A novel and efficient method for the synthesis of difluoroalkylated benzofuran, benzothiophene, indole derivatives via palladium-catalyzed aryldifluoroalkylation 1,6-enynes with ethyl difluoroiodoacetate arylboronic acids has been established. High reaction efficiency, mild conditions, broad substrate scope, good functional group tolerance are features this protocol. Notablely, resultant products can be smoothly converted into CF2-containing benzofurans, benzothiophenes indoles through an...
Background Pesticides are widely used in agricultural production to control insect pests and regulate plant growth China, which may result the presence of some pesticide residues vegetables. However, few studies monitoring pesticides have been conducted Henan Province. The aim this study was evaluate level commonly consumed vegetables regions Methods In study, we collected 5,576 samples 15 different 17 areas from Province during 2020. Eight kinds were analyzed by gas chromatography-mass...
Increasing evidence suggested that the expression and inter-regulation of long noncoding RNA (lncRNA), microRNA (miRNA), messenger (mRNA) were related to development diabetes. Based on bioinformatics analysis, this study aimed comprehensively analyze dysregulated molecules new-onset type 2 diabetes mellitus (T2DM). Twenty-four patients with T2DM included as cases, sex- age-matched participants controls. The differentially expressed lncRNAs, miRNAs, mRNAs between two groups screened by...
This article proposes a fast and effective optimization procedure to achieve low material cost of the ferrite permanent magnet assisted synchronous reluctance machine (PMaSynRM). The key is high pole utilization first then limit design margin output torque efficiency reduce significantly. Moreover, rotor overhang structure reduces costs improves space utilization. Four steps with different functions are arranged, combining nondominated sorting genetic algorithm (NSGA-II) nonlinear...
This paper proposes a simplified lumped parameter thermal network (LPTN) model for analysis under the inter-turn short-circuit (SC) faults of five-phase fault-tolerant permanent magnet (PM) motor electric vehicles. The proposed can consider circumferential heat transfer, variable copper loss, and uneven loss distribution. Firstly, an analytical calculation formula SC current is to separate turns from electromagnetic simulation, accuracy verified by finite element (FEA). Secondly, LPTN...
The inset-surface permanent magnet (ISPM) machine can achieve the desired electromagnetic performance according to traditional deterministic design.However, reliability and quality of may be affected by essential manufacturing tolerances unavoidable noise factors in mass production.To address this weakness, a comprehensive multi-objective optimization design method is proposed, which robust performed after design.The response surface first adopted establish objective equation.Afterward,...
