UNA CROCE SCOLPITA DI GIACOMO PIAZZETTA
No full textUna croce scolpita (legno di bosso, alt. 107 cm), si trova appesa al muro della chiesa di S. Pietro a Cittavecchia (Stari Grad, isola di Hvar); nella stessa chiesa dunque nella quale, alcuni anni fa, scoprii »Pietà« del Tintoretto. Si tratta di un valente artista, di Giacomo Piazzetta. Si tratta, inoltre, del padre e del primo maestro del grande Gian Battista. La nostra croce porta anche la firma: sulla parte destra del perizoma leggiamo: OPs IAs Piazzetta.
Dell’autenticità della firma non si può dubitare nonostante il fatto che essa sia incisa vicino al nome del donatore: N.D. Budrovich D.D. 1847; i caratteri però ed il modo di incidere sono diversi. Nikola Domenik Budrović aveva dunque legato nel 1847 questa croce al convento dei domenicani a Stari Grad. Ma sula parte oposta del perizoma troviamo inciso il terzo nome: P. M. D. Scutari F. F. 1703. Qui, evidentemente, è indicata la data di nascita di questa opera di Giacomo, fatto importante per la cronologia del suo »opus«. Due anni prima di morire lo scultore scolpi quindi questa croce che, nella maniera e nella maestria di esecuzione, non si differenzia molto dai dossali che oggi si trovano nella cappella del Rosario dela chiesa di SS. Giovanni e Paolo.
Pare veramente che con la croce di Stari Grad ci troviamo nello stesso tempo e nell’ambito dello stile dei dossali di SS. Giovanni e Paolo.
Il legame della figura del nostro Crocifisso con i Telamoni di questi dossali è strettissimo. Siamo all’apice dell’ evoluzione di Piazetta, e proprio su uno di questi dossali si trova il telamone la cui modellazione dimostra le caratteristiche e perfino delle parti quesi identiche a quelle del Cristo. Quando scolpi la nostra croce, Piazzetta aveva raggiunto 62 anni di vita, e la sua arte, nonostante lavorasse quesi esclusivamente in legno, rappresentava nella scultura veneziana una sorta di simbiosi della corrente lecourtiana con quella chi possiamo chiamare roccocò.
Naturalmente, in sacro soggetto imponeva all’artista una certa »invenzione« convenzionale che non gli permise un particolare impeto dell’immaginazione creative. Piazzetta scolpi il suo Crocifisso in base alla nota invenzione barocca usata dagli scultori del tempo; così, per esempio, da Enrico Merengo nella Chiesa delle Eremite. Ma la maniera dell’esecuzione è assolutamente sua. La viva modellazione, particolarmente quella delle parti del ventre, è completata da un forte drappeggiare del parizoma, pittorico e »stilizzato« nello stesso tempo, ma anche tipicamente barocco
The turbulent dissipation rate from PIV measurements
No full textThe result of a particle-image velocimetry (PIV) measurement is a velocity field averaged over interrogation windows. This severely affects the measurement of small-scale turbulence quantities when the interrogation window size is much larger than the smallest length scale in turbulence. A direct measurement of the dissipation rate demands the measurement of gradients of the velocity field, which are now underestimated because the small-scale motion is not resolved. A popular procedure is to relate the statistical properties of the measured, but underresolved gradients to those of the true ones, invoking a large-eddy argument [3]. We show that the used proportionality constant, the Smagorinsky constant, should depend on the window overlap, on the used elements of the strain tensor, and on the way in which derivatives are approximate
How the dispersion of a droplet cloud depends on its initial size
No full textA cloud of droplets evolves under the influence of strong turbulence. The droplets are made from a phosphorescent fluid. From this cloud we select at t = 0 a narrow line by exciting the droplets with a UV laser, which causes them to glow for a few milliseconds. The dispersion of this line is followed in time using a fast intensified camera. A large range of droplet sizes (Stokes number St) was measured. It appears that lines with St \approx 1 disperse faster than a line of fluid tracers. Lines of droplets which are narrowest initially, spread fastest

On fully nonlinear CR invariant equations on the Heisenberg group
No full textAbstractIn this paper we provide a characterization of second order fully nonlinear CR invariant equations on the Heisenberg group, which is the analogue in the CR setting of the result proved in the Euclidean setting by A. Li and the first author in Li and Li (2003) [21]. We also prove a comparison principle for solutions of second order fully nonlinear CR invariant equations defined on bounded domains of the Heisenberg group and a comparison principle for solutions of a family of second order fully nonlinear equations on a punctured ball

The Potentials of Recommender Systems Challenges for Student Learning
No full textIncreasingly, educators make use of learning-by-doing approaches to teach students
of STEM programmes the skills that they need to become successful in
careers in research and development. However, we argue that the technical
challenges addressed in these programmes are often too limited and therefore
do not support the students in gaining the more advanced skill sets required to
thrive in our technology-oriented economy. We therefore suggest to incorporate
realistic and complex challenges that model real-world problems faced in
industrial settings. Focusing on the domain of recommender systems, we see
potentials in embedding recommender systems challenges to enhance student
learning to teach students the skills required by modern data scientists
Analysis of sustainability in business of the company NEXE d.d.
No full textUlaskom Republike Hrvatske u Europsku Uniju održivo poslovanje postaje sve značajnije, ali i krucijalno za daljnji razvoj gospodarstva i poslovanja poduzeća. Osim regulativnog značaja, posebnu pažnju održivom poslovanju pružaju razni stakeholderi i investitori, odnosno shareholderi. Razlog navedenom očita se u činjenici kako se poslovanje reflektira ne samo kroz različite indikatore performansi koherentnima financijskim pokazateljima, već i u problematici poslovanja svedenih i na nefinancijske pokazatelje nužnima za nastavak nevolatilnog poslovanja (ljudski kapital, proizvodni procesi i tehnologije, organizacijska kultura, briga za okoliš itd.). Koncept održivog poslovanja, iako s bogatom poviješću, konkretnije započinje 1987. godine kada je u izvješću Our Common Future (Brundtland, 1987.) univerzaliziran te doživljava konstantne preinake i modifikacije, posebno u posljednjem desetljeću kada važnost koncepta raste zbog alarmantnih podataka praktički vezanih uz opstanak ljudske vrste, ali i preusmjerava na konkurentsku prednost poduzeća. Stoga, autor ovog rada će stvoriti jedinstveni okvir koji omogućuje analizu održivosti poslovanja poduzeća i analizirati proces adaptacije održivosti poduzeća NEXE d.d. kao predstavnika industrije građevinskog materijala u Republici Hrvatskoj. Rad se primarno bazira na kvalitativnim podacima dobivenim kroz prikupljenu međunarodnu literaturu visokog kredibiliteta, akademskim člancima i drugim komplementarnim izvorima te službenim dokumentima poduzeća NEXE d.d.With the accession of the Republic of Croatia to the European Union, sustainability in business becomes increasingly important, but also crucial for the further development of the economy and business operations. Apropos of regulatory importance, special attention is paid to sustainable business by various stakeholders and investors, i.e. shareholders. The reason for the above can be seen in the fact that business is reflected not only through the lens of various performance indicators coherent with financial indicators, but also in the issue of business reduced to non-financial indicators necessary for the continuation of non-volatile business (human capital, production processes & technologies, organizational culture, care for the environment, etc.). The concept of sustainable business, although with a rich history, more concretely begins in 1987. when it was universalized in the report Our Common Future (Brundtland, 1987.) and it experienced constant changes and modifications, especially in the last decade when the importance of the concept grew due to alarming data practically related to the survival of human species, but it also got redirected as a competitive advantage of the company. Therefore, the author of this study will create a unique framework that enables the analysis of a company's operations sustainability and the analysis of the process of adaptation to the sustainability of the company NEXE d.d. as a representative of the construction material industry in the Republic of Croatia. The study is primarily based on qualitative data obtained through collected international literature of high credibility, academic articles and other complementary sources and official documents of the company NEXE d.d.
