Enhanced Tetracycline Removal from Highly Concentrated Aqueous Media by Lipid-Free Chlorella sp. Biomass
(2022-04-14)
Microalgae are used as a lipid source for different applications, such as cosmetics and biofuel. The nonliving biomass and the byproduct from the lipid extraction procedure can efficiently remove antibiotics. This work has ...
Identification and Quantification of Microplastics in Effluents of Wastewater Treatment Plant by Differential Scanning Calorimetry (DSC)
(2022-04-20)
In this research, the presence of microplastics was detected through a differential scanning
calorimetry (DSC) analysis of three wastewater treatment plants. One of these plants applied

Parametric Analysis of a Mechanical Draft Cooling Tower using Two Mathematical Models
(2021-06-25)
In the present work, a Matlab® computer code for cooling tower simulation was developed to perform a parametric analysis
that determines the effect of the column cross-sectional area on multiple operating variables such ...
On nearly S-paracompactness
(2021-08-12)
- The objective of the present work is to introduce the notion of α-nearly S-paracompact subset, which
is closely related to α-nearly paracompact and αS-paracompact subsets. Moreover, we study the invariance under
direct ...
