Um microfone às formigas: crimes, narrativas e História

Some remarks on how Cultural History has been used in Mathematics Education are the main focus of this paper. It tries to discuss, basically, three works (In Cold Blood, by Truman Capote; O crime do restaurante chinês, by Boris Fausto; and Os protagonistas anônimos da História, de Ronaldo Vainfas) in order to present some perspectivas about narratives and textual elaboration in the field of Historiography.

Avaliação normativa das salas de vacinas na rede pública de Saúde do municipio de Marilia, Estado de São Paulo, Brasil 2008 -2009.

Objective: to evaluate the standardization of vaccination rooms in the Municipality of Marília, State of São Paulo, Brazil. Methods: descriptive and exploratory study, realized in 2008-2009; the instrument used was the Supervision in Vaccination Rooms, of the Ministry of Health; variables analyzed were general aspects of the vaccination room, technical procedures, cold chain, information system, post-vaccination adverse events, special immunobiologicals, epidemiological surveillance and health education; the score achieved classifies the room (90.0-100.0% = ideal; 76.0-89.0% = good; 50.0-75.0% = fair; <50.0% = insufficient); overall index for each point was calculated as the average score of all rooms. Results: technical procedures, information system, post-vaccination adverse events and special immunobiologicals were scored as ideal; cold chain, epidemiological surveillance and health education were scored as good; and to general aspects of the vaccination room, the evaluation was fair. Conclusion: general index for vaccination rooms in the municipality was considered ideal.

Utilização de extratos vegetais em proteção de plantas

Usage of pesticies in excessive doses or in an inadequate way to control diseases, pests and weeds, has promoted significant environmental damage, contamination of animals, intoxication of farmers, among others. These factors lead to occur the resistance of weeds, pests and pathogens, the appearance of iatrogenic diseases, biological imbalance and reduction in biodiversity. Seeking less aggressive alternatives, plant extracts have been used successfully. Compared to synthetic products, they offer great advantages as generating new compounds, which pathogens are unable to inactivate, and are less toxic, of rapid degradation in the environment, they have broad modes of action, and are derived from renewable resources. It should be emphasized that there are some limitations on its use. The extracts have potencial as insecticide, fungicide, herbicide and nematicide and are considered of good efficiency. The methodologies for obtaining can be achieved through cold extraction, open and closed hot system. The use of plant extracts reappears as a promising and unique option for integrated management in plant protection, being considered as an alternative to control plant pathogens, demonstrating excellent results without causing harm to the environment and living beings.

Fatores críticos de sucesso na implementação e gerenciamento do pensamento enxuto: um estudo na manufatura de fitas acrílicas

As a result of the industrial competitiveness increase in recent decades, concern about process improvements has been growing significantly. Lean Thinking principles are being more and more applied in the different sectors of the industry and aim to reduce costs, which can generate satisfactory results for an organization. Besides the application of lean tools on workstations, Lean Thinking seeks cultural change of the employees. Although the concepts of this management philosophy are widely disseminated, many organizations find barriers in their implementation and management. This study seeks to identify and evaluate the critical success factors in the implementation of Lean Thinking based on a qualitative research in the manufacturing environment of a multinational chemical company that produces acrylic tapes for the automotive market

Avaliação da resistência à corrosão da liga Ti-30Ta submetida a diferentes taxas de deformação visando aplicações biomédicas

This study aims to evaluate the corrosion resistance of Ti-30Ta alloy when subjected to different strain rates. Samples of the alloy Ti-30Ta were obtained from the melting of pure elements in the arc furnace in inert atmosphere (argon gas). Then, the samples were subjected to a thermal treatment and to cold worked to obtain bars. After forging, the samples were machined in accordance with ASTME9-09 standard for carried out compression tests. To microstructural characterization, samples were sectioned longitudinal and transversally and embedded in resin. After, the wet sanding and polishing were performed, followed by a chemical attack, in order to study the microstructure under an optical microscope. Microhardness was measured on the samples that were subjected to microstructural characterization by using microhardness tester. Phases were evaluated by x-rays diffraction. Corrosion tests were carried out to evaluate the influence of deformation on the corrosion resistance. Results show that microstructure was not influenced by deformation

Projeto de adaptação do sistema de injeção do túnel transônico para ensaios em bocais de foguete

In this work, the project of a new experimental facility to be installed at the Aerodynamics Division of the Institute of Aeronautics and Space is presented. This new facility will provide means to perform experimental campaigns to analyze the flow behavior at different rocket nozzle concepts using cold gas that will be obtained from a modification of the Pilot Transonic Wind Tunnel air system. The new installation will enable less expensive experiments in a more secure environment, since the cold gas experimental procedures do not demand fuel storage and burn and security procedures are much less severe. Furthermore, experiments can be carried with different types of sensors, commonly used in wind tunnel tests. Also, the optical access is facilitated enabling the use of optical techniques for the characterization of flow properties inside the nozzles, such as pressure and temperature sensitive painting. The full project design and the operation conditions will be showed, as also some technical considerations about the flor behavior in the facility

Caracterização da liga Ti-30Ta após tratamento biomimético associado à incorporação de antibiótico

Surface treatments have been used to modify the surface of titanium alloys. The purpose of this study is to evaluate the surface of Ti-30Ta alloy after biomimetic approach associated to antibiotic incorporation. The ingots were obtained in arc melting furnace, treated and cold-worked by swaging. The surface treatment was performed in two steps: biomimetic treatment and antibiotic incorporation. For biomimetic treatment, first an alkaline treatment (NaOH 1M at 60ºC) was performed, followed by heat treatment and immersion in SBFx5 (Simulated Body Fluid) for a period of 24 hours. In order to incorporate the antibiotic, samples were immersed in a solution formed by drugs plus SBFx5 for 48 hours. The sample surfaces were analyzed by scanning electron microscopy (SEM), X-Ray diffraction (XRD), atomic force microscopy (AFM) and contact angle measurements. The release of antibiotic from coated implants was measured in phosphate buffer saline at pH 7.4 by using UV/VIS spectrometry. Results have shown changes on the surface after incorporating the drug, which is gradually co-precipitated with the Ca-P crystals, forming a uniform and rough layer on the metal surface
