Reclamation of Dye Affected Soil at Tirupur Region by Using Vermitechnology, South India

Soil from the dye affected area is taken for various analysis. Similarly soil from the fertile land is also taken for analysis in the same region. Most of the soils polluted by heavy metals can be reclaimed using a number of expensive tactics that either remove the contaminants or stabilize them within the soil .To analyze the parameters such as soil pH, temperature, soil fungal, bacterial and actinomycetes population of both the samples. Find out what are the metals present in the soil samples. Apply vermicompost to the dye affected soil for reclamation. Again we should analyze soil pH, temperature, fungal, bacterial and actinomycetes population of both the soil samples .The results are discussed with the literature.----------------------------------------------------------------------------------V.

Racemic epinephrine compared to salbutamol in hospitalized young children with bronchiolitis; a randomized controlled clinical trial [ISRCTN46561076]

BACKGROUND: Bronchiolitis is the most common cause of lower respiratory tract illness in infancy, and hospital admission rates appear to be increasing in Canada and the United States. Inhaled beta agonists offer only modest short-term improvement. Trials of racemic epinephrine have shown conflicting results. We sought to determine if administration of racemic epinephrine during hospital stay for bronchiolitis improved respiratory distress, was safe, and shortened length of stay. METHODS: The study was a randomized, double-blind controlled trial of aerosolized racemic epinephrine compared to salbutamol every one to 4 hours in previously well children aged 6 weeks to ≤ 2 years of age hospitalized with bronchiolitis. The primary outcome was symptom improvement as measured by the Respiratory Distress Assessment Instrument (RDAI); secondary outcomes were length of stay in hospital, adverse events, and report of symptoms by structured parental telephone interview one week after discharge. RESULTS: 62 children with a mean age of 6.4 months were enrolled; 80% of children had Respiratory Syncytial Virus (RSV). Racemic epinephrine resulted in significant improvement in wheezing and the total RDAI score on day 2 and over the entire stay (p < 0.05). The mean LOS in the epinephrine arm was 2.6 days (95% CI 2, 3.2) v. 3.4 days in those in the salbutamol group (95% CI 2.6, 4.2) (p > 0.05). Adverse events were not significantly different in the two arms. At one week post-discharge, over half of parents reported that their child still had a respiratory symptom and 40% had less than normal feeding. CONCLUSION: Racemic epinephrine relieves respiratory distress in hospitalized infants with bronchiolitis and is safe but does not abbreviate hospital stay. Morbidity associated with bronchiolitis as identified by parents persists for at least one week after hospital discharge in most infants

COMPARISON OF BACTERIAL FORAGING OPTIMIZATION AND ARTIFICIAL BEE COLONY OPTIMIZATION TECHNIQUE FOR DISTRIBUTED GENERATION SIZING AND PLACEMENT IN AN ELECTRICAL DISTRIBUTION SYSTEM

Integration of Distributed Generation (DG) in an electrical distribution system has increased recently due to voltage improvement, line loss reduction, environmental advantages, and postponement of system upgrading, and increasing reliability. Improper location and capacity of DG may affect the voltage stability on the Distribution System (DS). Optimization techniques are tools used to predict size and locate the DG units in the system, so as to utilize these units optimally within certain limits and constraints. The DG units’ sizing and placement is formulated using mixed-integer nonlinear programming, with an objective function of improving the system stability margin; the constraints are the system voltage profile, feeders’ capacity, power factor and the DG penetration level. In this paper the optimal sizing and DG placement in distribution systems is presented using Bacterial Foraging Optimization (BFO) and compared with Artificial Bee Colony Optimization (ABCO) algorithm. Two scenarios of DG are considered with some test cases indicate that BFO method can obtain better results than the BCO search method on the 69-bus radial distribution systems

Ceria-supported platinum as hydrogen-oxygen recombinant catalyst for sealed lead-acid batteries

Ceria-supported platinum synthesized by a novel solution-combustion method results in ionically substituted platinum sites on nanosized ceria crystallites, and is found to be an excellent hydrogen and oxygen recombinant catalyst at room temperature for recovery of water in sealed lead-acid batteries. The use of this catalyst prevents any change in the quantity or concentration of the sulfuric acid electrolyte in the battery during its operation, which is pivotal to enhancing both its performance and life span. The catalyst could be equally advantageous to alkaline storage batteries, and, in particular, in realizing sealed nickel-iron batteries giving them a revived commercial interest
