To Save Pangolins: A Nutritional Perspective.

Pangolins are one of the world's most trafficked mammals. Since pangolins are highly adapted to ants and termites, they are important for controlling forest termite infestations. In addition to their ecological value, pangolins have economic and medicinal value.

Etiology and genetic evolution of canine coronavirus circulating in five provinces of China, during 2018-2019.

As the outbreaks of COVID-19 in worldwide, coronavirus has once again caught the attention of people. Canine coronavirus is widespread among dog population, and sometimes causes even fatal cases. Here, to characterize the prevalence and evolution of current circulating canine coronavirus (CCoV) strains in China, we collected 213 fecal samples from diarrheic pet dogs between 2018 and 2019.

[The ground reflectance spectrum retrieval from ETM images].

Retrieval of ground reflectance spectrum from satellite sensor digital count requires knowledge of the atmospheric conditions. Images of spectral radiance from ground-atmosphere system recorded by the multi-spectral imager ETM which boarded Landsat-7 sensor can retrieve the ground reflectivity spectrum. The uncertainty of reflectance spectrum retrieval is no more than 17% at the band 1 of ETM, and less than 10% at the band 2 and 3 of ETM.

[Study of fluorescence spectra of starch suspension].

To achieve detection, monitoring and automation of starch graft copolymerzation, the investigation was carried out according to the luminescence of free radical produced in the reaction. The investigation on the fluorescence spectra of starch-water suspension excited by ultraviolet light and its characteristics contributes to the study of the characteristics and mechanisms of free radical coming into being, emitting and disappearing. The experimental results indicate that starch-water suspension can emit fluorescence, whose peak wavelength is about 339 nm.
