1. Avaliação de estruturas de edifícios em concreto armado com vistas à reabilitação / Evaluation of building structures in concrete with a view to rehabilitation
With the growing number of serious problems found in the reinforced concrete structures, according to the research on damage done by Dal Molin in 1998 and Andrade 1997, there has been a growing demand for inspections and the maintenance of residential buildings both in Pernambuco and country as a whole. However, it is possible to observe that the practice of

2. Infestation of rural houses by Triatoma infestans in the region of Los Llanos (La Rioja, Argentina)
Vectorial transmission of Chagas disease has been strongly reduced in most parts of the Southern Cone countries of South America, except in the Gran Chaco region of Argentina, Bolivia, and Paraguay. Given periodical interruptions of the vector control programmes in the endemic region of the Gran Chaco of Argentina, the vectorial transmission of the disease h

4. 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. Confinamento de fónons ópticos em estruturas piezoelétricas periódicas e quasiperiódicas
We study the optical-phonon spectra in periodic and quasiperiodic (Fibonacci type) superlattices made up from III-V nitride materials (GaN and AlN) intercalated by a dielectric material (silica - SiO2). Due to the misalignments between the silica and the GaN, AlN layers that can lead to threading dislocation of densities as high as 1010 cm−1, and a sig

7. Recognition of the DNA sequence by an inorganic crystal surface
The sequence-dependent curvature is generally recognized as an important and biologically relevant property of DNA because it is involved in the formation and stability of association complexes with proteins. When a DNA tract, intrinsically curved for the periodical recurrence on the same strand of A-tracts phased with the B-DNA periodicity, is deposited on

8. The primitive code and repeats of base oligomers as the primordial protein-encoding sequence.
Even if the prebiotic self-replication of nucleic acids and the subsequent emergence of primitive, enzyme-independent tRNAs are accepted as plausible, the origin of life by spontaneous generation still appears improbable. This is because the just-emerged primitive translational machinery had to cope with base sequences that were not preselected for their cod
