Elementi di interfaccia per l’analisi di strutture murarie
Elio Sacco,Jessica Toti
Frattura ed Integrità Strutturale , 2009,
Abstract: Il presente articolo riguarda la modellazione del comportamento meccanico di elementi in muratura intesi come sistemi eterogenei composti da malta, blocchi ed interfacce di connessione. La strategiacomputazionale che viene adottata consiste nel modellare separatamente i blocchi, i letti di malta ed le interfacce responsabili di fenomeni di decoesione malta-blocco; a tale scopo, si propone uno speciale modello di interfaccia che combina il danneggiamento con l’attrito. Si sviluppa una procedura numerica, basata sull’algoritmo backward di Eulero, per risolvere il problema evolutivo; per il passo temporale si utilizza invece la tecnica predictor-corrector a controllo di spostamenti. Si effettuano alcune applicazioni numeriche con lo scopodi verificare la capacità del modello e dell’algoritmo proposto nel riprodurre la risposta non lineare della muratura dovuta a fenomeni di degrado localizzati. Infine, si conduce lo studio della modellazione di un arco murario, confrontando i risultati numerici con quelli sperimentali; si dimostra la abilità del modello proposto nel simulare il comportamento globale della struttura ad arco in termini di carico ultimo e di meccanismo di collasso.
Bond Behavior of Historical Clay Bricks Strengthened with Steel Reinforced Polymers (SRP)
Ernesto Grande,Maura Imbimbo,Elio Sacco
Materials , 2011, DOI: 10.3390/ma4030585
Abstract: In the strengthening interventions of past and historical masonry constructions, the non-standardized manufacture processes, the ageing and the damage of masonry units, could significantly affect the properties of the surfaces where strengthening materials are applied. This aspect requires particular care in evaluating the performance of externally bonded strengthening layers, especially with reference to the detachment mechanism. The bond response of old masonries could be very different from that occurring in new masonry units which are the ones generally considered in most of the bond tests available in technical literature. The aim of the present paper is the study of the bond behavior of historical clay bricks strengthened with steel reinforced polymers (SRP) materials. In particular, the results of an experimental study concerning new manufactured clay bricks and old bricks extracted from different historical masonry buildings are presented. The obtained results, particularly in terms of bond resistance, detachment mechanism and strain distributions, are discussed for the purpose of analyzing the peculiarities of the historical bricks in comparison with new manufactured ones. Some considerations on the efficacy of the theoretical formulations of the recent Italian code are also carried out.
A Clifford algebraic analysis gives mathematical explanation of quantization of quantum theory and delineates a model of quantum reality in which information, primitive cognition entities and a principle of existence are intrinsically represented ab initio  [PDF]
Elio Conte
World Journal of Neuroscience (WJNS) , 2013, DOI: 10.4236/wjns.2013.33021

The thesis of this paper is that Information, Cognition and a Principle of Existence are intrinsically structured in the quantum model of reality. We reach such evidence by using the Clifford algebra. We analyze quantization in some traditional cases of quantum mechanics and, in particular in quantum harmonic oscillator, orbital angular momentum and hydrogen atom. The results are confirmed analyzing human cognition behavior that evidences a very consistent agreement with the basic quantum mechanical foundations.

Can Current Quantum Cognition Studies Give Indication on the Manner in Which Human Cognition Arose ab Initio?  [PDF]
Elio Conte
Psychology (PSYCH) , 2014, DOI: 10.4236/psych.2014.58090

It is advanced the view that the primary elements of cognition and matter both started ab initio as represented in quantum mechanics.

Additional Comments Added to Our Recent Answer to G. Ghirardi  [PDF]

Journal of Modern Physics (JMP) , 2015, DOI: 10.4236/jmp.2015.61002
Abstract: Recently we published on International Journal of Theoretical Physics an answer to G. Ghirardi relating a paper published by this author in 1999. Since the argument is so complex and articulated, in the present paper we add further comments relating in particular the matter of the quantum collapse as we have elaborated it in our previous work using only Clifford algebra and thus reaching the basic result that it is a mechanism involving only information with a cybernetic collapse and retrocollapse dynamics as first it was introduced by Costa de Beauregard. We evidence as quantum collapse involves directly our psyche and our consciousness that of course is by itself an entity selecting alternatives on the basis of quantum rules. According to our previous experiments we also add comments on the possibility to estimate quantum interference at the level of perception and cognitive dynamics and reconstruct the wave function giving the possibility such result to discriminate between pure quantum superposition of states and mixtures just to re-confirm the role of quantum mechanics at the basic structure of mental entities.
What Path Monitor: A Brief Note on Quantum Cognition and Quantum Interference, the Role of the Knowledge Factor  [PDF]
Elio Conte
Psychology (PSYCH) , 2015, DOI: 10.4236/psych.2015.63029
Abstract: We discuss a celebrated experiment of quantum mechanics to evidence that quantum mechanics delineates a novel feature of our reality in which cognition enters as primary element, strongly linked ab initio to the dynamics of matter.
Fibonacci Harmonics: A New Mathematical Model of Synchronicity  [PDF]
Robert G. Sacco
Applied Mathematics (AM) , 2018, DOI: 10.4236/am.2018.96048
This article aims to provide a brief overview of the relevance of new findings about the Fibonacci Life Chart Method (FLCM) for understanding synchronicity. The FLCM is reviewed first, including an exposition of the golden section model, and elaboration of a new harmonic model. The two models are then compared to illuminate several strengths and weaknesses in connection with the following four major criteria regarding synchronicity: explanatory adequacy; predictability of future synchronicities; simplicity of the model; and generalizability to other branches of knowledge. The review indicates that both models appear capable of simulating nonlinear and fractal dynamics. Hybrid approaches that combine both models are feasible and necessary for projects that aim to experimentally address synchronicity.
Characterization of the Geographical and Varietal Origin of Wheat and Bread by Means of Nuclear Magnetic Resonance (NMR), Isotope Ratio Mass Spectrometry (IRMS) Methods and Chemometrics: A Review  [PDF]
Francesco Longobardi, Daniela Sacco, Grazia Casiello, Andrea Ventrella, Antonio Sacco
Agricultural Sciences (AS) , 2015, DOI: 10.4236/as.2015.61010
Abstract: In recent years, food authentication, in terms of geographical and varietal/animal origins, is considered of primary importance at all levels of the production process. Therefore, it is clear that there is an economic basis to develop analytical methods able to certify the declared origin of food products, in order to protect consumers and honest producers from fraud and unfair competition, respectively; consequently, during recent years, several food authentication techniques have been proposed. This review attempted to present in a critical way the contribution of High Resolution Nuclear Magnetic Resonance (HR-NMR) and Isotope Ratio Mass Spectrometry (IRMS) techniques in the assessment of quality and authenticity, mainly in terms of characterization of geographical and varietal origin, of wheat and wheat products, focusing on the most important studies to this direction.
Update on entecavir in the management of severe forms of Hepatitis B

Hepatic Medicine: Evidence and Research , 2012, DOI: http://dx.doi.org/10.2147/HMER.S16136
Abstract: ate on entecavir in the management of severe forms of Hepatitis B Review (1909) Total Article Views Authors: Sacco R Published Date May 2012 Volume 2012:4 Pages 39 - 47 DOI: http://dx.doi.org/10.2147/HMER.S16136 Received: 25 November 2011 Accepted: 11 March 2012 Published: 15 May 2012 Rodolfo Sacco Department of Gastroenterology, Pisa University Hospital, Pisa, Italy Abstract: Despite the effective management of most cases of hepatitis B virus (HBV) infection, there is still much room for improvement in the treatment of more severe cases of hepatitis B, such as those occurring in patients with decompensated cirrhosis, in transplanted subjects, and in patients with exacerbations of HBV infection. Among the treatments currently approved for the therapy of hepatitis B, entecavir determines a rapid suppression of viral load. This drug is also associated with a high genetic barrier and an overall favorable safety profile. This review provides an overview of recent evidence related to the use of entecavir in the management of the most severe forms of hepatitis B. The results obtained for this drug in real-life clinical practice are also reviewed.
Political participation of immigrants through new urban policies in Brussels : constraints and small opportunities Participation politique des immigrés à travers les nouvelles politiques urbaines à Bruxelles : contraintes et manque d’opportunités
Muriel Sacco
Belgeo : Revue Belge de Géographie , 2012,
Abstract: The political participation of immigrants is an important gauge of their integration into the receiving society more generally, as well as an indicator of the degree of openness of political elites towards ethnic minorities. With the restructuring of State intervention and the diffusion of civic culture, the role that immigrant associations play in shaping urban social policies has become another important form of political participation. As the Belgian city with the highest percentage of migrants and naturalized foreigners and benchmarked as multicultural by the regional government, Brussels presents a test case. Since the beginning of the nineties, new public policies including participative tools have been introduced in Brussels. However, immigrant associations are not adequately involved in these processes. Why is such little space given to migrant associations in the participative procedures of these new urban policies? The neo-institutionalist perspective will be helpful in identifying the major factors that explain the relatively low participation of immigrant associations. La participation politique des immigrés est un indicateur important à la fois de leur intégration dans la société d’accueil et du degré d’ouverture des élites politiques à l’égard des minorités ethniques. Avec les mutations de l’intervention de l’Etat et la diffusion d’une culture civique, les espaces participatifs des politiques socio-urbaines offrent une forme de participation politique nouvelle pour les associations d’immigrés. Bruxelles est un cas intéressant. D’une part, la capitale est la ville belge qui accueille le plus haut pourcentage de personnes étrangères et d’origine étrangère et est présentée comme ville multiculturelle par le gouvernement régional. D’autre part, depuis les années 1990, des nouvelles politiques publiques incluant des outils participatifs ont été implémentées à Bruxelles. Cependant, les associations d’immigrés ne sont pas adéquatement intégrées dans ces espaces. Pourquoi réserve-t-on si peu d’espace à ces associations ? La perspective néo-institutionnaliste est utile pour identifier les facteurs expliquant cette faible participation des associations d’immigrés.
