    EFFECT OF TEMPERATURE ON WATER TRANSPORTATION IN NANOCHANNEL

    Yongbin Zhang*

    Frontiers in Heat and Mass Transfer, Vol.9, pp. 1-4, 2017, DOI:10.5098/hmt.9.16

    Abstract The flow factor approach model was used to study the effect of temperature on water transportation in a nano slit pore flow driven by the pressure. The influences of the temperature on the density and viscosity of water and on the water-wall interaction were considered. The results show that enhancing the temperature of water significantly improves water transportation in nanochannel, especially when the channel height is so low that the water non-continuum effect is significant. The mechanism of this temperature effect is that the temperature increase not only appreciably reduces the water viscosity but also More >

    Overexpression of the LcPIN2 and LtPIN2 Gene in Arabidopsis thaliana Promotes Root Elongation

    Zijian Cao#, Guoxia Xue#, Lingfeng Hu, Haoxian Qu, Shuang Liang, Jisen Shi, Jinhui Chen*, Zhaodong Hao*

    Phyton-International Journal of Experimental Botany, Vol.92, No.8, pp. 2383-2397, 2023, DOI:10.32604/phyton.2023.029845

    Abstract The auxin polar transporter, PIN-FORMED 2 (PIN2) plays an important role in root development. However, it remains unclear whether PIN2 genes form two Liriodendron species, L. chinense (LcPIN2) and L. tulipifera (LtPIN2), are both involved in root development and whether and to what extent these two genes diverge in function. Here, we cloned and overexpressed LcPIN2 and LtPIN2 in Arabidopsis thaliana wild-type (WT) and Atpin2 mutant. Phylogenetic and sequence analysis showed a small degree of differentiation between these two Liriodendron PIN2 genes. Tissue-specific gene expression analysis indicated that both Liriodendron PIN2 genes were highly expressed in roots, implying a potential role in root… More >

    Biological Analysis and Response to Low Phosphate Stress of Phosphate Transporter Family 1 (PHT1)) Genes in Solanum tuberosum L.

    Yangyang Du1, Yuanyuan Bao2, Lu Zheng1, Qinglong Tian1, Xinyong Zhang1,*

    Phyton-International Journal of Experimental Botany, Vol.92, No.8, pp. 2325-2348, 2023, DOI:10.32604/phyton.2023.027642

    Abstract Inorganic phosphate (Pi) is one of the main nutrients necessary for plant growth. Phosphate transporters mediate the acquisition, transport and recycling of phosphate, which is essential for plant growth and development. Although PHT1 has been reported in many plants at home and abroad, it is rarely studied in potato. Therefore, it is of great significance to study the PHT1 family members in order to understand the molecular response mechanism of potato in low phosphate state. In this study, a total of 6 potato PHT1 genes were identified and isolated. It was found that after the expression of… More >

    Effect of Freeze-Thaw Cycles on Chloride Transportation in Concrete: Prediction Model and Experiment

    Yongdong Yan*, Youdong Si, Chunhua Lu, Keke Wu

    Structural Durability & Health Monitoring, Vol.17, No.3, pp. 225-238, 2023, DOI:10.32604/sdhm.2022.022629

    Abstract This research aims to investigate the effect of frost damage on chloride transportation mechanism in ordinary and fiber concrete with both theoretical and experimental methods. The proposed theoretical model takes into account the varying damage levels caused by concrete cover depth and freeze-thaw cycles, which are the two primary parameters affecting the expression of the chloride diffusion coefficient. In the experiment, three types of concrete were prepared: ordinary Portland concrete (OPC), polypropylene fiber concrete (PFC), and steel fiber concrete (SFC). These were then immersed in NaCl solution for 120 days after undergoing 10, 25, and… More >

    Research on Parking Path Planing Based on A-Star Algorithm

    Zhiliang Deng, Dong Wang*

    Journal of New Media, Vol.5, No.1, pp. 55-64, 2023, DOI:10.32604/jnm.2023.040252

    Abstract The issue of finding available parking spaces and mitigating congestion during parking is a persistent challenge for numerous car owners in urban areas. In this paper, we propose a novel method based on the A-star algorithm to calculate the optimal parking path to address this issue. We integrate a road impedance function into the conventional A-star algorithm to compute path duration and adopt a fusion function composed of path length and duration as the weight matrix for the A-star algorithm to achieve optimal path planning. Furthermore, we conduct simulations using parking lot modeling to validate More >

    Non-Cooperative Game of Coordinated Scheduling of Parallel Machine Production and Transportation in Shared Manufacturing

    Peng Liu1,*, Ke Xu1,2, Hua Gong1,2

    CMC-Computers, Materials & Continua, Vol.76, No.1, pp. 239-258, 2023, DOI:10.32604/cmc.2023.038232

    Abstract Given the challenges of manufacturing resource sharing and competition in the modern manufacturing industry, the coordinated scheduling problem of parallel machine production and transportation is investigated. The problem takes into account the coordination of production and transportation before production as well as the disparities in machine spatial position and performance. A non-cooperative game model is established, considering the competition and self-interest behavior of jobs from different customers for machine resources. The job from different customers is mapped to the players in the game model, the corresponding optional processing machine and location are mapped to the… More >

    EFFECTS OF PHYSICOCHEMICAL PARAMETERS ON THE OPTIMIZED TOPOLOGY OF CATALYST IN MICRO REACTORS

    Xun Liu, Li Chen* , Wen-Quan Tao

    Frontiers in Heat and Mass Transfer, Vol.14, pp. 1-9, 2020, DOI:10.5098/hmt.14.16

    Abstract Fluid flow, mass transport and catalytic reaction in micro-reactors with catalyst are studied. Optimized structures of the catalyst generating the maximum reaction rate are explored by numerically solving the reactive transport processes combined with topology optimization schemes in COMSOL 5.3a. Effects of several physicochemical parameters including pressure drop, reaction rate constant, permeability of the porous catalyst and radius of the reactor are investigated. Distributions of the optimized structures, velocity, pressure and concentration are discussed in detail. Results show that the four physicochemical parameters have significant effects on the optimized structures of the catalyst obtained, indicating More >

    Effects of Different Nitrogen and Phosphorus Synergistic Fertilizer on Enzymes and Genes Related to Nitrogen Metabolism in Wheat

    Yajun Li, Yihui Wang, Shuang Chen, Yu Gao, Yan Shi*

    Phyton-International Journal of Experimental Botany, Vol.92, No.7, pp. 2151-2164, 2023, DOI:10.32604/phyton.2023.027930

    Abstract

    In recent years, in order to improve nutrient use efficiency, especially nitrogen use efficiency, fertilizer value-added technology has been developed rapidly. However, the mechanism of the effect of synergistic fertilizer on plant nitrogen utilization is not clear. A study was, therefore, conducted to explore the activities and gene expression of key enzymes for nitrogen assimilation and the gene expression of nitrogen transporters in wheat after the application of synergistic fertilizer. Soil column experiment was set up in Qingdao Agricultural University experimental base from October 2018 to June 2019. Maleic acid and itaconic acid were copolymerized with
