New record and dietary ecology of a poorly-known treefrog, Yu, Hui, Hou, Wu, Rao & Yang, 2019 (Anura, Rhacophoridae) in Vietnam.

Background: The White-lipped Treefrog Yu, Hui, Hou, Wu, Rao & Yang, 2019 was previously confused with (Blyth, 1852). Records of from Yunnan (China), Vietnam and Thailand were recognised as a misidentification and this taxon was subsequently described as a new species, based on morphological and molecular evidence. This species is currently known from southern China, Thailand, Laos and Vietnam.

Investigations on corrosion resistance of steel coated with chromium-free ZTM conversion coating.

Chromium-free conversion coatings based on Zr/Ti/Mo (ZTM) compounds via chemical conversion technology were investigated to improve the corrosion performance of SPCC-JISG 31 steels. A preliminary study was carried out to evaluate the influences of critical parameters, including the concentrations of active species Zr, Ti and Mo, and the conversion bath's pH, on the protective efficiency using a Statistical design of experiments (DoE) methodology. Passivation layer with compositional Mo, Ti and Zr elements has been employed on the steels by dipping in mixed solutions containing 17 g/l NaMoO, 1 g/l KTiF and 7 g/l KZrF under pH = 5.

Morphological Characteristics of the Vietnamese Adult Human Acetabulum Using Multiplanar Reconstruction Computed Tomography in Total Hip Replacement Surgery.

Background: The anatomical parameters of the acetabulum vary among races and geographical regions.

Evolution of habitat preference in 243 species of Bent-toed geckos (Genus Gray, 1827) with a discussion of karst habitat conservation.

Understanding the processes that underpin adaptive evolutionary shifts within major taxonomic groups has long been a research directive among many evolutionary biologists. Such phenomena are best studied in large monophyletic groups that occupy a broad range of habitats where repeated exposure to novel ecological opportunities has happened independently over time in different lineages. The gekkonid genus is just such a lineage with approximately 300 species that range from South Asia to Melanesia and occupy a vast array of habitats.
