1. GAS EXCHANGE IN ‘POME’ BANANA PLANTS GROWN UNDER DIFFERENT IRRIGATION SYSTEMS
Abstract This study aimed to evaluate Pome type bananas grown under different irrigation systems. Seventy-two treatments were used in a factorial 3×2×12 scheme, where factors consisted of three irrigation systems (under-tree sprinkling, micro-sprinkling, and dripping), two cultivars (‘Prata-Anã‘ and ‘BRS Platina’), and twelve evaluation periods (m

2. Influence of disinfectant solutions on test materials used for the determination of masticatory performance
Masticatory function can be evaluated objectively as the capacity of an individual to fragment solid food after a fixed number of chewing cycles, the so-called masticatory performance (MP). The objective of this study was to evaluate the reliability of four different test materials (Optosil, Optocal, Zetapuls, and Perfil) and five disinfection protocols by a

3. Variabilidade espacial da uniformidade da lÃmina de Ãgua aplicada por sistemas fixos de irrigaÃÃo por aspersÃo / Spatial variability of water level uniformity applied by fixed sprinkler irrigation systems
Water application uniformity is an important factor to be considered in the evaluation of sprinkler irrigation systems. The uniformity depends on the type of sprinkler and its operational conditions, the display and space among the sprinklers on the field, and also the wind speed and direction during the water applying period. This work contributes to develo

6. IrrigaÃÃo e fertirrigaÃÃo em um sistema de aspersÃo convencional submetido à tÃcnicas de controle estatÃstico de qualidade. / Irrigation and fertigation in sprinkler system submitted to techniques of statistical quality control
The contribution of irrigation in the alimentary supply, is due to the fact of more and more to look for more efficient systems, monitoring the indexes of uniformity of distribution of the water. The application of fertilizers through irrigation water took very big pulse in the last times, mainly due to the emergence of pressurized systems, of the tunnels of

10. Biomateriais: deposição de hidroxiapatita sobre superfície de Ti-cp modificada por aspersão térmica
The osseointegrated titanium implants are reliable and safe alternatives to treatments for long periods of time. For surface modification, thermal aspersion of TiO2 was used. The samples with and without TiO2 were treated with NaOH and SBF in order to obtain a layer of HA. Characterization was done by SEM and FTIR. The images of HA obtained by SEM show a uni
