Desenvolvimento de equipamentos para o mapeamento de áreas infestadas por macrófitas aquáticas imersas

Foi desenvolvido um conjunto de equipamentos com o objetivo de mapear as áreas infestadas por macrófitas aquáticas, auxiliando operações de manejo mecânico, as quais são realizadas por uma colhedora desenvolvida especificamente para essa finalidade. O conjunto de equipamentos foi constituído por um GPS com programa de correção diferencial, acoplado a um palmtop, um sistema com dois teclados ligados em dataloggers e um transdutor de deslocamento linear LT. O GPS, através do palmtop, proporcionava o mapeamento da área de deslocamento, auxiliando o operador na movimentação da máquina, otimizando a operação e evitando, dessa forma, a sobreposição das faixas de coleta na área a ser manejada. Um dos teclados monitorava a movimentação e operação da colhedora, além da presença de obstáculos, como tocos e bancos de areia, enquanto o outro gerava dados sobre a presença de determinada espécie de planta, como E. densa, E. najas e C. demersum, além do nível de infestação destas plantas. O transdutor, instalado na plataforma frontal da colhedora, se movimentava linearmente, gerando informações sobre a profundidade da coleta realizada. Dessa forma, pôde-se observar que o desenvolvimento desse conjunto de equipamentos foi de grande utilidade e auxiliou a operação de controle mecânico de áreas infestadas por macrófitas aquáticas imersas, possibilitando, assim, o planejamento de operações de manejo e controle subseqüentes.

Fungos causadores de podridões pós-colheita em uvas apirênicas no pólo agrícola de Juazeiro - BA e Petrolina - PE

In Brazil, postharvest diseases caused by pathogenic microorganisms are a major problem that causes damage to around 80% of the total fruit production. In the lower middle Sao Francisco river valley numerous studies on identification and control of fungal diseases during postharvest of grapes are needed, in order to minimize losses in this step. In this context, bunches of seedless varieties 'Crimson', 'Sonaka'; 'Superior' and 'Thompson' were collected from July to November 2009, in order to identify and quantify the incidence of pathogenic fungi. The grapes were collected on five farms which specialize in the production of table grapes for export, all located in Juazeiro - BA and Petrolina - PE. During this period, 10 samples were taken. In the fruit farm five plants were used for sampling, and removal of two bunches of grapes per plant, totaling 10 bunches per variety. Subsequently, they were sent to the laboratory of Plant Pathology at UNEB/DTCS where they were placed separately in a moist chamber for 48 hours at an average temperature of 23 degrees C. After this period, isolations of berries and stems in Petri plates containing PDA - potato-dextrose-agar were carried out with 10 repetitions, which were placed on benches under laboratory conditions. From the 8th day on, the presence of Aspergillus niger, Alternaria alternata, Cladosporium herbarum, Lasiodiploidia theobromae was observed, which presented the highest incidence, as well as Rhizopus stolonifer, Penicillium expansum.

Estudo comparativo de dois tipos de painéis de MDP: com adição de papel impregnado e lâminas de bambu

This work is the production of two types of particle boards reconstructed MDP (Medium Density Particleboard), the first with the addition, in the inner layer of particles of impregnated paper, the ratios of 0%, 1%, 5% and 20 %. In the second type of panel MDP was inserted with blades of bamboo species Dendrocalumus giganteus as coatings and structural reinforcement. The MDP panel, used as a basis for both cases has the composition of three layers, two external particles with smaller particle size and an inner layer composed of particles of larger particle sizes. Assays were performed based on physical and mechanical NBR 14.810/2006 for the determination of the board density, thickness swelling, water absorption, moisture content, bending, tension parallel and perpendicular, and testing of particle sizes of the particles did not exists in standard references. The results were analyzed and compared the results of the commercial boards made from 100% eucalyptus, based on the limits specified by the ABNT NBR 14.810/2006. The values of the tests showed similar results indicating normative specifications in a positive way, the possibility of production of MDP with the use of waste paper impregnated. As for the panel with bamboo blades, the tests showed a mechanical performance far superior to MDP market, explaining the study and possible implementation of the bamboo for use where the MDP will suffer greater mechanical stress, such as doors, tops and benches tables

A questão do voto para o adulto analfabeto ou pouco letrado

The Youth and Adult Education is a reality that still stands on the school benches of Brazil. Elderly people historically get more integration in the world when appropriate to the written code. One of the issues that touch this insertion is the right to vote and, more than that, the awareness of the vote of young and adult illiterate or poorly literate. Thus, this project aims to raise throug the point of view of this student how he see himself as voter and what is their role in the democratic consolidation of this act, even if he is in the condition of illiterate or poorly literate. Therefore, a qualitative approach to research will be conducted, in which individual audio recorded interviews will be held, later transcribed and the data will be analyzed in the light of the studied literature, based on the writings of Paulo Freire. Will participate as subjects Teachers of EJA and of study the students enrolled in the Education of Young Adults rooms on the city of Bauru. The results shown in interviews with the teachers confirmed the investigation of expectations in the study of Paulo Freire which has literacy training as part of the citizenship, the results allowed the construction of the profile of a group of students. We also concluded that it was possible to deconstruct the myth of non-political consciousness of the illiterate and the presence of dialogue in pedagogical practice enabling awareness of Educating
