Attitudes to long‐term care in India: A secondary, mixed methods analysis

open access: yesInternational Journal of Geriatric Psychiatry, Volume 39, Issue 6, June 2024.
Abstract Objectives In India, globalisation is purported to have contributed to shifting family structures and changing attitudes to long‐term care (LTC) facility use. We investigated the attitudes to and usage frequency of LTC in India. Methods We conducted secondary analyses of: (a) The Moving Pictures India Project qualitative interviews with 19 ...

Load Contact Analysis and Strength Calculation of Spur Gear

open access: yesJixie chuandong, 2016
Through tooth contact analysis( TCA) and loaded tooth contact analysis( LTCA),the meshing process of spur gear pair is simulated. Based on this,combining with the elasticity theory,the contact stress on each meshing point are calculated.
