Novel SO3H-functionalized ionic liquids bearing two alkyl sulfonic acid groups in the imidazolium cations were designed and successfully applied as catalysts for one-pot Fischer indole synthesis water medium. The sequence of catalytic activity observed transformation was good agreement with Brønsted acidity order determined by Hammett method. Various types indoles from single-carbonyl ketones/aldehydes cyclohexandiones provided 68–96% yields using system [(HSO3-p)2im][HSO4]/H2O. products...
Abstract A novel one‐pot Fischer indole synthesis approach has been developed by using Brønsted acidic ionic liquids as dual solvent‐catalysts. Yields of 83–97 % were obtained after reaction in BMImHSO 4 at 70–110 °C 0.5–6 h, and exclusive formation 2,3‐disubstituted indoles was observed the alkyl methyl unsymmetrical ketones. The produced could be conveniently separated from mixture without any volatile organic solvents, readily reused efficiency loss simple treatment involving only 1...
The microbes residing in ruminant gastrointestinal tracts play a crucial role converting plant biomass to volatile fatty acids, which serve as the primary energy source for ruminants. This tract comprises foregut (rumen) and hindgut (cecum colon), differ structures functions, particularly with respect feed digestion fermentation. While rumen microbiome has been extensively studied, cecal remains much less investigated understood, especially concerning assembling microbial communities...
Ammonia is one of the most important toxic metabolites in intestine animals. It can cause intestinal damage and associated diseases through different endogenous or exogenous stimuli. However, definition harmful ammonia concentration molecular mechanism - induced epithelial injury remain unclear. In this study, we found that viability porcine IPEC-J2 cells significantly decreased with increase NH4Cl dose (20-80 mM). (40 mM NH4Cl) increased expression level transporter RHCG disrupted barrier...
In satellite scheduling system, one of the most important issues is task scheduling. Most existing algorithms focused on scenario normal tasks with fixed priority and don't consider emergency tasks. However, in system have independent arrival time execution deadline. To deal this challenge, we propose model, based rolling-horizon optimization (RHO) strategy to manage construct a model multiple constraint conditions. decompose into four parts, including target priority, imaging TT&C (track,...
<title>Abstract</title> Background The microbes residing in ruminant gastrointestinal tracts convert plant biomass to nutritious volatile fatty acids, the primary energy source for ruminants. Ruminants´ tract comprises a foregut (rumen) and hindgut (cecum colon), each with contrasting structures functions anaerobic digestion. With most previous studies focusing on rumen microbiome, cecal microbiome is much less investigated understood, including assembling microbial communities overriding...
SaaS(Software as a Service) has recently made great impact on the software industry and changed traditional lifetime of software. To obtain benefit SaaS, more products have been converted into SaaS model, including business workflow management systems (BWfMS). Compared with BWfMSs, oriented BWfMSs introduce new set features which demand architectural design for BWfMSs. Although several developed, study from an perspective is still missing. The main contributions this paper are: 1) according...
In the models of piezoelectric actuator (PEA) systems, hysteresis effects are often described by concise Bouc–Wen models; however, these nonlinear and non-smooth because existence terms which involve absolute-value function. particular, a challenging control problem is posed when, due to properties certain materials, such high order. This has been rarely studied. article proposes use approximated scalar sign function (ASSF), numerically stable differentiable function, represent with...
The step size of least mean square (LMS) algorithm is significant for its performance. To be specific, small can get excess error but results in slow convergence. However, large may cause instability. Many variable (VSSLMS) algorithms have been developed to enhance the control In this paper, a new VSSLMS was proposed based on Kwong’s evaluate robustness. approximate analysis dynamic and steady-state performance given. An active vibration system piezoelectric cantilever beam established...
The running process of rolling bearing is often nonlinear and abnormal. Therefore, this paper uses the method which combing KICA LS-SVM to achieve bearings' fault monitoring classification. Firstly, vibration signal mapped into high dimensional space by using kernel methods, constructing I2, Ie2 SPE indicator in monitor data. And then when occurred, extracting time domain wavelet energy features construct multi-domain mixed feature set, input vector for Experimental results show can complete...
Tris(1,3-dichloro-2-propyl) phosphate (TDCIPP) has been frequently detected in the aquatic environments and organisms, several studies have reported that great concentrations of TDCIPP could cause malformation zebrafish (Danio rerio) embryo/larvae. However, chronic effects environmentally relevant on bone phenotype remain unclear. In this study, 1-month-old crucian carp (Carassius auratus) were exposed to 0, 500, or 5000 ng/L for 18 months, skeletal evaluated. The results demonstrated...
The rolling bearing is one of the most important and widely used parts in rotating machinery. It necessary to establish a reliable condition monitoring program which can avoid serious fault runtime diagnose failure timely accurately when it happens. This paper puts forward diagnosis method based on PSO-SVM mixed-feature. Firstly, we extract features time domain, frequency order quenfrency domain. Secondly, select both Support Vector Machine (SVM) parameters by Particle Swarm Optimization...
Abstract The liquid reaction in a submerged top‐blow agitation process was studied using planar laser‐induced fluorescence (PLIF) technology based on the principle of quenching. effects were analyzed degree θ ( t ) and time 95 under different conditions. results show that decreases obviously for an increase air flow rate depth spray gun. injection position Fe 3+ has great influence process; is also other blowing conditions when injected at bottom. bottom higher than top position; increasing...
