Maintaining stability of ecosystem functions in the face global change calls for a better understanding regulatory factors functionally specialized microbial groups and their population response to disturbance. In this study, we explored issue by collecting soils from 54 managed ecosystems China conducting microcosm experiment link disturbance, elemental stoichiometry, genetic resistance. Soil carbon:nitrogen:phosphorus (C:N:P) stoichiometry imparted greater effect on abundance associated...
Permanent-magnet (PM) synchronous machines (PMSMs) can provide excellent performance in terms of torque density, energy efficiency, and controllability. However, PMs on the rotor are prone to centrifugal force, which may break their physical integrity, particularly at high-speed operation. Typically, bound with carbon fiber or retained by alloy sleeves surface. This paper is concerned design a retaining sleeve for 1.12-MW 18-kr/min PM machine; its electromagnetic investigated 2-D...
In grasslands, forage and livestock production results in soil nutrients deficit as grasslands typically receive no nutrient inputs, leading to a loss of grassland biomass. The application mature compost has been shown effectively increase availability. However, research on fertilization regime influence potential microbial ecological regulation mechanisms are rarely conducted soil. We two-year experiment meadow steppe focusing above- belowground consequences organic or Trichoderma...
Abstract Microbial generalists and specialists coexist in the soil environment while having distinctive impacts on microbial community dynamics. In ecology, underlying mechanisms as to why a species is generalist or specialist remain ambiguous. Herein, we collected soils across national scale identified bacterial according niche breadth at level (OTU level), single‐nucleotide differences each were measured investigate intraspecific variation (at zero‐radius OTU level). Compared with that of...
The cage and reluctance rotors are two major types of rotor structures used in the doubly fed brushless machine (DFBM). In order to study comparatively effects different structure on DFBM, a prototype has been specially designed built. experimental parameter performance comparisons between axially laminated anisotropic (ALA) cage-rotor machines presented. It is found that DFBM better starting asynchronous characteristics; however, ALA reluctance-rotor exhibits synchronous operation...
Electromagnetic design of a 1.12-MW, 18 000-r/min high-speed permanent-magnet motor (HSPMM) is carried out based on the analysis pole number, stator slot rotor outer diameter, air-gap length, permanent magnet material, thickness, and arc. The no-load full-load performance HSPMM investigated in this paper by using 2-D finite element method (FEM). In addition, power losses including core loss, winding eddy current air friction loss are predicted. Based analysis, prototype manufactured...
The brushless doubly fed generator (BDFG) shows the great potential for use in large variable speed wind turbines due to its high reliability and cost benefits of a partially rated power electronics converter. However, it suffers from compromised efficiency factor comparison with conventional induction or synchronous generators. Therefore, optimizing BDFG, especially rotor, is necessary enhancing torque density market competitiveness. In this paper, novel cage-assisted magnetic barrier...
Soybean (Glycine max L.) is a major legume crop that mainly distributed in temperate regions. The adaptability of soybean to grow at relatively high latitudes attributed natural variations genes and quantitative trait loci (QTLs) control flowering time maturity. Identification new QTLs map-based cloning candidate are the fundamental approaches elucidating mechanism underlying adaptation. To identify novel QTLs/genes, we developed two F8:10 recombinant inbred lines (RILs) evaluated traits...
Trichoderma species have been used widely as biocontrol agents for the suppression of soil-borne pathogens. However, some antagonistic mechanisms are not well characterized. In this study, a series laboratory experiments were designed to characterize importance mycoparasitism, exoenzymes, and volatile organic compounds (VOCs) by harzianum T-E5 control Fusarium oxysporum f. sp. cucumerinum (FOC). We further tested whether these inducible upregulated in presence FOC. The results follows:...
Trichoderma spp. are proposed as major plant growth-promoting fungi (PGPF) to increase plants growth and productivity. Mowing can stimulate aboveground regrowth improve biomass nutritional quality. However, the synergistic effects of mowing on growth, particularly underlying microbial mechanisms mediated by rhizosphere soil chemical compounds, have rarely been reported. In present study, we employed harzianum T-63 conducted a pot experiment investigate effect Trichoderma-inoculation alfalfa...
In order to improve the ability of magnetic levitation feed platform controllable excitation linear synchronous motor (CELSM) resist external disturbance, a sliding mode control method based on fuzzy switching gain adjustment is proposed. According operation mechanism CELSM, voltage equation, flux force and state equation CELSM are established. The surface designed, integral term introduced eliminate steady-state error system. reaching law designed reduce chattering by using saturation...
Electrolytic capacitors are extensively used in power converters but they bulky, unreliable, and have short lifetimes. This paper proposes a new capacitor-free high step-up dc-dc converter design for renewable energy applications such as photovoltaics (PVs) fuel cells. The primary side of the includes three interleaved inductors, main switches, an active clamp circuit. As result, input current ripple is greatly reduced, eliminating necessity capacitor. In addition, zero voltage switching...
