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.

Vogel, Saxon, Zach Hamilton and Hannah were all added as major fixtures during the show's end times, and I feel like I barely got to know them before I was supposed to care about their deaths. I actually wound up setting a fantasy football lineup during Vogel's death scene, and while Hannah was interesting last year, she's been kind of lost in the shuffle this season and somewhat devoid of purpose. I understand she's the vehicle helping free Dex of his dark passenger, but their reconciliation didn't feel earned. Sure, I believe they need each other and would have found their way back into one another's arms eventually, but they brushed off the whole Hannah trying to murder Deb/Dexter sending Hannah to prison thing far too easily.

Without FDI, which is spent on actual projects (as opposed to shares) and thus more difficult to withdraw, every dollar that foreign mutual funds pull out of the market increases India's current account deficit (the shortfall of money flowing in versus out of the country). That in turn causes the rupee to drop in value. And that drop in value results in currency losses that encourage foreign investors to pull even more money out of the market.
