Analyzing the Relationship between Risk Management Strategies and Supply Chain
Authors: Nureen Puteri
Published: November 2024

Purpose: The purpose of this article examined how different risk management strategies affect supply chain resilience in Malaysia. It aims to identify effective strategies, such as supplier diversification and digitalization, that help Malaysian companies mitigate disruptions. The findings offer insights to enhance operational continuity and adaptability within Malaysia's unique risk environment.
Methodology: This study adopted a desk methodology. A desk study research design is commonly known as secondary data collection. This is basically collecting data from existing resources preferably because of its low cost advantage as compared to a field research. Our current study looked into already published studies and reports as the data was easily accessed through online journals and libraries.
Findings: The study found that effective risk management strategies, like supplier diversification and real-time monitoring, significantly enhance supply chain resilience in Malaysia. Companies adopting these strategies experienced fewer disruptions and quicker recovery times. However, challenges such as high costs and limited technology access still hinder broader adoption among smaller firms.
Unique Contribution to Theory, Practice and Policy: Resource-based view (RBV), contingency theory & high reliability theory (HRT) may be used to anchor future studies on the relationship between risk management strategies and supply chain resilience in Malaysia. Practically, companies should implement risk management strategies that are tailored to their specific supply chain contexts and risks. At the policy level, governments and industry bodies should support the adoption of resilience-enhancing technologies by offering financial incentives or subsidies, particularly for small- and medium-sized enterprises.

Authors: Vanesyan Anna , Mkhitaryan Liza
Published: November 2024

Introducción. El lagoftalmos cicatricial del párpado superior es una complicación seria pero poco común de la blefaroplastia, pudiendo causar sequedad ocular, irritación, conjuntivitis e incluso pérdida de visión. El objetivo de este estudio fue analizar los tratamientos no quirúrgicos del lagoftalmos cicatricial de párpado superior, por medio de una búsqueda sistemática de la literatura llevada a cabo sobre las principales bases de datos. Material y método. Se realizó una búsqueda de la literatura en inglés publicada entre el 1 de enero de 2013 y el 1 de diciembre de 2023, excluyendo estudios centrados únicamente en técnicas quirúrgicas o en el tratamiento de otras formas de lagoftalmos. Tras un proceso de selección, se identificaron 15 artículos relevantes. Resultados. Los tratamientos no quirúrgicos, como la inyección de toxina botulínica tipo A (TBA), de ácido hialurónico (AH) y el láser, han mostrado efectividad en la reducción de cicatrices en casos de lagoftalmos cicatricial. La inyección de AH ayuda a mejorar el cierre del párpado, mientras que el tratamiento con láser promueve la remodelación del colágeno para aproximar las características de la piel cicatricial a las normales. Además, el uso de 5‑fluorouracilo y productos cosméticos tópicos también se indica como alternativas para modular las cicatrices en esta condición. Conclusiones. A partir de los estudios analizados, se concluye que la TBA y el AH son los tratamientos no quirúrgicos más estudiados para el lagoftalmos cicatricial. Sin embargo, se destaca la necesidad de realizar ensayos clínicos para evaluar más a fondo la eficacia de estos tratamientos en la corrección del lagoftalmos postoperatorio del párpado superior.

Authors: Hamdan Khairul Hazim , Panjasaram Prasanth , Thanapal Mohana Raj , Ibrahim Mohd Razali
Published: November 2024

Background : Pelvic exenteration offers potentially curative resection for locally advanced pelvic malignancy. A dedicated unit performing this complex surgery is recommended to achieve optimal outcomes. Objectives : The aim of this paper is to show that pelvic exenterations can be performed with acceptable oncological and safe perioperative results in an appropriately resourced specialist centre. Methods : Patients undergoing pelvic exenteration in the Colorectal Unit, Hospital Kuala Lumpur between January 2017 and January 2024 were included. Patients operated in the initial setup period of the unit (January 2017 – July 2020) were compared to the second half (August 2020 – January 2024) with univariate analysis. Results : A total of 30 patients were included, with a significant increase in the unit caseload over the study period (n = 11 versus n = 19). There was an increased use of neoadjuvant therapy and an increase in stage of disease at presentation (p = 0.014) in the second half of the study period. More complex procedures were performed in the latter period, involving both bony and pelvic side wall resections. There was no difference in complication severity (Clavien Dindo) (p = 0.257) and R0 resection was achieved in 76.7% of operated cases. Conclusion : The development of a dedicated pelvic exenteration unit, leads to an increase in patient volume and an increase in the complexity of the procedures performed, without compromising short term outcomes and safety.
A Case of Disseminated Tuberculosis with Atypical Presentation In An Older Person
Authors: Ng Tyng Sam , Tunku Jaafar Tunku Muzafar Shah
Published: November 2024

Tuberculosis (TB) is an infectious disease caused by Mycobacterium tuberculosis. It is a significant health concern, with millions of new cases and deaths reported each year. Disseminated tuberculosis (dTB) is a serious condition which can affect various organs and tissues, leading to widespread symptoms and complications. The diagnosis of dTB can be challenging due to its atypical presentations. We present a case of dTB in a robust older person who presented with musculoskeletal pain, weight loss, and loss of appetite. Initially, he was treated for age-related spine disease, and pain management was provided. However, his subsequent visit raised suspicion of TB, prompting further work up. The diagnosis was revised to dTB, and anti-TB treatment was initiated. The near miss or delay in diagnosis and treatment may have played a role in dissemination of disease, increased frailty and reduction of function in this patient. Healthcare workers must maintain a high index of suspicion and remain vigilant for TB as starting early treatment will prevent dissemination in the patient, reduce risk to the public and improve outcomes.

Abstract. Accurate representation of the hourly variation in the NO2-column-to-surface relationship is essential for interpreting geostationary observations of NO2 columns. Previous research indicated inconsistencies in this hourly variation. This study employs the high-performance configuration of the GEOS-Chem model (GCHP) to analyze daytime hourly NO2 total columns and surface concentrations during summer. We use measurements from globally distributed Pandora sun photometers and aircraft observations over the United States. We correct Pandora total NO2 vertical columns for (1) hourly variations in effective temperature driven by vertically resolved contributions to the total column and (2) changes in local solar time along the Pandora line of sight. These corrections increase the total NO2 columns by 5–6 × 1014 molec. cm−2 at 09:00 and 18:00 across all sites. Fine-scale simulations from GHCP (∼12 km) reduce the normalized bias (NB) against Pandora total NO2 columns from 19 % to 10 % and against aircraft measurements from 25 % to 13 % in Maryland, Texas, and Colorado. Similar reductions are observed in NO2 columns over the eastern US (17 % to 9 %), the western US (22 % to 14 %), Europe (24 % to 15 %), and Asia (29 % to 21 %) when compared to 55 km simulations. Our analysis attributes the weaker hourly variability in the total NO2 column to (1) hourly variations in column effective temperature, (2) local solar time changes along the Pandora line of sight, and (3) differences in hourly NO2 variability from different atmospheric layers, with the lowest 500 m exhibiting greater variability, while the dominant residual column above 500 m exhibits weaker variability.

Published: November 2024

Abstract. During multiple field campaigns, small quasi-spherical ice crystals, commonly referred to as frozen droplets (FDs), and their aggregates (frozen-droplet aggregates, FDAs) have been identified as the predominant habits in the upper regions of deep convective clouds (DCCs) and their associated anvils. These findings highlight the significance of FDs and FDAs for understanding the microphysics and radiative properties of DCCs. Despite the prevalence of FDs and FDAs at the tops of DCCs where they directly contribute to cloud radiative effect, the detailed single-scattering properties (e.g., scattering-phase function P11 and asymmetry parameter g) of FDs and FDAs remain highly uncertain. This uncertainty is mainly due to insufficient in situ measurements and the resolution of cloud probes, which hinder the development of idealized shape models for FDs and FDAs. In this study, two shape models, the Gaussian random sphere (GS) and droxtal (DX), are proposed as possible representations for the shapes of FDs and FDAs measured in situ. A total of 120 individual models of GSs and 129 models of DXs were generated by varying their shapes. Furthermore, by attaching these individual models in both a homogeneous and heterogeneous manner, three different types and a total of 404 models of FDAs were created: (1) aggregates of GSs; (2) aggregates of DXs; and (3) combinations of GSs and DXs, which are called habit mixtures (HMs). The P11 and g values of the developed models were calculated using a geometric optics method at a wavelength of 0.80 µm and then compared with those obtained using a polar nephelometer (PN) during the CIRCLE-2 field campaign to assess the models. Both individual-component ice crystals (i.e., either GS or DX) and homogeneous-component aggregates (i.e., either aggregates of GSs or aggregates of DXs) showed substantial differences compared with the PN measurements, whereas the P11 of the HMs was found to most accurately match the P11 measured in situ, reducing the differences to +0.87 %, +0.88 %, and −5.37 % in the forward-, lateral-, and backward-scattering regions, respectively. The g value of the HMs was found to be 0.80, which falls within the range of the PN measurement (0.78 ± 0.04). The root-mean-square error for the HM was minimized to a value of 0.0427. It was shown that the novel HMs developed in this study demonstrated better performance than in previous research where HMs were developed indirectly by weighting the calculated P11 of shape models to interpret in situ measurement. The results of this study suggest potential implications for enhancing the calculation of single-scattering properties of ice crystals in DCCs.
Revealing dominant patterns of aerosol regimes in the lower troposphere and their evolution from preindustrial times to the future in global climate model simulations

Published: November 2024

Abstract. Aerosols play an important role in the Earth system, but their impact on cloud properties and the resulting radiative forcing of climate remains highly uncertain. The large temporal and spatial variability of a number of aerosol properties and the choice of different “preindustrial” reference years prevent a concise understanding of their impacts on clouds and radiation. In this study, we characterize the spatial patterns and long-term evolution of lower tropospheric aerosols (in terms of regimes) by clustering multiple instead of single aerosol properties from preindustrial times to the year 2050 under three different Shared Socioeconomic Pathway (SSP) scenarios. The clustering is based on a combination of statistic-based machine learning algorithms and output from emissions-driven global aerosol model simulations, which do not consider the effects of climate change. Our analysis suggests that in comparison with the present-day case, lower tropospheric aerosol regimes during preindustrial times are mostly represented by regimes of comparatively clean conditions, where marked differences between the years 1750 and 1850 emerge due to the growing influence of agriculture and other anthropogenic activities in 1850. Key aspects of the spatial distribution and extent of the aerosol regimes identified in year 2050 differ compared to preindustrial and present-day conditions, with significant variations resulting from the emission scenario investigated. In 2050, the low-emission SSP1-1.9 scenario is the only scenario where the spatial distribution and extent of the aerosol regimes very closely resemble preindustrial conditions, where the similarity is greater compared to 1850 than 1750. The aerosol regimes for 2050 under SSP3-7.0 closely resemble present-day conditions, but there are some notable regional differences: developed countries tend to shift towards cleaner conditions in future, while the opposite is the case for developing countries. The aerosol regimes for 2050 under SSP2-4.5 represent an intermediate stage between preindustrial times and present-day conditions. Further analysis indicates a north–south difference in the clean background regime during preindustrial times and close resemblance of preindustrial aerosol conditions in the marine regime to present-day conditions in the Southern Hemispheric ocean. Not considering the effects of climate change is expected to cause uncertainties in the size and extent of the identified aerosol regimes but not the general regime patterns. This is due to a dominating influence of emissions rather than climate change in most cases. The approach and findings of this study can be used for designing targeted measurements of different preindustrial-like conditions and for tailored air pollution mitigation measures in specific regions.
Anticorrelation of net uptake of atmospheric CO2 by the world ocean and terrestrial biosphere in current carbon cycle models
Authors: Schwartz Stephen E.
Published: November 2024

Abstract. The rate at which atmospheric carbon dioxide (CO2) would decrease in response to a decrease in anthropogenic emissions or cessation (net zero emissions) is of great scientific and societal interest. Such a decrease in atmospheric CO2 on the centennial scale would be due essentially entirely to transfer of carbon into the world ocean (WO) and the terrestrial biosphere (TB), which are sink compartments on this timescale. The rate of decrease in excess atmospheric CO2 and the apportionment of this decrease into the two sink compartments have been examined in two prior model intercomparison studies, subsequent either to a pulse emission of CO2 or to abrupt cessation of anthropogenic CO2 emissions. The present study examines and quantifies inter-model anticorrelation in those studies in the net rate and extent of uptake of CO2 into the two sink compartments. Specifically, in each study the time-dependent coefficients characterizing the net transfer rate into the two sink compartments (evaluated as the net transfer rate normalized to excess atmospheric CO2 above the pre-pulse amount for the pulse experiment or as the net transfer rate divided by excess atmospheric CO2 above the preindustrial amount for the abrupt cessation experiment) were found to exhibit strong anticorrelation across the participating models. That is, models for which the normalized rate of uptake into the WO was high exhibited low uptake rate into the TB and vice versa. This anticorrelation in net transfer rate results in anticorrelation in net uptake extent into the two compartments that is substantially greater than would be expected simply from competition for excess CO2 between the two sink compartments. This anticorrelation, which is manifested in diminished inter-model diversity, can lead to artificially enhanced confidence in current understanding of the consequences of potential future reductions of CO2 emissions and in the global warming potentials of non-CO2 greenhouse gases relative to that of CO2.
RiverBedDynamics v1.0: A Landlab component for computing two-dimensional sediment transport and river bed evolution
Authors: Monsalve Angel D. , Anderson Samuel R. , Gasparini Nicole M. , Yager Elowyn M.
Published: November 2024

Abstract. Computational landscape evolution models (LEMs) typically comprise at least two coupled components: a flow hydraulics solver that routes water across a landscape and a fluvial geomorphological model that modifies terrain properties, primarily bed surface elevation. LEMs used in long-term simulations over large watersheds, including some available in the Landlab library, often assume that only erosive processes occur in rivers and that terrain elevation increases solely due to tectonic uplift. Consequently, these models cannot capture the dynamics of gravel-bedded rivers, lacking the capacity to include sediment mixtures, simulate sediment deposition, and track textural changes in substrate stratigraphy that result from varying flow characteristics. To address this limitation, we developed, implemented, and tested RiverBedDynamics, a new Landlab component that simulates the evolution of bed surface elevation and grain size distribution in two-dimensional grids based on the Exner equation for sediment mass balance. By dynamically coupling RiverBedDynamics with Landlab's hydrodynamic flow solver, OverlandFlow, we created a new LEM capable of simulating the dynamics of local shear stresses, bed load transport rates, and grain size distributions. Comparisons of our LEM results with analytical and previously reported solutions demonstrate its ability to accurately predict time-varying local changes in bed surface elevation, including erosion and deposition, as well as grain size distribution. Furthermore, application of our LEM to a synthetic watershed illustrates how spatially variable rainfall intensity leads to varying discharge patterns, which in turn drive changes in bed elevation and grain size distribution across the domain. This approach provides a more comprehensive representation of the complex interactions between flow dynamics and sediment transport in gravel-bedded rivers, enhancing our ability to model landscape evolution across diverse geomorphic settings.
Processes and controls of regional floods over eastern China

Published: November 2024

Abstract. Mounting evidence points to elevated regional flood hazards in a changing climate, but existing knowledge about their processes and controls is limited. This is partially attributed to inadequate characterizations of the spatial extent and potential drivers of these floods. Here we develop a machine-learning-based framework (mainly including the Density Based Spatial Clustering Applications with Noise (DBSCAN) clustering algorithm and a conditional random forest model) to examine the processes and controls of regional floods over eastern China. Our empirical analyses are based on a dense network of stream gauging stations with continuous observations of annual maximum flood peaks (i.e. magnitude and timing) during the period 1980–2017. A comprehensive catalogue of 318 regional floods is developed. We reveal a pronounced clustering of regional floods in both space and time over eastern China. This is dictated by cyclonic precipitating systems and/or their interactions with topography. We highlight contrasting behaviours of regional floods in terms of their spatial extents and intensities. These contrasts are determined by fine-scale structures of flood-producing storms and anomalous soil moisture. While land surface properties might play a role in basin-scale flood processes, it is more critical to capture spatial–temporal rainfall variabilities and soil moisture anomalies for reliable large-scale flood hazard modelling and impact assessments. Our analyses contribute to flood science by better characterizing the spatial dimension of flood hazards and can serve as a basis for collaborative flood risk management in a changing climate.
A framework for automated supraglacial lake detection and depth retrieval in ICESat-2 photon data across the Greenland and Antarctic ice sheets
Authors: Arndt Philipp Sebastian , Fricker Helen Amanda
Published: November 2024

Abstract. Water depths of supraglacial lakes on the ice sheets are difficult to monitor continuously due the lakes' ephemeral nature and inaccessible locations. Supraglacial lakes have been linked to ice shelf collapse in Antarctica and accelerated flow of grounded ice in Greenland. However, the impact of supraglacial lakes on ice dynamics has not been quantified accurately enough to predict their contribution to future mass loss and sea level rise. This is largely because ice-sheet-wide assessments of meltwater volumes rely on models that are poorly constrained due to a lack of accurate depth measurements. Various recent case studies have demonstrated that accurate supraglacial lake depths can be obtained from NASA's Ice, Cloud and land Elevation Satellite (ICESat-2) ATL03 photon-level data product. ATL03 comprises hundreds of terabytes of unstructured point cloud data, which has made it challenging to use this bathymetric capability at scale. Here, we present two new algorithms – Flat Lake and Underlying Ice Detection (FLUID) and Surface Removal and Robust Fit (SuRRF) – which together provide a fully automated and scalable method for lake detection and along-track depth determination from ATL03 data and establish a framework for its large-scale implementation using distributed high-throughput computing. We report FLUID–SuRRF algorithm performance over two regions known to have significant surface melt – central West Greenland and the Amery Ice Shelf catchment in East Antarctica – during two melt seasons. FLUID–SuRRF reveals a total of 1249 ICESat-2 lake segments up to 25 m deep, with more water during higher-melt years. In the absence of ground-truth data, manual annotation of test data suggests that our method reliably detects melt lakes along ICESat-2's ground tracks whenever the lake bed is visible or partially visible and estimates water depths with a mean absolute error <0.27 m. These results imply that our proposed framework has the potential to generate a comprehensive data product of accurate meltwater depths across both ice sheets.

Creating the opportunity for scholars, practitioners, policy makers, activists or any other group of authors to publish in our journal without having to wait for a thematic Special Issue on a theme that would fit their topic felt like the logical next step in (the continued) continuing professionalization of the Docomomo Journal.In the plan of action for the candidacy of Delft University of Technology as the new headquarters for Docomomo International – presented in 2021 – open access to the journal and expansion of its reach was advocated:“In addition, Docomomo International aims to involve the Docomomo network more actively into the production of content – in particular linked with the new biannual conferences, seminars and workshops related to digitization, education and sustainability. This will strengthen the role of the Docomomo Journal as a link between Docomomo members, the Docomomo chapters to serve the Docomomo network, and its impacts on professional practices and the general public.”The Open Issue aims for contributions that do not fit within the topic of the thematic Special Issues but fit the overall scope of the Docomomo Journal. All contributions to this open issue have had the same peer reviewing process, but instead of organized by guest editors, now under the wings of the editors-in-chief. The 2024 Open Issue features articles on the Lagoa Rowing Stadium in Rio de Janeiro, industrial heritage in Egypt and Iran, on Erik Gunnar Asplund’s Stockholm public library, the transformation of a former hospital to a criminal justice complex in São Paulo, and the House of Manoel Coelho in Curitiba.The creation of a yearly Open Issue in addition to the two regular thematic Special Issues is the next step in the evolution of the Docomomo Journal, that once started as a simple Newsletter and evolved into an academic peer-reviewed and indexed journal (figure 1). The first Newsletter was published in 1989 and changed into a Journal in 1993 (no. 9). Starting with no. 28 in 2003 the lay-out and graphics of the Docomomo Journal changed tremendously, marking the transition into a more academic oriented journal. Another change in graphics took place in 2010, starting with no. 42 and Ana Tostões and Ivan Blasi as editors, also marking the move towards online publication of the individual articles in the Docomomo Journal. In 2022, with the special issue on Modern Plastic Heritage (no. 66) a new lay-out and publication scheme was adopted to accommodate fast online and open access publication of new issues of the journal and its individual articles.The 2024 Open Issue (no. 71) marks the newest development and we call upon the Docomomo Community to continue using, referencing and contributing to the Docomomo Journal, not only to the thematic Special Issues, but also to the Open Issues.

The features of the Kazakh sign language are considered, focusing on the principles of building connections between objects and subjects. The authors highlight spatial and subject- object relationships in sign language, providing examples of their use. It is argued that for effective sign language interpreting it is important to consider visual aspects such as frames and stage, which is accompanied by empirical recommendations for sign language interpreters. Additionally, the issues of classification of gestures by parts of speech and the problems of translation from text to sign language are discussed. A 3D avatar associated with a database of Kazakh words for automated sign language interpretation is described. The authors highlight its role in improving the working conditions of sign language interpreters and providing support for deaf people in social environments.

This work is devoted to the analysis of the surface contact of teeth of cylindrical gears based on machine learning methods. During the study, various machine learning algorithms were used to analyze the influence of the angular displacement of the gears in the gearbox on the quality of the surface contact of the teeth. The work analyzed the influence of such parameters as the shape of the teeth, the modification of the surface of the teeth, the offset angle and other factors on the quality of the surface contact of the teeth. A model of machine learning was developed, which allowed to predict the quality of the contact of the teeth based on the data on the parameters of the gears. The obtained results allow to optimization of the production parameters of cylindrical gears to achieve the best quality of the surface contact of the teeth and increase the efficiency of the mechanisms in which they are used.
Transformasi Pembelajaran Fikih melalui Kurikulum Merdeka Belajar

Published: November 2024

This study aims to investigate a discussion on the implementation of the independent learning curriculum at madrasah tsanawiyah. This research uses a qualitative descriptive qualitative research method using the independent curriculum theory which is based on constructivism learning theory. According to the principle of independent learning, curricula can be tailored to meet the needs and abilities of students, enabling them to participate more actively and creatively in the learning process. Regarding data collection techniques, it consists of conducting interviews with fikih subject teachers. Based on the research, the independent curriculum for learning fikih at MTs Hasyim Asy'ari Bangsri has been implemented since the 2023/2024 school year, but the implementation has not been perfect. When the autonomous learning curriculum for fikih learning was implemented, a number of difficulties and issues were discovered, namely educators or teachers have the responsibility of compiling teaching modules for learning, but the teacher has not found specific reference material for making teaching modules. Information is still limited regarding fikih learning in the independent learning curriculum. Even though the ministry of religion has an independent curriculum platform called Sikurma, the Ministry of Religious Affairs' autonomous learning curriculum which includes learning fikih, has not been fully covered by this platform. Because there aren't many independent curriculum textbooks available for Islamic Religious Education in madrasahs, pupils are still using the 2013 curriculum books.

Image Retrieval has become popular and crucial task and the number of digital images on (web servers) amplified, it became increasingly very difficult to classify and track images. Many methods have been used to make image exploration effective and reliable, such as search based on the file name, image tagging, etc. but none have proved a good idea to work in real scenario. Our proposed methodology applies deep learning using spatial distances, normalized coordinates, scaling and visual words for large data sets for retrieval of images with highest accuracy. The proposed methodology has three basic steps: the first is Content Analysis. The image is passed through coarser intervolving phase, second is CNN, third is RGB color evaluation, fourth is Retrieved feature vectors and fifth is results derivation. Proposed methodology was applied on the three famous datasets namely, Cifar-100, FTVL and Fashion. Experiments conducted on these datasets have shown outstanding results.
On Weighted Sums of Horadam Numbers
Authors: Prabha Sivaraman Nair
Published: November 2024

For nonzero integers p,q with p-q≠1, let (U_n )_(n≥0) be the Lucas sequence of the first kind defined by U_n=pU_(n-1)-qU_(n-2) for n≥2 with initial terms U_0=0 and U_1=1. In this paper, we provide explicit formulas for evaluating the weighted sums ∑_(k=1)^n▒k^m  U_k and ∑_(k=1)^n▒k^m  U_(k+r) using binomial coefficients for nonnegative integers m and arbitrary integers r. Furthermore, we extend these summation formulas to the Horadam sequence (W_n )_(n≥0) defined by the same recursion W_n=pW_(n-1)-qW_(n-2) for n≥2 with arbitrary initial terms W_0 and W_1.
Investigation of Thin Film Flow on a Stretching Cylinder in Unsteady Motion with variable Heat Source/Sink
Authors: Pradeep G. Janthe
Published: November 2024

In this study, we explore the effects of momentum and heat transfer in a thin liquid film over a cylinder that is stretched and undergoes unsteady motion, with the impact of a magnetic field and a non-uniform heat source/sink. Through the use of similarity transformations, the complex system of PDEs (Partial differential equations) is transformed into the ODEs (Ordinary differential equations). This process involves manipulating the equations in such a way that they can be simplified into a set of ODEs, which are typically easier to solve and analyze. By applying these transformations, the system becomes more manageable and can be studied more effectively. Using the bvp4c function in MATLAB which was provided a powerful tool for solving boundary value problems (BVPs) efficiently, particularly when dealing with systems of ODEs. This function utilizes a robust algorithm to numerically solve the ODE system while considering the specified boundary conditions. Graphs are frequently utilized to visually illustrate the effects of different parameters on temperature and velocity profiles in the presence of a variable heat source/sink and an external magnetic field. When the magnetic parameter increases, we observe that the decrease in the velocity profile and film thickness of the fluid and also Heat source\sink parameters lead to fluid temperature enrichment.
