Decolorization Kinetics of Ponceau S Dye by Chemical Chlorination: A Comparison with Sunlight/ Chlorine and UV/Chlorine Processes [PDF]
Aqueous chlorination of Ponceau S dye (PS) was kinetically investigated through a classical method and under solar or UV radiations. For the classical method, the kinetics of PS chlorination was established by varying concentration ratios R = [Free ...

Excimer UV Radiation in Dermatology
Ultraviolet B (UVB 290–320 nm) radiation has been used in the treatment of different skin diseases. Light sources with narrowband UVB output spectrum have been developed with the aim of increasing the rates of “beneficial to side effect” profile of the treatment.

Harmonic generation and filamentation: when secondary radiations have primary consequences
In this Letter, it is experimentally and theoretically shown that weak odd harmonics generated during the propagation of an infrared ultrashort ultra-intense pulse unexpectedly modify the nonlinear properties of the medium and lead to a strong ...

CONSIDERATIONS CONCERNING THE INFLUENCE OF UV RADIATIONS ON THE BODY [PDF]
This paper shows how the association between ultraviolet light (UV) and the diseases produced by the human body. There is strong evidence that exposure to ultraviolet radiation (UVR) is associated with malignancy of basal cell carcinoma, photokeratitis ...

Generalized Vaidya Solutions and Misner-Sharp mass for $n$-dimensional massive gravity [PDF]
Dynamical solutions are always of interest to people in gravity theories. We derive a series of generalized Vaidya solutions in the $n$-dimensional de Rham-Gabadadze-Tolley (dRGT) massive gravity with a singular reference metric.
