First detection and characterization of genetically divergent canine calicivirus strains in domestic dogs in China.

Canine calicivirus (CaCV) belongs to the family, which invades multiple host species. Notably, there are distinct serological and genetic differences between CaCV and other caliciviruses. However, the genome data for only 13 strains of CaCV have been recorded.

Enhanced chromium and nitrogen removal by constructing a biofilm reaction system based on denitrifying bacteria preferential colonization theory.

Understanding the developmental characteristics of microbial communities in biofilms is crucial for designing targeted functional microbial enhancements for the remediation of complex contamination scenarios. The strong prioritization effect of microorganisms confers the ability to colonize strains that arrive first dominantly. In this study, the auto-aggregating denitrifying bacterial Pseudomonas stutzeri strain YC-34, which has both nitrogen and chromium removal characteristics, was used as a biological material to form a stable biofilm system based on the principle of dominant colonization and biofortification.

Nitrogen removal intensification of biofilm through bioaugmentation with Methylobacterium gregans DC-1 during wastewater treatment.

The increasing concern for environmental remediation has led to a search for effective methods to remove eutrophic nutrients. In this study, Methylobacterium gregans DC-1 was utilized to improve nitrogen removal in a sequencing batch biofilm reactor (SBBR) via aerobic denitrification. This bacterium has the extraordinary characteristics of strong auto-aggregation and a high ability to remove nitrogen efficiently, making it an ideal candidate for enhanced treatment of nitrogen-rich wastewater.

Systematic investigation of simultaneous copper biosorption and nitrogen removal from wastewater by an aerobic denitrifying bacterium of auto-aggregation.

Finding effective methods for simultaneous removal of eutrophic nutrients and heavy metals has attracted increasing concerns for the environmental remediation. Herein, a novel auto-aggregating aerobic denitrifying strain (Aeromonas veronii YL-41) was isolated with capacities for copper tolerance and biosorption. The denitrification efficiency and nitrogen removal pathway of the strain were investigated by nitrogen balance analysis and amplification of key denitrification functional genes.

The Quadratic Constitutive Model Based on Partial Derivative and Taylor Series of Ti6242s Alloy and Predictability Analysis.

To solve the problem of insufficient predictability in the classical models for the Ti6242s alloy, a new constitutive model was proposed, based on the partial derivatives from experimental data and the Taylor series. Firstly, hot compression experiments on the Ti6242s alloy at different temperatures and different strain rates were carried out, and the Arrhenius model and Hensel-Spittel model were constructed. Secondly, the partial derivatives of logarithmic stress with respect to temperature and logarithmic strain rate at low, medium and high strain levels were analyzed.

Evaluation of Four Commonly Used DNA Barcoding Loci for Species Identification.

plants have been used as medicinal plants for a long time in China. Traditional techniques such as morphological, microscopic, and chemical identification methods all have limitations in the species identification of . For the sake of drug safety, four DNA barcodes (, ITS, , and ) were assessed for Chinese plants using a total of 121 individuals from 33 species.

Enhanced North Pacific subtropical gyre circulation during the late Holocene.

The North Pacific Subtropical Gyre circulation redistributes heat from the Western Pacific Warm Pool towards the mid- to high-latitude North Pacific. However, the driving mechanisms of this circulation and how it changed over the Holocene remain poorly understood. Here, we present alkenone-based sea surface temperature reconstructions along the Kuroshio, California and Alaska currents that cover the past ~7,000 years.

The complete chloroplast genome of var. (Lamiaceae) from Guilin, China, a potential medicinal plant.

var. is one of the traditional medical herbs which has the potential for multiple diseases' treatment. In this study, the complete chloroplast genome sequence of var.

Characterization of the complete chloroplast genome of (Asparagaceae).

As a kind of rare plant with important medicinal value and breeding value, usually grow in dark and damp places. In this study, we reported the complete chloroplast genome of . We used a variety of bioinformatics analysis methods to analyze and visualize the chloroplast genome and phylogenetic relationships.

The complete chloroplast genome of (Euphorbiaceae), a commonly used medicinal plant in China.

Plants in the genus have been widely used as herbal medicine, and for ornamental horticulture and biofuel production. In this study, we report the complete chloroplast genome of which is known as the 'asthma-plant' due to its medicinal use. The chloroplast genome of this species is 164,340 bp in length, including a pair of inverted repeat regions (IRs) (27,354 bp) that are divided by a large single-copy region (LSC) (91,373 bp) and a small single-copy region (SSC) (18,259 bp).

Equatorial Pacific forcing of western Amazonian precipitation during Heinrich Stadial 1.

Abundant hydroclimatic evidence from western Amazonia and the adjacent Andes documents wet conditions during Heinrich Stadial 1 (HS1, 18-15 ka), a cold period in the high latitudes of the North Atlantic. This precipitation anomaly was attributed to a strengthening of the South American summer monsoon due to a change in the Atlantic interhemispheric sea surface temperature (SST) gradient. However, the physical viability of this mechanism has never been rigorously tested.
