The importance of maintaining a healthy intestinal microbiota in the health of the host has been increasingly clarified. This microbiota may appear unbalanced in diseases such as colitis, diarrhea, irritable bowel syndrome and constipation. To rebalance the microbiota and improve the symptoms of constipation, it is recommended to intake prebiotics, probiotics and symbiotics, which works in the modulation of a healthy intestinal microbiota and favors the production of short-chain fatty acids that have a positive effect on intestinal transit. In addition, some studies indicate that there is a relation between the brain and the intestine that influences the behavior of individuals with intestinal dysbiosis. Thus, the reestablishment of the eubiosis in constipated patients through the functional compounds (prebiotics, probiotics and symbiotics) has been showing promising results regarding the modulation of constipation and improvement of the clinical picture. This review will emphasize the relation of prebiotics, probiotics and symbiotics in the modulation of intestinal constipation. New food sources of these compounds should be evaluated for their efficacy, dose and effect to establish a proper management.

This article shows an innovative method to model and validate the hot air flow through the blast furnacés tuyeres. This study will be the basis for flow measurements implementation and safety interlocks for the pulverized coal injection. The flow measurements were taken in the blast furnace down leg pipes by installing refractory Venturi tubes. The system for the calculation of differential pressure takes into consideration the dimension of the Venturi, the air density and compressibility. The objective is to specify the flow transmitters required to automate a control system and implement safety interlocks for the coal injection plant.

Deaf people face communication difficulties in health units because of the lack of preparedness of health care professionals to deal with these patients. Objective: To identify how physical rehabilitation professionals associated with a regional public unit in the south central region of Rio de Janeiro State, Brazil interact with deaf patients. Method: Data were analyzed through descriptive statistics in the Statistical Package for Social Sciences (SPSS) software version 18. Results: Results showed that: 15.1% (5) of the team members did not know the Brazilian Sign Language (Libras) and required help in their interaction with deaf patients;12.1% (4) never assisted deaf patients;18.2% (6) used writing and gestures;21.2% (7) resorted to lip-reading or gestures;3.1% (1) spoke slowly;6.1% (2) used mime;15.1% (5) used the Brazilian Sign Language;9.1% (3) did not respond. conclusion: Most of these professionals are not prepared to satisfactorily interact with deaf patients. They use improvised strategies to assist the deaf clientele, demonstrating that the planning and implementation of regular courses in sign language are fundamental in order to assist these patients effectively.

The increasing demand for reducing vehicle weight in the automotive and aerospace industries has raised the need to develop improved structural aluminum-based alloys. Thus, horizontal solidification experiment with the Al-7%Si-0.3%Mg（mass fraction） alloy was carried out. A water-cooled horizontal directional solidification device was developed and used. Microstructural characterization was carried out using traditional techniques of metallography, optical microscopy and SEM microscopy. The Thermo-calc software was used to generate the solidification path of the investigated alloy with addition of 0.17% Fe（mass fraction）. The effects of the thermal parameters such as the growth rate（VL）, cooling rate（Tc） and solidification local time（tSL） on the formation of the macrostructure and on the dendritic microstructure evolution were evaluated. A columnar to equiaxed transition（cET） was found for VL and Tc values from 0.82 to 0.98 mm/s and from 1.71 to 2.55 ℃/s, respectively. The microstructure was characterized by the measurement of the primary and secondary dendrite arm spacings（λ1 and λ2, respectively）. Experimental laws of λ1 =f（VL, Tc） and λ2 =f（tSL） were proposed. It is observed that the interdendritic region is composed of the following eutectic mixture： a（Al）＋Si＋p-Al8 Mg3 Fe Si6＋q-Mg2 Si.

cubiu fruits (Solanum sessiliflorum Dunal, Solanaceae) are known for their high nutritional value and low caloric content. This work aimed at evaluating biochemical indices of cubiu fruits according to different tissues (peel, pulp and placenta) and ripening stages (green, turning, ripe and fully ripe). The fruits were randomly harvested to investigate sensory aspects (colorimetry, blanching effect, pigments) and biochemical indices (moisture and dry matter, Total Soluble Solids (TSS), pH, Titratable Acidity (TA), TSS/TA ratio, ascorbic acid, Alcohol-Insoluble Solids (AIS), pectinesterase activity and pectin content). The analyses were performed at the laboratory of Instituto Nacional de Pesquisas da Amazonia (INPA), Manaus, Brazil. The blanching process preserved pulp colors at all ripening stages. chlorophylls were higher in green peels;flavonoids and carotenoids, in fully ripe peels. Anthocyanins were entirely absent. Pulp (turning fruits) showed the highest moisture content (91.05), followed by ripe pulp (90.70) and fully ripe pulp (90.62). Pulp TSS changed little whereas placenta TSS declined and were associated with increased TA and pH reduction (fully ripe fruits). Pulp pH and TA varied little whereas placenta pH was notably low and TA was remarkably high (fully ripe fruits). Pulp TSS/TA ratio showed predominance of TSS while in placenta, there was predominance of organic acids. AIS, precursors of pectin, were stable during ripening. The statistical analysis of dietary fiber content showed one modal value in the AIS. In pulp, pectinesterase activity correlated inversely with pectin content. cubiu fruits were significant sources of bioactive compounds, e.g. chlorophylls, flavonoids and carotenoids, predominantly in the peel and the pulp;soluble functional fibers, e.g. pectin (g/100 g fresh weight), particularly in the green peel (1.00) and the fully ripe pulp (1.12), and other versatile molecules, e.g. ascorbic acid (mg/100 g fresh weight), especially in the f

Gold-iron oxide nano-heterostructures with a clear and well-defined morphology were prepared via a seed-assisted method. The synthesis process and the events of heterogeneous nucleation during the decomposition of the iron precursor were carefully studied in order to understand the mechanism of the reaction and to tailor the architecture of the fabricated heterostructures. When employing Au seeds of 3 and 5 nm, nanoparticles with a dimer-like morphology were produced due to the occurrence of a single iron oxide nucleation event. Otherwise, multi-nucleation events could be favored by two mechanisms:(i) by the incorporation of a reducing agent and the slowing down of the heating protocol, leading to a core-shell system;(ii) by the increase of the Au seed size to 8 nm, leading to a flower-like system. Further increase of the Au seed size to 12 nm using similar synthesis conditions promotes the homogeneous nucleation and growth of the iron oxide phase, without formation of heterostructures. An in-depth study was performed on the gold-iron oxide heterostructures to confirm the epitaxial growth of the oxide domain over the Au seed and to analyze the elemental distribution of the components within the heterostructures. Finally, it was found that the modification of the plasmonic properties of the Au nanoparticles are strongly influenced by the architecture of the heterostructure, with a more pronounced damping effect for the systems produced after multi-nucleation events.
