پس از بررسی هر کدام از فاکتورهای نوع صنعت, نوع ضمانت نامه, نرخ بهره , نرخ تورم, ریسک اعتباری کشورها, کارمزد, ریکاوری, gdp, پوشش و وثیقه بر ریسک اعتباری صندوق ضمانت صادرات ایران مشخص گردید که همه فاکتورها به استثنای ریسک اعتباری کشورها و کارمزد بقیه فاکتورها رابطه معناداری با ریسک اعتباری دارند در ضمن نرخ بهره , نرخ تورم, ریکاوری, و نوع صنعت و ریسک کشورها اثر عکس روی ریسک اعتباری داردو پوشش, وثی...

UV irradiation-induced interleukin-1 and basic fibroblast growth factor synthesis and release mediate part of the UV response.

UV irradiated cells release into the culture medium factors that induce, when given to nonirradiated cells, the transcription of several UV-inducible genes (collagenase I, human immunodeficiency virus type 1, metallothionein IIA). We identify here the active factors released from UV-treated HeLa cells, as interleukin 1 alpha and basic fibroblast growth factor. UV irradiation leads to increased ...

Impact of UV irradiation on multiwall carbon

16 Multiwall carbon nanotubes (MWCNTs) are nanofillers used in consumer and structural 17 polymeric products to enhance a variety of properties. Under weathering, the polymer matrix will 18 degrade and the nanofillers may be released from the products potentially impacting ecological or 19 human health. In this study, we investigated the degradation of a 0.72 % (by mass) 20 MWCNT/amine-cured ep...

Effect of UV irradiation on cut cantaloupe: terpenoids and esters.

Recent studies demonstrated that ultraviolet (UV) radiation enhanced terpenoids and decreased esters in thin-sliced cantaloupe. In preliminary studies treating fresh juices with UV, terpenoid compounds that normally were not isolated, or found in minute quantities, were elevated and only low molecular weight alcohols, ketones, and aldehydes decreased. Subsequently terpenoid induction/oxidation ...
