FROM THE TABANAN DISTRICT, BALI ISLAND, INDONESIA2024-10-17T14:49:42+07:00Farid Kuswantorofari013@brin.go.id<p><em>Eugenia uniflora </em>is an exotic fruit species with significant health benefits and considerable ornamental potential. Although substantial research has been conducted on <em>E. uniflora</em> germination, there remains a need for further study on this species’ generative propagation to address unexplored aspects of its reproductive processes. Thus, this study aims to describe <em>E. uniflora</em> germination and seedling biology and the impact of tree and ground fruit seeds on the germination and seedling parameters of the plant species from the Indonesian population. This study employs a completely randomised design of three replications for its germination and seedling parameters trial. Germination parameters, including final germination percentage (FGP), time for 10% (T10), 50% (T50), and 90% (T90) seed germination, and infected seed percentage, were calculated along with seedling parameters such as mean shoot length (MSL), mean root length (MRL), mean total length (MTL), vigour index, and growth index. Quantitative analysis followed by student’s statistical analysis was conducted for these parameters. Descriptive analysis was also performed to study the <em>E. uniflora</em> germination process, germination type, and seedling functional type. This study shows that <em>E. uniflora</em> has hypogeal germination. Cryptocotylar, hypogeal, and reserve storage seedling functional types were observed. Seed harvested from tree and ground fruit does not exhibit significant differences in all germination and seedling parameters. However, this study found that seed infection was also present in ground fruit seeds. The results of this study fill knowledge gaps that support the sustainable use of <em>E. uniflora</em>.</p>2025-01-29T00:00:00+07:00Copyright (c) 2025 Suranaree Journal of Science and Technologyhttps://ph04.tci-thaijo.org/index.php/SUJST/article/view/4451PRIORITIZING FLOOD-PRONE AREAS IN WARNA BASIN, INDIA WITH ANALYTIC HIERARCHY PROCESS2024-09-17T10:14:54+07:00Suraj Kalgonda Patilpatilsuru@gmail.comJagdish Subhash Lambejagdish.lambe@jjmcoe.ac.inDeshbhushan Savindra Patildeshbhushanpatilp@gmail.com<p>Flood events present intricate challenges at the intersection of human necessities and hydrological research, demanding innovative methodologies for hazard assessment and mitigation. This investigation delves into the considerable environmental threat posed by floods in the tropical, moisture-laden landscapes of the Western Ghats within the Swarna watershed, India. Employing advanced methodologies such as the Analytical Hierarchy Process (AHP) integrated within a Geographic Information System (GIS), the study endeavors to formulate a flash flood susceptibility index tailored to the Swarna watershed. Through a comprehensive approach merging remote sensing, GIS, and AHP, the research assesses eleven flood risk parameters to generate thematic maps and prioritize areas most susceptible to flash floods. Results unveil varying degrees of flash flood risk, with a notable concentration of moderate to high-risk zones identified within the Yennehole catchment area. Furthermore, validation of the Flash Flood Magnitude Index (FFMI) underscores the gravity of flash flood hazards within the Yennehole catchment, posing significant threats to assets, infrastructure, and human lives amidst these sudden-onset events. This study enhances the accessibility and resilience of water resources while contributing to the formulation of effective land use planning and flood risk mitigation strategies. The validation of identified hazard zones enhances their reliability and utility in flood control scenarios, showcasing the efficacy of interdisciplinary research in addressing pressing water-related challenges and advancing the objectives of Sustainable Water Resources Management.</p>2025-01-27T00:00:00+07:00Copyright (c) 2025 Suranaree Journal of Science and Technologyhttps://ph04.tci-thaijo.org/index.php/SUJST/article/view/5278INFLUENCE OF TRAFFIC AND VEHICULAR CHARACTERISTICS ON LATER SHIFT OF VEHICLES UNDER VARYING ROADWAY AND GEOMETRIC CONDITIONS 2024-10-28T10:42:16+07:00Ramireddy Sushmithasusmitharamireddy@gmail.comjithender jatothjatoth.jithender@gmail.comAnoop Rajanoopraj@gmail.comKVR RAVISHANKARravikvr@gmail.com<p>The present study is carried out to analyze the lateral shift of different vehicle types while traversing on a horizontal curve with influence of geometrical elements and average speed of the traffic stream. Four different curves with varying radius of curvature and deflection angles were selected in Warangal city. Different vehicle categories were considered such as two-wheeler, car, and three-wheeler to analyze the lateral shifts in the field. The results of the study showed that two wheelers were more affected by the average speed of the traffic, whereas for cars, the overall width of the road at curve was found to be more significant. Difference of operating speed was found to be more significant for three wheelers. The present research found that the radius of curve, average speed of vehicles and overall width of road at curve were influencing the lateral shifts of vehicles irrespective of the vehicle type and hence these factors can be given more importance during the design of horizontal curve geometry.</p>2025-02-17T00:00:00+07:00Copyright (c) 2025 Suranaree Journal of Science and Technologyhttps://ph04.tci-thaijo.org/index.php/SUJST/article/view/3326ANTI-PROLIFERATIVE AND APOPTOSIS INDUCTION OF HYPTIS SUAVEOLENS (L.)

The total phenolic and total flavonoid contents, as well as the antioxidant properties of HSEE were evaluated using the colorimetric method. Cell proliferation was assessed by alamar blue assay. Nuclear morphology changes were detected by Hoechst 33258 staining, while the DNA laddering pattern was assessed using agarose gel electrophoresis. The cell cycle distribution was assessed using flow cytometry, whereas the apoptosis-related protein changes were investigated by Western blotting analysis. HSEE exhibited radical scavenging activity in various radical systems (FRAP, DPPH, and TBARS). As indicated by DNA fragmentation and cell accumulation in the sub-G1 phase, HSEE displayed anti-proliferation and induced apoptosis in Jurkat cells. In addition, HSEE caused cell cycle arrest in Jurkat cells at the G2/M phase and triggered apoptosis through caspase-dependent pathways. After exposure to HSEE for 24 h, the level of Bcl-2 in Jurkat cells dramatically decreased, while the levels of caspase-9 and Bax significantly increased. Overall, these findings revealed that the anti-proliferative effects of HSEE involved the induction of G2/M phase arrest and the intrinsic apoptotic pathway in Jurkat cell lines.</p>2025-02-06T00:00:00+07:00Copyright (c) 2025 Suranaree Journal of Science and Technologyhttps://ph04.tci-thaijo.org/index.php/SUJST/article/view/5932SOLUTIONS FOR TRANSPORTATION AND MAINTENANCE SCHEDULING NEEDS: A CASE STUDY OF A FUEL DISTRIBUTION COMPANY IN UTTARADIT PROVINCE 2025-01-14T11:36:14+07:00Adul Phuk-inadun999@gmail.com<p style="margin: 0cm; text-align: justify; text-justify: inter-cluster;"><span style="font-size: 10.0pt; font-family: 'Times New Roman',serif;">This research focused on the issue of fuel demand management.

This study aimed to isolate and characterize PGPR for biofertilizer development. Sixteen bacterial strains were isolated from organic compost at the On Nut organic composting plant in Bangkok, Thailand. These isolates were evaluated for plant-growth-promoting (PGP) properties, such as phosphate solubilization and the production of indole-3-acetic acid (IAA), ammonia, and chitinase. Isolates 10, 12, 15, and 18 exhibited PGP properties, with the highest phosphate solubilization. In particular, isolate 12 demonstrated the production of IAA at 0.0478 μg/mL and of gibberellin (GA3) at 0.3193 μg/mL, solubility of phosphate at 11.0119 μg/mL, and the highest percent inhibition of radial growth (PIRG) against <em>Colletotrichum gloeosporioides</em> C1060. In pot experiments, rice (<em>Oryza sativa</em> L. cv. RD47) grown with isolate 12 for 10 days showed statistically significantly increased root dry weight (p ≤ 0.05) compared to the other treatments. 16S rRNA sequence analysis in EzBioCloud revealed that isolate 12 was closely related to <em>Bacillus licheniformis</em>.

Microgrid-integrated virtual power plants (VPPs) offer a promising solution by aggregating diverse energy resources and controllable loads while working as an entity. This study investigates an optimized control strategy for regulating active power within such a system. The proposed hybrid microgrid comprises Solar Photovoltaics (PV), Wind Turbines, Diesel Generators, and controllable loads such as Hybrid Electric Vehicles (HEVs) and Heat Pumps. Utilising a Proportional-Integral-Derivative (PID) controller, optimised through the Salp Swarm Algorithm (SSA) and Particle Swarm Optimization (PSO), the study demonstrates improved system stability and response to power fluctuations. Comparative analysis confirms the superiority of the SSA-based control mechanism over the PSO-based approach. This work underscores the robustness and efficiency of the proposed strategy in ensuring stable power management in dynamic microgrid environments.</p>2025-01-29T00:00:00+07:00Copyright (c) 2025 Suranaree Journal of Science and Technologyhttps://ph04.tci-thaijo.org/index.php/SUJST/article/view/5685BIO-INSPIRED PREDICTIVE INSIGHT AND OPTIMIZATION STRATEGY FOR ELECTROMAGNETIC SHIELDING IN HYBRID POLYMER COMPOSITES2024-10-15T14:26:53+07:00Arun Sebastianarunsebastn@cusat.ac.inAsaletha Raghavanasalethar@cusat.ac.in<p>The Machine learning-based EMI shielding effect prediction on polymer composite materials is of supreme importance in modern electronic applications as this shielding serves as a robust protective barrier, safeguarding electronic components from electromagnetic interference. But, capturing the multifactorial nature of the composites and handling multi-objective optimization is still difficult to achieve with the existing machine-learning approaches. Hence, this research proposes a novel “Bio-inspired Predictive Insight and Optimization Strategy” for improving the efficacy of prediction and optimization of the EMI shielding effect of polymer composites. Polymer composites have complex structures with multiple components, leading to nonlinear relationships with EMI shielding effectiveness. This results in a high-dimensional search space, making the search for effective solutions computationally demanding and time-consuming. Here, the “Bayesian-Enriched Genetic Programming” approach captures the multiple parameters such as filler loading, matrix type, and processing conditions effectively to reduce this high-dimensional space complexity. The “Multi-objective Dominant Crowding Seagull (MDCS) optimization” model effectively addresses the challenges of traditional optimization algorithms by optimizing multiple conflicting objectives and EMI shielding. The comparison results show that the proposed method outperforms other methods with a higher prediction accuracy of 98.7%, faster training time of 19 seconds and quicker prediction time of 6 seconds.</p>2025-01-27T00:00:00+07:00Copyright (c) 2025 Suranaree Journal of Science and Technologyhttps://ph04.tci-thaijo.org/index.php/SUJST/article/view/3764A MODIFIED CONTROL SCHEME TO MITIGATE HARMONICS, IMPROVE VOLTAGE REGULATION & POWER FACTOR USING SINGLE-PHASE SHUNT ACTIVE POWER FILTER2024-11-05T08:48:39+07:00Jotirmoy Samantasamanta.jotirmoy@gmail.comRalli Sangnoralli.nitap@gmail.comRajen Pudurrajen.nitap@gmail.com<p>This paper presents a modified control scheme to eliminate various power quality issues using a single-phase shunt active power filter (SAPF). The focus is primarily on harmonics mitigation, power factor (PF) correction, DC link voltage regulation, and reducing the settling time of the system. A nonlinear PID (NLPID) controller is employed to regulate the DC link voltage and reduce the system’s settling time. The overall system is modeled for a 1 kW load and tested under 85% load condition. The results, obtained using the MATLAB/Simulink platform, are found to be quite satisfactory. After compensation, the total harmonic distortion (THD) is reduced to below 8%, in compliance with the IEEE 519-2022 standard, and the PF is improved to nearly unity.</p>2025-01-27T00:00:00+07:00Copyright (c) 2025 Suranaree Journal of Science and Technologyhttps://ph04.tci-thaijo.org/index.php/SUJST/article/view/6027ADVANCED HEFFRON-PHILLIPS MODEL FOR DAMPING OSCILLATIONS BASED ON WALRUS AND ENHANCED SNAKE OPTIMIZATION ALGORITHMS2024-10-15T14:41:37+07:00Niharika Agrawalniharika.svits@gmail.comSheila Mahapatramahapatrasheila@gmail.com<p>A reliable, safe, and secure operation of power systems is essential for all-round development. Low-Frequency Oscillations (LFO) hamper the smooth operation of the system. This manuscript develops an Advanced Heffron-Phillips Model (AHPM) for damping oscillations based on a higher-order Synchronous Machine (SM) Model 1.1. The effectiveness of AHPM is compared for the system without any controller and with Power System Stabilizer (PSS) based on Walrus and Enhanced Snake Optimization Algorithms (ESOA) for three loading conditions. The best damping results are obtained with AHPM, including PSS based on ESOA. The damping ratios (98.60%, 94.50%, and 78.90%) for the three loading conditions obtained with ESOA are higher than with the Walrus algorithm. The settling time, undershoot, and overshoot are also less with ESOA. The simulation is performed with MATLAB R2020. The challenges associated with integrating renewable energy sources into the grid can be met by this AHPM due to better mathematical modelling. By using AHPM with PSS based on ESOA, a robust, secure, and reliable power system is created. Based on four novel strategies, the ESOA tuned the parameters of PSS and produced excellent damping results due to improved performance in terms of speed, accuracy, convergence, and optimization. The simulation can be carried out on multimachine power systems to demonstrate the effectiveness of optimization algorithms. The multi-objective function can be designed for improving stability.</p>2025-01-27T00:00:00+07:00Copyright (c) 2024 Suranaree Journal of Science and Technologyhttps://ph04.tci-thaijo.org/index.php/SUJST/article/view/4701LOW-TEMPERATURE CATALYTIC OXIDATION OF WHITE SPIRIT VAPOR IN AIR BY BINARY OXIDES OF CUO-MNOₓ SUPPORTED ON OMS-2 MATERIAL2024-08-21T15:38:49+07:00Nguyen Nhat Huynnhuy@hcmut.edu.vnNgo Quoc Nguyennqnguyen.sdh222@hcmut.edu.vnHoang Cong Anh Duyhcaduy1310@gmail.comVo Thanh Hanghang_vothanh2003@hcmut.edu.vnNguyen Thi Thuyntthuy@hcmiu.edu.vnVo Thi Thanh Thuyvttthuy@hcmut.edu.vn<p>White spirit is mainly used as a solvent which contains volatile organic compounds (VOCs) that contribute to air pollution and pose health risks.

With the rapid production of next-generation cars, crumb rubber output is expected to rise. Unfortunately, burning and disposing of crumb rubber in landfills harms the environment. This investigation explores the potential use of crumb rubber in concrete, specifically as a fine aggregate. Concrete of M30 grade will be utilized for this study. Future steps involve creating cube, cylinder, and prism specimens, each cast with a unique mix proportion. After a 28-day curing period, these samples will undergo mechanical tests for compressive, flexural, and split tensile strength. Additionally, the density, permeability, and water absorption of CR concrete will be assessed. These findings will determine the optimal crumb rubber content and the overall efficiency of the concrete.</p>2025-01-27T00:00:00+07:00Copyright (c) 2025 Suranaree Journal of Science and Technologyhttps://ph04.tci-thaijo.org/index.php/SUJST/article/view/4047EMBRYOTOXIC AND TERATOGENIC EFFECTS OF MONOSODIUM GLUTAMATE AND SACCHARIN ON WADER (Rasbora lateristriata) FISH2024-10-22T00:00:19+07:00Olvita Mayaniolvitamayani@mail.ugm.ac.idIndah Nur Fauziahindahnurfauziah@mail.ugm.ac.idAnggi Rehulina Sitepuanggirehulinasitepu@mail.ugm.ac.idEben Ezer Simanungkalitebenezersimanungkalit1997@mail.ugm.ac.idDesy Amelia Saputridesyameliasaputri@mail.ugm.ac.idRuth Liananda Citra Dolok Sariburuthlianandacitradoloksaribu@mail.ugm.ac.idAjeng Istyorini Asmoning Dewantiajengistyorini@mail.ugm.ac.idAscarti Adaninggar ascarti.adaninggar@mail.ugm.ac.idRaden Roro Risang Ayu Dewayani Putrirrrisang96@mail.ugm.ac.idAnita Restu Puji Raharjenganitaraharjeng@mail.ugm.ac.idArdaning Nuriliani ardaning@ugm.ac.idBambang Retnoajibambang.retnoaji@ugm.ac.idNur Indah Septrianinurindahseptriani@ugm.ac.idFajar Sofyantorofajar.sofyantoro@ugm.ac.idHendry Saragihsaragihendry@ugm.ac.id<p>The widespread utilization of food additives has garnered increasing attention owing to the safety implications. The continuous reassessment of potential toxicogenic and teratogenic risks associated with food additives is imperative. Monosodium glutamate (MSG) and saccharin, which are prevalently used in the food industry, were the focus of this study. This research aimed to evaluate the effects of MSG, saccharin, and the MSG-saccharin combination on the embryos of wader (<em>Rasbora lateristriata</em>) fish. Observations were conducted at 24, 48, and 72 h postfertilization (hpf) following substance administration. The findings indicated that the MSG- and MSG-saccharin-treated groups exhibited higher incidences of spinal abnormalities, pericardial edema, and bradycardia. Regarding safety, the survival rates of the saccharin-treated groups were higher than those of the MSG- and MSG-saccharin-treated groups. The observations further suggested variations in survival and hatching rates, body pigmentation, and blood clotting. Spinal irregularities, pericardial edema, and bradycardia were the predominant abnormalities recorded.

X-ray diffraction revealed a clear (111) structure for IrMn and NiFe in the as-prepared thin films, whereas the crystal structure of Ru and CoFe underlayers remained undetected due to their limited thickness. Magnetic analysis showed minimal impact on the ferromagnetic underlayer, with a consistent saturation magnetic moment observed. Immersion in detergent solutions resulted in variations in the exchange bias field attributed to increased Mn corrosion within the antiferromagnetic layer. The electrical conductivity of the solution increases with rising detergent concentration, accelerating the corrosion rate of Mn. When the detergent concentration reaches a certain point, the surface-active inhibitor adsorbs onto the IrMn surface with greater surface coverage, leading to a decrease in the corrosion rate. Furthermore, temperature played a crucial role, increasing kinetic energy and accelerating corrosion processes. A comprehensive understanding of these factors is paramount for devising effective corrosion mitigation strategies in thin film manufacturing processes.</p>2025-02-05T00:00:00+07:00Copyright (c) 2025 Suranaree Journal of Science and Technologyhttps://ph04.tci-thaijo.org/index.php/SUJST/article/view/4790META-ANALYSIS OF MICROBIAL DIVERSITY IN YOUNG CATS USING T-BIOINFO SERVER2024-11-04T10:08:47+07:00Umeshkumar KUresearch.umeshkumarku@gmail.comDr. Rekha Karwasradrrekhakarwasra9@gmail.com<p style="margin: 0cm; text-align: justify;"><span style="font-size: 10.0pt; font-family: 'Times New Roman',serif;">The present computational study re-analyzes microbial diversity in young felines using NCBI data to explore site-specific and gender-related patterns.

This species plays a crucial role in pollinating a wide variety of plants and economically important crops. In this study, we examined the genetic diversity and demographic history of <em>A. florea</em> in Thailand using partial sequences of mitochondrial cytochrome c oxidase I (COI) gene. The analysis was conducted using samples from 59 <em>A. florea </em>colonies across Thailand, combined with 13 COI sequences of <em>A. florea</em> from various countries obtained from GenBank. Overall, low nucleotide diversity (0.00321) coupled with high haplotype diversity (0.858) were observed within the Thai populations. The low genetic variation in <em>A. florea</em> suggests that this species occupies a wide range of environments and maintains temporally continuous gene flow, possibly due to its reproductive season. Median-joining network analysis revealed a star-like shape, indicating recent population expansion. This finding was further supported by a unimodal mismatch distribution and significantly negative results for Tajima’s D and Fu’s <em>F</em>s tests. Demographic history analyses suggested that <em>A. florea</em> may have experienced a population expansion approximately 55,000-243,000 years ago.</p>2025-02-20T00:00:00+07:00Copyright (c) 2025 Suranaree Journal of Science and Technologyhttps://ph04.tci-thaijo.org/index.php/SUJST/article/view/4798ABUNDANCE OF POLLUTION-INDICATOR BACTERIA IN CIMANUK WATERS, INDRAMAYU2024-10-15T14:18:05+07:00Nur Fitriah Afiantinurf010@brin.go.idLies Indah Sutiknowatilies004@brin.go.idRisky Ayu Kristantirisky.ayu.kristanti@brin.go.id<p>Cimanuk waters are one of Indonesia’s areas with abundant natural resource potential that have been threatened with contamination due to impulsive population growth and high human activities. Microbiological aspects are one of the parameters that can indicate environmental pollution. Therefore, pollution-indicator bacteria such as coliform and pathogenic bacteria have become one of the most important indicators of environmental conditions. This study conducted an analysis of pollution indicator bacteria at several sampling sites around the Cimanuk estuary to assess the environmental status. Surface seawater (±30 cm) was taken using a Zobell water sampler with <br />a sterile 300 ml bottle. Samples were subjected to microbiological analysis, including total coliform contaminating bacteria, <em>Escherichia coli,</em> heterotrophic bacteria, halotolerant, and pathogenic bacteria. Results showed severe fecal contamination of stations compared to the WHO standards, and total coliforms varied between stations in the range of 1500-3000 CFU/100mL. The presence of pathogenic bacteria such <em>as E. coli, </em>Vibrio cholera, Aeromonas spp., Salmonela spp., and other bacteria indicative of fecal contamination were reported. Coliform bacteria and <em>E. coli </em>were found at the highest density in coastal waters near the mainland, indicating waste input due to anthropogenic activities. This study shows that Cimanuk waters are not good for biota and recreational studies.</p>2025-01-29T00:00:00+07:00Copyright (c) 2025 Suranaree Journal of Science and Technologyhttps://ph04.tci-thaijo.org/index.php/SUJST/article/view/3293QUALITY EVALUATION OF FLOUR AND BISCUIT PRODUCED FROM SWEET POTATO AND ORANGE POMACE2025-01-13T10:42:39+07:00Stephen Arinolaarinola_so@fedpolyado.edu.ngAfolabi Omolara O.omolarakolawole012@gmail.comOkunola Olutayo V.okunolav1@gmail.com<p>This study exploited the food and functional potentials of orange pomace, a solid waste of orange juice production, in producing composite flours and acceptable biscuit. Orange pomace and sweet potato were processed into flour; at 0%, 5%, 10%, 15%, 20%, 25% and 30% levels, orange pomace flour was utilized to substitute sweet potato flour. Using conventional techniques, pasting and functional analysis were performed on the composite flours, likewise the proximate composition, antioxidant activity, physical characteristics and sensory acceptability of biscuits made from the composite flours were assessed. Wheat biscuit served as control. The pasting and functional qualities of the composite flours varied; addition of orange pomace considerably decreased peak viscosity (86.08 - 146.92 RVU) and breakdown viscosity (12.58 - 39.67 RVU) with varying impact on setback viscosity (43.00 - 62.75 RVU) and final viscosity (117.33 - 172.08 RVU). Biscuits produced from the composite flours were found to be significantly denser in ash (3.25 - 4.85%) and crude fibre (4.62 - 11.15%). The inclusion of orange pomace significantly increased DPPH, FRAP and total phenolic content with values ranging from 73. 23 to 83.44%, 4.85 to 9.92 mg vit. C/g and 17.93 to 24.75 mg GAE/g respectively. Biscuit produced from 85% sweet potato and 15% orange pomace composite flour showed significant higher acceptability and it compared favourably with the control. This study demonstrated that sweet potato-orange pomace composite flours could be used to make biscuits that people would find acceptable and that would support the waste-to-wealth drive as well as human fiber intake and its associated health benefits.</p>2025-02-19T00:00:00+07:00Copyright (c) 2025 Suranaree Journal of Science and Technologyhttps://ph04.tci-thaijo.org/index.php/SUJST/article/view/6685THE PROSPECT OF MUOGRAPHIC DETECTION USING PLASTIC SCINTILLATOR IN INDONESIA - A REVIEW2024-12-13T13:37:43+07:00Tanti Ardiyatitanti.ardiyati@gmail.comDian Fitri Atmokodian024@brin.go.idWiranto Budi Santosowira001@brin.go.idHafni Lissa Nurihafn001@brin.go.idAyodya Pradhipta Tenggaraayodya.p.t@ugm.ac.id<p>Muography technology has evolved over the past decade for various observational applications without using radioactive materials. Muography utilizes naturally occurring muons to penetrate objects with thick shielding and pass through kilometers of rock. Detectors are required to generate an image of an object obtained from muon captures. Various studies have created images of magma flow, thus enabling monitoring of active volcanoes, discovering hidden chambers within temple or pyramid structures, and so on. Plastic scintillation detectors are widely used in various muography applications due to their reliability and robustness in various challenging environments, ability to move flexibly, and cost-effectiveness.
