Upper Devonian carbonates of the Toc Tat Formation in the Si Phai Pass area of Dong Van District, northern Vietnam were deposited in carbonate platform, slope, and basin environments. These carbonates yield abundant conodonts indicative of the Palmatolepis nasuta , Pa. linguiformis and Pa. triangularis zones, the Frasnian–Famennian stage boundary being identified by the first occurrence of Pa. triangularis . Two positive carbo...

A quantitative rapid detection method based on loop‐mediated isothermal amplification has been developed for red‐spotted grouper nervous necrosis virus ( RGNNV ). The nested polymerase chain reaction ( PCR ) assay is the mainstream inspection of the brooder in the hatchery. In this study, a real‐time loop‐mediated isothermal amplification ( LAMP ) method has been applied for RGNNV detection, known as a high‐speed gene amplific...
