NAC proteins in plants respond to stress and play an important role in plant growth regulation. This regulation occurs through a variety of downstream eff ects mediated by plant hormones in response to stress. In this study, we performed a systematic genome-wide analysis of the NAC gene family in tomato based on genome version SL4.0. We identifi ed 99 SlNAC genes by abiotic stress analysis of conserved motifs and gene structure, phylogenetic analysis, cis-element analysis, chromosome localization analysis, synteny relationship and expression pattern analysis. These 99 SlNAC genes were distributed on all 12 chromosomes. Except for genes without introns, there was no signifi cant correlation between gene structures and phylogenetic relationships. Most of the cis-elements identifi ed were associated with plant hormones and environmental responses. There were 77 SlNAC genes that showed no homogeneity between tomato and wild rice, suggesting that these homologous genes arose after the diff erentiation of dicotyledonous and monocotyledonous plants. The comprehensive analysis of the SlNAC gene family provides a valuable resource for studying this gene family in tomato and a foundation for further study of the functional characteristics of these genes.

This paper uses the switching function approach to present a simple state model of the Vienna-type rectifier. The approach introduces the relationship between the DC-link neutral point voltage and the AC side phase currents. A novel direct power control (DPC) strategy, which is based on the sliding mode control (SMC) for Vienna I rectifiers, is developed using the proposed power model in the stationary α-β reference frames. The SMC-based DPC methodology directly regulates instantaneous active and reactive powers without transforming to a synchronous rotating coordinate reference frame or a tracking phase angle of grid voltage. Moreover, the required rectifier control voltages are directly calculated by utilizing the non-linear SMC scheme. Theoretically, active and reactive power flows are controlled without ripple or cross coupling. Furthermore, the fixed-switching frequency is obtained by employing the simplified space vector modulation (SVM). SVM solves the complicated designing problem of the AC harmonic filter. The simplified SVM is based on the simplification of the space vector diagram of a three-level converter into that of a two-level converter. The dwelling time calculation and switching sequence selection are easily implemented like those in the conventional two-level rectifier. Replacing the current control loops with power control loops simplifies the system design and enhances the transient performance. The simulation models in MATLAB/Simulink and the digital signal processor-controlled 1.5 kW Vienna-type rectifier are used to verify the fast responses and robustness of the proposed control scheme.

The approach introduces the relationship between the DC-link neutral point voltage and the AC side phase currents. A novel direct power control (DPC) strategy, which is based on the sliding mode control (SMC) for Vienna I rectifiers, is developed using the proposed power model in the stationary ${\alpha}-{\beta}$ reference frames.

In this study, two Fusarium strains namely ZSY and MJY were successfully isolated from the contaminatedsoil of Dabaoshan smelter in Shaoguan City, and utilised as a biosorbent for the removal of Pb(II) ions fromaqueous solution. Effect of pH (6), agitation speed (150 rpm), biomass concentration (1 g/L), initial Pb(II)concentration, contact time (60 min), and effect of temperature (323 K) was investigated. Kinetic andisotherm results showed that the removal of Pb(II) ions onto ZSY and MJY werefitted well with thepseudo-second-order and Langmuir isotherm models (232.56 and 263.16 mg/g). In addition thermodynamicstudies were also discussed.
