Topobatimetria e geração de modelo digital de terreno no monitoramento da dinâmica fluvial do ribeirão Guaratinguetá

This research was developed with the goal of creating a Digital Terrain Model(DTM),through a topo-bathymetric data gathering that allows the monitoring of the fluvial dynamics of part of Guaratinguetá’s creek, where preliminary evaluations identified, in a short period of time, intense changes on its riverbed. Modern topography technics and tools were used for the data gathering, such as the use of geodesic GPS and Total Station. The DTM was primal for the project e execution of the desilting works of the researched part of the creek, being used to estimate the amount of soil to be moved. The comparison between the digital terrain models generated before and after the desilting has showed the efficiency and aplicability of this technique in the monitoring of the fluvial dynamics changes of Guaratinguetá’s creek

Métodos de pontos interiores e o planejamento de tratamento de câncer por radioterapia

O câncer é uma doença que tem início quando ocorre uma mutação genética no DNA da célula, onde o mecanismo de controle do crescimento normal do tecido celular é alterado. O tratamento do câncer por radioterapia tem como objetivo a eliminação das células cancerígenas ou alívio dos sintomas. Este trabalho visa estudar conceitos envolvidos no planejamento do tratamento de câncer por radioterapia, o modelo de programação linear, os métodos Primal-Dual-Afim-Escala e Primal-Dual-Clássico e apresentar uma aplicação dos métodos para problemas gerais de otimização

Trabalhadores hóspedes: herders, borregueros ou peões nas montanhas rochosas dos Estados Unidos e Canadá

In the contemporary world and in the globalized farm labor market, employ temporary immigrants workforce become current in economic developed countries. With governmental support, nations as United States and Canada incite and lawful the foreign entrance for occupy jobs and functions that are not fulfilling by native born, consolidating the displacement of a cheap labor force that stays legally for a certain season in these countries. This article brings up primal subjects about a small and hidden group among farm immigrants, the herders, sheepherders and goat herders in northAmerica Rocky Mountains loneliness. Further to provide an initial theoretical instrumental for the reflections about these workers, we intend to localize them within migration theme and the conflict between capital and labor in these days, in its neoliberal context and struggle forms. For such, we used reflections about labor and migration, also different kind of documents about herders in both countries.

Biorremoção de corante direto de efluente industrial simulado utilizando levedura liofilizada

One of the most primal ways of human work already known is the tessellation and ginning for the production of fabric and clothing - what used to be, back in those days, statement of power and status. The arrival of the Industrial Revolution - in the middle of the XVIII century at Britain - increased the textile industry production, and what used to be manufactured and hard to obtain, starts then to be produced in mechanical ways and large-scale. Despite all the boost given to the economy of an expanding capitalist market, it should be pointed out the consequences of this major industrialization, especially the environmental ones, more and more concerning nowadays. The emissions of waste - that sometimes could be toxic - in effluents can possibly contaminate the aquatic ecosystems, causing a huge damage to its fauna and flora, affecting therefore all the biodiversity, reaching inclusively the humans. To avoid these problems, a few strategies have been taking place in the attempt to eliminate - or at least reduce - the amount of dye found in the effluents, and as the textile industry constantly leaves waste, efficient methods - that present good results in a short period of time - with a low cost are needed. The present study will test the bioremoval capacity of yeast (Saccharomyces cerevisiae) in contact with dyes in a fix concentration, diluted in water with three different pH values. The tests will be done duplicate, and after the concentration analyses - made by spectrophotometry - it will be analyzed which pH shows major efficiency in the dye removal and what is the influence of the biomass in this process
