Ten phenolic compounds were isolated from a butanol fraction of sage extracts. Their structures determined by spectral methods (NMR, MS, IR). Among them, novel compound, 4-hydroxyacetophenone-4-O-β-d-apiofuranosyl-(1→6)-O-β-d-glucopyranoside, was identified. Two test systems, DPPH free radical scavenging activity and cation ABTS•+ activity, used to evaluate their antioxidant activity. The most active found be rosmarinic acid luteolin-7-O-β-glucopyranoside. Keywords: Sage; Salvia officinalis;...
The China Fusion Engineering Test Reactor (CFETR) is the next device in roadmap for realization of fusion energy China, which aims to bridge gaps between experimental reactor ITER and demonstration (DEMO). CFETR will be operated two phases. Steady-state operation self-sufficiency key issues Phase I with a modest power up 200 MW. II DEMO validation over 1 GW. Advanced H-mode physics, high magnetic fields 7 T, frequency electron cyclotron resonance heating lower hybrid current drive together...
This study investigated the effect of cold helium plasma treatment on seed germination, growth and yield wheat. The effects different power germination treated wheat seeds were studied. We found that 80 W could significantly improve potential (6.0%) rate (6.7%) compared to control group. Field experiments carried out for with plasma. Compared control, plant height (20.3%), root length (9.0%) fresh weight (21.8%) improved at seedling stage. At booting stage, height, length, weight, stem...
This study investigated the effect of cold plasma seed treatment on tomato bacterial wilt, caused by Ralstonia solanacearum (R. solanacearum), and regulation resistance mechanisms. The 80W germination, plant growth, nutrient uptake, disease severity, hydrogen peroxide (H2O2) concentration activities peroxidase (POD; EC 1.11.1.7), polyphenol oxidase (PPO; 1.10.3.2) phenylalanine ammonia lyase (PAL; 4.3.1.5) were examined in plants. Plasma increased to R. with an efficacy 25.0%. significantly...
Abstract The northeast region of China is an important grain‐growing area. However, severe soil salinization in the impairs plant production. In present study, organic fertilizer application (composted poultry manure) was evaluated as a potential strategy for remediating saline–alkali and promoting rice growth. Following continuous 4 years, contents basic cations, including sodium (Na + ) chlorine cations (Cl − ), decreased significantly ( p < .05) (soil Na from 24.3 mg kg −1 to 21.8 Cl ‐...
As urbanization increases, the city continues to interfere with an already-fragile oasis eco-environment in arid areas. This paper proposes a synthesised evaluation index system regarding level from perspectives of demographic, economic, spatial, and social urbanization. The was characterised terms its level, endowment, pressure response. Moreover, coupling coordination degree model established respect based on panel data three county-level cities 14 counties Kashgar metropolitan area 1999...
New capabilities including radio-frequency (RF) powers and diagnostics have been developed since the last IAEA meeting. Divertor performance has systematically assessed for both single null double configurations with normal reversed BT directions to address asymmetries correlated classic drift issues of heat load on divertor plates. 1 MW lower hybrid wave power injection produced fully non-inductive diverted plasma discharges. Such discharges readily extended well over min duration. With...
A flat-field extreme ultraviolet (EUV) spectrometer working in the 20-500 Å wavelength range with fast time response has been newly developed to measure line emissions from highly ionized tungsten Experimental Advanced Superconducting Tokamak (EAST) a divertor, while monitoring of light and medium impurities is also an aim present development. focal plane for spectral image detection made by laminar-type varied-line-spacing concave holographic grating angle incidence 87°. back-illuminated...
This study explored the effects of cold plasma treatment on seed germination, plant growth, and peanut yield. Cold improved germination seedling 120 W produced best effect. Germination potential rate were markedly raised by 150% 21%, respectively. was accelerated uniformity emergence improved. The apparent contact angle decreased 53%.

In the last few years, long-pulse H-mode plasma discharges (with small edge-localized modes and normalized beta, βN ~ 1) have been realized at Experimental Advanced Superconducting Tokamak (EAST). This paper reports on high-βN (>1.5) in 2015 EAST campaign. The characteristics of these plasmas presented a database. Analysis experimental limit has revealed several main features typical discharges. Firstly, efficient, stable high heating power is required. Secondly, control impurity radiation...
An atmospheric-pressure non-thermal plasma jet excited by high frequency alternating current using nitrogen is developed and the electron density in active region of this investigated two different methods optical emission spectroscopy, Stark broadening, irradiance intensity method. The method shows that average about 1020/m3 which slightly smaller than broadening However, trend change with input power obtained these consistent.
Abstract Application of plant growth‐promoting rhizobacteria (PGPR) has been considered as an environmentally friendly method for crop yield promotion well disease management. Efforts have devoted to unraveling mechanisms involved in bacteria–plant and bacteria–pathogen interactions. However, little is known on the effect interaction among PGPR, soil, plant. We compared growth capacity biofertilizer Ning Shield, a consortium bacterial preparation used (BF), its mixture with compost...
