Molecularly imprinted polymer solid phase extraction of fungicides from wine samples
2014
In order to preconcentrate iprodione fungicide in white wine samples, molecularly imprinted polymers (MIPs) specific for iprodione were synthesized using two polymerization approaches: precipitation (MIPp) and bulk polymerization (MIPb). A comparison of the performance of the MIPs and the corresponding non-imprinted polymers (NIPs) was conducted in batch studies. In this case, the MIPp revealed better recognition properties toward iprodione in wine samples than the MIPb. The MIPp and MIPb were then used as sorbents on solid phase extraction cartridges (MISPEp and MISPEb consecutively) in order to pre-concentrate iprodione from white wine samples. The optimization of the MISPE elution step w…

Binding characteristics of molecularly imprinted polymers based on fungicides in hydroalcoholic media
2015
An iprodione-imprinted polymer was prepared by copolymerization of methacrylamide and ethylene glycol dimethacrylate using a noncovalent imprinting approach. Methacrylamide was chosen using molecular dynamics simulations. To concentrate iprodione from hydro-alcoholic solutions, batch sorption of iprodione on the imprinted polymer were conducted. The equilibrium time for iprodione sorption is 20 min, and the corresponding kinetic mechanism follows the pseudo-second order indicating a strong interaction between iprodione and the imprinted polymer. Langmuir, Freundlich, and Dubinin-Radushkevich models were used to fit the isotherm of iprodione sorption. The imprinted polymer was found to be mo…
Experimental design approach in the synthesis of molecularly imprinted polymers specific for iprodione fungicide
2015
International audience; An experimental design (ED) approach was applied to study the weight of three factors in the synthesis of a molecularly imprinted polymer (MIP) specific for iprodione fungicide. The objective was to obtain a high specific polymer with the best performance of iprodione binding. Thirteen iprodione-imprinted polymers and 13 non-imprinted polymers (NIP) were synthesized according to ED having 3 influencing factors: the polymerization method, the crosslinker nature and the functional monomer type. For each factor, two levels were studied: bulk and precipitation polymerization for the first factor, trimethylolpropane trimethacrylate (TRIM) and ethylene glycol dimethacrylat…
A Derrota da Esquerda como a Direita Gosta
2001
Itália. Abril de 1996. Facto histórico. O antigo maior partido comunista do Ocidente, aliado à pequenas agregações centristas, vence as eleições nacionais, depois de passar 50 anos à margem da gestão do Estado, devido ao veto ianque, da Igreja e do capital, apesar de contar com cerca de 30% do eleitorado. O Partido da Refundação Comunista, que nascera em 1991, quando o PCI mudara de nome para Partido dos Democratas de Esquerda [PDS], assumindo-se social-democrata, apoiara, de fora, a coligação. O PRC formara-se com operários, Estalinistas, maoistas, sindicalistas, trotskistas, etc. que se haviam negado a terminar a luta anti-capitalista. Nem mesmo no horizonte político, a coligação do Ulivo…
Nascere diversi nell’antica Roma
2014
The analysis is mainly concerned with the condition of infants, in particular the problem of neonatal deformity in ancient Rome. The incidence of deformed births must have been considerable, if tradition records specific provisions on the exposure of deformed infants as far back as royal times. From the narratives of the historians, it can be deduced that deformity greatly impressed the ancient Romans, who were very superstitious in this regard, as can be seen from the very terminology used (monstrum, portentum, ostentum, prodigium etc.). The entity of the deformity thus became a discriminating factor for the very purpose of considering the child born as belonging to the human species, an e…
