A auto-eficácia na adaptação aos desafios do envelhecimento
2017
Este artigo aborda a problemática do envelhecimento com qualidade de vida e bem-estar, estudada no contexto de adultos portugueses que frequentam Universidades Seniores em Portugal. Pretende-se especificamente, numa análise exploratória, conhecer a perceção da auto-eficácia na compreensão do bem-estar e qualidade de vida destas pessoas, através do construto de bem-estar subjetivo (BES). Para o efeito, foi realizado um trabalho empírico de natureza não experimental correlacional, que abrangeu 214 alunos de 7 Universidades Seniores portuguesas, com idades compreendidas entre os 51 e 86 anos, média de 68,26 anos. Os dados foram recolhidos por questionário, através dos seguintes instrumentos: q…
Absorption kinetics and swelling stresses in hydrothermally aged epoxies investigated by photoelastic image analysis
2015
Abstract The present work proposes an experimental optical methodology able to measure the transient swelling stresses induced by the water uptake ageing of polymers. In particular, the work describes the implementation of a Photoelastic technique to quantify internal stresses arising during the hydrothermal ageing of cast epoxy samples. The material investigated is a model DGEBA/DDS epoxy system. Curing and post-curing cycles have been optimised in order to obtain a fully cured, high T g , and completely stress free initial condition. Rectangular beam samples were then left in a hydrothermal bath at 90 °C, and regularly monitored by gravimetric and photoelastic analyses. The quantitative e…
Basalt Fibre Composite with Carbon Nanomodified Epoxy Matrix under Hydrothermal Ageing
2021
This work aimed to investigate the effect of hybrid carbon nanofillers (e.g., carbon nanotubes/carbon nanofibers in the ratio 1:1 by mass) over the electrical and flexural properties for an epoxy matrix and corresponding basalt fibre reinforcing composite (BFRC) subjected to full-year seasonal water absorption. Hydrothermal ageing was performed by full immersion of the tested materials into distilled water according to the following model conditions (seasons). The mechanical properties were measured in three-point bending mode before environmental ageing and after each season. Upon environmental ageing, the relative change of flexural strength and elastic modulus of the epoxy and NC was wit…
Durability of Biodegradable Polymer Nanocomposites
2021
Biodegradable polymers (BP) are often regarded as the materials of the future, which address the rising environmental concerns. The advancement of biorefineries and sustainable technologies has yielded various BP with excellent properties comparable to commodity plastics. Water resistance, high dimensional stability, processability and excellent physicochemical properties limit the reviewed materials to biodegradable polyesters and modified compositions of starch and cellulose, both known for their abundance and relatively low price. The addition of different nanofillers and preparation of polymer nanocomposites can effectively improve BP with controlled functional properties and change the…
Spa tourism as a part of ageing well
2019
Due to increased life expectancy and the prevailing ideological elements of wellness and active ageing, wellness-related consumption has become a distinctive part of many retirees’ lifestyles in af...
Co-created training program to promote active ageing in people with Down syndrome
2020
Abstract Background Population ageing is a current challenge for the European society. Specifically, People with Down Syndrome (PDS) are living longer than before, reaching some of them around 60 years old. However, it is known that they show premature ageing that in some cases may be misled with Alzheimer first signs. Hence, it is crucial to promote an Active Ageing (AA) and healthy living in this specific population by keeping their cognitive, physical and emotional functions, and also promoting social activities such as community participation. In such way, their Quality of Life (QoL) will be increased. Objectives The main objective of this study was to co-design a Training Program (TP) …
Perspectives on Dynamic Retirement and Active Ageing
2014
One central goal in ageing individuals’ late-career stages is to participate in working life, subsequently transition successfully into retirement, and to lead a satisfying and healthy life in retirement. In many ways, these goals are aligned with the policy orientation of countries facing challenges with global ageing. This chapter describes some of the current themes of retirement and late-career research, with a specific interest on the role of individual resource allocation strategies and human resource management in promoting the work ability of older employees. It will present the concept of bridge employment in the Finnish context, and the effects of normal retirement, i.e. after rea…
THE REFERENCE SITE COLLABORATIVE NETWORK OF THE EUROPEAN INNOVATION PARTNERSHIP ON ACTIVE AND HEALTHY AGEING
2019
International audience; Seventy four Reference Sites of the European Innovation Partnership on Active and Healthy Ageing (EIP on AHA) have been recognised by the European Commission in 2016 for their commitment to excellence in investing and scaling up innovative solutions for active and healthy ageing. The Reference Site Collaborative Network (RSCN) brings together the EIP on AHA Reference Sites awarded by the European Commission, and Candidate Reference Sites into a single forum. The overarching goals are to promote cooperation, share and transfer good practice and solutions in the development and scaling up of health and care strategies, policies and service delivery models, while at the…
Association of Klotho Polymorphisms with Healthy Aging: A Systematic Review and Meta-Analysis
2013
Today it is clearly evident that genetic background constitutes an integral part of aging and longevity. Many studies on long-lived people have been conducted emphasizing the role of certain genes in long life. Classic case-control studies, genome-wide association studies, and high-throughput sequencing have permitted identification of a variety of genetic variants seemingly associated with longevity. Over the years, aging research has focused on the insulin/insulin-like growth factor-1 (IGF-1) signaling pathway because of its evolutionarily conserved correlation with life-span extension in model animals. Indeed, many single-nucleotide polymorphisms (SNPs) associated with longevity were ide…
