Fede/fiducia, razionalità, conversione

2021

A partire da confronto tra alcuni passi dei Vangeli e testi di Wittgenstein e Kuhn, il saggio ragiona sulla su alcune questioni teoriche che ruotano attorno al tema della credenza e del cambiamento di credenza, a partire da una nozione molto densa del lessico greco antico, quella di pistis, che tra i suoi significati ha anche quelli di fede e fiducia. In particolare, si cerca di fare emergere come la dicotomia classica tra due tipi di pistis (da intendere qui genericamente come “credenza”), una pistis filosofico-scientifica razionale e una pistis religiosa irrazionale – distinzione che rimanda all’ancor più classica dicotomia “razionale” vs “irrazionale” – sia non soltanto difficile da sost…

Corporate Investment, Debt and Liquidity Choices in the Light of Financial Constraints and Hedging Needs

2015

We examine firms' simultaneous choice of investment, debt financing and liquidity in a large sample of US corporates between 1980 and 2014. We partition the sample according to the firms' financial constraints and their needs to hedge against future shortfalls in operating income. In contrast to earlier work, our joint estimation approach shows that cash flows affect the corporate decisions of unconstrained firms more strongly than those of constrained firms. Investment-cash flow sensitivities are particularly intense for unconstrained firms with high hedging needs. Investment opportunities (as proxied by Q), however, play a larger role for constrained firms with the effects being strongest…

Effect of tank size on food intake and growth in individually held juvenile rainbow trout Oncorhynchus mykiss (Walbaum)

Growth and food utilisation of rainbow trout (Oncorhynchus mykiss) fed low-fat herring and dry diets enriched with fish oil

1998

Two-year-old rainbow trout (initial weight 695 g) were fed for 15 weeks low-fat Baltic herring diets either with or without lipid enrichment. For comparison, similar groups of trout were fed dry pellets with and without top-dressing with fish oil. Inclusion of lipid increased growth rate in a similar manner for both types of diets. For the herring-based diet, increased lipid resulted in increased dry matter consumption but for the dry diet, feed efficiency (dry weight growth per dry weight food consumption) was improved by channelling more nutrients to lipid deposition. If compared within a stated lipid level, fish fed the herring-based diets grew at a slower rate than fish fed the dry diet…

Nanohybrid for Photodynamic Therapy and Fluorescence Imaging Tracking without Therapy

2018

Theranostic upconversion nanoparticles (UCNPs) are ideal candidates for personalized medicine. We present a smart, easy-to-prepare nanohybrid (NH) suitable for NIR-theragnosis and imaging tracking without triggering therapy simultaneously. The photophysical features of each component have been carefully selected in order to maximize the capabilities for theragnosis, in particular, the upconversion emission and the photosensitizer absorption. In addition, NH presents a fluorescent marker with one-photon absorption in the green and two-photon absorption cross-section at NIR wavelengths where the UCNP does not absorb, thus enabling innocuous tracking. Thus, the NH consists of NaYF4:Yb, Er, Tm …

Effects of repeated handling, with or without anaesthesia, on feed intake and growth in juvenile rainbow trout, Oncorhynchus mykiss (Walbaum)

2006

The effects of weekly anaesthetization with clove oil and tricaine methanesulphonate (MS-222) on feed intake and growth were examined in juvenile rainbow trout, Oncorhynchus mykiss (Walbaum), held individually. Repeated handling without anaesthetics significantly reduced feed intake and weight gain compared with an unhandled control group during an 8-week experiment. When anaesthetics were used during handling the feed consumption and weight gain were significantly (MS-222) or not significantly (clove oil) higher than in fish handled without anaesthesia. When compared with the unhandled control group, neither of these two anaesthetics had significant effects on feed intake but, in contrast …

Ultrafast internal conversion of excited cytosine via the lowest pipi electronic singlet state.

2003

Computational evidence at the CASPT2 level supports that the lowest excited state pipi* contributes to the S1/S0 crossing responsible for the ultrafast decay of singlet excited cytosine. The computed radiative lifetime, 33 ns, is consistent with the experimentally derived value, 40 ns. The nOpi* state does not play a direct role in the rapid repopulation of the ground state; it is involved in a S2/S1 crossing. Alternative mechanisms through excited states pisigma* or nNpi* are not competitive in cytosine.

A 3-week post-weaning restricted feeding as alternative to an ad libitum antibiotic-medicated feed: Effects on growth, carcass and meat of rabbits di…

2022

In this investigation, the impact of a 3-week post-weaning restricted feeding (RF) using an antibiotic-free feed, applied to rabbits from 36 to 56 days of age to preserve their health status as alternative to an ad libitum medicated feed with antibiotics (AMF), was verify in relation to rabbit genotype and slaughter age (SA). The RF and AMF treatments were compared evaluating their effects on feed intake, growth, mortality, carcass and meat quality of rabbits of two genotypes, Italian White purebred (IWP) and hybrid Hycole×IWP crossbred (HIWC), slaughtered at 78 or 92 days of age to obtain light or heavy carcasses. At 36 days of age, 256 weaned rabbits of both sexes were divided into 4 homo…
