performance of an air-lift reactor (ALR) have traditionally considered bulk gas
and liquid phase characteristics. This study aims to present an alternative
approach of modelling an ALR by estimating the energy input to the reactor and
gas hold-up in the riser based on dynamics of individual bubbles. The bubbles
have been assumed to rise in discrete layers in the riser having a diameter in
equilibrium with the surrounding pressure. The model predictions of gas hold-up
and liquid velocity in the downcomer for ALRs have been compared with the
reported experimental data.</span
Adsorption Characteristics of Activated Carbon for the Reclamation of Eosin Y and Indigo Carmine Colored Effluents and New Isotherm Model
The adsorption response of eosin Y and indigo carmine acid dyes on activated carbon as a function of system temperature for a fixed concentration was investigated at various temperatures via adsorption isotherms and their thermodynamic quantities such as enthalpy, entropy, and Gibbs free energy changes. The adsorption data were exploited to develop a new adsorption isotherm. The new isotherm was developed with the spirit of solid–liquid phase equilibrium and regular solution theory. The proposed model has four adjustable constants and correlates adsorption isotherm in terms of the system temperature and melting temperature of the dye. The effect of pH on the removal of acid dyes was reported. The pH variation was observed to affect the adsorption efficiency. The removal of eosin Y and indigo carmine decreased from 99.4% to 82.6% and 92.38% to 79.48%, respectively, when the pH of the solution varied from 2 to 12. The thermodynamic analysis of the process reveals that the process of the removal of acid dyes is exothermic and spontaneous. Moreover, the kinetics parameters of the batch process are reported
CEFTRIAXONE RELATED ADVERSE DRUG REACTIONS IN CHILDREN IN A TERTIARY CARE HOSPITAL, KOLKATA, WEST BENGAL, INDIA
Ceftriaxone is a third-generation cephalosporin antibiotic, which has broad-spectrum
activity against Gram-positive and Gram-negative bacteria. It is a frequently used antibiotic in children
worldwide. Studies revealed a number of adverse reactions related to this third generation antibiotic.
A survey was done where data related with adverse drug reactions (ADRs) were collected for three
months from the Department of Pediatrics of a tertiary care hospital, Kolkata, West Bengal, India
and then evaluated. In the study, fifteen ADRs were detected. Ceftriaxone itself or its combinations
correlated with more than thirty three percent (33.4%) adverse reaction cases in this study. Most
common adverse drug reactions in the present study population were different types of rashes like
urticaria and maculopapular eruptions
