13. Quantificação do estoque de carbono e avaliação econômica de alternativas de uso de um povoamento de eucalipto / Carbon stock quantification and economic evaluation of use alternatives in a eucalyptus stand
This study aimed to quantify wood stock for charcoal and sawmill; biomass stock expressed in carbon tons in the different sectors of a Eucalyptus stand; and to economically evaluate alternatives for inserting forest stands into the Clean Development Mechanisms and carbon credit trade. Thus, a 6 year - old Eucalyptus grandis forest inventory was carried out i

14. Aquecimento global e o mercado de carbono: uma aplicação do modelo CERT. / Global warming and the carbon market: an application of the cert model.
As ações decorrentes das atividades econômicas e industriais têm provocado alterações na biosfera, resultando na quase duplicação da concentração de Gases de Efeito Estufa (GEE) na atmosfera durante o período de 1750 a 1998. A alteração da concentração dos GEE poderá desencadear um aumento da temperatura média no planeta entre 1,4 e 5,8°C n

16. Nitrogen management and the future of food: Lessons from the management of energy and carbon
The food system dominates anthropogenic disruption of the nitrogen cycle by generating excess fixed nitrogen. Excess fixed nitrogen, in various guises, augments the greenhouse effect, diminishes stratospheric ozone, promotes smog, contaminates drinking water, acidifies rain, eutrophies bays and estuaries, and stresses ecosystems. Yet, to date, regulator

17. An in vitro screening technique for DNA polymerases that can incorporate modified nucleotides. Pseudo-thymidine as a substrate for thermostable polymerases.
DNA polymerases are desired that incorporate modified nucleotides into DNA with diminished pausing, premature termination and infidelity. Reported here is a simple in vitro assay to screen for DNA polymerases that accept modified nucleotides based on a set of primer extension reactions. In combination with the scintillation proximity assay (SPA[trade]), this

18. A Regulatory Trade-Off as a Source of Strain Variation in the Species Escherichia coli†
There are few existing indications that strain variation in prokaryotic gene regulation is common or has evolutionary advantage. In this study, we report on isolates of Escherichia coli with distinct ratios of sigma factors (RpoD, σD, or σ70 and RpoS or σS) that affect transcription initiated by RNA polymerase. Both laboratory E. coli K-12 lineages and no

19. Design and characterization of a spatially distributed multibeam field emission x-ray source for stationary digital breast tomosynthesis
Digital breast tomosynthesis (DBT) is a limited angle computed tomography technique that can distinguish tumors from its overlying breast tissues and has potentials for detection of cancers at a smaller size and earlier stage. Current prototype DBT scanners are based on the regular full-field digital mammography systems and require partial isocentric motion
