چکیده

Three magnetic components have been isolated in Ordovician formations of the Yangtze Paraplatform (South China Block). Two of these (Daqing A and Hongshiya B components) yield paleopoles that conform to the Carboniferous to Triassic segment of the apparent polar w•der path for South China, and are therefore interpreted as remagnetizations. The third component (declination/inclination = 30!ø/+66 ø, N = 5 sites, k = 21.4, ct95 = 17 ø) passes the fold test and is interpreted as primary (late Early Ordovician). The palcopole, at 39øS, 236øE, and the paleolatitude of 48øS support an Ordovician position of South China adjacent o

W-doped nanoporous TiO2 for high performances sensing material toward acetone gas

W-doped TiO2 with nanoporous structure was synthesized by a one-step low temperature hydrothermal method using TiOSO4 and (NH4)6H2W12O40•xH2O as titanium and tungsten sources. Structure, morphology, specific surface area and chemical state of samples were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS). W-doped nanoporo...

Relationship between Peak Milk Yield and Udder Parameters of Dehong Crossbred Dairy Buffaloes

To determine the relationship between udder traits and peak milk yield, udder parameters of 203 Dehong crossbred dairy buffaloes were measured. The average peak milk yield (kg/day) of buffaloes was 9.60 ± 2.73, with average udder dimensions of 16.51 ± 10.05, 8.07 ± 3.26, 8.68 ± 3.92, 50.74 ± 8.82, 11.38 ± 3.08, 7.18 ± 2.18 and 7.73 ± 2.15 cm for udder depth, rear udder width, rear udder height,...

Pathogenicity characteristics of Enterococcus faecium from diseased black bears

The death of several black bears at the black bear breeding base in Yunnan Pingbian Daweishan is a matter of concern. Multiple black bears exhibited decreased appetite or unusual waste, and some were soporific or suffered from vomiting and anhelation. In order to ascertain the cause of death, 16S rDNA gene sequencing and phylogenetic analysis was performed on bacteria isolated from tissue sampl...

Geographical patterns of Yunnan seed plants may be influenced by the clockwise rotation of the Simao-Indochina geoblock

Floristic patterns of seed plants in Yunnan, southwestern China, were studied to assess the relationship between the floristic geography and geological history. A database of 38 regional floristic studies covering Yunnan was used and the patterns of seed plant distributions across these regional floras were quantified at the generic level. Genera with tropical Asian distributions are the most d...

H2O2-based Green Corrosion Route to ZnO Microrods Photocatalysts on Zn Plate

Single crystal ZnO microrods are deposited on the surface of Zn plate through corrosion of Zn plate by H2O2 which is a green neutral reagent and easy to transform to H2O and O2. The structure and morphology of the obtained ZnO microrods were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy and electron diffraction. A thermodynamics mechanism was...
