Rendimento do suco e qualidade química do abacaxi sob lâminas e frequências de irrigação

The pineapple crop has a permanent demand for water, variable and dependent on their stage of development, which may affect the production and fruit quality. This study aimed to evaluate the chemical quality of fruits Smooth cayenne pineapple submitted to different levels and frequency of water replacement in the soil. We used a randomized block design in a 4 x 2 factorial arrangement, consisting of four levels of soil water replenishment (50%, 75%, 100% and 125% of crop evapotranspiration) and two irrigation frequencies (1 and 3 days) with four replications. We evaluated the parameters: juice yield (RS), hydrogen potential (pH), total soluble solids (SST), titratable acidity (ATT), SST/ATT relationship, ascorbic acid (AA). It was observed that the blades and irrigation frequencies did not affect the juice yield (RS) and ascorbic acid (AA), the increase of the blades irrigation influenced positively the quality of the fruit as it increases the values of total soluble solids (SST) decreases the acidity (ATT), raises the relationship SST/ATT and hydrogen potential (pH).

Cinética do VO2 durante o exercício realizado na potência crítica em ciclistas e indivíduos não-treinados no ciclismo

The objective was to analyze the oxygen uptake (VO2) kinetics during exercise performed at critical power (CP) in subjects with different aerobic status in cycling. Six trained cyclists (GT) and seven non-trained subjects (GNT) underwent to the following protocols in cyclergometer: (a) incremental to exhaustion to determine VO2max and its respective workload (IVO(2)max); b) three square-wave tests to exhaustion at 95-110% IVO2max to determine CP, and; (c) one square-wave test to exhaustion at 100% CP. During the exercise at CP the slow component expressed as absolute value (GT: 342.4 +/- 165.8 ml.min(-1) vs. GNT: 571.3 +/- 170.1 ml.min(-1)) and as the relative contribution to the increase of VO2 during exercise (GT: 10.0 +/- 4.6% vs. GNT: 26.6 +/- 7.3%) were lower for trained subjects. The VO2 at the end of the exercise at PC (GT: 89.8 +/- 8.4% VO(2)max vs. GNT: 97.4 +/- 2.8% VO(2)max) was significantly lower in GT (rho = 0.045), and similar to VO(2)max in GNT. Therefore, the aerobic level might influence the VO2 responses to exercise at PC

Estudo experimental do polietileno poroso de alta densidade (MEDPOR) fixado ao leito cirúrgico corticalizado e decorticalizado: análise histológica em cães

The aim of this study was to evaluate the influence of the bed in High Density Porous Polyethylene (Medpor) implants integration. Two different kind of beds -- corticalized and decorticalized -- were made in six dogs. The animals were killed thirty, sixty and ninety days after implantation. Blocks including implant and adjacent bone were harvested, submitted to histological procedures, stained in hematoxiline-eosine and analyzed in optic microscope. The results demonstrated an absence of infection and foreign body reaction associated with High Density Porous Polyethylene (Medpor) implants. Furthermore, bony and fibrovascular ingrowth could be observed into its pores. The best integration was noted in decorticalized group, in which occurred a greater bony and fibrovascular ingrowth in comparison to the corticalized group

Recursos de Alta-Tecnologia Assistiva Disponíveis no Mercado Nacional:ferramentas para alunos com paralisia cerebral

In Brazil, the interest on the applicability of assistive technology resources in the school environment has grown for children with cerebral palsy, according to the evidences on the diffi culties in their process of scholarization. The objective of the project was the construction of a data base about the resources of high assistive technology in the national market, indicated for the use in the classroom environment for children with cerebral palsy, with the purpose to systemize information, to assist in the selection, prescription and implementation of this type of resource. From a search in the literature available in existing national sites, a computerized archive on the availability of these resources was constructed, having as parameters the applied methodology already used in previous study. Therefore, information on adapted resources had been systemized, constituting an accessible source of data to all the interested parties, aiming to contribute for a effective implementation of these resources in the promotion of the scholarization of children with cerebral palsy in the country.
