پیرشدگی تسریع یافته

آزمایش پیرشدگی تسریع یافته (پیرسازی) یا فرسودگی ( Accelerated Aging ) ، آزمایشی است که شرایط تشدید شده ی گرما ، رطوبت ، اکسیژن ، نور خورشید ، لرزش و غیره را به منظور پیرسازی یا همان سرعت بخشیدن به پروسه افزایش سن مواد غذایی به کار می گیرد .
این آزمایش به منظور آشکار سازی اثرات مراحل مختلف اعمال تنش در یک دوره ی کوتاه استفاده می شود ، اعمال تنش در آزمایشگاه و بوسیله دستگاه های چمبر تست محیطی مخصوص تحت متد های کنترل شده و استاندارد صورت می گیرد .
این آزمایش برای تخمین طول عمر قابل استفاده یک محصول مصرفی (عمر مفید) یا به عبارت دیگر برای پیدا کردن تاریخ انقضا مواد مصرفی نظیر مواد غذایی و داروها به کار گرفته می شود.
از پیرشدگی تسریع یافته هنگامی استفاده می شود که به داده های مربوط به طول عمر واقعی آن محصول غذایی دسترسی وجود نداشته نباشد . با به کارگیری پیرشدگی تسریع یافته محصول مورد آزمایش به اصطلاح دچار پیرشدگی زودرس می شود یا به عبارت دیگر اثرات گذر زمان طولانی، در یک بازه زمانی کوتاهتر بر روی محصول آشکار می گردد. به عنوان مثال یک کنسرو تن ماهی دارای مدت زمان مصرف دو سال پس از تولید است، طبیعی است که تولید کنندگان کنسرو تن ماهی نیز برای تعیین تاریخ انقضای محصول شان واقعا دو سال صبر نکرده اند، آنها نیز طبیعتا با به کارگیری پیرشدگی مصنوعی و تشدید شرایط محیطی نگه داری تن ماهی، در بازه زمانی کوتاهتری نسبت به دو سال (فرضا دو ماه) واکنش ها و عوارضی که برای تن ماهی در دوسال بوجود می آمده را شبیه سازی نموده اند تا طول عمر مفید تن ماهی را اندازه گیری نمایند.

 

شرکت آریا سرمایش پردیسان با توجه به نیاز صنایع تولید محصولات فاسد شدنی و آزمایشگاه ها اقدام به ارائه چمبر های مخصوص پیرشدگی تسریع یافته مواد مصرفی و فاسد شدنی کرده است که با اعمال شرایط محیطی تشدید شده نظیر رطوبت های بالا و همچنین دما های مثبت و منفی از منفی هشتاد درجه تا مثبت صد و هشتاد درجه و همچنین اکسیژن، نور خورشید (اشعه UV) و لرزش پروسه پیرسازی مواد غذایی را طبق استانداردهای این حوزه اجرا می کند.

    “Leaders in Misrata watched these developments warily but made a cynical calculation,” described a fascinating piece of research by Brian McQuinn, a former conflict analyst who spent the better part of a year on the ground in Misrata researching the evolution of armed groups for his doctoral thesis in anthropology at Oxford University. The damage that Misratan militias in Tripoli were doing to both their city’s reputation and security in the capital was overshadowed by the strategic value of having proxies — like Swehli’s forces — to maintain their influence over the post-war transition.

    There are two possible wildcards. One, President Obama taps someone to replace outgoing Fed chief Ben Bernanke who's not currently a member of the Fed's voting committee and who has different views on winding down QE. Two, if the Fed this week makes a change to its guidance. If the Fed, which now says it will end QE when the unemployment rate is around 7% and won't start raising short-term rates until the jobless rate is at least 6.5%, lowers those thresholds, it could boost markets as it would suggest the Fed's easy-money policies will be in force longer.
