Reservoir operation simulation for existing and planned hydropower projects on the Niger and Benue catchments in Nigeria
Published 2022-01-01“…The modelling approach was based on maximizing energy production and maintaining a target mean load factor. (1) Impacts of reservoir development on hydropower production benefits, downstream flow variability, navigation downstream for three time horizons: current, mid development and maximum potential development. (2) Sensitivity analyses of water availability risks for hydropower generation for the three selected sites considering possible future abstractions and projected climate change. (3) Optimization of the use of the River Niger’s White flood in Nigeria and study of the augmentation of the Kainji HPP in order to mitigate the potential future production losses due to upstream developments/abstractions outside Nigeria.…”

Improving the productivity of malic acid by alleviating oxidative stress during Aspergillus niger fermentation
Published 2022-12-01“…Transcriptome and biochemical analyses demonstrated that both antioxidant enzyme-mediated oxidative stress defense system, such as superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPX), and nonenzymatic antioxidant system, such as glutathione, were enhanced in the presence of elastin peptide, suggesting elastin peptide relieving oxidative stresses is involved in many pathways. In order to further investigate the relationship between oxidative stress defense and malic acid productivity, we overexpressed three enzymes (Sod1, CAT, Tps1) related to oxidation resistance in A. niger, respectively, and these resulting strains display varying degree of improvement in malic acid productivity. …”
