A microclimate classification of the entire Bologna Municipality has been carried out in order to give a tool local administration drafting General Urbanistic Plan (PUG). The city was classified considering variation air temperature as function surface characteristics, vegetation fraction, building density and H/W ratio (height width). Starting from analysis with fluid-dynamic modeling (Envi-me...

T h e application of the polymerase chain reaction ~l-s~ (PCR) to explore various areas of envi ronmenta l microbiology has the potential to solve m a n y difficult and unanswered questions about microbial activities in the env i ronment at the physiological and molecular levels. This review describes the use of PCR for the detection of specific microbes in envi ronmenta l samples and discusses...

With the wind permanent flow in the cities, obtaining the minimal pollution in the environment is accessible. Different policies have been considered for optimization of cities such as attachment and or reduction of building parts like air-traps, ceiling forms and so on. Due to population growth in cities and the increasing need for resettlement these people in the cities, inevitably, to the hi...

Greening of facades is a non-expensive option to increase the amount of vegetation in urban areas. Especially in areas with dense settlement, the filtering effect of facade greening can improve urban air quality. In this paper, results from field experiments and numerical simulations are presented. Using Atomic Absorption Spectrometry the amount of heavy metals on leaf samples from seven houses...

In this study, we apply the ENVI-met model to evaluate effects of combinations morphological and vegetation-related landscape features on urban temperatures thermal comfort. We simulated conditions 126 scenarios, varying aspect ratios street canyons, vegetation cover density, surface materials, orientations toward prevalent winds under an extreme heat situation. Our results show how physical pa...

As stated by the World Health Organization (WHO), air pollution in urban environment is silent cause for around seven million death worldwide. This due to indoor and outdoor exposure various pollutants emitted built environment: as global trend an increase of population living towns, this issue predicted become even worser. a matter fact, can trapping instead their dispersion. In work, dispersi...
