Summary: This study investigated the soil organic carbon (SOC) stocks in seasonally frozen ground (SFG) in the Tibet Autonomous Region, China, in 2020 and 2021, and explored the effects of various factors on SOC using partial least squares structural equation modeling (PLS-SEM). The results showed that C inputs exerted the greatest control on SOC, and the influence of these factors decreased with increasing soil depth. Additionally, timely spatial SOC estimates were found to be important for assessing carbon stocks in the context of environmental changes.

Summary: This study compares weathering profiles developed on granite and basalt rocks under different climatic conditions in India. The results show the significance of climate conditions and lithology in controlling weathering advancement. The distribution of major oxides and trace elements is influenced by weathering intensity and formation of secondary minerals. The principal component analysis reveals three components that account for a significant portion of the variance, related to weathering intensity, lithology, and location-specific factors.

Summary: This study tested different methods for generating accurate SOCD maps in the Yangtze River Delta, using soil samples and published literature. Artificial neural network (ANN) and multiscale geographically weighted regression (MGWR) performed well in capturing the spatial pattern and accuracy measures, respectively. Fusion models improved the accuracy compared to individual methods, with the MGNW_F model performing the best. Additional soil samples and method fusion have the potential to enhance the accuracy of SOCD mapping.

Summary: This study investigated the distribution of rare earth elements (REEs) in soils at different elevations in the Central Mountain Range of Taiwan and its relationship with climatic changes. The results showed that REE content decreased with increasing elevation and rainfall. Clay content was correlated with REEs, with heavy REEs preferentially sequestered by the soil. These findings suggest a relationship between soil development and REE fractionation.

Summary: In the past decade, accurate, sustainable, and effective planning of torrent control structures has become essential to reduce hydro-geomorphic risk. High-Resolution Topography data greatly simplifies the monitoring of sediment morphology dynamics and the understanding of the interaction with torrent control structures. Combining field surveys can provide valuable information for watershed management plans.

Summary: This study introduces the priority-flood flow direction algorithm to improve the generation of slope units and compares them to slope units based on the subbasin division method in landslide susceptibility maps (LSMs). The results show that the improved slope units perform better at large scales, reducing striped distributions and optimizing patterns in the LSMs. Therefore, the PFD algorithm is valuable for large-scale research.

Summary: Landscape appearance in the European Alps is influenced by various environmental and human-induced factors. Significant landscape change has occurred in all regions, affecting biodiversity and ecosystem services. Factors such as decrease in agricultural land and forest expansion play important roles. Regional framework conditions are more important than national frameworks, and higher green subsidies can have both positive and negative impacts on landscape diversity and ecosystem services.

Summary: This study investigates the effects of inorganic draw solutes on membrane fouling and reverse diffusion in forward osmosis systems. It is found that the formation of a membrane fouling layer can influence the reverse diffusion of ions, leading to exacerbation of membrane fouling in certain cases. Furthermore, different draw solutes have different impacts on membrane fouling.

Summary: This study demonstrates that negative pressure mode can enhance the operational stability in membrane distillation, especially for low surface tension organic solvents. However, it is less effective for surfactant solutions. The study also reveals the different mechanisms of membrane wetting and fouling for ethanol and Tween20 solutions, and shows that maintaining a large contact angle can prevent membrane wetting in ethanol solutions.

Summary: Fisheries management is transitioning from a single-species approach to an ecosystem-based approach to address the complexities of mixed-species fisheries. A dual compartment codend concept can provide a complex selectivity profile and allow for flexible adjustments at sea, improving compliance with management objectives.

Summary: Several studies on COVID-19 have found that the virus can be detected in raw sewage, posing potential health risks for wastewater treatment workers. This study gathered data on SARS-CoV-2 concentrations in wastewater and used a quantitative microbial risk assessment to estimate the daily probability of infection for workers. It was found that the risk decreased with higher temperatures and humidity levels. Direct ingestion of wastewater droplets was found to pose a higher risk than inhalation of bioaerosols. Measures such as implementing better ventilation and adding more work shifts can help reduce the risk of infection among workers.

Summary: Hydrodynamic processes play a crucial role in the transmission of sediments, microbial assembly, and organic carbon redistribution in the ocean. Through experiments and analysis, we found that hydrodynamics shape the assembly of microbial communities and control the redistribution of different sourced organic carbon, thereby influencing microbial-mediated biogeochemical transformation.

Summary: This study addresses the storage space allocation problem of container yards based on the dual-cycle operation mode. A mixed integer programming model is established to optimize container transportation distance. The results show that dual-cycle operation can decrease transportation distance and the space allocation method based on it is more effective than traditional methods. The study also provides management insights for container ports and suggests effective solutions for bottleneck problems.

Summary: Anaerobic and microalgae-based technologies have emerged as sustainable alternatives for municipal wastewater treatment. However, the presence of viruses in the treated wastewater is a major concern for reuse applications. This study assessed the ability of these technologies to reduce viruses during secondary wastewater treatment. The results showed that all technologies were effective in reducing the concentration of viruses, with microalgae-based treatment exhibiting the highest potential for reducing the disinfection requirements of treated wastewater.
