EFFECT OF ULTRAVIOLET ON OUTDOOR WORKERS

open access: yesJournal of Engineering and Sustainable Development, 2022
The sunlight mainly affected the development of this life on the surface of the globe, most people love and enjoy the sunlight and its warmth, but fear its harmful effects from sunburn and long-term damage to the skin due to excessive exposure to the sun,

Changes in Ultraviolet Absorption of Sunscreens After Ultraviolet Irradiation [PDF]

open access: yesJournal of Investigative Dermatology, 1999
The incidence of skin cancer is increasing rapidly and sunscreens have been recommended in order to reduce damage from sunlight. In this investigation we have studied the change in the absorption spectrum of some photoactive organic species in sunscreens after ultraviolet A and ultraviolet B irradiation in a dose normally encountered during a full day ...

Combined Effects of UVR and Temperature on the Survival of Crab Larvae (Zoea I) from Patagonia: The Role of UV-Absorbing Compounds

open access: yesMarine Drugs, 2010
The aim of our study was to assess the combined impact of UVR (280–400 nm) and temperature on the first larval stage (Zoea I) of three crab species from the Patagonian coast: Cyrtograpsus altimanus, C. angulatus,and Leucippa pentagona.

Laser-stimulated fluorescence reveals unseen details in fossils from the Upper Jurassic Solnhofen Limestones

open access: yesRoyal Society Open Science, 2021
Laser-stimulated fluorescence (LSF) has seen increased use in palaeontological investigations in recent years. The method uses the high flux of laser light of visible wavelengths to reveal details sometimes missed by traditional long-wave ultraviolet (UV)

Ultraviolet-Protected Inflation [PDF]

open access: yesPhysical Review Letters, 2011
In natural inflation, the inflaton is a pseudo-Nambu-Goldstone boson which acquires a mass by explicit breaking of a global shift symmetry at scale f. In this case, for small field values, the potential is flat and stable under radiative corrections.

Targeting the Next Generation of Deep-Ultraviolet Nonlinear Optical Materials: Expanding from Borates to Borate Fluorides to Fluorooxoborates.

open access: yesAccounts of Chemical Research, 2019
Coherent light radiation down to the deep-ultraviolet spectral range (λ < 200 nm) produced by common laser sources is extensively used in diverse fields ranging from ultrahigh-resolution photolithography to photochemical synthesis to high-precision ...

Solar-blind ultraviolet-C persistent luminescence phosphors

open access: yesNature Communications, 2020
Visible-light and infrared-light persistent phosphors are extensively studied and are being used as self-sustained glowing tags in darkness. In contrast, persistent phosphors for higher-energy, solar-blind ultraviolet-C wavelengths (200–280 nm) are ...

La Tecnologia Beacon al Servizio del Patrimonio Culturale. Il caso dei Musei di Palazzo Farnese e della città di Piacenza

open access: yesArcheomatica, 2015
The Civic Museums of Palazzo Farnese in Piacenza are the first Italian museum and one of the first five in Europe to achieve an application based on advanced technologies related to proximity (beacon) and one of the first in the world to adapt it on ...
