1. Originally a process in which printed fabric was exposed to a hot moist atmosphere. At the present time, the term is almost exclusively applied to the treatment of printed fabric in moist steam in the absence of air. Ageing is also used in the development of certain colorants, e.g., aniline black. 2. In the manufacture of viscose, the oxidative depolymerization of alkali cellulose in order to produce a controlled decrease in the chain length of the cellulose. The term is sometimes, although incorrectly, used to describe the ripening of viscose (see ripening 2). 3. The oxidation by exposure to air of drying-oil sizes and finishes, e.g., in the production of oiled silk and oilskins and in linseed oil sizing. 4. The deterioration of rubber and plastic coatings and proofing and of some lubricants on textiles, caused by gradual oxidation on storage and/or exposure to light. 5. Progressive change with time in the structure and properties of polymers, including wool fibres.
The decline in organismal fitness that occurs with increasing age.
The deterioration of paper properties with time. Sunlight and heat accelerate loss of strength and brightness.
Physical Properties and Testing Deterioration of a material over time on exposure to adverse environmental conditions (e.g. elevated temperature, UV light, ozone).
The lenghth of time a wine should age depends on the type grape and the type of wine being produced and can vary from a few weeks to many decades. Ageing in barrels provides a slow oxidation while simultaniously inparting the flavours of the wood on the wine. Bottle ageing allows the wines to soften and various components within the wine to harmonize. Eventually bottled wines will begin to deminish in quality if allowed to hang around too long.
Process through which wines are aged and mature, whether in the bottle or in oak casks.
the organic process of growing older and showing the effects of increasing age
The process where a whisky spends time in oak barrels to develop its individual character. The ageing process ends once the whisky is bottled, regardless of the length of time it spends in the bottle.
(Australian/British spelling) Aging (American spelling). It is important to incorporate the two spellings in computer searches.
Natural ageing as a cause of disability for adults. This option was recorded as a cause of disability only if other disability causes were not specified. It was not read out by interviewers.
A change in properties that may occur gradually at atmospheric temperatures (natural ageing) and more rapidly at higher at higher temperatures (artificial ageing).
The changing of a material with time under defined environmental conditions, leading to improvement or deterioration of properties. Addition of Antioxidants, UV / Light stabilizers, and so on, allows an improvement of ageing properties.
Ageing or maturation – a process to which most wines are submitted – takes place from the time of fermentation, either in a barrel or tank, or in the bottle.
All wine is aged, from a few weeks to many decades. Ageing in barrels is a very slow oxidation, and the barrels can impart flavours to the wine: bottle ageing allows the wines to soften and various components within the wine to harmonize. After a certain point all wine will decline in the bottle.
The ageing process is characterised by the acquisition of progressive multiple minor impairments predominantly related to sight, hearing, dexterity, mobility and cognition. In combination these can lead to high levels of disability and dependency.
Whiskey ages in oak casks; once it is bottled no further ageing takes place.
Whisky gets its individual character by maturing within the confines of a cask and once bottled the ageing process ends.
Whisky is aged (matured) in oak casks: once it is bottled no further ageing takes place.
Ageing or aging is the process of becoming older. This traditional definition was recently challenged in the new "Handbook of the Biology of Aging" (Academic Press, 2006), where ageing was specifically defined as the process of system's deterioration with time, thus allowing for existence of non-ageing systems (when "old is as good as new"), and anti-ageing interventions (when accumulated damage is repaired). This article focuses on the social, cognitive, cultural, and economic effects of ageing.
