Research ArticleOpen accessIn the keywordsVirtual Assessment of air Pollution Dispersion from Anthropogenic Sudden ExplosionMarvel Lola Akinyemi, Moses Eterigho Emetere, Mojisola Rachel UsikaluThe control of air pollutants from anthropogenic sources seems almost impossible due to numerous influencing factors present in the atmosphere. In this study, we carried out a virtual mathematical experimentation using Math CAD, Mat lab and analytical approximation to estimate the dimensional impact of initial pollutant plume cloud from a sudden volcanic blast and the dynamics of its wind field. … …American Journal of Environmental Sciences, Vol. 12, Issue 2 · 9 Apr 2016 · 7,157 accessesView PDFCite
Research ArticleOpen accessIn the abstractIncreasing the Critical Micellar Concentration (CMC) of Surfactants Enhances the Removal of Pathogenic Bacteria, P. Aeruginosa, and S. Aureus from WastewaterImen Laadouze, Emna Grami et al.Antimicrobial effects of increasing Critical Micellar Concentration (CMCn) (n varying from 1-12) on Pseudomonas aeruginosa ATCC 27853 and Staphylococcus aureus ATCC 29213 over time of 5-, 10, and 20-minute exposures were evaluated. Three types of surfactants (Cetyltrime Thylammonium Ammonium Bromide (CTAB), Dodecyl Sulfate (SDS), and TX-100) were evaluated. The results showed that CTAB had the greatest impact on both bacterial … …American Journal of Environmental Sciences, Vol. 22, Issue 1 · 8 May 2026 · 1,992 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Hydrodynamic Conditions on Algal Organism GrowthBingxin Zhong, Zhifu Wang, Weihua Feng, Baoxing HuangThe growth of algal organisms is influenced by hydrodynamics, making it a crucial aspect of algal biology. We summarize recent studies on the impact of hydrodynamics on algal growth, with a specific focus on current velocity. In the past, extensive attention has been paid to the direct effects of impact factors on algal blooms and there is still a certain … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 3 · 9 Sep 2024 · 4,932 accessesView PDFCite
