This paper examines the contributions that generativity in older age maymake to the concept of successful ageing. To this end, two perspectives on successful ageing are described: successful ageing as a set of clinical criteria, and successful ageing as the application of adaptive processes aimed at achieving efficient functioning. After showing the limitations of the first perspective, particu...

Studies in invertebrate model organisms have led to a wealth of knowledge concerning the ageing process. But which of these discoveries will apply to ageing in humans? Recently, an assessment of the degree of conservation of ageing pathways between two of the leading invertebrate model organisms, Saccharomyces cerevisiae and Caenorhabditis elegans, was completed. The results (i) quantitatively ...

abstract statement of problem: mechanical strength and durability of dental composites are the main topics studied in this field of science today. this study examined fumed silica-based composite as a strong and durable restorative material through flexural and cycling test methods.     objectives: the purpose of this study was to evaluate the effect of silanization, ageing, cycling and hybridi...

reduced-activation ferritic/martensitic steels have been developed by replacing molybdenum by tungsten and niobium by tantalum in commercial elevated-temperature cr–mo steels to reduce half-life of radioactive isotopes. the objective of this study was to investigate tensile properties of a reduced-activation ferritic/martensitic steel (9cr-2wvta) in normalized-tempered (nt) and quenched-tempere...

Increased life expectancy has led to policy interest in adding quality to years of life and in related concepts such as attitudes to ageing. Improving attitudes to ageing is regarded as one means of improving the participation and contribution of older people within society. In considering agerelated attitudes in the dynamic nature of social identity, age is not just one social category that ma...

BACKGROUND The public health policy agenda oriented towards healthy ageing becomes the highest priority for the European countries. The article discusses the healthy ageing concept and its possible determinants with an aim to identify behavioral patterns related to healthy ageing in selected European countries. METHODS The healthy ageing is assessed based on a composite indicator of self-asse...

The hardness variation and the behaviour of precipitation during the process of three stage ageing of three Al-Cu-Mg alloys were investigated using micro-hardness and differential scanning calorimetry (DSC). To facilitate the determination of the optimised heat treatment condition, a uniform design method was employed by which the influences of three stages interrupted ageing on the hardness an...

OBJECTIVES The aim of the study was to describe the ageing HIV-infected population (> 50 years old) and their current antiretroviral therapy (ART), comorbidities and coprescriptions in France in 2013 and to compare them to the younger population. METHODS A retrospective analysis of a prospectively collected database was performed. The characteristics of patients receiving ART as well as their...
