Background: According to 2012 data, the prevalence rate of OA in both rural and urban India was ranging from 33% to 46% of the older adult population where females were more affected than men. Participants with knee OA frequently need to perform strengthening exercises since they have weaker muscles due to decreased physical activity and pain tolerance. Purpose: The Purpose of the study is to find out the efficacy of Muscle energy technique and strengthening exercise in pain management to improve ROM in knee osteoarthritis. Materials and methods: This study included a sample of 196 between the age group of 45- 60 years were taken from Shri Shakthi's centre for pain relief and rehabilitation according to selection criteria for this experimental study which was divided into two groups, strengthening exercise group (n=98) and muscle energy technique group (n=98) . Interventions were given as 5 sessions a week and continued for 2 weeks. Study period: March 2023 to July 2023. Result: The Pre-test and post-test values were analysed, pain score was decreased and functional outcome was improved significantly in strengthening exercise groups when compared to muscle energy technique. Conclusion: The study shows that strengthening exercise for osteoarthritis of the knee in older adults is more effective than muscle energy technique. [ABSTRACT FROM AUTHOR]

Biopolymer composite films comprising strontium titanate crystallites in [(100 - x) Cellulose - xSrTiO3] (0 ≤ x ≤ 90, in wt %) system were fabricated via solution casting technique. The X-ray diffraction (XRD) and scanning electron microscopic (SEM) studies were carried out on these composite films for structural and microstructural analyses. The dielectric constant of these composites increased with the concentration of strontium titanate crystallites dispersed in the cellulose matrix. Different dielectric mixture formulae were employed to rationalize the dielectric properties of the biopolymer composite systems. The composite films also showed promising application towards the removal of toxic chromium(VI). [ABSTRACT FROM PUBLISHER]

The remediation of heavy metals requires the development of efficient adsorbents. Macroporous polystyrene divinyl benzene based resins are known for their excellent surface characteristics for the effective adsorption of metals. In this paper, we propose an effective adsorption procedure for chromium (VI) using aliphatic primary amine as a guest in Amberlite XAD-4 polymeric sorbent as the host. The adsorption of chromium was quantitative at pH 2.5. The adsorption process was in accordance with pseudo second order kinetics and the maximum adsorption capacity was found to be 75.93 mg g−1 with good adherence to Langmuir isotherm model. The free energy change ΔG0 increased with temperature and the negative ΔH0 and ΔS0 values indicate the exothermic nature of adsorption and decreased randomness at the adsorbent-solution interface. In aqueous medium, the water molecules surround the hydrophobic host polymeric matrix and this cage effect is responsible for the reduction in entropy of the system. The regeneration of the adsorbent was effective in alkaline medium and the efficacy of the adsorbent was tested for the removal of chromium from tannery waste water. [ABSTRACT FROM PUBLISHER]
