Summary: This study demonstrates the efficiency of solarization-ozonation techniques for the removal of pesticides in soil. The combination of solarization and ozonation treatment was found to be effective for all the studied pesticides in both fresh and aged contaminated soils. However, the removal efficiency was lower for aged contaminated soils due to increased adsorption of pesticides. A pilot trial in a commercial farm soil showed a significant degradation of pesticides after 40 days of treatment. The results suggest that this combination of techniques holds promise for pesticide degradation in soil.

Summary: The study found that ozonation led to a dose-dependent increase in biological activity, particularly for substances that are recalcitrant to biodegradation. Additionally, ozonation enhanced the degradation potential of COD and BDOC, while also partially mineralizing organic compounds. These results suggest that a combination of ozonation and biological post-treatment can contribute to sustainable water resource management by reducing biodegradable organic carbon emissions.

Summary: The study prepared BC/lignin nanoparticles (LNPs) composite films with retarded biodegradability, which could expand their application area. The involvement of LNPs had limited influence on the productivity of BC but significantly delayed the biodegradation of composite films. The potential inhibition mechanism was identified as physical barrier and non-productive binding of LNPs.

Summary: Given that tree extracts such as tannin and lignin can be efficiently used as modifying materials, a bio-based biodegradable composite film (TLP) incorporating tannin and lignin as additives, together with polyvinyl alcohol (PVOH) as a matrix, was prepared. The film displayed a smooth surface without pores or cracks, and the addition of tannin and lignin improved its tensile strength. This enhancement was attributed to the weakening of hydrogen bonding in the PVOH film due to the chemical interactions between tannin, lignin, and PVOH. Furthermore, the TLP film exhibited good resistance against UV and visible light and showed biodegradability when contaminated with Penicillium sp.

Summary: This study analyzed the effect of lignin side chain spatial configuration on cooking performance and compared the structural characteristics of eucalyptus and acacia during cooking using ozonation, GC-MS, NBO, and 2D NMR techniques. The changes in lignin content during the cooking process were studied for four different raw materials using ball milling and UV spectrum analysis. The results showed a continuous decrease in lignin content during cooking, with stability reached only in the late cooking stage. The E/T and S/G ratios of residual lignin followed a similar trend. Different raw materials exhibited variations in cooking efficiency and transformation rules during the cooking process, suggesting the potential for improving pulping efficiency through different technological means.

Summary: The main purpose of this work is to develop an output state-dependent controller that solves the path-tracking deviation error for a skid-steering autonomous vehicle. The controller takes advantage of a nonlinear diffeomorphism that transforms the skid-steering autonomous vehicle into a multi-input multi-output chain of integrators. Through the step-by-step differentiator, the velocity and acceleration of the vehicle are estimated, which are then used in the controller implementation. The adaptive control design based on the estimated states enforces the convergence of the tracking trajectories for the vehicle to the origin.

Summary: This paper presents a novel adaptive control method for tracking bioinspired reference trajectories in the context of an exoskeleton robot. The proposed controller adjusts the gains of a state feedback structure using a controlled Lyapunov function and a robust exact differentiator. Simulations demonstrate the controller's efficiency in rejecting external disturbances and uncertainties, as well as achieving a significant power reduction compared to a non-adaptive controller. Experimental evaluation confirms the benefits of the proposed adaptive gain controller in successfully tracking biomechanically inspired reference trajectories, suggesting its potential for rehabilitation purposes.

Summary: The primary objective of this research is to determine if the dynamic version of an averaged sub-gradient (ASG) integral sliding mode (ISM) controller can effectively handle the end-effector acceleration tracking problem for a two-link robotic arm avoiding singularity conditions. The proposed scheme solves a nonlinear extremum seeking problem that minimizes a non-strictly convex function and allows for the achievement of the necessary ISM regime in the presence of considerable errors in the mathematical model description. A special switch between modes allows the controller to track accelerations even in extreme positions effectively.

Summary: This paper presents an adaptive controller with Barrier Lyapunov Functions (BLF) for a magnetic pendulum with state restrictions. The controller utilizes fixed electromagnets to induce motion on the pendulum and approximate functions to estimate the force between magnetic elements. The effects of state restrictions on the control action are considered based on a control BLF. Simulation and experimental results demonstrate the advantages of employing BLF controllers in mechanical systems with specific boundaries.

Summary: This study aims to design a robust nonparametric identifier for singular perturbed systems (SPSs) with uncertain mathematical models. The identifier uses a novel differential neural network (DNN) structure, which takes into account the multirate nature of SPS. A rational form of the DNN and a mixed learning law are proposed to solve the identification of the fast dynamics in SPS. The study also proposes a control Lyapunov function and a nonlinear parameter identification methodology for the design of the learning laws. A complementary matrix inequality-based optimization method is used to obtain the smallest attainable convergence invariant region. A numerical example of an enzymatic-substrate-inhibitor system is provided to demonstrate the application of the DNN identifier. The benefits of using the rational form for the identifier in terms of mean square error (MSE) are highlighted in the comparison with a classical identifier.

The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.
