Feasibility study of a combi-PV panel for greenhouse energy supply and water recovery by nightly radiation towards the sky
2011
In southern European areas, characterized by high irradiation, the use of water for both evaporative cooling systems and hydroponic fertigation, represents a serious drawback for crop cultivation under cover. Water recovery systems seem to be an attractive solution, especially when they are integrated in the greenhouse construction. In this research, a feasibility study of applying a water recovery system driven by a combi-PV panel, in a semi-closed greenhouse was carried out. The prototype combi-PV panel was made by coupling an amorphous silicon panel with a sump stacked on the rear PV panel surface and filled with saline water. The system is driven by a cold-heat sink which is the PV pane…
Ventilative cooling application in Mediterranean buildings: impacts on grid interaction and load match
2016
The concept of load matching refers to the simultaneous occurrence of loads and generation in buildings: it can be increased and optimised with modifications on both the energy demand and generation, but its pre-requisite is to guarantee passive energy efficiency. In the Mediterranean areas, a major challenge in new buildings is the increasing overheating even during mildly hot seasons. Ventilative cooling can be a potential solution to such issues and have an impact on load match in buildings and their grid interaction. The study analyses the potential of ventilative cooling to improve the load match in three different case studies in Italy. Ventilative cooling proved viable in moderately …
Does Oxygen Concentration Used for Resuscitation Influence Outcome of Asphyxiated Newly Born Infants Treated With Hypothermia?
2006
To the Editor. — In a recent article, Rutherford et al1 describe the neuroprotective effect of whole-body cooling and selective head cooling in newly born infants suffering from hypoxic-ischemic encephalopathy. MRI studies of infants receiving either of these therapies showed a lesser degree of basal ganglia and thalamic lesions than nontreated controls, which correlates with a better neurologic prognosis. However, no description of the resuscitation maneuvers used is present in the article's “Patients and Methods” section. Thus, the authors do not include details on how many infants were given positive pressure ventilation and, especially, what concentration of oxygen was used, if oxygen s…
Influence of Drilling Technique on the Radiographic, Thermographic, and Geomorphometric Effects of Dental Implant Drills and Osteotomy Site Preparati…
2020
The aim of this comparative study is to analyze the influence of drilling technique on the radiographic, thermographic, and geomorphometric effects of dental implant drills and osteotomy site preparations. One hundred and twenty osteotomy site preparations were performed on sixty epoxy resin samples using three unused dental implant drill systems and four drilling techniques performed with a random distribution into the following study groups: Group A: drilling technique performed at 800 rpm with irrigation (n = 30)

The Sirocco's chamber of Micciulla manor in Palermo : a bioclimatic archetype symbol of legality and civil redemption
2019
La Camera dello scirocco di fondo Micciulla è uno degli oltre trenta esemplari di un antesignano sistema di raffrescamento passivo ipogeo, diffusosi a Palermo tra il XVII e il XVIII secolo. Grotte artificiali scavate al di sotto o in prossimità delle dimore palermitane presso le quali i ricchi signori si rifugiavano per sfuggire alle elevate temperature estive, rese spesso insopportabili dal caldo vento africano di Scirocco. Tra tutte, la Camera dello Scirocco di fondo Micciulla è forse la più nota non solo per la sua particolare e unica struttura “a cielo aperto”, ma anche e soprattutto per i trascorsi storici ad essa legati. Il presente contributo intende ripercorrere le fasi più signific…

The sirocco chambers: passive cooling structures in the XVI century Palermo area
2014
In the past centuries, the plain surrounding the city of Palermo saw the construction of tens of suburban manor houses, called villas, which were referred to as “places of delight” for the amenities they offered during the good season. These architectural machines were built by aristocrats to make living in the countryside more pleasant and to exhibit their families’ richness and power. Among the delights, the Sirocco rooms were very common in Palermo from the Renaissance, and especially beyond to the XVIII century. They were artificial subterranean structures, built close to a water spring in order to reproduce the pleasant conditions of freshness that could be experienced in a natural cav…
