To date five different theories compete in explaining the biological mechanisms of senescence or ageing in invertebrates. Physiological, genetical, and environmental mechanisms form the image of ageing in individuals and groups. Social insects, especially the honeybee Apis mellifera, present exceptional model systems to study developmentally related ageing. The extremely high phenotypic plastic...

In longitudinal studies, changes in participants’ cognitive performances can partly be attributed to variations in the testing situation (testing specific factors), such as, different test administrators or different testing environments. Focusing on test administrator influence, testing specific factors were examined in a Swedish longitudinal study of ageing. Test scores from 6,686 examination...

We describe the Smart Ageing, a serious game in a 3D virtual environment aimed at the early detection of Mild Cognitive Impairments in persons ageing between 50 and 60, and at assessing cognitive impairments in persons already diagnosed or having neurodegenerative dementia. Smart Ageing is a telematic system in which users realize a set of screening tests structured in five daily-life tasks in ...

The paper aims to examine the population ageing as a new phenomenon effecting rural areas in Iran. Population ageing is going up throughout the country especially in the rural areas by 6.8 percent. fertility decline, increase in the youth migration to cities, and coming back to rural areas after retiring are the major factors which involve in rural ageing. This may jeopardize the communities. f...

Purpose: The goal of the study is to research the effect of various time of ageing on corrosion resistance, hardness and structures of Remanium 2000+ Co-Cr-Mo alloys used in prosthodontia. Design/methodology/approach: To investigation was prepared mould, cast in 1430°C and realized the heat treatment: solutioning in 1250°C by 3 hours and then ageing in 850°C by 4, 8, 16 and 24 hours. Electroche...

Active ageing level and its discrepancy in different regions (Bangkok, Central, North, Northeast, and South) of Thailand have been examined for prioritizing the policy agenda to be implemented. Attempt has been made to test preliminary active ageing models for Thai older persons and hence active ageing index (AAI, ranges from 0 to 1) has been estimated. Using nationally representative data and ...

introduction: elder abuse may increase the vulnerability of ageing people to disease and decrease their general health status, so addressing the issue is essential for promoting elderly quality of life. the study aimed to examine the relation between abuse experience and general health among elderly people in yazd city- iran. methods: the cross-sectional study carried out on 250 community-dwell...
