Based on the expert-novice analysis, we developed a distributed scaffolding curriculum for modeling air quality (DSCMAQ) to facilitate high school students’ modelbased reasoning in a technology-enhanced learning environment (APoME) which provided the Modeling Air Quality (MAQ) software associated with gradual complex learning tasks. Three studies had conducted to evaluate the effects of DSCMAQ ...

air pollution is one of the major threats to environment in the present time. increase in degree of urbanization is a major cause of this air pollution. due to urbanization, vehicular activities are continuously increasing at a tremendous rate. mobile or vehicular pollution is predominantly degrading the air quality worldwide. thus, air quality management is necessary for dealing with this seve...

the air quality in shiraz was assessed based on a one-week passive sampling campaign.during the first week of the summer 2003, about 400 passive samplers were used in groups of two andthree, so that 187 sampling stations covered all of shiraz. pollutant gases including so2, no2 and btx(benzene, toluene and xylene) were sampled by diffusive sampling tubes. collected samples wereanalyzed and poll...

introduction: various types of software are used in health care organizations to manage information and care processes. the quality of software has been an important concern for both health authorities and designers of health information technology. thus, assessing the effect of software quality on the performance quality of healthcare institutions is essential. method: the most important healt...

Background: Air pollution and concerns about health impacts have been raised in metropolitan cities like Tehran. Trend and prediction of air pollutants can show the effectiveness of strategies for the management and control of air pollution. Artificial neural network (ANN) technique is widely used as a reliable method for modeling of air pollutants in urban areas. Therefore, the aim of current ...

introduction reducing and optimizing energy consumption and consequently environmental pollution reductions, besides improving building performance providing occupants comfort conditions, make the building's concept closer to the concept of green building and sustainability. once the decision to build green has been made, one of the first steps in the green design process is to establish f...

Air quality simulations and forecasting using photochemical transport models require detailed information of the emissions in the area under investigation. Due to the wide range of space and time scales involved in the physical and chemical processes of air pollution phenomena, a need to perform air quality simulations over larger regions, at finer grid resolutions, using more emissions sources...

swelling urban populations and increasing number of industry and especially automobiles in and around cities have resulted in adverse effect on human health. one of the most important things regarding air pollution in these days is that the number of motor vehicles has increased, and the resulting problems of new types of air pollution on large scale need to be emphasized in large cities.the gr...

Models-3, a flexible software framework, and its Community Multiscale Air Quality (CMAQ) modeling system form a powerful third generation air quality modeling and assessment tool designed to support air quality modeling applications ranging from regulatory issues to science inquiries on atmospheric science processes. The CMAQ system can address tropospheric ozone, acid deposition, visibility, f...
