Enzymatic grafting of synthetic molecules onto lignins provides a mild and eco-friendly alternative for the functionalization of lignocellulosic materials. In this study, laccase-mediated grafting of octadecylamine (OA) onto lignin-rich jute fabrics was investigated for enhancing the surface hydrophobicity. First, the lignins in jute fabrics were isolated and analyzed in the macromolecular level by MALDI...
Transformation of non-competent Escherichia coli JM109 was accomplished using pUC19 as donor plasmid and sepiolite as the acicular material to promote cell piercing via application of friction with a polystyrene stick or a magnetic bar on the surface of a hydrogel containing agar. An automatic spreading setup was built with a conventional stirring plate and compared to manual spreading. Several parameter...
Hoje em dia as relações entre as organizações e o ambiente são indispensáveis para alcançar um planeta sustentável. É importante para uma organização ter noção do seu impacto ambiental e pegada ecológica no planeta. Assim as organizações procuram cada vez mais melhorar as suas práticas ambientais e tornarem-se mais eficientes. Assim para atingir a excelência e o reconhecimento foram criadas referên...
We use data for a panel of 17 countries over the period 1980-2005 to investigate the impact of fiscal consolidation on the likelihood of financial reforms. We show that fiscal adjustments do not boost the implementation of financial reforms. However, tax-driven fiscal consolidation programs raise the likelihood of banking sector reforms. Moreover, we find that: (i) an increase in the degree of trade open...
