусственный интеллект», или «логические рассуждения и разумные решения» в технической диагностике объектов строительства
Authors: Кашеварова Галина
Published: December 2023

Цель данной работы – показать возможности и перспективы применения интеллектуальных технологий именно в строительстве. В настоящее время для этого наиболее широко используются технология экспертных систем (ЭС), теория нечётких множеств и нечёткой логики и искусственные нейронные сети. Системы искусственного интеллекта дают возможность моделировать накопленные профессиональные знания опытных специалистов, опираясь на современные методы решения практических задач, используя существующее нормативное обеспечение строительной отрасли как готовую системную модель, которую следует адекватно представить в терминах, формализованных в соответствии с определёнными структурными правилами. Компьютер позволяет эксперту автономно использовать это, предлагая возможные варианты на основе логического вывода для решения конкретных задач. Реализована возможность выявлять и контролировать автоматизированным способом причинно-следственную связь между признаками и состоянием конструкций, обеспечивающую поддержу решения инженера-обследователя в вопросе определения категории технического состояния конструкций. Неотъемлемой частью диагностики строительных объектов являются поверочные расчёты несущей способности элементов с учётом их реального состояния. Для расчётов сложных строительных объектов обычно используется численный метод конечных элементов. Учитывая то, что искусственные нейронные сети являются хорошими аппроксиматорами различных нелинейных зависимостей, их сегодня предлагается трактовать как новый универсальный подход к численному решению задач математической физики.
Наука в пространстве Санкт-Петербурга: становление
Authors: Фрезинская Наталия , Сергеев Кирилл
Published: December 2023

Статья посвящена проблемам пространственной организации науки в Санкт-Петербурге XVIII века. Отмечаются особенности ситуации, которая возникает, когда возраст столичного научного центра почти не отстаёт от возраста столицы. Характеризуются важнейшие объекты науки и в их числе – Академия наук и художеств. Становление сети этих объектов рассматривается на фоне развития планировочной структуры города. Отмечено влияние технологии производственных процессов на выбор площадок, пригодных для выполнения исследований.

Градостроительному комплексу, возникшему на базе Академии наук и художеств, уделяется особое внимание. На основании сохранившихся документов реконструируется схема расселения её сотрудников на территории Васильевского острова. Отмечается недостаток денежных средств, необходимых для нового строительства – им объяснялась практика покупки для нужд Академии уже построенных зданий или найма квартир. Подчёркивается постепенное преодоление возникавших труд-ностей, сопутствовавшее успехам исследовательской деятельности: для науки в городе началось строительство новых зданий, в проектировании которых учёные принимали активное участие.

Data on prominent representatives of the Muslim elite of the Khorezm khanate of the 19th century, stored in the photo collection of the Khiva State Museum-Reserve “Ichan-Kala”
Authors:   Khorezm Mamun Academy of the Uzbekistan Academy of Sciences, Babadzhanov Dilmurod K.
Published: December 2023

The work reveals the history of the personalities captured in the photograph which is stored in the collections of the Khiva State Museum-Reserve “Ichan-Kala”. At its center is Muhammad Rahim Khan II, the ruler of the Khiva Khanate. Based on historical sources, the author of the article highlights the life and activities of Mukhammad Rakhim Khan II and the palace officials who ruled the Khanate at the end of the 19th century. It is shown that Mukhammad Rakhim Khan II aspired to be the patron of Sharia. He was an enlightened ruler – he supported musical and poetic arts, had polemical conversations with intellectuals, and was fond of writing poems. In 1874, under the patronage of Mukhammad Rakhim Khan II, the first printing house in Central Asia for printing lithographic books was organized in Khorezm. One of the first books published in it were “Khamsa” by Alisher Navoi and “Divan” by the poet Munis.
Private life of a Tatar woman of the pre-reform era (on the example of the Menzelinsk Uyezd)
Authors:   Marjani Institute of History of the Tatarstan Academy of Sciences, Gabdrafikova Liliya R. ,   Federal Research Center “Kazan Scientific Center of the Russian Academy of Sciences”
Published: December 2023

The article restores the social and economic status of Tatar women based on documents of Orenburg Mokhammedan Religious Assembly (OMRS), state audit documents, acts of civil status, and journalistic materials of the 19th-early 20th centuries. The Menzelinsk Uyezd had class specifics and was a part of the military (canton) administration. The chronology of the article starts from the late 18th century and continues until the mid–1860s, due to the fact that at the time the state authorities approved certain laws on marriage and family life of Muslims of the Russian Empire: they changed the age of marriage and legalised inter-class marriages, the OMRS began to regulate marital disputes and inheritance cases. The author places the main focus on the marriage and family aspect of private life and includes many archival examples related to the Tatar women of the Menzelinsk Uyezd. Tatar women turned to OMRS when they needed a divorce or permission to remarry, etc. Women were independent subjects of Muslim and civil law, but they always acted with the support of their relatives. Images of Tatar women in the first half of the 19th century presented in publicistic works are a bit static. Russian authors described only the look of a Tatar woman, the cost of her clothes, accessories, etc. The Tatar view was focused on the composition of the woman’s family (to whom she was married, how many children she had). The article presents the biographies of three Tatar women from the Menzelinsy Uyezd: Kurypla Imanaeva, Gulbadar Akhtyamova, and Khasiba Arduanova. Each case illustrates the main trends in everyday life in the first half of the 19th century (military service problems, the cholera epidemic, etc.). The everyday objects played an important role in interpersonal relations and conflicts. At the same time, in the second half of the 19th century, the Tatar society had an ideal of not only a hard-working and religious woman, but also an educated woman.

A Review of Psychology in the Astronomical Thought of Shaykh Abdullah Fahim
Authors: Zainal Badri Khairul Nizam Bin
Published: December 2023

Astronomy is a very important field because its use covers the entire daily activities of human beings. With the knowledge of astronomy, humans can plan activities well. This study seeks to examine the philosophy of astronomy in the thought of Shaykh Abdullah Fahim (1869 - 1961 AD), a prominent scholar of Penang and its impact on life. Shaykh Abdullah Fahim received his education in astronomy and other religious sciences in Makkah and Madinah. He also took the Naqsyabandiyyah tariqat from his teacher Sayyid Muhammad Amin bin Ahmad Al-Madani. In terms of his educational background, it is almost the same as the Indonesian Minangkabau scholar, Shaykh Muhammad Jamil Jambek bin Saleh Datuak Maleka (1862 - 1947) who has skills in astronomy, and a practitioner of the Naqsyabandiyyah tariqah. On the other hand, this study seeks to look at the significance of this field of astronomy to human psychology according to his point of view. This qualitative -based study uses a fully library approach to gather as much information about Shaykh Abdullah Fahim especially in the field of astronomy. Cross reference is made to the figures of the contemporary Malay scholars to obtain further information about the figures involved in teaching astronomy. In the context of psychology, the field of astronomy is not only able to trigger a high level of thinking but at the same time able to provide motivation and inspiration to humans to start an activity in daily life.

Published: December 2023

Since human being landed on earth, force and violence were used as a tool to ensure individuals survival. It has become the right in system of war to empower protection for the benefit of the aggressed state upon its quest to repel the attack from the other state. The legality of using force and initiating war is basically scaled according to the degree of the self-defense right. In addition, there are cases and situations where strict application of the criteria for the right to the war could lead to the impossibility of achieving the aims and purposes of the war’s law. In such cases, need to be considered in the international law to test it proportionally under the law of war as a part in testing the suitability in order to wage war. The absence of effective international law that govern the use of force and initiating wars. While the provision of the Islamic law and its principles of tolerance has provided detailed controls that deal with war since several centuries. The basic upon which Islam rely is peace between people rather than war.

Published: December 2023

The success criteria of any program, largely revolves around the success of its graduate in the practical field. The teaching practicum gives such opportunities for the prospective teachers to acquire desired teaching skills for a successful -career. The purpose of this study was to explore the experiences of the prospective teachers during teaching practicum by highlighting the opportunities and challenges. As private schools have been recently added to the pool of schools for practicum, therefore the study was delimited to the practicum in private schools that takes place during the third year of their program. Data was collected from 15 prospective teachers of three batches with help of semi-structured interviews. The data analysis was done through initial coding and then classifying codes into four themes.  The emerging themes revealed opportunities in organized environments, infrastructure with facilities, and rigorous learning. Whereas the obstacles included allocation of classes, work pressure and trust concerns of cooperative teachers.  However, the challenges didn’t shadow the learning of prospective teachers and served as much needed experience needed to be successful in future. This research aims to assist teacher educators and policymakers in harnessing the full potential of teaching practicum to cultivate a skilled workforce, ultimately enhancing the quality of education.

Authors: Vasileva Viliana , Georgiev Georgi , Popovic Vera
Published: December 2023

Soybean [Glycine max (L.) Merr.] is a legume and the second most planted crop
after maize in worldwide. The objective of this study was to evaluate the
change in the total plastid pigments content in three soybean varieties
depending on the date of sowing and the row spacing was studied during four
consecutive years (2018-2021). The Avigea, Isidor and Richi varieties, sown
on three dates (I - 28 March - 05 April; II - 19-24 April; III - 09-14 May)
at row spacing of 25, 45 and 70 cm were studied in field conditions. The
plastid pigments (chlorophyll a, chlorophyll b, carotenoids) was determined
in fresh plant samples in the beginning of pod formation stage. The total
content of plastid pigments and the chlorophyll a/chlorophyll b and
chlorophyll a + chlorophyll b/carotenoids ratios were calculated. The total
plastid pigments content varied by years and varieties depending on the date
of sowing and row spacing. The date of sowing was found as a factor with
stronger effect on the plastid pigments content compared to the row spacing.
On average for the period it was found that the total plastid pigments
content in the Avigea variety decreased compared to the first date of sowing
at all three row spacing, most pronounced at 45 cm. The reduction reached
25.59% on the second date and up to 19.02% on the third sowing date. The
strongest effect of the date of sowing on the plastid pigments content was
found in the Richi variety on the third date of sowing, where the increase
was up to 64.33% at a row spacing of 25 cm and up to 36.02% at a row spacing
of 70 cm compared to the first date. The row spacing factor had a smaller
effect - for Avigea variety a decrease of 12.31% was reported on the second
sowing date and a row spacing of 45 cm compared to the 70 cm accepted row
spacing and for Richi variety by 15.79% on the first date and row spacing 45
cm. The chlorophyll a/chlorophyll b ratio decreased at a row spacing of 25
at the second (for Isidor and Richi) and third sowing dates (for Avigea and
Isidor).

El papel de la visualización en el proceso de enseñanza y aprendizaje del Análisis Matemático
Authors: Badía Albanés Valentina , Balbuena Cruz David
Published: December 2023

En las disciplinas que operan con objetos abstractos la visualización de conceptos puede contribuir a una mejor comprensión de los contenidos, a la fijación de formas y métodos de trabajo e incluso a la determinación de vías de solución de los problemas. Dentro de las asignaturas de la disciplina Análisis Matemático, nos encontramos a menudo con la necesidad de apelar a la visualización y a transitar entre diferentes formas de representación de los objetos y contenidos matemáticos. En el presente trabajo se comparten y sistematizan algunas ideas esenciales relativas a la visualización, el pensamiento visual  y su papel dentro de la enseñanza y aprendizaje de esta rama de la Matemática. Además se ejemplifican algunas visualizaciones que se han empleado en los cursos de Análisis Matemático de las carreras de Licenciatura en Matemática y Licenciatura en Física de la Universidad de La Habana.

Authors: Pechetov A. A. , Danilov I. I. , Vishnevskaya G. A.
Published: December 2023

Introduction. Idiopathic cicatricial tracheal stenosis (ICTS) comprises a rare and dangerous disease of unknown etiology. Its morphological substrate consists in the formation of circular fibrotic stenosis, usually at the level of the cricoid cartilage and the first two С-shaped rings of the trachea. The first cases of the disease were described by Brandenburg only in 1972. Progression of the disease is slow, right up to severe respiratory failure and asphyxia. Treatment methods for idiopathic cicatricial tracheal stenosis include both endoscopic and open surgical techniques. However, endoscopic treatment fails to produce the desired effect. Materials and methods. The authors of the present paper performed tracheo-laryngeal resection as a radical method for treating idiopathic tracheal stenosis in a 54-year-old patient against the background of prolonged unsuccessful endoscopic treatment. The follow-up period accounted for 45 days. Examinations in the postoperative period showed complete epithelialization of the anastomosis line without inflammation. Results and discussion. Idiopathic cicatricial tracheal stenosis is considered to be a dangerous disease without significant causes of development. However, it is claimed to be a potentially curable disease, though its treatment is a difficult task. Some authors report satisfactory results of endoscopic treatment of ICTS, but most publications on this issue consider a single tracheo-laryngeal resection with anastomosis as the most optimal method of treatment, thereby correlating with the results of the present study. Conclusion. The present observation characterizes the peculiarity and possibility of radical treatment of ICTS, since the endoscopic method of treatment produces only a temporary effect. Small number of observations and lack of a coherent pathogenetic theory necessitate further research into this problem.

Batik TV Pekalongan City as a government agency provides opportunities for students and college students to do internships. Batik TV does not yet have an internship information system so that internship management is still manual and not computerized. This makes it less efficient and time-consuming because interns must meet the supervisor every day to report daily activities. The purpose of this research is to create an Information System for Managing Internship Activities at Batik TV Pekalongan to make it easier to manage internship activities. This system uses a prototype development method including listen to customer, build/revise mock up, customer test drives mock up. The result of this research is the establishment of an Internship Management Information System that makes it easier for interns to write daily internship activities, makes it easier for supervisors to check daily activity reports, and makes it easier for admins to manage internship data.

Published: December 2023

Rubber has been widely employed in the automotive industries in various components. One component that benefits rubber is the braking system which is essentially for stopping the vehicles safely. This investigation intends to characterize the rubber degradation by applying pre-determined cyclic loadings; 10,000, 100,000, and 500,000 cycles which implicated the deformation of this rubber in the brake wheel cylinder while in service. The residual compression properties of rubbers were determined by using a uniaxial compression test. The damage development in rubbers was characterized using X-ray crystallography (XRD), pyrolysis gas chromatography-mass Spectrometry (GC-MS), and scanning electron microscope (SEM). The result indicates the rubber degradation is clearly visualized in the compression test for which lower stiffness is associated with higher cycle specimens. There is evidence of microcracks formation in SEM images which indicates the softening effect of the 100,000 cycles sample. There is a positive correlation between the number of cycles and the peak height intensity in the programs of GC-MS. In addition, the XRD results indicate evidence of crystallization reduction on the damaged samples as samples degrade under cyclic loading.

STRENGTHENING RELATIONS AMONG IDEOLOGIES IN THE MIDST OF RELIGIOUS MOVEMENT CONFLICT IN GLADAK PAKEM JEMBER
Authors: Mahillah  , Muhammad Faiz
Published: December 2023

In a multicultural and diverse country like Indonesia, relations between religious movements sometimes encounter friction and conflict. This study will highlight the Imam Syafi'i Dirosat Islamiyah High School movement (STDI Imam Syafi'i) which has been established since 2007 with the initial name Ma'had Aly Imam Syafi'i. This Islamic educational institution is one of the Wahhabi ideology institutions in Jember Regency. According to the Wahhabis, Muslims are obliged to return to Islam, which is seen as pure, simple, and righteous, which is believed to be fully reclaimed by strictly carrying out the commands and example of the Prophet and strictly following correct ritual practices. These groups made the majority of the Jember community such as Nahdlatul Ulama (NU) followers feel uneasy about the existence of the STDI Imam Syafi'i campus with Wahhabi ideology. NU community feels that their existence is threatened as the majority group in Jember. Ideologically and religiously, Wahhabis and NU are very different. Many Nahdliyyin practices are considered heretical (bid'ah) by the Wahhabi group. Meanwhile, according to the community around the Imam Syafi'i STDI campus, it is different. The existence of the STDI campus provides a better economic impact for members around the campus. Since the campus has been operating, members' income has increased by opening food stalls, rented houses, and student boarding houses. The conflict started from differences in understanding in capturing religious arguments sourced from the Quran and Sunnah. The existence of interpretations, thoughts, and opinions of scholars (ijtihad) has triggered the understanding of Muslims. The attitude of NU members who are members of the TOPI Bangsa action in Jember shows the potential for conflict that can happen at any time. Considering that neither the security forces nor the local government have proven strong enough to anticipate open conflicts behind conflicting beliefs.
