Comportamento estomático do porta-enxerto CCP 06 e da muda enxertada CCP 76/06, submetidos aos estresses hídrico e salino.

A expansão da cajucultura está apoiada, basicamente, no uso de um único porta-enxerto, para o qual há carência de estudos da interação ambiente e clone enxertado, especialmente dos efeitos dos estresses hídrico e salino, que contribuem para a redução do crescimento e da produtividade das plantas.bitstream/CNPAT-2010/9022/1/Bd-009.pd

Rural-urban migration in d-dimensional lattices

The rural-urban migration phenomenon is analyzed by using an agent-based computational model. Agents are placed on lattices which dimensions varying from d=2 up to d=7. The localization of the agents in the lattice define their social neighborhood (rural or urban) not being related to their spatial distribution. The effect of the dimension of lattice is studied by analyzing the variation of the main parameters that characterizes the migratory process. The dynamics displays strong effects even for around one million of sites, in higher dimensions (d=6, 7).Comment: 9 pages, 7 figures, to be published in International Journal of Modern Physics C 1

\u3ci\u3eIn Situ\u3c/i\u3e Degradability of Hand Harvested or Extrusa Samples of Tanzania Grass (\u3ci\u3ePanicum maximum\u3c/i\u3e, Jacq.)

In order to compare the in situ degradability of tanzania grass samples obtained as by extrusa or hand plucked, three ruminal fistulated cows were used in a completely randomized block design with split-plot scheme. Five grams of extrusa or hand harvested grasses were placed in nylon bags rumen incubated during 3, 6, 12, 24, 48, 96 and 120 hours. The degradability of DM, CP, NDF and ADF were, in this sequence, 62.59, 80.88, 50.73 and 46.65%, for hand harvested grass; and 79.53, 90.97, 71.21 and 65.68%, for extrusa. In situ degradability data of hand harvested samples were not reliable

40 Gb/s wavelength multicast via SOA-MZI and applications

40 Gbit/s wavelength multicast is demonstrated by all-optical multi-wavelength conversion based on a single interferometer. Simultaneous 200 GHz spaced one-to-four conversion is achieved, error free until BER of 10-10 and with negligible sensitivity difference among all the multicast channels. Several new all-optical applications are also enabled by this technology

An international network to monitor the structure, composition and dynamics of Amazonian forests (RAINFOR)

The Amazon basin is likely to be increasingly affected by environmental changes: higher temperatures, changes in precipitation, CO2 fertilization and habitat fragmentation. To examine the important ecological and biogeochemical consequences of these changes, we are developing an international network, RAINFOR, which aims to monitor forest biomass and dynamics across Amazonia in a co-ordinated fashion in order to understand their relationship to soil and climate. The network will focus on sample plots established by independent researchers, some providing data extending back several decades. We will also conduct rapid transect studies of poorly monitored regions. Field expeditions analysed local soil and plant properties in the first phase (2001–2002). Initial results suggest that the network has the potential to reveal much information on the continental-scale relations between forest and environment. The network will also serve as a forum for discussion between researchers, with the aim of standardising sampling techniques and methodologies that will enable Amazonian forests to be monitored in a coherent manner in the coming decades
