RESUMEN: El autor defiende, en el presente articulo, que el origen de la imagen del caracol que aparece en la empresa numero 60 de las Empresas Morales de Juan de Borja posee un origen escrito y que puede rastrearse hasta la Picta Poesis de Aneau Barthelemy. PALABRAS CLAVES: Origen, Caracol, Empresa, Empresas Morales , Juan de Borja, Picta Poesis, Aneau Barthelemy.

Motivi tragici nelle Imagines di Filostrato Maggiore (I 4; 18; 27; II 4; 10; 13; 23; 29; 30).

Grazie all'analisi del rapporto tra il testo delle descrizioni di Filostrato e quello di Seneca tragico, Ovidio e Stazio si ipotizza la presenza nelle Imagines di allusioni ad opere ellenistiche perdute (si fa riferimento a Callimaco e Nicandro) . Inoltre, sulla base di un parallelismo tra II 4 (Ippolito) e un verso delle Rane di Aristofane si rintraccia una citazione dell'Ippolito Velato euripideo. The analysis of the relationship between the Philostratean text and the one of Seneca (only Tragedies), Ovid and Statius confirmed the presence in Philostratus' Imagines of allusions to some Hellenistic lost works (we refer to Callimachus and Nicander) . In addition, thanks to a parallel between…

A Low Cost Solution for 2D Memory Access

2006

Many of the new coding tools in the H.264/AVC video coding standard are based on 2D processing resulting in row-wise and column-wise memory accesses starting from arbitrary memory locations. This paper proposes a low cost solution for efficient realization of these 2D block memory accesses on sub-word parallel processors. It is based on the use of simple register-based data permutation networks placed between the processor and memory. The data rearrangement capabilities of the networks can further be extended with more complex control schemes. With the proposed control schemes, the networks enable row and column accesses from arbitrary memory locations for blocks of data while maintaining f…

Material properties of various intraocular lenses in an experimental study.

2002

<i>Introduction:</i> With the recent introduction of small-incision cataract surgery, requirements for intraocular lens (IOL) flexibility, strength and hydrophilicity have rapidly evolved. The IOL surface, however, remains a critical factor influencing uveal biocompatibility. <i>Purpose:</i> To objectively quantify factors of material properties of various IOLs using contact angle measurements, differential scanning calorimetry, dynamic-mechanical measurements and scanning electron microscopy. <i>Material and Methods:</i> In our study, 17 currently available IOLs were investigated using contact angle measurements to assess hydrophilicity and biocompatibil…

Effect of a fluctuating electric field on electron spin dephasing in III-V semiconductors

2011

In the present work we investigate electron spin relaxation in low-doped n-type GaAs semiconductor bulks driven by a static electric field. The electron dynamics is simulated by a Monte Carlo procedure which keeps into account all the possible scattering phenomena of the hot electrons in the medium and includes the evolution of spin polarization. Spin relaxation lengths are computed through the D’yakonov-Perel process, which is the only relevant relaxation mechanism in zinc-blende semiconductors. Since semiconductor based devices are always imbedded into a noisy environment that can strongly affect their performance, the decay of initial spin polarization of conduction electrons is calculat…

18F-labeling of peptides by means of an organosilicon-based fluoride acceptor.

2006

Fluorine-18 is among the most commonly used radionuclides for positron emission tomography (PET). This non-invasive imaging technique is capable of providing in vivo information about the distribution of radiolabeled biomolecules by 1808 coincidence detection of two simultaneously emitted photons from positron–electron annihilation. Although a number of different radiotracers have been successfully employed in PET, only a few, such as 2-[F]fluoro-2-deoxy-d-glucose (FDG) and [F]fluorodopa, have gained widespread application in nuclear medicine. The reason for this is that the regioselective introduction of F into tracer molecules is often non-specific and radiochemical yields (RCY) of the Fl…

Interaction-induced spin polarization in quantum dots.

2010

The electronic states of lateral many electron quantum dots in high magnetic fields are analyzed in terms of energy and spin. In a regime with two Landau levels in the dot, several Coulomb blockade peaks are measured. A zig-zag pattern is found as it is known from the Fock-Darwin spectrum. However, only data from Landau level 0 show the typical spin-induced bimodality, whereas features from Landau level 1 cannot be explained with the Fock-Darwin picture. Instead, by including the interaction effects within spin-density-functional theory a good agreement between experiment and theory is obtained. The absence of bimodality on Landau level 1 is found to be due to strong spin polarization.

The evolution of the local role(s) of the university in a low-tech region

2013

The present case study addresses the case of a geographical area neglected by most of the literature about the changing role of Higher Education Institutions (HEIs): the low-tech contexts. This literature has traditionally exhibited two primary aspects. First, a focus on success stories such as entrepreneurial universities located in high-tech regions (e.g. Silicon Valley). Second, it reveals an inclination towards an evolution from ivory towers to entrepreneurial universities. The article argues that this oversimplification does not apply exactly to some environments where the HEIs have maintained links with industry since their inception. The purpose is to demonstrate HEIs' relevance in l…

Un enigma architettonico tra storia, disegno e ricostruzioni: la chiesa di San Nicolò alla Kalsa a Palermo

2022

Il contributo affronta lo studio di un monumento scomparso della città di Palermo, la chiesa parrocchiale di San Nicolò alla Kalsa, che aveva rivestito un ruolo significativo nel contesto urbano medievale e della prima età moderna, conoscendo successivamente un progressivo abbandono e degrado fino alla sua demolizione dopo il 1823, e ne propone una ricostruzione virtuale attraverso l’elaborazione di un modello 3D. Strumento principale per la conoscenza dell’edificio scomparso è un’articolata iconografia storica, che spazia dalla scala urbana a quella del dettaglio architettonico, qui vagliata per desumerne dati necessari alla formulazione di un’ipotesi ricostruttiva attendibile e scientific…

Analysis of artificially degraded DNA using STRs and SNPs—results of a collaborative European (EDNAP) exercise

2005

Recently, there has been much debate about what kinds of genetic markers should be implemented as new core loci that constitute national DNA databases. The choices lie between conventional STRs, ranging in size from 100 to 450 bp; mini-STRs, with amplicon sizes less than 200 bp; and single nucleotide polymorphisms (SNPs). There is general agreement by the European DNA Profiling Group (EDNAP) and the European Network of Forensic Science Institutes (ENFSI) that the reason to implement new markers is to increase the chance of amplifying highly degraded DNA rather than to increase the discriminating power of the current techniques. A collaborative study between nine European and US laboratories…
