The detection of fastener defects is an important task in railway inspection systems, and it frequently performed to ensure the safety train traffic. Traditional usually operated by trained workers who walk along lines search for potential risks. However, manual very slow, costly, dangerous. This paper proposes automatic visual system detecting partially worn completely missing fasteners using probabilistic topic model. Specifically, our method able simultaneously model diverse types with...
The application of cold plasma in sterilization a root canal tooth has recently attracted great attention. In this paper, reliable and user-friendly plasma-jet device, which can generate inside the canal, is reported. be touched by bare hands directed manually user to place it into for disinfection without causing any painful sensation. When He/O <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> (20%) used as working gas, rotational...
A rapid, sensitive, and robust CE-MS method has been developed for the determination of tetracycline, oxytetracycline, chlortetracycline in milk. Field-amplified sample stacking with electromigration injection (FASS-EMI) was used online concentration tetracyclines. The conditions separation, MS detection, were systematically optimized. optimum buffer composition 35 mM Tris, 1.1% formic acid, 5% methanol, 15% ACN. By using field-enhanced (FESI)-EMI stacking, sensitivity increased six- to...
The problems of adulteration and mislabeling are very common in the food industry. Laser-induced breakdown spectroscopy (LIBS) coupled with chemometric methods has many intrinsic advantages on analysis various materials. In this work, several algorithms, i.e., principal component (PCA), decision tree (DT), random forest (RF), partial least squares discriminant (PLS-DA), linear (LDA), support vector machine (SVM), were carried out assisted by LIBS technology to study classification...
Antimony (Sb) in soil is attracting attention the research community due to its potential toxicity and carcinogenicity. Traditional methods of detecting Sb lack ability rapid nondigestion analysis, which hinders their development application. Moreover, it still a challenge for laser-induced breakdown spectroscopy (LIBS) detect weak intensities intense interference spectral lines. Here, LIBS, assisted with fluorescence (LIBS-LIF), was used selectively enhance Sb's characteristic lines under...
Enterococcus faecalis (E. faecalis) is a microorganism that can survive extreme challenges in obturated root canals. The aim of this study was to evaluate the efficacy non-thermal atmospheric pressure plasma plume against E. vitro. A jet device which could generate cold carrying peak current 300 mA used. antibacterial and its biofilm under different conditions detected. Staphylococcus aureus (S. aureus) also evaluated. After treatment, average diameter inhibition zone on S. 2.62±0.26 cm...
Quality and safety of food are two the most important matters in our lives. Wheat is one products modern agricultural processing industry. Issues mislabeling adulteration increasingly serious concern grain market. They threaten credibility producers traders rights consumers. Therefore, it very significant to guarantee degree wheat flour. In this work, different spectral peak recognition methods, i.e., artificial automatic recognition, carried out study problem Three grades flour from...
Nutrient profile determination for plant materials is an important task to determine the quality and safety of human diet. Laser-induced breakdown spectroscopy (LIBS) atomic emission spectrometry material component analytical technique. However, quantitative analysis using LIBS usually suffers from matrix effects nonlinear self-absorption. To overcome this problem, a hybrid model partial least squares-artificial neural network (PLS-ANN) was used detect compositions in air. Specifically,...
Laser induced breakdown spectroscopy (LIBS) is an emerging tool with rapid, nondestructive, green characteristics in qualitative or quantitative analyses of composition materials. But LIBS has its shortcomings detect limit and sensitivity. In this work, heavy metal Cu Gannan Navel Orange, which one famous fruits from Jiangxi China, was analyzed. view LIBS's limit, it difficult to determinate metals natural fruits. nine orange samples were pretreated 50-500 μg/mL solution, respectively....
Qualitative analysis using handheld laser-induced breakdown spectroscopy (HH-LIBS) usually suffers from spectral fluctuation.
To predict the nutrition and safety of agricultural products by laser-induced breakdown spectroscopy (LIBS), heavy metal Cd in rice was selected as an analytical target. Mature grain samples from 40 growing geographical areas around Poyang Lake were picked on-site processed grinding to obtain edible rice. The content determined graphite furnace atomic absorption spectrometry, pellets detected LIBS. risk intake estimated target hazard quotient Chinese National Standard. Moreover, classified...
Abstract In this study, a novel multi‐stimulus responsive RGB fluorescent organic molecule, RTPE‐NH 2 , was designed and synthesized based on the combination of aggregation‐induced emission tetraphenylethylene (TPE) luminophore acid‐responsive molecular switch Rhodamine B. exhibits behavior, as well UV irradiation‐stimulus acid‐stimulus fluorescence properties. It could emit orange‐red (R), green(G), blue(B) light in both solution PMMA film under 365 nm excitation. The dark through‐bond...
This paper describes a reinvestigation into the putative role of Ziegler process during polymerization acrylonitrile by compound FeEt2(2,2'-dipyridyl)2. For this very efficient initiator, coordination is reported to be precondition for polymerization, seemingly more compatible with than conventional radical process. Consistent previous observations, we do indeed find evidence sequence events in which displaces dipy ligand FeEt2(dipy)2, coordinating via CC bond η2-fashion rather nitrogen....
