Edilizia Storica: Nuove esigenze e Prestazioni

The subject of regeneration of energy resources in historic buildings, in light of the new laws, proposes the abandoning of traditional approaches to a building’s performance in favour of an assessment of its quality with regard to energy and the environment, with a change in concepts and strategies inherent to sustainable construction. In support of the validity of this proposal, the project input will be geared towards achieving aims of environmental sustainability; they will be addressed to historical buildings and contexts, highlighting how interventions traditionally linked to recovery and restoration already implicitly contain many factors that can be shared with the criteria for sustainability. These, having been opportunely checked and calibrated, might then be proposed as a new approach to projects and evaluation

Global constraints on absolute neutrino masses and their ordering

Within the standard three-neutrino framework, the absolute neutrino masses and their ordering (either normal, NO, or inverted, IO) are currently unknown. However, the combination of current data coming from oscillation experiments, neutrinoless double beta decay searches, and cosmological surveys, can provide interesting constraints for such unknowns in the sub-eV mass range, down to O(0.1) eV in some cases. We discuss current limits on absolute neutrino mass observables by performing a global data analysis, that includes the latest results from oscillation experiments, neutrinoless double beta decay bounds from the KamLAND-Zen experiment, and constraints from representative combinations of Planck measurements and other cosmological data sets. In general, NO appears to be somewhat favored with respect to IO at the level of ~2 sigma, mainly by neutrino oscillation data (especially atmospheric), corroborated by cosmological data in some cases. Detailed constraints are obtained via the chi^2 method, by expanding the parameter space either around separate minima in NO and IO, or around the absolute minimum in any ordering. Implications for upcoming oscillation and non-oscillation neutrino experiments, including beta-decay searches, are also discussed.Comment: 17 pages, including 3 tables and 11 figure

Effect of dietary Lippia citriodora extract onproductive performance and meat qualityparameters in hares ( Lepus europaeus Pall. )

Abstract. Three different dietary doses of Lippia citriodora natural extract were tested in order to verify their effect on productive performance and the meat quality of intensively-reared hare (Lepus europaeus Pall.). The 240 day-trial was conducted on 20 male hares, divided into 4 homogeneous groups of 5 animals each. A control group received a basal diet without any supplementation, and the other three experimental groups received a natural extract of Lippia citriodora, titrated in verbascoside, in the following amounts: 1 g, 1.5 g and 2 g of natural extract/kg feed in the low (LNE), medium (MNE), and high natural extract (HNE) groups, respectively. Natural extract enhanced the quality of the meat: there was a significant decrease (P<0.05) in saturated fatty acids and a significant increase (P<0.05) in mono- and poly-unsaturated fatty acids. The oxidative stability of the meat improved, thus highlighting a possible link between the decrease (P<0.05) in TBARS values and an increase (P<0.05) in lipid vitamin content. The cholesterol content of the meat decreased markedly (P<0.01) after the dietary verbascoside treatment, thus improving the health benefits of the meat. These results clearly show the important role of Lippia citriodora extract, titrated in verbascoside, in improving the quality of the meat of intensively-reared hares. In addition the present paper underlines how the use of natural antioxidant in the animal feeding system may provide healthier and low-oxidized products to the final consumer

Surgical approaches to adenocarcinoma of the gastroesophageal junction: the Siewert II conundrum.

BACKGROUND: The Siewert classification system for gastroesophageal junction adenocarcinoma has provided morphological and topographical information to help guide surgical decision-making. Evidence has shown that Siewert I and III tumors are distinct entities with differing epidemiologic and histologic characteristics and distinct patterns of disease progression, requiring different treatment. Siewert II tumors share some of the characteristics of type I and III lesions, and the surgical approach is not universally agreed upon. Appropriate surgical options include transthoracic esophagogastrectomy, transhiatal esophagectomy, and transabdominal extended total gastrectomy. PURPOSE: A review of the available evidence of the surgical management of Siewert II tumors is presented. CONCLUSIONS: Careful review of the data appear to support the fact that a satisfactory oncologic resection can be achieved via a transabdominal extended total gastrectomy with a slight advantage in terms of perioperative complications, and overall postoperative quality of life. Overall and disease-free survival compares favorably to the transthoracic approach. These results can be achieved with careful selection of patients balancing more than just the Siewert type in the decision-making but considering also preoperative T and N stages, histological type (diffuse type requiring longer margins that are not always achievable via gastrectomy), and the presence of Barrett\u27s esophagus

Essays in market microstructure

This dissertation contains three theoretical essays on the functioning and the organization of over the counter markets. The first paper, "Is Time Enough to Alleviate Adverse Selection?," considers a dynamic adverse selection model in which sellers pay a search cost to find a new buyer. I uncover a relationship between adverse selection and the magnitude of search costs. Interestingly, small search costs may increase the severity of the adverse selection problem, ultimately leading to a lemons market. A market design intervention may mitigate adverse selection and promote full market participation. Conditional upon an adequate level of information disclosure, a per period market participation tax, coupled with a final rebate once a seller trades, introduces a credible signalling device. The second paper, "Peer Monitoring Incentives via Central Clearing Counterparties," studies how the novel introduction of mandatory clearing for over the counter financial assets may affect dealers’ incentives to monitor each other’s. The design of the loss allocation rules is crucial. To maximize peer monitoring incentives, a higher share of losses should be payed by surviving members with a greater trade exposure to the defaulting dealer. In practice, this mechanism can be implemented through variation margin haircutting. If all members should contribute, equilibrium outcomes may be inferior to what can be achieved without clearing. The third paper, "Learning and Price Dynamics in Durable Goods Markets," is joint work with Min Zhang. We set up a dynamic model with two key features: first, agents enjoy heterogeneous use values, and later resell the good; second, prices do not incorporate all available information. Informational frictions slow down learning, and affect price movements asymmetrically in high and low aggregate demand states. Learning and the resale motive are the predominant force for durable goods with short resale horizons, slow time-varying aggregate demand, and similar use values among buyers

Instantaneous centre of rotation in human motion: Measurement and computational issues

The instantaneous centre of rotation plays an important role in biomechanical modelling and physical-medical interpretation of human gestures. Therefore, we consider its measurement, based on video-image acquisition and processing of human motion records. Measurement and computational aspects are discussed, including the evaluation of measurement uncertainty and the estimation of the effect of some influence quantities on the determination of the position of the instantaneous centre of rotation
