This study conducts a strategic stakeholder analysis of Morocco’s Advanced Metering Infrastructure (AMI) within the country’s broader energy-transition reforms. It employs a qualitative triangulation design, combining semi-structured interviews, deep documentary analysis, and relational mapping. Results highlight a centralised governance pattern in which public institutions, international donors,…

Background: The increasing demand for plant-based dairy alternatives has highlighted almond milk as a popular option due to its favorable sensory properties and suitability for individuals with lactose intolerance or milk protein sensitivity. However, its inherently low levels of calcium and vitamin D3 limit its nutritional equivalence to cow’s milk, particularly in populations with higher minera…

Three new Schiff base compounds (S1-S3) from 1-([1,1'-biphenyl]-4-yl)ethan-1-amine and substituted-benzaldehydes are synthesized and biologically evaluated in this work. After microwave-assisted synthesis, the compounds were purified and structurally characterized by FTIR, 1H-NMR, and 13C-NMR. Agar diffusion was used to test their antibacterial activities against pathogens such Staphylococcus aur…

This determined the electrical characteristics of the six-naphthalene bridge tetracyanoquinodimethane dye that were suggested. The characteristics were determined by plotting energy and temperature against one another. The SIESTA-trunk-426 program was used for the relaxation of the dyes under study by employing the Generalized Gradient Approximation/Double Zeta Density Functional Theory (GGA/DZ-D…
