Sustainable Development, EarlyView.ABSTRACT Climate mitigation policies in the Brazilian Legal Amazon have largely focused on aggregate or net emissions, providing limited evidence on how gross agricultural emissions reveal the intensity of productive emission sources independently of carbon removals.

32P-postlabelling analysis of complex DNA adducts in human tissues
, 1998 Complex DNA adducts in humans originate from exogenous and endogenous sources. Polycyclic aromatic hydrocarbons (PAHs) are a large group of chemicals including many potent carcinogens.

Ligand binding represses bacterial histidine kinase activity by inhibiting its dimerization
The FEBS Journal, EarlyView.PdtaS is a kinase in the pathogen Mycobacterium tuberculosis that senses copper and nitric oxide and controls virulence gene expression, but how the kinase senses these compounds was unclear. We show that PdtaS is active as a dimer with each monomer phosphorylating the other in trans.

Dose Assessment of Phosphorus-32 (32P) for the Treatment of Recurrent Pterygium [PDF]
Iranian Journal of Medical Physics, 2014 Introduction Pterygium is a wing-shaped, vascular, fleshy growth that originates from the conjunctiva and can spread into the corneal limbus and beyond.

Ploidy‐dependent modulation of DNA replication kinetics in Xenopus
The FEBS Journal, EarlyView.Using an interspecies replication system with Xenopus frog species of different ploidy levels, we investigated how DNA replication adapts to polyploidization. While replication was slower in tetraploid than in diploid nuclei, dodecaploid nuclei unexpectedly replicated faster than tetraploid nuclei. Our findings show that increasing genome size does not

Revista Brasileira de Zootecnia, 1999 Esta pesquisa foi realizada para estudar a cinética do fósforo (P) em tecidos de suínos em crescimento, alimentados com rações contendo níveis crescentes de P total (0,30; 0,40; 0,51; 0,65; e 0,73%), por meio do uso do 32P como traçador.

Inference via the Skewness‐Kurtosis Set
International Statistical Review, EarlyView.Summary Kurtosis minus squared skewness is bounded from below by 1, but for unimodal distributions, this parameter is bounded by 189/125. In some applications, it is natural to compare distributions by comparing their kurtosis‐minus‐squared‐skewness parameters. The asymptotic behavior of the empirical version of this parameter is studied here for i.i.d.

Exchange of Radioactive Phosphorus 32P between the Components of an Artificial Plant Community
Acta Societatis Botanicorum Poloniae, 2015 In artificial plant communities (wooden cases with soil) the following plants were grown together for one year: case No. 1: Betula verrucosa Ehrh. (2 specimens) and Carex pilosa Scop.; sases No.

Molecular Microbiology, EarlyView.Low basal activity of divergent promoters driving transcription of the trimethylamine N‐oxide (TMAO) sensor TorT and kinase TorS is integral to an O2‐regulated bet‐hedging strategy for continued E. coli growth upon the onset of anaerobiosis. This, along with repression by IscR, promotes noise in the TorS to TorT ratio, which is critical for adaptation ...
