Integrated detrital rutile and detrital zircon ages: a new perspective on the tectonic evolution of South China.

Paleogeographic reconstructions are of key importance for understanding the history of continental breakups and amalgamations during Earth's history. A special case is the history of the Asian continent, which, compared to other continents, consists of several large cratons and numerous smaller continental blocks. The history of the assembly of South China remains controversial in terms of the timing, Late Neoproterozoic or Early Paleozoic, and the participating continental blocks, e.

Mixed selling of different poultry species facilitates emergence of public-health-threating avian influenza viruses.

Live poultry markets (LPMs) are regarded as hubs for avian influenza virus (AIV) transmission in poultry and are a major risk factor in human AIV infections. We performed an AIV surveillance study at a wholesale LPM, where different poultry species were sold in separate stalls, and nine retail LPMs, which received poultry from the wholesale LPM but where different poultry species were sold in one stall, in Guangdong province from 2017 to 2019. A higher AIV isolation rate was observed at the retail LPMs than the wholesale LPM.

Increased public health threat of avian-origin H3N2 influenza virus caused by its evolution in dogs.

Influenza A viruses in animal reservoirs repeatedly cross species barriers to infect humans. Dogs are the closest companion animals to humans, but the role of dogs in the ecology of influenza viruses is unclear. H3N2 avian influenza viruses were transmitted to dogs around 2006 and have formed stable lineages.

Nanostructured transition-metal phthalocyanine complexes for catalytic oxygen reduction reaction.

Oxygen reduction reaction (ORR) plays a key role in the field of fuel cells. Efficient electrocatalysts for the ORR are important for fuel cells commercialization. Pt and its alloys are main active materials for ORR.

Control of fault plane geometry on the formation of a normal fault-related anticline: an experimental approach.

In one of the largest oil-gas fields in Daqing, China, the anticlines are important structures that hold natural gas. The origin of the symmetric anticlines, which have bends on both the limbs, remains under debate. This is especially true in the case of the anticline in Xujiaweizi (XJWZ), which has recently been the focus of gas exploration.

Seroprevalence of Toxoplasma gondii infection in police dogs in Shenyang, Northeastern China.

In recent years, worldwide surveys of Toxoplasma gondii infection in dogs have been reported. However, only limited surveys of T. gondii infection in police dogs have been available, including China.

Seroprevalence of Toxoplasma gondii in slaughtered horses and donkeys in Liaoning province, northeastern China.

Background: Toxoplasma gondii is an important zoonotic pathogen infecting humans and almost all warm-blooded animals. The most common sources of human infection are ingestion of tissue cysts in raw or undercooked meat. However, limited information is available about T.

Seroprevalence of Toxoplasma gondii infection in slaughtered chickens, ducks, and geese in Shenyang, northeastern China.

Background: In recent years, investigations of Toxoplasma gondii infection in poultry (chickens, ducks, and geese) have been reported worldwide, including China. However, little is known about the prevalence of T. gondii infection in poultry in northeastern China.

Seroprevalence of Toxoplasma gondii infection in domestic sheep in Liaoning Province, northeastern China.

There is a lack of information regarding the prevalence of Toxoplasma gondii infection in sheep from northeastern China. In the present study, serum samples from 566 domestic sheep were collected from Liaoning Province, northeastern China, to investigate the prevalence of T. gondii antibodies using an indirect hemagglutination antibody test.

Seroprevalence of Toxoplasma gondii infection in pet dogs in Shenyang, northeastern China.

In recent years, surveys of Toxoplasma gondii infection in dogs have been reported throughout the world, including China. However, information is lacking regarding the prevalence of T. gondii infection in pet dogs in northeastern China.

Biosorption of copper and lead ions by waste beer yeast.

Locally available waste beer yeast, a byproduct of brewing industry, was found to be a low cost and promising adsorbent for adsorbing copper and lead ions from wastewater. In this work, biosorption of copper and lead ions on waste beer yeast was investigated in batch mode. The equilibrium adsorptive quantity was determined to be a function of the solution pH, contact time, beer yeast concentration, salt concentration and initial concentration of copper and lead ions.

Copper(II) and lead(II) removal from aqueous solution in fixed-bed columns by manganese oxide coated zeolite.

The ability of manganese oxide coated zeolite (MOCZ) to adsorb copper and lead ions in single- (non-competitive) and binary- (competitive) component sorption systems was studied in fixed-bed column. The experiments were applied to quantify particle size, bed length, influent flow rate and influent metal concentration on breakthrough time during the removal of copper and lead ions from aqueous solutions using MOCZ column. Results of fixed-bed adsorption showed that the breakthrough time appeared to increase with increase of the bed length and decrease of influent metal concentration, but decreased with increase of the flow rate.
