Authors: El Lateef E.M. Abd , Selim M.M. , Wali Asal M. , Abd El-Salam M.S.
Published: August 2023

Cropping sequences has been shown to increase crop yields and improve land utilization in many cases, through building up organic matter in poor soils which can be enhanced and improved crop production, as well as better quality. The objective of the current work was to determine the effect of application of organic compost at the rate of 10 m3 fd-1 under dissimilar crop rotation. So, field trials were conducted in sandy soil with four field crops in two different crop rotations in 4 successive winter and summer seasons. The treatments were: no compost (as control), compost applied annually (cumulative) or two treatments applied in alternate seasons (residual). The results indicated that crop yields from the seasonal application of compost were generally significantly greater than those resulting from applications made in alternate seasons in the two rotations. Significant differences were also observed between the two alternate seasonal applications of organic compost compared with the residual effect of compost applied in the previous season. The nutrient contents of wheat were small, being below the levels normally recommended for optimum production and trace element concentrations were adequate, except for copper which was low. A similar magnitude was reported for berseem except for zinc which achieved adequacy levels under cumulative compost applications. The present data highlight the major cumulative and residual agronomic value of compost in arable crop production on reclaimed lands for different crop rotations under such impoverished soils. It could be concluded from the existing study that selecting a proper cropping sequence along with managing organic fertilizer programs can produce higher yield, maintain soil health and improve crop production without jeopardizing soil native nutrients and soil nutrients balance.

Published: August 2023

Arbutus unedo L. is an important food on the nutritional side. Unfortunately, most of its production is lost by the lack of appropriate conservation techniques. This study was carried out to follow the evolution of physicochemical, microbiological and microscopic parameters of two stages of Arbutus unedo L. fruits maturation during a period of conservation between 01 February 2021 and 29 July 2021 in a sugar solution with the presence of a percentage of lemon juice 4%. The results revealed that the fruits soaked in a sugar solution with a concentration of 75% remained more stable during the 180 days of conservation than those soaked in an equal concentration solution, 50% of sugar. With a slight increase in pH and medium pH, accompanied by a significant decrease in water content and an increase in total aerobic mesophilic germs. Therefore, sugar improves the conservation of Arbutus unedo L. fruits in a high concentration.

IOT-Based Smart Irrigation System using DTMF and 8051 MCU
Authors: Varma V Sai Nitin , Gangula Yaswanth
Published: August 2023

Abstract: In almost every facet of agriculture and gardening, irrigation is the cornerstone activity, with the regular watering of plants and crops paramount to their growth and well-being. However, this essential task often proves burdensome for individuals preoccupied with daily commitments. For farmers, the significance of water supply is further emphasized, as rainwater assumes a critical role in sustaining their crops. While relying on the unpredictability of monsoon rains, canals, and groundwater resources, farmers face the challenges of ensuring a consistent and appropriate water supply, as each crop type necessitates distinct watering regimens. Any insufficiency in providing water to crops can lead to devastating consequences, resulting in the potential destruction of crops and plants. Addressing these challenges and aiming to revolutionize irrigation practices, this paper proposes an IOT-based Smart Irrigation System using DTMF (Dual Tone Multi-Frequency) and 8051 MCU (Microcontroller Unit) as an innovative and transformative solution. This cutting-edge system combines the power of DTMF technology with the versatility of the 8051 microcontrollers, enabling remote control and monitoring of the irrigation process. By leveraging the interactive capabilities of mobile or landline phones, the system allows users, including farmers and gardeners, to conveniently manage irrigation operations from a distance, reducing the need for constant physical presence. This intelligent irrigation system exhibits applicability in automating the irrigation processes of various settings, including gardens, nurseries, and greenhouses. By carefully regulating the water supply to plants based on specific predefined conditions, the system ensures the provision of an optimal and essential amount of water. As a result, the system achieves energy conservation while effectively mitigating any potential water scarcity issues.
Financial and instrumental support for adult children and depressive symptoms among older adults in China: Does gender make a difference?
Authors: Deng Yuanping , Chen Li , Chen Meizhu , Liu Jia , Li Yu
Published: August 2023

For this study we used the demographic data of 5,669 Chinese adults aged between 60 and 79 years, drawn from the 2018 China Family Panel Studies. The propensity score matching method was used to analyze the effect of providing financial and instrumental support for adult sons and daughters on the depressive symptoms of parents. We also tested for gender differences in this effect. The results showed that providing financial support was significantly associated with greater risk of depressive symptoms in men but not in women. By contrast, providing instrumental support reduced the risk of depressive symptoms in both men and women. These findings suggest that adult children should reduce their financial dependence on their parents and that parents should be encouraged to help their adult children by carrying out suitable instrumental support, which could promote parent–child communication and reduce risk of depressive symptoms in older adults.

Efficient and Secure Consensus and Privacy Protection Scheme for E-Commerce Consortium Blockchain
Authors: Wu Haoyang , Li Guangshun , Wu Junhua
Published: August 2023

The application of blockchain technology to the field of e-commerce has
solved many dilemmas, such as low transparency of transactions, hidden
risks of data security and high payment costs. However, there are still
constraints in the existing e-commerce consortium blockchain, such as
the leakage of users’ privacy information, the incomplete traditional
consensus algorithm, and the severely insufficient blockchain
performance. In this paper, we propose a secure and efficient
transaction model applicable to e-commerce consortium blockchain, aiming
at guaranteeing the security of user privacy information and transaction
data while improving the transaction processing efficiency of the
system. The model uses homomorphic encryption algorithm to maintain the
confidentiality of user transaction information, and improves the
Byzantine resistance of the Raft consensus algorithm while retaining its
simplicity and efficiency. The effectiveness of the scheme proposed in
this paper is demonstrated by experimental simulations.
CDNet: Cross-Domain Description and Detection for 2D - 3D Learning Local Features

Published: August 2023

By integrating descriptors with keypoint detectors, we can unlock the
possibility of achieving comprehensive image matching and retrieval,
which presents significant implications for various modern applications
in computer vision and image processing. Despite the numerous proposals
for learning-based feature detection and keypoint description in 2D or
3D, the matching between 2D images and 3D point clouds has not received
thorough investigation. In this work, we propose a two-branch fully
convolutional network framework that maps 2D images and 3D point clouds
into a latent space for feature description and feature point detection.
Our model leverages two parallel branches, one for extracting features
from 2D images and the other from 3D point clouds, while facilitating
information exchange through weight sharing. This approach enables us to
fully exploit the correlations between 2D images and 3D point clouds,
enhancing the expressive power of features and achieving more accurate
and robust performance in image matching and retrieval tasks.
Additionally, we have designed a novel loss function to enhance
descriptor performance and enable more accurate keypoint detection.
Finally, we extensively evaluate our model on the SceneNN and 3DMatch
datasets, demonstrating its strong performance in accurate and efficient
2D-3D image matching. Our findings have significant implications for
various applications, including augmented reality, autonomous
navigation, and 3D reconstruction.
A Energy Security Trading Scheme for Electric Vehicles based on Blockchain and Trust Mechanism
Authors: Xu Huixin , Li Guangshun , Wu Junhua
Published: August 2023

More and more people choose to use electric vehicles to protect the
environment and conform to the trend of sustainable development.
However, the increase in the number of electric vehicles may cause
problems with the overload of the grid, and electric vehicles have their
shortcomings of weak range. Vehicle-to-vehicle energy trading can
balance the load on the grid and alleviate the range anxiety of electric
vehicles. Existing studies focus more on transaction efficiency and
energy utilization, ignoring data security and user privacy during the
transaction process. To this end, this paper proposes a blockchain-based
V2V energy security transaction scheme, which records the data of the
transaction process on the blockchain, and realizes the registration,
authentication, and transaction process through smart contracts.
Furthermore, we propose a transaction matching scheme, which fully
accounts for both parties’ credibility and uses the Bayesian game to
determine the transaction price. Under the premise of an incomplete
exchange of information, both parties shall ensure the reliability of
the transaction and obtain the optimal price. Finally, the algorithm
performance is evaluated through simulation, which shows that the scheme
is close to the bidding price of both parties, and the high user
satisfaction ensures a higher matching success rate for both parties.
Considering the trust value matching and pricing scheme can be a good
way to limit the behavior of both sides of the transaction, and ensure
the credibility of both sides and the security of the transaction.

Super-resolution fluorescence microscopy techniques developed over the
past two decades have pushed the resolution limit for fluorescently
labeled molecules into the nanometer range. These techniques have the
potential to study bacterial macromolecular complexes such as secretion
systems with single-molecule resolution on a millisecond time scale.
Here we review recent applications of super-resolution fluorescence
microscopy in molecular bacteriology with a focus on bacterial secretion
systems. We also describe MINFLUX fluorescence nanoscopy, a relatively
new technique that promises to one day produce molecular movies of
bacterial molecular machines in action.

Published: August 2023

In a dielectric barrier reactor (DBD), plasma-assisted direct conversion
of CH4 and CO2 to liquid products (methanol, ethanol, etc.) under
atmospheric conditions was performed. Due to its excellent ability to
activate CO2 and promote chain growth, Fe is an ideal candidate for
catalyst design. Meanwhile, graphite carbon nitride (g-C3N4) with Lewis
and Brönsted basic sites further enhances its catalytic performance.
Therefore, combining Fe and g-C3N4 holds great potential for catalyst
synthesis and applications. In this paper, we prepared a highly active
catalyst (Fe/g-C3N4) using a non-noble metal by impregnating Fe onto the
g-C3N4 support. When 10% Fe/g-C3N4 was half-filled in the discharge
region, the conversions of CH4 and CO2 were 22% and 18%, respectively,
and the liquid product selectivity was 40.1%. In the liquid products,
the selectivity of alcohol liquid products can reach 35%, of which
methanol can reach 24.4%, higher than the reported 11.9%.
Interaction between Medium Voltage Lines and Forest Fires

Published: August 2023

In recent years, extreme weather has occurred frequently in the world,
and the contradiction between medium-voltage lines and wildfires has
become more and more serious. In order to study the interaction between
medium-voltage lines and wildfires, this paper builds a real fault
simulation platform and carries out simulation experiments. The research
is carried out from two aspects: the contact discharge between trees and
wires to ignite trees to induce wildfires and the impact of smoke and
flames caused by wildfires below the lines on the lines. The research
results show that there is a high possibility that the medium-voltage
line and the tree contact discharge will induce a mountain fire, and the
accident must be discovered within at least 40 seconds to effectively
prevent the further occurrence of the fire, and the relevant mechanism
explanation is put forward. When smoke and flames are emitted from the
line, a “particle bridge” will be formed. Under the ionization of gas
and inorganic salts, conductive conditions will be formed together to
cause discharge or breakdown. The breakdown field strength is about
57kV/m.
Multi-scenario source-grid-load-storage cooperative optimal scheduling considering multi-side complex type storage capacity configuration
Authors: Huang Hui , LI Yonggang , Liu Huazhi
Published: August 2023

To both enhance the flexibility of the power system and absorption
capacity of renewable energy connected to a grid and achieve the
efficient use and cooperation of multi-side complex type energy storage
resources on the source, grid, and load sides, a collaborative optimal
scheduling system architecture of source-grid-load-storage (SGLS)
considering multiple energy storage types was constructed. Latin
hypercube sampling and sample reduction based on k-medoids clustering
were adopted to generate the SGLS scenarios, considering the emergency
circumstances of the power system. The flexibility of the multi-scenario
power system was evaluated, and the battery energy storage stations,
pumped storage, and electric vehicles with sufficient capacity were
configured on the source, grid, and load sides, respectively, to
participate in the scheduling. A multi-scenario SGLS cooperative
optimisation scheduling model that considers multiple energy storage
capacity configuration types was constructed for economic and
environmental protection. Based on data-driven, a multi-objective
optimisation algorithm was proposed by using the Gaussian process
regression algorithm and non-dominated sorting genetic algorithm II,
combined with the manifold interpolation batch evolution mechanism.
Finally, using actual regional power grid data for verification, the
proposed strategy effectively reduces system operating cost, enhances
energy storage battery life, and improves the renewable energy
consumption capacity.
Curvature-based shape recognition: characterising and analysing voltaje dips
Authors: Sundriyal Nitin , Ramirez Juan , Bayro-Corrochano Eduardo
Published: August 2023

This study employs differential geometric algebra to offer a fresh
perspective on voltage sag and swell analysis. By utilising differential
geometry, simulated electrical signals can be visualised as curves. This
is made possible by describing the instantaneous amplitude of a
sinusoidal wave as a curve in Euclidean coordinates. This approach
effectively represents the Frenet-Serret frame rotation at each point
along the curve. In systems with derivative components, the velocity of
the moving frame denotes the rate at which events change, as the Frenet
structure is locally defined at every point along the curve. This
mathematical representation, utilising the Frenet frame, enhances our
understanding of phenomena such as sag and swell, in contrast to
traditional approaches that rely on the Clark and Park transformations,
which utilise two-dimensional forms to capture the details and portrayal
of an occurrence. The work emphasises the depiction of voltage through
curves and provides a geometric indicator of the pattern’s evolution
during operation.

Published: August 2023

The academic accounting labor market is experiencing rapid changes on several fronts. We examine accounting program leaders’ perceptions of Assistant Professor hiring criteria, including how the criteria have changed in recent years. We ask program leaders to provide qualitative perspectives, rate the importance of 56 possible hiring criteria, and, in a supplemental analysis, rank and rate four hypothetical Assistant Professor candidates. Based on responses from 54 accounting program leaders, the results reveal a complex setting with research and teaching considerations, a focus on collegiality and professional experience, and an increasing focus on diversity. Specifically, Research Intensive schools (Carnegie R1 and/or doctorate in business) are more top-tier research and top-tier doctoral program focused, while Non-Research Intensive schools (all others) are more focused on general skills, other refereed journals, practitioner research, teaching experience, service, CPA licensure, and other professional certifications.
Climate Change Risk Disclosures and Audit Fees: A Text Analytics Assessment
Authors: Gao Lei , Calderon Thomas G.
Published: August 2023

In this paper, we first conduct a longitudinal study of public companies’ climate change risk disclosures from 2005 to 2019. Results indicate that although the number of firms disclosing climate change risks increased over time, disclosure length and disclosure clarity did not improve consistently during the study period. It seems that firms temporarily adjusted their disclosure behaviors around 2010 to satisfy the SEC’s 2010 guidance regarding climate change disclosures. From that point forward, however, companies’ disclosure length and clarity declined. Climate change and disclosures in a client’s environment can elevate both inherent risk and audit risk. Accordingly, the second part of the study empirically examines whether climate change risk disclosures are embedded into the auditors’ risk model and associated audit prices. Results suggest that audit fees are significantly associated with climate change risk disclosure length and clarity, and lower climate change risk disclosure clarity is associated with higher audit fees.
Narcissism, Cooperative Trust in R&D Cooperation, and Risk-Taking
Authors: Yu Hongjian , Lin Xinrui , Fan Ying Han , Yan Tianchi , Chen Yizao
Published: August 2023

The aim of this study is to investigate how CEOs’ narcissism influences their trust in their counterparts and risk-taking in joint research and development (R&D) projects under different equity allocations. Using an experimental design and a sample of 80 participants, we find that the high-narcissism participants have less trust in their counterparts but are more likely to invest in joint R&D projects under either high or equity allocation owing to their narcissistic personalities. This suggests that highly narcissistic participants are more likely to take risks in R&D cooperation. The results of our study imply that individuals’ narcissism poses a serious threat to R&D cooperation and business resources.

Published: August 2023

Accounting studies often examine whether the relation between X and Y varies with a moderating variable, M, by including an interactive term, X × M, in a regression. We provide plain-English guidance on why, how, and when to use control variables, Z, in interaction tests. A simulation and simple descriptions demonstrate how interacted controls affect coefficient estimates and interpretations. In particular, we demonstrate how controlling for Z without an accompanying interaction of X × Z and/or M × Z generally does not eliminate the confounding effect of Z on X × M. We conclude with guidance for future research.

Data Availability: Stata code to produce the simulations in this paper is available, as linked in the text.

Is it a Curse or a Blessing? Black Elk’s Attitude towards his Vision in Neihardt Black Elk Speaks
Authors: Al-Juaid Masha'il
Published: August 2023

This paper is a detailed analysis of Black Elk’s great vision in Black Elk Speaks written and documented by John G. Neihardt. It detects Black Elk’s possible intentions behind disclosing his full vision to Neihardt for the first time. This paper tracks the sequence of events and developments changing accordingly with the vision’s progression. It discerns Black Elk’s altering perspective on the vision from resisting it to utilizing it to enlighten people. In addition, this paper lists the burdens that come with the vision and shows how they effected Black Elk mentally and physically. Furthermore, it demonstrates how the vision reflects many of the Native American cultural aspects such as associating each one of the four main directions with a specific colour. It also detects the vision’s elements similarity to ones from other foreign cultures which resulted in questioning the vision’s authenticity such as the Mandala and wheeled carts. Finally, the paper examines doubting critiques and interpretations made by critics and thinkers on the truth behind the vision.

Haciendo Palmas: un trabajo de sistematización sobre la práctica de extensión
Authors: Gandini Tresols Carmelo , Ortega Cayata Tania
Published: August 2023

El objetivo es visibilizar, desde la sistematización, el trabajo realizado dentro del proyecto de extensión “Haciendo palmas” en el territorio “Las palmeras”, de la ciudad de La Plata. A su vez tiene como fin remarcar la importancia que posee, en las infancias y adolescencias, la intervención desde el juego, la recreación y el deporte que, además de ser derechos fundamentales desde el cual lxs niñxs pueden expresarse y generar vínculos con otrxs, constituyen una práctica valiosa para la construcción de sujetxs críticxs en la sociedad. Dicho trabajo se enmarca en la concepción de extensión crítica, tributaria de los procesos emancipatorios de Latinoamérica vinculados, fundamentalmente, a los movimientos obreros, campesinos y estudiantiles y vinculadas a las concepciones de educación popular que surgieron al calor de las luchas sociales del continente en la segunda mitad del siglo XX.

The oscillation theory of differential equations is an important branch of performance of differential equations, which is widely used in engineering control, vibration mechanics, mechanics, and industry. Therefore, the vibration performance of different parts has attracted people’s attention, and a lot of research work has been done. For a special class of delay differential equations - advanced piecewise continuous differential equations, the oscillation of numerical solution is discussed. The θ − method is used to discretize the equation, and the numerical method is obtained to keep the oscillation of the analytical solution of the equation, progressive conditions. At the same time, four different states of the dynamic behavior are discussed in detail for the analytical solution and the numerical solution respectively. Some numerical examples further verify the corresponding conclusions.
Global efficiency estimation of complex networks and regional technological and economic development based on fractal network model
Authors: Zu Yue
Published: August 2023

To accelerate the construction of transportation infrastructure, vigorously develop the transportation industry, drive economic development, and stimulate the growth of the national economy, the author puts forward the research on the relationship between highway traffic networks and regional economic development based on the fractal network model. Taking the road traffic network of 17 prefecture-level cities in A province as the research object, the fractal dimension of each grade of the road network is calculated with fractal technology, and the weight dimension model for measuring the comprehensive road network is constructed. The empirical results show that the fractal dimension of the regional road network is affected by the size of the road network, and then the prefecture-level cities are zoned, the correlation analysis is made on the road network weight dimension, trunk line fractal dimension and comprehensive economic index of various regions. The study found that the fractal dimension of the road network in each city was positively correlated with the comprehensive economic index, indicating that the more uniform the road network coverage, the more complex the traffic network, the better the economic development of the region. In order to further explore the coordination between highway construction and economic development in each city, the fractal dimension of 17 prefecture-level cities is calculated by introducing the fractal model of highway scale and economic output, it is found that the economic development of 6 cities including 1 city is ahead of the highway scale, 4 cities including 4 are the same, and the economic development of 7 cities including 2 cities lags behind the highway construction scale. Although the weight dimension does not represent there present your state of all classes of highways in a spatial form, it is based on the spatial fractal of all classes of highways, the weight value of the road capacity is integrated, which can highlight the advantages in the horizontal comparison with the fractal situation of the comprehensive road network in the same level areas.
