An important aspect of the new sustainable development goals (SDGs) is a greater emphasis on reducing the health impacts from ambient air pollution in developing countries. Meanwhile, the burden of human disease attributable to ambient air pollution in sub-Saharan Africa is growing, yet estimates of its impact on the region are possibly underestimated due to a lack of air quality monitoring, a ...
Indoor air pollution (IAP) from household use of biomass and coal is a leading environmental health risk in many developing nations. Much of the initial research on household energy technology overlooked the complex interactions of technological, behavioral, economic, and infrastructural factors that determine the success of environmental health interventions. Consequently, despite enormous int...
Air pollution is a serious problem that affects billions of people globally. Although the environmental and health costs of air pollution are well known, the present research investigates its ethical costs. We propose that air pollution can increase criminal and unethical behavior by increasing anxiety. Analyses of a 9-year panel of 9,360 U.S. cities found that air pollution predicted six major...
Ð Promoting sustainable development requires evaluating the technical and policy options that will facilitate the adoption and use of energy ecient and less polluting cooking stoves and practices. The transition from traditional to modern fuels and devices has been explained by the ``energy ladder'' model that suggests that with increasing auence, a progression is expected from traditional bi...
This is the protocol for a review and there is no abstract. The objectives are as follows: This study aims to assess the effects of intervention strategies that reduce exposure to household air pollution from burning solid fuels on episodes of acute lower respiratory infection (ALRI) in children under the age of 15 years.
Background and objectives: Tehran is one of the most polluted cities in the world in terms of air pollution. Modeling is a useful tool in air pollution management. The objectives of this study are to determine the distribution of the main air pollutants concentration in Tehran and to construct a photochemical model appropriate to the geography and natural characteristics of Tehran. Methods: I...
Anthropogenic activities such as energy consumption, industrial activities and agriculture are major driving forces of emissions of air pollutants. Their future development has a strong influence on the level of future emissions and on the potential and costs for maintaining emissions at environmentally acceptable levels. Unfortunately, it is an ambitious task to accurately model the future dev...
In this paper a new Back-propagation algorithm appropriately studied for modelling air pollution time series is proposed. The underlying idea is that of modifying the error definition in order to improve the capability of the model to forecast episodes of poor air quality. In the paper five different expressions of error definition are proposed and their performances are rigorously evaluated in...
cognitive studies of translation process have recently been awarded a great deal of attention. there exists a psychological angle to almost all translation activities. the present study, thus, deals with analysing the relationships between iranian prospective translators tolerance for ambiguity (ta) and their willingness to translate (wtt). the research was conducted as a mixed methods study, d...
conclusions proximity to road traffic might be a risk factor for ra as there are suspected effects associated with no2 and so2. overall, the available evidence is too preliminary and scarce to draw firm conclusions. however, the results indicate the feasibility of further studies elucidating on the relationship between air pollution and ra. results four relevant papers were included in a qualit...
