The current work demonstrates the feasibility of atmospheric pressure non-thermal plasma technique for NOx pollution control. Atmospheric pressure dielectric barrier discharge plasma reactor has been constructed for the treatment of the exhaust of 4kWs free load diesel engine. The nature and properties of the discharge were identified through studying electrical characterization of the discharg...

The emission control of NOx in exhaust gases is one of the greatest engineering challenges to extend the practical and commercial application of diesel and lean burn engines. One solution is selective NOx reduction using hydrocarbons in an oxidizing atmosphere. We mainly focused on catalytic reactions under temperature excursion because of the resemblance to conditions prevailing in real automo...

Nowadays exhaust emission control from internal combustion engines have become one of the most important challenges. Oxides of nitrogen (NO [email protected] x) are one of the major hazardous pollutants that come out from diesel engines. There are various techniques existing for NOx control but each techniques has its own advantages and disadvantages. Technologies available for NOx reductions e...

BACKGROUND The relationship between inducible nitric oxide synthatase activity and disease severity in leptospirosis is unclear. Nitric oxide is converted to nitrites and nitrates, thus nitrite and nitrate levels (NOx) in serum are considered surrogate markers for nitric oxide. NOx are excreted through the kidneys, and elimination is diminished in renal impairment. We assessed the correlation o...

In this paper, a new physics-based model for the prediction of NOx emissions produced by diesel engines is presented. The aim of this work is to provide a Mean-Value Model (MVM) adapted for control design and online estimation. The proposed approach is based on the simplification of a zero-dimensional thermodynamic model. Only the main phenomena taking part in NOx formation are kept and they ar...

The American electric power industry is undergoing dramatic changes in the way it is structured and regulated. As of June of 1998, state utility regulators, state legislatures or both in 17 states had made the decision to implement retail competition within 5 years or less. Competition in electricity markets and associated new opportunities for expanded interregional electricity trading could r...

Introduction: Repeated hyperglycemia play an important role in development of atherosclerosis in diabetic patients. Endothelium is the first-line defense against atherosclerosis and nitric oxide has a major role in this task. In this study, changes in plasma concentration of nitric oxide metabolites (NOx) during glucose tolerance test were evaluated in type II diabetic rats. Methods: Male neona...

BACKGROUND: Key steps crucial to the process of tumor progression are genomic instability and escape from apoptosis. Nitric oxide and its interrelated reactive intermediates (collectively denoted as NOX) have been implicated in DNA damage and mutational events leading to cancer development, while also being implicated in the inhibition of apoptosis through S-nitrosation of key apoptotic enzymes...

PA Rule Targets Smokestack Pollution In July 2011 the U.S. EPA finalized the CrossState Air Pollution Rule to reduce SO2 and NOX emissions from power plants using available emissions control technologies. SO2 and NOX contribute to ground-level ozone and fine particle pollution and often cross state lines, ending up far from their provenance. The rule is projected to achieve up to $280 billion i...
