Summary: Gully pots are widely used in urban catchments to control surface runoff and reduce sediment-induced blockages. However, the maintenance strategies for gully pots lack an evidence-based approach and clear objectives. This study investigated the factors influencing long-term sediment accumulation in gully pots. The results showed that seasonal activities and traffic conditions had impacts on sediment accumulation rates, and the configuration and size of gully pots also played a role. The commonly adopted maintenance frequency needs to consider the specific activities in the catchment.

Summary: The accumulation of microplastics on macrophytes plays a crucial role in their fate in the environment. Filamentous algae retain a significantly higher number of microplastics compared to non-filamentous algae when considering biomass as the unit. However, there is no significant difference in microplastic abundance between algal morphologies when using other units. Sediment collected under vegetated areas contains significantly higher microplastic concentrations, with filamentous algae retaining higher abundances of microplastics compared to non-filamentous algae.

Summary: The study reveals that mangroves impacted by anthropogenic activities in South America and Asia may have nitrogen and phosphorous accumulation rates up to seventeen times higher than those under conserved conditions, while in Oceania, these differences can be up to fivefold higher in impacted ecosystems compared to the conserved ones.

Summary: This study investigated the occurrence and seasonal variation of microplastics in the sediments of Liangfeng River in China. Results showed higher abundance of microplastics in sediments during the dry season compared to the rainy season, with polyethylene being the most abundant polymer. Small-sized microplastics can potentially migrate and redistribute via resuspension at different temporal and spatial scales.

Summary: This study shows that riverbed sediments in Japanese rivers undergo downstream fining, with grain size and thickness decreasing towards the river mouth. The maximum grain size and thickness are linearly correlated with maximum water discharge, distance from the edge of the continental shelf, and the river gradient during the last glacial period. These findings suggest that the production of coarse materials was not solely due to periglacial processes, but occurred in a limited area of the Japanese Islands during the last glacial period.

Summary: This paper introduces a modified drafting system, called the soft drafting system, based on the ring spinning frame. By comparing the pressure distributions and apron slippages of the soft drafting system with the conventional drafting system, this study shows that the soft drafting system has a smaller floating area, a longer and more stable friction zone, and a curved channel that helps reduce yarn imperfections. The soft drafting system also solves the problem of apron-to-apron slippage in the conventional drafting system, resulting in improved yarn quality stability and drafting efficiency.

Summary: The investigation on EL-C01 sediment core provides new information on sedimentary regime and anthropogenic impacts in the Po river prodelta area during the last 175 years. The results show an increase in trace metals concentrations after major flood events of the Po river in the 20th century, and a decrease of heavy metal contents from the second half of the 1980s, possibly due to environmental policies.

Summary: This study revealed the characteristics of bacterial communities on road deposited sediments (RDS) in urban and suburban areas through seasonal and daily scales. It was found that the season showed a higher association with bacterial community diversity than land use and particle size in urban areas. The short-term study period showed a substantial increase in bacterial community diversity, with the dominant bacteria variation in suburbs being fit by a quadratic function.

Summary: The Late Devonian Besa River Formation in northeastern British Columbia, Canada, is an organic-rich shale sequence with significant natural gas reserves. High-resolution elemental geochemistry of the formation revealed that Unit III had the highest total organic carbon content due to low clastic influx and euxinic bottom conditions. Sea level changes, productivity, and organic matter influx also played important roles in organic matter accumulation in the shale.

Summary: The mechanism of seasonal persistence barrier (SPB) is primarily influenced by the declining growth rate or increasing noise forcing, rather than the minimum or maximum of growth rates or noise. In weakly damped systems, the phase of SPB is delayed by approximately one season from the declining signal-to-noise ratio (SNR). This mechanism provides insights into understanding the observed variability of sea surface temperatures in the tropical and North Pacific regions.

Summary: In recent years, WEDM has become an important alternative machining method in precision machining due to its greater flexibility and lower wear cost compared to traditional machining. However, wire breakage during WEDM is a significant problem that affects machining quality and efficiency. This work focuses on investigating the causes of wire breakage, using observation, simulation, and experiments. The findings provide a better understanding of the impact of discharge accumulation on wire breakage.

Summary: A new dust mitigation technique for photovoltaic panels has been developed, which combines a wind shield, antistatic hydrophilic coating, and a mechanical vibrator. The experimental results show that this technique can effectively reduce the negative impact of dust accumulation on panel efficiency, particularly in winter.

Summary: The Las Vegas Formation is a well-characterized sequence of groundwater discharge deposits in southern Nevada, with a significant aeolian component. The sediments are dominated by carbonate minerals but also contain silicate minerals, and around 25% of the deposits were introduced by aeolian processes. These results have broad implications for investigations of GWD deposits in the southwestern U.S. and worldwide.

Summary: The study aims to investigate the influence of seasonal changes on the pollution loads of the sediment in a coastal area by analyzing the nutrients, organic carbon, and particle size of sediment samples collected from different sampling stations in three different seasons. It also examines the impact of anthropogenic and natural activities on the sediment quality of the coastal area. The results show significant differences in sediment quality among seasons, indicating contamination from both natural and man-made sources. This study will contribute to the development of effective management strategies for the protection and restoration of degraded coastal ecosystems.

Summary: The terra rossa on the Cayman Islands is mainly sourced from wind-blown volcanic dust or Saharan dust, with a strong affinity to Saharan dust blown into the Caribbean region each year. The low SiO2/Al2O3 ratios of the Cayman terra rossa is attributed to the rarity of quartz. The formation of the terra rossa on the Cayman Islands has likely been an ongoing process for at least the last 5 million years.

Summary: Miocene carbonate successions on Shidao Island in the Xisha Islands, South China Sea, include formations formed of limestones and dolostones, with several intervals of unconformity-capped dolostones. The dolomitization process mainly occurred in strata with high porosities and permeabilities, suggesting that dolomitization was not limited to near-sea-level strata. The exact properties of the seawater that promoted dolomitization are still uncertain.
