Estudo comparativo de diferentes metodologias analíticas para a determinação de fluoreto

The problem of dental caries in Brazil and around the world took major considerably over the years. In recent decades, with the advent of fluoridation, this problem has been alleviated. Studies have shown, however, that the lack of control in fluoridation leads to several health of the population. The strict control of fluoride levels in the water distributed, therefore, is essential. The objective of this study is to gather information on the status of fluoridation in some area of Brazil and compare different methods for the quantification of that analyte

Revolução constitucionalista de 32: principais motivações da Frente Única Paulista

This paper aims to analyze the Constitutionalist Movement in 1932, trying to understand, more specifically, the political end sought by the Front Unique Paulista, on a literal translation, union of the political parties of São Paulo (Republican Party Paulista and Democratic Party). The research is motivated by the need to understand the political project of FUP with the movement and the existing motivations why it was articulated. The comprehension of the constitutionalists' reasons is relevant to understanding the history of the revolution, from its origin to its outcome. Based on literature and its historical analysis, the paper will demonstrate that the Front, with the advent of the Constitutionalist Revolution of 1932, had as its main purpose regain political control of the state of São Paulo lost with the revolution of 1930. More than the vaunted concern with the implementation of a new constitution for the nation, the FUP leaders had intended to retrieve the lost power with the movement of 30 and the rise of Getulio Vargas to power. Under a banner to fight for a new constitution and the expected change from a totalitarian and centralized state imposed by Vargas for a more autonomous state, the cause of São Paulo enticed sympathy and support from the community, whose social history always harbored separatist ideas, even that they have never been carried out to its ultimate consequences

A importância da experimentação no ensino de química e ciências

The profile of students has changed a lot, mainly due to the advent of new technologies, which in attractiveness has attracted the attention of students, and becoming a difficulty the teacher to attract the attention of the student to class. In this sense, it is needed reformulations in pedagogical practice so that the student's attention turns to science, arousing their curiosity. Thus, in Chemistry and Science Teaching, and lectures must encourage discussions about science, and one of the possible ways to insert dynamic classes is by inserting the trial. Thus, this present course conclusion work aims at presenting and discussing the ways in which Experimentation in Chemistry and Science Teaching has been applied in classrooms, the difficulties of its implementation as a teaching methodology, as well as the advantages and disadvantages of their use depending on the type of approach, training teachers, among other factors

Cana-de-açúcar e álcool combustível: histórico, sustentabilidade e segurança energética

The cane sugar is important since the early days in the history of the country, following the discovery of Brazil since the colonial period, therefore, the culture has an important role in the Brazilian economy, being one of the main products. In the 1970s with the advent of the economic crisis, geopolitical and the possibility of depletion of oil, countries dependent on imported fuel, sought new energy alternatives. In Brazil, it was decreed in 1975 the creation of the National Alcohol Program - PROALCOOL, who had several years of rising, the increase of distilleries and marketing of cars powered with ethanol blend. Due to the decrease in the price of oil the importance of the program significantly reduced, returning to peak only in 1979, ie, the second phase of the program. Conceived as one of the vectors of the national response to the crisis in oil prices '70s, the program persisted at times rising in others not reaching for more than three decades. Brazil is the second largest ethanol producer, second only to the U.S., where the raw material comes from corn, which becomes a bottleneck biodiesel production because it competes with food production. New technologies developed to increase ethanol production combined with sustainability and economic viability are being held, the principal is the second generation ethanol, known as cellulosic ethanol, ethanol plus third and fourth generation.

Classificação híbrida: pixel a pixel e baseada em objetos para o monitoramento da condição da superfície dos pavimentos rodoviários

Monitorar a condição de uso de toda a extensão das rodovias brasileiras é tarefa dispendiosa e demorada. Este trabalho trata de novas técnicas que permitem o levantamento da condição da superfície dos pavimentos rodoviários de forma ágil utilizando imagens hiperespectrais de sensor digital aeroembarcado. Nos últimos anos, um número crescente de imagens de alta resolução espacial tem surgido no mercado mundial com o aparecimento dos novos satélites e sensores aeroembarcados de sensoriamento remoto. Propõe-se uma metodologia para identificação dos pavimentos asfálticos e classificação das principais ocorrências dos defeitos na superfície do pavimento. A primeira etapa da metodologia é a identificação da superfície asfáltica na imagem, utilizando uma classificação híbrida baseada inicialmente em pixel e depois refinada por objetos. A segunda etapa da metodologia é a identificação e classificação das ocorrências dos principais defeitos nos pavimentos flexíveis que são observáveis nas imagens de alta resolução espacial. Esta última etapa faz uso intensivo das novas técnicas de classificação de imagens baseadas em objetos. O resultado final é a geração de índices da condição da superfície do pavimento a partir das imagens que possam ser comparados com os indicadores vigentes da condição da superfície do pavimento já normatizados pelos órgãos competentes no país.

A hymenopterists' guide to the Hymenoptera Anatomy Ontology: utility, clarification, and future directions

Hymenoptera exhibit an incredible diversity of phenotypes, the result of similar to 240 million years of evolution and the primary subject of more than 250 years of research. Here we describe the history, development, and utility of the Hymenoptera Anatomy Ontology (HAO) and its associated applications. These resources are designed to facilitate accessible and extensible research on hymenopteran phenotypes. Outreach with the hymenopterist community is of utmost importance to the HAO project, and this paper is a direct response to questions that arose from project workshops. In a concerted attempt to surmount barriers of understanding, especially regarding the format, utility, and development of the HAO, we discuss the roles of homology, "preferred terms", and "structural equivalency". We also outline the use of Universal Resource Identifiers (URIs) and posit that they are a key element necessary for increasing the objectivity and repeatability of science that references hymenopteran anatomy. Pragmatically, we detail a mechanism (the "URI table") by which authors can use URIs to link their published text to the HAO, and we describe an associated tool (the "Analyzer") to derive these tables. These tools, and others, are available through the HAO Portal website (http://portal.hymao.org). We conclude by discussing the future of the HAO with respect to digital publication, cross-taxon ontology alignment, the advent of semantic phenotypes, and community-based curation.

WATER HOMEOSTASIS, FRAILTY AND COGNITIVE FUNCTION IN THE NURSING HOME

Objective: - To develop and test a practical clinical method to assess frailty in nursing homes; - To investigate the relationship between cognitive status of the elderly and the balance between water compartments of their body composition. Design and subjects: Cross-sectional study, conducted at two nursing homes in Boston-MA. Methods: Body mass and height (Ht) were evaluated to calculate BMI (body mass index, in Kg/m(2)). The cognitive decline was evaluated based on the scores obtained from the Mini-Mental State Examination (MMSE); The extracellular to total body water ratio (ECW/TBW) was calculated after the analysis of TBW from deuterium and tritium dilution and ECW from bromide dilution. Single-frequency BIA analysis data were investigated for resistance (R) and reactance (Xc), plotted in an R/Ht Xc/Ht graph (vectorial analysis-BIVA). The BIVA results of nursing home residents were compared against the data obtained from the NHANES Ill study. TBW and ECW values were compared with a group of free-living elderly volunteers. Results: The ECW/TBW was significantly higher in nursing home residents than in the free-living individuals. BIVA analysis showed significantly higher Xc/Ht values in the reference subjects. The MMSE did not present a significant correlation with ECW/TBW for either gender. Conclusion: We proposed the ECW/TBW ratio and BIVA as surrogate methods for the clinical assessment of frailty. We tested successfully both approaches with nursing home patients and free-living volunteers and compared them to a national data base. The advent of new, portable instruments will enable field tests to further validate our proposed "Frailty Factor" in future studies. We found no correlation between frailty and cognitive decline in the nursing home.

Effects of early compost application on no-till organic soybean

Weed control has always been an important issue in agriculture. With the advent of no-till systems, soil erosion was reduced but herbicide use was increased. Organic no-till systems try to adjust reduced erosion to the no use of herbicides. Nevertheless, this adjustment is limited by the cost of mechanical weed control. This cost may be reduced by improved cultural weed control with cover crops mulches. In this paper we report a study on the application of compost manure on an oats winter cover crop, preceding soybean, instead of on the soybean summer crop. Treatments comprised a control without compost manure, and compost manure doses of 4 and 8 Mg ha-1 applied either on oats in winter or soybean in summer, organized in a randomized block design, with five replications. In summer, plots were split into weed-controlled or not controlled subplots. The timing of application and the manure doses did not affect the oats biomass or the soybean performance. However, in summer, without water stress, the application of manure at 8 Mg ha-1 directly on soybean has reduced weed biomass in this crop.
