In recent years, the nanotechnology has gained much attention since the nanoparticles (NPs) have applications in every field of life. The hetero-structured are of special interest due to their higher photocatalytic activity. In present investigation, Zinc vanadate NPs were synthesized from vanadium and zinc salts by microwave assisted precipitation method. The Zinc vanadate NPs were characterized by x-ray Powder Diffraction (XRD), Energy-dispersive x-ray spectroscopy (EDX), Scanning electron microscope (SEM) and UV-visible techniques. The photocatalytic activity (PCA) was evaluated by degrading the methylene blue (MB) dye and process variables were optimized. The Zinc vanadate size was <100 nm and particles were in aggregates form. The MB dye degradation was performed at different conditions of process variables and it was observed that MB dye was significantly degraded using Zinc vanadate NPs under UV light irradiation. The reaction time, catalyst dose and dye initial concentration showed variable effect on dye degradation. Based on results, it can be concluded that the microwave irradiation is viable for the synthesis of Zinc vanadate NPs for photocatalytic activity. In view of promising efficiency of Zinc vanadate NPs, it can be used for the dye degradation and for the remediation of textile effluents.
Traumatic brain injury (TBI) occurs as a result of an outside force, e.g. a blow to the head in a fall or traffic accident, and is a major cause of death and disability all over the world, especially in children and young adults.Objective: To determine the Assessment of health related quality of life in post traumatic brain injury. Methods:It was the cross-sectional observational study. Data was collected by 40 TBI patients on basis of inclusion and exclusion criteria. Quality of life after traumatic brain injury questionnaire was used in this study to see the QoL in post TBI patients.Results: In general males were more affected then females and main reason of TBI was motor bike. The quality of life much affected in feeling, physical work and social relationship. The QoL didn’t depend upon time since injury but depend on severity of injury. Conclusion: Physical work issue was the fundamental predictive factor of hundered personal satisfaction of TBI individuals perhaps, there was no relationship among impairment and QoL. This change of QOL has clinical implications and features the need of more endeavors to improve the rehabilitation interventions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
