1. COMPLEXO ESTUARINO LAGUNAR MUNDAÚ-MANGUABA: CARACTERIZAÇÃO DA MATÉRIA ORGÂNICA NATURAL E INTERAÇÃO COM ÍONS Hg2+
The Mundaú-Manguaba lagoon estuary complex is the most important ecosystem in the state of Alagoas, and a source of sustenance for a large number of the state’s inhabitants. However, degradation by anthropic sources has been causing impacts on this ecosystem. Understanding the characteristics of the natural organic material of the waters of the mundaú-ma

2. Síntese e caracterização de novos polímeros líquido-cristalinos de cadeia lateral derivados do heterociclo 2-isoxazolínico 3,5-dissubstituído
This thesis presents the synthesis and characterization of new polymer liquid crystal materials based on heterocycle 2-isoxazoline 3,5-disubstituted. We studied the inversion effects of groups linked in position 3 and 5 in 2-isoxazoline in the mesogenic group attached by side chain polymer liquid crystal and the influence in liquid crystals properties. The m

3. Contribuição ao estudo químico e avaliação da atividade antioxidante dos frutos verdes de Clusia paralicola (Clusiaceae)
Clusia paralicola (Clusiaceae) occurrs in forests from northeastern Brazil, especially in the semi-arid and wet forests, is popularly known as pororoca. This work describes the chemical and antioxidant activity of the green fruits from Clusia paralicola G. Mariz Cunha and resulted in the isolation and identification of two biflavonoids (GB1-7"-Oglucoside and

5. Diversidade e biogeografia de fungos no solo sob a projeção da copa de espécies arbóreas da Mata Atlântica / Diversity and biogeography of fungi in soil under the canopy of tree species in the Atlantic Forest
The community structure and diversity of fungi in soil under the canopy of four tree species (Ocotea dispersa, Ocotea teleiandra, Tabebuia serratifolia, and Mollinedia schottiana), in the Carlos Botelho State Park (PECB) were examined in two different seasons, using PCR-DGGE and rDNA ITS region clone library sequencing. The relationships between fungal commu

6. Modelagem molecular aplicada ao estudo de reações de inibição enzimática com aplicação potencial no controle de Leishmania amazonensis. 2010. / Applied molecular modeling to the enzymatic inhibition reactions study with Leishmania amazonensis controls potential application. 2010.
Parasitic protozoan diseases, transmitted by blood-feeding insects, constitute the worlds most widely spread human health problem. It is estimated that three million people suffer from a parasitic infection (mainly trypanosomatid and apicomplexan parasites), responsible for important human diseases. The compounds here studied constitute the amidines and the

7. Estruturas das comunidades e caracterizações metabólicas de leveduras em solos de Terra Preta Antropogênica / The communities structures and metabolic characterizations of yeasts in Anthropogenic Dark Earth soils
A Terra Preta Antropogênica (TPA) é considerada um dos solos mais férteis do mundo, constituída de pequenas faixas e distribuídos aleatoriamente pela região Amazônica. Sua denominação é decorrente da presença de grupos pré-históricos que viveram nestes sítios arqueológicos ao longo dos rios da Amazônia, principalmente Central e Oriental. A gr

9. Peptídeos antimicrobianos: síntese, ensaios biológicos, estudos termodinâmicos e análise estrutural por RMN em meios biomiméticos
Many organisms employ noxious chemicals (e.g., amines, steroid derivatives, alkaloids and peptides) to defend themselves against predators and pathogenic microrganisms. Among these chemical agents stand out peptides that can be found in a wide variety of organisms including bacteria, fungi, plants, insects, fish, amphibians,arachnids and mammals. The vast ma
