Effect of gastric acid suppression on 13 C-urea breath test: comparison of ranitidine with omeprazole
2000
Background: The assessment of the effect of H2 antagonists on the results of the urea breath test has produced controversial results. Aim: To assess whether standard doses of both omeprazole and H2 blockers can adversely influence the accuracy of the urea breath test. Methods: Sixty dyspeptic patients with ascertained Helicobacter pylori infection were recruited for this prospective, open study. They were randomized to receive either omeprazole 20 mg at 08:00 hours (n = 30) or ranitidine 300 mg at 22:00 hours (n = 30) for 14 days. The urea breath test was performed at baseline, on day 14, while patients were still taking the antisecretory drugs, and on day 21, 1 week after their cessation. …
The genomic history of the Aegean palatial civilizations
2021
Summary The Cycladic, the Minoan, and the Helladic (Mycenaean) cultures define the Bronze Age (BA) of Greece. Urbanism, complex social structures, craft and agricultural specialization, and the earliest forms of writing characterize this iconic period. We sequenced six Early to Middle BA whole genomes, along with 11 mitochondrial genomes, sampled from the three BA cultures of the Aegean Sea. The Early BA (EBA) genomes are homogeneous and derive most of their ancestry from Neolithic Aegeans, contrary to earlier hypotheses that the Neolithic-EBA cultural transition was due to massive population turnover. EBA Aegeans were shaped by relatively small-scale migration from East of the Aegean, as e…
A taphonomic investigation of small vertebrate accumulations produced by the snowy owl (Bubo scandiacus) and its implications for fossil studies
2019
17 pages; International audience; The action of predators, such as diurnal raptors, owls, mammals or humans, influence the nature of smallvertebrate fossil assemblages but currently their taphonomic features are still poorly understood. In this study,we investigate the taphonomic signature of the snowy owl (Bubo scandiacus) based on an analysis of pelletscollected at breeding sites located in Greenland and the Canadian Arctic. This taxon is widely distributedthrough the North Hemisphere and was an important predator in Pleistocene times. Taphonomic parameterssuggest that, contrary to previous assumptions, B. scandiacus produces, on average, moderate digestion of incisors,molars and post-cra…

The influence of reverse flow on the dynamics of closed-loop supply chains
2014
The purpose of this paper is to study the impact of reverse logistics’ factors on the order and inventory variance amplification in a closed-loop supply chain. We adopt a difference equation math approach for analysing a closed-loop supply chain. Results show how the return flow positively affects both the inventory variance and the bullwhip effect independently of the number of echelons. On the contrary, an increasing remanufacturing lead-time negatively affects both the two metrics studied independently of the above mentioned settings. However, when the number of echelons increases, the benefit provided by the return flow tends to decrease.
Linee guida per la valutazione della resilienza delle foreste Mediterranee ai cambiamenti climatici [Guidelines for assessing the resilience of Medit…

We have defined optimal management models for improving or strengthening the resilience of forest environments: in particular, five best management practices aiming at improving the Mediterranean forests resilience with reference to the desertification risk. The 5 Best ManagementPractices are: BMP1 - Actions favoring mixing of species and hydrogeological stability of forests; BMP2 - Renaturalization of forest plantations; BMP3 - Remedial measures and restoration of degraded forests; BMP4 - Actions aimed at enhancing complex structural forests; BMP5 - Actions favoring connectivity in agro-forestry systems. The best management practices have been then applied adapting them to 16 different int…

The Relevance of Systemic Approaches in Business Sciences
2015
Our times are characterized by intense changes in the viable logics of markets and, generally speaking, of business systems. Business scenarios today are typified by connectivity, dynamism, nonlinearity, and emergent behaviors - in other words by “complexity” (Dominici, 2012). Reductionist models are unable to completely depict, or to allow us to totally understand the new business scenarios. Today, more than ever, it is necessary to recognize the need for a paradigm shift that can carry science beyond the analytical reductionist approach, and towards a more comprehensive systemic perspective. Systems thinking can be critical to unlock new perspectives and enhance holistic views for a bette…
La partecipazione ad un business ecosystem: implicazioni per la nozione di successo
2020
L’obiettivo del capitolo è offrire un’introduzione alla letteratura sugli ecosistemi aziendali e discutere critica-mente la tematica del successo e della misurazione delle performance del business ecosystem e degli attori che vi partecipano. A tale scopo, il capitolo è strutturato come segue. Il paragrafo 2 focalizza l’attenzione sulla definizione di business ecosystem. I paragrafi 3, 4 e 5 spiegano, rispettivamente, perché nasce un business ecosystem, chi sono gli attori e quali sono le strutture sottese agli ecosistemi aziendali. Il paragrafo 6 discute la misurazione delle performance del business ecosystem focalizzando l’attenzione sui seguenti aspetti: (a) indicatori di performance a li…
