    Hussein El Hage Hassan1,*, Laurence Charbel2, Ninon Blond3

    Revue Internationale de Géomatique, Vol.32, pp. 53-78, 2023, DOI:10.32604/RIG.2023.043180

    Abstract The western edge of the Jord Tannourine-Aaqoura plateau (Lebanon) is a Mediterranean mountain region that unites the suitable conditions for water erosion: abundant rain, steep slopes, ravaged natural vegetation cover, and soil susceptible to degradation. However, the agricultural terraces developed for decades remain a robust practice to limit runoff and expand the useful agricultural area. To determine water erosion and the role of anti-erosion practices, the adopted methodology is based on the universal USLE equation revised (RUSLE). The combination of model parameters in a GIS has made it possible to define that water erosion can exceed 51 t/ha/year, mainly in… More >

    Kai Zhu1, Hao Chen1,*, Shuang Wang1,*, Chuan Yuan1,2, Bin Cao3, Jun Ni1, Lujiang Xu4, Anqing Zheng5, Arman Amani Babadi1

    Journal of Renewable Materials, Vol.11, No.6, pp. 2849-2864, 2023, DOI:10.32604/jrm.2023.026317

    Abstract Microalgae biomass is an ideal precursor to prepare renewable carbon materials, which has broad application. The bioaccumulation efficiency (lipids, proteins, carbohydrates) and biomass productivity of microalgae are influenced by spectroscopy during the culture process. In this study, a bilayer plate-type photobioreactor was designed to cultivate Chlorella protothecoides with spectral selectivity by nanofluids. Compared to culture without spectral selectivity, the spectral selectivity of Ag/CoSO4 nanofluids increased microalgae biomass by 5.76%, and the spectral selectivity of CoSO4 solution increased by 17.14%. In addition, the spectral selectivity of Ag/CoSO4 nanofluids was more conducive to the accumulation of nutrients (29.46% lipids, 50.66% proteins, and… More > Graphic Abstract

    Gyung Deok Han1, Dae Ho Jung2, Seong Heo3,*, Yong Suk Chung1,*

    Phyton-International Journal of Experimental Botany, Vol.91, No.11, pp. 2583-2590, 2022, DOI:10.32604/phyton.2022.022866

    Abstract In the smart farm, we can control every detail for production. Collecting every factor that affects the crop’s final yield is necessary to optimize its efficiency. The SPAD values were observed in the ‘Star’ cultivar blueberry (Vaccinium darrowii) three times a day and at three different plant heights. The pattern of SPAD value change was different by the planting position. Ground planted blueberry (V. darrowii) represented a stable SPAD value during the day and at the different heights. However, the SPAD value was increased by time in pot-planted blueberry (V. darrowii). Also, the SPAD value of pot-planted blueberry was lower… More >

    Abstract In agricultural production, a single insect-resistant and disease-resistant variety can no longer meet the demand. In this study, the expression vector pCAMBIA-3301-PR1 containing the disease-resistant gene PR1 was constructed by means of genetic engineering, and the PR1 gene was genetically transformed to contain the PR1 gene through the pollen tube method. In CryAb-8Like transgenic high-generation T7 receptor soybean, a new material that is resistant to insects and diseases is obtained. For T2 transformed plants, routine PCR detection, Southern Blot hybridization, fluorescence quantitative PCR detection, indoor and outdoor pest resistance identification and indoor disease resistance identification were performed. The results showed… More >

    Differential Evolution Algorithm Based Self-adaptive Control Strategy for Fed-batch Cultivation of Yeast

    Aiyun Hu1, Sunli Cong1,*, Jian Ding2, Yao Cheng1, Enock Mpofu3

    Computer Systems Science and Engineering, Vol.38, No.1, pp. 65-77, 2021, DOI:10.32604/csse.2021.016404

    Abstract In the fed-batch cultivation of Saccharomyces cerevisiae, excessive glucose addition leads to increased ethanol accumulation, which will reduce the efficiency of glucose utilization and inhibit product synthesis. Insufficient glucose addition limits cell growth. To properly regulate glucose feed, a different evolution algorithm based on self-adaptive control strategy was proposed, consisting of three modules (PID, system identification and parameter optimization). Performance of the proposed and conventional PID controllers was validated and compared in simulated and experimental cultivations. In the simulation, cultivation with the self-adaptive control strategy had a more stable glucose feed rate and concentration, more stable ethanol concentration around the… More >

    Abstract Despite the great potential of photosynthetic microbes in the production of renewable fuels, value-adding chemicals, and water treatment, etc., commercial utilization of them is significantly hindered by the lack of techniques to accurately monitor the thermodynamic and kinetic characteristics of the In-situ growth of microbes under controlled light illumination for optimal cultivation. Herein, we demonstrated that a newly developed highly sensitive photo-microcalorimetric system successfully captured the impacts of the light wavelength and strength on the thermodynamic and kinetic parameters of the In-situ growth of Rhodopseudomonas palustris, a representative photosynthetic microorganism. To our best knowledge, this is the first time that… More >

    Abstract Biochar amendment is generally recognized as an effective mitigation option of methane (CH4) emissions from rice cultivation. Although its mitigation mechanisms are not well understood, the potential relevance of surface area and porosity of biochar has been discussed. This study aimed to evaluate the application of different biochar particle sizes on CH4 production, oxidation, and emissions from rice cultivation in a clay loam soil, based on the assumption that porosity and surface area of biochar are directly related to its mitigation effects. Rice was grown under greenhouse conditions for two growing seasons, either with 0.5–2 mm (small, SB) or with… More >
