Ultraviolet concentration factor of a truncated compound parabolic concentrator under different weather conditions
(Pleiades PublishingRU, 2020)
This study presents the results of ultraviolet radiation measurement in a truncated compound parabolic concentrator. The measurements were performed by using of a portable ultraviolet sensor both inside and outside the ...
Transcriptome changes in grapevine (Vitis viniferaL.) cv. Malbec leaves induced by ultraviolet-B radiation
(2010-10)
Ultraviolet-B radiation (UV-B, 280-315 nm) is a natural component of sunlight, which has numerous regulatory effects on plant physiology. The nature of the response to UV-B is dependent on fluence rate, dose, duration and ...
Effects of ultraviolet radiation on the microbiological, physicochemical, and sensory properties of Rangpur lime juice
(Universiti Putra Malaysia. Faculty of Food Science and Technology, 2018-10)
Rangpur lime juice was subjected to ultraviolet (UV) radiation as a non-thermal technology and changes in/on quality characteristics (microbiological, physicochemical and sensorial) were determined in order to extend its ...
Sublethal effects of ultraviolet radiation on crab larvae of Cyrtograpsus altimanus
(Elsevier Science, 2011-10)
Ultraviolet radiation (UVR, 280-400. nm) is known to be lethal to several aquatic species; however, more subtle, 'sublethal' effects of UVR have recently received more attention. Larvae of the crab Cyrtograpsus altimanus ...
Wavelength-dependent xanthophyll cycle activity in marine microalgae exposed to natural ultraviolet radiation
(Taylor & Francis Ltd, 2009-11)
The wavelength dependency of xanthophyll cycling in two marine microalgae (Thalassiosira weissflogii and Dunaliella tertiolecta) was studied by establishing biological weighting functions (BWFs) during exposure to natural ...
Solar UV-B radiation modifies the proportion of volatile organic compounds in flowers of field-grown grapevine (Vitis vinifera L.) cv. Malbec
(2014-11)
Ultraviolet-B solar radiation (UV-B) is an environmental signal with biological effects in different plant tissues. Recent investigations reported dramatic changes of terpenes with a protective role in plant tissues submitted ...
Volatile organic compounds characterized from grapevine (Vitis vinifera L. cv. Malbec) berries increase at pre-harvest and in response to UV-B radiation
(2013-12)
Ultraviolet-B solar radiation (UV-B) is an environmental signal with biological effects in plant tissues. Recent investigations have assigned a protective role of volatile organic compounds (VOCs) in plant tissues submitted ...
