The article examines the processes of reindustrialization of the national economy in the subjects of the federation. At the same time, special attention is paid to the problem of providing reanimated industries with qualified workers. Using the example of the Chuvash Republic, the analysis of the general state of the regional economic complex, the system of secondary vocational education (SPE), as well as the main demographic indicators is carried out. The authors investigated the dynamics of the number of young people aged 15-18 years as potential recipients of SPO. As a result, a polynomial trend equation of the 2nd order is obtained, which makes it possible to predict the value of the indicator on the prediction horizon up to 8 years. It is shown that in the medium term, a full-fledged contingent of students in the regional vocational education system can be formed even in an unfavorable demographic situation.

Emotional intelligence gained worldwide attention as it got revealed that having good Emotional Intelligence (EI) is more important than that of IQ. It becomes even more important to study about emotional intelligence among students as they are the building blocks of the future (Goleman D, 1995). Integrating EI equips students with the tools to manage interpersonal relationships, build resilience, and adapt to the complexities of the modern world. Furthermore, the integration of emotional intelligence into school curriculum fosters a culture of inclusivity and understanding. The effects of high and low emotional intelligence are tried to study in here, how the emotional intelligence effect the overall growth of the student in all fields. It is found that the emotional intelligence of the students have a strong connection to their overall development and growth academic wise as well as career wise. Traditional education has long focused on the development of cognitive and academic skills, often overlooking the importance of emotional intelligence. However, recent research suggests that EQ plays a significant role in a person’s overall well-being, happiness, and success. By incorporating emotional intelligence education into the curriculum, schools can equip students with essential life skills that foster resilience, empathy, effective communication, and emotional well-being, preparing them for the challenges they will encounter in their personal, academic, and professional lives.

Abstract
Al-Jabal Al-Akhdar in northeastern Libya is renowned for its distinctive Mediterranean mountain ecosystems, high biodiversity, and a significant proportion of endemic plant species. Yet, limited comprehensive ecological studies have focused on its wadi systems, particularly in the face of increasing anthropogenic pressures. This study examines the vegetation of Wadi Om-El-Amaym, a northern segment of Wadi Al-Agar, with the aim of assessing species composition, taxonomic diversity, life-form distribution, and the impact of human activities on local flora. Field surveys were conducted over a 12-month period, during which plant specimens were collected, identified, and categorized into major taxonomic groups and life forms using standard floristic and ecological methodologies. A total of 141 species spanning 43 families were recorded, including nine endemics and several taxa with medicinal properties. Dominant families included Fabaceae, Poaceae, and Geraniaceae, while Trifolium and Erodium emerged as particularly species-rich genera. Analysis of life-form spectra revealed a prevalence of annual therophytes, alongside the presence of woody phanerophytes and chamaephytes, reflecting adaptations to the region’s varied topography and climatic conditions. However, the vegetation is increasingly threatened by overgrazing, woodcutting, agricultural expansion, and other human-driven disturbances. These pressures have led to habitat degradation, putting several species at risk. The findings highlight the urgent need for targeted conservation measures, sustainable land-use practices, and increased environmental awareness to preserve the ecological integrity and unique botanical heritage of Wadi Om-El-Amaym and the broader Al-Jabal Al-Akhdar region.

Published: December 2024

Anti-thymocyte globulin related anaphylaxis is rare but life-threatening. Thymoglobulin is a purified, pasteurized, rabbit-derived T-cell depleting polyclonal gamma immunoglobulin, obtained by immunization of rabbits with human thymocytes, commonly used for treatment of acute rejection in renal transplantation and induction immunosuppression. We report a case of a cadaveric renal transplant recipient who developed intraoperative anaphylactic shock, likely triggered by thymoglobulin administration. This case report signifies the importance of prompt diagnosis and management of intraoperative anaphylaxis, as early intervention is crucial for achieving a successful outcome. Communication between the anaesthesia team, nephrologists and surgeons played a key role in taking the decision of continuing the transplant.

Published: December 2024

Работа посвящена совершенствованию методов оценки волновых нагрузок на корпус судна с расширением возможности учета нелинейных эффектов: изменяемая смоченная поверхность, слеминг, заливаемость палубы, деформируемость корпуса. Разработаны численные модели повышенной эффективности, которые относятся к моделям пониженного порядка. В качестве основного инструмента приняты проблемно-ориентированные нейронные сети, формирующие нейронную систему линейных дифференциальных уравнений в пространстве внутренних переменных. Параметры такой системы подбираются из условия адекватного моделирования нелинейного поведения исходной системы. Эталонное решение получено с помощью разработанного решателя во временной области на основе одномерной модели деформируемого корпуса, плавающего на взволнованной поверхности воды с допущениями плоской модели обтекания сечений. В результате проведенных расчетов представлены данные о параметрах волновых нагрузок на контейнеровоз, демонстрирующие высокую степень согласия между результатами численного моделирования и прогнозами модели пониженного порядка. Предложенный в работе математический аппарат имеют потенциал для дальнейшего применения в практике судостроения, позволяя более точно прогнозировать поведение судов в условиях волнения.

The work is devoted to improving methods for estimating wave loads on the hull of a vessel with the expansion of the possibility of taking into account nonlinear effects: variable wetted surface, slamming, green water, hull deformability. Numerical models of increased efficiency have been developed, which relate to models of reduced order. Problem-oriented neural networks forming a neural system of linear differential equations in the space of internal variables have been adopted as the main tool. The parameters of such a system are selected from the condition of adequate modeling of the nonlinear behavior of the initial system. The reference solution was obtained using the developed time domain solver based on a one-dimensional model of a deformable hull floating on an agitated surface of water with the assumptions of a flat flow model of sections. As a result of the calculations, data on the parameters of the wave loads on the container ship are presented, demonstrating a high degree of agreement between the results of numerical modeling and the forecasts of the reduced-order model. The mathematical apparatus proposed in the work has the potential for further application in shipbuilding practice, allowing for more accurate prediction of the behavior of ships in conditions of wave sea.

Published: December 2024

В статье рассматривается задача построения системы идентификации возмущающих воздействий в электроприводах робототехнических комплексов. Для её решения используется подход, основанный на использовании оптимальных астатических наблюдателей. Это позволяет избежать недостатков других методов идентификации, таких как необходимость высокочастотной коммутации скользящих наблюдателей. Оптимальные наблюдатели предлагается строить на основе редуцированных моделей исходной диагностируемой системы, получаемых с помощью специально разработанного алгоритма и имеющих меньшую размерность, по сравнению с исходной моделью системы. Это упрощает дальнейшую реализацию оптимальных наблюдателей. Используя предлагаемую процедуру синтеза наблюдателя, также удается придать ему свойство астатизма и исключить статическую погрешность определения величины возмущения. Работоспособность и эффективность предложенной системы идентификации подтверждена компьютерным моделированием.

The article considers the problem of constructing a system for identifying disturbing influences in electric drives of robotic complexes. To solve it, an approach based on the use of optimal astatic observers is used. This avoids the disadvantages of other identification methods, such as the need for high-frequency switching of sliding observers. Optimal observers are proposed to be built on the basis of reduced models of the initial system being diagnosed, obtained using a specially developed algorithm and having a smaller dimension compared to the initial system model. This simplifies the further implementation of optimal observers. Using the proposed procedure for synthesizing an observer, it is also possible to give it the property of astatism and eliminate the static error in determining the magnitude of the disturbance. The efficiency and effectiveness of the proposed identification system has been confirmed by computer simulation.

The article proposes a method for synthesizing a system of AUV trajectory control considering the uncertainty of the AUV parameters, as well as the limitations of the values of the control thrusts and torques formed by its propulsion complex. To solve this problem, a robust spatial position control system is synthesized, which considers the influence of interactions between the degrees of freedom of the AUV and the uncertainty of their parameters. At the same time, to ensure the accurate movement of the AUV during the mission, an additional control loop for correcting the program speed of movement is synthesized. This loop to consider the possible entry of the AUV thrusters into saturation and its departure from the trajectory. The main feature of the proposed method of correction of the program speed is to consider the peculiarities of the AUV dynamics and the kinematics of its propulsion system, which allows you to quickly adjust the program speed of movement without waiting for the thrusters to enter the saturations.

Published: December 2024

В настоящее время существует тенденция к расширению области применения автономных необитаемых подводных аппаратов, в частности актуальной является задача автоматического выполнения технологических операций с помощью многозвенных подводных манипуляторов. В статье рассматривается проблема построения адаптивных систем управления электроприводами подводных манипуляторов, использующих только информацию о положении выходных валов этих приводов. Для реализации такой системы сначала строится преобразованная модель электропривода манипулятора, чувствительная к возникновению ненулевого внешнего момента, но у которой в отличии от исходной модели могут быть определены все фазовые координаты. Далее, на основе этой модели синтезируются диагностические наблюдатели, позволяющие в режиме реального времени оценивать внешний крутящий момент, приводимый к выходному валу соответствующего электропривода, а также угловые скорость и ускорение его вращения. Эти оценки затем используются для реализации самонастраивающихся корректирующих устройств, стабилизирующих переменные параметры электроприводов на некотором номинальном уровне за счет подачи дополнительного управляющего воздействия. Эффективность такой системы была подтверждена с помощью математического моделирования автономного необитаемого подводного аппарата с манипулятором.

Currently, there is a tendency to expand the scope of autonomous underwater vehicles. In particular, the task of automatically performing technological operations using multi-link underwater manipulators is urgent. The article deals with the problem of building adaptive control systems for electric drives of underwater manipulators using only information about the position of the output shafts of these drives. To implement such a system, a transformed model of the manipulator electric drive is first constructed, which is sensitive to the occurrence of a non-zero external moment. Unlike the original model, all phase coordinates of this model can be determined. Further, diagnostic observers are synthesized using this model that allow real-time evaluation of the external torque acting on the output shaft of the corresponding electric drive, as well as the angular velocity and acceleration of its rotation. These estimates are then used to implement self-adjusting corrective devices that stabilize the variable parameters of electric drives at some nominal level by providing additional control signal. The effectiveness of such a system was confirmed using mathematical modeling of an autonomous underwater vehicle with a manipulator.

The paper proposes an option for constructing a system for coordinated control of the position of interconnected electric drives of a multi-purpose robotic transport platform for carrying out work on laying and comprehensive maintenance of main pipelines. A feature of the control object under consideration is the implementation of a positioning system based on a number of functionally connected electric drive units. For the proposed robotic transport platform, an analysis of possible options for implementing positioning units was carried out. Based on the structure of the positioning units, a relationship was derived between electric drives of the motor-wheel type, ensuring the movement of the proposed complex through the pipeline. Dependency describes the mutual influence of moments developed in the process of work. Taking into account the obtained functional dependence, the calculation of the regulators of the averaged and relative motion in the position loop was carried out and a simulation model of a coordinated control system for electric drives of the motor-wheel type was implemented and studies of the system’s operation were carried out.

В статье рассматривается задача динамического позиционирования автономных подводных необитаемых аппаратов с системой управления. Используется архитектура визуального управления на основе изображения для динамического позиционирования оснащённого монокулярной видеокамерой. Подход визуального управления на основе изображения использует координаты объекта в плоскости изображения в качестве обратной связи и, таким образом, по своей сути устойчив к ошибкам в калибровке камеры и модели объекта. Одна из основных трудностей при реализации системы управления на основе изображения для подводных аппаратов возникает из-за неопределенностей, связанных как с матрицей Якобиана изображения, так и с динамикой объекта. Задача динамического позиционирования рассматривается для автономного необитаемого подводного аппарата, движущего в горизонтальной плоскости при действии возмущающего воздействия. Управление осуществляется с помощью продольной линейной скорости и угловой скорости рыскания, основанных на данных, получаемых от монокулярной видеокамеры о положении центроида найденного на объекте или центроида выбранных ключевых точек дна, с использованием подхода IBVS. Полученные результаты проиллюстрированы компьютерным моделированием.

An image-based visual control approach uses the object coordinates in the image plane as feedback and is thus inherently resistant to errors in camera and object model calibration. One of the main difficulties in implementing an image-based control system for underwater vehicles arises from the uncertainties associated with both the Jacobian matrix of the image and the dynamics of the object. The problem of dynamic positioning is considered for an autonomous underwater vehicle moving in the horizontal plane under the action of a disturbing influence. It is controlled using longitudinal linear velocity and yaw angular velocity based on data obtained from a monocular video camera on the position of the centroid found on the object or the centroid of selected key bottom points, using the IBVS approach. The obtained results are illustrated by computer modeling.
Primary Malignant Peritoneal Mesothelioma Mimicking Ovarian Carcinoma: A Case Report Highlighting the Importance of Immunohistochemistry

Published: December 2024

Background: Primary malignant peritoneal mesothelioma (PMPM) is an uncommon and aggressive malignancy arising from the mesothelial lining of the peritoneal cavity. The diagnosis of PMPM is often challenging due to its rarity, nonspecific clinical presentation, and histologic similarities to other malignancies, particularly adenocarcinomas. Immunohistochemistry plays a crucial role in differentiating PMPM from metastatic adenocarcinoma, which is essential for accurate diagnosis, appropriate treatment, and prognostication.
Case presentation: We present the case of a 43-year-old female who presented with abdominal distension, ascites, and weight loss, initially raising suspicion of ovarian carcinoma. However, histopathological examination of the omental tissue revealed a proliferation of epithelial cells with papillary and glandular-like growth patterns. Immunohistochemical staining demonstrated strong positivity for calretinin, a mesothelial marker, while staining for estrogen receptor (ER) and progesterone receptor (PR) was negative, effectively ruling out an ovarian or endometrial origin. The diagnosis of PMPM, epithelioid subtype, was confirmed.
Conclusion: This case underscores the challenges in diagnosing PMPM and highlights the critical role of immunohistochemistry in differentiating it from metastatic adenocarcinoma. Accurate diagnosis is essential for determining appropriate management strategies and providing prognostic information.
„Nerunā sliktu par Latviju”: Latvijas, latviešu un latviešu valodas atainojums digitālajos valsts valodas mācību līdzekļos

Language teaching aids are unique reference materials that both strengthen students’ language knowledge and skills and offer them to discuss linguistic and social topics, showing the consistence and variability of language structure and use in different cultural-historical and socio-political settings. One of the most important contexts for understanding such topics and subjects is the country where the target language is legally defined, used, and discussed. The representation of the country plays an essential role in the teaching materials of the first and second language because they help students form their national identity and encourage them to feel national pride and patriotism.
During the project “Competence approach to learning content” implemented by the State Education Centre (2016–2023), national standards of the Latvian language subjects, sample programs, methodological support materials, and teaching aids have been developed and approved by language education policy makers, linguists, and language teachers. They show involved participants’ understanding about learning content and effective methodology appropriate for today’s youth. The image of Latvia, Latvians, and the Latvian language constitutes this view withih the learning materials.
The goal of the article is to identify and discuss typical national narratives about Latvia, Latvians, and the Latvian language in digital teaching aids of the state language, paying special attention to diversity as a feature of the country, its inhabitants, and the language situation. To achieve the goal, the theory of inclusive nationalism (Tamir 2019) has been used and content analysis of 215 Latvian language teaching aids published in the digital learning resource repository “Mape” has been carried out according to Risager’s model for language teaching aid analysis (Risager 2018).
During the research, four main national narratives were formulated:
1. Latvia is a small country on the world scene, but a vast land for its inhabitants.
2. The creation, existence, and international recognition of Latvia as a nation is impossible without outstanding Latvians.
3. The Latvian language is the core concept of national identity and a component of the world’s linguistic diversity that must be preserved.
4. Latvia is an ethnically and linguistically homogeneous country where everyone speaks Latvian in their own way and learns other languages.
In sum, the ideas of inclusive nationalism are in the language education policy – in the Latvian language subject standards and sample programs (formally), but in practice – in the language teaching materials – they are not implemented. The concept of Latvian-ness is not extended to the identities, knowledge, experiences, traditions, and daily practices of all Latvian residents.

Parodies of Imperial Discourse in Sixth-Century AD Greek Epigrams
Authors: Febrer Oriol
Published: December 2024

Sixth-century Greek book epigrams can offer insights into debates and ideas present in their historical context, also into the shaping of a Christian polity. Through a case study of two epigrams, this article explores how these pointed and playful compositions parody and subvert imperial discourse thanks to intertextual allusions to Justinian’s legislation, chiefly his Novellae. The first epigram (AP XI.238) is an example of criticism on administrative decisions, namely the appointment of an official, probably John the Cappadocian, by the emperor. The second epigram (AP V.302) shows farther-reaching criticism on Justinian’s legal and moral reforms regarding marriage and sexual behaviour; it emphasises that sexual gratification is not possible anymore in the society reshaped by the emperor.
