Genesi geometrica delle volte centriche

1996

Un'analisi completa degli organismi voltati comporta lo studio delle molteplici componenti necessarie alla loro definizione: configurazione geometrica, sistema costruttivo, area storico-geografica di appartenenza, interpretazioni Stilistiche. L’obiettivo di questo studio è indirizzato all' analisi delle volte continue su pianta centrica definibili attraverso le leggi della geometria euclidea. L’indagine si pone all'interno dei confini relativi alla loro configurazione geometrica e il criterio adottato, svincolato da classificazioni di carattere tipologico o stilistico, propone l'identificazione di famiglie geometriche in base alla figura del poligono di base dell'impianto. Si può identifica…

A comprehensive analysis of vaulted bodies involves the study of the multiple components necessary for their definition: geometric configuration construction system historical-geographical area of belonging interpretations Stylistic. The objective of this study is directed to the 'analysis of continuous vaults on a centric plan definable through the laws of Euclidean geometry. The investigation arises within the boundaries related to their geometric configuration and the criterion adopted freed from typological or stylistic classifications proposes the identification of geometric families based on the figure of the basic polygon of the plant. An ordering process can be identified to explain the compositional process of curved-roofed central plants: that is the elaboration of a series of theoretical models developed according to an abacus referring to the basic geometries of the triangle square and pentagon is possible. It is not intended to impose a classification but to propose a study tool that thanks to a few simple compositional rules develops a very large number of configurationthe question remains as to why only a part has been used for the realization of vaulted covered centric buildings but this presumes considerations of a historical formal and constructive nature extraneous to this discussion.Settore ICAR/17 - Disegno

Angiotensin II dependent cardiac remodeling in the eel Anguilla anguilla involves the NOS/NO system

2017

Angiotensin II (AngII), the principal effector of the Renin-Angiotensin System (RAS), plays an important role in controlling mammalian cardiac morpho-functional remodelling. In the eel Anguilla anguilla, one month administration of AngII improves cardiac performance and influences the expression and localization of molecules which regulate cell growth. To deeper investigate the morpho-functional chronic influences of AngII on the eel heart and the molecular mechanisms involved, freshwater eels (A. anguilla) were intraperitoneally injected for 2 months with AngII (1 nmol g BW-1). Then the isolated hearts were subjected to morphological and western blotting analyses, and nitrite measurements.…

Analysis of emerging and related pollutants in aquatic biota

2020

Water bodies cover approximately 70 % of the earth s surface, making them ecosystems with a high environmental value and the habitat for numerous species of flora and fauna. Emerging pollutants (EPs) are ubiquitous anthropogenic compounds of environmental concern that can be found at different concentration levels in matrices such as sediment, water and aquatic biota. In addition, EPs can be bioaccumulated and biomagnified, inducing adverse effects on biota, and posing a risk to humans when contaminated biota is consumed. Unlike abiotic matrices, the occurrence of EPs in aquatic biota has not been widely studied. This is probably because their complexity, due to the presence of lipids, prot…

Ricerche in tema di società questuarie

2019

Intorno al regime delle società di tipo questuario – riconducibili agli schemi teorici della societas universorum quae ex quaestu veniunt – e delle società unius alicuius negotiationis e unius rei, si profusero gli sforzi interpretativi dei giuristi romani, fin dalla fine dell’età repubblicana. La monografia scientifica ripercorre le tracce della individuazione della nozione stessa di quaestus (guadagno), con particolare riferimento alla inclusione al suo interno delle donazioni cd. remuneratorie; ancora, ricostruisce il dibattito giurisprudenziale sorto intorno alla questione se i soci – nella determinazione delle quote – dovessero rispettare una proporzione rispetto ai conferimenti, con u…

About the regulations of the societas quaestus - referable to the societas universorum quae ex quaestu veniunt and to the societas unius alicuius negotiationis and unius rei - the interpretative efforts of the Roman jurists were given profusely since the end of the republican age. The scientific monograph puts itself on the traces of identifying the notion of quaestus (gain) with particular reference to the inclusion within it of the so-called remuneration gifts. Furthermore it reconstructs the jurisprudential debate that aroses around the question of whether the socii - in the determination of the shares - had to respect a proportion with the contributions and in this sense with an attempt to explain the existing contrast between a passage from the Digest and one of the Iustiniani Institutiones. Moreover always with specific reference to the societas quaestus the monograph investigates the setting-up of the intempestiva renuntiatio supporting its origin out of the contrast between Proculiani and Sabiniani so far postulated in doctrine. Finally the book closes with a chapter dedicated to the genesis of the term egestas which appears in a fragment of Modestinus (D. 17.2.4.1) dedicated to the causes of dissolution of the societas consensu contractaSettore IUS/18 - Diritto Romano E Diritti Dell'Antichita'

Metabolic shift of polyphosphate-accumulating organisms with different levels of polyphosphate storage

2012

Previous studies have shown that polyphosphate-accumulating organisms (PAOs) are able to behave as glycogen-accumulating organisms (GAOs) under different conditions. In this study we investigated the behavior of a culture enriched with Accumulibacter at different levels of polyphosphate (poly-P) storage. The results of stoichiometric ratios Gly degraded/HAc uptake, PHB synthesized/HAc uptake, PHV synthesized/HAc uptake and P release/HAc uptake confirmed a metabolic shift from PAO metabolism to GAO metabolism: PAOs with high poly-P content used the poly-P to obtain adenosine tri-phosphate (ATP), and glycogen (Gly) to obtain nicotinamide adenine dinucleotide (NADH) and some ATP. In a test whe…

Application of the General Model "Biological Nutrient Removal Model No.1" to upgrade two full-scale WWTPs

2012

In this paper, two practical case studies for upgrading two wastewater treatment plants (WWTPs) using the general model BNRM1 (Biological Nutrient Removal Model No. 1) are presented. In the first case study, the Tarragona WWTP was upgraded by reducing the phosphorus load to the anaerobic digester in order to minimize the precipitation problems. Phosphorus load reduction was accomplished by mixing the primary sludge and the secondary sludge and by elutriating the mixed sludge. In the second case study, the Alcantarilla WWTP, the nutrient removal was enhanced by maintaining a relatively low dissolved oxygen concentration in Stage A to maintain the acidogenic bacteria activity. The VFA produce…

Is the nonREM–REM sleep cycle reset by forced awakenings from REM sleep?

2002

In selective REM sleep deprivation (SRSD), the occurrence of stage REM is repeatedly interrupted by short awakenings. Typically, the interventions aggregate in clusters resembling the REM episodes in undisturbed sleep. This salient phenomenon can easily be explained if the nonREM–REM sleep process is continued during the periods of forced wakefulness. However, earlier studies have alternatively suggested that awakenings from sleep might rather discontinue and reset the ultradian process. Theoretically, the two explanations predict a different distribution of REM episode duration. We evaluated 117 SRSD treatment nights recorded from 14 depressive inpatients receiving low dosages of Trimipram…

Evapotranspiration from an Olive Orchard using Remote Sensing-Based Dual Crop Coefficient Approach

2013

A remote sensing-based approach to estimate actual evapotranspiration (ET) was tested in an area covered by olive trees and characterized by Mediterranean climate. The methodology is a modified version of the standard FAO-56 dual crop coefficient procedure, in which the crop potential transpiration, T p, is obtained by directly applying the Penman-Monteith (PM) equation with actual canopy characteristics (i.e., leaf area index, albedo and canopy height) derived from optical remote sensing data. Due to the minimum requirement of in-situ ancillary inputs, the methodology is suitable also for applications on large areas where the use of tabled crop coefficient values become problematic, due to…

Applications of a remote sensing-based two-source energy balance algorithm for mapping surface fluxes without in situ air temperature observations

2012

Abstract The two-source energy balance (TSEB) model uses remotely sensed maps of land–surface temperature (LST) along with local air temperature estimates at a nominal blending height to model heat and water fluxes across a landscape, partitioned between dual sources of canopy and soil. For operational implementation of TSEB, however, it is often difficult to obtain representative air temperature data that are compatible with the LST retrievals, which may themselves have residual errors due to atmospheric and emissivity corrections. To address this issue, two different strategies in applying the TSEB model without requiring local air temperature data were tested over a typical Mediterranean…
