Development of efficient, cheap and recyclable catalysts for a reaction under green conditions is still very attractive topic. In this work, the cycloaddition reactions CO2 with various epoxides to form five-membered cyclic carbonates catalyzed by chitosan functionalized 1-ethyl-3-methyl imidazolium halides (CS-EMImX, X = Cl, Br) without additional solvent metal co-catalyst were achieved in high yield selectivity. The catalyst could be easily recovered reused five times catalytic activity...
Stretchable ionogels have recently emerged as promising soft and safe ionic conductive materials for use in wearable stretchable electrochemical devices. However, the complex preparation process insufficient thermomechanical stability greatly limit precise rapid fabrication application of ionogels. Here, we report an situ 3D printing method fabricating high-performance single network chemical advanced strain sensors. The consist a special cross-linking constructed by poly(ionic liquid)...
Background: SSaSS (Salt Substitute and Stroke Study), a 5-year cluster randomized controlled trial, demonstrated that replacing regular salt with reduced-sodium, added-potassium substitute reduced the risks of stroke, major adverse cardiovascular events, premature death among individuals previous stroke or uncontrolled high blood pressure living in rural China. This study assessed cost-effectiveness profile intervention. Methods: A within-trial economic evaluation was conducted from...
The effects of the oral administration Rehmannia glutinosa polysaccharide (RGP-1) on immunoregulatory properties, antioxidant activity and resistance against Aeromonas hydrophila in Cyprinus carpio L. were investigated. purified RGP-1 (250, 500 1000 μg/mL) was co-cultured with head kidney cells common carp. proliferation phagocytosis activities cells, concentration nitric oxide (NO) cytokines culture medium determined. Next, 300 carps (47.66 ± 0.43 g) randomly divided into five groups; two...
To investigate the feasibility of using Spectral CT imaging with low contrast medium in abdominal angiography (CTA). 70 consecutive patients (40 men, 42.6 ± 20.4 years; 30 women, 46.7 18.8 years) suspected focal lesions were referred to CTA exam. They randomly assigned into two groups. Group A: 35 underwent conventional scan Tube voltage 120 kVp, automatic current modulation a Noise Index 12, ASIR 30%, and injected Iohexol (350 mgI/ml). B: Imaging, 600 mA, Iodixanol (270 The optimal...
The introduction of ceramic fillers into a polymer matrix is an effective way to obtain dielectric nanocomposites with high energy storage density. However, the inorganic are difficult disperse evenly because poor compatibility, which stems from large surface difference and mismatch in constant between matrix. Polymer while maintaining breakdown strength have great potential achieve In this work, poly(dodecafluoroheptyl methacrylate) terminated thiol end group (PDFMA-SH) was synthesized via...
Printed fabrics usually have multiple colors and intricate patterns, which make it difficult to directly measure the of printed with a traditional spectrophotometer. However, hyperspectral imaging system (HIS) can since acquires spectral reflectance continuous band at every point fabric. For multiple-color fabrics, color segmentation is also very important. In this paper, measurement using HIS was implemented; an algorithm combines self-organizing map (SOM) density peaks clustering (DPC)...
An endophyte with high yield of β-mannanase, designated as Paenibacillus sp. CH-3, was isolated from black locust (Robinia pseudoacacia) seeds. The β-mannanase gene (manB) has been cloned, expressed, purified, and characterized. With an open reading frame 984 bp, the manB encodes 327 amino acid residues, which belongs to GH family 5. recombinant (ManB) apparent molecular weight 50.4 kDa optimal activity level at pH 7.0 45 °C, it is stable in range 4-9. By optimizing, temperature, isopropyl...
Abstract The Hyperspectral Imaging System can obtain the spectral response value of each pixel in a fabric sample image while being applied to color measurement. Compared with common grating System, based on Liquid Crystal Tunable Filter (LCTF) has advantages small size, high spatial resolution, and easy integration, which potential application prospects textile industry. In this article, performance LCTF for measurement was evaluated, an improved model calibrating consistency between it...
We evaluated HIV prevalence among unmarried youth in rural areas of Liangshan Prefecture southwest China over the period 2011–2015, and interactions between behaviors associated with risk. used sentinel surveillance (HSS) data for our analysis. questionnaires to investigate information aged 15 25 years performed testing. Multivariate logistic regression path analysis were applied explore associations behavioral factors related infection. A total 9536 enrolled this study, whom 2.75%...
Abstract The study examines how subordinates’ perceptions of justice in Chinese working teams are influenced by the person–team fit (or misfit) supervisor–subordinate guanxi ( SSG ). We tested our hypotheses on a sample 1,086 employees from 149 work groups one state‐owned enterprise; using combination cross‐level polynomial regression and response surface analysis. results showed that justice, terms procedural, interactional, distributive were higher when individual was congruent with...
The robot-assisted natural orifice transluminal surgery (NOTES) typically involves applying the lengthy and slender continuum instruments/manipulators to get access target lesion sites, then performs complex operations. However, due strong-nonlinearity of robotic manipulators confined tortuous anatomical paths, it's difficult establish accurate inverse kinematics (IK) model achieve precise motion control real-time shape sensing for accurately modeling their shapes. To tackle such...
Abstract This article proposed a novel approach to color measurement of single yarn using hyperspectral imaging system (HIS). Due the size yarn, it is impossible for spectrophotometers measure its directly. The HIS can acquire spectral reflectance continuous bands within region interest on sample, which achieve compared with traditional spectrophotometers. A segmented from background by matching method through adaptively setting threshold Fréchet distance values. specified that lightness...
