Tremella is native to China and can be used as both medicine and food. It is loved by people and is known as the crown of mushrooms. In this study, we used anthropomorphic techniques to unfold the story of this mushroom by examining “yellow and white” tremella. We describe the tremella’s appearance, environment, cultivation techniques, functions, applications, and its “companion” relationship with grey fungus. This study will aid in preventing counterfeiting of tremella to maintain a fair but competitive environment. We aim to expand the scientific knowledge of this mushroom, stimulating the scientific spirit and cultivating the professional ethics and social responsibility of students. [ABSTRACT FROM AUTHOR]

This study focuses on the technological origin of stamped hard pottery, one of the precursors to Chinese porcelain, developed in the Late Neolithic period of China. 160 ceramic sherds of stamped hard wares from the Nanshan site (5300–4300 cal. BP) and Yanzaidong site (5000–4300 cal. BP) were investigated through water absorption, Vickers hardness, petrography, ED-XRF, thermodilatometry, XRD, and SEM-EDS. The results indicate that two categories of samples exhibit commendable physical properties, comparable to stoneware, attributed to specific high-alumina clay with low fluxing elements (porcelain stone), fired at high temperatures ranging from 1100 to 1250 °C. The other categories of samples appear to be defective products during firing process, or have another raw material source, contributing to a diversity of pottery at the two sites. Nanshan and Yanzaidong unequivocally emerge as the earliest known production of stamped hard pottery, dating back to 5000 cal. BP, marking a revolutionary advancement in high-firing technology during the Late Neolithic China. • Earliest known stamped hard pottery (a precursor to porcelain) dating back to 5000BP • Late Neolithic China witnesses a high-firing revolution (firing to 1100–1270 °C). • Pioneering mass utilization of porcelain stone in pottery production. • Multidisciplinary analysis with a substantial sample size.

• By improving INNOV, EDEX and degree of openness, the interaction of labor quality and production technology can be better. • Provinces with a moderate CDD should make efforts to evaluate new technology and decide how much subsidies will be given. • Improving the degree of population concentration of the central and western provinces with very low CDD can increase CDD. Effective factor inputs and sustainable industrial development are essential for supply-side structural reforms, which are mainly based on the coordinated development of labor quality and production technology. This study explores the coordinated development of labor quality and production technology, using provincial data from China. The results show an interaction between labor quality and production technology. However, China's coordinated development of labor quality and production technology is low because of issues including its innovativeness, education expenditure, technology value, and the openness of the economy.

Indirect emission from household consumption, which is affected by technologies of production sectors, is the significant contributor to national CO emission. Input-output model is preferred when direct and indirect transactions and emissions are considered simultaneously. Based on input-output model, this study applies the sensitivity analysis to indirect emission from rural and urban domestic consumption, respectively. It allows us to investigate the influences of the technology change both at the transaction level and at the sector level. In addition, multi-years symmetrical input-output tables are adopted to obtain dynamic analysis in order to study the variation trend of the influences. At the transaction level, the technology change of production and supply of electric power and heat power self-supplied intermediate inputs exerts the most significant influence on indirect emission from both rural and urban consumption. At the sector level, indirect emissions from rural and urban consumption are both the most sensitive to the technology change of chemistry industry. Furthermore, there are more key transactions selected under consideration of rural domestic consumption compared with the urban. Additionally, the influencing degree and variation trends of the same technology change would be different between rural and urban situation. According to the above findings, policy recommendations aiming at achieving emission abatement from household consumption are provided in detail. [ABSTRACT FROM AUTHOR]

The increasingly serious agricultural pollution in China poses the question of whether the Chinese government can adopt environmental protection policies to achieve a "win-win" situation of promoting the progress of agricultural production technology and environmental regulation. This research adopts data envelopment analysis method to measure the progress index of production technology of 31 provinces in China to evaluate the effects of environmental regulations on the progress of agricultural production technology. Panel data method is also used to conduct an empirical test to explore the relationship of the intensity of agricultural environmental regulation, human capital, industrial structure, income level, and related technical factors with the progress of production technology. Results indicate that an increase in the intensity of environmental regulations causes first a decrease in the level of agricultural production technology in the central and eastern regions of China, which then gradually increases, thereby indicating a significant "U" curve trajectory and high statistical significance. By contrast, the western region did not form a statistically significant U-type relationship. In the process of promoting agricultural environmental protection policy, the Chinese government should devote more efforts to strengthening agricultural environmental protection and should attach greater importance to the methods and implementation of agricultural environmental regulations.

Laboratory based research on the physical properties of gas hydrate hosting sediment matrix was carried out on the non-pressurized hydrate-bearing sediment samples from the Chinese Guangzhou Marine Geological Survey 2 (GMGS2) drilling expedition in the Pearl River Mouth (PRM) basin. Measurements of index properties, surface characteristics, and thermal and mechanical properties were performed on ten sediment cores. The grains were very fine with a mean grain size ranging from 7 to 11 µm throughout all intervals, which provide guidance for the option of a screen system. Based on X-ray Computed Tomography (CT) and SEM images, bioclasts, which could promote hydrate formation, were not found in the PRM basin. However, the flaky clay might be conducive to hydrate formation in pore spaces. The measured sediment thermal conductivities are relatively low compared to those measured at other mines, ranging from 1.3 to 1.45 W/(m.K). This suggests that thermal stimulation may not be a good option for gas production from hydrate-bearing sediments in the PRM basin, and depressurization could exacerbate the problems of gas hydrate reformation and/or ice generation. Therefore, the heat transfer problem needs to be considered when exploiting the natural gas hydrate resource within these areas. In addition, the results of testing the mechanical property indicate the stability of hydrate-bearing sediments decreases with hydrate dissociation, suggesting that a holistic approach should be considered when establishing a drilling platform. Both the heat-transfer characteristic and mechanical property provide the foundation for the establishment of a safe and efficient production technology for utilizing the hydrate resource.
