Analytic First-Order Derivatives of CASPT2 Combined with the Polarizable Continuum Model
Authors: Nishimoto Yoshio
Published: October 2024

The complete active space second-order perturbation theory (CASPT2) is valuable for accurately predicting electronic structures and transition energies. However, optimizing molecular geometries in the solution phase has proven challenging. In this study, we develop analytic first-order derivatives of CASPT2 using an implicit solvation model, specifically the polarizable continuum model (PCM), within the open-source package OpenMolcas. Analytic gradients and non-adiabatic coupling vectors are computed by solving a modified Z-vector equation. Comparisons with existing theoretical and experimental results demonstrate that the solvent effects can be qualitatively captured using the developed method.
Controlled Chain-Growth Polymerization via Propargyl/Allenyl Palladium Intermediates
Authors: Wang Zheng-Lin , Zhu Rong
Published: October 2024

In contrast to allyl palladium complexes, propargylic/allenylic palladium speicies display complex reactivities that limit their implementation in polymer chemistry, especially for chain-growth polymerizations. Here we report the the first example of controlled chain-growth polymerization via propargyl/allenyl palladium intermediates. Vinylidenecyclopropane 1,1-dicarboxylate (VDCP), a unique allenylic electrophile, selectively reacts via the sigma-allenyl palladium complex rather than the more common pi-propargyl pathway, thereby unlocking a chain-growth process. Based on this concept, precise synthesis of alkyne-backbone polymers is realized, featuring fast rate, high molecular weight, narrow dispersity, high chemoselectivity, and excellent end-group fidelity. We demonstrate preparation of unsaturated macromolecules with advanced sequences and architectures using this method, including block, gradient, and graft copolymers.

Authors: Herrera Brunal María Camila , Terán Torres Héctor Rafael
Published: October 2024

The field of engineering has traditionally prioritized the development of technical skills and specialized knowledge, often neglecting soft skills, which are also essential for professional success. This lack of soft skills has become evident even in the preparation of students for their professional internships, creating a gap between the job competencies required by the industry and the skills that engineers typically possess upon graduation. In this study, with a qualitative methodological approach, we proposed researching good practices and pedagogical approaches for teaching and developing soft skills in engineering education with students at a Higher Education Institution in the Caribbean Region. Additionally, with the goal of executing a methodology that incorporated specific activities to develop these skills. These activities included interdisciplinary projects, real-case simulations, and counseling sessions to prepare students for their early professional years. Similarly, this methodology required active collaboration and co-creation involving both teachers and students, recognizing their potential to contribute to the development of new educational models that led to evident transformations. These transformations demonstrated significant improvements in communication skills, teamwork, problem-solving, and leadership, aligned with ABET Student Outcomes. The study's results indicate that promoting soft skills as part of the comprehensive training of engineers can heighten students' awareness of their importance in meeting the challenges of today's job market. The students demonstrated significant competence in developing these skills. In conclusion, the development of soft skills within the field of engineering is an essential initiative that must be undertaken during the university years to bridge the gap between academia and industry. If not addressed, this gap will continue to widen, potentially forcing graduates to spend their early professional years acquiring these skills.

Published: October 2024

El municipio de Aguachica es un punto estratégico para la comercialización de productos agrícolas, sin embargo, enfrenta problemas de escasez y mala gestión del agua por parte de las autoridades locales, obligando a sus habitantes a recurrir a fuentes subterráneas contaminadas, lo que aumenta el riesgo de enfermedades. Varias investigaciones realizadas en el municipio han publicado la pésima calidad del agua que tiene la quebrada Buturama, la cual es la principal fuente de abastecimiento de agua potable del casco urbano, debido al uso excesivo de productos agroquímicos para la agricultura en la zona, los que afectan tanto las corrientes superficiales como subterráneas. En las áreas cercanas de la ribera de la quebrada Buturama, los cultivos principales son algodón, sorgo, arroz y maíz, y se emplean técnicas mecanizadas para su cultivo. Sin embargo, debido a la pérdida de nutrientes en el suelo, se requiere una cantidad considerable de fertilizantes para mantener la productividad. Esta práctica agrícola aumenta la vulnerabilidad de los cultivos a plagas y enfermedades, lo que promueve el uso excesivo de agroquímicos, especialmente de herbicidas como el Glifosato que es ampliamente utilizado en la zona debido a su efectividad en el control de malezas. El objetivo principal de esta investigación fue determinar la concentración de Glifosato en tres áreas del Municipio de Aguachica, donde los habitantes dependen de fuentes subterráneas para el suministro de agua, así como en una zona que utiliza agua tratada proveniente de la planta de tratamiento. El herbicida se cuantifico mediante espectrofotometría ultravioleta – visible (UV/VIS), donde dos de los tres puntos de agua subterránea arrojaron concentraciones (0.118 y 0.101 ppm) superiores a los niveles máximos permitidos en la Resolución 2115 del 2007 (0.1 ppm), sin embargo, se debe tener en cuenta que dicha normativa contempla la sumatoria de todos las concentraciones de los productos agroquímicos; así mismo, al comparar los resultados obtenidos con los estándares internaciones, todos los puntos estudiados sobrepasan los límites de países como: Reino Unido (0.0001 ppm) y la unión Europea (0.0001 ppm); y por debajo de Canadá, Australia y Estados Unidos. Por su parte, con la concentración hallada en todos los puntos de muestreo se realizó la evaluación cuantitativa de riesgos para la salud humana, determinando que, según las directrices para la calidad del agua potable de Canadá y para la Organización Mundial de la Salud (OMS) se encontraban en riesgo bajo. Sin embargo, la presencia de este herbicida en las fuentes de agua potable plantea una preocupación continua sobre la salud pública y destaca la necesidad urgente de medidas de control y regulación más estrictas en el uso de agroquímicos en la región.

Authors: Velasco Peña Marco Antonio , Mendez Pedro , Malagón Romero Dionisio Humberto
Published: October 2024

Sugarcane is used as a raw material for the production of energy and food in different regions of Colombia. The main product obtained from cane is sugar, which generates a waste resource: bagasse. In a sugar mill, bagasse is used as fuel in the Rankine cycle for power and steam generation. In this work, based on experimental data from a sugar mill, energy and exergy analyses were performed to establish improvements in this cycle. Based on the analysis of the first and second laws, an analysis is conducted on the change in the conditions of the steam inlet to the turbines to determine the improvement in energy efficiency and the decrease in exergy destruction. The results show that the input conditions of 6.58 MPa and 783.15 K allow the highest power and efficiency of the cycle to be obtained, with a net power of 34274 kW and an energy efficiency of 81.8%. The greatest loss of exergy occurs in the boiler, which represents 53.87% of the bagasse exergy. On the other hand, an exergy yield of 23.14% is obtained. It is expected that new research methodologies will be implemented and that the design of new sugar mills and the optimization and improvement of existing mills will be considered to obtain better performance and reduce atmospheric pollution and energy and economic benefits for the region.
Dimensiones analíticas para el estudio de las representaciones sociales respecto a la Inteligencia Artificial, en entornos educativos de ingeniería
Authors: Castillo Rosas Adriana , Ramírez López Martha , Ledezma Peralta Alejandra Isabel
Published: October 2024

Las Representaciones Sociales se refieren a las ideas, conceptos, juicios y valores compartidos por un grupo de personas, y ayudan a interpretar y dar sentido a una realidad. Es decir que posibilitan el intercambio discursivo; son las formas de conocer y convertir las ideas colectivas en un marco común interpretativo. En ese sentido, los entornos de formación en ingeniería se encuentran definidos por aquellas representaciones sociales que los actores educativos han construido y compartido desde la génesis de la profesión. Dichas representaciones se crean en un contexto determinado y se encuentran en un proceso permanente de construcción, deconstrucción y reconstrucción definido por los elementos que se integran o desaparecen en aquel. Es así como la Inteligencia Artificial Generativa (IA) se presenta como un elemento disruptivo que comienza a formar parte del discurso educativo a través de nuevas representaciones sociales (RS) entre la comunidad académica del Tecnológico Nacional de México. La apropiación significativa de lo que es, lo que implica, lo que abona y lo que impacta la IA determinará las nuevas relaciones formativas, de enseñanza y aprendizaje. El trabajo que se presenta a continuación consiste en el desarrollo teórico-conceptual de las dimensiones analíticas para el estudio de las Representaciones Sociales respecto a la Inteligencia Artificial, en entornos educativos de Ingeniería: tecnológica, actitudinal y formativa. Se trata de un avance del proyecto de investigación desarrollado en el TecNM Campus CIIDET, titulado Representaciones sociales de los profesores respecto a la Inteligencia Artificial, en el entorno educativo de la Educación Superior Tecnológica.

Bandwidth estimation in network probing techniques utilizing min-plus algebraic methods
Authors: Neelam Tiwary , Ignatius Antony Herman , Samson D.
Published: October 2024

Bandwidth estimation in network probing techniques plays a crucial role in modern networks, particularly in ensuring superior Quality of Service (QoS). This is largely influenced by advancements in IEEE 802.11 standards, which aim to enhance service performance. Existing methodologies are designed to assess the available resources on a given channel, providing valuable support for bandwidth-constrained applications. However, these methods encounter limitations due to potential non-linearities within networks. The current approach leverages min-plus algebra from network calculus, which, although effective, falls short in certain dynamic scenarios. In this research, we propose a novel methodology for bandwidth estimation by integrating other state-of-the-art QoS protocols while maintaining the foundational principles of the min-plus algebra technique. This approach aims to develop a more versatile and adaptable system, better suited for complex network environments.

Authors: Abiramee R. , Priyadarshini S. , Krithina P. D. , Jaya Suriya G.
Published: October 2024

Anemia, characterized by low hemoglobin levels, affects a significant portion of the global population, particularly children and women in low- and lower-middle-income countries. Traditional hematological tests for diagnosing anemia can be invasive, costly, and resource-intensive. This study presents the development of a wearable, non-invasive anemia detector utilizing infrared (IR) technology. The device integrates a NodeMCU microcontroller, an OLED display, a buck converter, an IR transmitter, and a receiver in a compact, wearable package. The IR system measures hemoglobin levels by analyzing the absorption of infrared light emitted through the skin, typically on a fingertip or earlobe. The NodeMCU processes the light absorption data using sophisticated algorithms to determine hemoglobin concentration and facilitates wireless data transfer to smartphones or cloud servers for further analysis. The device is designed with energy efficiency in mind, utilizing a buck converter to ensure optimal power distribution to sensitive components. The OLED display provides users with clear, real-time feedback on their hemoglobin levels, offering a user-friendly interface. Initial testing and calibration with known hemoglobin concentrations demonstrated strong correlations between device readings and traditional lab tests. The device employs a hierarchical ensemble classifier to categorize individuals as healthy, mildly anemic, or severely anemic, aligning with clinical standards. The non-invasive nature of this device, combined with its portability and cost-effectiveness, makes it an ideal solution for point-of-care anemia detection, particularly in resource-limited settings. The integration of IR technology, microcontroller processing, and wireless communication presents a practical tool for healthcare providers, facilitating rapid anemia screening and ongoing monitoring. This innovation holds the potential to improve patient outcomes by enabling early detection and intervention in anemia management.

Assessment of the influence of glycol and alcohol on the morphology and protective properties of iron carbonate in carbon dioxide corrosion of gas pipelines
Authors: Vagapov R. K.
Published: October 2024

The potential effect of hydrate formation inhibitors (glycols, alcohols) — components of the liquid phase of gas pipeline operating media — on carbon dioxide corrosion during the transport of aggressive gas has not been sufficiently studied. The paper presents the results of a study of the corrosive effect of glycol (alcohol) present in the liquid phase on the composition and properties of corrosion products on steel when modeling the main aggressive factors under conditions of transport of CO2-containing gas. On a corrosion stand, the aggressive conditions of alternating wetting of gas pipeline walls with water were reproduced. The fluid circulation characteristic of a partially filled pipeline can have an effect on preventing the formation or destruction of films of corrosion products (iron carbonate, siderite) on the steel surface. In places of cracking and peeling of siderite formed in the presence of CO2, conditions will be created for the formation of general and local corrosion damage. During simulation tests, monoethylene glycol and isopropanol, as well as their aqueous solutions of different concentrations, were used. For the first time, data on the formation and composition of non-stoichiometric siderite in water-glycol and water-alcohol media at CO2 partial pressures and temperature were obtained. By processing diffraction patterns obtained by X-ray diffraction, the degree of substitution of iron ions in non-stoichiometric siderites by other cations was determined. The dependence of the degree of substitution on the concentration of alcohol (glycol) in their aqueous solutions was analyzed. It was revealed that with an increase in glycol concentration, a decrease in the rate of local corrosion is observed. With a high glycol content, internal corrosion is completely suppressed in the presence of CO2. It has been established that in aqueous-alcoholic media at elevated temperatures, local carbon dioxide corrosion does not occur. This is apparently due to the uneven distribution of water and alcohol in the mixture. The results obtained can be used in assessing internal carbon dioxide corrosion in the presence of glycol (alcohol), used at gas facilities as an inhibitor of hydrate formation.

In higher education, blended learning technology combining e-learning and classroom activities has become widespread. Blended learning contributes to the introduction of variable forms and ways of interaction between students and teachers, interaction of study process participants with content, and the expansion of the teacher’s toolkit when working with students. In order to identify and justify the pedagogical conditions of effective organization of blended learning in universities, the authors have described the essence and main components of blended learning technology, and the options of its implementation using learning management systems (LMS). LMS can be classified as to types of licensing, a set of functionality, the module-based criterion, the “customer requirement” criterion, and physical location. The articled presents and identifies features and capabilities of one of the most common learning management systems - LMS MOODLE. The authors reveal pedagogical conditions for the successful implementation of blended learning technology at a university: development of a syllabus and training curricula, correlation of the possibilities of their implementation with the use of blended learning technology; competent course design and implementation, as well as active updating of the content of LMS courses to ensure their quality and relevance; providing timely teacher support for communication and feedback with students; development and application of special methods for monitoring and assessing educational results to carry out reliable and valid diagnostics of learning outcomes and provide prompt feedback; development of high-quality methodological support for teachers on the organization and implementation of the educational process in new conditions and produce methodological materials for students; ensuring a high degree of readiness of students and teachers to implement training in a new format, organize their training and support end contribute to the development of digital competences.
Conceptual foundations of the ecosystem of modern pedagogical education
Authors: Leontieva I.
Published: October 2024

The proposed article attempts to systematize the scientific understanding of the development
of education at the present stage, the challenges and risks it faces in a turbulent world. In particular, the author
revisits the legacy of Viktor Ognevyuk, who believed that the civilizational transition from industrial to postindustrial
society led to the evolutionary formation of a new type of person — «Homo educatus» (educated
person). The researcher was convinced that homo educates has a special mission, designed to harmonize his being
and spiritual sphere with the being of the world. Therefore, today, «facing the era of chaos,» when we do not know
the «rules of the game» under which education will meet the requirements of time, the requirements of the BANI
world, we must create an educational model that is able to respond quickly and flexibly adjust in a turbulent world.
This task has led to the need to study different models of higher education development (elitist, egolitarian and
ecolitarian); to characterize the nature and characteristics of ecosystems, their key components and properties.
The study made it possible to identify the conceptual foundations for building an ecosystem of modern teacher
education, its subsystems, principles of interaction and mutual influence. The conceptual basis of the ecosystem
of teacher education, through the prism of which it is possible to outline its contour, is the following theories
systems (four main approaches to understanding the types of objects of teacher education systems), coevolution
(to identify key components (subsystems) and principles of building the interaction of its elements, their
interdependent integration changes), synergy (to achieve a higher total effect in the interdependent interaction
of subsystems) emergence (the ecosystem of teacher education will have special properties that are not
characteristic of its subsystems and blocks, as well as the sum of elements not connected by systemic links)
and holism (the ecosystem of teacher education is considered as an integral indivisible phenomenon, the result
of creative evolution). The study also found that Ukraine is in the process of developing separate educational
ecosystems, which led to the conclusion that scientific research on this issue is relevant for the development of a
holistic ecosystem of national education.
Application of ic technologies (ict) in the context of formation of subject-methodical competence of future primary school teachers

Published: October 2024

The article highlights the problem of using information and communication technologies
for the formation of subject-methodical competence of future primary school teachers. According to the authors,
a competent teacher of the New Ukrainian School must master the skills of searching in the information space,
using and creating electronic resources in the educational process of primary school. Students of pedagogical
specialties need to develop professional skills in methodical modeling using digital technologies. The authors
analyzed the use of digital technologies in classes on professional methods and identified the most effective
programs for the implementation of educational and methodological tasks of ensuring the educational process
in primary school. The article presents students’ work with mind maps, comics, word clouds, infographics, virtual
whiteboards, interactive tasks and online tests. These programs are applied to professional methods as a means
of visualizing and systematizing educational material, as well as for pedagogical modeling of lesson plans.
SCIENTISTS AS A SUBJECT OF THE “SOCIAL CONTRACT” IN THE PRE-WAR PERIOD
Authors:   Russian State University for the Humanities, Vorobyova Irina V.
Published: October 2024

The article deals with the issues of coexistence between the authorities and scientific intellectuals during the period of political, economic and social transformations of the late 1920s – early 1940s. Two time periods are considered – from 1924 to 1932 years and from 1933 to 1941 years. For each of them it describes, firstly, the state’s policy towards scientists, the consequences of the policy for the whole country and certain social group. Secondly, what aspirations, interests, orientations were characteristic of scientists, what they consisted of, how they correlated with state interests, as well as the interests of the whole people
