Avaliação da liberação de íon fluoreto de cimentos ionoméricos antes e após a recarga e com proteção da superfície

Objective: To evaluate fluoride ion release from two anhydrous glass ionomer cements (GICs) and two resin-modified GICs (RMGICs) before and after recharge with 2% neutral sodium fluoride for 4 min and after surface protection of the Maxxion R GIC with an adhesive system, a cavity varnish and a colorless nail polish. Method: A stainless steel 2x6 mm matrix was used for fabricating 5 specimens of each material, which were immersed in 5 mL of deionized water, renewed every 24 h. Measurements with a potentiometer were performed on days 1, 2, 9 and 17, in the 1st and 2nd phases, and the specimens were buffered with a TISAB III solution. In the 2nd phase, the specimens were subjected to recharge and immersed again in 5 mL of deionized water. In the 3rd phase, the GIC surfaces were protected and readings were made at 5 min, 24 h, 48 h and 72 h. Tukey's post-hoc and Student's t tests were used for statistical analyses (p<0.05). Results: There was statistically significant difference in the comparison between the 1st and 2nd phases for all materials, except at day 2 for Vidrion R and VitroFil LC. In the 3rd phase, it was observed that for all materials, comparison of the first 5 min with the other times revealed statistically significant differences among the means of fluoride ion release. In the comparison with the other times, both the varnish and the colorless nail polish presented statistically significant difference between 24 and 48 h as well as between 24 and 72 h. Conclusion: The anhydrous GICs were more effective in fluoride ion release and recharge compared with the RMGICs. Maxxion R presented a homogeneous and statistically significant behavior in both phases. All materials for surface protection were efficient and the colorless nail polish had the best behavior.

Rendimento e qualidade de melancia cultivada sob proteção de agrotêxtil combinado com mulching plástico

The ground cover is an agricultural practice that is designed mainly to control weeds, while the nonwoven prevents the attack of pests. The objective of this study was to evaluate the yield and fruit quality of watermelon grown under nonwoven textile protection combined with plastic mulching. The experiment was conducted at the WG Fruits Company, Baraúna, RN. A randomized block design was used in a factorial 3 x 3 + 1 with four replications, and 36 plants per plot, with the first factor of color of plastic used in mulching (black, silver and white) and the second factor nonwoven textile with different times of use (first and third crop nonwoven under textile and without nonwoven) and an absolute control (no mulching and without nonwoven). The production variables evaluated were: yield (commercial, noncommercial, and total fruit yield), and fruit quality (soluble solids - SS, titratable acidity - TA and SS/TA). The use of mulching and protection of plants with nonwoven textile provided a higher yield of watermelon fruits in relation to bare soil with and without nonwoven textile protection. Fruit quality was not affected by the use of mulching and nonwoven.

Los condicionantes y las consecuencias de los asentamientos precarios urbanos como marco de formulación de programas de vivienda, infraestructura y servicios para los grupos de menores ingresos

Analiza los condicionantes económicos y demográficos que influyen en el proceso de surgimiento y expansión de los asentamientos urbanos de los grupos de bajos ingresos, con el fin de formular políticas de vivienda, servicios sociales y de infraestructura más adecuada.
