Cowpea is one of the most important legume grains in the sub-Saharan region of Africa used for human consumption and animal feed,but its production is hampered by biotic and abiotic constraints raising the need to broaden its genetic *** this purpose,seeds of two cowpea varieties Melakh and Yacine were irradiated with 300 and 340 Gy of gamma-ray,*** developed mutant populations were agromorphologically characterized from M5 to M7,while the genetic diversity of the latter was evaluated using 13 ISSR *** on the agromorphological characterization,variation of flower color,pod length,seed coat color,and seed weight with 78.01,68.29,94.48,and 57.58%heritability,respectively,were recorded in the mutant *** analyses allowed to identify the elite mutants based on their agromorphological traits,while Pearson’s correlation results revealed a positive correlation between yield and yield component *** subpopulations were identified through STRUCTURE analyses,but the assignment of the individuals in each group was improved using DAPC(Discriminant Analysis of Principal Components)*** of Molecular Variance revealed that the majority(85%)of the variance rather existed within groups than among(15%)***,our study allowed us to select new promising mutant genotypes that could be tested for multi-locational trials to evaluate their agronomic performance.

The operating temperature is a critical factor affecting the performances of photovoltaic(PV)*** this work,relevant models are proposed for the prediction of this operating temperature using data(ambient temperature and solar irradiance)based on real measurements conducted in the tropical *** each weather condition(categorized according to irradiance and temperature levels),the temperatures of the PV modules obtained using the proposed approach is compared with the corresponding experimentally measured *** results show that the proposed models have a smaller Root Mean Squared Error than other models developed in the literature for all weather conditions,which confirms the reliability of the proposed framework.

The all-electric Bus Rapid Transit route in Dakar, built by China Road and Bridge Corp., is set become operational in 2023 Every working day, traffic on the African Union roundabout, midway between Dakar’s popular Colobane area and the Cheikh Anta Diop University, is a nightmare for drivers. It could take ages to pass through this 2-km-long route, which is one of the key crossing points of Senegal’s ambitious Bus Rapid Transit (BRT) initiative to decongest the metropolis.
