Our measurements show that the post-retrofit skyglow became brighter and extended higher in the sky, but upward radiance, as measured by the day-night band radiometer, decreased. These divergent results are likely explained by a substantial increase in light emitted at wavelengths shorter than 500 nm, and a relative decrease in upward light emission due to better shielded luminaires. These results also demonstrate that earlier models relating VIIRS day-night band data to skyglow will - at a minimum - require substantial revision to account for the different characteristics of solid state luminaires.According to data from the working reports of China's 244 prefecture-level city governments from 2004 to 2016, we used the instrumental variable method to identify the effects of governments' behavior of setting economic growth targets on regional green technology innovation. The results show that the setting and top-down amplification of economic growth targets have significant inhibitory effects on green technology innovation. The inhibitory effect is more prominent in cities with rapid economic growth and over fulfilment of economic growth targets. In addition, the higher the degree of over fulfilment of the economic target becomes, the more prominent the inhibiting effect is. An impact mechanism analysis reveals that economic growth target constraints affect regional green technology innovation through an industrial structure effect and foreign investment introduction effect.In the present study, a two-step bioaugmentation strategy (TSBS) was implemented by using indigenous bacterial consortium to enhance the degradation of total petroleum hydrocarbons (TPH) from petroleum refinery sludge (PRS). A bacterial consortium was developed using four indigenous isolated strains, Dietzia sp. IRB191, Dietzia sp. IRB192, Staphylococcus sp. BSM19 and Stenotrophomonas sp. IRB19 from PRS. The optimum conditions of pH, temperature, and sludge concentration were 7, 34 °C, and 2% (w/v), respectively, for maximum TPH degradation, obtained using one variable at a time approach. Under the optimal culture conditions, the developed consortium was inoculated twice to the culturing medium, at the beginning (0th day) and again on the 10th day for implementing a novel TSBS. The maximum TPH degradation of 91.5 ± 2.28% was found with TSBS, which was 1.18 times higher than that of SSBS (77.3 ± 2.6%) in 15 days of incubation. GC-FID study also confirmed that the TPH present in the PRS was effectively degraded by the bacterial consortium with TSBS. The TPH degradation by using TSBS proceeded according to the first-order kinetics with a rate constant of 0.155 d-1. Hence, biodegradation using a TSBS can be considered an effective and eco-friendly process for safe disposal of petroleum refinery sludge.To better analyze China's carbon neutrality target, this study investigates the effect of green innovation and investment in the energy industry on China's provincial and regional data from 1995 to 2017. Using Westerlund and Edgerton's panel cointegration test, the authors found a stable long-run relationship between CO2 emissions and its determinants. We found that under major structural breaks at the local, regional, and global levels, such as the East Asian crises of 1997, the financial crises of 2007-2008, China's RMB exchange rate reform announced on August 11, 2015, and mild recession in 2001, CO2 emissions, income, green innovation, renewable energy use, and energy industry investment are cointegrated. The environmental Kuznets curve hypothesis is valid. In the long run, income, environmental innovation, investment in the energy industry, and renewable energy consumption are key contributors in explaining CO2 emissions. The empirical evidence from augmented mean group (AMG) is consistent with the estimates of CS-ARDL. Concerning practical implications, the findings suggest that there is a need to switch the Chinese economy to more sustainable sources of energy, a viable solution to abate environmental degradation. China should introduce and shift investments to green innovation.Outdoor recreation decision-making has received significant research interest over the last fifty years. In the context of campsite choice, this previous research has almost exclusively used stated preference data and aspatial methods to understand decision-making. This present research seeks to understand how recreationists reach decisions on the selection of campsites and what aspects of the recreational setting drive demand through an examination of a big dataset of revealed preference data using a spatial regression. Specifically, we examine which managerial, social, and ecological aspects of the setting influence demand for campsites in Zion National Park's (USA) Watchman Campground using reservation data from the Recreation Information Database (RIDB). Results indicate that price, access to electricity, ease of access, and proximity to the Virgin River are significantly predictive of demand. Study implications for park management, including campsite allocation and distributive justice, are provided. https://www.selleckchem.com/products/kd025-(slx-2119).html Additionally, implications for future research methodology, including the use of transaction-style big data in protected area management research, are discussed.Ag3PO4 is an indirect bandgap semiconductor with excellent photocatalytic activity. However, it has not been widely used so far for the treatment of polluted wastewaters. This scarce use in wastewater treatment can be mainly attributed to its large crystallite size, which would be due to rapid agglomeration during the synthesis process, as well as to the photo-corrosion problem affecting this material. Hence, it would be crucial to develop a photocatalytic system involving Ag3PO4 nanoparticles with enhanced properties, such as higher specific surface area and excellent photocatalytic stability. To meet this demand, a novel Ag3PO4/boron carbon nitrogen (Ag3PO4/BCN) composite photocatalyst was successfully prepared in the present study via electrostatically driven self-assembly and ion exchange processes. After characterization and assessment, it was shown that the as-prepared Ag3PO4/BCN nanocomposite photocatalyst not only contains smaller Ag3PO4 nanoparticles, but also exhibits an enhanced visible-light photocatalytic activity for Rhodamine B (RhB) Methyl Orange (MO) and Tetracycline (TC) and improved stability, without decrease after 5 cycles, compared with pure Ag3PO4 nanoparticles.
