This paper analyzes the impact of instability brought about by change directors on risk corporate debt default from perspective fusion old and new directors. Combining Ab-sorptive Capacity Theory Embeddedness Theory, one hand, threshold effect hard integration proportion directors; other through number well-integrated people, ability-based role matching cultural-based group between directors, i...

Chemical phosphorus removal in wastewater treatment plants can be carried out by precipitation with iron or aluminum salts filtering through a bed of active sorptive material. This work aimed to investigate whether using meander flow filter filled the sorption material Rockfos® would improve efficiency selected plant. Tests were performed under laboratory conditions model and similar field at f...

Four Semi-Interpenetrating Networks (semi-IPN) based on polydimethylsiloxane (PDMS) were developed for the sorptive extraction of polar phenolic compounds (log Kow ≤ 3). Their preparation is hydrosilylation crosslinking reaction dihydrosilane terminated with its homologue divinyl, followed by addition inert various polyethylene oxide derivatives (PEO). The physico-chemical properties semi-IPN c...

The present study was carried out to investigate the potential of basidiomycete Auriporia aurulenta metabolize residues remaining from processing umbu, cajá, plum, and persimmon fruits for production natural aroma compounds using submerged fermentation. volatile obtained fermentation A. cultivated in these were extracted via stir bar sorptive extraction (SBSE) analyzed a gas chromatography-mass...
