Propeller Flaps: A Review of Indications, Technique, and Results

2014

In the last years, propeller flaps have become an appealing option for coverage of a large range of defects. Besides having a more reliable vascular pedicle than traditional flap, propeller flaps allow for great freedom in design and for wide mobilization that extend the possibility of reconstructing difficult wounds with local tissues and minimal donor-site morbidity. They also allow one-stage reconstruction of defects that usually require multiple procedures. Harvesting of a propeller flap requires accurate patient selection, preoperative planning, and dissection technique. Complication rate can be kept low, provided that potential problems are prevented, promptly recognized, and adequate…

Intralipotherapy, the State of the Art.

2016

Background: Reconstruction intralipotherapy is a term commonly used in the field of aesthetic medicine, above all in Europe, which defines a specific injection technique developed for the treatment of localized fat with substances that provoke the lysis of adipocytes by means of an injection directly into the adipose tissue with a long needle. The aim of this study is to define the technique in detail and everything that is associated with it, on the basis of years of multicenter experience by doctors who perform it. Materials and Methods: From January 2010 to December 2014, 3,080 European physicians were trained in intralipotherapy technique, and approximately 152,500 patients were treated…

Unravelling the GLY-PRO-GLU tripeptide induced reconstruction of the Au(110) surface at the molecular scale

2018

International audience; The adsorption of GLY-PRO-GLU tripeptide on Au(110) is investigated within the frame of all atom classical mechanics simulations and Density Functional Theory, focusing on the surface reconstruction. It is shown that the tripeptide adsorption reorganizes and restructures the Au(110) surface. A mechanism for the surface restructuration is proposed for both the neutral and zwitterionic form of the peptide at room temperature in Ultra High Vacuum. Diverse residues may be involved in the Au atoms displacement, and in particular glutamic acid, triggering a double proton transfer and the formation of a zwitter ionic state, is found to be responsible for the triggering of t…

Outcomes of a Teaching Learning Sequence on Modelling Surface Phenomena in Liquids

2023

In this paper we discuss the effects of modelling and computer simulation activities in promoting student use of lines of reasoning useful to explain proposed or observed situations. The activities are part of a structured Teaching/Learning Sequence on surface phenomena in liquids. We outline a model of liquid based on a mesoscopic approach, examples of computer simulations students can use during the activities, and we describe the Teaching/Learning Sequence. During the pedagogical activities, students can simulate the liquid behaviour by controlling many simulation parameters, such as the interaction intensity among liquid and solid particles. The results of the analysis of student answer…

“How Real People Really Need Mathematics in the Real World”—Authenticity in Mathematics Education

2018

This paper discusses authenticity from the perspective of mathematics education. Often, school mathematics offers students inauthentic word problems, which don’t show the authentic usefulness of mathematics in real life. In some tasks, authentic aspects are combined with inauthentic ones (e.g., an authentic context, but the question is artificial and different from what people within that context would ask). Several studies show that students are more motivated by authentic questions than by authentic contexts. Embedding these findings, I discuss issues associated with defining authenticity in education. A first issue is that philosophers use the term to characterize a person’s existential …

Tipologia, materiali e costruzione: i prospetti colonnati pubblici in Sicilia dall’età post-unitaria al ventennio fascista, tra reminiscenze archeolo…

2020

The paper analyses the debate in Sicily on the construction of the monumental colonnaded porticoes that characterise the facades of public edifices built on the island from the post- Unification period to the Fascist regime. The pronao of the Massimo Theatre in Palermo (from 1875) marks the climax of a cultural movement, which, for almost a century, was to associate the neo-Greek style with public buildings and the material of choice of Sicily’s church building tradition in a deterministic manner. Calcarenite was used to build the peristyles of the temples of the archaic and classical age, with imposing, tapered and grooved columns consisting of overlapping sections. In the Fascist period, …

Changing driver behavior during floods: Testing a novel e-health intervention using implementation imagery

2021

Abstract We tested the efficacy of a novel implementation imagery intervention (N = 460) in promoting safer intentions regarding driving into floodwater post-intervention, and at a four-week follow-up using a pre-registered randomized controlled design. Results showed that the intervention reduced intentions and subjective norms regarding driving into floodwater. The control condition also improved on intentions and subjective norms, but the changes appeared to only be maintained at the follow-up for the intervention group and the between group difference at the follow-up was not significant based on our pre-specified cutoff level for statistical significance of 0.01. Results also indicated…

Single-staged laryngotracheal reconstruction for idiopathic tracheal stenosis.

2013

Background This study retrospectively evaluated the results of surgically treated idiopathic tracheal stenosis. Methods Of the 220 patients surgically treated for idiopathic subglottic and tracheal stenosis in the participating hospitals, we reviewed the surgical records of all patients with idiopathic tracheal stenosis. This subgroup required resection of all of the involved mucosa but frequently had undergone more conservative treatments that damaged the tracheal mucosa and cartilage and complicated the definitive surgical treatment. Results During the study period, 60 women (93.8%) and 4 men (6.2%), who were a mean age of 50 years (range, 19 to 77 years), were surgically treated for idio…

Method for size optimisation of large wind–hydrogen systems with high penetration on power grids

2013

Wind power generation is growing rapidly in many locations around the world. Power systems are able to absorb large amounts of wind capacity, but operational problems arise when the wind power penetration becomes high. Such factors as voltage dips, frequency variations, low power system stability, low reactive power and power flow imbalances reduce the economic value and represent a barrier to the unlimited development of wind energy. Hydrogen production from wind power that is not matched with hourly electricity demand appears to be an attractive storage option capable of providing a balancing service to the electricity generators and suppliers for mitigation of the negative impacts due to…
