Summary: The settlement of highway embankments has a direct impact on the structural safety of road pavement, making comprehensive assessment of their long-term settlement characteristics important in highway safety management. This study conducted long-term settlement monitoring on an embankment of the Xi'an-Xianyang Highway in Shaanxi Province, China, which was constructed using recycled construction and demolition waste. The results revealed different settlement characteristics and proposed control standards for sectional settlement of embankments constructed in this manner, while also establishing a model to predict long-term settlement using a Weibull distribution probability density function.

Summary: This paper presents a novel numerical approach to predict the irregular evolution of railway tracks. The model combines empirical settlement laws with finite element theory to consider train-track interaction and track-soil material behavior. The model is validated and used to demonstrate the importance of frequent geometry updates in accurate predictions. Additionally, a parametric study shows the effect of track subgrade material properties on track settlement.

Summary: In the early 1960s, four full-scale trial embankments were constructed in Norway to find low-cost solutions for roads on peatlands. These embankments, constructed using locally sourced sand and sawdust, have remained in perfect condition for 60 years. The study characterized the peat properties at the two sites and found them to be consistent with local and international experience. Short-term settlement was controlled by applied load, while long-term settlement was governed by peat consolidation properties. Pore water pressure dissipated quickly and modeling using the Soft Soil Creep model captured settlement and pore pressure dissipation well.

Summary: This study found that the application of biosolids did not significantly impact soil physical and nutrient health indices, but had an effect on chemical and biological indices. Overall soil health was optimized at a biosolids application rate of around 10 Mg ha(-1), as determined by combining all indices and considering past plant community research. The use of soil health tools can aid in determining the optimal organic amendment application rate for overgrazed rangelands.

Summary: This study investigates the residual settlement of roads on peat grounds by using the Finite Element Method (FEM) and incorporating a time-dependent model for peats. The study confirms the importance of the stress-dependency of the coefficient of consolidation and the viscosity-induced secondary consolidation in the residual settlement of peat grounds. The study also demonstrates that the viscoplastic parameters determined from standard oedometer tests can successfully reproduce the observed long-term settlement in peat-dominated sections of roads.

Summary: The study found that annual applications of alkaline stabilized biosolid (ATB) had a greater impact on bacterial community structure compared to fungi and eukaryotes. Higher rates of annual ATB applications resulted in lower bacterial alpha-diversity, as well as fungal and eukaryotic Shannon diversity, while single or lower rates of ATB annually showed increased alpha-diversity relative to the control.

Summary: Both quantifiable and semi-quantifiable poly-and perfluoroalkyl substances (PFAS) were evaluated in the influent, effluent, and biosolids of 38 wastewater treatment plants. PFAS were detected in all streams at all facilities. Evaluation of semi-quantified PFAS showed the presence of several classes of precursors in the influent, effluent, and biosolids. Analysis of mass flows showed that the majority of PFAS exited WWTPs through the aqueous effluent compared to the biosolids stream. Overall, these results highlight the importance of semi-quantified PFAS precursors in WWTPs, and the need to further understand the impacts of their ultimate fate in the environment.

Summary: Although the utilization of biosolids in agricultural lands is considered effective in improving resource reuse, the presence of antibiotic resistance genes (ARGs) limits its application. A 12-year experiment found that biosolids application significantly increased the abundance of ARGs in soil, and the increase was positively correlated with the dose of biosolids applied. Several subtypes of ARGs were detected, with mobile genetic elements (MGEs), aminoglycoside, and multidrug resistance genes being the most dominant types. Controlling the rate of biosolid application is crucial in reducing the accumulation and transfer of ARGs in soils.

Summary: The performance of a new battered driven minipile group system under uplift loading in a noncohesive material was investigated through field testing and physical and 3D numerical modeling. The study found that a group of minipiles can carry higher loads compared to single minipiles, and the configuration of the minipiles significantly impacts the uplift capacity. Among different configurations examined, diagonally installed minipiles engage a larger volume of soil with minimal negative group effect, achieving a higher uplift capacity.

Summary: This study examines the economic and environmental effects of transitioning towards more circular food systems in the European Union (EU27) by feeding animals with low-opportunity-cost feed and better utilizing local feed resources. The results show that providing subsidies for circularity and promoting the use of low-cost feed can increase animal production, but also have negative impacts on land use and emissions. On the other hand, promoting domestic feed sourcing through import tariffs can decrease animal production and greenhouse gas emissions in agriculture. However, complementary policies are needed to mitigate drawbacks and enhance benefits of a more circular agri-food system.
