"Venezia Bella regina maris": Aman-Jean vs Moreau secondo Lorrain
No full textIl saggio si apre con la critica velenosa di Jean Lorrain a "Venezia bella regina maris", un dipinto ad olio di Aman-Jean esposto al Salon de la Société Nationale des Beaux-Arts del 1893 e, per converso, le lodi dello stesso critico all'acquarello ritoccato a tempera intitolato "Venise", realizzato da Moreau nel 1885. Successivamente vengono analizzate altre opere di Aman-Jean e di Moreau dedicate a Venezia e ulteriori pareri critici di Lorrain sui due artisti

Information technology and the challenge for Hong Kong
No full textThe twenty-first century is frequently cited as the Asia- Pacific Century due to the phenomenal success of Asian countries over the last three decades. Nowhere has this been more visible than in Hong Kong which became the first Newly Industrialized Economy to enter the world's top ten trading communities in 1991. This book describes the current state of information technology (IT) exploitation in Hong Kong and the role of IT in the rapid advancement of the Asia-Pacific region. It raises issues - such as the impact of politics, culture and societal growth on IT effectiveness - but does not try to provide all the answers, and is therefore of interest to both business and IT managers in global organizations or companies operating in cross-cultural settings. It is also invaluable for students of business, management and IT who will play a strategic role in the future development of the new global economypublished_or_final_versionPreface pviiContributors pixIndex p381Sect.1 Information technology in Asia: the role of Hong Kong as a regional and global hub p1Sect.2 Practices, Problems and productivity in Hong Kong p119Sect.3 Strategic application and exploitation of IT in Hong Kong p2491 Hong Kong as a hub for regional and international business / Burn, Jancie M. p32 IT policies and information infrastructures: comparing Hong Kong to the Singapore model / Martinsons, Maris G. p273 Hong Kong's communication infrastructure: the evolving role of a regional information hub / Petrazzini, Ben p614 Electronic commerce and EDI in Asia / Burn, Janice M. p915 The use of information technology: practices and problems / Ng Tye, Eugenia M.W. p1216 IT manpower issues in Hong Kong / Chau, Patrick Y.K. p1417 Improving application development productivity: a Hong Kong study / Lee, Sunro p1698 CASE in Hong Kong / Karimi, Jahangir p1939 Business process change enabled by information technology: case studies and cultural constraints / Martinsons, Maris G. p22110 The strategic application of IT in Hong Kong / Burn, Janice M. p25111 Information technology to enable global banking: the HongKongBank and HEXAGON / Martinsons, Maris G. p26712 Strategic use of IT for competitive and cooperative advantage by small-medium local banks in Hong Kong / Elliot, Steve R. p29913 Strategic approach to information technology at the Hong Kong Jockey Club / Loebbecke, Claudia p31914 SMART use of information technology in Hong Kong / Burn, Janice M. p34115 Strategic use of IT in port management / Burn, Janice M. p35
Prediction of soft X-ray photo-electron/absorption spectra by ab initio calculations
No full textWe present two different theoretical approaches used to predict the photoelectron and the photoabsorption and discuss their accuracy by comparison with new experimental data.
The first method has been developed specifically for molecular inner shell excitation and ionization by Nobuhiro Kosugi since 1980 and implemented in the GSCF3 code. [1] Here the core ionized states and core-to-excited states transitions are solved within the Hartree-Fock approximation by explicitly taking into account the core hole. The excited orbitals to be singly occupied by the core-electron excitations are optimized within the STatic EXchange (STEX) method by freezing the core and the occupied valence HF orbitals of the corresponding core hole state. The calculations have been run for several molecules of biological interest (tyramine, tryptamine, tryptophol, barbituric and thiobarbituric acid) and the obtained XPS and NEXAFS spectra have been compared with the experimental results. [2]
The second approach has been developed by Angela Acocella in order to investigate the onset of the ionization dynamics in photoelectron spectroscopy with a quantum-mechanical time-dependent propagator used to evolve the electronic wavefunction [3] with the aim to correlate it to the spectral analysis. In practice, the high energy of the incoming photon triggers a complicated re-organization of the wavefunction where the usually dominant one-photon contribution is combined with all the possible many-photon contributions of the same energy, together with the continuum states of the ionized electron. The presented model proved to reproduce with reasonable accuracy both XPS and UPS spectra of the coronene molecule. [4]

Analysis of Yield Spreads on Commercial Mortgage-Backed Securities
No full textYield spreads on commercial mortgage-backed securities (CMBS) are defined as the difference between the yield on CMBS and the yield on comparable-maturity Treasuries. CMBS yield spreads declined dramatically from 1992 until 1997, then increased in 1998 and 1999. The relationship between CMBS yield spreads and other variables is estimated in an effort to explain recent trends. Results identify several variables that are related to yield spreads on both fixed-rate and variable-rate CMBS. However, even after controlling for other observable factors, the yield spread on CMBS still declined from 1992 until 1997, then increased each of the next two years. Possible explanations for this phenomenon are explored.

No full textHere, we report the draft genome sequence of Dietzia maris, known previously as Rhodococcus maris. It is 3,505,372 bp in size with a G+C content of 73%. The draft genome sequence will improve our understanding of Dietzia maris related to other mycolata species and constitutes a basic tool for exploring the cell wall proteins
Enhancement of biomass and total carotenoid content of a UV-resistant strain of Dietzia maris in response to different carbon and nitrogen sources
No full textIn the present study, the effect of various fermentation media on the production of carotenoid pigment in a ra dia tion-resistant strain of Dietzia maris was reported. The biomass and pigment production of this strain was eva luated using various sources of carbon and nitrogen as well as different concentrations of whey medium. The anti oxidant and cytotoxic activities of the extracted pigment were also determined using ferric reducing anti oxidant power (FRAP), 2,2-diphenyl-1-picrylhydrazyl radicals (DPPH), and MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assays. The antibacterial activity of the carotenoid pigment was also evaluated. All carbon sources increased the pigment production of D. maris in the following order: glucose > raffinose = starch = xylose > sorbitol > sucrose. However, only glucose, xylose, and sorbitol significantly increased the microbial biomass as compared to the control. Moreover, all organic nitrogen sources and ammonium sulfate enhanced the pigment production of the studied strain by approximately 6–9 folds. The free radical scavenging capacity and FRAP of the D. maris carotenoid extract were reported as half-maximal effective concentration or EC50= 3.30 mg/ml and EC50 = 28.46 μg/ml, respectively. The maximum amount of biomass and carotenoid pigment produced by D. maris was obtained in the fermentation medium containing 1 g/l glucose and 1 g/l yeast extract (18 mg/l). This strain can be considered as a promising biocatalyst for the commercial production of natural carotenoids due to its antioxidant capacity and noncytotoxic activity

MARIS: A national project on marine robotics for interventions
No full textThe MARIS project arises as initiative of four Departments of Universities which are members of the Inter-University Centre ISME ('Integrated Systems for the Marine Environment'), legally represented by the University of Genoa, and the research unit of Genoa of CNR-ISSIA ('Institute for Studies on Intelligent Systems for Automation?) of the National Council of Research of Italy, with headquarter in Bari. The two institutions qualify for their long-term research experience in the application of ICT to the marine environment, with particular interests directed toward Underwater Robotics, intended in all its methodological, technological and applicative aspects. The initial research consortium has been then enriched by the inclusion of two additional University Departments, which have selected for the highly qualified contributions they can provide to the MARIS project. In this framework, the proposing institutions ISME and CNR-ISSIA have established, as general strategic objective of the project, the one of studying, developing and integrating, technologies and methodologies enabling the development of underwater robotized systems employable for manipulation and transportation activities; within underwater scenarios which are deemed progressively becoming typical for the off-shore industry, for search-and-rescue operations, as well as for underwater scientific missions. Within such ambitious objective, the proposing institutions also intend to demonstrate the achievable operational capabilities, in a proof-of-concept form, by also integrating the results within prototype experimental systems. In fact, on the basis of the knowledge and experiences owned by the consortium; of its available logistic structures, laboratories and equipment; as well on the basis of already available advanced-stage designs for the experimental systems; the consortium is confident on the possibility of coordinately develop all the necessary technological and methodological aspects; while also converging toward their final integration on the mentioned prototype systems; to be in parallel realized; starting from the sub-systems and advanced-stage
