Carvão (Sporisorium scitamineum) e podridão-abacaxi (Ceratocystis paradoxa) em cana-de-açúcar (Saccharum spp.): uma revisão

Sugarcane (Saccharum sp.) is an important grass cultivated in tropical and subtropical regions of the world, such as in Br, Ind, and Ch, and has its biomass being raw material for production of sugar, fuel ethanol, and some other derivatives. Fungal diseases infect sugarcane fields worldwide, damaging crops and thus, causing great economic losses. Fungal specialized structures act during all Pathogen-Host Relationship Cycle (PHRC) (survival, dissemination, infection, colonization, and reproduction of pathogen), maintaining fungal populations in cultivation soil, infecting plants in following crops and vegetative propagation of sugarcane by infected seeds may allow fungal transportation into regions where diseases haven’t occured before. Biotechnological methods and approaches have significantly contributed to understanding of the relationship among parasite and host, as to diseases management (control, detection, and prevention). Some techniques have daily applications in Agriculture, while others are only used in research and to breeding of host resistant varieties. Among notable diseases, smut (Sporisorium scitamineum) and pineapple disease (Ceratocystis paradoxa) are important because they cause damage and losses in sugarcane regions, although there are different periods for each one to occur. This work aims to review the PHRC for each patosystem, the biotechnological methods and approaches and its perspectives in the study and management of these diseases. As environment is an important factor to the effectiveness of PHRC, one chapter is dedicated to Global Climate Change (GCC) and its possible influences over these diseases in a longterm period

Processo de esmerilhamento, polimento e caracterização de um Shear Plate

Shearplate is an optical glass plate having two flat surfaces and a small angle between them. The use of a high quality shear plate is essential to implement shear interferometric technique . The shear interferometry is a technique used to evaluate the light beam collimation. In order to guarantee the shearplate quality , the complete manufacturing process must be thoroughly monitored. In the manufacturing process, the first step consisted of the glass selection. The selected glass has been submitted to the process of cutting, gluing, chamfering, grinding and polishing. Each phase has been strictly monitored. The quality of the final result depends extremely on an appropriate starting condition, which arises from the grinding process, as the polishing process only recovers the brightness of the part, acting on a small scale on the wearing off of the part, as well as not changing the structured obtained in the grinding process. Respecting all stages of the manufacturing process, the quality of the part has evolved to a good result. The best result obtained showed PV distance of 162 nm, slightly less than λ / 4. This result is significant because the dimensions of the piece with respect to the dimensions of the polisher what interferes directly in the results. The closer are the dimensions of piece and the dimensions of the polisher, the greater the difficulty in controlling the propagation of errors

Propagação de rambutanzeiro (Nephelium lappaceum L.) por enxertia

There is great genetic diversity of rambutan plants, thus, to establish commercial orchards culture, it is recommended the use of plants vegetatively propagated. Therefore, this research aimed to determine the best method of grafting, graft protection and type of rootstock for its propagation. The experiment was repeated in two seasons (autumn/winter and spring/summer). The experimental design was completely randomized in both experiments, with four replicates, each experimental unit consisted of 10 plants analyzed in a 4x2x2 factorial with four types of grafting (whip graft-WG; cleft graft -CG; wedge graft-WG; and inverted wedge graft-IWG;), 2 types of graft protection (Biodegradable and plastic) and 2 types of rootstock (without or with leaves). The variables analyzed in this study were: percentage of grafting success, number and length of buds (cm). For grafting performed in autumn /winter, both by cleft grafting as whip graft with biodegradable strip and rootstock leafless provided the best results in propagation of rambutan tree. The best results were observed during the autumn / winter.

In this paper it was evaluated the influence of the relative position of logs on the trees, the type of wood (juvenile and mature wood and pith) and the dimension of sawed wood elements on the velocity of propagation of stress waves into the material on condition. P. taeda L wood (43 years old trees) from Horto Florestal of Manduri (latitude 230 00’ south, longitude 400 19’ west and altitude de 700 m) São Paulo State, Brazil were used, considering its easy growth rings visualization and the better ju regions definition. Six trees were randomly chosen in the plantation. Trees were sawed into 4 logs (2,5 m long each. In each log it was delimited the central board (80mm tick) region and the lateral boards (25mm tick) regions, cons right hand. It were evaluated relation between velocity of stress waves on logs and the correspondent lumber (central and lateral boards), on green condition, on the three main region of the elements (mature wood results obtained revealed the concordance between velocities of stress waves in the material before and after the its mechanical processing. It was also revealed statistical differences between the velocity of stress waves at juvenile wood, mature wood and pith regions.

Modelagem gravimétrica no Lineamento Guapiara, sul do Estado de São Paulo

The Guapiara Lineament is an important geological feature of the State of São Paulo, Brazil, associated with Mesozoic volcanism in the Paraná Basin. This paper aims at the interpretation and modeling of gravity data collected at a semi-detailed scale between Capão Bonito and Apiaí to identify the geometry of crustal partitioning along this lineament. Maps of Bouguer anomaly in the area show a remarkable positive gravimetric anomaly oriented NW-SE, which coincides with the orientation of the greater concentration of dikes associated with the Guapiara Lineament. The crustal model developed from anomalies shows a significant thinning of the crust in the area and corroborates previous studies. The crustal thinning was caused by mantle rise, reflecting the epirogenetic activity generated by the propagation of the divergent tectonic forces that occurred at the margin of the South American Plate during the Cretaceous.

José Marques de Melo e os estudos científicos da folkcomunicação

This paper aims some academic contributions of José Marques de Melo for the study and propagation of Folkcomunication Theory, developed by Luiz Beltrão, in 1967, in his PhD thesis. Marques de Melo, disciple of Beltrão, is one of the most representative names on the set of international scientific studies of communication. Divided in three parts, this text covers theoretical contributions (conception and classification of genders, formats and types of taxonomy of Folkcomunication); dialogues with other thinkers (McLuhan, Morin and Freire) and empirical contribution (internet as a Folk tool). We emphasize that the contributions of Marques de Melo are fundamentals for the new generations to understand the importance of the Folkcomunication and see it as a complex communicational system.
