Authors: J. C. Uche , A. N. Udobi , C. B. Ndeche
Published: July 2024

The proprietary structure of land throughout Nigeria and among the Amaigbos in the Nwangele Local Government Area of Imo State was examined. The proprietary land structure, which sheds light on absolute and derivative interest, was the subject of the study. Despite the passage of the Land Use Act of I978, the Igbo people traditionally understood property ownership to be of the absolute interest and derived interest basically. The Amaigbo community was no exception to the sacredness of Igbo land ownership, which was further demonstrated by the practice of only transferring land to sons. Women are only permitted to use land by virtue of their status as daughters or wives in the family, which is similar to the derivative interest. Three periods comprised the ownership pattern: before, during, and after colonization. The analysis of this pattern is being conducted at present time. The study's data collection methods included important interviews and historical records. Land was not originally subject to sale, but as the population grew, land pledges, sales, and occasional land exchanges occurred. It was determined that the Amaigbo people now sell land and have welcomed the modernization and progress brought about by the colonial authority.

An empirical investigation of green supply chain management (GSCM) and environmental sustainability in Saudi manufacturing SMEs: The mediating role of operations analytics
Authors: Iqbal Tahir , Nourelhadi Tarig Khidir Eltayeb
Published: July 2024

Incorporating sustainability principles into Supply Chain Management (SCM) has received considerable attention in recent years, with a particular emphasis on Green Supply Chain Management (GSCM), which aims to reduce environmental consequences. Saudi Arabia has launched sustainability initiatives; however, the application of green SCM methods in SMEs in Saudi Arabian manufacturing has yet to be explored. Therefore, this research aimed to empirically assess the effect of GSCM in promoting environmental sustainability in Saudi manufacturing SMEs, focusing on the mediating function of operations analytics. Therefore, this study used a quantitative research technique to discover the link between the study variables—a rigorous questionnaire obtained primary data from managers and team leaders. SPSS was used for descriptive statistics, while SMARTPLS was used for structural equation modelling. The measurement model, path analysis, and indirect impact analysis were used to validate the research constructs and analyze the hypothesized associations. The findings support the evidence of direct positive links between green manufacturing, green business practices, eco-design and environmental sustainability in Saudi manufacturing SMEs. Conversely, no evidence was found to support the function of operations analytics as a bridge between green SCM and environmental sustainability. Although operations analytics can improve green SCM processes, more studies are needed to understand its full impact on environmental sustainability outcomes.

Published: July 2024

This research aims to investigate the factors that affect the performance of national resilience, which are suspected to be related to the elements of territorial entrepreneurship leadership, knowledge sharing, territorial development, and national defense intentions. The sample consisted of 278 inmates in the context of national resilience. Primary data was obtained through the distribution of questionnaires to the sampled respondents. The data was analyzed using the Structural Equation Modeling (SEM) technique with the help of the Analysis of Moment Structure (AMOS) software. The results of the data analysis indicate that the Territorial Entrepreneurial Leadership Strategy implemented thus far does not have a significant impact on the Territorial Development Strategy, State Defense Intentions, and National Resilience Performance. However, on the other hand, the Knowledge Sharing Strategy contributes significantly to enhancing the Territorial Development Strategy and National Resilience Performance. Similarly, it has been observed that the National Defense Intention plays a crucial role in improving National Resilience Performance. It can be concluded that the development of territorial communities needs to consider various strategies and factors, including leadership strategy, knowledge exchange, and national defense awareness, in order to achieve regional development goals and enhance national resilience comprehensively. Collaboration among local leaders, communities, and other stakeholders is key to designing and implementing effective programs in this context.

Authors: Ouhader Hanan , Sbai Asma , Kyal Malika El
Published: July 2024

We assess the cooperative network design's efficiency outcomes in Morocco's food wholesale distribution. Before joining the collaborative coalition, we provide decision-makers with an initial preference instrument to assess the environmental and financial effects of cooperative freight distribution. We assess the practicality of incorporating decisions from the Facility Location Problem (FLP) and Vehicle Routing Problem (VRP) into partnerships for sustainable freight transportation. The coalition utilizes a 3PL provider's fleet of cars, therefore the Vehicles are exempt from having to go back to the consolidation depot; as a result, the fundamental issue becomes an open location routing problem (OLRP). Although there have been several studies on open location-routing problems, their application to horizontal shipper collaboration is new. For diverse collaboration scenarios, our computational approach is founded on two-echelon OLRP under a multiple objective and periods’ framework. Every shipper involved in the partnership needs to receive gains. Therefore, evaluating the benefits to each individual shipper is essential for an effective and durable collaboration. This study addresses the issue of profit allocation to determine the collective and individual shipper's savings. By considering not just economic variables but also environmental factors, the Open LRP may help firms plan and optimize their collaborative supply chains in a more sustainable manner.

Authors: Murdapa Petrus Setya , Indrawati Chatarina Dian , Windyaningrum Theresia Liris
Published: July 2024

In the batch process, the company uses the same process facilities to produce various types of products. This allows businesses to change production in response to changes in market demand. Batch processes are widely used in industry. In many cases, batch processes provide several benefits over continuous processes, especially when the industry wants to ensure and maintain the quality standards of its products. This paper proposes a behavioral model of a single-stage batch processing system, using the language of system dynamics. When run, the behavioral model will provide an overview of how the system behaves. The system dynamics language is a formulation of a system of ordinary differential equations that is extracted from the real system being studied, in the form of a stock and flow diagram. The computation of this diagram is further implemented using software. Because it is actually a calculus method, the system dynamics language provides output data much faster than discrete simulation modeling. In this paper, the system behavior modeled is mainly loading, processing and unloading activities. The verification results carried out by testing it on two different case examples show that the model can sufficiently describe the behavior of the conceptual system logically so that the model can enrich experimental tool options related to batch production processes in the future.

Published: July 2024

The development of dairy farming in Nagari Lasi District Canduang, Agam Regency, West Sumatra Province, has provided the materials a massive source of biogas production. The number of cattle in Nagari Lasi has reached around 1000 heads, plus other livestock such as Buffaloes and Goats. The manufacture of digesters in the previous year's Community service activities was a success. It produces biogas and is used for cheese production and household supply. However, the amount of biogas produced is still tiny. To realize "Community-Independent Energy," power generator installation is necessary. The biogas supply must be in large quantities and available continuously for the generator to operate. Biogas currently produced by the digester is insufficient to produce the biogas required by the generator. Therefore, biogas production capacity needs to be improved by expanding the volume of the digester that will be processing cow dung into biogas. Increasing digester capacity has significantly increased biogas production, reaching 12 m3 per day. This amount is enough to be used as fuel for an electric generator continuously.

Published: July 2024

Indonesia is one of the leading Pulp and paper producers globally, with an estimated annual growth rate of 3.5%. However, domestic production has not yet fully met the domestic needs and export demand for paper. Currently, hydrogen peroxide (H2O2) and chlorine dioxide (ClO2) are the primary bleaching agents used in Pulp and paper production. This research aims to evaluate the effects of H2O2, ClO2, and temperature on product quality parameters, specifically the tensile and tear indices. The variations of ClO2 used are 2%, 0.4%, and 0.7%; H2O2 concentrations are 0.1%, 0.2%, and 0.4%; and the temperatures used are 75°C and 85°C. The study found that the addition of ClO2 at a concentration of 0.7% resulted in the highest tensile index of 76.9 N.m/g and a tear index of 3.5 m.N.m²/g. The addition of H2O2 at a concentration of 0.1% resulted in a tensile index of 83.9 N.m/g and a tear index of 9.4 m.N.m²/g. Temperature variations did not significantly affect the tensile and tear indices, with the tensile index reaching 9.35 m.N.m²/g. The addition of H2O2 is essential as it enhances the bleaching process and improves the mechanical properties of the Pulp, which is beneficial for optimizing bleaching conditions to enhance product quality, thus meeting both domestic needs and export demands.

Published: July 2024

Mercury (Hg) is a highly toxic heavy metal with no biological benefits, posing significant environmental and health risks upon exposure. This study investigates the adsorption characteristics of chicken eggshell-derived adsorbents for the removal of Hg from aqueous solutions. The adsorbent preparation involved washing, drying, calcination, and KOH activation. Results indicated that the 170-mesh size adsorbent exhibited the highest adsorption efficiency, achieving a 99.70% removal rate of Hg. adsorption capacity tests revealed values ranging from 79,90 to 88,90 mg/g, conforming to the Indonesian National Standard (SNI) for activated carbon. Functional group analysis using Fourier-Transform Infrared Spectroscopy (FT-IR) identified a significant increase in aldehyde and ketone groups post-activation. The adsorption process reached equilibrium within 90 minutes, with optimal removal efficiency observed at an initial Hg concentration of 3,0 mg/L. These findings suggest that chicken eggshell-based adsorbents are a cost-effective and efficient solution for mitigating Hg contamination in wastewater, offering a sustainable alternative to conventional methods.

Graph Theoretical Models for Enhancing Highway Connectivity and Safety in Vehicular Networks
Authors: Shivangni Jat
Published: July 2024

Vehicular networks play a crucial role in modern transportation systems, significantly impacting connectivity and safety on highways. This paper explores the application of graph theoretical models to enhance both connectivity and safety in vehicular networks. Graph theory, a branch of discrete mathematics, provides a robust framework for modeling and analyzing complex networks, including those formed by vehicles on highways. Our study begins by defining the vehicular network as a graph where nodes represent vehicles, and edges denote communication links between them. We employ various graph theoretical concepts such as connectivity, centrality, and network flow to evaluate and improve the network's performance. Key metrics, including the degree of nodes, clustering coefficients, and shortest path lengths, are utilized to quantify network connectivity and identify critical nodes and edges that influence overall network efficiency. One of the primary objectives is to ensure uninterrupted connectivity in the presence of dynamic and often unpredictable vehicular movement. To this end, we analyze the network's resilience to node failures and propose strategies to enhance robustness using redundancy and alternative routing paths. By incorporating concepts like k-connectivity and network diameter, we develop models that maintain high levels of connectivity despite the removal or failure of multiple nodes or edges. Safety is addressed through the lens of network stability and reliability. We investigate the impact of vehicular density, speed, and communication range on the network's ability to sustain reliable communication channels. Techniques such as dynamic topology management and adaptive power control are proposed to mitigate the risks associated with network fragmentation and communication delays. Furthermore, we introduce optimization algorithms that leverage graph partitioning and community detection to improve the management of vehicular clusters, facilitating efficient data dissemination and reducing the likelihood of congestion-related incidents. The proposed models are validated through simulations that mimic real-world highway conditions, demonstrating significant improvements in both connectivity and safety metrics. In conclusion, the application of graph theoretical models offers a promising approach to enhancing highway connectivity and safety in vehicular networks
The Forcing Circular Number of a Graph
Authors: S. Sheeja
Published: July 2024

Let S be a cr-set of graph G and let G be a connected graph. If S is the only cr-set that contains T, then a subset T⊆S is referred to be a forcing subset for S. A minimum forcing subset of S is a forcing subset for S of minimum cardinality. The cardinality of a minimum forcing subset of S is the forcing circular number of S, represented by the notation f_cr(S). f_cr (G) = min {f_cr(S)} is the forcing circular number of G, where the minimum is the sum of all minimum forcing circular-sets S in G. For several standard graphs, the forcing circular number is identified. It is demonstrated that there exists a connected graph G such that f_g (G)=a and f_cr (G)=b for every integer a≥0, and b≥0.

Analysis of Nonlinear Schrödinger Equations with Time-Dependent Coefficients: Stability and Decay Properties
Authors: Eric Howard
Published: July 2024

This study investigates the stability and decay properties of solutions to nonlinear Schrödinger equations (NLSEs) with time-dependent coefficients. Employing a blend of analytical and numerical methods, we delve into how temporal variations in coefficients influence the dynamics of wave functions. Our analysis reveals that time-dependent coefficients significantly affect the stability and decay rates of solutions, uncovering conditions that lead to either enhanced stability or accelerated decay. The findings highlight the critical role of coefficient temporality in dictating the behavior of NLSE solutions. These insights not only advance our theoretical understanding of NLSEs but also bear implications for practical applications in fields modeled by these equations. Our research opens avenues for exploiting time-dependent behaviors in designing systems with desired dynamical properties.

In order to solve the inconvenience of traditional metal flood gates installation and realize the effect of flood control, this study developed a new set of flood control equipment with plastic curtains readily available on the market and customized molds, and named it "Flexible Flood Control Screen". The advantages of this equipment are: easy and fast installation, and the installation can be completed by one person. In order to ensure the flood control effect of the flood control screen and observe the mechanical behavior of the curtain under the lateral water pressure of the flood, this study plans a series of experiments for the flood control screen, such as: static water pressure, impact, and creep experiment. The test data is compared with the analysis data of the finite element model to verify the reliability of the data obtained by computer simulation. In response to different flood control needs in the future, computer model can accurately predict the deformation and stress distribution of the screen.

Matematika sebagai suatu disiplin ilmu merupakan alat untuk berpikir, berkomunikasi, dan memecahkan berbagai masalah praktis. Peserta didik dengan tingkat pemahaman matematika yang baik dapat menuntun peserta didik mempunyai kemampuan numerasi yang baik pula. Kemampuan literasi numerasi adalah kemampuan menerapkan konsep bilangan dan kemampuan berhitung yang ada dalam kehidupan dunia nyata. Saat ini masih sedikit yang bisa memanfaatkan kemampuan literasi numerasi dan hal tersebut menjadi penyebab matematika dianggap mata pelajaran yang sulit bagi peserta didik. Ketika proses belajar mengajar, guru dapat mengidentifikasi kemampuan awal peserta didik menggunakan asesmen diagnostik. Salah satunya adalah asesmen diagnostik kognitif untuk melihat kemampuan awal peserta didik dari aspek kognitif. Asesmen ini dilakukan pada awal pembelajaran yang hasilnya dapat digunakan guru sebagai pertimbangan dalam merancang kegiatan pembelajaran sesuai kebutuhan peserta didik. Penelitian ini dilakukan di SMP Negeri 6 Semarang dengan subjek penelitian kelas VIII menggunakan penelitian kualitatif deskriptif yang berfokus untuk mendeskripsikan bagaimana kemampuan numerasi pada peserta didik dengan tingkat kognitif tinggi, sedang dan rendah materi relasi dan fungsi. Teknik pengumpulan data dengan observasi, test dan wawancara. Instrumen penelitian yang digunakan adalah soal asesmen diagnostik kognitif, soal test yang dapat memunculkan kemampuan numerasi dan panduan wawancara. Kemudian teknik analisis yang digunakan adalah reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian menyatakan kemampuan numerasi yang berbeda-beda pada tiga subjek penelitian. Peserta didik dengan tingkat kognitif tinggi telah menguasai seluruh indikator kemampuan numerasi. Peserta didik dengan tingkat kognitif sedang memenuhi dua indikator kemampuan numerasi. Selanjutnya peserta didik dengan tingkat kognitif rendah tidak memenuhi seluruh indikator kemampuan numerasi.

The source of the primary magmatic magma of the Upper Pliocene-Quaternary trachybasalt-trachyandesite volcanic complex of the central part of the Lesser Caucasus is investigated in the article. The distribution of rare earth elements in the rocks of the trachybasalt-trachyandesite complex indicates that the source of the vulcanite’s was a metasomatically altered garnetbearing mantle substrate. Based on the geochemical characteristics of moderately alkaline olivine basalts, it was determined that the source of the magma is a lithospheric mantle containing metasomatized phlogopite-garnet-rutile. Keywords: Lesser Caucasus; Upper Pliocene-Quaternary volcanism; Primary magma; Lithospheric mantle hosting metasomatized phlogopite-garnetrutile.

The problem of displacing hydrocarbon systems injected into the reservoir by water in zonally heterogeneous collectors is considered. In this case, the reservoir of circular shape, developed by a single central well, is assumed to consist of two zones with different reservoir and rheological properties. The solution to the problem is obtained, taking into account the incomplete displacement, compressibility of water, and PVT properties of the hydrocarbon system—phase transformation, mass exchange between phases of the hydrocarbon system. Based on the binary representation of the complex hydrocarbon system, a solution to the considered problem is obtained, and an algorithm for calculating the main indicators of the hydrocarbon displacement process to the well is proposed. This algorithm accounts for the fact that the reservoir has different reservoir and rheological characteristics in the near-wellbore region (internal zone) and the distant part of the reservoir (i.e., in the external zone). Keywords: Displacement; Gas-condensate mixture; Volatile oil; Heterogeneous reservoir; Water flooding; Binary model; Unsteady-state flow.

On the territory of Azerbaijan, Paleogene deposits are widespread and often have facies alteration. To address the issues of stratigraphic, paleogeography, facies and paleoecological directions, a detailed stratigraphic basis of both the region as a whole and its individual sections is required. This article presents the results of joint magnetobiostratigraphic studies of the Paleogene deposits of the Greater Caucasus (Azerbaijan) in order to clarify the boundaries of the Paleocene, Eocene, Oligocene and Miocene. Biostratigraphically dated Paleogene deposits of the Khilmili, Pirakushkul, Dzhangi sections (southern slope of the Greater Caucasus) were chosen as the object of study. Paleomagnetic studies of the Paleogene deposits of Azerbaijan showed frequent reversals of the geomagnetic field of this period. The results of scientific studies of the southern slope of the Greater Caucasus confirmed this fact. We have identified two paleomagnetic zones: 1) Khorem (Maastrichtian 70 Ma - Eocene 45 Ma) (zones of reverse polarity prevail in it, but the upper part of the Paleocene has a direct polarity) and 2) Sogdiana (RN-Oligocene and Miocene - characterized by alternating direct and reverse polarity paleomagnetic field). In the Lower Paleocene, 2 subzones of direct polarity were distinguished: Danian and Selandian. The position of the R-zone made it possible to draw the boundary between the Danian and Selandian stages. The identification of a paleomagnetic zone of reverse polarity contributed to the determination of the boundary between the Selandian and Thanetian stages. This result was confirmed by identifying changes in the micro-faunistic composition of deposits and observing the nature of variations in micro-floristic complexes. Such a paleomagnetic zone of reverse polarity is the benchmark (plug) for establishing the boundary between the Mons and Thanetian stages. Keywords: paleomagnetism; southern slope of the Greater Caucasus; Paleogene; magnetostratigraphic boundaries.
