After partial substitution of V2O5 in V2O5–WO3/TiO2 by metal oxide (MxOy, M = Fe, Co, Ni, Cu, Sr, La, and Ce), the NO conversions for the MxOy–V2O5–WO3/TiO2 catalysts (M-VW) showed the following sequence: Co–VW > Fe–VW > Sr-VW Ce-VW La-VW > VW > Ni-VW > Cu-VW. The reduction activities for almost all the M-VW catalysts were enhanced at reaction temperature >400 8C, but only the Co-VW catalyst showed an increased activity at temperature <400 8C. Among the M-VW catalysts tested, the Co-VW sample had the highest catalytic activity with a temperature range of 300–550 8C for more than 90% NO removal at a GHSV of 60 000 h1. Moreover, the Co-VW sample exhibited high space- velocity, H2O and SO2 resistance, and low N2O yield. Co partial substitution for V in the VW led to more Lewis acid sites and Brønsted acid sites, and an obvious increase in the ratio of the adsorbed oxygen to the lattice oxygen from 12.74% for VW to 36.73% for Co-VW. The increased adsorbed oxygen and Lewis and Brønsted acid sites contributed to the improved SCR activity of the Co-VW sample.

A new molecular-baiting method was studied by retrieving targeted gene fragments from an oligonucleotide microarray bait after hybridization. To make the microarray bait, 70-mer oligonucleotides that were designed to specifically represent the SSA1 gene of Saccharomyces cerevisiae were printed on the slide. Samples of the Saccharomyces cerevisiae mRNA were extracted and labeled by the RD-PCR (Restriction Display PCR) method using the Cy5-labelled universal primer, then applied for hybridization. The sample fragments that hybridized to the microarray were stripped, and the eluted cDNAs were retrieved and cloned into the pMD 18-T vector for transformation, plasmid preparation, and sequencing. BLAST searching of the GenBank database identified the retrieved fragments as being identical to the SSA1 gene (from 2057-2541bp). A new method is being established that can retrieve the sample fragments using an oligo-microarray-bait.

To make the microarray bait, 70-mer oligonucleotides that were designed to specifically represent the SSAl gene of Saccharomyces cerevisiae were printed on the slide.

This study focused on the buildings, wharves, and parks of the coastal space of Chongqing based on the ten-year construction draft plan of the alternate capital. From an investigation of these three components according to their type, structure, terrain, function, spatial layer, and so on, the following conclusions were drawn: The coastal space of Chongqing is composed of three different layers. The first and second layers consisted of the two-river intersection basin with the transportation and commemorative space at the center, the Yangtze River basin with the commercial space at the center, and the Jialing River with the military and recreational space at the center. The third-layer is centered around the commemorative space. The coastal space of Chongqing manifested the limitations of the times, its traditionality, and an integrated development process.

The chigger mite Leptotrombidium sialkotense is one of the 6 main vectors of scrub typhus in China. Before present study, L. sialkotense was found in some parts of Hunan province, China with a narrow geographical distribution. During field investigation 2016-2017, we found L. sialkotense in Jingha, southern Yunnan, China. Of 15 small mammal host species, L. sialkotense were collected from 6 species of the hosts. Rattus brunneusculus was a dominant host of L. sialkotense, from which 98.3% of the mites were collected. The chigger mite showed a relatively high infestation prevalence (PM=11.7%) and mean abundance (MA=0.5) in comparison with the rest 5 host species. These results reveal a certain host specificity of L. sialkotense to a rat R. brunneusculus. The mite L. sialkotense showed an aggregated distribution on the host (P<0.05). A positive correlation observed between L. sialkotense and the body length of hosts. There was a positive interspecific association between L. sialkotense and 2 other dominant vectors, L. deliense and L. scutellare.
