Published: September 2023

This study aimed to investigate the thermal behavior of water flows in a
solar collector equipped with zig-zag tubes. To achieve this, a numerical
simulation using CFD was conducted, which is a powerful tool for analyzing
fluid-flow and heat transfer. The simulation employed the finite volume
method to discretize the fluid domain and the SIMPLE algorithm to solve the
pressure-velocity coupling. The simulation results indicated that the shape
of the tubes significantly influenced the flow behavior and overall
performance of the solar collector. Specifically, the temperature profiles
at various times of the day showed that zig-zag-shaped tubes enhanced the
heat transfer coefficient, resulting in higher temperatures within the
collector. Moreover, the zig-zag design increased the residence time of the
fluid inside the collector, further improving its overall efficiency. These
findings highlight the potential of utilizing zig-zag-shaped tubes to
optimize the performance of solar water heating systems, which could have
important implications for renewable energy applications.

Published: September 2023

In this study, the coldest days of 2022 in the Djelfa region, Algeria, were
determined using astronomical and climatic data. The timing of sunrise,
sunset, and duration of sunlight, as well as changes in solar radiation
intensity and air temperature, were analyzed. By converting solar radiation
into heat and solving differential equations, the study examined water exit
temperature, thermal energy, and total yield as outputs of a renewable
energy converter. The effect of different glass coverings on these outputs
was also investigated. The coldest day in 2022 was found to be the first day
of January, with nine hours and 43 minutes of sunlight, a maximum solar
radiation intensity of 670.34 MW/m?, and a maximum air temperature of 16.9?C. The outputs of the solar center followed a parabolic pattern for the
first two parameters and increased over time for the remaining outputs,
regardless of the glass type. However, using glass with a high emission
coefficient, such as clear monochromatic glass, resulted in the highest
values for the outputs: 52.57?C, 7.5 kW, 162 MW, and 70.62%. By
understanding solar energy conversion and thermal behavior, the study
contributes to energy-efficient designs and renewable integration, aiding
in sustainable urban development. Findings can inform decision-makers in
optimizing material selection, promoting resilient infrastructure, and
advancing sustainable practices for a low-carbon future.
Investigation of the effect of pre-deformation shape on cold forming properties in the product material in fastener production
Authors: Mermer Murat , Ovali Ismail
Published: September 2023

Due to product features such as production quality and high surface quality,
cold forging and cold extrusion methods are widely used in the production of
fasteners. Extrudability plays a key role during the process and is
affected by many process parameters. Die shape characteristics directly
affect cold deformation. In particular, deformation hardening is influenced
by the shape characteristics. The cold extrusion process also significantly
affects mechanical properties. In this study, the effect of die shape
characteristics on the extrudability of 20MnB4 (EN 10263-4) low carbon steel
was investigated. Additionally, finite element analysis was conducted to
optimize extrudability. Radiuses, angular, and radius-angular die shapes
were used in the experimental and finite element analysis. The SIMUFACT
FORMING software was used for finite element analysis. Both experimental
and finite element analysis results showed that die shape significantly
affects the extrudability of steels. Extrudability of steels can be
optimized with the die shape. The highest homogeneous metal flow was
obtained in the sample obtained from the radius-angular die shape. Samples
with an angular die shape showed the lowest extrudability feature. Hardness
and finite element analysis results were consistent.
Mechanical properties research of carbon fibre composites incorporating nanoclay and graphene
Authors: Ongun Alemdar
Published: September 2023

Study purpose is to determine the interactions between the widely-used
graphene and nanoclay on carbon fiber composite materials. They are produced
using the vacuum infusion method by reinforcing the nanoclay and graphene,
which have a montmorillonite structure organized at various ratios via
homogenizer, into the resin that is to be applied to carbon fiber layers.
Eczac?ba?? EsanNANO 1-140 was used as nanoclay, and GRAFEN NG5 of the
Nanografi Co. Ltd. was used as graphene. The graphene ratio was kept
constant by taking reference from antecedent studies. Tensile test was
applied to the produced samples. Graphene in the resin is expected to
increase the saturation in the layers and improve mechanical properties.
After nanoclay ratio exceeds a certain limit, it acts negatively rather than
positively in the tensile test, their cracked roads are then rendered easier
to traverse by them combining. This is why there is a certain bell-shaped
curve in the strain values measured in samples. The result that gives the
optimum values is sought after. Additionally, there are studies previously
conducted with polymer matrix composite, from which samples that could reach
to certain strains or to higher yield stress values in certain intervals are
obtained. By increasing the strength and toughness of the graphene and
nanoclay resin, they gain more rigidity, which raises an expectation of
increment to be observed in the yield and tensile strengths.

Published: September 2023

Numerical simulations, based on relatively complex physical models developed
for CFD, can accurately predict engine-out responses, but they require huge
memory space and/or computation time. In terms of resources and computer
time, artificial intelligence methodologies are more cost-effective. In this
work, we used an ANN to predict the performance and exhaust emissions of a
single-cylinder Diesel engine running on fossil diesel, biodiesel, and
their blends under various speed and load regimes. To perform the modeling,
we employed multilayer perceptrons and a back-propagation gradient algorithm
with momentum to train the network weights. The modification of the network
weights was done using the second-order method of Levenberg-Marquardt, and
the technique of early termination was utilized to avoid overtraining the
model. The study involved using 70% of the complete experimental data to
train the neural network, allocating 15% for network validation, and
reserving the remaining 15% to evaluate the trained network effectiveness.
The ANN model that was created demonstrated remarkable accuracy in
predicting both engine performance and emissions. This is evident from the
strong correlation coefficients observed, which ranged from 0.987 to 0.999,
as well as the low mean squared errors ranging from 7.44?10-4 to 2.49?10-3.
Bridging the Digital Skills Gap in Accounting: The Process Mining Audit Professional Curriculum and Badge
Authors: Emett Scott A. , Eulerich Marc , Lovejoy Katherine , Summers Scott L. , Wood David A.
Published: September 2023

SYNOPSIS

We designed, implemented, and evaluated a curriculum that trains accounting students and professionals in process mining, an important emerging technology that is not extensively taught in most degree programs. We partnered with a leading provider of process mining software to create the “Process Mining Audit Professional Badge.” The badge’s curriculum combines modules focused on generic process mining skills and modules focused on process mining applications in auditing settings. In 22 months, 1,532 individuals completed the curriculum. Learners were highly satisfied with the training, ranked it among the most effective training modalities they had experienced, and perceived that they learned a great deal about both process mining and the auditing process. We demonstrate an approach to developing materials on emerging technologies that is perceived as useful by learners. If adopted more broadly, the approach could facilitate curricular integration of skills demanded by the profession.
In Financial Statements We Trust: Institutional Investors’ Stockholdings after Restatements
Authors: Cahan Steven F. , Chen Chen , Chen Li
Published: September 2023

How prior trust moderates investor responses to restatements is unknown. We examine how societal trust affects the changes in institutional investors’ shareholdings around a restatement. We consider two competing hypotheses based on the erosion of trust and confirmatory bias. We find the change in institutional investors’ shareholdings around a restatement is more negative for investors from high trust areas compared to low trust areas, consistent with an erosion of trust where high trust institutional investors view the restatement as a violation of trust. Further analyses show that our findings vary with the regulatory or economic environment, type of institution, and type of restatement. Our results are also robust to different tests that address endogeneity and use alternative societal trust measures. Overall, we contribute to the literature by examining the role of societal trust in a dynamic setting where investors’ trust-based beliefs about the credibility of accounting information are not realized.

Authors: Zaqoot Hossam A
Published: September 2023

This study used the life cycle assessment (LCA) approach to evaluate the environmental impacts resulting from aquaculture ponds and associated activities. The assessment focused on eutrophication, acidification, global warming, energy use, and local nutrient emissions. Two farms, Fish Fresh and Al-Bahar, were analyzed to determine the contribution of different components in fish farming systems to various impact categories. Data on fish feed, onsite electricity, feed milling electricity, fuel intensity, water input, and fish production were meticulously collected through a comprehensive questionnaire and insightful interviews conducted over a one-year period in 2020. Furthermore, valuable information was diligently gathered regarding the nitrogen and phosphorus emissions in aquaculture ponds, with a focus on feed inputs. Environmental indicators were evaluated using a functional unit of 1 ton and 1 kg of live fish weight. Results reveled that global warming impacts varied between the two farms, with feed production being the primary contributor, accounting for 74.73% and 76.30% of total emissions, respectively. Acidifying emissions were mainly generated through fish production, accounting for 74.8% and 76.3% of the total for Fish Fresh and Al-Bahar farms, respectively. Eutrophication was primarily driven by fish production, while feed production and transportation operations also made noticeable contributions. The average emissions per kilogram of fresh fish were higher for the Fish Fresh farm compared to Al-Bahar in terms of global warming, acidification, and eutrophication. Energy consumption and water dependence also varied between the farms. These findings emphasize the importance of considering environmental impacts throughout the life cycle of fish farming in the Gaza Strip.

Authors: Rosbaco Nicolás , Parra Verónica , Sureda Patricia
Published: September 2023

Este trabajo presenta resultados parciales del análisis de un recurso que, no es nada más ni nada menos, que un problema matemático. Se utiliza la acepción de recurso de Adler, particularmente, las nociones de transparencia, visibilidad e invisibilidad de sus usos en la enseñanza de la matemática. Nos centramos aquí en analizar un problema en términos matemáticos y de las potencialidades que tienen algunos recursos tecnológicos tales como wxMaxima, GeoGebra, Scratch y ChatGPT para su resolución. Mostramos cómo el uso de los tres primeros permiten resolver el problema en su forma más general que, de lo contrario no sería posible, y las limitaciones del ChatGPT para proponer una solución. Se trata de un problema que los profesores pueden utilizar para provocar oportunidades de enseñanza en el estudio de funciones en una, dos o más variables y si se quiere también, permite el estudio de funciones poco convencionales (salir de los paraboloides, de las sillas de montar, que recurrentemente aparecen en los textos), estimulando a los profesores hacia la incorporación de nuevos recursos para la matemática escolar. Concluimos en la transparencia de estos recursos, en la potencialidad del problema y en las limitaciones del ChatGPT para su resolución.

Ambarzumyan theorem by zeros of eigenfunction
Authors: Kemaloglu Beyhan
Published: September 2023

In this short paper, we give the proof of the Ambarzumyan theorem by zeros of eigenfunctions (nodal points) different from eigenvalues for the one-dimensional p-Laplacian eigenvalue problem. We show that the potential function q(x) is zero if the spectrum is in the specific form. We consider this theorem for p-Laplacian equation with periodic and anti-periodic cases. If p = 0, results are coincided with the results given for Sturm-Liouvile problem.
Dynamic nature of analytical soliton solutions of the (1+1)-dimensional Mikhailov-Novikov-Wang equation using the unified approach
Authors: Kumar Amit , Kumar Sachin
Published: September 2023

In this work, we investigate the dynamical study of the (1+1)-dimensional Mikhailov-Novikov-Wang (MNW) equation via the unified method is investigated. This technique is used to obtain the soliton solutions, including the trigonometric function solution, the periodic function solution, the exponential function solution, the elliptic function solution, and other soliton-form solutions. All the obtained results in this work utilizing an effective unified method help gain a better understanding of the physical meaning and behavior of the equation, thus sheding light on the significance of investigating diverse nonlinear wave phenomena in physics and ocean engineering. These derived results are entirely new and never repeated in the previous works done by the other authors. For the interest of visual presentation and physical illustrations, we plot the graphical demonstrations of some of the specified solutions in 3-dimensional, contour, and 2-dimensional plots by using Mathematica software. Consequently, we observe that the acquired solutions of the MNW equations are anti-bell-shape, kink wave solution, solitary wave, periodic solution, multisoliton, and different types of soliton solutions.

Reniform Nematode Management Using Winter Crop Rotation and Residue Incorporation Methods in Greenhouse Experiments
Authors: Sandoval-Ruiz Rebeca , Grabau Zane J.
Published: September 2023

Rotylenchulus reniformis (reniform nematode, RN) is an important pathogen in cotton production. Cultural practices such as crop rotation and biofumigation—management of soil pathogens by biocidal compounds from crop residues—may help manage RN. The objective of this study was to evaluate the efficacy of winter crops for RN management through combinations of rotation and crop residue incorporation in a cotton greenhouse experiment. A total of 10 treatments were evaluated in soil inoculated with RN: three winter crops (carinata, oat, or hairy vetch) grown in rotation with no shoot organic matter (OM) incorporated (1–3), fresh shoot OM incorporated (4–6), or dry shoot OM incorporated (7–9), and a fallow control (10). Roots were re-incorporated in all treatments except fallow. Subsequently, cotton was grown. Oat and fallow were better rotation crops to lower soil RN abundances at winter crop termination than hairy vetch and carinata. After the OM incorporation treatments and cotton growth, oat was generally more effective at managing RN in cotton than carinata or hairy vetch. Within each crop, incorporation treatment generally did not affect RN management. Cotton growth was not consistently affected by the treatments.
Stress–dilatancy behaviour of remoulded Fujinomori clay
Authors: Szypcio Zenon , Dołżyk-Szypcio Katarzyna
Published: September 2023

The effect of the degree of consolidation and the stress path on the behaviour of remoulded Fujinomori clay for drained triaxial compression and extension was analysed using the Frictional State Concept. It is shown that the stress–dilatancy behaviour can be approximated by a linear general dilatancy equation given by the critical frictional state angle and two soil parameters. The newly formulated dilatant failure state is represented on the stress ratio plastic dilatancy plane by points lying on the friction state line defined by the friction state angle and the Friction State Concept parameters α=0 and β=1. It has been shown that the stress ratio–plastic dilatancy relationship, which is very rarely used in the interpretation of test results, is important for a complete description of the behaviour of soils during shearing.

Berbagai faktor lingkungan, antara lain komponen fisik rumah, fasilitas sanitasi lingkungan, dan perilaku prolingkungan, dapat menyebabkan penyakit berbasis lingkungan pada keluarga nelayan. Penelitian ini bertujuan untuk mengkaji kondisi komponen fisik rumah, sarana sanitasi lingkungan, dan perilaku pro lingkungan keluarga nelayan. Penelitian ini dilakukan di Desa Muara Siberut, Kabupaten Kepulauan Mentawai, terhadap 98 keluarga nelayan yang dipilih secara sistematik dan acak. Komponen fisik suatu rumah terdiri dari lantai, dinding, jendela ruang keluarga, jendela kamar tidur, ventilasi, langit-langit, penerangan, dan cerobong dapur. Sarana sanitasi lingkungan meliputi sumber air bersih, jamban, sarana pembuangan air limbah, dan tempat pembuangan sampah. Sedangkan perilaku pro lingkungan meliputi cara membuang sampah, pengendalian vektor penyakit, kebiasaan memakai alas kaki, kebiasaan membuka jendela, dan kebiasaan membersihkan halaman. Hasil penelitian menunjukkan 26,5% lantai rumah nelayan masih retak dan berdebu, diplester papan/tanah, 34,7% rumah tidak berdinding, dan 29,6% tidak memiliki plafon. 19,8% keluarga tidak memiliki akses terhadap sumber air bersih yang layak, 18,4% tidak memiliki akses terhadap toilet yang memenuhi persyaratan kesehatan, hanya 13,3% yang memiliki pembuangan air limbah yang memenuhi persyaratan, dan 29,6% tidak memiliki tempat pembuangan sampah. Hampir separuh keluarga nelayan di Muara Siberut tinggal di rumah dengan komponen fisik, fasilitas sanitasi lingkungan, dan perilaku pro lingkungan yang buruk. Peningkatan kondisi kesehatan lingkungan keluarga nelayan perlu menjadi perhatian pemerintah daerah karena akan mempengaruhi derajat kesehatan masyarakat secara keseluruhan
Greek parents' profile concerning the use of smart mobile devices and their educational applications by preschool and elementary school children
Authors: Aleksandraki Foteini , Zaranis Nikolaos
Published: September 2023

This study examines Greek parents' attitudes towards using smart mobile devices and their educational applications by children aged 4-7 in an informal learning context. The research sample comprised parents whose children attended Crete's public kindergartens and primary schools during 2020-2021. A 30-item Likert-scale questionnaire assessed parents' attitudes toward smartphones and their educational applications. The factor and cluster analyses were conducted, and three parent profiles emerged: neutral, sceptical, and optimistic. Neutral parents value the use of educational applications by their children. Sceptical parents are the ones who attach great importance to the adverse effects that the use of digital technology can have on their children. Optimistic parents are the ones who consider the use of educational applications essential but also are the ones setting ground rules regarding its use. Parents' views regarding smart mobile devices' use are of immense importance, as well as their general perspective, commitment, and support towards their children, as they greatly influence the latter's learning experiences at home.
