Il sequestro e la confisca di partecipazioni e di aziende : primo inquadramento e riflessi contabili

2018

Nel contributo si esaminano alcuni aspetti gestionali e rilevativi delle aziende sottoposte a provvedimenti di sequestro e di successiva confisca. Sono inoltre criticamente esaminati alcuni provvedimenti normativi che caratterizzano la gestione delle aziende in argomento. Obiettivi del contributo sono: a. formulare alcune riflessioni circa il sequestro di quote di partecipazione, di aziende e di rami di aziende, avuto riguardo allo svolgimento dell’attività gestionale in condizioni di legalità, evitando il progressivo depauperamento del patrimonio; b. fornire alcune indicazioni circa la rappresentazione delle determinazioni quantitative di sintesi nei documenti riepilogativi contabili e, in…

ANALYSIS OF TOTAL ANTIOXIDANT CAPACITY AND TOTAL PHENOLIC CONTENT (TP) DURING RIPENING OF TWO SICILIAN RED GRAPES VARIETIES

2011

ANALYSIS OF TOTAL ANTIOXIDANT CAPACITY AND TOTAL PHENOLIC CONTENT (TP) DURING RIPENING OF TWO SICILIAN RED GRAPES VARIETIES During the last decade the interest for polyphenols has increased considerably because numerous epidemiological studies, supported by several short term controlled randomised clinical trials, have suggested associations between consumption of polyphenol-rich food or beverages and the prevention of certain chronic diseases associated with the oxidative stress condition (1). In a our previous study on several samples of Sicilian red wine we found that the total polyphenol parameter can not to characterize the nutraceutical properties of a wine by only because the correla…

The management of the slow transit constipation in the laparoscopic era

2018

The slow transit constipation (STC) is a functional bowel pathology with slow total gut transit time with normal calibre colon in addition to a variety of other systemic symptoms. Patients with an abnormal colonic motility refractory to conservative treatment are regarded as appropriate candidates for surgery. Laparoscopic total colectomy with ileum-rectum anastomosis represents the commonest surgical operation in the treatment of STC, in well selected patients, after failure of conservative treatment. From 2012 to 2016, 8 patients suffering constipation according to Roma III criteria and diagnosed as STC were submitted to a total colectomy in our O.U. We evaluated the long-term post-operat…

Determination of lidocaine in urine at low ppm levels using dispersive microextraction and attenuated total reflectance–Fourier transform infrared me…

2015

Abstract IR spectra provide valuable information about biological systems and can be obtained with compactable and affordable instruments, but the lack of sensitivity of this technique hampers its use in the determination of drugs in clinical fluids. Taking lidocaine as a target molecule, in this paper we introduced a methodology for determining drugs in urine samples using infrared spectroscopy. The lack of sensitivity of the IR was compensated with the combination of an effective and straightforward dispersive liquid–liquid microextraction and the measurement of the dry film of the organic extracts through attenuated total reflectance (ATR). The method developed improves the sensitivity b…

Effects of ocean acidification on embryonic respiration and development of a temperate wrasse living along a natural CO2 gradient

2016

Volcanic CO2 seeps provide opportunities to investigate the effects of ocean acidification on organisms in the wild. To understand the influence of increasing CO2 concentrations on the metabolic rate (oxygen consumption) and the development of ocellated wrasse early life stages, we ran two field experiments, collecting embryos from nesting sites with different partial pressures of CO2 [pCO2; ambient (400 µatm) and high (800-1000 µatm)] and reciprocally transplanting embryos from ambient- to high-CO2 sites for 30 h. Ocellated wrasse offspring brooded in different CO2 conditions had similar responses, but after transplanting portions of nests to the high-CO2 site, embryos from parents that sp…

Descriptor-type Kalman Filter and TLS EXIN Speed Estimate for Sensorless Control of a Linear Induction Motor.

2014

This paper proposes a speed observer for linear induction motors (LIMs), which is composed of two parts: 1) a linear Kalman filter (KF) for the online estimation of the inductor currents and induced part flux linkage components; and 2) a speed estimator based on the total least squares (TLS) EXIN neuron. The TLS estimator receives as inputs the state variables, estimated by the KF, and provides as output the LIM linear speed, which is fed back to the KF and the control system. The KF is based on the classic space-vector model of the rotating induction machine. The end effects of the LIMs have been considered an uncertainty treated by the KF. The TLS EXIN neuron has been used to compute, in …

The affine equivariant sign covariance matrix: asymptotic behavior and efficiencies

2003

We consider the affine equivariant sign covariance matrix (SCM) introduced by Visuri et al. (J. Statist. Plann. Inference 91 (2000) 557). The population SCM is shown to be proportional to the inverse of the regular covariance matrix. The eigenvectors and standardized eigenvalues of the covariance, matrix can thus be derived from the SCM. We also construct an estimate of the covariance and correlation matrix based on the SCM. The influence functions and limiting distributions of the SCM and its eigenvectors and eigenvalues are found. Limiting efficiencies are given in multivariate normal and t-distribution cases. The estimates are highly efficient in the multivariate normal case and perform …

Change-points detection for variance piecewise constant models

2011

A new approach based on the fit of a generalized linear regression model is introduced for detecting change-points in the variance of heteroscedastic Gaussian variables, with piecewise constant variance function. This approach overcome some limitations of both exact and approximate well-known methods that are based on successive application of search and tend to overestimate the real number of changes in the variance of the series. The proposed method just requires the computation of a gamma GLM with log-link, resulting in a very efficient algorithm even with large sample size and many change points to be estimated.
