The use of strigolactone (SL) analogs as suicidal germination agents to control the seed banks of the parasitic weed Striga hermonthica has gained interest for field applications in recent years. However, concerns about the environmental safety of these SL analogs remain. In this study, we evaluated the mutagenic potential of two selected SL analogs, Methyl Phenlactonoate 3 (MP3) and Nijmegen-1, across concentrations ranging from 1.5 to 5000 μg per plate. We conducted this assessment using five histidine-deficient mutant tester strains of Salmonella typhimurium. After incubating the SL analogs with the tester strains, we observed no significant increase in the number of revertants, with and without the S9 mix, compared to both negative and positive laboratory controls. These results suggest that MP3 and Nijmegen-1 are non-mutagenic according to the bacterial reverse mutation test, supporting their potential as environmentally safe agents for managing Striga populations. © 2024 The Authors

Fusarium wilt, caused by Fusarium oxysporum, is one of the most devastating diseases to crops including potatoes. This fungus is widespread and dispersed via resistant spores. In this study, organic (methanol, hexane, and chloroform) and aqueous extracts of the aerial parts of wild Origanum elongatum were tested against mycelium and spores of F. oxysporum in both in-vitro (using the poisoned food technique) and in-planta assays. Further, the chemical composition of the extract was identified via HPLC-PDA-MS/MS. Then, molecular modeling was used to clarify the antifungal activity of identified biomolecules. The obtained results showed that organic and aqueous extracts showed significant antifungal and anti-sporulation activities with different effectiveness depending on the extract, concentration, and application test. In in-vitro assays of the aqueous extract, the highest antifungal activity was recorded at concentrations of 10 mg mL⁻¹, while the highest anti-sporulation activity (91.79 %) was observed at 50 mg mL⁻¹. In the organic extracts, methanol was the most effective against fungus with 100 % inhibition of mycelium at 5 mg mL ⁻¹ and the highest anti-sporulation effect (73.58 %) at 20 mg mL⁻¹. In in-planta assays, the methanolic extract at 20 mg mL⁻¹ achieved 0 % disease severity, while the aqueous extract at 50 mg mL⁻¹ reduced severity to 7 %, both significantly more effective than the untreated control. Therefore, methanol was the most effective and these biological properties are supported by a wide range of bioactive molecules, including 56 molecules compared to only 28 molecules in the aqueous extract. These include glycosides of apigenin and kaempferol and salvianolic acid b. However, more research is needed to clarify the inhibition action of the individual components and their synergetic actions in controlled and field conditions. © 2024 The Authors

This study proposes a new approach, a communal-based domestic rainwater harvesting (CDRWH) system, which is a new model that combines domestic and communal rainwater harvesting systems. This model is an alternative solution to improve system performance and utilize rainwater overflow from the system. Rainwater runoff from several domestic tanks is channeled to a communal tank to be collected, processed, and redistributed to needy domestic tanks. Overflow from the communal tank is used for groundwater recharge. The CDRWH system model aims to increase water supply, reduce runoff, and conserve groundwater. The model simulation uses daily water balance analysis and yield before spillage algorithm. The simulation scenario uses variations in roof area, number of house occupants, storage tank volume, and rainfall categories: 20 years, wet year, normal year, and dry year. Jagakarsa, an urban area in South Jakarta, was selected for the CDRWH system modeling. The results showed that the CDRWH model significantly improved the performance of the volumetric reliability (VR) and time reliability (TR) systems. In addition, the model could show a comparison of total groundwater recharge (GWR) and groundwater extraction (GWE), where the GWR capacity was higher. This allows centralized rainwater management in communal tanks, thereby reducing groundwater usage. The design of this model is simple. Therefore it can be easily duplicated for application in other locations. © 2025 The Authors

This study reports for the first time the dual kinetics phenomenon triggered by the in situ generated ketone derivatives in the cathode chamber and reveals the mode of catalytic persulfate activation through electron exchange by the conversion of ketone functional groups to ketone derivatives. The experimental results show that the reaction rate constant in the rapid degradation stage in the cathode chamber (42.62 × 10 -2 min −1 ) is significantly higher than that in the induction stage (2.11 × 10 -2 min −1 ), achieving 98.96 % removal within 25 min. The intermediate validation experiments indicate that the in-situ generation of ketone-containing intermediates in the cathode chamber increases the steady-state concentration of reactive species (from 1.71 × 10 -10 to 1.08 × 10 -9 ML -1 ), which is the main reason for the increased reaction rate. The ketone capture experiments and density functional theory (DFT) calculations show that the intermediates with ketone functional groups exchange electrons with persulfate ions under alkaline conditions and in the presence of an electric field, generating additional sulfate radicals and singlet oxygen. In the cathode chamber, the electrochemical activation of Peroxymonosulfate (PMS) by ketones on intermediate products is expected to become an inherent catalytic technology for the selective oxidation of pollutants occurring in aquatic environments.

Bulletin of the National Research Centre 2023年第1期47卷 1-18页

作者： Shaarawi, Sayed I. Abutaleb, Khaled Aboelmagd, Ashraf R. Temraz, Tarek Marine Science –AdapTM Program Faculty of Science Suez Canal University Ismailia Egypt Egyptian Natural Gas Holding Company (EGAS) Petroleum and Mineral Resources Ministry Nasr City Cairo Egypt National Authority for Remote Sensing and Space Sciences (NARSS) Cairo Egypt Agricultural Research Council Natural Resources and Engineering (ARC-NRE) Pretoria South Africa School of Animal Plant and Environmental Sciences University of Witwatersrand Johannesburg South Africa

Transportation and Climate change are inextricably linked. As the transport sector is the primary consumer of petroleum products and therefore, contributes a significant share of greenhouse gases (GHGs). Mobile sources share ranges between 25 and 30% of total Egypt’s GHG emissions. So, Egypt is giving a great concern for natural gas vehicles (NGVs) as low-carbon alternative to gasoline/diesel vehicles. This study aims to analyze the economic and the environmental impact of the NGV fleet growth in Egypt with future prospective scenarios, concurrently with governmental strategy based on expansion of compressed natural gas fueling stations infrastructure and incentives for NGV transformation. Egypt’s NGV program led to about 5 Mt CO2 emissions reductions and about 21.57 billion EGP (US$1.4 billion) economic saving since starting up to end of 2021. And implementing of presidential initiative in 2021 to accelerate NGVs led to jumping in CO2 emissions reductions and economic saving by about 40% and 49% of pervious year, respectively. It is observed that scenario no. 1, of NGV adopting percent 15%, is the most fitted business as usual scenario to the presidential initiative and will lead to emissions reduction by about 30 Mt CO2 and economic saving by about 278 billion EGP (US$17.6 billion).

The nuclear power industry has historically used paper-based procedures, but a shift towards computer-based procedures (CBPs) has the potential to reduce human errors, alleviate mental workload, and improve work performance. Twenty-seven participants were randomly assigned to one of three CBP types using the Rancor Microworld Simulator, and each performed two different types of operational scenarios (startup and loss of feedwater). The three CBP types varied in levels of digitalization. It was hypothesized that there would be less favorable impressions of the most basic procedures, and that these would demonstrate lower usability than types with greater digitalization. Overall, our predictions were partially supported with some interesting caveats, specifically with some performance benefits for CBPs that provided indicators but not embedded controls. We discuss our findings in terms of optimal levels of digitalization/automation within nuclear operations and suggest pathways for future directions.

Hydrolysis of polyethylene terephthalate (PET) into terephthalic acid (TPA) is one key approach for waste PET recycling. However, achieving an in-depth understanding in PET hydrolysis remains challenging. Herein, we employed machine learning (ML) methods to interpret the PET conversion with a dataset compiled, containing 942 data points and rich hydrolysis factors of PET-related information, heating type, acid/base catalyst (ABC), organic solvent (OS), co-solvent, phase transfer catalyst (PTC), and operational condition. A Neural Network model was found to be the best for predicting PET conversion, with a testing R2 and RMSE of 0.93 and 8.45%. The model-based interpretation suggested that operational conditions accounted for 45% of importance, followed by ABC (19%), OS (12%), and PTC (12%). Furthermore, hydrolysis time, temperature, and ABC concentration were identified as the top-three factors positively influencing PET conversion. This work facilitates the catalyst and process optimization for PET hydrolysis to promote the plastic circular economy. © 2025, The Authors. All rights reserved.

The quest for viable and scalable biofuel sources has been at the forefront of scientific innovation for the past three decades. Due to its rich chemical constituents, microalgal biomass has emerged as a pivotal sustainable and scalable feedstock for biorefineries. This comprehensive review critically analyzes the different types of microalgae feedstock, concurrent extraction technologies, bio-pre-treatment procedures, and the key chemical and physical parameters influencing lipid formation and algal biofuel production. We propose a novel approach of photo-initiated culturing of algal biomass using photobioreactors (PBRs) to address the limitations of concurrent space and time-related constraints. The innovative photo bio-refinery strategy presented herein aims to enhance sustainability factors while minimizing emissions, catering to the needs of futuristic non-electric vehicles. A comparative quality analysis of microalgae-derived biofuel against conventional fossil fuels and other biofuels is conducted, considering chemical, environmental, economic, and social perspectives. Furthermore, we elucidate the efficacy of bio-pre-treatment strategies such as dehydration, hydrothermal liquefaction, pyrolysis, and gasification in optimizing biofuel production. The proposed photo biorefineries exhibit the potential to yield a diverse range of value-added products, including biodiesel, biogases, bio-fertilizers, bio-pesticides, bio-alcohols, dyes, proteins, carotenoids, and drug vitals. This review provides a comprehensive framework for the development of sustainable and efficient microalgae-based biorefineries, paving the way for a greener and more economically viable future in the biofuel industry. © 2024 Elsevier Ltd

The critical minerals industries in Indonesia may pose possible environmental and human health risks due to the release of pollutants into soil, water, and air, as well as the use of materials and energy. This study investigates the possible environmental and human health impacts of Indonesia's nickel, gold, copper, tin, and bauxite mining and processing industries. This study utilizes the latest version of the OpenLCA software, version 2.0, in combination with the Ecoinvent 3.8 database. To evaluate potential environmental consequences and health effects on humans, CML-IA Baseline and environmental Priority Strategies (EPS) are employed in product development. The EPS system was developed utilizing a hierarchical methodology with the objective of furnishing the product developer with data regarding the financial impact of human health impairment resulting from a particular product development. The production of one tonne of gold, nickel, bauxite, tin, and copper results in the emission of 7.34.E+07, 4.61.E+04, 3.10.E+04, 1.02.E+04, 8.01.E+03 kg CO₂ eq/t, respectively, contributing to global warming. This production is associated with asthma cases of 7.79.E+01 (gold industry), 2.21.E−03 (copper industry), 1.81.E−03 (tin industry), 9.21.E−04 (nickel industry), and 4.71.E−06 (bauxite industry) Personyears/t. Electricity consumption and the release of carbon dioxide are the main factors contributing to global warming. The primary cause of asthma cases is the utilization of fuel oil and electricity. Power plant chimneys can employ various technologies, such as cyclones, bag filters, and scrubbers, to mitigate the release of polluting gas emissions. The critical mineral industry must prioritize handling and governing of steam power facilities to minimize their negative effects on the environment and human health. © 2024 The Authors

Jagakarsa is an urban area in South Jakarta, Indonesia, that uses groundwater for raw water because there are no clean water supply facilities. The significant increase in the need for clean water due to increasing urbanization threatens groundwater availability to maintain the balance of the surrounding environment. Natural conditions with a deep layer of clay and a dense built environment further increase runoff capacity because water has difficulty seeping into the soil. The intense extraction of groundwater without balancing groundwater recharge results in land subsidence. Until now, there has been no research on this issue. Thus, our research is necessary. This research aims to assess the potential of groundwater infiltration areas in Jagakarsa. Due to limited data, as a first step, we used a qualitative model with MCDM analysis (AHP and MIF methods) integrated with GIS to map potential groundwater recharge areas. The AHP method is explained in detail with a matrix system formula, readers can understand the calculation steps more easily. This study uses five influencing factors: geological formation, land use, slope, rainfall, and soil type. The results show that most study locations have low potential (AHP 74.49 % and MIF 75.25 %) for groundwater recharge. This groundwater recharge potential map was validated using groundwater level measurements. The accuracy of the AHP is 74.51 %, and the MIF method reaches 75.26 %. Therefore, further research is needed to obtain appropriate and effective technology for maintaining groundwater availability. © 2024 The Authors
