3. Photolytic degradation of chloramphenicol in different aqueous matrices using artificial and solar radiation: reaction kinetics and initial transformation products
A fotodegradação de cloranfenicol (CAP) em água ultrapura (UW), água superficial não tratada (USW), e efluente tratado de estação de tratamento de esgoto (TESTP) em escala de laboratório e planta piloto, foi avaliada usando radiação artificial e solar. Os resultados mostram, em todos os casos, que a degradação de CAP ocorre segundo uma cinética

4. Iluminación natural en aulas: análisis predictivo dinámico del rendimiento lumínico-energético en clima soleados
In towns like Mendoza (Argentina), where sunny, clear skies predominate, solar radiation provides high values of luminous efficacy. This allows minimizing, and sometimes eliminating, the consumption of electricity in indoor spaces during daylight hours. The goal of this study is to analyze and compare the autonomy of daylight and electricity consumption in c

7. Avaliação da fototoxicidade do antraceno sobre a mortalidade e o dano ao DNA de juvenis de pampos, Trachinotus carolinus (Linnaeus, 1766) / Assessment of the effect of the phototoxicity of anthracene on the mortality and damage to the DNA of juveniles of Florida pompanos, Trachinotus carolus
Polycyclic aromatic hydrocarbons are toxic and/or genotoxic to a variety of marine organisms and under solar or artificial ultraviolet radiation acute toxicity of many of them can be substantially enhanced. The aim of the present study was to examine the effect of the phototoxicity of anthracene on the mortality and damage to the DNA, assessed by the comet a

12. Geomagnetic DST index forecast using artificial neural networks and decision tree / Previsão do índice geomagnético dst utilizando redes neurais artificiais e árvore de decisão
The Earth suffers constant influence of the solar activity through the solar wind, which brings with it the resulting structures, mainly phenomena like solar flares and coronal mass ejection. The almost static interaction between the solar wind and the geomagnetic field forms a structure called magnetosphere, which acts as a shield that protects the planet f
