Evaluation of ultraviolet radiation in the sterilization of plastic packaging
(Univ Federal Lavras-uflaLavrasBrasil, 2008)
Influence of the degradation on the stress cracking values of high density polyethylene (HDPE) geomembranes after different exposures
(2012-12-03)
This paper presents results from stress cracking (SC) tests performed in both fresh and exposed high density polyethylene (HDPE) geomembranes (GM). The HDPE GMs were exposed to ultraviolet radiation, thermal aging (air ...
Update On Ultraviolet A And B Radiation Generated By The Sun And Artificial Lamps And Their Effects On Skin
(WILEY-BLACKWELLHOBOKEN, 2015)
UV-B radiation reduces biocontrol ability of Clonostachys rosea against Botrytis cinerea
(Taylor & Francis Ltd, 2016-01-01)
There is a lack of information comparing UV-B radiation conidial sensitivity of the biocontrol agent Clonostachys rosea (Cr) and its target pathogen, Botrytis cinerea (Bc). We investigated the interactions in vitro and on ...
UVER and UV index at high altitude in Northwestern Argentina
(Elsevier Science Sa, 2016-10)
Measurements of ultraviolet erythemal radiation (UVER) made during two years at three sites located at altitudes over 1000 m a.s.l. in Northwestern Argentina (Salta, San Carlos, and El Rosal) have been used to estimate and ...
Influence of photodegradation with UV radiation in biotreatment with Paecilomyces variotti on PHBV/GNS nanocomposites
(Inst Engineering Technology-iet, 2018-04-01)
Graphite nanosheets (GNSs) and poly(hydroxybutyrate-co-hydroxyvalerate) (PHBV) nanocomposites were prepared by solution casting method. This study aimed to evaluate the effects of previously phototreatment with ultraviolet ...
Proteção à radiação ultravioleta: recursos disponíveis na atualidade em fotoproteção
(Sociedade Brasileira de Dermatologia, 2011)
A radiação ultravioleta pode provocar danos ao DNA, imunossupressão, alterações químicas e histológicas na epiderme, envelhecimento precoce, cataratas e carcinogênese, dentre outras deteriorações. A fotoproteção previne ...
Photosensitivity of Cucumber (Cucumis sativus L.) Seedlings Exposed to Ultraviolet-B Radiation
