Abstract: This article examines the effects of charge, engine speed, ignition timing, and air-fuel ratio on the temperature of exhaust gases when using biogas as fuel. The effects of varying engine operating conditions on exhaust gas temperature are analyzed. The article discusses whether increasing engine charge and engine speed leads Leia mais…
Abstract: This article investigates the effects of intake manifold pressure and engine speed on the volumetric efficiency of an internal combustion engine. The study also examines the impact of biogas and different temperatures on volumetric efficiency. Through analysis, it’s verified if the volumetric efficiency of the engine decreases when using Leia mais…
Abstract: The O&G production corrosion challenges are not static phenomena. Fluid characteristics change over time, resulting in systems becoming less predictive for corrosion mitigation programs. Thus, carrying out specific studies aimed at understanding the corrosion mechanisms is constant in this sector, especially for offshore environments. Even though, few studies of Leia mais…
Abstract: Occupational exposure to toxic elements can adversely affect health. The current study evaluated blood concentrations of potentially toxic elements (PTE) including As, Cd, Cr, Cu, Hg, Mn, Ni, Pb, Sb, Sn, and Zn in formal and informal workers. Additionally, the study investigated the associations between blood PTE concentrations and Leia mais…

Abstract: Internal corrosion is one of the main problems related to the integrity of pipelines. It depends on the type of material used in the manufacture of the tubes and the composition of the fluid. Generally, the material used is carbon steel which, despite having low cost and good weldability, Leia mais…
