Abstract Recent years, the polarization response of ferroelectrics has been entirely studied. However, it is found that the polarization may disappear gradually with the continually applied of electric field. In this paper, taking K_0.48Na_0.52NbO₃(KNN) as an example, it was demonstrated that the residual polarization began to decrease when the electric field frequency increased to a certain extent using a phase-field methods. The results showed that the content of out-of-plane domains increased first and then decreased with the increase of applied electric field frequency, the maximum polarization disappeared at high frequencies, and the hysteresis loop became elliptical.

Abstract The blending of hydrogen into natural gas provides an optimal solution for large-scale hydrogen transport, utilizing existing natural gas pipelines for mixed conveyance. The thermophysical parameters of hydrogen-enriched natural gas (HENG) significantly influence the design and operation of gas transmission networks. Therefore, accurate prediction of the thermophysical parameters of HENG is crucial. However, due to the effects of hydrogen blending, the adaptability of commonly used equations of state (EoSs) to HENG remains uncertain, especially at high hydrogen blending ratios (HBRs). In this study, the accuracy of the EoSs of PR, BWRS, AGA8-92DC, and GERG-2008 is… More >

Abstract Sorghum is the fifth most required cereal crop globally. Sorghum bicolor has the advantage of being adaptive to both lowland and dryland, with drought-tolerant and wide adaptability. The low nutrient availability in dryland requires additional effective fertilizers to increase sorghum productivity. The research aimed to assess the application of organic, inorganic, and biofertilizers for sorghum productivity on dryland. Research in Central Java, Indonesia as dryland sorghum areas, from November 2022 to February 2023. The experiment cooperates with the farmers in a split-plot design, the main plot was two varieties and subplots of four fertilizers. The enhanced… More >

Abstract The integration of solar and wind energy into the electrical grid has received global research attention due to their unpredictable characteristics. Because wind energy varies across all timescales of utility activity, renewable energy generation should be supplemented and enhanced, from real-time, minute-to-minute variations to annual alterations influencing long-term strategy. Wind energy generation does not only fluctuate but is also challenging to accurately forecast the timeframes of significance to electricity decision makers; day-ahead and long-term making plans of framework sufficiency such as meeting the network peak load annually. A utility that integrates wind and solar energy… More >

Abstract Existing pressure drilling technologies are based on different principles and display distinct characteristics in terms of control pressure and degree of formation adaptability. In the present study, the constant-bottom-hole-pressure (CBHP) and controlled-mud-level (CML) dual gradient drilling methods are considered. Models for the equivalent circulating density (ECD) are introduced for both drilling methods, taking into account the control pressure parameters (wellhead back pressure, displacement, mud level, etc.) and the relationship between the equivalent circulating density curve in the wellbore and two different types of pressure profiles in deep-water areas. The findings suggest that the main pressure… More >

Abstract As a macronutrient, Phosphorus (P) takes many roles in plant growth and development. It should be significant to explore the molecular mechanism of low-phosphorus stress response of plants. Phosphate starvation response (PHR) transcription factors play important roles in response to phosphorus deficiency stress in plants. In this study, we isolated a gene related to the plant phosphorus signaling system from the acid-soil-resistant centipedegrass (Eremochloa ophiuroides [Munro] Hack.), termed EoPHR2. The subcellular localization of EoPHR2 protein was observed to be nuclear located. The expression patterns of EoPHR2 in different tissues and Al/Pi-stress conditions were analyzed by qRT-PCR, they More >

Abstract Prophages are temperate phages integrated into the host bacterial genome. They play an important role in the adaptation and the pathogenicity of bacteria, especially pathogenic bacteria. In this review, we described the distribution of prophages in different hosts and different environments, and focused on the significance of prophages. At the singlecell level, prophages can help the host adapt to harsh external environments by directly carrying virulence genes, encoding regulatory factors and activating lysogeny. At the population level, prophages can influence the overall evolutionary direction and ecological function of the host bacterial community. This review will More >

Abstract We conducted a comparative study from 2008 to 2011 to study the adaptability and stability of grain yield of upland rice in two regions of Campeche, Mexico. The individual and combined statistical analysis, showed highly significant differences in grain yield of different genotypes in both regions. The experimental error variance was uniform, both effects of repetition/location and variety/location were highly significant. The results of analysis for grain yield stability parameters showed highly significant effects for 12 treatments, and significant for one. Eighteen genotypes showed a significant variation in the effects of deviation from the regression More >

Abstract Our objective was to determine the genotype-environment interaction (GxE) in a hybrid integrated by maize lines either carrying or not balanced lethal systems. Experiments were conducted in three locations over a period of two years considering each yearlocation combination as a different environment. Yield data were analysed using the Additive Main Effects and Multiplicative Interaction (AMMI) model and the Sites Regression Analysis (SREG). Results were represented by biplots. The AMMI analysis was the best model for determining the interaction. More >
