EFEITO DOS TRATAMENTOS SUPERFICIAIS NAS PROPRIEDADES DO BAGAÇO DA FIBRA DE PIAÇAVA Attalea funifera Martius

The aim of this study was to investigate the effect of surface treatment on the properties of waste piassava fiber with the goal of aggregating additional business value. The fiber surface was subjected to four different treatments. In the present work, it was found that washing the fibers with water partially removed impurities from the surface rendering it rougher. Alkaline treatment removed impurities from the surface, hemicellulose and lignin, improving the flexibility of the fibers. Increasing the concentration of washing agents, times and temperature of treatment promoted intense defibrillation on the fiber surface, reducing its strength.

A imprensa em Avaí: a cidade e o urbano no Avahy-Jornal, 1927-1931

Esta monografia é resultado da pesquisa de iniciação científica “A imprensa em Avaí: a cidade e o urbano no AVAHY-JORNAL, 1927 – 1931”, e tem por objetivo fazer um levantamento e mapeamento de temas sobre as dinâmicas e transformações urbanas da cidade de Avaí - localizada na região oeste paulista -, presentes no periódico “AVAHY-JORNAL” no período compreendido entre novembro de 1927 a dezembro de 1931. Por meio da articulação entre a leitura e fichamento do jornal, documentação específica sobre o município e fontes bibliográficas das temáticas acerca da Cidade e do Urbano, História da Imprensa, História de Avaí, da região e do estado de São Paulo, este trabalho também pretende esboçar uma problematização sobre a questão social, política e econômica de Avaí do final dos anos 1920 e início dos anos 1930, além de analisar o veículo pesquisado

Configurando um AVO (Ambiente Virtual Anise de Abreu Gonçalves D'Orange Ferreira de Orientação): instrumentação de um professor em proposta de incentivo ao uso de TIC e AVA no nível de pós-graduação

In this paper, I will present a proposal for teachers’instrumentation in ICT by the configuration of a virtual learningenvironment (MOODLE) for advising Linguistics graduate students’projects on teacher education and language teaching mediated by digitaltechnologies. The context of the proposal is teaching as work,occasioned by an announcement from the IHE to encourage the use ofICT. Following the theoretical assumptions adopted by the ALTERresearch group, and confronted with the goals set in the text of theannouncement, the instrumentation involved the reorganization ofcontents provided by a graduate course in the research process steps:planning, implementation and dissemination, and of the artifactsaffordances: information, communication and production.

Seismic modelling and ava analysis of hidrocarbon traps

In this study, forward seismic modelling of four geological models with Hydrocarbon (HC) traps were performed by ray tracing method to produce synthetic seismogram of each model. The idea is to identify the Hydrocarbon Indicators (HCI‟s) such as bright spot, flat spot, dim spot and Bottom Simulating Reflector (BSR) in the synthethic seismogram. The modelling was performed in DISCO/FOCUS 5.0 seismic data processing programme. Strong positive and negative reflection amplitudes and some artifact reflection horizons were observed on produced seismograms due to rapid changes in subsurface velocity and geometry respectively Additionally, Amplitude-versus-angle (AVA) curves of each HCIs was calculated by the Crewes Zoeppritz Explorer programme. AVA curves show that how the reflection coefficients change with the density and the P and S wave velocities of each layer such as oil, gas, gas hydrate or water saturated sediments. Due to AVA curves, an increase in reflection amplitude with incident angle of seismic waves corresponds to an indicator of a hydrocarbon reservoir
