Some Physical and Mechanical Properties of Medium-Density Fiberboard Made from Giant Bamboo

The objective of this study was to evaluate the density, density profile, water swelling and absorption, modulus of elasticity and rupture from static bending, and tensile strength of experimental medium-density fiberboards manufactured using Dendrocalamus giganteus (Munro bamboo). The fiber production was carried out through the chemo-thermo-mechanical pulping process with four different conditions. The panels were made with 10% urea formaldehyde resin based on dry weight of the fibers, 2.5% of a catalyzer (ammonium sulfate) and 2% paraffin. The results indicate that treatments with the highest alkali (NaOH) percentage, time and splinter heating temperature improved the physical properties of the panels. The root-fiber interface was evaluated through scanning electron microscopy in fracture zones, which revealed fibers with thick, inflexible walls. The panels' mechanical properties were affected due to the fiber wall characteristics and interaction with resin. Giant bamboo fiber has potential for MDF production, but other studies should be carried out.

Transformação de coordenadas com modelagem de distorções entre SAD69 e SIRGAS2000 com o uso de Thin-Plate Splines

Several countries have been passed by change processes in their fundamental geodesic structure with the focus on the adoption of geocentric reference systems. In Brazil, the adoption of the SIRGAS2000 evolves the coexistence of two realizations from the COrrego Alegre system, two realizations from the SAD69 system and one realization from the SIRGAS2000 system. To make use of products in the old reference systems, methods of coordinate transformation between the existent reference frames are necessary. So, in this paper one solution for the transformation between coordinates from different reference frames, based on Thin-Plate Splines (TPS), that allows the estimation of parameters from one linear transformation and also one non-linear model is presented. The TPS model was developed to work with tridimensional coordinates and in this paper the results and analysis are performed with simulated data and also with data from the official Brazilian Geodetic System (SGB). In the check points from SAD69 stations (realization of 1996 - SAD69/96), the values of RMSE obtained were of 78,2 mm in latitude and 67,5 mm in longitude, before the transformation to the SIRGAS2000. In the comparison between the TPS model and ProGriD (Brazilian software provided by IBGE), the statistical indicators were reduced in 97%, by using the TPS model. Based in the obtained results from real dataset, the TPS model appears to be promising, since it allows improving the quality of transformation process with simultaneous distortion modeling.

Home Cooking and Phenolics: Effect of Thermal Treatment and Addition of Extra Virgin Olive Oil on the Phenolic Profile of Tomato Sauces

Tomato products are a key component of the Mediterranean diet, which is strongly related to a reduced risk of cardiovascular events. The effect of cooking time (15, 30, 45, and 60 min) and the addition of extra virgin olive oil (5 and 10%) on the phenolic content of tomato sauces was monitored using liquid chromatography coupled to tandem mass spectrometry. Concentration of phenolics in the tomato sauces decreased during the cooking process, with the exception of caffeic acid and tyrosol. The main degradation observed was the oxidation of quercetin, since the hydroxy-function at the C-ring of this flavonoid is not blocked by a sugar moiety, unlike rutin. Higher levels of virgin olive oil in tomato sauce seemed to enhance the extraction of phenolic compounds from the tomato, leading to higher phenolic contents in the sauces. Thus, the food matrix containing the phenolic compounds plays a crucial role in determining their accessibility.

Análise comparativa de um documento de adequação curricular

From the ideologies of inclusive education, the development and adoption of new organizational practices in the school curriculum are noted. In this sense, the work presented here aims to report part of implementation and development process of a individual instrument of curricular adaptation (ACI), to students with special educational needs, especially disabilities, or strong disabilities evidences, who were enrolled in mainstream school. This research aim is to present and to analysis comparatively the structure and use of a didactic-pedagogical curricular adequacy tool, employed by the Department of Education City teachers from a city of Sao Paulo. Two different groups of teachers who worked with students with special educational needs participated in this study, the first (G-1) has had contact with the instrument, and the second (G-2) unknown the instrument. The data collection procedure was the application of a questionnaire consisting of 11 multiple choice questions to the sample. It was noted the document evaluation was positive for most participants from G-1, and participants in G-2 show interest in adopting an instrument to facilitate the teacher activity in organization of education process with special educational needs students. In this way, it’s possible concludes that the instrument analyzed ACI was considered by both teachers groups with a useful pedagogical procedure, able to guide them to elimination of procedural barriers to access to the curriculum towards the realization of an inclusive school.

Efeito da aplicação do fluido de corte na usinagem da superliga Nimonic 80A

The nickel alloys have a chemical composition with high tenor of alloy elements which are responsible for the material's mechanical and thermal properties, but also are the main causative of problems during the machining, making the process difficult. The objective of this work is the study of the machining by external cylindrical turning of the nickel based alloy Nimonic 80A, seeking the machining optimization of this alloy, seeking the best condition of lubricant fluid use, providing real increases of productivity without the need of investments in new production means. Besides, the results of this work should offer more detailed information regarding the behavior of this alloy in relation to machining by turning. The machining experiences were accomplished in a specimen of the nickel alloy, considering the machining parameters: cutting speed (75 and 90 m/min), cutting depth (0,8 mm) and feed rate (0,15 and 0,18 mm/v). The valuations were accomplished in a CNC lathe and tools with of hard metal inserts. After each stage of the turning the measures of the cutting length were accomplished, of the waste of the tools through a magnifying glass (8x) and the roughness of the specimen evaluated in each phase of the process, with the aid of a portable roughness meter. Through light optical microscopy it was possible to observe the wear of the cutting tools for each appraised condition. The roughness values, Ra and Ry, for the appraised conditions were always superiors to the theoretical values. After analysis of the results it was possible to end that, the best acting for this work strip tested it was obtained for ap=0,8mm: f=0,15mm/rev and VC=75m/min, what resulted in a larger cutting length (1811 m)

A institucionalização da agricultura familiar no mercosul

The Mercosul project, signed in 1991, represents the union of a political project, characterized by a democratic agreement among its members, with an economical project characterized by the trade liberalization among its regional members and among these with the global economy. So, it was constituted, with the aim to expand the national trades by the integration, to increase the economic development process with social justice. However, the Mercosul follows the historical trajectory of Latin America integration, characterized by models that aimed the economical development from the strengthening of the industry. According to that, the Mercosul politics are priority for economic issues, focused in the industrialization and trade relations, giving less priority to the social demands. In opposition to such ideas, in 2004 was created the Especialized Meeting about Family Farm (Reunião Especializada sobre Agricultura Familiar - REAF) in the Mercosul, that aim to strengthen the public policies of the sector, to promote the commercialization of the family farm products in the region. So, the family farm, a sector historically marginalized from the integration projects, it is institutionalized in the Mercosul. In that way, the aim of this research is to discuss the reasons that leaded to the family farm institutionalization, and also to analyze the advances and problems of the Especialized Meeting about Family Farm
