In this paper, we assume that a professional pollutant treatment enterprise treats all of the pollutants emitted by multiple small and medium-sized enterprises (SMEs). In order to determine the treatment price, SMEs can bargain with the pollutant treatment enterprise individually, or through forming alliances. We propose a bargaining game model of centralized pollutant treatment to study how th...
Background: The undesirable condition of air quality is one of the most important environmental problems that have challenged many of the world's cities. In this study, considering the importance of particle matter as one of the most important atmospheric pollutants in Ahwaz, the main objective is the air quality assessment of this city in terms of PM2.5 and PM10 in 2016-2017. Methods: The air ...
technology transmission has engaged not only developing countries but also many western research communities. foreign direct investment is a commonly used method to transfer the technology. since specific studies on factors affecting the transmission of technology through foreign direct investment has not been made in nanotechnology, the purpose of this study is to identify the issues affecting...
Research indicates that multiple outdoor air pollutants and adverse neighborhood conditions are spatially correlated. Yet health risks associated with concurrent exposure to air pollution mixtures and clustered neighborhood factors remain underexplored. Statistical models to assess the health effects from pollutant mixtures remain limited, due to problems of collinearity between pollutants and ...
Noble metal Ag nanoparticles with unique surface plasmon resonance property have attracted much attention recently in the field of photocatalysis. Based on the advantages of Ag nanoparticles and semiconductor CeO2, a novel plasmonic photocatalyst Ag-AgCl/CeO2 was prepared with a facile route. The as-prepared samples were characterized using scanning and transmission electron microscopy, X-ray p...
The primary objective of this research is to propose and compile a specific protocol for photocatalytic measurements modified TiO2 particles under visible-light irradiation. Nitrogen-modified titanium dioxide (N-TiO2) powder was synthesized by the sol–gel method characterized X-ray Diffraction Analysis (XRD), Field Emission Scanning Electron Microscopy (FESEM), Transmission (TEM), Photoelectron...
Trade liberalization has impacts on the quality of the environment, i.e. on the emission of pollutant gases according to its size, composition and technology. On the other hand, trade liberalization is followed by international capital mobility intensification. Meanwhile according to the Pollution Haven hypothesis, transfer of pollutant industries starts from countries with tough environmental ...
In the present paper, experimental and numerical investigation of a laboratory oil furnace have been done to study the effect of inlet air swirl angle on temperature and generating of pollutant CO and NO. The Concentration of pollutant CO and NO on the centerline of the furnace have been measured using gas analyzer. The numerical results are in good agreement with experimental data. The results...
ABSTRACT A program is developed that includes two hydrodynamic models, a 2D depth-averaged (2DH) and a Quasi-3D (Q3D), and a pollutant transport model that uses a 1 order upwinding and a 3 order QUICKEST numerical schemes. Several tests were performed in two test basins in order to examine the performance of the above models. The Q3D model is successfully applied to Lake Ontario, using a 4-km-s...
