Evaluation of advanced soil models for the cyclic soil-structure

-

 



The evaluation of advanced soil models for the cyclic soil-structure interaction (SSI) of integral bridges is crucial for improving the accuracy of structural performance assessments under repeated loading conditions. Integral bridges, which lack expansion joints, rely heavily on the interaction between the superstructure and the surrounding soil to absorb and redistribute stresses. During thermal expansion and contraction cycles, this interaction becomes highly nonlinear, making traditional modeling approaches inadequate. Advanced soil constitutive models—accounting for strain hardening, hysteresis, and soil degradation—offer a more realistic representation of cyclic behavior. By integrating these models into finite element analyses, researchers can predict bridge response more accurately, optimize design, and enhance long-term durability. This research supports resilient infrastructure by reducing maintenance costs and mitigating structural vulnerabilities related to soil behavior under cyclic loads.

From Waste to Growth Evaluating Leachate Sludge for Sustainable Plant Cultivation

-
  Transforming waste into a resource, leachate sludge—often a by-product of landfill operations—holds significant potential for sustainable plant cultivation. Rich in organic matter, nutrients, and beneficial microbes, it can enhance soil fertility, improve water retention, and reduce dependence on synthetic fertilizers. Proper treatment and monitoring are essential to minimize heavy metal toxicity, salinity, or pathogen risks, ensuring environmental safety and crop health. By integrating leachate sludge into circular agriculture practices, waste management facilities can contribute to greener landscapes, reduced landfill impacts, and increased agricultural productivity, fostering a closed-loop system that benefits both the environment and society. #FromWasteToGrowth #LeachateSludge #SustainableAgriculture #CircularEconomy #SoilFertility #WasteManagement #GreenFarming #OrganicMatter #SoilHealth #EcoFriendlyCultivation #LandfillByproduct #SustainablePlantGrowth #AgriculturalInnovat...

Sustainable iron recovery from tailings via green reduction technology: from waste to resource

-
  Sustainable iron recovery from tailings via green reduction technology represents a promising pathway to transform mining and metallurgical waste into valuable resources while minimizing environmental footprints. Tailings, often considered as hazardous by-products, contain significant quantities of iron that can be recovered through innovative eco-friendly reduction processes. Unlike conventional methods that rely on high energy input and carbon-intensive agents, green reduction technologies utilize renewable energy, biomass-derived reductants, or hydrogen-based approaches to extract iron efficiently. This strategy not only reduces greenhouse gas emissions but also mitigates the risks of soil and water contamination caused by tailings storage. By converting waste into a resource, the approach contributes to the circular economy, enhances raw material security, and promotes sustainable mining practices. Moreover, large-scale adoption of such technologies could help industries achi...

Early water-status indicators under combined metal toxicity and drought in tomato leaves

-
 Early water-status indicators in tomato leaves under combined metal toxicity and drought stress provide critical insights into plant physiological responses before visible damage occurs. Exposure to heavy metals such as cadmium or lead disrupts root water uptake and alters osmotic balance, while concurrent drought stress exacerbates water deficits by reducing stomatal conductance and leaf turgor. Monitoring parameters such as relative water content (RWC), leaf water potential, osmotic potential, and chlorophyll fluorescence can help detect early declines in plant hydration status. Additionally, changes in proline accumulation, electrolyte leakage, and leaf temperature (via thermal imaging) serve as sensitive markers of stress interaction effects. Understanding these early indicators enables timely interventions in tomato cultivation, helping mitigate yield losses and improve resilience in contaminated and water-limited environments. #TomatoStress #WaterStatusIndicators #MetalToxi...
