A new displacement-based framework for non-local Timoshenko beams
2015
In this paper, a new theoretical framework is presented for modeling non-locality in shear deformable beams. The driving idea is to represent non-local effects as long-range volume forces and moments, exchanged by non-adjacent beam segments as a result of their relative motion described in terms of pure deformation modes of the beam. The use of these generalized measures of relative motion allows constructing an equivalent mechanical model of non-local effects. Specifically, long-range volume forces and moments are associated with three spring-like connections acting in parallel between couples of non-adjacent beam segments, and separately accounting for pure axial, pure bending and pure sh…
Trattamenti a base di TiO2 nanocristallina ad azione protettiva indiretta fotocatalitica applicati ai beni architettonici
2009
The research is focused on the definition of a diagnostic program to verify a protective product for stone surfaces. The objective is, in particular, to verify the treatments efficacy of nanocrystalline TiO2 (Titania) with indirect photocatalytic protective action, in the form of thin films made through the sol-gel method, and applied to the stone materials of the Monumental Heritage, through a poly-methodological scientific research, that allow to assess the innovative behaviour towards the fundamental principles of conservation and restoration of the architectural-artistic heritage. To define the research’s program have collaborated Department of Geosciences of University of Padova, ISTM-…

The Multi-period Multi-trip Container Drayage Problem with Release and Due Dates
2021
Abstract The Container Drayage Problem (CDP) aims at routing a fleet of trucks, based at a common terminal, to serve customers while minimizing the total travel distance. Each trip starts from and ends at the terminal, and handles a subset of customers. Each customer requires either that a container is picked up or delivered. We introduce a more realistic variant, i.e., the Multi-trip Multi-period CDP with Release and Due Dates (MM-CDP-RDD), in which the planning horizon is composed of several periods (days). On each day, each truck may perform more than one trip respecting the Release and Due Dates (RDD) associated with customer services, corresponding to the first and the last day on whic…
Tufted angiomas in childhood: A series of 9 cases and a literature review
2015
Introduction: Tufted angioma (TA) is a rare benign vascular tumour that mostly appears during infancy or early childhood, although there are cases reported in adults. Clinical presentation and evolution of TA can vary. Histologically, it takes on a classic appearance of vascular tufts (“cannon ball” like appearance). Patients and methods: A retrospective observational study was conducted that included all patients diagnosed with TA at our centre in the last 20 years. Results: A series of 9 cases of tufted angioma in childhood are presented, 77.7% of which were congenital. This represents a frequency higher than previously described. Spontaneous regression was observed in 55.5% of the cases,…
Analysis of p53 and mdm2 proteins in malignant fibrous histiocytoma in absence of gene alteration: prognostic significance.
2000
TP53 and MDM2 genes and their protein expression were evaluated in frozen and paraffin-embedded tissue from 27 patients with malignant fibrous histiocytoma to elucidate the relationship between them, their implication in tumor progression mechanisms and their possible diagnostic-prognostic value in malignant fibrous histiocytoma. Single-strand conformation polymorphism analysis and direct sequencing of polymerase chain reaction-amplified DNA were used to establish two TP53 mutations (7.4%): a point mutation and a 63-bp duplication. Amplification of the MDM2 gene was observed in two tumors (7.4%) by means of Southern-blot analysis, one of them also carrying the TP53 point mutation. Immunohis…
