An accurate, efficient, and economical identification technology for black twig borer based on species-specific cytochrome C oxidase subunit I PCR assay.

Xylosandrus compactus (Eichhoff) (Coleoptera: Curculionidae, Scolytinae) is a worldwide invasive species that causes huge economic loss and environmental damage in many countries. Traditional morphological characteristics make it hard to identify scolytines due to their tiny size. Besides, the intercepted insect samples are incomplete, and the limitation of insect (larvae and pupae) morphology makes morphological identification more difficult.

First report of southern blight caused by on Spotted laurel () in China.

, also known as spotted laurel, is a woody, broadleaf, evergreen shrub with variegated leaves in the Garryaceae family, widely used in urban parks, green spaces and landscaping. In October 2019, an outbreak of a disease with southern blight symptoms was observed on planted as a green barrier in Kunshan city, Jiangsu province of China (N31°32'37", E120°00'41"). The disease incidence was estimated up to 30%.

Condensate Oil-Tolerant Foams Stabilized by an Anionic-Sulfobetaine Surfactant Mixture.

Foams are widely used to remove liquid loading at the bottom of gas wells to improve natural gas production. However, it becomes ineffective when a gas well contains a large amount of hydrocarbon condensate because oil will rupture the foams. In this work, condensate oil-tolerant foams were developed and stabilized by a mixture of cocamidopropyl hydroxyl sulfobetaine (CHSB) and sodium dodecyl sulfate (SDS).

CO-switchable foams stabilized by a long-chain viscoelastic surfactant.

Smart foams sensitive to external stimulation have gained increasing attention recently. However, reversibly switchable CO foams have been less documented. In this work, a novel kind of CO-switchable foams was developed using a long-chain cationic surfactant, N-erucamidopropyl-N,N-dimethylammonium bicarbonate (UCAMPM⋅H), as both the foaming agent and stabilizer.

Diagnostic performance of noninvasive fractional flow reserve derived from coronary computed tomography angiography in ischemia-causing coronary stenosis: a meta-analysis.

Purpose: Fractional flow reserve based on coronary computed tomographic angiography (CCTA; FFR) can evaluate functional severity in coronary artery disease (CAD). This study investigated the diagnostic value of FFR for determining CAD severity.

Materials And Methods: Medline, Cochrane, EMBASE, and Google Scholar databases were searched until June 16, 2016 using the following search terms: fractional flow reserve, coronary computed tomography angiography, myocardial ischemia.
