Matemática comercial e financeira com a utilização de recursos digitais: uma experiência no ensino médio

This work aimed to investigate the possible contributions of the use of digital resources in the teaching and learning process of Commercial and Financial Mathematics concepts to high school students. Its development has included a survey of some researches on the topic as well as an experimental study of a qualitative type, in which the Webquest was used as methodology. It uses the computer, more precisely the internet resources, to assist students in building up knowledge. Eight meetings were held, in the after-school period, with a group of students of the second year of high school at a state public school in the city of Guaratinguetá. Aiming to evaluate the knowledge that students had about the theme, it was applied a diagnosis at first glance for further analysis and development of activities and interventions according to the students’ answers. Once the research data was analyzed, it was noted that the students had little knowledge regarding the basic contents of Commercial and Financial Mathematics, in addition to presenting difficulties in handling some of the digital resources used in the meetings. Nonetheless, from the students’ works, it was seen significant advances in understanding and building up knowledge on concepts such as percentage, simple and compound interest, savings, and sales involving prompt payment or in arrears

Estudo de uma ponte rolante comercial no transportede bobina de aço de 12 toneladas

This work aims to determine the stresses acting on the main beam of a crane to transport steel coils of up to twelve tons. To determine the stress it was made a revision of the knowledge of the mechanics of materials to apply the analytical method. Following a review of the finite element method is made to understand the same. To complete the study it was used the commercial software ANSYS to determine the stresses by finite element method, the program provides images that help to better understand the results obtained. With the results a comparison of the values of the tensions between the two methods (analytical and finite element) was made. To assist in the calculations it was used the NBR 8400, 1984 (Calculation of Lifting Equipment Load)

Análise de matérias primas e solução comercial empregada na perfusão e no transporte de órgãos destinados ao transplante

A solução HTK (histidina, triptofano e cetoglutarato) foi especialmente desenvolvida para preservar a heterogeneidade morfológica e bioquímica dos órgãos destinados ao transplante. Contém exclusivamente substâncias existentes no organismo tais como cloretos de sódio, potássio e magnésio, histidina, triptofano, manitol e cetoglutarato de potássio. Sua composição promove a inibição de todos os processos de ativação muscular, nervosa ou endócrina nas estruturas estimuláveis das membranas. Nos compêndios oficiais encontram-se métodos de análise qualitativa e quantitativa para matérias primas. Análises das matérias primas foram realizadas nos Laboratórios de Controle de Qualidade da faculdade de Farmácia e Laboratório de Eletroanalitica (NDcom) do Instituto de Química aplicando os métodos preconizados nos códigos oficiais. Os resultados obtidos com as matérias primas foram satisfatórios e confiáveis. Os mesmos métodos não possibilitaram a análise da Solução HTK acabada como proposto inicialmente. Esses métodos não apresentaram sensibilidade suficiente para a determinação das matérias primas empregadas no preparo desta solução, pois estas se encontram em concentrações bastante reduzidas, necessitando métodos mais sensíveis que realizem análise de traços de eletrólitos.

Simulação de ciclo combinado utilizando software comercial

In Brazil, The power generation has always depended on the rivers, in other words, there are moments that the power generation can vary, which can cause variations in energy supply and even blackout according to the level of water in the reservoirs of the hydroelectric plants. For this reason, many options has been studied, like our example, which is about a combined cycle power plant in Canas. The use of combined cycle is interesting from the point o view of energy, because its efficiency is between 50 and 60%, and from the point of view of environment, because it can burn natural gas, which is cleaner than coal, it reduces the emission of gases that influence on the greenhouse effect. This work aims to perform a technical analysis of a case study of a power plant proposed to be built in Canas by the AES/AES Tietê Group. For the analysis will be used the commercial software GateCycle 6.0.0 from GE, this software has the power of simulating power generation cycles (nuclear, combined, etc.). The energy department of UNESP has the license, which makes possible the academic use of this tool. Two combined cycles were simulated, one using one pressure level HRSG, and another one closer to the real power plant, which is a combined cycle with a three pressure level HRSG. The results were close to expected, for the combined cycle with one pressure HRSG the power was 513,9 MW and a efficiency of 53,27%, in the case with the three pressure level HRSG the power was 517,1 MW and a efficiency of 53,5%. We conclude that the software requires that the user must have the knowledge about the subjects involved in the use of GateCycle in problems resolutions

Análise da proposta de melhoria do fluxo na área comercial central do municípo de Rio Claro-SP

The development of medium-sized cities in recent decade, caused, partly, by the industrial deconcentration process generated, beyond benefits, several problems for these cities population. The unplanned rapid growth of these cities, together with the capitalist model of production collaborated for the increase of socioeconomics questions in these locations. The urban mobility became one of these problems, embarrassing citizen’s lives, especially in downtown area. Therefore, the State began looking for solutions to improve urban mobility of the population, contributing to their quality of life and also to adapt the city to new market demand. In these work, we analyzed the situation of Brazilian medium-sized cities downtown area, as well as its growth process, tanking as an example the case of the city of Rio Claro – SP and it´s Public Administration proposal to improve the flow and urban mobility in a particular street in the town´s commercial centre

Validação de aplicativo comercial visando a incorporação da realidade aumentada a um modelo de avaliação pós-ocupação

Post-Occupancy Evaluation of buildings considers user satisfaction, building pathologies and performance, as well as users interventions in the built environment. The possibility of identifying interventions regardless of the user could provide a significant gain in the efficiency of Post-Occupancy Evaluations. We foresee the application of Augmented Reality (AR) to improve the identification of renovations by overlapping the construction information model with an image of the actual building. This article validates the use of AR on existing smartphone and tablet applications. This study proposes the incorporation of AR into the planning, execution and application of Post-Occupancy Evaluation. For the planning, this study proposes the development of a new research tool. With regards to the execution, this study examined the data collection conditions on site through the visualization of overlapping models. For the application, this study proposes displaying the results through the use of RA information layers. The transparency oft he RA model was used to allow comparison between the virtual model and the real model. The development and adaptation of the virtual model and the solution developed for the experiment of the RA proposal are presented and discussed. The experiment points to shortcomings that still make the proposed technological solution unfeasible.

Praça comercial em Bauru-SP

A partir da problemática dos centros comerciais fechados e que se relacionam pouco ou nada com seu entorno, principalmente áreas públicas, este trabalho busca estabelecer um panorama histórico do consumo, dos estabelecimentos comerciais, e sua relação com o lazer e com o encontro cada vez mais evidente, para propor uma intervenção na cidade de Bauru - SP, em uma localidade consolidada, porém alvo de questões como especulação imobiliária e falta de opções qualificadas de lazer. A área de intervenção apresenta uma praça pública imediatamente ao lado, a qual é bastante frequentada em determinados horários (condicionado à um consumo alimentício), porém recebe pouca manutenção. Este trabalho busca entender as relações existentes atualmente neste local e propor um novo empreendimento que diversifique as opções presentes e possa contribuir para uma melhora estrutural, cultural e social do espaço urbano
