Rickettsia japonica and Novel Rickettsia Species in Ticks, China.

PCR amplification indicated the minimum infection rate of Rickettsia spp. was 0.66% in Haemaphysalis longicornis ticks collected from Shandong Province, China. Phylogenetic analysis based on the rrs, gltA, ompA, and ompB genes indicated that the ticks carried R. japonica, Candidatus Rickettsia longicornii, and a novel Rickettsia species related to R. canadensis.

Updated Hourly Emissions Factors for Chinese Power Plants Showing the Impact of Widespread Ultralow Emissions Technology Deployment.

Nationwide severe air pollution has prompted China to mandate the adoption of ultralow emissions (ULE) control technologies at all of its coal-fired power plants by 2020. This process has accelerated greatly since 2014 and, combined with operational adjustments related to overcapacity, has reduced the emissions of nitrogen oxides (NO x), sulfur dioxide (SO2), and particulate matter (PM). Yet the quantitative understanding of ULE benefits is poor. Using detailed emissions data from 38 units at 17 power plants, corresponding to 10 combinations of ULE technologies representative of the Chinese power sector, we show that emissions factors for NO x, SO2, and PM are up to 1-2 orders of magnitude lower after ULE retrofitting. The effectiveness in cutting emissions shows a large spread across the various ULE technology combinations, providing an opportunity to choose the most efficient, economically viable technology (or a combination of technologies) in the future. The temporal variations in emissions at hourly resolution reveal the effects of power plant load on emissions, an increasingly important factor given that power plants are not operated at full capacity. These data will be useful in efforts to understand the evolving state of air quality in China and can also provide a basis for benchmarking state-of-the-art air pollution control equipment globally.

Exceptional and long-time economic development: CO2 emission reduction and adoption of green marketing in China.

This study aims to boost green bond China's adoption of green marketing; the current research focuses on green defaults as demand-side strategies. This paper panel data collected from 2002 to 2021 used econometric methods. Purposive sampling was used to collect information from respondents. The empirical findings show that the link between income and Green Business Initiatives (GBI) increases emissions of carbon dioxide. Moreover, trade openness raises carbon dioxide emission, but human capital reduces them. This article also makes some predictions about how monetary policies will affect the economy. A policy of open market operations in which the government discounts less for second-hand debt, lowering the market value of money, credit, and interest rates. Results (2) show that the descriptive statistics for the dependent and independent variables of the global market's first-layer model. Green bonds are priced 0.12% more in ask yield than its conventional counterparts on average. The 0.09% point mean of GBI demonstrates that the bid-ask yields of green bonds are somewhat lower on average than those of conventional bonds. The econometric findings of robustness checks reveal that GDP volatility is low and growth rates are higher in economies with GB marketing. Excellent and long-term financial development, as well as strong gross fixed capital formation, are hallmarks China region, which indicate higher levels of economic investment than their control counterparts.

Anaplasma species detected in Haemaphysalis longicornis tick from China.

Anaplasma are tick-borne obligatory intracellular bacteria, which infect humans and other animals. The Anaplasma species carried by ticks in China are not well studied. We collected 3145 questing Haemaphysalis longicornis ticks including 120 larvae, 2460 nymphs and 565 adults from vegetation in Jiaonan County, Shandong Province, China from 2013 to 2015. All ticks were examined for the presence of Anaplasma species by nested PCR amplification of the 16S rRNA gene. For further differentiation of A. capra from A. centrale, gltA and msp2 genes were sequenced for A. capra. Three Anaplasma species were detected in the nymph and/or adult ticks with the minimum infection rate of ticks as follows: 1.55% for A. bovis, 0.10% for A. phagocytophilum, and 0.03% for A. capra. These results indicated that the H. longicornis tick in Jiaonan County carried multiple Anaplasma species, which may be a challenge for public health in the studying area.
