The effects of chemical kinetics on oxygen delivery to tissue
(1992)A mathematical model has been formulated to analyze the effect of nonequilibrium kinetics on oxygen delivery to tissue. The model takes into account molecular diffusion, facilitated diffusion in the capillary blood, ... -
A note on Gutierrez's kinetics model for oxygen delivery to tissue
(1992)The problems associated with Gutierrez model (1986, Resp. Physiol. 63, 79-96) on O2 delivery to tissue are discussed. He has used a dimensionally incorrect function for the oxygen dissociation curve (ODC). The dimensionally ... -
The effect of freshwater discharge from the Godavari river on the occurrence of local upwelling off the east coast of India
(1993)A numerical model is described and applied to investigate the combination of the wind- and estuarially-driven circulation of water off the east coast of India. A previous numerical modelling study has shown that the estuarial ... -
Environmental studies of SO2, SPM and NOx, over agra, with various methods of treating calms
(1994)A comparative study between predicted and observed concentrations of major pollutants SO2, suspended particulate matter (SPM) and NOx in Agra, India has been undertaken using two Gaussian plume models. A Gaussian plume ... -
Comparative study of line source models for estimating lead levels due to vehicular traffic in Delhi
(1995)Studies concerning the concentration of lead (Pb)in Delhi due to vehicular traffic are being conducted under sponsorship of Ministry of Environment and Forests, Government of india. The comparison of results of two line ... -
Development of dense gas dispersion model for emergency preparedness
(1995)Mathematical models are recognized as important tools for providing quantitative assessment of the consequences of the aeodental release of hazardous materials. In several accidental release situations, denser-than-air ... -
Sensitivity of Monsoon circulations to changes in sea surface temperatures
(1995)Sensitivity of a regional scale model to different sea surface temperatures (SSTs) in the context of short-range predicuon of monsoon rainfall is studied using a three dimensional regional scale model. For the month of ... -
Surface layer turbulence processess in low wind speeds over land
(1995)The atmospheric diffusion in the tropics is generally associated with low wind speeds, typically of magnitudes less than 3 m s-1. Low wind speeds would cause significant free convection in the daytime and strong stable, ... -
Comparison of sigma schemes for estimation of air pollutant dispersion in low winds
(1995)The dispersion coefficients are key parameters in most of the air quality models and their use in low wind speed conditions involves some degree of uncertainty. Various estimates of dispersion parameters are discussed for ... -
Implications of climatic variations in the fresh water outflow on the wind induced circulation of the bay of Bengal
(1995)A barotropic model is applied to simulate the large-scale ocean circulation in the Bay of Bengal. The driving mechanisms consist, in general, of wind-stress forcing representauve of that applying during the southwest monsoon ... -
Bhopal gas leak: A numerical simulation of episodic dispersion
(1995)A mesoscale meteorological model coupled with a Lagrangmn particle dispersion (LPD) model was used to simulate the Bhopal methyl isocyanate (MIC) gas leak. A simple two layer K-closure version of the Pielke primitive ... -
Atmospheric response to tropical denuding of vegetation
(1995)Two simulations of atmospheric circulations dunng June, July and August 1988 have been made with LMD Atmospheric General Circulation Model using a classified vegetatmn global cover with and without the tropical vegetation ... -
Climate modeling using parallel processors
(1995)A spectral General Circulation Model at horizontal resolutmns T21 and T42 has been integ- rated upto 30 d on 16 and 32 processors of Meiko T800. The model at resoluuon T21 is also implemented on 16 processors (T800) of a ... -
Potential health risks related to carcinogens in the atmospheric environment in india
(1996)In India, rapid urbanization and ndustrialization have contributed positively toward meeting the materialistic needs of the citizens, but have also resulted incontamination of the atmospheric environment. This paper deals ... -
A mathematical model for the dispersion of air pollutant in low wind condition
(Elsevier Science, 1996)For the atmospheric dispersion of pollutants in low wind conditions, a steady-state mathemat- ical model has been formulated which takes into account the diffusion in all the coordinate directions and the advection due to ... -
Statistical evaluations of sigma schemes for estimating dispersion in low wind conditions
(1996)Previously described sigma schemes for the stimation of dispersion parameters in low wind- speed situations are evaluated statistically with the data obtained in a series of diffusion experiments (conducted by U.S. National ... -
