A multi-agent decision support system for dynamic supply chain organization
2011
In this work, a multi-agent system (MAS) for supply chain dynamic con- figuration is proposed. The brain of each agent is composed of a Bayesian Decision Network (BDN); this choice allows the agent for taking the best decisions esti- mating benefits and potential risks of different strategies, analyzing and managing uncertain information about the collaborating companies. Each agent collects infor- mation about customer’s orders and current market prices, and analyzes previous experiences of collaborations with trading partners. The agent therefore performs a probabilistic inferential reasoning to filter information modeled in its knowledge base in order to achieve the best performance in t…
Respiratory Gas Transport in Heart
1973
The purpose of this paper is to describe an attempt to obtain a better understanding of the dynamics of the oxygen supply of the myocardium under physiological and pathophysiological conditions by examining the oxygen diffusion in the heart muscle tissue during systole and diastole. In comparison to other organs the oxygen supply of the myocardium is characterized by a number of specific features. The most important one is that the gas exchange in the myocardium is a nonsteady-state diffusion process.
The role of the hospital pharmacy in the storage and supply of antidotes
2013
Cases of poisoning have been analyzed with the aim of estimating both the incidence and the seriousness of such xenobiotic effects, the major determinant agents, and the related antidotes used in hospital departments. From 2009 to November 2012, a survey of the availability of antidotes in the emergency room services was carried out in all hospital pharmacies under the Palermo Health Authority: Policlinico Paolo Giaccone, ARNAS Civico di Cristina Benefratelli, Azienda Ospedaliera Ospedali Riuniti Villa Sofia-Cervello. Figures show that the majority of poisoning events were caused by the use/abuse of drugs, especially psychopharmaceuticals, alcohol and narcotic substances. This overdose of m…
Protective effect of antioxidants contained in milk-based fruit beverages against sterol oxidation products
2017
Abstract Sterol oxidation products (SOPs) have shown cytotoxic effect in human intestinal cells; however, their effect within a food matrix has not been assayed yet. This study evaluated the possible cytotoxic effect of SOPs within bioaccessible fractions (BFs) of two milk-based fruit beverages with (BFA)/without (BFB) plant sterols in differentiated Caco-2 cells and if the BFs counteracted the cytotoxic effect induced by COPs mixture (30 and 60 μM). BFs did not evoke cytotoxic effect in any of the tests carried out and they protected against the loss of intestinal cohesion, mitochondrial depolarization and necrosis induced by COPs mixture. Moreover, BFB sample protected from cell cycle arr…
Negotiation Models in Manufacturing E-Marketplaces
2005
This chapter describes the negotiation model adopted by the Customer and Supplier Negotiation Agents in the agent based architecture described in Chapter 2. The chapter is structured as it follows: in the first section the use of automated negotiation in modern market scenario is motivated; in the second section, starting form the contributions presented in the scientific literature, automated negotiation will be analysed and a taxonomy will be proposed. The third section is dedicated to the e-market context discussed in this book and in particular the impact of negotiation in manufacturing e-marketplaces will be stressed: its impact is strictly related to the electronic nature of e-marketp…
Self-Heating Induced Instability of a Non-Linear Inductor in a SMPS: a Case Study
2023
This paper proposes a case study to show that the non-linear operation of a power inductor in a SMPS can induce instability of the control system leading to overheating of the inductor beyond its allowable temperature and to an excessive peak of the maximum current. The case study is performed by a commercial ferrite inductor employed in a synchronous boost converter encompassing a control system to adjust the duty cycle, assuring a constant output voltage. The thermal transient is described by the time domain waveforms and thermal images.
Recent Advances in Biotechnological Methods for Wheat Gluten Immunotoxicity Abolishment – a Review
2021
Due to the increasing incidence of gluten intolerance, researchers are focusing on finding ways to eliminate immunotoxicity of wheat, this would allow the use of wheat products for gluten-intolerant consumers. The article reviews recent studies on biotechnological methods to eliminate and reduce the immunogenicity of wheat products. So far, many gluten removal methods have been proposed, but their efficacy levels were quite different. Enzymatic treatment of gluten fragments can be considered the simplest and non-invasive tool to eliminate the toxicity of gliadins and glutenins. For this purpose, various endogenous enzymes derived from cereals, and also those of bacterial, fungal, plant, and…
“Five Keys to Safer Food” and COVID-19
2021
On 11 March 2020, coronavirus disease 2019 (COVID-19) was declared a pandemic by the World Health Organization (WHO) and, up to 18:37 a.m. on 9 December 2021, it has produced 268,440,530 cases and 5,299,511 deaths. This disease, in some patients, included pneumonia and shortness of breath, being transmitted through droplets and aerosols. To date, there is no scientific literature to justify transmission directly from foods. In this review, we applied the precautionary principle for the home and the food industry using the known “Five Keys to Safer Food” manual developed by the World Health Organization (WHO) and extended punctually in its core information from five keys, in the light of new…
Bioavailability of plant sterol-enriched milk-based fruit beverages: In vivo and in vitro studies
2015
Abstract This study for the first time compares the in vivo (response in serum from individuals of an interventional study) and in vitro effects (bioaccessibility determined from simulated gastrointestinal digestion) of two plant sterol (PS)-enriched milk-based fruit beverages (with and without tangerine fruit juice rich in β-cryptoxanthin (β-Cx)) in order to assess their suitability as PS-enriched food matrixes, and the possible interactions between the two bioactive compounds (β-Cx and PS) that might affect their absorption. The randomized, double-blind, crossover study (performed in 36 postmenopausal women) showed the β-sitosterol and campesterol serum concentrations after four weeks of …
