The Xanthomonas citri Hanks‐type kinase PknS autophosphorylates and directly phosphorylates the alternative sigma factor EcfK at five residues. Besides the conserved residue T51 in the σ2 domain, phosphorylation of a residue in the linker between σ2 and σ4 is critical for EcfK activation by promoting its interaction with a positively charged pocket in ...

Despite severe habitat loss, insect species richness, seasonal fluctuations in richness and temporal β‐diversity did not differ significantly among forests adjacent to the mudflow and reference sites. We found higher wet‐season species richness for ants, bees, butterflies and dung beetles, while termites showed no seasonal change; β‐diversity was ...

ABSTRACT Polymeric blends (PB) represent a rapid and cost‐effective strategy for the development of materials with tailored properties. In this study, blends of polystyrene (PS) and poly(o‐methoxyaniline) (POMA) containing 7.5 wt/wt% of POMA were prepared and hybridized with erbium oxide (Er2O3) at concentrations of 0.5, 1.0, and 3.0 wt/wt%.

GelMA/DMAEMA hybrid hydrogels for release of ibuprofen. ABSTRACT In this study, biocompatible hydrogels intended for topical delivery of ibuprofen were synthesized from gelatin methacryloyl (GelMA) and 2‐(dimethylamino)ethyl methacrylate (DMAEMA) by varying their proportions. The impact of different GelMA and DMAEMA ratios was comprehensively evaluated

Engenharia geotécnica: Alicerce fundamental de todas as engenharias
A Engenharia Geotécnica é apresentada como a base imprescindível sobre a qual se apoiam todas as obras de engenharia. Este artigo discute a importância dessa área, destacando que todas as construções dependem intrinsecamente do terreno em que se inserem, o que torna fundamental o conhecimento aprofundado do solo, das rochas e da água subterrânea para ...
