Soil deterioration due to long-term grazing of desert-steppe promotes stress-tolerant ecological strategies in plants.

Predicting the impact of grazing on desert steppes' vegetation is crucial for sustainable management. The competitor, stress-tolerator and ruderal (CSR) theory has offer valuable insights into plant adaptive capacity and predicting changes in vegetation structure. However, whether adaptive strategy of desert steppe change with grazing intensity is not understood yet.

Laponite-activated AIE supramolecular assembly with modulating multicolor luminescence for logic digital encryption and perfluorinated pollutant detection.

Recently, the non-covalently activated supramolecular scaffold method has become a prominent research area in the field of intelligent materials. Here, the inorganic clay (LP) promoted the AIE properties of 4,4',4″,4‴-(ethene-1,1,2,2-tetrayltetrakis(benzene-4,1-diyl))tetrakis(1-ethylpyridin-1-ium) (P-TPE), showing an astonishing 42-fold enhancement of the emission intensity of the yellow-green luminescence and a 34-fold increase of the quantum yield via organic-inorganic supramolecular strategy as well as the efficient light-harvesting properties (energy transfer efficiency up to 33 %) after doping with the dye receptor Rhodamine B. Furthermore, the full-color spectral regulation, including white light, was achieved by adjusting the ratio of the donor to the acceptor component and co-assembling with the carbon dots (CD).

Transition and regulation mechanism of bacterial biota in Kishu saba-narezushi (mackerel narezushi) during its fermentation step.

The transition of the bacterial biota of Kishu saba-narezushi (mackerel-narezushi) in the Hidaka region of Wakayama prefecture, Japan, was analyzed using amplicon sequencing based on the V3-V4 variable region of the 16S rRNA gene. In the non-fermented sample (0 day), the major genus with the highest abundance ratio was Staphylococcus. In the early stage (fermentation for 2 days), however, the genus Lactococcus became a dominant species, and in the later stage (fermentation for 5 days), the abundance ratio of the genus Lactobacillus increased significantly.

Evaluation of optional fee structures for solid waste management in China.

A municipal solid waste fee has become an important means for the implementation of the waste management rendered by the government all around the world. Based on the ecological environmental compensation theory, this article constructs an analytical framework of waste charging from the perspective of public policy evaluation, to carry on the comprehensive comparison and analysis to the operability, feasibility, validity, rationality, and universality of the two modes of waste charging: Ration charge and unit-pricing modes. The results indicate that in the cities with large amounts of waste production, long time of waste charging, and high disposal rate, pilot projects should be carried out; and the government needs to improve the construction of associated laws and regulations.

Municipal household solid waste fee based on an increasing block pricing model in Beijing, China.

This article aims to design an increasing block pricing model to estimate the waste fee with the consideration of the goals and principles of municipal household solid waste pricing. The increasing block pricing model is based on the main consideration of the per capita disposable income of urban residents, household consumption expenditure, production rate of waste disposal industry, and inflation rate. The empirical analysis is based on survey data of 5000 households in Beijing, China.
