    Nitrocellulose (NC)-based propellants have played a pivotal role in the development of energetic materials for both military and civilian applications. This review offers a comprehensive exploration of NC-based propellants, tracing their evolution from their historical origins as smokeless gunpowder to modern advancements. It discusses the chemical composition and classifications of NC propellants, along with continuous efforts to refine smokeless powder formulations through studies on smoke formation, residues, and additives. Modern techniques such as PCR-based detection and dynamic light scattering have enabled precise analysis of NC properties, including variations in the degree of substitution and molar mass, which allow for tailoring the chemical structure to meet specific performance needs. Special attention is given to the combustion dynamics of NC-based propellants, with an emphasis on reaction zones, performance characteristics, and optimization strategies that enhance their overall efficacy. The review also highlights the significant impact of nitrogen content, additives, and processing methods on the performance, stability, and safety of NC-infused propellants. While higher nitrogen content improves energetic output, it also increases surface cracking and gas production, necessitating the use of stabilizers and additives like Bu-NENA, copper compounds, and MgH2 to enhance flexibility, thermal stability, and reduce sensitivity to mechanical and thermal stimuli. Aging and environmental factors further influence burn rate variation, underscoring the need for tailored formulations. In terms of environmental sustainability, this review addresses safety considerations in handling and disposing of NC-based materials, focusing on innovations such as alkaline hydrolysis and NC recovery to mitigate environmental risks. Stabilizers and eco-friendly additives effectively prevent chemical degradation, reduce shock sensitivity, and enhance thermal stability. The review concludes with future research directions aimed at further improving the stability and safety of NC-based propellants, ensuring their continued relevance in modern applications.

    Elevated concentrations of pharmaceutically active compounds (PhACs) in the water bodies are posing a serious threat to the aquatic microbiota and other organisms. In this context, anaerobic ammonium oxidizing (anammox) bacteria carry a great potential to degrade PhACs through their innate metabolic pathways. This study investigates the influence of short-term exposure to lower and higher concentrations (0.8 mg L-1, 0.06 mg L-1, respectively) of antibiotics on the anammox process under distinct operational conditions (starvation/non-starvation) in moving bed biofilm reactor (MBBR). During batch operations that lasted for up to 6 h, the total nitrogen removal efficiency (TNRE) and total nitrogen conversion rate (TNCR) reached a maximum of 93 ± 5 % and 6.97 ± 1.30 mg N g-1 TSS d-1, respectively. Evidently, at higher PhAC levels, the anammox process was active, and up to 75 % PhAC removal efficiency was obtained within 6 h of the batch cycle. Most importantly, the anammox biofilm effectively eliminated the PhACs compounds, i.e., ciprofloxacin (CIP), ofloxacin (OFL), and norfloxacin (NOR) present at higher (0.8 mg L-1) and lower (0.06 mg L-1) total PhACs (sum of CIP, NOR, OFL) concentrations. Furthermore, 16S rRNA sequencing analyses showed a mixture of nitrifying, denitrifying, and anammox bacterial commodities enriched on the carriers' surface with a high relative abundance of Candidatus Brocadia, primarily responsible for catalyzing the anammox process. This study showed the intricate relationship between PhAC concentrations, TNCR, and antibiotic elimination in the wastewater treatment, and the results obtained set up a new breakthrough in wastewater treatment. Future research should investigate the mechanisms that underlie the anammox biofilms' resistance to various types of PhACs and investigate the long-term stability and scalability of this process with real wastewater influents.

    PURPOSE: To highlight a case report of high-grade primary lacrimal sac Burkitt lymphoma in a young adult.

    OBSERVATION: A 25-year-old gentleman was referred to the oculoplastic center for left eye medial canthal progressive swelling at the level below the medial canthal tendon for two months associated with tearing. He was initially treated for preseptal cellulitis but failed to respond to antibiotics. Both eyes vision were 6/9, and the ocular examination showed a left medial canthal non-tender, firm mass 2cm by 3 cm in size, immobile, smooth surface, and inflamed overlying skin. Otherwise, both anterior segment and fundus examinations were unremarkable. Contrasted CT orbit revealed a 3cm enhanced lesion around the lacrimal system region with extension into the middle nasal hiatus and maxillary bone destruction. Left incisional biopsy and tumor debulking were done. Intraoperative findings were a whitish, firm mass with bony destruction at the left maxillary bone. Histopathological examination showed high-grade B cell lymphoma and areas of starry-sky appearance. Immunological markers (CD20, CD79a, CD10, MUM1, BCL6, and BCL2) were positive. Left nasolacrimal sac Burkitt lymphoma diagnosis was made, and CT-thorax-abdomen-pelvis reported no distant metastasis. The patient was referred to a haemato-oncologist and completed six cycles of R-block chemotherapy. The patient is currently in complete remission at six months.

    CONCLUSIONS AND IMPORTANCE: Lacrimal sac Burkitt lymphoma can occur in young, healthy adults; however, a high index of suspicion is mandatory in young patients with preseptal cellulitis associated with medial canthal swelling and recurrent acute dacryocystitis.

    This study explores the possibility of integrating and retrieving heterogenous data across platforms by using ontology graph databases to enhance educational insights and enabling advanced data-driven decision-making. Motivated by some of the well-known universities and other Higher Education Institutions ontology, this study improvises the existing entities and introduces new entities in order to tackle a new topic identified from the preliminary interview conducted in the study to cover the study objective. The paper also proposes an innovative ontology, referred to as Student Performance and Course, to enhance resource management and evaluation mechanisms on course, students, and MOOC performance by the faculty. The model solves the issues of data accumulation and their heterogeneity, including the problem of having data in different formats and various semantic similarities, and is suitable for processing large amounts of data in terms of scalability. Thus, it also offers a way to confirm the process of data retrieval that is based on performance assessment with the help of an evaluation matrix.

    The surge in plastic production has spurred a global crisis as plastic pollution intensifies, with microplastics and nanoplastics emerging as notable environmental threats. Due to their miniature size, these particles are ubiquitous across ecosystems and pose severe hazards as they are ingested and bioaccumulate within organisms. Although global plastic production has reached an alarming 400.3 MTs, recycling efforts remain limited, with only 18.5 MTs being recycled. Currently, out of the total plastic waste, 49.6 % is converted into energy, 27 % is recycled, and 23.5 % is recovered as material, indicating a need for better waste management practices to combat the escalating pollution levels. Research studies on micro-nanoplastics have primarily concentrated on their environmental presence and laboratory-based toxicity studies. This review critically examines the sources and detection methods for micro-nanoplastics, emphasising their toxicological effects and ecological impacts. Organisms like zebrafish and rats serve as key models for studying these particle's bioaccumulative potential, showcasing adverse effects that extend to DNA damage, oxidative stress, and cellular apoptosis. Studies reveal that micro-nanoplastics can permeate biological barriers, including the blood-brain barrier, neurological imbalance, cardiac, respiratory, and dermatological disorders. These health risks, particularly relevant for humans, underscore the urgency for broader, real-world studies beyond controlled laboratory conditions. Additionally, the review discusses innovative energy-harvesting technologies as sustainable alternatives for plastic waste utilisation, particularly valuable for energy-deficient regions. These strategies aim to simultaneously address energy demands and mitigate plastic waste. This approach aligns with global sustainability goals, providing a promising avenue for both pollution reduction and energy generation. The review calls for further research to enhance detection techniques, assess long-term environmental impacts, and explore sustainable solutions that integrate energy recovery with pollution mitigation, especially in regions most affected by both energy shortages and increased plastic waste.

    BACKGROUND: Oxidative stress is strongly linked to neurodegeneration through the activation of c-Abl kinase, which arrests α-synuclein proteolysis by interacting with parkin interacting substrate (PARIS) and aminoacyl tRNA synthetase complex-interacting multifunctional protein 2 (AIMP2). This activation, triggered by ataxia-telangiectasia mutated (ATM) kinase, leads to dopaminergic neuron loss and α-synuclein aggregation, a critical pathophysiological aspect of Parkinson's disease (PD). To halt PD progression, pharmacological inhibition of c-Abl kinase is essential. Despite three generations of tyrosine kinase inhibitors (TKIs) being explored for PD treatment, they present significant concerns including poor blood-brain barrier penetration, off-target effects, and severe side effects. Notably, there are currently no FDA-approved c-Abl kinase inhibitors in clinical usage for PD treatment, highlighting the urgent need for potent, safe, and cost-effective alternatives.

    OBJECTIVE: This study aims to identify potential c-Abl kinase inhibitors from plant-derived compounds with reported anti-Parkinson's potential and their derivatives using molecular docking, molecular dynamics simulations (MDS), and in silico pharmacokinetics and toxicity profiling.

    METHODS: Seventy-eight compounds sourced from literature were docked against c-Abl kinase using Maestro 12.5. The top three hit compounds, along with nilotinib (control drug), were subjected to drug-likeness, ADMET profiling using the AI Drug Lab server and 100 ns MDS using Desmond.

    RESULTS: Amburoside A, diarylheptanoid MS13, and dimethylaminomethyl-substituted-curcumin showed binding affinities close to nilotinib, with values of -12.615, -12.556, and -11.895 kcal/mol respectively, compared to nilotinib's -16.826 kcal/mol. The three plant-derived compounds exhibited excellent structural stability and favorable ADMET profiles, including optimal blood-brain barrier permeation Conclusion: The three hit compounds identified in this study show potential as c-Abl kinase inhibitors. Given the absence of FDA-approved c-Abl kinase inhibitors for PD, these findings are significant as they could contribute new therapeutic options for the treatment and management of PD. However, further in vitro and in vivo experiments are necessary to validate these findings.

    AIM(S): To determine the prevalence of medication administration errors and identify factors associated with medication administration errors among neonates in the neonatal intensive care units.

    DESIGN: Prospective direct observational study.

    METHODS: The study was conducted in the neonatal intensive care units of five public hospitals in Malaysia from April 2022 to March 2023. The preparation and administration of medications were observed using a standardized data collection form followed by chart review. After data collection, error identification was independently performed by two clinical pharmacists. Multivariable logistic regression was used to identify factors associated with medication administration errors.

    RESULTS: A total of 743 out of 1093 observed doses had at least one error, affecting 92.4% (157/170) neonates. The rate of medication administration errors was 68.0%. The top three most frequently occurring types of medication administration errors were wrong rate of administration (21.2%), wrong drug preparation (17.9%) and wrong dose (17.0%). Factors significantly associated with medication administration errors were medications administered intravenously, unavailability of a protocol, the number of prescribed medications, nursing experience, non-ventilated neonates and gestational age in weeks.

    CONCLUSION: Medication administration errors among neonates in the neonatal intensive care units are still common. The intravenous route of administration, absence of a protocol, younger gestational age, non-ventilated neonates, higher number of medications prescribed and increased years of nursing experience were significantly associated with medication administration errors.

    IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: The findings of this study will enable the implementation of effective and sustainable interventions to target the factors identified in reducing medication administration errors among neonates in the neonatal intensive care unit.

    REPORTING METHOD: We adhered to the STROBE checklist.

    PATIENT OR PUBLIC CONTRIBUTION: An expert panel consisting of healthcare professionals was involved in the identification of independent variables.

    BACKGROUND: The use of robotic-assisted surgery (RAS) is growing rapidly. However, economic evaluation of this technology is challenging. This study aims to identify and discuss the different economic evaluation methods which have been used to evaluate RAS.

    METHOD: This scoping review systematically searched PubMed and Embase from 2015 to 2023. We included economic evaluation studies comparing RAS versus laparoscopic or open surgery. The Consolidated Health Economic Evaluation Reporting Standards (CHEERS) checklist was used to aid data extraction and was extended to cover additional features relevant to RAS, including learning curve, organisational impact, incremental innovation and dynamic pricing.

    RESULTS: A total of 50 economic evaluations of RAS were included. Cost-utility analysis (46%) was the most commonly applied economic evaluation method, followed by cost-consequence analysis (32%). The studies focused on the specialties of urology (42%), hepato-pancreato-biliary (20%), colorectal (14%) and gynaecology (6%). Distinctive features related to the assessment of RAS were under-addressed in economic evaluations. Only 40% of the included studies considered learning curve and organisational impact and less than 12% of the included studies reflected on incremental innovation and dynamic pricing.

    CONCLUSIONS: This review found that some studies have incorporated challenges specific to RAS in their evaluations. However, most studies still lack key aspects of importance. In particular, studies rarely considered the ability of RAS platforms to be shared across multiple specialities. Incorporating these distinctive features offers an opportunity for economic evaluation to provide decision-makers with a more realistic assessment of the cost-effectiveness of this technology and to ensure its optimal utilisation in clinical practice.

    OBJECTIVE: This study aimed to analyse the impact of sociodemographic factors on dental school candidates' decision to pursue dentistry as their career of choice.

    MATERIALS AND METHODS: Candidates shortlisted by three dental schools were invited to participate in a self-administered questionnaire study, featuring a validated instrument containing sociodemographic questions and 16 motivational items grouped into four domains: economic, professional, vocational and personal background reasons. The variations in motivational item scores across sociodemographic factors were assessed using the Mann-Whitney U test (age, sex, ethnicity, having relatives in the dental profession and dentistry as the first choice) and Kruskal-Wallis test (dental school and family income).

    RESULTS: A total of 295 dental school candidates participated in the study (Universiti Teknologi MARA: 137; Universiti Kebangsaan Malaysia: 99; MAHSA University: 59). Approximately 95% of participants identified dentistry as their primary career choice, with the vocational motivation of 'I like to help people' being the most prominent motivational factor. Dental school emerged as the critical factor significantly influencing three quarters of the motivational items. Sex, ethnicity and having relatives in the dental profession were the remaining factors significantly associated with variations in certain motivational items. Both dental school and ethnicity significantly affected four motivational domains (economic, professional, vocational and personal background).

    CONCLUSION: This study provides an insightful overview of the sociodemographic factors that impact career decision-making among prospective dental students. The scores for most motivational items varied among shortlisted candidates in three dental schools. The findings hold implications for policy development in dentistry by universities and public policymakers.

    INTRODUCTION: Hemodialysis is frequently used as a primary treatment for individuals with end-stage kidney disease (ESKD), and it significantly impacts the quality of life in adolescents undergoing this procedure. Providing a hemodialysis education to these patients is a valuable strategy for enhancing their well-being. The aim of the study is to assess the effect of the video-assisted educational program on the quality of life among adolescents undergoing hemodialysis in Palestine.

    METHODS: This study employed a quasi-experimental design, a pre-test-post-test interventional study, involving a sample of 68 adolescent patients between the ages of 13 and 18 diagnosed with ESKD. The quality of life level was assessed in both groups using an Arabic version of the Pediatric Quality of Life Inventory™ version 3.0 ESKD Module survey. The study was conducted at the dialysis units in four hospitals associated with Augusta Victoria Hospital, An-Najah University Hospital, Palestine Medical Complex/Ramallah, and Beit Jala (Al Housain) Hospital. The study involved providing tailored face-to-face educational sessions with video assistance to the experimental group, while the control group received regular face-to-face education.

    FINDINGS: The Generalized Estimating Equation analysis revealed no significant differences in quality of life between the experimental and control groups over time, across pre-test, post-test, and follow-up periods (p ≥ 0.05). However, within the experimental group, there was a significant improvement in total quality of life scores between the pre-test, post-test, and post-test follow-up (p ≤ 0.001), although the difference between the pre-test and follow-up approached significance but was not statistically significant (p = 0.056). In contrast, the control group showed significant differences in quality of life across the pre-test, post-test, and follow-up time points (p ≤ 0.05).

    DISCUSSION: Implementing suitable interventions can potentially enhance the quality of life for individuals undergoing hemodialysis. Consequently, we suggest using video-based education as a cost-effective, uncomplicated, and engaging approach for educating hemodialysis patients.

    BACKGROUND: Kenaf seeds are a rich source of protein; however, finding the best extraction method is crucial to obtaining high-quality protein from these underutilized seeds. This research devised an optimized extraction process for best recovery of kenaf seeds protein using response surface methodology. The key parameters affecting the yield and protein content were optimized, including extraction pH (2-11), seed:water ratio (5:1-50:1), temperature (30-90 °C), and duration (20-360 min). The physicochemical and techno-functional properties of kenaf seed protein isolates (KSPIs) were examined.

    RESULTS: A maximum protein yield of 12.05 g/100 g with purity level 91.94 g/100 g was obtained using an optimized extraction with pH 11.0, seed:water ratio 50:1, 360 min duration, and temperature 50 °C. The oil and water retention capacities of KSPI were 1.14 mL g-1 and 1.37 mL g-1 respectively. After 30 min at pH 7, KSPIs demonstrated remarkable emulsion capacity (83.12%) and stability (75.63%), along with high foaming capacity (106%) and stability (18.3%). As per high-performance liquid chromatography analysis, arginine, glutamic acid, leucine, phenylalanine, and lysine were the most abundant amino acids detected in KPSIs. The KSPIs' globular protein structure was successfully verified using analytical approaches, including Fourier transform infrared spectroscopy, protein fraction ratios, and differential scanning calorimetry. Sodium dodecyl sulfate polyacrylamide gel electrophoresis analysis revealed that KPSI has a molecular weight distribution ranging from 10 kDa to 50 kDa.

    CONCLUSION: The results of this study support the application of the proposed response-surface-methodology-optimized extraction method for efficient recovery of high-quality kenaf seed proteins that meet the necessary physicochemical and techno-functional requirements. © 2024 Society of Chemical Industry.

    The treatment of biodegradable plastics through composting has garnered increasing attention. This study aimed to investigate the effects of Biochar FN1 bacteria and ferrous sulfate on nitrogen retention, greenhouse gas emissions, and degradable plastics during composting and to elucidate their synergistic mechanisms on microbial communities. Compared with the control, applying biochar-loaded FN1 bacteria composites combined with Ferrous sulfate (SGC) markedly accelerated organic matter degradation and reduced cumulative CO2 and NH3 emissions. The synergistic interaction between the composites and Ferrous sulfate significantly enhanced NH4+-N levels in the thermophilic phase and NO3--N levels in the cooling phase, ultimately decreasing nitrogen loss by 14.9% (P

    INTRODUCTION: Transvaginal natural orifice specimen extraction surgery (NOSES) is an innovative and feasible approach for left-sided colorectal resections in females. This study aimed to report our experience with transvaginal NOSES for left-sided laparoscopic colorectal resections.

    PATIENTS AND METHODS: We analysed data for all patients with transvaginal extraction performed for left-sided laparoscopic colorectal resections between 2011 and 2021 at a tertiary teaching hospital in Taiwan.

    RESULTS: The 18 post-menopausal patients were of a mean age of 69.2 ± 10.14 years. The lesions were located at the descending ( n = 5), sigmoid colon ( n = 12) and rectum ( n = 1). The operative time was 262.5 ± 83.91 min, and the blood loss was 34 ± 35.98 mL. All patients had an end-to-end anastomosis, and the anastomotic height was 15.06 ± 8.57 cm. Two patients received diversion stoma. The mean length of hospital stay was 5.1 days (standard deviation ± 2.42; range: 3-12 days). There were no cases of clinical infection. The pathology was malignancy ( n = 14, 77.8%), diverticulitis ( n = 2, 11.2%) and benign ( n = 2, 11.2%). In cancers, they were Stage I ( n = 1, 7.1%), IIa ( n = 1, 7.1%), IIIb ( n = 15, 78.7%) and IV ( n = 1, 7.1%). Malignant specimens ( n = 14) were mostly moderately differentiated ( n = 11, 78.6%), with two poorly differentiated (14.3%) and one well-differentiated (7.1%). The lymph nodes harvested were 16.1 ± 8.11. The widest dimension of the lesion was 3.43 cm ± 1.28 (range: 1.5-6) and the length of the specimen was 14.69 cm ± 5.01 (range: 8-27).

    CONCLUSION: Transvaginal NOSES is safe and feasible for left-sided colorectal resection. Factors to consider are the characteristics of the specimen, anal canal and vagina.

    Global warming caused by carbon emissions has become a significant concern for countries worldwide. This study thoroughly examines the spatiotemporal patterns and spatial spillover effects of carbon emissions in China. This research employs kernel density estimation, Moran's index, and the standard deviation ellipse model to analyse the spatiotemporal evolution of carbon emissions in China while utilizing the spatial Durbin model to explore the spatial spillover effects of the digital economy on carbon emissions. The subsequent findings are derived from the following: (1) China's carbon emissions are characterized by substantial spatial and temporal agglomeration. Low carbon emissions are in the eastern littoral regions, while high carbon emissions are concentrated in the inland areas, such as the northwest. The local Moran index suggests that high-high and low-low clustering patterns characterize China's carbon emissions. (2) The spatial trends and evolutionary characteristics of carbon emissions in China are readily apparent. During the sample period, the carbon emission level in the east and west was significantly higher than in the central region, and the gap between the areas was progressively narrowing. The results of the standard deviation ellipse indicate that China's carbon emissions are undergoing a substantial discrete phenomenon in their spatial distribution. (3) Digital economies reduce carbon emissions, have regional spillover effects, and reveal geographical variance across eastern, central, and western regions. This study offers quantitative evidence for integrated nationwide and regional emission reduction and carbon mitigation strategies, as well as for region-specific emission reduction programs.

    The accumulation of plastic waste from various sources into marine and inland water is considered a global problem due to its serious impacts on aquatic ecosystems and human health. In the past decade, remote sensing has played an important role in monitoring of plastic pollution in marine and inland water sources and has achieved a series of research results in this field. In this study, a comprehensive review was conducted on the development, opportunities, and challenges of datasets and methods in Marine and Inland Water Plastics Remote Sensing (MIWPRS) monitoring over the past decade, based on the Web of Science (WOS) core database. The results indicated that compared with traditional methods, remote sensing has attracted the attention of scholars due to its advantages. Since 2014, the number of related publications has been increasing year by year, especially in China and the United States, which have achieved tremendous development. The MIWPRS research focus mostly on the use of different satellite remote sensing data and related algorithms to obtain the distribution of plastics in marine and inland water. However, it faces the challenge of lacking subsequent systematic impact assessment models and key pollution prevention measures. In terms of data acquisition, there is a lack of continuous observation models due to the fluidity of marine and inland water. Therefore, MIWPRS has great development opportunities in developing specialized sensors and combining multi-source data with interdisciplinary knowledge such as artificial intelligence (AI) and GIS. It is necessary for us to improve the seasonal migration model of plastics in water and promote the development of MIWPRS towards broader and deeper fields.

    Nutrient recovery from aquaculture sludge is vital for promoting hydroponic plant growth and achieving near-zero solid waste discharge in aquaponic systems. Modified biological aerated filters (MBAFs) are promising because of the dual capabilities of aquaculture sludge collection and aerobic mineralization. However, the bioconversion kinetics, which is indirectly related to the packed media, need to be improved. In this study, a novel polyhedral hollow sphere (PHS) medium was used in an MBAF (MBAF-PHS) to overcome the shortcomings of the current medium, facilitating fish sludge retention and enhancing subsequent bioconversion kinetics for nutrient recovery. An average rate of 36.9 g/d for dry weight of fish sludge was achieved during 29 d of filtration and an average reduction rate of 31.30 g/d during 26 d of bioconversion. The total mass of fish sludge was converted by 76.2% via the co-action of the solubilization of organic solids and degradation of dissolved organic matter. MBAF-PHS was competitive for macronutrient recovery compared with the MBAF-sponge previously used. The ratios of the final concentrations of the macronutrients (P, Mg, and S) to the concentrations in Hoagland solution (Cf/CH, %) were 278.1, 162.8, and 200.9%, respectively, whereas the ratios of N, K, and Ca were 65.9, 37.1, and 51.0%, respectively. High bioconversion kinetics of NO3--N and PO43--P were obtained within 7 d with an MNO3-N/MTN of 79.9% and MPO4-P/MDTP of 80.3%. The nutrient bioconversion of fish sludge was associated with the diversity of the microbial community in the MBAF-PHS, especially the population of nitrogen-removing microbial species that developed after 9 d of mineralization.

    This study examines the concentration, distribution, and characteristics of suspended microplastics (MPs) across various indoor environments in Malaysia, including offices, classrooms, landed homes, and apartments. Over a six-week period, MPs were collected using a vacuum pump and analyzed through gravimetric analysis, stereomicroscopy, and Raman spectroscopy. The results revealed significant variability in MPs concentrations among different locations, with fibers identified as the predominant morphological type. The average counts of MPs in the respective environments were found to be 599 ± 182 in offices, 399 ± 52 in classrooms, 505.17 ± 203.78 in apartments, and 515 ± 134 in landed homes. Statistical analysis indicated no significant differences in MPs counts across the sampled locations. Fibers were consistently the most prevalent shape, followed by films and foams. The MPs were predominantly transparent, with sizes ranging from 101 to 500 μm. Notably, the estimated daily intake (EDI) of MPs was significantly higher in residential settings compared to offices and classrooms, raising potential health concerns regarding prolonged exposure. These findings underscore the pervasive presence of MPs in the Malaysian indoor environment and emphasize the urgent need for further research to identify their sources, assess health impacts, and develop effective mitigation strategies.

    Phosphate (PO4(III)) contamination in water bodies poses significant environmental challenges, necessitating efficient and accurate methods to predict and optimize its removal. The current study addresses this issue by predicting the adsorption capacity of PO4(III) ions onto biochar-based materials using five probabilistic machine learning models: eXtreme Gradient Boosting LSS (XGBoostLSS), Natural Gradient Boosting, Bayesian Neural Networks (NN), Probabilistic NN, and Monte-Carlo Dropout NN. Utilizing a dataset of 2952 data points with 16 inputs, XGBoostLSS demonstrated the highest R2 (0.95) on new adsorbents. SHapely Additive exPlanations analysis showed that adsorption experimental conditions had the most significant impact (43%), followed by synthesis conditions (29%) and adsorbent characteristics (28%). Optimized conditions included an initial PO4(III) concentration of 125 mg/L, carbon content of 11.5%, oxygen content of 23%, a contact time of 1440 min, a heating rate of 5 °C/min, 200 rpm, and a surface area of 410 m2/g, using Ra-LDO adsorbent synthesized from rape cabbage feedstock. This study developed and presented a practical online framework for predicting PO4(III) removal onto biochar using a web-based graphical user interface.
