Organic matter from biofilter nitrification by high performance size exclusion chromatography and fluorescence excitation-emission matrix by E.N. Hidayah, W.L. Lai, O.H. Cahyonugroho, F. Rizqa

“…A combination of these methods indicated that the organic matter released during nitrification mainly consists of humic compounds. These results conjecture that a combination of high performance size exclusion chromatography with carbon and ultraviolet detector and fluorescence excitation-emission matrix can be used to determine the characteristic of organic matter and water quality change during nitrification.…”

Modeling Ebola Virus Disease transmissions with reservoir in a complex virus life ecology by Tsanou Berge, Samuel Bowong, Jean Lubuma, Martin Luther Mann Manyombe

“…The reproduction number $\mathcal R_0$ for the full model with the environmental contamination is derived and the global asymptotic stability of the disease free equilibrium is established when $\mathcal R_0 < 1$. It is conjectured that there exists a unique globally asymptotically stable endemic equilibrium for the full model when $\mathcal R_0>1$. …”

Siphon-type hydroelectric plants: application for power generation in a low head dam in southern Brazil by Janaina Terhorst Pizutti, Carlos Henrique Pereira Assunção Galdino, Fernando Setembrino Cruz Meirelles, Alexandre Beluco

“…Solidified in this conjecture, the purpose of this study is to contribute, in the sense of attributing alternatives, for the generation of energy in existing low head dams through the pre-dimensioning of a siphon plant. …”
