Integrated risk analysis for acute and chronic exposure to toxic chemicals
(2003)
The traditional practice to assess and evaluate different types of risk in isolation to each other are liable to give erroneous results. Integrated risk assessment is an answer to overcome this problem. This paper presents ...
Dispersion of pollutants in convective low wind: a case study of Delhi
(2002)
The transport and dispersion of pollutants becomes weak under low wind conditions resulting in large ground level concentrations (g.l.c.'s). Largest mean g.l.c.'s due to elevated sources are typically found under daytime ...
Simulation of short-range diffusion experiment in low-wind convective conditions
(2002)
A previously obtained analytical solution to model the short-range dispersion of pollutants in low winds from surface releases has been used to simulate diffusion tests conducted during winter in weakly convective conditions ...
Effect of winds on SO2 and SPM concentrations in Delhi
(2002)
A study of concentrations of sulfur dioxide (SO2) and suspended particulate matter (SPM) has been performed in Delhi. The monthly and seasonal variations of concentrations and winds are analyzed. The monthly mean SO2 ...
Two-dimensional analytical model for estimating crosswind integrated concentration in a capping inversion: eddy diffusivity as a function of downwind distance from the source
(2001)
A mathematical model has been proposed for computing crosswind-integrated concentration in a capping inversion layer by considering the eddy diffusivity as a function of down wind distance from the source. An analytical ...
Emission estimates and trends (1990–2000) for megacity Delhi and implications
(2004)
A comprehensive emission inventory for megacity Delhi, India, for the period 1990–2000 has been developed in support of air quality, atmospheric chemistry and climate studies. It appears that SO2 and total suspended particles ...
A compartmental model for oxygen transport in brain microcirculation in the presence of blood s
(2002)
A compartmental model is developed for oxygen (O2) transport in brain microcirculation in the presence of blood substitutes (hemoglobin-based oxygen carriers). The cerebrovascular bed is represented as a series of vascular ...
A compartmental model for oxygen transport in brain microcirculation in the presence of blood substitutes
(2002)
A compartmental model is developed for oxygen (O2) transport in brain microcirculation in the presence of blood substitutes (hemoglobin-based oxygen carriers). The cerebrovascular bed is represented as a series of vascular ...
On the bulk Richardson number and flux–profile relations in an atmospheric surface layer under weak wind stable conditions
(2003)
For describing the surface fluxes in the atmospheric dispersion models, the commonly used linear universal similarity functions m and h for nondimensional wind and temperature profiles (J. Atmos. Sci. 28 (1971) 181; ...
Present scenario of air quality in Delhi: a case study of CNG implementation
(2003)
The present study discusses the ambient air quality of Delhi from the point of view of change of diesel by Compressed Natural Gas (CNG) in transportation in Delhi. Several initiatives were taken to reduce extremely high ...
