RESISTĂNCIA Ă PENETRAĂĂO E DENSIDADE DO SOLO COMO INDICADORES NA ANĂLISE DA SUSCEPTIBILIDADE A EROSĂO HĂDRICA DOS SOLOS
O presente trabalho teve como objetivo avaliar os solos argilosos SOB diferentes tipos de uso no que tange a resistĂȘncia a penetração e densidade do solos, considerando que as modificaçÔes nas condiçÔes fĂsicas influenciam nas condiçÔes de infiltração e nos processos erosivos. Os valores de RP nas ĂĄreas com cana-de- açĂșcar foram superiores aos valores nas ĂĄreas com pastagens. Todas as curvas de RP referente aos solos argilosos apresentaram valores superiores aos limites indicados na bibliografia
Internal representations of smell in the Drosophila brain
Recent advances in sensory neuroscience using Drosophila olfaction as a model system have revealed brain maps representing the external world. Once we understand how the brain's built-in capability generates the internal olfactory maps, we can then elaborate how the brain computes and makes decision to elicit complex behaviors. Here, we review current progress in mapping Drosophila olfactory circuits and discuss their relationships with innate olfactory behaviors
CyanoFactory, a European consortium to develop technologies needed to advance cyanobacteria as chassis for production of chemicals and fuels
CyanoFactory, Design, construction and demonstration of solar biofuel production using novel (photo)synthetic cell factories, was an R&D project developed in response to the European Commission FP7-ENERGY-2012-1 call âFuture Emerging Technologiesâ and the need for significant advances in both new science and technologies to convert solar energy into a fuel. CyanoFactory was an example of âpurpose drivenâ research and development with identified scientific goals and creation of new technologies. The present overview highlights significant outcomes of the project, three years after its successful completion.
The scientific progress of CyanoFactory involved: (i) development of a ToolBox for cyanobacterial synthetic biology; (ii) construction of DataWarehouse/Bioinformatics web-based capacities and functions; (iii) improvement of chassis growth, functionality and robustness; (iv) introduction of custom designed genetic constructs into cyanobacteria, (v) improvement of photosynthetic efficiency towards hydrogen production; (vi) biosafety mechanisms; (vii) analyses of the designed cyanobacterial cells to identify bottlenecks with suggestions on further improvements; (viii) metabolic modelling of engineered cells; (ix) development of an efficient laboratory scale photobioreactor unit; and (x) the assembly and experimental performance assessment of a larger (1350âŻL) outdoor flat panel photobioreactor system during two seasons.
CyanoFactory - Custom design and purpose construction of microbial cells for the production of desired products using synthetic biology â aimed to go beyond conventional paths to pursue innovative and high impact goals. CyanoFactory brought together ten leading European partners (universities, research organizations and enterprises) with a common goal â to develop the future technologies in Synthetic biology and Advanced photobioreactors

Spin alignment of leading mesons in hadronic decays
Helicity density matrix elements for inclusive K*(892)^0 mesons from hadronic Z^0 decays have been measured over the full range of K^*0 momentum using data taken with the OPAL experiment at LEP. A preference for occupation of the helicity zero state is observed at all scaled momentum x_p values above 0.3, with the matrix element rho_00 rising to 0.66 +/- 0.11 for x_p > 0.7. The values of the real part of the off-diagonal element rho_1-1 are negative at large x_p, with a weighted average value of -0.09 +/- 0.03 for x_p > 0.3, in agreement with new theoretical predictions based on Standard Model parameters and coherent fragmentation of the qq(bar) system from the Z^0 decay. All other helicity density matrix elements measured are consistent with zero over the entire x_p range. The K^*0 fragmentation function has also been measured and the total rate determined to be 0.74 +/- 0.02 +/- 0.02 K*(892)^0 mesons per hadronic Z^0 decay.Helicity density matrix elements for inclusive K*(892)^0 mesons from hadronic Z^0 decays have been measured over the full range of K^*0 momentum using data taken with the OPAL experiment at LEP.
