Soil stabilisation is commonly used to reduce this risk, especially for light, shallow constructions. In Benin, palm branches are often discarded, polluting the environment. This study examines the impact of palm fibers on the geo-mechanical properties of the soil in Igana commune in Pobè. Physical and mechanical tests were carried out. The physical tests classify this soil as A-7-5 according to the HRB classification: a clayey soil, of the very plastic, non-organic, non-inactive silt type, with a high swelling potential and a high plasticity index. The mechanical tests revealed that adding 0.30% fiber increased the compressive strength at 7 days, reaching 0.025 MPa, confirmed by the flexural test with the same fibre content. As for the other mechanical tests, we obtained a maximum value of 1.63 for 95% raw clay in the CBR test and a maximum cohesion at 0.15% palm fiber in the shear test.<#LINE#>Agbelele, K. J., AÏSSE, G.

The GIXRD pattern of the as-prepared PMMA/Fe nanocomposite film showed the presence of Fe in metallic state with BCC phase in the nanocomposite. The MOKE magnetometer record reveals the ferromagnetic nature of such nanocomposite. AFM study shows evenly dispersed Fe nanoparticles. The UV-VIS spectroscopic studies showed that on incorporation of Fe nanoparticles, the % transmission decreased drastically, band gap got reduced but the refractive index, dielectric constant and optical conductivity increased.

They are expansion devices that use the kinetic energy of a primary flow for the compression of a secondary flow. Their performance remains low, which still makes their wide market penetration difficult compared to more conventional systems. Aligning with the above-mentioned objectives, the present work addresses the evaluation of five recognized turbulence models to study supersonic ejectors on a refrigeration system operating with R134a refrigerant. Validation focused on shock position, shock force with mean pressure recovery projection. The study focused on the influence of operating conditions, primary nozzle outlet position and wall roughness degree on the performance of a supersonic ejector. The Navier-Stokes equations for a two-dimensional, axisymmetric and stationary flow were discretized by the finite volume method under the ANSYS environment with a joint use of data from the REFPROP 7.0 database (REF rigerants PROP erties). The simulation of four two-equation turbulence models (standard k-ε, k-ε RNG, k-ε feasible and standard k-ω), as well as a four-equation model (SST transition), in their version for high Reynolds number is carried out. The numerical model is in good agreement with the experimental pressure profiles. The results presented concern in particular the structure of the mixing layer and the transient character of the shock wave position in the ejector. The results reveal that all models predict a good entrainment ratio. The standard k-ω model gives a better accuracy. It anticipates the onset of the shock at x=0m. The shock of the other models appears afterwards but always in the mixing chamber (between 0 and 0.04m).<#LINE#>Victorin, C. K., Louis, A. O., Alain, A., & Clotilde, G. T.

This paper presents an in-depth analysis of VGG-19, focusing on its architecture, role in face recognition, and integration with other techniques to improve accuracy. The study employs two prominent datasets, Labeled Faces in the Wild (LFW) and CelebA, to evaluate the model's performance. Key steps include data preprocessing, transfer learning, and fine-tuning of the VGG-19 model, followed by an assessment using metrics such as accuracy, precision, recall, F1-score, and ROC-AUC. The experimental results demonstrate the model's robustness and efficiency, with high accuracy and minimal misclassifications across varying conditions. Challenges encountered, such as high computational requirements and handling occlusions, are addressed through techniques like model pruning and data augmentation. Future work will explore hybrid models and optimization for real-time applications.<#LINE#>Sun, Y., Chen, Y., Wang, X., & Tang, X.

Traditional management practices, including the use of antibiotics and chemical treatments, have proven insufficient and often detrimental to both shrimp health and the environment. This study explores the potential of probiotics as a sustainable alternative for enhancing shrimp immunity and managing WSSV outbreaks. Probiotics are beneficial live microorganisms that provide health advantages to the host when consumed in sufficient quantities. The review highlights current research demonstrating the efficacy of various probiotic strains in improving shrimp health, boosting immune responses, and reducing pathogen prevalence. Despite their promise, several research gaps remain, particularly regarding the mechanisms of action, strain-specific efficacy, and the impact of probiotics on aquatic ecosystems. Future research should focus on field trials, long-term effects, and the economic feasibility of implementing probiotic treatments in commercial shrimp farming. By addressing these gaps, probiotics could emerge as a best practice in shrimp aquaculture, promoting healthier shrimp populations and fostering more sustainable farming practices.<#LINE#>Wongteerasupaya, C., Vickers, J.
