«Lace Miracle», lichens as an indicator of the ecological situation using the example of Turkey Creek, Florida
Authors: Poleva J. L. , Polev M. D.
Published: September 2024

In this article, we took a walk-exploration of a piece of paradise called Turkey Creek in the center of Florida. Enjoying the spring period of the awakening of nature, accompanied by a multitude of birds and other unique sounds of the inhabitants of Turkey Creek, we paid special attention to the diversity of lichens, which, as bioindicators, react and reflect the state and quality of the environment. Lichens are very sensitive to air pollution and die when there is a high content of carbon monoxide, sulfur compounds, nitrogen and fluorine. The degree of sensitivity varies among species, so they can be used as living indicators of environmental cleanliness. Based on the composition of lichens, the concentration of various pollutants in the air can be quantified using developed scales and formulas. Lichens are a unique group of lower plants. Lichens combine two organisms with opposite properties: an alga (usually green), which creates organic matter through the process of photosynthesis, and a fungus that consumes this substance. Lichens are characterized by fairly high tolerance to climatic factors and sensitivity to environmental pollutants and are widely used as environmental indicators. Lichens contain many macro- and microelements, organic acids, hormones and enzymes. Vitamins are produced by lichens in very small quantities. Lichens produce specific substances that are not found in other organisms (lichen starch, lichen acids, etc.). Lichens have the ability to extract various elements from the environment and accumulate in their thallus. The number of currently known lichen substances exceeds 250, of which 75 are found only in lichens. Lichens are indicators of the environmental situation. Our goal is to find out whether recreational load affects the state of the environment in people’s recreation areas. We carried out our study of the state of the environment in the state of Florida in the Turkey Creek natural park. This territory was chosen because the natural complexes of the area are characterized by high environment-forming, environmental, and recreational significance. In the last decade, the anthropogenic load on ecosystems associated with the recreational use of the territory has been increasing. It is worth familiarizing yourself with the types of lichens that were seen in the study area.

Authors: Buleyko A. A.
Published: September 2024

The study of the influence of chemicals in the aquatic environment on the nutrition of fish, which lead to gradual pollution of the aquatic environment and violation of living conditions, and the development of methods for improving the nutritional properties of fish, which is an important branch of science that combines fish biology, in-depth study of nutrition and rational management, has been established fish resources and environmental sustainability. In recent years, a significant amount of research has been conducted aimed at understanding the relationships between fish nutrition, their development and the quality of fish products, the influence of chemicals on these processes in today's conditions using the example of carp (Cyprinus carpio L.). Analyzing the data, it was found that the quality of fish nutrition depends on the quality and composition of water, which affects the growth, development and health of fish. Considering the requirements of nutrients such as proteins, fats, vitamins and minerals, good nutrition can improve the quality of fish production. Special attention is paid to the role of proteins in the metabolism of fish using the example of cyprinus carp (Cyprinus carpio L.), growth and development, as well as adaptation to the interesting study of the composition of tissue proteins of carp during cadmium and lead intoxication. This year's carp (Cyprinus carpio L.), which is a widespread object of pond culture in Ukraine, was used for the experiment. A detailed analysis indicates that taking into account the effect of toxic substances on fish nutrition is necessary to ensure their health and optimal fish production. The development of new feeding strategies and the use of special additives is becoming a key aspect not only for improving the quality of products, but also for ensuring compliance with safety standards and environmental sustainability in the field of aquaculture and fisheries. Such research identifies new ways to create sustainable and healthy fish populations, contributing to the coordinated development of the agro-industrial sector and the preservation of aquatic ecosystems.

Authors: Mejía-Cepeda Natalia , Murillo-García Óscar , Bolívar-García Wilmar
Published: September 2024

Introducción: La comunicación acústica es esencial en las comunidades de anuros, especialmente para la reproducción. No obstante, el espacio acústico es limitado y las interferencias bioacústicas, como la competencia por apareamiento y recursos, afectan la eficacia de la comunicación. El bosque seco tropical en Colombia alberga especies de anuros que han sido resilientes a la gran reducción, fragmentación y transformación de este en las últimas décadas. La investigación escasa en este tema subraya la importancia de la caracterización acústica de los ensamblajes de anuros, para comprender la coexistencia de especies, monitorear cambios en la comunidad y evaluar el impacto tanto de especies invasoras como de la actividad humana en el ecosistema. Objetivo: Caracterizar acústicamente un ensamblaje de anuros del valle del río Cauca. Métodos: De septiembre a noviembre de 2022 (temporada lluviosa), se tomaron registros acústicos con sensores acústicos pasivos y activos de una comunidad de anuros del valle geográfico del río Cauca, en el flanco occidental de la cordillera central de Colombia. Se analizaron los cantos de anuncio en tres dimensiones: parámetros espectrales, temporales y patrones de actividad acústica. Resultados: Se registraron cinco especies de anuros, sus cantos presentaron un alto solapamiento en actividad, pero grandes diferencias estructurales, las especies tuvieron actividad nocturna a excepción de una de la familia Dendrobatidae. Conclusiones: Cada especie presenta un nicho acústico particular que evita el traslape en las señales acústicas, y estos resultados proporcionan una línea base para evaluar futuros cambios en el ensamblaje.

Authors: Rosas-Mejía Madai
Published: September 2024

Introduction: The creation of protected natural areas within urban environments has played an essential role in providing small reservoirs of native vegetation and refuges for endemic species. Objective: To analyze, through ant communities, the influence of urbanization in a protected natural area (PNA) located in an urban zone. Methods: From April to July 2022, using bait traps and pitfall traps along 100 m transects, the presence of ant species was recorded in the El Refugio State Park Natural Area in Tamaulipas, Mexico. Alpha diversity was assessed using Hill numbers, while beta diversity was evaluated using the Jaccard index. Additionally, indicator species were identified through the indicator value (IndVal). Multiple correspondence analysis was conducted to associate the presence of species with environmental variables and vegetation types, and contingency tables were created to relate ant presence to vegetation cover size. Results: Species richness and diversity decreased in sites with low vegetation cover, such as in Tamaulipan thornscrub; moreover, secondary vegetation retained greater species richness. Indicator species were found in secondary vegetation and grassland areas, mainly composed of species that tolerate high temperatures and generalists such as Forelius mccooki and Tetramorium spinosum, while lowland jungle species were the only indicator species. The presence of these species is primarily associated with temperature, humidity, and vegetation cover. A significant relationship between the presence of ant species and vegetation cover size in El Refugio State Park was evident. Conclusion: The structure and composition of ant communities vary according to the type of vegetation structure, particularly in areas that have undergone greater anthropogenic damage. Therefore, the conservation of landscapes, as well as monitoring of these areas, should be considered in future research.

Reflecting on a Decolonial educational praxis in South African public schools
Authors: Hendricks P
Published: September 2024

The continuing educational crises and the recurrent discourse on educational reform in South Africa foreground critical questions on what constitutes a viable philosophical and pedagogical strategy for the country. This article examines the transformative praxis of a dissident teachers' organisation, the Teachers' League of South Africa (TLSA or the League), and how the development of its distinctive non-racist and non-collaborationist worldview provide meaningful possibilities for present-day educationists seeking a progressive educational alternative. The article draws on decolonial and critical education theories to engage the views of TLSA teachers and non-League education activists. Documentary material on the TLSA and its umbrella body, the Unity Movement, provide key primary sources for the article. In addition, secondary information linked to the broader liberation movement offers valuable insights and perspectives on what could be defined as an alternative educational praxis. Overall, the article examines whether the coexistence of the TLSA's holistic educational outlook and 'egalitarian oriented' counter-consciousness, offers tangible possibilities for exploring an emancipatory decolonial education.
Laws of conservation of mass and momentum for an ideal fluid in the inertial framework of special relativity
Authors: Alva Castillo Gilberto Sebastián , Maco Vásquez Wilson
Published: September 2024

In the realm of Newtonian fluids, fundamental conservation laws such as those governing mass, momentum, and energy are rigorously upheld within absolute reference frames. However, within the framework of special relativity and the concept of space -time, the notions of separate conservation of mass and momentum no longer hold. Instead, the theory relies on Lorentz transformations and relative reference systems, typically denoted as S and S', moving uniformly relative to each other, each with its own temporal framework. Within the context of special relativity, particularly in the study of particles, significant findings pertain to the energy-momentum vector. These findings underscore the necessity, when studying fluids within inertial frames, to apply conservation principles to the energy-momentum tensor.

Authors: Godoy Jeane Aparecida Rombi de , Palmisano Angelo , Tarachuk Marcelo Luiz Perini
Published: September 2024

The aim of this text is to analyze the environmental and social risks that the Amazon faces due to the expansion of economic activities and the exploitation of natural resources, focusing on the need for integrated policies and sustainable actions to preserve the biome. The Amazon, considered the lungs of the world, is vital for global climate regulation and biodiversity. However, it faces severe threats from deforestation, climate change, and economic pressure. The study is justified by the urgency of finding solutions that balance economic development with environmental preservation, preventing irreversible damage from occurring. The work was conducted through a comprehensive literature review, analysis of environmental and socio-economic data, and case studies on the implementation of public policies in the Amazon region. The interdisciplinary approach allowed an integrated understanding of the environmental, social, and economic impacts of human activities in the Amazon. The results indicate that, despite advances in some conservation areas, the expansion of agricultural frontiers and the exploitation of natural resources continue to exert significant pressure on Amazonian ecosystems. The study highlights the importance of more effective public policies and international cooperation to mitigate the impacts. The study concludes that the preservation of the Amazon requires a multifaceted approach that includes targeted conservation policies, incentives for sustainable economic practices, and greater participation of local communities. Only through coordinated actions will it be possible to ensure the sustainability of the biome and its essential ecosystem services for the planet.

Authors: Zinina E. V. , Bulakh M. V. , Ryzhkova O. P. , Shchagina O. A. , Polyakov A. V.
Published: September 2024

Background. Duchenne muscular dystrophy (DMD) is the most common form of muscular dystrophy in children, that occurs between one and three years of age. DMD is caused by pathogenic and likely pathogenic variants in the DMD gene, which lead to a deficit of various isoforms of the dystrophin protein, the main protein of the muscle cytoskeleton. Drugs aimed at slowing the progression of the disease are being actively developed around the world. One of the perspective approaches to pathogenetic therapy is therapy using exon skipping. As a result of this treatment, the reading frame is restored due to the exon skipping enabling the production of truncated dystrophin.

Aim. To evaluate the applicability of exon skipping therapy in Russian patients with DMD.

Materials and methods. The applicability of therapy aimed at exon skipping was analyzed for a sample of 1519 patients admitted to the laboratory of DNA diagnostics of the Research Centre for Medical Genetics with a referral diagnosis of Duchenne/Becker muscular dystrophy from October 1, 2018 to September 1, 2023.

Results. As a result of the study and analysis of the spectrum of mutations in the DMD gene among patients with DMD in the Russian Federation, the theoretical applicability of exon skipping therapy was assessed: for 29.3 % of patients this approach to treatment is applicable. The proportions of patients for whom existing exon skipping therapies are available were also estimated. In total, skipping of frequent exons 51, 53, 45 is applicable for 14.6 % of patients. Conclusion. One of the effective and accessible types of therapy for DMD is exon skipping. This type of therapy is mutation-specific. In this regard, the assessment of applicability will allow us to estimate the proportion of patients for whom a particular exon skipping will be available.
SMArt Retro study: a retrospective data analysis of the Russian registry of patients with spinal muscular atrophy
Authors: Vlodavets D. V. , Shchagina O. A. , Polyakov A. V. , Kutsev S. I.
Published: September 2024

Background. Existing registries of patients with spinal muscular atrophy (SMA) 5q serve as a valuable source of information on identified patients. Information on the characteristics of Russian patients with SMA 5q and the therapy administered in real clinical practice is currently limited.

Aim. To describe a cohort of Russian patients with a confirmed diagnosis of SMA 5q and to evaluate patient routing data in real clinical practice settings in Russia.

Materials and methods. The present study was a descriptive non-interventional retrospective cohort study in patients diagnosed with SMA 5q who were enrolled in the Russian patient registry between January 1, 2020 and March 31, 2023. Study participants who met the inclusion criteria were automatically identified in the integrated database of the SMA 5q patient registry. Data were uploaded into validated electronic charts, verified and analyzed using descriptive statistics methods. Results. As of March 31, 2023, the Russian SMA registry contained information on 1408 patients from all federal districts and obtained epidemiological, sociodemographic and clinical characteristics of patients, as well as routes to diagnosis and treatment regimens for patients. The median time from disease onset to confirmed diagnosis was 3 months in patients with SMA type 1, 9 months in patients with SMA type 2, 20 months in patients with SMA type 3 and 68 months in patients with SMA type 4. The median time from confirmed diagnosis to the start of disease-modifying therapy was 0.5 months in SMA patients identified by neonatal screening, 21 months in patients with SMA type 1, 59 months in patients with SMA type 2, 47 months in patients with SMA type 3 and 87 months in patients with SMA type 4.

Conclusion. This retrospective analysis was carried out in order to identify recent approaches to the diagnosis and treatment of SMA used in real-world clinical practice in Russia. The identified parameters (duration from the disease onset to confirmed diagnosis, duration from the confirmed diagnosis to disease-modifying therapy initiation) indicate that more widespread use of newborn screening and more rapid treatment initiation are unmet needs for SMA patients in Russia.
Newborns’ routing organization in subjects of the Russian Federation
Authors: Ivanov Dmitry O. , Yakovlev Alexey V.
Published: September 2024

Reduction of infant mortality is a priority task for achieving the national development goals of the Russian Federation. The paper analyzes the influence of regional routing of newborns on the infant mortality rate in the subjects of the Russian Federation. The infant mortality rate for the period January–November 2023 in the Russian Federation is below the target value and amounts to 4.1‰, which is lower than the rate for the same period of 2022 (4.3‰). At the same time, subjects implementing insufficiently effective intraregional routing of newborns have a high rate of neonatal deaths in the early and late neonatal period concerning medical organizations of the I and II level of medical care. In order to improve the availability and quality of medical care for newborns, as well as to reduce the number of re-hospitalizations of newborns between medical organizations of the same level, including those requiring emergency surgical correction, it is necessary to update regional and interregional routing schemes in the provision of care to newborns, taking into account the orders of medical care, principles of territorial planning (with a detailed description of the areas of responsibility of each medical organization located on the territory of the subject).

Authors: Aleksandrovich Yurii S. , Ivanov Dmitry O. , Pshenisnov Konstantin V. , Sterlyagova Ekaterina V. , Fomin Sergey A.
Published: September 2024

Corticosteroids are widely used in clinical practice in the care of children in critical condition, but data on their efficacy in neonatal practice are very limited. This publication attempts to summarize and systematize the literature data on the use of exogenous corticosteroids in various diseases of the neonatal period. Special attention is paid to the pathophysiology of acute adrenal dysfunction in the structure of critical conditions, its diagnosis and treatment. The results of a number of studies confirming the effectiveness of various corticosteroids in neonatal cardiac surgery, arterial hypotension, neonatal sepsis, refractory septic shock, meconium aspiration syndrome and bronchopulmonary dysplasia are presented. It has been demonstrated that hydrocortisone is the drug of choice in critical situations due to its minimal half-life and low probability of side effects. It has been established that current data on the feasibility, efficacy and safety of corticosteroid use in critical conditions of the neonatal period are very controversial and require further experimental and clinical studies. The question of the necessity of corticosteroids use in neonatal cardiac surgery and in various lung diseases (meconium aspiration syndrome, bronchopulmonary dysplasia) remains open, although there is enough evidence of their positive therapeutic effect, but there are no randomized multicenter studies, which limits the use of corticosteroids in clinical practice. An absolute indication for the administration of corticosteroids in neonates is the presence of acute adrenal insufficiency, congenital adrenal cortical hyperplasia and catecholamine-resistant septic shock.

Authors: Sutrisno Himawan Hadi , Faizah Farhah Al , Sari Yunita , Husaini Layla Najwa , Audrya Anissa Intan
Published: September 2024

Carbon Fiber Reinforced Polymer (CFRP) composites are widely used in major manufacturing industries, including the robotics industry. To provide robot technology protection against high temperatures, composites with good thermal resistance are needed. The thermal resistance is completed by adding a refractory material in the form of silica from Rice Husk Ash (RHA). This research was conducted to determine the effect of adding silica on the thermal resistance of CFRP composites using the vacuum bag method. The CFRP itself is made of composite samples using polyester resin, woven carbon fabric, and silica extract with composition variations: 0 g (without silica), 5 g, 15 g, 25 g, and 35 g. CFRP is tested using Thermogravimetric Analysis (TGA). Based on the research results, it can be concluded that the addition of 35 g of silica from rice husk ash can increase environmental temperature resistance up to 414.2 °C. The increased environmental temperature resistance of this composite material will be very suitable for use in robotics components that are in direct contact with heat temperature.

Published: September 2024

The production sugarcane of superior varieties can be achieved through cross-breeding between superior parent plants based on the desired advantages. This research examines the diversity of superior clones SB04, SB11, SB19, and SB20, and identifies which clones have the highest productivity potential. The first ratoon research was carried out from August 2020 to July 2021. Data analysis used descriptive-analytic methods, regression tests, and genetic diversity assessment. Observation variables include agronomic variables and potential productivity. The findings show the genetic diversity of the superior clone SB04 showed close similarity to the heterozygous combination PS862. The superior clone SB11 showed a tendency to inherit traits similar to Cenning Elder. The superior clones SB19 and SB20 lean towards the VMC71-238 variety and the combination of PSBM01 and VMC71-238. The superior clones SB04, SB11, SB19, and SB20 produced higher variable weight, yield, and sugarcane crystal weight compared to the characteristics of their two parents. These clones—SB04, SB11, SB19, and SB20—produced high crystallization yields, ranging from 8.47 to 15.26 tonnes/ha, higher than their parent plants. SB19 has the highest yield, namely 15.26 tons/ha. Although some clones dominate crystal production, other clones inherit traits from both parents but are less dominant in overall productivity.

Published: September 2024

The article presents a method for reconstructing and animating a digital model of a human head from a single RGBD image, a color RGB image with depth information. An approach is proposed for optimizing the parametric FLAME model using a point cloud of a face corresponding to a single RGBD image. The results of experimental studies have shown that the proposed optimization approach makes it possible to obtain a head model with more prominent features of the original face compared to optimization approaches using RGB images or the same approaches generalized to RGBD images.

Authors: Munir Buyung Sofiarto , Trisetyarso Agung , Reza Muhamad , Abbas Bahtiar Saleh
Published: September 2024

Power system oscillation is one of the phenomena that can cause problem in power system that can even lead to outage. Using data of phasor sifting in power system available through Phasor Measurement Unit (PMU) implementation, power system oscillations could be observed directly. However, to predict the condition of power system, the recorded phasor data need to be processed to obtain the quantitative measures. In this paper, important parameters are extracted by applying Hilbert Huang Transform (HHT) to phasor signal taken from PMU. The stable and oscillation condition are determined by the parameters that show the increasing power of each frequency over period of time. Validation is conducted by using simulation data that represents characteristic of PMU data.

Authors: Marković Maja Gligora , Debeljak Sandra , Kadoić Nikola
Published: September 2024

One of the main goals of the General Data Protection Regulation (GDPR) is to protect the personal data of individuals. Each organization (company, association, school, institution, university, etc.) has an obligation to protect all of the individual data that it obtains. Those data can belong to employees, members, students, clients, etc. The research in this paper is related to the higher education students in Croatia.
This study is being conducted in three parts. The first part was conducted in April of 2017 (N=159) and the second in April/May of 2018 (N=141), in a period before the GDPR became valid (May 25th, 2018). In this paper, we are analysing the results of the second part of the study. Additionally, we are discussing risks that might appear if students do not know the GDPR. Risk matrix results are used to represent a basis which higher education administrations can utilize to make corrective decisions. The main conclusion of the research is that there are still issues with understanding the basic concepts of personal data and the GDPR, which may cause some problems during studying process. The main recommendation for HEIs or students organizations (such as student councils) is to organize lectures and workshops related to the GDPR.

In the university, course scheduling and preparation for each semester can be defined as the process of determining what courses to offer, the number of sections needed for each course, assigning of a faculty member to teach each section, and allocating a timeslot and a classroom for each section to avoid clashes. The output of this activity (which is a timetable) affects every faculty member and student in various departments. This process is essentially broken down into three main stages: determining the courses to be offered as well as their section numbers, assigning faculty members to different sections, and scheduling of the sections into timeslots and classrooms.
This paper investigates each of these steps and congregates them in a scheduling and Decision Support System (DSS). The DSS is used to make easy the process of course offerings by taking into consideration the students’ suggestions because the department resources are limited. The faculty member preferences are also considered in the assignment of sections for the sake of lessening disappointments in the department. Also, the couples (faculty, section) are planned into university timeslots based on faculty member preferences. Our proposed system considers student suggestions and preferences and the time availability of a faculty member since it minimizes disappointments and avoids conflicts between faculty members and classrooms and courses.

Constantly changing and developing technological life eases life on one hand, and creates new risks on the other. In the 21st century which is termed as “the age of technology”, computer and internet usage have become indispensable elements of life. Internet addiction has recently emerged as a new type of addiction which came to the agenda with technological developments. Failing to impose restrictions on internet usage, continuing to use it despite its social and academic damages and suffering from excessive anxiety when access to internet is restricted are symptoms of this new type of addiction and is one of the first examples of digital disease types which entered psychiatry literature as of 1990s. These types of recently-defined digital diseases which can be seen at almost every age have turned into a risk factor especially for 12-18 age group. The purpose of this article is to examine the types of digital diseases which emerge out of social media usage and problematic usage as a result of digitalization.

With our technology we measure every physical change or phenomena in our world. Using large collection of algorithms, we process, analyse, calculate, and gather results of every measured physical change. In that way a large database of raw data is created. The idea is to make a program that will understand our input data and make all calculations that we need. For that operation, we want to distinguish the “LabView” by National Instruments. LabView creates Virtual Instruments (VI’s), so, we can use the same VI’s for different type of input data with small change in parameters and filters according to the type of the data.

Faculty evaluation is widely used not only for the appraisal of their performance, but also for curriculum innovation and development. There are many techniques to perform faculty evaluation. But these techniques do not address all the factors essential for evaluating a faculty. These evaluations are subjective in nature and found to be controversial as students’ expectations vary. This hinders the main motive of faculty evaluation. To overcome this problem, there is a need to identify a suitable method to perform faculty evaluation. In this paper, the Conjoint Analysis, a mathematical statistics technique is used to analyze the major aspects that the students are expecting from their faculty. This technique increases the fairness in the appraisal process so that teaching can be made fun and effective. This research is a novel attempt that applies conjoint analysis to identify the major aspects of teaching in students’ perspective. The proposed idea can be adapted to any domain where the customers’ choice is valued particularly in Cloud computing services.
