1. Upgrade of Biofuels Obtained from Waste Fish Oil Pyrolysis by Reactive Distillation
Bio-oil is classified as second-generation biofuel and it is produced mainly through the pyrolysis of a waste lignocellulosic biomass base. The application of this product is still very limited, due to some of its chemical characteristics. This paper presents a proposal for the reduction of the acidity of bio-oil obtained from waste fish oil, previously prod

2. Uma abordagem neurofisiológica da acetilcolina em plantas de milho hidratadas e sob condições de estresse hídrico / A neurophysiological approach to acetylcholine in maize plants hydrated and under water stress conditions
The occurrence of action potential and neurotransmitters, the major components of animal nervous system, in plants, bacteria and fungi, shows the universality of signaling principles and information transmission in the way of chemical and electrical signals in all organisms. These study topics, along with plant intelligence and vesicular-based auxin transpor

3. The role of fine particulate matter composition of PM2,5 and ROFA in the cell mutagenic potential and toxicity: a vegetable and animal bioassay study / Efeito da composição do material particulado fino, PM2,5 e residual oil fly ash (ROFA), como determinante do potencial mutagênico e tóxico celular: um estudo em bioensaios vegetais e animais
The association between atmospheric particulate matter (PM) and adverse human health effects have been consistently reported in epidemiological and experimental studies however, the ability to define the most important components involved in PM toxicity is hindered by its complex composition. In the present study we decided to further explore the effects of

4. ADSORÇÃO DE UM ÁCIDO GRAXO UTILIZADO EM FLOTAÇÃO POR VERMICULITA HIDROFÓBICA
In this work are presented studies to evaluate the adsorption capacity of the expanded vermiculite mineral and of the vermiculite hydrophobized mineral originating from the states of Piauí and Goiás with different size. Tests of adsorption were accomplished in direct contact systems with oil, contact with solution oil-water that simulates oil spilling in t

5. "Síntese e caracterização espectroscópica de materiais orgânicos para eletrônica molecular" / "Synthesis and spectroscopic characterization of the organic materials for molecular electronic"
This work was separated in two parts, in the first, called PART A, the synthesis of the polymers PPV, Cl-PPV, Br-PPV and of the co-polymers (Cl-PPV)m / (PPV)n and (Br-PPV)m / (PPV)n in the following relationships m:n of 30:70; 50:50 and 70:30 are presented. These polymers were characterized by infrared spectroscopy, UVvisible and fluorescence emission. The m

6. Derivatization of urinary benzolecgonine with diazomethane to verify cocaine exposure using chromatographic techniques / Derivação de benzoilecgonina urinária com diazometano para verificação da exposição à cocaína por técnicas cromatográficas
Cocaine abuse is now representing one of the greatest world public health problem. Great social interests have been generated with the using of toxicological analyses with the aim of detecting cocaine exposure to adopt prevention and control measures. Benzoylecgonine, the main metabolite found in urine, is one of the biological markers of cocaine exposure. H
