Research ArticleOpen accessIn the abstractAdsorption and Descaling of Cellucotton and Chitosan-Modified Bentonite for Produced WaterTao Yu, Ying Wang, Chengtun Qu et al.The compatibility of non-identical layers within the water present in the produced oil is poor and ion reactions in the oil mixed with water result in scale formation, thereby having a significant impact on oilfield safety production. In this study, methods for the descaling of produced water from different blocks were studied according to the quality characteristics of the produced … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 2 · 18 May 2020 · 6,664 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeneral Approach for Formulating a Digital Transformation StrategyZineb Korachi, Bouchaib BounabatTo take advantage of information technologies, organizations need to define a clear strategy. Numerous works have provided definitions and phases of digital strategies. Some of these strategies are context-specific, while others deal with the common elements of digital strategies regardless of the digital transformation context. However, these works do not address a holistic approach. This raises ambiguity regarding digital strategy … …Journal of Computer Science, Vol. 16, Issue 4 · 27 Apr 2020 · 10,874 accessesView PDFCite
