Research ArticleOpen accessIn the abstractModeling Water Quality in RiversLiren Yu, N. N.B. SalvadorThis study reports a PC software, used in a Windows-based environment, which was developed based on the first order reaction of Biological Oxygen Demand (BOD) and a modified Streeter and Phelps equation, in order to simulate and determine the variations of Dissolved Oxygen (DO) and of the BOD along with the studied river reaches. The software considers many impacts of … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 6,861 accessesView PDFCite
Review ArticleOpen accessAll words, across the recordStudies on Environmental Impact Assessment of Reinforced Concrete in Different Life Cycle PhasesJair Frederico Santoro, Moacir KripkaConcrete is one of most used materials in construction and also one of the main responsible for the emission of carbon dioxide, or CO2, in the atmosphere. Thus, in order to study ways to reduce this impact, it is important to evaluate the influence of each raw material of the reinforced concrete, as well as the phases of the life … …International Journal of Structural Glass and Advanced Materials Research, Vol. 1, Issue 2 · 2 Jan 2018 · 8,218 accessesView PDFCite
