Rischi da sisma e uso di tecnologie appropriate per proteggere il patrimonio esistente : Earthquake risks and use of appropriate technologies to prot…
2017
Nel corso degli ultimi anni molti sono stati in Italia i dibattiti scientifici concentrati su una provata relazione tra sisma ed abusi edilizi. Le calamità naturali vengono favorite e/o accentuate dall’uso speculativo e distruttivo dell’ambiente e sono ancora più disastrose per quelle costruzioni che non hanno i dovuti requisiti di sicurezza. Alla luce di queste considerazioni il contributo illustrare parte dei risultati della ricerca dal titolo: “Interazione tra rischio sismico e costruito abusivo. Caratteri morfologici e tipologici nelle aree a rischio sismico”, condotta dall’Università di Palermo in collaborazione con l’Istituto dell’Egeo, il Comune di Kos e l’università di Salonicco, al…
Marine food web perspective to fisheries‐induced evolution
2021
Abstract Fisheries exploitation can cause genetic changes in heritable traits of targeted stocks. The direction of selective pressure forced by harvest acts typically in reverse to natural selection and selects for explicit life histories, usually for younger and smaller spawners with deprived spawning potential. While the consequences that such selection might have on the population dynamics of a single species are well emphasized, we are just beginning to perceive the variety and severity of its propagating effects within the entire marine food webs and ecosystems. Here, we highlight the potential pathways in which fisheries‐induced evolution, driven by size‐selective fishing, might reson…
Regional Policy Lessons from Finland
2005
The Finnish economy and society has long been dominated by primary production. Post-war economic development was rapid and welfare gaps between the much more developed economies and Finland narrowed and were even partly reversed. Rapid economic expansion together with structural change has had the effect of centralizing both economic activity and population. The trend has been towards the southern and central regions where the metropolitan area of Helsinki and most of the other larger towns and urban centres are located. Together with vigorous technological progress in agriculture and forestry the rapid urbanization and industrialization of the 1960s and 1970s the fastest in Europe altered …
Combined strength and endurance exercise induced fatigue and recovery
2012
Muscular fatigue is usually defined as the inability to maintain a given exercise intensity or adequate muscle force and therefore maximal isometric force, neural activation and fast force production capacity have often used determinants of acute fatigue. The purpose of the present study was to measure the acute effects of combined strength and endurance exercise on force production, muscle activation and work economy. In addition this study investigated the rate of recovery comparing the active and passive recovery models and the association of the initial fitness levels of subjects. 16 (27 ± 4 years old) male reservists performed combined strength (5x10x70%RM leg-press) and endurance (5x1…
Intermittent hypobaric hypoxia applicability in myocardial infarction prevention and recovery.
2012
Abstract Intermittent hypobaric hypoxia (IHH) has been the focus of important research in cardioprotection, and it has been associated with several mechanisms. Intermittent hypobaric hypoxia inhibits prolyl hydroxylases (PHD) activity, increasing the stabilization of hypoxia-inducible factor-1 (HIF-1) and activating crucial adaptative genes. It has been hence suggested that IHH might be a simple intervention, which may offer a thoughtful benefits to patients with acute myocardial infarction and no complications. Nevertheless, several doubts exist as to whether IHH is a really safe technique, with little to no complications in post-myocardial infarction patients. Intermittent hypobaric hypox…
Coupled Electric and Hydraulic Control of a PRS Turbine in a Real Transport Water Network
2019
Although many devices have recently been proposed for pressure regulation and energy harvesting in water distribution and transport networks, very few applications are still documented in the scientific literature. A new in-line Banki turbine with positive outflow pressure and a mobile regulating flap, named Power Recovery System (PRS), was installed and tested in a real water transport network for the regulation of pressure and flow rate. The PRS turbine was directly connected to a 55 kW asynchronous generator with variable rotational velocity, and coupled to an inverter. The start-up tests showed how automatic adjustment of the flap position and the runner velocity variation are able to c…
Neutralization of acid and base solutions by Reverse Electrodialysis with Bipolar Membranes: a sustainable way to recover energy
2020
The large amount of acidic wastewaters produced in various industrial processes can have a large economic and environmental impact. Companies producing waste acid solutions have to send them to specific sites for the neutralization with alkaline solutions. However, efforts have been devoted so far to promote the acid recovery or its reuse. In the perspective of a more circular manufacturing approach, the present work proposes for the first time the use of the novel Bipolar Membrane Reverse Electrodialysis technology as a viable on-site way to convert the chemical energy associated to the pH gradient of waste acid/base solutions into electrical energy. Bipolar Membrane Reverse Electrodialysi…
The Large Hadron–Electron Collider at the HL-LHC
2021
The Large Hadron-Electron Collider (LHeC) is designed to move the field of deep inelastic scattering (DIS) to the energy and intensity frontier of particle physics. Exploiting energy-recovery technology, it collides a novel, intense electron beam with a proton or ion beam from the High-Luminosity Large Hadron Collider (HL-LHC). The accelerator and interaction region are designed for concurrent electron-proton and proton-proton operations. This report represents an update to the LHeC's conceptual design report (CDR), published in 2012. It comprises new results on the parton structure of the proton and heavier nuclei, QCD dynamics, and electroweak and top-quark physics. It is shown how the LH…
Urbs et Civitas: strategies and technologies for the exploitation of “Metropolis South of the third millennium” (CESCAM 2010)
2011
The contribution illustrates a part of the research: "Strategies and Technologies for the valorization of heritage". Objective of the research is to realize new strategies of building recovery and to promote the cultural patrimony local. Le “metropoli del sud del mondo” sono fortemente caratterizzate da significative densità abitative, anche a causa di un incontrollato consumo di suolo e dell’uso improprio del costruito esistente. In Italia, ed in particolare nel centro-sud di questo paese, città come Roma e Napoli e non ultima Palermo presentano forti criticità in termini di degrado edilizio ed ambientale. Il progetto di ricerca sulle “Strategie e tecnologie per la rigenerazione urbana” (t…
