Abstract Background Photosynthetic pigments participating in the absorption, transformation and transfer of light energy play a very important role plant growth. While, spatial distribution foliar is an indicator environmental stress, such as pests, diseases heavy metal stress. Results In this paper, situ quantitative visualization chlorophyll carotenoid was realized by combining Raman spectroscopy with calibration model transfer, laboratory spectral successfully extended to portable field...

Leaf gas exchange, chlorophyll fluorescence and activities of antioxidant enzymes were studied in two pepper (Capsicum annuum L.) cultivars grown under drought (D) heat (H), as well combination (HD). The drought-tolerant cv. Zhengjiao 13 exhibited greater net photosynthetic rate (PN) cytochrome respiratory pathway activity (RSHAM), lower contents superoxide radical hydrogen peroxide, compared to the drought-sensitive Longkouzaojiao. PN RSHAM decreased ROS production increased D HD both...

Wood formation is a complicated process under the control of large set transcription factors. NAC factors are considered “master switches” in this process. However, few members have been cloned and characterized Eucalyptus , which one most economically important woody plants. Here, we reported an factor from grandis EgNAC141, has no Arabidopsis orthologs associated with xylogenesis-related processes. EgNAC141 was predominantly expressed lignin-rich tissues, such as stem xylem. Overexpression...

Out-of-phase synchronization (OPS) fault may occur to the turbine generator used in gas-steam combined cycle units, which seriously endanger operation stability of unit. To investigate influences rotor structure on field current and electromagnetic a under OPS, 2-D field-circuit-grid coupled model (FCGCM) 150-MW is established. By using established FCGCM, slot indexing number (RSIN) magnetic permeability wedge OPS 180° were studied. A no uniform coefficient (MNC) was proposed evaluate...

Organisms are frequently exposed to mixtures of heavy metals because their persistence in the environment. The mixture toxicity should therefore be evaluated perform a rational environmental risk assessment for organisms. In this study, we determined inhibition five (Cu2+, Co2+, Zn2+, Fe3+ and Cr3+) binary Photobacterium phosphoreum (P. phosphoreum). We obtained following results: (1) order individual was Zn2+>Cu2+>Co2+>Cr3+>Fe3+, (2) different combined effects (additive, synergistic...

The aim of this study was to explore how the mitochondrial alternative oxidase (AOX) pathway alleviates photoinhibition in chilled tomato (Solanum lycopersicum) seedlings. Chilling induced seedlings despite increases thermal energy dissipation and cyclic electron flow around PSI (CEF-PSI). inhibited function PSII blocked transport at acceptor side, however, it did not affect oxygen-evolving complex on donor side PSII. Upregulation AOX protects against by improving photosynthetic under...

Abstract Since 2006 the University of Houston has evaluated CO2 sequestration potential in a deep saline aquifer system Ness County, Kansas. This paper is summary on simulation part project. Combining 3D seismic and dense well control, static model was constructed history matching accomplished.Good validates geological same can then be further used for prediction. After matching, several models were to study injection rate storage safety issues. A full formation including sallow layers...

The load forecasting research for an NPS faces challenges including a high model accuracy, non-sharing of data, and communication cost. This paper proposes method NPS, based on efficient federated transfer learning (FTL). adversarial feature extractor is added the basis that FTL can effectively parameter features non-mask to local make up loss mask prediction accuracy. In order improve efficiency gradient compression (FL), depth dynamic threshold sensing proposed, which replaces sparse...

Due to the solid rotor structure, High-Voltage Line-Start Solid Rotor Permanent Magnet Synchronous Motor (HVLSSR-PMSM) operates with high temperature rise. If ventilation path cannot take heat away in time, will overheat or even may led thermal demagnetization for permanent magnet. Therefore, it is of great significance study issues HVLSSR-PMSM. In paper, fluid field and a 315 kW, 6 kV HVLSSR-PMSM air-cooled hybrid systems are investigated. Firstly, electromagnetic analysis machine done by...

Abstract It is important to determine the characteristics associated with success of alien species. However, there no universal syndrome invasion reproductive explain invasiveness has not been identified. Comparative studies on congeneric successful or non‐successful species are beneficial for revealing drivers and predicting future distributions. Reproductive biological characteristics, including mating system, phenology flowering, floral syndrome, pollination biology seed germination have...

To research the influence of rotor structure on field current and electromagnetic a turbine generator under Out-of-Phase Synchronization(OPS), an 2-D Field-Circuit-Grid Coupled Model (FCGCCM) 150MW is established. By using established FCGCCM, oscillation ratio (FCOR) OPS 180° was studied, when slot indexing number changed magnetic wedge used common slots. A nonuniform coefficient (MNC) proposed to evaluate nonuniformity rotor. The relations MNC were investigated.

Abstract Nitrogen (N) has been considered a crucial factor influencing plant invasions. Many studies have assessed responses of alien plants to different N availabilities. However, in natural soils, comes inorganic and organic forms. Few explored yet whether species forms are related their naturalization success globally. We selected 22 common herbaceous native Germany that all become naturalized elsewhere the world, but vary extent. grew under six conditions differed availability or form N,...

Time-lapse seismic modeling is routinely used to detect the state of hydrocarbon reservoirs at periodic time intervals. The Dickman field located in U. S. midcontinent provides two possible [Formula: see text] sequestration targets: a regional deep saline reservoir primary objective, and shallower, mature, depleted oil secondary objective. goal this work characterize simulate monitoring movement before, during, after its injection into these targets, including fluid flow paths, property...

With the explosive development of power edge equipment and continuous improvement in inspection performance, requirements substations terminal equipment, such as drones with limited resources, cannot meet strict delay energy consumption requirements. This paper proposes an adaptive partitioning strategy for heterogeneous substation systems. First, a layer prediction model are established on each node, nonlinear characteristics related to trained. On this basis, deep neural network (DNN)...

<title>Abstract</title> In certain regions, the limited coverage capability of ground base stations (BSs), as well their susceptibility to interference or natural disasters, has resulting in weakened hardware capabilities. As a result, they cannot meet computational task processing requirements terrestrial mobile users (MUs). order low-delay and low-energy consumption tasks for MUs, while ensuring high throughput, we first introduce Space-Terrestrial Collaborative offloading architecture...
