Diabetes has continued to affect the well-being of millions of individuals all over the world. More than seventy percent of Africans have undiagnosed diabetes mellitus, with Nigeria among the list of the African countries recording most undiagnosed cases. Biologically synthesized gold nanoparticles using the extracts of plants have continued to gain grounds in the treatment of diabetes. In the present research, a straightforward green method was used to form gold nanoparticles (AuNPs) from Mangifera indica leaf extract. Transmission electron microscopy (TEM), dynamic light scattering (DLS), ultraviolet visible spectroscopy (UV-Vis), X-ray diffraction (XRD), and selected area electron diffraction (SAED) were used to characterize the nanoparticles. Using XRD and SAED, the AuNPs' crystallinity was ascertained. The TEM revealed particles of various morphologies, and the UV-Vis revealed a surface plasmon resonance (SPR) at 539 nm. The stability of the colloidal suspension was implied by the DLS measurement, which revealed a hydrodynamic size of 31.74 nm and a zeta potential of -23.7 mV. With percentage inhibitions that were about equivalent to that of acarbose, the conventional medication, the AuNPs demonstrated strong antidiabetic efficacy against the alpha-glucosidase and alpha-amylase enzymes. The research revealed the potential of Mangifera indica leaf extract-mediated gold nanoparticles in treatment of diabetes.

Authors: Ehigbochie Amenawon Imuwahen , Ekuobase Godspower Osaretin
Published: January 2025

Tech workers are not just employees but ubiquitous architects and drivers of the imminent digitalized future. Tech worker’s wellbeing is, therefore, crucial for global prosperity – necessitating their continuous monitoring and management in the workplace. Although a cross-cultural job satisfaction scale has been specifically developed and validated to help gauge the wellbeing of tech workers, christened JSST, it lacked an implementation guideline. This lack of implementation guidelines for the JSST questionnaire can stifle its practicality and, by extension, the wellbeing of Tech workers. The aim of this study, therefore, is to design an implementation guideline for JSST. The implementation guideline was designed using descriptive statistics and algorithmic specification. Adopting a self-assessment online survey on the original Five-point Likert JSST Questionnaire, this study also demonstrated  the implementation of the guideline. 276 valid Tech workers’ job satisfaction self-assessment data solicited globally using the JSST questionnaire was employed to demonstrate the guideline’s feasibility. Overall, the job satisfaction index of the global tech workers has been estimated to fall into the third quartile of satisfaction, Q3, which is low. This low satisfaction index may account for the high turnover and turn-away in the global Tech industry. A notable outcome of this study is the seamless JSST implementation scheme, which is not only effective but also highly adaptable. This scheme can be tailored for the implementation of any multi-faceted psychometric scale, making it a versatile tool for assessing employee wellbeing. The automation for web accessibility of the JSST implementation scheme is encouraged.

Published: January 2025

This study introduces the Odd Rayleigh-G (OR-G) family of distribution and explores its mathematical properties, applications, and performance comparisons. The Odd Rayleigh-Weibull distribution (ORWD) is developed by incorporating the "Odd" transformation into the Rayleigh and Weibull distribution, resulting in a flexible model suitable for various real-life and survival data applications. The probability density function (PDF), cumulative distribution function (CDF), hazard function, and survival function of the ORWD are derived and analyzed. Parameter estimation is performed using the Maximum Likelihood Estimation (MLE) method, and the performance of the ORWD is assessed through simulation studies. The simulations for parameter estimates at 100 sample sizes were conducted and the plot of the simulated data on the PDF, CDF, survival and hazard function demonstrate a comprehensive view of the characteristics of the Odd Rayleigh Weibull distribution. This information is useful for understanding the behaviour of the distribution and for applications in reliability analysis and survival studies. The results demonstrate the consistency and efficiency of the MLE method for the ORWD. The ORWD is compared with other distributions, including the Weibull, Power Rayleigh, and Rayleigh distributions, using goodness-of-fit measures such as the Akaike Information Criterion (AIC = 111.0238 and 87.4294), Bayesian Information Criterion (BIC = 117.2564 and 96.0320), and Kolmogorov-Smirnov (KS = 0.9559 and 0.9889) test with p-values (p-val = 7.772e-16 and 2.2e-16). The ORWD shows superior performance in fitting the mortality dataset and the Reddit advertisement dataset, highlighting its potential for modelling complex data structures. Overall, this study provides a comprehensive framework for the...

Published: January 2025

The Gombe Formation, situated in the northeastern region of Nigeria, contains shales in addition to various sedimentary lithologies such as sandstones, mudstones, and coals. Nonetheless, the comprehensive geochemical analyses of the major oxides of these shales remain inadequately documented to date. The current study aimed to elucidate the geochemical significance of major oxides of the shales from the Gombe Formation in the Upper Benue Trough, Nigeria, using x-ray fluorescence spectrometry (XRF) within the context of provenance, tectonic settings, and paleosalinity. The average concentration of the major oxides ranged from 0.02 to 34.93 % in the shales. Among the twenty-four (24) major oxides detected, the shales exhibit elevated concentrations of SiO2, with Al2O3>Fe2O3>SO3>MgO>CaO>SrO>BaO>K2O>TiO2>Sb2O3>CeO2>MnO, whereas the remaining oxides exhibited low concentrations. This observation implies that the shales were predominantly composed of quartz minerals and deposited in marine environments. The relatively high concentrations of Fe2O3 (with an average value of 3.36 %) and MgO (with an average value of 2.48 %) in the samples suggest that the source rocks were likely of a mafic to ultramafic nature. The values of Al2O3/TiO2 and SiO2/Al2O3 in the shales ranged from 1.75 to 11.02 and 6.95 to 38.44, respectively. These values indicated their derivation from a mixture of felsic igneous and mafic igneous rocks and mixed compositional maturity in proximity to the active continental margin. This study demonstrated that major oxides serve as a robust tool for assessing the provenance and tectonic characteristics of the shales from the Gombe Formation within the Gongola Basin, Nigeria.
ANALYSIS FROM 1980 TO 2018 OF TIDAL OBSERVATION DATA FOR ASSESSING THE STABILITY OF TIDAL CONSTANTS FOR PRIMARY PORT
Authors: Morakinyo Barnabas O.
Published: January 2025

Tidal analysis involves the computation of tidal constants (phase lag (g) and amplitude (H)) of tidal constituents at a location. This study focuses on the assessment of the stability of g and H for the Bonny port which is the only standard tidal port in Nigeria. Monthly analysis of tidal observations was carried out with 1980, 1994 and 2018 year’s data using Least Squares Method (LSM) of Harmonic Analysis with MATLAB programming codes. The observation equation technique of LSM is adopted; the dimension of the Normal (N) matrix equations obtained for the monthly analysis is 72  56 i.e. 72 rows, and 56 columns. The N matrix is inverted and gave results for mean sea level (MSL) and g and H of 28 primary constituents of tide. Four major constituents of tide (M2, S2, K1 and O1) remain stable throughout the analysis. The mean of g and H obtained for each year was observed to be almost equal to the mean obtained from the three-year data. The maximum residuals and spreads of the computed g and H over the period of study show that g and H at Bonny are stable and that results from accurately analyze one-month data observation can be employed for tidal prediction for several years. Therefore, it can be concluded that the g and H for M2, S2, K1 and O1 are stable and that the type of tide (F) at Bonny port is semidiurnal since the computed F is 0.16 which is  0.25.
SETTLEMENT OF CONSUMER DISPUTES BY CONSUMER DISPUTE RESOLUTION AGENCY
Authors: Vivi Hayati
Published: January 2025

Consumer dispute resolution outside the court through the Consumer Dispute Settlement Agency (BPSK) has become an increasingly important alternative in Indonesia's consumer protection legal system. This study aims to analyse the legal framework and the effectiveness of the BPSK in resolving disputes between consumers and businesses. The methodology used is a normative juridical approach, conducting literature studies on relevant laws and regulations, legal literature, and BPSK decisions. The results show that BPSK has a strong legal basis in the Consumer Protection Act, but there are several obstacles in its implementation, such as limitations in executorial authority and inconsistencies in legal interpretation. In conclusion, although BPSK has the potential to be an effective dispute resolution mechanism, regulatory improvements and institutional strengthening are needed to enhance legal certainty and consumer protection in Indonesia.
Research on Unmanned Path Planning of Intelligent Vehicle Based on Swarm Intelligence Algorithm
Authors: Yang Tao , Song Dandan
Published: January 2025

Unmanned vehicles represent a significant advancement in automotive technology, with their development hinging on sophisticated perception, decision-making, and control capabilities. However, existing path planning methods for driverless cars face challenges in complex road environments due to their susceptibility to environmental factors. This paper aims to address this issue by first providing an overview of trajectory planning algorithms for driverless cars. Subsequently, a novel global path planning approach is proposed, leveraging an improved A* algorithm and a predictive model of travel time. The proposed method enhances path planning accuracy by integrating the A* algorithm with predictive capabilities regarding travel time. By considering not only the shortest path but also the anticipated time required to traverse it, the model can account for dynamic factors such as traffic congestion and road conditions. This predictive aspect adds a layer of adaptability to the path planning process, enabling intelligent vehicles to make informed decisions in real-time. Simulation results demonstrate the efficacy of the proposed model in accurately planning trajectories for intelligent vehicles. The research results indicate that the prediction results of the bidirectional LSTM network are highly consistent with the actual values, demonstrating good predictive ability. From the perspective of prediction error, the MAE (Mean Absolute Error) of the bidirectional LSTM model is 7.3165, which is superior to the other three models. Especially compared with unoptimized BPNN, bidirectional LSTM reduced MAE, MAPE, and RMSE by 32%, 38%, and 3%, respectively, which fully demonstrates the advantages of bidirectional LSTM in processing time series data. It can accurately predict the inflow of road segments in real time and calculate the travel time of a future road segment.

This article starts from the phenomenon and problems of the Covid-19 pandemic which ultimately has an impact on various human activities, one of which is da'wah activities which are also hampered due to social restrictions and even prohibitions on carrying out religious activities in mosques for certain times. From here, researchers took the initiative to research da'wah efforts during the Covid-19 pandemic which will focus on the Maluku Branch of Yakesma. This research uses a qualitative approach. The results of the research show that in general, Yakezma does not face serious problems in carrying out its da'wah program during the Covid-19 pandemic, because the da'wah program that has been implemented is not only carried out face-to-face, but they can also carry out These activities are virtual, so that social restrictions and community movement, including restrictions on the use of places of worship resulting from the implementation of PSBB and PPKM policies to break the chain of spread of the corona virus, do not become an obstacle for Yakesma to continue implementing the program. his preaching. Apart from that, Yakesma's efforts in carrying out da'wah activities during the pandemic can be seen from their strategy in packaging their da'wah activities. From the results of data collection carried out by researchers, it shows that before the corona virus had pandemic status, and even before the PSBB and PPKM regulations were implemented, Maluku Yakesma was already running a da'wah program by utilizing digital-based information technology facilities. Yakesnya's da'wah program is carried out livestreaming via YouTube and Facebook and also in the form of short 1 minute videos uploaded to Instagram

Chronic imflammatory demyelinating polyneuropathy (CIPD) is a heterogenous group of disimmune polyneuropathies, characterised by progressive or relapsing-remitting disease course, with electrophysiologically and pathomorphologically detected peripheral nerve demyelination. Immunotherapy is considered reasonable in CIDP. CIDP associated with antibodies against nodo-paranodal proteins, namely, NF155, CNTN1, Contactin associated protein has been described amongst the rare atypical CIDP subtypes. The detection of antibodies against nodo-paranodal proteins might have a predictive value for a more severe disease course with resistance to corticosteroid and/or IVIG treatment. Herein we report a case of severe relapsing-remitting CIDP, characterized by respiratory muscle weakness requiring assisted ventilation, with a previous history of proteinuria, later also diagnosed with Minimal change disease (MCD).

Background: IKN development is like two sides of a coin in implementing consumer protection in East Kalimantan. In the midst of incomplete arrangements for implementing consumer protection due to the transfer of authority from districts/cities to provinces. As an implementation of decentralization and delegation, legislation is still regulated through a Gubernatorial Regulation which substantively only regulates BPSK technical matters. So the implementation of consumer protection is not yet optimal. Objective: of this research is to explore strengthening efforts to overcome problems in implementing consumer protection in East Kalimantan. Method: used is normative juridical, with a statutory approach, theory of authority, the principle of legal certainty, to explore philosophical, juridical and sociological values ​​as an effort to strengthen consumer protection regulations and using prescriptive analytics.
Results: of the analysis and discussion show that there is a delegation of authority for implementing consumer protection in regional autonomy as a concurrent matter. The implementation of consumer protection in East Kalimantan as an implementation of decentralization and delegation of authority has not been regulated in the form of Regional Regulations.
Conclusion: As a form of ensuring consumer protection in East Kalimantan, it is necessary to strengthen regional regulations related to consumer protection.

Published: January 2025

Fake news becomes a major concern in the era of social media, as it can spread rapidly and has significant impacts on individuals and society.Society and individuals are negatively influenced both politically and socially by the widespread increase of fake news either generated by humans or machines. In the era of social networks such as Facebook, X (twitter) and WhatsApp, the quick rotation of fake news makes it challenging to evaluate its reliability promptly. Therefore, automated fake news detection tools have become a crucial requirement. To address the aforementioned issues, twodata mining classification techniques were used as Extreme Gradient Boosting and Decision Tree with some python features. This study is designed to use Decision Tree and Extreme Gradient Boosting methods to develop an effective approach for detecting and classifying news as real or fake to obtain a reliable model performance. These models are trained on a labeled dataset consisting of bothreal and fake news. The performance of the models was evaluated using standard evaluation metrics such as accuracy, precision, recall, and F1-score. The proposed approach achieved 100% accuracy in distinguishing between real and fake news. It revealed andhighlighted the potential of utilizing data mining techniques to combat the spread of fake news and provide valuable insights for researchers and practitioners in the field of information confirmation/verification and media literacy. We hope to use a different dataset to test the proposed model.

Published: January 2025

The low thermal stability of cellulose presents unique technological challenges to the formulation of wood and plastic composites that are compatible and processable. For this, hydrothermal modification is a well-established technology for improving dimensional stability and durability of wood's components, in addition to providing better interaction with the polymer. This study produced polymer composites in which hydrothermally treated wood waste fibers (WT) reinforce a recycled polypropylene (RPP) matrix. Wood waste fibers were selected by grain size and distribution, treated hydrothermally, and characterized by SEM, ATR-FTIR, and water sorption. Composites were produced varying the reaction time of treatment hydrothermal (from 30 to 180 minutes), granulometric size (from 425 to 1400 μm) and percentage of WT (from 10 to 20%), following a 2³ full-factorial experimental design, by extrusion with internal recirculation and the mechanical test specimens were modulated by injection. Tensile, flexion, IZOD impact and water sorption tests were statistically analyzed. Reaction time was the most statistically significant factor. Composites of wood waste fibers treated for 30 min and containing 20% of WT presented better mechanical properties than expected. However, the preservation of the lamellar fibers during the reaction time allowed for better adherence to the polymer, and the insertion of a greater quantity of fibers in the material provided greater rigidity in the composite. In general, the results obtained gives properties of stability and resistance to damage of composites containing hydrothermally treated wood fibers.

Nowadays, multiple materials have been developed to
reconstruct human bone tissue and bone through organic waste
materials in order to reduce environmental pollution, such as
"chicken eggshells" due to their high calcium content from which
we can synthesize a bioceramic called "hydroxyapatite", that has
mimetic similarities with human tissues and bones. Within this
study, "San Juan" brand eggshells from "Nicolás Romero, State
of Mexico, Mexico" were used to synthesize materials that can
be used for calcium phosphate dental grafts; where this
biomaterial was synthesized and afterwards applied in dental
grafts focusing on cavities being damashed by caries produced
through time.

Published: January 2025

Factor analysis is considered to be a very important technique for the investigation
of complex situations, in the particular case of Internet addiction, as it allows
complex behavior to be broken down into more manageable and understandable
factors. This process facilitates the evaluation, intervention and understanding of its
implicit dimensions, so that a relationship of its impact on mental health could be
established. The validation of a questionnaire is a fundamental part of ensuring that
the measurement instruments are reliable and valid. One of the most used statistical
methods is factor analysis, this examines the hidden structure of the data and has a
certainty that measures what you want to quantify. The method of principal factors
and not principal components is used here. The objective of this research is to
determine the outstanding factors in the students of TecNM, Campus Mérida and
Campus Tuxtla Gutiérrez, who interact with the use of the Internet in a nonacademic way; subsequently validate the survey applied. A series of questions were
considered to determine if its use is excessive, the questionnaire contains 14
questions that deal with addictions related to behavior and its effect on their daily
performance and its possible relationship with academic performance.

Published: January 2025

Carbon quantum dots (CQDs) are spherical nanoparticles (CNPs) with a size between 2-10 nm
and a crystalline structure. They have unique properties, such as high biocompatibility and
luminescence produced by their absorbance and emission of light. This shows optical properties
that are not seen in larger scale materials. Due to their low toxicity, CQDs offer a versatile
platform for various applications, including medical diagnosis, bioimaging, substance detection,
controlled drug release, photodynamic therapy and biomarking techniques. They can be
synthesized by methods such as ultrasound and microwaves, pyrolysis, hydrothermal synthesis,
or exfoliation of carbon materials. Their study and development is an active area of research in
biotechnology, nanotechnology and materials science. This work focuses on the properties that
this type of nanoparticle has, the synthesis used for its manufacture and the possible uses as a tool
in different biotechnological processes.
