to aging

تعريف to aging في الإنجليزية الإنجليزية القاموس.: The deliberate act of making something (such as an antique) appear older than it is; Allowing something to become older
The owner asked the clerk to age some big bills that were due.; present participle of age; The process of becoming older or more mature; The change in properties of a material with time under given conditions; A change in the properties of certain metal and alloys (such as steel) that occurs at ambient or moderately elevated temperatures after a hot working heat treatment or cold working operation Typical properties impacted are: hardness, yield strength, tensile strength, ductility, impact value, formability, magnetic properties, etc See also Non-aging; As applies to hams - After curing and salt equalization are completed, hams are hung in an area protected from insects and has good air exchange Temperatures should be 70-90° and humidity at 50- 60% Hams can be aged for 6 months The aging process imparts a flavor due to the enzyme activity in the ham As applies to tenderizing meat - Meat is normally required to age for a period of up to three weeks in order for it to be commercially acceptable for human consumption according to generally accepted standards of tenderness and quality During the aging process, the connective tissues and the meat are generally affected by the natural enzyme or bacteria action of the meat, thereby improving the tenderness and edibility Several methods are employed to reduce the aging period and to increase the degree of tenderness One of these is the regulated application of heat, light, or both of these, to the meat which speeds up the natural enzyme or bacteria action; A term used to describe the holding of meats at a temperature of 34 to 36 degrees F for a period of time to break down the tough connective tissues through the action of enzymes thus increasing tenderness; Irreversible alteration, generally deterioration, of the properties of paper in course of time Aging also causes reduction in brightness and yellowing effect; the decline of the physiological functions which occurs with time, accompanied by a falling probability of survival; (1) (steaming) the curing of screen printed decorations on textiles by application of moist heat to fix the colors into the fibers and to remove the stiffness (hand) induced by normally air dried imprints; (2) the change or changes undergone by a material as a result of the passage of time; The change in properties of a material with time under specific conditions; a change in the properties of certain metals and alloys that occurs at ambient or moderately elevated temperatures after hot working, heat treatment, or a cold working operation; when applied to foods, such as wine, cheese, or beef, aging is the process of allowing a product time to mature Aging allows beef to become more tender and develop fuller flavour Galloway by Choice beef is traditional dry aged for at least three weeks The beef is then cut, cryovac packaged, and shipped Further ‘wet’ aging occurs during distribution and on site storage prior to preparation; the organic process of growing older and showing the effects of increasing age; The separation of invoices, orders, inventory and production lots into time buckets based on due dates, receipt dates, expiration dates, or other factors Used to focus attention on past due and most urgent items; Becoming senescent; accumulating damage to macromolecules, cells, tissues and organs with the passage of time; The change of a material with time under defined conditions, leading to either an improvement or deterioration of properties; see age see ageing. becoming old. ageing the process of getting old. Gradual change in an organism that leads to increased risk of weakness, disease, and death. It takes place in a cell, an organ, or the total organism over the entire adult life span of any living thing. There is a decline in biological functions and in ability to adapt to metabolic stress. Changes in organs include the replacement of functional cardiovascular cells with fibrous tissue. Overall effects of aging include reduced immunity, loss of muscle strength, decline in memory and other aspects of cognition, and loss of colour in the hair and elasticity in the skin. In women, the process accelerates after menopause. See also gerontology and geriatrics; The systematic change in frequency with time due to internal changes in the crystal and/or oscillator Aging is often expressed as a maximum value in parts per million per year [ppm/year] The rate of aging is typically greatest during the first 30 to 60 days after which time the aging rate decreases The following factors effect crystal aging: adsorption and desorption of contamination on the surfaces of the quartz, stress relief of the mounting and bonding structures, material outgassing, and seal integrity; The process of, or the results of, exposure of plastics to natural or artificial environmental conditions for a prolonged period of time; Becoming elderly; {i} maturing; growing older; maturing of financial accounts; growing old; A change in properties of metals and alloys which occurs slowly at room temperature and will proceed rapidly at higher temperatures The change in properties is often, but not always, due to a phase change (precipitation), but never involves a change in chemical composition of the metal or alloy See also Age Hardening See Precipitation Hardening; An increase in the proportion of the population in the older ages May also be measured as an increase in the median age of the population; Changes in properties of rubber occurring with the passage of time Qualification of this term is usually necessary, e g , heat aging, light aging; The physical and/or chemical change of a material with respect to time, under defined environmental conditions, leading to improvement or deterioration of properties; A classification of accounts by the time elapsed since the billing date or due date Aging is divided into schedules or accounting periods, such as 0-30 days, 31-60 days, and so on; acquiring desirable qualities by being left undisturbed for some time; the effect on materials that are exposed to an environment for an interval of time; Changes in physical and mechanical properties that occur when low carbon steel is stored for some time Aging is also accelerated by exposure of steel to elevated temperatures; The systematic change in frequency over time because of internal changes in the oscillator For example, a 100 kHz quartz oscillator may age until its frequency becomes 100 01 kHz (see drift) NOTE: Aging is the frequency change with time when factors external to the oscillator such as environment and power supply are kept constant; The continuous temporal drift in a quartz resonator’s natural frequency due to changes in its chemistry, constituent materials and inadvertent exposure to contaminates during processing Aging is considered the primary end-of -life limit in a quartz controlled frequency source as, at some point in time, the oscillator circuitry can no longer correct the resonator back to its nominal nameplate frequency; The change in the properties of a material over time and under varying conditions of humidity, temperature, pressure, etc; The change in properties or appearance of a material with time and under specific conditions (usually accelerated representations of environmental states, such as high temperature, oxygen or other various conditions or media)
