The use of waste material in the form of disposable facemasks, based on polypropylene (PP) fibre in pavement structures is one of the essential initiatives for the future toward a sustainable environment. This study imparts a review of repurposing this waste and its use in asphalt pavements. The waste materials act as modifiers and can upgrade the performance of pavement and provide green technology with an eco-friendly environment. Utilization of waste material as an asphalt binder enhanced the engineering properties of asphalt pavements. In this research, different percentages of polypropylene as per weight of binder were used, such as 3%, 6%, 9%, 12% 15% and 3% were found to be optimum. Along with it, some important mechanical properties were assessed using hot mix asphalt (HMA). Marshall Stability was calculated at every concentration and contrasted with the control binder sample at 4% Optimum Asphalt Content (OAC). The rutting and cracking performance of the PP-modified binders was superior to that of the control binder, according to the results of the test on HMA mixed at OAC. The findings of the mix performance showed that the PP-modified binders improved the mixes' stiffness, durability, and stability. Overall, findings from the study suggest that waste PP has a good prospect of being utilized in asphalt binder modification.

    查看更多>>摘要：Traffic noise annoyance is considered to be the forerunner for other health problems. Identifying the factors having significant role in increasing the level of annoyance is important to reduce the health effects of traffic noise. Current study investigated the health impacts of traffic noise pollution and at the same time Multinomial Logistic (MNL)Regression model and Artificial Neural Network model were developed to identify the factors (demographic factors, noise exposure factors, environmental factors, road related factors and traffic related factors) responsible for traffic noise annoyance. LA(eq) was monitored on 31 sites along with common noise descriptors. LA(eq) values were 68.41 to 81.40 dBA during peak hours and 68.45 to 83.23 dBA during off peak hours, which are above the permissible limits of CPCB and WHO. A questionnaire survey was performed on 400 adult residents (294 males and 106 female), aged 20-70 y. Noise annoyance was measured on a self-rated scale (1-5). Multinomial Logistic Regression model identified significant correlation with regard to seven independent variables (with p < 0.05), including factors like gender (X1), age (X2), income (X3), exposure in years (X6), daily exposure (X7), LA(eq) (X8) and traffic volume(X9). Pseudo R-Square values suggest that the MNL regression model developed performed well in explaining the variation of the dependent variable, with Nagelkerke's R-Square value 0.95 indicating a strong fit. The ANN model confirmed, income as the most significant variable followed by age and exposure in years. The overall prediction accuracy of 94.3% for MNL regression and 85.7 % for ANN model was achieved. These results can be utilized by the health officials to plan effective measures to reduce the impact of traffic noise on exposed population especially in sensitive/silent zones like educational institutes, schools, hospitals and offices.

    2429-2441页
    查看更多>>摘要：Salinity stress has a negative impact on some morphological, physiological, and molecular processes during the germination of rosella seeds. Various strategies such as the application of humic acid are used to increase the tolerance of plants to salinity stress. Seed priming is also considered as a solution to the problem of poor germination, seedling establishment, and induction of pre- germination metabolic activities in crops under abiotic stress. The present study was conducted to evaluate the effect of seed treatment and humic acid on the different growth stages of roselle under salt stress conditions by performing two separate seedling trays and pot experiments. Seed treatment with 1% of Na2SO3 for 24 hours had the highest mean emergence percentage among studied priming treatments. The 200 mM level of salt stress reduced germination by 62% compared to normal conditions. Additionally, the highest emergence rate was obtained from 0.5%-Na2SO3 treatment at 12 hours under 50 mM of salt stress condition. Salinity reduced the values of the plant height, number of flowers, flower fresh weight, and flower dry weight. However, some priming and humic acid treatments, such as KCl treatment, decreased the negative impacts of salinity, enhancing flower dry weight by 138% compared to the control. In general, the highest values of flower-related traits under salinity were observed in KCl and Na2SO3 treatments. Furthermore, humic acid increased all the studied traits and improved salinity tolerance compared to not applying humic acid. It can be concluded that it is possible to reduce the adverse effect of salinity stress on Roselle plant cultivation through seed priming and application of humic acid.

    查看更多>>摘要：Disasters, whether natural or manmade, pose significant challenges at both the global and national levels, necessitating comprehensive strategies for mitigation, preparedness, response, and recovery. Globally, the impact of disasters is exacerbated by factors such as climate change, urbanization, and socioeconomic disparities, leading to heightened vulnerability and escalating humanitarian crises. In India, a country prone to various natural hazards, such as floods, cyclones, earthquakes, and droughts, disaster management is a critical concern due to its vast geographical expanse and dense population centres. In a post-landslide environment, victims must be brought to shelter locations in a safe manner. It is crucial to find a safer alternative path to accessing shelter sites because of the distortions that can occur due to disasters. In this article, we developed an algorithm to locate a circumvent route so that the distorted paths are skipped to obtain a better and safer route. By utilizing the closeness centrality circumvent algorithm, we demonstrated the improvement of the deformed routes to better circumvent routes regarding the number of decision edges, number of overlapped edges and total circumvent path distance with the real-time road networks of town of Kodaikanal, Tamilnadu.

    2455-2466页
    查看更多>>摘要：This paper proposes an evaluation method for sustainable development of low-carbon ecological construction in cities based on the Super-Efficiency Data Envelopment Analysis (SE-DEA) model. The method involves four steps: (1) constructing the SE-DEA model to determine the input and output indicators; (2) establishing an evaluation system using Analytic Hierarchy Process (AHP); (3) determining the weights of indicators using the entropy method; and (4) evaluating the sustainable development level of cities using the SE-DEA model and a comprehensive evaluation approach. The method was applied to 26 indicators in a case study. The results show that the proposed method achieves an accuracy above 90%, with the highest consistency reaching 96%, and an average evaluation time of 7.00s. The proposed method provides a more accurate, reliable, and efficient tool for evaluating the sustainable development of low-carbon cities.

    查看更多>>摘要：The sustainable operation of low-carbon transformation is the cognition of the government and enterprises. In view of the current situation that small and medium-sized enterprises are facing financial constraints, it is particularly important for the government to take incentives for them to achieve their low-carbon transformation. This paper builds a Stackelberg game model between a manufacturer subject to capital constraints and a retailer with low-carbon procurement needs, and introduces green credit subsidy, emission reduction research and development (R&D) technology subsidy and low-carbon product production subsidy into the model, and comprehensively analyzes three subsidy strategies effect and incentives for the manufacturer to reduce emissions. The research shows that although the low-carbon procurement demand of the retailer may not increase the additional emission rate of the capital-constrained manufacturer, it can increase the profits of the manufacturer and the retailer. Although the government's increase in green credit and emission reduction R&D technology subsidies can motivate the manufacturer to reduce emissions, it will cause a contradiction between emission reduction effects and corporate profits. The government's implementation of low- carbon product production subsidy can increase the profits of the manufacturer and the retailer, but the emission reduction effect may not be optimal. In addition to considering the factors of government subsidy intensity, it is also necessary to comprehensively consider the impact of basic market demand, the consumers' low-carbon preference, the bank interest rate and initial capital of the manufacturer on the emission reduction effect.

    查看更多>>摘要：The conventional manual method of neem fruit collection is laborious, uneconomical, and time-consuming. The cost of collecting neem fruits from the ground exceeds the selling price of neem fruits. There is no mechanical system available for collecting neem fruits from the ground. To address the above problems, a pneumatic suction collection system was explored, necessitating optimization of key variables influencing neem fruit collection and picking efficiency. The study investigated impeller diameter (I1: 152 mm, I2: 204 mm, I3: 250 mm), , impeller mount height (H1: 30 cm, H2: 45 cm, H3: 60 cm), suction hose diameter (D1: 80 mm, D2: 110 mm) and impeller speed (S1: 3500 rpm, S2: 4000 rpm, and S3: 4500 rpm). Experiments were conducted using various combinations of these variables on an experimental test rig. The maximum picking efficiency of 100 per cent and maximum collection efficiency of 99.67 per cent were observed for the combination of 250 mm impeller diameter (I3) with 80 mm suction hose diameter (D1), impeller speed 4500 rpm (S3) and 45 cm height of impeller (H2). The optimized combination levels of the variables were recommended for the development of prototype unit of ground collection system for neem fruit. This developed system promises to revolutionize neem fruit collection through mechanical means, offering a more efficient and economical alternative to manual methods.

    2493-2511页
    查看更多>>摘要：This research introduces an innovative approach combining the Backpropagation (BP) neural network, Decision-Making Trial and Evaluation Laboratory (DEMATEL) method, and NK model (BP-DEMATEL-NK) to identify critical factors, examine their intricate relationships, and simulate the optimal pathway for the green transformation and upgrading (GTU) of heavily polluting industries in the Beijing-Tianjin-Hebei region of China. Following an exhaustive literature review and a questionnaire survey, six key factors were identified: resource utilization, environmental pollution, innovation resources, innovation output, cost input, and performance output. The BP neural network determines the significance of these factors, and the DEMATEL method investigates their interrelationships. The NK model is subsequently employed to simulate the most effective GTU sequence: "cost input-* environmental pollution-* innovation resources-* innovation output-* resource utilization-* performance output". This study enriches the literature by proposing a comprehensive framework for understanding the synergistic evolution of environment, innovation, and benefit within the scope of industrial GTU. Furthermore, the findings offer valuable insights for policy-making and industrial transformation in China and other regions facing similar challenges.
