Numerical simulation of tests for the evaluation of the performance of the reinforced concrete slabs strengthening by FRCM

AbstractIn this work the attention is focused to the numerical simulation of the experimental bending tests carried out on a total of six reinforced concrete r.c. plates the latter aimed to provide a basic understanding of the its performance when strengthened by Fiber Reinforced Cementitius Matrix (FRCM) Composites. Three of those were used as control specimens. The numerical simulation was carried out by LUSAS software. A good correlation between the FE results and data obtained from the test, both in the load–deformation behavior and the failure load was highlighted. This permits to prove that applied strengthening system gives back an enhancement 2.5 times greater in respect of the unreinforced case. A greater energy dissipation ability and a residual load-bearing capacity makes the proposed system very useful in the retrofitting as well as in the case of strengthening of bridge structures. Based on the validation of the FE results in bending, the numerical analysis was also extended to characterize the behavior of this strengthening system in tensile

Out of Plane Behavior of Calcareous Masonry Panels Strengthened by CFRP

AbstractThis paper presents the results obtained by an experimental program carried out to evaluate the influence of externally bonded FRP composites on the out of plane behavior of masonry. To this aim two groups of samples were tested for static out-of-plane loads under different vertical load applying orthogonally to the mortar beds. Three panels Carbon fiber- Reinforced Masonry (CRM) were reinforced by one layer of carbon fiber-reinforcing system attached to the tension side of the wall, while the remaining unreinforced three (URM) were used as referring samples. The failure loads, collapse mode, mid-span deflection and fiber-debonding were measured. Based on the data obtained from the experimental program, it appears that the out-of-plane CFRP reinforcement tends to deeply decrease the out-of plane deflection, change the collapse mechanism, and increase enormously its out of plane resistance up to seven times respect to the URM panel

PACAP and NAP : Effect of Two Functionally Related Peptides in Diabetic Retinopathy

Pituitary adenylate cyclase-activating polypeptide (PACAP) is a peptide involved in physio-pathological processes of the eye. It exerts multiple effects directly through activation of its related receptors and indirectly through increases in the synthesis of activity-dependent neuroprotective protein (ADNP). To study the role of ADNP and protect against ADNP deficiencies, a small peptide called NAP was synthetized. It includes an eight amino acid active site sequence of ADNP. In this review, we summarize the knowledge regarding the neuroprotective function played by PACAP and NAP in retinal tissue and provide an overview of the correlation between PACAP and ADNP in the context of diabetic retinopathy

Trojan Horse Investigation for AGB Stellar Nucleosynthesis

Asymptotic Giant Branch (AGB) stars are among the most important astrophysical sites influencing the nucleosynthesis and the chemical abundances in the Universe. From a pure nuclear point of view, several processes take part during this peculiar stage of stellar evolution thus requiring detailed experimental cross section measurements. Here, we report on the most recent results achieved via the application of the Trojan Horse Method (THM) and Asymptotic Normalization Coefficient (ANC) indirect techniques, discussing the details of the experimental procedure and the deduced reaction rates. In addition, we report also on the on going studies of interest for AGB nucleosynthesis

The 10B(p,α)7Be S(E)-factor from 5 keV to 1.5 MeV using the Trojan Horse Method

The 10 B(p, α ) 7 Be reaction is the main responsible for the 10 B destruction in stellar interior [1]. In such environments this p-capture process occurs at a Gamow energy of 10 keV and takes places mainly through a resonant state (Ex = 8.701 MeV) of the compound 11 C nucleus. Thus a resonance right in the region of the Gamow peak is expected to significantly influence the behavior of the astrophysical S(E)-factor. The 10 B(p, α ) 7 Be reaction was studied via the Trojan Horse Method (THM) applied to the 2 H( 10 B, α 7 Be)n in order to extract the astrophysical S(E)-factor in a wide energy range from 5 keV to 1.5 MeV

BEYOND THE DARK: analisi dei costumi nella filmografia di Tim Burton

L'elaborato "BEYOND THE DARK: analisi dei costumi nella filmografia di Tim Burton" è un analisi riguardo la filmografia di Tim Burton, con particolare attenzione rivolta al costume. Sono stati scelti quattro film per la suddetta analisi: "Beetlejuice" (1988), "Edward mani di forbice"(1990), "La Fabbrica di Cioccolato" (2005) e "Alice in Wonderland" (2010). Nell'Introduzione vengono esplicate le motivazioni che hanno portato a condurre questo studio. Nel capitolo I viene fatto un breve excursus sull'importanza dek costume cinematografico, facendo anche esempi di film iconici. Nel capitolo II viene descritta in maniera parziale il laoro di Tim Burton, dagli esordi fino ai giorni nostri, sia come animatore che come regista. I capitolo III, IV, V, VI affrontano i film scelti, ponendo l'attenzione sui costumi, la loro simbologia, e la loro importanza all'interno delle pellicole, in quanto elementi di costruzione dei personaggi
