5. First-Principles Calculations of a New Semi-Conductive Carbon Allotrope Named ABF-Carbon
Carbon is an extremely versatile element and can generate a plethora of structures with distinct properties. Proposing new possible metastable allotropic structures for carbon has been the subject of increasing interest over the past few years. In this contribution, we present a new carbon allotrope, named ABF-Carbon, based on the connection of spiropentadie

7. EVOLUÇÃO DA LEGISLAÇÃO E DAS TÉCNICAS ANALÍTICAS APLICADAS A ESTUDOS DE ESTABILIDADE DE INSUMOS E PRODUTOS FARMACÊUTICOS
Stability is an important parameter to evaluate the quality, safety and efficacy of drug substances and pharmaceutical products. The stability studies aim to determine the ability of a formulation to maintain its specifications, in order to establish shelf life and recommended storage conditions. Despite the extensive relevance, until the 1980’s the stabil

9. The population dynamics of three polyphagous owlet moths (Lepidoptera: Noctuidae) and the influence of meteorological factors and ENSO on them
ABSTRACT The owlet moths (Lepidoptera: Noctuidae) Anicla infecta (Ochsenheimer 1816), Elaphria agrotina (Guenée 1852) and Spodoptera frugiperda (J.E. Smith 1797) occur in the entire American continent. These polyphagous moths have a preference for grasses, and have different biological habits. In this study, the populations of these three species were evalu
