At present, the regeneration agent with mineral oil as main component is widely used. However, its strong volatility, nonrenewability, and other shortcomings restrict development of technology. In this study, waste vegetable was used to prepare regenerated aging asphalt. The change in microstructure asphalt explored content time. results showed that addition could effectively supplement contents saturates aromatics, inhibit oxidation aromatics into asphaltene resin. When time 60 min 7.0%,...

Purpose – This paper seeks to present a prognostics approach using the Mahalanobis distance (MD) method predict reliability of multilayer ceramic capacitors (MLCCs) in temperature‐humidity‐bias (THB) conditions.

Leptin is an adipocytokine that primarily secreted by white adipose tissue, and it contributes to the pathogenesis of neuropathic pain in collaboration with N-methyl-D-aspartate receptors (NMDARs). Functional NMDARs are a heteromeric complex comprise two NR1 subunits NR2 subunits. NR2A preferentially located at synaptic sites, NR2B enriched extrasynaptic sites. The roles contribution leptin not clear. present study examined whether important role was related or NMDARs. We used rat model...

Abstract A liquid crystalline thermoset (LCT), 4,4′‐diglycidyloxy‐α‐methylstilbene/sulfanilamide, is studied by dynamic mechanical and vapor sorption measurements. Sub‐ T g transitions are assigned to the specific segmental motions through molecular modeling used define environmental temperatures for study of water transport properties in LCT. The variation moisture with amine‐epoxy ratio reveals that crosslink density local concentration polar groups play key role determining both...

Abstract Eupafolin is a phyto compound of flavone that exerts anti‐inflammatory, antioxidant, and antiproliferative properties. The main purpose this study to examine the antidiabetic effect eupafolin on nicotinamide–streptozotocin (STZ)‐induced Type 2 diabetes (T2D) rats. After nicotinamide (120 mg/kg) treatment, STZ (60 was administrated intravenously induce T2D. Rats with fasting blood glucose (FBG) > 200 mg/dL are chosen for 7 days after T2D induction. treatment continued another 15...

Purpose This paper seeks to investigate the electronics industry's reaction environmental regulations specifically in terms of lead‐free solders and halogen‐free flame‐retardants (FRs). Design/methodology/approach work achieves its objective by discussing various international pertaining manufacturing relating industry reactions those regulations. It also provides market trends related lead‐ products. The is pursuing FRs, part due However, includes examples how successful implementing...

The ban of lead in consumer-based electronics by many countries has resulted a dramatic reduction the availability electronic components with tin-lead terminations. With uncertainty associated lead-free reliability and issues mixing solder solder, medical, defense, aerospace equipment manufacturers are examining some cases implementing reprocessing practices to convert terminations tin-lead. For area array packages, practice is referred as reballing. While reballing been used for part...

Aspirin is the only drug proven to reduce saphenous vein graft (SVG) failure, but aspirin resistance (ASA-R) frequently occurs after off-pump coronary artery bypass grafting (OPCAB). The factors, mechanism, and best means for preventing and/or treating ASA-R have not been established. This study hypothesizes that thrombin production during OPCAB stimulates this acquired ASA-R.A nonrandomized prospective cohort of 255 patients (n=465 SVG) who underwent with varied use aprotinin (21%)...

Objective . To determine whether bile acids (BAs) affect respiratory functions through the farnesoid X receptor (FXR) expressed in lungs and to explore possible mechanisms of BAs-induced disorder. Methods Primary cultured alveolar epithelial type II cells (AECIIs) rat were treated with different concentrations chenodeoxycholic acid (CDCA) presence or absence FXR inhibitor Z-guggulsterone (GS). Then, expression nuclei AECIIs was assessed by immunofluorescence microscopy. And ultrastructural...

Corn stover (CS) is mainly composed of three parts: pith (CSP), rind (CSR), and leaf (CSL). These parts have different lignocellulosic constituents structural properties. Herein, biosorbents derived from individual corn were prepared in an effort to determine the significance each constituent for multipollutant removal. In this study, SEM, BET, XRD, FTIR, XPS, fibre composition, contact angle measurements used characterize analyse physical chemical properties components CS study their...

Abstract Atherosclerosis is an age‐related pathological process associated with elevated levels of legumain in plaques and plasma. However, the underlying mechanisms remain unclear. The aim this study was to investigate role progression atherosclerotic plaques, a particular focus on functional phenotypic changes CD4 + T cells. Apolipoprotein E‐deficient ( Apoe −/− ) mice were crossed legumain‐deficient Lgmn generate mice. cells accumulated fed high‐fat diet. Deletion attenuated deposition...

Oil spillage is a serious problem all over the world. Usage of agricultural byproducts for raw materials in biosorbents applications promising way to solve this problem. In paper, green biotechnological procedure has been developed using Phanerochaete chrysosporium produce an oil-sorbent from corn stalk and cob. Without fungal modification, maximum sorption oil by cob was 6.95 g/g 4.14 g/g, whereas treatment with increased up 9.03 7.69 respectively. SEM XRD were applied characterization...

This study identified the generation and emission nodes of volatile organic compounds (VOCs) in metal packaging industry, analyzed VOCs concentration species from different production processes, accounted for secondary pollution through maximum incremental reactivity method modified fractional aerosol coefficient method. The results indicated that main were benzenes, alcohols, ketones, esters, benzenes alcohols contributed more types processes nodes, whereas ketones esters less. was...
