Authors: Lind Emily , Lind Eric
Published: December 2024

Climate change research and environmental activism are critical to the long-term health and safety of all people. Canadian populations face considerable risk from events such as coastal erosion, forest fires, droughts, and more. Youth climate activism is experiencing a zeitgeist which may positively impact research in this area. This paper explores publication trends in the Canadian Science Fair Journal to explore the locations, age groups, research topics and other key factors of science fair reports published between 2018 and 2022. From this analysis, we conclude that Canadian youth are keenly aware of how their research can generate solutions to climate change, and that they approach the issue from many perspectives. However, efforts must be made to further mobilize specific provinces, provide avenues for entrepreneurship, and increase networking to foster the next generation of Canadian climate scientists.

The mango is today one of the five most produced and consumed fruits in the world after the orange, the banana, the grape and the apple. It is one of the three most exported fruits from Côte d’Ivoire with banana and pineapple. However, the mango sector faces enormous post-harvest losses due to diseases and handling activities. It is in this context that the objective of this work is to reduce post-harvest losses of the Amélie variety mango, using formulations based on biocontrol agents (Pseudomonas fluorescens and Bacillus subtilis) against fungal germs spoilage. To do this, isolation and identification of spoilage fungal strains on 50 spoiled Amélie variety mangoes were carried out. Two liquid formulations based on the two biocontrol agents were produced and tested on the isolated fungal strains. The results of this study showed that Colletotrichum and Lasiodiplodia were identified as genera responsible for mango spoilage. In vitro antagonist tests carried out with the formulations inhibited the growth of Colletotrichum and Lasiodiplodia. The inhibition rates of the Bacillus subtilis formulation were between 76.63% and 89.06% and those of Pseudomonas fluorescens were 78.21% to 83.57%. For the consortium (Bacillus subtilis + Pseudomonas fluorescens), the inhibition rates of the formulations were between 87.73% and 88.97%. Therefore, Bacillus subtilis and Pseudomonas fluorescens could be used as biocontrol agents in the fight against fungal spoilage of mango in Côte d'Ivoire.

Enhancing cyber security using quantum computing and Artificial Intelligence: A review
Authors: Abdullah Hill Hussain  , Md Nayeem Hasan  , Nayem Uddin Prince  , Md Maruful Islam  , Sanjida Islam  , Syed Kamrul Hasan
Published: December 2024

The rapid development of cyber threats calls for solutions to bolster cyber security frameworks. This article reviews how Quantum Computing (QC) and AI are already beginning to address the criticisms cyber security systems typically take. Classical computing, which processes data sequentially using algorithms that are based on deterministic logic, confronts constraints from both scales and is efficient when dealing with massive datasets, resulting in slower threat detection times and a higher frequency of false positives. What's different is that quantum computing uses quantum mechanics to make data processing faster and more accurate. Using techniques like superposition and quantum-enhanced algorithms can deliver more precise threat analysis in a shorter period than can be achieved with classical methods. Quantum Machine Learning (QML) techniques such as quantum support vector machines (SVM) and variational quantum circuits handle big datasets much more efficiently than classical methods, so they enable better threat detection. Entrepreneurs also benefit from AI methods based on artificial intelligence via learning mechanisms that can automatically detect anomalies in a synergistic relationship with quantum developments to improve the accuracy of threat classification and response. With the combination of quantum algorithms and AI, cybersecurity is expected to see significantly enhanced speed, accuracy, and scalability, especially in large-scale deployment scenarios. However, problems still exist in the implementation of quantum technology - such as the need for compatible hardware and developing cryptographic methods that are in quantum times ahead. This paper points out how QC and AI could reinvent cyber security and provides an agenda that future research must take up in these areas.

Authors: Fathony Arsyad  , Muhammad Zulfadli Syahrul
Published: December 2024

High Flow Nasal Cannula (HFNC) is a non-invasive oxygen therapy device with high flow that is increasingly used to treat patients with acute respiratory failure, especially in hypoxemic cases. HFNC offers several advantages, such as optimal humidification, reduced breathing work, and increased oxygenation, reducing the need for invasive mechanical ventilation. This paper aims to elucidate the mechanism of action, indications, clinical monitoring, benefits, and potential risks of HFNC use in adult patients with various clinical conditions. HFNC has various beneficial physiological effects, including increasing oxygenation by reducing anatomical dead space and producing end-expiratory positive pressure (PEEP). The main indications for HFNC include acute hypoxemic respiratory failure, post-extubation, and patients with “do not intubate” (DNI) status. In addition to its benefits, HFNC has risks, such as delayed intubation, hypercapnia, and gastric inflation, requiring close monitoring. HFNC is an effective and easily tolerated modality for treating mild to moderate acute respiratory failure. However, more research is needed to determine optimal use criteria and guidelines for therapy escalation.

Published: December 2024

Phages have diverse applications in the domains of therapeutics, diagnostics, bioremediation, and biotechnology. Coliphages are a group of viruses that infect coliform bacteria. In the last decade, coliphages have gained significant attention for their application in sewage water treatment as a tool to reduce coliform load. The main objective of this study was to treat sewage water with coliphage and evaluate it for reduction in coliform count. In the current study, isolation, enrichment, and enumeration of coliphage was carried out from a sewage sample. The titre of the enriched phage lysate was estimated to be 4.89 x 107 pfu/ml. The pre-treated sewage sample was quantitated for coliform count by the Most probable number (MPN) method, and the count was found to be >2400/100 ml. Post-treatment, the MPN of the phage-treated sewage sample was found to be reduced. After eight hours of incubation, an 80-fold reduction (30 org/100 ml) in MPN count was observed for the treated sewage sample. Chemical oxygen demand (COD) of pretreated and post-treated sewage samples was estimated, and the efficiency of the treatment was calculated to be 50.01%. The current study suggests the application of bacteriophage as a complementary tool for the reduction of coliform in wastewater along with other treatment procedures.

Authors: Sapsudin Asep , Qohar Hendri Abdul
Published: December 2024

Inclusive and equitable higher education is an urgency that cannot be overlooked, especially in efforts to guarantee the human rights of persons with disabilities. Legal reform is essential to create an educational environment that supports equal access, as mandated by Law No. 8 of 2016 and Government Regulation No. 13 of 2020. The persistent barriers, such as physical, social, and non-adaptive curricula, lead to inequitable access for persons with disabilities in higher education institutions. This reform is not only crucial to protect their rights but also to encourage their participation in broader social and economic development. This study aims to analyze the implementation of legal reform policies in creating inclusive access to higher education for persons with disabilities, as well as to identify the challenges still faced. The research employs a normative juridical method. The study finds that constitutional legal reform in Indonesia aims to ensure equal access to higher education for persons with disabilities through inclusive and non-discriminatory policies. Through regulations such as Law No. 8 of 2016 and Government Regulation No. 13 of 2020, the state is committed to providing disability-friendly facilities and adaptive curricula. This approach ensures that the rights of persons with disabilities are protected, allowing them to fully participate in higher education.
Comparative Mediation and Arbitration in Civil Dispute Resolution in Indonesia
Authors: Naisabur Nanang
Published: December 2024

The increasing number of civil disputes in Indonesia has created an urgency to find more effective dispute resolution methods to alleviate the burden on the judiciary. This study aims to compare the effectiveness of mediation and arbitration in dispute resolution, as regulated by Supreme Court Regulation No. 1 of 2016 and Law No. 30 of 1999. The normative juridical method was chosen to analyze the relevant legal framework to understand the strengths, weaknesses, and legal impacts of these two methods. This analysis also includes Roscoe Pound’s theory of legal efficiency and Satjipto Rahardjo’s progressive law approach, which emphasizes the importance of legal adaptability. Through this approach, the study is expected to provide comprehensive insights to assist legal practitioners, business actors, and the public in selecting the most appropriate method for efficiently resolving civil disputes. The research finds that mediation and arbitration have distinct advantages in resolving civil disputes in Indonesia; mediation is effective for maintaining relationships and cost-efficiency, while arbitration provides legal certainty with final decisions. Mediation, though fast, relies on formal agreements to be binding, whereas arbitration is more costly and does not permit appeals except under certain circumstances. Understanding these strengths and limitations helps stakeholders choose the most appropriate method to achieve substantive justice and efficiency in practice.

Authors: Yusran Gea Ali
Published: December 2024

Legal Politics of Legislation experiences problems both in terms of formation, political aspects, philosophical aspects, sociology and juridical aspects so that the formation of Legislation is greatly influenced by the tug-of-war of interests, both the political interests of the executive power, the political interests of the legislative power and the political interests of the judiciary. The legal implications related to the existence of Legal Politics problems in the formation of Legislation give birth to Legislation that is not of good quality so that the law enforcement process experiences a decline and is not legal certainty. Legislation as the basis for every implementation of government activities where Legislation is a part or subsystem of the legal system. The process of forming Legislation is part of the legal political process and plays a significant role in the development of national law. The formation of Legislation both in the planning, drafting, and discussion stages of the draft Legislation really needs the active role of the community. The problematic factors of legal politics in the formation of legislation include Legal Factors and Non-Legal Factors where legal factors include those that are contrary to the Constitution [1945 Constitution], contrary to the law, overlapping, contrary to legal norms and procedures that are contrary to Law No. 12 of 2011 concerning the Formation of Legislation, while non-legal factors include political factors, economic factors, social factors and cultural factors. Apart from legal and non-legal factors, the content of the legislation is also far from philosophical, sociological and juridical values.

Increasing operational efficiency of sectional pumps in kimberlite mines
Authors: Ovchinnikov N.P.
Published: December 2024

When an underground mine reaches the design capacity, the level of the mine water pollution can significantly increase as compared to the first years of its operation. For example, concentration of solid particles in water in a kimberlite mine drainage systems may increase more than two-fold. Increase in the content of suspended abrasive substances in the mine water negatively affects the life of water drainage equipment. One of the ways to improve the operational efficiency of sectional pumps in conditions of changing solid particles content in the mine water is to study the issue of adjusting the frequency of their overhaul. As a criterion of the optimum average time between overhauls of a sectional pump it is necessary to use its flow rate at the moment of overhaul, which corresponds to low specific operating costs for pumping mine water regardless of the size of water inflow and its pumping mode. Based on the results of the performed research a universal method of calculating the optimal average operating life time of a sectional pump before the overhaul is required. This methodology was developed for sectional pumps in kimberlite mines regardless of their model and their operating conditions. Calculations helped to establish that when the concentration of solid particles in the mine waters increases, a decrease in the average time between overhauls of sectional pump before overhaul becomes an economically feasible step.

Published: December 2024

The article addresses the issues of improving the design and implementation of process blasts of complex-structured rock masses in open-pit mining of solid minerals. The stages of adaptation are presented for the drilling and blasting technology in the new mining conditions in open pits of the Ural region, Siberia, Karelia and Kazakhstan. Systematization of the main factors that define the conditions for changing the drilling and blasting parameters is shown based on the data on in-situ physical and mechanical characteristics of rocks. The article shows transient processes in the classified form, which are used as the basis for the development of fundamental methodological principles for adapting the equipment and technology of drilling and blasting operations to the variable conditions of mining complex-structural deposits of solid minerals. A methodological approach is based on the established specific experimental data: the heterogeneity of the rock mass in terms of fracturing according to the roller-bit drilling data; the relationship between the detonation rate of emulsion explosives and the density and diameter of the explosive charge in its different ranges, the influence of the degree of attenuation of seismic blasting oscillations on the rate of displacement of the protected sections of the open pit walls at different directions of the explosive charge priming.

Utilizing advanced learning technologies, such as data analysis and artificial intelligence, teachers can identify student learning patterns, anticipate possible difficulties, and provide specific additional support. For example, by analyzing students' engagement with online learning platforms, teachers can tailor interventions to address individual learning needs, leading to more effective learning outcomes. Moreover, personalized learning in a digital environment goes beyond the delivery of content; it involves fostering 21st century skills such as critical thinking, communication, collaboration, innovation, and problem-solving. Research has shown that integrating technology into project-based learning activities can significantly enhance students' ability to develop these skills. By optimizing the potential of personalized learning approaches in a digital environment, educators can ensure that every student has an equal opportunity to develop the skills necessary to thrive in an ever-changing world.

Complex systems have a large dimension, consist of a large number of elements and connections between them. Networks are used to represent complex systems. Due to the high dimension of modern systems, researchers evaluate proposed solutions using generated networks. The high dimension of the system leads to problems in modeling and control. To solve these problems, methods for reducing the dimension of complex systems are required. Aggregation of the structural model of the system consists in combining elements of the system into subsystems and as a result dimension of the system and computational complexity are reduced. The subject matter of research is a software platform for evaluation of the effectiveness of structural model aggregation of complex systems. The goal of the work is to develop the software platform for evaluation of the effectiveness of structural model aggregation of complex systems. The relevance of the work lies in the fact that using the software platform it is possible to make the structural model aggregation of systems with a large number of elements and it is also possible to evaluate the effectiveness of structural model aggregation of the system. The following tasks were solved in the work: development of the software platform which consists of a system generator module, a system aggregation module, a maximum flow searching module and a statistical data processing module; structural model aggregation of the system using the software platform; evaluation of the effectiveness of structural model aggregation of the system using the software platform. As a result of the work the software platform was created, the structural model aggregation of the system was made and the effectiveness of structural model aggregation of the system using the software platform was evaluated. The studies allow us to conclude: using the software platform it is possible to generate a system, make the structural model aggregation of the system and solve the problem of the maximum flow searching; the software platform also allows to evaluate the effectiveness of structural model aggregation of the system; the value of the maximum flow is the same at two levels of the system, so in this case the structural model aggregation of the system is made while preserving the correctness of its parameters.

In this work, we investigated the possibility of describing changes in the dielectric parameters of snow at the initial stage of its melting at frequencies of 22.2, 37.5, 94, 150 and 300 GHz. Four models of mixing air and spherical ice and liquid water inclusions were used: “dry snow-water”, “ice-water-air”, “wet ice-air” and “dry snow-water”. The effective permittivity of melting snow was calculated using the following formulas: Maxwell Garnett formula for a two-component “dry snow-water” mixture, a three-phase mixture formula for the “ice-water-air” model, Maxwell Garnett and Wiener formulas for a two-component “ice-water” mixture and Maxwell Garnett formula for the “wet ice-air” mixture. It has been established that the “wet ice-air” (using Wiener formula to calculate the effective permittivity of wet ice) and “ice-water-air” models lead to almost identical results, while the results of the other two models differ significantly. On the other hand, all models showed that the extremum of the the imaginary part of the relative effective permittivity spectrum is located at a frequency of 94 GHz. The applicability of the above models for calculating the absorption coefficient of melting snow with spherical ice and water inclusions was verified by the results of corresponding calculations using the Mie theory for practically non-scattering ice particles 10 μm in size with volume density of 0.2; 0.4 and volume density of water 0.005, 0.01, 0.02 and 0.03. It has been established that in the frequency band 22...300 GHz the frequency dependence of the absorption coefficient of melting snow is satisfactorily described by the “wet ice-air” model when using the Maxwell Garnett formula twice.
Alianzas interétnicas en Cuyo a inicios del siglo XIX: el caso de las parcialidades mapuche-pehuenches y el gobierno sanmartiniano
Authors: Vilariño Martín Rodrigo
Published: December 2024

The following paper deals with the diplomatic relations established between the different Mapuche-Pehuenche partialities of southern Cuyo and the criollo government of Mendoza during the governorship of José de San Martín (1814 to 1816). Its objective is to deepen in the identification and reconstruction of the spaces, forms and motives of the interethnic diplomatic articulation in the San Martín period. The hypothesis is that the diplomatic links established between the two sides transcended the space of the parliaments, manifesting themselves in different instances and moments. For this purpose, the visits of different indigenous contingents to the city of Mendoza during these years will be analyzed, which will be reconstructed from different documents associated with these trips. The conclusion reached on this occasion is that these visits were an important part, as well as constitutive, of the interethnic diplomatic links, showing that these types of links were very complex and were not restricted only to the moments of the parliaments.
“Ya basta de fumigar, nuestra comunidad necesita sembrar”. Ambiente y salud en territorios indígenas de la provincia del Chaco
Authors: Castilla Malena Ines , Schimidt Mariana
Published: December 2024

The province of Chaco is one of the jurisdictions in northern Argentina which, at an early stage, incorporated changes in land use, large areas of deforested native forests and spraying with toxic products. At the regional level, this has led to the emergence of conflicts related to the levels of environmental contamination and the affectation of human and non-human health. This article describes and analyzes the conflicts surrounding the environmental and health effects derived from the use of agrochemicals in the province of Chaco. Specifically, it focuses on two localities belonging to the department of Libertador General San Martín (Pampa del Indio and Presidencia Roca), where fumigations affect the quality of life of indigenous peoples, small criollo farmers and peasants. Based on the analysis of diverse secondary sources together with interviews and field work, we approach the dispute of interests and meanings that has as protagonists the local inhabitants who, facing the imposition of an agribusiness model that excludes and sickens bodies and territories, resist and build alternatives of possible worlds, as is the case of the NO¨OXONEC experience of agroecological cotton production.
Historia de vida de las vasijas de La Toma (partido de Coronel Pringles)
Authors: Di Prado Violeta , Morosi Martín
Published: December 2024

En el registro arqueológico del área Interserrana bonaerense son infrecuentes los sitios con presencia de alfarería asignable fehacientemente a diferentes momentos del Holoceno tardío. Por este motivo, el reestudio del conjunto cerámico recuperado en el sitio multicomponente La Toma representa un oportunidad excepcional para evaluar, con herramientas teórico-metodológicas actualizadas, cambios y continuidades en los modos de hacer y decorar la alfarería en un mismo sitio. El estudio de láminas delgadas con microscopio de polarización permitió caracterizar diferentes modos de seleccionar y/o preparar las materias primas arcillosas en la cerámica más temprana (con predominio de litoclastos plutónicos) y la más tardía (con presencia de litoclastos sedimentarios); además se identificó la adición de tiesto molido en una pieza sin asignación cronológica. También se observaron diferencias en los modos de terminar las superficies; la cerámica temprana exhibe superficies más regulares y uniformes, y elementos decorativos realizados mediante surco rítmico, mientras que las caras de los contenedores tardíos se presentan más irregulares, con marcas de emparejado y alisado, sin decorar. La falta de estandarización y continuidad en los modos de hacer alfarería en La Toma permitió discutir procesos de interacción social y circulación de elecciones técnicas en escala areal y regional.
