Association between Physical Fitness and Perceived Well-Being in Functionally Independent Community Dwelling Elderly of North-Eastern India.

Background: Regular physical activity helps in independent living, prevention of chronic health problems and quality of life in the elderly. The aim of the study is to determinewhether physical fitness is associated with multiple dimensions of well-being in the community dwelling elderly.

Materials And Methods: A community-based cross-sectional study was undertaken to assess the physical fitness and perceived wellness in 400 elderly (≥65 years) subjects.

Validity and Test-retest Reliability of perceived Wellness Survey among Geriatric Population: A Community-based Study from North Eastern India.

Chronic illness and functional decline threaten elderly well-being. "Perceived Wellness Survey (PWS)," which measures psychosocial, physical, and intellectual well-being, may be appropriate for assessing the wellness of the geriatric population. This work has been planned to find out the validity and test-retest reliability of a PWS as a wellness-measuring tool for community-based elderly peopleMaterials and methods: This observational study was undertaken in the community was undertaken to assess PWS in 60 elderly individuals (≥65 years).

On the influence of Raman scattering of water in the photoluminescence measurement of water dispersed ZnO nanocrystals.

We present our investigation on the photoluminescence properties of water dispersed ZnO nanocrystals at various excitation wavelengths, and show that one peak in the emission spectrum (recorded by spectrofluorometer) changes its position when the excitation wavelength is changed. The relationship between the peak position and the excitation wavelength is found to be linear. Recording of the emission spectra (by spectrofluorometer) of water at different excitation wavelengths reveals that the linearly varying peak is present in them as well.
