1. 2D, 3D and Hybrid QSAR Studies of Nostoclide Analogues as Inhibitors of the Photosystem II
Synthetic herbicides are widely used for weed control in crops. Continuous application of chemicals induces the adaptation of weeds, leading to the development of resistance. Therefore, research for novel synthetic herbicides plays an important role in crop protection and food production. Within this context, it is important to understand the relationship be

3. HYDROGEN PRODUCTION AND PERFORMANCE OF ANAEROBIC FIXED-BED REACTORS USING THREE SUPPORT ARRANGEMENTS FROM CASSAVA STARCH WASTEWATER
ABSTRACT Fixed-bed reactors have been considered promise alternatives for hydrogen production due to their simple construction and increase in the biomass retention. The purpose of this study was to investigate the biological production of hydrogen in anaerobic fixed-bed reactors with cassava starch wastewater used as substrate. Different support materials a

4. Fermentative hydrogen production from agroindustrial lignocellulosic substrates
To achieve economically competitive biological hydrogen production, it is crucial to consider inexpensive materials such as lignocellulosic substrate residues derived from agroindustrial activities. It is possible to use (1) lignocellulosic materials without any type of pretreatment, (2) lignocellulosic materials after a pretreatment step, and (3) lignocellu

5. Immobilized Biofilm in Thermophilic Biohydrogen Production using Synthetic versus Biological Materials
Biohydrogen production was studied from the vermicelli processing wastewater using synthetic and biological materials as immobilizing substrate employing a mixed culture in a batch reactor operated at the initial pH 6.0 and thermophilic condition (55 ± 1ºC). Maximum cumulative hydrogen production (1,210 mL H2/L wastewater) was observed at 5% (v/v) addition

6. Biohydrogen production from cassava wastewater in an anaerobic fluidized bed reactor
The effect of hydraulic retention time (HRT) and organic loading rate (OLR) on biological hydrogen production was assessed using an anaerobic fluidized bed reactor fed with cassava wastewater. The HRT of this reactor ranged from 8 to 1 h (28 to 161 kg COD/m³-d). The inoculum was obtained from a facultative pond sludge derived from swine wastewater treatment

7. Produção de hidrogênio via fermentação anaeróbia - aspectos gerais e possibilidade de utilização de resíduos agroindustriais brasileiros
Biological production of hydrogen through anaerobic fermentation has received increasing attention and offers a great potential as an alternative process for clean fuel production in the future. Considering biological systems for H2 production, anaerobic fermentation stands out, primarily due to its higher production of H2 compared with other biological proc

8. Atividade imunoestimulante e anti-Leishmania de Chenopodium ambrosioides L. (mastruz). / And immunostimulatory activity of anti-Leishmania Chenopodium ambrosioides L. (mastruz).
Chenopodium ambrosioides a plant species popularly knows as mastruz, mastruço, menstruço or erva de Santa-Maria have been used to treat leishmaniasis in endemic areas of the Northestern of Brazil. The aim of this work was to evaluate the immunomodulatory and antileishmania effects of this plant. In order to investigate the effect on macrophage activity and

9. Análise estrutural do domínio de reconhecimento a carboidratos da lectina Dvirl de Dioclea virgata e sua correlação na indução da produção de óxido nítrico / Structural analysis of the carbohydrate recognition domain the DvirL lectin from Dioclea virgata and its correlation in the induction of nitric oxide production
Lectins are defined as proteins or glycoproteins of nonimmune origin that have at least one site of reversible binding to carbohydrates or glycoconjugates. Lectins of plant origin are the most studied and characterized as three-dimensional structure and biological functions related. Lectins can be found in different parts of the plant from its root to the in

10. Fenil éster do ácido caféico melhora a resposta ao estresse oxidativo em modelo animal de obesidade induzida por dieta hiperlipídica / Caffeic acid of phenethyl ester improves the oxidative stress response in animal model of obesity induced by high fat diet
Obesity is a disease that is increasing in a drastically way around the world and is implicated in many pathological conditions, such as insulin resistance, type 2 diabetes, dyslipidemia, fatty liver disease, hypertension and cardiovascular risk. Evidence has shown that obesity is a chronic oxidative stress state that is associated with metabolic and physiol

12. Effect of hydrogen peroxide and chlorite ion residual on an activated sludge system of bleached kraft pulp mills / Efeito do residual de peróxido de hidrogênio e do íon clorito em um sistema de lodos ativados de indústrias de celulose kraft branqueada
Hydrogen peroxide and chlorine dioxide has been largelly used in bleaching plants of bleached kraft pulp mills, to delignify and to whiten the pulp, giving to it high quality, specially brightness. However, in some transient situations, such changes in the raw material, in the bleaching sequences, or in production, high charges of oxidants are required to ma
