Abstract Excess emissions are air pollution releases that exceed permitted levels and occur during facility start-ups, shutdowns, or malfunctions. While they violations of the federal Clean Air Act, states have historically granted violating facilities automatic exemptions; limiting enforcement weakening existing regulation. Recent efforts to harmonize state rules ignited debate surrounding opt...

This study evaluates the human health risks in Indian National Capital Territory of Delhi (NCT Delhi) in terms of mortality and morbidity due to air pollution. The spreadsheet model, Risk of Mortality/Morbidity due to Air Pollution (Ri–MAP) was used to evaluate the direct health impacts of various criteria air pollutants present in various districts of NCT Delhi during the period 1991 to 2010....

This paper deals with a novel interactive approach of Artificial Neural Network (ANN) as an optimization tool for optimizing process parameters of rotary furnace. This approach solves a very challenging problem in the area of rotary furnace i. e. selection of optimal process parameters for producing homogenous quality castings. Rotary furnace involves several critical parameters like flame temp...

OBJECTIVES Air pollution has been associated with an increased risk for lung cancer. We examined whether long-term air pollution is associated with bladder cancer risk. METHODS Information from a case-control study in Spain that included 1219 incident cases and 1271 hospital controls was used. Information on residential history including several indicators of exposure to air pollution and oth...

an important property of electromagnetic fields, which arises from the interaction between fields and chiral molecules, is called optical chirality. by enhancing this field property, while maintaining constant input power, we are able to increase absorption of circularly polarized light by chiral molecules of a certain handedness. this enhancement is achieved through the use of achiral plasmoni...

The false legend of carbon dioxide traps resulting from the weight of carbon dioxide gas is disproved. In spite of water-vapor lightness in comparison with air, no water-vapor trap exists on cave ceilings. In fact, underground atmospheres with specific compositions are not related to gravity, but to the absence of any air movement around the gas sources. The process of double diffusion of oxyge...

Purpose of this study is to numerically investigate combustion within a porous channel, which has three layers with different pore densities. Non-premixed inside the channel modelled thermal non-equilibrium energy equations. Flow and chemistry are decoupled tabulated using flamelets, thereby reducing computational cost. GRI 3.0 mechanism used account for methane/air combustion. Simulations perf...

The stability and oxidation of copper nanoparticles stabilized with various ligands have been studied. Lauric acid-capped copper nanoparticles were prepared by a modified Brust-Schiffrin method. Then, ligand exchange with an excess of different capping agents was performed. Oxidation and stability were studied by UV-vis, XRD, and TEM. Alkanethiols and oleic acid were found to improve air stabil...

â â â â â â â  â â â  the excess liquidity of the open economy has become one main factor influencing the monetary markets, financial markets and even the whole macroeconomic. in era of the post-crisis, many countries have implemented the loose monetary policies, especially the quantitative easing policy in the u.s. which worsened the situation of the excess liquidity. under this background, it...
