Two-dimensional antimonene as a potential candidate for dioxin capture
Authors: Meshhal Moyassar , Ahmed Ashour , Shibl Mohamed , Aziz Saadullah , Kühn Oliver , Soliman Kamal
Published: July 2024

Among the serious environmental problems that attracted much attention from the broader public is the high toxicity of dioxins. Considerable efforts have been made to develop techniques and materials that could help in their efficient removal from the environment. Due to its high specific surface area and numerous active sites, outstanding structural and electronic proper- ties antimonene is considered for a variety of potential applications in different fields such as energy storage, electrocatalysis, and biomedicine. The present study adds to this portfolio by suggesting antimonene as a promising candidate for dioxin capture. Using density functional theory (DFT) calculations, we studied the adsorption of 2, 3, 7, 8-tetrachlorodibenzo-p-dioxin (TCDD) on pristine as well as Ca-, Ti-, and Ni-doped antimonene. Three configurations of the adsorption of TCDD on antimonene were analyzed. The results obtained from calculating ad- sorption energies, charge transfer, charge density differences, and densities of states (DOS) give evidence that antimonene outperforms other nanomaterials that have been previously suggested for dioxin capture applications. Therefore, we propose these substrates (i.e., pristine and doped antimonene) as potential capture agents for removing such toxic organic pollutants.
Nylon Analogue Substrates Allow for Continuous Quantification of Polyamidase Activity in Nylon-Degrading Enzymes
Authors: Rangaswamy Alana , Roy Francis , Keillor Jeffrey
Published: July 2024

Nylon-hydrolyzing enzymes have been of increased interest recently in the context of bioremediation. The aminohexanoate oligomer hydrolases (NylCs) are thus far the most promising biocatalysts identified to this end. Protein engineering has been used to increase the thermal stability of these enzymes, but relatively little work has been done to improve their catalytic activity, due in part to a lack of high-throughput assays. Herein we report the design, synthesis, and enzymatic hydrolysis of polyamide analogue substrates mimicking various nylon architectures. We observed hydrolysis of diamide analogues 2, 4, and 5 in a continuous and quantitative manner via a light-scattering assay, which is amenable to a high-throughput screen in 96-well plates. The reaction products were characterized by liquid chromatography-coupled mass spectrometry, revealing insight into the structural elements required for recognition of substrates by NylC enzymes. The assay may be performed in minutes at elevated temperatures, allowing for efficient screening of thermostable nylonase enzymes. The activity of the NylC enzymes towards substrate 2 correlated to their corresponding enzymatic hydrolysis of Nylon-6 film, indicating that these substrates are surrogates for bulk nylon hydrolysis. Finally, we demonstrate the applicability of this assay to cell lysate, further enabling protein engineering efforts.
Faster Sampling in Molecular Dynamics Simulations with TIP3P-F Water
Authors: Rosas Jiménez José Guadalupe , Fábián Balázs , Hummer Gerhard
Published: July 2024

The need for short time steps currently limits routine atomistic molecular dynamics (MD) simulations to the microsecond timescale. For long time steps, the numerical integration of the equations of motion becomes unstable, resulting in catastrophic crashes. Here, we combine mass repartitioning and rescaling to construct a water model that increases the sampling efficiency in biomolecular simulations without compromising integration stability and with preserved structural and thermodynamic properties. The resulting “fast water” is then used with a time step as before, while the reduced water viscosity and faster diffusion result in proportionally faster sampling of the larger-scale motions in the conformation space of both solute and solvent. We illustrate this approach by developing TIP3P-F based on the popular TIP3P model of water. A roughly two-fold boost in the sampling efficiency at minimal cost in accuracy is substantial and helps lower the energy impact of large-scale MD simulations. The approach is general and can readily be applied to other water models and different types of solvents.
Exploring The Drivers of Entrepreneurial Intentions Among Farmers in Tanzania's Agricultural Sector
Authors: Tambwe M. A. , Mapunda M. A.
Published: July 2024

Purpose: This paper investigates the entrepreneurial intentions of orange farmers in Muheza, Tanzania, by validating the extended theory of planned behaviour (TPB).
Design/Methodology/ Approach: The study used a quantitative method approach, with cluster and simple random sampling, to recruit 349 orange farmers.  The survey was conducted on 349 small-scale orange farmers in Muheza. To test the model, the constructs of entrepreneurship training, farmers’ attitudes, subjective norms, perceived behaviour control and entrepreneurial intention inputs were validated, followed by factor analysis and structural equation modelling.
Findings: The study's results revealed the crucial role of perceived behaviour control and attitudes in driving the entrepreneurial intention of orange farmers. This significant influence underscores the importance of these factors in the development of entrepreneurial intention among orange farmers. It was also found that attitudes and perceived behaviour control predicted the entrepreneurial intention of orange farmers but not subjective norms, providing valuable insights for future research and policy development.
Research Limitation: This study primarily focused on orange farmers in the Tanga Region, specifically in the Muheza District.
Practical Implication: The findings suggest a clear path for action. To foster and enhance the entrepreneurial intentions of orange farmers, the government and policymakers should concentrate on instilling positive attitudes and controlling perceived behaviour. By promoting a positive stance toward entrepreneurship, we can significantly boost the willingness of orange farmers to engage in commercial farming, thereby contributing to the growth and development of Tanzania's agricultural sector.
Social Implication: The study recommends policy options focusing on cultivating positive attitudes and perceived behaviour control among orange farmers to increase entrepreneurial intention, requiring concerted efforts from the government and policymakers.
Originality / Value/ Novelty: It contributes to the body of knowledge, addressing the gap regarding the drivers influencing orange farmers' entrepreneurial intentions. Furthermore, establishing validated drivers of entrepreneurial intention among Tanzanian orange farmers could significantly assist the government in promoting economic development and achieving its vision of becoming a semi-industrialized country.

Analysis of Viewing Paintings from the Perspective of Iconography
Authors: Li Min
Published: July 2024

Distinguished from purely formalistic research methods, iconography pursues the interpretation of the hidden historical and humanistic connotations behind artworks, and is a discipline that combines visual text and content analysis methods. Combining the three stages of iconography proposed by Panofsky, the paper studies Shizeng Chen’s Viewing Paintings from the perspective of iconography, summarizing the formation and change of the images and contents of the artworks in the cultural system and civilization at that time, as well as their implied ideology, and analyzing the hidden spirit of the times and the historical significance behind them, so as to expound their iconographic significance. Through an in-depth discussion at three levels: pre-pictorial iconographic description, iconographic analysis, and iconographic interpretation, the facts and surface contents reproduced in the images, the traditional level of literary, artistic, and cultural knowledge, as well as the interpretation of the potential meanings are revealed.

Authors: Mbulawa S.
Published: July 2024

Emerging and fastest-growing markets in Africa are developing their financial environment to attract investors and position themselves as an upcoming generation of strong and influential markets.

   The subject of this study is public expenditure outlays used to stimulate economic activity in emerging markets in Africa.

   The purpose of this study is to isolate the main determinants of government spending and the role of institutional quality.

   The relevance lies in the significance of maintaining such expenditures at optimal levels to benefit the economy.

   The scientific novelty lies in the analysis of the main factors explaining government spending to support policy formulation in emerging markets.

   This study applied the autoregressive distributed lag (ARDL) model to test both long-term and short-term dynamics. Based on the results, the study demonstrated both joint and long-run causality between the selected variables and government expenditure. Short-term causality is not confirmed. The study concluded that the Wagner law still holds, in which economic growth is coupled with an increase in expenditure. The Economic freedom index is more effective in controlling government expenditure than the POLITY 2 variable. This study offers some policy implications.
A Comparative Analysis of STEM Design Curriculum Policy for Country Development: A Case Study of Taiwan and Thailand
Authors: Lhakard P.
Published: July 2024

The aim of this comparative study is to analyze the STEM (Science, Technology, Engineering, and Mathematics) design curriculum policies in Taiwan and Thailand, focusing on their potential impact on national development.

   The research examines three key areas: 1) STEM educational developmentpolicies; 2) curriculum frameworks; and 3) teacher professional development. The methods employed in this study include a comprehensive review of relevant literature, policy documents, and curriculum frameworks from both Taiwan and Thailand. The analysis involves a comparative approach to identify similarities, differences, and best practices in STEM education policies and implementation strategies. The results indicate that both Taiwan and Thailand recognize the importance of STEM education for driving innovation and economic growth. However, Taiwan demonstrates a more comprehensive STEM policy framework and a stronger commitment to developing a skilled workforce. Taiwan’s curriculum framework emphasizes hands-on, project-based learning, interdisciplinary integration, and the incorporation of modern technologies, fostering critical thinking, problem-solving, and collaborative skills among students. In contrast, Thailand is in the early stages of establishing STEM regulations and aligning curricula with industry needs. Thailand’s evolving curriculum framework shows promise in promoting creativity, critical thinking, and practical problem-solving abilities. Regarding teacher professional development, Taiwan has a well-established system of ongoing training and industry-school collaboration, while Thailand is in the process of creating a STEM teacher competency program.

   The key conclusion of this study is that Taiwan’s well-developed STEM policy framework, with its focus on curriculum design and teacher professional development, demonstrates a more holistic approach to promoting STEM education compared to Thailand.

   Despite Thailand’s early stage of implementation, the country is showing encouraging progress in aligning its STEM policies with national development goals. The findings suggest that a comprehensive and integrated approach to STEM education, encompassing policy development, curriculum design, and teacher professional development, is crucial for effectively promoting economic growth and innovation in both Taiwan and Thailand.

Evaluation of the use of polyvinyl alcohol in the manufacture of pressed samples for X-ray fluorescence analysis
Authors: Segrenev A. S. , Prots M. E.
Published: July 2024

The reliability of the results of X-ray fluorescence analysis (XRF), which is widely used in determination of the elemental composition of various materials, largely depends on the quality of sample preparation. When producing pressed tablets for X-ray fluorescence analysis of trace elements, a binder is often used in a powder form, which requires significant time for thorough homogenization. We present the results of applicating a polyvinyl alcohol solution as a binder in the manufacture of pressed samples without using a substrate in determination of microelements by XRF. The parameters for obtaining a durable tablet with a homogeneous composition that matches the condition of minimum impact on the intensity of the analytical lines of the elements being determined are presented. It is shown that the optimal sample weight for the proposed method of producing pressed tablets is 7 g with the addition of polyvinyl alcohol in a ratio of 7:1, the optimal drying time for the tablet after pressing is 1 hour. The calculated variation coefficients of the analytical signal (<2%) indicate the homogeneity of the produced tablets. The maximum values of standard deviations of pressed tablets for the selected ranges of elements are much less than acceptable, which confirms the validity of the proposed method of sample preparation. It is also shown that during long-term storage and repeated measurements, pressed tablets with the polyvinyl alcohol solution retain their original structure and intensity of analytical lines of elements. The accuracy of measurements in the subsequent determination of rock-forming elements is consistent with their certified contents. The results obtained can be used to reduce the time spent on getting a representative pressed sample when using polyvinyl alcohol, determining elements without additional support (coating films), microelement and silicate analyzes from one sample.

Student knowledge about e-wallets has a positive and significant impact on student transaction interest based on the results, the t count is 10,160, which is greater than the t table, which is 1,989. 2. From the results of the deitemination coefficient test, it can be seen that the variable effect of student knowledge about e-wallets on interest in financial transactions is as much as 52.3%. This can be seen from the R value of squiarei in the variable knowledge of students about Islamic banks, which is equal to 0.523. The remaining 47.7% is affected by variables that are not included in the research being studied. On the other hand, e-wallets are not only understood as a place to store money electronically, but also as digital payments such as OVO, Gopay and DANA. and students not only feel comfortable, but also make payments easier because they can be done anywhere as long as the user is connected to the internet.
PENGGUNAAN LAYANAN JASA TRANSFER MELALUI MUAMALAT DIN (DIGITAL ISLAMIC NETWORK) DALAM MENINGKATKAN LOYALITAS NASABAH
Authors: Sudianto Sudianto , Linda Linda
Published: July 2024

Transfers at Muamalat Bank can be done without going to the bank directly, namely making transfers via Muamalat DIN. Muamalat DIN is a mobile banking application by Bank Muamalat which can be accessed by its customers. At Muamalat DIN there is a transfer service which allows users to make transfers via Muamalat DIN. The aim of this research is to determine the use of transfer services via Muamalat DIN (Digital Islamic Network) in increasing customer loyalty at Bank Muamalat KCP Sumenep. To find out customer problems using transfer services via Muamalat DIN (Digital Islamic Network) at Bank Muamalat KCP Sumenep. To find out more about the use of transfer services through Muamalat DIN in increasing customer loyalty, researchers used a qualitative field research approach. The methods used are interviews, observation, documentation. The results of this research show that using transfer services via Muamalat DIN can increase customer loyalty because customers do not need to come to the bank to make a transfer, just use the Muamalat DIN application. The obstacles faced by customers using transfer services via Muamalat DIN are that some customers experience network problems, system repairs at the bank and human error or customer errors in making transfers and blocking of the Muamalat DIN application due to errors in entering the TIN code.
Restrained Global Defensive Alliances in Graphs
Authors: Consistente Leocint , Cabahug Isagani
Published: July 2024

A defensive alliance in a graph G is a nonempty set of vertices S ⊆ V (G) such that for every vertex v ∈ S, |N[v] ∩ S| ≥ |N(v) ∩ (V (G) ∖ S)|. A defensive alliance S is called global if every vertex in V (G) ∖ S is adjacent to at least one member of the alliance S. In this paper, the concept of restrained global defensive alliance in graphs was introduced. In particular, a global defensive alliance S is a restrained global defensive alliance if the induced subgraph of V ∖ S has no isolated vertex. Here, some properties of this alliance were identified, and its bounds were also determined. In addition, the restrained global defensive alliance number was also formulated, along with characterizations of some special classes of graphs, specifically complete, complete bipartite, and path graphs.
Modified Inertial Krasnosel'skii-Mann Type Method for Solving Fixed PointProblems in Real Uniformly Convex Banach Spaces
Authors: Akuchu Besheng George , Aphane Maggie , Ugwunnadi Godwin , Okereke George Emeka
Published: July 2024

We present an altered version of the inertial Krasnosel'skii-Mann algorithm and demonstrate convergence outcomes for mappings that are asymptotically nonexpansive within real, uniformly convex Banach spaces. To achieve our results, we skillfully construct the inequality in equation \eqref{6} and apply it accordingly. Our findings support and broadly generalize a number of significant findings from the literature. We demonstrate, as an application, the generation of maximal monotone operators' zeros via fixed point methods in Hilbert spaces. Additionally, we solve convex minimization issues using our fixed-point techniques.
Differentiating Odd Dominating Sets in Graphs
Authors: Carbero Mary Ann , Malacas Gina , Canoy Sergio
Published: July 2024

Let $G=(V(G),E(G))$ be a simple and undirected graph. A dominating set $S\subseteq V(G)$ is called a differentiating odd dominating set if for every vertex $v\in V(G)$, $|N[v]\cap S|\equiv 1(mod\ 2)$ and $N_G[u]\cap S\neq N_G[v]\cap S$ for every two distinct vertices $u$ and $v$ of $V(G)$. The minimum cardinality of a differentiating odd dominating set of $G$, denoted by $\gamma_D^o(G)$, is called the differentiating odd domination number. In this paper, we discuss differentiating odd dominating set in some graphs and give relationships between the differentiating odd domination, odd domination, and differentiating-domination numbers. Moreover, we  characterize the differentiating odd dominating sets in graphs resulting from join, corona, and lexicographic product of graphs and determine the differentiating odd domination numbers of these graphs.

Chemical graph theory can be studied with the aid of mathematical tools called m-polynomials. M-Polynomials offer a potent tool for computing different topological indices associated with vertex degrees and analyzing degree-based structural information in graphs. By counting specific substructure types within them, they are able to encode information about the structure of molecules or networks. In this article, we have developed M-Polynomials with the help of different topological invariants such as first Zagreb (M1(β)), second Zagreb (M2(β)), second modified Zagreb (Mm2(β)), inverse sum (I(β)), harmonic index (H(β)) and Randic index (Rα0(β)) for the molecular structures of Triangular oxide TOX(r), Regular triangular oxide RTOX(r), Triangularsilicate TSL(r) & Regular triangular silicate RTSL(r) networks to introduce new closed formulas to get better understanding the applications of M-Polynomials and topological indices in mathematical chemistry especially in the field of QSAR and QSPR study with the help of some software like MATLAB. We have also discussed the graphical behaviors of the above-mentioned structures.

Abstract
The European Commission requested scientific and technical assistance in the preparation of a EU‐wide baseline survey of antimicrobial resistance (AMR) in bacteria from aquaculture animals. It is recommended that the survey would aim at estimating the occurrence of AMR in Aeromonas spp. isolated from Atlantic Salmon (Salmo salar), European seabass (Dicentrarchus labrax) and trout (Salmo trutta, Salvelinus fontinalis, Oncorhynchus mykiss) intended to consumption, at harvesting (at farm/slaughter), at the EU level and in addition, at estimating the occurrence and diversity of AMR of Escherichia coli, Enterococcus faecium, Enterococcus faecalis, Vibrio parahaemolyticus and Vibrio alginolyticus in blue mussel (Mytilus edulis) and Mediterranean mussel (Mytilus galloprovincialis) from production areas and at dispatch centres at the EU level. These technical specifications define the target populations, the sample size for the survey, sample collection requirements, the analytical methods (for isolation, identification, phenotypic susceptibility testing and further genotypic analysis of some of the bacteria targeted) and the data reporting requirements. The data to be reported by the EU Member States to support this baseline survey are presented in three data models. The results of the survey should be reported using the EFSA reporting system.

Lawang Sewu, un edificio histórico en la ciudad de Semarang, se erige como una de las principales atracciones turísticas de la zona. Iniciada en 1904 y terminada en 1918, esta emblemática estructura ha sufrido varias transformaciones en cuanto a su uso y propiedad. Inicialmente sirvió como sede administrativa de Nederlands-Indische Spoorweg Maatschappij (NIS), una corporación privada que opera en el sector ferroviario, Lawang Sewu tiene un valor histórico significativo dentro de la ciudad antigua.Para profundizar en la percepción del público sobre este renombrado edificio histórico y sus paisajes urbanos circundantes, se llevó a cabo un estudio para examinar el impacto de las estructuras altas en Lawang Sewu, así como en las experiencias visuales de los visitantes y el entorno histórico en general. La investigación se centró en un edificio de gran altura de nueva construcción cerca de Lawang Sewu, teniendo en cuenta su altura, diseño y color como atributos físicos clave, al tiempo que utilizaba las regulaciones gubernamentales de altura como punto de referencia. Se llevaron a cabo experimentos de simulación en una amplia gama de encuestados con diferentes características demográficas procedentes de las cercanías de Lawang Sewu
Repensando el mito de origen de la arquitectura en América. El ejemplo de Chile
Authors: González Carrasco Diego
Published: July 2024

El siguiente artículo, indaga sobre el lugar desde donde se sitúa la historia oficial de la arquitectura en el continente americano a partir de la idea de la cabaña primitiva como mito fundacional. Utilizando el caso de Chile como ejemplo, se plantea la inexistencia en los relatos que buscan dar con el origen a las arquitecturas nacionales de las preexistencias construidas de los pueblos originarios que habitaban los territorios previo a la llegada de los conquistadores españoles. A modo de propuesta, se hace un paralelo desde el relato del surgimiento simbólico de la arquitectura en el mundo occidental, con las características y relevancias de algunos ejemplos de patrimonio vernáculo construido indígena en Chile. Así, buscamos hacer una reflexión que posibilite un cambio en los referentes discursivos fundantes de la arquitectura en nuestro continente.

Published: July 2024

Today's young fashion consumers are seeking unique silhouettes to craft more appealing and aesthetic looks. The strong desire for individuality necessitates the exploration and utilization of basic silhouettes. Silhouettes serve as the core structure of the design, providing an authentic foundation upon which innovative solutions can be built. This study focuses on the redesign of additional articles of clothing for their multi-functional utility. Fashion accompaniments allow for the seamless integration of existing wardrobe pieces, significantly curbing excessive clothing consumption and waste, thus promoting sustainability. These versatile clothing pieces offer a range of styles, discouraging the need for frequent clothing purchases. This integrated approach can curb the impulsive buying habits among young fashion consumers presenting a creative solution for fashionable looks. The key is to familiarize customers with strategically planned wardrobes that include compatible detachable clothing pieces. Fashion accompaniments can be augmented to mix and match with existing wardrobe clothing pieces. Designers and fashion brands can be encouraged to focus on perennial clothing with a contemporary touch. It is crucial to educate consumers on the versatility of these accompaniments to effectively incorporate them into daily life. This study seeks to repurpose remnants from high fashion silhouettes into detachable pieces that can be transformed into new clothing designs. The adoption of simplified patternmaking concepts can minimize procurement costs. These silhouette overlays have the potential to revolutionize design and style experimentation, and traditional design boundaries. The transformation of basic shapes into versatile forms can unlock limitless possibilities for their optimal use, leading to an eco-friendly approach to fashion. The suitability of the silhouette to the figure type is a crucial factor in the selection process. The study proposed the implementation of CLO3D technology by brands to personalize looks and ascertain suitability to figure type for captivating results.
