Avaliação clínica e radiográfica de pacientes submetidos ao levantamento da membrana do seio maxilar

Implant dentistry is a dental specialty which presents great predictability in the rehabilitation at posterior, partially edentulous maxillary areas. Early tooth loss results in significant jaw remodeling. The maxillary sinus lifting followed by implant placement is a predictable technique initially described in 1980. Since then, several different techniques have been investigated varying filling materials and the management of complications in order to provide effective guidance in the rehabilitation of these patients. The current study evaluated ten patients who underwent sinus lifting before implant placement and crown installation. First, a retrospective analysis of the medical records was conducted to obtain information about possible postoperative complications. Clinical and radiographic analyses were performed at baseline and 180 days after surgeries. The sinus lifting with immediate implant placement provided satisfactory outcomes and can be considered a safe procedure. Treatment predictability was demonstrated in 90% of patients and for 86.96% of implants placed. It is important to highlight knowledge of anatomical structures at this area, the use of delicate surgical techniques, and strict patient follow-up.

Uso da cromatografia gasosa para avaliação da difusão em membrana de Polietileno de Alta Densidade (pead) em contato com hidrocarboneto

The constant petrol fuel leak in gas stations has caused concern in many countries around the world. Those fuels have toxic organic compounds in their composition, like Polycyclic Aromatic Hydrocarbons (PAH), which are harmful to the human health. In this work the efficiency of the protection layer with a High Density Polyethylene (HDPE) membrane of 2.5 mm thickness was evaluated. The study was based in the diffusive process in the intact membrane by a permeameter developed to evaluate the diffusive process. The membrane was putted in the middle of the system to separate two sides: a local soil impregnated with diesel oil (in one side) and pure water (in the other side). The chromatography technique was conducted to evaluate the contamination in the pure water. The analyses were made monthly in a total period of 6 months of research. The results tests show that the membrane was less effective to antracene and naphthalene compounds. Despite that, the results showed that the HDPE membrane is a good alternative to prevent contamination of water and soil by the compounds under study up to one year, based on the performance in the time of study.

A lógica matemática da arte ornamental: uma relação de equivalência a partir da estrutura atômica dos cristais

Based in aesthetic relationship between concepts of content and form intends to establish an relationship of analogy between ornaments and crystals. With the objective of building an theoretical investigation of relating the dynamics that happens in the crystals´ atoms to the symmetrical intervals of the ornamental patterns, it tries to draw a reasoning line that is going from the ‘Idea’ of Plato and ‘poiésis’ of Aristotle, until Hegel's philosophical enlargement, that admits the aesthetics as a science of the art integrated in a metaphysical process. Inherent to this question intends, in interrelation terms between aesthetics and metaphysics, content as being intelligent beginning, energy, and form as primitive element, matter, in order to evidence the possibility to calculate the same present symmetries in the ornamental arts like in the nature.

Efeito da vinhaça na membrana impermeabilizante usada nos tanques de armazenamento

This work evaluated the effect of vinasse (residue from sugar cane) in high density polyethylene (HDPE) geomembranes having in mind that it is deposited at temperatures of 80-90˚C on the geomembrane in storage tanks. The objective was to evaluate the resistance of the geomembrane in contact with residue in a total period of 4 months. Physical and mechanical tests, and thermogravimetric analysis (TGA) were used to determine degradation of polymer membranes after chemical immersion. In general, the results obtained show that the vinasse affected the geomembranes significantly in some aspects, for instance, the thickness of the material presented a variation of 7.8%. The average values in both directions at yielding showed a significant loss of tensile strength (34.13%) and strain (23.48%) and an increase in the modulus of elasticity (9.63%). At the rupture the behavior presented the same trend: a loss of 32% for tensile strength and 24.4% for the deformation were observed. Tear strength presented small decrease (4.72%) and puncture resistance a increase of 7.9% after immersion of geomembranes. The TGA tests were not efficient to detect evidence of degradation in samples of geomembranes after exposures, but identified problems in the quality of the supplied material.
