ABSTRACT After performing the morpho-kinematic analysis of planetary nebula (PN) PC 22, we now present its nebular and stellar analysis. The plasma investigation relies on novel use a Monte Carlo associated with pyneb code for uncertainty propagation. innermost region shows electronic temperatures Te ≈ 10 800 K using [N ii] ≈13 000 [O iii] densities ne 600 cm−3. We also used first time machine ...

RESUMO As mudanças climáticas podem causar alterações drásticas nos ecossistemas lacustres especialmente em razão da elevação temperatura e das na precipitação, provocando, entre outros fatores, aumento no aporte de nutrientes e, consequentemente, eutrofização. Este trabalho apresenta a estimativa projeções vazão carga (NO3−, PO4–3) afluentes à lagoa Mangueira — grande rasa subtropical localiza...

Climate projections for the fourth assessment report1 (AR4) of the Intergovernmental Panel on Climate Change (IPCC) were based on scenarios from the Special Report on Emissions Scenarios2 (SRES) and simulations of the third phase of the Coupled Model Intercomparison Project3 (CMIP3). Since then, a new set of four scenarios (the representative concentration pathways or RCPs) was designed4. Clima...

The inhibitory neuropeptide somatostatin (SRIF) initiates many of its physiological effects by binding to membrane receptors which are coupled to pertussis toxin-sensitive G-protein(s). We have solubilized such a SRIF receptor-G-protein complex and purified it using a biotinylated SRIF analog and guanine nucleotide-dependent affinity chromatography. Following [125I-Tyr11]SRIF binding to membran...

Intercomparisons of coupled atmosphere-ocean general circulation models (AOGCMs) and carbon cycle models are important for galvanizing our current scientific knowledge to project future climate. Interpreting such intercomparisons faces major challenges, not least because different models have been forced with different sets of forcing agents. Here, we show how an emulation approach with MAGICC6...
