Preliminary Results of ERAS Protocol in a Single Surgeon Prospective Case Series
2022
Background and Objectives: The aim was to compare the intra and postoperative outcomes between the Enhanced Recovery After Surgery (ERAS) protocol versus the standard of care protocol (SCP) in patients who underwent radical cystectomy performed by a single surgeon. Materials and Methods: A retrospective comparative study was conducted including patients who underwent radical cystectomy from 2017 to 2020. Length of stay (LOS), incidence of ileus, early postoperative complications, and number of re-hospitalizations within 30 days were considered as primary comparative outcomes of the study. Results: Data were collected for 91 patients who underwent cystectomy, and 70 and 21 patients followed …
Resource recovery from food waste via biological processes
2021
Abstract The need for sustainable development is driving a major focus shift in the biowaste treatment sector. While traditional practices such as landfilling are progressively being banned/penalized due to their obvious environmental impacts and prevention policies are being implemented, the potential of food waste (FW) as a resource is being increasingly recognized. The immense amounts of FW produced worldwide—and its overall characteristics—make it a promising candidate for resource recovery if collected separately, a practice that is gaining popularity. This chapter aims at giving a general overview of the different processes that are being developed/implemented for resource recovery fr…
Subsistence/Semi-subsistence Agricultural Exploitations: Their Roles and Dynamics within Rural Economy/Rural Sustainable Development in Romania
2014
Abstract Within the Romanian agriculture subsistence / semi-subsistence agricultural exploitations continue to occupy an important part, the characteristics of their organization and functioning imparting a particular kind of dynamics. The study here aims at highlighting the perspectives on the evolution of subsistence / semi-subsistence agriculture in relation to rural economy and the sustainable rural development. Our main purpose is to bring into analysis the core issues which the Romanian small farms have to face and, at the same time, identify / propose solutions which would contribute to the economic recovery of the agricultural exploitations in question.
Sustainable and cost-efficient energy supply and utilisation through innovative concepts and technologies at regional, urban and single-user scales
2019
Abstract The environmental impact of the energy sector and the security and economics of energy supply and utilisation have been raising increasing concerns, stimulating the search for innovative solutions for a sustainable use of resources. This article provides an overview of published research in this area, with a focus on papers contributed in special issues of leading journals dedicated to the series of Conferences on Sustainable Development of Energy, Water and Environment Systems (SDEWES), including the articles in the current special issue. Based on this review, research trends are identified and achievements supporting the energy transition are highlighted. The studies that focused…
Infarctus cérébral et plasticité : focus sur le BDNF
2011
Functional recovery after ischemic stroke largely involves brain plasticity and more accurately its ability to reorganize the neuronal networks spared by the infarct. Studies conducted on animals using different ischemic stroke models have demonstrated that plastic changes are induced by BDNF (Brain-Derived Neurotrophic Factor). Hence, increasing levels of BDNF in the brain is considered a promising therapeutic strategy to reduce post-stroke impairments. In this context, our work had 2 aims: 1) In a rat model, to identify cells involved in the over-production of BDNF and to evaluate the pertinence of the measurement of circulating BDNF levels to estimate brain BDNF levels; 2) In ischemic st…
THE MACHINE OF THE WATER IN PALERMO INTRA-MOENIA - TECHNOLOGIES FOR THE RECOVERY OF TE CITY SCENE
2009
Lo studio tratta il recupero di un vuoto urbano nel centro storico di Palermo. L’ipotesi illustrata riguarda la progettazione di una “macchina dell’acqua” (un canale sulle tracce dell’antico fiume Kemonia) pensata per rappresentare e realizzare le istanze di una nuova società che intende costruire nuovi ambienti sottraendoli al degrado ed alla speculazione. Uno spazio per accogliere eventi effimeri, ma anche per comunicare la storia e la cultura della città. The study characterizes “the element water”, like architectonic material and principle base of the city planning, for the recovery of Palermo intra-moenia and for the valorization of the cultural resources and acclimatizes them local. T…
Metals Recovery from Waste Pickling Solutions by Reactive Precipitation
2021
Pickling is one of the most important steps in steel manufacturing industry. During the process, an acid reacts with the surface oxides causing metal ions accumulation in the pickling solution. Disposal of the waste acid represents a critical issue for the hot-dip galvanizing industry in terms of environmental damage and high costs. Recovering of the main products by using an integrated process, with the perspective of a circular approach, could minimize the wastewater production, leading to reinvigorate this industrial sector economy. In this context, recovery of the metal ions mainly present in the pickling solution, such as Fe and Zn, becomes a critical issue. In this work, the reactive …
Enabling quantum non-Markovian dynamics by injection of classical colored noise
2017
The non-Markovian nature of quantum systems recently turned to be a key subject for investigations on open quantum system dynamics. Many studies, from its theoretical grounding to its usefulness as a resource for quantum information processing and experimental demonstrations, have been reported in the literature. Typically, in these studies, a structured reservoir is required to make non-Markovian dynamics emerge. Here, we investigate the dynamics of a qubit interacting with a bosonic bath and under the injection of a classical stochastic colored noise. A canonical Lindblad-like master equation for the system is derived by using the stochastic wave function formalism. Then, the non-Markovia…
Favignana bio-calcarenite: technological culture, knowledge and recovery
2022
Favignana Island, the biggest one among Egadi islands, is well known for its deposits of calcarenite, which has been extracted and used since ancient times. The landscape of the Island is shaped by the widespread presence of quarries that mark the seaside as well. Furthermore, the constant presence of dry-stone walls, made of calcarenite, and of the characteristic architecture of buildings, represents a hallmark for the rest of Egadi islands as well, making it clear how important the presence of this material has been for the architectural and technological culture of these places.Calcarenite itself, exported by this island, is still a constituent material of many buildings in the western p…
Efficiency advantages of the separated electric compound propulsion system for CNG hybrid vehicles
2021
As is widely known, internal combustion engines are not able to complete the expansion process of the gas inside the cylinder, causing theoretical energy losses in the order of 20%. Several systems and methods have been proposed and implemented to recover the unexpanded gas energy, such as turbocharging, which partially exploits this energy to compress the fresh intake charge, or turbo-mechanical and turbo-electrical compounding, where the amount of unexpanded gas energy not used by the compressor is dedicated to propulsion or is transformed into electric energy. In all of these cases, however, maximum efficiency improvements between 4% and 9% have been achieved. In this work, the authors d…
