Modern Trends in e-learning Tools and Technologies in Education with the Use of Blackboard
Authors: Asim Researcher. Tayyiba Asim Muhammad , Naeem Researcher. Farah , Yousaf Researcher. Aimen 
Published: August 2023

The 21st century society requires a flexible learning environment. The learning environment should be capable of adapting to teaching goals, learning objectives, students' capabilities, students' preference for information and the latest communication technology and services. In the past few decades, several e-learning tools have been developed and used in educational systems. These e-learning tools have turned out to be a great resource in providing education or training to students with diverse cultural backgrounds and educational levels. However, there remains a research gap in understanding the modern e-learning tools and their ability to reach educational goals. Failure to understand the actual capabilities of e-learning or expecting too much from e-learning tools and technology can result in a failure to educate or train students effectively.
The purpose of this research paper is to review the trends and tools used for e-learning, with a focus on the capabilities of Blackboard in providing effective education. It will discuss the positives and negatives of using e-learning to educate students. This experimental study covers Blackboard as an e-learning tool aiming to investigate its usefulness and ease of use as reported by student users. It will also study the possibility of using Blackboard to create and support a collaborative learning environment.
The impact of using Blackboard as a language teaching and learning tool in Gulf Universities has gained attention in the recent years due to the impact it can carry on the achievement and performance of learning a foreign language. The research analysis provides us with a view of the current and future tendencies of e-learning tools, specifically Blackboard, and helps provide substantive understanding of e-learning tools used in the classroom. Results of the study indicated that the students found Blackboard to be a useful tool for obtaining class materials, submitting homework and assignments, taking quizzes and tests, and preparing a project. Additionally, its accessibility and adaptability proved it to be helpful, easy-to-use, and effective in increasing productivity. The study shows that students' experience with the tool has resulted in a perceived ease of use and perceived usefulness.
Similarly, Blackboard was found to be effective in reaching the teaching goals set by an institute. However, Blackboard's lack of a social network results in the lack of a collaborative environment for students and teachers alike. E-learning is also dependent on cloud computing to synch information among all electronic devices to provide training and professional development opportunities.
Prática de produção de texto: da obra Minhas férias, pula uma linha, parágrafo aos gêneros multimodais
Authors: Da Silva Juliani Cristina , Valerio Claudia Lúcia Landgraf 
Published: August 2023

Este trabalho investiga a temática gêneros textuais no ensino de língua portuguesa, mais especificamente, como os gêneros textuais eram trabalhados na década de 80, a partir das orientações dos Parâmetros Curriculares Nacionais (Brasil,1998), qual era a estrutura desses textos, e o que mudou com a chegada da Base Nacional Comum Curricular (Brasil, 2017), no processo de ensino e aprendizagem da língua portuguesa do ensino básico e, principalmente, na produção textual. Com base no livro: Minhas férias, pula uma linha, parágrafo (Gribel, 2009), analisamos como eram escritos os textos, quais eram as suas bases e quais eram os princípios utilizados para a correção deles.Com o objetivo de analisar a mudança que ocorreu ao longo das últimas décadas, assim como quais foram as orientações dos documentos oficiais para a prática docente em relação a esse assunto. Por fim, considerando os gêneros textuais como meios de comunicação e interação, percebe-se que seu uso em aulas de língua portuguesa é essencial no processo de ensino aprendizagem. Por serem os gêneros textuais, artefatos da comunicação, eles estão em constante mudança, ou seja, a cada dia que passa surgem novos gêneros. Daí a importância de uma recontextualização e um planejamento adequado, para que os docentes trabalhem os gêneros de forma atual e adaptável à realidade do aluno.
Thiamine: overview of history of discovery, mechanism of action, role and deficiency
Authors: Napiórkowska Ewa 
Published: August 2023

Thiamine is the first water-soluble vitamin to be discovered that acts as a cofactor of several important enzymes. Vitamin B­1 plays an essential role in obtaining energy in carbohydrates metabolism and substrates production which are further used as neurotransmitters, nucleic acids, and coenzymes. The aim of this work was to give a summary of various aspects related to thiamine including a rich history of the discovery, synthesis, role in human organism, mechanism of action and also the consequences of its insufficient intake leading to beriberi disease. The study takes into consideration pharmaceutical aspects like main sources of vitamin B­­­1, its absorption, nutrient recommendations, interaction with drugs and the variety of formulations available in treating its deficiency. Understanding the role of vitamin B1 in cellular metabolism shows its significance in maintaining health and emphasizes the importance of ensuring adequate dietary intake to maintain the proper functioning of the nervous and cardiovascular systems. Although thiamine deficiency is less common in developed countries, it can be still observed due to poor diet intake, alcoholism, and certain medical conditions which reduce absorption, e.g. celiac disease. Overall, all mentioned aspects make the problem of its deficiency still present and important. Performing an overview of various aspects related to thiamine deficiency can help to properly diagnose or even to prevent an insufficient intake of vitamin B1 among patients with specific medical conditions.

Existence and multiplicity for radially symmetric solutions to Hamilton-Jacobi-Bellman equations
Authors: Li Xiaoyan , Yang Bian-Xia 
Published: August 2023

This article concerns the existence and multiplicity of radially symmetricnodal solutions to the nonlinear equation $$\displaylines{ -\mathcal{M}_\mathcal{C}^{\pm}(D^2u)=\mu f(u) \quad \text{in } \mathcal{B},\cru=0 \quad \text{on } \partial\mathcal{B}, }$$ where \(\mathcal{M}_\mathcal{C}^{\pm}\) are general Hamilton-Jacobi-Bellman operators, (\mu\) is a real parameter and \(\mathcal{B}\) is the unit ball. By using bifurcation theory, we determine the range of parameter \(\mu\) in which the above problem has one or multiple nodal solutions according to the behavior of \(f\) at 0 and infinity, and whether \(f\) satisfies the signum condition \(f(s)s>0 \) for \(s\neq 0\) or not.

Energy-dependent Hamiltonian in a nuclear optical model
Authors: Huu-Tai Pierre Chau , Ducomet Bernard 
Published: August 2023

We study the spectral properties of a 1D model of optical potential introduced by Morillon and Romain [21] in the context of nuclear reactions. We can localize the discrete spectrum and estimate the number of eigenvalues. We also study the continuous spectrum with possibly embedded spectral singularities and give an expansion formula for an arbitrary function on a set of generalized eigenfunctions. We briefly study the resonances of a related model.

Análisis cinético de la biodegradabilidad anaerobia de la cachaza con pretratamiento termoalcalino en la producción de metano
Authors: Ríos Obregón Jorge Manuel , Bernal Gutiérrez Regla , López González Lisbet , Jiménez Hernández Janet , Morell Pérez Leobel 
Published: August 2023

La cachaza, es el principal residuo del proceso de fabricación de azúcar y su elevado volumen se ha convertido en un importante contaminante del entorno. El pretratamiento termoalcalino constituye un método eficaz dada la naturaleza de la cachaza y permite una mayor producción de metano en condiciones anaeróbicas. En esta investigación se realiza un análisis cinético de la biodegradabilidad anaeróbica de la cachaza previamente tratada, a diferentes tiempos, con hidróxido de sodio NaOH, como agente químico y temperatura de 75 0C. Para el estudio se tomó cachaza proveniente el ingenio azucarero “Melanio Hernández”, provincia de Sancti Spíritus; Cuba y su caracterización físico-química se realizó mediante el análisis de sólidos totales (ST), sólidos volátiles (SV) y Ph. Se determinaron los parámetros cinéticos por digestión anaeróbica en condiciones mesófilicas (37± 1 ˚C) se obtiene que los modelos cinéticos que describieron el mejor comportamiento de la digestión anaerobia fueron el de Hill y Chapman con un alto coeficiente de correlación. Los menores rendimientos alcanzados comparados con la literatura para otros sustratos pueden estar afectados por compuestos no deseados que pudieran solubilizarse y afectar el proceso de digestión anaerobia. La oxidación de la lignina a compuestos fenólicos solubles es un riesgo por su posible efecto inhibitorio sobre el proceso de digestión anaerobia. Entre ellos, se encuentran ácidos, aldehídos y alcoholes aromáticos. También las reacciones de Maillard pueden ocurrir bajo condiciones termo-alcalinas con sustratos que contienen proteínas y carbohidratos, como es el caso de estudio, con la formación de compuestos recalcitrantes como son las melanoidinas.

Authors: Ramunaidu P. V. S. , Sekhar D. , Sowjanya A. , Srinivas D. , Pavankumar P. , Babu P. 
Published: August 2023

Aims: A field experiment was conducted to assess the impact of various irrigation schedules and wheat varieties on yield characteristics and yield of wheat in Andhra Pradesh's high altitude and tribal area (HAT) zone.
Study Design: Split-plot design was used to conduct the research experiment.
Place and Duration of Study: Regional Agricultural Research Station, Chintapalle, Visakhapatnam, ANGRAU, Andhra Pradesh. The study was conducted during Rabi season 2021-22.
Methodology: Split-plot design was used to conduct the experiment in which as main plots, there were three irrigation schedules—irrigation at CRI, maximum tillering, jointing, flowering, and milking stages (M1); irrigation at CRI, flowering, and milking stages (M2); and irrigation at CRI and milking stages (M3)—and four varieties—DBW-252(V1), HI-1544(V2), HI-8759(V3), and HI-8713(V4)—as subplots. The parameters of Spike length, Spike weight, number of productive tillers m-2, number of grains spike-1, number of filled grains spike-1, 1000 grain weight, grain yield, straw yield, biological yield, and harvest index were found to be superior with five irrigations scheduled at CRI, maximum tillering, jointing, flowering, and milking stages. Among the varieties, HI-8759 recorded the highest values, which were comparable to HI-8713.
Results: Spike length, spike weight, no. of productive tillers m-2, no. of grains spike-1, no. of filled grains spike-1, 1000 grain weight found superior with five irrigations schedules. The highest values among the variations were achieved by HI-8759 and were comparable to HI-8713.The five irrigation schedule resulted in higher grain and straw yields. Despite the fact that there was a reduced grain yield with two irrigations, the straw yield was statistically equal with three irrigations. With five irrigations, the harvest index (%) was much higher, while with two irrigations, it was significantly lower. However, HI-8759 had a much greater grain and straw production than the other cultivars. The straw yield remained at HI-8713 levels. The HI-8759's harvest index outperformed all other kinds by a wide margin. With HI-1544, the lowest grain and straw yields were noted.
Conclusion: Wheat yield was dramatically increased by five different irrigation regimens applied at various phenological phases. The maximum yield was recorded by variety HI-8759, which was comparable to variety HI-8713 in terms of biological and straw yields.

Published: January 2025

AbstractOne‐step adsorptive purification of ethylene (C2H4) from ternary mixture comprising of acetylene (C2H2), ethylene (C2H4) and carbon dioxide (CO2) is a great challenge in the chemical industry. Herein, a microporous metal–organic framework (FJI‐H38) has been reported, which possesses high‐density electronegative O/N binding sites and appropriate pore size. Notably, at 0.01 bar and 298 K FJI‐H38 shows excellent trapping capability for C2H2 (1.64 mmol/g) and CO2 (2.33 mmol/g), while the uptake of C2H4 is only 0.41 mmol/g, which endows FJI‐H38 high C2H2/C2H4 and top‐level CO2/C2H4 selectivity simultaneously. Polymer‐grade C2H4 (≥99.95 %) with record‐high productivity can be successfully obtained from ternary C2H2/CO2/C2H4 mixture in one step under various conditions. Even at 318 K, the separation performance has no obvious decrease. Such excellent separation performance is due to the adaptive recognition of C2H2 and CO2 by FJI‐H38 through the synergistic effect of appropriate pore size and the match of electrostatic potentials, where C2H2 and CO2 can be stabilized by the O/N and aromatic ring sites.
