    The degradation of methylene blue by bacterial strains isolated from the peel of Red Beet
    (Université M'Hamed Bougara Boumerdes, 2018) Abai, N.; Abed, F.; Babakhouya, N.; Benrachdi, K.
    The textile industry generates half of the industrial pollution flows, these effluents can be very colorful and difficult to treat. The treatment of these effluents has become a priority in the world, the development of methods and the optimization of existing processes, are the subject of a large number of works. In the present work the methylene blue was degraded by two bacterial strains BP1 and BP2 isolated from the peel of red beet, identified as Acinetobacter Johnson II BP1 and BP2 as Bacillus weihenstephanensis. The effect of the initial concentration, pH, temperature, and addition of the carbon source and nitrogen source on the biodegradation of the dye was determined.

    Analysis of climatic drought using drought indices in algiers region
    (Aljest, 2019) Ladji, H.; Benrachdi, K.; Djoumad, Sonia
    Our research consists on the one hand to study the evolution of the rainfall data and the annual and monthly temperatures observed in the Algiers region and on the other hand to analyze the sequences of the climatic drought in using statistical methods such as drought indices. The statistical study of rainfall series in the Algiers region reveals a large variation of the wet and the dry years in space and time. The series of measurements of 1967-2015 are repeated in years of drought (moderate or high). Indeed, the last three decades (1980, 1990 and 2000) are particularly concerned by this situation of annual rainfall deficit.
