Optimizing Street Canyon Orientation for Rajarhat Newtown, Kolkata, India

Gasdynamic Model of Street Canyon

A general proecological urban road traffic control idea for the street canyon is proposed with emphasis placed on development of advanced continuum field gasdynamical (hydrodynamical) control model of the street canyon. The continuum field model of optimal control of street canyon is studied. The mathematical physics approach (Eulerian approach) to vehicular movement, to pollutants’ emission an...

Transport Phenomena in the Urban Street Canyon

1 Abstract A generic proecological traffic control model for the urban street canyon is proposed by development of advanced continuum field hydrodynamical control model of the street canyon. The model of optimal control of street canyon dynamics is also investigated. The mathematical physics' approach (Eulerian approach) to vehicular movement, to pollutants' emission, and to pollutants' dynamic...

Prevalence of Anemia among Street Children in Kolkata, West Bengal, India

Street children are the most neglected and vulnerable population and are at risk of micronutrient deficiency syndrome like anemia. The aim of this study was to assess the nutritional status and prevalence of anemia among street children aged from 3 to 18 years living in Kolkata metropolitan city. Presence of pallor, koilonychias, and blood hemoglobin level were assessed in this survey. A cross ...

Green Walls Could Cut Street-Canyon Air Pollution

Rows of tall buildings can create a unique urban habitat known as a street canyon. These canyons trap traffic pollutants, limiting their dispersal into the atmospheric boundary layer that extends as high as 2,000 meters above the ground. A new study suggests that vegetation in street canyons may reduce air-pollutant concentrations much more than previously reported and suggests innovative plant...
