Modificação de nanopartículas de óxido de ferro por dextranas

A modificação de nanopartículas de óxido de ferro tem sido motivo de diversos estudos devido ao grande potencial em aplicações tecnológicas, em especial a área biomédica, pela aliança das propriedades magnéticas dos óxidos com a funcionalidade que a dextrana confere a esse material. O presente trabalho tem como objetivo sintetizar e caracterizar o sistema óxido de ferro/dextranas. O óxido de ferro foi obtido pela reação de co-precipitação de sais de ferro (II) e ferro (III) - na razão molar 1:2 - com hidróxido de sódio e a modificação das partículas magnéticas se deu por dois métodos: (I) a co-precipitação na presença de dextrana e carboximetil dextrana e (II) a co-precipitação seguida da modificação. Para modificação proposta pelo método (II) se fez necessário enxertar a dextrana em ácido acrílico, utilizando o íon Ce(IV) como iniciador da reação de polimerização. Nessa etapa se averiguou a concentração de iniciador ótima para a síntese e, através da técnica de espectroscopia de infravermelho, se pode confirmar a eficiência do enxerto. A concentração 0,3% de íon Ce(IV) apresentou melhor distribuição de tamanho, obtidos por análises de microscopia eletrônica de varredura e espalhamento de luz dinâmico, sendo escolhida para síntese junto a partícula magnética. A difratometria de raio X permitiu determinar a formação de estrutura cristalina da magnetita e maghemita, que são muito parecidas entre si, porém os espectros de infravermelho apontaram desdobramentos da ligação Fe - O característica da maghemita. A relação Fe2+/ Fe3+ obtida por espectrofotometria também resultou em oxidação. A estabilidade coloidal dos sistemas foi avaliada através de medidas de potencial zeta. A modificação da partícula magnética com carboximetil dextrana foi equivalente para os dois métodos empregados, entretanto a modificação com ...

Rotational panoramic radiograpy is a widely used procedure for examination of the jaws. Then, the aim of this study was analyse the mandibular growth from images obtained on panoramic radiographs of male and female children with chronological age between 7-10 years old. Craniometrics points were identifyed and linear measurements obtained from mandibular body and ramus. The results showed an increase in mandibular body lenght and mandibular ramus height in both sexes. Statistically significant correlation was found between the total mandibular lenght (from codilion to mental) and mandibular body lenght (from gonion to mental), in male and female children.

Determinação de sacarose no xarope artificial de groselha por medidas de viscosidade: uma abordagem interdisciplinar

The development of the National Curriculum Parameters for High School (PCN) is established from a logic in which the disciplines are integrated and coordinated in order to promote interdisciplinarity. However, there are few didactic-pedagogic activities that enable teachers in practice to reach this goal. In this paper, we propose an experimental activity to be used with High School students, addressing the concept of viscosity from an interdisciplinary perspective between the disciplines of Physics and Chemistry. For that purpose, flow times of sucrose solutions of different concentrations will be measured in a glass Ford and these data will be used to construct a calibration curve, which will be used to determine the concentration of sucrose in artificial flavor syrup of gooseberry.

Medidas de condutividade A.C. e constante dielétrica na perovskita dupla Ca1.2 La0.8 FeIrO6

This work introduces the results from the performing of impedance spectroscopy on the transition metals oxide Ca1.2La0.8FeIrO6. It was sought to understand the behavior of one sample from its impedance spectra for different AC voltages and temperature values and if an applied external magnetic field at room temperature would cause some change on it. The results revealed that the Ca1.2La0.8FeIrO6 at high temperatures shows conductive and inductive behavior and that the resistance increases with frequency, phenomenon known as Kelvin effect. At 150 K, the spectrum real part no longer consists with the theoretical prediction of Kelvin effect, starting to be influenced by the utilized voltages, condition that inexists on theory. At low temperatures (10, 20, 30 K) it was observed resistive and capacitive behavior, being possible on these conditions, associate to the sample a paralel RC circuit in series with a contact resistance with a fitting from the ZSim software. This fitting allowed the obtaining of capacitance, DC resistance and contact resistance values. The application of a 700G magnetic field at room temperature didn't cause changes on the spectra

Qualidade das medidas antropométricas produzidas em unidades de atenção básica à saúde da região de Botucatu-SP, Brasil

The aim of this study was to evaluate the quality of weight measurements produced in Primary Health Care Centers in Botucatu and surroundings. 14 Health Care Centers were included, all of them located in four towns in the area of Botucatu (4,555; 5,656; 18,761 and 128,397 inhabitants). General conditions and scale calibration conditions found in those Health Care Centers were evaluated. In order to evaluate the weight accuracy obtained by the local team, 10 adult users of each Center were addressed by the rater during the service routine in order to get a new weight evaluation, immediately after the measurement made by the team. The statistic method applied for checking the weight measurement held in the Heath Care Center and the scales accuracy was the measurement error technique (MET). The results have showed that out of 19 scales, 6 of them overestimated the weight by 50 grams, 1 of them underestimated the weight by 200 grams and the others were accurate. Evaluated as a group, the result of the scale MET was 44.3g. Regarding the conformity of the measures obtained by the MET of the adults weighing in the Health Care Centers compared to the ones obtained by the researcher, the expected result was obtained in only one Center (< 100g). The results have showed data compromise, rather due to lack of health team training than due to the conditions of the equipment used for the measurement.

Comparação de medidas obtidas por diferentes aplicativos computacionais na obtenção de áreas citrícolas do Município de Botucatu

The great importance of citrus in São Paulo state, particularly in Botucatu city, the and its major expansion in area in recent years and the advancement of techniques for environmental monitoring, such as remote sensing motivated the present research. The aim of this study was the determination the areas and perimeters of citrus in the Botucatu city, São Paulo state, Brazil, obtained through the softwares: Carta Linx, GIS-Idrisi and SPLAN, using aerial colored photographs of 2005, scaled at 1:30000 with longitudinal covering of approximately 60% and 30% laterally. The areas obtained from the aerial photographs and evaluated by Carta Linx presented values closer to the terrestrial reality in determining areas and perimeters, whereas GIS-Idrisi showed discrepancies in the determination of the perimeters, due to working with matrixes. SPLAN and Carta Linx had values for perimeters and areas in close proximity, due to work with vectors.

Diagnóstico e proposição de medidas para o controle das perdas de água no sistema de abastecimento de Guaratinguetá

Over the past two years, Brazil has been facing a major water crisis in its history and the state of Sao Paulo is the one that has been going through worst difficulties. In this scenario, all water users should do everything possible so that the consumption of water resources is carried out in a sustainable manner. In this context, the companies responsible for the public water supply must increase the efficiency of water resource management. It is indispensable combating losses in the public supply system. When there is a non-visible leak in a pipe, the wastewater volume can be high, but in this case, the water returns to nature and continues to participate in the hydrological cycle. The economic loss corresponds to the value added to the product water, which includes the intrinsic costs of exploration, processing and distribution. This damage results in a reduced availability of financial resources of sanitation companies to invest in environmentally friendly solutions. This study aimed to diagnose the water distribution system in the city of Guaratinguetá (SP), held by the Companhia de Serviços de Água, Esgoto e Resíduos de Guaratinguetá (SAEG), to propose measures to combat water loss. Among the proposed measures, there is the monitoring of losses, planning for replacement of old pipes and company awareness as a whole in relation to combat water losses
