Fluxo institucional de resíduos de equipamentos elétricos e eletrônicos e identificação de seus potenciais impactos ambientais e na saúde

A preocupação ambiental em relação aos resíduos de equipamentos elétricos e eletrônicos (REEE) vem crescendo muito nos últimos anos devido à presença de substâncias perigosas que podem causar danos ao ambiente e à saúde. O trabalho teve por objetivo investigar o destino de REEE gerados no Campus Quadrilátero da Saúde/Direito (CQS/D) da Universidade de São Paulo (Faculdade de Medicina, Faculdade de Saúde Pública, Escola de Enfermagem, Instituto de Medicina Tropical e Faculdade de Direito), a partir do momento em que os mesmos deixam as dependências da Instituição e identificar potenciais riscos à saúde e ao ambiente, decorrentes das atuais ações de gerenciamento dos REEE nas unidades estudadas. A pesquisa desenvolveu-se em 3 etapas: a) pesquisa bibliográfica e documental; b) visitas às unidades que compõem o CQS/D, e identificação de cinco intituições filantrópicas como principais destinos; c) visitas aos locais identificados para investigar as atividades desenvolvidas para a recuperação de equipamentos, componentes ou materiais recicláveis, com base em um formulário desenvolvido. Adicionalmente, foram realizadas visitas a outros quatro locais de destino de REEE. Foi identificado que as etapas realizadas nas instituições são: recebimento, teste, conserto e desmontagem manual e que o destino dos REEE pode ser considerado problemático, já que os rejeitos acabam sendo descartados como resíduo comum, podendo causar danos ao ambiente e à saúde. Além disso há riscos ocupacionais, pois os trabalhadores, além de não utilizarem equipamentos de proteção individual necessários, nem sempre recebem capacitação para exercer suas funções

Quantificação da desintegração de comprimidos por fluxo ótico em seqüências de imagens de biosusceptometria AC

AC Biosusceptometry (ACB) is a low-cost biomagnetic tool that has been successfully applied on pharmaceutical research to evaluate performance of solid dosage forms. The aim of this work was to evaluate the Horn & Shunck method to access tablet disintegration. To evaluate the HS results was record on video a test with a objet moving in a rail with a constant velocity. The desintegration was recorded on video and ACB, which used have seven pairs of detection coils and a pair of excitation coils to mensure the magnetic ux variation. The signals were ampli ed and digitalized to create images, which were restored by Wiener lter, while the video images are converted to gray scale, both are normalized and binarized and had the optical ow estimation calculated by Horn & Schunck (HS) algorithm. All signals and images are processed and developed algorithm on Matlab. During the tests the ve tablets (500mg ferrite, 375mg excipients, compression 10 to 50 kN) were on a becker between of the ACB system and of the video system, and only touching the surface of the water. With all OF maps calculated was realized the sum of the resultants of each, to get a disintegration process resultant for each compression. Whit that was possible observed the disintegration behaves. For the compression force study the HS components of each sequence was sum, take mean and normalized for sequence's max modulo, therefore can be observed a high growing on less compression tablets. We can conclude the HS algorithm is viable to tablets disintegration data collection and whit that was possible to create a tablets disintegration analyzes protocol, which would be useful on desintegration kinetics study

Simulação numérica de fluxo de águas subterrâneas na bacia do Rio Grande (BA)

The Urucuia Aquifer System represents a strategic water source in western Bahia. Its baseflow is responsible for the flow rate of the main tributaries of São Francisco river left bank in the dry season, including the Rio Grande, its main tributary in Bahia state. This river has a hydrological regime heavily affected by groundwater and is located in a region with conflicts about water resources. The aquifers geology is constituted by neocretacious sandstones of Urucuia Group subdivided in Posse Formation and Serra das Araras Formation. The embasement is formed by neoproterozoic rocks of Bambuí Group. This work focuses on an important tool application, the mathematical model, whose function is represent approximately and suitably the reality so that can assist in different scenarios simulations and make predictions. Many studies developed in this basin provided the conceptual model basis including a full free aquifer, lithological and hydraulical homogeneity in entire basin, null flux at plateau borders and aquifer base. The finite element method is the numerical method used and FEFLOW the computational algorithm. The simulated area was discretized in a single layer with 27.357,6 km² (314.432 elements and 320.452 nodes) totaling a 4.249,89 km³ volume. Were utilized 21 observation wells from CERB to calibrate the model. The terrain topography was obtained by SRTM data and the impermeable base was generated by interpolation of descriptive profiles from wells and electric vertical drilling from previous studies. Works in this area obtained mean recharge rates varying approximately from 20% to 25% of average precipitation, thus the values of model recharge zones varying in this range. Were distributed 4 hydraulic conductivity zones: (K1) west zone with K=6x10-5 m/s; (K2) center-east zone with K=3x10-4 m/s; (K3) far east zone with K=5x10-4 m/s; e (K4) east-north zone with K=1x10-5 m/s. Thereby was incorporated to the final conceptual model...

Based on the fierce competitiveness of manufacturing companies and the planning problems arising from the lack of flexibility and forecasting demand, companies are increasingly looking to reflect on the most appropriate methods to manage its manufacture. Today it is possible to obtain higher gains and lower costs through very efficient tools, this paper uses action-research to model and implement the physical layout of a manufacturing cell, with strong theoretical basement returned to Lean Production System and acting systematically in flexibility in mounting. Through observation and joint action of the observer and staff can report problems that occurred during the phases of planning and implementation of improvements. With the improvement of the physical arrangement in the assembly was possible to obtain significant gains by reducing the production cycle, the manpower required, spending of non-compliance and increasing productivity, final product quality and health in the workplace

Simulação numérica de fluxo de águas subterrâneas na fazenda Cara Preta - Santa Rita do Passa Quatro - SP

The term model refers to any representation of a real system. The use of models in Hydrogeology can be valuable predictive tools for management of groundwater resources. The numeric models of groundwater flow, object of this study, consist on a set of differential equations that describe the water flow in the porous medium. In this context, numeric simulations were made for a sub-basin located at Cara Preta farm – Santa Rita do Passa Quatro – SP. The aquifer at the local is composed by rocks of Pirambóia Formation, which is part of Guarani Aquifer System. It was developed a conceptual model from previous studies in the area, and from that, simulations were made through the software Visual Modflow®. The conceptual model established previously was considered consistent through the results of simulation.

Influência do exercício resistido com restrição do fluxo sanguíneo sobre ativação muscular

Conventional resistance training (TRC) is capable to generate muscular responses according to provided stimuli, as, training volume and intensity. The TRC results in force gains in general. Studies aim this gain to neural adaptation initially, followed by hypertrophy gains. However, studies that used TRC associated to blood flow restriction (RFS) found rise in force and hypertrophy without necessarily detecting rise in neural activity. Therefore this review had as objective, bring up literature data that report this fact and yet, speculate possible elucidation about this responses inversion

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

Aplicações do fluxo de Ricci à teoria da relatividade geral: estudo dos buracos negros

The flow of Ricci is an analytical tool, and a similar equation for heat geometry, a diffusive process which acts on a variety of metrics Riemannian and thus can be used in mathematics to understand the topology of varieties and also in the study geometric theories. Thus, the Ricci curvature plays an important role in the General Theory of Relativity, characterized as a geometric theory, which is the dominant term in the Einstein field equations. The present work has as main objectives to develop and apply Ricci flow techniques to general relativity, in this case, a three-dimensional asymptotically flat Riemannian metric as a set of initial data for Einstein equations and establish relations and comparisons between them.
