Authors: Chang Ching-Wen , Farha Nicholas
Published: October 2024

In this researcher’s experience, online students very often ask questions about returned assignments, the answers to which are clearly articulated on Blackboard Learn (the learning management system (LMS) utilized at the site of this study). This raised the question of how much time and effort online students actually put into reading the assignment feedback provided in an online learning environment. The research question asked, “Is the instructor-provided assignment feedback on Blackboard of value to the learning experience?” This study examined college students’ perspectives concerning assignment feedback provided in their LMS. Participants included 71 undergraduate and graduate students in a program in the College of Education at a Midwest university. Descriptive statistics were used to analyze the responses to a 10-question researcher-developed survey. The findings indicated that the majority of online students find the assignment feedback provided by their instructors very valuable.

Purpose. To study the level of technical equipment of domestic agricultural production and investment and innovation support for its development in the context of European integration processes. Methods. Monographic, system analysis, abstract and logical. Results. Based on the results of an analytical study of the current state of the technical and technological base of domestic agro-industrial enterprises, the current model of agriculture in Ukraine is defined as industrial. In contrast, the leading European countries are characterised by post-industrial (innovative) agricultural production. Conclusions. The prospects of Ukraine‘s accession to the European space necessitate the development of a high-tech domestic agriculture based on the principles of sustainable development, which will ensure competitiveness and efficient agricultural business based on innovative production technologies and a modern machine and tractor fleet for their implementation. The development of a qualitatively new model of agriculture in Ukraine requires the development of a state strategy for updating the technical and technological base of agricultural production, which should outline the guidelines and priorities of domestic machine building for the agro-industrial complex. Keywords: agriculture, high-tech production, technical and technological base, sustainable development, competitiveness, innovation.

Authors: Lekule Thaddeus Aloyce , Mwiturubani Donald Anthony
Published: October 2024

This paper assessed the level of livelihood strategies practiced by Maasai pastoralists in Longido district, Tanzania. It focused on their resilience to climate variability. The main question that this sought to address was: How resilient are livelihood strategies to climate change and variability among the Maasai pastoralists in response to climate variability? This study employed the resilient theory by Holling and the DFID Livelihood Framework. The study used a mixed-method design, also known as a convergent parallel design. A multistage sampling technique was used to purposefully select wards, then villages, and then a simple random selection of the 373 households for the survey. This study purposively selected 21 key informants from traditional leaders, ward and village leaders, NGO officials, and livestock officers. While data gathered through interviews, observation and focus group discussions was analysed qualitatively. Data obtained through questionnaires was analysed quantitatively using IBM SPSS (version 20). The chi-square was used to test the association of the variables. Findings revealed that key strategies such as mobility, communal pooling, causal labour, livestock management, and others. Also, the role of education and sources of income were crucial in shaping resilience strategies. Household with more education were more likely to have reliable resilience strategies.  The main challenge faced by Maasai pastoralists in building climate resilience strategies is increased variability in climate, in the form of frequent drought and unreliable rainfall. This paper recommends more efforts to understand and support these communities by blending their traditional strategies with technical ones for sustainable livelihoods

Multi-Fractional Gradient Descent: A Novel Approach to Gradient Descent for Robust Linear Regression
Authors: Kalantari Robab , Rahimi Khashayar , Mezajin Saman Naderi
Published: October 2024

Authors:
This work introduces a novel gradient descent method by generalizing the fractional gradient descent (FGD) such that instead of the same fractional order for all variables, we assign different fractional orders to each variable depending on its characteristics and its relation to other variables. We name this method Multi-Fractional Gradient Descent (MFGD) and by using it in linear regression for minimizing loss function (residual sum of square) and apply it on four financial time series data and also tuning their hyperparameters, we can observe that unlike GD and FGD, MFGD is robust to multicollinearity in the data and also can detect the real information in it and obtain considerable lower error.
Hydrogen diffusion and hydrogen embrittlement in iron (steel)
Authors:   Institute of Catalysis and Inorganic Chemistry, Azerbaijan Republic, Asadov M.M.
Published: October 2024

This article examines the diffusion of hydrogen (H-diffusion) and the temperature dependences of the diffusion coefficient of hydrogen (DH) in the metal (M)-hydrogen system. The metal used was iron and low-alloy steel. Taking into account experimental data on hydrogen diffusion in the Fe-H and steel-H systems, the main diffusion parameters were calculated and compared. It is shown that the temperature dependences of the hydrogen diffusion coefficient in metal samples in a one-stage reaction under isothermal conditions are described by the Arrhenius equation. For some M-H systems, experimental data show a deviation of the diffusion coefficient from the ideal one calculated using the Arrhenius equation. This discrepancy can be eliminated using the statistical theory of absolute reaction rates. For the temperature range 25–1250 oС, the pre-exponential coefficient and activation energy of hydrogen diffusion in a body-centered cubic (bcc) lattice of iron (α–Fe) were calculated using the Arrhenius equation. These parameters make it possible to describe the dependence of the rate of hydrogen diffusion in a metal on temperature and to predict the behavior of hydrogen diffusion when changing the conditions of the kinetic process (concentration of substances, pressure, structure, composition, etc.). Tabular values of the calculated pre-exponential factor and activation energy of hydrogen diffusion in previously studied iron-based samples are presented. The temperature dependences of the hydrogen diffusion coefficient in a lattice of iron α–Fe can be divided into low-temperature and high-temperature regions. The calculated diffusion parameters of hydrogen in the metal lattice for the low-temperature 25– 800 oC and high-temperature 800–1250 oC regions differ markedly from each other. In addition, these calculated values are significantly influenced by the structure and composition of the metal. We also studied the diffusion of hydrogen in α-iron using ab initio density functional calculations. Molecular dynamics calculations using transition state theory were used. The calculated diffusion coefficient of hydrogen in α-Fe is consistent with previously obtained experimental data. Hydrogen embrittlement (HE) is considered using internal pressure, hydrogen enhanced localized plasticity (HELP) and hydrogen enhanced decohesion embrittlement (HEDE) theories.
On the transition of liquid dispersion states and their physical-thermodynamic nature in the development of gas-condensate reservoirs in depletion mode

While the depletion regime for gas-condensate fields may be more cost-effective, it often results in the loss of hydrocarbon condensate, which is economically more valuable than gas, and leads to the inefficient exploitation of the field in terms of condensate production. Therefore, the development of effective exploitation systems for such fields is essential. Effective exploitation of gas-condensate fields involves achieving maximum hydrocarbon condensate production in addition to maximum gas production. From this aspect, managing the condensate factor of reservoir system during the depletion regime is a critical issue. The article experimentally and theoretically investigates the phase transitions or mutual dispersion occurrences between hydrocarbon liquid and gas mixtures that occur with a decrease in pressure at reservoir temperature during the natural depletion of gas-condensate fields. During the exploitation of gas-condensate fields, it has been observed that even at pressures higher than retrograde condensation pressure, the hydrocarbon system undergoes complex phase transitions, resulting in distinct transition points due to the mutual dispersion of hydrocarbon liquid and gas. Additionally, pVT studies conducted in the laboratory have made it possible to determine the transition points of the reservoir fluid in the “liquid in gas” and vice versa dispersion states. The research has demonstrated that dependance of gas condensate factor on pressure under given isothermal natural conditions more clearly reflects the retrograde and maximum condensation, also dispersion points of the liquid components. It was found that proportionality coefficient between condensate ratio and pressure of gas-condensate system is unique for each production facility under isothermal conditions and characterizes the stability of fluid’s dispersion state. The importance of considering such transition points when designing gas-condensate field development projects has been highlighted.

De onbemindheid der wiskunde – Die Unbeliebtheit (von Teilen) der Mathematik
Authors: Gropp Harald
Published: October 2024

Im folgenden Beitrag wird über einen Vortrag aus dem Jahre 1926 berichtet, also vor fast 100 Jahren, und auch über seine mögliche Relevanz für didaktische und pädagogische Fragestellungen. Dieser Vortrag von Johan Antonij Barrau (1873–1953) war dessen Rektoratsrede an der Rijksuniversiteit in Groningen mit dem Titel De onbemindheid der wiskunde. Barrau legt dar, dass viele Teile der Mathematik beim breiten Publikum eher unbeliebt sind, wohingegen gewisse Teile der Geometrie wie auch die Kombinatorik, endliche Geometrie oder die sogenannte Unterhaltungsmathematik beliebt sind und sich deshalb gut für „onderwijs“ eignen. Nach einem Aufenthalt in Niederländisch-Indien zwischen 1891 und 1898 war Barrau Lehrer und studierte in Amsterdam. Er schrieb seine „proefschrift“ (Dissertation) über Bijdragen tot de theorie der configuraties (Beiträge zur Theorie der Konfigurationen) im Jahre 1907. 1909 wurde er zum Professor berufen, zunächst in Delft und später in Groningen. 1928 erhielt er den Lehrstuhl für „meetkunde“ (Geometrie) in Utrecht, den er bis 1943 bzw. 1946 innehatte.

Accounts receivable management is crucial for companies, especially those selling products on credit. Effective management of receivables ensures that credit returns are handled efficiently, leading to increased company revenue. In this final project, it is noted that receivables management at Perumda BPR Bank Kota Bogor is carried out both manually and through a system. Despite this, problematic and non-performing loans still occur. These problematic and non-performing loans arise due to internal factors within the bank, such as errors in credit analysis and inadequate data verification. Additionally, external factors from the debtors include a decrease in the debtor's payment ability, business losses, reassignment or termination of the debtor, and the misuse of credit by the debtor for purposes other than intended. The resolution of problematic and non-performing loans has been addressed through rescheduling, reconditioning, restructuring, collateral takeovers, and write-offs. Perumda BPR Bank Kota Bogor also undertakes measures to minimize the occurrence of problematic and non-performing loans in the future by conducting detailed and accurate credit analysis, regular monitoring, and maintaining good relationships with debtors.

Implications of Financial Distress on Tertiary Education in Nigeria
Authors: Oyeleye Bolanle Oluwatosin , Bamikole Oloruntoba Ige , Ibidapo Tawio Olusola
Published: October 2024

The study examined the implications of financial distress on tertiary Education Nigeria. The financial distress in tertiary institutions in Nigeria today can be attributed to poor management and leadership problems. This has tremendously affected the operations of higher institutions in Nigeria. The university system requires a lot of funds for effective administration to be able to achieve its goals. The inability of the government to stick to the UNESCO 26% of national budget for education has seriously affected the management of Nigerian universities. Most of Nigerian tertiary institutions today face a lot of problems due to financial distress. As many of them find it difficult to pay workers’ salaries, provide adequate infrastructure and teaching equipment. The causes and implications of financial distress on tertiary Education were examined. It was recommended that both federal and state governments need to collaborate more with the private sector to explore opportunities for raising non-traditional funds and participation in education financing. Also, government should stop the habit of diverting the funds meant for tertiary education projects to other sectors. In addition, funds disbursed for projects and programmes should be adequately supervised, monitored and evaluated to achieve effective implementation.

El plan de desarrollo local implica una fase de acuerdos entre las fuerzas que interactúan dentro de una localidad para proponer un proyecto. El objetivo principal de esta investigación fue crear un plan de desarrollo local para los pequeños productores de cacao, promoviendo el desarrollo sostenible en el recinto María Rosa del cantón Quinsaloma. La metodología utilizada fue un diagnóstico de campo, aplicando enfoques inductivo, deductivo y analítico. Se realizó una encuesta de 27 ítems a una muestra de 145 productores de cacao. Los resultados destacaron varios desafíos importantes, como la falta de apoyo gubernamental por parte de instituciones agrícolas, la carencia de servicios básicos y las deficientes vías de acceso a las fincas. Además, la dependencia de intermediarios para la comercialización del cacao seco y en baba fue identificada como un obstáculo significativo. La propuesta de desarrollo local se centra en la formación de una asociación de productores de cacao, donde se tracen proyectos y estrategias para fortalecer la producción y mejorar los procesos de comercialización, generando así mejores ingresos y una mejor calidad de vida para los productores.

Published: October 2024

El presente proyecto investigativo tiene como principal objetivo diseñar una propuesta pedagógica desde la percepción que poseen los docentes en el enfoque de Koch y Girard de la resolución de conflictos en los estudiantes universitarios del primer semestre de Psicología de la facultad de salud de la Universidad de Pamplona. Esta investigación, a través de dicho enfoque, ha demostrado ser efectiva en la resolución de conflictos en diferentes niveles y contextos, promoviendo la transformación de relaciones conflictivas hacia relaciones basadas en la confianza, el respeto mutuo y la cooperación, se ha aplicado con éxito en procesos de reconciliación y construcción de paz, contribuyendo a la superación de la violencia y la construcción de una cultura de paz y convivencia pacífica. En conclusión, el enfoque de Koch y Girard ha demostrado ser una herramienta efectiva para la resolución de conflictos en Colombia, promoviendo la transformación pacífica de relaciones y contribuyendo a la construcción de una sociedad más justa, equitativa y pacífica. Su aplicación en diferentes contextos ha permitido avanzar hacia la construcción de una cultura de paz y convivencia pacífica en el país. La investigación fue encaminada bajo un modelo cualitativo, además de adoptar un diseño de tipo Investigación Acción (IA), el cual permite activamente la participación consciente de los informantes clave. La población seleccionada estaba formada por 5 estudiantes del I semestre del Programa de psicología de la Universidad de Pamplona, distribuidos en dos mujeres y 3 hombres con edades comprendidas entre 16 y 21 años, quienes ostentan un rendimiento social excelente, aceptable o deficiente. Cabe aclarar que, para esta investigación, se les requirió únicamente para suministrar información por medio de técnicas como la entrevista, talleres, juegos de roles, charlas educativas y observación. Con el fin de recolectar la información, se implementaron instrumentos como formularios de preguntas y diarios de campo. La validez de dichos instrumentos está comprobada por expertos.En este orden de ideas, según Burton y Sandole (1986), los propósitos significan la terminación del conflicto a través de métodos analíticos que se dirigen a la raíz del problema. Resolución de conflictos interculturales, como opuesto a una mera gestión o ajuste, se orienta al resultado que, de acuerdo con las partes implicadas, es una solución permanente del problema. Se entiende que la resolución de conflictos busca abordar las fuentes subyacentes de los problemas, con el objetivo de prevenir su recurrencia y contribuir a la eliminación de sus causas.

Spatial Negative Influence of Cairo Mega Movement corridors on adjacent Local Areas Land Uses and Movement
Authors: Youssef Mohamed
Published: October 2024

The research is focused on discussing the importance of transportation in metropolitan areas and analyzing the positive and negative spatial impacts of the major movement corridors in Greater Cairo on the surrounding local areas. It aims to highlight the regional benefits of these corridors while also addressing the spatial challenges faced by the local areas. The study emphasizes the significance of movement circulation for pedestrians and vehicles in the urban functionality of local movement, serving as a connection between land uses and daily activities. While the mega movement corridors have significantly improved access between Greater Cairo's main districts, they have also introduced challenges at the local level. The research examines the impact of the Ain Shams corridor as an example of a new movement corridor introduced by the government in the last 5 years, in two major areas, and additionally, identifies the resulting challenges in land uses and movement circulation in these areas. The findings underscore the importance of segregating movement circulation between the regional and local levels to enhance accessibility for pedestrians and vehicles in local areas. Furthermore, the study reinforces the importance of comprehensive measures to enhance the efficiency of the corridor. Implementing solutions such as dedicated service roads, improved parking infrastructure, and optimized traffic management strategies can play a pivotal role in mitigating congestion and addressing the specific needs of local traffic. By addressing these challenges, the corridor can achieve improved functionality, accommodate the diverse traffic demands, and enhance the overall transportation experience for commuters and urban activities.

Time-resolved spectral analysis of the prompt gamma-ray emission was conducted utilizing the Bayesian block method to determine statistically optimal time bins. Based on the Bayesian Information Criterion, the data generally favor the Band+blackbody (BB) model. We speculate that the main Band component comes from the Blandford–Znajek mechanism, while the additional BB component comes from the neutrino annihilation process. The BB component becomes significant for a low-spin, high-accretion-rate black hole central engine, as evidenced by our model comparison with the data. The afterglow light curve exhibits typical power-law decay, and its behavior can be explained by the collision between the ejecta and the constant interstellar medium.

TESS Asteroseismic Masses and Radii of Red Giants with (and without) Planets
Authors: Pope Myles , Carlberg Joleen K. , Valenti Jeff , Branton Doug
Published: October 2024

We present a study of asteroseismically derived surface gravities, masses, and radii of a sample of red giant stars both with and without confirmed planetary companions using TESS photometric light curves. These red giants were drawn from radial velocity surveys, and their reported properties in the literature rely on more traditional methods using spectroscopy and isochrone fitting. Our asteroseismically derived surface gravities achieved a precision of ∼0.01 dex; however, they were on average ∼0.1 dex smaller than the literature. The systematic larger gravities of the literature could plausibly present as a systematic overestimation of stellar masses, which would in turn lead to overestimated planetary masses of the companions. We find that the fractional discrepancies between our asteroseismically determined parameters and those previously found are typically larger for stellar radii (∼10% discrepancy) than for stellar masses (<5% discrepancy). However, no evidence of a systematic difference between methods was found for either fundamental parameter. Two stars, HD 100065 and HD 18742, showed significant disagreement with the literature in both mass and radii. We explore the impacts of updated stellar properties on inferred planetary properties and caution that red giant radii may be more poorly constrained than uncertainties suggest.
XMM-Newton Perspective of the Unique Magnetic Binary-ϵ Lupi

The ϵ Lupi A (HD 136504) system stands out among magnetic massive binaries as the only short-period binary system in which both components have detectable magnetic fields. The proximity of the magnetospheres of the components leads to magnetospheric interactions, which are revealed as periodic pulses in the radio light curve of this system. In this work, we aim to investigate the magnetospheric interaction phenomenon in the X-ray domain. We observed this system with the XMM-Newton telescope, covering its orbital period. We observe variable X-ray emission with maximum flux near periastron, showing similarity with radio observations. The X-ray spectra show significantly elevated hard X-ray flux during periastron. We attribute the soft X-ray emission to individual magnetospheres, while the hard X-ray emission is explained by magnetospheric interaction, particularly due to magnetic reconnection. However, unlike in the radio, we do not find any significant short-term X-ray bursts. This exotic system may be an ideal target to study magnetospheric interactions in close binaries with organized magnetospheres.
Nonthermal Signatures of Radiative Supernova Remnants

The end of supernova remnant (SNR) evolution is characterized by a so-called “radiative” stage, in which efficient cooling of the hot bubble inside the forward shock slows expansion, leading to eventual shock breakup. Understanding SNR evolution at this stage is vital for predicting feedback in galaxies, since SNRs are expected to deposit their energy and momentum into the interstellar medium at the ends of their lives. A key prediction of SNR evolutionary models is the formation at the onset of the radiative stage of a cold, dense shell behind the forward shock. However, searches for these shells via their neutral hydrogen emission have had limited success. We instead introduce an independent observational signal of shell formation arising from the interaction between nonthermal particles accelerated by the SNR forward shock (cosmic rays) and the dense shell. Using a semi-analytic model of particle acceleration based on state-of-the-art simulations coupled with a high-resolution hydrodynamic model of SNR evolution, we predict the nonthermal emission that arises from this interaction. We demonstrate that the onset of the radiative stage leads to nonthermal signatures from radio to gamma rays, including radio and gamma-ray brightening by nearly 2 orders of magnitude. Such a signature may be detectable with current instruments, and will be resolvable with the next generation of gamma-ray telescopes (namely, the Cherenkov Telescope Array).
Mitochondrial evidence on the phylogenetic position of the Southeast Asian catfish genus Encheloclarias Myers, 1937 (Actinopterygii: Siluriformes: Clariidae): Evolutionary and conservation implications

Published: October 2024

The phylogenetic position of the Southeast Asian catfish genus Encheloclarias Myers, 1937 within the family Clariidae is inferred herein using three mitochondrial nucleotide markers: cytochrome b, cytochrome oxidase subunit I, and 16S rRNA genes. We found that Encheloclarias is neither exclusively related to the African taxa having extended neural spines posterior to the dorsal fin (Encheloclarias shares with some of these taxa the presence of an adipose fin, as opposed to absent in all other clariid taxa) nor to the Asian species of the genus Clarias Scopoli, 1777. Encheloclarias is hypothesized to be the sister group of all other clariids, except Horaglanis Menon, 1951. The inferred position of Encheloclarias confirms that the adipose fin in this genus has an evolutionary origin independent to that of the adipose fin found in some African clariids. Encheloclarias is not only ecologically remarkable, being adapted to acidic peat swamps in Southeast Asia, but it is also an ancient lineage sheltering in these habitats. However, the precise timing of the colonization of peat swamps by Encheloclarias remains to be investigated. The phylogenetic position of Encheloclarias further underscores the importance of studying and protecting the remaining peat swamp habitats in Southeast Asia and their distinctive aquatic fauna.
Intranasal nanocrystals of tadalafil: in vitro characterisation and in vivo pharmacokinetic study

Published: October 2024

Tadalafil (TDA) is a class II drug of the biopharmaceuticals classification system (BCS), with limited aqueous solubility and high permeability. This study aims to improve the bioavailability of poorly soluble tadalafil by developing intranasal nanocrystals (NCs) of TDA. TDANCs that were stabilised by polyvinyl alcohol (PVA) had the lowest size and the best solubility. F11 had a 196 nm in size with PDI and zeta potential of 0.21 and -11.20, respectively, which shows 5.5 and 1.6-fold higher in solubility (9.37 ± 0.36 μg/mL) and dissolution (50.11 ± 1.69%) than pure tadalafil, respectively. An in vivo animal study demonstrated that the maximum plasma concentration (Cmax) and total area under the curve (AUC0∞) achieved in the TDANCs group were 352.77 ± 35.17 ng/mL and 3377 ± 558 ng.h/mL, respectively, and were significantly higher than the pure TDA group after intranasal administration. In conclusion, TDANCs were successfully prepared by the sonoprecipitation technique, with significant enhancement in in vitro and in vivo properties. Therefore, intranasal administration of TDA nanocrystals was a good model for the treatment of erectile dysfunction.
Nature et éducation selon Locke et Condillac
Authors: Pierrès Raphaёl
Published: October 2024

Cet article interroge la relation entre nature et éducation au moyen d’une confrontation entre les Quelques pensées sur l’éducation de Locke et le Cours d’études de Condillac. Nous analysons d’abord le statut chez Locke du fond naturel, en lien à sa manière de défendre une méthode pédagogique naturelle. Est-il légitime de viser une éducation naturelle ou faut-il assumer une rupture entre éducation et nature ? Nous questionnons alors le rapport entre nature et coutume dans le Cours d’études de Condillac, et la fonction des signes naturels dans les philosophies de l’expérience.
