1. Post-fire regeneration in seasonally dry tropical forest fragments in southeastern Brazil
ABSTRACT Seasonally dry tropical forest is one of the highly threatened biome. However, studies on the effect of fire on these tree communities are still scarce. In this context, a floristic and structural survey in three forest areas in the southeast of Brazil that were affected by fire between 14 and 25 years ago was performed with the objective of evaluat

2. Study of bond behavior between reinforced bar and concrete with epoxi resin. / Estudo da aderência de barras de aço coladas ao concreto com resina Epóxi.
Just like others fields of knowledge, the civil construction is evolving. Hughes investments and the need for new projects improve the speed and the technology usually applied for basic infrastructures development. These scenarios achieve issues as the miss understanding of the behavior of this technological advances in long terms, caused by the few studies

3. Development of immunoassay techniques to detect microcystin in environmental samples / Desenvolvimento de técnicas de imunoensaio para detecção de microcistina em amostras ambientais
The contamination of drinking water by cyanobacterial toxins is a public health issue and a concern for water authorities throughout the world. Microcystin-LR (MCLR) is a hazardous cyclic heptapeptide cyanotoxin, which inhibits protein phosphatase PP1 and PP2A in hepatocytes. Microcystins are produced by several genera of cyanobacteria and presents more than

4. Estudo da labilidade de Cu(II), Cd(II), Mn(II) e Ni(II) em substâncias húmicas aquáticas utilizando-se membranas celulósicas organomodificadas
In this work commercial filters papers were organomodified with tetraethylorthosilicate (TEOS) and 3-aminopropyltriethoxysilane (3-APTS), aiming at the development of a new analytical procedure for in-situ speciation of labile and inert metal species in aquatic systems. Parameters that exert influence on the metal lability such as pH, chelating time, concent

5. AVALIAÇÃO DA INTEGRIDADE ESTRUTURAL DE PONTES METÁLICAS DA FERROVIA TURÍSTICA OURO PRETO/MARIANA (MG) POR MEIO DE MODELAGEM NUMÉRICA E TÉCNICAS LABORATORIAIS
With the recuperation of the national railroad system in mind, a study of the pathological phenomena that occur in metallic railroad bridges was performed. These phenomena, such as: corrosion, fatigue cracks, loose connections and deformation and/or excessive displacement of the structural elements, are the principal factors responsible for bridge interventi

6. SimulaÃÃo numÃrica do comportamento mecÃnico de elementos de concreto armado afetados pela reaÃÃo Ãlcali-agregado / Numerical simulation of the mechanical behaviour of reinforced concrete members affected by alcaliaggregate reaction
The subject of this work is the numerical simulation of the swelling due to alkaliaggregate reaction in reinforced concrete members. The inert chemically nature of the aggregate of cement Portland concrete was early questioned by Stanton (1940), nevertheless, just awaked Civil Engineering community interest, in 1980âs decade, because its damage in concrete

7. Teachers Manifestations about the organization of the educative work to attend students who finish fundamental education in legality of the cycle regime and the continued progression / Manifestações de professores sobre a organização do trabalho educativo para atender os estudantes que terminam o ensino fundamental na vigência dos ciclos e da progressão continuada
The central problematic of this research refers to the way in which 8th grade teachers in São Paulo state net with more than 10 years of classroom experience manifested themselves about the organization, in their daily activity, to attend what is foreseen to implement the cycle regime and the continued progression. My study searched and analyzed whatever th
