Cell damage repair mechanism in a desert green algae Chlorella sp. against UV-B radiation

open access: yesEcotoxicology and Environmental Safety, 2022
The protective ozone layer is continually depleting owing to an increase in the levels of solar UV-B radiation, which has harmful effects on organisms.

シガイセン ゾウカ ガ ショクブツ ニ オヨボス エイキョウ [PDF]

open access: yes, 2010
Ultraviolet-B (UV-B) radiation is increasing in the result of stratospheric ozone depletion and other unknown factors. It has been supposed that increase in UV-B radiation will cause the various detrimental effects on plants.

LIGHT CONVERSION AND SCATTERING IN UV PROTECTIVE TEXTILES [PDF]

open access: yes, 2014
The primary cause of skin cancer is believed to be a long exposure to solar ultraviolet radiation (UV-R) crossed with the amount of skin pigmentation in the population. It is believed that in childhood and adolescence 80% of UV-R gets absorbed, whilst in

Adjustment of Coatings Morphology and Particle Distribution of Layered Silicates by Freeze‐Drying for Improved Gas Barriers

open access: yesAdvanced Engineering Materials, EarlyView.
Freeze‐drying of layered silicate is the key to get coatings with superior gas barrier. Freeze‐drying of layered silicates modified with dodecylamine (DDA) is a highly effective technique for the preparation of barrier pigments that significantly mitigate the permeation of oxygen, water vapor, and hydrogen through polymer films containing these ...

UV PROTECTION WITH ZEOLITE TREATED COTTON KNITTED FABRIC - THE INFLUENCE OF YARN LINEAR DENSITY [PDF]

open access: yes, 2007
UV radiation (UV-R) can be divided into UV-A, UV-B and UV-C radiation. UV-C radiation get absorbed by atmosphere, but diminishing of the ozone layer results with the reaching of UV-B and UV-A rays on the Earths surface.

Regulation of UVR8 photoreceptor dimer/monomer photo-equilibrium in Arabidopsis plants grown under photoperiodic conditions [PDF]

open access: yes, 2016
The UV RESISTANCE LOCUS 8 (UVR8) photoreceptor specifically mediates photomorphogenic responses to UV-B. Photoreception induces dissociation of dimeric UVR8 into monomers to initiate responses.

Trace Nickel Activated Biphasic Core‐CuOii/Shell‐CuOi Secondary Microspheres Enable Room Temperature Parts‐Per‐Trillion‐Level NO2 Detection

open access: yesAdvanced Engineering Materials, EarlyView.
An idea of designing novel sensors is proposed by creating appropriate Schottky barriers and vacancies between isomorphous Core‐CuOii/ Shell‐CuOi secondary microspheres and enhancing catalytic and spill‐over effects, and electronegativity via spontaneous biphasic separation, self‐assembly, and trace‐Ni‐doping.

Hormonal regulation of crop adaptation to UV-B radiation stress: implications for UV-B-Resistant crop varieties and sustainable agriculture

open access: yesDiscover Agriculture
Ultraviolet-B (UV-B: 280–315 nm) radiation stress severely compromises crop quality and productivity, necessitating the development of effective adaptive mechanisms. For plants to coordinate these adaptive responses, hormonal control is crucial. However,

Cadmium telluride quantum dots (CdTe-QDs) and enhanced ultraviolet-B (UV-B) radiation trigger antioxidant enzyme metabolism and programmed cell death in wheat seedlings.

open access: yesPLoS ONE, 2014
Nanoparticles (NPs) are becoming increasingly widespread in the environment. Free cadmium ions released from commonly used NPs under ultraviolet-B (UV-B) radiation are potentially toxic to living organisms. With increasing levels of UV-B radiation at the

Impact of elevated carbon dioxide concentration on protein content of gliadin fraction in winter wheat [PDF]

open access: yes, 2016
Cílem této bakalářské práce bylo studium vlivu zvýšené koncentrace CO2, dusíkatého hnojení a UV záření na obsah gliadinové frakce u ozimé pšenice. Ozimá pšenice (Triticum aestivum) odrůdy Bohemia byla pěstována v podmínkách normální a zvýšené koncentrace
