Abstract

In this paper a new observer is introduced to estimate the Crystal Size Distribution (CSD) only from the measurements of the solute concentration, temperature and a model of the growth rate. No model of the nucleation rate is needed. This approach is based on the use of a Kazantzis-Kravaris/Luenberger observer which exponentially estimates functionals of the CSD. Then, the full state is estimated by means of a Tikhonov regularization procedure. Numerical simulations are provided. Our approach relies on an infinite-dimensional observer, contrarily to the usual moment based observers.

Abstract

Leptospirosis is a re‐emerging bacterial zoonotic disease that affects both humans and animals, with a significantly higher incidence in tropical and sub‐tropical regions. Disease control, epidemiology, and surveillance rely on a One Health approach, as accurate detection can be applied to humans, animals, and the environment. This study represents the first attempt to develop a method for detecting the pathogenic Leptospira santarosai serovar Shermani based on the latex agglutination reaction. The serological activity of the antibody is examined to achieve a high titer of antibody before adsorption onto polystyrene particles. Using a pH medium of 6.8–7.8, total antibody adsorption of up to 3 mg m−2 is achieved. Particle agglutination is observed after incubating the antibody‐adsorbed PS with leptospiral culture for 4 min, revealing a detection limit of 1.7 × 102 leptospires mL−1. Interestingly, the detection limit increased by 1000 times when observing agglutination using spectrophotometer. The test exhibits high specificity with Shermani and shows negligible cross‐agglutination with non‐pathogenic Leptospira and water‐borne bacteria. Agglutination testing in collected water samples from natural sources demonstrates a good correlation with culture technique. This simple and rapid leptospires agglutination detection method can be applied as a screening test in environmental, human, and animal specimens. [ABSTRACT FROM AUTHOR]

Abstract

Polyvinyl chloride (PVC) recycling is crucial for mitigating the environmental impact of PVC wastes, which take decades to decompose in landfills. This review examines the current state of PVC recycling processes, focusing on challenges and future research opportunities. It explores the types and sources of PVC wastes, including post‐consumer, industrial, and construction wastes. Conventional recycling methods such as mechanical, thermal, and chemical recycling are discussed, highlighting their advantages, limitations, and successful applications. Furthermore, recent advances in PVC recycling, including biological, plasma‐assisted, and solvent‐based recycling, are explored, considering their potential benefits and challenges. The review emphasizes the European context of PVC recycling, as the region has implemented regulatory initiatives and collaborations. It points out the Circular Economy Action Plan and directives targeting PVC waste management, which have promoted recycling and established a supportive framework. Challenges of current PVC recycling methods and technologies, such as low yield and high energy consumption, are identified. The review calls for the development of efficient and cost‐effective recycling technologies, along with improvements in recycling infrastructure and consumer awareness. Assessing the environmental and economic impacts, PVC recycling significantly reduces greenhouse gas emissions and conserves resources compared to virgin PVC production. The economic benefits include job creation and reduced raw material costs. [ABSTRACT FROM AUTHOR]

33. Monitoring and Modeling of Creaming in Oil-in-Water Emulsions

Abstract

This work combines experimental and modeling investigations to monitor the dynamics of creaming in oil-in-water emulsions. Turbidity and Raman spectroscopy methods were compared for the experimental monitoring of creaming of n-hexadecane droplets in water. A creaming model is developed based on the convection-diffusion equation. The model accounts for the full droplet size distribution. The experimental data were used to identify the diffusion coefficient of the oil droplets and the Richardson–Zaki coefficient correcting the effect of the local volume fraction. The droplets’ size and concentration are varied to evaluate their effect on the creaming rate. The developed model could accurately predict the kinetics of creaming in the different considered cases. It can be used for emulsion stability studies, for instance, in food/pharmaceutical industries and/or for gravity separator design and monitoring.
