Bioactivity of Piper extracts on Tuta absoluta (Lepidoptera: Gelechiidae) in tomato
(Empresa Brasil Pesq Agropec, 2015-03-01)
The objective of this work was to evaluate the bioactivity of ethanolic leaf extracts from four species of the genus Piper against the tomato leafminer Tuta absoluta (Lepidoptera: Gelechiidae) under laboratory conditions. ...
4-amine-2-mercaptopyrimidine modified silica gel applied in Cd(II) and Pb(II) extraction from an aqueous medium
(Versita, 2010-01-01)
This paper discusses silica surface modification by a process involving a two-step reaction: anchoring of a silylating agent, followed by an attachment of a 4-amino-2-mercaptopyrimidine molecule. The modified material ...

Comparison of oxygen mass transfer coefficient in simple and extractive fermentation systems
(ELSEVIER SCIENCE SA, 2009)
Aeration and agitation are important variables to ensure effective oxygen transfer rate during aerobic bioprocesses: therefore, the knowledge of the volumetric mass transfer coefficient (k(L)a) is required. In view of ...
