15. Estudo de tratamentos com lítio no combate da reação álcali-agregado / Study of lithium treatments in mitigating alkali-aggregate reaction
The alkali-aggregate reaction (AAR) is one of the deterioration processes of concrete that most affects the structures of hydroelectric plants, concrete dams and bridges. In recent years, the efficiency of lithium based compounds to mitigate RAA has been proven in both the prevention and repair of the affected structures. With regards to treatment, the main

16. Hiatoplastia com utilização de prótese de polipropileno revestida pelo grande omento : estudo experimental em coelhos / Hiatoplasty with polypropilene prósthesis wrapped with omentum : an experimental study in rabbits
Hiatoplasty with prosthesis is considered a polemic procedure. Therefore, we decided to study the utilization of polypropilene prosthesís at this anatomical site. Twenty four New Zealand male rabbits were operated on. Polypropilene prosthesis wrapped with omentum used in group 01. Polypropilene prosthesis only ( without omentum wrapping) was used in group 0

17. Estudos voltamétricos e microgravimétricos da deposição em subtensão de cádmio e chumbo sobre filmes finos de selênio / Voltammetric and microgravimetric studies of underpotential deposition of cadmium and lead on selenium thin films
Cd and Pb underpotential deposition (UPD) on gold electrode and selenium thin film, from acid media, were studied using cyclic voltammetry (CV) and electrochemical quartz crystal microbalance (EQCM). Different form of deposition for cadmium and lead were observed on gold electrode and selenium thin film. The presence of one peak in the positive sweep with a

19. ReptaÃÃo de um fio em uma cavidade bidimensional
The term âreptationâ is associated with the type of movement executed for reptiles, specifically the serpents, being used to describe the object diffusion with the topology of the line. The reptation of a wire injected in a cavity is studied through measures of the average quadratic displacement
of a point of the wire, in function of the length h injec Publicado em: 2007

20. Interação de nanotubos de carbono com segmentos de DNA
Single- and double-stranded DNA (deoxyribonucleic acid) molecules can strongly bind to single-walled carbon nanotubes (SWNT) via non-covalent interactions. Under certain conditions, the DNA molecule spontaneously self-assembles into a helical wrapping around the tubular structure of the carbon nanotubes to form DNA/SWNT hybrids, which are both stable and sol

21. Secagem, armazenamento e qualidade de folhas de Cymbopogon citratus (D.C.) Stapf / Drying, storage and quality of Cymbopogon citratus (D.C.) Stapf leaves
The marketing of the medicinal plants is among a very competitive market. In Brazil, in spite of the effective legislation, the plant medicine it is still marketed under uncertain way due to the inefficiency in quality control mainly in the post harvest stage of the plants which serve as the raw materials for the medicines. The Cymbopogon citratus (D.C.) Sta

23. "Estabilização de suspensões aquosas de alumina pela adição de taninos e quitosana quaternizada" / Stabilization of aqueous alumina suspensions by addition of tannin and quaternized chitosan
The ceramic industry provides products for several areas, and new processing techniques became necessary to meet the quality requirements. The objective is to produce more homogeneous green microstructures (bodies before burning), with lower number of micro-defects. Such materials can be produced from aqueous suspensions of aluminum oxide (Al2O3), known as a
