A mass spectrometry approach to dairy science
No full textBovine milk is a source of an array of (un)known (bioactive) compounds from a variety of molecular and chemical classes. Because of a such complex food matrix, accurate and sensitive analytical approaches are needed to identify newly formed molecules (e.g. bioactive milk non-nutrients or xenobiotics), to recognize chemical and enzymatic modifications which known milk components undergo upon processing, storage and in vitro digestion. In this perspective, tailored sample preparation followed by liquid chromatography/high resolution mass spectrometry (LC/HR-MS) represents a powerful analytical tool to solve some scientific issues in dairy sector. In this presentation, some of the current applications of MS in dairy science will be discussed with special regard to characterization of novel functional/(bio)active milk compounds [1], reliable identification of dairy markers (e.g. studying post-translational modifications [2], proteolytic phenomena [3–6], identification of bioactive non-nutrients [7–9]), traceability and confirmation of authenticity [10] of dairy products.

Lo sviluppo del territorio come chiave del progresso civile: suggestioni da Cattaneo
No full textLe riflessioni di Cattaneo sullo sviluppo sono inquadrate nell’ambito della questione relativa all’apporto del positivismo allo strutturarsi dell’economia politica come scienza.
Il positivismo presente in Cattaneo viene riconnesso alla fiducia che gli economisti lombardi da Verri a Beccaria a Romagnosi a Gioia mostrano di avere nell’industrialismo e nel progresso tecnico, fiducia che sanno declinare in una cultura di sviluppo economico e insieme sociale e civile. Nei suoi scritti sul tema Cattaneo da un lato esalta l’importanza dell’economia, dall’altro
nel pretendere che la stessa abbia una solida base scientifica, la lega in modo indissolubile alle
problematiche civili dello sviluppo, come se l’economia potesse avere in effetti un ruolo «rigenerante» per la società civil

Incontri alla fine del mondo. Conversazioni tra cinema e vita
No full textEdizione italiana a cura di Francesco Cattaneo del libro "Herzog on Herzog" di Werner Herzog a a cura di Paul Cronin, Faber&Faber, London, 2002. L'intervista di Paul Cronin si sofferma su tutti gli aspetti rilevanti della vita e dell'opera del regista cinematografico Werner Herzog, con considerazioni che spaziano dalla storia tedesca ai problemi del nostro tempo, dall'estetica del cinema alla filosofia
Cloning and expression of an anti-nerve growth factor (NGF) antibody for studies using the neuroantibody approach
No full text1. The neuroantibody approach, based on the expression of selected monoclonal antibodies by cells of the nervous system, has recently been described (Cattaneo and Neuberger, 1987; Piccioli et al., 1991). In order to apply this experimental strategy to study the role of nerve growth factor (NGF) in the central nervous system (CNS), we exploited the monoclonal antibody (mAb), alpha D11, which neutralizes very efficiently the biological activity of NGF, both in vitro and in vivo (Cattaneo et al., 1988). 2. The alpha D11 antibody chains were cloned and expressed in COS cells as rat/human chimaeric proteins. The cloned antibody was shown to display all the properties of the parental alpha D11 antibody, including its ability to neutralize NGF biological activity. 3. This will allow us to engineer the expression of recombinant alpha D11 antibodies in the CNS, to study the role of NGF in the developing and adult nervous system. This approach can be extended to other neurotrophic factors for which neutralizing monoclonal antibodies are available

Shear-Driven Dynamo Waves in the Fully Nonlinear Regime
No full textLarge-scale dynamo action is well understood when the magnetic Reynolds number (Rm) is small, but becomes problematic in the astrophysically relevant large Rm limit since the fluctuations may control the operation of the dynamo, obscuring the large-scale behavior. Recent works by Tobias & Cattaneo demonstrated numerically the existence of large-scale dynamo action in the form of dynamo waves driven by strongly helical turbulence and shear. Their calculations were carried out in the kinematic regime in which the back-reaction of the Lorentz force on the flow is neglected. Here, we have undertaken a systematic extension of their work to the fully nonlinear regime. Helical turbulence and large-scale shear are produced self-consistently by prescribing body forces that, in the kinematic regime, drive flows that resemble the original velocity used by Tobias & Cattaneo. We have found four different solution types in the nonlinear regime for various ratios of the fluctuating velocity to the shear and Reynolds numbers. Some of the solutions are in the form of propagating waves. Some solutions show large-scale helical magnetic structure. Both waves and structures are permanent only when the kinetic helicity is non-zero on average
"Ma il sapere è molto più debole della necessità". L'essere umano alla prova della sovrabbondanza dell'Essere
No full textIl contributo si propone di discutere la lettura di Heidegger proposta da Richard Capobianco. In particolare, si sofferma sul primato dell'Essere, la sua relazione con la finitezza del pensiero umano e con il divino, il ruolo dell'inutile, la natura originaria, la comprensione della tecnica e infine la lettura della filosofia di Heidegger in chiave trascendentale e pragmatica. Il contributo tenta di affrontare in chiave fenomenonologico-ermeneutica una serie di motivi centrali del pensiero heideggeriano dell'Essere e di mostrarne le interconnessioni. Le riflessioni sulla finitezza del pensiero (in termini non kantiani), sul divino e sull'inutile si prospettano come un apporto originale alla Heidegger-Forschung
Buoyancy driven convection with a Cattaneo flux model
No full textWe review models for convective motion which have a flux law of Cattaneo type. This includes thermal convection where the heat flux law is a Cattaneo one. We additionally analyse models where the convective motion is due to a density gradient caused by a concentration of solute. The usual Fick's law in this case is replaced by a Cattaneo one involving the flux of solute and the concentration gradient. Other effects such as rotation, the presence of a magnetic field, Guyer-Krumhansl terms, or Kelvin-Voigt theories are briefly introduced
