Mating disruption of Planococcus ficus (Hemiptera: Pseudococcidae) in vineyards using reservoir pheromone dispensers
Get PDFMating disruption field experiments to control the vine mealybug, Planococcus ficus (Signoret) (Hemiptera: Pseudococcidae), were carried out in 2008 and 2009 in two commercial vineyards in Sardinia (Italy). The effectiveness of mating disruption was evaluated by testing reservoir dispensers loaded with 100 mg (62.5 g/ha) and 150 mg (93.8 g/ha) of the sex pheromone in 2008 and 2009, respectively. The number of males captured in pheromone traps, the P. ficus population density and age structure, the parasitism rate, the percentage of ovipositing females, and the crop damage were compared between disrupted and untreated plots. In both field trials, the number of males captured in mating disruption plots was significantly reduced by 86% and 95%, respectively. Mating disruption at the initial dose of 62.5 g/ha of active ingredient gave inconclusive results, whereas the dose of 93.8 g/ha significantly lowered the mealybug density and modified the age structure, which showed a lower percentage of ovipositing females and a higher proportion of preovipositing females. Mating disruption did not affect negatively the parasitism rate, which was higher in the disrupted than in the control plots (>1.5-fold). Crop damage at harvest was very low in both field trials and did not differ between treatments. Mating disruption was effective in wide plots protected with dispensers loaded with 150 mg of the sex pheromone, showing its potential to be included in the overall integrated control programs in Mediterranean wine-growing region

Learn PAd: Model-based Social Learning for Public Administrations
No full textIn modern society public administrations (PAs) are undergoing a profound transformation of their role, from rigid controllers to proactive service providers. PA servants have to cope with quickly changing contexts due to new laws and governance policies, societal globalization, fast technology evolution. Moreover, notwithstanding the constant decrease of public budgets, PAs are challenged by citizens to constantly improve their service quality. To face the above needs, PA servants need to understand and put in action latest governance procedures and rules within tight time constraints. The European FP7 Project Learn PAd enables a novel model-driven learning approach, through an open platform fostering cooperation and knowledge-sharing and exploiting process simulation for an effective training and assessment. Learn PAd considers learning and working strongly intertwined (learning-while-doing). The platform supports both an informative learning approach based on enriched business process (BP) models, and a procedural learning approach based on simulation and monitoring (learning-by-doing). The platform relies on formal verification and natural language processing techniques to ensure accuracy of content and documentation, and on specialized ontologies and KPIs purposely defined to keep learners engaged. Learn PAd is inspired by open-source communities principles and cooperation spirit: contents are produced by the community, and meritocracy is naturally promoted, with leaders in process competence emerging because of their skill and expertise
Modelling Process Intensive Scenarios for the Smart City
No full textSmart city can be considered as a process-intensive environment that needs to be as flexible as possible to support a continuously evolving scenario. In this paper we present an approach to support flexibility of Business Processes regulating the behaviour of ICT systems deployed within a smart city. The approach permits to deal with large collections of process variants thanks to the integration of Business Process notations and Feature Model descriptions. The approach is applied to a smart mobility scenario with a specific focus on bike sharing systems
An ontological approach for reliable data integration in the industrial domain
No full textOntologies are structural components of modern information systems. The taxonomy, the core of an ontology, is a delicate balance between adequacy considerations, minimal commitments and implementation concerns. However, ontological taxonomies can be quite restrictive and entities that are commonly used in production and services might not find room in an official or de facto standard or ontological system. This mismatch between the company\u27s view and the ontological constraints can limit or even jeopardize the adoption of modern formal ontologies in industry. We study the roots of this problem and individuate a general set of principles to relate the ontology and those non-ontological entities that are yet important for the core business of the company. We then introduce a theoretically sound and formally robust approach to expand a given ontology with new dependency relations, which make available information regarding the non-ontological entities without affecting the consistency of the overall information system

Studi epidemiologici su popolazioni umane esposte a basse e moderate concentrazioni di arsenico nelle acque potabili
Get PDFArsenic and its inorganic compounds are classified as human carcinogens. Several epidemiological studies conducted in areas of the world characterized by high arsenic concentration in drinking water, even up to 3,000 μg/l, report associations between arsenic exposure and skin, bladder, lung, liver and kidney cancer as well as cardiovascular diseases, diabetes and reproductive and developmental effects. Since general population is not exposed to these high arsenic concentrations in the last years attention focused on adverse health effects that low-to-moderate arsenic concentrations (0-150 μg/l) in drinking water could induce. The World Health Organization recommends a maximum limit of 10 μg/l for arsenic in drinking water. Almost all epidemiological studies conducted on populations exposed to low-to-moderate arsenic concentrations in drinking water are limited due to problems arising from both individual exposure assessment and low subjects number. The aim of the present review is to collect literature-based evidences regarding adverse health effects associated with exposure to low-to-moderate arsenic concentrations in drinking water (10-150 μg/l) in order to obtain a comprehensive picture of the health outcomes that such exposure can have on general population.L\u27arsenico e i suoi composti inorganici sono classificati come cancerogeni certi per l\u27uomo. Molti studi epidemiologici condotti in aree del mondo caratterizzate da elevate concentrazioni di arsenico nelle acque potabili, anche fino a 3.000 μg/l, riportano associazioni tra l\u27esposizione ad arsenico e cancro della pelle, della vescica, del polmone, del fegato e dei reni, cos? come malattie cardiovascolari, diabete ed effetti sia sulla riproduzione sia sullo sviluppo. La popolazione generale non ? solitamente esposta a queste concentrazioni di arsenico e negli ultimi anni sta crescendo sempre pi? la preoccupazione che anche moderate o basse concentrazioni di arsenico nelle acque potabili (10-150 μg/l) possano indurre esiti dannosi sulla salute umana. L\u27Organizzazione mondiale della sanit? raccomanda per l\u27arsenico nelle acque potabili il valore massimo di 10 μg/l. Quasi tutti gli studi epidemiologici condotti su popolazioni esposte a concentrazioni di arsenico nelle acque potabili, da basse a moderate, sono limitati a causa dei problemi derivanti sia dalla valutazione dell\u27esposizione individuale sia dalla bassa numerosit? delle popolazioni in studio. Lo scopo di questa rassegna ? raccogliere ci? che ? presente in letteratura per quanto riguarda gli effetti sulla salute associati all\u27esposizione a concentrazioni di arsenico, da basse a moderate, nelle acque destinate al consumo umano (10-150 μg/l) in modo da cercare di ottenere un quadro globale degli esiti che tale esposizione pu? avere sulla popolazione generale
A computational cardiovascular simulator for vad training.
No full textAim: VAD management training is a relevant issue involving all medical professionals deputed to advanced heart failure treatment. The aim of this work is the development of a computational cardiovascular simulator (CCS) to support learning of VAD management, focusing on VAD and circulatory system interactions. Methods: The CCS is a component of a comprehensive platform aimed at VAD management training. The lumped parameter computational circulatory model includes heart, systemic and pulmonary circulations and baroreflex. The CCS includes sub-models of continuous flow VADs, for both atrio-aortic and apical connections and of iv drug infusion. The CCS is able to simulate patients\u27 specific conditions or to generate preset or random pathologies offering to the trainee the possibility to manage the VAD and the related therapeutic actions such as drug or liquid administration. Further, the CCS can be used locally or remotely to enhance its training possibilities merged into a Learning Management System. Results: The whole model was verified with clinical and experimental data. It was used for training of medical professionals on specific clinical cases and on predefined hemodynamic pathological conditions. Conclusions: The CCS is flexible enough to be applied to different training needs. Its further development will include new autonomic controls and the respiratory system.
