ABSTRACT
The aim and objective of this research study was to compare the nutritional status of Severe Acute Malnourished (SAM) Children between Pre and Post admission in Nutrition Rehabilitation Center (NRC). The exploratory as well as descriptive research design was used. The nutritional status was checked by four test variables as Weight-kg, Height-cm, MUAC (Mid-Upper Arm Circumference). The sample size of this study was 211. The normality test was performed using One-Sample Kolmogorov-Smirnov Test. Since the data of four test variable was not normal, hence non-parametric test (Wilcoxon Signed Ranks Test) was used for the comparative study between pre and post condition. The findings concluded that there was a difference of the weight, height, MUAC, of the children in pre and post medical treatment in the NRC for the SAM children.
ABSTRACT
Cognitive impairment (CI) is no longer considered a normal and inevitable change of aging. This study was carried out to assess extent, spectrum, and predictors of cognitive impairment in the participants. Acommunity?based cross?sectional study was done on 616 urban geriatric participants of Varanasi city selected by multistage sampling procedure. The participants were interviewed about their sociodemographic profile using a predesigned and pretested pro forma, and their cognition was assessed through Mini-Mental State Examination tool. Logistic regression analysis was applied for an inferential purpose. Adjusted odds ratios (AORs) and 95% confidence interval were computed. Extent of cognitive impairment in geriatric participants was 22.4%. AORs were maximum in ?80 years (21.23; 95% Confidence Interval: 7.05–63.94), in illiterate and just literate participants (13.71; 95% Confidence Interval: 6.49–28.98) and in homemakers (17.0; 95% Confidence Interval: 4.28–67.49). Nine out of 40 urban geriatric participants had cognitive impairment. Adversities of cognitive impairment were more with advancing age, nonengagement in gainful employment, and low literacy levels.
ABSTRACT
Presence of pathogens in high numbers in waste water is a cause of concern. Techno economic feasibility has restricted the conventional and non conventional treatment approaches for pathogen removal. Despite prolific use, carbon adsorption technology remains an expensive treatment process. The present study investigates the use of rice husk (RH), saw dust (SD), groundnut shells (GS) as natural agro-residues and partially weathered deccan trap basalt (PWDTB) for their sorption capacities and desorption pattern for two indicator organisms viz. Escherichia coli K12 and Staphylococcus aureus. Sorption experiments were carried out at flow-rate of 1.5 bed volumes per hour (bv hr-1) for cell suspension volume of 4, 8, 16 and 32 bed volumes. PWDTB have shown high sorption coefficient and log removal for E. coli K12 whereas GS have shown high sorption coefficient and log removal for S. aureus. PWDTB have shown maximum desorption constant and log retention for E. coli K12 whereas GS have shown maximum desorption constant and log retention for S. aureus during desorption experiment. Retention pattern suggest that adsorption is partially irreversible for almost all the materials used. It suggest that PWDTB in combination with RH and / GS could help in removal of pathogens from waste water.
ABSTRACT
In the present study arsenate and arsenite removal from naturally available red soil in and around Western Ghats of Maharashtra near Mumbai has been investigated. The parameters like adsorbent dose, operating pH, contact time, initial arsenite concentration, adsorbent particle size, etc. on the removal of arsenite and arsenate are examined. Kinetic study in centrifuge vessel reveals that uptake of As (III) ions is rapid in the first two hours and slows down thereafter. Maximum removal efficiency of As (III) achieved is 98% at an adsorbent dose of 45 g l-1 with initial As (III) concentration of 1000 1g l-1 in batch studies and 95% at 25 g l-1 absorbent dose under the same conditions. Equilibrium time is almost independent of initial arsenite concentration. Equilibrium studies show that As (III) ions have high affinity towards red soil even at very low concentration of arsenite. In speciation study, about 25% conversion to As (V) from As (III) is observed, with initial As (III) concentration of 1000 1gl -1 and at 25 g l-1 adsorbent dose. The results suggest that red soil could be used as effective filter medium for removal of arsenic from water.
