Risk of Local Extinction of Odonata Freshwater Habitat Generalists and Specialists

2014

Understanding the risk of a local extinction in a single population relative to the habitat requirements of a species is important in both theoretical and applied ecology. Local extinction risk depends on several factors, such as habitat requirements, range size of species, and habitat quality. We studied the local extinctions among 31 dragonfly and damselfly species from 1930 to 1975 and from 1995 to 2003 in Central Finland. We tested whether habitat specialists had a higher local extinction rate than generalist species. Approximately 30% of the local dragonfly and damselfly populations were extirpated during the 2 study periods. The size of the geographical range of the species was negati…

Considerations regarding the alleged association between Herbalife products and cases of hepatotoxicity: a rebuttal.

2014

We thank Dr. K Appelhans et al. for their comments [1] on our paper [2], published online first in April 2012. In our review, we aimed to draw the attention of physicians to the uncontrolled and increasingly alarming use of herbal products and dietary supplements in the general population. In fact, in Italy this phenomenon, though still limited, has rapidly increased over the last few years. Here, use of herbal medicine products has increased to 3.7 %, while in other countries consumption is higher, reaching 20 % in the UK, and 40 % in the USA. Young non-smoking women with a high level of education appear to be the most common consumers [3]. It seems that women use these products more than …

Proteinuria-Microalbuminuria in Renal Damage

2015

Proteinuria (P) usually results from an insult in the glomerular and/or tubular structures of the kidney. It has been considered a marker of risk not only to develop renal insufficiency but also to suffer cardiovascular events, based on prospective studies carried out in the general population as well as in diabetic and hypertensive patients [1]. In fact, proteinuria has been considered a strong marker of risk and an intermediate endpoint during treatment [2, 3].

Exercise effects on cardiovascular disease: from basic aspects to clinical evidence.

2021

Contains fulltext : 283453.pdf (Publisher’s version ) (Closed access) Cardiovascular (CV) disease (CVD) remains the leading cause of major morbidity and CVD- and all-cause mortality in most of the world. It is now clear that regular physical activity (PA) and exercise training (ET) induces a wide range of direct and indirect physiologic adaptations and pleiotropic benefits for human general and CV health. Generally, higher levels of PA, ET, and cardiorespiratory fitness (CRF) are correlated with reduced risk of CVD, including myocardial infarction, CVD-related death, and all-cause mortality. Although exact details regarding the ideal doses of ET, including resistance and, especially, aerobi…

Fibre break failure processes in unidirectional composites: evaluation of critical damage states

2016

Earlier work which successfully modelled the kinetics of fibre breakage in unidirectional composites under monotonic tensile loading has been extended to quantify the kinetics of fibre failure during both monotonic and sustained tensile loading. In both cases, failure was seen to occur when a critical density of large clusters (more than 16 fibres are broken within the representative volume element) of fibre breaks developed. However, in monotonic loading failure occurred very quickly after the first development of these large clusters, whereas under sustained loading the composite could accommodate greater levels of large clusters because of the lower applied load. This article is part of …

Muon-electron lepton-flavor-violating transitions : Shell-model calculations of transitions in 27Al

2018

In this paper we present the results of large-scale shell-model calculations of muon-to-electron lepton-flavorviolating transitions for the case of the target nucleus 27Al. We extend the previous shell-model calculations, done in the sd model space, by including also the p orbitals in order to see whether the negative-parity states produce any significant effect in the conversion rate. The analysis of the results shows the dominance of coherent transitions mediated by isovector operators and going by the ground state of the target, with practically null influence of excited positive- or negative-parity states. peerReviewed

Analysis of light neutrino exchange and short-range mechanisms in 0νββ decay

2020

Neutrinoless double beta decay (0νββ) is a crucial test for lepton number violation. Observation of this process would have fundamental implications for neutrino physics, theories beyond the Standard Model and cosmology. Focusing on so-called short-range operators of 0νββ and their potential interplay with the standard light Majorana neutrino exchange, we present the first complete calculation of the relevant nuclear matrix elements, performed within the interacting boson model (IBM-2). Furthermore, we calculate the relevant phase space factors using exact Dirac electron wave functions, taking into account the finite nuclear size and screening by the electron cloud. The obtained numerical r…

Normativa emergenziale e diritti fondamentali

2020

L’A. affronta il tema della normativa emanata durante l'emergenza coronavirus e mette a fuoco l'esigenza primaria di garantire un bilanciamento tra il diritto alla salute con altri diritti fondamentali (in primis, libertà di circolazione, di riunione, religiosa, diritto al lavoro), concludendo che il bilanciamento si è risolto in una indiscutibile limitazione di quest’ultimi. In buona sostanza, secondo l'A., di fronte al conflitto tra il diritto alla salute e gli altri diritti fondamentali, la normativa emergenziale ha indiscutibilmente sacrificato questi ultimi.

Per una pedagogia dell'empatia

2005

L’empatia è esperienza ricorrente nella vita quotidiana e il sapere spontaneo ne comprende in qualche modo i tratti caratterizzanti. Dalla riflessione delle discipline psicologiche già viene in chiaro l’importanza pedagogica: la valenza educativa della conoscenza empatica, ma anche il significato empatico di ogni rapporto educativo. L’Autore, proponendo una pedagogia fondamentale di stile fenomenologico ed ermeneutico, istituisce l’empatia come categoria pedagogica. Analizzandone le intenzionalità costitutive, la riflessione fenomenologica perviene alla definizione di «interiorità personale oggettiva» e consente d’interpretarla virtù educativa per eccellenza. Essa forma infatti tanto la qua…
