    The COVID-19 has become a public health emergency of international concern. As of April 26, 2020, this pandemic has caused in Morocco more than 4065 confirmed infections and more than 161 reported deaths. To mitigate this epidemic threat and act quickly, it is very important to monitor and analyze changing trends and predict what might happen in the future. The main objective of this paper is to develop a successful prediction. We used in this study at the end of each week the TBATS model to forecast confirmed cases. This model is calculated on the basis of the daily historical data. From the results obtained we can conclude that the predictions obtained are close to reality and for the peak of this epidemic is not yet identified. The obtained results shows that this epidemics will continue to grow. For our forecast from 04/27/2020 to 05/03/2020 we estimate that the number of affected cases will achieve 4367 cases

    Pulsed laser deposition and electrodeposition techniques in growing CdTe and CdxHg1-xTe thin films

    CdTe and CdxHg1-xTe (CMT) thin films were grown by a cathodic electrodeposition technique Also CdTe was deposited using a Pulsed Laser Deposition (PLD) technique. Optical and XPS analysis techniques have been used to characterize them. Important differences were found in adherence, composition, band gap, refractive index, absorption coefficient, really useful for these materials in solar cells. Variables like energy of the laser pulse and temperature of substrate are determinants to improve the structural and optical properties. The presence of Hg in CdTe films is able to control the bandgap although it carries some problems, like segregation and diffusion, found in XPS measurements, that have to be solved. PLD technique could be really of interest in order to avoid this kind of problems.Peer Reviewe
