Il Vaticano e la chiesa, il governo colombiano, il conte Chigi Saracini: committenze prestigiose sotto il segno della tradizione
No full textDalla Maremma a Siena, via Roma e Bogotá: un itinerario biografico
No full textIl testo ripercorre l'opera di Vico Consorti attraverso i diversi luoghi e contesti in cui si è sviluppata: dalla natia Maremma alla formazione senese tra simbolismo e tardoliberty, dalla maturità artistica raggiunta a Roma negli anni Trenta, che vede lo scultore impegnato in diversi cantieri promossi dal regime (dalla stessa capitale a Napoli, Livorno, Siena), alla prestigiosa committenza vaticana nel dopoguerra, dal lungo periodo trascorso in Colombia negli anni Cinquanta fino al definitivo rientro a Siena

Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Design of bioreactor based on immobilized laccase on silica-chitosan support for phenol removal in continuous mode
Full text linkA silica-chitosan support was employed for laccase immobilization. The hybrid support was obtained using calcium ion as linking agent that coordinates silanol and hydroxyl groups of chitosan. The insoluble biocatalyst was then packed in a column and used in a flow system for phenol removal. The immobilized enzyme reactor (IMER) showed a good storage stability (70 % of activity in 70 days) and good reusability (90−50 % of catalytic activity at the 4th reuse in function of chitosan type). The best performance for the phenol removal was obtained with a low molecular weight chitosan from crab shells at pH 5 and with a flow rate of 0.7 mL/min. The apparent Michaelis–Menten (Vmaxapp, Kmapp) and the inherent (Vmaxinh, Kminh) constants were also determined to evaluate the influence of the phenol structure on the performance of the system. The enzymatic oxidation of a phenol mixture (4-methylcatechol, catechol, caffeic acid, syringic acid, vanillic acid, p-coumaric acid, and tyrosol) was followed for 21 h in a continuous mode by HPLC. The phenol mixture removal of 90 % was also confirmed by Folin‐Ciocalteu assay
