New descent rules for solving the linear semi-infinite programming problem

1994

The algorithm described in this paper approaches the optimal solution of a continuous semi-infinite linear programming problem through a sequence of basic feasible solutions. The descent rules that we present for the improvement step are quite different when one deals with non-degenerate or degenerate extreme points. For the non-degenerate case we use a simplex-type approach, and for the other case a search direction scheme is applied. Some numerical examples illustrating the method are given.

Des chaînons manquants dans une sémiotique écologique: le cas des animaux

2021

To approach the very delicate question of the relationship between semiotics and the discourse of ecology, we should first ask the question of the four levels of the research in signification, and then to apply them to ongoing research on animality and zoosemiotics. The goal will be to reconstruct the strong theoretical and epistemological differences among a little number of semioticians.

Central Serotonin2C Receptor: From Physiology to Pathology

2006

Since the 1950s, when serotonin (5-HT) was discovered in the mammalian central nervous system (CNS), an enormous amount of experimental evidence has revealed the pivotal role of this biogenic amine in a number of cognitive and behavioural functions. Although 5-HT is synthesized by a small group of neurons within the raphe nuclei of the brain stem, almost all parts of the CNS receive serotonergic projections. Furthermore, the importance of 5-HT modulation and the fine-tuning of its action is underlined by the large number of 5-HT binding sites found in the CNS. Hitherto, up to 15 different 5-HT receptors subtypes have been identified. This review was undertaken to summarize the work that has…

High quality extra virgin olive oil from olives attacked by the olive fruit fly, Bactrocera oleae (Rossi) (Diptera Tephritidae): which is the tolerab…

2017

The infestation due to the olive fruit fly, Bactrocera oleae (Rossi), the key pest in most of world olive groves, has been monitored in six years, from 2004 to 2008 and in 2014, in eight coastal Sicilian olive groves consisting of ‘Cerasuola’ and ‘Nocellara del Belice’ cultivars. Infestation was recorded following the classical sampling method based on olive collection and dissection, in order to count live olive fruit fly instars (eggs, larvae and pupae) and exit holes. Four different infestation indexes, all of them calculated using data recorded at harvest, have been used to assess their relationship with the main three quality parameters of the olive oil obtained from the same olive sam…

Metilazione del DNA in artrite reumatoide

2005

Lo stato di metilazione del DNA genomico e del gene PTHrP è stato valutato con tecniche molecolari e citogenetiche in artrite reumatoide (AR), patologia autoimmune caratterizzata anche da alta incidenza di linfomi e da ipercalcemia per overespressione del gene PTHrP. La metilazione del DNA, infatti, ha un ruolo critico nello sviluppo delle malattie neoplastiche; il gene PTHrP avendo tre promotori uno dei quali contiene un’isola CpG è un buon candidato per la deregolazione da alterato pattern di metilazione locale. Le indagini sulla metilazione genomica, condotte su DNA estratto da sangue periferico di pazienti e di donatori e amplificato in reazioni di Methylation-Sensitive Arbitrarily Prim…

Settore BIO/18 - Geneticainstead chromosomes of controls were almost uniformly decorated by brilliant grains. Studies on methylation of PTHrP gene promoter 2 performed on five CpG island internal sites using the Methylation-Sensitive Restriction Endonuclease Multiplex (MSREM)-PCR showed that one of the sites nearest the trascription starting point is heavy methylated in a significantly high number of RA patients. Thus RA seems to be characterized by genomewide hypomethylation associated with local hypermethylation like the most part of tumors. This result raises the possibility that susceptibility to lymphomas is related to abnormal DNA methylation levels and suggests the opportunity to evaluate the DNA methylation status in RA patientin fact the demethylating therapies together with diet and life style can act towards an increase of tumor risk. Future studies using a larger number of subjects could confirm these findings.Rheumatoid Arthritis (RA) is a chronic multisystem inflammatory disease characterized by high recurrence of lymphomas as well as hypercalcemia due to PTHrP overexpression. Because of DNA methylation plays a critical role in development of neoplasias we determined in RA patients the global DNA methylation status and local methylation pattern of the CpG island of one of the three promoters of PTHrP gene utilizing molecular and cytogenetic techniques. Investigations performed on DNA from peripheral blood of patients and donors amplified by Methylation-Sensitive Arbitrarily Primed (MeS-AP)-PCR indicated that RA is strongly associated with global DNA hypomethylation. Similarly chromosomal DNA methylation pattern analysis by indirect immunofluorescence technique with anti 5-methylcitosine antibody showed all peripheral lymphocyte metaphases from RA patients with chromosomes weakly fluorescent without discrete grain

Sine cura. Verso il ri-ciclo dell'architettura del secondo Novecento

2019

Gli argomenti discussi nel saggio interrogano il destino che il Codice dei Beni Culturali (2004- 2011) determina per le opere del secondo Novecento. Nella costruzione del futuro di questi manufatti, che per funzione, tecnologia e cicli d’uso sono spesso segnati dall’obsolescenza e dall’abbandono, le ambiguità e le incongruenze delle attuali procedure legislative sollecitano profondamente il ruolo culturale delle esperienze di ricerca che usano metodologie meta progettuali. Il confronto fra alcuni casi italiani ed altri europei rimarca il ruolo del progetto nella costruzione di una prospettiva di tutela trasformativa per il costruito del secondo Novecento. Nel quadro di azione marcato dall’o…

Settore ICAR/14 - Composizione Architettonica E UrbanaThe essay questions the future's possibilities to operate on the buildings of the second half of the twentieth century according to the Italian Code of Cultural Heritage (2004-2011). When arguing how to encourage the re-use of these artifacts which are often marked by short-life technology cycles obsolescence and abandonment the ambiguities and inconsistencies of current legislative procedures deeply stress the cultural role of research experiences that use project-oriented methodologies. The comparison between some Italian and other European cases highlights the role of a design approach in the construction of a transformative protection perspective for the built matter of the second half of the twentieth century. In a framework aiming to encourage a reconciliation between the recent built environment and the new paradigms of sustainability and circular economy architecture must recognize re-cycle practices as a main theoretical and procedural node. To modernize the late Modern built environment with contemporary construction components is not simply a matter of technical knowledge and expertise: but a theme with theoretical density aesthetic and ethical values. The architectural project in this field today must ask for greater congruence between the bureaucratic and administrative levels and the real consistency of this corpus. It is a matter of identifying strategies to equip it with capabilities meanings and contents remembering that demolition wastes have unsustainable environmental costs and uncertain results concerning the necessary new attribution of political and semantic meaning that these places await.

Multi-Platform Agent Systems with Dynamic Reputation Policy Management

2011

Open, distributed multi-platform agent systems require new management approaches for resources and data secure access. In this paper a Jade-S based multi-platform agent system implementing dynamic reputation policy management is proposed. The implemented extension deals with biometrics, X-Security, DES cryptography and agent reputation. With more details, the proposed reputation management system helps to assess the agent's behavior and reliability, in order to select trusted agents. This is made possible by the knowledge that agents are able to acquire, over time, and that allows them to choose the best solution using own intelligence in total autonomy.

Scritti in onore di Pellegrino Capaldo

2014

La qualità dei servizi è stata riconosciuta come un rilevante aspetto caratterizzante la performance dell’azienda pubblica, analogamente alla capacità di operare secondo criteri di efficienza e nel rispetto dei vincoli di bilancio. Sebbene sia possibile riscontrare alcuni significativi casi di adozione di politiche di customer satisfaction nelle amministrazioni pubbliche italiane, a tutt’oggi il tema presenta significative criticità, specialmente in ordine agli aspetti metodologici e agli strumenti operativi che consentano di integrare dette politiche nel sistema di programmazione e controllo delle aziende che erogano tali servizi. Il presente lavoro adotta una diversa prospettiva di analis…

Settore SECS-P/07 - Economia AziendaleQuality in delivering public services has been recognised as a major issue challenging performance in the public sector as well as the ability to operate effectively and within budget constraints. Empirical findings shown by the literature demonstrate that concrete efforts have been produced towards the evaluation and improvement of satisfaction levels of citizens and other Public Administration’s ‘customers’. However still today this issue portrays many unresolved criticalities particularly concerning the methodological approaches and operative tools to adopt in order to integrate ‘customer satisfaction’ programs with the wider organisational control system in each public administration. This paper adopts a non-conventional view of the ‘customer satisfaction’ concept. This is currently meant as a matter of social reporting or even statistical analysis based on the users’ perceptions on the level of provided services by a given (front office) unit in the public sector. Here an inter-institutional perspective is adopted with a view to map the overall value chain leading to the final product delivered to citizens or the community. Inside this chain tracking the underlying administrative products delivered by back-office units to their ‘internal clients’ in the public administration is recommended as a fundamental step to understand how to improve performance in satisfying citizens’ needs. This should also require a proper link between the administrative units’ goals and performance measures to the desired efficiency and effectiveness of processes leading to the attainment of administrative products providing the basis of the final services delivered to the private sector. Based on first empirical findings from field analysis in the Italian context the paper aims to outline an approach which could assist both politicians and managers to better assess and improve performance according to a customer satisfaction perspective.
