This study aimed to design a novel liposome containing GA modified phosphatidylcholine lipid (GA-PC Lip) and determine its susceptibility tumor over-expressed secretory phospholipase A2 (sPLA2) anti-cancer effect compared conventional liposomes (Convention Lip). The were characterized for size, drug loading, encapsulation efficiency, stability. A 6-CF release assay was conducted assess the sensitivity of tumor-overexpressed (sPLA2). In vitro experiment, sPLA2 levels in Colo205 cell culture...
Abstract Oil-impregnated paper (OIP) bushings are essential equipment for connecting transformer windings and external busbars, the damp state of their insulating is a critical factor in determining safe stable operation. In recent years, frequency domain spectroscopy (FDS) technology has continually been utilized to evaluate bushings. However, existing FDS studies mainly focus on uniformly damped OIP bushings, with limited research nonuniform moisture states Therefore, this article predicts...
The space charge effect of transformer insulating paper will distort its internal electric field, and be more prominent under extremely complex working conditions. At present, the micromechanism transport field distortion characteristics paperboard are not clear So in this article, based on bipolar carrier (BCT) model dynamic balance model, effects high temperature, aging degree, moisture content, bent degree charges accumulation studied dc voltage by numerical simulation measured data...
Orthosiphon aristatus is a well-known folkloric medicine and herb for Guangdong soup the treatment of rheumatism in China. Eight isopimarane-type migrated pimarane-type diterpenoids (1-8), including new one with rarely occurring α,β-unsaturated diketone C-ring, were isolated from O. aristatus. Their structures determined by spectroscopic methods quantum chemical calculations. Furthermore, most abundant compound, orthosiphol K, was structurally modified modern synthetic techniques to give...
The X model is a conventional tool of frequency-domain spectroscopy (FDS) technology for assessing the insulation state oil-impregnated paper (OIP) bushings. However, accuracy and applicability are questionable because it overlooked effect nonuniform thermal aging, there no models mathematical formulas that can be applied to thermal-aged OIP To solve this issue, an enhanced proposed by considering radial axial aging model's formula was deduced initially. Then, complex relative permittivity...
Frequency-domain spectroscopy (FDS) is a nondestructive technique for moisture status evaluation of oilimpregnated paper (OIP) bushings. However, due to the lack effective models predict FDS curve OIP bushings under nonuniform moisture, it difficult establish large database characteristics analysis and heterogeneous assessment. To address this issue, established bushing FEM model an improved X based on finite element method (FEM) dielectric theory, respectively, prediction nonuniformly...
The moisture-dependent parameter in the aging kinetic model is inaccessible due to fluctuation of moisture during period bushing insulation. This significantly restricts adoption kinetics-based approaches for predicting transformer insulation lifespan. Given this issue, an improved proposed article, where influence interpreted by acceleration coefficient. To obtain involved parameters model, humidity determined recognizing moisture-related feature, which can be extracted from...
Under the combined effect of electric and temperature fields, bubbles will be formed on transformer oil-paper insulation system, which seriously endanger strength. However, current study usually divided formation motion into independent parts, lacking research whole process bubble evolution. This article experimentally investigated theoretically analyzed formation, deformation, in system explored influence extremely inhomogeneous field (EIEF) The results show that with enhancement field,...
With the surge in electrical loads and increasing voltage levels, mechanical performance thermal stability of insulating paper are facing severe challenges. However, due to lack direct scientific theories or simulation guidance, traditional inefficient “trial-and-error” experiments difficult effectively develop new types cellulose composite papers. For solving this problem, work we enhance effects nanoscale zinc oxide (nano-ZnO) on properties through molecular dynamics simulations....
Abstract BACKGROUND Nesodiprion zhejiangensis , a multivoltine sawfly, is widely distributed in south China and has caused serious damage to forests. Historically, N. management relied heavily on synthetic chemicals. To reduce the reliance chemical control, we previously isolated nucleopolyhedrovirus, NezhNPV, from deceased larvae. A subsequent pathogenicity assay confirmed its high virulence laboratory setting. RESULTS In order comprehensively examine hypothesis that NezhNPV an effective...
The moisture intrusion of high-voltage oil-immersed paper (OIP) bushing may cause insulation deterioration. Polarization and depolarization current (PDC) technology is an effective nondestructive method to evaluate the state OIP bushings' insulation. However, PDC assessment methods are difficult nonuniform status bushings. To address this issue, article studies characteristics bushings under radial distribution. Initially, by combining with laboratory measurements finite element (FEM)...
