The system [FeL2](BF4)2 (1)-EtOH-H2O (L is 4-(3,5-dimethyl-1H-pyrazol-1-yl)-2-(pyridin-2-yl)-6-methylpyrimidine) shows a complicated balance between the relative stabilities of solvatomorphs and polymorphs of the complex [FeL2](BF4)2. New solvatomorphs, 1(LS)·EtOH·H2O and β-1(LS)·xH2O, were isolated in this system. They were converted into four daughter phases, 1(A/LS), 1(D/LS), 1(E/LS)·yEtOH·z...

Il seguente articolo si propone di analizzare l’acquisizione delle espressioni idiomatiche nell’apprendimento dell’italiano L2/LS e ipotizzare una possibile attività didattica che permetta indagare questa acquisizione in apprendenti francofoni. Dopo prima sezione teorica cui espone dettagliata analisi questo tipo locuzioni del loro ruolo globale della L2/LS, focalizza l’attenzione sull’analisi ...

Recent observations in our laboratories (1, 2) have demonstrated that a single molecular substance carries all of the serological activity of both the Land Ssoluble antigens of vaccinia. Craigie and Wishart, (3) who originally described these two antigens thought that they occurred in the form of a complex in nature, but, from their own observations (3) and from those of Parker (4), they were l...

We previously showed oxidative damage and edema within skeletal muscle after contractile claudication. To investigate the sources of this oxidative damage in the gastrocnemius muscle, we administered allopurinol (Allo, to inhibit xanthine oxidase) and cyclophosphamide (Cyclo, to deplete neutrophils) before inducing contractile claudication in male Sprague Dawley rats. Contractile claudication (...

Strong turbulence causes phase discontinuities known as branch points in an optical field. These discontinuities complicate the phase unwrapping necessary to apply phase corrections onto a deformable mirror in an adaptive optics (AO) system. This paper proposes a non-optimal but effective and implementable phase unwrapping method for optical fields containing branch points. This method first ap...
