Various initiatives promote the recycling and reuse of these waste materials for sustainable practices. This paper presents a comparative study on the influence of incorporating partial contents of recycled fine rubber crumbs in the recycled construction and demolition waste (RCDW), crushed aggregates, and river sand on the shear parameters (c, ϕ) of the mix. The fine rubber crumbs were mixed with the aforementioned materials in varying contents, i.e., 0%, 2%, 4%, and 6% by weight. The minimum and maximum densities were evaluated, and the strain-controlled direct shear tests were performed using the above combinations at 60% relative density to evaluate the shear parameters. The results showed a significant improvement in the ϕ-values of all three materials when mixed with rubber crumbs. The improvement ratio was higher for RCDW than for the other materials. However, a slight decrease in the cohesion values was observed. The outcomes of this study demonstrate the potential of waste rubber crumbs to enhance the shear strength of waste and natural construction materials, contributing to the development of innovative infrastructure solutions and reducing environmental impact.</p></div>","PeriodicalId":717,"journal":{"name":"National Academy Science Letters","volume":"48 4","pages":"475 - 478"},"PeriodicalIF":1.3,"publicationDate":"2024-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145170596","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In traditional agriculture, farmers’ identification of pests and diseases primarily relies on experience, which has defects such as low efficiency and high misjudgment rate. Hiring experienced experts will significantly increase the cost of investment. Given the above problems, this study proposes an improved residual network for jute pest identification. Based on the ResNet18 model, a hybrid attention module is embedded to construct a new convolutional neural network, JuteNet. The experimental results show that the recognition accuracy of the JuteNet network is 93.24%, which is 3.47% higher than that of the ResNet18 network. By introducing an appropriate amount of attention module, the recognition accuracy of the network can be improved without significantly increasing the training cost of the model. In addition, the network’s superiority is further demonstrated by ablation experiments and comparison with other models. This experiment verifies the feasibility of a deep-learning algorithm for plant pest identification.

Assimilate and nutrient remobilization were determined based on assimilate (dry biomass) of different plant parts (leaf, stem, root, filled-grain, chaff) and their corresponding nutrient content (nitrogen and phosphorus) at anthesis and maturity. Results showed that varying water regimes had an equivalent effect on post-anthesis assimilate nitrogen and phosphorus remobilization. However, both assimilate and nutrient remobilization efficiencies, as well as their contributions to grain, were significantly enhanced under deficit-water conditions, with a stronger effect observed under prolonged water-deficit (6-DADPW). The efficiency of nutrient/assimilate remobilization found in the order: phosphorus (46–50%) > nitrogen (24–29%) > dry matter (15–19%). Both moderate (3-DADPW) and prolonged (6-DADPW) deficit-water conditions reduced yield by 10% and 35% compared to 1-DADPW. Hence, the elevated scale of assimilates and nutrient remobilizations under water-deficit conditions suggests post-anthesis remobilization traits deserve special consideration in selecting/breeding stress-tolerant cultivar(s).</p></div>","PeriodicalId":717,"journal":{"name":"National Academy Science Letters","volume":"48 3","pages":"363 - 366"},"PeriodicalIF":1.3,"publicationDate":"2024-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145171701","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
