“…The agglomeration efficiency represents the proportion of water droplets that gather after a collision in the flow field. 49,53 Currently, there are primarily two prevailing models in the existing literature for quantifying the agglomeration efficiency of particles subsequent to collision: linear model and curve model. Among them, the linear model does not consider the van der Waals attraction between particles and the shear force of the flow field on the particles, and the model thinks that the particles will definitely aggregate once they collide, 54 therefore, the calculation is often greater than the actual value, and the accuracy is lacking.…”

“…Based on previous research, this study focuses on examining the microscopic evolution behavior of wax crystals and water droplets within waxy crude oil emulsions. Furthermore, through rheological experiments and microscopic observations, combined with population balance theory, 49 a mathematical model describing water droplets behavior under shear flow conditions was developed.…”

“…Each species is weighted according to the trophic level of its feed guild (usually assumed to be trophic level 1 for producer and detritus) and the proportion of its composition in the food. This concept of trophic level is also known as effective trophic level (ETL) (Leontief, 1965; Song, 2004), which can reflect the nutritional status of each FG in the ecosystem in more detail (Chen et al, 2008):

{normalETL}_{normalmodel} = \frac{\sum_{i = 1}^{N} false(B_{i} * {TL}_{i} false)}{\sum_{i = 1}^{N} B_{i}}

where

{ETL}_{model}

is the trophic level of each model, i is the number of FGs, N is the total number of FGs, and

{ETL}_{i}

is the trophic level of FGs.…”

The biological and ecological integrity of marine ecosystems in the Pearl River Estuary (PRE) has been compromised due to overfishing and water pollution. Fishing moratorium and artificial reef construction have been implemented in Wanshan and Miaowan for resource protection and restoration. Therefore, food web structure and trophic pathways of Wanshan, Miaowan, and Wailingding in different temporal and spatial situation will be determined using the Ecopath model, as well as the keystone species affecting these ecosystems, which can provide a basis for fishery management. The results showed that the energy transfer efficiency of IV and V trophic levels (TL) was higher than that of II and III‐TL before and after fishing moratorium, and the energy transfer efficiency of artificial reefs II and III‐TL was only slightly higher than that of nonartificial reefs in Wanshan. In addition, the mean values of ecosystem property indicators (consumption, respiration flow, total system throughput, and total biomass) after the fishing moratorium were significantly higher than those before the fishing moratorium. The average value of the ecosystem attribute indicators (consumption, respiration flow, total system throughput, and total biomass) of artificial reefs is lower than those of nonartificial reef areas, which may be related to the differences in community composition between artificial reefs and non‐artificial reefs. Finally, Nemipterus japonicus and Gastrophysus spadiceus are keystone species that distinguish the Wanshan and Miaowan artificial reefs from other areas. Overall, the fishing moratorium has a positive effect on the short‐term restoration of fishery resources, mainly restoring short‐life cycle organisms. However, the construction of artificial reefs will be more conducive to the persistence of ecosystem restoration. In addition, reasonable proliferation, release and fishing of N. japonicus and G. spadiceus will be beneficial to the sustainable utilization of fishery resources.

“…As important adults in the family and school environment, parents and teachers interact with each other to affect student development [54]. From the perspective of social support theory, social support is a selective behavior that people give material and spiritual help for free to disadvantaged groups in society [55]. Social supporters include people who can have a positive meaning for suffering individuals around them, such as family members, friends, relatives, teachers, etc.…”

Background: Studies show that cooperative environments enhance student performance. However, school bullying can significantly undermine peer cooperation. There is limited research on how school bullying impacts peer cooperation and the mechanisms involved. Methods: Using data from 15-year-old middle school students in four Chinese provinces and cities, as part of the 2018 Program for International Student Assessment (PISA), this study employs a moderated mediation model. It examines the negative effects of school bullying on peer cooperation, the mediating role of school belonging, and the moderating effects of teacher support and parents’ support. Results: School bullying negatively impacts peer cooperation. School belonging partially mediates this relationship. Teacher support moderates the effect of school bullying on school belonging, which in turn affects peer cooperation. Parents’ support moderates the direct impact of school bullying on peer cooperation. Conclusion: School bullying reduces peer cooperation by diminishing students’ sense of belonging in school. This effect is lessened with increased support from teachers and parents. The findings suggest that while social support is beneficial, it must be balanced and not excessive.
