Planned preventive maintenance in the preservation of historic heritage sites as a first form of valorisation
Paolo Gasparoli
Techne : Journal of Technology for Architecture and Environment , 2012,
Abstract: This research develops various reflections on the role and repercussions of planned preventive maintenance activities in historic heritage sites as an opportunity for their valorisation. The first step is to define the terminology, underscoring reciprocal relationships and the need to organise structured activities and applications that outline contents, procedures and processes for interventions, with innovative strategies that promote the preservation and valorisation of cultural heritage sites. In this sense, this paper proposes the experimental results of work projects conducted on significant cases.
The formation of new compounds
Gasparoli, A.
Grasas y Aceites , 1998,
Abstract: The formation of new compounds The study of model systems allows us to reconstruct the complex mosaic of reactions which make up the frying process. In particular such systems, if made up of single oils or their components, verify the transformation of the triglyceride matrix by thermo-oxidizing treatment. Should this then have added specific substrates (protein, starch) they reconstruct the oil-substrate interaction and the influence of the same substrate in the transformation. The contribution of the information is equally distributed between the volatile products and the complex products; in fact both contribute to indicate the reactions in play, supporting the previous considerations for investigation at an analytical level. The present work discusses the newly formed products (volatile or nonvolatile), verifying in particular the formation of reaction products with the substrates.
A Field Experiment on the Recurrence of Large Waves in Wind Seas  [PDF]
Paolo Boccotti
Open Journal of Marine Science (OJMS) , 2011, DOI: 10.4236/ojms.2011.13007
Abstract: Wind generated sea waves are generally regarded as an example of pure randomness in nature. Here we give a proof that the matter is not exactly so: some identical sequences of relatively large waves were found many hours apart from one another. This finding supports the theory of quasi determinism of sea waves.
Call Auction Markets with Risk-Averse Specialists  [PDF]
Paolo Vitale
Theoretical Economics Letters (TEL) , 2012, DOI: 10.4236/tel.2012.22030
Abstract: We study a generalization of Kyle’s (1985) model to the case in which the specialist is risk-averse and does not set the transaction price according to semi-strong form efficiency. We see that Kyle’s call auction market is no longer a robust market structure, as linear Bayesian equilibria do not exist, irrespective of fundamentals, such as agents’ information, endowments and preferences. This result holds both when customers can submit only market orders and when limit orders are allowed too.
Democratic, Plutocratic and Social Weights in Price Indexes  [PDF]
Paolo Liberati
Theoretical Economics Letters (TEL) , 2012, DOI: 10.4236/tel.2012.25084
Abstract: This paper introduces social considerations into the calculation of the price index. To this purpose, recourse is made to the concept of distributional characteristic. It is shown how an aggregate price index can be expressed as a weighted average of commodity-specific prices, with weights that depend on both the aggregate share of consumption and the way in which consumption is distributed across households. The proposed index provides a complementary basis for the analysis of the impact of inflation and for the calculation of its social value.
Holographic Bound in Quantum Field Energy Density and Cosmological Constant  [PDF]
Paolo Castorina
Journal of Modern Physics (JMP) , 2013, DOI: 10.4236/jmp.2013.46110
Abstract:

The cosmological constant problem is reanalyzed by imposing the limitation of the number of degrees of freedom (d.o.f.) due to entropy bounds directly in the calculation of the energy density of a field theory. It is shown that if a quantum field theory has to be consistent with gravity and holography, i.e. with an upper limit of storing information in a given area, the ultraviolet momentum cut-off is not the Planck mass, Mp, as naively expected, but \"\" where Nu is the number of d.o.f. of the universe. The energy density evaluation turns out completely consistent with Bousso’s bound on the cosmological constant value. The scale \"\" , that in the “fat graviton” theory corresponds to the graviton size, originates by a self-similar rearrangement of the elementary d.o.f. at different scales that can be seen as an infrared-ultraviolet connection.

Outline of a Proposal to Reform the Institutional Architecture of Money, Savings, and Credit to Reach a Financial Sustainability  [PDF]
Paolo Savona
Modern Economy (ME) , 2018, DOI: 10.4236/me.2018.96071
Abstract:

The scope of this paper is to examine the complications raised by technical innovations in the financial field (fintech). The conclusion of this enquire is that the current institutional architecture cannot guarantee monetary and financial sustainability as long as Governments decide to reform it using the already available instruments (cryptocurrency, blockchain, algorithms) instead of leaving them free to operate or limiting their use as they are doing. The same goes for any tentative to restate bank credibility forecasting money and financial instability starting from big data treated with traditional econometric methods.

Time dependent dispersion of nanoparticles in blood vessels  [PDF]
Francesco Gentile, Paolo Decuzzi
Journal of Biomedical Science and Engineering (JBiSE) , 2010, DOI: 10.4236/jbise.2010.35072
Abstract: The dispersion of intravasculary injected nanoparticles can be efficiently described by introducing an effective diffusion coefficient Deff which quantifies the longitudinal mass transport in blood vessels. Here, the original work of Gill and Sankarasubramanian was modified and extended to include 1) the variati- on over time of Deff; 2) the permeability of the blood vessels and 3) non-Newtonian rheology of blood. A general solution was provided for Deff depending on space (?), time (?), plug radius (?c) and a subset of permeability parameters. It was shown that increasing the vessel plug radius (thus hematocrit) or permeability leads to a reduction in Deff, limiting the transport of nanoparticles across those vessels. It was also shown that the asymptotic time beyond which the solution attains the steady state behaviour is always independent of the plug radius and wall permeability. The analysis presented can more accurately predict the transport of nanoparticles in blood vessels, compared to previously developed models.
Syndication and Secondary Loan Sales  [PDF]
Paolo Colla, Filippo Ippolito
Theoretical Economics Letters (TEL) , 2011, DOI: 10.4236/tel.2011.13017
Abstract: Secondary loan sales give originating banks the opportunity to diversify part of their credit risk by selling loans to other market participants. However, as originating banks are less exposed to risk after secondary loan sales, their incentives to monitor borrowers diminish. Secondary loan sales therefore involve a trade-off between diversification benefits and sub-optimal monitoring. We explore this trade-off within a theoretical model. The results show that in equilibrium loans trade at a discount because monitoring effort is sub-optimally low. We illustrate how this inefficiency is related to lack of transparency in the secondary loan market, and provide policy implications to address this problem.

Paolo Di Sia
Theoretical Economics Letters (TEL) , 2012, DOI: 10.4236/tel.2012.22032
