Published: September 2024

The flow cytometry method is used in many fields, not only scientific, but also clinical. In science, flow cytometry is used in immunology, molecular biology, microbiology or plant biology. In medicine, has its use, in the diagnosis of tumours, in reproductive and prenatal diagnosis, in transplants or in haematology. In our experimental work, we used this method to analyse colostrum and milk of sows. The aim of this study was to determine the number of somatic cells, the number of leukocytes and the number of T-lymphocytes. Colostrum samples were collected within 24 hours of delivery and then milk samples were collected at weekly intervals during 3 weeks. Statistical analysis revealed significant differences in the number of leukocytes (CD45+) in colostrum and milk. The most significant difference was noted between colostrum and milk in weeks 2 and 3 of the experiment (P < 0.0001), with the highest values found in colostrum. On the other hand, we found that the levels of helper T-cells (CD4+) and cytotoxic T-cells (CD8+) gradually increased over time (P > 0.05), with the highest values observed in the third week after farrowing. We can conclude that flow cytometry can be successfully used for the examination of somatic cells in sows’ milk.
Design of Experiment Applied in the Chemical Separation Process of Plastic and Aluminum Present in Aseptic Carton Packages
Authors: Silva Gisele Aparecida , Bosch Neto Juan Canellas , Nucci Edson Romano
Published: September 2024

Objective: This study aimed to investigate the separation of polyethylene and aluminum residue layers from Tetra Pak post-consumer packaging. This was achieved by facilitating a spontaneous reaction between aluminum and water, with the assistance of NaOH as a catalyst.
 
Theoretical Framework: Aseptic carton packaging is widely recognized as safe and high-quality in the food and beverage industry. This type of packaging offers several properties, acting as a barrier against gases, light, loss of flavor, and water vapor while providing shape and flexibility. These characteristics are achieved by combining plastic, paper, and aluminum. Despite the significant advantages of multilayer films, recycling this material presents challenges.
 
Methodology: During the initial planning phase, a 26-2 fractional factorial experiment was conducted to evaluate 6 different process variables: agitation (rpm), pre-treatment, NaCl concentration (g/L), time (minutes), temperature (°C), and NaOH concentration (mol/L). Subsequently, a second experimental design called the Design Central Composite (DCC) was implemented. The results indicated that only temperature and time remained statistically significant.
 
Results and Discussion: Based on the experimental results, were able to identify the most effective conditions for separating polyethylene and aluminum waste from Tetra Pak post-consumer packaging using response surfaces an optimal region can be defined with a minimum temperature of 50°C, a minimum time of 30 minutes, and a minimum NaOH concentration of 3 mol/L.
 
Originality/Value: This study adds to the existing literature by examining the application of experimental planning techniques in the chemical separation process of plastic and aluminum in Tetra Pak® packaging through two consecutive experimental plans.
Territorial Governance and its Challenges. Reflections on Inter-Municipal Consortia and River Basin Committees
Authors: Randolph Rainer
Published: September 2024

Objective: To identify, analyze and diagnose certain proposals for regional development policies and planning that have emerged in Brazil in more recent periods, which, as such, do not have their origins in formulation and implementation by the federal level.
 
Theoretical framework: With the involvement of different social and territorial scales, it became necessary to reflect on themes such as government, governance, planning and politics as a reflexive basis for the methodology.
 
Method: The characterisation of forms of territorial governance was carried out through the analysis and diagnosis of case studies on River Basin Committees and Inter-municipal Public Consortia as empirical experiences involving different scales of regionalisation.
 
Results and Discussion: Different levels and scales were uncovered in the involvement and triggering of management, from federal and state governments, to those originating in regional communities or even at municipal level and their different constraints and characteristics. Although the result of the limitation of these forms of management is not very surprising, it would be important to explore their potential for more democratic management in the future.
 
Implications of the research: A constructive study of the common criticisms of proposals for regional coordination through committees and consortia could reveal the conditions in which they can become potential arenas for the political game of regional development.
 
Originality/Value: In addition to contributing to the systematisation of the bibliography on the two forms of territorial management, it points to the need for further studies in search of their undiscovered potential.
Личностные основания профилактики неконструктивного рискового поведения подростков
Authors: Москвина Елена Владимировна
Published: September 2024

The purpose of the presented study is to describe the application of the basics of a personal methodological approach in the prevention of unconstructive risky behavior of adolescents. The interest of researchers and practitioners of pedagogy in studying the nature of the emergence of risky behavior in adolescents is associated with solving the problems of finding effective technologies for its prevention. The peculiarities of unconstructive risky behavior of adolescents include the fact that it begins as experimentation against the background of a demonstrated willingness to take risks. However, risky behavior can become entrenched due to the formation of a psychological complex in the structure of a teenager's personality. An active scientific search in this area is due to the fact that this form of behavioral manifestations carries a balance of positive and negative outcomes in relation to his life and health that is not obvious to a teenager. The analysis of the sources allowed the author to come to the conclusion that a personal approach in line with the prevention of unconstructive risky behavior of adolescents presupposes the teacher's attitude to the pupil as a person, as a self-conscious responsible subject of his own development and as a subject of educational interaction and is implemented through the principles of pedagogical expediency (defines a set of means to achieve a predictable goal, contributing to a positive result with a focus on the personality traits of the teenager himself) and conformity to nature (involves taking into account the natural characteristics of adolescence in the work, contributing to the emergence of behavioral deviations, and building a pedagogically appropriate preventive trajectory).

Freestanding Emergency Departments: Opportunities, Challenges, and Implications for Emergency Care Delivery in the Middle East: A review
Authors: Tashkandi Muhammad , Alotaibi Bader
Published: September 2024

Freestanding Emergency Departments (FSEDs) have become increasingly important in healthcare, especially in rural and hospital-consolidated areas. This review evaluates their impact on emergency care, focusing on patient satisfaction, the work environment for healthcare professionals, and their potential to reduce overcrowding in hospital-based emergency departments (H-EDs). It acknowledges the challenges in these areas, particularly in ensuring standardized, high-quality care. The review advocates for state-level legislation to establish uniform standards for FSEDs, incorporating criteria from the American College of Emergency Physicians (ACEP). It also addresses the need for FSEDs in underserved areas, noting their current tendency to be located in more affluent regions. Additionally, the review highlights the necessity for increased price transparency to differentiate FSEDs from other acute care options and to avoid contributing to higher healthcare costs. By addressing these issues and implementing recommended changes, FSEDs can enhance healthcare access while maintaining quality and efficiency in emergency care delivery.
Genetically-determined defects of T cell development
Authors: Notarangelo Luigi D.
Published: September 2024

Genetically determined defects of T-cell development comprise a heterogeneous group of conditions characterized by peripheral T-cell lymphopenia due to impaired intrathymic differentiation of T-cell progenitors. Collectively, these conditions are typically referred to as severe combined immune deficiency (SCID). In some cases (leaky SCID), residual function of the defective gene allows partial T-cell development. The vast majority of SCID disorders are due to genetic defects that affect the T-cell differentiation potential of hematopoietic stem cells, through a variety of mechanisms. However, some forms of SCID reflect impaired development or function of thymic stromal cells. A lack of peripheral T cells leads to increased susceptibility to severe infections since early in life. SCID is inevitably fatal unless immune reconstitution is achieved, most often through hematopoietic cell transplantation. Enzyme replacement therapy, gene therapy, and thymus implantation represent other forms of treatment in selected cases. The availability of newborn screening has greatly facilitated prompt recognition of SCID, which allows statistically significant improvement in survival after hematopoietic cell transplantation.

Authors: Thi Thanh Hai Pham , Giang Nguyen Thi Huong , Huyen Nguyen Thi , Hanh Pham Hong , Duong Truong Ngoc
Published: September 2024

This research aims to synthesize international experiences in applying technology in teaching according to the TPACK model (Technological Pedagogical Content Knowledge), in order to draw lessons and apply them to Vietnamese universities. This article uses a theoretical research method, mainly synthesizing and analyzing texts from research papers published in large databases including Science Direct, Scopus, and Google Scholar, using keywords such as "TPACK" and "application of technology in teaching". To effectively apply technology, educational technologists have developed modern teaching frameworks, including the TPACK model, which combines three elements: (i) Technological knowledge; (ii) Pedagogical knowledge; and (iii) Content knowledge. Teachers need to harmoniously integrate these three elements when applying the TPACK model. In Vietnam, there have been some recent studies on the TPACK model in universities; however, the number of studies is still limited. This research aims to synthesize and analyze relevant studies on the application of technology in teaching according to the TPACK model. International experiences serve as practical lessons for Vietnamese universities to adapt and apply appropriately to the TPACK model, integrating technology with content and pedagogical methods in teaching to meet current practical requirements.
Aspects of information and spiritual similarity of real and virtual spaces
Authors: Bryndin Evgeniy
Published: September 2024

The results of numerous studies demonstrate the possibility of using the same approaches to studying real and virtual space in the context of their spatial perception. The study of virtual space can be carried out using the same parameters as physical space, and they should be considered equivalent. Virtual space is only one of the strategies for information copying of real space, the result of an irresistible human need to expand the horizons of research. Virtual space does not pose any threat to reality if we interpret the virtual environment as a transformation of the real environment, a new way of studying the mutual penetration of the virtual and real worlds. Learning to navigate in virtual space leads to safer life in real space.

It is shown that in the case where all the parameters ( a i ) 1 ≤ i ≤ h are positive reals, there exists a neuronal recurrence equation of memory length h that generates a sequence of period Ω ⁡ ( e h ⁡ ( ln ⁡ ( h ) ) 2 3 ) . This result shows that in the case where all the weighting coefficients are positive reals, the neuronal recurrence equation exhibits a complex behavior.

Motivated by social insects, the possibility of evolving distributed control for a task requiring global coordination is investigated. The task is object clustering. A key aspect of this work is that a population of robot-like agents is allowed to select the cluster location. A detailed examination of how solutions evolved by a genetic algorithm are able to scale as key parameters are varied is presented, allowing commentary on the sensitivity of the evolved solution to changes in the environment. In most of the scaling experiments, the solution degrades gracefully about the evolutionary design point. However, in the case of constant-density scaling, the solution maintains its effectiveness as the problem is made larger.

A Complex System Model of Glucose Regulatory Metabolism
Authors:   Electronic mail address: neelakan@fau.edu, Neelakanta Perambur S. , Leesirikul Meta , Roth Zvi , Morgera Salvatore ,   Department of Electrical Engineering, Florida Atlantic University, Boca Raton, Florida 33431
Published: September 2024

Consistent with inherent characteristics of a complex system made of a large number of interacting units having deterministic as well as spatiotemporal attributes, a model is developed to represent the human glucose regulatory metabolism within a complex system framework. Essentially, the mass-flow relations pertinent to sugar transport (in the form of glucose), and sugar regulatory hormones (namely, insulin and glucagon) across various participant parts of the body are depicted as nonlinear (logistic) functions; and hence, the temporal growth of blood plasma glucose concentration as well as the rate of change of such concentration levels are derived and expressed in terms of a Bernoulli-Langevin expression, (which functionally depicts the associated nonlinearity whose spatial order is implicitly dictated by the underlying complexity of the processes involved). Simulated results based on theoretical formulations derived are validated with respect to available clinical data due to Cobelli and Mari [1, 2], whose deterministic model of mass-balance relation pertinent to glucose regulatory metabolism is modified and adapted into complex system considerations. The results illustrate the statistical spread with upper and lower bounds associated with the temporal excursions of glucose concentration and its rate of appearance in blood plasma. The outcome of this study, for example, can find applications in refining predictive control algorithms adopted in closed-loop glucose control regimens (via insulin infusion pumping) prescribed to maintain normoglycemia in Type I diabetic patients.
Synchronization in Electrically Coupled Neural Networks

This report investigates the synchronization of temporal activity in an electrically coupled neural network model. The electrical coupling is established by homotypic static gap-junctions (connexin-43). Two distinct network topologies, namely: sparse random network (SRN) and fully connected network (FCN), are used to establish the connectivity. The strength of connectivity in the FCN is governed by the mean gap-junctional conductance (μ). In the SRN case, the overall strength of connectivity is governed by the density of connections (δ) and the connection strength between two neurons (S0). The synchronization of the network with increasing gap-junctional strength and varying population sizes is investigated. It is observed that the network abruptly makes a transition from a weakly synchronized to a well synchronized regime when (δ) or (μ) exceeds a critical value. It was also observed that the (δ, μ) values used to achieve synchronization decrease with increasing network size.

Apresentação do caso: Apresentamos o caso de uma paciente de 59 anos com transtorno bipolar há dezessete anos que apresentou pela primeira vez alucinações musicais somente treze anos após o início da doença. Posteriormente, contudo, essa forma especial de alucinação tornou-se recorrente e passou a estar associada a cada novo episódio afetivo que ela iria apresentar. Discussão: As alucinações musicais são raramente encontradas no transtorno bipolar e no presento caso clínico, no que se refere às alucinações musicais, houve uma boa resposta terapêutica, relacionada ao uso de um antipsicótico e a medidas comportamentais. Um aspecto peculiar do caso foi que, na depressão, essas alucinações consistiam em músicas tristes, e, na mania, em músicas alegres.
Performance Estimation of a Capillary-Fed Evaporative Microthruster
Authors: Sharma Akshay , Singh Tarun , Panda Pratikash , Dash Susmita
Published: September 2024

Nanosatellites are important for carrying out short-term and cost-effective communication and surveillance missions. Their small size necessitates the need for propulsion systems that are lightweight, compact, and capable of delivering accurate reaction and attitude control while allowing for seamless integration with the satellite. This paper reports on a numerical analysis to determine the performance of a micro-electromechanical system (MEMS)-based vaporizing liquid microthruster that utilizes microtextured substrates for passive feeding of the propellant (water) using capillary force and subsequent thin film evaporation by localized heating. The generated vapor flows through a converging nozzle to produce thrust. The performance of the propulsion device is evaluated in terms of the mass flow rate, thrust, and specific impulse. The model demonstrates a unique way of integrating the evaporation characteristics at the liquid–vapor interface to real nozzle flow dynamics. The evaporation phenomenon at the liquid–vapor interface is captured by utilizing kinetic theory of the gases, and real nozzle flow is analyzed by considering compressible-slip flow through the converging nozzle. It is shown that the microthruster can generate a thrust of [Formula: see text] and an specific impulse of [Formula: see text] with a power input of approximately 3 W. The thrust and specific impulse efficiencies, when compared to quasi-one-dimensional isentropic values, are determined to range between [Formula: see text] and between [Formula: see text], respectively, for a power input of 0.2–3 W.
Modeling of a Thermoacoustic Flue Gas Analyzer
Authors: Elseoud Mohab Abo , El-Rahman Ahmed Abd , Saleh Hindawi
Published: September 2024

Reliable monitoring of industrial flue gases is essential for maintaining optimal combustion efficiencies, and thus lesser environmental impacts, in the processing of typical combustion systems. Typical modern-day sensors rely in their operations on either electrochemical or nondispersive infrared technologies. Although such technologies are well established, they also have their drawbacks, which include the relatively high cost, drift effects, the need for frequent calibration, and limited lifetime. This study investigates the performance of a proposed self-powered thermoacoustic flue gas analyzer, where the exhaust gas is introduced into a compact resonator containing a porous medium, commonly known as the stack. Quasi-steady temperature distributions are allowed to develop along the stack under controlled heating/cooling. At a certain axial temperature gradient, self-sustaining thermoacoustic instabilities are induced inside the resonator that help determine the molar concentrations of quaternary gas mixture components. Here, the existing theoretical framework is first revised by addressing some of its underlying linear approximations. The improved algorithm is then applied to a large number of gas mixtures for the development of more realistic operational ternary diagrams. The present theoretical model achieves a [Formula: see text] increase in the onset temperature difference span and hence better detection capability for the flue gas analyzer compared to the original theoretical model. Next, a two-dimensional computational model is constructed and tested where the present predictions show good agreement with the reported experimental results at low mean pressures, which demonstrates the validity of the adopted theoretical model.
History of music, electromagnetism and the Sun: an innovative educational resource for pre-service primary school teachers
Authors:   Universidad de La Laguna (España), Eff-Darwich Antonio
Published: September 2024

In general, science education programs for pre-service primary teachers encounter several challenges, including inadequate subject matter training and uninspiring lectures. This results in a disconnection between university learning and real-school experiences. To address these issues, an innovative science teaching course for primary school teachers is proposed. This course emphasizes interdisciplinarity, practical activities and didactical resources, with the ultimate goal of breaking the cycle of unmotivated and unskilled students by producing competent and enthusiastic science teachers.

В статье предложена математическая модель для оценки эффективности подготовки специалистов по информационной безопасности, использующая временные характеристики образовательного процесса. Обоснована метрика для оценки соответствия характеристик образовательного процесса их требуемым значениям. Используется процессный подход к оценке качества информационной деятельности. На основе таких параметров образовательного процесса, как объем обрабатываемой информации и время ее обработки, сформирован показатель эффективности подготовки специалистов. Причем, время обработки информации определяется как случайная величина. Все математические выкладки выполнены в терминах случайных величин, что позволило авторам рассматривать выполнение ряда условий и ограничений как случайные события и, соответственно, перейти к вероятностной модели описания событий. Предложенный и математически обоснованный в статье показатель может быть использован в дальнейшем при решении задач оптимального управления процессом подготовки специалистов как в области информационной безопасности, так и в других областях.

The article proposes a mathematical model for evaluating the effectiveness of training specialists in the field of information security, using the time characteristics of the educational process. The metric for estimation of conformity of the educational process characteristics to their required values is been proved. A process approach is used to assess the quality of information activities. On the basis of such parameters of the educational process as the amount of information processed and the time of its processing, the effectiveness indicator of specialists training is formed. Moreover, the time of information processing is determined as a random variable. All mathematical calculations are performed in terms of random variables, which allowed the authors to consider the fulfillment of a number of conditions and restrictions as random events, and, accordingly, to move to the probabilistic model of describing events. The proposed and mathematically justified effectiveness indicator will be used in future problems solving for the new specialists training process and its optimal control in the field of information security and in other areas.

Организация структуры хранения информации и обеспечения оперативного доступа к данным это наиболее сложные вопросы, с которыми сталкиваются предприятия: от небольших частных организаций, до крупных государственных корпораций. Еще недавно средний объем данных, с которыми работают различные организации, варьировался в пределах десятковсотен терабайт. Но уже сегодня, многие крупные организации работают с петабайтами информации, стремительно увеличивая ее объемы. Для хранения информации используются различные накопители: от магнитных лент и оптических дисков, до высокоскоростной флэшпамяти. От типа накопителя зависят важные технические характеристики всей системы. Тип накопителя зависит от оборудования, которое, в свою очередь, зависит от выполняемых задач, таких как оперативное хранение, долговременное хранение, обработка и т. д. В данной работе будут рассмотрены основные накопители информации, их преимущества и недостатки, влияющие на структуру хранения информации.

Organizing the structure of storing information and en suring prompt access to data is the most difficult issues faced by enterprises: from small private organizations to large state corporations. More recently, the average amount of data that various organizations work with has ranged from tens to hundreds of terabytes. However, today, many large organizations are working with petabytes of information, rapidly increasing its volume. For storage of information using different drives: from magnetic tapes and optical discs to highspeed fl ash memory. The important technical characteristics of the entire system depend on the type of drive. The type of drive depends on the equipment, which, in turn, depends on the tasks performed, such as operational storage, longterm storage, processing, etc. In this paper, we consider the main storage devices of information, their advantages and disadvantages affecting the structure of information storage.
